CONTAINER ASSEMBLY WITH IDENTIFICATION MEANS Filed Aug. 21, 1964 4 Sheets-Sheet 4 INVENTOR. KJACK lseeeu Army/v6 United States Patent 3,503,265 CONTAINER ASSEMBLY WITH IDENTIFICATION MEANS Jack Isreeli, Mamaroneck, N.Y., assignor to Technicon Corporation, Chauncey, N.Y., a corporation of New York Filed Aug. 21, 1964, Ser. No. 391,093 Int. Cl. G01n 1/00 US. Cl. 73-423 4 Claims ABSTRACT OF THE DISCLOSURE This invention relates to the automatic identification of articles, and more particularly to the automatic identification of identically coded pairs of articles.

A major problem in many analytic procedures involves insuring that the results of an analysis of a sample are positively correlated with the sample which was analyzed. A further problem involves insuring that the sample which was analyzed (and the results of the analysis) are positively correlated with the supply from which the sample was taken. A prime example of these problems is found in the operation of a blood bank. Customarily, a supply of blood is drawn from a donor. A sample of the drawn blood is analyzed, inter alia, for blood type. The blood type is correlated to the supply of drawn blood. The supply of typed blood is given to a patient requiring blood of that particular type. The customary system is fraught with potential clerical errors. Initially, the blood is drawn separately into a main storage container, and separately into an independent sample storage container. Identification numbers are manually placed on these containers. The samples are each analyzed and the blood type determined. The blood type is manually recorded in correlation with the identification number. When blood of a particular type is required, the identification number of a storage container having that type is manually obtained, and the corresponding storage container is manually selected. If blood of an incorrect type is given to a patient the result may be fatal.

An object of this invention is the provision of an apparatus and a method to insure that both the main storage container and the sample storage container receive identical identification numbers.

Another object of this invention is the provision of an apparatus and a method to insure that the sample identification number is correlated with the analysis results of the particular sample.

Still another object of this invention is the provision of a novel sample container and identification number carrier from which the sample for analysis may be automatically removed and the identification number automatically read.

Yet another object is the provision of an apparatus and a method for automatically recording identification numbers of samples in an automatic analysis apparatus.

A feature of this invention is the provision of a main storage container and a sample storage container which are concurrently marked with uniquely identifying indicia by a single group of indicia applying means, and a means for automatically reading the identifying indicia.

These and other objects, features and advantages will become apparent by reference to the following description of the invention considered in conjunction with the accompanying drawings in which:

FIGS. 13 and 14 are detail views in perspective, partially in section, showing the principle of the readout method.

A blood donation main storage container 10, is shown in FIGS. 1 and 3, to comprise a body portion 12 and a foldover inlet and outlet spout 14 made of two layers of

plastic

16 and 18 which are heat sealed together along their peripheries. An elongated member or indicia carrier 20, which may be made of a thin, stiff plastic, has one end 22 thereof fixed to the container 10 by being sealed between the two

layers

16 and 18, but not in communication with the chamber 24 formed by these layers. The other end 26 of the elongated member is fixed to a sample container 28. The sample container 28 comprises a tubular body portion 30, closed at its lower end, having an elongated boss 32 to which the end 26 is fixed by suitable means, such as adhesive. A removable stopper 34 may be inserted in the upper end of the body portion 30. The main storage container 10, the sample storage container 28 and the interconnecting indicia carrier 20 together form a container assembly.

Prior to use, the container assembly is provided with a unique identification number. The coding system illus-. trated herein utilizes a binary system with a parity checking digit. That is, each decimal digit is represented by four binary digits plus a parity checking digit. Each binary digit is represented by the presence or absence of a punched hole. Nine decimal digits are provided for in the illustrated embodiment, but any number and any binary based coding system, such as a three out of five code, may e provided as required.

FIG. 7 illustrates the coding system utilizing notches in the edge of a carrier. The topmost notch 40 is used to check the vertical alignment of the carrier during the reading operation. The next five notch positions 42 provide the first decimal digit. The next five notch positions 44 provide the second decimal digit. The succeeding pluralities of five

notch positions

46, 48, 50, 52, 54, 56 and 58 respectively provide the third through ninth decimal digits.

As shown in FIGS. 1 and 4, the indicia carrier 20 of the container assembly is provided with a line of severance 60, such as a scored line. A plurality of lozenge shaped holes are punched into the carrier along the line of severance, so that one-half of each hole is on each side of the line of severance. The presence or absence of a hole is determined by the particular identification number to be given to the particular container assembly as converted into bi-quinary code. Each lozenge shaped hole may be punched by a single punch element in a punch assembly, not shown. The punch assembly is advantageously a gang punch wherein all of the holes are concurrently punched, insuring accurate spacing between the holes. Concurrently with the punching, the equivalent decimal digit may be printed on both sides of each group of holes.

The complete and punched container assembly is brought to the donor, and blood is drawn from the donor, through a collection tube, not shown, attached to the spout 14, into the chamber 24 of the main storage container 10. A quantity of the drawn blood is then dispensed from the collection tube or the spout into the sample storage container 28. The spout 14 is closed, and the tubular body portion is stoppered. As shown in FIGS. and 6, the indicia carrier 20 is now severed along the line of severance 60, separating the two containers. Each container retains a portion of the carrier 20, and both of the edges resulting from the severance has a row of V shaped notches 64 and lands 65 which is identical in spacing with the single row of lozenge shaped holes originally provided in the carrier. Thus the identification indicia provided with the main container is invariably identical to the identification indicia provided with the sample container 28.

The analysis of the blood for blood type in each sample container 28 is advantageously performed in an automatic analyzer apparatus of the type shown in the United States patent application of William J. Smythe, S.N. 221,570, filed Sept. 5, 1962, and assigned to the assignee of this application. Each of the sample containers is placed in a sampler for sequential sampling and reading. A sampler 66 is shown in FIGS. 2 and 10. The sampler 66 includes an endless sprocket chain 68. The links of the chain are formed of spaced apart pairs of plates. Alternate links have a pair of ears 70 upstanding from the upper plate 76 of the link. A sample container carrier 74 stands up from the top plate 72 and is riveted at 76 between and to the ears 70. The carrier 74 has a tubular body portion 78, with an open top, and a vertical slot 80 which extends from the open top to a level 82 above the cars 70. The inner diameter of the carrier tubular body portion 78 is equal to the outer diameter of the sample container tubular body portion 30, and the width and the thickness of the slot 80 are equal to the width and the thickness of the boss 32. The sample container is slid into the carrier, with the underside of the boss 32 resting on the level 82. The carrier 74 is fixed to chain 68 by the rivet 76 and is constrained against movement with respect thereto. The container 28 is constrained against rotation with respect to the carrier by the interlocking boss and slot, and is vertically aligned by the boss and the level 82. The sample container indicia carrier end 26 is fixed to the boss 32 and disposed without the carrier 74. By this arrangement the indicia carrier end 26 is fixedly located with respect to the chain.

The chain is provided with a plurality of carriers 74, fixed to alternate links, and guided between sprocket wheels 84. Although a substantially rectangular configuration of chain is shown in FIG. 2, a serpentine or other configuration may be utilized to provide a greater length of chain and a greater number of carriers in a limited area. The chain sequentially conveys each of the carriers past a first station 86 whereat the sample is automatically removed for analysis from the sample container 28, and a second station 88 whereat the identification number of the sample is automatically read from the indicia carrier end 26. The chain is intermittently driven by suitable power means, not shown.

A sample removal tube 89 is disposed at the first station. When the chain presents a sample container at the first station, the tube 89 is brought over to and down into the container, and a sample is aspirated out through a conduit 90 into the automatic analysis apparatus 91. The tube is then brought out of the container, and in due course another container is presented. A suitable sample tube which is translated in a given plane is shown in FIG. 4 of the United States patent application of Jack Isreeli and Theodore Bilichniansky, S.N. 246,967, filed Dec. 26, 1962, and assigned to the assignee of this application. Each aspirated sample is sequentially analyzed, and the results of the analysis are charted as one or more curves for each sample by a recorder 92. The recorder may advantageously be of the type shown in the United States patent application of Milton H. Pelavin and William J. Smythe, S.N. 298,762, filed July 30, 1963, and assigned to the asignee of this application. The analysis of each sample, which is performed on a continuous flow of samples, takes a finite interval of time from the aspiration of the sample to the charting of the results. During this interval, the chain continues to advance the sample corrtainer from the first station towards the second station. When the recorder is charting the results of the analysis of a particular sample, the container of that particular sample reaches the second station 88.

The second station is disposed at a 180 bend in the chain. A multi-concave-surfaced element 92 is mounted on a rigidly vertical pivot 94 at the center of the bend. As the carrier approaches the bend 74 it enters one of the concave surfaces 96 and travels 90 around with the element 92 to the second station.

A readout mechanism 98 is disposed at the second station to automatically read the identification number from the indicia carrier end 26 on the sample container 28.

The readout mechanism 98 includes a vertical bracket 100 which is fixed to a horizontal chassis 102 by an angle bracket 104 and which has a horizontal upper arm 106. A vertical insulator block 108 is mounted for oscillation about a vertical axis on an upper pivot 110 in the upper arm 106 and a lower pivot 112 in the chassis 102. A bracket has a vertical central portion 114 fixed to block 108, a lower horizontal arm 116 extending forwardly from the central portion and a mediate vertical arm 118 extending forwardly from the central portion. A cam follower 120 is mounted to the forward free end of the horizontal arm 116. A cam 122 is mounted on a shaft 124 by its integral collar 126 and a set screw 128 to engage the cam follower, The shaft passes through the chassis and is driven by suitable means, not shown.

An insulator block 130, an insulator block 132, and an insulator block 134 are fixed to the rear of the insulator block 108. The forward face of the block 134 is provided with a plurality of horizontal, spaced apart, grooves, and a plurality of feeler wires 136, one in each groove, are clamped between the

blocks

132 and 134. The wires extend laterally on both sides of the block 134. The right hand free ends of the wires are adapted to sense the notches, or the absence thereof, on the indicia carrier end portion 26. The left hand free ends of the wires are respectively connected to individual output conductors 138. A resilient, curved, ground bus is fixed between the bracket vertical central portion 114 and the insulator block 108. The left hand end of the ground bus 140 is connected to a ground conductor 142. The right hand free end of the bus is provided with a sharp, vertical bend which is slightly spaced away from the free ends of the feel wires 136. The spacing of the bus from the feeler wires is controlled by a screw 144 threaded into a forward face of the block 108 and the right hand vertical edge of the block 130. A stop screw 146 is mounted through the

brackets

104 and 100 to limit the maximum rotation clockwise of the arm 118 and the rotatable assembly about the

pivots

110 and 112. A compression spring 148 is disposed about the screw 146 between the arm 118 and the bracket 100 to bias the arm 118 counterclockwise. A snap action switch 150 has an actuator arm 152 disposed to be operated by the high point of the cam 122. When the carrier 74 has traveled 90 around the bend to the readout position, the chain drive is halted. Any vertical play of the carrier is precluded by the vertical element 92 which is backing up the carrier. The cam 122 permits the spring 148 to rotate the rotatable assembly counter clockwise, bringing the feeler wires against the edge of the indicia carrier end portion 26. A wire is provided for each notch position in the portion 26, The vertical plane of the portion 26 may be disposed at a 6 angle to the vertical plane of the wires. As the assembly rotates counter clockwise, those feeler wires which are adjacent notches will respectively enter the notches and continue to travel counter clockwise until the rotation of assembly is halted by the low portion of the cam 122, just before the wires reach the bottom of the notches. It may be noted that the notches 64 are V shaped, and therefore will permit the entrance of slightly misaligned wires, but not neighboring wires. Those wires which are not adjacent notches, will abut the lands 65 between the notches, and as the assembly rotates, will be deflected into engagement with the bend 141 in the ground bus. When the high point of the cam operates the switch 150, associated circuitry, not shown, will apply a test potential to the conductors 138. Those feeler wires which are deflected by lands will provide continuity to ground through the ground bus 140 and wire 142. Those feeler wires which enter notches will not provide continuity.

The topmost feeler wire, entering a notch, indicates that the indicia carrier end portion 26 is correctly vertically aligned with respect to the feeler wires. The next five feeler wires provide an indication of the first decimal digit. The lower groups, by five, of feeler wires provide an indication of the other decimal digits. The output conductors 138 are taken to a code converter and printing head 154 which is disposed on the recorder 92 adjacent the recording pens. The printing head prints the decimal identification number of the sample adjacent the curves which provide the results of the analysis of that sample. After the switch 150 is deoperated, the cam 122 rotates the rotatable assembly clockwise, against the bias of the spring 148, withdrawing the feeler wires from the indicia carrier end portion 26. The chain drive is energized to present the succeeding carrier to the readout position. If it is desired to minimize the arcuate distance through which the feeler wires are oscillated, the indicia carrier end portion 26 may be snapped past the ends of the feeler wires, deflecting them and the end portion, as the sample container carrier is moved from 90 to 180 from chain, or by mounting the card at 6 and having the slot 5 the indicia may also be provided by magnetic ink stripes which are printed on both sides of the severance line, or phosphorescent ink stripes, which, when the indicia carrier is severed, may be sensed by rows of magnetic or photo detectors. It may be noted that sensing the indicia at the center of a curve, i.e. rotating the indicia carrier, permits engagement and disengagement of the indicia with the sensors to be accomplished Within a small linear distance.

The indicia on the indicia carrier end portion 22 attached to the main container 12 may be read by a similar readout mechanism and used to control the correlation of the main container with the results of the analysis.
