Implementation of the Internet of Things in Centrifuge Calibrators

The implementation of Internet of Things (IoT) technology in centrifuge calibrators brings innovation by enhancing accuracy and efficiency in medical device calibration. This research develops an IoT-based centrifuge calibrator capable of storing calibration data digitally and providing real-time access, using the E18-D80NK sensor for rotational motion detection, which is more cost-effective than conventional laser modules. Measurement results demonstrate high accuracy across various RPM settings (1000, 1500, 2000, 2500, and 3000 RPM), with minimal error and stability within acceptable tolerance limits. The key advantage of IoT implementation lies in efficient calibration data management, enabling real-time access and integration with other systems for effective analysis and monitoring of calibration outcomes. Overall, IoT technology in centrifuge calibration not only enhances healthcare service quality with reliable results but also supports efficient and transparent equipment management in medical settings, offering long-term benefits to healthcare facilities and patients.

Calibration of Medical Devices: Method and Impact on Operation Quality

Medical devices play a pivotal role in modern healthcare, aiding in accurate diagnosis, monitoring, and treatment of patients. The reliability and accuracy of these devices are indispensable for ensuring patient safety and well-being. This project highlights the critical importance of calibrating medical devices to maintain their accuracy, precision, and performance, ultimately safeguarding the lives of patients. Calibration of medical devices is a systematic process that verifies and adjusts their measurements to a known standard. This process ensures that medical devices consistently provide accurate data and results. In the absence of proper calibration, there is a significant risk of incorrect readings, misdiagnoses, and inappropriate treatment plans, all of which can lead to patient harm. Regular calibration is essential not only for maintaining patient safety but also for meeting regulatory requirements and quality assurance standards. It helps identify and rectify deviations or drifts in device performance, preventing potential hazards in healthcare settings. Compliance with calibration protocols ensures that medical institutions and professionals can deliver reliable and effective care. Moreover, calibrated medical devices enhance the efficiency and cost-effectiveness of healthcare systems by minimizing the need for repeated tests and procedures due to inaccurate results. Patients can have confidence in the reliability of the devices used in their care, fostering trust in healthcare providers and institutions.

Simulation of Abnormal Physiological Signals in a Phantom for Bioengineering Education

In clinical practice and in particular in the diagnostic process, the assessment of cardiac and respiratory functions is supported by electrocardiogram and auscultation. These exams are non-invasive, quick and inexpensive to perform and easy to interpret. For these reasons, this type of assessment is a constant in the daily life of a clinician and the information obtained is central to the decision making process. Therefore, it is essential that during their training, students of health-related subjects acquire skills in the acquisition and evaluation of the referred physiological signals. Simulation, considering the technological possibilities of today, is an excellent preparation tool since it exposes trainees to near real contexts but without the associated risks. Hence, the simulation of physiological signals plays an important role in the education of healthcare professionals, bioengineering professionals and also in the development and calibration of medical devices. This paper describes a project to develop synchronized electrocardiogram (ECG), phonocardiogram (PCG) and breathing sounds simulators that aims to improve an existing phantom simulator. The developed system allows, in an integrated way, to generate normal and pathological signals, being contemplated several distinct pathologies. For engineering education, it is also possible to simulate the introduction of signal disturbances or hardware malfunctions.

Measurement of the specific heat capacity of liver phantom

Phantoms are often used to simulate tissue during the development, testing and calibration of medical devices. In order to infer the specific absorption rate (SAR) and resistive heating in phantoms from temperature measurements, the specific heat capacity and density of the phantom are needed. Stauffer et al (2003 Int. J. Hyperth. 19 89–101) developed several phantoms that mimic dielectric properties of liver tissue at 915 MHz. However, thermal properties of the phantoms were not presented. We have measured specific heat capacities and densities for these phantoms. We also present dielectric properties for these phantoms measured from 0.7 to 20 GHz, including 2.45 GHz—a commonly used frequency for microwave hyperthermia and ablation.
