Description

Disposable membrane type automatic flow-stop, anti-liquid residue transfusion device

Technical field

The present invention relates to a kind of medical disposable membrane type automatic liquid-stopping transfusion apparatus, relate in particular to a kind of disposable membrane type automatic flow-stop, anti-liquid residue transfusion device.

Background technology

One, liquid waste phenomenon and the reason of traditional infusion device

(1) aerofluxus after tube for transfusion air inlet in infusion process, discharge opeing and again topping up phenomenon: previous infusion bottle stops dripping and do not found in time by patient or nurse is busy while having little time continuous liquid, air can enter Murphy type burette [note: the present invention by its (as: usual Straight Murphy type burette, the Murphy type burette that offers grafting dosing interface, cone-shaped Murphy type burette etc.) referred to as dropping funnel.By the company's of being referred to as bottle devices such as plug bottle adapters, plug bottle connecting needle (it comprises side-hole needle, inclined-plane pin and is furnished with the airway etc. of air cleaning part).Transfusion catheter (as: the Straight transfusion catheter at dropping funnel, burette top will be arranged on, is furnished with the Straight transfusion catheter of a switch/fast actuator, Y shape transfusion catheter, is furnished with the Y shape transfusion catheter of a switch/fast actuator, be furnished with the Y shape transfusion catheter of transfusion bag and switch, be provided with the L shaped transfusion catheter of grafting dosing interface, be furnished with switch/the drip L shaped transfusion catheter etc. of fast actuator) be referred to as dropper, because they are all the transfusion catheters that is positioned at dropping funnel top, claim dropper.To be arranged on company's bottle device at dropping funnel top, company's bottle device (containing burette) at burette top, company's bottle device (containing dropper) of dropper upper end etc. is referred to as feed liquor interface, and so-called feed liquor is for dropping funnel.Transfusion catheter (as: the Straight transfusion catheter of dropping funnel liquid outlet will be connected to, lower end is connected with the Straight transfusion catheter of short section of elastic tube, be provided with the transfusion catheter of grafting dosing interface, can make its intracavity bubble, aeroembolism upper row's liquid gas convection current transfusion catheter automatically, lower end is connected with the liquid gas convection current transfusion catheter of short section of elastic tube etc.) be referred to as tube for transfusion.Usual joint (as: mammiform joint, cap button joint, moveable cap button joint), transfusion needle, infusion tee cock of being arranged on tube for transfusion end etc. are referred to as out to liquid interface] and transfusion lumen in.Its problem is: 1., in the time that tube for transfusion enters short section of air, nurse is often firmly wrapped in tube for transfusion from bottom to top on finger and makes tube for transfusion become the flat transfusion inner air tube of upwards extruding, and sometimes needs the success of repeatable operation ability, very inconvenient while taking power consumption; 2. in the time that tube for transfusion enters long section air, transfusion needle be must first separate and stagnant liquid and air in tube for transfusion discharged, then make tube for transfusion again topping up and continue drip defeated, not only operation sequence is loaded down with trivial details, while taking power consumption, easily cause interface and ward to pollute, and often affect the treatment and cause waste (note: the symbol "/" in file of the present invention refers to "or", below no longer heavily release) because the discharge of liquid especially repeats to discharge.

(2) the stagnant liquid origin cause of formation in transfusion bag, transfusion device and abandon phenomenon in infusion process: for preventing the trouble due to tube for transfusion air inlet, drip when defeated when adopting transfusion bag, the most of nurse especially nurse of emergency department is the airway of deliberately not planting, its result can cause the stagnant liquid of generation in transfusion bag, dropping funnel and whole piece tube for transfusion, nurses or because of patient call be with liquid to pull out next bag liquid of pin/changing-over, abandon in the lump together with stagnant liquid, residual liquid, according to survey, mostly (5 milliliters of left and right in transfusion bag 20 milliliters of left and right, 5 milliliters of left and right in dropping funnel, interior 10 milliliters of tube for transfusion).Especially the small size transfusion bag of precious liquid, its residual liquid amount with set that the ratio of amount of infusion is relative to be wanted greatly, this is a unacceptable but problem for inconvenient processing.

(3) blood back in infusion process and blood coagulation liquid road discharge opeing and the phenomenon that punctures again after stopping up: because tube for transfusion air inlet meeting makes the fluid column pressure decreased that shortens, or at patient's changing position (as clinostatism stands up, upper limb moves etc.) while causing venous pressure fluctuation, often there is blood back phenomenon, even a little blood back in transfusion needle stalk, if do not find in time in time continuous liquid, normal hyperamization liquid solidification liquid road is stopped up, again discharge opeing, aerofluxus, topping up and puncture, not only troublesome poeration, and can increase patient suffering and cause waste.

(4) the residual liquid origin cause of formation in infusion process or in transfusion latter stage infusion bottle and abandon phenomenon: owing to connecting the inlet of bottle device and be positioned at its tip, thereby can cause the bottleneck of infusing, bottleneck generates residual liquid, according to surveying its residual liquid amount mostly 2 milliliters of left and right, especially valuable residual liquid (for example: the price of current one bottle of 50 milliliters of albumin injection is 600 yuan is often left in the basket, if residual 1 milliliter, its direct losses are exactly 12 yuan), when previous infusion bottle stops dripping rear or infused latter stage [that time while referring to that the same day, last infusion bottle stopped dripping rear extremely transfusion end on the same day, (containing claims) below no longer heavily releases] abandon in the lump together with the residual liquid of infusion bottle and its intracavity, generally nurses can love, but have no way of disposing.In addition, the medical personnel of department of neurology discuss used albumin infusion bottle to other section office often, and residual liquid is spread upon on undergraduate course paralysed patient decubital ulcer skin ulcer face and promotes its healing, and this phenomenon is just enough to show its problem place.

(5) stagnant liquid, the residual liquid origin cause of formation in transfusion latter stage dropping funnel, tube for transfusion and abandon phenomenon: when 1. descending its pressure that shortens of fluid column equates with venous pressure in dropping funnel drips empty tube for transfusion, tube for transfusion hypomere just can present fluid stagnation phenomenon (note: the liquid holdup phenomenon presenting in tube for transfusion after previous infusion bottle stops dripping, the present invention by it referred to as stagnant liquid; The liquid holdup phenomenon presenting in latter stage tube for transfusion of infusing the same day, the present invention by it referred to as residual liquid), its residual liquid amount and venous pressure individual variation, site of puncture and the tube for transfusion hypomere closely related (note: therefore the so-called tube for transfusion epimere of the present invention refers to that dropping funnel drips that section of empty tube for transfusion that enters air after sky such as bent circuitous degree that wriggles, the so-called tube for transfusion hypomere of the present invention refers to that dropping funnel drips empty rear that section of tube for transfusion that presents stagnant liquid phenomenon, respectively accounts for tube for transfusion length 1/2nd; Not tube for transfusion being divided equally is 2,3,4 ... epimere and hypomere shown in after section; So the present invention's so-called " tube for transfusion epimere " and " tube for transfusion hypomere " are relative, its length is roughly, hereby explanation); Especially precious liquid or children's drip when defeated or primary infusion bottle in liquid residue, not only cause waste, and can affect the treatment; Residual for preventing precious liquid, nurse separately drives the washing pipes such as one bottle of G/NS conventionally, and not only operation sequence is loaded down with trivial details and cause new waste, and very unfavorable to the patient of limit sodium, limit sugar, limit liquid; 2. because some patients were always worries that air can enter human body and feel fear, or not yet dripping sky at dropping funnel, just to urge nurse be that it pulls out pin; Nurse or because the busy liquid of being with pulls out pin, very common together with the stagnant liquid in dropping funnel, tube for transfusion, phenomenon that residual liquid abandons in the lump.

" nurse studies magazine " delivered one section and has been entitled as the paper of " experimentation of Eliminating Micro-air into Vein during Venous Transfusion " in the 11st page of the 13rd the 1st phase of phase volume in 1998; The paper that " Quotation Analysis " (being sponsored by Ministry of Public Health) delivered one section and be entitled as " discharge method of long section air under infusion process Murphy type burette " in the 54th page of the 19th the 3rd phase of volume of March in 2003 can show the above-mentioned defect place of traditional infusion device.

Two, correlation technique defect

Anti-liquid residue formula transfusion device (patent No.: ZL00239693.9, the day for announcing: calendar year 2001 JIUYUE 26 days) defect is: 1. can not rinse and wash and splash into human body (call in the following text and can not rinse bottle and splash into human body) the infusion bottle chamber of precious liquid; 2. critical patient drips defeated more than ten bottles of liquid every day mostly continuously, because dropping funnel liquid inlet and outlet respectively has a check-valves, in dripping empty tube for transfusion, dropping funnel when air inlet, even if short section of air can not be gone up row, can only adopt the method that separates transfusion needle to discharge stagnant liquid and the air in transfusion lumen; Due to the discharge of stagnant liquid or repeatedly discharge, can affect the treatment and cause on the contrary waste, therefore think that it is not suitable for dripping continuously defeated use; 3. previous infusion bottle drip empty after air can enter and in tube for transfusion, make the fluid column pressure that shortens diminish, often cause blood back, even the obstruction of blood coagulation liquid road, discharge opeing again, aerofluxus, topping up and puncture also likely occur a little blood back in transfusion needle stalk, not only trouble, and can waste; 4. in season in midwinter, when ice-cold liquid enters behind heating installation ward, be dissolved in hydrone gap when gases are heated, they expand (especially the liquid programming rate in the flowing fluid ratio infusion bottle in tube for transfusion is fast) to separate out and form the bubble (the present invention by it referred to as " interior angry bubble ") that is attached to tube for transfusion inwall, because the effect of check-valves is difficult to it upwards to discharge, when patient with severe symptoms infuses in a large number, long-time drip a gas transmission and steep when cumulative, especially in the time that the downward impulsive force of its liquid of pressurization quick infusion increases, bubble has the danger that enters human body; 5. before transfusion, first company's bottle device of transfusion device is injected in inverted mouth of infusion bottle, then close tube for transfusion pinching dropping funnel, the air of its intracavity is got in infusion bottle and made a little rising of infusion bottle internal pressure, so that toward transfusion device internal-filling liquid.Because dropping funnel inlet is provided with check-valves, be difficult to the air in dropping funnel to get in infusion bottle, affect transfusion operation (referring to the preparation of infusing).

The defect of disposable multifunction safe transfusion system (patent No.: 02280389.0, the day for announcing: on October 29th, 2003) must be from microscopic techniques and the feasibility understanding that gets on: 1. can not rinse bottle and splash into human body, 2. sandstorm, haze weather have become the topic on current compatriots' the tip of the tongue, and on dosing inducing QI three ports 5, do not configure air cleaning part, be a kind of air guide port that exposes formula, after uncapping, be suspended in virus, pathogenic bacteria, dust in atmosphere, even small insect etc. has the danger that enters liquid road, 3. on dropping funnel liquid inlet and outlet, respectively have a check-valves, the defect of the problem that it causes and anti-liquid residue formula transfusion device is identical, no longer repeats, 4. be rational from the terminal phase of intravenous injection device for auto closing valve of its technical characterictic of design principle, but successively through three factories model test of nearly a year, its terminal phase of intravenous injection device for auto closing valve can not be realized the Expected Results of closing liquid road, its reason may be long with the slow negative pressure generative process of when transfusion liquid level downstream rate (it be rely on liquid level slowly descending and generate negative pressure), and negative pressure value float low and (referring to Figure of description 7) cone-shaped float-type terminal phase of intravenous injection device for auto closing valve is little relevant from heavy and light pressure, in addition, compared with pristine glass dropping funnel, the dropping funnel of existing transfusion device is made up of translucent soft material, be subject to a little the caving inward of suction function to become flat and offset a part of negative pressure, and then can reduce negative pressure value and affect and close effect, 5. membrane type terminal phase of intravenous injection device for auto closing valve is positioned at dropping funnel top, before transfusion, the relatively high negative pressure of pinching dropping funnel institute's moment generation can make membrane type terminal phase of intravenous injection device for auto closing valve in closed condition, inconvenience is toward transfusion device internal-filling liquid, affect transfusion operation, and become the five large factors of abandoning this patent right.At least the design people did not expect above problem originally, and not yet found pertinent literature and product at present, otherwise did not just have the application yet.

In recent years as many enterprises' SEPARATE APPLICATION (or having authorized) such as Jiangxi HTC a kind of identical automatic-exhaust transfusion device, they are that the outer wall center that is referred to as the admission chamber of precision liquid medicine filter (shape, as wrist-watch, is inside established two chambeies) at tube for transfusion hypomere has been driven one/air vent multiple or that be furnished with seal cover and formed.Using method is: 1. in previous infusion bottle drips empty defeated pipe, when air inlet and in the time not establishing seal cover on air vent, can directly continue liquid; 2. in previous infusion bottle drips empty tube for transfusion, when air inlet and in the time being furnished with seal cover on air vent, should first uncap and continue again liquid.They are to utilize the bidirection press of the interior aeroembolism of tube for transfusion top fluid column pressure and venous pressure that gas is extruded to air vent.Its exhaust mode divides and opens wide aerofluxus and two kinds of the aerofluxuss of uncapping while needing.Its defect is: 1. can not rinse bottle and splash into human body; 2. the latter stage tube for transfusion hypomere of infusing the same day has residual liquid phenomenon, and its residual liquid amount is closely related with the factor such as size, shape that is referred to as precision liquid medicine filter, according to the residual liquid amount of surveying certain enterprise product 8 milliliters of left and right; 3. previous infusion bottle drip empty after air can enter and in tube for transfusion, make the fluid column pressure that shortens diminish, have the blood back He Ye road of generation to stop up risk, or discharge opeing again, aerofluxus, topping up and puncture; According to three nurse's introductions of the second diabetes section of the People's Hospital of Nanning City, compared with traditional infusion device, automatic-exhaust transfusion device is (as the product of Shandong enterprise, even if dropping funnel does not drip sky) more easily there is blood back (mostly in the time of patient's changing position), its reason may be relevant with a little release of pressure effect of air vent (just as the air vent of high-pressure pot cover); 4. can not discharge the interior angry bubble in the tube for transfusion of exhaust apparatus below; 5. its exhaust mode is still open aerofluxus in any case, the position difference of just opening; Because its air vent is mostly positioned at tube for transfusion hypomere, when wounds oozing of blood, open sore part pyorrhea, gatism, sneeze, blows one's nose, and cough is spat, and the water of the choking food of choking, when nausea and vomiting or on one's sick bed defecation, has through air vent contaminated liquid transportation work style danger; Especially a large amount of transfusions of patient with severe symptoms are defeated with long-time, have safe secret worry.As everyone knows, the microorganism such as antibacterial, virus is ubiquitous all-pervasive, since gas can be discharged from air vent, the pathogenic microorganism such as antibacterial, virus is also likely invaded from air vent, even 1/10000000th probability, also avoid as far as possible, once the doctor that goes wrong, trouble, all very passive or engender tension relations of the tripartite of factory, the event that makes medical personnel's personal safety accident for a little problem happens occasionally; Transfusion is input after all, airtight higher than open safety, even if urethral catheterization and drain also can be emphasized the problem of a seal, can not make it always open wide; It is how important to safety that the inside and outside section general " closed drainage bottle " that medical worker was familiar with is just enough to show airtight; Therefore, should not adopt a casual attitude for any potential problems, leave things to chance; 6. its air vent sweet taste that especially air vent of open type appears, fishy smell (blood product) can noly be caused mosquitos and flies, Formica fusca, jumping and disturbed etc. and to need the time to observe; 7. in the time being unworthy of seal cover on air vent, easily misled by " automatically " two words, because air vent is positioned at tube for transfusion hypomere, once limbs of patient kills air vent, air has the danger that enters human body; In the time being furnished with seal cover on air vent, must open the gas Natural excrements such as seal cover and cover back again, name day automatically also must be manual, not only trouble, and can waste nurse's time.

The patent No. is that 201120265273.0 the disposable defect of exempting from the continuous liquid transfusion device of aerofluxus is: 1. can not rinse bottle and splash into human body; 2. after last bottle fluid drips sky, air can enter tube for transfusion epimere intracavity the fluid column pressure that shortens is diminished, and has the risk that causes blood back Ji Ye road to be stopped up; 3. tube for transfusion is too slightly not too refined; And become three main causes abandoning this patent right.

The patent No. is disposable use (float type) automatic liquid-stopping transfusion apparatus (producer: Europe, Zhejiang health care spirit armarium company limited of ZL200320131818.4, phone: 0576-85289098) float valve (float type stops liquid valve) of product is positioned at dropping funnel below, can not only prevent from bothering due to tube for transfusion air inlet, and fluid column high pressure can (refer to crouch by effectively anti-return blood greatly, seat drip defeated and infusion bottle drip empty after) and blood coagulation due to liquid road stop up, especially can prevent the environment that the continuous liquid mode such as open aerofluxus or open discharge opeing aerofluxus may cause, pollute and occupational infection on liquid road, have Partial Hospitals emergency department and adopted this product for alleviating operating pressure.But it has but occurred another more distinct issues after having solved a problem, that was infused and can cause latter stage generating residual liquid in whole piece tube for transfusion on the same day exactly, was 10 milliliters according to measuring its residual liquid amount in kind; Especially primary infusion bottle or infantile infusion, its residual liquid amount is relatively large with the ratio of setting amount of infusion.For example: if the same day, last infusion bottle was 50 milliliters, its direct losses are exactly 1/5th.

Safe Medical Devices Co., Ltd. of Zhejiang Province (phone: 0576-85998931) has released a kind of disposable membrane type automatic liquid-stopping precision filter infusion set [patent No.: ominous in recent years.Production licence: Zhejiang food medicine prison tool is produced and permitted No. 20100292.Equipment registration card: No. 3661122nd, state's food medicine prison tool (standard) word 2011].It is to connect a film valve (membrane type automatic liquid-stopping valve) to form in dropping funnel bottom.Its film valve is made up of film valve chest (being made up of translucent wettable solid material), diaphragm and film valve discharging tube.The diaphragm that is fixedly installed on film valve chest top is a kind of fibrous membrane that soaks seepage function that has, and not only has automatic liquid-stopping effect, and can filtering liquid medicine.Compared with above-mentioned (float type) automatic liquid-stopping transfusion apparatus, its feature is: 1. not only saved a liquid medicine filter, and looked more succinct; 2. when diaphragm can not be floated to dropping funnel intracavity by the air of film valve insertion after soaking, can only the row of descending; For avoiding being advanced into human body generation security incident under the air in film valve pocket, before transfusion, must, by its emptying, direct reach diaphragm bottom surface therefore deliberately film valve discharging tube is upwards extend into film valve insertion from film valve chest diapire center; The top that the inlet (totally 4) of film valve discharging tube is positioned at it is symmetrically and evenly and distributes along periphery; With respect to tube for transfusion, film valve chest inner chamber spaciousness can form the convection current of liquid gas; That is to say when in film valve pocket when feed liquor gas always above liquid, and it can be discharged downwards via four inlets, film valve discharging tube and the tube for transfusion inner chamber of film valve discharging tube top periphery; Can prevent that the bubble producing at the liquid being introduced in dropping funnel from water dropper liquid-column impingement from entering in tube for transfusion, when topping up and aerofluxus, (refer to the preparation of infusing) and need not be inverted dropping funnel, pinch dropping funnel and just can (practise and claim full-automatic exhaust), its operation be comparatively convenient.Its diaphragm can ooze down a defeated mechanism for liquid four: 1. atmospheric pressure; 2. diaphragm top is the liquid gravity in dropping funnel; 3. diaphragm below is descending the produced gravitation of fluid column gravity in tube for transfusion; 4. diaphragm soak function.For alleviating operating pressure, as the medical institutions such as emergency department of Baiyun District, Guangzhou City the People's Hospital have adopted this product.Meanwhile also think that it exists the too many defect of residual liquid amount really, also more than the residual liquid of above-mentioned float type automatic liquid-stopping transfusion apparatus.While dripping defeated end eventually, not only in dropping funnel bottom and whole piece tube for transfusion, have residual liquid, and film valve insertion is also full.According to surveying its residual liquid amount more than 12 milliliters (there is no filter on due to tube for transfusion, its residual liquid is 9 milliliters, and the residual liquid in dropping funnel and film valve is more than 3 milliliters).Understand the mechanism that this transfusion device can automatic liquid-stopping and generate the reason of more residual liquid and can find a practicable solution.It is considered herein that and be necessary to analyze its design principle: by comparison; only liquid effect of float type float valve is to realize by floating and the whereabouts automatic open close float valve liquid outlet of buoy; its float valve inner chamber and dropping funnel inner chamber connect mutually, and the gas of float valve intracavity can float up to dropping funnel intracavity automatically.The atmospheric pressure that drips empty its intracavity when infusion bottle also can directly enter float valve inner chamber through dropping funnel.Float valve liquid outlet is positioned at float valve intracavity bottom, and previous infusion bottle drips after sky, and float valve inner chamber is empty substantially, only in tube for transfusion, has residual liquid.As long as can make buoy leave float valve liquid outlet or establish a bypass Zai Tong mechanism above float valve liquid outlet, just can by from infusion bottle in other words external atmospheric pressure import in transfusion lumen from top to bottom, and then can make the residual liquid in tube for transfusion epimere automatically input human body.For further understanding the diaphragm performance of this pattern automatic liquid-stopping precision filter infusion set, we are connected to this transfusion device on infusion bottle, to be then inverted dropping funnel and film valve, make film valve be positioned at dropping funnel top and make the tube for transfusion of film valve below sagging, make it to become serpentine, then carry out topping up, the liquid interface that goes out that found that this transfusion device end has bubble to discharge, and this shows that its diaphragm is not only ventilative but also permeable.Its diaphragm why can automatic liquid-stopping, and its principle is: with respect to not soaking liquid (as hydrargyrum etc.) and not soaking solid (as paraffin etc.); Belong to and soak liquid (also claiming wetting liquid) for dripping a defeated medicinal liquid, dropping funnel, film valve chest, drain pipe, diaphragm all belong to and soak solid (referring to can be soaked/moistening).As everyone knows, soak liquid and not only there is attraction adhewsive action to soaking solid, and in the tube chamber that soaks solid, have and on attached wall, draw effect (being so-called capillarity), and then can make intraluminal liquid level present ascendant trend and form recessed month shape liquid level.When soak liquid just form one after being full of diaphragm fiber space each other can sepage but air-locked fiber moisture film and liquid (referring to that atmospheric pressure can not reach down in film valve pocket) only.The Another reason that the upper end of film valve discharging tube is upwards extend into diaphragm bottom surface is, can make film valve insertion to soak liquid always full and then can make to soak that liquid always contacts diaphragm in case its de-liquid ventilative.Here it is there is another origin cause of formation of residual liquid in film valve insertion.The power of wetting speed and effect with soak liquid, soak the factor analysis such as character, the structure connection of solid.And in dropping funnel, also have the main cause of residual liquid to be: 1. soaking liquid can be along drawing on dropping funnel medial wall, diaphragm top, and then makes liquid level increase, due to so-called capillarity; 2. with the selection of diaphragm fiber and to soak usefulness relevant.Another defect of being somebody's turn to do " transfusion device " is: can not eliminate the interior angry bubble in tube for transfusion, be not suitable for using season in midwinter.The defect of being somebody's turn to do " transfusion device " is also: 1. on feed liquor interface, do not have setting to rinse bottle and splash into device, can not solve valuable residual liquid problem in infusion bottle; 2. check-valves is not set on tube for transfusion, when the upper toilet of patient or when carrying out auxiliary examination and taking a position that bottle drips defeated its infusion bottle and reduce, often has blood back, blood coagulation liquid road clogging; 3. check-valves is not set on tube for transfusion, when patient take bottle drip the patient of defeated especially private room slip or faint in toilet (as: hypoglycemia, hypotension, cough, urinate, position, pain, direct stimulation faint ... dizzy blood, during brain is sudden, heart infarction etc. is brought out in constipation), when the position of its infusion bottle significantly reduces or batters down, there is generation blood (referring to that blood samples of patients is backflowed in or beyond transfusion device lets out, below no longer heavily release) phenomenon.Patient's loading every day amount is that doctor calculates according to factors such as weight in patients, the state of an illness, age, relevant organ dysfunctions; Therefore, nursing college especially prim and proper teacher has strict demand to Nurse training, that is in the time that transfusion device internal-filling liquid and aerofluxus are gone in transfusion (referring to the preparation of infusing), just see that transfusion needle point has overflow of drug fluid should immediately close liquid road, the medicinal liquid of discharging can not exceed 3 (water dropper of national new technical standards is 20 of every milliliter of medicinal liquids), toward once success of the operation of transfusion device internal-filling liquid, otherwise examine defective, must the qualified permission graduation of make-up examination.Therefore have more hospital especially the Affiliated Hospital of emphasis medical college and school mostly decline this product.Even there is the patient who is expert to refuse to use this product.The deputy director of National Development and Reform Committee Zhu Zhixin has disclosed surprising data in the early time, and within 2010, China infuses 8 bottles per capita ... (seeing Guangzhou Daily B24 on January 15th, 2011).By every 2 bottle liquid medicines join 1 transfusion device (this be consider critical patient mostly drip every day defeated many bottles and most of outpatient service and basic medical unit and partial hospitalization patient are mostly dripped defeated 1 bottle at every turn) every residual 13 milliliters of year of transfusion device per capita 50 milliliters of medicinal liquids of (4 transfusion device) waste (containing transfusion bag, stagnant liquid in infusion bottle, aerofluxus in residual liquid and infusion process after tube for transfusion air inlet, the discharge opeing of liquid road after stifled and the waste of puncture due to waiting again due to discharge opeing and blood back) estimate, it will be a huge numeral, certainly the medicinal liquid of its direct losses is surprising equally.Outside anthropic factor (as patient lacks correct health idea requirement garter, going after profit or gain property of public hospital, private hospital commercial activity etc.), closely related with existing transfusion system structure defect.Along with scientific and technological progress, economic development, health of people consciousness strengthens, medical support system improvement and popularization, the people who operates, beats garter also can be increasing, and its wasting phenomenon also can be on the rise, and is the eager problems that solve of needs.

Summary of the invention

The special construction and the defect that the present invention be directed to disposable membrane type automatic liquid-stopping precision filter infusion set design.The object of the invention is: solve disposable membrane type automatic liquid-stopping precision filter infusion set and infused and can cause the problem that generates residual liquid in dropping funnel, film valve (for the abbreviation of membrane type automatic liquid-stopping valve) and whole piece transfusion lumen latter stage on the same day; And can avoid the air-guide type and the open exhaust mode that expose may cause the pollution of Ye road.The present invention also aims to: 1. drip defeated valuable or when therapeutic dose is had to the medicinal liquid of strict demand, can be by defeated the residual liquid in infusion bottle, " transfusion device " clean; 2. can tackle, collect and can eliminate the interior anger bubble in tube for transfusion, defeated for long-time of a large amount of transfusions of patient with severe symptoms in season in midwinter; 3. before transfusion, air in dropping funnel can be got in infusion bottle and make its intrinsic pressure a little rising, be conducive to transfusion device topping up, avoid affecting transfusion operation (referring to the preparation of infusing); 4. in the time of pressurization quick infusion rescue patient, can avoid careless manipulation/operate too quickly mistake the gas in tube for transfusion is pumped into human body; 5. can avoid blood accident.

Detailed description of the invention

Embodiment 1:

As shown in Figure 1, usual feed liquor interface is made up of side opening needle for inserting bottle 1, dropper 2 and the purification type airway (conduit of balance infusion bottle external and internal pressure, practise claim exhaustor) of being furnished with air cleaning part 3.Also side opening needle for inserting bottle 1 directly can be set to dropping funnel 4 tops and purification type airway and jointly form feed liquor interface.The purification type airway even if the transfusion of employing transfusion bag also should be planted, to reduce residual liquid amount in transfusion bag.Be furnished with the tube for transfusion that drips fast actuator 12 (dripping fast actuator for usual wheel clamping type) by usual transfusion catheter 13 and short section of elastic tube 15 (its effect is: 1. when venipuncture pinching it can rebound and can impel blood back to confirm whether successfully puncture; 2. can malleation pull out pin, that is pin is pulled out on pinching limit, limit in case ecchymoma or pin mouth oozing of blood) form.Nipple (circular cone) the shape joint 14 of taking out liquid interface can be for the socket of transfusion needle pintle.Film valve 9 is positioned at dropping funnel 4 belows.Film valve drain pipe 10 inlets 8 (several) are close to diaphragm 7 bottom surfaces.Controllable type liquid Lu Zaitong mechanism is for being opened on film valve drain pipe 10 liquid outlets on (being that section that film valve drain pipe 10 is positioned at film valve diapire below, not separately mapping)/film valve chest and being furnished with air cleaning part and controllable type purification type air guide port 6 that opening and closing element (seal cover 5) can supply nurse open and close.Infused the same day and open seal cover 5 latter stage and just ambient atmosphere can be purified and can be by it from top to bottom (from film valve insertion 11, film valve drain pipe 10 inlets 8 and tube for transfusion upper end) import in transfusion lumen, and then can make the residual liquid Automatic-descending of tube for transfusion epimere, stop pulling out transfusion needle when descending and finish transfusion on the same day when observing tube for transfusion inner liquid medicine.Can reduce residual liquid amount over half.Under residual liquid, action edge is: the action of gravity of fluid column in atmospheric pressure and tube for transfusion.

Embodiment 2:

As shown in Figure 2, usual feed liquor interface 17 forms by being furnished with the plug bottle adapter 19 of purification type air guide port 18 (practise claim air vent) and being furnished with switch or dripping the dropper of fast actuator 12 and indicate the burette 20 that scale is provided with suspender 16.Switch or a fast actuator 12 are adopted liquid measure for controlling.The dropping funnel 22 of being furnished with microdroplet water dropper 21 drips defeated for children's.Film valve is positioned at dropping funnel 22 belows.Controllable type liquid Lu Zaitong mechanism for be arranged on film valve drain pipe 27 liquid outlets (not separately mapping)/film valve chest and film valve liquid road, top (referring to dropping funnel 22 or feed liquor interface 17) upper and be furnished with that switch 24 (slide fastener also can be the switches such as chuck) can open and close for nurse around film (referring to get around the diaphragm 25 of film valve) controllable type bypass type airway 23; Infused the same day opened latter stage just can by from infusion bottle or from the atmosphere in burette (being the atmosphere purifying through the purification type air guide port at purification type air guide port 18 or burette top) from top to bottom (from film valve insertion 26, the inlet of film valve drain pipe 27 upper ends and tube for transfusion 28 upper ends) import tube for transfusion 28 intracavity, just can make the residual liquid Automatic-descending in tube for transfusion 28 epimeres.Can reduce residual liquid amount over half.Reversible pump form by being arranged on the switch 29 of tube for transfusion 28 epimeres (account for tube for transfusion length 1/2nd) bottom (refer under epimere 1/3rd) following (containing upper pars infrasegmentalis) on can spheroid 34, spheroid inlet, spheroid liquid outlet and the spheroid upper and lower liquid road of confession nurse extrusion pump liquid.Infused the same day and first close closed solid sphere 34 liquid roads, top latter stage, then hands pinching spheroid 34 of nurse can be by residual liquid input human body in its below tube for transfusion, defeated when clean when observing in tube for transfusion residual liquid, nurse's another hands closes closed solid sphere 34 liquid roads, below immediately with blood return prevention, then pulls out transfusion needle and finishes transfusion on the same day.In contrast, in the time that the interior angry bubble in discovery spheroid 34 top tube for transfusions increases, first close closed solid sphere 34 liquid road, the below pressure energies that pinching spheroid 34 produces again and upwards go out interior angry bubble the in its top tube for transfusion.Spheroid 34 is positioned at the reason of pars infrasegmentalis on tube for transfusion, and latter stage its inner chamber of infusing the same day is empty, and input residual liquid is comparatively convenient, save time, safety.If too high being unfavorable for of the position of spheroid 34 operates, what when this is because inputs residual liquid, nurse's eyes were dig-inned is the liquid gas mobility status in infusion needle guide tube.If spheroid 34 is set to tube for transfusion hypomere, must alternately open and close spheroid 34 upper and lower Ye roads and repeat pinching spheroid 34 and residual liquid could be inputted to human body, this 34 is full (also having residual liquid) because of the latter stage spheroid of infusing the same day, must be by could be by defeated the residual liquid in tube for transfusion clean after emptying spheroid 34, comparatively time-consuming and dangerous, because have some patients were (as children's), disease (as left heart failure) or medicine be can not input too fast, if control bad or cause problem.In the time that spheroid 34 is positioned on tube for transfusion pars infrasegmentalis, the volume of spheroid 34 is advisable to be a bit larger tham tube for transfusion hypomere volume, because can not be by its intracavity gas emptying when pinching spheroid 34.Slightly little spheroid also can adopt, and when input residual liquid, repetitive operation is once above is.If specialize in patient's transfusion in season in midwinter, also spheroid 34 can be set to especially tube for transfusion hypomere (account for tube for transfusion length 1/2nd) bottom (refer under hypomere 1/3rd) of tube for transfusion hypomere any part, its volume is advisable with the volume that is a bit larger tham tube for transfusion, first closes closed solid sphere 34 liquid road, the below pressure energies that pinching spheroid 34 produces again the interior angry bubble in tube for transfusion is upwards gone out to dropping funnel intracavity; When input residual liquid, repetitive operation is once or once.Spheroid 34 tops are provided with drips a fast actuator 35 (be the import adjustable type titration actuator of transferring the files, its upper and lower can relatively rotate and regulate as stone mill type, screws and can be adjusted to a maximum in, is minimal to and closes, domestic existing similar products).Take out the moveable cap button joint 32 of liquid interface, its cap is buckled 31 (nuts) and can not only be relatively rotated as horizontal direction around the vertical pivot of mammiform joint 30, and can slide up and down along that outer wall of mammiform joint 30 inlets 33, its positive effect is: can not only spin with the spiral shell button-type pintle of transfusion needle in case accidental, and can be for that infundibulate pintle socket with disjunctor protecting cover.Youngster with the reason that film valve, controllable type liquid Lu Zaitong mechanism and reversible pump be even more important is set on burette type transfusion apparatus be: 1. can prevent due to the blood back after tube for transfusion air inlet that liquid road is stopped up, because of the tiny cooperation difficulty of child vein, more comparatively trouble of puncture; 2. infantile infusion total amount is few, and residual liquid amount is relatively large with the ratio of setting amount of infusion, residual liquid is inputted to human body as far as possible; 3. can be by the upper row of interior angry bubble in tube for transfusion.In addition, drip when fast actuator when spheroid 34 tops are provided with, can omit the switch 29 of its top, this is also to have the function of closing liquid road because drip a fast actuator.But when this kind drips a fast actuator 35 while being positioned on spheroid 34 liquid roads, below, preferably retain the switch 29 on spheroid 34 liquid roads, below, this is because close while dripping fast actuator 35 blood return prevention and need both hands to coordinate, not too convenient.If adopt usual wheel clamping type to drip fast actuator, in the time upwards driving its roller (referring to close a fast actuator), can cause blood back, if wheel clamping type is dripped after fast actuator is inverted and is arranged on spheroid 34 liquid roads, below, in the time of the downward roller (referring to close a fast actuator) that drives it, there is the danger that air is pressed into human body, therefore must reserve appropriate amount of fluid in the time that pinching spheroid 34 is forced into residual liquid, more difficult accurate grasp.Therefore think that spheroid 34 belows are the most suitable with cutoff switch.With embodiment 1 phase specific energy by defeated residual liquid in tube for transfusion clean.Be understood that, even if do not arrange around film controllable type bypass type airway 23, the pinching spheroid 34 relatively high negative pressure that generates also can go out to make it ventilative by the loss of thick fluid that soaks on film valve film 25, and then can be by defeated residual liquid in tube for transfusion clean.Therefore, the present invention believes firmly, for a person skilled in the art, can realize a reason by accompanying drawing 2.Accompanying drawing 2 is actually and has provided at least three kinds of detailed description of the invention that is to say.That is: liquid Lu Zaitong, break-in double (refer to can the row of descending also can the row of going up) and the two is in conjunction with three kinds of embodiments.So-called " at least " also refers to and can segment according to the particular location of spheroid again.As shown in Figure 2,3, the spheroid liquid outlet of its reversible pump also can be a kind of tongue formula spheroid liquid outlet 36.Drip continuously season in midwinter and it is put in to spheroid 37 inner chambers middle parts when defeated and can tackle the interior angry bubble of collecting from tube for transfusion.When input residual liquid, first spheroid 37 is adjusted to perpendicular position and makes tongue formula spheroid liquid outlet 36 retract former potential energy by defeated residual liquid clean.Therefore can think it be a kind of can gas collection upwards aerofluxus can also be by defeated residual liquid clean multi-functional reversible pump again.

Embodiment 3:

As shown in Figure 4, usual feed liquor interface is made up of plug bottle adapter 38 and dropper 40 (being provided with the L shaped transfusion catheter of grafting dosing interface).Film valve is positioned at dropping funnel 4 belows.Tube for transfusion end is connected with usual fast actuator 35 (the transfusion extension tube that is provided with the adjustable type titration actuator of transferring the files, is used for intensive care unit, operating room).Moveable cap button joint 32 serves as liquid interface.As the another kind of design of the present invention, a kind of imitative gallbladder formula can be set on feed liquor interface and rinse bottle eropper 42, it is made up of reservoir 43, capsule pipe 41 and the switch 39 (being designated hereinafter simply as switch) that can open and close capsule pipe.Reservoir 43 is a kind of storage liquid (appearance) devices that be made up of medical flexible material and that connect with feed liquor interface 38.Using method and effect are: 1. drip before defeated precious liquid first and to set up venous transfusion passage (for routine operation mode) pinching reservoir 43 with sodium chloride injection to make its intracavity be full of sodium chloride injection for subsequent use, venipuncture success and changing-over precious liquid drip defeated after, remaining sodium chloride injection in infusion bottle is used for set up venous transfusion passage with other patient of section office, meet the saving spirit that country advocates; 2. after the infusion bottle of precious liquid stops dripping, pinching reservoir 43 is rinsed and is washed and splash into human body it, can not only avoid waste, and can prevent from changing due to bottle washing pipe and bother, and then it is (as tight in bottleneck sterilization to prevent that repeated puncture transfusion bottle stopper from may cause Ye road to be polluted, bottle stopper puncture hole seepage, crumb of bottle stopper etc. due to repeated puncture); 3. the volume of reservoir 43 or can be slightly large, at twice, rinse bottle and splash into, though infused the same day, have residual liquid in tube for transfusion latter stage, and it is sodium chloride injection, that is to say that it can not only be by valuable residual liquid input human body in infusion bottle, and can be by valuable residual liquid input human body in tube for transfusion.Though infused the same day, have residual liquid in film valve pocket latter stage, and it is the residual liquid being diluted.Meanwhile also an applicable defeated more than one bottle precious liquid or pressurization are dripped defeated.Operation sequence is: that section of dropper that first folding closes capsule pipe 41 belows again pinching reservoir 43 can make infusion bottle internal pressure raise.The gas system of reservoir 43 intracavity of finished product has pressure transfusion function concurrently through the gas of sterilization.

Embodiment 4:

Fig. 5,6,7,8,9 and 10 shows fourth embodiment of the invention.As shown in Figure 5, usual feed liquor interface is made up of the dropper that is provided with the plug bottle adapter 52 of purification type air guide port 46 and is furnished with switch 29 (comprise and be positioned at two kinds of set-up modes above or below capsule pipe, not separately mapping).Tube for transfusion is made up of usual transfusion catheter 54 and short section of elastic tube 56.The cap button joint 57 that serves as liquid interface is positioned at tube for transfusion (because accessory and position etc. thereof on tube for transfusion are different, the length of each section of tube for transfusion there are differences, though without specific meanings, for ease of identification and examination, therefore do not adopt identical caption numbering) end.Tube for transfusion is provided with and drips fast actuator 12.On feed liquor interface, be provided with imitative gallbladder formula and rinse a bottle eropper, it is made up of reservoir 44, capsule pipe and switch 24.Reservoir 44 is made up of medical flexible material.Switch 24 can prevent that the liquid return of washing away infusion bottle chamber is in reservoir 44.Film valve 48 is positioned at dropping funnel 45 belows.Controllable type liquid Lu Zaitong mechanism for be opened on film valve 48 diapires, can connect with film valve drain pipe liquid outlet 50 and be furnished with switch (be furnished with handle 51 and have the cock-type switch of delivery hole 49) can confession nurse open in advance, with closing and then can infusing the residual liquid Automatic-descending that makes film valve 48 intracavity latter stage to the external controllable type bypass type fluid guidance port 47 in transfusion lumen on the same day.Lower row's pump 55 (manually one-way pump) can form for the check-valves 53 on spheroid 34 and the liquid inlet and outlet thereof of nurse's manual squeezing pump liquid by being arranged on pars infrasegmentalis following (containing pars infrasegmentalis on tube for transfusion) on tube for transfusion.The negative pressure that pinching spheroid 34 generates can deviate to make it ventilative downwards by the liquid that soaks on film valve film, and then residual liquid can be inputted to human body.Repeat the pinching spheroid 34 quick infusion rescue patient of pressurizeing.Due to the purposes difference of its operation facility and clinical transfusion, therefore the position of the volume to spheroid 34 and setting is not particularly limited.For example: if 1. for continuous transfusion and pressurization quick infusion and anti-residual liquid, the volume of spheroid 34 can be slightly large, with tube for transfusion hypomere (account for tube for transfusion length 1/2nd) top (refer on hypomere 1/3rd) or tube for transfusion hypomere middle part (refer in hypomere 1/3rd), being advisable (is preferred site in the present position of spheroid 34 and check-valves, because north and south exists height differences), can not only avoid medical personnel's elevation arm to grab continuously squeezing the aching and limp muscular strength fatigue of arm due to spheroid 34, and can monitoring patients and the operation that prevents from bending over due to uncomfortable; Use if 2. specialize in a high youngster nurse, also can be set to even tube for transfusion epimere top (refer on epimere 1/3rd) of pars infrasegmentalis on tube for transfusion, tube for transfusion epimere middle part (refer in epimere 1/3rd); If be 3. exclusively used in anti-residual liquid, the volume of spheroid 34 should be little unsuitable large, spheroid 34 and check-valves are advisable to be positioned at pars infrasegmentalis under tube for transfusion (referring to hypomere 1/3rd), and this is that it is very convenient because repeat pinching, need not alternately open and close its liquid inlet and outlet.In addition, owing to there is no check-valves on dropping funnel inlet, compared with anti-liquid residue formula transfusion device, the air in dropping funnel can be got in infusion bottle and make its intrinsic pressure a little rising, favourable tube for transfusion topping up, does not affect transfusion operation.Separately, because spheroid 34 can be by residual liquid input human body in tube for transfusion, therefore the volume of reservoir 44 is also unsuitable excessive.In continued access last infusion bottle on the same day, conveniently external controllable type bypass type fluid guidance port 47 is opened to (i.e. so-called can opening in advance for nurse), just can be infused and make the residual liquid Automatic-descending of dropping funnel bottom, film valve 48 and tube for transfusion epimere intracavity latter stage on the same day.In the time that conditions of patients sudden change need add drops physic liquor temporarily, can be closed conveniently (what is called can supply nurse with closing) just can make film valve 48 return to automatic liquid-stopping state.Compared with membrane type automatic liquid-stopping precision filter infusion set, its advantage is: can not only prevent that tube for transfusion epimere from generating residual liquid, and can be by defeated clean the valuable residual liquid in infusion bottle, dropping funnel bottom, film valve and transfusion lumen; Can avoid waste, can guarantee again curative effect.Even if private room patient takes bottle transfusion and slips or faint in toilet and batter down infusion bottle and do not found in time, also can effectively prevent blood accident.As shown in Figure 5,6, also can be descended the spheroid liquid outlet of row's pump to be arranged to tongue formula spheroid liquid outlet 36.Its using method is: 1. when for season in midwinter patient drip when defeated, tongue formula spheroid liquid outlet 36 can be put in to especially inner chamber middle part of spheroid 37 intracavity, can tackle and collect from the interior anger in tube for transfusion above it and steep; 2. dripped the same day in defeated latter stage, by tongue formula liquid outlet 36 retraction original positions, then lower row's pump is adjusted to perpendicular position and (refers to spheroid inlet upward, now gas is above liquid) and pinching spheroid 37, can be by defeated residual liquid clean, defeated when clean when observing residual liquid, stop pinching spheroid and can pull out pin, need not alternately open and close spheroid liquid inlet and outlet, operation is comparatively convenient.Be understood that, as shown in Figure 5, it at least comprises eight kinds of embodiments: for example, both lower row's pump and/or imitative gallbladder formula can be rinsed to a bottle eropper omission, also lower row's pump and/or controllable type liquid Lu Zaitong mechanism can be omitted, also can rinse bottle eropper and/or controllable type liquid Lu Zaitong mechanism and omit (all not separately mappings) imitating gallbladder formula, be respectively used to drip defeated dissimilar medicinal liquid or for different patients.As shown in Fig. 5,7,8 and 9, also can displace row's pump 55 with reversible pump.It is by spheroid 34, spheroid inlet, spheroid liquid outlet and be located at the endoceliac trip core 58 of ball (for proportion is less than the float of water, also can be dish or other shape, hollow, solid, soft material, hard material all can; Also be considered as the abbreviation of Manual Hydraulic switch stand) and the check-valves 53 being located on spheroid 34 liquid outlets form.First it is adjusted to perpendicular position again pinching spheroid 34 residual liquid can be forced into human body, residual liquid is defeated swims core 58 when clean and falls to automatically closing closed solid sphere liquid outlets, in case gas is pumped into human body by careless manipulation or the too quickly accident of pinching spheroid.Repeat pinching spheroid 34 quick infusion that can pressurize.As shown in figure 10, be inverted the interior anger that reversible pump makes spheroid liquid outlet upward and pinching spheroid can upwards be gone out in tube for transfusion fast and steep, be applicable to a large amount of transfusions of patient with severe symptoms in season in a midwinter defeated use for a long time.
