Abstract: A fluid delivery device is provided for delivering fluid to a target site such as an intervertebral disc during discography. The fluid delivery device includes pressure and volume sensors to determine the pressure and the volume of the fluid delivered to the intervertebral disc. The fluid delivery device is hand-held during use and includes a syringe assembly having a plunger with threads that enables controlled discharge of the fluid from the fluid delivery device by rotating the plunger in a housing of the fluid delivery device. The fluid delivery device includes a communication module to wirelessly transfer data to an external device outside of a sterile field, while the fluid delivery device is in the sterile field. The fluid delivery device may also include a physiological sensor to monitor involuntary pain responses based on changing physiological parameters such as increases in body temperature or blood pressure.

Abstract: A manifold assembly for use in a medical waste collection device to direct fluid into the medical waste collection device while filtering material from the fluid. The assembly includes a manifold housing having a bottom and a wall extending upwardly from the bottom about a first axis, with an outlet port disposed on the manifold housing. A support structure disposed on the bottom has a filter support surface and defines a plurality of open spaces between the filter support surface and the bottom. A manifold cap having a unitary skirt is connected to the manifold housing to define a chamber therebetween, and has an intake port disposed thereon to direct the fluid into the chamber. A filter is supported by the filter support surface to filter the material from the fluid, the periphery of the filter positioned between the skirt and the support structure to prevent fluid received in the chamber from bypassing the filter as the fluid moves from the chamber to the outlet port.

Abstract: A monomer handling unit for storing a ampoule of monomer and releasing the monomer from the ampoule when desired is provided. The monomer handling unit can be used to attach to an enclosed mixer and release a monomer component of the bone cement into the mixer to be mixed with a powder component of the bone cement. The monomer handling unit can also be used to release the liquid monomer into another mixer, such as one that is not enclosed.

The assembly includes a manifold housing having a bottom and a wall extending upwardly from the bottom about a first axis. A support structure is disposed on the bottom and has a filter support surface spaced from the bottom to define a plurality of open spaces between the filter support surface and the bottom. The support structure has a ring defining an outer surface and spaced from the wall. At least one filter is supported by the filter support surface to filter the material from the fluid, the filter having a perimeter. A manifold cap is connected to the manifold housing to define a chamber therebetween, and an intake port is disposed on the manifold cap to direct the fluid into the chamber. An outlet port is disposed on the manifold housing, and a skirt is unitary with the cap and has an inner surface.

Abstract: An air filtration system and a helmet for use in the air filtration system are disclosed and utilized to filter air between a head and body of a user and an external environment. The air filtration system and helmet include inner and outer shells that define an air flow channel for channeling air about the user. A fan module is mounted between the inner and outer shells and a scroll housing is mounted adjacent the fan module. The scroll housing includes an air inlet for drawing air into the air filtration system and helmet, and at least one air outlet to distribute air flow to the air flow channel. The helmet includes air exits at front and rear sections that are in fluid communication with the air flow channel and the air outlet or outlets. The air filtration system includes a gown operating as a filter for filtering the air.

Abstract: A manifold assembly (12) for a medical waste collection device (10) is provided. The manifold assembly (12) comprises a housing (14) and a cap (16) connected to the housing (14) by a snap-fit connection (18).
