Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically a medical oxygen pipeline connection device. Background Technology
[0002] Medical oxygen pipelines are an important system in hospitals for delivering medical oxygen. They need to meet strict safety and hygiene standards to ensure patient safety. Medical oxygen pipelines are generally made of stainless steel because stainless steel has good corrosion resistance and oxidation resistance, which can ensure the purity of oxygen. During the laying process, if the length of the pipeline is insufficient, the ends of the two pipelines need to be connected.
[0003] Currently, when connecting two pipes, a connector is usually used. However, the connector connects the two pipes at both ends by threading them together and then using a sealing gasket. Therefore, the sealing performance between the pipes and the connector is mainly related to the tightness of the thread engagement. However, the thread is prone to jamming during engagement, which can lead to thread stripping. Stripped threads cannot allow the sealing gasket to seal the pipes and connectors, thus causing air leakage. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0025] Please refer to Figures 1-5 In the embodiments of the utility model, a medical oxygen pipeline connecting device comprises a connecting pipe 1, an air outlet mechanism 2 and a fastening mechanism 3, both ends of the connecting pipe 1 are fixedly connected with two silica gel rings 11, the inner ring edges of the two silica gel rings 11 at the same end of the connecting pipe 1 are both provided with chamfers, the air bag 12 of annular structure and fixedly connected with the inner wall of the connecting pipe 1 is clamped between the two silica gel rings 11 at the same end of the connecting pipe 1, the air cock 13 fixedly penetrating the connecting pipe 1 is fixedly penetrated on the outside of the air bag 12, the connecting pipe 1 is internally provided with two symmetrical air outlet mechanisms 2, which can make the connecting pipe 1 communicate with the interiors of two pipelines, and both ends of the connecting pipe 1 are provided with fastening mechanisms 3, which can fix the pipelines at the end portions of the connecting pipe 1.
[0026] Specifically, first, one end of the pipeline is inserted into one end of the connecting pipe 1 by force until the one end of the pipeline pushes open the air outlet mechanism 2 at the corresponding position, so that the interior of the pipeline communicates with the interior of the connecting pipe 1, then the air bag 12 at the corresponding position is inflated to make the air bag 12 swell until the inner wall of the air bag 12 tightly fits the outer wall of the pipeline, so that the sealing property between the connecting pipe 1 and the pipeline can be increased, the inflated air bag 12 can fix the pipeline, and the stability between the pipeline and the connecting pipe 1 is increased, then the end portion of the connecting pipe 1 is plugged by the fastening mechanism 3 at the corresponding position, the fastening mechanism 3 can stably fix the end portion of the pipeline in the interior of the connecting pipe 1, then the other pipeline is inserted into the interior of the connecting pipe 1 and fixed by the same method.
[0027] Example 1
[0028] like Figure 3 As shown, in this embodiment, two symmetrical fixing plates 14 are fixedly connected inside the connecting pipe 1. Multiple through holes 15 are opened through the side of the fixing plate 14 at equal angles. The air outlet mechanism 2 includes a movable plate 21 that slides inside the connecting pipe 1. Multiple air outlet holes 22 are opened through the side of the movable plate 21 at equal angles. A plug 23 is fixedly connected to the side of the movable plate 21 corresponding to the through hole 15 and inserted through the through hole 15 at the corresponding position. A connecting rod 24 is fixedly connected to the side of the movable plate 21 and slides through the fixing plate 14 at the corresponding position. A mesh plate 26 is fixedly connected to one end of the connecting rod 24. A spring 25 is fixedly connected between the movable plate 21 and the fixing plate 14 at the corresponding position and located outside the connecting rod 24. The diameter of the mesh plate 26 and the movable plate 21 is the same as the inner diameter of the connecting pipe 1. Sealing gaskets are fixedly connected to the outer walls of the mesh plate 26, the movable plate 21 and the plug 23.
[0029] In this embodiment, when the pipe is inserted into the connecting pipe 1, the end of the pipe can push the mesh plate 26 at the corresponding position towards the middle of the connecting pipe 1. The moving mesh plate 26 can drive the moving plate 21 at the corresponding position through the connecting rod 24 at the corresponding position, thereby disengaging the multiple plugs 23 at the corresponding position from the through holes 15 at the corresponding position. This allows the middle and both ends of the connecting pipe 1 to be connected through the multiple through holes 15 and the multiple air outlets 22, thereby allowing the two conduits to be connected to the inside of the connecting pipe 1 so that oxygen can flow normally.

Both ends of the outer wall of the connecting pipe 1 are provided with external threads 16. The inner wall of the fixing ring 31 is provided with internal threads 34 that are screwed into the external threads 16 at corresponding positions. The outer wall of the fixing ring 31 is fixedly connected with a hexagonal block 32. The inner edge of the silicone ring 11 near the end of the connecting pipe 1 is provided with a chamfer. The cross-section of the fastening block 33 is triangular and the fastening block 33 is made of silicone.
[0032] In the embodiment, the plurality of fastening blocks 33 can be clamped into the chamfers of the silica gel ring 11 at the corresponding positions by screwing the internal thread 34 with the external thread 16 at the corresponding positions, and since the cross section of the fastening block 33 is in a triangular structure, the plurality of fastening blocks 33 can tightly fix the pipe at the end of the connecting pipe 1 with the screwing of the external thread 16 and the internal thread 34.
