摘要： A flexible envelope for protecting medical appliances against contamination, particularly as when used for the administration, draining or withdrawal of substances, comprising: a highly impermeable and strong flexible backing sheet (11); a layer of padding (12) made of a highly absorbent flexible spongy material which entirely covers one side of said backing sheet (11) and is attached to it by a weld line (at 13), e.g. by hot welding or electrical welding; a flexible nonwoven covering (14) attached to and covering said layer of padding (12) by a weld line (at 15), for example by hot welding or electrical welding, providing a three-layer sandwich pad (16), the peripheral edges of which are turned over on to the free side (14.1) of said covering (14) and are sewn with a seam (17) so as to form a continuous hem (16.1) in relief; and furthermore comprising mutually adhesive but separable sealing means (18.1, 18.2; 23.1, 23.2) which, when said flexible envelope (10, 20) is closed upon itself by being folded along a predetermined fold line (16.3, 21) adhere separably one on top of the other and close said envelope.
