Transversely Arranged Modular Adapter for Fluid Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transfer devices for mixing and administering pharmaceutical substances have limitations such as large structural size, poor space utilization, and the need for pre-use assembly, which complicates storage, transport, and sterility maintenance, and are restricted in application due to specific configurations.
Innovation Solution
A modular adapter system with transversely arranged connection pieces allows for versatile configurations, enabling compact design, ready-to-use arrangements, and easy operation, with features like a cap member, guide means, and ventilation channels to ensure sterility and prevent contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If containers are connected to the adapter shortly before use, then sterility is maintained, but the device cannot be prefabricated and ready-to-use
Solution Approach 1:
The adapter is designed with integrated connection elements and fluid channels that are pre-assembled and sterilizable as a complete unit. The container can be connected in a ready-to-use state without requiring separate assembly of sterility-sensitive components, thus maintaining sterility while enabling prefabrication.
2Ease of operation
If all necessary components are arranged in a ready-to-use arrangement, then handling is simplified, but the structural size increases and space utilization deteriorates
Solution Approach 1:
The adapter design allows the connection piece and fluid channels to be integrated within the container structure itself. The connection element can be positioned inside or along the container wall, and the fluid channel utilizes the container's internal volume, creating a nested arrangement that minimizes external dimensions while maintaining ready-to-use functionality.
3Ease of manufacture
If the adapter is designed for a specific configuration, then manufacturing is simplified, but application versatility is restricted
Solution Approach 1:
The adapter is designed with a standardized connection piece and fluid channel configuration that can accommodate different container types and discharge devices. The connection element is positioned and dimensioned to work with various container geometries, and the fluid channel can be routed to different discharge points, enabling a single adapter design to serve multiple applications without requiring customization.

AI summary
The invention relates to an adapter (1) for a transfer device (20) for a fluid, for the connection of a container (17) containing the fluid, wherein the container (17) is closed by a pierceable closure element (18), and the adapter (1) has an attachment (4) which can be fitted sealingly, in an attachment direction, onto a container mouth closed by the closure element. A penetration element (6) is mounted on the attachment (4) in such a way that the penetration element (6) is movable, with the aid of guide means, between a rest position (R) and a withdrawal position (E), wherein the penetration element (6) has a hollow needle (9) with which the closure element (18) can be pierced in the withdrawal position (E). The adapter (1) has a connector stub (3) with a coupling for the fluid-tight connection of a further adapter (1′), and a transfer channel (10) runs from a mouth on the connector stub (3) to a mouth on the hollow needle (9), such that the mouth of the transfer channel (10) on the connector stub (3) communicates with an interior of the connected container (17) in the withdrawal position (E) of the penetration element (6). The invention is characterized in that the connector stub (3) is arranged transversely, in particular substantially perpendicularly, with respect to the attachment direction (H), preferably on the penetration element (6).
