Problems solved by technology

It can be seen clinically that when adding medicine to a patient, the medicine liquid added will go from bottom to top, and cannot enter the human body at the first time. The needle-free connectors directly enter the human body when the drug is added, and the liquid is not filtered, and the particles that may exist in the liquid also enter the human body, causing potential danger

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a needle-free drug dosing device. Background technique [0002] At present, patients often add medicine in the middle of the infusion process, especially for seriously ill patients. The old way of adding medicine is to use a syringe with a needle to directly add medicine through the injection part. There is a risk of needle stick injury. Hospitals are now implementing zero tolerance for steel needles, so needle-free dosing methods will gradually replace traditional dosing methods. It can be seen clinically that when adding medicine to a patient, the medicine liquid added will go from bottom to top, and cannot enter the human body at the first time. The needle-free connectors directly enter the human body when the medicine is added, and the liquid medicine is not filtered, and the particles that may exist in the medicine liquid also enter the human body, causing potential...
