A fluid pulsating generator utilizes a repeating pulsating component in conjunction with one or more piezoelectric members to generate a piezoelectric affect which creates an electrical voltage. The fluid pulsating generator can be incorporated into a pulsating sprinkler device which produces a continuous pulsating motion which causes the piezoelectric members to deform to generate the piezoelectric effect that produces the electrical voltage.

Fluid pulsating generator

An irrigation device, such as a sprinkler, includes an electric generator for generating electricity. The sprinkler includes a nozzle which couples to a fluid conduit, a rotary deflector positioned downstream from the nozzle and within the atmosphere, an electric generator coupled to the rotary deflector, and a frame coupling the nozzle to the electric generator. The rotary deflector rotates about an axis as a fluid stream exiting the nozzle contacts and sprays from the rotary deflector. The rotary deflector and the rotor of the electric generator are coupled to a common axial shaft such that rotations of the rotary deflector translate to rotations of the rotor.

The thermal isolation apparatus for the protruding probe of a biomedical thermometer includes an insulative air gap and a heat sink disposed between the surface of the probe and the optical path through the probe. The heat sink surrounds the optical path, such as a waveguide, and acts to evenly distribute any heat along the entire length of the waveguide to avoid temperature variations. Additionally, the heat sink has sufficient mass for high heat capacity and may slow the progress of any heat from reaching or leaving the waveguide until after the measurement by the biomedical instrument has been completed. Disposed over the heat sink is a boot which forms the closed air space between the heat sink and the outer probe surface. The air gap combined with the heat sink provide relative thermal isolation of the optical path through the probe and provide relative thermal isolation of the target anatomy from the temperature of the probe.

A medical valve assembly comprises a valve body having a fluid passage therethrough, a valve member, and an urging means disposed within the fluid passage. The valve member is adapted to seal against a sealing surface of the fluid passage and the urging means is adapted to urge the valve member against the sealing surface. The medical valve can be used without a needle thereby eliminating risks associated with needle stick injuries. In applications where it is expedient to use a needle (such as prepackage medications) the medical valve accommodates the use of a needle to administer medication. The urging means is disclosed in a first embodiment wherein it is formed integral with the head portion of the valve member. In an alternative embodiment, the urging means is separate from the head portion of the valve member and is comprised of a metallic spring element.

The protective apparatus for a biomedical thermometer having a protruding probe containing a waveguide includes mounting a transparent window at the patient end of the waveguide to seal the waveguide from contamination while permitting infrared energy to pass. A protective sleeve protects and mounts the transparent window to the waveguide and material is provided along the entire probe-length of the waveguide to protect it. An outer boot is mounted over the transparent window and waveguide protection material to provide further protection and to supply a mounting and retaining surface for a protective probe cover. A disposable protective probe cover having a generally thin, flat, frame member with an aperture therethrough, is sized to fit over and be retained over the base of the probe by a friction interference fit. Extending across the aperture of the probe cover frame member is a material which stretches to generally conform to the shape of the probe when the tip of the probe is inserted through the aperture of the frame. A probe cover sensor is provided to indicate the existence of a protective probe cover.
