Problems solved by technology

[0002] At present, the traditional venipuncture method is the method of tying the tourniquet, which will bring the following disadvantages during venipuncture: (1) When the tourniquet is tied, poor peripheral venous circulation or failure will cause poor venous filling
(2) The tourniquet at the ligation site oppresses the skin, the pressure cannot be adjusted, and the ligation site can also cause pain
(3) When the tourniquet is loosened, the pressure suddenly drops, and the pulling or rapid recovery of the blood vessel will easily cause the needle tip to puncture the blood vessel or come out of the blood vessel, resulting in blood leakage and puncture failure
[0003] The existing application number is 201220085585.8, a utility model patent for a pressure belt for venipuncture. The device includes a pressure belt body made of elastic material. The shape of the pressure belt body is trapezoidal. And the bottom is provided with several elastic material fixing belts successively, and the fixing belts are connected to the other side of the trapezoidal pressurization belt body through the connectors. The utility model is evenly stressed and the patient feels comfortable, but it is still difficult to solve the problem of loosening the pressure. When the pressure drops suddenly, the pulling or rapid recovery of the blood vessel will easily cause the needle tip to puncture the blood vessel or come out of the blood vessel, resulting in blood leakage and puncture failure. At the same time, the pressure cannot be adjusted, and the function is limited.

Abstract

The invention provides a vein puncture device which comprises a vein displaying device and an adjustable air pressure belt. The vein displaying device and the adjustable air pressure belt are used in cooperation. When the vein puncture device is applied to vein puncture, area of a local tourniquet of an air pressure tourniquet is enlarged and the pressure of the tourniquet can be adjusted, so that the vessel is inflated, pressure after puncturing is gradually reduced and exudation of liquid is relieved. The advantages of the adjustable air pressure tourniquet can be better developed when the adjustable air pressure tourniquet is applied to patients suffering coma, shock, hemorrhage and poor peripheral circulation and the elderly with difficult vein puncture. The piercing of the vessel by a needle point is avoided. As a vein easy-displaying red light illuminating device and an infrared heating device are arranged, the local blood circulation is accelerated, displaying of the vein is enhanced, and therefore the puncture success rate is improved. A disposable bacteria-free isolation cushion is used for preventing cross infection among patients.
