Application December 16, 1940, Serial No. 370,269

5 Claims.

This invention relates to a blood transfusion device in which av single container is used, and to a penetrable closure for the container having a guide member.

Among the objects of my invention is to provide a blood transfusion device in which a single container having a partial vacuum is used in combination with an insertable, withdrawal means having a valve control, to supply a single container for use in receiving, infusing, storing and dispensing in blood transfusions, to create a penetrable closure for the container, having a guide .means visible, from the outside of the container which will prevent broken or 4damaged needles, and such other objects, advantages and capabilities as will later more fully appear and which are inherently possessed by my invention.

While I have shown in the accompanying drawing a preferred form of my invention, yet I wish it understood that the same is susceptible of modilication and change without departing from the spirit of my invention.

Referring to the drawing, Fig 1 is a perspective able member has a top portion 56 whichbears down against the top of plate I5, and a cut-out portion 5l forming a grip 58 with a substantially central aperture 59. There are spacedy scores 60' extending across top portion 56 and side portions 6I to aid in removal.

ber 20. f

In cooperation with saidcontainer ,I providea valve structure 2| of any suitable construction, but preferably that disclosed in my co-pending application, Serial Number` 322,368, now Patentl Number 2,226,538. l Attached to the valve 2| is a needle 32. Also attached to valve 2| is a tube 26,

, on the other end of which is removably attached View of my container; Fig. 2 is a detailed sectional view of the top of the container; Fig. 3 is a sectional view of the valve construction in combination with vthe container; Fig. 4 is an enlarged detailed view of my cap and stub; Fig. 5 isan enlarged detailed view of my stopper and Fig. 6 is an enlarged detailed perspective view of my removable closure member.

The embodiment selected to illustrate my invention comprises a container I0 having a hollow body portion I| -partially lled with an anticoagulant solution such as a solution of sodium citrate 21/% in physiological solution of sodium chloride. There is a partial vacuum in the container |0, the open top I2 of which is sealed by a closure I3.

The closure I3 comprises a stopper 5|! of rubber, composition or other suitable material. The stopper 50 has a lower central portion 5I adapted to enter the open top I2 of the container I8, and an upper portion 52.With flanges 53 resting on top of the walls of the open top of container I0.

A plate I5 of metal or other suitable material is positioned with its bottom portion positioned against upper portion 52 .of stopper 50. A stub II is substantially centrally attached-to plate I5. An opening I8 extends vertically through stub I1 and plate I5.

A removable member 20 of soft metal or the like has side portions with screw threads 54 to engage screw threads 55 on the side walls of the container I0 adjacent its open top IZ. Remova transfusion needle 34 adapted for insertion into the vein of a donor.

In the use of my blood transfusion devicejmy container I0 containing an anti-coagulant such as a solution of sodium citrate, 21/2% inphysiological sodium chloride solution, and having a partial vacuum sealed with a closure having a penetrable top, is available. With the valve in closed position I unscrew cap from stub I'I and insert the valve needle 32 `through opening I8 in stub I'I and stopper 50 into the container I 0'.

'I'he transfusion needle 3 4 is theninsertedlinto; the -donors vein and the valve 2| is slowlyV opened. The vacuum in the container by equalvizing pressure causes the blood to flow from the transfusion needle 34 through the tubing 26 and valve structure 2| into the container I0. The solution in the container prevents coagulation of the blood. swirling may be desirable.

The valve needle 32 may be withdrawn and the container l0 sealed by screwing cap 65 into tight engagement with stub I'I and washer 62, thus `forming a hermetic seal. The blood may then be refrigerated and stored or transported in the sealed container. l I

The same container I6 maythen upon removal of cap 65, removable member 20, plate I5 and stopper 56 receive a suitable air providing dispensing cap or other dispensing apparatus and'beA 4placed in a dispensing position by turning the container I8 upside down and attaching its loop 36 to a suitable standard. The blood in the container I0 may then be passed through the dispensing cap or other dispensing apparatus to a suitable tube and dispensing needle to the recipent. as shown in my cfa-pending application Se Y OI Venous pressure.

may bein thesecond bottle;

,Y rial Number 322,368, now Patent Number My container I0 is thus usedthroughout the withdrawal, storing, transporting and dispensing of the blood. 'Ihere is no change from one vcontainer to another, to involve the problems of` contamination, lossr and extra apparatus.

I may also provide a removing'member 66 adhering or otherwise Vattached to the upper surface 52 'of the stopper 50. Said removing member 66 has a tab 61 on its outer edge. Said tab 61 is positioned to extend past the outer edge of plate I5 and Vis folded on top of plate I5 so as to be i visible through cut-out portion 51 in removable member 20. The removing member 66 `also has a central aperture 68 so Vas to not interfere with .Y the passage of valve neeedle 32; When closure. I3

is to be removed for the attachment ,off Va dise pensing cap, the user may by means of `tabl'l,V quickly remove vstopper 50 without danger of contamination to the open top I2 of V container I0 bycontact therewith. Y

Iii-some instances mygcontainer o trable closure may contain no partial vacuum as the blood may be drawn in by virtue of gravity vI may use a centrifuge blood to gather the empty gathering bottle thereto by plunginga long needle through the penetrable,closure'intothe rst-bottle lto the bottom level of the plasma. 1 YThis needle isconnected by means orf'tubing and. ka valve to the second bottle which is Yunder high: vacuum but which contains no anti-coagulant.
