Abstract

The invention discloses a hand back vein injection instrument based on an infrared imaging technology. The injection instrument comprises a control panel, an infrared imaging part, a mechanical injection part, a fixed part and an instrument framework, wherein a horizontal adjusting rod in the mechanical injection part is parallel with two horizontal sliding rods, and is positioned above a center line position of a rectangle formed by four stepping motors; an injection rod is respectively connected with the horizontal adjusting rod and the horizontal sliding rods; 5 stepping motors are respectively connected with a stepping motor driving module; the stepping motor driving module is connected with a single chip microcomputer; the single chip microcomputer is connected with a computer through a digital serial port. The injection instrument is convenient for adjusting of the injection angle, greatly improves the injection stability of the injection rod, can help patients and medical care personnel to remove the interference of human factors, so as to rapidly and accurately accomplish vein injection, and improves the success rate of hand back vein puncture.

Description

technical field [0001] The invention relates to an intravenous injection instrument in the field of medical equipment, in particular to an intravenous injection instrument on the back of the hand based on infrared imaging technology. Background technique [0002] Venipuncture is a very common medical procedure. However, under current medical conditions, it is difficult to perform venipuncture accurately and rapidly by relying on manual needle pricking. Especially for patients with inconspicuous veins such as children, the elderly and obese people, relying solely on the experience of nurses sometimes cannot effectively guarantee the success of puncture. [0003] Foreign statistical data show that: the first-time puncture failure rate of ordinary adult intravenous injection is 28%; 23-28% of needles were missed; 12% of cancer patients had complete failure of puncture; among inpatients, 25% had difficulty in puncture three days after admission. Due to the shortage of medical...
