Description

Fixing device for transfusion

Technical Field

The invention relates to the field of medical instruments, in particular to a fixing device for infusion.

Background

As is known, intravenous infusion is a rapid and effective administration mode which is widely adopted in China clinically, and can deliver medicines into blood in a short time to achieve the purpose of rapid treatment. At present, various infusion pipelines in clinic are not only short stay but also long stay, and most of the fixing of puncture points is fixed by adopting transparent application, the area of the fixing mode is small, the fixing part is limited, when the hand to be infused unconsciously bends and moves in a large range, the needle head is easy to slip, and the infusion part is swollen. Therefore, effective fixation is the key to ensure the smooth proceeding of the intravenous infusion.

At present, when clinical intravenous infusion is carried out, an infusion needle is fixed on an arm through an adhesive tape, and an elastic bandage is used for fixing the arm joint of a patient, but the gauze bandage has poor elasticity, liquid does not drip when the gauze bandage is wound too tightly, the fixing effect is poor when the gauze bandage is wound too loosely, the infusion part is not convenient to observe, a patient is often wetted when contacting water and infected, and great inconvenience is caused to the patient. Moreover, the latest edition of the "standard on practicing infusion therapy" updated by the INS guideline clearly indicates that the arm joint is prohibited from being fixed by bandage articles in the infusion process, so that the fixing device for infusion is provided for fixing the arm of the patient, which has important significance.
