MEDICAL TEXTILE

SUBMITTED BY - VICKY RAJ (11110079)TEXTILE TECHNOLOGY7TH SEMESTER

INTRODUCTION

Combination of textile technology and medical sciences has resulted into a new field called medical textiles. It is an important and growing part of the textile industry and is concerned with the medical and related healthcare and hygiene sector. The number of applications are huge and diverse, ranging from a single thread suture to the complex composite structures for bone replacement, and from the simple cleaning wipe to advanced barrier fabrics used in operating rooms.

CHARACTERISTICS OF MATERIAL FOR MEDICAL USE

• Non toxicity

• Nonallergenic response

• Non carcinogenic

• The ability to be sterilized

• Strength

• Elasticity

• Durability

• Biocompatibility

REQUIREMENT OF FIBRE CHARACTERISTICS FOR MEDICAL TEXTILE

• Absorbancy

• Tenacity

• Softness

• Flexibility

• Biostatbility

• Biodegradability (in certain cases)

CLASSFICATION BASED ON USAGE

• Healthcare and Hygiene products

• Extracorporeal devices

• Implantable materials

• Non-implantable materials

Non-implantable materials

• Wound dressings,

• Bandages,

• Plasters

• Gauzes

• Lint

• Wadding, etc.

Implantable materials

• Sutures

• Soft-tissue implants

• Orthopaedic implants

• Cardio vascular implants

Medical Textile Materials

NON IMPLANTABLE MATERIALS

• Used for external application on body.

• This includes wound care, bandages, plasters, pressure garments, orthopaedic belts etc.

Function of the material is to Protection against infection

Absorb blood

Promote healing

Hold dressing in place of wounds.

EXTRACORPORIAL DEVICE

• Used as mechanical organ in human body.

• This includes artificial kidney, liver, mechanical lung.

APPLICATION

Artficial kidney – Achieved by circulating blood through a membrane which act as filter.

Mechanical lung – it have micro porous membrane permeable to gases but low permeability for liquids

Artificial liver – Hollow fibre or membrane same as kidney

IMPLANTABLE MATERIAL

• These materials are used in effecting repair to the body whether it be wound closure or replacement surgery.

• Biocompatibility is of prime importance if textile materials are to be accepted by the body.

• Textile implant is used due to –

Biocompatible material 2D and 3D structureAdjustable macroscopic structureMaterial combination

HEALTHCARE/ HYGIENE PRODUCT

• A vast range of products are available under this category.

• It is typically used in operation theatre , hospital ward etc.

FUNCTION SERVED

Control of infection

Filtering

Absorbant

CONSTRAINT

• Most of the implants are imported

• Indian standards are not available

• Currently research and development are less.

CONCLUSION

Textiles are more and more developing into interdisciplinary high-tech products with interesting changes in the market. Medical Textile Competence Centres are being established to make the most of knowledge, expertise and existing collaboration with medical researchers, microbiologists, physiologists and textile scientists. Each country has its own regulations and standards for medical textiles. As medical procedures continue to develop, the demand for textile materials is bound to grow.
