Description
Technical field:
This utility model relates to a kind of disposable medical apparatus, the specifically self-enclosed automatic liquid-stopping transfusion apparatus of single use.
Background technology:
It is known that China starts to promote the use of common disposable infusion set, the most history of more than 30 year from the 1980s, to preventing cross infection from serving positive role in clinical transfusion；But, common disposable infusion set there is also certain weak point: when transfusion completes or transfusion group replaces, and air is easily accessible in infusion tube, if processing not in time, air input human body will be on the healthy generation impact of patient；Also increase the weight of the nursery work intensity of medical worker simultaneously, easily cause doctor-patient dispute；Therefore it is intended that there is the best safer product, make numerous medical workers and patient relieved, safety；In order to solve above-mentioned technical problem, prior art such as proposes some technical schemes such as:
China Patent No. discloses a kind of safe transfusion system, this transfusion device venous transfusion in medicine and hygiene fields for " CN200810048699 "；This transfusion device is made up of tube for transfusion, funnel and syringe needle, tube for transfusion is connected with funnel and syringe needle respectively, the plastic foam ball float during wherein release mechanism includes funnel, when the liquid stream in funnel is complete, the liquid outlet of its lower portion will be blocked by ball float, reaches the purpose of safe handling.
China Patent No. " 200320129365.1 " discloses a kind of single use pressure-keeping infusion device, this transfusion device venous transfusion in medicine and hygiene fields；This transfusion device is by needle for inserting bottle, flexible pipe, flow regulator, liquid medicine filter, venoclysis needle, dropping funnel and release mechanism composition, wherein release mechanism includes wine bucket lower curtate a protruding medicinal liquid access road, there is a locating part dropping funnel middle and lower part, has a buoyancy aid therebetween, and buoyancy aid is embedded with the diaphragm that a latex is made with other soft material.
China Patent No. discloses a kind of safe transfusion system, this transfusion device venous transfusion in medicine and hygiene fields for " CN201120280062 "；This transfusion device is made up of the feed tube being linked in sequence, Murphy's burette and drain pipe, wherein release mechanism includes lower end is cone shape Murphy's burette, the float corresponding with its lower end shape it is provided with in Murphy's burette, the diameter of float maximum cross section is less than medicinal liquid density more than the internal diameter of drain pipe, the density of float.When having medicinal liquid in Murphy's burette, float is suspended in liquid level, declines float with liquid level and declines, and when medicinal liquid drips sky, float is placed exactly in Murphy's burette lower end, cuts off the path of Murphy's burette and drain pipe, effectively prevents air from entering in patient body.Therefore, transfusion device of the present utility model can prevent air bubble from entering patient's vein by means of the buoyancy aid self-closed infusion pipeline in release mechanism.
The most generally there are following some shortcomings in above-mentioned patent: one is that buoyancy aid is all dependent on seal membrane with the medicine liquid outlet bottom dropping funnel or the sealing between the medicine liquid outlet of housing bottom and carries out contacting sealing in plane, when there is certain space inside seal membrane and buoyancy aid, easily produce bubble when transfusion replaces；Two is that the required precision at the medicine liquid outlet fitted seal bottom buoyancy aid and dropping funnel is high, and existing production technology is extremely difficult to the requirement fully sealed, and causes sealing reliability the highest, and safety is the lowest；Three is owing to seal membrane is for realizing effective environmental sealing export department so must be designed to relatively thin so that in practice, the jag of export department because of medicinal liquid easily pierces through diaphragm, causes sealing.
