Abstract: The invention relates to an inserter for an infusion set for intermittent or continuous administration of a therapeutical substance, such as e.g. insulin. The inserter comprises means for insertion and retraction of an introducer needle. With an inserter device according to the invention it is possible to introduce an insertion needle when placing a medical device sub- or transcutaneously. The Inserter device comprises a housing (1, 2, 12) which hides the insertion needle (7, 17) before insertion and can hide the insertion needle (7, 17) after insertion and placing of the medical device. The insertion needle (7, 17) moves relative to the housing (1, 2, 12) toward the patients skin surface during insertion and the inserter device comprises a bi-stable elastic element (1, 11) having two equilibrium states.

Abstract: An assembly according to the invention comprises an inserter device (10), a penetrating member (7) and a base part (100), where: the base part comprises a surface adapted to be attached to a skin surface, a position adapted to receive and/or attach to the penetrating member, and means (14) adapted to secure the base part to the inserter device, the penetrating member comprises a part to be placed subcutaneously or intramuscularly, a body (24) which is in contact with the inserter device during insertion and with the base part during use, and the inserter device comprises a cavity for receiving the penetrating member, means (45) for accelerating the penetrating member and bringing the penetrating member to the receiving position in the base part and means for penetrating the skin of the patient. The length of the joined assembly (1 total) before use is larger than the length of the base part (12) alone.

Abstract: The invention relates to a membrane (17) completely covering an opening (13) giving access to a space in a device which membrane (17) is made of an elastic material penetrable by a needle, the membrane (17) is fastened around the opening (13) and the membrane (17) protrudes from the opening (13) and forms an air filled volume in front of the opening (13) which air filled volume can be reduced in size when a pressure is put on the membrane (17) from the outside, the inner surfaces of the membrane (17) define a passage (17a) at the first closed end of the membrane (17) through which a needle (19) can pass and the second end of the membrane (17) is adapted to attach the membrane (17) to a holding part (61). The walls of the membrane (17) have a thickness and shape of the chosen membrane material making it possible, to maintain the protruding shape in a use position without the outer surfaces of the membrane (17) are supported with walls of rigid material.

Abstract: An inserter for a medical device includes a housing, a carrier body that is movable relative to the housing. The carrier body further including a penetrating member defining a direction of insertion. The inserter including a second body that is movable relative to the housing and driving means that move respectively the carrier body and the second body relative to the housing. The driving means move the carrier body in the direction of insertion and the second body in a direction different from the insertion direction.
