Embodiment Construction

[0054] figure 1 A longitudinal section of the insertion head of the first embodiment is shown. The insertion head comprises a base which in turn has a receptacle or receptacle 1 and a flat part 2 which are integrally formed from plastic. The bases 1 , 2 can be placed with their underside U on tissue. Furthermore, the insertion head includes a two-part handle with a first handle part 10 and a second handle part 12 . The handle part 10 is immovably but releasably connected to the base. The handle part 12 is movably held on the handle part 10, wherein the handle part 12 can not only move linearly relative to the handle part 10, but also move linearly relative to the base 1, 2 . The axis of movement of the handle part 12 is parallel to the underside U of the base 1 , 2 . The direction of movement is indicated by an arrow on the upper side of the handle part 12 .

[0055] The bases 1 , 2 support the introduction device 5 in a pivotable manner about an axis of rotation paralle...

Abstract

The invention relates to a system which is composed of an insertion head and an inserter for placing the insertion head on organic tissue, c) the insertion head comprises: a1) a base (1, 2) having a lower side (U) which can be placed on the tissue, a2) and an insertion device (5) which is movably supported by the base (1, 2), a3) the insertion device (5) is movable in relation to the base (1, 2) from a protected position in which a free end of the insertion device (5) is recessed from the lower side (U) of the base (1, 2) to an insertion position in which the free end projects beyond the lower side (U), and d) the inserter comprises: b1) an inserter housing (20; 30) having an opening for the insertion head on its lower side, b2) a holding device connected to the inserter housing (20; 30) for holding the insertion head in an initial position, b3) a drive (22, 23; 32, 33) by means of which the insertion head can be displaced from the initial position in a direction of advance (V) pointing through the opening of the inserter housing (20; 30), and b4) an activation member (21; 31) that can be moved in relation to the holding device and actuated and which can be used to act upon the insertion device (5) in such a manner as to displace the insertion device (5) in the position of insertion.

Description

technical field [0001] The invention relates to a system comprising an insertion head for medical or pharmaceutical use and an inserter for automatic placement of said insertion head on organic tissue, preferably on human skin. In particular, the insertion head can be a component of an injection set for injecting medicaments. Background technique [0002] An insertion head is known from DE 198 21 723 C1, which comprises a base which in turn has an insertion device protruding from the underside of the base. The introduction device is designed as a flexible sleeve. The piercing needle stabilizes the introducing device while it is introduced into the patient's tissue. As a protection against needlestick injuries, a needle protection is releasably fastened to the base. The process of removing the needle guard is cumbersome. Furthermore, the introduction device protruding from the underside together with the piercing needle and the needle guard considerably increases the pack...
