Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a lung function breathing trainer. Background Technology

[0002] The lungs, as the core organ of the human respiratory system, play a vital role in inhaling oxygen and expelling carbon dioxide. After oxygen enters the body through the lungs, it combines with hemoglobin in the blood, providing the necessary energy support for the normal metabolism and physiological activities of various tissues and organs. Therefore, the size of the lungs and the normality of the respiratory rate play a crucial role in maintaining human health.

[0003] However, in certain situations, such as lung disease, prolonged bed rest, postoperative rehabilitation, or long-term reliance on mechanical ventilation, lung function may be impaired to varying degrees. This impairment leads to reduced lung volume, weakened respiratory muscles, and decreased respiratory efficiency, resulting in a series of problems such as decreased oxygen intake, increased respiratory rate, and difficulty breathing. These problems not only affect the patient's quality of life but may also delay the recovery process or even worsen the condition. Therefore, effective exercise and rehabilitation training targeting impaired lung function are particularly important.

[0004] Currently, common methods for improving lung function include pursed-lip breathing and resistance breathing exercises. Pursed-lip breathing increases respiratory resistance by controlling the degree of lip opening, thereby strengthening the respiratory muscles and improving their endurance. Resistance breathing exercises, on the other hand, increase resistance during breathing to enhance the contractile ability of the respiratory muscles. While these methods are simple and easy to perform, they have some limitations in practical application.

[0005] Most existing breathing training devices are bulky and complex, making them inconvenient to carry and use, and failing to meet patients' needs for exercise anytime, anywhere. Furthermore, some simple alternatives, such as blowing up balloons, while easy to operate, offer only a single intensity level, making it impossible to adjust the exercise intensity according to the patient's recovery progress. Additionally, balloons are prone to breakage, posing certain safety hazards. Moreover, these methods do not provide users with direct feedback on the degree and effectiveness of their exercise, making it difficult for patients to accurately assess their recovery progress.

[0006] While patients can perform pursed-lip breathing anytime and anywhere, the lack of a reminder mechanism makes it easy for them to forget to practice, making it difficult to ensure the continuity and regularity of training. Furthermore, although the degree of lip opening during pursed-lip breathing can theoretically be adjusted, in practice, due to limitations in lip comfort, patients often find it difficult to precisely control breathing resistance, thus affecting the training effect. Utility Model Content

[0007] The present invention aims to provide a lung function breathing trainer to solve the problems of existing training equipment being bulky and difficult to carry, having limited functions, and lacking personalization and feedback mechanisms.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a lung function breathing trainer, comprising a cylindrical body with an open bottom, a trachea fixedly connected to the top of the cylindrical body, a movable groove formed at the top of the inner wall of the cylindrical body, the trachea communicating with the interior of the movable groove, two vertical sliding rods fixedly connected within the movable groove, a slider slidably connected to the movable groove, the two sliding rods passing through the slider, several air outlets formed on the side wall of the cylindrical body, a rotating groove formed at the top of the side wall of the cylindrical body, a rotating cylinder with an open top fitted around the cylindrical body, a connecting block fixedly connected to the inner side of the top of the rotating cylinder and cooperating with the rotating groove, several movable grooves formed on the side wall of the rotating cylinder, the air outlets being fully exposed at the movable grooves, and the... The rotating drum can completely block the air outlet during rotation. A knob is rotatably connected to the bottom of the drum, and a connecting column is fixedly connected to the top. The connecting column is connected to the inside of the drum body. A gear groove is opened inside the drum, and teeth are fixedly connected to the side wall of the gear. Gear 1 is fixedly connected to the connecting column. Gear 1 is located inside the outlet groove. Gear 1 meshes with gear 2. Gear 2 meshes with the teeth of the gear groove. A thread is provided at the top of the side wall of the connecting column. A pressing block is connected to the external thread of the connecting column. The pressing block has a through hole that cooperates with two sliding rods. The two sliding rods pass through the through hole. A compression spring is fixedly connected between the pressing block and the sliding block. A control device is installed inside the drum body.

[0009] Preferably, the control device includes a battery, a switch, a position sensor, a photosensitive sensor, a buzzer, a Bluetooth module, and a controller. The position sensor is located at the knob, and the photosensitive sensor is located in the movable slot.

[0010] Preferably, the outer wall of the knob is provided with anti-slip teeth.

[0011] Preferably, a limit block is provided at the top of the connecting column.

[0012] Preferably, a mask is connected to the free end of the trachea.

[0013] The principle and beneficial effects of this technical solution:

[0014] This device achieves a similar exercise effect to pursed-lip breathing by adjusting the size of the air outlet. In traditional pursed-lip breathing, patients increase respiratory resistance by changing the degree of lip opening, thereby exercising the strength and endurance of the respiratory muscles. The core structure of this device includes a cylindrical body with an open bottom, connected to a trachea at the top. The other end of the trachea can be connected to a mask or mouthpiece for convenient use. Inside the cylinder are a slider and a compression spring. The slider moves along a sliding rod under the action of airflow, while the compression spring provides resistance to the slider. When the patient blows air into the device through the trachea, the airflow pushes the slider, and the pressure exerted by the compression spring on the slider is converted into respiratory resistance, thus achieving the function of "resistance breathing exercise." By adjusting the resistance, patients can choose an appropriate exercise intensity according to their rehabilitation needs and physical condition.

[0015] By rotating the knob, patients can control the rotation of the cylinder, thereby changing the opening degree of the air outlet. The size of the air outlet directly affects the airflow velocity and resistance; therefore, by adjusting the opening degree of the air outlet, patients can simulate the effect of pursed-lip breathing while achieving stepless adjustment of breathing resistance. Furthermore, rotating the knob also moves the compression block up and down, further changing the pressure of the compression spring on the slider, thus achieving precise control of the intensity of the breathing exercise. This design not only improves the flexibility of the exercise but also provides patients with personalized rehabilitation plans.

[0016] The movement of the slider triggers the position sensor, indicating that the device has been used. If the sensor is not triggered within a certain period, the device will issue a reminder via a built-in buzzer or a mobile app to encourage the patient to perform regular training. Simultaneously, the position sensor at the knob monitors the opening degree of the air outlet in real time and calculates the corresponding resistance using an algorithm. Combining the patient's training duration and frequency, the controller analyzes the patient's training progress and transmits the data to the mobile app via Bluetooth. The app provides personalized training suggestions based on the patient's recovery progress, reminding the patient to adjust the training intensity as needed to maximize training effectiveness.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0021] Example:

[0022] like Figures 1-2 The illustrated pulmonary function breathing trainer includes a cylindrical body with an open bottom. A trachea is fixedly connected to the top of the cylindrical body, and the other end of the trachea can be connected to a mask or mouthpiece for patient use. A movable groove is formed at the top of the inner wall of the cylindrical body, and two vertical sliding rods are fixedly connected within the groove. A slider is slidably connected to each sliding rod. Several air outlets are formed on the side wall of the cylindrical body, and a rotating groove is formed at the top of the side wall. An open-topped rotating cylinder is fitted over the cylindrical body, and a connecting block that mates with the rotating groove is fixedly connected to the inner side of the top of the rotating cylinder. Several movable grooves are formed on the side wall of the rotating cylinder, allowing the air outlets to be fully exposed at the movable grooves, while the rotating cylinder can completely cover the air outlets during rotation. A knob is rotatably connected to the bottom of the rotating cylinder, and a connecting post is fixedly connected to the top of the knob, connecting to the interior of the cylindrical body. A gear groove is formed inside the rotating cylinder, and teeth are fixedly connected to the side wall of the gear groove. A gear one is fixedly connected to the connecting post, and gear one is located inside the gear groove. Gear one meshes with gear two, which meshes with the teeth of the gear groove. The top of the side wall of the connecting column is threaded, and a pressing block is connected to the external thread of the connecting column. The pressing block has through holes that mate with two sliding rods. The two sliding rods pass through the through holes, and a compression spring is fixedly connected between the pressing block and the sliding block. A control device is also installed inside the cylinder.

[0023] The control unit includes a battery, switch, position sensor, photosensor, buzzer, Bluetooth module, and controller. The position sensor is located at the knob; its position allows the algorithm to calculate the opening size of the compression block and air outlet, thus determining the current training intensity. The photosensor is located in the movable slot; its movement detects the slider movement, indicating that the patient is training. When there has been no training for an extended period, or when the training duration is sufficient, the buzzer serves as a reminder. The Bluetooth module connects to a mobile phone, and the corresponding app can provide reminders to the patient to increase the training intensity, start or stop the training, etc.

[0024] The knob's outer wall is equipped with anti-slip teeth to increase friction during operation and prevent slippage. A limit block is located at the top of the connecting column to prevent the compression block from detaching during movement. A mask is attached to the free end of the trachea for patient use.

[0025] To ensure that the device does not rotate on its own under natural conditions, there is resistance between several gears, knobs, connecting columns, rotating drums, and pressing blocks, or a pin is installed at the knob position to control the knob from rotating.

[0026] The specific implementation process is as follows:

[0027] The patient inhales through their nose and blows air into the device through their mouth via the trachea, causing the slider to move and the air to enter the device and exit through the outlet. Turning a knob rotates the rotating cylinder, blocking the outlet and changing its size to simulate pursed-lip breathing for training. Simultaneously, moving the knob moves the compression block up and down, changing the pressure of the spring on the slider and altering the difficulty of blowing air into the slider, also providing breathing training.

[0028] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions or characteristics are not described in detail here. For those skilled in the art, various modifications and improvements can be made without departing from the technical solution of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
