Of course, the present invention is not limited thereto, and a concave portion recessed toward the center of the mounting guide sleeve 114 may be provided on the mounting guide sleeve 114 of the lower housing 112 and a corresponding convex portion may be provided on the hollow connection tube 122 of the stethoscope head 120, whereby the stethoscope head 120 is restricted from rotating relative to the lower housing 112 by the convex portion on the hollow connection tube 122 of the stethoscope head 120 and the corresponding concave portion on the hollow connection tube 122 being engaged with each other.
In the in-service use process, in order to avoid the mutual infection between the patients, can also be provided with the disposable stethoscope head protecting film of detachable on stethoscope head main part 121, when changing the patient, need not to change the stethoscope, directly change the protecting film can.
In addition, the stethoscope head 120 can also collect electrocardiosignals through the top surface of the stethoscope head body 121. Meanwhile, an electrode (not shown) is disposed outside the lower housing 112, and is configured to collect an electrocardiographic signal and transmit the collected electrocardiographic signal to an electrocardiographic processing circuit of the electrocardiograph module 3, which will be described later. According to the embodiment of the present invention, the electrodes and the stethoscope head 120 are used together to collect the electrocardiographic signals.
As shown in fig. 2, a battery 150 is also fixedly mounted inside the lower case 112. The battery 150 is electrically connected to the main circuit board 130 to supply power to the auscultation portion of the electronic stethoscope when the auscultation portion is not connected to a power source.
The functions performed by the electronic stethoscope will be described in detail with reference to fig. 1, 4 to 7. As shown in fig. 1, the electronic stethoscope includes a microprocessor 1, and an auscultation module 2, an electrocardiograph module 3, a blood oxygen module 4, a bluetooth module 5, a data storage module 6, a sound prompt module 7, a display module 8, a power module 11, a key module 13, and the like electrically connected to the microprocessor 1.

[ auscultation module ]
As shown in fig. 1, 4 and 5, the auscultation module 2 includes an auscultation head 120, a sound sensor 141 on the second circuit board 140, and a circuit module 205 disposed on the main circuit board 130. The circuit module 205 comprises a driving circuit 205-1, a heart sound filtering and amplifying circuit 205-2, a lung sound filtering and amplifying circuit 205-3, a channel control circuit 205-4 and an audio conversion circuit 205-5.
The driving circuit 205-1 transmits the amplified electrical signal to the heart sound filtering and amplifying circuit 205-2 and/or the lung sound filtering and amplifying circuit 205-3. The channel control circuit 205-4 is used for controlling the on and off of the heart sound filtering and amplifying circuit 205-2 and the lung sound filtering and amplifying circuit 205-3. Specifically, as shown in fig. 5, the channel control circuit 205-4 adopts a four-out-of-one analog control switch for control, and after receiving the selection instruction from the key module 13, the microprocessor 1 controls the conduction of the cardiopulmonary sound channel by controlling a0 and a1, so that the heart sound mode 00: Y0A and Y0B are on, i.e., the heart sound channel is on, and the lung sound mode 01: Y1A and Y1B are on, i.e., the lung sound channel is on, and the cardiopulmonary sound mode 11: Y3A and Y3B are conducted, namely, the heart and lung sound channels are conducted simultaneously. The audio conversion circuit 205-5 converts the filtered and amplified electrical signal into an audio signal. Because the electronic stethoscope according to the utility model adopts the above-mentioned channel control circuit, therefore the user personnel can select any one of heart sound mode, lung sound mode or cardiopulmonary sound mode based on actual need.
Thus, the sound sensor 141 collects sound signals of heart sounds and/or lung sounds from the body of the patient through the stethoscope head 120, and transmits the sound signals to the circuit module 205 after converting the sound signals into electrical signals. Then, the heart sound filtering and amplifying circuit 205-2 and the lung sound filtering and amplifying circuit 205-3 of the circuit module 205 respectively perform filtering processing and amplifying processing on the heart sound and/or the lung sound signal, so as to improve the quality of the sound signal. Subsequently, the audio conversion circuit 205-5 converts the processed electric signal into an audio signal and sends the audio signal to the microprocessor 1. The microprocessor 1 then transmits the audio signal to the bluetooth module 5, and the bluetooth module 5 transmits the audio signal to the headset 12.
