This invention relates to an improved vial transfer assembly or vial transferset which may be attached to a vial under sterile conditions and used to transfer fluid to or from a conventional vial. The transferset includes a tubular transfer member which is sealingly supported on the rim portion of a vial stopper, a piercing member having a piercing end reciprocally supported by an internal surface of the transfer member, a cap enclosing the tubular transfer member and a collar preferably formed of a malleable material which secures the assembly on the stopper, which is crimped beneath the vial rim. The piercing member has a generally longitudinal external channel which, upon piercing the planar portion of the stopper, establishes fluid communication with the vial through the tubular transfer member. The distal end of the tubular transfer member includes a Luer lock for establishing fluid communication to a syringe, IV set or the like. An annular lip on the proximate end of the tubular transfer member stretches and prestresses the central portion of the planar stopper rim and the piercing member is supported in the transferset such that the piercing end deforms the prestressed stopper rim portion.

Vial transferset and method

According to one broad aspect of one embodiment of the present invention, disclosed herein is a hand held oral irrigation device having a tip for dispensing fluids. In one example, an oral irrigation device includes a body portion, and a reservoir for storing fluids, wherein the body and/or the reservoir define a first major diameter at a lower end of the oral irrigation device, and define a second major diameter at an upper end of the oral irrigation device, the first major diameter being larger than the second major diameter. In this example, by providing such a geometry for the device, a user can grasp the device with one hand about the second major diameter during use. In another example, the body includes a pump for pumping fluids from the reservoir to the tip, wherein the pump includes an inlet valve and an outlet valve, the inlet valve including a reed valve made of flexible fabric material. The outlet valve may also include a reed valve made of flexible fabric material.

Hand held oral irrigator

A powered irrigator for use in rinsing nasal cavities has a main body including a handle and a fluid reservoir detachably coupled to one another, an outlet nozzle extending from a top end of the handle, a pump mechanism operably coupled to a power source, and a switch operably coupled to the power source for turning the pump mechanism on and off. When the switch turns on the pump mechanism, fluid flows from the fluid reservoir into a first fluid coupling between the reservoir and the pump mechanism and into a second fluid coupling between the pump mechanism to the outlet nozzle. The top of the handle can be angled relative to a longitudinal axis of the main body. The nozzle is removable from the top end and has a self-sealing structure to provide an enhanced fit within a user's nostril.

Powered irrigator for sinus cavity rinse

An apparatus for providing a pressurized water stream for cleaning gums and teeth. The embodiment includes a base unit defining a cavity. The cavity contains a pump, which may move pressurized water from a reservoir to a tip in fluid communication with the pump. A flow control knob may be turned to selectively adjust the water pressure supplied by the tip between a minimum and a maximum value. The reservoir may be removed from the base unit so that it may be filled with the fluid. The reservoir may support a container for storing tips or other items. Fluid may flow from the reservoir and ultimately into the tip to provide oral irrigation and/or cleaning of the teeth, gums, and tongue.

Water jet unit and handle

An oral irrigator includes a base having a pump mechanism, a reservoir housed within the base and fluidically connected with the pump mechanism. A handle (908) with a jet tip (910) is connected with an outlet from the pump mechanism to receive a pressurized fluid stream from the reservoir to direct a fluid at a surface inside an oral cavity. The oral irrigator also includes a radiant energy source (916) and delivery system (922) for directing radiant energy at a surface inside an oral cavity.
