  • Patent number: 8460355
    Abstract: A negative/positive pressure, thermal energy therapy device is described in this application. The present invention uses a conventional negative pressure, thermal energy device and/or an alternative embodiment thereof and adds a significant modification. The modification is that positive pressure, not just ambient pressure, is at least occasionally applied to the patient's body contained in the negative pressure, thermal energy device.
    Type: Grant
    Filed: April 5, 2007
    Date of Patent: June 11, 2013
    Assignee: Stryker Corporation
    Inventors: Karl H. Cazzini, Thomas P. Stewart
  • Patent number: 8257414
    Abstract: The present invention is directed to a thermal pump for controlling air bubbles, thermal therapy to allow the patient to perceive that the thermal therapy is constantly being applied, and ensure the appropriate amount of water flows through the thermal pump.

  • Patent number: 8226586
    Abstract: A negative pressure, compression therapy device is described in this application. It has (a) a heel care boot having a fluid, (b) a pressure bag having an opening that receives the patient's foot and the heel care boot, and (c) a vacuum system that generates a modulatable negative pressure in the pressure bag. The negative pressure in the pressure bag is sufficient to cause the patient's veins to vasodilate and the negative pressure modulates to cause the fluid in the heel care boot to provide compression therapy to the patient.

  • Patent number: 7972287
    Abstract: The present invention is directed to a device that provides thermal energy therapy, compression therapy and negative pressure therapy simultaneously and/or in conjunction with each therapy. The outcome of the present invention is that a patient's bodily fluids can be maintained, controlled, and/or adjusted with decreased medication dependence. Using these three therapies individually does not obtain these desired results of controlling, maintaining or adjusting the patient's bodily fluid. This combination of therapies is beneficial to the patient.

  • Patent number: 7164852
    Abstract: The present invention is directed to a fluid warming container (a.k.a., cassette) having an integrated heating element attached to the container, not the warming device as conventionally done. The heating element provides thermal energy to the fluid contained in the container. The fluid contained in the container is designed to be injected and/or delivered, eventually and normally immediately, into a patient.

  • Patent number: 6882797
    Abstract: The present invention is directed to a parenteral fluid warming system. The system has at least first and second fluid warming bags and a warmer device. Each of the at least first and second fluid warming bags have an inlet, an outlet, a top surface, a bottom surface, and a fluid path extending between the inlet and the outlet. In a first embodiment of the present invention, the outlet from the first bag directs the fluid into the inlet of the second bag. In an alternative version of the first embodiment, the first bag and the second bag are a interconnected to each other. The warmer device has at least first and second energy reservoirs that correspond with the number of fluid warming bags. Each energy reservoir also has at least one heater unit.

  • Patent number: 6517510
    Abstract: The present invention relates to regulating the temperature of a desired medium that is applied to the exterior surface of a mammal. These devices have been used in the past but not with the ability to control the temperature of the desired medium in a predetermined ratio to the temperature of the mammal. With such control, the present invention decreases the change of discomforting the patient when the patient's temperature is being brought to a set point temperature body temperature.
