Control method of vein developing unit

Abstract

The invention discloses a vein developing unit, characterized by comprising a fixing seat, a connecting component, a transmission mechanism and a syringe needle connecting mechanism located right above the fixing seat, wherein the fixing seat is provided with a developing lamp, an image acquisition device, an image processing module, a knob switch, a light sensation switch and a wrist limiting component, and the developing lamp, the knob switch and the light sensation switch are electrically connected in sequence; the image acquisition device acquires an distribution image of subcutaneous veinblood vessels, and the image processing module determines the position of a needed blood vessel according to the distribution image, generates position coordinate information and sends to the transmission mechanism, the transmission mechanism is connected with the fixing seat through the connection component, the transmission mechanism enables the syringe needle connecting mechanism to freely perform longitudinal and lateral movement according to the coordinate information, and the syringe needle connecting mechanism is arranged on the transmission mechanism in a manner of moving up and downvertically, thereby driving an injection syringe needle to move up and down. The advantage is that the puncture success rate can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field, in particular to a control method of a vein developing device. Background technique [0002] Intravenous injection is a medical method that directly injects liquid substances such as blood, medicinal liquid, and nutrient solution into a vein. Intravenous injection can be divided into transient and continuous. Transient intravenous injection is like a common injection, and continuous intravenous injection is like dripping. Both injection methods require the injection needle to be inserted into the vein through the skin. [0003] For some groups of people, for example, obese patients have thicker subcutaneous fat, and the veins are not easy to highlight; for patients with edema, the veins cannot be seen clearly due to tissue edema; and for children who do not cooperate with injections, the veins themselves are relatively thick Thin, it is not easy to accurately insert the injection needle into the vein. For...

AI Technical Summary

Problems solved by technology

[0003] For some groups of people, for example, obese patients have thicker subcutaneous fat, and the veins are not easy to highlight; for patients with edema, the veins cannot be seen clearly due to tissue edema; and for children who do not cooperate with injections, the veins themselves are relatively thick Thin, difficult to accurately insert the injection needle into the vein

For this group of people, even for experienced medical staff, the puncture success rate is not high, and repeated needle injections will cause great distress to medical staff and pain to patients.
