[0020] Reference Figures 1 to 4 The utility model provides a multifunctional medical ultrasound probe, which can solve the defect of the existing medical ultrasound probe having a single function.

[0021] The present invention provides a multifunctional medical ultrasound probe, comprising: a medical probe body 10, one end of which is connected to a medical probe cable 20, and the other end of which is provided with a medical probe protective layer 30. The medical probe protective layer 30 is integrated with a piezoelectric film 40 and at least two temperature measurement units 50. The piezoelectric film 40 is located in the middle of the medical probe protective layer 30, and the at least two temperature measurement units 50 are respectively located at both ends of the piezoelectric film 40.

[0022] The medical probe body 10 is an existing product, as long as it can achieve the effects and functions of the present application;

[0023] The piezoelectric film 40 is used to collect sounds from organs such as the heart, lungs, and intestines, and the temperature measurement unit 50 is used to measure body temperature;

[0024] The ultrasonic frequency of a medical probe is generally 2MHz to 18MHz, and the frequency of heart and lung sounds is mostly above 1MHz. To improve the accuracy of signal acquisition, this application uses a filter to filter out high-frequency signals, and then collects and converts the electrical signals, and finally sends them to the CPU for processing. At the same time, to reduce the impact of the newly added piezoelectric film 40 and the ultrasonic signal collected, all processing circuits are placed behind the ultrasonic piezoelectric crystal;

[0025] In this application, the temperature measuring unit 50 is located at both ends of the piezoelectric film 40, that is, the temperature measuring unit is placed outside the sound wave collection area to reduce the influence of the temperature measuring unit 50 on the sound wave, and multi-point temperature measurement is set. All circuits are placed behind the piezoelectric crystal. For the working circuit diagram of the temperature measuring unit 50 in this application, please refer to Figure 3 .

[0026] The present invention provides a multifunctional medical ultrasound probe. One end of the medical probe body 10 is connected to a medical probe cable 20. The other end of the medical probe body 10 has a medical probe protective layer 30. The medical probe protective layer 30 is integrated with a piezoelectric film 40 and at least two temperature measurement units 50. The piezoelectric film 40 is located in the middle of the medical probe protective layer 30, and the at least two temperature measurement units 50 are located at both ends of the piezoelectric film 40. This application can add the functions of collecting piezoelectric film signals of heart and lung sounds and body surface temperature signals to the existing medical probe. Therefore, when measuring heart and lung sound and temperature, the multifunctional medical ultrasound probe of the present application can be used directly without the need for other equipment, greatly reducing hospital equipment costs and patient examination time. Therefore, the present invention solves the problem of the single function of medical ultrasound probes in the prior art, while reducing costs and improving work efficiency.

[0027] Reference Figure 2 Optionally, at least two temperature measuring units 50 are evenly arranged at both ends of the piezoelectric film 40 .

[0028] Among them, the role of uniform arrangement is to make the temperature measurement results stable.

[0029] See also Figure 2 Optionally, there are two temperature measuring units 50 , and the two temperature measuring units 50 are symmetrically arranged at both ends of the piezoelectric film 40 .

[0030] Among them, the temperature measurement area of ​​the two temperature measurement units 50 in this application is A.

[0031] Optionally, the temperature measuring unit 50 is a diode temperature sensor.

[0032] The temperature measuring unit 50 uses a diode temperature sensor that utilizes the PN junction temperature characteristics of the diode. Different temperatures result in different leakage currents, and thus the temperature can be measured. This is a contact temperature measurement method.

[0033] Combine Figure 3 To illustrate the temperature measurement principle of the temperature measurement unit 30 in this application, the voltage across the test diode is linearly related to body temperature. As the temperature changes, the current across the diode remains constant, while the voltage across the diode changes with the body temperature. In practice, the voltage change across the diode is monitored, and then further analog-to-digital conversion (analog-to-digital converter 14) is performed, and the result is sent to the processor 15 (CPU) for subsequent display, alarm, and other operations for the doctor's diagnosis.

[0034] Working principle (cardiopulmonary sound piezoelectric film signal acquisition, refer to Figure 4 );

[0035] The piezoelectric film used for cardiopulmonary sounds vibrates under the drive of the sound waves of cardiopulmonary sounds, redistributes the surface charge, and then generates electrical signals. Depending on the sound waves, the amplitude and period of the generated electrical signals are different. These electrical signals are filtered by a series of filters 11, converted by current-voltage converters 12, amplified by amplifiers 13, and converted by analog-to-digital converters 14, and sent to processors 15 for consultation and analysis using computer algorithms.
