Abstract

The utility model discloses an automatic-exhaust transfusion system, which comprises a bottle stopper puncture outfit protective sleeve, a bottle stopper puncture outfit, an exhaust short conduit, an air filter, a dropping funnel, a dropper, a flow regulator, a transfusion long conduit, a soup filter and a disposable venous transfusion needle. The dropping funnel comprises a dropping funnel cover and a dropping funnel body. The left end of the dropping funnel cover is machined with a soup injection device. The automatic-exhaust transfusion system is characterized in that the right end of the dropping funnel cover is equipped with an integrated automatic exhaust apparatus formed by an exhaust needle, a dropping funnel air filter and a venting plug. The dropping funnel air filter is fixed to the bottom of the exhaust needle. The central section of the exhaust needle is equipped with an exhaust needle bore communicated with the dropping funnel air filter for air circulation. An air filtering film or a filtering plug is arranged inside the dropping funnel air filter for preventing bacteria and dusts from entering the transfusion system. During the transfusion process, the transfusion system can automatically exhaust so as to reduce the labor intensity of medical staff, which also has the advantages of easy processing, high yield rate, simple structure and safe and reliable performances.

Description

A kind of self-venting transfusion device

Technical field

This utility model relates to the aseptic medical equipment that is used for the clinical transfusion purposes, especially relates to a kind of transfusion device with automatic vent function.

Background technology

At present, the general infusion set that medical field is commonly used is formed by bottle plug puncture unit protective sleeve, bottle plug puncture unit, transfusion tubulature, aerofluxus tubulature, air filter, dropper, dropping funnel, flow regulator, transfusion long duct, liquid medicine filter and disposable use venoclysis needle.General infusion set is before transfusion, and medical personnel must be artificial with the whole emptyings of the bubble in the transfusion device pipeline, if bubble gets in patient's body, is prone to cause harm such as aeroembolism; Common artificial deflated method is: after bottle plug puncture unit is inserted transfusion bottle stopper; Hang upside down dropping funnel earlier; And squeeze dropping funnel with hands, medicinal liquid is inhaled in the dropping funnel, in this process; Medicinal liquid is discharged the gas in the dropping funnel downwards easily and is formed in the long transfusion catheter of gas-liquid mixture entering, therefore produces bubble; After treating that medicinal liquid is full of about 2/3 volume of dropping funnel, put down dropping funnel, medicinal liquid flows to the intravenous needle direction; But because the surface tension effects of transfusion long duct inwall, the inwall of long duct is a spot of bubble of absorption easily, and medical personnel are again with finger springing transfusion long duct; The bubble of absorption could slowly rise in the dropping funnel; The process of this artificial aerofluxus bubble was not only loaded down with trivial details, difficulty but also increase working strength, also lost time, and also was unfavorable for promptly infusing and giving emergency treatment to a patient.

And in the clinical transfusion process; Usually in the limited time, medical personnel will be responsible for patient's in several wards transfusion operation, and labor intensity is very big; Therefore; In clinical transfusion operation, a kind of easy and simple to handle, infusion set with automatic vent function is provided, be used for improving medical personnel's work efficiency and to reduce labor intensity just particularly important.

Summary of the invention

The purpose of this utility model be to provide a kind of can automatic vent, easy and simple to handle in infusion process, the transfusion device that yield rate is high, safe and reliable.

The purpose of this utility model is achieved in that

A kind of automatic-exhaust transfusion device; Comprise bottle plug puncture unit protective sleeve, bottle plug puncture unit, aerofluxus tubulature, air filter, dropping funnel, transfusion tubulature, dropper, transfusion long duct, flow regulator, following liquid injecting piece, liquid medicine filter and disposable use venoclysis needle; Dropping funnel is made up of dropping funnel lid and dropping funnel body; The left end that covers at dropping funnel is processed with liquid injection device; Characteristic is: the right-hand member that covers at dropping funnel is equipped with the automatic exhaust device of being made up of incorporate exhaust needle, dropping funnel air filter and venting plug; Exhaust needle is passed down through the dropping funnel lid and is positioned at dropping funnel, is fixed with the dropping funnel air filter that is positioned at dropping funnel in the bottom of exhaust needle, is provided with an exhaust needle endoporus that is communicated with and supplies circulation of air with the dropping funnel air filter at the middle part of exhaust needle; In the dropping funnel air filter, be provided with and filter air filtration film or the filtering plug that gets into air in the dropping funnel through the exhaust needle endoporus, prevent that antibacterial and dust from getting into; Be fixed with the venting plug that can cover or open the exhaust needle endoporus at the right-hand member edge of the exhaust needle that places the dropping funnel side of covering.

The operation principle of automatic exhaust device: in the process that transfusion operation begins; Automatic exhaust device can be discharged the gas in the dropping funnel automatically; It can effectively prevent the generation of bubble and prevent that bubble from getting in the transfusion long duct, make the process of transfusion aerofluxus bubble not only easy but also quick.

This utility model is on the basis of traditional disposable infusion set, to have set up to have and can prevent that bubble from getting into the automatic exhaust device of human body by degassing function.This utility model is the same with the transfusion set operating procedure in use, does not change operator's use habit, also can reduce the loaded down with trivial details step that manual work squeezes dropping funnel aerofluxus bubble.

When this utility model uses, earlier bottle plug puncture unit is inserted in the infusion vessel bottle stopper, do not need to squeeze dropping funnel, need not hang upside down dropping funnel with hands; Medicinal liquid gets in the dropping funnel automatically, and the air in the dropping funnel is all discharged through automatic exhaust device, and the liquid level of medicinal liquid constantly rises, and medicinal liquid gets in the transfusion long duct again; Flow out from venoclysis needle needle tubing endoporus, get rid of bubble automatically, close flow regulator, by conventional method puncture vein; Open flow regulator, regulate to drip speed, but both normal infusion.Among this process, also bubble-free sneaking in the whole communication path in can be as the general infusion set not direct entering transfusion of the bubble long duct, thereby prevents that effectively bubble from producing.

Therefore; The utlity model has following advantage: 1, in transfusion operation process in early stage; Need not squeeze dropping funnel both can introduce medicinal liquid in the dropping funnel; Simplify the bleeding step, alleviate medical personnel's working strength, it solves existing transfusion device and steeps the problem loaded down with trivial details, that lose time of working in infusion process because of aerofluxus; 2, need not hang upside down dropping funnel both can discharge the gas in the dropping funnel automatically; Can prevent that bubble from producing and prevent that bubble from getting in the infusion pipeline; And the liquid level in the dropping funnel can be controlled at a certain level altitude automatically, prevents that the liquid level in the dropping funnel is too high, is difficult to observe medicine liquid droplet speed; 3, simple, safe and reliable, the easy processing of product structure, the step that simplifies the operation does not change operator's use habit, can be widely used in clinical.
