Description

Technical Field

[0001] This utility model relates to a compact breathing trainer, belonging to the technical field of breathing training equipment. Background Technology

[0002] Chronic obstructive pulmonary disease (COPD) is a common chronic respiratory disease. Patients often experience breathing difficulties and decreased exercise tolerance, which affect their quality of life due to airway obstruction and decreased lung function. To improve patients' respiratory function, in addition to medication, clinical practice usually involves using respiratory rehabilitation equipment such as breathing trainers for respiratory rehabilitation training. Breathing training includes inspiratory muscle training and expiratory resistance training.

[0003] Currently, respiratory trainers mainly fall into two categories: one is the more complex multifunctional respiratory trainer, which is generally large and difficult to operate, making it inconvenient for patients to carry around and use long-term; the other is the simple respiratory trainer, which typically changes breathing resistance by adjusting the size of the airway, but can only roughly control the size of the airflow channel, making it difficult to achieve precise and independent adjustment of expiratory and inspiratory pressures. However, in actual rehabilitation training, the required settings for expiratory and inspiratory pressures often differ. For example, some patients need greater resistance during inhalation to strengthen inspiratory muscles, while needing lower pressure during exhalation to reduce the burden of exhalation. Because existing devices cannot simultaneously and independently adjust both pressures within a small size, it is difficult to achieve high-quality respiratory training when out and about.

[0004] Therefore, there is an urgent need for a respiratory trainer that is compact, portable, and capable of independently adjusting expiratory and inspiratory pressures to meet the training needs of COPD patients and other respiratory training populations. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a compact breathing trainer that solves the problem that current simple breathing trainers cannot independently and steplessly adjust the expiratory and inspiratory pressures.

[0006] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0007] A compact breathing trainer includes:

[0008] A sleeve, one end of which is provided with an end face having a hollow hole and an air outlet, and the other end is connected to an air nozzle;

[0009] An outer end cap is screwed to one end of the hollow hole of the sleeve. The outer end cap has a hollow hole and a first magnetic ring is installed inside the outer end cap.

[0010] The inner cylinder has a magnetic baffle at one end. The magnetic baffle has an installation hole and an air inlet. The inner cylinder is fitted into the hollow hole. The magnetic baffle repels the first magnetic ring and seals the air outlet.

[0011] A baffle plate is fixedly attached to a sliding rod. The sliding rod on one side of the baffle plate is slidably installed in the mounting hole, and a magnetic plate is installed on the sliding rod on the other side of the baffle plate. The magnetic plate repels the second magnetic ring installed inside the inner cylinder, and the baffle plate seals the air inlet.

[0012] Preferably, the outer wall of the sleeve is provided with expiratory pressure scale lines along the axial direction.

[0013] Preferably, the outer end of the slide bar is provided with a flexible limiting cone block whose maximum outer diameter is larger than the inner diameter of the mounting hole.

[0014] Preferably, the second magnetic ring is fixed to the end of the adjusting cylinder, and the adjusting cylinder is screwed to the inner wall of the inner cylinder.

[0015] Preferably, the regulating cylinder is provided with suction pressure scale lines along the axial direction.

[0016] Preferably, the side of the magnetic baffle facing the air outlet is covered with an exhalation sealing gasket.

[0017] Preferably, the side of the baffle facing the air inlet is covered with an air intake sealing gasket.

[0018] Preferably, the air nozzle is screwed onto the sleeve.

[0019] Preferably, the magnetic baffle and the magnetic sheet are mutually repulsive.

[0020] Preferably, the air nozzle is provided with a groove to facilitate engagement.

[0021] The beneficial effects of this utility model are:

[0022] 1. Utilizing the principle of magnetic repulsion and the nonlinear change of magnetic force, the pressure exerted by the magnetic baffle at the air outlet by adjusting the distance between the first magnetic ring and the inner cylinder is changed. During exhalation, the pressure exerted by the magnetic force is overcome, thus achieving stepless adjustment of exhalation pressure.

[0023] 2. Similarly, by adjusting the distance between the second magnetic ring and the magnetic plate, the pressure of the magnetic plate and the baffle at the air inlet is changed. When inhaling, the pressure applied by the magnetic force is overcome, and stepless adjustment of the inhalation pressure is achieved. Moreover, the adjustment of inhalation pressure and the adjustment of expiration pressure are independent of each other.

[0024] 3. This breathing trainer is compact, portable, easy to disassemble and install, and easy to disinfect and clean its internal parts, making it suitable for reuse. Attached Figure Description

[0035] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0036] like Figure 1 , Figure 2 As shown, this compact breathing trainer is suitable for COPD patients and other people who need breathing training, especially those who need to carry it with them and perform breathing training anytime. It includes a sleeve 1, an outer end cap 2 screwed to the end of the sleeve 1, an inner cylinder 3 built into the sleeve 1 to block the air outlet 104, and a baffle 4 to block the air inlet 303 on the inner cylinder 3.

[0037] like Figure 1 , Figure 2As shown, the sleeve 1 is made of medical-grade plastic. One end of the sleeve 1 is closed by an end face 101, and the other end is connected to an air nozzle 102. The end face 101 has a hollow hole 103 and multiple air outlet holes 104 surrounding the hollow hole 103. The air outlet holes 104 are evenly distributed around the hollow hole 103. External threads 105 are provided on the outer walls of both ends of the sleeve 1. The two ends of the sleeve 1 are fixed to the air nozzle 102 and the outer end cap 2 respectively by the external threads 105.

[0038] like Figure 1 , Figure 2 As shown, the outer end cap 2 is screwed onto one end of the hollow hole 103 of the sleeve 1. The outer end cap 2 is provided with a hollow hole 201 for air intake and exhaust. The inner end face 101 of the outer end cap 2 is fixed with a first magnetic ring 202 by glue. The outer end cap 2 is made of medical plastic material.

[0039] like Figures 2-4 As shown, the inner cylinder 3 is made of medical-grade plastic. One end of the inner cylinder 3 has a magnetic baffle 301, larger than the outer diameter of the inner cylinder 3 but smaller than the inner diameter of the outer end cap 2, to allow for an exhaust gap between the magnetic baffle 301 and the outer end cap 2. The magnetic baffle 301 has a mounting hole 302 in the middle and multiple air inlets 303 communicating with the interior of the inner cylinder 3. The inner cylinder 3 is fitted into the hollow hole 103. The magnetic baffle 301 repels the first magnetic ring 202, thus sealing the air outlet 104. The magnetic baffle 301 and the first magnetic ring 202 are made of neodymium magnets. Rotating the outer end cap 2 adjusts the distance between the magnetic baffle 301 and the first magnetic ring 202, thereby adjusting the magnitude of the repulsive force. This repulsive force, transmitted to the magnetic baffle 301, compresses and seals the air outlet 104, achieving expiratory pressure regulation.

[0040] like Figures 2-5As shown, the baffle 4 is made of medical-grade plastic. The outer diameter of the baffle 4 is smaller than the inner diameter of the inner cylinder 3 so that there is a gap for air intake between the baffle 4 and the inner cylinder 3. A plastic sliding rod 401 is coaxially fixed in the middle of the baffle 4. The outer wall of the sliding rod 401 is smooth, which is conducive to the free sliding of the baffle 4 back and forth. The sliding rod 401 on one side of the baffle 4 is slidably installed in the mounting hole 302. A magnetic sheet 402 is installed on the sliding rod 401 on the other side of the baffle 4. There is an anti-interference distance between the magnetic sheet 402 and the baffle 4 formed by the extended sliding rod 401. This anti-interference distance requires that the influence of the first magnetic ring 202 and the magnetic baffle 301 on the magnetic sheet 402 is much smaller than the influence of the second magnetic ring 403 on the magnetic sheet 402. The magnetic baffle 301 and the magnetic plate 402 are mutually repulsive, allowing the starting point of the inhalation pressure adjustment range to be 0 (i.e., the resultant force of the repulsive forces on the magnetic plate 402 along its axis, primarily from the second magnetic rings 403 and the magnetic baffle 301, is close to 0). This arrangement ensures that the inhalation and exhalation pressure adjustments remain as independent as possible. The magnetic plate 402 repels the second magnetic ring 403 installed inside the inner cylinder 3, and the baffle 4 seals the air inlet 303. The magnetic plate 402 and the second magnetic ring 403 are neodymium magnets.

[0041] Utilizing the principle of magnetic repulsion and the nonlinear characteristics of magnetic force, the adjustment distance can be shortened. Compared to the excessive space required by existing methods using springs and related connections, this pressure adjustment structure allows for a more compact overall breathing trainer and enables independent adjustment of expiratory and inspiratory pressures. By adjusting the distance between the first magnetic ring 202 and the magnetic baffle 301 of the inner cylinder 3, the pressure exerted by the magnetic baffle 301 at the air outlet 104 is changed. During exhalation, the pressure exerted by the magnetic force is overcome, thus regulating the expiratory pressure. Similarly, by adjusting the distance between the second magnetic ring 403 and the magnetic plate 402, the pressure exerted by the magnetic plate 402 and the baffle 4 at the air inlet 303 is changed. During inhalation, the pressure exerted by the magnetic force is overcome, thus regulating the inspiratory pressure.

[0042] like Figure 2 As shown, in some embodiments, the outer wall of the sleeve 1 is provided with expiratory pressure scale lines 106 along the axial direction. The expiratory pressure scale lines 106 are non-linear, and the interval between scale values ​​is obtained by pre-testing.

[0043] The second magnetic ring 403 is fixed to the end of the adjusting cylinder 304. The end of the adjusting cylinder 304 is provided with a raised stepped threaded portion 305, which is screwed to the inner wall of the inner cylinder 3. The adjusting cylinder 304 is provided with suction pressure scale lines 306 along the axial direction. The suction pressure scale lines 306 are non-linear, and the scale value intervals or levels are obtained by pre-testing.

[0044] Based on the above embodiments, the respiratory pressure value can be adjusted more accurately by relying on the scale lines:

[0045] 1. Expiratory pressure adjustment: Hold the sleeve 1 firmly with one hand and rotate the outer end cap 2 with the other hand to adjust the distance between the magnetic baffle 301 and the first magnetic ring 202. Determine the current expiratory pressure value based on the reading at the end of the outer end cap 2 located at the expiratory pressure scale line 106 on the sleeve 1.

[0046] 2. Inhalation pressure adjustment: Remove the outer end cap 2, pull out the inner cylinder 3, hold the adjusting cylinder 304 with one hand, and rotate the inner cylinder 3 with the other hand to adjust the distance between the magnetic plate 402 and the second magnetic ring 403. Determine the current inhalation pressure value based on the reading at the inhalation pressure scale line 306 at the end of the inner cylinder 3 located on the adjusting cylinder 304.

[0047] like Figure 2 , Figure 3 , Figure 5 As shown, in some embodiments, a flexible limiting cone block 404 with a maximum outer diameter larger than the inner diameter of the mounting hole 302 is provided at the outer end of the slide rod 401. The flexible limiting cone block 404 prevents the baffle 4 from falling off by pressing through the mounting hole 302.

[0048] like Figures 2-4 As shown, in some embodiments, the side of the magnetic baffle 301 facing the air outlet 104 is covered with an exhalation sealing gasket 307. The side of the baffle 4 facing the air inlet 303 is covered with an inhalation sealing gasket 405. The exhalation sealing gasket 307 and the inhalation sealing gasket 405 can better seal and isolate the air outlet 104 and the air inlet 303.

[0049] like Figure 2 As shown, in some embodiments, the nozzle 102 is provided with a groove 107 for easy biting. When the nozzle 102 of the breathing trainer is placed in the mouth, the bite groove 107 makes it more secure and prevents it from falling out.

[0050] like Figure 4 , Figure 5 As shown, the exhalation and inhalation states of this compact breathing trainer are:

[0051] 1. Exhalation state ( Figure 4 ): Utilizing the principle of magnetic repulsion, in the initial state, the magnetic baffle 301 is pressed against the outside of the air outlet 104 by the first magnetic ring 202 at a preset pressure; when the patient exhales, the gas enters the interior through the air nozzle 102, overcomes the preset exhalation pressure value, and pushes the magnetic baffle 301 at the air outlet 104 to form an exhaust channel, and finally the gas is discharged from the hollow hole 201 of the outer end cover 2; during this process, the baffle 4 always closes the air inlet 303.

[0052] 2. Inhalation state ( Figure 5): Utilizing the principle of magnetic repulsion, in the initial state, the magnetic sheet 402 is pressed against the inside of the air inlet 303 by the second magnetic ring 403 according to a preset pressure; when the patient inhales, the gas enters the interior through the hollow hole 201 of the outer end cover 2, overcomes the preset inhalation pressure value, and pushes the baffle 4 at the air inlet 303 to form an air intake channel, and finally the gas enters the human oral cavity from the air nozzle 102; during this process, the magnetic baffle 301 always closes the air outlet 104.

[0053] This breathing trainer is not only easy to adjust and use, but also compact and portable. It is also easy to disassemble and install, and the internal parts are easy to disinfect and clean, which is conducive to reuse.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
