The invention discloses a system for sensing the pressure of a suction cap and automatically injecting. The invention comprises: a suction motor for increasing the suction pressure of a suction cap for sucking an injection needle; a solenoid valve having a solenoid valve controller connected thereto and having the function of releasing the suction pressure of the suction cap; having A drug injection controller connected to it and a pressure sensor that measures the pressure of the suction cap; a drug injection motor operated by the drug injection controller based on the pressure of the suction needle measured by the pressure sensor; a screw connected to the plunger pusher of the syringe gear nut, the syringe piston pusher pushes the syringe piston along the length direction of the medicine injection support part; the helical gear shaft passing through the helical gear nut and rotating according to the operation of the medicine injection motor; for connecting the solenoid valve, the suction motor, the pressure The sensor and the suction injection needle are connected to each other. Thus, when the suction cap touches the skin, the pressure is sensed and the set amount of medication is automatically injected. Therefore, the precision of drug treatment can be improved.
Description
technical field [0001] The present invention relates to an automatic injection system having one or more injection needles operable in response to sensing pressure, and more particularly, to an automatic injection system that senses pressure between a professional and an automatic injection device And inject medicine automatically and conveniently. Background technique [0002] Since Mesotherapy was proposed by French doctor Dr. Pistor in 1952, this method has been widely practiced in Europe and South America for treatment. The process of mesotherapy usually involves the use of special injection devices and micro-thin syringes to inject small amounts of therapeutic drugs into the skin layer and subcutaneous tissue layer. Conditions targeted for mesotherapy include acute / chronic pain, localized obesity, and conditions requiring cosmetic / plastic surgery. In recent years, mesotherapy has been recognized for its immediate effect of promoting blood circulation and lymphatic cir...
