The publication
44、was in response to demand in the field for a universal standard addressing HAZARDS specific to the safety of the hospital bed. Used in conjunction with a MANUFACTURERS RISK ASSESSMENT, the standard was felt to be the current thinking on establishing a basic safety benchmark for industry. An amendmen
45、t of IEC 60601-2-38 issued in 1999 recognized the need to mitigate against a RISK of PATIENT entrapment in the SIDE RAILS, again combined with the use of the MANUFACTURERS RISK ASSESSMENT. Although this improved the particular standard, it still was centered upon electrically operated hospital beds,
46、 and failed to take into account manually operated hospital beds and products in other medical environments. In 2000, the EN 1970 standard (Adjustable beds for DISABLED PERSONS Requirements and test methods) was published, which addressed beds used by DISABLED PERSONS to alleviate or compensate for
47、a disability or handicap. This standard offered a broadened scope in conjunction with IEC 60601-2-38, but after the edition of Amendment 1 to IEC 60601-2-38, the opportunity presented itself to combine the two standards to a common, international standard. As work began on the integration, the IEC a
48、djusted its stance on BASIC SAFETY and ESSENTIAL PERFORMANCE, integrating them into the third edition of IEC 60601-1. It therefore became necessary to align the new standard with the third edition. The particular standard was given a new number, IEC 60601-2-52, and work began on alignment to third e
49、dition. This particular standard, therefore, is the realization of much work in alignment, and scope adjustment between IEC 60601-2-38, EN 1970, and the third edition of IEC 60601-1. It represents the current thinking in BASIC SAFETY and ESSENTIAL PERFORMANCE of the MEDICAL BED as used to alleviate illness of PATIENTS and disability of DISABLED PERSONS. This is the effort of a join
