Abstract
A structure for controlling fluid flow from a sample receiving pad into a lateral flow assay test strip, including: a lateral flow assay test strip; a sample pad abutting the lateral flow assay test strip; a pinch wall positioned to direct fluid flow from the sample pad to the lateral flow assay test strip; a top support structure positioned on top of the test strip; and a bottom support structure positioned underneath the test strip, wherein each of the top and bottom support structures comprise a plurality of separate spaced-apart support ribs positioned along the length of the test strip.
Claims12
A pinch wall system for controlling fluid flow movement from a sample receiving pad to a test strip, comprising:
- a sample receiving pad for receiving a fluid sample;
- a test strip in contact with the sample receiving pad;
- and
- a single pinch wall having a first section compressing said sample receiving pad and a second section compressing said sample receiving pad, said second section compressing said sample receiving pad to a lesser degree than said first section, said single pinch wall configured such that fluid flowing to said test strip flows past said second section whereby the flow is controlled.
