Description

Technical Field

[0001] This application relates to the technical field of respiratory tubing protection, and in particular to a respiratory tubing anti-contamination stent. Background Technology

[0002] After a certain period of assisted breathing with a ventilator, critically ill patients will undergo weaning training, which is to train their spontaneous breathing ability. If their spontaneous breathing ability is poor, they will continue to use a ventilator for assisted breathing.

[0003] During off-ventilator training, the breathing tubing connected to the artificial airway is directly exposed to the air.

[0004] There are usually several patients in a ward, and the ends of the breathing tubes exposed to the air pose a significant risk of cross-infection. Connecting a breathing tube with a high risk of cross-infection to an artificial airway will worsen the patient's condition. Utility Model Content

[0005] To reduce cross-infection in breathing tubing, this application provides a breathing tubing anti-contamination stent.

[0006] This application provides a respiratory tubing anti-contamination stent, which adopts the following technical solution: A respiratory tubing anti-contamination support includes a protective mechanism comprising a support frame and a protective cap. The support frame is used to mount the tubing on a hospital bed or ventilator, and the protective cap is mounted on the support frame, with the end of the respiratory tubing located inside the protective cap.

[0007] By adopting the above technical solution, the support frame is installed on the hospital bed or ventilator. When the patient is weaned off the ventilator, the end of the breathing tube connected to the artificial airway is locked with the protective cap. Therefore, the protective mechanism can reduce the cross-infection caused by the end of the breathing tube being exposed to the air for a long time. When the breathing tube is subsequently connected to the artificial airway, the phenomenon of the patient's condition worsening due to the large amount of contamination in the breathing tube will be reduced.

[0008] Optionally, the support frame includes a support block, a positioning bolt, and a support rod. The support block has a support groove and a first threaded hole communicating with the support groove. The positioning bolt is threadedly connected to the first threaded hole. The support rod is disposed on the support block, and the protective cap is disposed on the support rod.

[0009] By adopting the above technical solution, the support groove on the support block is snapped into the hospital bed or ventilator; then the positioning bolt is rotated to make the positioning bolt press against the hospital bed or ventilator, thereby fixing the support block to the hospital bed or ventilator; then the end of the breathing tube is snapped into the protective cap on the support rod to reduce the occurrence of cross-infection at the end of the breathing tube.

[0010] Optionally, the support rod includes a fixed rod, a sliding rod, and a fixing bolt. The fixed rod is disposed on the support block and has a groove and a second threaded hole communicating with the groove. The sliding rod is slidably disposed in the groove. The fixing bolt is threadedly connected to the second threaded hole and abuts against the sliding rod located in the groove. The protective cap is disposed on the sliding rod.

[0011] By adopting the above technical solution, the sliding rod slides within the groove of the fixed rod. Once the position of the sliding rod is determined, the fixing bolt is rotated to press against the sliding rod located in the groove, thus fixing the sliding rod onto the fixed rod. The position of the sliding rod will change the position of the protective cap after the position of the sliding rod changes. Therefore, setting an adjustable-length support rod can improve applicability.

[0012] Optionally, the support rod is provided with a limiting component, the limiting component including a stabilizing rod and a buckle, the stabilizing rod being...

[0013] By adopting the above technical solution, after the end of the breathing tube is inside the protective cap, a part of the breathing tube is placed in the buckle, reducing the phenomenon of the breathing tube separating from the breathing cap due to gravity; therefore, the setting of the limiting component can limit the breathing tube, thereby enabling the protective cap to better protect the breathing tube.

[0014] Optionally, the support frame is provided with an elastic strap, and the protective cap is disposed on the elastic strap.

[0015] By adopting the above technical solution, the elastic strap can deform, thereby changing the position of the protective cap and allowing the end of the breathing tube to better enter the protective cap, thus improving its applicability.

[0016] Optionally, it also includes a stabilizing mechanism, which includes a first connecting block, a second connecting block, an adjusting block, an adjusting component, and a limiting component. The first connecting block is connected to the elastic strap, and a limiting groove is provided on the first connecting block. The second connecting block is disposed on the first connecting block, and the adjusting block is disposed on the second connecting block through the adjusting component. The protective cap is connected to the adjusting block.

[0017] By adopting the above technical solution, the breathing tubing is confined within the limiting groove of the first connecting block by the limiting component; then, by adjusting the component to change the position of the adjusting block, the position of the protective cap is changed, thereby allowing the end of the tubing located in the limiting groove to enter the protective cap; the stabilizing mechanism can improve the stability of the breathing tubing within the protective cap.

[0018] Optionally, the limiting component includes a rotating shaft, a limiting block, and a torsion spring. The rotating shaft is rotatably mounted on the first connecting block, the limiting block is mounted on the rotating shaft, and the limiting block can block the limiting groove. The torsion spring is sleeved on the rotating shaft, with one end of the torsion spring connected to the rotating shaft and the other end connected to the first connecting block.

[0019] By adopting the above technical solution, rotating the limiting block will cause the torsion spring to deform, so that the limiting block will no longer block the limiting groove; then the medical staff will place the breathing tube into the limiting groove and release the limiting block. The force of the torsion spring restoring its elastic deformation will drive the limiting block to move, so that the limiting block will abut against the breathing tube located in the limiting groove, thereby limiting the breathing tube to the first connecting block.

[0020] Optionally, the adjustment assembly includes an adapter block and an adjustment screw. The adapter block is disposed on the second connecting block and has a third threaded hole. One end of the adjustment screw is connected to the adjustment block and the other end is threadedly connected to the third threaded hole.

[0021] By adopting the above technical solution, rotating the protective cap will cause the adjusting block on the protective cap to rotate the adjusting screw, which in turn will cause the adjusting block and the protective cap to change their positions relative to the adapter block, thereby changing the position of the protective cap relative to the second connecting block. This allows the end of the breathing tube to better enter the protective cap. Moreover, the adjusting assembly makes it easier to replace the protective cap and reduces the need for prolonged use of the protective cap.

[0022] Optionally, the second connecting block is provided with an adjustment mechanism, the adjustment mechanism including a third connecting block and a fixing component, the third connecting block being slidably disposed on the second connecting block, and the adjustment block being connected to the third connecting block through the adjustment component; the fixing component being disposed on the second connecting block and connected to the third connecting block.

[0023] By adopting the above technical solution, the third connecting block slides on the second connecting block, the third connecting block changes the position of the adjusting block through the adjusting component, and then the fixing component fixes the third connecting block on the second connecting block; the setting adjustment mechanism can improve applicability.

[0024] Optionally, the fixing component includes a fixing block, a toggle block, and a second spring. The fixing block is slidably disposed on the second connecting block, and the third connecting block has a fixing groove that engages with the fixing block. The toggle block is disposed on the fixing block, and one end of the second spring is connected to the fixing block and the other end is connected to the second connecting block.

[0025] By adopting the above technical solution, the actuating block drives the fixed block to move away from the third connecting block, so that the fixed block separates from one of the fixing slots, and the second spring will deform; the force of the first spring restoring its elastic deformation drives the third connecting block to move. When the first spring fully restores its elastic deformation, the actuating block is released, and the force of the second spring restoring its elastic deformation drives the fixed block to move closer to the third connecting block, so that the fixed block is engaged with the fixing slot on the third connecting block again.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The protective mechanism can reduce the cross-infection caused by prolonged exposure of the end of the breathing tube to the air. When the breathing tube is subsequently connected to the artificial airway, it will reduce the possibility of the patient's condition worsening due to the contamination of the breathing tube. 2. The elastic straps can deform to change the position of the protective cap, allowing the end of the breathing tube to better enter the protective cap and thus improving its applicability; 3. The adjustable mechanism improves applicability. Attached Figure Description

A toggle block 532 is integrally provided on the end of the fixing block 531 away from the third connecting block 51. The second connecting block 42 is provided with a second spring 533. One end of the second spring 533 is connected to the slider 534 and the other end is connected to the second connecting block 42. .

[0043] refer to Figure 4 and Figure 5 An adjustment component 44 is provided at one end of the third connecting block 51 near the first connecting block 41. The adjustment component 44 includes a transition block 441 fixedly connected to the third connecting block 51. A third threaded hole is provided on the transition block 441.

[0044] A protective groove 21 is formed on the protective cap 2, and a filter cotton pad is placed in the protective groove 21.

[0045] The implementation principle of the anti-pollution stent for a breathing tubing in this embodiment is as follows: The support block 11 is connected to the hospital bed or ventilator; then, the sliding rod 132 in the support rod 13 slides on the fixed rod 131 in the support rod 13. After the position of the sliding rod 132 is determined, the fixing bolt 133 is rotated to tighten against the sliding rod 132. Initially, the first spring 52 deforms, the fixing block 531 engages with one of the fixing grooves 511 on the third connecting block 51, and the second spring 533 is in its normal state.

[0046] When the breathing tube is separated from the artificial airway, first rotate the limiting block 452, and the torsion spring 453 will deform; then the breathing tube is put into the limiting groove 411 of the first connecting block 41, and then the limiting block 452 is released. The force of the torsion spring 453 restoring its elastic deformation drives the limiting block 452 to move, and the limiting block 452 will confine the breathing tube within the limiting groove 411.

[0047] Then, the medical staff pushes the actuating block 532, which moves the fixing block 531, separating it from one of the fixing slots 511 on the third connecting block 51. The force of the first spring 52 restoring its elastic deformation moves the third connecting block 51, which in turn moves the adapter block 441 closer to the first connecting block 41. The adjusting screw 442 on the adapter block 441 moves the adjusting block 43, which in turn moves the protective cap 2, allowing the breathing tube to enter the protective slot 21 of the protective cap 2. At this time, the second spring 533 is compressed. Next, the operator releases the actuating block 532, and the force of the second spring 533 restoring its elastic deformation causes the slider 534 to move the fixing block 531 closer to the third connecting block 51, whereby the fixing block 531 engages with the fixing slot 511 on the third connecting block 51. Then, a portion of the breathing tube is placed into the latch 142.

[0048] If, when the first spring 52 recovers its elastic deformation, there is still a certain distance between the protective cap 2 and the breathing tube, rotating the protective cap 2 will cause the adjusting block 43 to rotate, and the adjusting screw 442 on the adjusting block 43 will move relative to the adapter block 441, so that the end of the breathing tube enters the protective cap 2.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
