[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-3 The multifunctional stethoscope in this embodiment includes a stethoscope head 1, and a temperature adjustment mechanism is provided on one side of the stethoscope head 1.
[0029] In this embodiment, the temperature regulation mechanism includes a sound guide tube 2 fixedly installed on one side of the stethoscope head 1. The stethoscope head 1 is made of all copper, which helps to conduct sound effectively. A main sound tube 3 is fixedly installed on one side of the sound guide tube 2. Natural rubber is provided on the outside of the sound guide tube 2 and the main sound tube 3. A mounting base 4 is fixedly installed on the outside of the main sound tube 3. Mounting boxes 5 are fixedly installed on both the left and right sides of the mounting base 4. A heating wire 6 is fixedly installed inside the mounting box 5. The heating wire 6 is a copper-nickel alloy heating wire with good electrical and thermal conductivity, which allows it to quickly transfer heat during the heating process. Its resistivity is moderate, and it can generate enough heat even at a low voltage. A thermal pad 7 is fixedly installed on one side of the heating wire 6.
[0030] The heat-conducting pad 7 has a heating groove on one side. The stethoscope head 1 is fitted with the heat-conducting pad 7 through the heating groove, facilitating effective heating of the stethoscope head 1. The heat-conducting pad 7 is made of graphite, which helps the heat-conducting pad 7. The front of the main sound tube 3 is equipped with a sound processing device 8, which includes a sound acquisition unit, an amplifier, a recording module, a sound analysis and processing module, and a display screen. The amplifier in traditional stethoscopes is mainly designed based on acoustic principles. It concentrates and amplifies the sound through the special shape and material of the stethoscope head and the conduction effect of the stethoscope tube, allowing doctors to hear sound details more clearly. The amplifier is the Hanhong Electronics DS88B stethoscope. The sound analysis and processing module is mainly used to encode and decode sound signals, realize the compression and decompression of sound data, and reduce the space and bandwidth required for data storage and transmission. In the recording equipment, the audio codec can convert analog sound signals into digital signals for encoding and storage, and then decode them back into analog sound signals during playback.
[0031] An elastic frame 9 is fixedly installed at the output end of the sound processing device 8. The elastic frame 9 is made of polycarbonate, a high-performance engineering plastic with high strength and toughness. Its elastic modulus is moderate, which can achieve elastic deformation to a certain extent and can return to its original shape after deformation. A stethoscope 10 is fixedly installed on one side of the elastic frame 9. A sponge pad is provided on the inner side of the stethoscope 10, and the sponge pad is used as an ear cover. Traditional stethoscopes often use a bell-shaped stethoscope head, which is shaped like a bell jar. It is mainly used to listen to low-frequency sounds, such as the diastolic rumbling murmur of mitral stenosis. Its characteristics are that it can collect and amplify sounds from a specific direction and has high sensitivity to low-frequency sounds, but its ability to capture high-frequency sounds is relatively weak. When using it, the stethoscope head needs to be closely attached to the skin to obtain the best sound transmission effect.
[0032] In this embodiment, for the convenience of doctors to wear it comfortably, a tightening component is provided on the outside of the elastic frame 9, which can more effectively analyze and process the recorded sound signals in real time, extract key diagnostic data, and display it to the doctor through the display screen. The display screen can show heart rate and respiratory rate, and indicate atrial fibrillation and valvular murmurs. The tightening component includes a first tightening band 11 fixedly installed on the right side of the elastic frame 9.
[0033] The first tension band 11 has a limiting ring 12 fixedly installed on one side, and a limiting pin 13 is hinged to the inner side of the limiting ring 12. The second tension band 14, which is inserted into the limiting pin 13, is fixedly installed on the left side of the elastic frame 9. The second tension band 14 has several limiting grooves inside. The limiting pin 13 is inserted into the second tension band 14 through the limiting grooves, which helps to limit the insertion of the second tension band 14. The first tension band 11 and the second tension band 14 are made of polyester fiber, which has high strength and stability, is not easily deformed, and can maintain the shape and size of the tension band. It also has good wear resistance and can withstand frequent use and friction.
[0034] Specifically, the user does so through...
[0035] The working principle of the above embodiments is as follows:
[0036] This multifunctional stethoscope, when in use, first activates the heating wire 6, which heats the heating pad 7. Once the heating pad 7 is heated, the stethoscope head 1 can be inserted into the mounting box 5, so that the stethoscope head 1 is inserted into the heating pad 7. The heating pad 7 heats the stethoscope head 1, making it warm and comfortable. The stethoscope head 1 can then be placed on the patient's skin for auscultation, improving patient comfort and avoiding discomfort caused by cold skin. It also reduces resistance in younger patients, increasing the device's usability. In effect, when listening with the auscultation head 1, the sound can be transmitted through the sound guide tube 2 and then into the main sound tube 3. The main sound tube 3 then transmits the sound to the sound processing device 8. At this time, the sound acquisition device is used to capture the sound signal inside the patient's body, the amplifier is used to amplify the sound signal, the recording module is used to record the amplified sound signal, and the sound analysis and processing module is used to analyze and process the recorded sound signal in real time, extract key diagnostic data, and display it to the doctor through the display screen. The display screen can display heart rate, respiratory rate, and indicate atrial fibrillation and valvular murmurs, etc.
[0037] When the device needs to be stored, the sound guide tube 2 can be bent and aligned with the elastic frame 9. Then, the second tension band 14 can be pulled to wrap the elastic frame 9 and the sound guide tube 2. The first tension band 11 and the second tension band 14 can then be pulled up and tightened to store the device. The limiting pin 13 can then be inserted into the second tension band 14 to secure the device and facilitate convenient and effective storage. By integrating sound acquisition, amplification, recording, and analysis processing functions, the stethoscope achieves integration and intelligence, greatly improving the doctor's diagnostic efficiency. The built-in sound analysis and processing module can provide detailed diagnostic data in real time, helping doctors to more accurately judge the patient's condition and improve the quality of diagnosis. The simple display screen interface design allows doctors to intuitively view the diagnostic results and is easy to operate.
