Embodiment Construction

[0028] In Fig. 1a, 1 denotes a body with oppositely directed output connection means 2 and 2' connected to first openings 8 and 8' via channels 3 and 3' respectively, the openings being arranged along a direction parallel to the longitudinal axis of the body. On the plane, this can be obtained by Figure 1b and 1c are more clearly seen. In the region of said plane surrounding the first openings 8, 8' there are respectively first sealing surfaces 9 and 9'. exist Figure 1b Also shown is the holding element 6 located on the main body 1, the element is L-shaped, with a flange longitudinally facing the inside, which together with the plane providing the sealing surface 9, 9' forms a linear guide 7 ( Figure 1b ) are used to cooperate with the parts to be connected to the main body. 4 denotes a connection opening for side access to the guide 7 in a manner to be explained below. When the body according to the invention is intended for implantation, it should preferably be provid...

Abstract

Device for external connection of the bloodstream of a patient to an external circuit or a fluidum source for medical purposes, comprising: a main body with at least a first opening (8, 8') being surrounded by first sealing surface (9, 9') and being adapted to be protected by a removable protective member (24), and a connecting member (10) with at least one second opening (12, 12') being arranged to be protected by a protective body (27) which is removable with respect to the connecting member, wherein the connecting member (10) is connectable to the main body (1) under simultaneous removal of the protective member (24) and the protective body in order to obtain leakproof connection between said openings, wherein the main body (1) is provided with holding elements (6) forming a guide (7) which is open in both ends for the protective member and the connecting member respectively. The invention also concerns a connecting unit for the connecting device.

Description

technical field [0001] The invention relates to a medical connecting device. The invention also relates to a connection unit and a protective unit used in such a device. Background technique [0002] WO 92 / 13590 (corresponding to SE-B-467 769) relates to a device in which the housing is provided with an inwardly facing sealing surface around the connection opening for a connection with the surrounding connection to an external circuit The outwardly facing sealing surface of the conduit opening on the component mates. The sealing surfaces of the housing, as well as the connecting parts, are covered and protected by protective parts in the non-connected state, which are intended to move away from the respective sealing surfaces during the connecting process, thereby exposing the sealing surfaces, in order to obtain a sealed connection. [0003] The purpose of protecting the sealing surfaces is to avoid contamination of these sealing surfaces and of the conduits, thereby avoi...
