Description

Technical Field

[0001] This utility model relates to medical rehabilitation technology, and more particularly to a breathing training device for patients with cardiomyopathy during their rehabilitation period. Background Technology

[0002] Cardiomyopathy is a serious myocardial disease that affects the heart function of patients. During the rehabilitation period, scientific and systematic respiratory muscle training is of great significance for improving the cardiopulmonary function, enhancing exercise endurance and improving the quality of life. Specialized respiratory training devices provide controllable resistance to guide patients to perform deep and slow breathing, thereby exercising the strength and endurance of their respiratory muscles. They are key auxiliary devices in rehabilitation treatment.

[0003] However, some existing breathing training devices have limitations due to their crude adjustment mechanisms. For example, some devices use graded knobs or plug-in structures to change resistance, which have limited adjustment levels. Moreover, the resistance value is prone to fluctuations due to component wear or inaccurate positioning. This adjustment method makes it difficult to achieve smooth and linear resistance changes, which can easily lead to inconsistent training loads and fail to provide stable and repeatable training stimuli for patients at different stages of rehabilitation.

[0004] Therefore, it is necessary to design a breathing training device for patients with cardiomyopathy during their rehabilitation period to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of traditional breathing training devices that cannot achieve smooth resistance adjustment, the technical problem of this utility model is to provide a breathing training device for patients with cardiomyopathy during the rehabilitation period.

[0006] The technical implementation scheme of this utility model is as follows: A breathing training device for patients with cardiomyopathy during rehabilitation includes a breathing tube, a connecting block, an adjusting block, a first gear, a fixing block, a screw, a second gear, a slider, a sliding rod, a valve, and a helical spring. The upper part of the breathing tube has an exhalation channel, and the lower part has an inhalation channel. A connecting block is fixedly connected to the middle of the breathing tube, and an adjusting block is rotatably connected to the front side of the connecting block. First gears are fixedly connected to both sides of the adjusting block. A fixing block is fixedly connected to the middle of the exhalation channel of the breathing tube. A screw is rotatably connected to the left side of the fixing block, and a second gear is fixedly connected to the right side of the screw. A slider is threadedly connected to the screw, and the slider is slidably connected to the breathing tube. A sliding rod is fixedly connected to the left side of the slider, and a valve is slidably connected to the sliding rod. A helical spring connects the valve and the slider. The inhalation channel of the breathing tube is equipped with the same fixing block, screw, second gear, slider, sliding rod, valve, and helical spring, but all the components are oriented in opposite directions, and all the first gears mesh with the corresponding second gears.

[0007] More preferably, it also includes spring plates, with two spring plates fixedly connected to both the right side of the expiratory channel and the left side of the inspiratory channel of the breathing tube.

[0008] More preferably, it also includes a first baffle, a second baffle, and a mouthpiece. The first baffle is fixedly connected to the right side of the breathing tube, and the second baffle is rotatably connected to the first baffle. The mouthpiece is connected and communicates with the left side of the breathing tube.

[0009] More preferably, it also includes a shell, with the shell fixedly connected to the outside of the breathing tube.

[0010] More preferably, the outer shell is made of polycarbonate.

[0011] More preferably, the mouthpiece is made of medical-grade liquid silicone.

[0012] Beneficial effects: 1. This utility model achieves a precise and stable resistance adjustment effect by setting up a transmission and adjustment mechanism consisting of an adjustment block, a first gear, a second gear, a screw, a slider, and a valve. The user only needs to rotate the adjustment block to drive the screw to rotate through gear meshing, thereby controlling the linear movement of the slider to change the force required to blow the valve. This purely mechanical transmission method provides a smooth adjustment process and precise positioning, which can provide a stable and repeatable training load for patients at different rehabilitation stages. It effectively avoids the problems of rough adjustment and fluctuating resistance in traditional devices, ensuring the scientific nature and effectiveness of training.

[0013] 2. This utility model achieves a beneficial effect of providing real-time and clear training feedback by setting spring plates on the right side of the expiratory channel and the left side of the inspiratory channel. When the patient's breathing airflow reaches a certain intensity, it will blow open the spring plates to make a sound. This audible feedback mechanism can clearly indicate to the user whether the current breathing flow rate is up to standard, avoiding ineffective training due to insufficient inhalation volume, thereby improving the compliance and purposefulness of training.

[0014] 3. This utility model achieves a beneficial effect by providing auxiliary difficulty fine-tuning through the setting of a rotatable second baffle that cooperates with the first baffle. This structure provides an auxiliary means for resistance adjustment, allowing patients to make more detailed adjustments to the difficulty according to their own feelings, enriching the selection of training intensity gradients, and making rehabilitation training programs more personalized and adaptable.

[0020] Example: A breathing training device for patients with cardiomyopathy during their rehabilitation period, such as... Figures 1-4 As shown, the device includes a breathing tube 1, a connecting block 2, an adjusting block 3, a first gear 4, a fixing block 5, a screw 6, a second gear 7, a slider 8, a sliding rod 9, a valve disc 10, and a coil spring 11. The breathing tube 1 has an exhalation channel 101 at the top and an inhalation channel 102 at the bottom. The connecting block 2 is fused to the middle of the breathing tube 1. The adjusting block 3 is rotatably connected to the front of the connecting block 2. The first gear 4 is fixedly connected to both sides of the adjusting block 3. The fixing block 5 is fused to the middle of the exhalation channel 101 of the breathing tube 1. The screw 6 is rotatably connected to the middle of the left side of the fixing block 5. The second gear 7 is fixedly connected to the right side of the screw 6. A slider 8 is threaded onto the screw 6. The slider 8 is connected to the breathing tube. The channels 1 are slidably connected by a sliding groove. Sliding rods 9 are symmetrically welded to the left side of the slider 8. A valve disc 10 is slidably connected between the two sliding rods 9. Two helical springs 11 are connected between the valve disc 10 and the slider 8. The two helical springs 11 are respectively sleeved on the corresponding sliding rods 9. Each helical spring 11 is in a compressed state. The valve disc 10 and the breathing channel 1 are tightly fitted under the action of the helical springs 11. The breathing channel 102 of the breathing channel 1 is equipped with the same fixing block 5, screw 6, second gear 7, slider 8, sliding rod 9, valve disc 10 and helical spring 11, but all the components are oriented in opposite directions. All the first gears 4 are meshed with the corresponding second gears 7.

[0021] When using this device, the user first holds the outer casing 16 and places the left side of the breathing tube 1 into the mouth. The user can precisely adjust the resistance of the breathing training by rotating the adjustment block 3. When the user rotates the adjustment block 3 counterclockwise, the first gear 4, which is fixedly connected to its left and right sides, rotates synchronously. The first gear 4 and the second gear 7 mesh with each other, so the rotation of the first gear 4 will drive the second gear 7 and the screw 6 to rotate clockwise together. Since the slider 8 is slidably connected to the breathing tube 1 through the slide groove, the rotation of the corresponding screw 6 will drive the slider 8 away from the valve 10. During this process, the pressure on the helical spring 11 decreases, making it easier for the valve 10 to be sucked open or blown open, thereby reducing the difficulty of the training. If the difficulty needs to be increased, the adjustment block 3 is rotated clockwise. When performing breathing training, the user breathes through the left side of the breathing tube 1. The airflow will act on the valve 10, causing the valve 10 to be blown open. The user's inspiratory muscles must overcome this resistance to breathe, thereby achieving the training purpose.

[0022] like Figure 2 As shown, it also includes spring plates 12. Symmetrical spring plates 12 are fixedly connected to the right side of the exhalation channel 101 and the left side of the inhalation channel 102 of the breathing tube 1. The movable ends of every two symmetrical spring plates 12 abut against each other, as shown. Figure 1 and Figure 4 As shown, it also includes a first baffle 13, a second baffle 14, and a mouthpiece 15. The first baffle 13 is fused to the right side of the breathing tube 1, and the second baffle 14 is rotatably connected to the first baffle 13. The mouthpiece 15 is connected and communicates with the left side of the breathing tube 1. The mouthpiece 15 is made of medical-grade liquid silicone. Figure 1 As shown, it also includes a housing 16, which is fixedly connected to the outside of the breathing tube 1. The housing 16 is made of polycarbonate.

[0023] During breathing training, the user can exhale and inhale through the mouthpiece 15 into the breathing tube 1. The mouthpiece 15, made of medical-grade liquid silicone, provides a better user experience while ensuring safety during use. During breathing, the rated airflow blows the spring plate 12, causing its movable end to separate. When the gap between the spring plates 12 widens, the spring plates 12 will return to their original state under their own elasticity and then be blown open again by the airflow. This cycle repeats, and the spring plates 12 will maintain a high frequency of vibration, emitting a sound to clearly remind the user that the breathing training has been successful, avoiding insufficient inhalation that could lead to substandard training. During training, the user can rotate the second baffle 14 connected to the first baffle 13 to adjust the gap between the first baffle 13 and the second baffle 14, thereby changing the size of the exhalation and inhalation volume and further adjusting the difficulty of the training. The outer shell 16, made of polycarbonate, provides effective protection in the event of an accidental drop of the device.
