Abstract: A subcutaneous infusion set. The subcutaneous infusion set may include a base for providing an infusion path; a cannula connected to and extending away from the base; a connector removably attachable to the base; and a tubing affixed to the connector. The connector may be limitedly rotatable on the base when the connector is removably attached to the base. Also, a contiguous pass for passing fluids may be formed from the tubing to the cannula when the connector is removably attached to the base.

Abstract: An infusion set for subcutaneous delivery of an infusant. The infusion set may include a base removably attachable to an infusion site and a connector temporarily lockable to the base. The connector can engage the base in a plurality of orientations. The connector locks into the base after at least partial rotation of the connector about the base. The connector may include flexible arms which unlock the connector from the base. The base includes a cannula for insertion through the infusion site. The connector includes a tubing for passing the infusant. The infusant is subcutaneously passable from the tubing through the cannula when the connector is attached to the base. The infusion set may also include a hub removably attachable to the base that includes a needle that extends through the base and the cannula and a guard removably attachable to the base opposite the hub for surrounding the needle.

Abstract: The present invention provides for a breathing device comprising a reservoir bag, oxygen source, scrubber, and activation device. The oxygen source and an exit from the scrubber may be fluidly connected to the reservoir bag. The reservoir bag may be attached to a mouthpiece to provide inhalation air. Expired air may be exhaled through the mouthpiece and directed to an inlet for the scrubber. As a user breaths normally, expired air is scrubbed of undesired components, such as excess CO2. The scrubbed expired air is then mixed with generated oxygen, and delivered back to the user for inhalation. Additionally, the oxygen source and the scrubber may be replaced and/or replenished without interrupting or compromising a breathing cycle.

Abstract: Fluid delivery devices, systems and methods. The fluid delivery devices may be used to delivery fluid (e.g., insulin) to a user. The devices may have one or more inlets, and may be configured for use with an injection device, such as a syringe, and/or with a pump.

Abstract: An inline oiler cartridge assembly for a pneumatically powered instrument includes a housing, a first conduit and a second conduit. The housing includes a lower portion removably attached to an upper portion. The lower portion defines an inner cylindrical cavity and an outer cylindrical cavity. A source of oil is disposed in the inner cylindrical cavity. A dry fiber cellulose material is disposed in the outer cylindrical cavity. The first conduit has a first end for attachment to a source of pressurized air and a second end for attachment to a pneumatically powered instrument. The first conduit passes through a portion of the upper portion of the housing and defines a channel for transmission of the source of pressurized air. The channel is in fluid communication with the inner cylindrical cavity such that the source of pressurized air draws oil into an air stream for delivery to the pneumatically powered instrument.

Abstract: For use in a hospital or other medical facility, provided is a powered surgical instrument. The surgical instrument can be used by doctors and the like for the dissection of bone and tissue. The surgical instrument includes a disposable drive unit and a dissection tool. The drive unit is made of a moldable or non-machined material, such as plastic, which does not have to sustain repeated use and sterilization over an extended period of time.
