COVID-19 has brought the mankind into the worst condition. The health care workers as the forefront player during this pandemic are psychology and physically exhausted. In 2021, the infected patient is decreasing in some countries, yet increasing in others. Therefore, this study is aimed to design and analyze a patient lifting device in order to help the health workers in handling paralyzed and bone traumatic patients in effective way. This lifting device is designed to be operated by only one person and contactless with the patient. Thus, the healthcare worker can work on safety procedure of COVID-19. The structural design of the device is using the concept of crane and hydraulic mechanism that can handle a maximum weight of 2,000 N. Every mechanical part that is considered critical becomes the focus in the strength analysis. The analysis is done by theoretical approach under static and dynamic loading. As the results, the static and fatigue analyses show that the most critical part of the lifting device is at the fork structure with safety factor of 1.04. This indicates the design is in safety condition and could have an infinite service life cycle.

The composites materials are known for their flexibility due to the combinations of two or three different materials and manipulation of their compositions. The advantage offered by composite materials make it suitable for biomedical applications especially to be used for implants. There are three types of composites biocompatible materials namely Metal Matrix Composite (MMC), Ceramic Matrix Composite (CMC) and Polymer Matrix Composite (PMC). In order to produce the biocompatible composite materials, various manufacturing processes can be performed. The manufacturing processes of MMCs are stir casting and powder metallurgy; the typical manufacturing process for CMCs is powder metallurgy; and 3-D printing by synthesizing and cross-linking the networks is used for fabricating PMCs. One of the promising biocompatible composites is Hydroxyapatite Mineralized Collagen (HMC). The HMC is used to create bone scaffold in bone regeneration process. The suggested manufacturing process for HMC is hybrid process which collaborate Additive Manufacturing and CNC Machining. In this paper, the HMC is reviewed especially related with its properties, fabrication method, and existed experimentation. In addition, the three types of biocompatible composites are also discussed on the applications and its manufacturing processes.
