Abstract
The utility model discloses a novel self-closing liquid retention infusion apparatus and relates to the technical field of medical appliances. The novel self-closing liquid retention infusion apparatus comprises a puncture needle (1), a drip tube (2), a liquid stop valve (3), a drip funnel (4), an isolation paper film (5), a catheter (6), a flow adjuster (7), a filter (8) and an injection needle (9), wherein a projected tube opening in the upper end of the liquid stop valve (3) is connected with the drip tube (2); the lower end of the liquid stop valve (3) is connected with the drip funnel (4); the isolation paper film (5) is arranged in the middle of the liquid stop valve (3); the flow adjuster (7) is arranged in the middle of the catheter (6); the filter (8) is arranged at the end part of the catheter (6) and connected with the injection needle (9); and the liquid stop valve (3) is a round device. After liquid medicine is dripped off, a liquid medicine outlet of the drip funnel is automatically closed, and the infusion operation is automatically stopped, so that the liquid medicine is retained in a hose, air cannot enter the hose under the action of the isolation paper film, and venous blood does not flow back for a long time. Therefore, the novel self-closing liquid retention infusion apparatus is convenient to use, safe and reliable.
Description
Technical field:
This utility model relates to technical field of medical instruments, is specifically related to a kind of Novel self-closed formula and protects the liquid transfusion device.
Background technology:
Present medical disposable infusion set for transfusion, when transfusion such as medicinal liquid be totally lost after blood can produce refluence, when changing bottle not aerofluxus dangerous, but drain gas very trouble.Some transfusion device is equipped with the self-closing valve of all styles of at dropping funnel mouth place, although can protect liquid by autoshutdown after medicinal liquid is totally lost, change bottle and open valve difficulty, troublesome poeration.
The utility model content:
The purpose of this utility model provides a kind of Novel self-closed formula and protects the liquid transfusion device, dropping funnel medicine liquid outlet self-closed after medicinal liquid drips off, transfusion stops automatically, keep medicinal liquid in the flexible pipe like this, and the release paper film makes air can't enter in the flexible pipe, the venous blood long period can not flow backwards, and is easy to use, safe and reliable.
In order to solve the existing problem of background technology, this utility model is by the following technical solutions: it comprises puncture needle 1, dropper 2, ends liquid valve 3, dropping funnel 4, release paper film 5, conduit 6, flow regulator 7, filter 8 and entry needle 9; End the liquid valve 3 upper ends one outstanding mouth of pipe and be connected with dropper 2, the lower end is connected with dropping funnel 4, and the middle part arranges release paper film 5, and flow regulator 7 is arranged on the middle part of conduit 6, and filter 8 is arranged on conduit 6 ends and links to each other with entry needle 9.
Described only liquid valve 3 is circular device.
Described release paper film 5 is vacuum filter.
Described release paper film will end liquid valve 3 and be divided into the space, front and back, medicinal liquid flows into front space by the upper port stopping means, after completely having certain pressure, the medicinal liquid accumulation of front space advances rear space by the release paper membrane permeation again, rear space lower end one outstanding pipe links to each other with dropping funnel, and rear space lower end pipe liquid inlet is higher than the floor level 0.6～0.8mm that only opens liquid valve middle part front space.
This utility model is dropping funnel medicine liquid outlet self-closed after medicinal liquid drips off, and transfusion stops automatically, keep medicinal liquid in the flexible pipe like this, and the release paper film can't enter in the flexible pipe air, and the venous blood long period can not flow backwards, and is easy to use, safe and reliable.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
With reference to Fig. 1, this implementation by the following technical solutions: it comprises puncture needle 1, dropper 2, ends liquid valve 3, dropping funnel 4, release paper film 5, conduit 6, flow regulator 7, filter 8 and entry needle 9; End the liquid valve 3 upper ends one outstanding mouth of pipe and be connected with dropper 2, the lower end is connected with dropping funnel 4, and the middle part arranges release paper film 5, and flow regulator 7 is arranged on the middle part of conduit 6, and filter 8 is arranged on conduit 6 ends and links to each other with entry needle 9.
Described only liquid valve 3 is circular device.
Described release paper film 5 is vacuum filter.
The release paper film of this implementation will end liquid valve 3 and be divided into the space, front and back, medicinal liquid flows into front space by the upper port stopping means, after completely having certain pressure, the medicinal liquid accumulation of front space advances rear space by the release paper membrane permeation again, rear space lower end one outstanding pipe links to each other with dropping funnel, and rear space lower end pipe liquid inlet is higher than the floor level 0.6～0.8mm that only opens liquid valve middle part front space.Be lower than the liquid inlet of rear space in front space residual liquor level when medicinal liquid, transfusion stops automatically, keep medicinal liquid in the flexible pipe like this, and the release paper film can't enter in the flexible pipe air, and the venous blood long period can not flow backwards.
This implementation is dropping funnel medicine liquid outlet self-closed after medicinal liquid drips off, and transfusion stops automatically, keep medicinal liquid in the flexible pipe like this, and the release paper film can't enter in the flexible pipe air, and the venous blood long period can not flow backwards, and is easy to use, safe and reliable.
