25、purposes of this document, the following terms and definitions apply. 3.1 stretcher support device that is fitted to the floor and/or sidewall of an ambulance, on which a stretcher or incubator is located Note 1 to entry: Stretcher supports may be manually/power operated and may include a shock abso

26、rbing system. Note 2 to entry: The stretcher support may be equipped with special devices to reduce the effect of acceleration forces of the vehicle to the stretcher or incubator during transportation. Note 3 to entry: The stretcher support may be equipped with devices such as a tilting and extendab

27、le top tray, a fixed or folding ramp. 3.2 stretcher support with manual operation support that can only be moved by using manual force of the operator 3.3 powered stretcher support support that is completely or partially power-operated by means of actuators (electrical, hydraulic, pneumatic, etc.) 3

28、.4 shock absorbing stretcher support support with pneumatic, hydraulic, hydro-pneumatic or mechanical suspension(s) Note 1 to entry: It is designed to cushion the effect of road surfaces, thus providing better comfort for the patient.

29、 expressed in millimetres of permanent deformation and sliding displacement in test direction 4 Requirements 4.1 Edges In order to reduce risk of injury to patients, staff and equipment, there shall be no exposed sharp edges. 4.2 Loading capacity Stretcher supports shall be able to perform all their

30、 functions when loaded with a minimum mass of 220 kg. This load corresponds to the sum of the maximum weight allowed for the stretcher, undercarriage, minimum stretcher loading capacity (see EN 1865-1:2010, 4.2.3 and 4.2.4) and the fixation brackets. Over this weight the stretcher support might not

31、perform all functions, however, it shall be possible to load/ unload the stretcher with a load of 300 kg. NOTE If the manufacturer declares a higher loading capacity, then tests described in Annex B should be performed using the manufacturers advised maximum admissible loading. 4.3 Interface on ambu

32、lance floor or/and sidewall and stretcher support tray The stretcher support manufacturer shall supply the installer with the following data: a) mass and dimensions of the stretcher support; b) position of the centre of gravity with regard to ambulance floor or/and sidewall and the top tray, at the

33、maximum available height; c) position of the fixing points with regard to the centre of gravity, including number of fixing points, type and mechanical characteristics of the connection devices to be used in order to allow the correct positioning of the floor/wall plate reinforcement; d) to withstan

34、d a minimum load of 220 kg according to 4.2; e) identification of the position on the tray where the connecting devices can be fitted (e.g. bolts) without adding any reinforcement. 4.4 Fixation on ambulance floor or/and sidewall and stretcher support tray The fixation shall be in accordance with EN

35、1789:2007+A1:2010, 4.5.9. When tested in accordance with 4.8, there shall be no residual deflection exceeding the values given in Table 1. Table 1 Residual deflection Test axis Maximum deflection value (mm) X+ / X- 125 Y+ / Y- 125 Z 200BS EN 1865-5:2012EN 1865-5:2012 (E) 6 After the test, the stretc

36、her support shall conserve its integrity but not necessarily its functionality. NOTE It is recognized that during the test some components may break. 4.5 Powered stretcher support In the event of power failure, it shall be possible to operate the powered stretcher support manually. If the powered sy

37、stem is fully automated, then an emergency stop button shall be provided in an accessible position. 4.6 Shock-absorbing stretcher support Shock-absorbing supports shall have automatic selfadjusting and self-levelling suspension according to the loaded weight. The maximum time from the activation to

38、completion of the readjustment shall be no greater than 20 s. It shall be possible to lock the shock-absorbing function and set stretcher support in rigid and horizontal position to allow cardiopulmonary resuscitation. In order to avoid sudden, uncontrolled dangerous movements in the event of an ele

39、ctrical power failure it shall be possible to unload the patient and therefore: a) gas accumulators of the stretcher support shall not remain under-pressure; b) the stretcher support shall smoothly discharge the suspension and set the stretcher support in the lowest available position. 4.7 EMC Any e

40、lectrical or electronic items shall conform to EN 60601-1. NOTE If electrical and/or electronic items are used within the system, they should conform to the European Directive 2004/108/EC and any future updates. 4.8 Test method for fixation on ambulance floor or/and sidewall and stretcher support tr

41、ay 4.8.1 General Verification of conformity to 4.4 shall be made with centre of gravity of the dummy assembly adjusted at minimum 700 mm height, when possible, or at full height of the stretcher support when its height is lower. Verification shall be carried out by dynamic testing. NOTE The notified

42、 body which has to confirm the compliance with EN 1789:2007+A1:2010, 4.5.9, in accordance with EN 1789:2007+A1:2010, 5.3 should a) be acknowledged by government authorities according to article 14 of the Directive 70/156/EEC and should be competent in the field of dynamic testing; b) have an acknowl

43、edgement for the Directives 77/541/EEC and 74/408/EEC, and for Directive 96/79/EC.
