摘要:
Body fluid sampling device comprising a skin-piercing element (1) having a collection zone (9) for receiving body fluid, and the device further comprising a fluid receiving means (10) remote spaced apart from said collection zone so that body fluid in said collection zone will not contact the fluid receiving means initially. Said collection zone takes up a very small volume of body fluid of about 10 to 500 nl in a very short time period of less than 0,5 s. Said fluid receiving means may have a test zone for performing an analytical reaction. Fluid sample from said collection zone is automatically or manually transported to said fluid receiving means to contact said fluid with said test zone.
摘要:
A bodily fluid sampling device (30) includes a piercing device (42) and a sensor (56) enclosed in a housing (32). A cassette (54), which contains test media (64), is positioned proximal to the sensor (56) so that the sensor (56) is able to analyze a bodily fluid sample collected on the test media (64). The cassette (54) includes a supply portion (66) from which unused test media (64) is supplied and a storage portion (68) in which contaminated test media (64) is stored after exposure to the bodily fluid. The cassette (54) is adapted to collect a series of bodily fluid samples without requiring disposal of the test media (64).

An integrated bodily fluid sampling device (60) is used to sample a bodily fluid from an incision in skin. The device includes a lancet (62) for forming the incision in the skin. A housing is coupled to the lancet (62). The housing defines at least in part a capillary channel (98) with an opening (100). The capillary channel (98) is sized to draw the bodily fluid from the incision via capillary action. A test size (72) is positioned along the capillary channel (98) for analyzing the fluid. In one form, a flexible sheet (76) extends from the housing proximal the opening (100) of the capillary channel (98) for drawing the bodily fluid into the opening (100) of the capillary channel (98). In another form, the lancet (62) is slidably received inside the channel (98). During lancing, the lancet (62) extends from the housing to form the incision. Fluid from the incision is drawn into the channel (98) and is deposited on the test strip (72) for anaylsis.

A drug delivery device drive that includes a single shape memory alloy wire actuator to advance a lead screw via a ratcheting mechanism and method thereof are disclosed. In one embodiment, a shape memory alloy wire is operably connected to one of a pair of ratchet wheels and configured to drive incrementally the rotation of the connected ratchet wheel via a contraction, which in turn drives the rotation of the other ratchet wheel about a rotational axis which moves a lead screw and advances a plunger to dispense a liquid drug from a drug container. A drug delivery device using the shape memory alloy wire actuator in combination with the ratcheting mechanism to incrementally rotate a shaft, a lead screw or a sleeve provides for a more compact an less complicated design.

A lancet-sampler system is configured to automatically remove a protective cover from a lancet and automatically unpack a test pad just prior to use. This minimizes the risk of injury and reduces the chance of cross-contamination between the lancet and the test pad. The lancet defines a capillary groove for drawing body fluid from the incision via capillary action and a sample transfer opening for collecting the fluid from the groove. A carrier tape is coupled to the lancet. The carrier tape includes a test pad for analyzing the fluid. The tape is folded around the test pad to form an airtight package. The test pad is located at a position to align with the sample transfer opening when the tape is unfolded. The protective cover covers a portion of the lancet, and when the tape is pulled, the protective cover is automatically pulled from the lancet.
摘要:
A bodily fluid sampling device (30) includes a flexible test strip (36), a lancet (32), and a deflection mechanism (44). The test strip (36) is biased to be positioned over the incision site formed by the lancet (32). The deflection mechanism (44) positions the test strip (36) away from the incision site during lancing so as to allow the lancet (32) to have clear access to the incision site. Due to the flexible nature of the test strip (36), after lancing the incision, the test strip (36) returns to the original position so as to collect fluid from the incision.
摘要:
A device (100) is constructed so as to define a capillary channel (120) that draws a body fluid (310) from a proximal portion (160) of the capillary channel (120) toward a distal portion (170). A counterbore (130) defining a “ledge” not substantially normal to the center line (180) of channel (120) causes the meniscus (320) of body fluid (310) to be “ biased “ into a non-radically-symmetric shape. In one example, the bias draws the body fluid (310) toward a testing element that is set into a groove in the main body of the device. In another example, hydrophilic and/or hydrophobic regions are created on or in device to produce the biasing effect. In certain configurations, device (100) requires less blood to be drawn into the capillary channel (120) for a successful test than if the biasing effect were not created.
摘要:
A lancet integrated test element (LIT) includes an incision forming member that has a cutting end configured to form an incision in tissue. A test element is attached to the incision forming member to test fluid from the incision. The test element has a sampling end with a sample opening through which the fluid is collected. The test element is bendable from a first state where the cutting end of the incision forming member is retracted from the sampling end of the test element to a second state where at least a portion of the cutting extends past the sampling end of the test element to form the incision in the tissue.
