  • Patent number: 5129545
    Abstract: An improved tissue container having a dispenser compartment and disposal compartment. The container has a tissue dispensing opening in the dispensing compartment and a tissue receiving opening in the disposal compartment through which soiled tissue may be inserted. The two compartments are formed on opposite sides of a flexible, bag-like liner with the liner opening only at the soiled tissue receiving opening. The bag-like liner prevents contaminants from contaminating the clean tissue compartment. The liner is arranged so that a load of clean tissues in the clean tissue compartment provides supporting structure to keep the liner from snarling and restricting the available space in the disposal compartment.

  • Patent number: 5050600
    Abstract: A battery-powered pacemaker includes an electrical pulse generating device enclosed in a portable case. The pulse generating device is connected to a disposable electrode insertion unit that can easily be inserted in a patient's heart. A relatively short conductive lead connects the pulse generating device and the electrode insertion unit. The case of this pacemaker can be placed on the patient or near the side of the patient but out of the way, thus eliminating the use of the long conductive leads which has been a problem in the past. The present pacemaker also used a male connector on the case to receive a female connector attached to the conductive lead. The male/female connector is used so that blood and other contaminants can be easily cleaned from the male fitting before the unit is reused. Barbless hooks attached to one side of the electrrode insertion unit are used for electrically connecting the pulse generating means device to the heart.
