The invention discloses a multilayered Hydrotherapy Blanket, Hydrotherapy Mummy Bag, and Hydrotherapy Bag that has an outer layer, and when compressed with air or water, this can be wrapped around the body tightly, while the inner layer circulates high pressured hot or cold water around the body. Compressed air is injected into Hydrotherapy tubes that have nozzle holes that release the air mixed with hot or cold high-pressure water onto a thin layer of water-proof barrier that is touching the body, simulating a Jacuzzi Hydrotherapy effect, without the body getting wet. The hot or cold water can be pumped from the top of the Hydrotherapy Mummy Bag, Hydrotherapy Bag, Hydrotherapy Blanket and Hydrotherapy Bed, then the hot or cold water can be pumped in the opposite direction inside Hydrotherapy tubes, causing an inward-outward Hydrotherapy massage effect. One can lay inside a Hydrotherapy Mummy Bag to get a full body massage. The invention comprises moving magnets to create a moving magnetic field to travel over the body. It allows the magnetic fabric to be used to help disperse the magnetic field around the body. The claimed invention also allows a Transcutaneous Electrical Nerve Stimulation (TENS) device configured to be attached to the said Hydrotherapy Mummy Bag, Hydrotherapy Bag, Hydrotherapy Blanket and Hydrotherapy Bed to help stimulate the muscles and nerves. The claimed invention also allows the portable Hydrotherapy Machine to be transported in a small vehicle for home to home Dry-hydrotherapy. The claimed invention also allows the portable Hydrotherapy Machine to operate on at least 10 gallons of hot or cold water/contaminated water to provide a safe Dry-hydrotherapy massage to the arm, leg or back.

A hydraulically adjustable walker including a frame that includes a plurality of telescoping legs and a leg adjustment assembly that includes at least one valve and at least one tube that delivers hydraulic fluid into the legs and allows a user to control the length of each leg. The legs of the walker are hydraulically adjustable, so that the front legs may be shortened and the back legs extended, or two side legs shortened and the two opposing side legs extended, so as to allow the walker to be securely placed on two different steps.

A pulsed pressure control system includes a supply unit, a switching unit, a first path, a second path, a fluid receiving device, and a return path. The first path and the return path are different paths connected between the supply unit and the switching unit. The second path is connected between the switching unit and the fluid receiving device. During pressurization, the switching unit cuts off communication between the first and second paths to increase the volume of, and eventually pressurize, the fluid on the first path, and then the switching unit is switched on to allow communication between the first and second paths to instantaneously release the pressurized fluid to the fluid receiving device through the second path. During pressure release, the switching unit allows communication between the second and return paths to allow the fluid to flow back to the supply unit through the return path.

A compact liquid-outlet system comprising a liquid pump device, a liquid-inlet flow channel, and a liquid-outlet flow channel and an oral cleaning method. The liquid pump device comprises a liquid pump cavity, a piston slidably disposed in the liquid pump cavity, and a piston rod. The piston rod extends through the liquid pump cavity in a liquid-tight manner and is connected to the piston. The piston divides a pump chamber of the liquid pump cavity into a rod chamber and a rodless chamber. The piston comprises a liquid-outlet one-way valve allowing only liquid to flow from the rod chamber to the rodless chamber. The liquid-inlet flow channel communicates with the rod chamber through a liquid-inlet one-way valve. The liquid-outlet flow channel communicates with the rodless chamber. This system eliminates the need of extra space for installing the liquid-outlet one-way valve, resulting in a more compact structure.

An active backboard that can assist with adjusting a patient on the backboard to ensure that the backboard is correctly aligned for a compression mechanism of an upper portion of a mechanical cardiopulmonary resuscitation (CPR) device to perform compressions. The active backboard can also include multiple layers that can slide or move relative to each other to move the patient relative to the backboard. The active backboard can include roller bars, a wheel, and/or projections to assist with moving a patient relative to the backboard.

A backboard for a mechanical cardiopulmonary resuscitation (CPR) device having a first connector, a second connector, an elongated portion, and a position adjustment mechanism. The first connector is structured to couple to a first leg of the mechanical CPR device. The second connector structured to couple to a second leg of the mechanical CPR device. The elongated portion extends along an axis between the first connector and the second connector. The position adjustment mechanism is structured to adjust a patient position on the elongated portion in an adjustment direction that is perpendicular to the axis between the first connector and the second connector.

The invention discloses a self-lubricating massager. The self-lubricating massager comprises a massager body, and two ends of the massager body are designated as a massage section and a handheld section respectively; a vibrating motor is installed inside the massage section, an end face of the massager body is provided with a liquid outlet, and a mounting frame is arranged inside the handheld section; one end of the mounting frame is provided with a operational chamber, a pressing head is installed in the operational chamber, a side of the pressing head is provided with a limiting edge, and a spring is arranged between the limiting edge and the operational chamber.

An inflatable penile prosthesis can include, a reservoir, an inflatable member and a pump assembly. The pump assembly can include at least one valve comprising an entry portion, a middle portion, an exit portion, and exit tube interface, and a valve member. The exit portion can include a first landing portion including an interior portion, the interior portion of the first landing portion being semicircular about a longitudinal exit axis, the longitudinal exit axis extending through a center of the exit portion parallel to a direction that an exit tube interface extends from the exit portion, and a first channel portion adjacent to the first landing portion and including an interior portion, the interior portion of the first channel portion being farther from the longitudinal exit axis than the interior portion of the first landing portion.
