Abstract
The invention discloses a double-cavity chamber transfusion set, which includes a spike, a soft cannula, a chamber, a transfusion tube and a vena transfusion needle, the vena transfusion needle is connected with the output end of the chamber by the transfusion tube, the chamber includes a chamber bottle, a dropper arranged in the chamber bottle and a filter, the dropper is positioned at the middle part of the chamber bottle and is closely connected with the inner wall of the chamber bottle and partitions the inner cavity of the chamber bottle into an upper cavity and a lower cavity serving as a press cavity, the filter is arranged in the upper cavity of the chamber bottle. Because of the adoption of the technique proposal of the invention, the peripheral wall of the lower cavity of the chamber bottle can be pinched come-and-go during the blood transfusion process for ensuring that the filter net will not be blocked and the traffic will not be affected, then the pressure in the lower cavity of the chamber bottle can be pushed upward, blood coagulation matters and impurities piled on the filter will be scattered in the upper cavity of the chamber bottle, so the filter is unblocked, thus the dripping amount and blood cleanness of the dropper can be ensured, and the blood coagulation matters and impurities will not flow into the human body.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, relate 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 objective of the invention is to overcome above-mentioned the deficiencies in the prior art, provide on a kind of double-cavity drop funnel blood transfusion device, it can be guaranteed blood quality and make finishing smoothly of blood transfusion process.
The objective of the invention is to be 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 technical scheme of the present invention, 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;
Fig. 2 is the structural representation of double-cavity drop funnel blood transfusion device of the present invention.
The specific embodiment
See also Fig. 2, double-cavity drop funnel blood transfusion device of the present invention comprises needle for inserting bottle 1, flexible pipe 2, dropping funnel 3, blood transfusion tube 4, actuator 5 and venoclysis needle 6, venoclysis needle 6 links to each other with the outfan of dropping funnel 3 by blood transfusion tube 4, and the actuator 5 that is with on this blood transfusion tube 4 can be used as the speed of regulating blood transfusion or cuts out blood transfusion tube 4.
Dropping funnel 3 comprises dropping funnel kettle 31, dropper 32 and filter 33, wherein, dropper 32 is positioned at the middle part of dropping funnel kettle 31 and is connected with the inner wall sealing of dropping funnel kettle 31 and dropping funnel kettle 31 inner chambers are divided into epicoele 311 and cavity of resorption 312, cavity of resorption 312 is as extrusion chamber, the epicoele 311 of dropping funnel kettle 31 is 0.9～1.2:1 with the length ratio of cavity of resorption 312, dropper 32 preferably is positioned at the length center of dropping funnel kettle 31, and this dropper 32 is a funnel-form, and it is to connect by hot pressing that its inner wall sealing with dropping funnel kettle 31 is connected.
Described filter 33 is arranged in the epicoele 311 of dropping funnel kettle 31, and it can be filtering screen or web plate.
Owing to adopted technical scheme of the present invention, in the blood transfusion process, for guaranteeing that dropper 32 oozes 20 liquid of bleeding and is about the flow of 1ml, can pinch the perisporium of dropping funnel kettle cavity of resorption 312 back and forth, the pressure of dropping funnel kettle cavity of resorption 312 is upwards pushed away, the coagulation matters and the impurity that are deposited on the filter 33 will be broken up in the epicoele 311 of dropping funnel kettle, make filter 33 unimpeded, thereby guarantee 32 amounts of dropper and blood cleanliness factor, make coagulation matters and impurity can not flow into human body.
Above embodiment is only for the usefulness that the present invention is described, but not limitation of the present invention, person skilled in the relevant technique, under the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
