Patent number: 4420566Abstract: A method and apparatus are disclosed for detecting sample fluid on an analysis slide of the type which is used to perform quantitative analyses. The apparatus comprises means for projecting radiation comprising wavelengths absorbed by water onto the slide and means for measuring the intensity of radiation received from the slide, both before fluid is metered on the slide and after fluid has been metered thereon. The difference between radiation received from a wet slide and from a dry slide is compared with known values to determine if the slide contains sufficient fluid for a suitable test result.Type: GrantFiled: June 10, 1982Date of Patent: December 13, 1983Assignee: Eastman Kodak CompanyInventors: Thomas C. Jessop, Donald De Jager
-
Patent number: 4340390Abstract: A method and apparatus are disclosed for repeatedly and accurately depositing predetermined amounts of fluid, especially biological fluids, onto generally planar analysis slides. The apparatus comprises a dispenser which is adapted to pick up a disposable metering tip, aspirate fluid into the tip, meter a predetermined amount of fluid from the tip onto an analysis slide, and eject the tip after the metering operation.Type: GrantFiled: May 6, 1981Date of Patent: July 20, 1982Assignee: Eastman Kodak CompanyInventors: Richard A. Collins, Glenn E. Tersteeg, Thomas C. Jessop
-
Patent number: 4321122Abstract: This disclosure relates to a method and apparatus for forming electrical contact with an analysis slide of the potentiometric type. A probe unit, electrically connected to an electrometer, comprises a plurality of probe tips which are adapted to penetrate into the electrodes of an analysis slide and to move laterally in a direction generally parallel to the electrode layers after penetration. A means is provided for preloading the probe tips to control the force required to effect lateral movement of the tips.Type: GrantFiled: March 31, 1980Date of Patent: March 23, 1982Assignee: Eastman Kodak CompanyInventors: Rodney J. Whitcomb, Henry S. Adamski
-
Patent number: 4279861Abstract: Apparatus is disclosed which is adapted to receive a removable cartridge containing material for use in the apparatus, for example, test elements for use in performing analyses of biological fluids. A cartridge discriminator is provided to insure that only a cartridge having a code means corresponding to a selected material can be loaded in the apparatus, and to program the apparatus to operate in a mode which conforms to the selected material. A control means serves to adjust the discriminator for a selected material.Type: GrantFiled: May 9, 1979Date of Patent: July 21, 1981Assignee: Eastman Kodak CompanyInventor: Thomas C. Jessop
-
Patent number: 4277440Abstract: Apparatus is disclosed which is adapted to repeatedly and accurately dispense predetermined amounts of fluid, especially biological fluids, onto generally planar test elements. The apparatus comprises a metering pump actuated by an escapement mechanism which moves the pump in precise increments. The fluids are dispensed through a pair of metering tips which are spaced a given distance from the test element.Type: GrantFiled: July 2, 1979Date of Patent: July 7, 1981Assignee: Eastman Kodak CompanyInventors: Thomas C. Jessop, William L. Smith
-
Patent number: 4269803Abstract: A slide transfer mechanism is disclosed for advancing an analysis slide through a plurality of work stations in a chemical analyzer. The transfer mechanism comprises a pair of slidable members which are movable together to advance slides in each of the stations and are movable independently of each other to advance slides in less than all of the stations. The slides are releasably held by spring means in each of the work stations.Type: GrantFiled: July 2, 1979Date of Patent: May 26, 1981Assignee: Eastman Kodak CompanyInventor: Thomas C. Jessop
-
Patent number: 4257862Abstract: A method and apparatus are disclosed for performing chemical analysis on selected fluids. The fluids are dispensed onto a test element which is transported to an analysis device where a radiometer or potentiometer is provided for measuring a characteristic of the test element resulting from the fluid deposited thereon.Type: GrantFiled: July 24, 1978Date of Patent: March 24, 1981Assignee: Eastman Kodak CompanyInventors: Paul N. Schnipelsky, Raymond F. Jakubowicz
-
Patent number: 4224032Abstract: A method and apparatus are disclosed for performing chemical analysis on selected fluids. The apparatus comprises a turntable which carries a plurality of cartridges containing test slides. A transfer mechanism is adapted to receive a slide from a selected cartridge, transport the slide to a metering device where a precise amount of fluid is deposited thereon, and then deliver the slide to a conveyor which moves the slide through an incubator. A radiometric reading of the slide is taken while it is in the incubator.Type: GrantFiled: December 5, 1977Date of Patent: September 23, 1980Assignee: Eastman Kodak CompanyInventors: Clyde P. Glover, James E. Ferris, Robert J. Meyer, Edward Muka
-
Patent number: 4219529Abstract: An incubator is provided for use with a chemical analyzer of the type in which a fluid sample is metered onto a test slide which is analyzed after a suitable period of incubation. The incubator includes a temperature-controlled chamber having a conveyor mounted therein which comprises a plurality of slide holding members. A drive means for the conveyor is adapted to successively advance the slide holding members past load and unload slots located adjacent slide transfer mechanisms.Type: GrantFiled: November 28, 1977Date of Patent: August 26, 1980Assignee: Eastman Kodak CompanyInventors: Glenn E. Tersteeg, Louis C. Nosco, Robert J. Meyer, Rodney J. Whitcomb

Patent number: 4152390Abstract: A chemical analyzer is disclosed for performing analysis on selected fluids. The analyzer comprises a plurality of cartridges containing test slides. A slide transfer mechanism is adapted to feed a slide from a selected cartridge, transport the slide to a metering device where a precise amount of fluid is deposited thereon, deliver the slide to conveyor means which moves the element through an incubator, and transport the slide to an analysis means after a predetermined time in the incubator.Type: GrantFiled: December 2, 1977Date of Patent: May 1, 1979Assignee: Eastman Kodak CompanyInventors: Louis C. Nosco, Henry S. Adamski, Anthony P. Di Fulvio
-
Patent number: 4142656Abstract: Apparatus is disclosed for drop-by-drop metering of fluids, especially biological fluids. A metering head, connected to a pressure generating means, is adapted to be selectively moved into fluid communication with a sample cup through which the fluid is metered.Type: GrantFiled: December 17, 1976Date of Patent: March 6, 1979Assignee: Eastman Kodak CompanyInventors: Michael R. Smith, James E. Ferris
