AI Technical Summary

⚠Technical Problem

Existing methods for manufacturing membrane units, such as lateral flow tests, struggle with positioning errors during the introduction of fluid structures due to the inability to accurately detect deviations from predetermined geometric characteristics, leading to reduced reproducibility and precision in fluid management.

⚗Method used

A method involving a primary manufacturing arrangement that uses a processing tool to introduce a fluid structure into membrane material, coupled with an evaluation arrangement comprising a sensor and control system to generate an evaluation image and data, allowing direct detection of deviations from a reference image, thereby improving accuracy and enabling feedback for future manufacturing adjustments.

🎯Benefits of technology

This approach accurately detects deviations with minimal hardware investment, enhances reproducibility, reduces waste by identifying errors early, and improves the precision of fluid structure alignment, ultimately increasing the accuracy of membrane unit production and reducing costs by optimizing the use of bioactive materials.

Abstract

The present invention relates to a method for manufacturing a roll (1) or sheet of a membrane unit (2) for a membrane product (3), such as a lateral flow test, from a roll (6) or sheet of a membrane material (7) by means of a primary manufacturing arrangement (9), wherein the roll (6) or sheet of the membrane material (7) is processed into the roll (1) or sheet of the membrane unit (2) in a primary processing routine, and in the primary processing routine for generating the membrane unit (2), a fluid structure (11), in particular a hydrophobic structure, for defining the flow of fluid through the membrane material (7) is introduced into the membrane material (7) by a processing tool (12), and the evaluation routine is carried out by an evaluation arrangement (15) comprising a sensor arrangement (16) and an evaluation control (17). In the evaluation routine, an evaluation image (18) of the fluid structure (11) of the membrane unit (2) is generated by the sensor arrangement (16), evaluation data (19) is generated by the evaluation control (17), and it is proposed that the evaluation data (19) represents the deviation of the predetermined geometric characteristics of the fluid structure (11) in each evaluation image (18) with respect to the fluid structure (11) in a reference image (21).
