Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to a respiratory muscle training device. Background Technology
[0002] The incidence of chronic obstructive pulmonary disease (COPD) is significantly increased among the elderly, leading to decreased lung function and difficulty in expectorating phlegm. Current clinical solutions involve using a breathing trainer, which allows patients to inhale in cycles, causing small balls in the trainer to float upwards in sequence, thereby exercising the patient's respiratory muscles and lungs.
[0003] However, during the training process, it was found that the existing breathing trainer could not change the intensity of the airflow exhaled by the patient. The patient could only control the ball to maintain a certain height by adjusting the breathing rate to exercise the respiratory muscles and lungs. As the sensory system of the elderly weakens with age, it is difficult for elderly patients to accurately control the floating height of the ball, resulting in the problem of difficulty in controlling the intensity of respiratory muscle training. Utility Model Content
[0004] In order to solve the above problems, the purpose of this utility model is to provide a respiratory muscle training device, which aims to control the intensity of the airflow exhaled by the patient.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A respiratory muscle training device includes an air supply tube horizontally positioned in front of the patient's mouth, a training component vertically fixed to the rear end of the air supply tube, and an adjustment component positioned at the front end of the air supply tube for adjusting the intensity of respiratory airflow.
[0007] The training assembly includes a transparent barrel-shaped shell arranged along the height direction and whose lower sidewall is fixedly connected to the rear end of the gas supply pipe; a training ball movably disposed inside the transparent barrel-shaped shell; a support ring plate fixed to the inner wall of the transparent barrel-shaped shell and located above the connection between the transparent barrel-shaped shell and the gas supply pipe; a one-way exhaust valve fixed to the side wall between the support ring plate and the bottom of the inner wall of the transparent barrel-shaped shell and used to allow the gas inside the transparent barrel-shaped shell to flow unidirectionally to the external space; and a one-way inflation valve fixed to the connection between the transparent barrel-shaped shell and the gas supply pipe and used to allow the gas inside the gas supply pipe to flow unidirectionally into the transparent barrel-shaped shell.
[0008] The regulating assembly includes a rear fixed ring plate fixed to the front end of the gas delivery pipe, a control valve plate rotatably disposed at the front end of the rear fixed ring plate and having several airflow holes of different sizes spaced circumferentially, a front fixed ring plate rotatably disposed on the front side of the control valve plate, a sealing sheet fixed to the inner wall of the front fixed ring plate for allowing airflow to flow into the gas delivery pipe through a single airflow hole, a breathing tube fixed to the front of the front fixed ring plate, and an anti-detachment assembly disposed between the rear fixed ring plate and the control valve plate for preventing the control valve plate from detaching from the rear fixed ring plate.
[0009] More preferably, the anti-detachment component includes a limiting rail located in front of the rear fixed ring plate and a limiting member fixed to the rear side of the control valve plate and movably located within the limiting rail.
[0010] More preferably, a rotating dial is fixedly provided on the side wall of the control valve plate, and a wrapping element for wrapping the rotating dial is fixedly provided between the side walls of the rear fixed ring plate and the front fixed ring plate, and the wrapping element is provided with a dialing groove.
[0011] More preferably, the side wall of the gas supply pipe is connected to an air intake pipe, and the free port of the air intake pipe is fixed with an air intake one-way valve for allowing external air to flow unidirectionally toward the gas supply pipe.
[0012] More preferably, the front end of the breathing tube is provided with an air inlet.
[0013] More preferably, the outer wall of the transparent barrel-shaped shell is provided with scale lines along the height direction above the supporting ring plate.
[0014] This utility model has the following beneficial effects:
[0015] 1. This utility model adjusts the channel size when the patient blows in air by rotating the control valve plate, thereby adjusting the expiratory muscle strength required for the patient to blow the training ball to the same height when blowing in the same amount of gas into the transparent barrel shell. This solves the problem that existing breathing trainers are difficult to accurately control the intensity of respiratory muscle training.
[0016] 2. In this invention, when the patient inhales, external air is passed through the inhalation tube and then through the adjustment component before being inhaled into the lungs. This allows the adjustment component to change the respiratory muscle strength required for the patient to inhale, thereby further exercising the patient's lungs and respiratory muscles.

Gas flow direction. Detailed Implementation
[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a respiratory muscle training device in this embodiment includes an air supply tube 1 horizontally positioned in front of the patient's mouth, a training component 2 vertically fixed to the rear end of the air supply tube 1, and an adjustment component 3 positioned at the front end of the air supply tube 1 for adjusting the intensity of respiratory airflow.
[0026] The training component 2 includes a transparent barrel-shaped shell 21 arranged along the height direction and fixedly connected to the rear end of the gas supply pipe 1 on its lower side wall; a training ball 22 movably disposed inside the transparent barrel-shaped shell 21; a support ring plate 23 fixedly disposed on the inner wall of the transparent barrel-shaped shell 21 and located above the connection between the transparent barrel-shaped shell 21 and the gas supply pipe 1; a one-way exhaust valve 24 fixedly disposed on the side wall between the support ring plate 23 and the bottom of the inner wall of the transparent barrel-shaped shell 21 and used to allow the gas inside the transparent barrel-shaped shell 21 to flow unidirectionally to the external space; and a one-way inflation valve 25 fixedly disposed at the connection between the transparent barrel-shaped shell 21 and the gas supply pipe 1 and used to allow the gas inside the gas supply pipe 1 to flow unidirectionally into the transparent barrel-shaped shell 21.
[0027] The regulating assembly 3 includes a rear fixed ring plate 31 fixed to the front end of the air supply pipe 1, a control valve plate 32 rotatably disposed at the front end of the rear fixed ring plate 31 and having a plurality of airflow holes 33 of different diameters arranged circumferentially, a front fixed ring plate 34 rotatably disposed in front of the control valve plate 32, a sealing sheet 35 fixed to the inner wall of the front fixed ring plate 34 for allowing airflow to flow into the air supply pipe 1 through a single airflow hole 33, a breathing tube 36 fixed in front of the front fixed ring plate 34, and an anti-detachment assembly 37 disposed between the rear fixed ring plate 31 and the control valve plate 32 for preventing the control valve plate 32 from falling off the rear fixed ring plate 31.
[0028] When using this product, by rotating the control valve plate 32, the airflow hole 33 of an appropriate diameter is adjusted to be placed in the unobstructed area of the sealing plate 35. This causes the airflow exhaled by the patient to be affected by the airflow hole 33, slowing down the airflow and thus increasing the force required for the patient to exhale. As a result, the force required for the patient to blow the air into the transparent barrel-shaped shell 21 to blow up the training ball 22 is increased due to the influence of the airflow hole 33, thereby achieving the effect of precisely adjusting the intensity of the patient's exercise.
[0029] like Figure 1 and Figure 5 As shown, the anti-detachment assembly 37 includes a limiting rail 371 located in front of the rear fixed ring plate 31 and a limiting member 372 fixed to the rear side of the control valve plate 32 and movably located within the limiting rail 371.
[0030] When this product is in use, the limiting member 372 always moves within the limiting track 371 during the rotation of the control valve plate 32, thereby preventing the control valve plate 32 from falling off.
[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a rotating dial 4 is fixedly provided on the side wall of the control valve plate 32, and a wrapping member 5 is fixedly provided between the side walls of the rear fixed ring plate 31 and the front fixed ring plate 34 to wrap the rotating dial 4. The wrapping member 5 is provided with a dialing groove 51.
[0032] When using this product, the user inserts their finger into the actuation slot 51 and moves the corresponding rotating dial 4 at the actuation slot 51, causing the control valve plate 32 to rotate circumferentially. This allows the user to easily adjust the position of the airflow hole 33 and prevents accidental contact during use, which could cause the control valve plate 32 to rotate erroneously.
[0033] like Figure 1 , Figure 2 and Figure 3 As shown, an air intake pipe 6 is connected to the side wall of the air supply pipe 1, and an air intake check valve 61 is fixed at the free port of the air intake pipe 6 to allow external air to flow unidirectionally toward the air supply pipe 1.
[0034] When using this product, the patient keeps their mouth inside the mouthpiece 7 while inhaling, allowing external air to flow into the inhalation tube 6 through the one-way valve 61 and into the breathing tube 36 via the airflow hole 33 for the patient to absorb. The flow intensity of the inhaled gas is also affected by the airflow hole 33, allowing the patient's lungs and expiratory muscles to be exercised simultaneously during inhalation.
[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the front end of the breathing tube 36 is fitted with an air mouthpiece 7.
[0036] When using this product, a new mouthpiece 7 can be replaced by plugging and unplugging it to prevent bacterial infection caused by cross-use between different patients.
[0037] like Figure 1 , Figure 2 and Figure 3 As shown, the outer wall of the transparent barrel-shaped shell 21 has a scale line 8 along the height direction above the supporting ring plate 23.
[0038] When using this product, nursing staff can guide patients to blow the training ball 22 up to a certain height on the corresponding scale line and maintain it for a period of time to determine the recovery status of the patient's lungs and expiratory muscles, and then determine whether to replace it with a smaller diameter airflow hole 33 for further training.
[0039] The working principle of this device is as follows:
[0040] Step 1: Insert the clean inhalation nozzle 7 into the front end of the breathing tube 36. Then, the nursing staff adjusts the patient's expiratory muscle recovery by moving the rotating dial 4 in the dial 51 to drive the control valve plate 32 to rotate circumferentially.
[0041] Step 2: Rotate the control valve plate 32 until the airflow hole 33 suitable for the patient is rotated to the position where the sealing plate 35 is not blocked, so that the patient's oral cavity space and the internal space of the air supply tube 1 are connected through the corresponding airflow hole 33.
[0042] Step 3: The patient places their mouth against the inner wall of the inflator 7 and blows into it, causing the airflow to flow into the air delivery tube 1 through the airflow hole 33 and into the lower part of the transparent barrel-shaped shell 21 through the one-way inflation valve 25. This causes the training ball 22 to be affected by the impact of the incoming air, thus blowing it upward and making it float inside the transparent barrel-shaped shell 21. The patient and caregivers can observe the floating state of the training ball 22 through the outer wall of the transparent barrel-shaped shell 21, which makes it easier to judge the patient's expiratory muscle recovery status at this time.
[0043] Step 4: As air is continuously pumped into the lungs through the transparent barrel shell 21, excess gas is slowly expelled from the one-way exhaust valve 24. After the patient has completely blew air into their lungs, the training ball 22 descends within the transparent barrel shell 21 without being propelled by the gas and gets stuck on the support ring plate 23.
[0044] Step 5: When the patient inhales, the patient's mouth is kept inside the mouthpiece 7, and the patient inhales inward, so that the external air flows into the inhalation tube 6 through the one-way valve 61, and enters the breathing tube 36 through the airflow hole 33 for the patient to absorb. The flow intensity of the inhaled gas is also affected by the airflow hole 33, so that the patient's lungs and expiratory muscles can be exercised simultaneously during the inhalation process.
[0045] Step 6: After a certain training cycle, observe the patient's recovery by observing whether the patient blows the training ball 22 up to the height of the corresponding scale line 8 during one exhalation and maintains it for a period of time. If the recovery is good, the airflow hole 33 with a smaller diameter can be replaced for further training.
[0046] The above description is only a specific embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
