For non EU countries the present document may be used for regulatory purposes. The present document is p
35、art 1 of a multi-part deliverable covering radio equipment in the frequency range 401 MHz to 402 MHz and 405 MHz to 406 MHz for Ultra Low Power Active Medical Devices and implants. This includes Body Worn, Hand-Held, Data systems, etc., the medical section of which is regulated under the Medical Dev
36、ice Directive 10 and Active Medical Implants and Peripherals the medical section of which is regulated under the Active Implantable Medical Device Directive 11 and the radio part of which are regulated under the R Part 2: “Harmonized EN covering essential requirements of article 3.2 of the R provide
37、s additional information. ETSI ETSI EN 302 537-1 V1.1.2 (2007-12) 8 1 Scope The present document covers various individual devices which when operating together form a system operating as a Medical Data Service (MEDS) that provides medical practitioners with therapeutic and/or diagnostic information
38、 used to provide improved medical treatment of a patient and/or to provide an interactive system for patient control of therapeutic devices. MEDS is intended only for transmission of non-time critical data, the loss of which will not compromise the health and/or safety of the patient. Devices covere
39、d by the present document are an evolving new technology to be made available worldwide by the medical equipment industry that will provide high speed communications capability between devices associated with an individual patient that are part of a complete MEDS system as defined in clause 3.1. Exa
40、mples of MEDS devices falling under the scope of the present document are portable body worn physiological sensors that allow ambulatory monitoring, implanted devices and external system devices used to transfer data collected by a MEDS system to medical practitioners who will use the data to diagno
41、se and/or treat a patient. These devices utilize ultra low power radio transmitters in combination with medical devices, the medical portion of which is regulated by the Medical Device Directive (MDD) 10 or the Active Implantable Medical Device Directive (AIMD) 11. The radio part of medical devices
42、regulated by the MDD is hereafter referred to as ULP-AMD, ULP-AMD-P for peripheral devices, and ULP-BWD for body worn devices. ULP-BWD are devices, such as a physiological parameter sensors or handheld devices that are intended to operate in very close proximity to the human body, including touching
43、 the body, the radio antenna of which is external to the body and is used to communicate with a device that is part of a MEDS system. The radio part of medical devices regulated under the AIMD is hereafter referred to as Ultra Low Power-Active Medical Implants (ULP-AMI) and peripherals (ULP-AMI-P) u
44、sed in a Medical Data Service (MEDS). The present document contains required characteristics considered necessary for the radio sections to meet in order to efficiently use the available spectrum for the purpose of transferring data that is used in diagnosing and delivering therapies to individuals
45、with various illnesses. Of particular importance is the inclusion of spectrum monitoring and access requirements (listen before talk protocol) designed to significantly reduce any interference potential between MEDS systems operating in the band or between a MEDS system and the primary users of the
46、band. The present document is a specific product standard applicable to ultra low power transmitters that are part of a system used in the MEDS operating in spectrum within the frequency bands 401 MHz to 402 MHz and 405 MHz to 406 MHz. The present document contains the technical characteristics for
47、ultra low power radio equipment and is addressed by CEPT/ERC/REC 70-03 9 and annex 12 to that document. It does not necessarily include all the characteristics, which may be required by a user, nor does it necessarily represent the optimum performance achievable. It applies to ultra low power system
48、s and accessories operating in spectrum within the bands 401 MHz to 402 MHz and 405 MHz to 406 MHz that operate in the MEDS service: for telecommand and telemetry between any devices that are part of a MEDS (see definition of MEDS); with or without an integral antenna; and/or; with an antenna connec
