Description

Technical Field

[0001] This application relates to the field of hospital gas pipelines, and more particularly to an oxygen transmission branch line adapter. Background Technology

[0002] Typically, gas pipelines consist of a main pipeline and branch pipelines. The main pipeline connects to the gas station to deliver oxygen to the wards on each floor via the branch pipelines. If the oxygen supply to the entire building malfunctions, it is usually due to a fault in the main pipeline. Repairing the main pipeline requires shutting down the gas station and stopping the oxygen supply to the floors, which disrupts the normal operation of the wards, especially severely impacting the use of intensive care units. Therefore, there is still room for improvement. Summary of the Invention

[0003] In order to facilitate maintaining oxygen supply to the floors during the maintenance of the main pipeline, this application provides an oxygen transmission branch pipeline conversion joint.

[0004] The oxygen transmission branch pipeline conversion joint provided in this application adopts the following technical solution:

[0005] An oxygen transmission branch line conversion connector includes an intermediate connecting pipe and a first connecting pipe and a second connecting pipe respectively disposed at both ends of the intermediate connecting pipe. The first connecting pipe is used to connect to the branch line, and the second connecting pipe is used to connect to a spare oxygen cylinder.

[0006] By adopting the above technical solution, when the main pipeline needs maintenance, the secondary pressure reducing valve is first removed and the first connecting pipe is connected to the branch pipeline of the corresponding floor. Then, the second connecting pipe is connected to the spare oxygen cylinder. Thus, while the main pipeline is being maintained, oxygen can be supplied normally to the wards on the corresponding floor through the oxygen cylinder.

[0007] Preferably, the first connecting pipe includes a first short pipe and a first right-angle connector. The first short pipe is connected to the intermediate connecting pipe through the first right-angle connector, and the first short pipe is used to connect to the branch pipe.

[0008] In practical applications, the valves on the gas supply branch pipelines on each floor are compactly arranged. By adopting the above technical solution, the first right-angle connector is used as the connecting component between the first short pipe and the intermediate connecting pipe, which realizes the turning purpose between the conversion joint and the branch pipeline. This allows the conversion joint to avoid the valves around the secondary pressure reducing valve, which is beneficial to improving the ease of disassembly and assembly of the conversion joint.

[0009] Preferably, the second connecting tube includes a second short tube, a second right-angle connector, and a size conversion head. One end of the second right-angle connector is connected to the middle connecting tube, and the other end of the second right-angle connector is connected to the second short tube through the size conversion head. The second short tube is used to connect to the oxygen cylinder.

[0010] In practical applications, oxygen cylinders have a small diameter. Therefore, by adopting the above technical solution, the second short tube is tightly connected to the oxygen cylinder through a size conversion head set at the port of the second right-angle connector. This helps to improve the applicability of the conversion head and thus ensures the normal oxygen supply to wards on each floor.

[0011] Preferably, the size conversion head includes a front threaded rod and a rear connecting cylinder connected to each other. The front threaded rod has a central hole extending through it along its own axis. The rear connecting cylinder has a through hole in the middle that communicates with the central hole. The second short tube communicates with the through hole.

[0012] By adopting the above technical solution, the size conversion head is divided into two parts: a front threaded rod and a rear connecting cylinder. A central hole and a through hole are opened inside each part to facilitate the connection of branch pipes and the second short pipe, which helps to improve the connection stability and connectivity.

[0013] Preferably, the outer circumferential surface of the second short tube is provided with external threads, and the inner wall of the through hole of the rear connecting cylinder is provided with internal threads, and the second short tube is threadedly connected to the through hole.

[0014] By adopting the above technical solution, the second short pipe is threaded into the through hole of the rear connecting cylinder, which helps to improve the connection stability between the second short pipe and the rear connecting cylinder.

[0015] Preferably, sealing rings are provided at the connection points between the first right-angle connector and the intermediate connecting pipe, and at the connection points between the second right-angle connector and the intermediate connecting pipe.

[0016] By adopting the above technical solution, the sealing ring is elastic, has appropriate mechanical strength, stable performance, does not corrode the contact surface, and does not contaminate the medium.

[0017] Preferably, a shut-off valve is provided at the intermediate connecting pipe.

[0018] By adopting the above technical solution, a shut-off valve is installed at the intermediate connecting pipe to control the opening or closing of the oxygen supply from the oxygen cylinder.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. When the main pipeline needs maintenance, first remove the secondary pressure reducing valve and connect the first connecting pipe to the branch pipeline of the corresponding floor. Then connect the second connecting pipe to the spare oxygen cylinder. This allows for the normal supply of oxygen to the wards on the corresponding floor through the oxygen cylinder while the main pipeline is being maintained.

[0021] 2. The first right-angle connector is used as the connecting component between the first short pipe and the intermediate connecting pipe, which realizes the turning purpose between the conversion joint and the branch pipe, so that the conversion joint can avoid the valves around the secondary pressure reducing valve, which is conducive to improving the ease of disassembly and assembly of the conversion joint;

[0022] 3. In use, the second short tube is tightly connected to the oxygen cylinder through the size conversion head set at the port of the second right-angle connector, which helps to improve the applicability of the conversion connector and thus ensures the normal oxygen supply to wards on each floor.

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] In practical applications, the gas supply pipeline for the entire building includes a main pipeline and branch pipelines. A primary pressure reducing valve is installed on the main pipeline, and branch pipelines connect to each floor of the building, each equipped with a secondary pressure reducing valve. During use, the primary pressure reducing valve reduces the oxygen pressure within the main pipeline. Then, as the oxygen enters the branch pipelines on each floor, the secondary pressure reducing valves further reduce the oxygen pressure, ensuring that the oxygen delivery pressure meets therapeutic requirements.

[0030] This application discloses an oxygen transmission branch pipeline conversion connector, referring to... Figure 1 and Figure 2 It includes an intermediate connecting pipe 1 and a first connecting pipe 2 and a second connecting pipe 3 respectively located at both ends of the intermediate connecting pipe 1, and the three are interconnected. The first connecting pipe 2 is used to connect to a branch line, and the second connecting pipe 3 is used to connect to a spare oxygen cylinder. A shut-off valve 5 is installed on the intermediate connecting pipe 1 to control the opening or closing of the oxygen supply from the oxygen cylinder.

[0031] In this embodiment, the first connecting pipe 2 includes a first short pipe 21 and a first right-angle connector 22, which are connected by threads. The first short pipe 21 is connected to the intermediate connecting pipe 1 through the first right-angle connector 22, and the first short pipe 21 is used to connect to the branch pipe.

[0032] The second connecting pipe 3 includes a second short pipe 31, a second right-angle connector 32, and a size conversion head 33. One end of the second right-angle connector 32 is connected to the middle connecting pipe 1, and the other end of the second right-angle connector is connected to the second short pipe 31 through the size conversion head 33. The second short pipe 31 is used to connect to the high-pressure hose of the oxygen cylinder.

[0033] In this embodiment, both the first short pipe 21 and the second short pipe 31 are horizontally arranged and extend in opposite directions under the 90º reversal action of the first right-angle connector 22 and the second right-angle connector 32, so that when the second connecting pipe 3 is connected to the branch pipe, it can avoid the valves around the secondary pressure reducing valve and facilitate connection with the oxygen cylinder.

[0034] Reference Figures 2 to 4 In this embodiment, the size conversion head 33 includes a front threaded rod and a rear connecting cylinder connected to each other. The rear connecting cylinder has a cylindrical structure that is larger at the top and smaller at the bottom. The front threaded rod has a central hole extending along its own axis, and the middle of the rear connecting cylinder has a through hole communicating with the central hole. The second short tube 31 communicates with the through hole to allow oxygen from the oxygen cylinder to pass through. The front threaded rod is threadedly connected to the second right-angle connector 32. The outer circumferential surface of the second short tube 31 is provided with external threads, and the inner wall of the through hole of the rear connecting cylinder is provided with internal threads. The second short tube 31 is threadedly connected to the through hole. In use, the second short tube 31 is tightly connected to the oxygen cylinder through the size conversion head 33 located at the port of the second right-angle connector 32 to ensure normal oxygen supply to wards on each floor. In use, the appropriate size conversion head 33 can be selected according to the diameter of the high-pressure hose of the oxygen cylinder.

[0035] In this embodiment, sealing rings are provided at the connection points of the first right-angle connector 22 and the intermediate connecting pipe 1, as well as at the connection points of the second right-angle connector 32 and the intermediate connecting pipe 1. The sealing rings are corrosion-resistant O-rings, which are elastic, have appropriate mechanical strength, stable performance, do not corrode the contact surfaces, and do not contaminate the medium. During installation, the sealing rings are placed smoothly on both sides of the right-angle connector's connection ports until they are fully fitted. The outer nut should be rotated slowly with a wrench; installation is simple and effortless.

[0036] The implementation principle of an oxygen transmission branch pipeline conversion joint in this application embodiment is as follows:

[0037] Step 1: Prepare oxygen cylinders for each floor. Select the corresponding first short tube 21 and size conversion head 33 according to the diameter of the oxygen cylinder, and then install the oxygen cylinder on each floor. The oxygen cylinder is connected to the second short tube 31 through the high-pressure hose 6 to supply oxygen to each floor.

[0038] Step 2: Close one of the secondary pressure reducing pipelines connected to the oxygen pressure reducing pipeline, then remove the secondary pressure reducing valves on each floor of this pipeline. Based on the diameter of the secondary pressure reducing valve, select the corresponding first short pipe 21, and then connect it to the branch pipeline through the first short pipe 21.

[0039] Step 3: Open shut-off valve 5 to supply oxygen to the gas-using equipment in each ward.

[0040] Step 4: Inspect the main inlet pipe and oxygen supply pipe before the secondary pressure reducing valve at the gas station.

[0041] After the maintenance is completed, shut off valve 5, then remove the second short pipe 31, install the secondary pressure reducing valve, open the secondary pressure reducing pipeline, and finally turn on the oxygen supply system of the gas station to supply oxygen to each floor.

[0042] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
