Description

Technical Field

[0001] This utility model relates to the field of respiratory monitoring technology, and in particular to a device for monitoring abdominal breathing movements. Background Technology

[0002] Abdominal breathing monitoring devices are crucial tools in respiratory rehabilitation, guiding patients to master correct breathing patterns. By tracking real-time changes in abdominal movement, they help patients correct thoracic breathing and improve diaphragmatic mobility. Traditional devices typically use an elastic sensing belt around the patient's abdomen, with built-in pressure or deformation sensors capturing abdominal wall movement data during the respiratory cycle. When abnormal respiratory rate, insufficient depth, or compensatory chest wall movement is detected, a wearable voice module plays prompts or instructions to remind the patient to adjust their breathing rhythm. This design is practically valuable in pulmonary function rehabilitation training and postoperative respiratory recovery, especially for patients with chronic obstructive pulmonary disease (COPD), providing intuitive visual feedback on breathing patterns and aiding in the reconstruction of physiological breathing mechanisms. However, traditional voice interaction modes suffer from environmental adaptability limitations in clinical applications. In group treatment settings, multiple devices simultaneously issuing voice prompts can cause sound mixing, reducing individual patients' attention and potentially leading to noise pollution in the ward, affecting the rest of other patients. Furthermore, the signal processing delay from data analysis to broadcasting of voice commands can lead to a misalignment between the breathing adjustment instructions and the patient's actual breathing phase, especially during rapid breathing mode switching, where delayed feedback may mislead the patient into forming an incorrect rhythm. Therefore, the field of respiratory monitoring technology needs to develop a diaphragmatic breathing movement monitoring device that is suitable for group therapy and can reduce feedback delay. Utility Model Content

[0003] In view of the above-mentioned prior art, the present invention provides an abdominal breathing movement monitoring device, which mainly solves the technical problem of how to improve the applicability of group therapy and reduce feedback delay.

[0004] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows: An abdominal breathing movement monitoring device includes a breathing sensor and a connecting belt. The breathing sensor and the connecting belt are connected. An indicator light and a voice announcer are provided on one side of the breathing sensor. Tactile feedback modules are symmetrically arranged on both sides of the connecting belt. Each tactile feedback module includes an electrical connection wire, an electromagnet, a magnetic sheet, and a buffer layer. The buffer layer is located on the inner side of the connecting belt, and the electromagnet is located on the outer side of the connecting belt. The magnetic sheet is fixedly connected to the buffer layer. The electromagnets on the two tactile feedback modules are respectively electrically connected to the breathing sensor through corresponding electrical connection wires.

[0005] Preferably, the electromagnet and the side of the magnet that are close to each other are provided with the same magnetic poles.

[0006] Preferably, the breathing sensor signal is connected to a Bluetooth transmitter, and the Bluetooth transmitter signal is connected to a controller.

[0007] Preferably, the magnet sheet is wrapped with a rubber layer, and the magnet sheet is fixedly connected to the buffer layer through the rubber layer.

[0008] Preferably, the connecting belt is made of an elastic material and is detachably connected to the breathing sensor.

[0009] Preferably, the connection point between the connecting belt and the breathing sensor is provided with a connecting slot and a connecting block, the connecting slot being fixedly connected to the connecting belt, and the connecting block being fixedly connected to the breathing sensor.

[0010] Preferably, an electrical connection hole is provided inside the connecting slot, and electrical connection posts that mate with the electrical connection hole are provided on both sides of the connecting block. The electrical connection hole is electrically connected to the magnet piece through the electrical connection wire.

[0011] Preferably, the electrical connection post is connected to the breathing sensor via a spring.

[0012] Preferably, the breathing sensor is equipped with a battery, and the bottom of the breathing sensor is provided with a signal connection hole and a charging hole. The breathing sensor is detachably connected to the Bluetooth transmitter through the signal connection hole.

[0013] Preferably, the electrical connection wires are arranged in a wavy pattern on the inside of the connecting belt.

[0014] The beneficial effects of this utility model are as follows: This application sets up a tactile feedback module and electrically connects the magnet in the tactile feedback module to the breathing sensor, so that the breathing sensor can control the electromagnet by monitoring the patient's breathing. When the patient's breathing rhythm is problematic, the electromagnet can control the magnet to generate pressure on the patient's waist and abdomen, prompting the patient to adjust their breathing rhythm.

[0015] Meanwhile, this application has two tactile feedback modules symmetrically set on both sides of the waist belt. When the patient's breathing rate is too high or too shallow, the tactile feedback module on one side is activated, and when the patient's breathing rate is too low or too deep, the tactile feedback module on the other side is activated. Through the two tactile feedback modules, the patient can be effectively reminded how to adjust their breathing rhythm without using voice.

[0016] This application uses a respiratory sensor to control the energization and de-energization of a control electromagnet, simulating the standard rhythm of breathing to perform alternating compression and retraction movements on the patient's lower back and abdomen. Compared to voice prompts, this provides faster and more timely feedback, reducing lag. If the patient's continuous adjustments fail to restore a normal breathing rhythm through the tactile feedback module, the respiratory sensor detects that the tactile feedback module's operation for a certain period has still not improved the patient's breathing rhythm. In this case, it activates the voice announcer and a raised light to guide the patient, their family, or a physician to assist in adjustments, thus improving reliability.

[0017] In summary, by incorporating a tactile feedback module, this application can guide patients to adjust their breathing rhythm in most cases without needing to activate a voice player, thereby improving the applicability of group therapy and reducing feedback delay.

[0021] Example 1 See attached document Figure 1-4This application provides an abdominal breathing movement monitoring device, including a breathing sensor 1 and a connecting belt 2. The breathing sensor 1 and the connecting belt 2 are connected. An indicator light 101 and a voice broadcaster 102 are provided on one side of the breathing sensor 1. Tactile feedback modules 201 are symmetrically arranged on both sides of the connecting belt 2. The tactile feedback module 201 includes an electrical connection line 202, an electromagnet 203, a magnetic piece 204, and a buffer layer 205. The buffer layer 205 is disposed on the inner side of the connecting belt 2, the electromagnet 203 is disposed on the outer side of the connecting belt 2, and the magnetic piece 204 is fixedly connected to the buffer layer 205. The electromagnets 203 on the two tactile feedback modules 201 are respectively electrically connected to the breathing sensor 1 through the corresponding electrical connection line 202. This device incorporates a tactile feedback module 201, with a magnet 204 within the module electrically connected to a breathing sensor 1. This allows the breathing sensor 1 to monitor the patient's breathing and control an electromagnet 203. When the patient's breathing rhythm is abnormal, the electromagnet 203 controls the magnet 204 to apply pressure to the patient's abdomen and lower back, prompting the patient to adjust their breathing rhythm. Simultaneously, two tactile feedback modules 201 are symmetrically positioned on either side of the waist belt. When the patient's breathing rate is too high or shallow, one module activates; when the breathing rate is too low or deep, the other module activates. These two modules effectively remind the patient how to adjust their breathing rhythm without requiring voice prompts. By controlling the energization and de-energization of the electromagnet 203 via the breathing sensor 1, the device simulates a standard breathing rhythm, applying alternating pressure and retraction to the patient's abdomen and lower back. This feedback is faster and more timely than voice prompts, reducing latency. When the patient's breathing rhythm cannot be restored to normal through tactile feedback module 201 despite continuous adjustments, the breathing sensor 1 detects that the tactile feedback module 201 has failed to improve the patient's breathing rhythm after a certain period of operation. It then controls the voice announcer 102 and the indicator light to activate, guiding the patient, their family, or a physician to assist in adjustments, thus improving reliability. In summary, by incorporating the tactile feedback module 201, this device can guide the patient to adjust their breathing rhythm in most cases without activating the voice player, improving the applicability of group therapy and reducing feedback delay. In this embodiment, the breathing sensor 1 is a piezoelectric breathing sensor 1 of model HKH-11C. It should be understood that other breathing sensors 1 commonly used in the art can also be used.

[0022] Specifically, the electromagnet 203 and the magnet 204 are set to have the same magnetic poles on the side that are close to each other, so that when the electromagnet 203 is energized, it effectively pushes the magnet 204 away from and slightly compresses the patient's abdomen, and when the power is off, the magnet 204 retracts, effectively prompting the patient's breathing rhythm.

[0023] Specifically, the respiratory sensor 1 is connected to a Bluetooth transmitter 3, and the Bluetooth transmitter 3 is connected to a controller. This device, through the Bluetooth transmitter 3, can wirelessly transmit the signal from the respiratory sensor 1 to the controller for respiratory status analysis and receive feedback information processed by the controller to detect and prompt adjustments to the patient's breathing. Depending on the portability requirements of the site, the controller can be a computer or mobile phone equipped with a Bluetooth receiver module, or other electronic devices capable of signal processing. Furthermore, in this embodiment, the adjustment of the electromagnet 203, the voice announcer 102, and the indicator lights is controlled by an 8051 microcontroller. It should be understood that any other control module commonly used in the art can also be used to control and regulate the above functions.

[0024] This device can also be used with an oxygen saturation finger cot to monitor changes in oxygen levels during a patient's breathing process in real time, recording data and oxygen saturation values ​​for each training session. It can also generate real-time updated visual charts on the user interface of electronic devices such as mobile phones or computers. The controller controls the indicator light 101 and the voice announcer 102 to produce corresponding light flashing frequencies and alternating long and short prompts. Combined with pressure changes in the tactile feedback module 201, auditory, visual, and tactile feedback work together to guide the patient in adjusting their breathing. While guiding the patient to adjust their breathing, this device collects relevant data. After the patient's breathing adjustment is completed, a report is generated to help nurses and doctors assess the patient's optimal respiratory ratio.

[0025] Example 2 See attached document Figure 1-5 The difference between this embodiment and Embodiment 1 is that the magnet 204 is wrapped with a rubber layer 206, and the magnet 204 is fixedly connected to the buffer layer 205 through the rubber layer 206. By providing the rubber layer 206, this device can reduce the noise generated by friction and collision between the electromagnet 203 and the magnet 204. Simultaneously, the buffer layer 205, in conjunction with the buffer layer 205, improves the patient's wearing comfort. In this embodiment, the buffer layer 205 is made of cotton fabric.

[0026] Specifically, the connecting belt 2 is made of elastic material and is detachably connected to the breathing sensor 1. In this embodiment, the elastic material is a cotton-covered elastic cord structure, which can improve the patient's wearing comfort.

[0027] Specifically, the connection point between the connecting belt 2 and the breathing sensor 1 is provided with a connecting slot 207 and a connecting block 103. The connecting slot 207 is fixedly connected to the connecting belt 2, and the connecting block 103 is fixedly connected to the breathing sensor 1. This device, by providing the connecting block 103 and the connecting slot 207, makes it easier and faster to put on and take off the connecting belt 2.

[0028] Specifically, an electrical connection hole 208 is provided inside the connecting slot 207, and electrical connection posts 104 that mate with the electrical connection hole 208 are provided on both sides of the connecting block 103. The electrical connection hole 208 is electrically connected to the magnet 204 through the electrical connection line 202. This device, through the electrical connection hole 208 and the electrical connection posts 104, enables the respiratory sensor 1 to control the movement of the electromagnet 203 and the magnet 204 by power-off switching, thus providing feedback on the patient's respiratory rhythm.

[0029] Specifically, the electrical connection post 104 is connected to the breathing sensor 1 via a spring 105. By incorporating the spring 105, this device can prevent the electrical connection post 104 from getting stuck when the connecting block 103 is installed with the connecting slot 207.

[0030] Specifically, the breathing sensor 1 is equipped with a battery 106, and the bottom of the breathing sensor 1 is provided with a signal connection hole and a charging hole 209. The breathing sensor 1 is detachably connected to the Bluetooth transmitter 3 through the signal connection hole. The signal connection hole can be connected to the Bluetooth transmitter 3 via a signal cable, and can also be connected to the controller via the Bluetooth transmitter 3. The battery 106 can power the breathing sensor 1, the voice broadcaster 102, the indicator light 101, and the electromagnet 203.

[0031] Specifically, the electrical connection wire 202 is arranged in a wavy pattern on the inner side of the connecting belt 2, so that the electrical connection wire 202 will not be damaged when the connecting belt 2 is stretched or contracted.

[0032] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
