Techniques and devices for extending a piston and/or compression unit, for example connected to a medical device such as a mechanical CPR device, to accommodate different sized patients, are described herein. In some cases, a piston of a mechanical CPR device may include an inner piston at least partially slidable into an external piston sleeve. In one aspect, some aspects, the piston includes sleeves which can move relative to each other to extend the piston. In additional aspects, the compression mechanism may also extend downward toward the patient. In all aspects, the change in length of the piston may be detected and used to modify movement of the piston, for example to more safely perform mechanical CPR.

A spine board is provided having a skull tong anchor assembly slidably attached to the spine board where a push rod mechanism is used to apply traction force on the skull tong anchor assembly. The push rod mechanism includes a strain gauge device so that the traction force can be selected and monitored. The spine board can also include a mattress that can be attached to the spine board where the mattress includes integrated shoulder straps that can be partially detached therefrom to secure a patient to the spine board.

A vertical rhythm machine includes a base, a driving mechanism, an eccentric mechanism, two transmitting mechanisms and a housing. The eccentric mechanism is assembled with the driving mechanism. Each of the transmitting mechanisms includes a transmitting plate, a linking shaft, a first transmitting assembly and a second transmitting assembly. The transmitting plate is arranged on the eccentric mechanism. The linking shaft passes through the transmitting plate. The first transmitting assembly and the second transmitting assembly are pivoted on the linking shaft. The housing is disposed on the first transmitting assembly and the second transmitting assembly. The eccentric mechanism is driven by the driving mechanism to drive the transmitting plate. The transmitting plate drives the linking shaft to move reciprocally. The first transmitting assembly and the second transmitting assembly are linked with the linking shaft to drive the housing to move reciprocally.

A rabbit vibrator comprising two arms connected to an ergonomic handle. The rabbit vibrator consists of an internal arm that stimulates the vagina and external arm that stimulates the clitoris, both integrated into a triangular handle. The body of the product is super flexible, made of compliant silicone for the user's comfort and conformation to their anatomy.

The present disclosure relates to a massage device capable of repositioning when a power failure occurs, comprising: an energy storage unit that stores electrical energy supplied from a power supply unit; an input unit that receives an input from a user when the electric energy supply is cut off from the power supply unit; a back angle actuator that receives, on the basis of the input unit, electric energy from the energy storage unit and moves a body massage unit such that the massage device is in an initial state; and a leg angle actuator that receives, on the basis of the input unit, electric energy from the energy storage unit and moves a leg massage unit such that the massage device is in an initial state.

The scratch panel is a wall-mounting panel to relieve itching in particularly difficult to reach locations, such as the back. It utilizes artificial turf and sand paper like textured surfaces upon which the body may be scratched. Since the panel is wall-mounted, no hands are necessary to relieve bothersome itches. The panel holds adjustable rollers that stretch the artificial turf and allow recycling of the surface. The adjustable rollers allow the user to use different parts of the turf and replace said turf when necessary. The disclosed device includes a scrollable abrasive material stretched across a first scroll and a second scroll wherein the scrolls each lock to fix the scrollable abrasive material in a fixed relation thereto. A holder receives the scrolls in a rotating relation and provides a grip for a user and defines mounting holes to a wall or a piece of furniture.

A shoulder joint tracking apparatus includes a gravity compensation spring that compensates for a vertical movement of a shoulder joint of a trainee, a weight of an arm, and gravity to a weight of a rehabilitation exercise device attached to the arm, and a shoulder joint tracking device that is provided at one side of the shoulder rehabilitation apparatus, is connected to the gravity compensation spring, and applies a damping force corresponding to a force applied by the trainee, in a direction opposite to a direction in which the force is applied, to control a vertical movement of the shoulder rehabilitation apparatus.

A device for spine rehabilitation comprising a support frame, immovable crossbars, movable crossbars, and a holder and systems of actuators supporting a patient's head, shoulders, hip, knees, and feet, characterised in that it is equipped with linear actuators (8) mounted to the holder (7) supporting the patient's head and shoulders, whereby the holder (7) has a driving mechanism (9) situated horizontally and mounted to an immovable crossbar (6) of the support frame (1) and in its lower part is rotationally mounted, at the rotation point (10) of the holder, to the immovable crossbar (6). A method for spine rehabilitation using the device for lateral deviation of the patient's torso, whereby the patient's body situated horizontally, face up, is lifted on eight sling hangers taking hold of his/her head and his/her back in the points of shoulder girdle and pelvis girdle.

A hand-held low-noise shock-absorbing electric massager includes a lower shell, an upper shell, and a moving shaft rod. A right end of the moving shaft rod is provided with a massage head. The hand-held low-noise shock-absorbing electric massager further includes a transmission module bracket. An outer side wall of the moving shaft rod is coaxially provided with a shaft sleeve lubricating member. The driving part is arranged at a left end of the transmission module bracket. Two sides of the transmission module bracket are each provided with a first shock-absorbing member. The moving shaft rod is installed on the shell through the transmission module bracket. The transmission module bracket is integrated, which can ensure consistency and stability of the moving shaft rod in high-speed linear motion, that is, vibration between the moving shaft rod and the transmission module bracket is reduced during motion, and noise is also reduced.

A portable cardiopulmonary resuscitation (CPR) system includes a first module hub housing, an inflation actuated soft gripper configured to receive an inflation gas, and in response, to change form to a deployed grip state that accommodates and grips a human torso. Features of the portable CPR system include modularity for in-the-field reconfigurability, in which a second module hub housing attaches to the first module hub housing, carrying a CPR pressure applicator configured to receive an actuator power and a CPR control signal causing, concurrent with the deployed grip state, cyclic extension and retraction of the CPR pressure applicator along an axis aligned with a sternum of the human torso.
