Abstract

Each device requires redundancy, including the X-ray machine. In an X-ray machine, there is an important component as the location for the creation of X-rays, namely the X-ray tube. This tube needs routine maintenance to increase the tube's lifetime. In addition, maintenance that was originally done manually, with this device can be done automatically and more quickly. In addition, maintenance that was originally done manually can be done automatically and faster with this device. X-ray tube oil vacuum is used as an effective solution for the maintenance of an X-ray tube machine that lasts for days. This device comes with easy use, equipped with two buttons and a display. This device can increase the productivity of both the device and the technician itself. The application of the use of X-ray tube oil vacuum is intended for hospitals and health facilities that have active X-ray machines. This device has been able to be built. Based on the results, it has a 2.5% error for the measurement at minimum and maximum pressure and a 3% error at -15 KPa pressure. The volume of the X-ray tube fully filled is always the same for each measurement. It can be concluded that this device can be effective in time because it only takes minutes to fill the X-ray tube up to full. Still, many parts can be improved and developed, such as the size and the weight.

Abstract

Background: The knee joint is part of the lower extremity that connects the upper leg to the lower leg. It is the largest and most complex joint in the body. Osteoarthritis (OA) is a slow progressive disease characterized by metabolic, biochemical, and structural changes in the joint cartilage and surrounding tissues, leading to joint dysfunction. Radiographic examination of the knee joint using weight-bearing techniques provides more accurate information for diagnosing osteoarthritis compared to non-weight-bearing techniques. However, at Muhammadiyah Siti Aminah Hospital Bumiayu, this examination was still performed in a supine position due to limitations in bucky stands and the absence of appropriate fixation devices. This study is aimed to design a fixation device for weight-bearing bilateral knee joint examination and to evaluate the performance of the developed fixation device. Method: This research was a quantitative study with an experimental approach. The researcher designed and built a 4-in-1 fixation assistance device that can support the patient, hold the cassette, provide a platform for lateral projection support, and offer handles for patient safety and comfort. Functionality and performance tests were conducted through questionnaires distributed to 6 radiographers at the Radiology Installation of Muhammadiyah Siti Aminah Hospital Bumiayu. The data were processed and analyzed using the Guttman scale and calculated using appropriate formulas. Results: The functionality test results showed a success rate of 93%, while the performance test achieved 86%. The fixation device could support a load of up to 132 kg and was reported to facilitate the examination process by the majority of respondents. Conclusion: The developed fixation assistance device is deemed suitable for use in weight-bearing bilateral knee joint examinations. It effectively supports the efficiency of radiographers' work and enhances patient comfort, although it is recommended that future developments focus on making the device lighter and incorporating adjustable platforms
