A device comprising a positive pressure chamber, a slow-release valve and a joint which are combined into a whole is arranged, the positive pressure chamber is divided into a driving cavity and a liquid storage cavity, and liquid can be filled into the liquid storage cavity in advance or is filled into the liquid storage cavity during use; by use of the inherent bubble point characteristic of a filtering medium, the bubble point numerical value of the filtering medium is regulated, a resistance which is less than or equal to the pressure of the positive pressure chamber is formed, The resistance limits that the liquid which is in a positive-pressure driving state in the liquid storage cavity can only be slightly and slowly released and filled into the joint so as to further enter into the indwelling catheter, so that the positive-pressure slow-release time of the liquid in the liquid storage cavity is greatly prolonged, the indwelling catheter connected with the liquid storage cavity is in a positive-pressure state for a long time, and thus the purpose of preventing blood from flowing back to the indwelling catheter so as to prevent formation of thrombus is achieved.
Description
Technical field
The present invention relates to technical field of medical instruments, be specifically related to a kind ofly for preventing transfusion inlying catheter blood back flow and thrombosed inlying catheter thrombosis prevention device during indwelling in blood vessel, it is a kind of device that coordinates inlying catheter to use to prevent its complication.
Background technology
Venous detaining needle as the substitute products of venoclysis needle with the security concepts of no-needle transfusion from first Application in 1958 in clinical, so far, including PICC etc., remaining needle generally uses.Venous detaining needle is mainly made up of puncture draw point and inlying catheter, prepares next infusion gain the name because of inlying catheter indwelling in human vein blood vessel.But along with a large amount of uses of remaining needle, the hiding risk of inlying catheter is also gradually appeared in the newspapers.These problems are problems of blood coagulation and the obstruction of inlying catheter, and have been found that it becomes the common adjoint problem of venous detaining needle.The experimental data of paper " can carry out the applied analysis comparative study in venous detaining needle of a good fortune joint and calparine cap " literary composition of delivering in " clinical neurosurgery magazine " the 4th the 2nd phase of volume in 2007 according to people such as Han Wei just report is pointed out, apply plugging case that the remaining needle of calparine cap tube sealing processing produces unexpectedly still up to 40%, visible indwelling tube blockage problem is serious in large-area.Based on this kind of situation, medical apparatus and instruments manufacturer also in succession develops the products such as the tube-sealing solution of calparine cap, terminal sterilization and coordinates processing, nearly ten years, Needleless barotropic joint is claimed and can be addressed the above problem, the good fortune the come joint of producing with American I CU medical company, especially CLC2000 type positive pressure connector, can be used as the anti-hemostasis-coagulation of inlying catheter in recent years and forms a representative of thrombosis or obstruction.With almost contemporaneity of above-mentioned positive pressure connector, U.S. company BD is from another angle, design inlying catheter irrigator, this device preliminary filling normal saline, when suggestion is used venous detaining needle, every 6～8 hours, inlying catheter is implemented to once flushing, in case return blood stops up inlying catheter, this mode is widely accepted.
To at present, for venous detaining needle is applied the complication causing and eliminates its application risk, derivative positive pressure connector and two kinds of main disposal methods of catheter flusher of forming.But, even so, in two kinds of disposal methods, the wherein positive pressure connector product take the good fortune the come joint of American I CU medical company as representative, comprise famous German Bei Lang company (B.BRAUN) or the positive pressure connector of U.S. company BD, neither really effectively solve problem.The use of positive pressure connector is can produce repulsion at infusion utensil and the venous detaining needle time of releasing, underbalance effect while preventing to separate, stops conduit to produce blood back, and a large amount of clinical datas confirm, separate latter 30 minutes at infusion utensil, visible blood-flow enters in inlying catheter.The experimental data of the people's such as above-mentioned Han Wei same piece of writing article also points out, the blood back number that application can carry out good fortune positive pressure connector is 6%, but with the blood back number of calparine cap tube sealing unexpectedly And this blood back is the known immediate cause that produces blood coagulation in inlying catheter, form thrombosis or obstruction of causing, these blood coagulation bolts are hidden in inlying catheter end, are hidden in we and opaque blood vessel, and naked eyes cannot directly be observed and relatively hidden.In addition, the common absolute altitude of venous transfusion is in 100cm left and right, in other words, the pressure reduction of annotating when transfusion in inlying catheter approximately reaches 10kPa, if do not processed, these blood coagulations or thrombosis are all pushed back in blood vessel as a rule, and significantly risk is, these blood coagulation bolts might not be in blood vessel size degradation, perhaps the risk that it brings and harm are just exceeding the facility that remaining needle brings.Clinical data shows, the positive pressure connector of prior art scheme, effect is limited, its benefit is confined to the time of releasing of infusion utensil, and catheter flusher rinses the technical scheme of inlying catheter, not only increased the labor intensity of medical expense and nursing, the formation risk that also faces thrombosis in 6 hours of its occupation mode interval is still failed fully assessment.
For this reason, CN103330970A discloses a kind of self-styled preventing thrombosis venous detaining needle and using method thereof, propose to sentence at vein detained needle seat the mode of cutting off and permeate and be arranged to malleation chamber and transfusing chamber, make transfusing chamber all the time in barotropic state, in case return blood, thereby stop blood coagulation and prevent thrombosis, but this technical scheme using method is complicated, be difficult to clear the air in described chamber, and must coordinate venoclysis needle to use, do not meet the occupational safety demand trend of no-needle transfusion, and there is the risk of air embolism, larger problem is, its mode with liquid infiltration is implemented malleation and is kept, after infusion lipid soln and indwelling exceed 24 hours, because the obstruction of infiltration lane, cause almost complete failure of malleation, the preventing thrombosis performance that its scheme is declared is failure thereupon.
In other words, there is no at present a kind of intrinsically safe utensil and go thoroughly effectively to solve the problem that produces blood coagulation, formation thrombosis or obstruction in above-mentioned venous detaining needle use procedure.
Summary of the invention
The problem to be solved in the present invention be to provide a kind of easy and simple to handle, meet existing transfusion standard can solve the defect relating in above-mentioned background technology, overcome the existing risk of background technology, thoroughly effectively solve the inlying catheter thrombosis prevention device that produces blood coagulation, formation thrombosis or clogging in venous detaining needle use procedure.
To achieve these goals, the present invention has adopted following technical scheme:
A kind of inlying catheter thrombosis prevention device, comprise the plemum and the joint that are combined as a whole, described plemum is endcapped, the hollow pipe that the other end is communicated with joint, described joint is the cone joint of 6: 100 taperings, or for can puncture mode being communicated with the joint of inlying catheter outer end interface, described plemum and joint are via the connection of slow release valve, described plemum is divided into actuator chamber and liquid storage cylinder.
Wherein, described slow release valve is a kind of filter medium or filter medium and carrier thereof, the filter medium of the bubble point of the pressure value that related filter medium has for a have≤plemum, it act as controls speed that liquid of liquid storage cylinder flows out so that it slowly disengages to joint.

Cardinal principle of the present invention is:
Utilize the intrinsic bubble dot characteristics of filter medium, make it form the resistance of the pressure that a have≤plemum has by adjusting the bubble point value of filter medium, the liquid of this resistance limits liquid storage cylinder under malleation driving condition only can enter inlying catheter by the slow fill nipple that discharges in trace ground then, thereby significantly extend the time of the liquid malleation slow release of liquid storage cylinder, make inlying catheter for a long time in barotropic state, reach and stop blood backflow to prevent thrombosed object in inlying catheter.
Compared with the prior art, the beneficial effect of technical solution of the present invention is:
(1) venous detaining needle is in the time ending transfusion, connect and start apparatus of the present invention at venous detaining needle end, preliminary filling or the liquid that is filled in liquid storage cylinder are subject to the power drive of actuator chamber, form malleation and break through slow release valve and enter joint, thereby the inlying catheter that enters venous detaining needle makes it keep malleation, because the existence of malleation, blood can not be back in inlying catheter, efficiently solves the problem that produces blood coagulation, formation thrombosis or obstruction in venous detaining needle use procedure.
(2) due to the use of slow release valve, it has utilized filter medium bubble dot characteristics, by adjusting filter medium bubble point, make slow release valve form a resistance, this resistance is less than or equal to the driving force that in plemum, actuator chamber produces, while making the liquid of this drive force liquid storage cylinder, just can be in only breaking through the restriction of resistance, make it slowly discharge infusion liquid and enter joint, be unlikely to again to discharge soon completely, extended the persistent period of malleation.The malleation length of holding time depends on that the liquid in liquid storage cylinder can maintain the time of transfusion, it is determined by two factors of liquid reserves of unit interval liquid output amount and liquid storage cylinder, meeting under clinical practice needs prerequisite, liquid storage amount need to be confined to 1～2mL or when slightly larger, as after this liquid storage amount determined, unit of adjustment's time output is exactly key factor, exports more micro-ly, and malleation is held time just longer in principle.Apparatus of the present invention, by the relation between the size of filter medium bubble point value and the size of actuator chamber power is set, can be controlled malleation and hold time at 1 hour to 100 hours, are preferably between 24 hours to 96 hours.After reaching and maintaining malleation for a long time, just can avoid for a long time blood back to enter in inlying catheter, make inlying catheter there will not be the problem such as blood coagulation, thrombosis or obstruction, use apparatus of the present invention, can abandon catheter flusher and positive pressure connector completely, not only reduce medical expense but also reduce nursing labor intensity.
(3) owing to applying the bubble dot characteristics of filter medium, the actual filtration size of this characteristic and filter medium is irrelevant, therefore can guarantee under the prerequisite of certain concrete bubble point of filter medium, length while maintaining malleation as required, and suitably adjust the actual filtration area of filter medium, can effectively delay filter medium the time that microgranule stops up occurs because of long-time micro-slow release infusion, prevent from occurring too early stopping up and cause malleation to lose efficacy, solving the malleation inefficacy defect existing in scheme as disclosed in CN103330970A in above-mentioned background technology.
(4) because apparatus of the present invention are the independent utensils that are free on venous detaining needle, therefore it has evaded the functional limitation that certain concrete pattern venous detaining needle may exist, and there is general applicability widely, can carry out supportingly with the venous detaining needle of any pattern or the trade mark, there is the ability of topic that whole venous detaining needle is sent one's regards to of solution.
