Abstract
The invention relates to a disposable safe transfusion device, which can effectively solves the problem that in current transfusion devices, the blood flows backward or air enters into the blood vessel. The technical scheme solved is that the disposable safe transfusion device comprises a dropping hopper and short catheters. A bottle plug puncture set is arranged at one end of a first short catheter. The bottle plug puncture set is connected with an air inlet communicated with the bottle plug puncture set. An air filter is arranged at one end of the air inlet. The other end of the first short catheter is connected with the dropping hopper through a dropping tube. The other end of the dropping hopper is connected with an anti-reverse flow device through a pipeline. The anti-reverse flow device consists of a shell and a check valve in the shell. The other end of the anti-reverse flow device is connected with a liquid medicine filter through a pipeline which is provided with a flow adjustor. The liquid medicine filter is provided with an injection piece. A transfusion needle is installed at the front end of the injection piece. The disposable safe transfusion device provided by the invention has a unique structure, and is convenient to use, safe and effective and innovative to transfusion apparatus.
Description
One, technical field
The present invention relates to armarium, particularly a kind of disposable transfusion device safe in utilization.
Two, background technology
Transfusion device is to use very a kind of widely medical apparatus and instruments clinically; Used transfusion device is not with anti-backflow device on the market now; After medicinal liquid is totally lost; Backflow of blood or gas intravasation taking place easily cause phenomenons such as gas blocks up, bring life danger to patient, is the basic assurance of dealing with problems to this apparatus innovation therefore.
Three, summary of the invention
To above-mentioned situation, for overcoming the defective of prior art, the present invention's purpose just provides a kind of disposable transfusion device safe in utilization, can effectively solve the problem that existing transfusion device backflow of blood or gas intravasation phenomenon take place.
The technical scheme of its solution is, comprises dropping funnel and tubulature, and first tubulature, one end has bottle plug puncture unit; Be connected to the air inlet that is communicated with bottle plug puncture unit on the bottle plug puncture unit, air inlet one end has air filter, and the other end of first tubulature links to each other with dropping funnel through dropper; The other end of dropping funnel links to each other with anti-backflow device through second tubulature; Anti-backflow device is made up of housing and the intravital check valve of shell, and the other end of anti-backflow device links to each other with liquid medicine filter by the road, and flow regulator is arranged on the pipeline; Injection member is housed on the liquid medicine filter, and the injection member front end is equipped with transfusion needle.
Structure of the present invention is unique, easy to use, safe and effective, is the innovation of infusion set.
Four, description of drawings
Fig. 1 looks connection layout for the master of each parts of the present invention.
Five, the specific embodiment
Do further explain below in conjunction with the accompanying drawing specific embodiments of the invention.
Provided by Fig. 1, the present invention includes dropping funnel and tubulature, first tubulature, 5 one ends have bottle plug puncture unit 2; Be connected to the air inlet 4 that is communicated with bottle plug puncture unit 2 on the bottle plug puncture unit 2, air inlet 4 one ends have the other end of air filter 3, the first tubulatures 5 to link to each other with dropping funnel 7 through dropper 6; The other end of dropping funnel 7 links to each other with anti-backflow device through second tubulature 8; Anti-backflow device is made up of the check valves 15 in housing 14 and the housing 14, and the other end of anti-backflow device 9 links to each other with liquid medicine filter 11 by the road, and flow regulator 10 is arranged on the pipeline 9; Injection member 12 is housed on the liquid medicine filter 11, and injection member 12 front ends are equipped with transfusion needle 13.
In order to guarantee result of use, said check valve 15 is connected between second tubulature 8 and the pipeline 9 through housing 14, and check valve 15 is processed for medical grade silicone.
The said bottle plug puncture unit 2 outer bottle plug puncture unit protective sleeves 1 that are set with improve the safety when using.
During working condition of the present invention, when giving patient infusion, medicinal liquid is opened at the following check valve 15 of action of gravity; Medicinal liquid flows in the patient's blood vessel continuously, and when medicinal liquid is about to the liquid of being totally lost, the medicinal liquid liquid level is lower than the moment of check valve 15; Check valve 15 is closed immediately, and medicinal liquid just stops in blood vessel, to flow to, and check valve 15 is to be still in the pipeline 9 because of no pressure down to residual medicinal liquid between the puncture vein; And then the air of transfusion device outside just can not pass through pipeline 9 intravasations, and the human pressure imposes opposite effect power to the medicinal liquid of 9 li of transfusion device pipelines at this moment, when check valve 15 receives this active force; Because the closing structure of check valve 15; Pressure can make the tighter of check valve 15 closures, has guaranteed that medicinal liquid can not oppositely pass through check valve 15, the phenomenon that blood can not flow backwards; Guaranteed that liquid or gas can only flow to the opposing party by a side, have stopped the phenomenon of liquid countercurrent or gas intravasation.
The present invention has changed the structure of transfusion device in the past, and manufacturing process is simple, and cost is lower, is the innovation on the transfusion device.
