Abstract: A portable motorized fluid sprayer device is described, having a fluid tank and a pump manifold configured to pump fluid from the tank and into a connected fluid conveying structure (e.g., a hose, wand, nozzle, handle and/or similar structures). The manifold may include an electric motor, a gear pump, a controller, and a battery. Additionally, the fluid sprayer device may allow for spraying fluid with consistent pressure, recirculation of fluid within the tank, a gear pump for spraying or suctioning fluid from the fluid conveying structure, a safety lever, the ability to separate the pump manifold from the fluid tank, and other features.

Abstract: A non-invasive and permeable RF diagnosis and treatment equipment and its catheter are provided. The catheter which comprises a tube body, a RF electrode array and a flexible protecting net has a retractable cavity, and the RF electrode array is attached to an outer surface of the retractable cavity; the flexible protecting net surrounding outside of the RF electrode array has a connector connected with the tube body and multiple holes. The retractable cavity has a smaller volume contraction state and a larger volume expansion state. Using the catheter, when inserting or pulling out the catheter, the RF electrode array will not contact the inner wall of the organ, but the flexible protecting net contacts the inner wall of the organ. In this way, the scratch of the inner wall of the organ caused by the RF electrode array can be minimized or even avoided through the flexible protecting net.

Abstract: A therapeutic apparatus is disclosed, comprising a signal generator configured for generating a therapeutic signal, a treatment head, multiple sets of electrodes arranged on the treatment head, a switch circuit connected between the signal generator and multiple sets of electrodes, and a control unit connected with the switch circuit, and by the control unit controlling on-off of the switch circuit, the signal generator is controlled to be connected with at least one set of electrodes to output the therapeutic signal. Through the therapeutic apparatus, energy can be controlled to be output only to the local area, so as it can be attached to the surface of the skin in the narrow space and treat the skin in the narrow space. When only part of the electrodes are connected with the signal generator, the output power of the signal generator can be concentrated on outputting the therapeutic signal.
