[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1

[0041] A medical oxygen concentration detection device includes an oxygen tank 1, a terminal plug 11 fixed to the top of the oxygen tank 1, and an oxygen meter 2 disposed at the output end of the terminal plug 11.

[0042] In this implementation plan: When measuring oxygen concentration, the oxygen meter needs to be connected to the terminal of the medical central oxygen supply system. Currently, the central oxygen supply system terminals used in hospitals are of different styles, and it is impossible to adapt the connection of the oxygen meter to different terminals. This results in the need to use different plugs for conversion before connecting the oxygen meter for measurement, causing many difficulties in the connection and causing great inconvenience to the testing personnel. To solve this technical problem, a docking mechanism 3 has been added to this application document.

[0043] like Figures 1-14 As shown:

[0044] In conjunction with the above, in order to adapt the connection of the oxygen meter 2 to different specifications of the terminal plug 11 and improve the convenience of the connection process between the terminal plug 11 and the oxygen meter 2, a docking mechanism 3 is also included, which is installed between the terminal plug 11 and the oxygen meter 2. The docking mechanism 3 includes a connecting component 31, a sealing component 32 and a reset component 33. The connecting component 31 is installed at the output end of the terminal plug 11, the sealing component 32 is installed at the end of the oxygen meter 2 near the terminal plug 11, and the reset component 33 is installed inside the connecting component 31.

[0045] In this implementation scheme: the connecting component 31 allows for the adaptation of different specifications of terminal plugs 11 to the connection of the oxygen meter 2, eliminating the need for conversion between different terminal plugs 11 before connecting the oxygen meter 2 for measurement, thus improving the convenience of the connection process between the terminal plug 11 and the oxygen meter 2 and making it easy to use. The sealing component 32 fills the gap between the outlet pipe 313 and the inlet pipe 322, improving the sealing effect and preventing gas leakage during the detection process from causing deviations in the detection results, thereby improving the accuracy of the detection. The reset component 33 enables quick and convenient separation and disassembly between the connecting plug 311 and the docking cover 321, facilitating the installation and disassembly of the oxygen meter 2 and the terminal plug 11, greatly saving installation and disassembly time, making it easier for testing personnel to install and replace, saving manpower, and providing good performance.

[0046] Furthermore:

[0047] In conjunction with the above, to adapt the connection of the oxygen meter 2 to different specifications of the terminal plug 11, a connection component 31 is also included. The connection component 31 includes a connection plug 311, an expansion support plate 312, a docking outlet pipe 313, a hinge seat 314, a push-pull connecting rod 315, an expansion connecting rod 316, a positioning slide rod 317, and a connection seat 318. The connection plug 311 is fixed at the end of the terminal plug 11 away from the oxygen tank 1. The interior of the connection plug 311 has several sets of expansion supports arranged in a circular array. The plate 312 and the connector 311 are provided with a connecting air pipe 313 inside. Several sets of hinge seats 314 are fixed on the surface of the connecting air pipe 313 near the side of the multiple sets of expansion support plates 312. The hinge seat 314 is hinged with an L-shaped push-pull connecting rod 315 inside. Expansion connecting rods 316 are symmetrically arranged on both sides of the push-pull connecting rod 315. A positioning slide rod 317 is fixed at one end of the expansion connecting rod 316. A connecting seat 318 is fixed on the side of the expansion support plate 312 near the hinge seat 314.

[0048] In this implementation plan: When using the medical oxygen concentration detection device, first align the docking cover 321 fixed on one side of the oxygen meter 2 with the connector 311. Then, push the oxygen meter 2 to move the docking cover 321 closer to the connector 311. As the docking cover 321 moves, it moves the inlet pipe 322 closer to the outlet pipe 313. When the inlet pipe 322 contacts the outlet pipe 313, as the docking cover 321 continues to move, it moves the inlet pipe 322 over the surface of the outlet pipe 313 and pushes the outlet pipe 313 towards the terminal connector 11. The movement of the outlet pipe 313 moves the hinge seat 314 synchronously, which in turn moves the push-pull linkage 315. The movement of the expansion linkage 316 causes it to rotate, which in turn causes the positioning slide rod 317 to slide inside the connecting seat 318. This pushes the connecting seat 318 out of the connecting plug 311. The movement of the connecting seat 318 then causes the expansion support plate 312 to move synchronously and expand outward from the inside of the connecting plug 311 until the surface of the expansion support plate 312 is in close contact with the inner wall of the docking cover 321. This completes the docking between the connecting plug 311 and the docking cover 321, enabling quick connection between the terminal plug 11 and the oxygen meter 2. It can adapt to different specifications of terminal plug 11 to connect the oxygen meter 2, eliminating the need to use different terminal plug 11 for conversion before connecting the oxygen meter 2 for measurement. This improves the convenience of the connection process between the terminal plug 11 and the oxygen meter 2, making it easy to use.

[0049] In an optional embodiment: the end of the expansion link 316 away from the positioning slide rod 317 is hinged to a fixing rod 3161, the end of the fixing rod 3161 away from the expansion link 316 is fixedly connected to the inner wall of the connector plug 311, the inside of the connector seat 318 near the fixing rod 3161 is provided with a relief groove 3162 adapted to the fixing rod 3161, the inside of the connector plug 311 near the expansion support plate 312 is provided with a clearance groove, the connecting air pipe 313 is composed of two pipes with different diameters, the inside of the connector seat 318 near the two sets of positioning slide rods 317 is provided with a positioning groove 3171 adapted to the positioning slide rod 317, the positioning slide rod 317 and the connector seat 318 are slidably connected through the positioning groove 3171, the end of the push-pull link 315 away from the hinge seat 314 is hinged to a hinge rod 3151, and the two ends of the hinge rod 3151 are fixedly connected to the two sets of expansion links 316 respectively.

[0050] In this implementation scheme: As the push-pull linkage 315 moves, with the cooperation of the hinge rod 3151, the expansion linkage 316 can be driven to make a circular motion with the fixed rod 3161 as the center and its own length as the radius. This can drive the positioning slide rod 317 to slide in the positioning slide groove 3171 opened inside the connecting seat 318, thereby pushing the connecting seat 318 to extend out of the connecting plug 311. With the cooperation of the avoidance groove 3162, after the connecting seat 318 is stored inside the connecting plug 311, it can avoid the position of the fixed rod 3161, preventing the connecting seat 318 from obstructing the fixed rod 3161. The surface of the connecting air pipe 313 is also provided with an avoidance rod groove that matches the push-pull linkage 315, thereby ensuring the smooth movement of the push-pull linkage 315 between the hinge seat 314 and the expansion linkage 316.

[0051] Furthermore:

[0052] In conjunction with the above, to prevent gas leakage during the testing process from causing deviations in the test results, a sealing assembly 32 is also included. The sealing assembly 32 includes a docking cover 321, a docking inlet pipe 322, a sealing ring 323, and a spring A324. A hollow docking cover 321 is fixed to one end of the oxygen meter 2 near the connector 311. The docking inlet pipe 322 is fixed inside the docking cover 321, and a sealing ring 323 is disposed inside the docking inlet pipe 322. The sealing ring 323 is located on the side away from the connector 311. A number of springs A324 arranged in a ring are fixed. A receiving groove 325 adapted to spring A324 is opened inside the inlet pipe 322 near the spring A324. Spring A324 is fixedly connected to inlet pipe 322 through receiving groove 325. Inlet cover 321 and oxygen meter 2 are connected through inlet pipe 322. Inlet pipe 322 is provided with a docking groove adapted to outlet pipe 313 at one end near outlet pipe 313, and sealing ring 323 is set in this docking groove.

[0053] In this implementation scheme: As the inlet pipe 322 moves, when the outlet pipe 313 is inserted into the groove inside the inlet pipe 322, it first contacts the sealing ring 323, compressing the sealing ring 323 and causing the spring A324 to deform and generate elastic force. This forces the spring A324 into the receiving groove 325. When the spring A324 is fully retracted into the receiving groove 325, the sealing ring 323 is positioned between the outlet pipe 313 and the inlet pipe 322. The compressive force between the outlet pipe 313 and the inlet pipe 322 causes the sealing ring 323 to deform, thereby filling the gap between the inlet pipe 313 and the outlet pipe 322. The gap between the outlet pipe 313 and the inlet pipe 322 improves the sealing effect and prevents gas leakage during the test, which could lead to deviations in the test results and thus improve the accuracy of the test. When the inlet pipe 322 and the outlet pipe 313 are separated, the sealing ring 323 can be pushed back to its initial position with the help of the spring A324. This prevents the sealing ring 323 from being pressed for too long and becoming stuck inside the inlet pipe 322, making it impossible to return to its original state. This ensures that the sealing ring 323 can immediately return to its original state when the inlet pipe 322 and the outlet pipe 313 are separated, thus avoiding affecting the next use.

[0054] Furthermore:

[0055] In conjunction with the above, to facilitate the installation and disassembly of the oxygen meter 2 and the terminal plug 11, a reset assembly 33 is also included. The reset assembly 33 includes a strong magnetic base A331, a strong magnetic base B332, a spring B334, and a locking bolt 335. A ring-shaped strong magnetic base B332 is fitted onto the surface of the connector 311 near the terminal plug 11, and the strong magnetic base B332 is slidably connected to the surface of the connector 311. A ring-shaped strong magnetic base A331 is fixed to the surface of the mating cover 321 near the strong magnetic base B332, connecting the mating outlet... A spring B334 is wound around the thinner end of the air tube 313. A receiving groove 333 adapted to the spring B334 is opened inside the thicker end of the connecting air tube 313. A locking bolt 335 is internally threaded to the strong magnetic suction seat B332, and one end of the locking bolt 335 abuts against the surface of the connecting plug 311. A sliding groove adapted to the connecting air tube 313 is opened inside the connecting plug 311. The connecting air tube 313 and the connecting plug 311 are slidably connected through this sliding groove, and the connecting plug 311 and the terminal plug 11 are connected through the connecting air tube 313.

[0056] In this implementation scheme: As the docking cover 321 moves, it can drive the strong magnetic chuck A331 to move synchronously and approach one end of the strong magnetic chuck B332. When the strong magnetic chuck A331 and the strong magnetic chuck B332 attract each other, the movement of the docking cover 321 and the strong magnetic chuck A331 can push the strong magnetic chuck B332 to slide on the surface of the connector 311. Furthermore, through the movement of the docking vent pipe 313, in cooperation with the receiving groove 333, the spring B3 can be compressed. 34 deforms and generates elastic force. After the connection between the connector 311 and the mating cover 321 is completed, the locking bolt 335 is tightened to secure the strong magnetic base B332 to the surface of the connector 311. Because the magnetic attraction force between the strong magnetic base A331 and the strong magnetic base B332 is much greater than the elastic force generated by the compression of the spring B334, the mating cover 321 can be secured by the cooperation of the strong magnetic base A331 and the strong magnetic base B332. 1. Fixed to the surface of the connector 311, thereby improving the firmness of the connection between the connector 311 and the docking cover 321. When it is necessary to disassemble the docking cover 321 and the connector 311, the locking bolt 335 can be turned in the opposite direction to release the lock between the strong magnetic base B332 and the connector 311. Then, by the rebound force of the spring B334, the docking outlet pipe 313 can be pushed to move in the opposite direction inside the connector 311, so that the multiple sets of expansion support plates 312 can be retracted into the interior of the connector 311. As the docking outlet pipe 313 moves, the docking inlet pipe 322 can be pushed to move the docking cover 321 on the surface of the connector 311. This allows for quick and convenient separation and disassembly of the connector 311 and the docking cover 321, facilitating the installation and disassembly of the oxygen meter 2 and the terminal plug 11, greatly saving installation and disassembly time, making it easier for testing personnel to install and replace, saving manpower, and providing good performance.

[0057] The working principle and usage process of this invention: When using this medical oxygen concentration detection device, first align the docking cover 321 fixed on one side of the oxygen meter 2 with the connector 311. Then, push the oxygen meter 2 to move the docking cover 321 closer to the connector 311. As the docking cover 321 moves, it moves the connecting air inlet pipe 322 closer to the connecting air outlet pipe 313. When the connecting air inlet pipe 322 contacts the connecting air outlet pipe 313, as the docking cover 321 continues to move, it causes the connecting air inlet pipe 322 to cover the surface of the connecting air outlet pipe 313, and pushes the connecting air outlet pipe 313 towards the terminal connector 11. The movement of the connecting air outlet pipe 313 synchronously drives the hinge seat 314. The movement of the push-pull linkage 315, in turn, causes the expansion linkage 316 to move in a circle with the fixed rod 3161 as the center and its own length as the radius. This causes the positioning slide rod 317 to slide within the positioning groove 3171 inside the connector 318, thus pushing the connector 318 out of the connector plug 311. The movement of the connector 318 then causes the expansion support plate 312 to move synchronously and expand outward from the inside of the connector plug 311 until the surface of the expansion support plate 312 is in close contact with the inner wall of the docking cover 321. This completes the docking between the connector plug 311 and the docking cover 321, enabling rapid connection of the terminal plug 11. The connection between the terminal plug 11 and the oxygen meter 2 is made compatible with different specifications of the terminal plug 11, eliminating the need for conversion between different terminal plugs 11 before connecting to the oxygen meter 2 for measurement. This improves the convenience of the connection process between the terminal plug 11 and the oxygen meter 2, making it easy to use. During this process, as the connecting air inlet pipe 322 moves, when the connecting air outlet pipe 313 is inserted into the connecting groove inside the connecting air inlet pipe 322, it will first come into contact with the sealing ring 323, and squeeze the sealing ring 323 to push the spring A324 to deform and generate elastic force, thereby squeezing the spring A324 into the receiving groove 325. When the spring A324 is completely retracted into the receiving groove 325, the sealing ring 323 is just clamped in the connecting air outlet. Between pipe 313 and the connecting inlet pipe 322, the squeezing force between the connecting outlet pipe 313 and the connecting inlet pipe 322 causes the sealing ring 323 to deform, thereby filling the gap between the connecting outlet pipe 313 and the connecting inlet pipe 322, improving the sealing effect, preventing gas leakage during the detection process from causing deviations in the detection results, and thus improving the accuracy of the detection. During this period, as the docking cover 321 moves, it can drive the strong magnetic chuck A331 to move synchronously and move closer to one end of the strong magnetic chuck B332. When the strong magnetic chuck A331 and the strong magnetic chuck B332 attract each other, the movement of the docking cover 321 and the strong magnetic chuck A331 can push the strong magnetic chuck B332 to slide on the surface of the connector 311.Furthermore, by moving the outlet pipe 313, and with the cooperation of the receiving groove 333, the spring B334 can be compressed to deform and generate elastic force. After the docking between the connector 311 and the docking cover 321 is completed, the locking bolt 335 can be tightened to firmly lock the strong magnetic base B332 onto the surface of the connector 311. Because the magnetic attraction force between the strong magnetic base A331 and the strong magnetic base B332 is much greater than the elastic force generated by the spring B334 after compression, the docking cover 321 can be fixed to the surface of the connector 311 by the cooperation of the strong magnetic base A331 and the strong magnetic base B332, thereby improving the firmness of the docking between the connector 311 and the docking cover 321. When it is necessary to dock the cover 321 and the connector 311... During disassembly, the locking bolt 335 is turned in the opposite direction to release the lock between the strong magnetic base B332 and the connector 311. Then, the spring force of the spring B334 pushes the connecting outlet pipe 313 to move in the opposite direction inside the connector 311, thus retracting the multiple sets of expansion plates 312 into the connector 311. As the connecting outlet pipe 313 moves, it pushes the connecting inlet pipe 322, causing the connecting cover 321 to move on the surface of the connector 311. This allows for quick and convenient separation and disassembly of the connector 311 and the connecting cover 321, facilitating the installation and disassembly of the oxygen meter 2 and the terminal plug 11. This significantly saves installation and disassembly time, making installation and replacement easier for testing personnel, reducing manpower costs, and providing excellent performance.
