  • Patent number: 11752062
    Abstract: A pneumatic module has an air passage formed therein, including an air inlet to receive a source of pressurized air, a first subsystem with an air splitter in fluid communication with the air inlet, a second subsystem, and a third subsystem. The air splitter is configured to create two unequal air pressure fields to deflect an airflow from the air inlet to the second subsystem. The second subsystem is configured to create two unequal air pressure fields to deflect the airflow toward a first air bladder to inflate the first air bladder, and when the first air bladder reaches a first threshold air pressure, a first backpressure from the first air bladder causes the second subsystem to switch and deflect the air flow to a second air bladder. A second backpressure causes the air splitter to switch and deflect the airflow from the second subsystem to the third subsystem.

  • Patent number: 11628110
    Abstract: Various aspects of the present disclosure are directed to an apparatus and/or method involving respective sets of interleaved pressure cells, which operate to inflate and deflate independently of one another. The pressure cells further provide shear relief by deflecting along a direction of movement, such as along a shear direction of an upper surface coupled to the pressure cells. Such deflection may, for example, be implemented with elongated pressure cells and along a direction that is perpendicular to a length thereof. Shear relief in this regard may be facilitated by undercut regions of the respective pressure cells, at which location the pressure cells are coupled to an underlying surface and which is smaller in dimension relative to an overlying portion of the pressure cell.

  • 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.

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.

  • Publication number: 20150119772
    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.

The first pump assembly defines a first pneumatic passage configured for fluid communication with the pump unit. A second pump assembly includes a second pump unit and a second electrical contact. The second pump assembly defines a second pneumatic passage fluidly communicable with the second pump unit. The first pump assembly defines a receptacle into which the second pump assembly is slidingly receivable. The sliding reception of the second pump assembly into the first pump assembly establishes fluid communication between the first and second pneumatic passages and establishes electrical communication between the first and second electrical contacts.

  • 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.
