  • Patent number: 9889063
    Abstract: Methods and systems are disclosed for determining patient compliance for using a compression therapy device. The systems may include a compression therapy sleeve and a controller having a non-transitory memory device. During a therapy session, the controller may record in the memory device operational therapy data obtained from sensors associated with the controller and/or sleeve. The controller may calculate a compliance metric based in part on the therapy data. The controller may then communicate the data or metric to one or more recipients. The methods may include allowing the patient to transfer a removable memory device from the controller to a personal computer, and uploading the therapy data or metric stored on it to a recipient website. Alternative methods may include the patient receiving the metric from the controller at the end of the therapy session, and then providing the metric to a recipient by phone.

  • Patent number: 9532919
    Abstract: 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.

  • Patent number: 9364386
    Abstract: A support surface system provides alternating pressure therapy and low air loss therapy simultaneously using a single pump. The system includes a plurality of cells. Each cell has a foam-filled lower chamber and an upper chamber. Fluid communication between the lower and upper chambers is controlled by a normally closed valve that opens if the pressure within the lower chamber exceeds a predetermined threshold pressure. Pressurized air is alternatingly supplied to the lower chambers of a first subset of cells and the lower chambers of a second subset of cells, thereby providing alternating pressure therapy. When the pressure in the lower chamber exceeds the threshold, the valve opens to allow air from the lower chamber to flow into the upper chamber. Air is expelled from the upper chamber through perforations therein, to remove moisture and humidity and possibly reducing the temperature of the micro-climate beneath a patient.

  • Patent number: 9238426
    Abstract: A seat having a backrest and a seat cushion is provided with at least one adjusting element on both sides of the longitudinal center plane of the seat. By alternatingly actuating the adjusting elements in the two halves of the seat, mobilization of the spinal column of a seat user occurs. In order to increase the acceptance of such a mobilization, which requires comparatively long stroke lengths of the adjusting elements to achieve a physiological effectiveness, an accustomization phase occurs before the action phase. During the accustomization phase, the adjusting elements exercise, for example, only about half of the stroke during the action phase. Preferably, a transition phase may be interposed between the accustomization phase and the action phase.

  • Patent number: 9226705
    Abstract: A human body support, such as a chair, has a plurality of support segments that are arranged in an array. Each support segment has a protrusion elevation that is independently variable and controllable in its distance of protrusion elevation against the supported human body. A sensor is connected to a human body on the support and senses a human body parameter that can indicate the presence of drowsiness. A controller analyzes the sensed parameter to detect whether the sensed parameter is within a range indicating the presence of drowsiness. The controller applies a wave of varying segment protrusion elevation against the human body in response to the detection of drowsiness. The wave progresses in a direction from an inferior location on the human body toward a more superior location. Alternatively, a wave of electrical stimuli is applied by similarly positioned electrodes and causes periodic tightening and relaxing of proximate muscles.

    Abstract: A boot assembly and method that simulates, in a static equine animal (stalled or hauled), the natural mechanical action of walking or other gaited exercise. The assembly has a boot, containing a shock absorbing pad that is fitted with dual pulsing bladders disposed under or inside the shock absorbing pad. Pressuring and relaxing the pulsing bladder in the bottom of the boot rhythmically pushes against the sole and frog and against the toe of the equine hoof in much the same way that the hoof is exercised when the animal is moving. The pulsing action helps stimulate blood flow through the hoof and is beneficial to shod, injured, and transported horses. The assembly may be fitted on one or more hooves, and may be automated to provide timing and sequencing to simulate different gaits of the animal. In some aspects the assembly is disc posed in an ice boot or ice spa boot to also provide cryotherapy as well as simulated exercise.

  • Patent number: 8579841
    Abstract: An adjustable pressure cuff device is provided for the arm or leg of a user for stimulating blood flow and preventing blood clots. The pressure cuff contains a number of bladders which wrap in the direction of the cuff and which are arranged in succession down the arm or leg of a user. An air compressor is connected to the bladders via a multiplicity of tubes, each of which contain a valve. A control module runs the air compressor and sequentially opens the valves to provide air pressure to the bladders in succession along the arm or leg of a user. Further, between the bladders and the valves, additional tubes containing valves are provided to equalize pressure between bladders before exhausting the air from a previously pressurized bladder to save power and allow for increased patterns of bladder pressure. The pressure levels and bladder dwell times may be adjusted by the user or based on predetermined settings. Optionally, the device provides electrical stimulation, pulsations, heating, and cooling.

  • Patent number: 8523794
    Abstract: An apparatus and method for treatment of patients suffering from lymphedema. The apparatus includes a multiple chamber sleeve positioned in a wrap around fashion on a body extremity to be treated. The chambers are sequentially inflated and maintained so until all chambers are inflated and then all the chambers are simultaneously deflated except the proximal end chamber to move edema fluids out of the afflicted area. The apparatus includes the capability of applying interferential therapy either alone or in combination with compression therapy. Advantageously, the sleeve chambers capture pressurized air when applied thereto, at designated locations, so as to form air pockets that can selectively apply isolated points of pressure, and in combination with the application of electrical current to a patient's affected area, provide effective lymphedema therapy without disrupting normal vascular and lymphatic functioning.
