Connector provided with breaking valve and specially used for peritoneal dialysis solution bag

Abstract

The invention discloses a connector provided with a breaking valve and specially used for a peritoneal dialysis solution bag. The connector provided with the breaking valve and specially used for the peritoneal dialysis solution bag comprises a medicine adding port pipe and an infusion port pipe, wherein the medicine adding port pipe and the infusion port pipe are arranged at intervals, both the two port pipes are made of rigid plastic, and the two port pipes form an integral structure through a connecting body integrally generated. The connector provided with the breaking valve and specially used for the peritoneal dialysis solution bag overcomes defects existing in an existing dual-flexible-port-pipe structure, is capable of achieving effective locating in the sealing and connecting processing of the dual port pipes and a bag body, ensures the effective sealing connection of the port pipes and the bag body, fundamentally eliminates the connection sealing faces of the infusion port pipes and the breaking valve, and further reduces the potential safety hazards of liquid leakage.

Description

technical field [0001] The invention relates to a peritoneal dialysis fluid bag, in particular to a special interface for the peritoneal dialysis fluid bag with a breaking valve. Background technique [0002] At present, as a plastic bag for peritoneal dialysis fluid, its structure is as follows: figure 1 As shown, the entire structure is composed of a bag body 1' and two soft mouth tubes 11', 12', wherein the soft mouth tube 11' is a medicine feeding tube, which is directly sealed with a cover, and the other soft mouth tube 12' is an infusion solution The mouth tube is connected with the infusion tube through the breaking valve 2'. [0003] Here, the above two soft mouth tubes 11', 12' are arranged at intervals and are independently connected to the bag body 1' by thermoplastic. Because the materials of the soft mouth tubes 11', 12' are relatively soft, they are compatible with the bag body 1'. It is easy to deform and shift during the thermoplastic connection process, wh...

AI Technical Summary

Problems solved by technology

[0003] Here, the above two soft mouth tubes 11', 12' are arranged at intervals and are independently connected to the bag body 1' by thermoplastic. Because the materials of the soft mouth tubes 11', 12' are relatively soft, they are compatible with the bag body 1'. It is easy to deform and shift during the thermoplastic connection process, which brings certain difficulties to the processing and positioning of the soft mouth tubes 11', 12', which not only reduces the processing efficiency, but also affects the processing quality, making the soft mouth tubes 11', 12' The tightness of the connection between ' and the bag body 1' is not guaranteed

[0004] In addition, each soft mouth tube 11', 12' is sealed and connected to the bag body 1' through the outer circular side wall at its tail end. The sealing performance of this large-angle steering connection method is relatively poor. There is a connection dead angle at the connection and closure, and it often occurs that the soft mouth tube 11', 12' and the bag body 1' are not completely sealed, resulting in liquid leakage

[0005] Furthermore, because the break valve 2' needs to break off the mouth 21' before use, this structure makes the material constituting the break valve 2' have a certain degree of brittleness. In the existing structure, the break valve 2' is generally made of hard material. , which is completely different from the material of the infusion port tube, the two are set separately and connected with the infusion port tube sleeve through the connection hole 22' at the end of the break valve 2'. This connection method makes the break valve 2' and the infusion port There is a connecting sealing surface between the tubes, which has a potential safety hazard of leakage
