[0002] Respiratory medicine, as an important branch of the medical field, focuses on the research, diagnosis and treatment of respiratory diseases. Respiratory medicine mainly focuses on the health and disease management of the human respiratory system, including the physiological and pathological changes of tissue structures such as the nasal cavity, pharynx, trachea, bronchi, lungs and pleura.

[0003] In respiratory medicine, oxygen therapy is a common treatment method aimed at improving patients' respiratory function by providing them with additional oxygen. In the field of respiratory medicine, oxygen tubing connection devices are important medical devices to ensure that patients receive effective oxygen therapy.

[0004] An existing oxygen delivery tube connection device for respiratory medicine requires operators to connect the oxygen source to the nasal cannula using a connecting tube to form a complete oxygen delivery channel. However, the connecting tube needs to be cleaned after use to prevent cross-infection. But the existing oxygen delivery tube connection device does not allow operators to quickly connect and disconnect the oxygen delivery tube, which means that the oxygen delivery tube needs to be pulled forcefully each time it is disconnected, thus reducing the service life of the oxygen delivery tube.

[0005] Therefore, a connection device for oxygen delivery tubes in respiratory medicine is proposed. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: A fixing frame 11 is fixed on each side of the main body 1 of the connecting device. Two rotating plates 14 are movably installed inside the fixing frame 11. A locking plate 10 is fixed to one end of the rotating plate 14, and a first limiting block 6 is fixed to one side of the locking plate 10. Multiple spring-loaded telescopic rods 16 are hinged to both sides of the main body 1 of the connecting device. The top end of the spring-loaded telescopic rod 16 is hinged to one end of the rotating plate 14. A pressing rod 12 is hinged to one side of the rotating plate 14. One end of the pressing rod 12 extends out of the interior of the fixing frame 11. Two first fixing plates 4 are fixed to one side of the oxygen tube connecting seat 2, and two first fixing plates 4 are fixed to one side of the nasal tube connecting seat 8. A second fixing plate 15, a second limiting block 9 is fixed on one side of the first fixing plate 4 and the second fixing plate 15 respectively, a telescopic groove 5 is slidably installed inside the two sides of the connecting device body 1, a connecting plate 7 is fixed on one side of the telescopic groove 5, a supporting slide rod 21 is fixed on one side of the connecting plate 7, a limiting slide seat 18 is fixed on the outside of the connecting device body 1, the supporting slide rod 21 is slidably installed inside the limiting slide seat 18, a spring 17 is sleeved on the outside of the supporting slide rod 21, a tension spring 13 is fixed on the outside of the connecting device body 1, and one end of the tension spring 13 is fixedly connected to one side of the clamping plate 10.

[0021] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when connecting the oxygen tube connector 2 and the nasal cannula connector 8 using the main body 1 of the connecting device, the two first fixing plates 4 and the second fixing plate 15 fixed on one side of the oxygen tube connector 2 and the nasal cannula connector 8 can be inserted between the two clamping plates 10 installed on both sides of the main body 1 of the connecting device. Since a first limiting block 6 is fixed on one side of the clamping plate 10, and a second limiting block 9 is fixed on one side of each of the first fixing plate 4 and the second fixing plate 15, when the first fixing plate 4 and the second fixing plate 15 are inserted between the two clamping plates 10, The compression between the second limiting block 9 and the first limiting block 6 can cause the locking plate 10 to move, thereby locking the first limiting block 6 and the second limiting block 9 together. When the oxygen tube connector 2 and the nasal tube connector 8 are respectively locked on both sides of the connecting device body 1, one end of the oxygen tube connector 2 and the nasal tube connector 8 will respectively compress the connecting plates 7 that are slidably installed on both sides of the connecting device body 1, thereby causing the telescopic groove 5 fixed on one side of the connecting plate 7 to be housed inside the connecting device body 1. When the connecting plate 7 is compressed, the support slide rod 21 will be in the limiting position. The slide block 18 slides internally, simultaneously compressing the spring 17 sleeved on the outside of the support slide rod 21. When removing the oxygen tube connector 2 and the nasal tube connector 8, pressing the pressing rods 12 installed on both sides of the main body 1 of the connecting device can control one end of the locking plate 10 to tilt up. When one end of the locking plate 10 tilts up, it will pull the tension spring 13 and compress the rebound telescopic rod 16. When one end of the locking plate 10 tilts up, the first limiting block 6 will separate from the second limiting block 9. At this time, the pressure on the connecting plate 7 disappears, causing the compressed spring 17 to rebound, thereby locking the oxygen tube connector. The oxygen tube connector 2 and the nasal tube connector 8 pop out between the two retaining plates 10, which is very convenient. After the oxygen tube connector 2 and the nasal tube connector 8 are ejected from both sides of the main body 1 of the connecting device, the pressing of the pressing rod 12 is canceled. The tension spring 13 and the rebound of the rebound telescopic rod 16 can move one end of the retaining plate 10 back to its initial position, which facilitates the next installation and use. This device can realize the quick installation and removal of the oxygen tube, which is convenient for operators. Moreover, it will not damage the oxygen tube during the installation and removal process, thus improving the service life of the oxygen tube.

[0022] Example 2: The first fixing plate 4, the clamping plate 10 and the second fixing plate 15 are respectively arc-shaped, and the first limiting clamping block 6 and the second limiting clamping block 9 are used together. A sealing groove 20 is opened on one side of each of the two connecting plates 7, and a sealing gasket 19 is fixed on one side of each of the oxygen tube connecting seat 2 and the nasal tube connecting seat 8. The sealing gasket 19 is installed in conjunction with the sealing groove 20. A pipe 3 is fixed on one side of each of the oxygen tube connecting seat 2 and the nasal tube connecting seat 8, and the two pipes 3 are respectively connected to the interior of the connecting device body 1. The telescopic groove 5 is hollow cylindrical, and the two sides of the fixing frame 11 are open, and one end of the rotating plate 14 extends out of the interior of the fixing frame 11.

[0023] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, since a sealing gasket 19 is fixed on one side of the oxygen tube connector 2 and the nasal tube connector 8 respectively, and a sealing groove 20 is opened on one side of each of the two connecting plates 7, when the oxygen tube connector 2 and the nasal tube connector 8 squeeze the connecting plate 7, the sealing gasket 19 will be inserted into the sealing groove 20, thereby ensuring the seal and preventing oxygen leakage. Since the first fixing plate 4, the clamping plate 10 and the second fixing plate 15 are respectively arc-shaped, the stability of the connection between the oxygen tube connector 2 and the nasal tube connector 8 and the two ends of the connecting device body 1 can be improved.

[0024] Working principle: During connection, the two first fixing plates 4 and the second fixing plate 15, which are fixed on one side of the oxygen tube connector 2 and the nasal tube connector 8, are respectively inserted between the two clamping plates 10 installed on both sides of the main body 1 of the connecting device. After the first fixing plate 4 and the second fixing plate 15 are inserted between the two clamping plates 10, the clamping plates 10 can be moved by the compression between the second limiting block 9 and the first limiting block 6, thereby locking the first limiting block 6 and the second limiting block 9 into place. When the oxygen tube connector 2 and the nasal tube connector 8 are respectively locked on both sides of the main body 1 of the connecting device, one end of the oxygen tube connector 2 and the nasal tube connector 8 will respectively compress the connecting plates 7 that are slidably installed on both sides of the main body 1 of the connecting device, thereby fixing one side of the connecting plate 7. The telescopic groove 5 is housed inside the main body 1 of the connecting device. When the connecting plate 7 is compressed, the support slide rod 21 will slide inside the limiting slide seat 18, and at the same time, the spring 17 sleeved on the outside of the support slide rod 21 will be compressed. When the oxygen tube connector 2 and the nasal tube connector 8 are removed, the pressing rods 12 installed on both sides of the main body 1 of the connecting device can be pressed to control one end of the clamping plate 10 to tilt up. When one end of the clamping plate 10 tilts up, it will pull the tension spring 13 and compress the rebound telescopic rod 16. When one end of the clamping plate 10 tilts up, the first limiting block 6 will separate from the second limiting block 9. At this time, the pressure on the connecting plate 7 will disappear, and the compressed spring 17 will rebound, thereby popping the oxygen tube connector 2 and the nasal tube connector 8 out between the two clamping plates 10 respectively.
