Fluid Connector Protective Cover for Biopharmaceutical Piping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In biopharmaceutical applications, existing fluid connectors with clamps can cause damage to flexible pipes and bags due to sharp edges, leading to leakage and loss of sterilization during transport or handling, and they do not provide a satisfactory aesthetic or secure connection.
Innovation Solution
A fluid-connection device with a protective cover that snap-fits over the pipe clamp, preventing direct contact with external elements and ensuring proper coupling of connectors, while allowing easy installation even with aseptic protective equipment, and featuring a radially symmetrical design for secure positioning and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pipe clamp is used to secure the flexible pipe to the nozzle, then the connection reliability is improved, but sharp edges on the clamp can cause damage to the flexible pipe or bag
Solution Approach 1:
The patent introduces a protective cap as an intermediary element that fits over the pipe clamp. This cap has a smooth interior surface that contacts the flexible pipe or bag, preventing the sharp edges of the clamp from causing damage while maintaining the secure connection provided by the clamp.
Solution Approach 2:
The protective cap is installed beforehand to cover and cushion the sharp edges of the pipe clamp before the flexible pipe or bag comes into contact with the clamp. This prevents potential damage from occurring in the first place.
2Strength
If the clamp is made robust and reliable (metal clamp with crimping), then the connection strength is improved, but the crimping process creates burrs or roughness that form sharp edges
Solution Approach 1:
The protective cap serves as an intermediary that covers the harmful burrs or roughness created during the crimping process. The smooth interior surface of the cap prevents these sharp edges from contacting and damaging the flexible pipe or bag.
3Ease of operation
If the clamp is made accessible and easy to install, then the ease of operation is improved, but the clamp can be easily removed or accessed which may compromise security or aesthetics
Solution Approach 1:
The protective cap is designed to fit over the existing pipe clamp, creating a nested structure. The cap has an open end that allows easy installation over the clamp, while once in place, it provides a secure cover that prevents unauthorized access or removal, thus maintaining both ease of installation and connection security.

AI summary
Disclosed is a fluid-connection device for connecting a first wall defining a first fluid space, in the form of a flexible pipe, to a second wall defining a second fluid space, in the form of a flexible or rigid disposable pipe or enclosure, in a biopharmaceutical assembly, including a first connector in fluid communication with the first space, the first connector including a tubular nozzle for receiving the pipe by insertion along the axis A, a pipe clamp arranged around the end of the pipe in order to clamp the pipe onto the tubular nozzle of the first connector, a protective cover forming a separate part, capable of being snap-fit in an operative position in which the cover is at least partially surrounding the first connector and the pipe clamp thereof, by way of which the pipe clamp cannot come into direct contact with external elements.
