Problems solved by technology

[0002] In the clinical venipuncture process, because some patients have small blood vessels, it is difficult to find; there are also some trauma patients who lose too much blood and the blood vessels are not filled, so that the nurses cannot find the blood vessels during the intravenous injection, and repeatedly puncture the needle, which makes the patient Not only physical pain, but also mental tension, and the doctor-patient relationship is also very tense
After retrieving domestic and foreign literature, there is no relevant report at present, and there is no instrument to assist venipuncture on the market

Embodiment Construction

[0011] picture Among them, the present invention is a vein and blood vessel imaging system composed of an infrared emitting device 1 , a corresponding near-infrared receiver 2 and a head-mounted display 5 . The infrared emitting device 1 is composed of several near-infrared diodes connected in parallel, and each infrared emitting diode emits infrared rays with a wavelength of 800-850nm. The near-infrared receiver is a black-and-white low-light high-resolution camera with an 800nm ​​infrared filter 4 installed in front of the lens 3. The display is a head-mounted video glasses, which are connected with the matching high-resolution camera. picture The image is presented by the head-mounted display 5 . For patients whose blood vessels are difficult to find, in the specific operation, first connect the power supply 6, then put on the monitor, let the patient hold the infrared emitting device 1, and then the patient puts his hands on the infrared filter 4 in front of the lens 3, a...

Abstract

The head carried venous puncture leading instrument is one venous imaging system comprising infrared emitter, infrared receiver and head carried display. The infrared emitter consists of several near infrared LEDs of 800-850 nm emitted wavelength. The infrared receiver is one low-irradiation high-resolution white and black video camera with one 800 nm infrared filter before its lens. The display is one head carried spectacles connected to the video camera. The present invention makes it possible to watch the veins on dorsum of hand clearly and is used in venous puncture to facilitate the vein searching.

Description

technical field [0001] The invention relates to an instrument that can help medical staff to perform intravenous injection in clinic, especially a head-mounted venipuncture guide that can help find blood vessels during venipuncture. Background technique [0002] In the clinical venipuncture process, because some patients have small blood vessels, it is difficult to find; there are also some trauma patients who lose too much blood and the blood vessels are not filled, so that the nurses cannot find the blood vessels during the intravenous injection, and repeatedly puncture the needle, which makes the patient Not only physical pain, but also mental tension, and the doctor-patient relationship is also very tense. After retrieving domestic and foreign literature, there is no relevant report at present, and there is no instrument to assist venipuncture on the market. Contents of the invention [0003] The purpose of the present invention is to provide a head-mounted venipunctu...
