Abstract: A portable air pre-treating device for medical treatment has an outer bottle with an air-heater, an inner water bag, a diverging connector, a dual tube, a venturi tube and an optional mask. The inner water bag is mounted inside the outer bottle. The diverging connector is mounted on the outer bottle to hold the inner water bag. The dual tube is attached to the diverging connector to communicate with the inner water bag and then extend to the optional mask. The venturi tube has an hourglass-shaped channel and is mounted inside the dual tube to make the air easily pick up moisture from a capillary ball when the air passes through hourglass-shaped channel. Thereby, the air is pre-heated in the outer bottle and then moisturized in the dual tube to be a suitable condition for breathing.

Abstract: A respiration nozzle has a hollow body with a front and a rear, at least one outlet made of a resilient membrane, and two inflatable nasal tubes. The at least one outlet is formed on the front of the hollow body and has a cross-shaped slit valve defined in the membrane to temporarily open and release air from the respiration nozzle. The two inflatable nasal tubes are formed on the rear of the hollow body and are enabled to inflate when air is pumped into the respiration nozzle. Therefore, air pressure inside the respiration nozzle is kept at a positive pressure to minimize consumption of electricity when pumping the air. Meanwhile, the inflatable nasal tubes gently and evenly match the nasal cavities without causing any uncomfortable feeling to the wearer.

Abstract: An adjustable air conditioning and regulation apparatus for human respiratory system includes an air treatment assembly and a host controlling assembly. The air treatment assembly has an air filter, a humidity control, a heating device for temperature control and a pressure control. The air filter removes the particles and smells from the air. The clean air is regulated by the controls that maintain the clean air at a desired level of temperature, pressure and humidity. The apparatus provides clean, fresh and comfortable air for the patients with compromised respiratory system.

Abstract: A nurse robot has a stand and a supporting assembly. The supporting assembly is mounted on the stand and has a seat, a backrest, a leg plate, step plate, a first driving device and a second driving device. The seat is attached to the stand. The backrest is pivotally attached to one end of the seat plate. The leg plate is pivotally attached to the other end of the seat. The step plate is pivotally attached to the other end of the leg plate. The first driving device is attached to the seat to drive the backrest and the leg plate to pivotally rotate relative to the seat. The second driving device is attached to the leg plate to drive the step plate to pivotally rotate relative to the leg plate. Accordingly, a patient can conveniently move to any desired place without any other person's help.

Abstract: A water powered pumping system includes a leverage connected to a water source and moving upward and downward by using a water weight to produce a lever movement, a hydraulic pump pushed by the leverage to move reciprocally, and a water pump pushed by the hydraulic pump to perform a water drawing movement for drawing the water contained in a water source and conveying the water into a water storage tower.

Abstract: A natural power water pumping system capable of conveying a water flow to any height includes a leverage capable of supporting a water source and moving upward and downward by using a water weight to produce a lever movement, a hydraulic pump pushed by the leverage to move reciprocally, and a water pump pushed by the hydraulic pump to perform a water drawing movement for drawing the water contained in a water source and conveying the water into a water storage tower located at any height.

Abstract: A water pumping system includes a solar collector assembly having a plurality of solar collectors containing a heat transfer medium therein. A circulating tube is mounted in an insulated housing and communicates with the solar collectors for conveying the heat transfer medium to circulate therethrough such that water received in the insulated housing is evaporated to vapor by means of the heat transfer medium. A receiver is provided for receiving the vapor created in the insulated housing therein. A pressure chamber communicates with the water source for conveying water contained in the water source into the pressure chamber. A conduit communicates between the pressure chamber and the receiver for conveying the vapor received in the receiver into the pressure chamber so as to force water contained in the pressure chamber into the container via a conveying tube.

Abstract: A parking tower includes a plurality of layers, an elevator device mounted in a frame structure and movable up and down to each of the plurality of layers by means of a lifting device, at least one conveying device slidably mounted on each of the plurality of layers and movable horizontally in a parking zone of associated layer for supporting a car thereon, at least one pair of pinions mounted in each of the plurality of layers and each meshing with a corresponding rack of the conveying device, at least one pair of transmission devices mounted on each of the layers and each actuated by a driving device for rotating a corresponding one of the pinions, at least one pair of manipulating devices each detachably connecting between a corresponding one of the transmission devices and associated pinion.

Abstract: An energy regenerative apparatus for a water hammer type pump includes a water hammer type pump and an engergy regenerative apparatus. The water hammer type pump includes a reservoir which is connected to a pump body by a pipe. A pressure tank is fixed on top of the pump body. A piston rod with a piston head is slidably provided in the pump body. A water passage between the pump body and the pressure tank is controllable by the piston head so as to control a flow of water from the pump body to the pressure tank. A flat valve is disposed between an outlet pipe and the pressure tank so as to prevent any reverse flow of water from the outlet pipe into the tank. A water gate valve is provided for controlling a water passage of the pump body.
