Description

Wireless electronic stethoscope

Technical Field

The invention belongs to an examination tool for medical profession, and relates to a wireless electronic stethoscope.

Background

For a long time, the stethoscope used by medical staff during auscultation examination in diagnosis and treatment activities is a tubular traditional stethoscope of a chest piece (an earphone), a sound transmission tube and earplugs, is convenient and easy to use clinically, but is easy to catch cold when the chest and the abdomen are exposed in cold winter; the use of the traditional stethoscope for a large number of continuous physical examinations can cause the skin of the external auditory meatus of medical staff to be extruded to cause pain and discomfort; especially, under the condition that the multi-layer protection isolation protective clothing is worn in an infectious disease area, the stethoscope can not be used for knowing the functional conditions of the internal organs of the patient, such as the heart, the lung and the abdomen, and the like, and a very simple and convenient disease observation means is inevitable.

Many companies at home and abroad are carrying out research and development and production of electronic stethoscopes, and the fields of various military intelligent electronic stethoscopes such as Sichuan olong medical equipment limited company, Jinnan olong bioengineering limited company, Shenshan Kedelion electronic limited company, Shenzhen Yun Zhi Lian technology limited company, American 3M, Feelix and Feelix Pro are emphasized, and the research and development of the electronic stethoscopes are mainly focused, and most of the electronic stethoscopes are similar to the traditional stethoscopes in structure, so that the sound size adjustment is realized, the sound is amplified by dozens of times without distortion, clutter is filtered, the effect is clearer, the skin of a patient is not required to be contacted during auscultation, or the patient avoids the cold feeling when an anti-freezing membrane is adopted, and the detection sensitivity is high, so that the subtle change sound of cardiopulmonary sound can; patient auscultation data storage, file building, intelligent analysis, printing, E-mail data transmission, remote online auscultation, expert collective consultation and other comprehensive information data management, digitalizes and visualizes the cardiopulmonary sounds of the patients, establishes an information database of the patients through online transmission, and calls the information database when needed; the auscultation head is soft, the ears are not damaged after long-time use, and the fatigue of the ears is reduced; low energy consumption design and manual replay adjustment. The Cai Sheng team develops an electronic stethoscope product and additionally performs related cardiopulmonary disease auxiliary diagnosis based on artificial intelligence, helps doctors to improve the diagnosis capability, and can be put to home like an electronic sphygmomanometer thermometer; the wireless electronic stethoscope gradually goes to the market and becomes an important intelligent medical product.

The electronic stethoscope with a tube or an earphone wire cannot be used under the condition that a patient infected area is worn with a plurality of layers of tight protective isolation clothes.

Disclosure of Invention

The invention aims to provide an electronic stethoscope for medical care personnel with wireless transmission and reception, which solves the problem that the traditional stethoscope cannot be used in a tightly protected infectious disease area; the pain and discomfort caused by the extrusion of the stethoscope head on the skin of the external auditory canal are avoided for a large number of medical staff for continuous physical examination; and digital storage, transmission, intelligent assistance and the like of auscultation audio.

The solution is as follows: wireless electronic stethoscope comprises bell-shaped chest piece and miniature wireless earphone, the circular vibrating diaphragm lock joint in bell-shaped chest piece bottom is inlayed in the horn mouth bottom that stainless steel or titanium alloy cast, the vibrating diaphragm upwards conducts received sound wave along the horn neck, the horn neck has the collection, the amplification effect, set up a miniature adapter in horn neck sound centralized position, convey received sound wave to horn neck outside treater and convert electronic signal into again, send to wireless receiving earphone through bluetooth, the treater can strain miscellaneous amplification, it is clear to guarantee that the earphone hears organs audio information such as patient's heart lung, can replay, the amplification reduces adjustably, the lithium cell is laid to horn neck outside treater offside, provide the power for the treater. There is charging socket the outside, switch, loudspeaker neck top adds there is the protecting cover, the centre is left the several and is led the sound hole, guarantee that sound directly spreads and not sheltered from the shielding, can the at utmost produce resonance, improve the auscultation effect, install the gliding gleitbretter that makes a round trip additional on the top cap, the card covers in the centre when not time spent and leads the sound hole, avoid polluting, slide to the edge during the use, expose and lead the sound hole, guarantee to pass the sound unblocked, accomplish the timely understanding of the functional aspect of auscultation to patient's internal organs.

The utility model has the advantages that the defect that medical staff in an infectious disease area can not use a stethoscope to know the functions of the heart, the lung and the abdomen of a patient under the multi-layer tight protection is overcome; the extrusion pain of the traditional stethoscope to the external auditory canal of medical staff during a large number of physical examinations is avoided; the auscultation information of the patient can be stored, replayed, amplified and reduced, and is transmitted remotely, the comparison before and after treatment is convenient, the auscultation information can also be used as personal data of the patient for filing and future reference, one person can share the auscultation information with other people, the disturbance to the patient is reduced, the auscultation effect is improved, and the auscultation information is a good teaching aid for clinical teaching and teaching; the cardiopulmonary audio of the patient is digitized, and the diagnosis is assisted by artificial intelligence, so that the diagnosis capability of a doctor can be improved. High sensitivity, low power consumption and long service life of the battery. The wireless electronic stethoscope becomes an important intelligent medical product.
