Patent number: 7981054Abstract: A device for collecting, shipping and analyzing a pathological specimen comprises a collector stick projecting from the inside of the stopper of a first tubular vessel containing a solution. The bottom of the vessel has a hole sealed by a frangible barrier. When the first vessel is inserted into a second vessel containing a signaling element and having a pintle projecting inwardly from its bottom, the frangible barrier is broken by the pintle and part of the solution flows into the second vessel where it contacts the signaling element. A pin projecting from the inside of a cover for the second vessel punctures the stopper of the first vessel facilitating the flow of solution from the first to the second vessel. The analytical process can be performed in the absence of any contacting or manipulating of the first vessel and specimen collector by simply screwing the cap to its farthest position.Type: GrantFiled: July 16, 2007Date of Patent: July 19, 2011Inventors: Phuong Nguyen, Henri J.

Patent number: 7776023Abstract: An hole-opening implement (5 or 50) for opening a hole in a soft material (2) has a first cutting part and a second cutting part. To pierce the soft material with the hole-opening implement, both cutting parts advances in the soft material while cutting the soft material. Such a state that the second cutting part remains in the soft material just after the first cutting part is passed through the soft material is assured so that a cut piece as bound to the soft material can remain after the opening. The first cutting part is formed at a tip of the hole-opening implement, and the second cutting part is disposed behind the first cutting part in the piercing direction of the hole-opening implement. Otherwise, the hole-opening implement may be constructed so that the first cutting part is sharp in section and the second cutting part is formed so as to have lower cutting force than the first cutting part.Type: GrantFiled: February 3, 2009Date of Patent: August 17, 2010Assignee: Arkray, Inc.Inventor: Yutaka Hatayama

Patent number: 7766879Abstract: A needle assembly includes a transparent or translucent housing with a fluid inlet end, a fluid outlet end, a flashback chamber, and a venting mechanism therebetween. Substantially axially aligned inlet and outlet cannulas extend from the housing and communicate with the chamber. A sealable sleeve covers the external end of the outlet cannula. Relative volumes of the cannulas, the chamber, and the sleeve are selected to provide rapid reliable flashback indicative of venous entry with an internal vent positioned within the housing so as to divide the interior into first and second chambers, with the second chamber being adapted to maintain a negative pressure therein relative to the external environment so as to inhibit leakage of blood from the needle on withdrawal from the patient.Type: GrantFiled: March 7, 2008Date of Patent: August 3, 2010Assignee: Becton, Dickinson and CompanyInventors: Chee Leong Tan, Jon Moh, Stanley Sim Tiong Yee

Publication number: 20100191147Abstract: A piercing device and a blood inspection device that have increased safety. The piercing device (111) has a piercing button (113) placed on the front surface of a first case (112a), a base (114) being a piecing opening provided projecting from the front surface of the first case (112a), and a laser emission device (115) received in the first case (112a). First safety means (117) prevents emission of a laser beam (115a) to the outside when the first case (112a) and a second case (112b) are superposed on each other. When the base (114) is depressed after the second case (112b) is moved from the superposed state where the second case (112b) is superposed on the first case (112a) to a non-superposed state where the second case (112b) is not, a switch (114b) detects the depression of the base (114) and second safety means (118) to enable depression of the piercing button (113).Type: ApplicationFiled: July 31, 2008Publication date: July 29, 2010Applicant: PANASONIC CORPORATIONInventors: Koji Miyoshi, Takeshi Nishida, Yoshinori Amano, Toshiki Matsumoto, Masataka Nadaoka

Patent number: 7758518Abstract: Systems and methods for the expression of bodily fluid from an incision in the skin include devices which bear against the skin in a manner to retain the fluid adjacent the incision site and urge the fluid inwardly toward the incision. Systems utilize a constricting member, a bi-stable expression member, or a pressing member. The present invention further encompasses combinations of the foregoing expression systems with each other, as well as with other expression devices known in the art. Moreover, the invention includes the combination of the expression systems with incising, sampling and/or testing systems, particularly in a single, integrated device. The present invention also contemplates the associated methods for expressing bodily fluid from an incision, including in combination with methods for incising, sampling and/or testing of the bodily fluid.Type: GrantFiled: January 14, 2009Date of Patent: July 20, 2010Assignee: Roche Diagnostics Operations, Inc.Inventors: Edward Perez, Charles C.

Patent number: 7731668Abstract: 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: July 16, 2007Date of Patent: June 8, 2010Assignee: Roche Diagnostics Operations, Inc.Inventors: Joel S.
