A disposable cartridge adapted to be used with a sensor-dispensing instrument comprises a housing, test sensors, a mechanical mechanism and moveable seals. The housing forms at least one opening therethrough. The test sensors are stacked in the housing. The test sensors are adapted to assist in testing at least one analyte. The mechanical mechanism is adapted to urge the test sensors in a first direction. One of the test sensors is positioned for ejection from the cartridge. The moveable seals is adapted to be in a closed position that seals the at least one opening so as to provide a substantially moisture-proof and a substantially air-tight cartridge, and one of the moveable seals is adapted to be in an open position that allows one of the test sensors to be moved therethrough.

Cartridge and sensor-dispensing instrument

A meter for determining the concentration of an analyte in a fluid sample comprises a memory device, electrical circuitry and a detection device for distinguishing between an alternative site test and a standard site test. The memory device is adapted to store information. The electrical circuitry is adapted to determine the analyte concentration of the fluid sample located on a test sensor. The electrical circuitry is in electronic communication with the memory device. The electrical circuitry communicates the determined analyte concentration to the memory device for storage.

Marker for readings taken from alternative site tests

A lancing mechanism is adapted to move between resting, cocking and puncture positions and comprises a lancet holder, a shaft, at least one spring and a mass. The shaft is attached to the lancet holder and has an enlarged end opposite the lancet holder. The spring surrounds at least a portion of the shaft and has first and second portions. The second portion of the spring is attached to the lancet holder. The spring drives the lancing mechanism between the cocking and puncture positions. The mass is located along the spring with the first and second portions of the spring extending on opposite sides of the mass. The mass is distinct from the lancet holder. The first portion dampens the lancing mechanism when moving from the puncture position to the resting position.

Single-puncture lancing system

A lancing device comprises a housing, a trigger button, a drive spring and a protective cap. The housing forms an aperture and an opening opposite thereof. A lancet partially extends through the aperture. The trigger button is located near the opening. At least a portion of the trigger button is external to the housing. The drive spring is attached to and connects the lancet and the trigger button. The drive spring moves the lancet from the cocked position to the puncture position. The protective cap is removeably attached to the lancet opposite the drive spring and engages the housing when the cap is removeably attached to the lancet. The cap prevents the drive spring from moving the lancet to the puncture position prior to removing the cap from the lancet.

Single use lancing device

A glucose monitoring system comprising a readhead positioned a predetermined distance from a sample aperture. The readhead comprises first and second LEDs adapted to emit intersecting paths of light. A beam splitter is positioned at the intersection of the light paths. The beam splitter comprises a band pass filter for controlling the center wavelength of a resulting coaxial emitted light for illuminating a sample on the sample aperture. The readhead further comprises a detector which comprises a detector aperture and a molded lens over the detector aperture. A light-scattering section upstream of the lens comprises a plurality of steps having angles greater than 90 degrees to reduce internal stray light.

Diffuse reflectance readhead

It has been discovered that the use of a substantially free-standing voice coil within a lancing device in coordination and combination with a stationary magnet and electronic circuit renders a much improved lancing device. The minimal weight of the free standing voice coil and the attractive forces of the magnet allow the battery-powered electronic circuit to maintain excellent control over the advancement and retraction of a lancet. When the electronic lancing device is initiated by a user, the voltage source within the electronic lancing device provides sufficient current through the voice coil such that the coil and lancet are repulsed from the magnet and propelled into the puncture site. The voltage source subsequently reverses the current through the voice coil to supply sufficient attractive current through the voice coil such that the dwell time of the lancet is minimized and the lancet is retracted from the puncture site and pulled toward the magnet within the housing of the electronic lancing device.

Diagnostic analyzer

A diffused light reflectance readhead is disclosed. The readhead employs an improved light emitting diode (LED) providing a more strongly collimated beam of light around a beam axis onto a reagent test pad. The reagent test pad is supported on a strip guide at an angle .alpha. of 5 degrees with respect to the perpendicular of the beam axis. It has been discovered that when .alpha. is between 3 and 8 degrees that specular reflection is dramatically reduced in relation to the small reduction in reflected light received by a sensor. The diffuse reflected light travels to the sensor by passing through a staircase optical baffle at an angle of 45 degrees to the perpendicular of the beam axis. The sensor converts the optical signal into an electrical one for processing and analysis. One embodiment of the present invention can detect the presence of glucose in a blood sample.
