Biomedical engineering


Biomedical engineering is the application of engineering principles and design concepts to medicine and biology. This field seeks to close the gap between engineering and medicine: It combines the design and problem solving skills of engineering with medical and biological sciences to advance healthcare treatment, including diagnosis, monitoring, treatment and therapy.[1] Biomedical engineering has only recently emerged as its own discipline, compared to many other engineering fields. Such an evolution is common as a new field transitions from being an interdisciplinary specialization among already-established fields, to being considered a field in itself. Much of the work in biomedical engineering consists of research and development, spanning a broad array of subfields (see below). Prominent biomedical engineering applications include the development of biocompatible prostheses, various diagnostic and therapeutic medical devices ranging from clinical equipment to micro-implants, common imaging equipment such as MRIs and EEGs, regenerative tissue growth, pharmaceutical drugs and therapeutic biologicals. Roles of a biomedical engineer in a hospital Advise and assist in the application of instrumentation in clinical environments. Provide leadership, guidance, support and supervision to the section staff and take responsibility in the day to day operation of the clinics. Evaluate the safety, efficiency, and effectiveness of biomedical equipment. Ensure that all medical equipment is properly maintained and documented. Provide engineering and technical expertise on all matters related to medical technology, espec

ally in the process of planning, review, evaluation, and specification of medical equipment. Install, adjust, maintain, and/or repair biomedical equipment. Evaluate, negotiate and manage service contracts. Adapt or design computer hardware or software for medical science uses. Develop and provide a comprehensive in-service education program on the safe and effective use of medical equipment for both medical and nursing staff. Advise hospital administrators on the planning, acquisition, and use of medical equipment. Develop and implement short and long term strategies for the development and direction of the department to effectively manage medical equipment and technology in the clinics. Minimize, investigate and rectify hazard risks associated with medical equipment use. Perform other duties within the scope of the job and its technical capacity and expertise. Tissue engineering Main article: Tissue engineering Tissue engineering is a major segment of Biotechnology. One of the goals of tissue engineering is to create artificial organs (via biological material) for patients that need organ transplants. Biomedical engineers are currently researching methods of creating such organs. Researchers have grown solid jawbones[3] and tracheas from human stem cells towards this end. Several artificial urinary bladders actually have been grown in laboratories and transplanted successfully into human patients.[4] Bioartificial organs, which use both synthetic and biological components, are also a focus area in research, such as with hepatic assist devices that use liver cells within an artificial bioreactor construct.[5]
