Surgical drapes

TTy to avoid contaminating unexposed skin on the patient. Use surgical drapes if necessary. 

Class II—Special Control Class-II devices, such as motorized wheelchairs, infusion pumps, surgical drapes, and some home pregnancy test kits, require additional regulation in order to ensure proper design and performance standards. Such devices may require special labeling and postmarket surveillance. Most medical devices fall into this category. 

Class II devices are those for which general controls alone are insufficient to assure safety and effectiveness, and existing methods are available to provide such assurances. In addition to complying with general controls, Class II devices are also subject to special controls. Special controls may include special labeling requirements, mandatory performance standards, and postmarketing surveillance. Examples of Class II devices include powered wheelchairs, infusion pumps, and surgical drapes. 

Health care Surgical drapes, gowns, and packs, face masks, dressings and swabs, bag liners, etc. 

Examples include insulin syringes, blood pressure gauges, most diagnostic reagents, adult incontinent products, electric heating pads, clinical electronic thermometers, powered wheel chairs, infusion pumps, and surgical drapes.

The various benchmark values set by EN 13795 for surgical gowns, surgical drapes, and clean air suits are found in Tables 5.8—5.10, respectively. The industrial test methods, in addition to common strength tests (tensile, tear, and bursting), comfort, and absorbency, normally carried out on hospital protective textiles are presented in (Table 5.11).

The intentional sparks produced by these machines have also been blamed in a number of surgical drape fires. The high-frequency nature of these therapeutic electrical waveforms also makes it easier for them to become capacitively coupled to other tissue or conductive pathways. Burns due to such coupling and/or insulation failures during laparoscopic procedures are often the result. Since such burns are usually outside the surgeon s visual field, they often go untreated. 

Nonwoven materials are used extensively for drapes and cover cloths and are composed of films backed on either one side or both sides with nonwoven fabrics. The film is completely impermeable to bacteria while the nonwoven backing is highly absorbent to both body perspiration and secretions from the wound. Hydrophobic finishes may also be applied to the material in order to achieve the required bacteria barrier characteristics. The developments in surgical drapes have led to the use of loop-raised, warp-knitted polyester fabrics that are laminated back to back and contain micropo-rous PTFE films in the middle for permeability, comfort, and resistance to microbiological contaminants.

The SiQuat technology is used on a variety of woven and nonwoven textiles used in healthcare facilities. Fenestrations of surgical drapes, mayo stand covers, uniforms, sponges, and linens are among the products that take advantage of the safety profile and antimicrobial effectiveness of this technology. 

Synthetic fibers such as polypropylene and polyester are commonly used in the construction of surgical drapes and gowns as well as viscose. Antimicrobial nonwoven fabrics were prepared by directly incorporation of a qurteroary ammonim salt namely, cethyl trime yl ammonium bromide, on polyester and polypropylene and viscose nonwoven fabrics. An interesting observation is the clear zone of inhibition and excellent reduction of bacteria growth on polyester and polypropylene fabrics. It is apparent that the antimicrobial activity of CTAB is bactericidal in nature and not bacteriostatic. CTAB was effective as antibacterial agent on E.coli for three different fabrics. However CTAB was not effective on S. aureus and P. seudomonas when applied to viscose fabrics which may suggest that nature of substrate influence on the antibacterial activity of CTAB. 

Film and sheeting applications for soft TPV grades include surgical drapes, dental dams, and elastic tapes for wound care in the medical and healthcare arena waist band tapes for clothing and elastic geomembranes in building and construction (Mapleston 2007). 

The proposed mandatory European Standard EN 13795 Surgical drapes, gowns and clean air suits, used as medical devices, for patients, clinical staff and equipment , developed by the Technical Committee (TC) 205 Workgroup (WG) 14, consist of three parts ... 

Surgical drapes are used in the operating theatre to cover the patient and equipment, to protect them from pollutant particles in the air, which carry infective agents. They can inclnde drapes designed for particular surgical procedures and also equipment covers.
