Medical textile products

Woven, knitted and braided fabrics for medical textile products are made from yarns that contain fibers, whereas nonwoven fabrics can be made directly from fibers or even polymers. Expanded PTFE fabrics and electrospun webs of micro and nano denier fibers, used in medicine, are examples of products made directly from polymers. All fabrics mentioned vary widely in their construction parameters and, therefore, in the performance characteristics obtained from a given raw material. There is, therefore, a hierarchy of structure. The performance of a final product can be modified from two to four levels of organization. [Pg.228]

The production and utilisafion of textile materials in medical textiles started since the beginning of the civilisation. In time, the function and expectation from textile materials have expanded enormously, and they have developed and formed the final versions for present day. Nowadays, the technical textiles (smart textiles) account for a huge market due to widespread apphcations. Medical textiles are one of the fast growing sectors in technical textiles (Anand et al., 2006). The main expectations from medical textile products should be innovative and beneficial to the patients needs. Table 17.1 illustrates the application of different textile structures for use in... [Pg.445]

From a scientific point of view, medical textiles are located at the interfaces between technical disciplines and life sciences. On the one hand, the technical aspect concerns textile engineering, material chemistry, process control, testing and certification, etc., which are needed for the manufacture of high-quality medical textile products. On the other hand, life sciences such as medicine, microbiology, and other related subjects are required for the development of functional performances of these products. In practice, the different scientific and technical disciplines interact and overlap with one another, with new developments in any one of these branches able to generate new innovations in others. For example, new superabsorbent and gel-forming substances invented in chemistry have been applied in the development of new baby diapers and adult incontinence products. [Pg.15]

Textile materials used for medical applications include fibers, yams, fabrics, and many types of composites, which are processed in many ways to form the medical textile products. As shown in Figure 2.1, the basic constituent for medical textile products is polymers, which are made into fibers through a fiber-making process. These polymers differ from those used in conventional textiles, in that they should possess nontoxicity, nonallergenic response, the ability to be sterilized, good mechanical properties, strength, elasticity, durability, and biocompatibility. Sterility is an essential requirement for medical textile products, and therefore the polymers must be able to withstand the harsh physical and chemical conditions that are generally found in a sterilization process. [Pg.15]

Fibers used in the medical textile industry may vary from natural fibers such as cotton, silk, and regenerated wood fluff to synthetic fibers such as polyester, polyamide, polyethylene, polypropylene, and glass fiber. Table 2.1 shows the applications of different types of fibers in medical textile products. [Pg.15]

For the production of medical textile products for healthcare and hygiene, a number of crucial issues have been identified and debated among clinicians, environmentalists, and pharmaceutical companies for a long time. These issues include ... [Pg.16]

Medical textile products can be divided into four groups depending upon the usage healthcare and hygiene products, extracorporeal devices, implantable materials, and nonimplantable materials. [Pg.17]

The healthcare and hygiene sector is important for medical textile products. Vast numbers of healthcare and hygiene products are typically used either in the operating theater or in hospital wards for the hygiene, care, and safety of staff and patients. They can be washable or disposable. [Pg.17]

Medical textile products used in hospital wards include bedding, clothing, mattress covers, incontinence products, clothes, and wipes. Incontinence products for patients are available in both diaper and flat-sheet forms, with the latter being used for bedding. Cloths and wipes are made from tissue paper or nonwoven-bonded fabrics, which may be soaked with an antiseptic finish. [Pg.17]

Surgical dressings are one of the main types of nonimplantable medical textile products, and are used to cover, protect, and support the injured or diseased body part, and to absorb fluid from wounds. There are five different types of materials. [Pg.20]

Because of the wide variety of products in the medical textiles industry, packaging requirements differ from product to product, and a wide range of materials can be used to pack medical textile products. For the production of wound dressings, individual products are first packed in pouches before being packed into cartons and boxes. The pouches are often made from a combination of paper, polymer film, and aluminum... [Pg.52]

Radiation sterilization involves the exposure of medical textile products to radiations such as electron beams. X-rays, gamma rays, or subatomic particles. Gamma rays are very penetrating and are commonly used for the sterilization of disposable medical... [Pg.53]

As the basic component of medical textile materials, the structures and properties of the constituent polymers have a significant effect on the biodegradability, biocompatibility, absorbency, antimicrobial property, and other functional performances of the final medical textile products. Functional modifications of polymers have far-reaching effects on the fibers, yams, fabrics, and textile materials that are processed in a series of downstream operations. In order to generate the desired product performance characteristics for their diverse applications such as hygiene, protection, therapeutic, nonimplantable or implantable materials, extracorporeal devices, etc., the chemical and physical structures of the relevant polymers should be engineered to suit their required specifications. [Pg.56]

To improve the moisture interaction properties of medical textile products, plasma surface treatment can be used to modify the absorptive characteristics of the textile structure. The treated products have superior moisture-wicking ability which can assist the transfer of moisture in vapor or liquid form quickly from the body into the textile structure. [Pg.62]

Biocompatibility is defined as a measurement of how compatible a material or a device is with a biological system. With medical textile products, the purpose of performing biocompatibility testing is to determine their fimess for human use, and to see whether their use can have any potentially harmful physiological effects. In this respect, medical textile products share the same requirement for biocompatibility as medical devices. [Pg.191]
