Abstract

A blood glucose monitor includes a can, a replaceable sensor cartridge that includes a frame, an upper spring disposed between the frame and the can, a case for housing the can and sealing the frame, a lower spring disposed between the can and the case, and a meter housing for sealing an upper portion of the frame. The can is capable of accepting the replaceable sensor cartridge. The frame of the removable cartridge has at least at least two walls defining a chamber for accepting a plurality of biosensors, and a bottom portion defining an opening and at least one sealing flange. The frame can further include a desiccant material capable of reducing humidity within the frame. The frame may be dimensioned such that an interference fit constrains the plurality of biosensors prior to inserting the frame within a blood glucose monitor.
