BIOLOGICAL FLUID MEASURING DEVICE

摘要

A biological fluid measuring device for determining the presence and the amounts of substances in a biological fluid without the need for dilution of the fluid comprises a main housing (12) including electronic circuit means (24) and at least one electrode (28, 30 and 32), and a cartridge (14) having a membrane (34). The cartridge (14) is removably mounted on the housing (12) and the membrane (34) is operably associated with the electrode (28, 30 and 32). The cartridge (14) also includes means (36) for protecting the membrane (34) when the device is not in use.
