Description
Technical field
This utility model relates to the aseptic medical equipment for clinical transfusion purposes, especially relates to a kind of safety type disposable infusion set.
Background technology
In clinical transfusion process, usual medical personnel will look after the transfusion of patient in several ward, labor intensity is very large, usually occur that failing to observe in time infusion bottle inner liquid medicine because of medical personnel, patient or family numbers of patients has been totally lost and does not change infusion bottle in time or extract the phenomenon of infusion needle, liquid level declines too low and causes gas to enter human body causing the adverse consequencess such as aeroembolism, bring heavy mental burden to medical personnel, patient or family numbers of patients.
Summary of the invention
The purpose of this utility model is: provide a kind of safety type disposable infusion set, and the automatic plugging dropping funnel liquid outlet when transfusion nearly completes, makes infusion pipeline liquid stop flowing, prevents air from entering in patient body and refluxes with body inner blood, ensure safety.
This utility model is achieved through the following technical solutions: this transfusion device comprises protective sleeve, bottle plug puncture unit, air filter, dropping funnel, float valve, falope ring cap, transfusion catheter, flow regulator, liquid medicine filter and venoclysis needle, bottle plug puncture unit is sleeved on dropping funnel epimere, dropping funnel hypomere is built with float valve, the bottom of dropping funnel connects transfusion catheter one end, the other end of transfusion catheter connects the inlet of liquid medicine filter through flow regulator, the liquid outlet connecting intravenous infusion pin of liquid medicine filter, overall formation safety type disposable infusion set; It is characterized in that: the outside of float valve is gear-like sidewall, the top of float valve is the spherical convex surface of buffering, the bottom of float valve is provided with recess, the falope ring cap that one end is provided with diaphragm seal is embedded in the base recess of float valve, recess inwall and falope ring cap joint have air channel, and diaphragm seal flushes with float valve bottom surface and just to the infusion port of dropping funnel hypomere.
Wherein, the external diameter of described float valve is more smaller than dropping funnel hypomere internal diameter, and under the gap length guarantee normal infusion state of air channel, liquid cannot enter float valve cavity.
Wherein, described dropping funnel epimere inner joint is provided with at dropping funnel hypomere external tapping end position place and only rises bank, and float valve is active in and only rises between bank and infusion port.
Wherein, integrated injection molding dropping funnel lid and pore on described bottle plug puncture unit, install air filter in pore.
Wherein, dropping funnel epimere and dropping funnel hypomere combination after dropping funnel capacity be respectively: 6cc, 8cc, 10cc, 12cc, 14cc.
When starting to infuse, being diverted to sidewall gear-like hole slot after on the spherical buffering convex surface that liquid is first dropped in float valve flows into bottom dropping funnel, along with the rising of liquid level, float valve rises under the buoyancy of liquid, diaphragm seal departs from infusion port, realize infusion process, when infusing close to when completing, float valve declines, when contacting to diaphragm seal with infusion port, under atmospheric pressure and float valve gravity pressure along with liquid level, diaphragm seal just tightly blocks infusion port, make air not enter into infusion pipeline, thus prevent air from entering human body and the backflow of body inner blood, realize safe infusion.
This utility model structure is simple; safe and reliable; the automatic plugging infusion unit titrimeter liquid outlet when transfusion nearly completes; the medicinal liquid in infusion pipeline is made to stop flowing; thus automatically terminate transfusion; reach and prevent air from entering in patient body and the backflow of body inner blood, ensure safe infusion, this for reduce further and avoid malpractice there is very positive meaning.
