Medical instrument with shutter for sealing a test strip port

A medical instrument, wherein the medical instrument is an analyzer for performing a measurement on a biological sample using a test strip, wherein the medical instrument comprises:

• a housing with an exterior surface, wherein the housing comprises an internal surface surrounding a interior volume;
• an analytical unit for analyzing the test strip, wherein the analytical unit is within the interior volume, wherein the analytical unit comprises a test strip mount configured for receiving the test strip to perform the measurement;
• a test strip port between the exterior surface and the interior surface, wherein the test strip port is configured for receiving the test strip, wherein the test strip port is aligned with the test strip mount along an insertion direction;
• a shutter for sealing the test strip port, wherein the shutter is configured for being in an 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, 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, wherein the test strip port has a second sealing surface, 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 for actuating the mechanism to move the shutter between the open position and the closed position;
• wherein the actuator comprises a motor, wherein the medical instrument further comprises a memory for storing machine executable instructions, wherein the medical instrument further comprises a processor for controlling the medical instrument, wherein execution of the machine executable instructions causes the processor to:
• control the motor to actuate the mechanism to move the shutter in the open position;
• analyze the test strip with the analytical unit to perform the measurement when the test strip is inserted into the test strip mount and the biological sample is placed on the test strip;
• and
• control the motor to actuate the mechanism to move the shutter in the closed position when the test strip is removed from the test strip mount and the test strip port.
