  • Patent number: 7270642
    Abstract: A tubular sleeve (40) comprises an anterior portion (16) of inextensible material that comes to bear against the tibial ridge, and a posterior portion (18) of extensible material covering the region to be compressed. These two portions are connected together along two connection generator lines (20). Inflatable balloons (22) are disposed on the inside face of the anterior portion, being interposed between the inextensible material and the tibial crest. Means (24, 26, 28) are provided for inflating each of the balloons differently to a respective given pressure so as to apply deformation to the anterior portion of the sleeve that is suitable for inducing a traction force that is exerted on the extensible posterior portion; this force is distributed regularly along the generator lines and acts perpendicularly thereto, and consequently leads to compression action on the compressible region of the limb.

    Abstract: An apparatus and methods for the prevention or minimization of lower extremity venous thrombosis comprising an impedance component disposed at the proximal end of the lower extremity and a compression component disposed at the distal end of the lower extremity. The proximal impedance component is activated to impede return venous blood flow, preferably on the femoral vein, until blood volume in the lower extremity is maximized. In response to deactivation of the proximal compression component, the distal compression component is activated to assist return venous blood flow. The apparatus and methods enhance blood circulation in the lower extremity by increasing washout of stagnant blood from the lower extremity, particularly from the venous sinuses and valve cusps where thrombosis tends to form.

  • Patent number: 6921373
    Abstract: The present invention provides an apparatus and method for enhancing the circulation to an extremity of a patient. During the compression phase, the extremity is compressed, pushing out superficial edema as well as emptying the superficial venous tree. The compression cycle is timed to begin at or slightly after the “P” segment of the heartbeat. Air slowly fills a boot so that it reaches maximum capacity just as the heart reaches the diastolic phase in the heartbeat. Since the heart is at its lowest pressure, there is little resistance from the heart, making it easier for the compression of the extremity to push fluids out into the venous structures carrying them back to the heart. When the heart reaches the next full beat, the extremity is void of some of the fluid, forcing from the heart fresh oxygenated blood into the extremity, thereby promoting circulation through the heart.

  • Patent number: 6336907
    Abstract: A massaging system includes a base sheet carrying a plurality of expandable bags arranged in a plane of the base sheet, and a charging and discharging unit connected to the bags for selectively supplying and discharging a pressurized fluid into and from the bags so as to inflate and deflate the bags, selectively. At least one applicator projects from each of the bags in contact with a portion of a human body for applying a massaging action. Each bag has a flexible top end capable of deforming into a curved contour when being inflated. The applicator is made of a hard material and projects directly from the top end wall of the bag as an integral part of the bag such that the applicator is caused to displace in a direction different from a direction along which the bag inflates and deflates principally, as a consequence of that the flexible top end wall deforms into the curved contour.

  • Patent number: 6319214
    Abstract: A valve-less fluid control circuit for controlling rhythmic action devices, such as circulatory assist devices. The fluid control circuit has a plurality of pressure sensitive fluid oscillators for circulating a fluid. Each fluid oscillator includes a capacitance chamber unit for peristaltic pumping of fluid after being filled via an input conduit and a resistance conduit. A first control conduit provides an outlet of fluid from the capacitance unit during peristaltic pumping, and when the pressure of the fluid in the first control conduit reaches a certain level relative to the pressure of fluid in the input conduit, the fluid is directed through an interactive region and exits the first fluid oscillator through an exhaust conduit.

  • Patent number: 6315744
    Abstract: A chair type air massager includes a chair body having a seat, a back rest and a plurality of massage bags embedded therein, and a leg massage device having a pair of leg accommodating grooves and a plurality of massage bags provided in correspondence to the leg accommodating grooves. The leg massage device is capable of moving between a first position where the leg massage device is disposed in front of the seat and is connected to the chair body, and a second position where the leg massage device is separated from the chair body. The leg accommodating groove is capable of accommodating therein at least one leg of a user sitting on the seat of the chair body when the leg massage device is disposed in the first position, and the lower leg accommodating groove is capable of accommodating therein at least one leg of a user who is not sitting on the seat of the chair body when the leg massage device is in the second position.

  • Patent number: 6231532
    Abstract: 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.

  • Patent number: 6171270
    Abstract: An air pressure overall massage apparatus is provided having an air pressure supply, which includes a pump to generate air pressure and a functional can connected with the pump. The functional can is also connected with a pressure switch, an electromagnetic valve, an air delivery hole and a pressure controller individually. There is a time clock used for setting operation time and timing. When air pressure is conveyed through an air delivery hole, it can enter into an air delivery hose to fill massage clothes such as trousers. After the setting pressure imposed on the human body is reached at a setting time, the air will escape for a predetermined number of seconds and then fill again automatically. Thus the human body is repeatedly pressured and relaxed again and again to have overall massage effect.

  • Patent number: 6030353
    Abstract: A multi-function pneumatic chest compression apparatus provides various functions useful in both clinical and treatment environments, including mucous mobilization, breathing assistance, exhaled gas composition, and others. An air flow generator produces preselected air flows depending on the function(s) selected. These air flows are delivered to a bladder positioned about the patient. A controller receives feedback from the bladder and manipulates a valve controlling the flow of air into the air flow generator based on the feedback and preselected operating parameters.

  • Patent number: 5951502
    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.
