Patent number: 6183489Abstract: A disposable lancing element is adapted for use in a lancing device for making an incision through a user's skin. The lancing element includes a body which defines a longitudinal axis, and has a skin-lancing member projecting from a front end thereof. A capillary tube is mounted in the body in laterally spaced relationship to the skin-lancing member and is slidable longitudinally relative to the body so as to be extended forwardly past the skin-lancing member. The body includes a plurality of circumferentially spaced, radially outwardly projecting bosses formed thereon for guiding the disposable element installation in a carrier element. The skin-lancing member may comprise a plurality of needles or barbs arranged in parallel side-by-side relationship. In lieu of a skin-lancing member, the disposable element may possess a longitudinal through-hole for conducting a skin-piercing laser light beam or pressurized fluid. A capillary tube may have an outwardly flared lower (inlet) end.Type: GrantFiled: January 28, 1999Date of Patent: February 6, 2001Assignee: Amira MedicalInventors: Joel S. Douglas, Jeffrey N. Roe, Ryszard Radwanski, Brent G. Duchon, Michael J. Sanchez, Henry M. Grage

Patent number: 6099484Abstract: A sampling device for sampling body fluid includes a lancet for making an incision, a capillary tube for drawing-up body fluid from the incision, and a test strip affixed to an upper end of the capillary tube for receiving the fluid. An absorbent pad can be disposed between the test strip and capillary tube for spreading-out the fluid being transferred to the test strip. An on-site analyzer such as an optical analyzer and/or an electrochemical analyzer can be mounted in the device for analyzing the fluid. Alternatively, a test strip can be slid through a slot formed in the bottom end of the device so that by passing the device against the skin after an incision has been formed, the test strip will directly contact body fluid emanating from the incision.Type: GrantFiled: April 23, 1999Date of Patent: August 8, 2000Assignee: Amira MedicalInventors: Joel S. Douglas, Jeffrey N. Roe, Ryszard Radwanski, Brent G. Duchon

Patent number: 6066103Abstract: Body fluid is sampled from a skin incision by placing a ring against the skin and repeatedly applying an elastic pressing force to the ring, whereby a stimulator surface of the ring depresses a ring of skin and body tissue in surrounding relationship to the incision to force body fluid from the incision. The stimulator surface is inclined at an angle of 10 to 65 degrees; a width of the stimulator surface is from 5 mm to 20 mm, and an inner diameter of the stimulator surface is no less than 6.0 mm.Type: GrantFiled: April 1, 1999Date of Patent: May 23, 2000Assignee: Amira MedicalInventors: Brent G. Duchon, Jeffrey N. Roe, Ryszard Radwanski, Joel S. Douglas

Patent number: 6056701Abstract: A device for sampling body fluid includes a housing having a sleeve at a forward end thereof which is displaceable in response to being pressed against a user's skin to trigger the firing of a lancet. After the lancet is removed from the incision, the sleeve is repeatedly pressed against the skin to depress a ring of body tissue in surrounding relationship to the incision to express body fluid outwardly through the incision. A pusher member is then actuated to push a capillary tube through a front end of the housing for drawing-in body fluid. The lancet is a disposable lancet which includes a body supporting a skin-lancing member and the capillary tube. The disposable lancet passes through an upper end of a lancet carrier when being installed or removed. The device cannot be armed until the disposable lancet is installed in the housing, because the capillary tube functions to push a safety device to a non-safety position.Type: GrantFiled: December 3, 1998Date of Patent: May 2, 2000Assignee: Amira MedicalInventors: Brent G. Duchon, Joel S. Douglas, Jeffrey N. Roe, Ryszard Radwanski, Andrew M. Drexler

Patent number: 6015392Abstract: Body fluid is sampled by causing a syringe mounted in a housing to be displaced toward a skin surface. The syringe remains in the resulting incision while the surrounding body tissue is stimulated by a stimulator ring to urge body fluid toward the incision. Simultaneously, the syringe is moved relative to the incision to keep the incision open. Such movement of the syringe may comprise reciprocation in the longitudinal or lateral directions, or both. Alternatively, the movement of the syringe may comprise rotation about a longitudinal center line of the syringe, with the pointed end of the syringe being in the shape of one-half of a cone segment. After the body fluid has been pooled, suction is created in a collection tube disposed in communication with the syringe, to draw body fluid inwardly through the syringe.Type: GrantFiled: September 24, 1998Date of Patent: January 18, 2000Assignee: Mercury Diagnostics, Inc.Inventors: Joel S. Douglas, Jeffrey N. Roe, Ryszard Radwanski, Brent G. Duchon

Patent number: 5948695Abstract: A strip for testing for the presence of an analyte generally comprises a support member which contains a spreading layer and a reagent layer, and a capillary tube in communication with the support layer and spreading layer for transporting a sample of body fluid thereto. A method of testing a fluid for the presence or concentration of an analyte is also provided which generally includes providing a test strip with a support member, a spreading layer, and a reagent layer on the spreading layer. A capillary tube is provided on the support member whereby a fluid containing an analyte to be tested is introduced into the tube and flows through the tube to the spreading layer and contacts the reagent layer.Type: GrantFiled: June 17, 1997Date of Patent: September 7, 1999Assignee: Mercury Diagnostics, Inc.Inventors: Joel S.
