  • Patent number: 8486337
    Abstract: A device is provided for analyzing the coagulation and/or behavior of blood. The blood flows through an opening (9) that is disposed in a porous part (5) while a substance which influences blood aggregation can be delivered to the blood. A preliminary diffuser chamber (3) from which blood flows to the opening (9) is mounted upstream of the opening (9), and/or a secondary diffuser chamber (4) into which blood flows from the opening (9) is mounted downstream of the opening (9). The substance is arranged on the wall of the preliminary diffuser chamber (3) and/or the secondary diffuser chamber (4) in the form of a coating (8).

  • Patent number: 6159741
    Abstract: A process and device are disclosed for measuring blood platelet aggregation or blood coagulation. The blood flows through an opening in a part and the occlusion of the opening is measured. The pressure fall (.DELTA.P) formed during occlusion of the opening is measured at predetermined time intervals (dt) and the volume flow (I) is changed to correspond to a predetermined function which simulates the flow resistance (R.sub.v) of a capillary upstream of the opening. Alternatively, the pressure (.DELTA.P) is kept constant during the predetermined time intervals (dt) and afterwards, when the volume flow (I) has diminished by a certain value, the pressure is adjusted until it corresponds to the function.

  • Patent number: 6082798
    Abstract: A robotic gripper, the grippers of which engage as positive-fit elements on a magazine wall. The gripper is used to grip magazines for lead frames. This prevents any pressure stress on the magazines. The positive-fit elements furthermore, because of their shape, prevent the lead frames from slipping out of the magazine under high accelerations.

  • Patent number: 5460779
    Abstract: The invention pertains to a device for the automatic examination of blood samples with one test station, in which blood is taken from a supply vessel and is fed through an aperture in a part held in an aperture holder. At least one test head is provided, to which is fed from a first magazine holder, supply vessels with blood, and from a second magazine holder, aperture holders are fed. After performance of at least one measurement on one aperture holder, the used aperture holder and the used supply vessel are removed from the test head and the test head is cleaned by a cleaning device.

  • Patent number: 5188633
    Abstract: Apparatus for selective destruction or inactivation of cells is disclosed wherein cells are arrayed in a plane for successive illumination, by optical X-Y scanning devices, with a first low powered light beam to produce in particular cells certain radiations responsive to the illumination. These response radiations are detected and used to enable a second higher powered light beam directed through substantially the same optical scanning paths, to destroy or inactivate the cells producing the response radiations. The illumination, response, detection, and high power radiation steps are accomplished by devices acting in times short as compared to the X-Y scanning devices so as to make the accurate treatment of each of large numbers of cells highly effective.

  • Patent number: 5035693
    Abstract: Apparatus for selective destruction or inactivation of cells is disclosed wherein cells are arrayed in a plane for successive illumination, by optical X-Y scanning devices, with a first low power red light beam to produce in particular cells certain radiations responsive to the illumination. These response radiations are detected and used to enable a second higher powered light beam directed through substantially the same optical scanning paths, to destroy or inactivate the cells producing the response radiations. The illumination, response, detection, and high power radiation steps are accomplished by devices acting in times short as compared to the X-Y scanning devices so as to make the accurate treatment of each of large numbers of cells highly effective.

    Inventors: Michael Kratzer, Eberhard Unsold
  • Patent number: 4780418
    Abstract: A method and apparatus are disclosed for measuring the aggregation of blood platelets or the coagulation of blood, the apparatus including a capillary tube for drawing blood, a piston in communication with the capillary tube and connected to a motor means for linear displacement thereof, a pressure sensor in the space located between the drawn blood and piston, and a computing means or microprocessing means for comparing the sensed pressure from the pressure sensor with a predetermined value, and providing a measured regulating output to the motor means. The method for measuring the aggregation of blood platelets and coagulation of blood includes the steps of drawing blood into the capillary tube of the moveable piston until the desired pressure is achieved within the capillary tube, and allowing the computing means to then maintain by adjustment of the piston position the pressure within the capillary tube.
