An emergency eyewash station is disclosed. The emergency eyewash station includes a reservoir containing an eyewash fluid and a mechanism for dispensing the eyewash fluid from the reservoir to wash an injured person's eyes. An expandable container is configured and arranged to collect used eyewash fluid after the eyewash fluid has been dispensed to wash the injured person's eyes. The station can be further enhanced by equipping the expandable container with a pair of straps configured to compress the reservoir thereby providing a gravity assist to dispensing eyewash fluid.

A retrofit kit for an emergency eyewash station and method of retrofitting a plumbed emergency eyewash station is disclosed. The kit includes a sterile eyewash fluid source. A pump assembly having an input port and an output port is also included. The input port is configured to connect to a dispensing structure of a plumbed eyewash station and the output port is configured to connect to the sterile eyewash fluid source. A drive assembly is configured to drive the pump assembly to draw sterile eyewash fluid from the sterile eyewash fluid source and discharge it through the dispensing structure of the plumbed eyewash station. The eyewash fluid discharged from the dispensing structure is configured to drain through a discharge of the plumbed eyewash station and away from the plumbed eyewash station.

Retrofit kit and method of retrofitting a plumbed emergency eyewash station

A pump assembly for an emergency eyewash station and method of retrofitting a plumbed emergency eyewash station is disclosed. The pump is configured into two parts, an impeller assembly and a drive assembly, that are configured to couple together. The impeller assembly is isolated from the drive assembly and can be easily replaced to ensure a sterile fluid path is maintained for the eyewash fluid. The drive assembly can be fluid powered or an electric motor as desired. The present invention allows a plumbed eyewash station to be retrofitted to use a sterile eyewash fluid. The present invention can also be used in portable eyewash station units too.

The present invention provides an endoscopic accessory control system that resides externally of the endoscope. The system comprises the endoscopic accessory with a working end to be placed at the distal end of the endoscope, a control sheath extending proximally external to the endoscope and a control handle joined to the proximal end of the control sheath. The control handle is slidably mounted to the exterior surface of the endoscope shaft and is configured to permit grasping of both the shaft and the handle. With the control handle and endoscope shaft grasped with one hand, the other hand of the user is left free to manipulate the endoscope distal tip controls. Additionally, the external arrangement of the control sheath leaves the working channel of the endoscope free for use of accessories or operations.

Systems and techniques relating to a microscope with an adjustable stage are described. A microscope includes a base, a support arm attached to and extending upwardly from the base, a head attached to the support arm, the head including a lens, and an eyepiece attached to the head. A stage is releasably attachable to the support arm between the head and the base at multiple locations, providing multiple working distances between a lower surface of the head and an upper surface of the stage. When the stage is attached to the support arm at a location, a working distance between the lower surface of the head and the upper surface of the stage is further adjustable to an either greater or lesser working distance. In another embodiment, microscopic and macroscopic viewing can both be provided using a lens changer with multiple lens positioned radially about an axis of rotation.

The present invention provides a ligating band dispenser that is mounted on the distal end of an endoscope. The ligator is configured to deliver multiple ligating bands to a plurality of internal sites in a patient. The ligating bands are carried on a tubular band carrier member that is retractable relative to the distal end of the endoscope in order to preserve visibility through the endoscope during navigation, then extendable to define a suction chamber for tissue aspiration during band delivery. A tubular band driver member is slidable over the band carrier member and engages bands individually to push them off the distal end of the band carrier and onto a selected treatment site. A single-hand operated control handle for selectively operating the extension of the band carrier and movement of the band driver to release a band is also provided and is slidably and removably mounted to the endoscope shaft.
