DEVICE FOR FILLING BLOOD CONTAINERS Filed Jan. 30, 1961 INVENTOR. PAUL WINCHELL.

ATTORNEY United States Patent 3,Bd2,tl8-5 DEVICE FOR FILLlNG EEJOOD CONTAINERS Paul Winchell, Whitestone, N.Y., assignor to Chelwin Productions, Inc, New York, N.Y., a corporation oi New York Filed Jan. 30, I961, Ser. No. 85,863 6 Qlaims. (Cl. 141-390) This invention concerns a device for holding a plastic blood container while filling it and for insuring that a measured amount of blood flows into the container.

According to the invention, there is provided a holder for a blood container. The holder includes two hinged dished plates preformed to the shape of a plastic bag filled with the desired amount of whole blood or blood plasma. The plates are formed of transparent, rigid material, such as glass, or a suitable plastic, such as acrylic, Lucite and the like. The plates are provided with rectangular, frame-like margins which abut when the holder is closed. Studs are formed on the margin of one plate which fit into corresponding mating recesses or holes in the other plate. Quick detachable clamping members are provided on the outer edges of the plates to lock the holder in a closed position. On each plate is marked or etched a graduated scale for measuring the quantity of blood in the container. The container is a flexible plastic bag formed of polyethylene or the like. It has tubes connected to one end by which it may be filled or emptied. This container is transparent or substantially so, so that the quantity of blood in the container is visible through the walls of the container and holder. The container has a rectangular margin aper tured to engage the studs of the holder.

The container is placed in the holder in an empty flat condition. A quantity of blood then flows into the container through the tube which extends out through the holder. The scales marked on the plates indicate the quantity of blood in the container. The device has particular utility when a donor is contributing blood to a blood bank or the like. The blood flows from the donor under some pressure through the tube to the container. The holder in which the container is supported insures that the flexible container cannot expand more than a redetermined amount and that the quantity of blood in the container is exactly that indicated by the scales marked on the sides of the holder.

It is therefore a principal object to provide a holder for a flexible blood container which limits expansion of the container while being filled to a predetermined volume.

A further object is to provide a holder of the character described including two transparent, rigid dished plates hinged together at one end, the plates being provided with interfitting portions adapted to engage marginal edges of the container disposed therebetween, and with a quick detachable clamping means for holding the plates in a closed abutted position.

Another object is to provide a flexible plastic container for blood, the container having a connected filler tube and an outwardly extending flat margin with spaced holes for engaging studs of a holder of the character described.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

FIG. 1 is a side elevational view of a holder embodying my invention, in closed position on a blood container.

Patented July 3, 1962 FIG. 2 is an edgewise top plan view, taken on line 2-2 of FIG. 1.

FIG. 3 is an edgewise elevational view taken on line 3-3 of FIG. 1.

FIG. 4 is a vertical sectional view on an enlarged scale taken on line 44 of FIG. 1.

FIG. 5 is a perspective view of the holder per se in an open position.

FIG. 6 is a perspective view of a blood container adapted to be used with the invention and containing blood.

FIG. 7 is a cross-sectional view taken on line 7-7 of FIG. 6.

In FIGS. 1-5, there is shown a holder Il embodying the invention. The holder includes twoplates 12, 14 which are rectangular in form and of the same size. The plate 12 has a rectangular margin 16 and a dished center body portion 18 bulging outwardly of the plane of margin 16, but the body portion may be of other suitable shape. On the inner side of margin 16 there is a plurality of spaced radial studs 25 disposed all around the plate. A pair of cylindrical catch members 22 extend outwardly of opposite edges of the plate 12 adjacent one end. At its other end plate 12 has hinge elements 24. In the margin 16 at its upper end centrally of the body portion 18 there is a semicylindrical recess 26 extending across the margin. On the outer, convex side of the center body portion 18 there is ruled a plurality of lines 27 with indicia 28 indicating the quantity of blood E in a container 30 removably disposed in the holder.

Plate 14 has a rectangular margin 15 with dished center body portion 17 bulging outwardly of the plane of the margin. A plurality of holes 21 are formed in the margin 15 and spaced to receive the studs 29 on plate 12 when the holder is closed. Spring clamp members 23 are secured to or formed on opposite edges of the plate 14 to engage the catch members 22 on plate 12 when the holder is closed. Other suitable latching means besides the catch members 22 and clamps 23 may be used. Hinge elements 34 at the lower edge of plate 14 as viewed in FIG. 1 are engaged by pintles 35 with hinge elements 24 of plate 12. Other means of connection between the hinge elements may be used in place of pintles and in place of hinges. A semicylindrical recess 29 on the central upper edge of plate 14, as viewed in FIG. 1, is adapted to align with recess 26 to form a cylindrical passage for a tube 40 of the container 3%) Lines 31 and indicia 33 on the outer convex side of center body portion 17 of plate 14 constitute another scale for indicating the quantity of blood in container '30. A hook 45 may be secured to the upper marginal portion of one of the plates for supporting the holder in a vertical position when closed.

The container 3% as shown in FIGS. 4, 6 and 7, is a flexible transparent plastic bag, having a rectangular rame-like margin Stl corresponding in size to the margins 15 and 16 of the plates 1d and 12, respectively. Holes I9 are formed in the margin 56 in spaced positions corresponding to and registering with the spaced holes 21 and studs 29. The sides 41 of the bag which are sealed all around are generally rectangular and can expand when filled to the bulbous condition shown in FIGS. 4 and 7. A flexible rubber or plastic tube 4Q encloses three smaller tubes 41 which are secured to the bag at one end centrally thereof, and which communicate with the interior of the bag. The tube 40 may have a hypodermic type needle 54 inserted into its distal end as indicated in FIG. 6 for collecting from a donor the blood which fills the container and for dispensing the blood to a patient.

In FIGS. 1-4, the holder It is shown in a closed operative position with container 30 inserted therein and filled with blood B to a predetermined level measured by the snaaose 3 graduated scales on the sides of the holder. The tubes 41 pass through the opening formed by aligned recesses 26, 29.

In FIG. 5, the holder is shown open and ready to receive an empty plastic bag or container 30 in a flat condition. When the container is placed in the holder, the holes 19 in the bag are aligned with the holes 21 in the plate i The plate 12 is then swung closed and the studs 2h inserted through the holes 19 and the clamping members 22, 23 snapped closed togethed. As blood flows under pressure into the container, its sides expand, but the engaged edges of the container prevent the container from collapsing. The container is held securely and expands to fill the cavity defined by the spaced bulging sides 17, 13 of the plates. The holder limits expansion and insures that a desired measured amount of blood flows into the container. When filling is completed, the holder plates are snapped open and the filled container can be removed. A sample vial 58 containing a sample of the type of blood contained in the container 30 is preferably attached to the margin 59 of the container by means of an adhesive strip 60.

Aligned holes 16 and 15 are formed in the margins 16 and 15 of the plates 12 and 14, respectively, and a registering hole 50 in bag 30, whereby the holder lit with contained blood bag 3% may be hung upside down for transfusion operations.

There has thus been provided according to the invention, means for holding a flexible container while it is being filled. The marginal parts of the container cooperate with the marginal portions of the holder. The device is economical to manufacture. Its parts are easily sterilized. It is durable and simple to use.
