MEDIC INAL CARRYING TUBE Filed July 23, 1938 III Patented Jan. 3, 1939 UNITED starts PATENT OFFIQE 2 Claims.
The present invention is related to means for conveniently carrying, in a single structure, separated drugs and solvents to form an inherently stable solution when united, and to facilitate the union of the drugs and the solvent immediately prior to the use of the solution by surgeons or physicians.
It is an object of the invention to provide a structure to carry pills, powders, or the like in sealed relation to the atmosphere, and at the same time to carry a solvent sealed against contamination, while providing means of eminent simplicity to facilitate the union of the powders and the solvent under sealed conditions immediately prior to the use of the solution by physicians.
It is a further object of the invention to provide means adapted for use with phials, test tubes, or the like, for carrying a medicament in sealed relation to the atmosphere and contaminating in fluences, and to dispense the medicament into a solvent under sealed conditions.
It is a further object of the invention to provide a drug or solvent carrier to facilitate the union of the drug and solvent under sealed conditions when desired, and to facilitate the use of a hypodermic syringe to remove the solution under sealed conditions.
The above, other, and further objects of the invention will be apparent from the following description and accompanying drawing.
Figure .1 shows in elevation a medicinal carrier in its normal condition.
Figure 2 shows in elevation the carrier of Figure 1 with parts turned in alined relation.
Figure 3 is a perspective view of an element of the carrier of Figure 1.
Figure 4 is a perspective View of an element of the carrier of Figure 1.
Figure 5 is an enlarged sectional view of parts of the carrier of Figure 1, with parts broken.
Figure 6 is a perspective view of a modified form of a part of the carrier of Figure 1.
In Figure 1 there is illustrated a medicinal carrier comprising a tube 90 to carry a solvent, a slotted plug I I provided with a slot l2, and a stopper 13 provided with an upper slot is terminating at its lower end in a partition l5, and with a lower slot H6 in alined relation to the upper slot. The partition is provided with an aperture H, and a diaphragm I8 is positioned on the partition to provide a closure for the aperture. The material of the diaphragm is such that it may be readily pierced by the needle of a hypodermic syringe, but effectively closes the aperture I! when the needle is removed.
The stopper I3 is suitably shaped, and is formed of a material such that it snugly engages the inner face of the wall of the tube while permitting rotation of the stopper from the position shown in Figure 1 to that shown in Figure 2.
The carrier is shown in its normal assembled relation in Figure 1, so that powders, pills, or the a like are carried in the lower slot [6, with the partition i5 and the plug ll defining a chamber I9 therewith sealed against outside influences.
When the stopper i3 is turned to the position shown in Figure 2, it will be obvious that the pills, powders, or the like, carried in the chamber l9 will now fall into the solvent to provide a solution. When the pills, or the like, have been dissolved in the solvent, the needle 20 of a hypodermic syringe 2| may be inserted through the pierceable diaphragm E8 to withdraw the solution.
The walls 22, which define the slot l4, provide guide means for the body of the syringe, and the partition ll provides a stop, so that the syringe may be readily and surely applied to the carrier even when the physician has to contend with such unfavorable conditions as poor light, bad weather, and awkward working posture in his practice.
When a part of the solution has been withdrawn from the tube ill, the stopper I3 may be again turned to the position shown in Figure 1 to seal the contents of the tube.
A modified form of stopper 23 is shown in Figure 6. This stopper is provided with a recess 24 adapted to cooperate with the plug II in providing a chamber for pills, powders, or the like, in the manner described in connection with the stopper H3. The stopper 23 is adapted for conditions in which it is turned to the position shown in Figure 2, and is then removed to permit the solution to be poured as in the dressing of wounds, etc. When a part of the solution has been poured, the stopper may be reinserted in the tube to seal the contents of the tube in the manner described in connection with the stopper l3.
The slot. i2 provides an opening adapted to facilitate the pouring of the solution under con-- trolled conditions when the stopper 23 is removed, and prevents accidental rapid spilling of the contents.
I am aware that many changes may be made and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I, therefore, do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art.
I claim as my invention:
1. In combination, a medicinal carrying means comprising a phial, a plug entered in said phial and near the upper end thereof, said plug being provided with means defining a side slot, and a stopper entered in said phial to engage said plug, said stopper being provided with a side slot having a partition interposed therein and between the ends thereof, said partition having an aperture therein normally closed by a resilient diaphragm.
2. In a medicinal carrying means which includes a phial to receive a solvent for a medicament, means to provide a closure for said phial and to cooperate therewith to provide a chamber for a medicament, said means comprising a plug provided with a side slot, and a stopper provided with a side slot having a partition interposed therein and between the ends thereof, said partition having an aperture therein normally closed RALPH W.
