Claim 1
Independent Claim
184 words
IN A TESTING APPARATUS FOR DETERMINING THE BLOOD GROUP OF A PATIENT,S BLOOD, THE COMBINATION OF A PLURALITY OF SEPARATE TEST TUBE LIKE ELEMENTS EACH BEING CAPABLE OF HOLDING A LIQUID SAMPLE, SAID ELEMENTS BEING LINEARLY ARRANGED AND JOINED TOGETHER TO FORM A SINGLE UNITARY MULTIPLE RECEPTACLE MEMBER HAVING SEPARATE CHAMBERS FOR DIRECTLY RECEIVING BLOOD COMPONENT SAMPLES TO BE ESTED, AN A THIN WALLED, FLATTENED TUBULAR INDICIA MEMBER HAVING TWO PARALLEL SIDEWALLS JOINEDBY END WALLS AND OPEN AT TOP AND BOTTOM AND ADAPTED TO SURROUND THE UPPER PORTION OF SAID MULTIPLE RECEPTACLE MEMBER, SAID INDICIA MEMBER BEING FURTHER ADAPTED TO BE REMOVABLY ATTACHED TO SAID MULTIPLE RECEPTACLE MEMBER TO FORM AN INTEGRAL TEST UNIT, SAID INDICIA MEMBER HAVING A DEPTH FROM TOP TO BOTTOM SUFFICIENT TO BEMARKED ADJACENT EACH TEST TUBE LIKE ELEMENT WITH A LEGEN INDICATIVE OF THE REAGENT TO BE ADDED TO THAT ELEMENT IN CONDUCTING A BLOOD GROUP TEST, WHEREBY AFTER A TEST IS COMPLETED THE TEST UNIT CAN BE READILY SEPARATED AND THE MULTIPLE RECEPTACLE MEMBER DISCARDED WHILE SAID INDICIA MEMBER IS AVAILABLE FOR UE ON ANOTHER MULTIPLE RECEPTACLE MEMBER.

Claim 3
Dependent Claim
17 words
The combination according to claim 1 wherein said multiple receptacle member, is a disposable integrally molded unit.
Claim 4
Dependent Claim
24 words
The combination according to claim 1 wherein the indicia member markings are in the form of labels that are adhered to said indicia member.
Claim 5
Dependent Claim
37 words
The combination according to claim 1 wherein said multiple receptacle member includes a ledge like element surrounding said member against which said indicia member abuts and which limits the relative positions of said receptacle and indicia members.
Claim 6
Dependent Claim
57 words
The combination according to claim 4 wherein said indicia member fits around the top part of said receptacle member and is dimensioned such that when in abutting relationship with the ledge like element of said receptacle member the tops of the sample chambers of said receptacle member are substantially aligned with the top of said indicia member.
Claim 7
Dependent Claim
17 words
The combination according to claim 1 wherein said indicia member is frictionally joined to said receptacle member.
Claim 8
Dependent Claim
55 words
The combination according to claim 1 including a rack means having an upper surface with an elongated opening through which the lower part of the integral test unit projects but which rack means supports the integral test unit with the legends on said indicia member being visible above the upper surface of said rack means.
Claim 9
Dependent Claim
61 words
The combination according to claim 4, including rack means comprising two elements spaced one above the other, the topmost element having an opening through which said receptacle member and said indicia member fit, and the lower element having an opening through which the lower part of said receptacle member projects but which supports the ledge like element of said receptacle member.
Claim 10
Dependent Claim
81 words
The combination according to claim 7 wherein the upper surface of said rack means is provided with a pluraliTy of additional elongated openings arranged in side by side relationship to form test stations, said upper surface being marked adjacent each opening with an indicia to identify the test station formed by the opening, and including additional indicia members for each test station, each indicia member being given an identifying indicia to correspond with the identifying indicia of an associated test station.
Claim 11
Dependent Claim
43 words
The combination according to claim 9 wherein each test station opening is shaped differently at each of its ends, and each indicia member has corresponding shapes at its ends, whereby an indicia member can be placed in said opening with one orientation only.
Claim 12
Dependent Claim
35 words
The combination according to claim 1 including cooperating means on said multiple receptacle member and on said indicia member which permit said indicia member to be attached to said receptacle member with only one orientation.
Claim 13
Dependent Claim
52 words
The combination according to claim 11 wherein said cooperating means include rib means on said receptacle member and complimentary rib means on said indicia member that interfere with said rib means on said receptacle member when said indicia member is attempted to be placed on said receptacle member in a reversed direction.
