Field of the Invention This invention relates to capillary tube sealant trays.
2. Description of the Prior Art Capillary tubes are used for collecting blood samples to be centrifuged. Two specimens in separate capillary tubes are collected from each patient and one end of each tube is then sealed by forcing it into a mass of sealing compound and leaving it in the compound until it is ready to be centrifuged. Normally a number of pairs of specimens from different patients will be run at the same time creating a problem of identification of the tubes in the sealing compound especially if the tubes are in close proximity to each other. Identification becomes increasingly more difficult as the tray full .of
compound is being filled with the capillary tubes. When a loaded tray of sealing compound is accidentally dropped, identification can become impossible and often even without dropping the tubes may fall out or be moved from their original location due to inadequate tube retention.
SUMMARY OF THE INVENTION The present invention provides a new and useful capillary tube sealant tray. The tray contains a supply of sealant material of putty-like consistency and has a laterally extending portion of the tray which is provided with a system for holding capillary tubes in identifiable positions. Usually the holding system will include a pair of tube receivers adjacent each identified position for holding and identifying a pair of specimens collected from a single patient.
In a preferred form the tray will hold sealed duplicate capillary tubes in an area separated from the work area and in a positively identifiable manner, leaving the work area free. Because the capillary tubes are held in a printed and clearly identifiable area, the possibility of specimen-patient mix-up has been eliminated. A large tab can be provided at one end of the tray, useful for receiving advertising matter, as a convenient handle for accident-free transporting of the tray. Further, in the preferred form, the effective base or footing area of the tray is increased by the bottom surfaces of the laterally extending holding system minimizing the possibility of tray tippage.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a capillary tube sealant tray showing positions of the capillary tubes and the condition of the mass of sealant in the tray after having used the tray to seal a plurality of capillary tubes;
' FIG. 2 is an enlarged top plan view of the tray shown in FIG. 1;
FIG. 3 is an enlarged section alongline.2.-2 of FIG. 2, showing details of a capillary tube receiver;
FIG. 4 is a fragmentary side view of the tray shown in FIG. 1; and
FIG. 5 is an enlarged end view of the tray shown in FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENT As seen in FIG. 1 the preferred form of the invention is a tray indicated generally by reference numeral 12 which is an integral one-piece molded plastic body. The tray 12 has a container portion 14 and a laterally extending capillary tube holding and identification system in the form of a top lip flange 16 having vertically extending tube holder cavities 18 formed as depressions in the lip flange 16. The tube holder cavities 18 are formed in two opposite lateral sides or portions of the lip flange 16 as depressions therein and pairs of the cavities 18 are interconnected by canals 20 which extend outwardly generally perpendicular to the side edges of the container portion 14. The cavities 18 can be considered as enlargements in the canals 20 and it will be noted that the canals 20 on each side of the tray are generally parallel to each other and each includes two of the enlargements or cavities 18 The side walls of the canals 20 are formed by lands 22b, 22a and 22c respectively. The portion of the canal 20 formed by lands 22a connects the innermost cavity 18 with the container portion 14 while the lands 22c form a portion of the canal 20 extending beyond the outer cavity 18 in each pair. The lands 22b form a portion of canal 20 interconnecting the cavities 18 of each pair. Each pair of cavities l8 and its corresponding canal 20 is identified by identification marks 24 in the form of a different number for each cavity pair.
Within the container portion 14 there is provided a mass of putty-like capillary tube sealant material 26. As best seen in FIG. 1, a plurality of capillary tubes, each identified by reference numeral 28, can be sealed by forcing the end of each tube into the plastic mass of sealant 26, removing the tube and placing the tube vertically in a cavity 18. Each tube pair from a single patient is placed in a corresponding identified pair of cavities 18' associated with the same canal 20, to properly separate and identify the pairs of the capillary tubes.
As best seen in FIGS. 1, 4 and 5, the bottom wallsof the canals 20 and cavities 18 extend outwardly from the bottom wall of container portion I4, generally coplanar therewith, to form a plurality of laterally extending footings or support ribs 30 which increase the effective lateral support area of the tray and minimize lateral tipping. As an additional feature, shown in FIGS. 1, 2 and 3, there is provided a handle-tab 32 as a' portion of flange 16 at one end of the container portion 14. The handle-tab 32 is useful in graspingand transporting the tray and is also useful for receiving advertising matter or other indicia.
' Y The device of this invention can easily be molded as an integral plastic member. It is advantageously useful for receiving a mass of sealing compound in the container portion and can be. used to seal ends of blood samples containing capillary tubes so they can be centrifuged; The device is particularly adapted to hold and identify two separate capillary tubesfrom each patient. The trays structure minimizes spillage and droppage from the tray.
Although there has been shown in the drawings and has been described herein in detail one specific embodiment of the invention, it is to be understood that the invention is susceptible of embodiment in many different forms and the description of the one specific emlimit the spirit and scope of the invention.
I'claim:
1. A tray for use in sealing the end of capillary tubes which comprises a container portion of the tray for containing a supply of sealing composition, and a laterally extending top flange including a plurality of depressed canals generally parallel to each other and extending laterally from the tray portion, each of said canals including at least one vertically extending enlargement for separately receiving and holding a capillary tube.
2. The tray of claim 1 wherein a separate and different number is printed on the top flange adjacent each canal for specifically identifying each canal.
3. The tray of claim 1 wherein said canals extend at two opposite sides of the container portion.
4. The tray of claim 1 wherein said canals have walls integral with the top flange and define laterally extending support ribs on the bottom of the top flange extending down to the plane of the tray bottom for minimizing lateral tipping of the tray.
5. The tray of claim 4 wherein said canals extend laterally outwardly from two opposite sides of the container portion.
6. vThe tray of claim 1 wherein each of said canals includes two vertically extending enlargements for separately receiving and holding two capillary tubes.
7. The tray of claim 6 wherein each canal extends between its two enlargements and laterally beyond the second or most lateral enlargement.
