[0028] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0029] like Figure 1 and 2 As shown, a tracheotomy tube respiratory volume control device, the device comprising:

[0030] The upper part 1 is a cylindrical structure, which is arranged in the tracheotomy tube and has a buckle rim 3 on the top, and the buckle rim 3 is buckled with the tracheotomy tube; Figure 1 As shown, during installation, after the upper component 1 is placed into the tracheotomy tube, the buckle flange 3 is placed at the tube mouth of the tracheotomy tube. The buckle flange 3 is used to place the upper component 1 into the tracheotomy tube; the outer diameter of the upper component 1 is slightly smaller than the inner diameter of the tube mouth of the tracheotomy tube, so that the upper component 1 can rotate freely in the tracheotomy tube.

[0031] The lower part 2 is a cylindrical structure, fixed in the tracheotomy tube, and movably connected to the upper part 1; Figure 1 As shown, the outer diameter of lower component 2 is larger than that of upper component 1, and its outer surface is coated with a non-slip layer. The outer diameter of lower component 2 is approximately equal to the inner diameter of the tracheostomy tube's orifice. During installation, the tracheostomy tube can be soaked in hot water for five minutes before the lower component is installed at the orifice of the tracheostomy tube. Because the outer surface of lower component 2 is coated with a non-slip layer, when upper component 1 rotates on lower component 2, lower component 2 remains relatively stationary and does not slip. The inner side of lower component 2 is equipped with a structure that cooperates with respiratory volume adjustment component 4 to achieve precise control of airflow.

[0032] The breathing volume regulating component 4 is arranged inside the lower component 2 through the support rod 5, and one end is arranged on the top of the inner side of the lower component 2, and the other end is arranged on the inner side of the upper component 1 through the clamp 6. Figure 2 and 5 As shown, one end of the support rod 5 is fixed to the inner side of the lower part 2, and the other end is fixed to the central column 401 of the respiratory volume adjustment part 4, thereby supporting the respiratory volume adjustment part 4. The respiratory volume adjustment part 4 includes a central column 401 connected to the support rod 5; a plurality of support strands 402, all movably arranged on the central column 401; a sealing membrane 403, attached to the support strands 402, and the support strands 402 are used to open the sealing membrane 403; a moving block 404, installed at the end of the support strands 402 and used in conjunction with the clamp 6. The support strands 402 are arranged to overlap with each other to ensure that the sealing membrane 403 can be evenly expanded when adjusting the respiratory volume, thereby achieving uniform control of the airflow. The maximum area of ​​the sealing membrane 403 after being opened is less than three-quarters of the cross-sectional area of ​​the inner cavity of the lower part 2, to ensure that it does not cause excessive resistance to the ventilation of the tracheotomy tube during the adjustment process. The overall shape of the respiratory volume regulating component 4 is similar to a folding fan. The surface area of ​​the respiratory volume regulating component 4 in the lower component 2 can be controlled by controlling the supporting strands 402 on both sides. The larger the surface area of ​​the respiratory volume regulating component 4, the smaller the patient's respiratory volume. Therefore, the patient's respiratory volume can be accurately controlled by controlling the surface area of ​​the respiratory volume regulating component 4. Figure 5 As shown, a moving block 404 is fixedly installed at the end of the rightmost support strand 402. During installation, the moving block 404 is clamped on a clamp 6 fixed on the inner wall of the upper component. Therefore, the surface area of ​​the respiratory volume regulating component 4 can be controlled by controlling the position of the clamp 6. Since the clamp 6 is fixed on the upper component 1, the surface area of ​​the respiratory volume regulating component 4 can be directly controlled by rotating the upper component 1.

[0033] like Figures 1 to 5As shown, before use, the upper component 1 is first snapped onto the lower component 2, and the rightmost movable block 404 of the respiratory volume adjustment component 4 is snapped onto the clamping member 6, while the leftmost movable block 404 of the respiratory volume adjustment component 4 is fixed to the inner wall of the lower component 2. The assembled respiratory volume control device is then installed at the tube mouth of the tracheostomy tube. The lower component 2 is now fixed to the inner wall of the tracheostomy tube. During use, the surface area of ​​the respiratory volume adjustment component 4 is adjusted by rotating the upper component 1, thereby achieving precise control of the patient's respiratory volume. The device is simple to use and easy to operate. It can be adjusted in real time according to the patient's actual condition, ensuring that the patient receives the appropriate ventilation volume in different situations. During specific implementation, medical staff can flexibly adjust the respiratory volume according to the patient's actual needs to adapt to changes in the patient's respiratory rate and depth. In actual application, medical staff can adjust the respiratory volume by rotating the upper component 1 according to the patient's condition. For example, if the patient needs to increase the ventilation volume, the surface area of ​​the respiratory volume adjustment component 4 can be appropriately reduced, and vice versa. This real-time adjustment function enables medical staff to respond to various emergencies more flexibly and provide patients with more personalized respiratory support.

[0034] As an optional embodiment of the present invention, optionally, the respiratory volume adjustment component 4 includes:

[0035] Central column 401, connected to the support rod 5;

[0036] A plurality of support strands 402 are movably mounted on the central column 401;

[0037] The sealing film 403 is provided on the supporting strands 402, and the supporting strands 402 are used to open the sealing film 403;

[0038] The moving block 404 is disposed at the end of the supporting strand 402 and cooperates with the clamping member 6 .

[0039] like Figure 5As shown, all the support strands 402 are mounted on a central column 401. The central column 401 is made of metal and has a relatively strong hardness. All the support strands 402 can rotate with the central column 401 as the axis. When in use, the end of the leftmost support strand 402 is fixed to the lower component 2, and the end of the rightmost support strand 402 is connected to the clamp 6 installed on the inner wall of the upper component 1 through a movable block 404. By rotating the upper component 1, the rightmost support strand 402 can be driven to rotate, thereby changing the surface area of ​​the respiratory volume regulating component 4, thereby achieving precise control of the patient's respiratory volume. In actual application, medical staff can adjust the respiratory volume by rotating the upper component 1 according to the changes in the patient's condition. For example, when the patient needs to increase the ventilation volume, the surface area of ​​the respiratory volume regulating component 4 can be appropriately reduced, and vice versa. This real-time adjustment function allows medical staff to respond to various emergencies more flexibly and provide patients with more personalized respiratory support.

[0040] As an optional embodiment of the present invention, optionally, the support strands 402 are arranged to overlap with each other.

[0041] The overlapping arrangement of the support strands 402 prevents them from interfering with each other during retraction or deployment, potentially preventing the sealing membrane 403 from evenly deploying. This overlapping design ensures that each support strand 402 can move independently during respiratory volume adjustment, preventing mutual interference and thus ensuring the stability and reliability of the respiratory volume adjustment component 4. Furthermore, the overlapping arrangement makes the respiratory volume adjustment component 4 more compact when retracted, reducing its footprint and facilitating installation and removal of the device.

[0042] As an optional embodiment of the present invention, optionally, the maximum area of ​​the sealing membrane 403 after being expanded is less than three quarters of the cross-sectional area of ​​the inner cavity of the lower component 2 .

[0043] like Figure 2 As shown, when the sealing membrane 403 of the respiratory volume adjustment component 4 is fully expanded, to prevent improper operation from causing excessive resistance to the tracheostomy tube, the maximum area of ​​the sealing membrane 403 is designed to be less than three-quarters of the cross-sectional area of ​​the inner cavity of the lower component 2. This design ensures that even in the maximum expanded state, the respiratory volume adjustment component 4 does not cause unnecessary obstruction to airflow, thereby ensuring smooth ventilation for patients using the device. Furthermore, by controlling the degree of expansion of the sealing membrane 403, fine-tuning of the airflow can be achieved to meet the ventilation requirements of different patients.

[0044] As an optional embodiment of the present invention, optionally, a protrusion 7 is provided on the lower component 2, and a recess cooperating with the protrusion 7 is provided on the inner wall of the upper component 1, and the protrusion 7 cooperates with the recess to clamp the upper component 1 to the lower component 2.

[0045] like Figure 3 As shown, the protrusions 7 are integrally formed with the lower component 2, and the outer periphery of the lower component 2 is provided with protrusions 7. The upper component 1 and the lower component 2 are fixed together by the protrusions 7 fitting into the recesses on the inner wall of the upper component 1. This snap-fitting method ensures the stability and reliability of the device without affecting the free rotation of the upper component 1 on the lower component 2.

[0046] As an optional embodiment of the present invention, optionally, a scale line is provided on the top of the lower component 2.

[0047] The provision of graduated lines (not shown) on the top of the lower component allows medical personnel to more intuitively understand changes in the surface area of ​​the respiratory volume adjustment component 4. The graduated lines facilitate precise measurement and recording of each adjustment, thereby providing more accurate respiratory support for the patient. In practice, medical personnel can quickly adjust the surface area of ​​the respiratory volume adjustment component 4 based on the patient's respiratory condition and the indications of the graduated lines, ensuring the patient receives the appropriate ventilation volume. Furthermore, the graduated lines facilitate tracking and comparison of the patient's respiratory status at different time points, enabling timely adjustments to treatment plans.

[0048] As an optional embodiment of the present invention, optionally, the horizontal line of one side of the respiratory volume regulating component 4 is lower than the horizontal line of the other side.

[0049] like Figure 5 As shown, it should be noted that one side here refers to the horizontal line where the leftmost support strand 402 is installed, and the other side refers to the rightmost support strand 402. The leftmost support strand 402 is fixed to the lower component 2, and the rightmost support strand 402 is fixed to the upper component 1. Designing the two support strands 402 with one higher and one lower helps prevent the support strands 402 from interfering with each other when closing, thereby ensuring that the sealing membrane 403 can be evenly expanded. This design makes the respiratory volume adjustment component 4 more stable during the adjustment process and avoids deformation or damage to the sealing membrane 403 caused by interference between the support strands 402.

[0050] As an optional embodiment of the present invention, optionally, the outer diameter of the upper component 1 is smaller than the inner diameter of the tracheotomy tube, and the outer diameter of the buckle flange 3 on the upper component 1 is larger than the outer diameter of the tracheotomy tube.

[0051] like Figure 1As shown, the outer diameter of the upper component 1 is designed to be smaller than the inner diameter of the tracheostomy tube to ensure smooth insertion of the upper component into the tube and avoid unnecessary damage to the patient during insertion. Furthermore, the outer diameter of the flange 3 on the upper component 1 is larger than the outer diameter of the tracheostomy tube. This design prevents the device from sliding into the tracheostomy tube after installation.

[0052] As an optional embodiment of the present invention, optionally, the outer diameter of the upper component 1 is smaller than the outer diameter of the lower component 2 .

[0053] like Figure 1 As shown, the outer diameter of the upper component 1 is slightly smaller than that of the lower component 2. This allows the upper component 1 to rotate relative to the lower component 2 and the tracheostomy tube even when the lower component 2 is secured to the inner wall of the tracheostomy tube. This design prevents relative movement between the upper and lower components 1, 2, allowing the respiratory volume adjustment component 4 to flexibly adjust its surface area, thereby achieving precise control of the patient's respiratory volume. Furthermore, the smaller outer diameter of the upper component 1 than that of the lower component 2 facilitates rotation and adjustment of the device by medical personnel during operation, improving ease of use.

[0054] As an optional embodiment of the present invention, optionally, the buckle eaves 3 are integrally formed with the upper component 1. Integrating the buckle eaves 3 with the upper component 1 can improve the structural stability of the upper component 1.

[0055] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
