Domestic and medical two-purpose sound recording and fetal heart sound listening stethoscope

Abstract

The invention relates to a domestic and medical two-purpose sound recording and fetal heart sound listening stethoscope, and belongs to the field of medical apparatuses. A stethoscope head (1), a sound conduction tube, a three-way tube and a listening tube protecting port are mutually connected, so that a pipeline stethoscope is constituted; a microphone, an amplifier (2), a recording-playing module (3), a transmission module (4), a power supply and the like are arranged in the stethoscope head, so that an electronic stethoscope, which is capable of recording and playing sound, is formed to listen two different stethoscopic sound effects. People can identify sounds from left side and right side through two ears, but the known stethoscopes are operated in a mode of communicating left and right ears, and subsequently, a listening habit is changed and a hearing threshold is narrowed; with the application of the stethoscope which adopts a novel dual-sound-track circuit, the listening habit is recovered and the hearing threshold is widened, so as to bring about benefits for doctors in auscultation. In addition, known fetal heart rate instruments cannot output original heartbeat sound, while by virtue of the novel stethoscope, actual fetal heartbeat sound can be listened, and meanwhile, the sound can be recorded or played; and when the sound is recorded, a voice catalog can be additionally annotated by virtue of the microphone, so that functions of searching and tracing an electronic medical record can be developed. Moreover, a carotid artery plaque detection method is more convenient and rapider than the known stethoscopes.

Description

technical field [0001] The invention relates to a dual-purpose recordable stethoscope for family medicine and a fetal heart sound stethoscope, which belong to the field of medical equipment, and specifically relates to a stethoscope for recording and playback of single or dual channels, a stethoscope for recording and playback of fetal heart sounds and a purely electronic stethoscope that can be recorded and played back. The device also relates to the application of the wireless transmitting and receiving device. Background technique [0002] Since the patent No. 2014 2 0724643.6 "Medical Electronic Stethoscope and Lifesaving Pager" stated that the electronic stethoscope cannot generate an electronic medical record to record the course of the disease during auscultation, but in the circuit only because (MIC-1) It cannot be carried out synchronously with the recording, making the recording and production of electronic medical records difficult to implement, so the present inv...

Problems solved by technology

[0003] In addition, for the products of fetal heart rate monitors on the market (attached pictures 19 and 20), there are deficiencies in that the sound heard is not the real heartbeat sound of the fetus and the lack of recording of the fetal heart rate change process

and Figure 17 The old-fashioned fetal heart sound receiver is shown, and a new fetal heart sound receiver is proposed due to the defect that pregnant women cannot answer it.
