Description

Technical Field

[0001] This utility model relates to the field of manifolds, specifically to a medical oxygen concentrator and an automatic manifold switching device. Background Technology

[0002] Medical oxygen concentrators and manifolds are common devices in the medical field, especially in hospitals, clinics, and home care, where they help ensure patients have an adequate supply of oxygen. A manifold is a device used to connect multiple oxygen sources or pipelines to a single point, often used in environments requiring large oxygen supplies, such as hospitals. Its function is to ensure a stable oxygen flow. Manifolds allow for centralized management of multiple oxygen sources, preventing oxygen supply interruptions in the event of a single device failure.

[0003] In existing manifold designs, multiple valves are often included internally, which are used to distribute and regulate the direction and flow rate of fluids. However, in actual installation and maintenance, the manifold is usually integrated into a limited space, resulting in very little operating space, which poses a significant challenge to the maintenance and replacement of valves.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] First embodiment:

[0027] See Figures 1-4 As shown, this utility model provides an automatic switching device for a medical oxygen concentrator and a manifold, including a base plate 1, a sliding rod 2 connected to the top surface of the base plate 1, and four sliding rods 2, and also includes a base box 3, the bottom surface of the base box 3 is slidably engaged with the sliding rods 2, the base box 3 is a rectangular frame, and the four sliding rods 2 correspond to the four corners of the base box 3 respectively;

[0028] The upper surface of the base plate 1 is provided with a support platform 101 for supporting the base box 3. The support platform 101 is made of rubber and is truncated cone-shaped. The upper surface of the support platform 101 forms support for the base box 3. The rubber support platform 101 is elastic and can better support the base box 3.

[0029] The side wall of the bottom box 3 is rotatably connected to a side plate 4. The side plate 4 can rotate on the side wall of the bottom box 3. When the side plate 4 is rotated to a vertical state, multiple side plates 4 form a cylindrical structure in the vertical state. The movable end of the side plate 4 is provided with a fixing ring 401 corresponding to the sliding rod 2. It also includes a top cover 6 that is sealed with the cylindrical structure.

[0030] The top cover 6 is equipped with a touch screen 7, which can be used to display the screen. The bottom of the bottom box 3 is equipped with a cooling fan 8. The top cover 6 has multiple through holes. This design allows the top cover 6 to form an air intake channel when it is working, thereby accelerating the airflow speed inside the cylinder structure and improving the heat dissipation effect of the internal equipment.

[0031] Furthermore, the bottom box 3 is equipped with a support frame 9 located within the cylindrical structure. The support frame 9 is equipped with a controller 10 and a valve assembly 11, forming a mounting support for the controller 10 and the valve assembly 11. The bottom box 3 is connected to an inlet pipe and an outlet pipe with flow sensors on both sides. The flow sensors in the inlet pipe and the air storage tank can monitor the flow rate of the inlet and outlet air. The flow sensors are Emerson flow sensors, which can provide accurate data feedback and are suitable for use in automatic manifold switching systems. The valve assembly 11 includes two sets of control valve modules connected between the inlet pipe and the outlet pipe. Each valve module includes an electric throttle valve, a check valve, and a buffer arranged in series. The electric throttle valve controls the flow rate or pressure of the fluid and can finely adjust the operating conditions of the system, while the check valve ensures that the fluid can only flow in a predetermined direction to prevent backflow. At the same time, combined with the buffer, it helps to reduce the system impact caused by sudden changes in flow rate and ensures the stability of the delivery. Specifically, the support frame 9 includes multiple vertical rods, and a frame-shaped platform extending along the length of the vertical rods is connected to the outside of the vertical rods to assist in fixing the valve assembly 11; the connecting parts on the valve assembly 11 can be installed on the frame-shaped platform.

[0032] The air inlet pipe, valve group 11, and air outlet pipe are connected in series. The cooling fan 8, flow sensor, touch screen 7, and valve group 11 are all electrically connected to the controller 10. The controller 10 receives feedback from the flow sensor and controls the valve group 11 to control the flow. The results are displayed on the touch screen 7. When the equipment is working, the cooling fan 8 can be controlled to assist in the heat dissipation of the internal components of the equipment and improve the stability of the equipment.

[0033] When the device needs maintenance, pulling the bottom box 3 upward will disengage the high end of the sliding rod 2 from the fixed ring 401, thus releasing the restriction on the fixed ring 401. The support frame 9 can be fully exposed by rotating the side plate 4, which facilitates maintenance operations on the components on the support frame 9 and greatly improves the convenience of using the equipment. Furthermore, the upper surface of the bottom plate 1 is provided with a cylinder 5 to push the bottom box 3 upward, so that the bottom box 3 can be pushed upward by the cylinder 5.

[0034] The second embodiment differs from the first embodiment in that:

[0035] The top cover 6 has a through hole corresponding to the sliding rod 2. The high end of the sliding rod 2 protrudes from the top cover 6 and is threaded with a fixing nut. After the top cover 6 is installed on the high end of the side plate 4, the high end of the sliding rod 2 protrudes from the through hole on the top cover 6 and can be installed on the high end of the sliding rod 2 by the fixing nut, thereby locking the top cover 6 and improving the overall fixation of the device. Furthermore, the bottom box 3 is provided with a rubber sliding sleeve that slides with the sliding rod 2, which assists in the sliding of the sliding rod 2 and the bottom box 3.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
