Abstract

The invention discloses a negative-pressure drug dissolving device, which comprises a push rod and a needle seat. The center of the needle seat is provided with a liquid inlet and outlet. The bracket at the position, the push rod and the needle seat are respectively fixedly connected with the upper end and the lower end of the telescopic tube so that a sealed space is formed in the telescopic tube. The negative pressure drug dissolving device of the invention has the advantages of simple structure, low cost and no pollution in the process of adding drugs.

Description

technical field [0001] The invention relates to a drug dissolver, in particular to a negative pressure type drug dissolver. Background technique [0002] Drug-dissolving syringes, that is, syringes for intravenous infusion and medicine. The syringes commonly used in hospitals are ordinary syringes, which are composed of syringes, pistons and push rods. Medical staff push and pull the pistons through the push rods during operation to achieve suction. Liquid medicine, mixed liquid medicine and other operations. However, in actual use, it is found that since the push rod has no protective effect, when the medical staff perform operations such as suctioning and mixing the liquid medicine, the pollution of the hands will come into contact with the push rod or pass through the air, which may bring harmful substances such as bacteria to the body. The possibility of cross-infection caused by entering the medicinal solution, in addition to air pollution, which will pollute the medic...
