Abstract
The utility model discloses a dual-chamber dropping funnel blood transfusion device, which comprises a bottle puncture needle, a hose, a dropping funnel, a blood transfusion tube and a vein transfusion needle, wherein, the vein transfusion needle is connected with the output end of the dropping funnel through the blood transfusion tube; the dropping funnel contains a dropping funnel kettle, a dropper arranged in the dropping funnel kettle and a filter with the dropper arranged at the middle part of the dropping funnel kettle and hermetically connected with the inner wall of it and separating the intracavity of the dropping funnel kettle into a upper cavity and an lower cavity as an extrusion cavity, and the filer disposed in the upper cavity of the dropping funnel kettle. Through adoption of the technical proposal of the utility model, during blood transfusion, user, in order to ensure non-blockage of filter gauze resulting in influence on flow rate, can repeatedly pinch the outerwall of the lower cavity of the dropping funnel kettle to push upward the pressure therein so as to scatter the cruor and impurity accumulated at the filter in the upper cavity of the dropping funnel kettle and make the filter smooth, thereby guaranteeing dropper dropping rate and blood purifying degree and preventing cruor and impurity from flowing into human body.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of double-cavity drop funnel blood transfusion device.
Background technology
Existing blood exchange transfusion set's (see figure 1) comprises needle for inserting bottle 1, flexible pipe 2, dropping funnel 3, blood transfusion tube 4, actuator 5 and venoclysis needle 6 etc., venoclysis needle 6 links to each other with the outfan of dropping funnel 3 by blood transfusion tube 4, dropping funnel 3 is made up of dropping funnel kettle 31, the dropper 32 and the filters 33 that are arranged in the dropping funnel kettle 31, dropping funnel kettle 31 is generally made with injection moulding or plastic uptake and expressing technique by PVC material, has certain elasticity; Dropper 32 is positioned at the upper end of dropping funnel kettle 31, and the flow of dropper 32 is 20 of per 1 milliliter of droplet of blood; Filter 33 is positioned at the bottom of dropping funnel kettle, and it is blocked in the impurity in the blood on the filter 33 and the energy blood clean.But, coagulation matters in the blood and impurity can be in the blood transfusion process blocking filter 33, influence transfusion speed even occlude blood and filter, the maneuver of taking usually in clinical is to pinch the perisporium of dropping funnel kettle 31 back and forth, to inflation in the dropping funnel kettle 31 its pressure is increased, to guarantee finishing smoothly of the process of transfusing blood.But because the construction features of existing dropping funnel 3, this method but makes coagulation matters and impurity flow into human body with blood easily, influence blood transfusion quality.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides on a kind of double-cavity drop funnel blood transfusion device, and it can be guaranteed blood quality and make finishing smoothly of blood transfusion process.
The purpose of this utility model is achieved by following technical scheme, a kind of double-cavity drop funnel blood transfusion device, comprise needle for inserting bottle, flexible pipe, dropping funnel, blood transfusion tube and venoclysis needle, venoclysis needle links to each other with the outfan of dropping funnel by blood transfusion tube, dropping funnel comprises the dropping funnel kettle, is arranged on dropper and filter in the dropping funnel kettle, described dropper is positioned at the middle part of dropping funnel kettle and is connected with the inner wall sealing of dropping funnel kettle and dropping funnel kettle inner chamber is divided into epicoele and as the cavity of resorption of extrusion chamber, described filter is arranged in the epicoele of dropping funnel kettle.
Above-mentioned double-cavity drop funnel blood transfusion device, wherein, the epicoele of described dropping funnel kettle and the length ratio of cavity of resorption are 0.9～1.2: 1.
Above-mentioned double-cavity drop funnel blood transfusion device, wherein, described dropper is a funnel-form, it is to connect by hot pressing that its inner wall sealing with the dropping funnel kettle is connected.
Above-mentioned double-cavity drop funnel blood transfusion device, wherein, described filter is filtering screen or web plate.
Above-mentioned double-cavity drop funnel blood transfusion device, wherein, described venoclysis needle is provided with actuator with the blood transfusion tube that the outfan of dropping funnel links to each other.
Owing to adopted the technical solution of the utility model, in the blood transfusion process, influence flow for guaranteeing that filter screen does not get clogged, can pinch the perisporium of dropping funnel kettle cavity of resorption back and forth, the pressure of dropping funnel kettle cavity of resorption is upwards pushed away, the coagulation matters and the impurity that are deposited on the filter will be broken up by intracavity on the dropping funnel kettle, make filter unimpeded, thereby guarantee dropper amount of dripping and blood cleanliness factor, make coagulation matters and impurity can not flow into human body.
Description of drawings
Fig. 1 is the blood exchange transfusion set's of prior art a structural representation;
