Patent number: 7374544Abstract: These and other objects of the present invention are achieved in a body fluid sampling system for use on a tissue site that includes an electrically powered drive force generator. A penetrating member is operatively coupled to the force generator. The force generator moves the member along a path out of a housing having a penetrating member exit, into the tissue site, stops in the tissue site, and withdraws out of the tissue site. An analyte detecting member is positioned to receive fluid from a wound created by the penetrating member. The detection member is configured to determine a concentration of an analyte in the fluid using a sample of less than 1 mL of the fluid.Type: GrantFiled: December 31, 2002Date of Patent: May 20, 2008Assignee: Pelikan Technologies, Inc.Inventors: Dominique M. Freeman, Dirk Boecker, Don Alden

Patent number: 7288082Abstract: A method and apparatus are provided by which a fluid may be drawn and packaged within a series of interconnected sterile units. Once filled with the fluid, the connectors joining the sterile units may be sealed and severed to produce a number of separate sterile units. The volume of the separate sterile units may correspond to a single dose of the fluid. The technique allows a fluid to be partitioned into sterile units without exposure to the air or other potential contaminants.Type: GrantFiled: October 17, 2002Date of Patent: October 30, 2007Assignee: SeeFit IncorporatedInventor: Richard W.

Patent number: 7252642Abstract: A method for measuring the total sperm concentration (TSC) in a sample is described and includes: (i) placing the sample in a transparent container between a synchronically pulsed light source and a photodetector; and (ii) measuring the optical absorbance of the sample in the range of 800-1000 nm, the TSC of the sample being proportional to the absorbance. Also described is a sampling device for use in optically analyzing a biological fluid, a method for measuring motile sperm concentration (MSC) in a semen sample, a method of determining the average velocity (AV) of sperm cells and a system for analyzing semen quality including means for measuring TSC, means for measuring MSC; and a video visualization system.Type: GrantFiled: May 24, 2001Date of Patent: August 7, 2007Assignee: M.E.S.

Patent number: 7244236Abstract: A specimen trap including a container forming a chamber. A strainer is fixedly positioned within the chamber and defines an upper portion of the chamber and a lower portion of the chamber. The strainer has a porous surface that provides fluidic communication between the upper portion and the lower portion. One tube connection is mounted to the cap and forms a passage through the cap and another tube extends through the cap and through the strainer into the lower portion. The cap is rotatable with respect to the container to form communication between one of the specimen compartments and the one tube connection passage for collection of an independent specimen.Type: GrantFiled: May 17, 2004Date of Patent: July 17, 2007Assignee: M D Technologies inc.Inventor: William L. Merkle

Patent number: 7097623Abstract: A method for drawing a biological sample using a suction-discharge device, such as a manual or automatic pipette, built into an automated device or not. A method for detecting the free surface of a biological sample and/or solid, a sample drawing device such as a pipette and a device for detecting the free surface of a biological sample or a solid are also disclosed. This method includes actuating a means causing a pressure variation or an air flow within the suction-discharge device, positioning the lower free end of the device in such a way so that it becomes flush with a free surface of the biological sample, measuring an overpressure within the suction-discharge device, and sampling a quantity of the sample by suction using the device. The invention finds a preferable application in the field of automatic analyzers.Type: GrantFiled: August 14, 2003Date of Patent: August 29, 2006Assignee: Biomerieux S.A.Inventors: Bruno Colin, Cécile Jaravel, Marie Privat

Patent number: 7070579Abstract: A luer connector is described that is angled away from the patient's scalp in the direction of the drip assembly line. In the preferred embodiment, the luer connector has a female luer connector that mates with a male luer connector on the drip assembly line. The luer connector also has a hollow protrusion that extends into a catheter thereby allowing the luer connector to be fluidly connected to the catheter. A fluid passage is formed through the angled luer connector from the female luer connector, through the body of the angled luer connector and through the hollow protrusion. The luer connector has a pair of “wings” that extend outwardly from the luer connector and allow the luer connector to be sutured to the patient's scalp.Type: GrantFiled: April 30, 1998Date of Patent: July 4, 2006Assignee: Medtronic, Inc.Inventor: Derek J.

Patent number: 6699199Abstract: A ring plethysmograph having a pressure adjustment for locally pressurizing one side of a finger thereby biasing the pressure on an artery wall so that the plethysmograph is optimally sensitive without interfering with blood flow. An auxiliary photodetector, possibly with a second light source, is disposed on the low-pressure side of the finger for two purposes: providing a noise reference for canceling noise on the plethysmograph signal, and also for providing a separate motion signal for monitoring the activity level of a patient.Type: GrantFiled: June 11, 2002Date of Patent: March 2, 2004Assignee: Massachusetts Institute of TechnologyInventors: Haruhiko H.
