Vascular protector for transfusion

Abstract

The invention relates to a vascular protector for transfusion. A needle handle (1), a needle handle head (6), a needle stem (9) and a fin (2) are connected with the bottom of a fin bracket (3) into an integral body; pins (5) on both sides of a portal bracket (4) are clamped in pin holes (11) of the fin bracket; and the fin bracket (3) is matched with the pins (5) through the pin holes (11) and a clamping groove (12), and can rotate around the pins (5). The combination of the fin bracket and motion preventing bracket of the protector is very scientific, so that the fin bracket and motion preventing bracket are very convenient and simple in the production, assembly and transfusion processes. The vascular protector has a light structure. The vascular protector has excellent fixation effect with the skin of the patient; the length of the needle stem is more scientific and reasonable; and thus, the vascular protector can protect the patient vessels in many aspects, and maximally relieve the patient vessels of mechanical injury.

Description

technical field [0001] The invention relates to a medical device for transfusion, in particular to a transfusion blood vessel protector. Background technique [0002] When using a disposable infusion set for intravenous infusion, although there is tape to fix the needle and the front end of the infusion tube connected to it, but because the needle is not firmly fixed, the blade of the needle handle slides relative to the skin, and the vein bends, when the patient's limbs occasionally During the movement, the phenomenon of needle running is prone to occur, causing blood vessel damage, resulting in pain, swelling, heavy tying and waste of liquid medicine. [0003] In clinical intravenous infusion, the longer the length of the needle, the greater the mechanical stimulation and damage area of ​​the needle stem to the blood vessel wall, the more serious the damage, the more blood components leak out, the blood vessel congestion is obvious, resulting in connective tissue hyperplas...

AI Technical Summary

Problems solved by technology

But to form a convenient, quick, flexible and reliable connection between the two, so that their functions complement each other and maximize the protection of the patient's blood vessels during infusion, their respective structures still need to be coordinated.
