Problems solved by technology

[0003] When a nurse prepares powder or liquid medicine, when the medicine is drawn, the medicine bottle will generate positive or negative pressure, and the liquid spray phenomenon will occur when the positive pressure is positive. If it is splashed on the medical workers, the harmful toxicity of the medicine will cause Injury to medical workers; it is difficult to draw liquid from the syringe under negative pressure, which causes difficulty in dispensing medicine and reduces work efficiency

Abstract

The invention discloses a medicine dispensing needle head and a disposable medicine dispensing needle. The medicine dispensing needle head comprises a needle base and a needle tube; the needle base isconnected with the needle tube, a needle tip is arranged at the front end of the needle tube; the inside of the needle tube is hollow, and the middle part of the outside is sunk to the inside to forman axial groove. According to the medicine dispensing needle head and the disposable medicine dispensing needle, the axial groove is formed in the needle tube, and is an air inlet-output channel whenmedicine of a medicine bottle is sucked, and when medicine is dispensed, air pressure in the medicine bottle is normal atmospheric pressure, and it is avoided that positive pressure or negative pressure is generated in the medicine bottle; the medicine dispensing needle head is simple in structure, can be suitable for various needle heads, and is fast and convenient to operate, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medicine dispensing needle and a disposable medicine dispensing needle. Background technique [0002] Aspirating the liquid medicine in the sealed bottle with a syringe is a common basic nursing operation, and it is also an auxiliary work for completing treatment. When performing intravenous injection, it is necessary to first extract the medicinal solution from a sealed bottle or ampoule, then add it to a carrier (such as normal saline), and then apply it to the patient's body. [0003] When a nurse prepares powder or liquid medicine, when the medicine is drawn, the medicine bottle will generate positive or negative pressure, and the liquid spray phenomenon will occur when the positive pressure is positive. If it is splashed on the medical workers, the harmful toxicity of the medicine will cause Injury to medical workers; when the syringe is under negative pressure, i...
