Abstract

The invention discloses a needleless injection system used for continuously injecting animals, which belongs to the technical field of needless subcutaneous drug delivery system in medical appliances, and comprises an injection tube, a drug storage and a push shot device; the injection tube comprises a tube body provided with a cavity chamber; the cavity chamber at the front end of the tube body is provided with an injection head; the front end wall of the tube body is provided with a drug storage joint connected with the drug storage; the push shot device comprises a magnetic piston movably arranged in the cavity chamber at the back end of the tube body as well as a shell, a ball bearing lock unit, a coupler and a stepping motor which are arranged behind the tube body in sequence; a main push rod with a main spring is arranged in the shell; the front end part of the main push rod is provided with a magnetic element; the back end of the main push rod penetrates the ball bearing lock unit, then movably enters the coupler and is clamped in the coupler; the coupler is hollow; and a nut on the coupler is matched with the screw rod of the stepping motor. The needleless injection system used for continuously injecting animals can be repeatedly used and can automatically suck drug so as to realize quick scale injection; moreover, the needleless injection system used for continuously injecting animals is electrically restored and is convenient to be carried.

Description

technical field [0001] The invention discloses a needle-free injection system for continuous injection of animals, belonging to the technical field of subcutaneous needle-free drug delivery systems in medical equipment. Background technique [0002] Liquid needle-free injection technology has matured in the medical field. It uses power to drive drugs to produce high-speed jets that directly enter the human subcutaneous tissue. The International Organization for Standardization (ISO) promulgated the standard for clinical use of needle-free injection devices (ISO21649:2006) in 2006. [0003] A standard needle-free injector usually consists of two parts: a syringe (ampule) used to inhale, hold and eject the drug, and an ejector mechanism that generates a thrust when triggered. The propelling device includes a power device and a trigger device. Power is usually generated by compressed gas or a spring. According to the number of injections that can be injected in a single ampo...
