| 417479000 | Distributor formed from integral portion of flexible wall pumping member | 6 |
| 20090087328 | PULSE GENERATING DEVICE - A pulse generator has a rigid body with a resilient flow conduit passing therethrough. Pressure is periodically selectively applied to the interior of the body which compresses the flow conduit and induces a pressure pulse in the fluid contained therein. The pulse generator may be used as a stand alone pump or in concert with a continuous flow pump to provide a pulsatile output flow having customized waveform characteristics. The pulse generator may be used with medical equipment such as a heart-lung bypass machine or a dialysis machine. | 04-02-2009 |
| 20110116956 | HAND PUMP FOR PUMPING FLUID - A hand operable pump device for pumping fluids includes a hollow body and an oval piston. The hollow body includes an inlet port and an outlet port. The inlet port is provided with a one-way valve permitting fluid flow into the pump. The outlet port is provided with a one-way valve permitting fluid flow out of the pump. The oval piston is designed to be pressed inwardly from an initial position by the hand, decreasing the volume of an oval chamber with a corresponding oval cross-section. The chamber is located within the pump and is fluidically connected with the inlet and outlet ports. The oval piston is further designed to return to the initial position when released, increasing the volume of the chamber. | 05-19-2011 |
| 20110293453 | BALL VALVE DEVICE AND METHOD FOR FORMING A BALL RETAINER IN A CHECK VALVE - The ball valve device comprises a tubular body in metal material, having a cylindrical wall conformed with cup-shaped internal protrusions to retain a ball shaped valving member, preventing the same valving member to be entrained by a fluid flowing through the valve device. The internal protrusions are performed by radially deforming inwards the cylindrical wall of the tubular body at one or more angularly spaced apart deformable areas. The tubular body provided with the ball retaining protrusions is suitable for any valve device, such as ball check valves pumping units for and/or ducts. | 12-01-2011 |
| 20130039789 | VACUUM, PRESSURE OR LIQUID PUMP - It comprises driving means ( | 02-14-2013 |
| 20130058818 | FLUID CONTROL DEVICE - A fluid control device includes a vibrating plate unit, a driver, and a flexible plate. The vibrating plate unit includes a vibrating plate with first and second main surfaces, a frame plate surrounding the vibrating plate, and a link portion linking the vibrating plate and the frame plate and elastically supporting the vibrating plate against the frame plate. The driver is on the first main surface of the vibrating plate, and vibrates the vibrating plate. The flexible plate having a hole faces the second main surface of the vibrating plate, being fixed to the frame plate. At least a portion of the vibrating plate and the link portion are thinner than the thickness of the frame plate so that the surface of the portion of the vibrating plate and the link portion, on the side of the flexible plate, can separate from the flexible plate. | 03-07-2013 |
| 20130058819 | FLUID CONTROL DEVICE - A fluid control device includes a vibrating plate including a first main surface and a second main surface, a driver that is provided on the first main surface of the vibrating plate and vibrates the vibrating plate, and a plate that is provided on the second main surface of the vibrating plate and has a hole provided thereon. At least one of either the vibrating plate or the plate is positioned between the hole and a region of the vibrating plate facing the hole, and includes a projection projecting in a direction intermediate between the hole and the region of the vibrating plate facing the hole. | 03-07-2013 |
