International Classification:

G06K 9/00

US Classification:

382143, 382124, 235375

Abstract:

A stand alone imaging system is disclosed that captures undistorted, high resolution, stop-action images of objects (e. g. , medicine pills) moving at automation speeds, processes the images in real time, and then performs real-time I/O based control that is a function of the image processing results. The imaging system has a form factor that enables it to be embedded inside a product (e. g. , a pill dispenser). The imaging system also has a flexible I/O system so that a variety of different applications can be handled by changing only the programming and the external hardware connected to the device in which the imaging system is embedded. In the case of pill dispensing and quality control, a miniature, low cost imaging system can be embedded in a pill dispenser to obtain a pill image and then process the image in real time as the pill moves through a counting system. The embedded imaging system processes the images fast enough and with sufficient quality and resolution so as to command a pill counting mechanism to dispense or reject the pill based on the image processing results. Images of the pills can also be sent to a remote location or an archive.

International Classification:

A61M 5/168
A61M 5/142

Abstract:

A fluid injector system includes a control device operatively associated with each of two or more drive components configured to pressurize and inject a first fluid from a first fluid reservoir through a fluid conduit, and at least a second fluid from a second fluid reservoir through the fluid conduit. The fluid conduit is in selective fluid communication with the first and second fluid reservoirs. The control device has at least one processor programmed or configured to actuate a second drive component to pressurize and inject the second fluid through the fluid conduit, and while the second drive component is actuated, actuate a first drive component to introduce intermittent pulses of the first fluid to create a flow front interface between the first fluid and the second fluid in the fluid conduit to prevent backflow of the second fluid through the fluid conduit into the first fluid reservoir.

A61M 5/31

Abstract:

An injector system for delivering a medical fluid may include at least one syringe defining a reservoir operatively connected to a piston; and at least one processor programmed or configured to, based on an air check protocol for detecting air in the reservoir, determine a baseline value comprising baseline compressibility data for the at least one syringe of the injector system, deliver the first amount of the medical fluid from the reservoir; refill the reservoir with a second amount of the medical fluid; based on the air check protocol, perform an air check pressurization sequence by gathering air check compressibility data for the at least one syringe of the injector system; and based on the air check protocol, compare the air check compressibility data with the baseline compressibility data to determine a volume of air present in the reservoir.
