This disclosure provides equipment and processes for blood glucose management. Embodiments may comprise a lancet device that includes a base that supports a lancet and a cover. The cover can move controllably from an un-depressed position to a depressed position when a predetermined force is applied. The cover can provide access to the lancet in the depressed position. In another aspect, a biological test kit may include a reusable module and a disposable module. The disposable module may include one or more lancet devices such as that described above to collect a biological sample, one or more strip stations supporting biological strips and a disposable module connector. The reusable module may support measuring equipment to measure a property of the biological sample and a reusable module connector that engages removably with the disposable module connector.
摘要:
Needle assembly having the following modes of operation; a first mode wherein the safety shield can move to a first retracted position allowing injection of the piercing portion of needle from a position at least partially covering the piercing portion of the needle and a second mode wherein the safety shield moves to a position protecting the piercing portion of the needle after the first mode and is prevented from moving back to a position exposing the piercing portion of the needle.

The invention relates to a lancet for performing an incision. The lancet has a blade for providing an incision and a trigger housed in a housing. The trigger has a first trigger arm, a second trigger arm and a flexible member connected to the second trigger arm. A resilient member may be disposed within the housing in a pre-cutting state in which it stores energy and arranged to exert a force for moving the second trigger arm and the blade from a first stowed position through a cutting position and to a second stowed position.

A lancet device includes a hollow housing defining a cavity and having a proximal end and a distal end and a slider slidable at least partially within the cavity along a longitudinal axis from an outward position to a pushed position. The slider extends outside of the cavity beyond the proximal end when it is in the outward position. A needle holder holding a needle is rotatable about and translatable along the longitudinal axis when moved from an initial position to an extended position. When the needle holder is in the initial position, the slider is in the outward position. When the needle holder is in the extended position, the lance extends beyond the proximal end. Sliding of the slider to the pushed position enables a first biasing member to urge the needle holder toward the extended position. A second biasing member can be present in the lancet device.
摘要:
A lancing device for sampling blood or other body fluid of a subject includes a reusable housing and a disposable cassette. The cassette contains a plurality of lancets held in a storage plane. An active lancet is moved transversely from the storage plane into a firing plane, into engagement with a drive mechanism for actuation to lance the subject's skin. After actuation, the used lancet is returned to the storage plane. Each lancet includes a protective endcap that is removed from the lancet just prior to use and then is replaced onto the lancet after use.
摘要:
A lancing device and a removable and replaceable multi-lancet cartridge for use in connection therewith are disclosed. The multi-lancet cartridge is advanced through sequential lancets, and anti-reverse features prevent reverse advancement of the cartridge. Interlocks are provided to prevent double-cocking the device, to reduce the likelihood of jamming of the mechanism. Improved trigger mechanisms and depth control mechanisms are provided.
摘要:
A method and collection and transport device for collecting biological samples, such as a blood sample, from a subject wherein the method and device include a body having a slide member mounted therein and movable from a first position wherein a collection well of the slide member is aligned to receive a sample from the subject to a second position wherein the sample communicates with a chemical reagent contained within a cavity of the body. The sample well and chemical reagent cavity are sealed from the exterior of the body when the slide member is in the second position. In preferred embodiments, locking means are provided to retain the slide member in the second position. In some embodiments, a lancet mechanism may be provided with the transport and collection device.
摘要:
A lancet actuator device and mechanism for sequentially advancing and retracting a lancet blade include a housing having an opening for operating projection of the lancet blade. The actuator mechanism includes a drive spring structure insertably mounted in the housing and arranged to drive pivotal motion of the lancet blade including sequential thrusting of the blade from the housing aperture followed by immediate pivotally reverse retracting of the blade from the aperture into the housing as the spring deengerizes.
摘要:
A needle device and method of use are disclosed, wherein the needle moves out of and into a protective housing, between two operative positions, one of which causes the housing to shield the needle. Each operative position includes releasable locking detents to temporarily hold the needle in one of those positions, the holding force of one being less than the other. A third position beyond the one that shields the needle in the housing is used to permanently lock the needle in the housing against accidental reuse. The needle device can be used with a blood collection container or a syringe drug delivery container, each one releasably mating with the device during use.
