Title: Blood bag system for separation and isolation of neocytes and gerocytes
Inventor: NELSON EDWARD J
IPC: A61M1/02
Filed: 1992-09-15
Abstract: Abstract of the Disclosure A generally flat, elongated edge-sealed polymeric blood bag having a length to width ratio of at least 2 to 1 and one end portion in tapering communication with a connected single tubing which in turn is in closed communication via a Y-connector with both a bag access port and at least one other Y-connector.  The second Y-connector is in closed communication with at least one auxiliary bag, preferably two auxiliary bags.  Once the upper neocyte portion is expressed from the elongated blood bag the lower, more dense gerocytes can be saved in the original elongated bag or expressed into another connected bag via the Y-connector assembly for subsequent use or storage.  The bag system is. especially useful for separating and isolating both components of a neocyte/gerocyte red blood cell mixture in an open system and for providing a means for saving the otherwise discarded gerocytes for subsequent use.  A physiological solution can be introduced via the Y-connector assemblies into the elongated bag to reconstitute the dense gerocytes.

Filed: 1993-01-12
Abstract: An apparatus and method are disclosed for continuous, on-line monitoring of extracorporeal blood in a blood path. A shell has a blood inlet port, a blood outlet port and two compartments: a blood compartment and a plasma compartment separated by a semi-permeable membrane that allows plasma to pass, but not red blood cells.

Filed: 1993-04-16
Abstract: ABSTRACT OF THE DISCLOSURE       A movie camera system having a function of projecting an image of an object being presently shot or previously shot on an external screen as well as a function of monitoring the image and a method of displaying a video signal therein.  A composite video signal from a camera section or a VCR section is processed by a video signal processor in a display section so that it can be displayed on a display device which is of a matrixed form of pixels.  The processed video signals from the video signal processor correspond respectively to red, green and blue color signals.  Arrangements of the processed video signals are changed according to whether a selected function is the projecting function or the view finding function.          According to the selected function, an optical image resulting from the video signals displayed on the display device is lighted by a large or small amount or light from a light source at the rear.  The user can view or monitor the image on the display device through a focus lens unit at the front portion thereof.   The image on the display device is also projected on an external screen by the large amount of light from the light source.  A memory may be used to change the arrangement of the video signal before application to the display section.  In this case, the display section functions only to sequentially display the video signals therein.

Abstract: A backhoe having a swivel deck supporting a driver's section and a hydraulically operable boom assembly. This backhoe includes a detecting device for detecting a position, direction of movement and velocity of movement of a bucket relative to the driver's section, and a control device for controlling the boom assembly based on detection values provided by the detecting device. The control device has a function to prohibit operation of the bucket when the bucket moves inwardly of a danger plane A1 or A2 disposed at a predetermined distance. Outwardly of the driver's section. The control device establishes a caution plane C1 or C2 disposed at a predetermined distance outwardly of the danger plane A1 or A2, and has a time estimating function which, when a bucket pin 6a lies in a danger zone B1 or B2 defined by the danger plane and caution plane, computes and estimates time taken for the bucket 6 to reach the danger plane A1 or A2. To realize an ideal decelerated motion, a set time is determined in advance by using a horizontal distance to the danger plane A1 or A2 as a variable. The control device has a decelerating function to decelerate operation of hydraulic cylinders so that the set time and the time estimated agree.

Abstract: A method of producing an instrument face having functional indicia thereon (such as a clock face dial, thermometer face, etc.), allows high quality, multicolor instrument faces to be produced in a cost effective manner even for small runs (e.g. 1-500 units). The instrument face is created in a computer in electronic format, and the computer transmits electronic signals to a color photocopier, to control it to print the instrument face on a sheet of paper. Thesheet of paper may be laminated to a more rigid sheet, e.g. styrene, cardboard, acrylic or plexiglass, and then an instrument face of the appropriate geometric shape and size is cut from the sheet material. The face is assembled with other functional components to produce an operable instrument. The cutting is preferably practiced automatically utilizing a laser cutter under the control of the computer. A scanner or CD ROM may be utilized for inputting data into the computer. A simplified version may be practiced by overlaying a transparency with instrument dial indicia on a color photograph, and color photocopying it, then laminating, cutting, and assembling it into an instrument.
