Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment and is a wearable expectoration aid designed for patients with respiratory diseases that is lightweight and easy to wear. The wearable expectoration aid can realize the integration of lung sound recognition and expectoration functions through a distributed electronic stethoscope and a vibrating percussion head integrated on the wearable aid, and is suitable for patients who require long-term expectoration management. Background Art

[0002] For patients with respiratory diseases, such as chronic obstructive pulmonary disease, regular expectoration is an important treatment method to relieve dyspnea. However, existing expectoration methods, such as manual percussion expectoration, vibrating expectoration machine expectoration, and vibrating expectoration vest expectoration, are inefficient and have a small scope of use, and still cannot completely replace manual expectoration care.

[0003] At the same time, existing sputum removal care equipment also lacks real-time monitoring capabilities for individual patients' lung conditions, and is unable to intelligently sense the lung status, provide feedback on the effectiveness of patients' sputum removal care, and adjust care strategies in a timely manner.

[0004] Therefore, in order to reduce the burden on medical staff and assist and replace nursing staff in completing expectoration care tasks, it is urgent to develop an integrated wearable expectoration aid that integrates lung sound recognition function and vibration expectoration function.

[0006] An integrated wearable expectoration aid based on lung sound recognition, characterized by comprising a distributed electronic stethoscope, an array of flexible and variable-rigidity electromagnetic percussion heads, a vest-type wearable backpack, and an aid hard backpack shell.

[0007] The distributed electronic stethoscope is used to collect the patient's lung sound signals, the flexible variable stiffness electromagnetic percussion head array is used to perform vibration expectoration operations at the corresponding position of the patient's back, the vest-type wearable backpack is used to be worn on the patient's upper body, and the auxiliary hard backpack shell is the movement reference of the percussion head array to ensure the percussion effect.

The flexible percussion heads are made of flexible materials and can adjust the rigidity according to the percussion requirements to maximize the treatment effect and reduce the patient's discomfort.

[0010] Preferably, the flexible percussion head can use highly elastic and wear-resistant materials, such as human silicone or special polymers, to further improve the expectoration effect and increase the life of the auxiliary device while ensuring the effect.

[0011] The distributed electronic stethoscopes are evenly distributed on the front, side and back of the auxiliary device, and can efficiently collect the patient's lung sound signals for judging the nursing effect.

[0012] The vest-type wearable backpack is designed to fit the shape of the patient's back and uses adjustable straps to accommodate patients of different body shapes. There is a support structure inside the backpack to ensure the precise positioning and stability of the percussion head, ensuring that the percussion head maintains good contact with the patient's back during the treatment process.

[0013] Preferably, for the supporting structure of the tapping head, highly elastic and wear-resistant materials, such as sponge or special polymers, are used. These materials not only provide the necessary mechanical support, but also ensure the comfort and safety of the tapping process.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention is described clearly and completely below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] The present invention provides a technical solution: an integrated wearable expectoration aid based on lung sound recognition, comprising 1- a hard backpack shell, 2- backpack shoulder straps, 3- a tapping head supporting sponge, 4- a flexible electromagnetic tapping unit with variable stiffness, 5- a backpack belt, 6- a front baffle of the aid, 7- a distributed electronic stethoscope, 8- an electromagnetic tapping unit supporting shell, 9- an electromagnetic tapping unit, 10- a flexible tapping head, 11- a tapping head mounting base plate, etc.

[0023] Installation and initialization: The assistive device needs to be initialized before use. Adjust the vest-type wearable backpack to the size suitable for the patient and fix it on the patient's back to ensure that the distributed electronic stethoscope has good contact with the skin. After the assistive device is started, a self-test is performed, including a test of the freedom of movement of the flexible variable stiffness electromagnetic percussion unit and a sensitivity test of the distributed electronic stethoscope to ensure that all components function properly.

[0024] When wearing the assistive device, the length of the shoulder straps and waist belt can be adjusted to accommodate patients of different body shapes.

[0025] Lung sound collection and data analysis: The distributed electronic stethoscope captures the patient's lung sound data in real time and sends it to the host computer. The data processing unit in the host computer uses a preset algorithm to analyze the received lung sound data, especially to identify specific lung sounds that indicate possible sputum retention.

[0026] Execution of expectoration care: After the host computer identifies the lung area that needs expectoration care, it will calculate and send detailed instructions to the flexible variable stiffness electromagnetic percussion head array. Each percussion unit adjusts its stiffness and percussion frequency according to the received instructions to optimize the treatment effect.

[0027] The flexible variable stiffness electromagnetic tapping unit consists of a flexible tapping head and an electromagnetic tapping unit. The basic principle of the electromagnetic tapping unit is similar to that of an electromagnet. It converts the electric field into a magnetic field through the internal electromagnetic coil, thereby driving the iron core in the middle of the electromagnetic tapping unit to perform reciprocating motion, simulating the tapping and patting back action of a nursing staff.

[0028] The flexible and variable-stiffness electromagnetic percussion head array dynamically adjusts the percussion sequence and strength based on the results of lung sound analysis, accurately treats areas with more sputum, monitors the treatment effect, and adjusts the percussion parameters when necessary.

[0029] Feedback and adjustment of expectoration effect: During the nursing process, the distributed electronic stethoscope continues to monitor the patient's lung sound changes, and the real-time data is fed back to the host computer. The host computer evaluates the treatment effect based on the latest lung sound data and can automatically adjust the percussion strategy to achieve the best treatment effect.

[0030] The solution proposed in the present invention accomplishes two specific tasks by designing an integrated wearable expectoration aid: first, it combines lung status perception with expectoration care to provide an integrated expectoration care aid, thereby improving the convenience of the expectoration care aid during use; second, a flexible percussion head with variable stiffness is designed, and different percussion stiffness can be set for different patient groups to achieve better expectoration care effects.
