Description

Technical Field

[0001] This utility model relates to the field of pulmonary function rehabilitation technology, specifically to a pulmonary function rehabilitation device. Background Technology

[0002] A pulmonary function rehabilitation device is a medical device that helps improve lung function. For patients with weak respiratory muscles or those whose respiratory muscle function has declined due to prolonged bed rest or chronic diseases, pulmonary function rehabilitation devices can specifically exercise the respiratory muscles. For example, for patients with chronic obstructive pulmonary disease (COPD), using a rehabilitation device can alleviate respiratory muscle fatigue, enhance their contractile ability, and improve respiratory efficiency. Volume-type rehabilitation devices are particularly effective in increasing vital capacity. Whether the decline in vital capacity is due to aging or lung disease, regular use of a rehabilitation device can gradually increase lung ventilation. For example, some elderly people experience improved shortness of breath during daily activities such as climbing stairs after regular use.

[0003] Volumetric breathing trainers are a common type of pulmonary function rehabilitation device. However, common volumetric breathing trainers do not have adjustable resistance levels and cannot adjust the amount of breathing during training according to different stages of pulmonary function rehabilitation. Pulmonary function rehabilitation, like exercise, requires a gradual approach. In addition, some breathing trainers require manual operation of the knob for resistance adjustment, and manual switching of the usage mode and air intake / exhaust for exhalation and inhalation. This is very cumbersome and complicated for the elderly and young children. Therefore, we propose a pulmonary function rehabilitation device. Utility Model Content

[0004] The purpose of this invention is to provide a pulmonary function rehabilitation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pulmonary function rehabilitation device, comprising a breathing trainer, characterized in that: a sleeve is fixedly installed inside the breathing trainer, a limiting rod is fixedly connected inside the sleeve, a slider is slidably contacted between the sleeve and the limiting rod, a buffer mechanism is provided below the slider, an impeller mechanism is provided below the buffer mechanism, and a fixing rod is also fixedly connected inside the sleeve.

[0006] Preferably, the sleeve sidewall has four elongated holes for gas flow.

[0007] Preferably, the side wall of the limiting rod is provided with a spiral groove.

[0008] Preferably, the slider is equipped with a protrusion for sliding within the spiral groove, and the slider is also provided with a square hole.

[0009] Preferably, the buffer mechanism includes a spring sleeve, which is fixedly connected to the slider. A buffer plate is fixedly connected to the spring sleeve, and a spring is fixedly connected to the buffer plate. A buffer pad is fixedly installed on the bottom side of the buffer plate, and a square rod is also fixedly installed on the buffer plate. The square rod and the slider slide in contact through a square hole.

[0010] Preferably, the impeller mechanism includes a support, the support is fixedly connected to the buffer plate, and the support is rotatably connected to blades.

[0011] Preferably, the upper end of the square rod is a block with a large outer diameter, and the upper end diameter of the square hole is the same as the outer diameter of the block, ensuring that the square rod and the slider will not separate and maintaining airtightness.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, by incorporating a sleeve with an elongated hole, a limiting rod with a spiral groove, and a slider with protrusions, allows users to control their breathing rate and force to counteract different resistances of the pulmonary function rehabilitation device at different stages of pulmonary function rehabilitation, without the need for manual operation of the knob to adjust the device.

[0014] This utility model is equipped with an impeller mechanism. When the blade is subjected to airflow pressure, it will rotate counterclockwise and contact the buffer pad to ensure smooth airflow. It is also fixedly connected to the slider. As the slider slides upward and rotates counterclockwise around the limit rod, it generates a downward airflow force, providing effective airflow resistance.

[0015] This invention incorporates a buffer mechanism that reduces the impact force of the blades when they rotate upwards and contact the buffer pad, preventing the device from being easily damaged by impact due to its lightweight material. Attached Figure Description

Detailed Implementation

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a pulmonary function rehabilitation device, including a breathing trainer 1. Sleeves 2 are fixedly installed on the exhalation and inhalation pipes of the breathing trainer 1. Four elongated holes 21 are formed on the side wall of the sleeve 2 for gas flow. A limiting rod 3 is fixedly connected inside the sleeve 2. A spiral groove 31 is formed on the side wall of the limiting rod 3. A slider 4 is also provided between the sleeve 2 and the limiting rod 3. The slider 4 has an inner hole at its center, through which the limiting rod 3 passes. A [missing information - likely a device name or design element] is installed on the side wall of the inner hole. The protrusion 41, when the slider 4 is subjected to sufficient air pressure, slides within the spiral groove 31 and rotates the slider 4. A square hole 42 is also provided on the slider. A buffer mechanism 5 is provided below the slider 4. The buffer mechanism 5 includes a spring sleeve 51, which is fixedly connected to the slider 4. A buffer plate 52 is also fixedly connected to the spring sleeve 51. A spring 53 is fixedly connected to the buffer plate 52. The spring 53 is made of lightweight plastic rather than metal. A buffer pad 54 is fixedly installed on the bottom side of the buffer plate 52. The buffer pad 54 is made of foamed rubber and plastic material. A square rod 55 is also fixedly installed on the buffer plate 52. The square rod 55 and the slider 4 slide in contact through a square hole 42. The square rod 55 is composed of two coaxial cuboids, with the upper end being a large-diameter block. The square hole 42 consists of two coaxial square holes, ensuring that the square rod 55 and the slider 4 will not detach. Furthermore, the upper diameter of the square hole 42 is the same as the outer diameter of the block, maintaining airtightness. An impeller mechanism 6 is installed below the buffer mechanism 5. The impeller mechanism 6 includes a support 61. 61 is fixedly connected to the buffer plate 52. The support 61 is rotatably connected to the blade 62. The vertical distance between the blade 62 and the buffer pad 54 is less than half the length of the widest part of the blade. There is a limit plate on one side of the blade 62. The blade 62 can only rotate counterclockwise to one side. A fixing rod 7 is also fixedly connected inside the sleeve 2. The fixing rod 7 is used to prevent the slider 4, the buffer mechanism 5 and the impeller mechanism 6 from falling out of the sleeve. It is also worth noting that the material of the above devices is similar to that of the small ball of the breathing trainer. They are all lightweight plastics.

[0022] Working principle: When the user is in the early stage of rehabilitation and in a weak stage, when using the pulmonary function rehabilitation device, control the intensity of breathing, keep the impeller mechanism 6 and slider 4 stationary, and only control the small ball of the breathing trainer 1 to rise. When the small ball rises to the top, the rate of lung capacity in and out is about 600cc per second.

[0023] When the user is in the late stage of rehabilitation and has a certain foundation of lung function, they can exhale and blow air slightly to counteract the air pressure while ensuring that the small ball of the breathing trainer 1 rises to the top. This causes the blades 62 to be lifted from a horizontal position by the airflow. The blades 62 will then rotate and tilt, and then contact the buffer pad 54. The buffer pad 54 can prevent damage to the blades 62. The buffer mechanism 5 buffers the impact force on the blades 62. Then the airflow will push the slider 4 upward through the gaps between the blades 62. Under the restriction of the protrusion 41, the slider 4 rotates counterclockwise upward along the spiral groove 31 on the limit rod 3. More and more of the area of ​​the elongated hole 21 on the sleeve 2 is located at the lower end of the slider 4. The airflow rate from the elongated hole 21 will continuously increase from zero, and the impeller mechanism 6 will rotate upward with the slider 4. Since the blades 62 maintain a counterclockwise tilt angle, airflow resistance will be generated downward during the counterclockwise rotation of the blades 62. When the slider 4 rises to the top of the sleeve 2, the rate of lung capacity in and out is approximately 1500cc per second.
