SENSOR DISPENSING DEVICE

A sensor dispensing device (1) comprises a cartridge (2) having an outer casing (11) and a plurality of sensors (6) arranged one upon another in a stack. The cartridge has a first dispensing end (13) and a second opposing end (14) spaced a fixed distance apart, and the cartridge includesa first aperture (15) for the ejection of a sensor closest to the first end and a second aperture (16) opposed to the first aperture, for access by a pushing member (25). The first aperture and the second aperture are each provided with compliant sealing means (17) which are at least partly disposed outside the outer casing. The sealing means have first and second sealing surfaces which are capable of co-operating to releasably form a substantially moisture-tight seal when acted upon by suitable clamping forces. The device has a housing (34) for receiving the cartridge. For each of the compliant sealing means (17) there is a pair of clamping members (4, 33) for releasably clamping the sealing means to form a substantially moisture-tight seal. The device has a pushing member (25) for reversible insertion through the second aperture when the sealing means are not clamped, for pushing the sensor closest to the first end through the first aperture to a dispensed position.
