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.

Embodiment 1

[0032] Embodiment 1: As shown in the figure, a vein developing device includes a fixing base 1, a connecting assembly 2, a transmission mechanism 3 and a needle connecting mechanism 4 located directly above the fixing base 1, and a developing lamp 11 is arranged on the fixing base 1 , image acquisition device, image processing module, knob switch 12, photosensitive switch 13 and wrist limit assembly 5, developing lamp 11, knob switch 12 and photosensitive switch 13 are electrically connected in sequence; the image acquisition device will collect the distribution of subcutaneous veins image, the image processing module determines the best position of the blood vessel to be injected according to the distribution image and generates position coordinate information and sends it to the transmission mechanism 3, the transmission mechanism 3 is connected to the fixed seat 1 through the connection component 2, and the transmission mechanism 3 connects the needle according to the coordin...

Embodiment 2

[0034] Embodiment 2: The other parts are the same as Embodiment 1, the difference is that the connecting assembly 2 includes a left connecting frame 21 connected to the left side of the fixing base 1 and a right connecting frame 22 connected to the right side of the fixing base 1 .

Embodiment 3

[0035] Embodiment 3: The remaining parts are the same as Embodiment 2, the difference is that the transmission mechanism 3 includes a transverse transmission assembly 31 and a longitudinal transmission assembly 32 arranged on the transverse transmission assembly 31, and the two ends of the transverse transmission assembly 31 are respectively connected to the left The frame 21 and the right connecting frame 22 are connected, and the longitudinal transmission assembly 32 is connected with the needle connecting mechanism 4 .

[0036] The horizontal transmission assembly 31 includes a first servo motor 311, a first horizontal screw rod 312, a second horizontal screw rod 313, a first horizontal vertical screw rod 314 and a second horizontal vertical screw rod 315, the first horizontal horizontal screw rod 312 The two ends of the left connecting frame 21 and the right connecting frame 22 are rotatably connected respectively; The two ends of the second horizontal longitudinal screw r...

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 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 this group of peopl...
