Description
Technical field
The present invention relates to the field of medical instrument technology, more particularly to a kind of disposable infusion connector.
Background technique
Conduit related blood stream infections (CRBSI) are as caused by catheter in blood vessel microorganism, are the most common ICU related
One of sexuality dye, and clinically lead to one of the main reason of severe sufferer death, while also considerably increasing medical shield
Manage cost.According to the research report of U.S. CDC disease prevention and control center, every year since infusion causes cases of infection to be up to 500,000
Example (an example occurs for average minute clock), every year since infusion causes infectious age to reach 12~25%, lethality close to 1/4,
Every year since the nursing expense for the treatment of infection accounts for the 44% of medical totle drilling cost.
Calparine cap is that material is defended in a kind of medical treatment, the outfit equipment for trochar of being generally infused.The effect of calparine cap is to avoid covering
Pipe needle indwelling time is long, occurs to solidify into medicine position and trochar.Calparine cap imitation can carry out good fortune principle to Catheter
Effect improve the working efficiency of nurse to reduce the medical expense of patient, matched with iv cannule, can repeatedly,
It is punctured repeatedly for infusion, lock-on connection when injecting drug, injection heparin sodium can prevent blood backflow and anticoagulant solid.Using calparine cap
Imitation method tube sealing can extend the service life of venous detaining needle, reduce the payment for medical care of patient, no plugging and infection occur, when setting pipe
Between longest 7 days, it is most 5 days short.Vena jugularis externa will connect calparine cap before puncturing, connection scalp acupuncture and lead are vented, successfully puncture
It is fixed afterwards with transparent dressing.It is noted that skin degerming, fixed secured in puncture process, anti-dropout.Vena jugularis externa indwelling is significantly
Patient suffering is reduced, puncture success rate is high, improves working efficiency.
But existing calparine cap still has shortcoming when in use, from a safety viewpoint from, calparine cap exists
It should be ensured that no air penetrates into when use, it is firm to be completely embedded, and cannot fall off, but existing calparine cap is because repeatedly, repeatedly
A possibility that rubber for puncturing and penetrating into there are air and newly exposing causes bacterium to enter transfusion system.Therefore, for above-mentioned
Problem, which improves traditional heparin cap, proposes a kind of disposable infusion connector for reducing conduit related blood stream infections.
Summary of the invention
