4、 Stretcher trolleys (without top) for indoor use in hospitals In recent years the design of patient trolleys has incorporated various facilities including head end tilting controls, reverse tilt, transfer and radio-translucent tops, side rails, foot rests and other attachments. These modifications a

It is, however, necessary to specify the basic require- ments of patient trolleys, such as their overall dimensions, which have to be considered in relation to the doors and lifts, etc., of the hospital buildings. Dimensional modi- ficatio

8、ns have consequently been necessary, and the standard now includes a recommendation for buffering the patient trolley to protect the fabric of the building. To facilitate the discharge of static electricity, it is essential that the equipment be electrically conductive throughout and that the patien

9、t trolley be fitted with castors having antistatic tyres. The top is also required to be free from any insulating coating or finish, and the accessory fittings are required to be attached in such a way as to maintain metal contact with the framework.
