Description
Technical field：
The present invention relates to a kind of disposable medical apparatus, the self-enclosed automatic liquid-stopping transfusion apparatus of specifically a kind of single use.
Background technology：
It is well known that China started to promote the use of common disposable infusion set from the 1980s, the existing history of more than 30 years so far, to preventing cross infection from serving positive role in clinical transfusion；But, also there is certain weak point in common disposable infusion set：When transfusion is completed or transfusion group replaces, air is easily accessible in infusion tube, if processed not in time, air input human body will be on the healthy generation impact of patient；Also increase the nursery work intensity of medical worker simultaneously, easily cause doctor-patient dispute；Therefore it is intended that there is a safer more effectively good product, make the trusting of numerous medical workers and patient, 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 for " CN200810048699 ", the venous transfusion that the transfusion device is used in medicine and hygiene fieldses；The transfusion device is made up of tube for transfusion, funnel and syringe needle, tube for transfusion is connected with funnel and syringe needle respectively, and wherein release mechanism includes the plastic foam ball float in funnel, when the liquid flow in funnel is complete, the liquid outlet of its lower portion will be blocked by ball float, reach the purpose of safe handling.
China Patent No. " 200320129365.1 " discloses a kind of single use pressure-keeping infusion device, the venous transfusion that the transfusion device is used in medicine and hygiene fieldses；The 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 raised 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 a latex and diaphragm made by other soft materials.
China Patent No. discloses a kind of safe transfusion system for " CN201120280062 ", the venous transfusion that the transfusion device is used in medicine and hygiene fieldses；The transfusion device is made up of the feed tube, Murphy's burette and drain pipe being linked in sequence, wherein release mechanism includes lower end for cone shape Murphy's burette, float corresponding with its lower end shape is provided with Murphy's burette, the internal diameter with diameter greater than drain pipe of float maximum cross section, the density of float are less than medicinal liquid density.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 space-time, 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 invention can prevent air bubble from entering patient's vein by means of the buoyancy aid self-closed infusion pipeline in release mechanism.
Above-mentioned patent following some deficiencies of generally existing in actual applications：One be the sealing between the medicine liquid outlet of the medicine liquid outlet or housing bottom of buoyancy aid and dropping funnel bottom be all to carry out contact in plane by seal membrane to be sealed, when there is certain space inside seal membrane and buoyancy aid, transfusion alternately when easily produce bubble；Two is that buoyancy aid is high with the required precision at the medicine liquid outlet fitted seal of dropping funnel bottom, and existing production technology is extremely difficult to the requirement for fully sealing, causes sealing reliability not high, and safety is low；Three are as seal membrane is to realize effective environmental sealing export department so must be designed to relatively thin so that the jag of the export department in practice because of medicinal liquid easily pierces through diaphragm, causes to seal.
The content of the invention：
The invention aims to can control when in infusion bottle, liquid is totally lost liquid or air can not enter human body and can anti-Hemostatic Oral Liquid backflow, realize the purpose of safe infusion, there is provided a kind of single use automatic liquid-stopping transfusion apparatus.
