Description

Technical Field

[0001] This invention relates to anti-detachment technology for anesthetic gas tubing, specifically to an anesthetic gas tubing with an anti-detachment structure. Background Technology

[0002] In the field of medical anesthesia, anesthetic gas tubing is one of the key pieces of equipment to ensure the smooth conduct of the anesthesia process. Its function is to accurately and stably deliver anesthetic gas from the anesthesia machine to terminal devices such as the oxygen mask used by the patient. However, existing anesthetic gas tubing has many problems that urgently need to be solved in practical applications, especially when connected to oxygen mask tubing.

[0003] Currently, the common connection method between anesthetic gas tubing and oxygen mask tubing is relatively simple, often using a direct plug-in connection. While this method is relatively easy to operate, it has poor stability. During anesthesia, the patient may generate external forces due to body movement, breathing, etc., which can easily cause the anesthetic gas tubing and oxygen mask tubing to loosen or even detach. Once the tubing detaches, the anesthetic gas cannot be delivered to the patient's body normally, which will seriously affect the anesthetic effect, leading to serious consequences such as the patient becoming aware of themselves during surgery, posing a great threat to the patient's life. At the same time, tubing detachment may also cause leakage of anesthetic gas, not only wasting medical resources but also polluting the operating room environment and increasing the risk of infection for medical staff.

[0004] In summary, existing anesthetic gas tubing has significant shortcomings in terms of connection stability, fixation and adjustment mechanisms, and resource utilization. There is an urgent need for a tubing with a reliable anti-detachment structure to meet the practical needs of modern medical anesthesia. This invention addresses these problems by researching and innovating to provide an anesthetic gas tubing with an anti-detachment structure, effectively solving the deficiencies in existing technologies, improving the safety and reliability of anesthetic gas tubing, and providing stronger support for medical anesthesia work. Summary of the Invention

[0005] The purpose of this invention is to provide an anesthetic gas tubing with an anti-detachment structure to solve the problem that in the prior art, anesthetic gas tubing is prone to loosening or detachment after connection, which leads to the inability of anesthetic gas to be delivered to the patient's body normally, seriously affecting the anesthetic effect, causing serious consequences such as the patient becoming aware during surgery, and posing a great threat to the patient's life safety.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an anesthetic gas pipeline with an anti-detachment structure, comprising a pipeline body, a connecting bend connected to the pipeline body, a connecting plate fixedly connected to one end of the connecting bend, an mounting ring connected to one side of the connecting plate, a functional cavity formed on the mounting ring, a plurality of transmission columns slidably connected within the functional cavity, a clamping block fixedly connected to one end of each transmission column, a first transmission inclined block fixedly connected to the other end of each transmission column, a first spring fixedly sleeved on the outer surface of each transmission column and fixedly connected to the first transmission inclined block, the other end of the first spring fixedly connected to the functional cavity, a second transmission inclined block slidably connected to one side of the first transmission inclined block, a first transmission plate slidably connected to the functional cavity fixedly connected to one side of the second transmission inclined block, a second spring fixedly connected to the functional cavity fixedly connected to one side of the first transmission plate, a pulling plate slidably connected to the mounting ring fixedly connected to the other side of the second transmission inclined block, and a pull ring fixedly connected to one end of the pulling plate;

[0007] The pull plate is provided with a locking mechanism, which is used to limit the pull plate.

[0008] Furthermore, the snap-fit ​​mechanism includes a snap-fit ​​groove on the pull plate, a snap-fit ​​block slidably connected in the snap-fit ​​groove, a pull column slidably connected to the mounting ring on one side of the snap-fit ​​block, a connecting block fixedly connected to one end of the pull column, a third spring fixedly sleeved on the outer surface of the pull column and fixedly connected to the connecting block, the other end of the third spring fixedly connected to the mounting ring, and a transmission mechanism connected to the mounting ring on the connecting block. The transmission mechanism is used to drive the pull column to move away from the center of the mounting ring.

[0009] Furthermore, the transmission mechanism includes a rotating ring rotatably connected to the mounting ring, the rotating ring having multiple arc-shaped grooves, and a sliding column slidably connected to the connecting block within the arc-shaped grooves.

[0010] Furthermore, the outer surface of the rotating ring is provided with friction texture.

[0011] Furthermore, the connecting plate is provided with a threaded groove, and the outer surface of the mounting ring is threadedly connected to the threaded groove via threads.

[0012] Furthermore, the clamping block is arc-shaped, and a rubber buffer pad is fixedly connected to one side of the clamping block.

[0013] Furthermore, a control valve is provided on the connecting bend.

[0014] Furthermore, two connecting sleeves are fixedly connected to the other end of the main pipeline body.

[0015] Compared with the prior art, the anesthetic gas tubing with an anti-detachment structure provided by the present invention has the following beneficial effects:

[0016] When connecting the bend to the oxygen mask tubing, pulling the pull ring activates a series of transmission components. Utilizing the different stiffness coefficients of the first and second springs, the clamping block moves flexibly. First, the second spring is stretched to move the clamping block away from the center of the mounting ring, facilitating insertion of the connecting tube. Releasing the pull ring causes the second spring to return to its original position, causing the clamping block to press against the connecting bend, ensuring a tight fit and effectively preventing the tubing from detaching. This significantly improves the stability of the anesthetic gas tubing connection, ensuring smooth and safe delivery of anesthetic gas.

[0017] The pull plate is limited by a snap-fit ​​mechanism. Before connecting the bend, rotating the rotating ring secures the pull plate, allowing medical personnel to accurately insert the bend into the connecting tube, making operation more convenient. After insertion, rotating the rotating ring again releases the limit, and the spring force automatically clamps and fixes the bend, enabling rapid connection and significantly saving operation time and improving work efficiency. Furthermore, the mounting ring and connecting plate are connected by threads. After use, the mounting ring can be unscrewed, disinfected, and reused, complying with the single-use standard for anesthetic gas tubing, reducing resource waste, and enhancing the product's economic and environmental benefits, demonstrating significant application value.

[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] Please see Figures 1 to 6 As shown, this invention provides an anesthetic gas pipeline with an anti-detachment structure, including a pipeline body 1, a connecting bend 2 connected to the pipeline body 1, a connecting plate 3 fixedly connected to one end of the connecting bend 2, a mounting ring 4 connected to one side of the connecting plate 3, a functional cavity 5 formed on the mounting ring 4, a plurality of transmission columns 6 slidably connected within the functional cavity 5, a clamping block 7 fixedly connected to one end of each transmission column 6, a first transmission inclined block 8 fixedly connected to the other end of each transmission column 6, and a first spring 9 fixedly sleeved on the outer surface of each transmission column 6 and fixedly connected to the first transmission inclined block 8. The other end of the spring 9 is fixedly connected to the functional cavity 5. The first transmission inclined block 8 is slidably connected to the second transmission inclined block 10. The second transmission inclined block 10 is fixedly connected to the first transmission plate 11, which is slidably connected to the functional cavity 5. The first transmission plate 11 is fixedly connected to the first spring 12, which is fixedly connected to the functional cavity 5. The other side of the second transmission inclined block 10 is fixedly connected to the pull plate 13, which is slidably connected to the mounting ring 4. One end of the pull plate 13 is fixedly connected to the pull ring 14. The stiffness coefficient of the first spring 9 is smaller than that of the second spring 12.

[0030] The pull plate 13 is provided with a locking mechanism, which is used to limit the pull plate 13.

[0031] The clamping block 7 is arc-shaped, and a rubber buffer pad is fixedly connected to one side of the clamping block 7. The rubber buffer pad buffers the clamping block 7 to prevent excessive clamping force from damaging the surface of the connecting bend 2 during the clamping process.

[0032] A control valve is installed on the connecting bend 2 to control the flow rate of the pipeline.

[0033] Two connecting sleeves are fixedly connected to the other end of the main pipe body 1, which facilitates the connection of the main pipe body 1.

[0034] When connecting the bend 2 to the pipe on the oxygen mask, the pull ring 14 moves the pull plate 13, which in turn moves the second transmission wedge 10. The second transmission wedge 10 moves the first transmission plate 11, which in turn moves the second spring 12. At this time, the transmission column 6 moves under the force of the first spring 9, causing the transmission column 6 and clamping block 7 to move away from the center of the mounting ring 4. Then, the connecting bend 2 is fitted onto the pipe on the oxygen mask, and the pull ring 14 is released. The second spring 12 then moves under its elastic force, causing the second transmission wedge 10 to move. The first transmission plate 11 and the second transmission inclined block 10 move, the second transmission inclined block 10 drives the first transmission inclined block 8 to move, the first transmission inclined block 8 drives the transmission column 6 to move, thereby causing multiple transmission columns 6 to drive the clamping block 7 to move, so that the clamping block 7 squeezes and clamps the connecting bend 2, the connecting bend 2 deforms under pressure, so that the connecting bend 2 and the connecting pipe inserted inside it are tightly fitted, thereby tightly fitting the connecting bend 2 to the connecting pipe on the oxygen mask, realizing the fastening connection of the connecting bend 2, effectively preventing the pipeline from falling off, and further improving the stability of the anesthetic gas pipeline connection.

[0035] Example 2

[0036] Based on Example 1, please refer to Figures 3 to 6 As shown, the snap-fit ​​mechanism includes a snap-fit ​​groove 21 on the pull plate 13, a snap-fit ​​block 22 slidably connected in the snap-fit ​​groove 21, a pull column 23 slidably connected to the mounting ring 4 fixedly connected to one side of the snap-fit ​​block 22, a connecting block 24 fixedly connected to one end of the pull column 23, a third spring 25 fixedly sleeved on the outer surface of the pull column 23 and fixedly connected to the connecting block 24, the other end of the third spring 25 fixedly connected to the mounting ring 4, and a transmission mechanism connected to the mounting ring 4 provided on the connecting block 24. The transmission mechanism is used to drive the pull column 23 to move away from the center of the mounting ring 4.

[0037] The transmission mechanism includes a rotating ring 31 that is rotatably connected to the mounting ring 4. The rotating ring 31 has multiple arc-shaped grooves 32, and a sliding column 33 that is fixedly connected to the connecting block 24 is slidably connected in the arc-shaped grooves 32.

[0038] The outer surface of the rotating ring 31 is provided with friction texture.

[0039] The connecting plate 3 has a threaded groove 41. The outer surface of the mounting ring 4 is threadedly connected to the threaded groove 41 by the thread 42. After the main body of the pipeline 1 is used up, since the anesthetic gas pipeline is a disposable item, the mounting ring 4 is rotated off the connecting plate 3 by rotating the mounting ring 4. Then the mounting ring 4 is disinfected to achieve the reuse of the anti-detachment fixing mechanism.

[0040] Before installing the connecting bend 2, firstly, by rotating the rotating ring 31, the rotating ring 31 drives the arc groove 32 to rotate, the arc groove 32 drives the sliding column 33 to move, the sliding column 33 drives the connecting block 24 and the pulling column 23 to move, so that the pulling column 23 drives the snap-fit ​​block 22 to move. Then, by pulling the pull ring 14, the pull ring 14 drives the pull plate 13 to move, the pull plate 13 drives the second transmission inclined block 10 to move, the second transmission inclined block 10 drives the first transmission plate 11 to move, the first transmission plate 11 drives the second spring 12 to stretch. At this time, under the action of the first spring 9, the transmission column 6 drives the transmission column 6 and the clamping block 7 to move away from the center of the mounting ring 4. Then, the rotating ring 31 is rotated in the opposite direction, the rotating ring 31 drives the pulling column 23 and the snap-fit ​​block 22 to insert into the snap-fit ​​groove 21, snap-fitting and fixing the pull plate 13. Then, the connecting pipe is connected. In this process, by inserting the connecting bend 2 into the connecting pipe, and then rotating the rotating ring 31, the rotating ring 31 drives the arc groove 32 to rotate, the arc groove 32 drives the sliding column 33 to move, and the sliding column 33 drives the connecting block 24 and the pulling column 23 to move, so that the pulling column 23 drives the snap-fit ​​block 22 to move out of the snap-fit ​​groove 21. Then, under the elastic force of the second spring 12, the second transmission inclined block 10 is driven to move, the second transmission inclined block 10 drives the first transmission inclined block 8 and the transmission column 6 to move, and the transmission column 6 drives the clamping block 7 to move, so that the clamping block 7 clamps and fixes, thereby achieving stable fixation of the connecting bend 2. Through the above operation, when connecting the connecting bend 2, medical staff only need to insert the connecting bend 2 into the connecting pipe and then rotate the rotating ring 31, which facilitates the portable connection of the connecting pipe and realizes the quick connection of the connecting bend 2.

[0041] Working principle:

[0042] Initial setup: Before connecting the bend 2 to the pipe on the oxygen mask, if it is necessary to fix the position of the pull plate 13 in advance so that the connecting pipe can be inserted, first rotate the rotating ring 31 (transmission mechanism component). The rotating ring 31 drives the arc groove 32 (transmission mechanism component) to rotate. The arc groove 32 drives the sliding column 33 (transmission mechanism component) to move. The sliding column 33 drives the connecting block 24 to move. The connecting block 24 drives the pull column 23 (clamping mechanism component) to move. The pull column 23 drives the clamping block 22 (clamping mechanism component) to move.

[0043] Pulling the pull ring 14 and fixing the pull plate 13: Pulling the pull ring 14 causes the pull plate 13 to move, which in turn causes the second transmission inclined block 10 to move. The second transmission inclined block 10 then causes the first transmission plate 11 to move, which in turn causes the second spring 12 to stretch. At this time, under the force of the first spring 9, the transmission column 6 and the clamping block 7 move away from the center of the mounting ring 4. Then, the rotating ring 31 is rotated in the opposite direction. The rotating ring 31 causes the pull column 23 and the snap-fit ​​block 22 to insert into the snap-fit ​​groove 21 (snap-fit ​​mechanism component) on the pull plate 13, thus snapping and fixing the pull plate 13.

[0044] Insert the connecting tube: Insert the connecting bend 2 into the connecting tube on the oxygen mask.

[0045] Release the pull plate 13 and achieve clamping fixation: Rotate the rotating ring 31, which drives the arc groove 32 to rotate. The arc groove 32 drives the sliding column 33 to move, and the sliding column 33 drives the connecting block 24 and the pull column 23 to move, so that the pull column 23 drives the snap-fit ​​block 22 to move out of the snap-fit ​​groove 21. At this time, under the elastic force of the second spring 12, the first transmission plate 11 and the second transmission inclined block 10 are driven to move. The second transmission inclined block 10 drives the first transmission inclined block 8 to move. The first transmission inclined block 8 drives the transmission column 6 to move. The transmission column 6 drives the clamping block 7 to move, so that the clamping block 7 squeezes and clamps the connecting bend 2. The connecting bend 2 deforms under pressure, so that the connecting bend 2 and the connecting tube inserted inside it are tightly fitted together, thereby tightly fitting the connecting bend 2 to the connecting tube on the oxygen mask, realizing the tight connection of the connecting bend 2, preventing the pipeline from falling off, and improving the stability of the anesthetic gas pipeline connection.

[0046] Post-use treatment of the pipeline: After the main body 1 of the pipeline is used up, since the anesthetic gas pipeline is a disposable item, the installation ring 4 is rotated off the connecting plate 3 by rotating the installation ring 4 (the installation ring 4 is threadedly connected to the threaded groove 41 on the connecting plate 3 through the thread 42). Then the installation ring 4 is disinfected to achieve the reuse of the anti-detachment fixing mechanism.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
