DIN EN 13795:2013-10 EN 13795:2011+A1:2013 (E) 4 Introduction The transmission of infective agents during invasive surgical procedures can occur in several ways (see informative Annex C). Surgical drapes, including the intended use as a ste

28、rile field, surgical gowns and clean air suits are used to minimize the spread of infective agents to and from patients operating wounds, thereby helping to prevent post-operative wound infections (see Annex C). The performance required of coverings for patients, clinical staff and equipment varies

29、with, for example, the type and duration of the procedure, the degree of wetness of the operation field, the degree of mechanical stress on the materials and the susceptibility of the patient to infection. The use of surgical gowns with resistance to the penetration of liquids can also diminish the

30、risk to the operating staff from infective agents carried in blood or body fluids. EN 13795 is intended to assist the communication between users, manufacturers and third parties with regard to material or product characteristics and performance requirements. It focuses on Essential Requirements ari

31、sing from the Medical Device Directive 93/42/EEC which are applicable to surgical drapes, gowns and clean air suits. The requirements and guidance in EN 13795 are expected to be of help to manufacturers and users when designing, processing, assessing and selecting products. It is the intention of EN

32、 13795 to ensure the same level of safety from single-use and reusable surgical clothing and drapes throughout their useful life. DIN EN 13795:2013-10 EN 13795:2011+A1:2013 (E) 5 1 Scope This European Standard specifies information to be supplied to users and third party verifiers in addition to the

33、 usual labelling of medical devices (see EN 980 and EN 1041), concerning manufacturing and processing requirements. This European Standard gives information on the characteristics of single-use and reusable surgical gowns, surgical drapes and clean air suits used as medical devices for patients, cli

34、nical staff and equipment, intended to prevent the transmission of infective agents between patients and clinical staff during surgical and other invasive procedures. This European Standard specifies test methods for evaluating the identified characteristics of surgical drapes, gowns and clean air s

35、uits and sets performance requirements for these products. EN 13795 does not cover requirements for flammability of products. Suitable test methods for flammability and resistance to penetration by laser radiation, together with an appropriate classification system, are given in EN ISO 11810-1 and E

36、N ISO 11810-2. Additional essential requirements that apply to surgical clothing and drapes are covered by other European Standards. 2 Normative references The following referenced documents are indispensable for the application of this document.
