  • User interface and method for control of medical instruments, such as dialysis machines
    Patent number: 6146523
    Abstract: A user interface for a medical instrument such as a dialysis machine is described which uses both a touch screen and at least one hard key off of the touch screen to effectuate a change in a parameter associated with the operation of the machine or the treatment session. The user interface is connected to a central computer control system having a host microprocessor and a backup safety microprocessor. The hard key is directly wired to the safety microprocessor. After the user selects a new parametric value on the touch screen, the user presses a hard key. The host and safety microprocessors implement a verification routine to insure that the entered parameter is appropriate for the patient's treatment and the display on the touch screen. If the verification procedure ends in a positive result, the user is prompted to presses a second hard key to confirm the change, causing an additional verification check to be preformed.

  • Dispensing brush head
    Patent number: 5443321
    Abstract: A fluid dispensing brush head includes bristles whose base portions engage apertures in a resilient member to create seal which is disrupted when the bristles are deflected as in use to selectively dispense a fluid. The bristles may be affixed to or form part of a unitary bristle carrier which, along with the resilient member, is removably secured to the body of the brush head so as to permit the brush head to be disassembled and thoroughly cleaned.
