Integrated Lancing Test Strip With Retractable Lancet
US Patent:
8328737, Dec 11, 2012
Filed:
Sep 8, 2011
Appl. No.:
13/228163
Inventors:
Daniel Wong - Sunnyvale CA, US
Frank Chan - Sunnyvale CA, US
Frank Chan - Sunnyvale CA, US
Assignee:
Roche Diagnostics Operations, Inc. - Indianapolis IN
International Classification:
A61B 5/00, A61B 17/14, A61B 17/32, B65D 81/00
US Classification:
600583, 600584, 606181, 606182
Abstract:
An integrated lancing test strip device includes a lancet configured to form an incision in tissue and a test strip coupled to the lancet for analyzing body fluid. A retention mechanism acts as a detent to hold the lancet in a static position relative to the test strip before forming the incision. The retention mechanism is configured to release the lancet for retracting the lancet relative to the test strip to reduce smearing of body fluid by the lancet during collection of the fluid with the test strip. In one form, the retention mechanism includes breakable tabs that are broken to release the lancet, and the lancet is retracted via translational movement. The retention mechanism in another form includes one or more dimples that release the lancet when the lancet is retracted via rotational motion. In a further form, the entire integrated device is rotated to collect fluid.

Apparatus And Method For Extracting Bodily Fluid Utilizing A Flat Lancet
US Patent:
2006003, Feb 9, 2006
Filed:
Aug 4, 2004
Appl. No.:
10/911252
Inventors:
Daniel Wong - Sunnyvale CA, US
Charles Raney - Camdenton MO, US
Paul Patel - Sunnyvale CA, US
Steven Roe - San Mateo CA, US
Charles Raney - Camdenton MO, US
Paul Patel - Sunnyvale CA, US

International Classification:
A61B 5/00
US Classification:
600583000
Abstract:
A bodily fluid sampling device is operable to rupture the skin surface at normal and oblique angles utilizing a flat lancet of specified thickness and at least one cutting surface inclined less than eighty degrees (80°) from the longitudinal axis of the flat lancet. The flat lancet thickness and cutting surface geometry minimize pain while maximizing the amount of emerged bodily fluid. The device limits the depth to which the flat lancet penetrates the skin to further minimize pain and may urge the bodily fluid from the rupture site. The bodily fluid emerging from the rupture site is transported to a test device that tests the bodily fluid for particular properties and characteristics.
Integrated Spot Monitoring Device With Fluid Sensor
US Patent:
2012021, Aug 23, 2012
Filed:
Apr 30, 2012
Appl. No.:
13/459697
Inventors:
Daniel Wong - Sunnyvale CA, US
Christopher D. Wiegel - San Jose CA, US
Christopher D. Wiegel - San Jose CA, US
International Classification:
A61B 5/151, A61B 5/157
US Classification:
600583, 600584
Abstract:
A bodily fluid sampling device is operable to breach the skin surface and allow bodily fluid to emerge from the breach location. The bodily fluid sampling device further evaluates the amount of bodily fluid emerged from breach location and determines whether the amount is sufficient or insufficient for a particular purpose, such as sampling and testing. The determination is accomplished automatically without moving the device. The user may also intervene to perform a variety of tasks following the determination of the amount of bodily fluid.

Elastomeric Toroidal Ring For Blood Expression
US Patent:
2008006, Mar 13, 2008

Appl. No.:
11/466202
Inventors:
Paul Patel - Sunnyvale CA, US
Daniel Wong - Sunnyvale CA, US
Daniel Wong - Sunnyvale CA, US
International Classification:
A61B 17/32
US Classification:
606181
Abstract:
An expression device includes an expressing cap that defines a lancet opening. The expression cap has a skin contacting surface that is generally flat and positioned to face tissue during expression of body fluid. The expression cap includes an elastomeric ring extending around the lancet opening from the skin contacting surface. The elastomeric ring is made from elastomeric material. The expression cap has a beveled surface between the lancet opening and the elastomeric ring to enhance expression of the body fluid when the expression cap is pressed around an incision site. It was discovered that when the beveled was angled at about 20°, expression of the body fluid was significantly enhanced.

US Classification:
600583, 53463, 53492
Abstract:
A lancet enclosed in a sterility sheet forms a lancet packet to maintain the sterility of the lancet and prevent the lancet from unintentionally piercing the sterility sheet prior to lancet actuation. In one form, the lancet is immobilized by hot tack welding a portion of the sterility sheet to the lancet. Alternatively, portions of the sterility sheet are hot tack welded together through an opening in the lancet to limit movement of the lancet.
Expression Pad
US Patent:

Frank A. Chan - Sunnyvale CA, US
Assignee:
Roche Diagnostics Operations, Inc. - Indianapolis IN
International Classification:
A61B 5/00
US Classification:
600583
Abstract:
An integrated body fluid sampling device is used to sample a body fluid from an incision in the skin of a body part. The device includes a lancet for forming the incision in the skin. A housing is coupled to the lancet. The housing defines at least in part a capillary channel with an opening. The capillary channel is sized to draw the body fluid from the incision via capillary action. An expression pad is coupled to the housing. The expression pad has opposing angled sides for compressing the backside of a body part where the incision is made. The lancet extends from the housing to form the incision. Fluid from the incision is drawn into the channel and is deposited on the test strip for analysis. A test strip is positioned along the capillary channel for analyzing the fluid.
