    Abstract: A device for administering and/or producing medicinal or nutrient solutions, in particular parenteral nutrient solutions, has a multi-path valve (10) the inlet of which is provided with pipe connection (12, 14, 16, 18) linked to at least two reservoirs (20) and that can be individually closed. The outlet (30) of the multi-path valve (10) can be linked to a patient (P). If necessary the multi-path valve (10) has an additional connection (40) that can work as an inlet and as an outlet and to which a syringe-like aspirating device (42) can be preferably linked. For the precise and controlled administration of infusions and to prevent solutions from mixing in the pipe connections leading to the reservoirs, the inlet of the multi-path valve (10) has special individual inlets (22, 24, 26, 28) for each reservoir (20), each individual inlet being provided with a non-return valve (22', 24', 26', 28') that opens only in the direction of the inlet to the outlet (30).

    Abstract: In order to keep the part of a piston-rod (24) projecting from a medical syringe, in particular a perfusion syringe (18), away from infective germs or similar, a hood- or finger-like protective covering (12) of elastically expandable material is drawn over said part and is secured tightly to the syringe cylinder (32) with its free peripheral edge or edge section (16). In order to draw the protective covering (15) over the said operating part (14) of the syringe (18) an expanding cover (10) is used, the inside diameter of which is designed to be somewhat larger than the outside diameter or the maximum outside dimension of the operating part (14) of the syringe (18) and against which the free peripheral edge or edge section (16) of the protective covering (12) is held by using the hood- or finger-like protective cover (12) accompanied by radial pre-tensioning or expansion.

    Abstract: A multipath valve, in particular for medical solutions, has a housing (10) with at least one first inlet (11), one second inlet (17) and one outlet (19), a first flow path being formed between both inlets (11 and 17) and a second flow path between the second inlet (17) and the outlet (19). A non-return valve (15) arranged in the second flow path allows the second flow path to open only in the direction of flow from the second inlet (17) to the outlet (19). To avoid in a reliable manner an incorrect connection between the first inlet (11) and the outlet (19) leading to the patient, an adjustable valve body (13, 13') is mounted in the housing (10) in such a way that it can be moved form a first position, where it opens the first flow path, into a second position, where it opens the second flow path, and vice-versa, at the same blocking the other flow path. The adjustment of the valve body (13, 13') is automatically effected by the instantaneous differential pressure in both inlets (11 and 12).
