This disclosure is directed to improved chair assemblies that can be integrated with various technologies, including heating, massaging technologies, cooling, and other technologies. Various portions of the chair assemblies include attachment structures that permit electronic assemblies to be attached and removed from the chair assemblies. The electronic assemblies can include electronics that facilitate heat therapy, massage therapy, and/or cooling therapy functions.

Segment 4 is coupled to segment 3 about axis 17 intersecting axis 16 at first point 22. Segment 4 is coupled to segment 7 about axis 18 intersecting first point 22. Segment 5 is coupled to segment 2 about axis 19 parallel to axis 16. Segment 5 is geared to segment 3. Segment 6 is coupled to segment 5 about axis 20 intersecting axis 19 at second point 23. Segment 6 is coupled to segment 7 along axis 21 intersecting second point 23. Segment 6 is geared to segment 4. Axis 15 of rotation of terminal segment 7 relative to segment 2 connects first point 22 and second point 23.

A lung gas exchange device includes a front housing, at least one strap configured to affix the front housing to an anterior neck of a user, a vibration device positioned within the front housing, a wear plate configured to transfer vibration from the vibration device to the anterior neck of the user, a power source configured to provide power to the vibration device, a power control mechanism configured to allow a user to turn on and off the vibration device; and a central processing unit board connected to the power control mechanism, the power source, and the vibration device.

The present invention provides a device with a pressure control system and methods for controlling the application of negative pressure to an external surface of an individual for creating and/or maintaining patency of the upper airway passage. The device is configured to fit under the chin of a subject at an external location corresponding approximately with the subject's internal soft tissue associated with the neck's anterior triangle. The pressure control system contains control module elements that may include circuit board elements, digital output barometer elements, sensor elements, processing elements and memory elements to optimize device function and safety of the device through regulation of the flow rate of the air pump.

A spinal treatment system includes a traction device, an exercise device adapted for imparting curvature to the lumbar or sacral spine of a user and for manipulating the spine and intervertebral discs with decompression force, and a cushion coupled to the traction device and configured to bear against one or both of a head of the user and the thoracic spine of the user. The exercise device includes a frame for placement on the floor. A pad or inflatable bladder is carried by the top surface of the frame. A body strap attachment portion encompasses the thoracic-sacral spinal vertebrae region of the user and secures the frame to the user. The cushion includes one or more pad sections or inflatable bladder sections.

A pressure-sensing type massage chair system includes pressure sensing units configured to detect movement of any one or more of at least user's hips, feet, back, hands, head, and combinations thereof, or a change in a user's center of gravity; a first command signal output unit configured to receive pressure signals from the pressure sensing unit and match the received pressure signals with pre-input first command matching information to output a first command signal corresponding to the first command matching information; and a control unit configured to receive the first command signal from the first command signal output unit and apply any one or more of at least a seat control signal, a footrest control signal, a backrest control signal, an armrest control signal, a headrest control signal, and combinations thereof.

A massage device which allows a user to easily and effectively self-administer a neck and/or shoulder massage. The device includes a first post, a second post, a first base, a second base, a crossbar, and a foam roller. The crossbar is connected in between the first post and the second post. Additionally, the foam roller is rotatably mounted onto the crossbar so that the crossbar supports the weight of the user's head and neck while the user performs a foam rolling operation. That is, the foam roller rotates about the crossbar while the user performs the foam rolling operation. The first base and the second base are attached to the first post and the second post and support the massaging device in an orientation that facilitates performing the foam rolling operation.

A cushion for decompressing the human spinal column comprises a body support surface, a first short flat bottom surface, a longer second flat bottom surface, wherein the first bottom surface and the second bottom surface intersect and are angled at a particular angle lying within the range of 120 degrees to 150 degrees, but preferably at 135 degrees. A cushion for decompressing the human spinal column comprise a body support surface, and a curved bottom surface wherein the curve of the bottom surface increases or decreases in radius from one end to the other. The curve of the bottom surface may have the shape of an incomplete portion of a two-dimensional spiral.

A method of assisting a caregiver in delivering patient therapy includes providing prompts at a user interface, wherein the therapy includes steps in a protocol, at least one of which is an instruction for the caregiver to call the ERC by actuating the input device, initiating a call to an emergency response center (ERC) in response to actuation of an input device of a medical device, detecting, by one or more sensors, whether one or more steps of the protocol have been completed in response to the prompts, wherein at least one of the sensors is a sensor other than a therapy electrode, selecting one or more prompts based at least in part on whether the one or more steps in the series has been performed, and controlling the user interface to provide the selected one or more prompts as visible and/or audible prompts.

Technologies and implementations for wearable healthcare devices are generally disclosed. An example method performed by a wrist-wearable device includes: detecting, by a sensor, a physiological parameter of a user; determining, by a processor based on the physiological parameter, that the user is experiencing atrial fibrillation (AF); outputting, by a display, a visual signal indicating that the user is experiencing the AF; and transmitting, by a transceiver to a first external computing device, a first wireless signal indicating that the user experienced the AF.
