Use of ultrasound beams to unlock the perception of mid-air tactile stimuli on hairy skin by using acoustic streaming is described. Such acoustic streaming is directional, more focused than fan and air-puff devices, doesn't require the use of cumbersome attachments, fast since it can be generated at a distance with the speed of sound, and can be used in a complementary fashion with vibrotactile mid-air stimulation deriving from the same hardware. Further proposed is a way to modulate the thermal perception of the mid-air tactile stimuli without the need for a thermal source or wearables. The effect of acoustic streaming and its thermal modulation may be combined for the accurate elicitation of affective touch sensations.

Disclosed is a massage device according to one embodiment of the present disclosure. The massage device comprises: a body structure for forming an area to accommodate at least one portion of the body of a user and defining the outer shape of the massage device; a massage module for supplying a massage function to the at least one portion of the body of the user accommodated in the area in the body structure; an input unit for receiving an input of an arbitrary form from the user of the massage device; a display for displaying massage mode screen information which can be selected by the user of the massage device; and a control unit for controlling one more operations of the massage device on the basis of at least a part of the input of an arbitrary form received by the input unit. The massage mode screen information may include: an automatic mode graphic object linked to a function of performing an automatic mode consisting of a predetermined massage pattern and massage time; a manual mode graphic object linked to a function of performing a manual mode to allow a user of the massage device to configure a massage pattern and massage time; and a massage option mode graphic object linked to a function enabling selection of a massage option mode consisting of an additional function that provides convenience to a user of the massage device in addition to a massage operation that applies pressure to at least a part of the body of the user of the massage device.

A massage device for massaging by means of pressure waves includes a housing having a handle segment and a massage segment and at least one chamber comprising an opening leading outward in the massage segment. The chamber includes an end wall segment, a first circumferential wall segment, and a second circumferential wall segment, the first circumferential wall segment being disposed between the end wall segment and the second circumferential wall segment, and the second circumferential wall segment defining the opening with the end wall segment being at least partially displaceable. The massage device further includes a drive device for inducing a predetermined vibration in the end wall segment, with the first circumferential wall segment being substantially rigid and the second circumferential wall segment being substantially flexible.

A treatment device for removing heat from subcutaneous lipid-rich cells of a subject having an actuator that provides mechanical energy to the tissue. The mechanical energy provided may include a vibratory component that can range between low and ultra-high frequencies, and such energy may include various combinations of two or more frequencies tailored to produce the desired effect on the subcutaneous tissue. Disruption of adipose tissue cooled by an external treatment device may be enhanced by applying mechanical energy to cooled tissue. Furthermore, such mechanical energy may impart a vibratory effect, a massage effect, a pulsatile effect, or combinations thereof on the tissue.

A negative-pressure cup structure includes a cup and a vibration generating mechanism. The cup has a chamber. Two ends of the cup are separately formed with an opening end and a closed end. The closed end is provided with a negative-pressure suction hole and an electric connection hole communicating with the chamber. A bar is extended from the closed end and located in the chamber. The vibration generating mechanism includes a box, a vibration member disposed in the box and a power connector electrically connected to the vibration member. The vibration generating mechanism is fixed in the chamber of the cup in a manner of the box and the bar being connected and the power connector being inserted to the electric connection hole. Therefore, the users may obtain a better vibrational sense.

A massage apparatus and system are herein disclosed. The massage apparatus is embedded in a sole or insole of a shoe and includes a controller, massage pads, and a battery. The controller communicates with a remote controller to selectively activate the massage pads. The present invention allows for customizable massaging at reflexology regions of a user's foot.

A high frequency chest wall oscillation therapy system includes an air pulse generator. The air pulse generator includes control circuitry and a fluid chamber carrying a fluid. A motor is configured to generate compression and expansion of the fluid in the fluid chamber to generate pressurized fluid. A pressure sensor detects a pressure of the pressurized fluid in the fluid chamber. A garment includes at least one fluid bladder defining a pressurizable chamber adapted to receive the pressurized fluid from the fluid chamber to provide a force of high frequency pressure oscillation to a patient's chest wall.

The non-invasive pulsatile circulatory support device intended to promote circulation of a blood volume in at least a part (Z) of a subject's body, the device including a flexible structure, arranged so as to be applied on at least the part of the subject's body, including a series of paired adjacent pouches extending along one another; and means for generating a physiologically synchronised pulsation fluidically connected to the flexible structure in a leak-tight manner and arranged so as to create pulsation waves in the series of pouches between the inner and outer layers, one of the paired adjacent pouches at least partially covering the other of the paired adjacent pouches (scaled structure).

The pneumatic therapy apparatus and method with overlapped compression include a wrap and a controller. The wrap includes an outer wrap and an inner air bladder set; the controller can be fixedly connected to, detachably connected to, or separately connected to the outer wrap; the inner air bladder set includes one or more than one set of a first air bladder and a second air bladder that are overlapped; the controller contains an inflating motor and an integrated control board that are electrically connected. The inflating motor that is controlled by the integrated control board inflates the second air bladder first and then the first air bladder to achieve the overlapped compression between the second air bladder and the first air bladder. Therefore, the user can use the pneumatic therapy apparatus and method with overlapped compression to promote blood flow, treat lymphedema, prevent deep vein thrombosis and other diseases, and improve user experience in the treatment areas.

Medical pressure therapy can be used on a patient having undergone treatment to reopen an arterial obstruction, such as a stenosis or occlusion. The medical pressure therapy can establish and maintain persistently good distal runoff. The can help ensure the patency of the region having undergone the treatment procedure. In some examples, the technique involves enclosing at least a portion of a limb of a patient on which an obstruction treatment procedure has been performed in an enclosure such that the portion of the limb is sealed from external conditions. The technique further involves alternately applying a negative pressure within the enclosure and releasing the negative pressure from within the enclosure, thereby increasing a volume and velocity of blood flowing past a region of the blood vessel previously-obstructed and thereby increasing distal runoff.
