WHAT ARE BIOMEDICAL TEXTILES?
A biomaterial is defined as a systematic, pharmacologically inert substance designed for implantation or incorporation within the human body and used in contact with tissue, blood, cells, etc.
FIBRES FOR BIOMEDICAL TEXTILES
Natural polymer (biodegradable) –
- Biological protein: Collagen,Catgut,Branan.
- Chitin & Chitosan
- Polyglycolic acid
- Spider silk
- Polytetrafluoroethylene (PTFE)
- PVA, PCL
- Polyurethane urea(PUUR)
- Bamboo fibre
- Viscose, lyocell
APPLICATIONS OF BIOMEDICAL TEXTILES
- Vascular grafts
- Heart valves
- Hernia mesh
- Tissue implants
- Nerve guidance channel
- Corneal lenses
- Artificial skin
- Artificial joints
- Heart patch
- Biomedical smart clothes
Sutures are either monofilament or multifilament with a smooth surface that can pass through the skin without being caught and can be tightened into a single knot.
Absorbable e.g. Polyglycolic acid (PGA), PolytetrafluoroethlyeneNonabsorbable e.g. Nylon, PP, PTFE, shape memory polymer.
Vascular grafts is an artificial vein or artery used to replace segments of the natural cardiovascular system that are blocked or weakened.
- Dacron grafts
- Stability to sterilization
- Resistance to bacteria/viruses
- Nonfraying properties
BIOMEDICAL SMART CLOTHES
THEY ACT AS A HUMAN INTERFACE
Smart clothes with sensors close to the skin. These sensors are enclosed in the layers of the fabric, or at the surface, or they are the fabric itself.
1.Avoid the need for placing the sensors by a nurse or a physician which are put are at the right place.
4.Particularly suitable for monitoring chronic diseases, handicapped persons, elderly people, & professional and military activities.
- Biomedical textiles application are directly related to of human life, which led to the innovative use of fibers & technology for everlasting results.
- Multidisciplinary knowledge in the textile field helps to develop innovative biomedical textiles.
