Devices for detecting analytes in fluid sample
First Claim
1. A device for detecting the presence or amount of an analyte in a fluid sample comprising:
- a sample collector comprising a compressible absorbent member for collecting the fluid sample, at least one test element having reagents for detecting the presence or amount of the analyte in the fluid sample, and an extender element positioned between the absorbent member and the test element and defining an elongated fluid passageway between the absorbent member and the test element; and
a receiving cup reversibly coupled to the sample collector for receiving and holding the sample collector within the receiving cup, the receiving cup having a sidewall, a first open end for engaging the sample collector, a second end opposing the first open end, and a sampling hole through the wall separate from the open end, the sample collector having a first position and a second, locked position within the receiving cup, the compressible absorbent member being uncompressed in the first position and being compressed and held within the cup in the second, locked position, and wherein transition from the first position to the second position causes extraction of the fluid sample from the compressible absorbent member and flow of a portion of the fluid sample along the elongated fluid passageway to the test element via a compressive force generated between the extender element and the second end of the receiving cup.

Abstract
A device for detecting the presence or amount of an analyte in a fluid sample and method thereof, comprises a sample collector and a receiving cup for receiving and holding the sample collector within the receiving cup. The sample collector contains a compressible absorbent member for collecting the fluid sample, and has a first position and a second, locked position within the receiving cup. The absorbent member is uncompressed in the first position and is compressed in the second, locked position. The sample collector or the receiving cup has at least one test element having reagents for detecting the presence or amount of the analyte in the fluid sample.
