Abstract

The invention belongs to the field of medical instruments, and particularly relates to a novel dripping core for children. The novel dripping core can be guaranteed to accord with the State Standard of the People's Republic of China, complex structures and various processes are removed, and risks are lowered. The novel dripping core for the children is composed of a liquid inlet, a liquid outlet and a dripping chamber cover. The novel dripping core for the children is formed in a one-time injection molding mode through an injection molding machine. Compared with the prior art, the novel dripping core for the children has the advantages that the appearance of products is attractive, the products accord with the State Standard of the People's Republic of China, the process design is simple and convenient, safety and sanitation are achieved, man-made pollution is reduced, the degree of automation is high, efficiency is high, the risk is small, operation is smooth, and manpower and material resources are saved.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a novel drip core for children. Background technique [0002] The National Standard of the People's Republic of China for Gravity Infusion Type of Disposable Infusion Sets (GB8368-2005) has made the following requirements for the dripping funnel and the dripping tube: the dripping funnel should be able to observe the droplets continuously. The liquid should enter the dropping funnel through a dropper inserted into the dropping funnel. The distance from the end of the dropper to the outlet of the dropper should not be less than 40mm, or the distance between the dropper and the liquid medicine filter should not be less than 20mm. The distance between the wall of the drip funnel and the end of the drip tube should not be less than 5mm. Under the conditions of (23±2)°C and a flow rate of (50±10) drops / min, 20 or 60 drops of distilled water from the dropper should be (1±0.1)ml{(1±0.1)...
