Auxiliary device, adjustment method, and equipment for automatic adjustment of hand vein imaging quality

Abstract

The invention relates to an auxiliary device, an adjustment method and equipment for automatic adjustment of hand vein imaging quality, and belongs to the technical field of medical instruments. The device adopts a near-infrared transmission method, so that the near-infrared light of a near-infrared light source transmits the palm of a target user from the palm to the hand back and enters a camera. After calculation processing, the number, positions and control signals of the near-infrared light sources are automatically adjusted according to the vein image quality, and the uniformity of the hand vein imaging quality of different target users is achieved. Meanwhile, by arranging a hand back positioning platform and an arm support, the arm and the palm of the target user can be effectivelysupported and positioned, and can assist a doctor or an automatic puncture device in puncturing.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an auxiliary device, an adjustment method and equipment for automatically adjusting the imaging quality of dorsal hand veins. Background technique [0002] Venipuncture is the most important basic link in clinical diagnosis and testing such as blood drawing and infusion, and it often requires medical staff to undergo a lot of training to master it. However, in the face of patients whose veins cannot be visually inspected, such as obesity, children, and the elderly, medical staff cannot ensure successful puncture based on experience alone, especially in isolation wards, because medical staff need to wear heavy isolation gowns and protective clothing, wear Goggles, N95 masks, and multi-layer rubber gloves are used for protection. There are clinical problems that the vision is blurred due to the fogging of the goggles and the vein cannot be found, and the multi-l...

Problems solved by technology

[0004] However, irradiating the back of the hand with a near-infrared light source can only obtain images of the superficial veins on the back of the hand, but cannot represent the depth level information of the veins, and cannot image the deeper veins on the back of the hand, thus affecting the accuracy of venipuncture on the back of the hand

And through the near-infrared light source to transmit the entire palm, all the vein images on the back of the hand can be obtained. However, due to individual differences, it is difficult to ensure the quality of vein images on the back of the hand with a single fixed light source.
