Description

The pressurization intravenous transfusion device

Technical field

This utility model relates to a kind of medical apparatus and instruments, is a kind of pressurization intravenous transfusion device.

Background technology

Be used for clinical intravenous transfusion device at present, mostly will dispose independent air inlet pipe in addition and can use.There is following shortcoming in the intravenous transfusion device of this kind form in the middle of reality is used: one, can't pressurize in the liquid container, cause the dropping speed range of accommodation of liquid narrow, if need the accelerating liquid dropping speed then can't realize; Two, if in infusion process again when adding medicine in the liquid, can only puncture once more on the serum cap of liquid container mouth, it is more loaded down with trivial details so not only to operate, and is easy to pollute; Three, do not have filter at tube for transfusion and stilligout seam, when the direct vein of its seam pushes away medicine, then can't filter pushing away medicine for needing in the infusion process.The intravenous transfusion device of this kind form has brought inconvenience to every aspect clinically thus.

Summary of the invention

The purpose of this utility model is for overcoming above-mentioned technical deficiency part, a kind of pressurization intravenous transfusion device is provided, and it can integrated realization air inlet, transfusion, pressurization, dosing and filtration work.

The purpose of this utility model is achieved in that the pressurization intravenous transfusion device, comprise combination syringe needle, stilligout, actuator, joint, filter, tube for transfusion and scalp acupuncture, transfusion needle joins in the upper end of stilligout and the combination syringe needle, joint joins by tube for transfusion and scalp acupuncture, match with the inner joint that filter is housed in the lower end of stilligout, actuator is installed on the stilligout.

Advantage of the present utility model: one, reasonable in design, its adopts, and combination syringe needle is integrated finishes air inlet, transfusion, pressurization, dosing work, operate quite simple, so alleviated medical personnel's loaded down with trivial details work; While is configuration filter in the tube for transfusion joint again, has avoided pushing away medicine process Chinese medicine impurity and has entered human body; Two, simple in structure, easy making, be convenient to promote.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model.

The specific embodiment

The pressurization intravenous transfusion device, comprise combination syringe needle 5, stilligout 7, actuator 6, joint 8, filter 9, tube for transfusion 10 and scalp acupuncture 11, transfusion needle 2 joins in the upper end of stilligout 7 and the combination syringe needle 5, joint 8 joins by tube for transfusion 10 and scalp acupuncture 11, match with the inner joint 8 that filter 9 is housed in the lower end of stilligout 7, actuator 6 is installed on the stilligout 7.Combination syringe needle 5 is made up of transfusion needle 2, Needle with pressure-increasing means 1, three-way valve 4 and filter 3, the top of Needle with pressure-increasing means 1 is on transfusion needle 2 vertical tops, the join other end of three-way valve 4 of one end of the bottom of Needle with pressure-increasing means 1 and three-way valve 4 has air inlet 13 and inlet 12 respectively, and filter 3 is housed in the air inlet 13.During making, process to assemble behind the various parts by above-mentioned requirements and get final product.During use, combination syringe needle 5 of the present utility model is punctured in liquid container, turn three-way valve 4 makes in its air inlet 13 and the container and communicates, and 12 of inlets are closed simultaneously, and can infuse in the usual way this moment.When need adding medicinal liquid, but turn three-way valve 4 make in its inlet 12 and the container and communicate, 13 of air inlets are closed simultaneously, the medicinal liquid of required adding is then by in the inlet 12 adding containers.After dosing finishes again turn three-way valve 4 make it advance fluid port 12 and air inlet 13 is closed simultaneously, to prevent its leakage.Open the air inlet 13 of three-way valve 4 when dropping speed to be observed slows down again, make its interior atmospheric pressure state of protection in the air admission container.If when needing to accelerate dropping speed, then exert pressure in container by the air inlet 13 of three-way valve 4 with the empty needle pipe, the turn three-way valve 4 then, and inlet 12 and air inlet 13 are closed simultaneously.Carry out to keep the pressure in the container to press thus repeatedly, accelerate dropping speed.If need when the infusion process medium-sized vein injects medicine, can close actuator 6 earlier, joint 8 is unpluged from stilligout 7 lower ends, the syringe port that medicine will be housed again inserts joint 8 interior pushers and goes into medicine, and this moment, medicine then was pushed into intravenous by joint 8, tube for transfusion 10, the scalp acupuncture 11 that filter 9 is housed.Stilligout 7 and actuator 6 are known technology.
