Abstract
Abstract A method and apparatus for the distribution of dose portions of liquid samples for clinical analysis. Successive liquid samples are retained in respective primary receptacles which are located on a primary conveyor adapted to move along a predefined path. Each receptacle is coded. A plurality of secondary receptacles are located in one or more secondary conveyor lines extending along a path at an angle to that of the primary conveyor. The conveyors are indexed with respect to each other and the samples are distributed in doses in accordance with a predefined program from each of said primary receptacles into one or more of said secondary receptacles correspondingly coded.

Claim 1
Independent Claim
174 words
APPARATUS FOR THE DISTRIBUTION OF DOSED PORTIONS OF LIQUID SAMPLES FOR CLINICAL ANALYSIS FROM THE HYPODERMIC SYRINGE USED TO OBTAIN THE SAME FROM THE PATIENT, SAID HYPODERMIC SYRINGE HAVING A BARREL AND A PISTON LOCATED THEREIN, COMPRISING A PRIMARY CONVEYOR MOVING ALONG A PREDEFINED PATH, MEANS FOR LOCATING SAID SYRINGE ON SAID PRIMERY CONVEYOR, MEANS FOR CODING SAID SYRINGE, AT LEAST ONE SECONDARY CONVEYOR ADAPTED TO CONTAIN ONE OR MORE DOSE RECEIVING RECEPTACLES, SAID PRIMERY CONVEYOR EXTENDING IN A TRANSVERSE PATH OVER THE PATH OF THE SECONDARY CONVEYOR, MEANS FOR INDEXING SAID CONVEYORS INDIVIDUALLY WITH RESPECT TO EACH OTHER TO PLACE A SYRINGE IN SUCCESSIVE PROXIMITY TO ONE OR MORE OF SAID SECONDARY RECEPTACLES, A FLEXIBLE TUBE CONNECTED TO THE OUTLET OF SAID SYRINGE TO EXTEND INTO EACH OF THE SUCCESSIVELY ADJACENT DOSE RECEPTACLES, MEANS FOR INDEXING THE PLUNGER OF SAID SYRINGE TO DISCHARGE A PREDEFINED PORTION OF SAID SAMPLE FROM SAID SYRINGE INTO SELECTED ONES OF SAID DOSE RECPTACLES, AND MEANS FOR CODING SAID SECONDARY RECEPTACLES RECEIVING SAID DOSE CORRESPONDINGLY WITH THE SYRINGE.

Claim 3
Dependent Claim
35 words
The apparatus according to claim 1 including sensing means responsive to the presence of liquid in said outlet tube and switch means responsive to said sensing means for controlling said means for discharging said syringe.
Claim 4
Dependent Claim
18 words
The apparatus according to claim 2 including photocell means for sensing the presence of liquid in said tube.
Claim 5
Dependent Claim
32 words
The apparatus according to claim 3 wherein said means for discharging said syring comprises a ram adapted to engage the pistons of said syringe and actuator means for incrementally moving the same.
Claim 6
Dependent Claim
57 words
Apparatus in according with claim 2 including storage means remote from said primary conveyor, a distributor for selectively locating said syringe on said primary conveyor or in said storage means and switch means for controlling the distributor to locate said syringe in said storage means in the event of there being too much liquid in the syringe.
Claim 7
Dependent Claim
38 words
The apparatus in according with claim 2, wherein the switch means operates in two stages, the first stage acting to fill said tube, and after the first stage a signal is transmitted when the tube is completely filled.
Claim 8
Dependent Claim
