Description
Technical Field
[0001] This utility model belongs to the technical field of medical oxygen supply equipment, specifically relating to a medical oxygen manifold. Background Technology
[0002] A medical oxygen manifold is a device that connects multiple oxygen storage cylinders to provide centralized oxygen supply. It is a core gas supply device in medical oxygen supply systems, used to improve the efficiency of central oxygen supply systems. The main function of a medical oxygen manifold is to connect multiple high-pressure oxygen cylinders in parallel and ensure the continuity, stability, and safety of oxygen supply through an automatic switching device. It is widely used in oxygen supply systems of various medium and large hospitals.
[0003] Currently, most existing medical oxygen manifolds adopt [the following design / method]. For example, patent application "202120291567.4" describes an automatic switching device for high-pressure medical oxygen manifolds, including a first manifold and a second manifold. The manifolds are connected to a pressure reducing valve via pipes, and the pressure reducing valve is connected to a manual shut-off valve and a pneumatic valve via pipes. When the oxygen cylinder in the manifold is insufficient, the pneumatic valve is opened, switching to the other manifold without interrupting the oxygen supply, thus avoiding interruptions in the medical oxygen supply. Another example is patent application "202321421783.1," which describes a multifunctional oxygen manifold, including a moving component, an oxygen supply component, and a push rod component. A buffer plate can block the oxygen manifolds on both sides, improving the buffering effect, while the moving component facilitates the overall transport of the manifold. However, existing medical oxygen manifolds often require manual switching to replace oxygen cylinders, posing a risk of oxygen supply interruption. Furthermore, the manifolds suffer from uneven pressure and flow distribution of medical oxygen across different departments, and there is a lack of rapid and effective methods for sampling the purity of oxygen within the pipeline. Therefore, the existing medical oxygen manifold structure needs further improvement. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a medical oxygen manifold with features such as compact structure, continuous and stable oxygen supply, good supply effect for multiple departments, and convenient oxygen purity detection. It can be widely used in the field of medical oxygen supply technology in various medium and large hospitals.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a medical oxygen manifold, comprising a base plate, on which two rows of oxygen cylinders are distributed on both sides, each row of oxygen cylinders being connected in series; each oxygen cylinder is equipped with a manual ball valve on its top, the manual ball valve being connected to a high-pressure hose, the high-pressure hose being equipped with a branch high-pressure valve, the branch high-pressure valve being connected to a branch outlet pipeline; a first main high-pressure valve and a second main high-pressure valve are provided at the rear end of the branch outlet pipeline, the first main high-pressure valve being equipped with an exhaust port at the rear end, and the second main high-pressure valve being connected to a control box at the rear end; a main outlet pipeline is provided at the top of the control box, and a gas distribution cylinder is provided at the rear end of the main outlet pipeline, the gas distribution cylinder being equipped with several gas distribution interfaces, through which medical oxygen is delivered to the gas-using terminals of various departments.

[0009] As an improvement, the second main high-pressure valve is an automatic regulating valve, which automatically controls the flow rate through the PLC inside the control box.
[0010] As an improvement, the control box is located in the middle of the two rows of oxygen cylinders and is symmetrically connected to the two rows of oxygen cylinders.
[0011] As an improvement, the control box is a first-level automatic switching control box, which is equipped with a PLC control system.
[0012] As an improvement, the gas distribution interface is provided with 3 to 10 ports, and a sampling bottle is provided on the pipeline at the rear end of the gas distribution interface.
[0013] As an improvement, the sampling bottles are located on each gas distribution interface and are equipped with a manual copper ball valve at the front end, which facilitates the sampling and testing of the purity of medical oxygen used in each department.
[0014] The beneficial effects of this utility model are as follows: A medical oxygen manifold features a compact structure, continuous and stable oxygen supply, good supply effect to multiple departments, and convenient oxygen purity testing. By adopting an automatic switching control box, the two rows of oxygen cylinders are automatically switched to prevent oxygen supply interruptions.

Detailed Implementation
[0017] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0018] like Figure 1 As shown, a medical oxygen manifold of this embodiment includes a base plate 1, on which two rows of oxygen cylinders 2 are distributed, and the oxygen cylinders 2 in each row are connected in series. Each oxygen cylinder 2 is equipped with a manual ball valve 3 on its top, which is connected to a high-pressure hose 4. The high-pressure hose 4 is equipped with a high-pressure branch valve 5, which is connected to a gas outlet pipeline 6. The gas outlet pipeline 6 is equipped with a first main high-pressure valve 7 and a second main high-pressure valve 8 at its rear end. The first main high-pressure valve 7 is equipped with an exhaust port 9 at its rear end, through which oxygen with unqualified purity or pressure is discharged. The second main high-pressure valve 8 is connected to a control box 10 at its rear end. The control box 10 is equipped with a main gas outlet pipeline 11 at its top, and a gas distribution cylinder 12 is equipped with a plurality of gas distribution interfaces 13, through which medical oxygen is delivered to the gas-using terminals of various departments.
[0019] Furthermore, the base plate 1 is provided with three side plates, covering the left side plate, the right side plate and the rear side plate, and the two rows of oxygen cylinders 2 are placed close to the left side plate and the right side plate respectively; specifically, the left side plate and the right side plate are fixedly connected to the base plate 1 by bolts.
[0020] Furthermore, the oxygen cylinders 2 are arranged in rows of 4 to 10, preferably 5 to 8, and both rows of oxygen cylinders are turned on simultaneously during operation. Specifically, when the supply flow of the oxygen cylinders 2 in the left row is insufficient, the control box 10 senses that the supply flow is lower than the set value through pressure detection and automatically starts the switching operation. The system controls the opening of the second main high-pressure valve 8 and the branch high-pressure valve 5 on the right side, and oxygen is supplied from the full oxygen cylinders 2 on the right side. At the same time, the second main high-pressure valve 8 on the left side is closed to replace the oxygen cylinders 2 in the left row.
[0021] Furthermore, both the sub-high pressure valve 5 and the first main high pressure valve 7 are automatic control valves, and their opening and closing are automatically controlled by the control box. Specifically, the sub-high pressure valve 5 enables the automatic switching operation of oxygen supply from the left and right oxygen cylinders, and the first main high pressure valve 7 enables the discharge of oxygen with unqualified purity or pressure.
[0022] Furthermore, the second main high-pressure valve 8 is an automatic regulating valve, which automatically controls the flow rate through the PLC inside the control box, thereby meeting the changing oxygen flow requirements at different times.
[0023] Furthermore, the control box 10 is located in the middle of the two rows of oxygen cylinders 2 and is symmetrically connected to the two rows of oxygen cylinders 2; specifically, the control box 10 is a first-level automatic switching control box, which is equipped with a PLC control system to control the automatic switching of the two rows of oxygen cylinders 2 and the amount of oxygen flow through the PLC control system.
[0024] Furthermore, the gas distribution interface 13 has 3 to 10, preferably 4 to 8, and 1 to 2 gas distribution interfaces can be reserved; a sampling bottle 14 is provided on the pipeline at the rear end of the gas distribution interface 13; specifically, the sampling bottle 14 is located on each gas distribution interface, and a manual copper ball valve 15 is provided at the front end, which controls the opening and closing, thereby facilitating the sampling and testing of the purity of medical oxygen used in each department.
[0025] This utility model of a medical oxygen manifold features a compact structure, continuous and stable oxygen supply, good multi-department supply effect, and convenient oxygen purity testing. Its main working process is as follows: First, replace all the full oxygen cylinders 2 in both rows and connect them to the high-pressure hose 4; then, fully open the manual ball valve 3 on the top of the oxygen cylinder 2. The control box 10 first starts the oxygen supply from the left oxygen cylinder, automatically opening the left-side high-pressure valve 5 and the second main high-pressure valve 8, thus beginning the supply of oxygen to the main outlet pipeline 11. The oxygen then flows through the main outlet pipeline 11 to the distribution cylinder 12, and then through the various distribution interfaces 13 on the distribution cylinder 12 to various departments in the hospital; when the left oxygen cylinder cannot meet the required flow rate... The control box 10 automatically switches to the right oxygen cylinder 2. The system automatically controls the opening of the right-side high-pressure valve 5 and the second main high-pressure valve 8, while simultaneously closing the left-side high-pressure valve 5 and the second main high-pressure valve 8. This facilitates the replacement of the left-side row of oxygen cylinders 2, ensuring a continuous and stable supply of medical oxygen to all departments of the hospital. In addition, when it is necessary to test whether the oxygen purity is up to standard, the manual copper ball valve 15 can be closed, the sampling bottle 14 can be removed, and the oxygen in the sampling bottle 14 can be tested. If the oxygen purity test fails, the first main high-pressure valve 7 can be opened, and the substandard oxygen can be discharged through the exhaust port 9. After the test is completed, the sampling bottle 14 can be reinstalled, and the manual ball valve 15 can be opened, greatly facilitating the sampling and testing of oxygen used in the pipeline.
[0026] Finally, it should be noted that the above examples are merely specific embodiments of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. All variations that can be directly derived or conceived by those skilled in the art from the disclosure of this utility model should be considered within the protection scope of this utility model.
