Description

Technical Field

[0001] This invention belongs to the technical field of respiratory exercise assistive devices for lung cancer, and particularly relates to a respiratory exercise device for lung cancer patients and a method for marking scale lines thereon. Background Technology

[0002] Lung cancer is one of the fastest-growing malignant tumors in terms of incidence and mortality, posing the greatest threat to public health and life. In men, lung cancer ranks first in both incidence and mortality among all malignant tumors, while in women it ranks second in both. Early-stage lung cancer can be treated surgically, but lung cancer surgery is very complex. Patients need to undergo preoperative examinations to assess their ability to tolerate surgery, including pulmonary function tests, electrocardiograms, and chest X-rays. If preoperative pulmonary function is not up to standard, rehabilitation exercises are required before surgery. Importantly, patients who have had a large amount of lung tissue removed also need postoperative pulmonary function rehabilitation exercises to adapt to and enhance their lung function after the resection. During respiratory exercises, respiratory support devices are required. Traditional lung cancer respiratory support devices are space-consuming and have a fixed intensity, making them inconvenient for patients at different stages of the disease to perform respiratory training.

[0003] To address the aforementioned issues, Chinese invention patent application number 2021110641708.5 discloses a respiratory assist device for lung cancer rehabilitation. This device uses a combination of screws and sleeves to alter the friction between the sealing cylinder and the rubber sleeve, thus adapting to patients at different stages. However, this method of adjusting the friction between the rubber sleeve and the sealing cylinder using screw rotation requires extremely high precision control. Furthermore, the rubber sleeve has a certain degree of flexibility; even if the screw rotates by the same degree, the friction between the rubber sleeve and the sealing cylinder may not be equal. Inaccurate friction control makes it difficult to control the magnitude of friction, and slight oversights can lead to excessive friction, causing the device to malfunction. Additionally, the numerous internal components require high manufacturing precision, increasing the device's manufacturing cost and resulting in low economic efficiency. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a breathing exercise device for lung cancer patients and a method for marking the scale lines thereon, so as to solve the problem that the friction control between the rubber sleeve and the sealing cylinder inside the existing breathing exercise device is not accurate, which easily leads to the device not working properly.

[0005] The present invention solves the above-mentioned technical problems through the following technical means:

[0006] A breathing exercise device for lung cancer patients includes a force adjustment mechanism and a breathing leak prevention mechanism. The force adjustment mechanism is installed at the bottom of the breathing leak prevention mechanism. The force adjustment mechanism includes a sealing cylinder with openings at both ends. One end of the sealing cylinder is seamlessly connected to the breathing leak prevention mechanism, and the other end of the sealing cylinder is hinged to a mounting ring. The mounting ring is provided with a breathing plate and a flow-blocking plate for blocking the breathing plate. The breathing plate is detachably connected to the mounting ring and has a plurality of breathing holes for breathing. The flow-blocking plate is slidably connected to the mounting ring and is located on the side of the breathing plate away from the sealing cylinder. By sliding the flow-blocking plate, the number of breathing holes can be changed. The side of the flow-blocking plate away from the sealing cylinder has a scale line, and the scale line corresponds to the suction strength corresponding to the number of breathing holes.

[0007] Based on the above technical solution, the present invention has also made the following improvements:

[0008] Furthermore, the sealing cylinder includes an upper cylinder and a lower cylinder, which are detachably connected. The other end of the upper cylinder is connected to the breathing leak-proof mechanism, and the other end of the lower cylinder is connected to the mounting ring. The detachable design facilitates cleaning of the interior of the sealing cylinder.

[0009] Furthermore, the mounting ring includes a ring body and a retaining ring threadedly connected to the inner sidewall of the ring body. The inner sidewall of the ring body is provided with a step for abutting the breathing pad. The ring body has a slot for sliding connection with the flow-blocking plate. The ring body is provided with a fastening screw for fixing the flow-blocking plate.

[0010] Furthermore, the inner wall of the buckle is provided with anti-slip strips to prevent slippage during installation or removal.

[0011] Furthermore, the breathing leak-proof mechanism is symmetrically equipped with ropes, with at least two ropes on each side. This allows it to be directly secured to the head of the lung cancer patient, eliminating the need for prolonged holding.

[0012] Furthermore, a method for marking the scale lines of a breathing exercise device for lung cancer patients involves installing a piston in the sealed cylinder, with one end of the piston connected to a force counter. The flow-blocking plate is slid to ensure the breathing orifice is in a fully open state. The minimum force A required to slide the piston is recorded. By sliding the flow-blocking plate, the number of breathing orifices in the open state is changed, and the minimum force B required to slide the piston is recorded again. The minimum force B minus the minimum force A yields the minimum suction force C required for inhalation corresponding to the number of breathing orifices in the open state. This minimum suction force C is marked at the corresponding position on the flow-blocking plate. By changing the number of breathing orifices in the open state, this calculation is repeated multiple times to mark the minimum suction force required for different numbers of breathing orifices in the open state until the scale lines are marked. This scale line visually indicates the suction force used during breathing exercises, and the minimum required suction force can be adjusted by sliding the flow-blocking plate, making adjustment more convenient.

[0013] The beneficial effects of this invention are as follows: the suction force required for breathing exercises can be adjusted by changing the number of breathing holes. The entire device can be made of lightweight materials such as plastic, with a simple structure and low manufacturing cost. Breathing can be carried out as long as the breathing holes of the breathing plate are not completely blocked. Adjustment is more convenient and there will be no situation where it cannot be used.

Detailed Implementation

[0024] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0025] like Figures 1 to 8 As shown

[0026] A breathing exercise device for lung cancer patients includes a force adjustment mechanism 1 and a breathing leak prevention mechanism 2. The force adjustment mechanism 1 is installed at the bottom of the breathing leak prevention mechanism 2. The force adjustment mechanism 1 is used to adjust the minimum suction force of the patient's inhalation during exercise. The breathing leak prevention mechanism 2 is used to prevent air leakage during breathing exercise.

[0027] The force adjustment mechanism 1 includes a sealing cylinder 11 with openings at both ends. One end of the sealing cylinder 11 is seamlessly connected to the breathing leak-proof mechanism 2, and the other end of the sealing cylinder 11 is hinged to a mounting ring 12. The mounting ring 12 is provided with a breathing pad 13 and a flow-blocking plate 14 for blocking the breathing pad 13. The breathing pad 13 is detachably connected to the mounting ring 12 for easy replacement of a new breathing pad 13. The breathing pad 13 is provided with several breathing holes 15 for breathing. The flow-blocking plate 14 is slidably connected to the mounting ring 12 and is located on the breathing pad 13. On the side away from the sealing cylinder 11, the number of airflow holes 15 can be changed by sliding the flow-blocking plate 14. The more airflow holes, the easier it is to inhale and the lower the minimum suction required. The fewer airflow holes, the more difficult it is to inhale and the higher the minimum suction required. By changing the number of airflow holes 15, the suction required for breathing exercises can be adjusted. The entire device can be made of lightweight materials such as plastic, with a simple structure and low manufacturing cost. As long as the airflow holes 15 of the breathing plate 13 are not completely blocked, breathing can be performed. Adjustment is more convenient and there will be no situation where it cannot be used.

[0028] During breathing exercises, the lung cancer patient's mouth and nose are sealed with the breathing leak-proof mechanism 2. The breathing plate 13, flow-blocking plate 14, and mounting ring 12, under the influence of gravity, cover the other end of the sealing cylinder 11. During exhalation, due to the small diameter of the breathing hole 15, gas flow is slow. The increased air pressure inside the sealing cylinder 11 pushes the mounting ring 12 upwards, opening the sealing cylinder 11 and allowing gas to flow out smoothly. After exhalation, the breathing plate 13, flow-blocking plate 14, and mounting ring 12, under the influence of gravity, close the sealing cylinder 11 again. During inhalation, under the resistance of the sealing cylinder 11, gas can only flow into the sealing cylinder 11 through the breathing hole 15. By sliding the flow-blocking plate 14, the number of breathing holes 15 can be changed, thereby adjusting the required suction force during inhalation.

[0029] Specifically, the flow-blocking plate 14 is provided with a scale line 16 on the side away from the sealing cylinder 11. The scale line 16 corresponds to the suction force corresponding to the number of air holes 15. The scale line 16 is set to facilitate the adjustment of the suction force required during breathing exercises.

[0030] Specifically, the sealing cylinder 11 includes an upper cylinder 111 and a lower cylinder 112. The upper cylinder 111 and the lower cylinder 112 are detachably connected. The other end of the upper cylinder 111 is connected to the breathing leak prevention mechanism 2, and the other end of the lower cylinder 112 is connected to the mounting ring 12, which facilitates better cleaning of the inside of the sealing cylinder 11.

[0031] Specifically, the mounting ring 12 includes a ring body 121 and a retaining ring 122 threadedly connected to the inner wall of the ring body 121. The outer wall of the retaining ring 122 has an external thread, and the inner wall of the ring body has an internal thread. The inner wall of the ring body 121 has a step 123 for abutting the breathing pad 13. In use, the breathing pad 13 is first abutted against the step 123, and then the retaining ring 122 is installed. The retaining ring 122 can fix the breathing pad 13 in the ring body 121. The ring body 121 has a slot 124 for sliding connection with the flow-blocking plate 14. The thickness of the slot 124 is equal to the thickness of the flow-blocking plate 14. The ring body 121 has a fastening screw for fixing the flow-blocking plate 14 to prevent the flow-blocking plate 14 from sliding out of the slot 124.

[0032] Specifically, the inner wall of the buckle 122 is provided with an anti-slip strip 125, which facilitates the disassembly or installation of the buckle 122 and prevents slippage during disassembly or installation.

[0033] Specifically, the respiratory leak prevention mechanism 2 is symmetrically provided with ropes 3, with at least two ropes 3 on each side. The ropes 3 can be used to fix the device to the patient's head, avoiding long-term manual holding and making it more convenient to use.

[0034] A method for marking the scale lines of a breathing exercise device for lung cancer patients, wherein the scale line 16 is prepared as follows: A piston is installed in the sealed cylinder 11, and one end of the piston is connected to a force counter 4. The flow-blocking plate 14 is slid to make the breathing hole 15 fully open. The minimum force A required to pull the piston is recorded. The number of breathing holes 15 is changed by sliding the flow-blocking plate 14. Then the minimum force B required to pull the piston is recorded. The minimum force B minus the minimum force A is obtained to obtain the minimum suction force C required for inhalation in the state corresponding to the number of breathing holes 15. The minimum suction force C is marked on the corresponding position of the flow-blocking plate 14. By changing the number of breathing holes 15, the calculation is repeated multiple times to mark the minimum suction force required for different numbers of breathing holes 15 until the scale line 16 is marked.

[0035] The method of using this invention is as follows: The mouth and nose of the lung cancer patient are sealed with the breathing leak-proof mechanism 2. The breathing plate 13, the flow-blocking plate 14, and the mounting ring 12 cover the other end of the sealing cylinder 11 under the action of gravity. When exhaling, the air pressure inside the sealing cylinder 11 increases, pushing the mounting ring 12 to rotate upward, and the sealing cylinder 11 is opened, allowing the gas to flow out smoothly. After exhalation, the breathing plate 13, the flow-blocking plate 14, and the mounting ring 12 cover the sealing cylinder 11 again under the action of gravity. When inhaling, the gas can only flow into the sealing cylinder 11 through the breathing hole 15. By sliding the flow-blocking plate 14, the number of breathing holes 15 can be changed, and the suction force required during inhalation can be adjusted to suit the use of lung cancer patients at different stages.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications and substitutions should be covered within the scope of the claims of the present invention.
