[0004] For this reason, the prior art provides a teaching stethoscope for auscultation learning. For example, the Chinese invention patent with the publication number of CN117159018 A and the name of "Electronic Auscultation System and Electronic Auscultation Method" includes: a stethoscope head and multiple playback terminals; the stethoscope head includes: an acquisition terminal and a processing terminal; the acquisition terminal is used for acquiring audio signals; the processing terminal is communicatively connected with the acquisition terminal and is used for receiving the audio signals and processing the audio signals to generate high-frequency digital signals; the multiple playback terminals are respectively communicatively connected with the processing terminal and are used for receiving the high-frequency digital signals and performing reduction processing to generate target audio signals and playing the target audio signals.

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Please refer to Figures 1-4 , a new type of stethoscope for teaching, including an interaction part 1, a sound pickup part 2 and a conduction part 3. The interaction part 1 and the sound pickup part 2 are connected through the conduction part 3 to transmit power and data;

[0033] After the sound pickup part 2 picks up the sound, it is transmitted through the conduction part 3 and played on the interaction part 1;

[0034] The interaction unit 1 includes a controller 101. Teaching data such as different types of heart cases are stored inside the controller 101. A loudspeaker 104 is also provided on the side of the controller 101;

[0035] The sound pickup unit 2 includes an electronic sound pickup 201. A connection head 202 is fixedly connected to the top of the electronic sound pickup 201. An integrated circuit and a data transmission line are inside the connection head 202 to facilitate the plugging and unplugging of the conduction unit 3. The connection head 202 is connected to the conduction unit 3;

[0036] A vibration thin sheet 203 is fixedly connected to the bottom of the electronic sound pickup 201. The vibration thin sheet 203 is an ultra-thin metal diaphragm, which can effectively conduct the vibration of sound and conduct pressure. A component for sensing pressure is provided between the vibration thin sheet 203 and the electronic sound pickup 201.

[0037] Through the above technical solution, a component for sensing pressure is provided between the electronic sound pickup 201 and the vibration thin sheet 203. During simulated auscultation, the component for sensing pressure will transmit signals to the electronic sound pickup 201 according to the intensity and position of the pressure. Thus, the electronic sound pickup 201 selects corresponding audio to play according to the pressure angle and gravity. Different pressures and angles result in different played audio, achieving the effect of enhancing student interaction;

[0038] During normal auscultation, the interaction unit 1 does not transmit audio signals to the electronic sound pickup 201. Instead, the electronic sound pickup 201 directly picks up the cavity sound of the patient, then converts it into a digital signal and transmits it through the conduction unit 3, and then plays it out from the interaction unit 1 to achieve auscultation in the normal mode;

[0039] When there is no patient, teaching audio stored inside the interaction unit 1 is played to achieve the effect of simulated auscultation;

[0040] And during simulated auscultation, the component for sensing pressure can select different audio to play according to different pressure angles received. For example, during heart auscultation, if the component for sensing pressure is evenly stressed, the sound of the front heart is played. When the pressure on the left side increases, an audio with a heavier sound of the left atrium is selected for playback. On the right side, playback is carried out accordingly, thereby enhancing student interaction.

[0041] Specifically, the component for sensing pressure includes a main pressure sensor 2031 and a secondary pressure sensor 2032. The main pressure sensor 2031 is fixedly connected to the axis at the top of the vibration thin sheet 203;

[0042] The number of auxiliary pressure sensors 2032 is multiple, and the multiple auxiliary pressure sensors 2032 are annularly arrayed on the top of the vibrating sheet 203 with the main pressure sensor 2031 as the axis;

[0043] Both the main pressure sensor 2031 and the auxiliary pressure sensors 2032 are electrically connected to the conduction part 3 by signals.

[0044] Through the above technical solution, the main pressure sensor 2031 is set to determine the intensity of the central force, and the auxiliary pressure sensors 2032 are set to determine the tilting direction when tilted through the difference value, so as to determine the angle of the stethoscope and the pressing force, and then determine the played audio according to the pressure and the tilting angle.

[0045] Specifically, signal wires 2033 extend from all the auxiliary pressure sensors 2032. A pad 2034 is fixedly connected to the top of the main pressure sensor 2031. The signal wires 2033 are electrically connected to the pad 2034, and the pad 2034 is welded to the conduction part 3.

[0046] Through the above technical solution, all the auxiliary pressure sensors 2032 are individually encoded and then connected through the signal wires 2033. Thus, after the auxiliary pressure sensors 2032 are pressed, electronic data will be generated. The tilting direction and angle are determined according to the different differences of the electronic data, and then the data is transmitted to the inside of the electronic pickup 201 through the conduction part 3, and the electronic pickup 201 selects the audio to play according to the obtained data.

[0047] Specifically, the interaction part 1 includes a controller 101. A storage terminal, a collection terminal, a playback terminal, a battery part and a communication module are fixedly connected inside the controller 101. The storage terminal, the collection terminal and the communication module transmit data to each other. The playback terminal reads the data of the storage terminal, and the battery part supplies power to the storage terminal, the collection terminal, the playback terminal and the communication module.

[0048] Through the above technical solution, the storage terminal is used to store various cases, and a case library is established through the stored cases for convenient teaching use;

[0049] The collection terminal is used to collect the conditions of patients during auscultation activities, so as to expand the case library;

[0050] The case information obtained by the storage terminal and the collection terminal is classified and stored manually or by voice features, such as: classified by the type of disease and the difficulty of diagnosis, so as to facilitate students to select appropriate practice content according to their own learning progress and interests;

[0051] The playback terminal is used to play audio and video. During auscultation, it plays the sounds obtained during auscultation, stores the sounds of the audio, and displays them in the form of waveforms on the screen to facilitate students' understanding and note-taking.

[0052] The battery unit is used to supply power to the device. It is mainly a lithium battery and can be charged repeatedly.

[0053] The communication module includes, but is not limited to, a wired transmission module and a wireless transmission module, so that data can be stored or read from the controller 101 in a wired or wireless manner, facilitating teachers to expand the case library and students to export case information for learning.

[0054] Each case will record in detail the patient's basic information, medical history, physical examination results, heart sound waveforms, diagnosis results, and possible misdiagnosis situations, so that students can comprehensively understand the diagnosis process.

[0055] The specific implementation method is the same as the principle in the Chinese invention patent with the publication number: CN 117159018 A and the name "Electronic Auscultation System and Electronic Auscultation Method".

[0056] Specifically, the interaction part 1 also includes a data interface 102 arranged on the side of the controller 101. The data interface 102 is respectively connected to the storage terminal and the battery unit, and its method is like the charging interface of a mobile phone, which can both charge and transmit data.

[0057] The loudspeaker 104 is signal-connected to the playback terminal.

[0058] Through the above technical solution, the set data interface 102 is used for charging and data transmission, and the set loudspeaker 104 is used for playing audio to realize the design without a stethoscope head. Thus, during auscultation or simulated audio playback, the sound will be directly played through the loudspeaker 104 to avoid the sound attenuation and distortion of traditional stethoscopes and provide real and accurate heart sound transmission.

[0059] The loudspeaker 104 is built-in with a high-quality amplifier to enhance the heart sound output and improve the auscultation effect.

[0060] Specifically, a display screen 103 is installed on the top of the controller 101. The display screen 103 is connected to the acquisition terminal and the playback terminal.

[0061] Through the above technical solution, the set display screen 103 is used to display the high-definition heart beating waveform during auscultation and at the same time provide real-time heart sound analysis results.

[0062] Moreover, through audio analysis technology, it automatically identifies and displays each valve sound, breath sound, and special heart sounds, such as gallop rhythm, resonance, hyperresonance, etc., enabling students to learn better.

[0063] Specifically, the display screen 103 is an electronic touch screen.

[0064] Through the above technical solution, the display screen 103 is set as a touch screen, so that teachers and students can operate more conveniently, and intuitive functions such as observation, control, and adjustment can be realized through an intuitive UI interface.

[0065] During use, by arranging a component for sensing pressure between the electronic pickup 201 and the vibrating sheet 203, when performing simulated auscultation, the component for sensing pressure will transmit signals to the electronic pickup 201 according to the intensity and position of the pressure, so that the electronic pickup 201 can select corresponding audio for playback according to the pressure angle and gravity. Different pressures and angles result in different played audio, achieving the effect of enhancing student interaction;

[0066] By providing a loudspeaker 104 on the side of the controller 101, a design without a stethoscope head is realized. Thus, when performing auscultation or simulated audio playback, the sound will be directly played through the loudspeaker 104 to avoid sound attenuation and distortion of traditional stethoscopes and provide real and accurate heart sound transmission.

[0067] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
