Embodiment Construction

[0013] exist figure 1 The middle stethoscope probe [1] is composed of a pickup, a parabolic reflex arc, an amplifier, an A / D analog-to-digital converter, and a Gaussian frequency shift filter. Stethoscope earplug [2] is made up of receiver, decoder, D / A digital-to-analog converter, amplifier and sound generator etc. The shape of earplug [2] can be made into circumauricular type, sticking ear type, earplug type and ear canal type etc., selects for the doctor of different habits. The paraboloid in the stethoscope probe [1] receives the sound wave, and it is completely reflected to the pickup by the reflection arc, and converted into an electrical signal, and then uses frequency modulation (FM), amplitude modulation (AM), WIFI, Bluetooth and Gaussian frequency shift keying (GFSK) And other technologies, the electrical signal is modulated and then emitted. Built-in stethoscope earplugs [2] with functions of receiving, decoding, and amplifying. After signal processing, it is conv...

Abstract

The invention discloses a multi-user electronic stethoscope capable of focusing an acoustic wave through a parabolic reflex arc. A parabolic reflex arc, an amplifier and an emitter are arranged in a stethoscope probe; a plurality of earplugs all are provided with receivers; and by adopting the technologies, such as frequency and amplitude modulation, WIFI, Bluetooth and Gaussian frequency-shift keying, the aim that auscultation information can be transmitted to a plurality of auscultation ear pieces by an auscultation probe in a wired or wireless manner and one acoustic source can be auscultated by multiple users at the same time is achieved. The original sound is strengthened through parabolic reflective focusing, and distortion is reduced. The earplugs are adopted for auscultation, so that discomfort of oppressing an ear canal is avoided; and auscultation can be carried out by adopting a unilateral ear, so that language communication is not affected. The confusion of a clinical doctor during teaching, ward-round and consultation is avoided, a plurality of users can listen at the same time, the volume is adjustable, and meanwhile, language communication can be carried out. A novel teaching aid is provided for cultivating medical students; and a more effective diagnostic tool is provided for doctors.

Description

Technical field: [0001] The invention is a novel electronic stethoscope composed of a stethoscope probe with a parabolic reflection arc focused sound wave and a plurality of earplugs. It is a tool for doctors to make differential diagnosis of physiological or pathological conditions on the sounds produced by the heart, breathing, and gastrointestinal tract of humans or animals to determine the condition. It is especially suitable for teaching in medical colleges and clinical ward rounds, consultation and teaching in hospitals. Background technique: [0002] At present, the stethoscope used by doctors has always been the traditional type that conducts sound through the air in the rubber tube, and it has not changed much for more than one hundred years. The earpieces of the stethoscope are tightly plugged into the doctor's ear canal, which will inevitably cause discomfort and pain, which is an unavoidable confusion for clinicians using stethoscopes. Only the doctor can auscu...
