Elastic connector of soft bag for infusion

Abstract

The invention discloses an elastic connector of a soft bag for infusion. The elastic connector comprises an upper port, an infusion passage and a tail lug. The elastic connector is characterized in that two ends of the infusion passage are connected with the upper port and the tail lug respectively; the cross section of the lower end of the infusion passage is a circular, elliptical or diamond frame; the side wall of the lower end of the infusion passage is elastic and deformable; and the elastic connector of the soft bag for infusion is an integrated component. The tail lug at the lower end of the elastic connector of the soft bag for infusion is connected with the body of the soft bag for infusion, and the side wall of the lower end of the infusion passage is elastic and deformable, so that the cross section of the lower end of the infusion passage deforms into a slit when pressed by an upper mold and a lower mold during heat sealing for bag making, and then rebounds to the original shape approximately after bag making is finished. The elastic connector of the soft bag for infusion is convenient to position and low in consumption of materials during bag making, and the production cost can be reduced evidently when the seepage rate is reduced effectively.

Description

technical field [0001] The invention belongs to the field of medical supplies, and more specifically relates to an elastic interface for infusion of a soft bag. Background technique [0002] Today's soft bag infusion ports all adopt hard ports, and the port connected with the infusion bag is rhombus-shaped, and cannot be deformed, and the infusion channel at the port is circular. Today's soft bag infusion interface is a hard diamond-shaped interface. In order to meet the requirements for the connection between the interface and the infusion soft bag, the interface precision is relatively high, otherwise there will be connection problems such as leakage, so the mold precision requirements are also relatively high during the processing of the interface. High, resulting in high production costs for the infusion interface; in the process of connecting with the soft bag (that is, the heat-sealing connection between the hard rhombic interface and the infusion soft bag), because th...

Problems solved by technology

Today's soft bag infusion interface is a hard diamond-shaped interface. In order to meet the requirements for the connection between the interface and the infusion soft bag, the interface precision requirements are high, otherwise there will be connection problems such as leakage, so the mold precision requirements are also relatively high during the processing of the interface. High, resulting in high production costs for the infusion interface; in the process of connecting with the soft bag (that is, the heat-sealing connection between the hard rhombic interface and the infusion soft bag), because the interface is hard and not easy to deform, the processing accuracy is very high during the connection process. , during the connection process, it needs to be connected multiple times and needs to be moved, resulting in low connection efficiency and connection qualification rate; the interface is diamond-shaped, so it has a certain slope, the higher the slope, the lower the yield
