摘要:
Adjustment mechanisms are used in conjunction with integrated lancet test strips to adjust the position of the drive system, engagement system, or the drive coupling in a fixed stroke lancing system to thereby adjust the penetration depth of the lancet. In a variable drive stroke lancing system, the lancet penetration depth is adjusted by changing the stroke length of a drive system. The stroke length of a drive system is adjusted by rotating a cam or sliding a cam in a cam type drive system. In either the fixed or the variable drive stroke lancing system, the test strip and/or guidance foil of the integrated lancet test strip is immobilized while the lancet is actuated.

A lancing device includes a housing (10, 12) for receiving in use a replaceable lancet (34) introduced into said housing, a drive (58, 59) actuable to drive the lancet momentarily to project its tip from the housing, and a nose portion (14) having an aperture through which said lancet projects when fired. The nose portion is threadedly engaged (78, 81) with the forward end (10) of the housing to allow the penetration depth of said lancet tip to be pre-set, and is resiliently deformable between a position in which it is locked against rotation and a position in which it is free to rotate.

A body fluid sampling system for use on a tissue site includes a single drive force generator. A plurality of penetrating members are operatively coupled to the force generator. The force generator moves each of the members along a path out of a housing with a penetrating member exit, into the tissue site, stops in the tissue site, and withdraws out of the tissue site. A flexible support member couples the penetrating members to define a linear array. The support member is movable and configured to move each of the penetrating members to a launch position associated with the force generator.

An analyte and detecting apparatus includes a housing, an access door and a front end aperture. A module is positionable in the housing. A penetrating member is positioned in the module and upon launch passes through the front end aperture. An analyte sensor is positioned in the module. A penetrating member driver is configured to be coupled to the penetrating member. A mechanism is included that moves an arm coupled to the penetrating member driver into a launch position and allows motion of the penetrating member driver.

A lancing device includes a main barrel portion 10 to the front end of which is hinged a forward portion for movement between the open position shown in FIG. 1 and a closed position. The main barrel portion 10 contains a drive mechanism, cocking slider and trigger, while the forward portion contains a lancet holder into which a lancet may be loaded front end first. Also disclosed is a lancing device having a main housing having a forward nose portion to the rear of which is a flip up lancet hatch into which a lancet may be loaded front end first.
摘要:
A test unit for carrying out blood analysis includes a lancing element that can be pricked into a body part which has a capillary channel for transporting the body fluid that leads from a lancing member to a target site. A pretensioned distal sterile cover and a liquid permeable proximal sterile cover are proposed for the lancing element that is advantageously formed as a deep-drawn component.

The medical puncturing device includes a housing, a shield, and a skin puncturing assembly disposed within the housing. The shield is axially movable in the housing. The skin puncturing assembly includes a movable carrier and a skin puncturing element mounted to the carrier. A distal end of the skin puncturing element is adapted for puncturing the skin of a patient. The carrier is movable from a retracted position wherein the skin puncturing element is disposed within the shield to a puncturing position wherein the distal end of the skin puncturing element is exposed. The carrier is maintained in the retracted position by engagement of flexure members or a retaining tab with the carrier. A drive spring is provided to move the carrier from the retracted position to the puncturing position. A retraction spring is provided to return the carrier and skin puncturing element into the housing.

Provided is a portable diagnostic test apparatus including: an accommodation portion including an outer side, an inner side, and an accommodation space provided on the inner side; a hinge; and a main body coupled to the accommodation portion by the hinge, where the portable diagnostic test apparatus is configured to be opened and closed by rotating one of the accommodation portion and the main body about the hinge, and where the main body is configured to obtain a result of a measurement based on data collected from drawn blood. The main body and/or the accommodation portion includes at least one strip keeping portion configured to store at least one strip. The at least one strip keeping portion may include: a housing; a discharge portion; and a first movement portion configured to move one of the strips to the discharge portion.
摘要:
A blood sample test device has a continuous strip sensor which is advanced through the device so that multiple blood sample tests can be conducted on a single strip. The device is provided with a sprocket having an encoder which engages sprocket holes on the strip to precisely control the advancement of the strip through the device.
摘要:
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.
