Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a lung function training device. Background Technology
[0002] In respiratory rehabilitation and pulmonary function training, respiratory training devices with floats or floats are often used. The floats are raised by the patient's exhalation to train and monitor indicators such as vital capacity and respiratory flow rate.
[0003] However, most existing devices have fixed airflow channel cross-sectional areas and float weights, making it impossible to flexibly adjust training intensity structurally. While some products achieve some degree of intensity adjustment by changing channel resistance or adjusting float weight, the adjustment range is limited. Once the patient's lung function recovers to a certain level, the resistance provided by the original device becomes insufficient, and the float is easily blown to its highest point, resulting in reduced training effectiveness and a shorter usage period. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides a lung function training device.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A lung function training device, comprising:
[0007] The main body of the device is used for patients to perform lung function training, and it has a channel for gas flow inside.
[0008] The diverter is rotatably mounted on the top of the device body. One end of the diverter extends from the outside of the device body to the inside of the device body. Initially, the direction of its free end is approximately the same as the direction of gas flow inside the device body.
[0009] A gas collection hood is installed at one end of the above-mentioned diversion pipe that extends into the device body, and is used to insert into the channel of the device body to form a gas interception surface.
[0010] The float is located inside the aforementioned diversion tube and can move along the length of the diversion tube as the gas flows within it.
[0011] When the free end of the diverter rotates around the device body in a vertical direction, the interception surface of the gas collecting hood inserted into the device body channel decreases, and the float rises higher when it moves the same length relative to the diverter.
[0012] Preferably, the angle between the aforementioned diverter and the gas flow channel within the device body is initially 5° to 10°, and when the aforementioned diverter rotates relative to the device body to its maximum angle, the angle between the aforementioned diverter and the gas flow channel within the device body is 60° to 90°.
[0013] Preferably, when the gas collecting hood rotates to its maximum angle with the diverter pipe, the area ratio of its effective interception surface to the initial effective interception surface is 3:1 to 4:1.
[0014] Preferably, one side of the gas collecting hood has a folded sealing cover for maintaining a sealed environment between the channel and the diversion pipe of the device body.
[0015] Preferably, the inner wall of the diversion tube is fixed with a baffle to limit the position of the float relative to the diversion tube.
[0016] Preferably, the float can move 80mm to 120mm relative to the diversion pipe.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] 1. By using the rotatable design of the diverter tube relative to the main body of the device, the effective interception area of the gas collection hood in the channel of the main body of the device can be changed. Thus, without changing the float or the channel size, the air flow rate and the difficulty of the float can be adjusted in multiple levels to meet the lung function training needs of different rehabilitation stages.
[0019] 2. When the shunt tube is rotated to a larger angle, the float needs to overcome a larger component of gravity under the same displacement, thereby significantly increasing the training intensity, extending the effective service life of the device in the patient's rehabilitation cycle, and avoiding the problem of insufficient resistance in the later training of the existing device.

[0028] Example
[0029] like Figures 1-3 As shown, a lung function training device includes components such as a device body 1, a diversion tube 2, an air collection hood 21, and a float 23.
[0030] In one embodiment, such as Figures 2-3 As shown, the device body 1 is used for patients to perform lung function training, and it has a channel for gas flow inside. This channel can form a stable airflow path when the patient exhales, so as to drive the subsequent structures to work normally. An air blowing tube 11 is provided on one side of the device body 1 for the patient to blow air.
[0031] In one embodiment, such as Figures 2-3 As shown, the diverter tube 2 is rotatably mounted on the top of the device body 1. One end of the tube, near the rotating shaft, extends from the outside of the device body 1 into the inside of the device body 1. Initially, the direction of its free end extension is approximately the same as the direction of gas flow inside the device body 1, so that in the initial state, the gas can smoothly enter the interior of the diverter tube 2 and drive the float 23 to move.
[0032] In one embodiment, such as Figures 2-3 As shown, the gas collecting hood 21 is located at one end of the diversion tube 2 that extends into the device body 1, and is used to insert into the channel of the device body 1 to form a gas interception surface. When the patient exhales, part of the airflow in the device body 1 is intercepted by the gas collecting hood 21 and introduced into the diversion tube 2, which pushes the float 23 in the diversion tube 2 to move along the length direction.
[0033] In one embodiment, such as Figures 2-3 As shown, the float 23 is located inside the shunt tube 2 and can move along the length of the shunt tube 2 along with the gas flow within it. When the free end of the shunt tube 2 rotates vertically around the device body 1, the effective interception surface of the gas collection hood 21 inserted into the channel of the device body 1 decreases, thereby reducing the airflow entering the shunt tube 2. The float 23 needs to overcome a greater component of gravity for the same length displacement, resulting in the patient requiring higher expiratory pressure and flow rate to bring the float 23 to the same height. This structure allows for a significant increase in training intensity through simple rotational adjustment, adapting to the training needs of patients at different rehabilitation stages.
[0034] In one embodiment, such as Figures 2-3 As shown, initially, the angle between the shunt tube 2 and the gas flow channel within the device body 1 is 5°~10°. When the shunt tube 2 is rotated relative to the device body 1 to its maximum angle, the angle between the shunt tube 2 and the gas flow channel within the device body 1 is 60°~90°. Initially, the flow path resistance of the airflow entering the shunt tube 2 is minimal, suitable for low-intensity training for patients in the early stages of rehabilitation. When it is necessary to increase the training intensity, the shunt tube 2 can be rotated around the axis to the maximum angle of 60°~90°. At this time, the angle between the airflow interception direction and the direction of gravity increases significantly, and the float 23 requires more expiratory power support during its ascent, suitable for high-intensity training for patients whose lung function has significantly recovered. By setting the angle range, it is possible to cover the entire stage of training from low to high intensity while ensuring the precision and controllability of the adjustment process.
[0035] In one embodiment, such as Figures 2-3 As shown, when the air collection hood 21 rotates to its maximum angle with the diverter pipe 2, the area ratio of its effective interception surface to the initial effective interception surface is 3:1 to 4:1. By changing this interception area ratio, the amount of airflow interception can be directly controlled before the airflow enters the diverter pipe 2. Combined with the angle adjustment of the diverter pipe 2, the thrust on the float 23 changes more significantly, thereby achieving multi-level adjustable training intensity.
[0036] In one embodiment, such as Figures 2-3 As shown, one side of the gas collecting hood 21 has a folded sealing cover 22 for maintaining a sealed environment between the channel of the device body 1 and the diversion pipe 2. This folded sealing cover 22 can maintain a sealed environment between the channel of the device body 1 and the diversion pipe 2 when the diversion pipe 2 rotates, preventing gas leakage from weakening the training effect. The design of the folded structure can meet the rotation requirements of the diversion pipe 2 within a large angle range, while ensuring the sealing of the entire gas path, thereby maintaining a stable airflow pressure.
[0037] In one embodiment, such as Figures 2-3 As shown, a baffle 231 is fixed on the inner wall of the shunt tube 2 to limit the position of the float 23 relative to the shunt tube 2. The baffle 231 is used to prevent the float 23 from being blown out of the shunt tube 2 when the airflow changes suddenly or the patient's breathing is unstable. At the same time, it can stabilize the initial position of the float 23 under low flow conditions, ensuring the repeatability of the training process and the accuracy of the measurement.
[0038] In one embodiment, such as Figures 2-3 As shown, the float 23 can move 80mm to 120mm relative to the shunt tube 2, which makes it easier for the patient to judge the exhalation effect. It can also maintain a stable fit between the float 23 and the inner wall of the shunt tube 2 under the maximum displacement, preventing the float 23 from getting stuck or falling off.
[0039] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
