USERS’ PERSPECTIVE

COMBAT & MEDICAL TEXTILES

Gp Capt RK PathniO/o DGAFMS, DG-2Gp

2nd fastest growing

economy &4th largest

We are using more

Population – More People Demography – More People who need Income – More People who can afford Travel -Awareness Medical tourism – Attitudes Growth of healthcare industry – demand Products – Increasing Range of products

SCENARIO• Application of textiles has started going beyond

the usual wound care, incontinence pads, plasters etc.,

• In India, traditionally the segment is dominated by Woven Textiles. Lately, Nonwoven products have provided innovative product options

• Current Domestic Consumption Rs 2365 cr

• By 2012-13 Rs 3737 cr

• Heavily Import Dependent• Unorganized Segment

Why Are Textiles A Good Choice?

Easy handling, manipulating and fashioning Flexibility and suppleness Pores Mechanical strength Good flex fatigue resistance Proven clinical history.

Textile-based materials for medical use are helping to improve people’s lives—and in some cases transform them.

Various types of textiles in medical care

I. Natural Man MadeII. Woven Non-WovenIII. Sterile

UnsterileIV. Disposable Re-

useableV. Patient Non-Patient

In the Patient – Sutures, Implants like Meshes, Extracorporeal Membranes

On the Patients – Surgical Swabs, Dressings

Near the Patient – Gowns, Masks, Caps etc

For the Patient – Wraps for Sterilisation

SMART MEDTEX

• Patient comfort• Hygeinic & non toxic• Ease of usage• Safety• Affordable• Quality• Ease of disposal

Aim

Requirements

In the Patient – Biocompatible, Non toxic, Non Allergenic, Sterility Standards of Highest Level

On the Patient – Non toxic, Non Allergenic, Sterile, Biocompatibility ?!!

Near the Patient – Sterile, Lint free For the Patient – Clean General Properties – Strength, Elasticity,

Durability, Fire Resistance, Antistatic, Biodegradability

Sutures & Ligatures

Easy to handle Good knot security Minimal tissue reaction Unfriendly to bacteria Strong yet small Won’t tear through

tissues Affordable

Absorbable / Non-abs Natural / Synthetic Mono / Multi-filament

Double – barbs Anti-bacterials Staplers Glue

Dressings

Cover Stop bleeding Aid healing Prevent infection Non-linting Soft on granulation tissue Drug delivery Easy to remove Affordable

Vascular Grafts, Mesh, Soft tissue implants Bio-compatibility Anti-coagulant Flexibility, resilience Porosity Texture Mech strength

ISSUES

DISPOSABLES

Resistant to liquid penetration - Blood / Water Non-linting Barrier against bacteria- Dry / Wet Tropicalization – western products are not

automatically suitable

Disposables vs Re-usables

Cost Quality Environmental Issues

waste load resource utilization

In-house QC Safety of users / handlers

Quality Standards

No mandatory standards – D&CA Raw material suppliers Innovation Niche production

Biomedical Waste Disposal

Landfill – Fibreglass Orthopaedic casts

Incineration – Polyurethane Orthopaedic Casting Bandages

Innovations

SPIDER SILK - Exceptional mechanical properties

Tensile strength 1/5th of the density of steel Very high toughness (work

to fracture) Can hold their strength

below −40°C to 220 °C Humidity supercontraction

Five times stronger than steel yet soft enough to be woven into a bulletproof vest.

Toughness : would be able to catch an F-16 aircraft if the silk were as thick as a washing line.
