Patent number: 9532919Abstract: A method for augmenting blood flow in a limb that is wrapped with a sleeve having at least one chamber for applying compression to the limb in a region generally underlying the chamber includes pressurizing the chamber to a first compression pressure and then reducing the pressure to a refill pressure. Pressure in the chamber is then sensed to determine a first venous refill time. The preceding steps are repeated a second and other times using second and other compression pressures that are different from the first compression pressure and from each other to determine second and other venous refill times. A customized compression pressure is determined by locating the compression pressure at which blood flow out of the region generally underlying the chamber is maximized by finding compression pressure at a maximum venous refill time. A compression device employing such a method is also disclosed.Type: GrantFiled: July 23, 2013Date of Patent: January 3, 2017Assignee: Covidien LPInventors: Malcolm G. Bock, Kristin L. Watson

Publication number: 20150094628Abstract: A compression garment includes fluid-impermeable bladder layers defining an inflatable bladder. A ventilator is at least partially disposed on an inward side of the inflatable bladder. The ventilator at least partially defines at least one passage between the wearer's skin and the inward side of the bladder and in fluid communication with atmospheric air at a location outside of the compression garment when the compression garment is worn on the wearer's body part. The ventilator is flexible to collapse the at least one passage under the force of inflation of the bladder and to resiliently expand the at least one passage upon deflation of the bladder. The collapse of the at least one passage expels air from the at least one passage to the atmospheric air and the expansion of the at least one passage draws the atmospheric air into the at least one passage.Type: ApplicationFiled: September 27, 2013Publication date: April 2, 2015Applicant: Covidien LPInventors: Peter Crowley, Kristin L.

Patent number: 6231532Abstract: A method for augmenting blood circulation in the limb of a patient is provided by customizing the compression cycle based upon patient venous characteristics. The method measures the venous refill time of the patient for use with an intermittent pneumatic compression device. A limb such as a leg is wrapped with a compression sleeve having at least one pressurizable chamber. The chamber is pressurized for a predetermined period of time to compress the limb and cause blood to flow out of the limb. The chamber is depressurized until the pressure in the chamber reaches a lower value, and the chamber is closed. The pressure in the chamber is sensed and the venous refill time, the time for the limb to refill with blood, is determined by sensing when the pressure reaches or will reach a plateau. The venous refill time is used as the basis for the time between subsequent compression pulses of the compression device.Type: GrantFiled: October 5, 1998Date of Patent: May 15, 2001Assignee: Tyco International (US) Inc.Inventors: Kristin L.
