Problems solved by technology

Here, however, there is a risk of contamination at the coupling point where the two coupling means of the connector (in the case of a Luer connector, a male luer and a female luer) are connected to each other, so special care must be taken when producing the connection sterile conditions

Embodiment Construction

[0034] Figures 1 to 4 The proposed sterile connector 1 shown in is used for aseptically transferring liquid, in particular biological, media from a liquid container 2 (here a small-capacity liquid container, ie a liquid container with a small holding volume of, for example, up to 30 ml). Transfer to bioprocessing equipment 3 (here bioreactor). The proposed sterile connector 1 has two mechanically and fluidically interconnected coupling devices 4a, 4b, of which one coupling device 4a is associated with a liquid container 2 and the other coupling device 4b is associated with a biological Process technology equipment 3. "Associated" means that the coupling device 4a is connectable or connected to the liquid container 2 and that the coupling device 4b is connectable or connected to the bioprocessing device 3 . It is particularly preferred here that, on the manufacturer's side, to be precise, in the sterile state, on the one hand, the liquid container 2 has been connected to the...

Abstract

The invention relates to a sterile connector for the sterile transfer of a liquid medium from a liquid container (2) to a bioprocess engineering system (3), wherein the sterile connector (1) has two coupling devices (4a, 4b). According to the invention, the coupling devices (4a, 4b) each have a housing (5a, 5b) and an actuator (8a, 8b), which is adjustably mounted in the housing interior (6a, 6b) and forms a channel (7a, 7b), wherein the channel (7a, 7b) extends from an actuator inlet opening (9a, 9b) to an actuator outlet opening (10a, 10b); the housings (5a, 5b) can be mechanically connected to each other and have a fluid inlet (11a, 11b) and a fluid outlet (12a, 12b), wherein, when the housings (5a, 5b) are connected, the fluid outlet (12a) of one housing (5a) and the fluid inlet (11b) of the other housing (5b) overlap; when the housings (5a, 5b) are connected, the actuators (8a, 8b) can each be adjusted from an initial position, in which a fluid connection both between the channel (7a, 7b) and the actuator inlet opening (9a, 9b) and between the channel (7a, 7b) and the actuator outlet opening (10a, 10b) is blocked, to an operating position, in which the actuator inlet opening (9a, 9b) is fluidically connected to the fluid inlet (11a, 11b) and the actuator outlet opening (10a, 10b) is fluidically connected to the fluid outlet (12a, 12b).

Description

technical field [0001] The invention relates to a sterile connector according to the preamble of claim 1 for the sterile transfer of liquid, in particular biological media, to a coupling of the sterile connector according to the preamble of claim 14 coupling device, a packaging assembly having a packaging portion and at least one such coupling device aseptically packaged therein or such a sterile connector aseptically packaged therein according to claim 15, and according to claims 17 Use of aseptically packaged such sterile connector, aseptically packaged such coupling device and / or such packaging assembly. Background technique [0002] A biotechnological plant is here generally understood to mean a device with which a biotechnological process can be carried out or supported. Only by way of example are mentioned bioreactors in which microorganisms or tissue cells are cultured under defined conditions. Such devices usually have a container, in which on the one hand biologic...
