Embodiment Construction

[0020] 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.

[0021] Such as figure 1 As shown, the patient’s area to be detected (2) is placed in the middle of the binocular or multi-eye infrared camera (4) and the infrared light source (1), and the infrared image of the dorsal vein of the hand is collected by the infrared camera, and the calculation processing unit (5) according to Images captured by binocular or multi-eye infrared cameras (4) are filtered to remove noise, and stereoscopic matching is performed on vein images to realize the calculation of three-dimensional information of vein vessels, and use grayscale and pseudo-color information to represent the depth information of vein vessels .

Abstract

The invention aims at providing an auxiliary medical device capable of obtaining position and depth information of hand back veins of a human body and relates to a transmission-type hand back vein three-dimensional infrared imager which consists of an infrared source, multi-channel vidicons, a visible light cut-off infrared transmission filter and a computing and processing unit. The technical scheme is that the infrared source emits near-infrared light and irradiates the near-infrared light on a detected region, the infrared light penetrates through a hand back to enter the vidicons through the visible light cut-off infrared transmission filter, the two vidicons can acquire skin images at different angles, a position and depth image of the veins can be obtained after the computing and processing unit performs processing, accordingly the imager assists a doctor to obtain the position and depth information of the veins in a region to be injected, and the success rate of the injection is improved.

Description

technical field [0001] The present invention is a medical auxiliary instrument, and specifically relates to an infrared vein stereoscopic imaging instrument, which can realize the collection of veins on the back of the patient's hand, and obtain the three-dimensional structure diagram of the veins on the back of the hand through computer processing, and assist the doctor 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 vess...
