Patent number: 4309112Abstract: A method and apparatus for the detection of the magnitude of selected chemical substances in a biological fluid by fixed rate analysis. Photometric analysis is performed sequentially upon a standard solution and then upon an unknown sample to determine the rate reaction in each. The method and apparatus minimize or eliminate error in equipment drift and calibration. The rate reaction is manually initiated in a standard solution carrying a known amount of a chemical substance. The standard is then placed into a photodetector circuit to produce a voltage representing optical density which increases at a constant but unknown rate during the reaction. The time required for the voltage to change from a base-line level to a selected and pre-set value is then measured and stored as a calibration reference time.Type: GrantFiled: August 18, 1980Date of Patent: January 5, 1982Assignee: Sherwood Medical Industries Inc.Inventors: Holvor W. Ashley, Vincent H. Li

Patent number: 4215700Abstract: A blood collection device used in taking a small sample from a patient for test purposes is provided with a capillary tube and vented tube holder disposed in the upper end of a blood collection container. Integral radial extensions allow the container to be centrifuged in a centrifuge normally used for containers of larger diameter. An integral flexible strap connects a stopper to one of the radial extensions so that the stopper remains with the container.Type: GrantFiled: August 25, 1978Date of Patent: August 5, 1980Assignee: Sherwood Medical Industries Inc.Inventors: Ronald Crouther, Vincent H.
