Disclosed is a method of suppressing vibration of a mechanical device imposing upon at least one human hand holding the mechanical device. The method generally includes steps of preparing and assembling a fixing pin, an upper metal pad, an upper suppressing pad, a lower suppressing pad, and a lower metal pad to form a vibration-suppressing unit, and employing a fixing rack in collocation with an actuating part to fix the vibration-suppressing unit onto a massage body. In particular, the two adjacent upper vibration-suppressing washers are specifically designed to have different elasticity modulus, and the two spaced away and not adjacent upper vibration-suppressing washers have the same elasticity modulus, thereby suppressing and alleviating the vibration level to hand due to counterforce. Thus, the method achieves the effect of suppressing vibration, greatly alleviates counterforce imposing upon hand, and effectively avoiding fatigue, sore, chronical inflammation, or physical hurt.

A percussive massage gun includes a handle; a battery assembly including an upper shell, a lever, a tab formed with the lever, two first biasing members, a battery, a second biasing member biased between the tab and the battery, and a lower shell; and a connection member formed with the handle and releasably secured to the battery assembly. The battery is releasably fastened in the upper and lower shells. The upper shell includes a slot with the lever disposed through, and a through hole. The lever includes two pegs. The first biasing members are put on the pegs to push the lever through the through hole. The lower shell includes two bossed holes for complementarily receiving the pegs.

A massager providing massaging frequencies in the range of 75 to 250 hertz, and preferably 100 to 200 Hertz is provided. The massager includes a motor for generating rotational motion, an applicator head having multiple treatment surfaces, and a shaft attached to the motor and applicator head for translating the rotational motion to the applicator head. The massager also includes a restraining mechanism attached to the applicator head. The restraining mechanism is configured to prevent the applicator head from rotating, thereby generating a circular motion in each of the treatment surface. The circular motion has diameters in a range of 0.1 mm to 5 mm and a preferred frequency of 100-200 completed circular movements per second.

A wearable thorax percussion device for dislodging mucous buildup in the airways of a human patient, the device comprising frame elements and electromechanical actuators retained by the frame elements to intermittently percuss the thorax, and an electronic controller and power source for generating and modulating an electrical signal to energize the actuator. The frame elements may be interconnected by a garment, or fasteners and elastic or adjustable strapping.

A patient support for supporting a patient includes an inflatable mattress defining a support surface and a pneumatic system for inflating the inflatable mattress. The pneumatic system includes a pressurized reservoir for holding pressurized air and selectively releases pressurized air from the reservoir to the mattress.

A percussive massage device that includes a housing, an electrical source, a motor positioned in the housing, a switch for activating the motor, and a push rod assembly operatively connected to the motor and configured to reciprocate in response to activation of the motor. The housing includes first, second and third handle portions that cooperate to define a handle opening, wherein the first handle portion defines a first axis, the second handle portion defines a second axis and the third handle portion defines a third axis, and wherein the first, second and third axes cooperate to form a triangle.

A lip plumping device includes a positive pressure device having a striking rod and striking head attached on the an end of the striking rod; a force-generating element to propel the striking head with energy which upon impacting on a target spot on a lip or in an area around the lip increases blood flood to the target spot on the lip or in the area around the lip which produces a lip plumping effect; and a button that controls the force-generating element. The target spot and a striking force of the positive pressure device is controlled by instructions from a computing device.

A skin cleanser includes a surface, such as a silicone surface, with at least one textured portion for transmitting vibrational tapping to the skin. The skin cleanser includes at least one oscillating motor fist generating the tapping motion to the skin. The textured portion includes touch-points or a wave that transmit the tapping motion to skin in contact with the textured portions. The touch-points may include thicker and thinner formations of the touch-points to provide firmer or stiller vibrations to the skin. The touch-points are within about 0.5 to 2.5 nun in diameter. One configuration includes multiple oscillating motors configured to provide different vibration frequencies at around 50-300 Hertz and operable simultaneously.

One configuration includes multiple oscillating motors configured to provide different vibration frequencies at around 50-300 Hertz and operable simultaneously.

Method and apparatus for providing percussive ventilation therapy to a patient airway preferably includes at least one driver unit configured to provide pressurized, non-pulsate gas. At least one patient interface device preferably has structure configured to (i) receive the pressurized, non-pulsate gas from the at least one driver unit and transform it into a pulsed and pressurized gas, and (ii) supply at least one sub tidal volume of pulsed and pressurized gas to a patient through a patient connection orifice. At least one flexible tube is preferably configured to provide pressurized, non-pulsate gas from the at least one driver unit to the at least one patient interface device. Preferably, at least one portion of the patient interface device is disposable, and another portion may be reusable. Preferably, the invention uses Adaptive Dynamic Subtidal Ventilation technology.
