Ultrasound therapy, as an important physical therapy method, plays a key role in clinical treatment. Ultrasound refers to mechanical vibration waves with a frequency above 20kHz (kilohertz), which cannot cause auditory response in normal people. Ultrasound therapy achieves the purpose of treating diseases by applying ultrasound to the human body. This study aims to evaluate the performance of ultrasound therapy equipment, explore its effects and existing problems in clinical applications, and propose corresponding solutions.
Theoretical basis and previous research results
The mechanism of action of ultrasound therapy mainly includes thermal effect, mechanical effect and cavitation. When ultrasound propagates in a medium, it produces a waveform with alternating density. The propagation speed of the sound wave is related to the characteristics of the medium, not the frequency of the sound wave. Ultrasound therapy has been widely used in the treatment of multiple systems such as the nervous system, heart and blood vessels, bones, muscles and connective tissues.
Previous studies have shown that the performance of ultrasound therapy equipment has an important impact on its treatment effect. For example, in a 1982 study, CJ Snow found that of the 26 ultrasound therapy devices used clinically in Manitoba and the Northwest Territories, Canada, only 19% of the devices met the Canadian government's standards in terms of power level. This study revealed the common calibration problems of ultrasound therapy devices and emphasized the necessity of device calibration.
Although ultrasound therapy has achieved remarkable results in clinical applications, there are still some gaps in current research. For example, the performance differences between different devices, the stability of the devices during use, and the efficacy of ultrasound therapy on different diseases all need further in-depth research.
Research Design
This study adopted an experimental design to evaluate the compliance of ultrasound therapy devices used in clinical practice by testing their performance. The research data came from multiple medical institutions in a certain region of Canada, and a total of 30 ultrasound therapy devices were collected.
The data collection method includes equipment performance testing and data analysis. The performance test mainly includes the power level of the device, the conversion efficiency of the electrical frequency to the transducer, and the accuracy of the timer. Data analysis evaluates the compliance of the device by comparing the actual performance of the device with the standard performance.
Through the performance test of 30 ultrasonic therapy devices, this study found that:
The power level of 24 devices (80%) differed from the standard value by more than ±20%.
Only 6 devices (20%) had a power level within ±20% of the standard value.
The timer of 9 devices (30%) had errors.
In terms of the conversion efficiency of electrical frequency to transducer, most devices performed well, and only a few devices had obvious errors.
These results show that there are large differences in the performance of ultrasonic therapy devices used in clinical practice, and the power level and timer accuracy of some devices do not meet the standards. This may cause patients to fail to obtain the expected ultrasonic radiation dose during treatment, thereby affecting the treatment effect.
Conclusion and Recommendation
By testing the performance of ultrasonic therapy devices used in clinical practice, this study found that some devices had problems with power level and timer accuracy that did not meet the standards. This result supports the previous view that ultrasonic therapy devices need to be calibrated and emphasizes the importance of device performance to treatment effects.
This study makes the following suggestions:
Medical institutions should regularly calibrate and maintain ultrasonic therapy equipment to ensure that its performance meets the standards.
Researchers should further study the performance differences between different devices and the stability of the devices during use.
When using ultrasound therapy equipment, clinicians should pay attention to the performance parameters of the equipment to ensure that patients receive the correct treatment dose.
Future research can further explore the efficacy of ultrasound therapy for different diseases, as well as optimize the design and production process of ultrasound therapy equipment to improve its performance and stability. At the same time, it is also possible to study the application prospects of wearable ultrasound technology in continuous health monitoring and treatment, and provide new ideas and methods for the development of ultrasound therapy.
