Abstract
Anti-stick device for the safe handling of a needle for transcutaneous injection, this device being formed by two plates (F,D) arranged one above the other and fixed to one another by links (B,C,E,A) such that the device can change from a configuration in which the two plates are pressed against one another to a configuration in which they are spaced apart from one another, providing between them a space surrounded by the said links, and into which the part (17) of the needle which penetrated the skin can be retracted as it is removed.

An anti-stick device for the safe handling of a needle for transcutaneous injection, said device comprising a base plate and a needle-carrying plate arranged one above the other and connected to one another by links such that the device can change from a configuration in which the plates are pressed against one another to a configuration in which they are spaced apart from one another, the needle-carrying plate being suitable for carrying the needle and the base plate being suitable for being pressed against the skin around the point of injection and having a hole for passing a part of the needle which is to penetrate the skin, said space being sufficient to ensure that, during the removal of the needle from the skin and from said hole, said needle part can be retracted into said space as it is removed, said device comprising a single wall which has fold lines that divide the wall into a plurality of sections comprising a central section, which forms said base plate, a section which forms said needle-carrying plate, and end section, and a plurality of linking sections which form said links, the end section comprising two elongate perforations and the needle-carrying section comprising two lateral lugs capable of being folded at right angles to the needle-carrying section and positioned facing one another for being introduced into said perforations when the needle-carrying section and end section are pressed against one another.
An anti-stick device for the safe handling of an elbowed needle having a piercing distal branch and a supplying proximal branch, for transcutaneous injection;
- said device comprising a single semi-rigid and foldable wall having fold lines for dividing the wall into a base wall section, a needle carrying wall section and an end wall section;
- said base wall section and said needle carrying wall section having respective perforations through which the piercing branch of the needle can pass;
- said wall being foldable into one configuration in which said base wall section and said needle carrying wall section are pressed against one another with their respective perforations superimposed for receiving the piercing branch of the needle, and in which the end wall section may be folded over onto the proximal branch of the needle and fixed to the needle-carrying wall section;
- said wall also being foldable into another configuration in which said base wall section and said needle carrying wall section are in spaced relationship for receiving the piercing branch of the needle therebetween when the needle is removed from the skin;
- said needle-carrying wall section comprising two lateral foldable lugs which may be raised to form a grip for enabling the piercing branch of the needle to be pushed into the skin or for extracting said piercing branch from the skin.
