The invention discloses a portable needle-free injector with accurate dosage, which is composed of a thruster, a medicine-drawing interface and a dosage medicine tube. The thruster is composed of an upper casing part, an adjusting part, an injection part, a lower casing part and a safety part. The medicine bottle storing the medicine liquid is inserted into the medicine pumping interface, and is locked by the medicine pumping interface; the front end of the dosage medicine tube is connected to the back end of the medicine pumping interface, and the adjusting handwheel in the adjusting part is turned to extract the medicine liquid, and store it in the dose Inside the drug tube. When injecting, open the safety part, release the injection part, push the push rod assembly in the adjustment part through the thrust spring of the injection part, and then push the core rod and piston in the dosage medicine tube to make the medicine liquid in the dosage medicine tube form a finer liquid The stream is ejected through the nozzle hole in the top of the dosing tube. The medicine liquid dose of the present invention is precise; the dose of the thruster is adjustable, and the gear adjustment is reliable; the medicine pumping interface has strong adaptability; the medicine liquid injection precision is high; the use is safe, reliable and easy to carry.
Description
technical field [0001] The invention relates to a needle-free injector, in particular to a needle-free injector with accurate dosage and portability. The invention belongs to the technical field of medical equipment. Background technique [0002] For thousands of years, drug therapy has been the main way of human medical treatment. Drugs enter the human body in two main ways: oral administration and injection. The traditional injection method is needle injection, that is, the drug is injected into the human body through a stainless steel needle. The disadvantage of this injection method is: it is easy to cause local skin damage, bleeding, swelling and pain, etc., and long-term injection will produce subcutaneous nodules and other unfavorable factors; Not only the pain is significant, but also makes most patients (especially infants) have a sense of fear. [0003] Needle-free injection is a newly developed technology in recent years. It uses the principle of high-pressure ...
