Description
Technical field
The present invention relates to a kind of defecator.
Background technology
Clinical transfusion is an important clinical subject of modern medicine.It includes water and the balance of electrolyte is disorderly
Disorderly, the important content such as acid base imbalance and threpsology, these Balance disorders occur together in multiple pathological processes.
The direct vein of the different state of an illness be can also be for while nursing one's health these Balance disorders by rational transfusion
Inject corresponding medicine, rapidly and efficiently alleviate and treat the purpose of disease to reach.
With the continuous improvement of medical needs and pharmaceutical technology, therapeutic transfusion kind also enters successively
Clinical.Therefore, transfusion is paid attention to by clinicians at different levels and is employed, and the consumption of infusion preparation is also fast
Speed increases, and current China year, consumption reached more than 3 bottles per capita.In order to adapt to the demand of medical treatment, big transfusion
Manufacturing industry lifting for improve product quality and safe medication, preparation packaging level while increasing yield
And it is subject to pharmacy paying much attention in the industry.And the hard plastic glue bottle emerging in the recent period and non-PVC-soft plastic bag
Packaging large infusion production line, brings one new trend to big transfusion commercial production, clinical practice is also more
Safe and reliable.But also occur in that some new problems simultaneously.To transfusion package state of development and emphasis is to soft
Bag packing technique is reviewed for inquiring into.
Because medicinal liquid is directly entered blood, moment (<1 minute) just can be distributed whole body, venous transfusion exists
It is highly important base therapy means in domestic clinical treatment.Chinese Pharmacological Society's drug-induced disease is specially
The data display that industry committee provides：The domestic inpatient more than 70% has carried out infusion.
" existing infusion mode mostly is carrier transfusion, and clinically carrier transfusion person is more than 90%；Carrier is defeated
Liquid leads to thermal source and particulate matter superposition, easily increases infusion safety risk." particulate matter exceeded and
Endotoxin increase is one of main cause that transfusion occurs untoward reaction.Particulate matter enters human capillary vessel
Multiple disease harm that blocking causes are huge.
Particulate matter all may be had from producing to be mixed into clinical links, such as pharmaceutical production link
Quality control is strict, packaging material, operation link, supporting apparatus, environment are brought into.
《Chinese Pharmacopoeia》The particulate matter of right >=10 μm and >=25 μm defines, but not yet relates to
And 2～10 μm of microgranule.And once 2～10 μm particulate matter enter human body, discharge when
Between even more than 20 years.
At present, a lot of children's hospitals and Grade A hospital at home, a kind of precision transfusion filter extremely sells well,
The major function of this product is to filter out particulate matter and visible foreign matters of interior more than 2 μm of transfusion etc.
Impurity, but such product is higher in price, brings burden to patient.
Therefore should just improve infusion products particulate matter control standard manufacturing link, for this this public affairs
A Novel filter device is studied by department, and this device can be matched in large transfusion bottle body, soft bag bottle, also can be
Manufacture link to be directly connected on transfusion bottle/bag interface.
Content of the invention
The technical problem to be solved in the present invention is to overcome prior art fluid delivery apparatus easily defeated to human body
Enter microgranule, and the defect of filtration high cost, a kind of defecator is provided.
The present invention is to solve above-mentioned technical problem by following technical proposals：
A kind of defecator, its feature is, it includes a housing, is provided with filter membrane in described housing,
Feed pathway, lead to the filtration channel of described filter membrane, lead to described filtration channel and described feed liquor respectively
The opening that road communicates, wherein, is slidably equipped with a piston in described feed pathway, described piston be used for closing and
Open described opening.
Piston slides in feed pathway, and when piston closing opening, the liquid in feed pathway will not
Flow out, thus effectively preventing liquid from producing impact to filter membrane, it is to avoid filter membrane is breakdown.And when use
When, open opening by making piston, now, liquid flows out from feed pathway, flows into through opening
Filter passage, and filtered by filter membrane.
It is preferred that described piston is connected in a connecting rod, in described housing, it is provided with slideway, described company
Extension bar is slidedly arranged in described slideway.Piston can easily be moved by connecting rod.
It is preferred that described piston and described connecting rod are detachably connectable.When deployed, pull connecting rod
Thus arrive the end of feed pathway with piston, now further pull on down, connecting rod will be subject to piston
Power separates, and realizes coming off of connecting rod.
It is preferred that described defecator also includes a lid, described lid is arranged on outside described housing, and
Described lid is connected with described connecting rod.
It is preferred that described connecting rod includes a boss, described boss is connected with described lid, and described convex
Screw thread is provided with platform, the end of described slideway is also equipped with screw thread.
When not using, boss is threadeded with slideway, realizes fixing, prevents the movement of connecting rod.When making
Used time, by rotating lid, so that boss abjection slideway, now just can pull connecting rod.
It is preferred that being additionally provided with a liquid outlet channel in described housing, described filtration channel and described go out liquid lead to
Road is located at the both sides of described filter membrane respectively.
It is preferred that being provided with an accommodating chamber in described housing, described liquid outlet channel is connected with described accommodating chamber.
It is preferred that described housing include lid and lower cover, described filter membrane be located in described upper lid and described
Between lower cover.
It is preferred that being additionally provided with an inner sleeve in described housing, described liquid outlet channel is formed at described inner sleeve
Between the inwall of outer wall and described upper lid.
It is preferred that being provided with support base between described inner sleeve and described upper lid, described support base is attached at institute
State filter membrane.Support base can support filter membrane, and preventing is infused crushes.
In the present invention, above-mentioned optimum condition on the basis of meeting common sense in the field can combination in any, obtain final product
Each preferred embodiment of the present invention.
The positive effect of the present invention is：Microgranule can be filtered by filter membrane, in transfusion of infusing out
Just complete when bottle or transfusion bag to filter.Can directly avoid because transfusion is insoluble in manufacturing link appearance greatly
Microgranule, by being controlled in the starting stage using, directly reduces patient and bears, be also accompanied by expanding defeated
Liquid prospect for sales.
