Description

A kind of multifunctional transfusion system

Technical field

The utility model belongs to medical instruments field, especially a kind of multifunctional transfusion system.

Background technology

Venous transfusion is the Main Means of clinical treating disease, and the patient for having 90%-95% need to carry out infusion treatment, and it is In most basic operating technology in clinical position, present venous transfusion, disposable transfusion device used, and Open system in the past Compare, make great progress.But with extensive use clinically, it has been found that the disposable transfusion device used at present Still have some deficits and be worth improvements, it is desirable to after innovation improvement, performance can be allowed to and quality is lifted, so as to improve Nursery work efficiency, ensures patient infusion safety.

During clinical transfusion, often have filter junction loosen cause slip, particularly old man, children with it is restless Patient is common, is easily caused site of puncture blood back, causes patient panic, increases the probability of pollution, even causes unnecessary sometimes , there is potential safety hazard in medical tangle.If in addition, having when emergency case or drug combination, it is necessary to which after-teeming decoction is controlled immediately Treat, conventional method is venipuncture or separates transfusion device scalp acupuncture, connect the direct after-teeming decoction of syringe；Former approach is again The probability of the pain that can increase patient and increase infection is punctured, the latter's method joint is repeatedly opened exposure in atmosphere, both increased Add the chance of pollution, the triviality of operation added again, is filtered during separation scalp acupuncture intravenous injection decoction without filter, Easily by not sufficiently dissolved drug microparticles afferent veins, research, which confirms that particulate enters with transfusion, may cause transfusion anti-in human body Should, phlebitis, thrombus, granuloma, thrombopenia, severe patient can cause death；In addition, scalp acupuncture pintle during liquid medicine injection The interior micro-air that always has is difficult discharge, quickly enters vein with decoction, air embolism is caused when serious.In clinical transfusion process In exhaust often occur insufficient, cause have gas in hose of infusion apparatus lower part, at this time may will be it is difficult to be vented This block is separated filter with scalp acupuncture junction, is then vented, then scalp acupuncture near-end flexible pipe can only use hand reflexed, both add The triviality of operation, and easily cause blood back because reflexed loosens.

Clinically in infusion process, often occur infusing not smooth, one reason for this is that, suffer from because transfusion time is longer Person's often changing position, easily makes pinpoint inclined plane be close to cause transfusion not smooth with vein, if now regulation needle handle direction is invalid, Then need to puncture again, increase patient pain and infection probability are easily caused phlebitis.

Present China originates from the U.S. of the sixties using disposable transfusion device, the eighties incoming China.With modern times doctor That studies science is developed rapidly, and medical supplies are constantly updated, and the own popularity of disposable transfusion device is applied to clinic.It is disposable defeated Liquid (blood) device is that current China's application is most wide, the maximum disposable medicine equipment of quantity, in the consumption of China every year It is 5,000,000,000, and all increases every year in certain proportion.Therefore, the deficiency that this research will exist according to traditional infusion device, if A kind of novel screw type multifunctional transfusion system is counted out, is that clinical care offers convenience.

Utility model content
