April 2, 1957 1. GREENSPAN BLOOD PLASMA BOTTLE Filed March 16, 1956 garner/575 M @merza affawvze gxa United States Patent BLOOD PLASMA BOTTLE Irving Greenspan, Skokie, Ill.
Application March 16, 1956, Serial No. 572,035
9 Claims. (Cl. 128-272) This invention relates generally to a container for perishable materials and more particularly is concerned with the construction of a container for blood plasma which is adapted to be used for direct application quickly and without difficulty.
Blood plasma is usually dried, and mixed with water just prior to administration, and considerable difliculty has accompanied the use of the containers which are known, especially for field application. The plasma is perishable, and hence it and a container of water are furnished as two separate parts of a kit. The plasma is in powdered form and packed in vacuum and the water is sterile. The attendant is furnished with a double ended hollow needle. One end must first be inserted into the water bottle cap, and the water bottle is then picked up and the opposite end of the needle inserted into the plasma bottle so that the vacuum in the plasma bottle draws the water through the hollow needle and into contact with the dried plasma to become hydrated. Thereafter, the water bottle is removed and a tube with administering end is attached to the needle now protruding from the plasma bottle. The liquid then flows either by gravity, or through the use of a pump fitted to the administering tube, to the blood vessel of the patient.
The difficulties attendant upon the use of the kit described are manifold:
1. In haste, often the needle will first be inserted into the plasma bottle, whereupon the vacuum is lost and there is no sterile way of admixing the dried plasma and water, and even if there were some way of introducing the water into the plasma bottle, the air sucked in when the vacuum is broken may well have contaminated the plasma. Thus there has been in the past tremendous waste due to errors of personnel and this had been particularly serious in combat, where the attendant may not have much skill along these lines.
2. Bottle breakage is a cause of considerable loss.
3. The kit contains two bottles, and hence is heavy and takes up considerable space.
4. In forced administration, the pump must be fitted to the administering tube and operated continuously by the attendant because small size of the conduit in the needle limits the rate of flow.
This invention alleviates and eliminates the disadvantages of previous methods of administering blood plasma and the principal object of the invention is directed to provision of a structure for a plasma bottle which will eliminate and positively prevent the error of puncturing the wrong bottle with its attendant waste; the provision of a structure which is unbreakable; the provision of a structure for a plasma bottle which is a single unit, light in weight and of small volume; the provision of a plasma bottle with which plasma may be forcibly administered without the need for pumps or other fittings.
Many other objects of the invention will appear as the description proceeds in connection with which I have illustrated a preferred embodiment from an examination ice of which, in connection with the explanation, the invention should be fully understood and appreciated.
In the drawing:
Fig. 1 is a side elevational view of a plasma bottle constructed in accordance with the invention.
Fig. 2 is a sectional view taken through the same along its axis.
3 is a sectional view through the plug of the bottle on an enlarged scale.
Fig. 4 is a fragmentary sectional view through the bottle showing same during use.
Generally, the invention consists of a bottle of some flexible material, such as polyethylene, having two compartments, separated by a wall which is normally plugged during transportation of the bottle. The dried plasma is in one compartment, and sterile water in the other, if desired. The plasma compartment is unplugged when it is desired to use the same, and the plug becomes the cap for the bottle, such that when inverted the needle of the administering tube may be inserted through the plug into the bottle. After unplugging the plasma compartment and closing off the end of the bottle, the bottle is shaken to dissolve the plasma. When forced feeding is desired, the bottle is squeezed and its collapse increases the pressure of the flow of plasma.
Referring now to the drawing, the bottle is designated by the reference character 10, and it will be seen that same is formed in any conventional shape, such as for example, having a cylindrical configuration providing cylindrical side wall 12 with a bottom wall 14 closing off the bottle, and an upper neck 16 having an internally threaded mouth 18 adapted to be closed off by a cap 2t) with a male threaded portion 22. The bottle has a central diaphragm or wall 24 provided with a central reenforced threaded opening 26 coaxial with the mouth 18 and preferably of smaller diameter.
The wall 24 thus forms the interior of the bottle 10 into two compartments, the upper or water compartment 28 and the lower or plasma compartment 30. Obviously when used, as in Fig. 4, the compartments are inverted.
The cap 22 has a depending rod 32 of some inert material such as plastic, which telescopically engages with another rod 34 at the bottom of which is fastened a plug 36. If desired, a slot and pin connection may be provided to prevent separation of rods 32 and 34, but relatively tight frictional engagement is suflicient. The configuration of the telescoping members 32 and 34 is such that rotation of the cap 20 imparts rotation to the plug 36, irrespective of the positions of the cap and plug one relative the other. The plug 36 has an upper threaded part 38 which is of a size to engage with the threads of the mouth 18, and a lower threaded part 40 which is of a size to threadedly engage with the threads of the opening 26. The rod 34 is frictionally engaged in a suitable recess 42 in the plug 36 and the upper end of the rod 32 is fixed to the cap 20. There is a diaphragm 44 in the plug 36 to enable a needle 46 on the end of an administering tube 48 to be inserted therein as shown in Fig. 4 when the bottle 10 is used.
The bottle 10 is preferably formed of polyethylene or similar flexible resilient material, and while shown as an integral structure may be composite, that is-made up of two parts welded or cemented together to eliminate the need for complicated moulding procedures or coring. Any suitable means for supporting the bottle 10 inverted may be used, such as for example, a tape 50 secured to the side of the bottle by cement or the like provided with a grommet 52 or the like.
In filling the bottle, first the dried plasma. is disposed in the compartment 30. The assembled plug 36, cap 20 and the connecting rods 32 and 34, is then manipulated so that the plug 36 is screwed through the mouth 18,
Patented Apr. 2, 1957 greases after which the plug is lowered and part as is tightly screwed into the threaded opening as, thereby closing off the plasma in the lower compartment. Thereafter water may be introduced into the compartment 28 by any suitable means, and the cap 2% tightly screwed home. This process may readily be done under sterile conditions in the manufacturing laboratory, and if required, the completed package may be subjected to heat for sterilizing purposes. The upper compartment may be left empty if facilities to provide sterile water available at the place of use.
,In use, the bottle is prepared by first unscrewing the cap 20. While this is being done, the plug 36 is being removed from the opening 26. The plug is thereafter lifted and screwed into the mouth 18 from the bottom thereof, as shown in Fig. 4. The cap 12 and rods 32; and 34 are then pulled away from the plug 36. The bottle it) may then be shaken to dissolve all of the plasma. Thereafter it is inverted into position, the needle 45 inserted into the diaphragm 44 and the plasma immediately flows through the tube 48 to the patient. If pressure is desired, the attendant merely grasps the bottle 1d and squeezes the same and forces the liquid plasma through the tube 48. Any suitable valve arrangement may be used to admit air into the bottle as the liquid 54 is emptied.
Obviously where the bottle MD is made of an inflexible material, all of the advantages of the invention accrue with the exception of the advantage of being able to apply force by merely squeezing the bottle.
It is believed that the invention has sui'liciently been described to enable an understanding thereof, but it is desired to point out that considerable variation is possible without departing from the spirit and scope thereof as defined in the appended claims.
