Technical Field

[0001] This utility model relates to the field of tracheal plug technology, specifically to a rotatable and adjustable tracheal plug. Background Technology

[0002] Tracheostomy is a common emergency and treatment procedure in clinical practice. It is often used to prevent and treat diseases that may lead to airway obstruction or lower respiratory tract secretion obstruction. When a patient with a tracheostomy is on a ventilator and is ready to be weaned off the ventilator, the tracheostomy tube must be gradually sealed before it can be removed. After a tracheostomy, a metal or disposable silicone tracheostomy tube is routinely placed.

[0003] Existing rotatable and adjustable endotracheal plugs cannot freely adjust ventilation volume and ventilation rate, resulting in insufficient or excessive ventilation volume when used on different patients, thus affecting the effectiveness of use. They have significant limitations. In addition, the lack of further restraint on movable structures makes the device prone to accidental contact that could harm the patient's health, resulting in poor protective effect. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present invention provides a rotatable and adjustable tracheal plug to overcome the above-mentioned technical problems existing in the prior art.

[0005] A rotatable and adjustable tracheal plug includes a plug body, an air guide tube fixedly installed at one end of the plug body, a fixing frame and an annular plate fixedly installed on the inner wall of the air guide tube, a support plate fixedly installed on the inner wall of the fixing frame, a plurality of air vents opened on the top of the support plate, and an adjustment component provided at one end. The adjustment component includes a pull rod, a plurality of sector baffles, a connecting rod and a return spring. The pull rod increases or decreases the blocking area of ​​the plurality of air vents by rotating the plurality of sector baffles. When the pull rod moves, it drives the connecting rod to move and compresses the return spring through the support plate. A plurality of limiting plates are fixedly installed on the inner wall of the annular plate.

[0006] A further improvement of the present invention is that the adjusting assembly further includes a fixing ring and a fixing rod, the two ends of the fixing rod being fixedly connected to the pull rod and the fixing ring respectively, and a plurality of the fan-shaped baffles being fixedly connected to the fixing ring.

[0007] A further improvement of this utility model is that the adjusting assembly further includes a fixing plate, the return spring is rotatably connected to the fixing ring, the fixing plate is fixedly installed at one end of the connecting rod, the return spring is sleeved on the connecting rod, one end of the return spring is connected to the fixing plate, and the other end is connected to the bearing plate, and the connecting rod is slidably engaged with the bearing plate.

[0008] A further improvement of this utility model is that a handle is fixedly installed at one end of the pull rod, and the outer wall of the handle is provided with several anti-slip pads.

[0009] A further improvement of this utility model is that a sealing ring is provided between the plug body and the air guide tube.

[0010] A further improvement of this utility model is that the outer wall of the plug body is provided with several rubber rings.

[0011] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0012] 1. This utility model provides a rotatable and adjustable tracheal plug head. Through the cooperation between the plug body, air guide tube, pull rod, fixing rod, fixing ring, sector baffle, bearing plate and ventilation groove, when the pull rod rotates, it drives the fixing ring and several sector baffles to rotate. After the several sector baffles rotate, the coverage of the ventilation groove is increased, thereby reducing the ventilation volume and ventilation speed. It can be used for patients with different conditions and has strong applicability.

[0013] 2. This utility model provides a rotatable and adjustable air pipe plug head. Through the cooperation of a return spring, a fixed plate, a bearing plate, an annular limiting plate, a sector baffle, and a connecting rod, pulling the pull rod causes the pull rod to move several sector baffles. When the position of several sector baffles exceeds the limiting plate, the pull rod is rotated so that several sector baffles are limited by the limiting plate, thereby reducing the probability of the equipment automatically adjusting the ventilation volume during use and improving the protection effect. At the same time, the return spring can improve the reset speed of the sector baffles and improve the adjustment efficiency. Attached Figure Description

[0021] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0022] like Figure 1-5 As shown, this utility model provides a rotatable and adjustable tracheal plug, including a plug body 2. An air guide tube 3 is fixedly installed at one end of the plug body 2. A fixing frame 6 and an annular plate 8 are fixedly installed on the inner wall of the air guide tube 3. A support plate 7 is fixedly installed on the inner wall of the fixing frame 6. The top of the support plate 7 has several air vents 701, and one end is provided with an adjustment component 4. The adjustment component 4 includes a pull rod 401, several fan-shaped baffles 403, a connecting rod 404, and a return spring 405. The pull rod 401... By rotating several sector-shaped baffles 403, the obstruction area of ​​several ventilation slots 701 can be increased or decreased. When the pull rod 401 moves, it drives the connecting rod 404 to move and compresses the reset spring 405 through the bearing plate 7. Several limiting plates 801 are fixedly installed on the inner wall of the annular plate 8. The adjustment assembly 4 also includes a fixing ring 400 and a fixing rod 402. The two ends of the fixing rod 402 are fixedly connected to the pull rod 401 and the fixing ring 400 respectively. Several sector-shaped baffles 403 are all fixedly connected to the fixing ring 400.

[0023] When the adjustment component 4 is in the default state, all ventilation slots 701 are not blocked, and the ventilation volume and ventilation rate are at their maximum values. When it is necessary to reduce the ventilation volume, the operator rotates the lever 401. After the lever 401 rotates, it drives several fan-shaped baffles 403 to rotate. After rotating a certain range, the fan-shaped baffles 403 begin to block several ventilation slots 701. At this time, the operator can adjust the size of the fan-shaped baffles 403 blocking several ventilation slots 701 according to the rotation range of the adjustment lever 401, thereby achieving the effect of adjusting the ventilation volume and ventilation rate. Different functions can be reasonably adjusted according to the patient's physical condition or illness, increasing the scope of application and making it highly applicable.

[0024] To prevent the lever 401 from easily rotating and affecting normal ventilation during equipment use, the operator first pulls the lever 401, causing it to move several sector baffles 403. This prevents the sector baffles 403 from engaging with the ventilation slots 701, thus removing the adjustment function. Then, after the sector baffles 403 exceed the limit plate 801, the lever 401 is rotated. Once the sector baffles 403 are aligned with the limit plate 801, the lever 401 is released, causing the return springs 405 to release pressure. This keeps the sector baffles 403 abutted by the limit plate 801, reducing the risk of accidental contact with the adjustment component 4 and endangering the patient's life. The adjustment component can be moved to a specific area according to the patient's condition, improving the protective effect and applicability.

[0025] like Figure 4-5 As shown, in one embodiment, the adjusting component 4 further includes a fixing plate 406, a return spring 405 rotatably connected to a fixing ring 400, the fixing plate 406 is fixedly installed on one end of the connecting rod 404, the return spring 405 is sleeved on the connecting rod 404, one end of the return spring 405 is connected to the fixing plate 406, and the other end is connected to the bearing plate 7, and the connecting rod 404 and the bearing plate 7 are slidably engaged.

[0026] The fixed plate 406 can cooperate with the bearing plate 7 to press the return spring 405, thereby improving the reset efficiency and applicability when resetting the adjustment component 4.

[0027] like Figure 3 As shown, in one embodiment, a handle 5 is fixedly installed at one end of the pull rod 401, and a plurality of anti-slip pads 501 are provided on the outer wall of the handle 5.

[0028] The handle 5 and the anti-slip pad 501 can increase the friction between the operator's hand and the lever 401, reduce the probability of hand slippage when adjusting the ventilation volume, and further improve applicability.

[0029] like Figure 2 As shown, in one embodiment, a sealing ring 201 is provided between the plug body 2 and the air guide tube 3, and a plurality of rubber rings 200 are provided on the outer wall of the plug body 2.

[0030] The sealing ring 201 can further improve the fixing effect between the plug body 2 and the air guide tube 3 and extend the service life of the equipment. The plug body 2 and the rubber ring 200 are existing technologies and will not be explained here.

[0031] The working principle of this rotatable and adjustable tracheal plug will be explained in detail below:

[0032] The operator first inserts the plug body 2 into the tracheostomy tube sleeve 1. The rubber ring 200 on its outer wall increases the friction between the tracheostomy tube sleeve 1 and the plug body 2, thus enabling them to be joined together. When the adjustment component 4 is in the default state, the ventilation slots 701 are not blocked, and the ventilation volume and ventilation rate are at their maximum values. When it is necessary to reduce the ventilation volume, the operator rotates the pull rod 401. The rotation of the pull rod 401 drives the fixed rod 402 to rotate. When the fixed rod 402 rotates, it drives the fixed ring 400 and the fan-shaped baffles 403 to rotate. After rotating a certain range, the fan-shaped baffles 403 begin to block the ventilation slots 701. At this time, the operator can adjust the size of the fan-shaped baffles 403 blocking the ventilation slots 701 according to the rotation range of the adjustment pull rod 401, thereby achieving the effect of adjusting the ventilation volume and ventilation rate. Different functions can be reasonably adjusted according to the patient's physical condition or illness, increasing the scope of application and making it highly applicable.

[0033] To prevent the lever 401 from easily rotating and affecting normal ventilation during equipment use, the operator first pulls the lever 401, causing the fixed lever 402 and fixed ring 400 to move. The fixed ring 400 then moves several sector baffles 403, causing them to no longer engage with the ventilation slots 701, thus removing the adjustment function. Then, after the sector baffles 403 exceed the limit plate 801, the lever 401 is rotated, causing the limit plate 801 to limit the sector baffles 403, reducing the risk of accidental contact with the adjustment component 4 and affecting the patient's life safety. The adjustment component can be moved to a certain area according to the patient's condition, improving the protective effect and applicability.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
