Sample collection and testing device with swing arm
View Patent ↗A sample collection and testing device comprising: An elongate housing ( 1 ) having a first end and a second end and a longitudinal axis; an analytical element ( 4 ) retained in the housing; a sample collector assembly extending from the first end of the housing and comprising a sample collector ( 24 ) in fluid communication with the analytical element ( 4 ); a swing arm ( 2 ) attached to the housing by a pivot fitting ( 44 ), said swing arm having proximal and distal ends; and a cap ( 40 ) at the distal end of the swing arm ( 2 ); wherein the device comprises a slide to allow limited linear movement of the cap ( 40 ) substantially along the longitudinal axis of the housing ( 1 ), and wherein the pivot fitting ( 44 ) allows the swing arm to rotate about a pivot axis substantially perpendicular to the said longitudinal axis, whereby the swing arm ( 2 ) is movable between a sample collection configuration in which the cap ( 40 ) is remote from the sample collector ( 24 ) and a sample analysis configuration in which the cap ( 40 ) encloses the sample collector ( 24 ).
1. A sample collection and testing device comprising:
an elongate housing having a first end and a second end and a longitudinal axis;
an analytical element retained in the housing;
a sample collector assembly extending from the first end of the housing and comprising a sample collector in fluid communication with the analytical element;
a swing arm attached to the housing by a pivot fitting, said swing arm having proximal and distal ends; and
a cap at the distal end of the swing arm;
wherein the device comprises a slide to allow limited linear movement of the cap substantially along the longitudinal axis of the housing, and wherein the pivot fitting allows the swing arm to rotate about a pivot axis substantially perpendicular to the said longitudinal axis, whereby the swing arm is movable between a sample collection configuration in which the cap is remote from the sample collector and a sample analysis configuration in which the cap encloses the sample collector.
2. A device according to claim 1 , wherein the swing arm can be pivoted through substantially 180 degrees, whereby the swing arm in said sample collection configuration is substantially aligned with said longitudinal axis with said cap located proximate to the second end of the housing.
3. A device according to claim 2 , further comprising a boss projecting from said second end of the housing, onto which the cap can be fitted while it is in said sample collection configuration.
4. A device according to claim 1 , wherein said slide comprises an elongate opening in the housing or in the swing arm, in which the pivot fitting is retained such that the pivot fitting can slide along the elongate opening.
5. A device according to claim 1 further including a liquid reservoir for releasing a liquid onto the sample collector when the device is in the sample analysis configuration, said liquid reservoir being located within the cap of the swing arm.
6. A device according to claim 1 , wherein the sample collector is mounted on a tubular support that extends from the first end of said housing, and a liquid flow path is provided from the sample collector through said tubular support to the analytical element.
7. A device according to claim 1 , wherein the cap on the swing arm forms a substantially liquid-tight enclosure around the sample collector when the device is in the sample analysis configuration.
8. A device according to claim 1 , further comprising an absorbent element positioned in liquid contact with a downstream end of the analytical element to draw liquid through the analytical element from the sample collector.
9. A device according to claim 1 , wherein the analytical element comprises an analytical test strip.
10. A device according to claim 1 , wherein the housing includes a viewing window for viewing a portion of the analytical element.
