Description

Technical Field

[0001] This utility model belongs to the field of oxygen flow meter disassembly, and specifically relates to a disassembly device for an oxygen flow meter in a central oxygen supply system. Background Technology

[0002] The oxygen flow meter in a central oxygen supply system is a key device for accurately monitoring and adjusting the oxygen output flow rate. It is typically installed between the oxygen supply terminal and the oxygen inhalation device. It displays the oxygen flow rate visually through a dial or digital display. Medical staff can adjust the flow rate by turning the control knob to change the valve opening degree according to the patient's condition, ensuring that the oxygen supply meets the treatment needs.

[0003] However, the existing oxygen flow meters in central oxygen supply systems are particularly inconvenient to disassemble. The operation requires applying a certain amount of force to press the interface, which not only increases the physical exertion of medical staff, but may also cause wear or deformation of the interface due to uneven force, affecting the sealing of subsequent connections. During manual disassembly, air or contaminants can easily get into the interface, posing a risk of oxygen source contamination. Especially in emergency situations, the time-consuming disassembly may delay oxygen supply to patients, and improper disassembly may also cause instantaneous oxygen leakage, posing a safety hazard. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a device for disassembling an oxygen flow meter for a central oxygen supply system, so as to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A device for disassembling an oxygen flow meter for a central oxygen supply system includes a mounting base. A first disassembly rod is fixedly connected to the outer side of the mounting base, and a second disassembly rod is fixedly connected to the inner side of the mounting base. Both the first and second disassembly rods include a pressure rod. An insertion rod is fixedly connected to the other end of the pressure rod. An extension head is fixedly connected to the upper surface of the end of the insertion rod, and a pry seat is fixedly connected to the lower surface of the end of the insertion rod.

[0007] As a preferred technical solution, the mounting base includes an outer shell, the first disassembly rod is fixedly connected to the outer shell, a central rod is fixedly connected inside the outer shell, an inner seat is sleeved on the outer surface of the central rod, a sliding hole is opened on the surface of the outer shell, and the outer side of the inner seat is fixedly connected to the second disassembly rod through the sliding hole.

[0008] As a preferred technical solution, the outer surface of the outer shell is provided with a fixing screw hole, the fixing screw hole is internally threaded with a fixing screw rod, the fixing screw rod is movably connected to the inner seat, and the other end of the fixing screw rod is fixedly connected to a rotating handle.

[0009] As a preferred technical solution, both sides of the first disassembly rod and the second disassembly rod are fixedly connected to connecting plates. The surface of each connecting plate is provided with a fixing through hole, and a fixing screw is inserted into the inside of each fixing through hole. The fixing screw passes through the fixing through hole and is threadedly connected to the outer shell and the inner seat.

[0010] As a preferred technical solution, a protective pad is fixedly connected to the outer surface of the pressure rod, and the protective pad covers the pressure rod. Rubber pads are fixedly connected to the outer surfaces of the insertion rod, the extension head, and the prying seat, and the rubber pads cover the insertion rod, the extension head, and the prying seat.

[0011] In summary, the present invention has the following main advantages:

[0012] First, when using the device, insert the insertion rods of the first and second disassembly rods into both sides of the connector. At this time, the extension head is connected to one side of the connector, while the prying seat is connected to the other side of the connector. Then, the pressure rod can be moved downwards. Under the action of the lever principle, the oxygen flow meter can be easily disassembled. This disassembly method does not require manual pressing of the interface. It saves effort and is efficient through the lever action, which can avoid wear and deformation of the interface caused by uneven force, ensure the sealing of subsequent connections, reduce the direct wear of components by manual operation, reduce the risk of oxygen leakage, and is simple and easy to operate. Even novices can quickly master it. Especially in the scenario of frequent disassembly and maintenance, it can greatly improve work efficiency and meet the requirements of safe and efficient use of medical equipment.

[0013] Secondly, this utility model, through its mounting base, allows for the disassembly of different oxygen flow meters. By rotating the fixing screw, the inner base can rotate within the outer shell, while the second disassembly rod is fixedly connected to the inner base. The rotation of the inner base drives the second disassembly rod to move, thereby adjusting the angle between the first and second disassembly rods. This accommodates the disassembly of oxygen flow meters with different diameters. This structure allows for flexible angle adjustment, adapting to various specifications of oxygen flow meters. It eliminates the need for specialized disassembly tools for different diameter oxygen flow meters, reducing tool costs. Furthermore, the adjustment operation is simple, requiring only the rotation of the fixing screw, enabling rapid adaptation to different disassembly scenarios and improving the versatility and efficiency of disassembly.

[0019] Example

[0020] refer to Figures 1 to 4 This embodiment of an oxygen flow meter disassembly device for a central oxygen supply system includes a mounting base 1. A first disassembly rod 2 is fixedly connected to the outer side of the mounting base 1, and a second disassembly rod 3 is fixedly connected to the inner side of the mounting base 1. Both the first disassembly rod 2 and the second disassembly rod 3 include a pressure rod 31. An insertion rod 32 is fixedly connected to the other end of the pressure rod 31. An extension head 33 is fixedly connected to the upper surface of the end of the insertion rod 32, and a pry seat 34 is fixedly connected to the lower surface of the end of the insertion rod 32. The entire device is made of metal.

[0021] refer to Figures 1-4 The mounting base 1 includes an outer shell 111, a first disassembly rod 2 fixedly connected to the outer shell 111, a central rod 112 fixedly connected inside the outer shell 111, an inner seat 113 sleeved on the outer surface of the central rod 112, a sliding hole 114 opened on the surface of the outer shell 111, and the outer side of the inner seat 113 passing through the sliding hole 114 and fixedly connected to the second disassembly rod 3; because the inner seat 113 is rotatably connected to the outer shell 111, and the second disassembly rod 3 is fixedly connected to the inner seat 113, the second disassembly rod 3 can be moved by the rotation of the inner seat 113, thereby adjusting the angle between the first disassembly rod 2 and the second disassembly rod 3.

[0022] refer to Figure 2 The outer surface of the outer shell 111 is provided with a fixing screw hole 4. A fixing screw 5 is threaded into the fixing screw hole 4. The fixing screw 5 is movably connected to the inner seat 113. The other end of the fixing screw 5 is fixedly connected to a rotating handle 6. By turning the fixing screw 5, the fixing screw 5 is no longer in contact with the inner seat 113. At this time, the inner seat 113 can rotate. By turning the fixing screw 5 in the opposite direction, the fixing screw 5 is brought into contact with the inner seat 113, thereby fixing the inner seat 113 and preventing it from rotating again after adjustment.

[0023] refer to Figure 3Both sides of the first disassembly rod 2 and the second disassembly rod 3 are fixedly connected to connecting plates 9. The surface of the connecting plates 9 is provided with fixing through holes 10. Fixing screws 11 are inserted into the fixing through holes 10. The fixing screws 11 pass through the fixing through holes 10 and are threadedly connected to the outer shell 111 and the inner seat 113. The first disassembly rod 2 and the second disassembly rod 3 can be installed by the fixing screws 11 and the fixing through holes 10. The installation by the threaded connection is more convenient during disassembly.

[0024] refer to Figure 2 A protective pad 7 is fixedly connected to the outer surface of the pressure rod 31, which covers the pressure rod 31. Rubber pads 8 are fixedly connected to the outer surfaces of the insertion rod 32, extension head 33 and pry seat 34, which cover the insertion rod 32, extension head 33 and pry seat 34. The protective pad 7 can prevent hand injury when the pressure rod 31 is pressed down, and the rubber pad 8 can prevent sparks from being generated when metal comes into contact with each other.

[0025] Operating principle and advantages: First, by adjusting the angle between the first disassembly rod 2 and the second disassembly rod 3, the inner seat 113 can rotate inside the outer shell 111 by rotating the fixing screw 5. The second disassembly rod 3 is fixedly connected to the inner seat 113, so the rotation of the inner seat 113 can drive the second disassembly rod 3 to move, thereby adjusting the angle between the first disassembly rod 2 and the second disassembly rod 3. This can meet the disassembly and use of oxygen flow meters with different diameters. Then, the insertion rods 32 of the first disassembly rod 2 and the second disassembly rod 3 are inserted into both sides of the connector. At this time, the extension head 33 is connected to one side of the connector, and the pry seat 34 is connected to the other side of the connector. Then, the pressure rod 31 can be moved downwards. Under the action of the lever principle, the oxygen flow meter can be easily disassembled. This disassembly method does not require manual pressing of the interface. It is labor-saving and efficient through the lever action. The protective pad 7 can prevent hand injury when pressing the pressure rod 31 downwards, and the rubber pad 8 can prevent sparks that may occur when metal comes into contact with each other.
