Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to an anti-detachment breathing circuit tube. Background Technology
[0002] Ventilators are used for emergency ventilation and resuscitation of patients with respiratory failure, or for mechanical ventilation during operation. Therefore, the stability of the connection between the tracheostomy cannula and the return tubing is crucial during the use of oxygen ventilators. However, in practical applications, the connector between the tracheostomy cannula and the return tubing is usually a plug-in type, making the connection prone to detachment under external tension. This problem seriously affects the patient's treatment outcome and safety. When the return tubing and tracheostomy cannula are not securely connected, it may lead to an interruption of oxygen supply, resulting in decreased oxygen saturation and symptoms such as difficulty breathing, which can even be life-threatening in severe cases. Furthermore, detachment can increase the workload of medical staff, requiring frequent checks and re-secured connections, reducing medical efficiency. Therefore, effectively solving the problem of easy detachment of the tracheostomy cannula and return tubing connection has become a pressing challenge in the medical device field, prompting the design and development of anti-detachment breathing return tubing.
[0003] Therefore, a breathing circuit tube to prevent detachment was proposed. Utility Model Content

[0021] Example 1: Please refer to Figure 1-4This utility model provides a technical solution: an anti-detachment breathing circuit tube, comprising a tube body 1 composed of an outer sleeve 2 and an inner sleeve 3 connected to each other. It should be noted that the tube body 1 refers to a tracheostomy tube, which is prior art. It also includes a circuit tube 4 disposed on one side of the interface end of the inner sleeve 3 for delivering oxygen. The two ends of the circuit tube 4 are respectively connected to a first connector and a second connector. It should be noted that the first connector and the second connector can be used to connect the circuit tubes 4 to each other, or to connect the circuit tube 4 to the inner sleeve 3. The first connector includes a connection that communicates with the interior of the circuit tube 4. The other end of the connecting pipe 5 is inserted into the interface end of the inner sleeve 3. A right connector 7 is installed on the outer wall of the connecting pipe 5. A return spring 8 is installed inside the right connector 7 and is sleeved on the outside of the connecting pipe 5. A first sealing block 9 is installed on the other end of the return spring 8. The other side of the first sealing block 9 is pressed against the interface end of the inner sleeve 3 to ensure the sealing of the pipe at the connection. A limiting part is connected to the outer wall of the right connector 7. The limiting part controls the inner sleeve 3 to compress the return spring 8 and fix it inside the right connector 7 to prevent it from falling off and improve the stability of the connection between the circuit pipe 4 and the inner sleeve 3.
[0022] In this embodiment, the limiting part includes two grooves 10 disposed opposite to each other inside the right connector 7. A slider 11 is slidably installed inside each of the two grooves 10. A limiting block 14 for limiting the sliding of the inner sleeve 3 inside the right connector 7 is installed on one side of each of the two sliders 11. The opposite ends of the two limiting blocks 14 are inclined. A limiting spring 12 is installed on the other side of each of the two sliders 11. An inspection cover 13 is installed on the other end of each of the two limiting springs 12 and is detachably installed on the right connector 7. A pull plate is provided inside each of the two limiting springs 12. One end of each pull plate is fixed to the corresponding slider 11.
[0023] The other ends of the two pull plates pass through the corresponding inspection covers 13 and extend to the outside. The opposite sides of the two limiting blocks 14 are connected to the limiting ring 15 and fixedly installed on the inner sleeve 3. The limiting ring 15 is pressed against the contact surface of the first sealing block 9. The outer wall of the limiting ring 15 is provided with a limiting groove 16 for fixing the moving position of the corresponding limiting block 14.
[0024] In this embodiment, a third sealing block 19 is installed on the inner side wall of the interface end of the inner sleeve 3, and a matching second sealing block 18 is provided on one side of the third sealing block 19.

The Velcro strap 22 can be fixedly attached to the fabric strip of the sleeve body 1 to further fix it and prevent it from falling off. The hanger 21 can fix the pipe in a certain position to prevent the pipe from shaking randomly.
[0028] The working principle is as follows: In actual use, the connecting pipe 5 is first inserted into the interface end of the inner sleeve 3. At this time, the first sealing block 9 is pressed against the interface end of the inner sleeve 3 to ensure sealing. The limiting ring 15 on the inner sleeve 3 is inserted between the two limiting blocks 14. Under the action of the limiting spring 12, the limiting block 14 is embedded in the limiting groove 16 of the limiting ring 15 to fix the position of the inner sleeve 3 and prevent it from falling off. If there are multiple circuit pipes connected, the left connector 6 interface end of one circuit pipe is connected to the right connector 7 of another circuit pipe. The fourth sealing block 24 and the retaining ring 23 cooperate to ensure tight connection and good sealing.
[0029] At the same time, use the hanger 21 to suspend the loop pipe 4 in a suitable position, and then use Velcro strap 22 to stick it to the fabric strip of the sleeve body 1 to further fix the pipeline and prevent shaking and falling off. After the connection is completed, check whether the entire pipeline connection is firm and whether the seal is good. During use, check the pipeline connection parts regularly to ensure that there is no loosening or falling off, and ensure stable oxygen delivery.
