An endoscopic tissue separator surgical device and method. The device has a multi-lumen shaft having proximal and distal ends, a central lumen for accepting an endoscope, and at least two fluid lumens, with a head coupled to the distal end of the shaft and a handle coupled to the proximal end. The head has an endoscope port and at least two fluid ports whose centers are all disposed along an arcuate line of curvature, while the handle has at least two fluid supply ports. Gas and fluid may be conveyed through the shaft from the handle to the head in the at least two fluid lumens separate from the lumen for accepting an endoscope. At least one lumen of the multi-lumen shaft may house a stainless steel tube with an inside diameter of sufficient size to accept an endoscope.

The present invention provides a manual or automated device, system, and method for the monitoring and administration of fluids into a patient. The invention determines if a proper infusion site is being maintained by stopping the infusion fluid, creating a negative pressure differential between the device and the patient, and observing either manually or automatically the fluid being drawn into the device. The presence or absence of blood in the device is an indication of a failed or faulty infusion site depending on the condition being monitored. The system may also be used to inspect the patient's blood for certain characteristics, and to monitor the characteristics of the infusate being delivered to the patient. The invention may be used for either intermittent or continuous injection and may be used separately of other patient care devices, or integrated into or with them.

An adaptable handling system featuring a boundary subsystem and one or more robots. Each robot typically includes a chassis, a container lift mechanism moveable with respect to the robot chassis for transporting at least one container, a drive subsystem for maneuvering the chassis, a boundary sensing subsystem, a container detection subsystem, and a controller. The controller is responsive to the boundary sensing subsystem and the container detection subsystem and is configured to control the drive subsystem to follow a boundary once intercepted until a container is detected and turn until another container is detected. The controller then controls the container lift mechanism to place a transported container proximate the second detected container.

An adaptable container handling robot includes a chassis, a container transport mechanism, a drive subsystem for maneuvering the chassis, a boundary sensing subsystem configured to reduce adverse effects of outdoor deployment, and a controller subsystem responsive to the boundary sensing subsystem. The controller subsystem is configured to detect a boundary, control the drive subsystem to turn in a given direction to align the robot with the boundary, and control the drive subsystem to follow the boundary.

A system for automatically monitoring an infusion in a patient receiving an infusion from a fluid source, the system including: an infusion monitoring device comprising: a fluid valve, disposed in a fluid connection between the fluid source and the patient, and operable for preventing or allowing the flow of fluid from the fluid source to the patient; a variable volume chamber, fluidly coupled between the fluid valve and the patient, for allowing the creation of a pressure differential between the variable volume chamber and the patient; and a fluid inspection window, disposed in the fluid connection between the variable volume chamber and the patient, for allowing a view of fluid drawn from the patient into the infusion monitoring device when the fluid valve is closed and the variable volume chamber creates a negative pressure differential between the variable volume chamber and the patient.

An automated system for transporting items between variable endpoints includes a guidance system for identifying the endpoints and at least one autonomous mobile robot interacting with the guidance system for automatically moving items between the endpoints. The at least one robot is configured to (a) collect an item to be transported at a source end point, (b) travel to a destination endpoint utilizing the guidance system to locate the destination endpoint, (c) deliver the item to the destination endpoint, and (d) repeat (a) through (c) for a given set of items. The guidance system is dynamically reconfigurable to identify new endpoints.

A system is provided for processing container-grown plants positioned in a given area. The system includes a processing station positioned in the area for processing the container-grown plants. It also includes one or more autonomous mobile container handling robots configured to: (i) travel to a source location in the area and pick up a container-grown plant, (ii) transport the container-grown plant to the processing station where a process is performed on the container-grown plant, (iii) transport the container-grown plant from the processing station to a destination location in the area, (iv) deposit the container-grown plant at the destination location, and (v) repeat (i) through (iv) for a set of container-grown plants in the source location.
