Abstract
The utility model discloses a dual-chamber dropping funnel transfusion system, which comprises a bottle puncture needle, an air filter, a dropping funnel, a hose, a Y-type three-way pipe, a transfusion hose and a vein transfusion needle, wherein, the vein transfusion needle is connected with the output end of the dropping funnel through the transfusion hose; the Y-type three-way pipe and the hose; the dropping funnel comprises 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 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.

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 transfusion device.
Background technology
Existing transfusion device (see figure 1) comprises needle for inserting bottle 1, air filter 2, dropping funnel 3, flexible pipe 4, Y-type three way type pipe 6, tube for transfusion 7, reaches venoclysis needle 8 etc., be with actuator 5 on the flexible pipe 4, venoclysis needle 8 links to each other with the outfan of dropping funnel 3 by tube for transfusion 7, Y-type three way type pipe 6 and flexible pipe 4, and Y-type three way type pipe 6 can dosing midway in infusion process as injection member.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, and dropping funnel kettle 31 is generally expected to make with injection moulding or plastic uptake and expressing technique by PVC, 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 medicine liquid droplets; Filter 33 is positioned at the bottom of dropping funnel kettle, and it is blocked in the impurity in the medicinal liquid on the filter 33 and can cleans medicinal liquid.But, impurity in the medicinal liquid can be in infusion process blocking filter 33, influence transfusion speed even blocking-up medical filtration, 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 infusion process.But because the construction features of existing dropping funnel 3, this method but makes impurity flow into human body with medicinal liquid easily, influences injection 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 transfusion device, and it can be guaranteed quality of liquid medicine and make finishing smoothly of infusion process.
The purpose of this utility model is achieved by following technical scheme, a kind of double-cavity drop funnel transfusion device, comprise needle for inserting bottle, air filter, dropping funnel, flexible pipe, the Y-type three way type pipe, tube for transfusion, and venoclysis needle etc., venoclysis needle passes through tube for transfusion, Y-type three way type pipe and flexible pipe link to each other with the outfan of dropping funnel, dropping funnel comprises the dropping funnel kettle, be 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 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 transfusion device, in the tool, described dropper is a funnel-form, it is to connect by hot pressing that tool is connected with the inner wall sealing of dropping funnel kettle.
Above-mentioned double-cavity drop funnel transfusion device, wherein, described filter is a screen pack.
Above-mentioned double-cavity drop funnel transfusion device, in the tool, described flexible pipe is provided with actuator.
Owing to adopted the technical solution of the utility model, in infusion 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 impurity that is 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 medicinal liquid cleanliness factor, make impurity can not flow into human body.
Description of drawings
