  • the container as above having the additional structure which enables indexing of the container relative to a carrier or rack, and which also permits attachment of identifying members to the container.
  • Structure for feeding lengths of capillary tubing into the barrel of the standard and for supplying the reagent to the container including means for conveying the containers past reagent supply stations and means for connecting desired stations to containers.
  • the first of these applications will be termed the capillary tube application, and the second of these will be termed sample identification application.
  • the invention herein is intended as one aspect of a type of sample testing system for use in hospitals and laboratories where small quantities of raw fluids are processed as, for example, by dilution with ditferent reagents and then tested.
  • the most common fluid which comes to mind is blood, most hematology laboratories being required to perform from several to more than six independent tests on any given patients blood.
  • the invention is not so limited, but may be applied to other types of testing. Consideration of the problems involved in the testing of blood will be readily appreciated and give an understanding of the invention.
  • the batch method enables the positive identification of samples, and this is explained and disclosed in considerable detail in the sample identification application above referred to.
  • the progress of samples through the system can be watched closely, and the apparatus needed to handle the sample containers is relatively simple.
  • automatic or semi-automatic equipment already owned by the laboratory may be used with little or no change or readily modified to fit in with a high-speed system, and without sacrificing the advantages of the identification structures described in said application.
  • the applicants solution of the problem of handling many samples depends upon the use of a capillary tube to gather and/or hold the raw fluid.
  • the raw fluid for example, blood
  • the raw fluid is drawn or forced into a length of capillary tubing of precise internal diameter bore, so that the length of the fluid blood column in the length of tube can be measured linearly and related to volume.
  • the end product is a piece of capillary tubing with an entrained precise volume of the raw fluid.
  • the entire section of tubing is placed in a receptacle with the needed quantity of diluent or reagent needed to make the test sample, and the receptacle is agitated to cause the blood to be diluted and mixed.
  • the invention herein combines the concept of using the capillary tubing to measure out the raw sample liquid, together with a special type of cup or container, so that instead of depending upon the agitation of the container for mixing the raw liquid with the reagent, the reagent is forced through the section of capillary tubing, washing it out and mixing the resulting dilution thoroughly within the receptacle or container. Since there is no actual need for shaking or agitating the container, it may be fixed to a carrier and moved in paths taking it to various stations for functions to be performed on it.
  • the principal advantage and object of the invention is to achieve a degree of automation in the testing of biological and other fluids through the use of the batch method, in which the basic material to be diluted is contained in a section of capillary tubing, and the dilution of this basic material is accomplished in a manner which forces the material from the section of tubing and washes same clean, while mixing the fluid and retaining it in the sample container or cup.
  • An important element of the structure of the invention comprises means for holding the section of capillary tubing in such a manner that the reagent may be flowed through the tubing in a simple manner and with simple apparatus.
  • the container of the invention advantageously can be constructed in accordance with the teachings of the sample identification application, with the result that it may carry identification of the source, test and test results, and additionally may be indexed in mounted condition on a carrier or rack so that a plurality of sample containers may be handled together.
  • the structure for introducing reagent advantageously may include a reading apparatus responsive to the information carried on the identification card of the container. When the container passes a given reader that identifies that type of test requiring the reagent that is dispensed at that same station, the apparatus automatically will stop the movement of the carrier and the reagent will be dispensed into the container.
  • FIG. 1 is a perspective view of a test sample container constructed in accordance with the invention
  • FIG. 2 is a top plane view of the container of FIG. 1;
  • FIG. 3 is a vertical median sectional view through the container of FIG. 1 taken along the line 3-3 and viewed in the indicated direction;
  • FIG. 4 is a horizontal sectional view taken along the line 44 of FIG. 3 and looking in the indicated direction;
  • FIG. 5 is a sectional view through a section of capillary tubing showing the manner in which a quantity of raw fluid is entrained therein in accordance with the teachings of the capillary tubing co-pending application;
  • FIG. 6 is a vertical sectional view similar to that of FIG. 3 but illustrating a simplified form of the container, and having a section of capillary tubing disposed in the hollow standard and a fitting from a source of reagent connected to the standard to enable discharge of the liquid into the standard and through the capillary tube to pro Jerusalem a properly diluted liquid sample;
  • FIG. 7 is a fragmentary vertical sectional view taken through a modified form of the sample container illustrating the manner in which a fitting may be piloted into connection with the top of the hollow standard;
  • FIG. 8 is a fragmentary sectional view taken generally along the line 88 of FIG. 6 and in the indicated direction;
  • FIG. 9 is a top plane view of a modified form of the sample container but shown with the standard not in place to enable consideration of the details of the bottom of the cavity;
  • FIG. 10 is a fragmentary vertical sectional view taken generally along the line 10-10 of FIG. 9 and in the indicated direction, but in this case the standard is in place and a section of capillary tubing is also shown in the barrel of the standard;
  • FIG. 11 is a diagrammatic perspective view showing a conveyor or other carrier having sample containers thereon and in the process of receiving sections of capillary tubing into their hollow standards;
  • FIG. 12 is a diagrammatic perspective view showing a carrier or rack having sample containers disposed thereon in the process of being filled with reagent directed through their standards and the capillary tubing disposed in the barrels of the respective standards.
  • the sample container of the invention provides the key to many advantages which are achieved, and principally depends for its usefulness upon the concept of the capillary tube co-pending application.
  • the container has a central vertical hollow standard forming a barrel into which the section of capillary tubing is inserted as a cartridge.
  • the barrel is connected by an unobstructed fluid passageway with the interior of the container utilizing a structure that supports the standard and the section of tubing without blocking the lower end of the capillary section.
  • the upper end of the standard will be connectible with a fitting for introducing the reagent and may have pilot means to enable a fluid-tight connection in an automated system.
  • the advantages of automation may be achieved by integrating the concept of the container with capilary-holding standard into a conveyor or carrier to handle plural numbers of such containers.
  • FIG. 1 there is illustrated a container or cup 20 which may be molded of some suitable synthetic resin that is compatible with the fluids it is intended to carry.
  • the container 20 is disposable, and hence any economical material may be used for its manufacture.
  • a central cavity is formed in the container at 22 terminating on its lower end at the level 24 which may be considered the bottom of the cavity, although, as will be seen, structure is provided for fluid to be disposed below this level.
  • the walls forming the cavity are conically tapered, but any configuration of convenience may be utilized.
  • the base 26 of the container is flat to permit the mounting of the same upon a table or flat surface, as will be seen.
  • FIG. 1 There are two formations integral with the container 20, one being the formation 28 which provides a vertical rectangular cross section slot or passageway 30, and the other being a channel configured bracket 32 having a channel 34 with inwardly directed flanges 36 within which an identification card or other member 38 is adapted to be disposed.
  • the member or card 38 is shown in phantom in FIG. 1 and somewhat diagrammatically in FIG. 12, but the details are not needed for an understanding of the invention herein.
  • the identification member 38 is held in the channel 34 by frictional engagement, is indexed therein by means of a suitable perforation formed in the member engaging the integral pin 40 and is substantially longer than the vertical height of the container 20 so that when the container is mounted on a surface as the surface 42 in FIG. 12, the identification member will depend from the edge of the surface 42. Note this dependence in FIG. 1.
  • the purpose of the passageway or socket 30 is to enable the container to be secured to one of the posts such as shown at 44 in FIG. 12, thereby fixing and positioning the container along with several others for consecutive processing or testing.
  • a shallow recess 46 In the center of the bottom of the cavity 22 there is a shallow recess 46, there being a lateral rectangular well 48 which connects with the bottom 24 of the cavity at its upper end and which is deep enough to extend below the recess 46.
  • a central standard 50 is set into the recess 46 the standard being hollow whereby to provide a barrel or bore 52 for reception of a section of capillary tubing as will be explained. It will be seen that there is direct communication between the well 48 and the bar l so that liquid introduced in the barrel 52 will be conducted to the cavity 22. During use the liquid will actually be forced from the barrel 52 into the cavity 22.
  • the standard may be formed of glass or synthetic resin or other inert material, and conveniently may be a length of commercially available plastic tubing, preferably stiff enough to be pressed into the recess 46.
  • FIG. 5 there is illustrated a section of capillary tubing 54 of a predetermined length cut to entrain a known volume of raw test liquid 56 in its bore.
  • FIG. 6 there is illustrated a simplified form of the container, designated but otherwise using the same reference characters as the container 20 previously described. The only differences are that the formations 28 and 32 are not shown, nor is the holow 58 illustrated, this latter being the result of application of the conventional techniques for economical molding.
  • the bottom surface of the container 20' is shown at 26; the standard is secured in the recess 46 so that its barrel 52 may connect with the well 48 to provide direct passageway for liquid from the barrel to the cavity 22.
  • the formulation 32 since the formulation 32 is not used, other means for handling and identification may be used, such as, for example, magnetic.
  • a coating of magnet1c material is symbolically shown at to receive identification information, and a notch at 62 may be used with a suitable lug or projection, such as shown at 64 1n FIG. 11 for indexing the containers 20' in case a plurality are being automatically handled, as, for example, on a conveyor or in a rack.
  • the principal purpose for this illustration is to expalin the manner in which the standard serves to receive the section of capillaryt tubing and tes with a reagent-injecting appara us.
  • a flexible conduit 66 connects from a source of reagent, such as a flask of suitable diluent specified for the test to be made.
  • a fitting 68 serving as a coupler is connected to the conduit 66 and has a hood or flared part 70 that fits closely over the upper end of the standard 50 so that liquid which will be introduced through the condult 66 will be forced through the barrel 52 and will wash the raw liquid 56 through the core of the capillary tublng 54 and enter the cavity 22 of the container 20 or 20.
  • a quantity of gas such as air, may be forced through the conduit 66.
  • Packing may be used to assure that the connection or coupling between the coupler 68 and the free end of the standard 50 is completely tight, this taking the form of a small O-ring 72 set into a suitable groove formed on the interior of the hood 70.
  • the coupler 68 may be built into a plunger which depends from a reagent source that is provided with a metering device and some automatic means for injecting the diluent, as will be explained hereinafter.
  • the arrangement for introduction of liquid into the container after the section of capillary tubing has been placed in the barrel 52 which is shown in FIG. 6 requires no special form of the central standard 50. It may be a simple cut section of commercially available plastic tubing set into the recess 46.
  • the container is molded in one piece, either in a simple form as container 20' or in the more complex form of container 20, both with a recess.
  • the piece of plastic tubing should be stiff enough to enable it to be pressed into the recess, and will remain in place without the need for cementing. Glass can also be inserted in this same manner. Obviously, it would be best to mold the standard in the container in one step, but this cannot be done economically at the present time due to complexity of molds required.
  • FIG. 7 a modified form of the standard is shown.
  • the standard 50' differs from those previously described in that it has a flared mouth formed at 51.
  • the container 20" may be identical to the other two described.
  • This flared mouth provides a flared pilot entrance 53 which can receive a tapered male coupler member 70 which is on the end of a conduit 66 that leads diluent to the container 20".
  • the entrance recess 53 pilots the coupler member 70 and seats it.
  • the tapered fit may be enhanced by suitable grinding or by other techniques to guaranty accurate engagement.
  • flared mouth 51 Another advantage of the flared mouth 51 is that it enables more facile introduction of the section of capillary tubing into the standard. In other words, it serves as a pilot for this function as well. In the case of handling a large number of containers and inserting sections of capillary tubing into each, providing a pilot formation enables this to be done by machinery more readily, as will be explained.
  • the well 48 is formed as a lateral branch of the recess 46, but is lower than the recess so that liquid will freely pass from the barrel 52 into the well.
  • the dimensions are chosen so that the bottom floor 47 of the recess 46 will have the well 48 intersect only a portion thereof, providing suflicient sup port for the bottom end of the standard and the capillary tube while still leaving passageway for the liquid.
  • FIG. 8 a sectional view is illustrated on a large scale looking up through the well 48.
  • radial feet 80 are molded in the bottom of the cavity 22 of the container, such as container 20, or 20".
  • the top surface of these feet may lie in a plane which in the previous structures would have defined the bottom level 24 of the cavity 22, although in this case, since the resulting quandrant shaped wells 82 have a much greater bottom area than the top surfaces of the feet 80, this forms the practical bottom of the container.
  • the feet 80 do not meet at the center of the container, but instead are shortened to provide a central generally square area 84 freely communicating with the wells 84.
  • the radially inner tips of the feet 80 are stepped at 86 to provide a seat for the bottom end of the standard, equivalent to the recess 46 previously described. In this case, there are four points for support of the lower axial end of the standard 50. This is not shown in FIG. 9, but it is shown in FIG. 10.
  • the length of the feet 80 is chosen so that the steps 86 extend radially inward a sufficient distance to provide support for the axial end of the capillary tubing 54 when inserted and moved to the bottom of the barrel 52 Without obstructing its bore. In FIG.
  • a plurality of containers 20, 20' or 20" is mounted on a conveyor or rack 90 indexed by the structure described as lugs 64 on the conveyor cooperating with notches 62 in the containers.
  • the structure generally illustrated at 92 may be some form of positioning device or holder to be used in lieu of or in addition to the indexing means.
  • the purpose of this illustration is to show how a plurality of sections of capillary tubing 54 of suitable length (and hence holding predetermined volumes of entrained liquid respectively) may be inserted into the standards of a plurality of containers passing relative to an injecting device.
  • the device is indicated at 94 and it feeds sections of capillary tubing one at a time into the standards of passing containers.
  • the station is properly indexed relative to the passing conveyor 90 and the containers carried on the conveyor. These will stop at the station long enough to receive their respective sections of tubing and then pass on.
  • a structure such as illustrated in FIG. 7 is of great advantage in this case because it pilots the insertion of the section of capillary tubing and hence indexing of the movement of the conveyor 90 relative to the insertion station and the apparatus 94 need not be so accurate.
  • a predetermined number of containers may receive sections of tubing containing raw liquid from the same source for a variety of tests, or the sections may each be from a different source. It is important to ensure identification of the source with the container carrying the raw sample derived respectively therefrom.
  • FIG. 12 there is illustrated a form of apparatus in which the sample containers 20 are substantially as shown in FIGS. 1 through 4, each being secured to a post 44 carried on a rack 96.
  • Each has an identification card 38 depending from its holder to move relative to printing apparatus when tested, as explained in said co-pending sample identification application. Accordingly, there will be information carried on the cards in the form of indicia, both human and machine sensible.
  • a rack 96 will contain samples from the same or several sources, but in each case, the container is readily identifiable both as to source and as to the type of test to be made.
  • the rack is arranged in a structure which moves the rack relative to a plurality of stations, with a supply of different reagent at each station. It is required that the proper reagent be introduced into each sample container in accordance with the test performed.
  • Each cylinder may be a part of a liquid injecting apparatus, not much dilferent from those to be found in bottle filling machines of known construction, but energized according to a system described.
  • the machines connect with sources of reagent of different variety (not shown) and in operation will have a tube carrying a coupler descend to engage the free end of the standard which is in the container suitably located below the coupler.
  • the couplers are shown at 68 on the bottom ends of reciprocable plungers 103. The center plunger is down, but the other two are still retracted.
  • each station has, in addition to its liquid filling mechanism, a reader 104 which is sensible to the indicia carried on the identification cards 38.
  • Each reader is constructed to respond only to the test description which requires the reagent which can be introduced at that station. Thus, unless an identification card carries the particular indicia to which the reader is responsive, nothing occurs at the station, irrespective of whether the rack 96 is moving or stationary. When a test description produces a response in the reader, the movement of the rack is stopped with the container indexed at the station controlled by the reader.
  • the liquid filling machine operates to fill the container, the plunger bringing the coupler 68 down to the standard and forcing the liquid through the barrel 52 of the standard and thereby producing the proper diluted testing sample in the container.
  • the plunger retracts the coupler 68, and the rack is free to move further.
  • Racks may be arranged to move past single or plural stations. The positive identification of samples and sources makes it unnecessary to install the containers on the racks 96 in any special order.
  • a fluid sample container for receiving therein a section of capillary tubing to enable diluent to be introduced through the bore of the capillary tubing into the container, comprising:
  • a container as claimed in claim 1 in which there are means for mounting said standard comprising a recess in the bottom of the container and the bottom end of the standard being secured in said recess, and said liquid passage means comprise at least one well opening to the interior of said recess and to said cavity.
