Abstract
The utility model discloses a transfusion filter with a liquid checking membrane, in particular relates to a filter capable of checking liquid automatically and preventing the backflow of the blood. The transfusion filter with the liquid checking membrane aims at providing a simple structure, low cost and convenient use transfusion filter with the liquid checking membrane. The liquid checking membrane is arranged inside the filter and the liquid checking membrane separates the filter into two separated cavities from the liquid inlet end to the liquid outlet end so that a flow from the liquid inlet end to the liquid outlet end must go through the liquid checking membrane. The transfusion filter with the liquid checking membrane is widely used in clinical transfusion and has the advantages of being convenient in use, safety and healthy and the like.
Description
Technical field
This utility model relates to a kind of medical apparatus, and the medicinal liquid in especially a kind of transfusion patient transfusion bag or the bottle is used the light time, and automatic liquid-stopping prevents the filter of blood backflow.
Background technology
Transfusion device is widely used in clinical transfusion, mainly formed by needle for inserting bottle, infusion pipeline, dropping funnel, filter, flow regulator, because frequency of utilization is high, present medical space often all is that the many medical personnel of patient are few, and a lot of patients are when the medical liquid container herb liquid is lost, and medical personnel can not in time pull out transfusion needle to patient, blood tends to be back in the tube for transfusion, this patient to much being in a bad way increases the weight of the state of an illness, and also can work the mischief, and also easily causes conflict between doctors and patients.Also someone has designed a kind of transfusion device of liquid medicine filter of blood-backflow preventing now, such as CN201120320214.9, name is called in " a kind of transfusion device with blood backflow prevention liquid medicine filter " and discloses a kind of liquid medicine filter, is provided with medicinal liquid baffle plate, bearing and baffle plate base in its inside.But there are the defectives such as processed complex, cost is high, use is inconvenient in the filter for transfusion of this structure.And the industry of medical apparatus middle filtrator only reaches several hundred million yuan Chinese every year, if this disposable consumable goods effectively solves the problem that exists, any one company that has this scheme will obtain tremendous development.
Summary of the invention
As the supplier who is well versed in the industry the market demand, Voigt medical apparatus and instruments company limited is very clear to the problem of this existence, set up R﹠D force, dropped into a huge sum of money of millions of units, go through nearly research of technique more than 2 years, comprise bending over one's desk working and a large amount of test, option screenings day and night, and a large amount of customer survey has obtained the technical solution of the utility model finally.
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, filter for transfusion that band that cost is low, easy to use ends liquid film is provided.
Band of the present utility model ends the filter for transfusion of liquid film, is provided with only liquid film in the filter, and the described liquid film that ends is separated into two cavitys that separate to filter liquid feeding end to liquid outlet, namely the medicinal liquid of described liquid feeding end flow to liquid outlet must be through ending liquid film.
As preferably, described filter is provided with air-vent, and described air-vent seals by ventilated membrane, makes the medicinal liquid in the cavity of filter not contaminated.
As preferably, describedly end liquid film and filter membrane is arranged at respectively in the filter cavity, both link into an integrated entity by the wall of filter.
As preferably, described air-vent is arranged at the liquid feeding end of filter and ends on the cavity between the liquid film.
As preferably, the described liquid film that ends fixedly is one with filter membrane, and described only liquid film and filter membrane can certainly be that alternate manner is combined into one by welding or bonding mode is combined into one the two; This both are combined into one and have the more easily characteristics of assembling, and cost can further reduce.Certainly, describedly end liquid film and filter membrane can not be combined into one yet, Independent places on the cavity of filter, and described the setting can be bonding or welding manner is connected with the filter cavity.
The band of the present utility model filter that ends liquid film has the characteristics such as health easy to use, safe in sum.
Description of drawings
Fig. 1 is the structural representation of embodiment 1 of the present utility model.
Fig. 2 is the structural representation of another embodiment of this utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing
Embodiment 1:
In Fig. 1, the filter that band of the present utility model ends liquid film comprises upper end cover 2 and bottom end cover 7, be provided with the diaphragm that only liquid film 3 and filter membrane 4 are combined into one in the two end cap junction, filter is the medical grade rubber-plastics material, and upper end cover 2, diaphragm, bottom end cover 7 link into an integrated entity by ultrasonic bonding; Be provided with air-vent 5 at upper end cover 2, air-vent 5 is provided with ventilated membrane 6, and the medicinal liquid of described liquid feeding end 8 flows to liquid outlet 1 must be through ending liquid film 3.
Among Fig. 2, be that with the difference of Fig. 1 only liquid film 3 is connected by the filter cavity with filter membrane 4, i.e. both not directly contacts.
Claims (6)
