Description

Integrated heart main and pulmonary valve stethoscope

Technical Field

The utility model relates to a stethoscope especially relates to an integral type heart aortic valve, pulmonary valve stethoscope.

Background

Auscultation refers to the examination of the self-generated sounds (usually heart sounds, breath sounds, etc.) in the human body by the ears or stethoscope, and the diagnosis of pathological changes in the relevant organs is based on the characteristics and changes of the sounds (such as the frequency, intensity, interval time, murmur, etc.). The stethoscope has certain amplification effect on the sound of heart activity, can block noise in the environment, has wide application range, and can be used for auscultation of heart, lung and abdomen and listening to the sound emitted by other parts of the body, such as blood vessel sound, subcutaneous emphysema sound, fasciculation sound, joint activity sound, fracture surface friction sound and the like. With the development of electronic technology, the stethoscope category is developed from acoustic stethoscopes to electronic stethoscopes. The electronic stethoscope amplifies the body sound by using an electronic technology, converts the collected sound into an electric signal and then amplifies and processes the electric signal, overcomes the defect of high noise of an acoustic stethoscope, overcomes the interference of subjective factors in the auscultation process, and provides objective data for the auscultation of the heart and the diagnosis of diseases.

In some cases, a physician needs to auscultate two parts of a patient, such as the heart aortic valve, the pulmonary valve, to obtain the patient's health status.

The existing electronic stethoscopes are all arranged at a single head, and only one position can listen to the other position after listening, so that the comparison of the intensities of sounds listened at the two positions depends on the memory of a doctor himself on the intensity of the sound at the previous position, and certain difficulty is brought to diagnosis. Furthermore, listening to one and then the other has the disadvantage that the sounds of both auscultations are not vibrations or sounds excited by the same heartbeat.

SUMMERY OF THE UTILITY MODEL

In view of the above problem, the present invention aims to provide an integrated heart main valve and pulmonary valve stethoscope, which can auscultate two parts of a patient at the same time, and emit auscultation sounds of the two parts at the same time, so as to provide a direct basis for a doctor to determine the health condition of the patient.

Detailed Description

The integrated heart main and pulmonary valve stethoscope according to the present invention will be described in detail with reference to the accompanying drawings.

The application discloses integral type heart aortic valve, pulmonary valve stethoscope, it includes: two electronic auscultation heads.

Each of the electronic heads includes a tubular body 10, and the lower end of the body 10 is covered with a membrane 11, serving as an auscultation membrane, to vibrate according to sound or vibration of a detection site. The upper end of the main body 10 is provided with a panel 12; the panel 12 is provided with a key 23, a loudspeaker 26, a touch screen 24 and a display unit 27; a circuit board is fixedly installed in the main body 10, and the circuit board comprises a control unit 20, a signal conditioning circuit 21a, an A/D21 b, a display driving circuit 27a and a touch screen driving circuit 24 a; the microphone 21 senses sound generated by the vibration of the membrane 11. The sound pickup 21 is connected to a signal conditioning circuit 21a, the output of the signal conditioning circuit 21a is connected to an a/D21 b, and the output of the a/D21 b is connected to the control unit 20, so that the control unit 20 receives the sound signal collected by the sound pickup 21. The control unit 10 drives the speaker 26 according to the intensity of the collected signal to radiate the sound collected at the position; the control unit 10 outputs the waveform of the collected signal and the frequency signal to the display unit 27 to provide visual information; the display unit may be an OLED screen; the touch screen 24 is connected to the control unit 10 via a touch screen driving circuit 24a to perform instruction input or patient information input to the control unit 10 through the touch screen 24; the touch screen 24 is stacked on the display unit 27, which is similar to the combination of the display screen and the touch screen of the common smart phone; the control unit 10 may be a single chip microcomputer.
