Description

Puncture needle fixing support

Technical Field

The utility model relates to an external fixed bolster that clinical diagnosis and treatment in-process used, and especially relate to a pjncture needle fixed bolster.

Background

Vascular puncture is a common clinical examination and treatment, with venipuncture being the most common. The operation process mainly comprises the following steps: 1. penetrating the puncture needle head through the skin and the blood vessel wall into the blood vessel; 2. fixing the puncture needle on the surface of the skin; 3. injecting medicine or collecting blood; 4. the puncture needle head is pulled out and hemostasis is pressed. Most of the puncture needles which are commonly used in clinic at present are directly fixed on the surface of the skin by using adhesive tapes. In the operation process, the medical staff firstly pricks the puncture needle into the blood vessel, and then the tail part of the puncture needle is fixed on the surface of the skin by replacing the hand and holding the adhesive plaster. The risk of this operation is: 1. in the process of pasting the adhesive plaster, the puncture needle is triggered, so that the needle head moves in the blood vessel, the endothelium of the blood vessel is scratched, and even the blood vessel wall is accidentally injured, punctured or the needle head slides out of the blood vessel; 2. the fixing is difficult to be firm and the sliding is easy; 3. when the needle is pulled out, the adhesive plaster is required to be firstly removed, the puncture needle can be continuously touched in the process of removing the adhesive plaster, and the accidental movement of the needle head in the blood vessel easily damages the inner wall of the blood vessel and even accidentally punctures the blood vessel wall; 4. when withdrawing the needle, the puncture needle is hoped to be withdrawn along the axial direction of the needle head accurately, but the puncture needle is difficult to do in practical operation, and the needle point can scratch the inner wall of the blood vessel.

During the puncture operation, the puncture needle is expected to be convenient to operate and can be quickly fixed on the surface of the skin; during the period of medicine injection or blood collection after successful puncture, the puncture needle is expected to have good stability, firm fixation and difficult accidental sliding; at the end of treatment, the puncture needle needs to be pulled out conveniently and safely, and damage to the blood vessel is reduced. Therefore, there is a need for a needle holder that can securely hold a needle head and safely and quickly remove a needle when removing the needle.
