  • Patent number: 5944494
    Abstract: An apparatus is configured for mounting a blower motor into a blower housing. The blower housing has an interior region for receiving the blower motor. The apparatus comprises a top shell configured to surround a top portion of the blower motor and a bottom shell configured to surround a bottom portion of the blower motor. The top and bottom shells are configured to hold the blower motor in the interior region of the housing without a rigid connection between the blower motor and the blower housing. The top shell cooperates with the bottom shell to define an air intake manifold to provide flow of intake air to the blower motor.

  • Patent number: 5438721
    Abstract: An apparatus and method for managing waste from patient care, maintenance, and/or treatment includes an inflatable bladder member disposed to support at least a first portion of the body of the patient. A flexible basin member is fitted over the bladder and receives waste materials, and a filter sheet is disposed atop the basin member. The basin member is connected to a liquid/gas separator and a vacuum blower. A liquid waste pump is connected to the separator to transfer liquid waste to a holding jug. A vacuum wand provides both suction and rinsing liquid via an on-demand pumping supply configuration that enables the rinsing liquid supplied from a rinse jug to be heated. Liquid levels in the rinse liquid jug, the holding jug, and the separator's holding reservoir are sensed by capacitive level sensing devices which supply signals to a microprocessor which controls various functions of the apparatus. Special inflatable sacks are provided to assist turning the patient to facilitate cleansing of the patient.

  • Patent number: 5425148
    Abstract: A bed footboard has a main body with a cavity that is configured to receive a panel and a pocket member behind the panel to store patient records. The panel is pivotally mounted in the cavity to permit access to the pocket member and records held in the pocket. The panel is slidable in the pivotal mounting and has a retaining lip that can be engaged to a retaining flange in the cavity to enable the panel to be retained partially within the cavity and disposed to serve as a writing surface. The panel has a biased retracting mechanism that enables the panel to be released from the pivotal mounting. The main body of the panel has channels in which bolts can be slidably extended above the top surface of the main body. The panel has openings configured to receive the bolts to enable the panel to be mounted above the top surface of the main body and serve as a utility tray.
