Patent number: 6777199Abstract: A method for determining the existence and the amount of soluble fibrin contained in a specimen fluid is provided. The method includes the steps of precipitating soluble fibrin out of the opaque specimen fluid, aggregating the soluble fibrin precipitates in a limited region of a transparent container so as to render the precipitates optically detectable in the opaque specimen fluid, and optically detecting the precipitates. The amount of soluble fibrin may be determined by measuring the time from the addition of the precipitating regent to the detection of the soluble fibrin precipitates. Methods of the present invention allow one to measure soluble fibrin in whole blood, and therefore render the test useful in the operating room under conditions of major surgery and in the presence of severe trauma wherein DIC is likely to supervene.Type: GrantFiled: April 29, 2002Date of Patent: August 17, 2004Assignee: Medical Devices CorporationInventors: Brian S.

Patent number: 5716796Abstract: A method for optically measuring the functional capacity of blood platelets and the blood clotting system. The method consists of detection of platelet aggregation in a platelet-containing specimen fluid, whereby the specimen fluid is contacted with a platelet agonist and disclosure reagent. A mechanical specimen-handling apparatus with one or more optical end-point detectors which is preferred for use with the method of the invention is also described. The apparatus incubates a small quantity of diluted whole blood with added solid or liquid reagents at body temperature, and mixes the blood via rocking and rotational motions so as to expose the blood uniformly to the reagents. The optical end-point detectors then measure the activity of platelets within the blood specimen, clotting time, and the clotting cascade. Several intermediate measurements are also available.Type: GrantFiled: January 29, 1996Date of Patent: February 10, 1998Assignee: Medical Devices CorporationInventors: Brian S. Bull, Ralph A. Korpman

Patent number: 4927416Abstract: A user-protective holder for use with a hypodermic syringe comprises a unitary tubular holder member adapted to be received over the syringe barrel, a coupling device for securing the holder member to the finger flanges of the barrel, and a tubular protective sheath received over the barrel in a retracted position in which the needle is exposed for use and movable along the barrel to an extended position in which the needle is received entirely within the sheath such that the sheath protects the user against needle pricks. A releasable latch device couples the sheath to the holder member in the retracted position. The latch device and the coupling device are designed to enable the holder member and sheath to be preassembled to each other before the syringe is inserted into and coupled to the holder member. A spring or a latch device holds the sheath in the extended position.Type: GrantFiled: August 10, 1988Date of Patent: May 22, 1990Assignee: National Medical Device CorporationInventor: Stanley Tomkiel
