Medical Textile

Definition: Medical Textile products include textile materials used in hygiene, health and personal care as well as surgical applications.

Properties:The fibres must be nontoxicMust be non-allergenicMust be non-carcinogenicStable on physical and chemical characteristicsWhere necessary biodegradable Where necessary non biodegradable

Products List:Adult diapers Artificial liver Artificial tendon Artificial heart Artificial kidney Contact lenses Incontinence diapers Medical mattresses Sterile medical packaging Surgical disposables Surgical sutures

Wipes Aprons Artificial lung Artificial vascular grafts Artificial heart valves Baby diaper Gauze Masks Nonwoven gowns Plasters Surgical Caps

Medical Textile Fibre:Commodity Fibre:

Natural & Regenerated -Cotton -Silk -Viscose

Synthetic fibre -polyester -polypropylene -carbon etc -PTFE (polytrafluoroethylene) -polyamide -glass fibre

Synthetic fibres are manufactured following away

Medical Textile Fibre:Speciality Fibre

Collagen Calcium alginate ChitinChitosan etc.

Speciality Fibre:

Uses:Artificial tissuWound dressing

Contact lens

Speciality Fibre:

Speciality Fibre:Chitin: This is a polysacharide that is obtain from crab and shrimp shell. It can be absorbed by the body and promote healing. Artificial skin made from chitin non woven fabric stimulate new skin formation.

Chitosan:It is obtained from treating with alkali. It can be spun into filament and the strength of the fibre is similar to viscose rayon. It is being developed for slow drug release membrane.Some other fibre: -polycaprolactone(PCL) -polycapralactone(PPL) mixed with cellulosic fibre.

As highly flexible and inexpensive biodegradable non woven.

According to biological resistance

Biodegradable:Fibre which are absorbed by the body within 2-3 months after implantation and include cotton, Viscose rayon, polyamide, polyamide, collagen and alginate. Biodegradable Stents:

Non biodegradable:Fibre that are absorbed by the body slowly and take more than six months time to degrade are considered as biodegradable .e.g: Polyester , polypropylene, carbon.

According to use and surgical purposes:

Healthcare & hygienic products :Typically used either in the operating theatre or in the hospital wards for hygienic, care and safety of the staff and patients. They could be washable or disposable.

Healthcare & hygienic products :Surgical gown:Surgical masks:It is essential that environment of operating theatre is clean and strict control of infection is maintainedThey should have higher filter capacity, high level of air permeability, lightweight and no allergic.

Healthcare & hygienic products :Surgical caps:Surgical drapes and cover cloths:These are made from nonwoven materials based on cellulose.These are used to cover patients or to cover working areas around patients. It should be completely impermeable to bacterial and also absorbent to body perspiration and secretion from wound.

Extra corporal device:Artificial kidney:Artificial liverTiny instrument, about the size of a two-cell flashlight.Made with hollow hair sized cellulose fibres or hollow polyester fibres slightly larger than capillary vessels.Fabric, which is used to remove waste products from patients blood.

Made of hollow viscose to separate and dispose patients plasmas and supply fresh plasma.

Extra corporal device:Artificial heart:Mechanical lung:An 8-ource plastic pump lined with decom velour to reduce damage to blood and is a chambered apparatus about the size of human heartSilastic backing makes the fabric impervious to emerging gas that is not desirable in the blood.

Made with a hollow polypropylene fibre or a hollow silicone membrane.Used to remove carbon dioxide from patients blood and supply fresh oxygen.

Implantable materials:Textile fibres, yarns, fabrics, composites and 3-D shaped fabrics from woven, knitted, nonwoven, braided and embroidery play a vital role in the manufacture of various implants, including the replacement of diseased or non-functioning blood vessels and segments of aorta or other big arteries. It is even feasible to produce vascular prosthesis as fine as 2-3mm in diameter.

Why textile implants?Biocompatible materialsMaterial combinations2D- and 3D-structuresMechanical characteristic adapted to the environmentAdjustable macroscopic structureSpecific surface design

Non-implantable materialsThese materials used for external applications on the body and may or may not make contact with skin. They are made from co-polymer of two amino acids.This includes wound care, bandages, plasters, pressure garments, orthopaedic belts etc.

Medical textile global scenario:

Medical textile global scenario:It is the 5th in the textile market size with respect to other twelve textile applicationRecently a survey of medical textiles conducted by the tata economy consultancy services has estimated the market size in terms of value 17093 (Rs Mn) in 2005 and it would be 302018 (Rs Mn)Market size of medical textile in India in the value terms (Rs Mn) 2005 is 338. It is estimated up to 575 (Rs Mn) 2010

Europe medical textiles market revenue, by application, 2012 - 2022 (USD Million)

Conclusion:Medical textile products will prevent hospital acquired infection, cross-infection, and provide savings in overall healthcare costs due to reduced cross-infections. Improved Medical textile products will provide comfort and quicker healing.
