A medical instrument and method thereof for performing a measurement on a biological sample using a test strip are disclosed. The medical instrument may comprise: an analytical unit for analyzing the test strip, wherein the analytical unit comprises a test strip mount which receives the test strip to perform the measurement; a test strip port which receives the test strip, wherein the test strip port is aligned with the test strip mount along an insertion direction; and a shutter movable between open and closed positions, the shutter comprises a test strip opening, wherein the test strip opening is aligned with the test strip port and the test strip mount when the shutter is in the open position, wherein the shutter comprises a shutter mechanism that rotates the shutter parallel to the insertion direction about a rotational axis to move the shutter between the open position and the closed position.

Medical instrument with a shutter for sealing a test strip port

A test element analysis system for analytical examination of a sample. The system comprises a measurement device, which comprises a test element receptacle for receiving at least one test element at least partially, wherein the receptacle comprises at least one first and at least one second part, wherein the first part comprises at least one support surface for placement of the test element, wherein the second part comprises at least one optical detector for detecting at least one detection reaction of at least one test chemical contained in the test element, wherein the second part is movable relative to the first part, wherein the receptacle is configured to position the second part such that a test element may be inserted into the receptacle and to subsequently position the second part in a closed position such that at least one abutment surface of the second part rests on the test element.

Test element analysis system for the analytical examination of a sample

A medical instrument () for performing a measurement () on a biological sample using a test strip (), wherein the medical instrument comprises: a housing () and an analytical unit () for analyzing the test strip, wherein the analytical unit is within an interior volume (). The analytical unit comprises a test strip mount () configured for receiving the test strip to perform the measurement. The instrument further comprises a test strip port () between an exterior surface () and an interior surface (). The test strip port is aligned with the test strip mount along an insertion direction (). The medical instrument further comprises a shutter () for sealing the test port. The shutter is configured for being in a open position and a closed position. The shutter is within the interior volume. The shutter is configured for sealing the test port when in the closed position. The shutter comprises a test strip opening (). The test strip opening is aligned with the test strip port and the test strip mount when the shutter is in the open position. The shutter has a first sealing surface (). The test strip port has a second sealing surface (). The first sealing surface and the second sealing surface are configured to mate in the closed position. The shutter comprises a mechanism for moving the shutter between the open position and the closed position. Moving the shutter between the closed position and the open position comprises a rotation of the shutter parallel to the insertion direction. The medical instrument further comprises an actuator () for actuating the mechanism to move the shutter between the open position and the closed position.

A medical instrument/analyzer for measuring a biological sample using a test strip. The instrument comprises: a housing with an exterior surface, an internal surface, and an interior volume; an analytical unit within the interior volume with a test strip mount; a test strip port between the exterior and the interior surfaces; a shutter configured for sealing the test strip port when closed, wherein the shutter comprises a test strip support aligned with the test strip port and mount when the shutter is in the open position, wherein the shutter has a first sealing surface, the test strip port has a second sealing surface, and the first sealing and second sealing surfaces are configured to mate in the closed position, wherein the shutter comprises a mechanism for moving between the open and the closed position; and an actuator configured for moving the shutter between the open and closed position.
