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 venous vessel imaging system composed of an infrared emitting device 1 , a corresponding near-infrared receiver 2 and a monitor 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 in front of the lens 3. picture The image is presented through monitor 5. For patients whose blood vessels are difficult to find, during specific operations, first plug in the power supply 6, allow the patient to hold the infrared emitting device 1, and then the patient puts his hand under the infrared filter 4 in front of the lens 3, and the near infrared rays sent by the semiconductor light-emitting diodes pass through. Through the human hand, the hemoglobin absorption peak value in the venous bloo...

Abstract

A venous vessel finder is a venous vessel imaging system composed of infrared transmitter, near infrared receiver and monitor. Said infrared transmitter consists of several infrared diodes connected parallelly. Said near infrared receiver is a low-illumination high-resolution camera with a 800-mm infrared filter in the front of its lens. It can be used to easily find the venous vessel on the back of hand.

Description

technical field [0001] The invention relates to an instrument that can help medical staff to perform intravenous injection in clinic, especially a vein finder 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 kind of venous blood vessel finder that is ...
