Problems solved by technology

[0004] The technical problem to be solved is: hope to provide a children's drop core, which can not only ensure compliance with the national standard of the People's Republic of China, but also have no complicated processes, and avoid the number of times of glue produced when the children's drop core is made by itself, that is, avoid the stickiness here. External pollution sources that may be caused by glue can also reduce the air bubbles generated during the infusion exhaust process

Embodiment Construction

[0010] Such as figure 2 As shown, the children's drip core is composed of a liquid inlet (1), a dripping funnel cover (2), a liquid outlet (3), and a dropper (4). The children's drop core is made of one-time injection molding by an injection molding machine. The liquid channel of the children's drip core is a cylindrical cavity, and the end of the liquid channel is conical. The purpose of this design is to facilitate positioning and prevent molds from colliding.

[0011] The liquid outlets are distributed on the side of the lower part of the liquid channel, which greatly reduces the amount of liquid medicine that cannot be infused into the human body and is stored in the infusion set. The number of liquid outlets is two or more, and the lowest points of all the liquid outlets are located at the same On the horizontal line, the total area range of the liquid outlet: 0.28mm 2 -6mm 2 , The top of the liquid outlet has a certain slope to prevent the mold from colliding.

Abstract

The invention belongs to the field of medical instruments, particularly relates to a drip core for children and solves the technical problems that the drip core for children needs to meet the national standard, the process is complex, the times of gluing during production of the drip core for children need to be reduced, and bubbles generated during infusion venting need to be reduced. According to the technical scheme, the drip core for children comprises a liquid inlet, a drip chamber cover, two or more liquid outlets, and a drip tube. The drip core for children is formed once by injection molding with an injection molding machine. The liquid outlets are formed in the side of the lower portion of a liquid passage. The drip tube is arranged at the lowest end of every liquid outlet. The center of the drip tube and the liquid passage locate on a same longitudinal axis. Compared with the prior art, the drip core for children has the advantages that the products are attractive in appearance and meet the national standard, the process is simple, safe and reliable, less man-made pollution occurs, labor and material resources are saved, the risk in gluing the drip core component is avoided, and fewer bubbles are generated during infusion venting.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a drop core for children. Background technique [0002] The national standard of the People's Republic of China for single-use infusion set gravity infusion type (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)g}. 20 ...
