Description
Technical field
This utility model relates to transfusion device, and particularly automatic vent stops liquid transfusion device.
Background technology
At present; the general infusion set that medical field is conventional forms by protective sleeve for bottle stopper puncture outfit, bottle plug puncture unit, transfusion tubulature, aerofluxus tubulature, air filter, dropper, dropping funnel, flow regulator, transfusion long duct, liquid medicine filter and single use venoclysis needle, and the liquid medicine filtering membrane of general infusion set is not less than 80% for the rejection rate that diameter is 20 ± 1 μm of microgranules.General infusion set is when transfusion just starts, must by manually squeezing dropping funnel, could medicinal liquid be introduced in dropping funnel from infusion bottle, enter the process of dropping funnel by pipeline from dropper at medicinal liquid, gas in dropping funnel is easily discharged formation gas-liquid mixture downwards and is entered in long transfusion catheter by medicinal liquid, therefore bubble is produced, simultaneously, due to the surface tension effects of transfusion long duct inwall, a small amount of bubble is easily adsorbed at the inwall of transfusion long duct, the process getting rid of bubble is comparatively difficult, time-consuming and loaded down with trivial details, if bubble enters in patient body, easily causes the harm such as aeroembolism.So, medical personnel are before infusing, must be artificial by the emptying as much as possible of the bubble in transfusion device long duct, the method of common artificial aerofluxus is: after bottle plug puncture unit is inserted transfusion bottle stopper, first dropping funnel is hung upside down, squeeze dropping funnel with hands simultaneously, medicinal liquid is made to enter in dropping funnel, after a certain amount of liquid is full of dropping funnel, put down dropping funnel, just may by most removal of bubbles, but have a small amount of minute bubbles to be adsorbed on the inwall of transfusion long duct, medical personnel are again with finger springing transfusion long duct, the bubble of absorption could slowly rise in dropping funnel, the process of this artificial aerofluxus bubble is not only loaded down with trivial details but also time-consuming, while the working strength increasing medical personnel, also be unfavorable for promptly infusing and giving emergency treatment to a patient.
And in clinical transfusion process, medical personnel's labor intensity is very large, usual medical personnel will look after the transfusion of patient in several ward, 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, this can cause blood to go back up in a whole set of transfusion device pipeline, or 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.
But existing transfusion device, automatic vent as a kind of in Chinese patent stops liquid precision infusion set, application number: 2010206789649, its dropping funnel adopts syllogic assembling, namely dropping funnel is made up of dropping funnel upper cover, upper dropping funnel shell and lower dropping funnel shell, lower dropping funnel shell offers cannelure, upper dropping funnel shell lower end to be inserted in cannelure and is connected with dropping funnel shell, its packaging technology is complicated, operation is more, production efficiency is low, and cannot ensure the connective stability at upper dropping funnel shell and lower dropping funnel shell, thus causes the production quality of transfusion device not high.

The purpose of this utility model is achieved through the following technical solutions: automatic vent stops liquid transfusion device, it comprises piercing assembly, dropping funnel, flow regulator, transfusion catheter, Connection Block and transfusion needle, described piercing assembly is connected with dropping funnel by a tubulature, dropping funnel is connected with Connection Block by transfusion catheter, transfusion needle is arranged on Connection Block, described flow regulator is arranged on transfusion catheter, described dropping funnel is made up of upper end cover and dropping funnel body, described upper end cover is provided with automatic exhaust device, described dropping funnel body is one-shot forming part, liquid medicine filtering membrane is installed with bottom dropping funnel body, described piercing assembly comprises perforator, perforator is provided with inlet valve installing hole, the bottom of inlet valve installing hole is also equipped with one deck air-filtering membrane, in inlet valve installing hole, inlet valve is installed, and air-filtering membrane is fixed on the bottom of inlet valve installing hole by inlet valve, perforator outside is also set with perforator protective sleeve.
Described automatic exhaust device is made up of air filter and exhaust needle, and exhaust needle is passed down through upper end cover and is positioned at dropping funnel body, and described air filter is communicated with exhaust needle by air filtration hole.
Described upper end cover is processed with the cannelure that Open Side Down, and dropping funnel body to insert in cannelure and is fixedly connected with upper end cover.
Described upper end cover is also provided with seal rubber sleeve.
Described seal rubber sleeve is latex block.
This utility model has the following advantages: automatic vent of the present utility model stops liquid transfusion device, adopt novel dropping funnel structure, during assembling, to stop liquid liquid medicine filtering membrane is loaded on bottom dropping funnel body, and then assemble with dropping funnel upper end cover, its structure is simple, easy to assembly, and automatic vent, automatic liquid-stopping are in one function, safe and reliable, dropping funnel body integration processing, the structure comparing non-integral molding decreases assembling procedure and manufacturing cost, improve production efficiency, and avoid the phenomenon of leakage because assembly welding causes; Liquid medicine filtering membrane is arranged on bottom dropping funnel body, avoids the phenomenon that liquid medicine filtering membrane is destroyed in this transfusion device assembling process, improves the yield rate of this transfusion device and the reliability of transfusion.
