Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific examples. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but not to limit the present invention.

[0022] Such as figure 1 As shown, the area to be detected (1) of the patient is placed in the intersecting interval of the binocular or multi-eye infrared camera (3), and the calculation processing unit (6) controls the infrared multispectral light source (4) to illuminate the area to be detected (1) of the patient at a specified wavelength. ) for a certain period of time, the lighting sequence is as follows figure 2 As shown, the calculation processing unit (6) removes noise through image filtering according to the image taken by the binocular or multi-eye infrared camera (3), and performs stereo matching on the blood vessel image to realize the calculation of the three-dime...

Abstract

The invention aims to provide an auxiliary medical device which can directly display the patient vein position and depth information on the skin surface. The device consists of a multi-spectral infrared source, multipath cameras, a visible light interception infrared transmission filter, projection display equipment and a computation processing unit; According to the technical scheme, the infrared source emits one or a plurality of near-infrared lights to a detected part, the infrared lights are reflected by the skin and enter the cameras through the visible light interception infrared transmission filter, the cameras can acquire the skin images from different angles, the position and depth images of the vein can be obtained through the computation processing unit, the projection display equipment has the function of projecting the computed vein image position and depth information to the corresponding skin part, so that a doctor can obtain the vein position and depth information of the part to be injected, and the injection success rate is improved.

Description

technical field [0001] The present invention is a medical auxiliary device, and specifically relates to a virtual enhanced display method for infrared vein stereoscopic imaging. The device can be used to collect patient veins and directly project them on the patient's body surface, assisting doctors to complete the three-dimensional venipuncture. guide. Background technique [0002] Venipuncture is a very common and very important medical operation, especially when the critically ill patients are to be rescued quickly in an emergency, it is particularly important to be able to puncture successfully quickly. However, it is not easy to perform venipuncture quickly and accurately: obese patients have thick subcutaneous fat and deep veins, so the tourniquet must be tightly tied during venipuncture; patients with edema are difficult to see due to the cover of tissue edema. When Qinghe touches the blood vessel and tightens the tourniquet, he needs to press the puncture site with ...
