Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a separate external tympanic stethoscope. Background Technology

[0002] Currently, commonly used medical stethoscopes employ an in-ear design, working by transmitting sound through a closed cavity at close range. This traditional stethoscope presents several problems in practical use:

[0003] 1. When working in the outpatient department, medical staff wear these earrings for extended periods, which can cause pain and discomfort inside the ear and cause great inconvenience to the users.

[0004] 2. The weight of the stethoscope is mainly attached to both sides of the ears, which increases the load on the cervical spine and can easily lead to cervical fatigue. Long-term use may have adverse effects on the health of medical staff. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems by providing a separate external tympanic stethoscope to address the issues of discomfort and increased cervical spine load associated with existing stethoscopes.

[0018] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0019] Working principle of the invention: This split external earphone stethoscope achieves efficient acquisition, processing and transmission of sound signals through a split design. Its core technology revolves around the collaborative work of the stethoscope 100 and the external earphone 200, with each component connected by specific logic to form a complete sound transmission link.

[0020] The stethoscope 100 comprises a handle 101, a connecting rod 102, and a stethoscope head 103, forming a stable operating unit. The stethoscope head 103 is the core functional area, integrating a controller 104, a stethoscope power supply 105, and a detection layer 110. The controller 104, as the signal processing center, includes a signal generator 106, a data storage unit 107, a real-time data processing module 108, and a sound signal analysis and conversion chip 109, forming a complete logical unit of "acquisition-processing-conversion." The external earphone 200 connects the first earphone head 201 and the second earphone head 202 via an ear clip 203. Its external design avoids the pressure on the ear canal typical of stethoscopes. Its core components, the signal receiver 204 and the signal conversion amplifier 205, ensure accurate sound signal reproduction.

[0021] When the detection layer 110 contacts the patient's body surface, the built-in sound signal acquisition chip 111 immediately initiates sound-to-electric conversion, converting the mechanical vibration sound waves generated by organs such as the heart and lungs into electrical signals. This electrical signal is transmitted to the controller 104 via wires. First, the real-time data processing module 108 performs primary filtering, and its integrated signal preamplifier 119 amplifies the weak signal by 10-20 times. The real-time data receiver 117 synchronously captures the dynamic signal, which is then formatted by the signal converter 118 and transmitted to the sound processing module 116. This module uses an adaptive noise reduction algorithm to eliminate environmental noise, and then the sound signal parsing and conversion chip 109 converts the processed electrical signal into a transmittable digital signal. The entire process delay is controlled within 50ms to ensure real-time sound transmission.

[0022] The processed digital signal is processed synchronously in two paths: one path is stored in a data memory 107, whose integrated emergency power supply 115 can guarantee offline storage for ≥7 days; the other path is transmitted via a signal transmitter 112 in the 2.4GHz wireless band, with a transmission distance of up to 10 meters. The data memory 107 supports cyclic overwrite storage, automatically retaining key data from the most recent 7 days when storage space is insufficient. The stethoscope power supply 105 supplies power to the above components, and the backup power supply 113 in the connecting rod 102 can automatically switch when the main power supply power is below 10%, ensuring continuous operation.

[0023] After the signal receiver 204 of the external earphone 200 captures the wireless signal, it transmits it to the signal conversion amplifier 205. This component restores the digital signal to an analog electrical signal and automatically adjusts the gain by 1-3 times according to the ambient noise. The processed electrical signal drives the earphone's sound unit. The first earphone head 201 and the second earphone head 202, fixed by the ear clip 203, directly contact the eardrum, realizing bone conduction of sound transmission, which reduces sound attenuation by 30% compared to the traditional air conduction method. The power cable 207 inside the ear clip 203 connects to the earphone power supply 206. The charging port 208 supports 5V / 1A fast charging, and can work continuously for 8 hours on a full charge.

[0024] The stethoscope head 103's wireless charging layer 114 supports Qi standard wireless charging and is compatible with mainstream medical device charging docks. The medical-grade biocompatible coating on the surface of the detection layer 110 is ISO10993 certified and can withstand 75% alcohol disinfection, preventing cross-infection. The controller 104's signal generator 106 can periodically send self-test signals; when a component malfunctions, it will emit a prompt tone through the earpiece, ensuring device reliability.

[0025] Example 1 1. Sound Transmission Device: A high-sensitivity microphone is used as the sound collection component, and the sound signal is transmitted to the eardrum contact component through a sound guide tube. The sound guide tube is made of soft silicone material, which has good flexibility and comfort and can adapt to different users' ear shapes.

[0026] 2. Ear drum contact component: Designed as an external ear clip structure, the inner side of the ear clip uses a soft silicone pad, which makes good contact with the ear drum and can accurately transmit sound signals to the ear drum while avoiding stimulation of the inside of the ear canal.

[0027] 3. Support structure: It adopts a headband support structure. The headband is made of highly elastic material and can be adjusted according to the size of the head, so as to evenly distribute the weight of the stethoscope to the head and reduce the pressure on the ears and cervical spine.

[0028] 4. Sound processing module: Equipped with a digital signal processing chip, it amplifies and reduces noise in the collected sound signals to improve the auscultation effect.

[0029] Example 2 1. Sound Transmission Device: Utilizing a multi-microphone array as the sound collection component, the sound signals collected from multiple microphones are synthesized through signal processing algorithms, improving the sensitivity and accuracy of sound collection. The sound guide tube features an adjustable length design, allowing adjustment according to the user's ear position to ensure optimal sound transmission.

[0030] 2. Eardrum contact component: Designed as an external ear hook structure, the ear hook is made of lightweight metal material with a soft silicone layer on the surface, which makes good contact with the eardrum and can accurately transmit sound signals to the eardrum while avoiding stimulation of the ear canal.

[0031] 3. Support Structure: A special suspension structure distributes the weight of the stethoscope across the neck and head via ear hooks and a neck support, reducing pressure on the ears and cervical spine. The neck support features an adjustable angle design, allowing it to be adjusted according to the user's head posture to ensure stability when worn.

[0032] 4. Sound Processing Module: Equipped with an advanced sound processing system, including digital signal processing chips, filters, and amplifiers, to perform multi-level processing on the collected sound signals, further improving the auscultation effect.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
