Description

A kind of safe back springing type transfusion needle

Technical field

The utility model relates to the field of medical instrument technology, more particularly to a kind of safe back springing type transfusion needle.

Background technique

Infusion treatment is a kind of people's therapeutic modality common when sick, can be used for supplementing body fluid, electrolyte or Nutriment.

Transfusion needle is disposable medical article, and by blood born, transfusion needle is disease after use in order to prevent It is discarded and is handled.Transfusion needle is to take the shields of plastics on the syringe needle of transfusion needle to prevent from piercing after human body disengaging at present Hurt medical worker and treatment of!medical waste personnel, but shield only simply covers on transfusion needle, it is easy to fall off, still not It can prevent medical worker and waste disposal workers are pierced and caused the infection of disease.

Moreover, when medical staff pulls out the syringe needle, Yi Fasheng needle-stick injury.It is that one kind by syringe needle enters skin that needle, which is stabbed, Deep simultaneously is enough to make the unexpected injury of victim's bleeding.There is infection menses liquid to propagate disease if contaminated syringe needle, sharp instrument injury The danger of disease.

Many studies have shown that nurse is that needle stabs the highest professional colony of occurrence frequency in hospital, incidence is 88.97%, while nurse is also the high-incidence group for infecting Emperical Bayesian method.More than 20 haematogenous can be propagated by being stabbed by needle It spreads the disease, wherein most common, maximum harm is HBV, HCV, HIV.Nursing staff's accidental needle sticks are hurt almost all and are occurred When pulling out liquid, tracing it to its cause mainly has: 1. the operation of tradition separation scalp needle for infusion takes fluid bag, scalp acupuncture after pulling out needle immediately In free state, it is easy to stab the people of oneself and periphery, and when processing pricks the syringe needle of bottle stopper, it is possible to cause blood Secondary pollution.2. the pending article of tradition separation scalp needle for infusion operation institute is put together, easily stab, although medical worker It the injuries such as stabbed, abrade by sharp instrument in curative activity to be still inevitable.

In conclusion needing to design a kind of scalp acupuncture for overcoming disadvantages mentioned above at present.
