Patents by Inventor Kenneth Michael Bolam

Kenneth Michael Bolam has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7252646
    Abstract: A controller for a gradient sequential compression system is provided for inflating a plurality of inflatable chambers of one or more compression sleeves according to several different modes of operation. A mode of operation may define the number and selection of chambers to be inflated, the pressurization levels, the pressurization time, or the sequence of chamber inflation. To enable the controller to automatically perform a designated mode of operation based on the type of compression sleeve connected, a new and improved connecting device is provided. An indicator on an interface connector associates a predetermined mode of operation with the interface connector. A sensor associated with a complementary connector identifies the mode of operation associated with the interface connector. It is contemplated that the universal connecting device can be used for any type of system, not just controllers for a gradient sequential compression system.

  • Patent number: 6786879
    Abstract: A gradient sequential compression system for preventing deep vein thrombosis includes a pressure-based system controller for controlling transfers of air from a source of pressurized air to inflatable chambers of a limb sleeve, so that a prophylactic modality is provided to the limb. The controller also includes a plurality of feeder valves pneumatically connected to each of the chambers and a microprocessor-based control unit for opening only one of the feeder valves at a time during an inflation cycle, so that each of the chambers can be independently inflated to predetermined pressure levels. The control unit also regulates the pressures in each of the chambers at the respective pressure levels by repeatedly independently measuring the pressures in the chambers and adjusting the pressure levels upward or downward, if necessary. The predetermined pressure levels can be default levels or selected by a user or health care professional for a particular application.
