Systems and methods for monitoring posture of a user wearing an exosuit are discussed herein. Exosuits worn by users can monitor several movement factors that characterize the user's movements and posture. The user's posture is identified and analyzed, and feedback is provided to the user based on the analyzed posture.

The present invention discloses a pressure generator and a massager. The pressure generator includes a shell defining a first opening and a receiving space, a movable member extending into the receiving space and a drive device driving the movable member to reciprocally move within the receiving space. A gap is defined between the movable member and the inner wall of the shell.

The present application discloses a muscle massage device including a shell, a high-frequency hitting unit disposed on the shell and an electric pulse unit disposed on the shell. Due to the cooperation of the electric pulse unit and the high-frequency hitting unit of the muscle massage device disclosed by the present application, EMS electric pulse massage and high-frequency vibration massage are effectively combined; the shell is disposed to be of a bilateral symmetry structure which is in smooth transition, so that multi-angle free massage is effectively realized; and a flexible buffer part is disposed between a support fixing part and a motor fixing seat, so that power stability is realized, meanwhile, noise is effectively reduced, and the sense of use is improved.

A device applies therapeutic treatment to a subject. The therapeutic treatment includes any two modalities applied simultaneously, the modalities selected from compression, heat, vibration, and massage. The device includes a main body; hinges coupled to the main body on each side of the main body; and respective plates connected to the hinges, wherein the respective plates contact opposing surfaces of a body.

A training apparatus is disclosed, comprising: a top structure, a bottom structure, and a traction structure disposed between the top structure and the bottom structure, and wherein the traction structure is configured to be retractable along an axial direction of the top or bottom structure to achieve relative movement between the top structure and the bottom structure.

Embodiments provide devices, systems and methods for preventing deep vein (DV) thrombosis (DVT). One embodiment provides a DVT prevention device including a cuff that fits over a patient's knee, an applanator coupled to an inside cuff surface, an expandable member (EM) coupled to the applanator, a pressure source fluidically coupled to the EM and a controller for controlling EM inflation. When the EM is inflated, it applies a force to the applanator which is transmitted to the knee back surface causing a popliteal vein (PV) under the cuff to be compressed so as to increase backpressure behind the compressed PV and subsequently increase the velocity of blood flow in the leg DV's when the EM is deflated. The EM can be inflated in a cycle including pulsed inflation, inflation hold and relaxation. The cycles can be repeated and adjusted to achieve a desired increase of blood flow/velocity in leg DV's.

A pneumatic system includes a passage to discharge compressed air and a sound attenuator including a first chamber in fluid communication with the passage and defined by a first wall through which the passage opens into the first chamber, a first surface of a second wall spaced from and opposite the first wall, and a sidewall extending between the first and second walls. The first chamber has a volume and includes a first opening in the sidewall. A second chamber is in fluid communication with the first opening and partially surrounds the first chamber. The second chamber is partially defined by a second surface of the second wall opposite the first surface and by the sidewall, and the second chamber has a volume and includes a second opening to exhaust air from the second chamber. The volume of the first chamber is less than that of the second chamber.

A pneumatic system includes a fluidic switching module having an air passage and a vent in fluid communication with the air passage. The pneumatic system also includes a sound attenuator coupled to the fluidic switching module, the sound attenuator having a first chamber in fluid communication with the vent, a first orifice in fluid communication with the vent via the first chamber, a second chamber in fluid communication with the first chamber via the first orifice, and a second orifice in fluid communication with the first orifice via the second chamber.

Ultra-low frequency (ULF) tactile stimuli, generated by an electro-mechanical actuator, have a spectrum of biological effects. These frequencies are herewith defined as 2 Hz or lower and may comprise stimulus frequencies as low as 0.1 Hz, or one cycle per ten seconds. The ULF generator can be paired with at least one sensor that is configured to monitor a physiological property of the user. A controller is in communication with the at least one electro-mechanical actuator and the at least one sensor and is configured to control operation of the at least one electro-mechanical actuator, in at least a first operating mode, based on measurements of the at least one sensor.

An air pressure massager includes at least one pressure field generating device. The pressure field generating device includes a chamber with at least one first opening, a connecting rod member connected to one end of the chamber, an eccentric member connected to the connecting rod member, a driving unit connected with the eccentric member, a control device configured to activate the drive unit, and an accessory. The first opening is configured to be placed on a portion of a human body. The driving unit drives the eccentric member to move to drive the connecting rod member to move, such that a volume of the chamber is changed to generate a pressure field for stimulating the human body. The pressure field generated in the chamber directly towards the portion of the human body. The pressure field is adjusted by a positive pressure mode and/or a negative pressure mode.
