  • Patent number: 11253419
    Abstract: Apparatus and associated methods relate to a wearable compression therapy system for ambulatory therapy, the system including a wearable garment having one or more inflatable chambers, and a pneumatic engine locally coupled to the garment to provide control and inflation of the one or more inflatable chambers. In an illustrative embodiment, the pneumatic engine may control a pump and one or more valves to inflate the inflatable chambers. The valves and pump may be coordinated according to a pre-programmed profile. In some embodiments, the pneumatic engine may have a wireless interface configured to receive control signals from a remote mobile device untethered from the garment. The pneumatic engine may send to the remote mobile device signals indicative of sensed conditions of the compression therapy system. In some embodiments, the pneumatic engine may include a power source that advantageously permits the user to be untethered from a source of power.

  • Patent number: 11089984
    Abstract: A human body support, such as a chair, has a plurality of electrodes arranged in an array and spaced longitudinally with respect to the human body. The array extends from an inferior position to a more superior position along the body. A sensor measures a parameter of the human body that is capable of indicating the presence of drowsiness. A controller has an input connected to the sensor for receiving a signal representing the sensed parameter and has outputs connected to each of the electrodes. The controller detects whether the sensed parameter is within a range indicating the presence of drowsiness and applies a wave of electrical stimuli against the human body in response to detection of a sensed parameter within the range. The electrical stimuli cause periodic tightening and relaxing of proximate muscles as the wave progresses in a direction from an inferior location on the human body toward a more superior location.

    Abstract: A sensory lounging chair system and method of use. The system generally includes a frame, a pump, air tubes connecting the pump to a pair of inflatable air tubes, pressure release valves, piping and hardware, a pressure sensor, and a fabric cover. In a preferred embodiment, the pump and pressure sensor are powered by a power supply connected to a terminal board, which in turn is connected to the pump and the pressure sensor. The fabric cover provides a comfortable barrier between the occupant and the air tubes, which initially are usually deflated or less than fully inflated. As the pressure in the air tubes increase, deep touch pressure is applied to the occupant's body in the places where the air tubes are in contact with the occupant. Deep touch pressure is thus applied to the occupant via contact with the tubes through the fabric cover.

  • Patent number: 9107793
    Abstract: A compression sleeve for being wrapped around a leg of a wearer includes adjacent flexible sleeve sections. At least one of the sleeve sections has an air bladder therein adapted to inflate for compressing a portion of the leg. A structural component is secured to the sleeve and extends generally between the flexible sleeve sections to maintain a spacing of the adjacent sleeve sections lengthwise of the leg when the sleeve is wrapped around the leg. Bladder layers are joined together to form the air bladder. The bladder is joined together at least at two weld points on opposite sides of the structural component to locate the structural component on the sleeve so as to maintain the spacing of the adjacent sleeve sections.

  • Patent number: 9084713
    Abstract: A compression device has improved cooling capability. The device includes a wicking layer adapted to move moisture. A portion of the wicking layer is exposed from under bladder material defining a bladder. In use, the wicking layer wicks moisture from the patient's limb and the wicked moisture is able to evaporate through the device at the portion of the wicking layer that is exposed.

  • Publication number: 20150119773
    Abstract: Tissue compression devices including a multi-chamber bladder that is retained within the tissue compression device, with the multi-chamber bladder being positioned in a bladder orifice in a base of a compression device body. The multi-chamber bladder includes at least one upper chamber located above the base and at least one lower chamber located below the base. The lower chamber is located between the base and a selected location on a patient when the compression device is positioned over selected tissue such as, e.g., a radial artery, as described herein.

  • Patent number: 8992449
    Abstract: A method of forming a compression sleeve for being wrapped around a leg of a wearer includes securing two layers of flexible material together to at least partially define first and second adjacent flexible sections. The securing of the two layers of flexible material includes securing two bladder layers together to define a first inflatable bladder and a second inflatable bladder disposed more proximally than the first inflatable bladder when the sleeve is wrapped around the leg. The first bladder forms at least a part of the first flexible sleeve section and the second bladder forms at least a part of the second flexible sleeve section. The method further includes securing a structural component to the sleeve such that the structural component extends generally between the first and second adjacent flexible sections to maintain a spacing between the sleeve sections lengthwise of the leg when the sleeve is wrapped around the leg.

  • Patent number: 8900168
    Abstract: A body surface compression device for generating cyclical or constant compressions for medical purposes. Compression is accomplished using pneumatic actuated artificial muscle in combination with a belt placed around a body part. Both artificial muscle shortening and pneumatic expansion are used for compression. A unique useful property of this system is the length-tension characteristic similar to natural muscle which reduces applied compressive force proportionally with the level of volume compression of the body part. This property as well as a uniformly applied compression over the body part allows compression to be accomplished in a way which resembles natural muscle activation and minimizes overall abnormal stress on the body part.

  • Patent number: 8870797
    Abstract: A method for improving the cardiac output of a patient who is suffering from pulseless electrical activity or shock and yet still displays some myocardial wall motion including sensing myocardial activity to determine the presence of residual left ventricular pump function having a contraction or ejection phase and a filling or relaxation phase. In such cases, a compressive force is repeatedly applied to the chest based on the sensed myocardial activity such that the compressive force is applied during at least some of the ejection phases and is ceased during at least some of the relaxation phases to permit residual cardiac filling, thereby enhancing cardiac output and organ perfusion. Also incorporated may be a logic circuit capable of utilizing multiple sensing modalities and optimizing the synchronization pattern between multiple phasic therapeutic modalities and myocardial residual mechanical function.
