Autoclave

Biomedical device technology ,by ANTHONY Y. K. CHAN, MSc, MEng, PEng, CCE

Autoclave is an instrument used moist heat sterilization techniques by using steam in the range of 121-134°C. Steam under pressure is used to generate high temperature needed for sterilization. Saturated steam (steam in thermal equilibrium with water from which it is derived) acts as an effective sterilizing agent. Steam for sterilization can be either wet saturated steam (containing entrained water droplets) or dry saturated steam (no entrained water droplets).

 

Oven

The oven is a device used in a laboratory for drying and sterilizing glass and metal containers or materials used for examinations or tests performed in the laboratory. The ovens operate between room temperature and 350 °C. They are also known as hot air oven.

 Operation Principle 

Centrifuge

Biomedical device technology ,by ANTHONY Y. K. CHAN, MSc, MEng, PEng, CCE

The centrifuge uses centrifugal force (the force generated when an object rotates around a single point), for separating solids suspended in a liquid by sedimentation or liquids of diverse density. The rotational movements allow forces much greater than gravity to be generated in controlled periods of time. Centrifuges are generally used in the laboratory in processes such as the separation of solid components from biological liquids through sedimentation and for conducting multiple tests and treatments.

Introduction about the laboratory design

Biomedical device technology ,by ANTHONY Y. K. CHAN, MSc, MEng, PEng, CCE

Good design in laboratories plays a critical role in ensuring safety, efficiency, and compliance with standards. A well-planned laboratory considers the specific scientific and operational needs of the research or medical work that will be conducted within it, whether it's in a healthcare setting, an academic institution, or an industrial facility. This lecture will cover the basic principles of laboratory design, including layout, safety, equipment, and environmental considerations.

 

Patient Safety

Patient safety is preventing and minimizing risks, errors, and harm to patients during the delivery of healthcare services.

Principles of patient safety 

  •  Focus on improving systems
  •  Continuous learning and training to enhance evidence based practices

Design of an Operating Room

Biomedical device technology ,by ANTHONY Y. K. CHAN, MSc, MEng, PEng, CCE

The design of an operating room (OR) plays a crucial role in ensuring patient safety, improving surgical outcomes, and enhancing the efficiency of healthcare professionals. A well-designed OR minimizes infection risk, optimizes space for equipment and personnel, and allows for smooth workflows during surgeries.
