Method for improving definition of body surface veins and vein puncture observation instrument

Abstract

The invention discloses a method for improving definition of body surface veins and a vein puncture observation instrument. The method comprises the following steps: (1) adopting a red light source to transmit subcutaneous tissues; (2) adopting a green light source to transmit the subcutaneous tissues; (3) adopting a blue light source to transmit the subcutaneous tissues; (4) repeatedly and alternately executing the steps (1), (2) and (3), wherein the order of the steps (1), (2) and (3) can be changed, but the steps are alternately executed; and the alternating time space is 1 / 24 second. The vein puncture observation instrument is provided with three LED light sources: red, green and blue lights sources; and a collector lens is arranged over the three LED light sources. A switch controller of the three light sources for alternately lighting and a time space controller are arranged in the control mechanism of the three LED light sources. The method and the device of the invention can help operators clearly see the positions and distribution situations of the body surface veins, so the medical operations, for example, body surface vein punctures, can be conveniently executed.

Description

technical field [0001] The present invention relates to an auxiliary method for medical operation and its equipment, in particular to a method capable of improving the clarity of human superficial tissue and body surface veins, and the equipment used in the method: a venous blood vessel puncture observer (body Surface Vein Vascular Puncture Observer). Background technique [0002] Body surface venous puncture is one of the basic operating techniques often used in the medical field. Although this is the most basic operation technique, it often presents great difficulties in clinical practice. For example, when encountering obese patients with slender blood vessels, the blood vessels are difficult to see clearly. It becomes very difficult to find blood vessels and accurately puncture them. tricky operation. For another example, the blood vessels of young patients are also very slender, and the skin is soft and vulnerable, and their body surface venous puncture is also a diff...

Problems solved by technology

[0003] However, in the prior art, there is no technical method and equipment that can assist the operator to see clearly the position and distribution of the superficial tissue of the human skin and the surface veins; or directly use light transmission to assist in enhancing the contrast to project the surface veins , the site of surgery is limited
