Description

Technical Field

[0001] The present invention particularly relates to a safe lung function rehabilitation training device. Background Art

[0002] Pulmonary function rehabilitation training equipment, used in conjunction with a ventilator, has become an important means of training and restoring lung function for patients with chronic obstructive pulmonary disease and respiratory dysfunction. With this type of equipment, patients can perform breathing exercises under controlled conditions, gradually strengthening their respiratory muscles, improving lung ventilation, and enhancing rehabilitation outcomes. For example, the Chinese invention patent with publication number CN117547789A provides a lung function breathing exercise device that realizes adjustable resistance and vibration frequency for lung function training. Combined with a ventilator, it avoids the tediousness of switching equipment. By real-time monitoring of tidal volume, it provides instant feedback on the patient's respiratory status, helps personalized treatment, and also facilitates saliva cleaning.

[0003] However, most pulmonary function rehabilitation training devices currently on the market lack protective mechanisms when connected to a ventilator for pulmonary function training. During training, hypoxia may occur due to individual patient differences, changes in condition, or inappropriate training intensity.

[0004] However, existing equipment cannot accurately monitor a patient's blood oxygen status in real time, nor does it provide effective measures to quickly restore ventilation to maximum capacity when hypoxia occurs. Once hypoxia occurs, the equipment cannot adjust ventilation parameters in a timely manner, which can easily lead to insufficient oxygen supply and the subsequent danger of hypoxia. This not only affects the effectiveness of rehabilitation training but can also pose a serious threat to the patient's life and health. Summary of the Invention

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0021] Example: like Figure 1As shown, the present application provides a safe lung function rehabilitation training equipment, including a breathing mask 1, the breathing mask 1 is provided with an air outlet check valve 2 and a mounting pipe 4, the mounting pipe 4 is provided with an air inlet pipe 5 connected with the breathing machine pipe.In use, the breathing mask 1 can be fixed on the face of the patient through the binding band, and the air inlet pipe 5 is connected with the breathing machine, and the patient can inhale oxygen through the breathing mask 1 without exercise.

[0022] As shown, Figures 3 to 6 In this embodiment, the mounting pipe 4 is rotatably sleeved with a driving cylinder 13, the driving cylinder 13 is provided with a shielding assembly located in the mounting pipe 4, and the rotation of the driving cylinder 13 is converted into the shielding of the cross section of the mounting pipe 4 with adjustable area through the shielding assembly, the shielding assembly includes a first baffle 7 provided in the mounting pipe 4, a plurality of arc-shaped first air grooves 8 are formed in the first baffle 7, a second baffle 15 is rotatably arranged in the mounting pipe 4 along the axis line thereof, the second baffle 15 is fixedly connected with the driving cylinder 13, and a plurality of arc-shaped second air grooves 16 are formed in the second baffle 15.

[0023] The mounting pipe 4 is provided with a through groove 6, the second baffle 15 is provided with a connecting block 14, the connecting block 14 is slidingly clamped in the through groove 6 and connected with the driving cylinder 13.The driving cylinder 13 can drive the connecting block 14 to slide in the through groove 6 when rotating, and then drive the second baffle 15 to rotate through the connecting block 14.The first air groove 8 and the second air groove 16 coincide when the driving cylinder 13 is located at the initial position, and the first baffle 7 and the second baffle 15 shield the second air groove 16 and the first air groove 8 respectively when the driving cylinder 13 rotates, so that the greater the angle of the driving cylinder 13 rotates, the greater the resistance of the first air groove 8 and the second air groove 16, and the greater the lung function exercise intensity.

[0024] As shown, Figures 3 to 6 In this embodiment, the breathing mask 1 is rotatably provided with a winding wheel 26, the winding wheel 26 is wound with a pull rope 29, and the pull rope 29 is connected with the driving cylinder 13 and the mounting pipe 4 through a connecting mechanism to control the driving cylinder 13 to rotate at different angles when the pull rope 29 is pulled for multiple times, and to control the driving cylinder 13 to reset when the pull rope 29 is loosened.The connecting mechanism includes a driving assembly provided on the winding wheel 26 and connected with the driving cylinder 13, which converts the rotation of the winding wheel 26 into the control of the rotation of the driving cylinder 13, and the driving assembly includes a first gear 27 provided on the winding wheel 26 and a second gear 17 provided on the driving cylinder 13, the second gear 17 is engaged with the first gear 27.

[0025] The winding wheel 26 can be driven to rotate by pulling the pull rope 29. During the rotation process, the winding wheel 26 drives the driving cylinder 13 to rotate through the engagement of the first gear 27 and the second gear 17, thereby controlling the rotation of the second baffle 15 to block the air flow section.

[0026] like Figures 3 to 6 As shown, in this embodiment, the connecting mechanism also includes a limiting component arranged on the driving cylinder 13 and connected to the mounting tube 4, and the limiting component is used to limit the driving cylinder 13 to different distances each time it rotates. The limiting component includes a mounting frame 18 arranged on the peripheral side of the driving cylinder 13, and a sliding seat 20 is provided on the mounting frame 18 for sliding along the axis of the driving cylinder 13. A first elastic member 24 is provided between the sliding seat 20 and the inner wall of the mounting frame 18, and a driving shaft 21 is provided on the sliding seat 20 for sliding along its axis. A retaining ring 22 is provided on the driving shaft 21, and a second elastic member 23 is provided between the retaining ring 22 and the sliding seat 20. A guide rail is provided on the mounting tube 4, and the end of the driving shaft 21 is clamped in the guide rail, and the movement of the driving shaft 21 is limited to different distances by the guide rail. The guide rail includes a first rail 10, a second rail 11 and a flat rail 12. The first rails 10 are arranged in parallel in multiple groups and are arranged on the mounting tube 4. The lengths of the multiple groups of first rails 10 increase successively. The second rails 11 are provided in multiple groups, and their two ends are respectively connected to the departing ends of the two adjacent groups of first rails 10 in a stepped manner. The flat rail 12 is connected to the end of a group of first rails 10 closest to the breathing mask 1 and the end of a group of second rails 11 farthest from the breathing mask 1.

[0027] In the initial state, the end of the drive shaft 21 is secured to the end of the flat rail 12 near the respiratory mask 1. The initial pull of the pull cord 29 rotates the drive cylinder 13, causing the drive shaft 21 to slide into the first rail 10. Under the action of the second elastic member 23, the drive shaft 21 passes through a step at the end of the first rail 10 and enters the connected set of second rails 11, driving the second baffle 15 to rotate a certain angle. When the drive cylinder 13 reverses, the step blocks the end of the drive shaft 21, preventing it from moving along its original trajectory. This allows it to slide along the second rail 11 until it passes through the step at the end of the second rail 11 and enters the next set of first rails 10. This continues in this order. Because each set of first rails 10 has a different length, each pull of the pull cord 29 controls the rotation distance of the drive cylinder 13, achieving multi-level adjustment of the pulmonary function training intensity. Each pull of the pull cord 29 causes the sliding seat 20 to slide a certain distance along the mounting frame 18, compressing the first elastic member 24. When the driving shaft 21 slides into the end of the last set of second rails 11 , the sliding seat 20 is controlled to slide along the flat rail 12 and return to the end of the first rail 10 under the action of the first elastic member 24 .

[0028] like Figure 1 、 2As shown in Figures 7 and 7, in this embodiment, a protective cover 3 is provided on the respiratory mask 1, a connecting mechanism is provided inside the protective cover 3, and a pull rope 29 extends out of the protective cover 3. The protective cover 3 protects the relevant components, thereby improving the service life of the device. The connecting mechanism also includes a reset assembly provided on the driving cylinder 13 and connected to the respiratory mask 1, which drives the winding wheel 26 to reset after the pull rope 29 is released. The reset assembly includes a coil spring 28 and a tension spring 25. The coil spring 28 is sleeved on the winding wheel 26, and one end thereof is fixedly connected to the winding wheel 26, and the other end is fixedly connected to the protective cover 3. A first connecting column 9 is provided on the respiratory mask 1, and a second connecting column 19 is provided on the driving cylinder 13. The two ends of the tension spring 25 are respectively connected to the first connecting column 9 and the second connecting column 19.

[0029] When the pull cord 29 is pulled to rotate the winding wheel 26 and the drive drum 13, the winding wheel 26 causes the coil spring 28 to deform, and the drive drum 13 stretches the tension spring 25. When the pull cord 29 is released, the coil spring 28 and the tension spring 25 respectively control the resetting of the winding wheel 26 and the drive drum 13. This ensures that regardless of the training intensity level, after releasing the pull cord 29, the drive shaft 21 can be reset and close to the flat rail 12, so that the second baffle 15 is reset to ensure maximum ventilation. The distance between the flat rail 12 and the top of the first rail 10 is small, so the deviation in the blocked area of ​​the second baffle 15 during rotation is negligible.

[0030] like Figure 7 As shown, in this embodiment, a pull rod 30 is provided at the end of the pull cord 29, and the circumference of the pull rod 30 is concave. The configuration of the pull rod 30 in this shape makes it easier to pull the pull cord 29, and when the patient is weak due to hypoxia, the pull rod 30 can be quickly released to restore maximum ventilation.

[0031] Specific usage and beneficial effects of the present invention: When the pulmonary function rehabilitation training device is in use, the upper air inlet pipe 5 is connected to the pipe of the ventilator. The patient can breathe through the breathing mask 1 when not exercising. When exercising, the winding wheel 26 can be driven to rotate by pulling the pull rope 29. When the winding wheel 26 rotates, the driving cylinder 13 is driven to rotate through the connecting mechanism. The rotation angle of the driving cylinder 13 is different each time the pull rope 29 is pulled. During the rotation process, the driving cylinder 13 blocks the cross section of the mounting tube 4 through the shielding assembly. The larger the rotation angle of the driving cylinder 13, the larger the area of ​​the cross section of the mounting tube 4 that is blocked. The breathing resistance is adjusted by controlling the cross section of the air flow in the mounting tube 4 to achieve controllable exercise intensity. When the pull rope 29 is loosened, the driving cylinder 13 can be controlled to reset under the action of the connecting mechanism, and the shielding assembly is reset to ensure maximum ventilation. Therefore, when the patient suffers from hypoxia during exercise, the patient can automatically and quickly recover to the maximum ventilation, effectively avoiding the danger caused by hypoxia.

[0032] The basic principles, main features, and advantages of the present invention are shown and described above. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above. Modifications and improvements may be made based on the present invention, as will be apparent to those skilled in the art. Therefore, such modifications and improvements, without departing from the spirit of the present invention, are intended to fall within the scope of protection claimed in the present invention.
