46、oduction EN 60601-2-52 applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of MEDICAL BEDS for ADULTS, hence not covering requirement for beds for CHILDREN and ADULTS with atypical anatomy. This particular standard is based on the Mandate M/467 Medical beds issued by the European Commision with th
47、e following background information: It appears, from a first analysis undertaken by Competent Authorities, that the current set of standards is not adapted to the needs of CHILDREN or ADULTS with an atypical anatomy. EN 60601-2-52 does not foresee a maximum distance for the bars that is small enough
48、 to prevent accidents. According to the Competent Authorities representatives, a part of the safety problem is due to the fact that medical beds for ADULTS are not appropriately labelled as being designed only for ADULTS with a normal anatomy. Users are therefore not always aware of the risk of medi
49、cal beds for young PATIENTS or for ADULTS with an atypical anatomy. Hospital administrations do not always see a need to buy medical beds which are appropriate for CHILDREN or for ADULTS with an atypical anatomy. Therefore, clear labelling of the targeted PATIENT groups for medical beds complying with EN 60601-2-52 could reduce the risk of inappropriate use of this kind of medical beds for CHILDREN or for ADULTS with an aty
