The invention provides for a medical instrument (2500, 2600) that is an analyzer for performing a measurement (2513) on a biological sample using a test strip. The medical instrument comprises: a housing (102) with an exterior surface (104), an internal surface (106), and a interior volume (108); an analytical unit (2508) within the interior volume and for analyzing the test strip with a test strip mount (2510); a test strip port (112) between the exterior surface and the interior surface that is aligned with the test strip mount along an insertion direction (128); a shutter (114) for sealing the test strip port, wherein the shutter is configured for being in a open position and a closed position, wherein the shutter is within the interior volume, wherein the shutter is configured for sealing the test strip port when in the closed position, wherein the shutter comprises a test strip support (130), wherein the test strip support is aligned with the test strip port and the test strip mount when the shutter is in the open position, wherein the shutter has a first sealing surface (118), wherein the test strip port has a second sealing surface (120), wherein the first sealing surface and the second sealing surface are configured to mate in the closed position, wherein the shutter comprises a mechanism for moving the shutter between the open position and the closed position, wherein moving the shutter between the closed position and the open position comprises a rotation of the shutter perpendicular to the insertion direction; and an actuator (2506) for actuating the mechanism to move the shutter between the open position and the closed position. |
