Description

BOTTLE FOR USE AS A SYRINGE ACCESSORY FIELD OF THE INVENTION This invention relates to a vial, or small vial, for containing medications, and mixtures, which may optionally serve as a syringe accessory.

BACKGROUND OF THE INVENTION It is known to use a syringe barrel as a prepackaged container for medicaments. The cylinders in these cases are of the type that are "moved in relation to a piston or piston that has an access way to the fluid through them." The cylinders or barrels usually have a hole that has a removable plug, and after separating The obturator, the open end is located on a plunger head for use.

OBJECTIVE OF THE INVENTION One objective of this invention is to provide a small vial or vial of the type described above. SUMMARY OF THE INVENTION In accordance with this invention, there is provided a vial containing a tubular cylinder of syringes closed at one end and open at the other, a stopper at the open end of the cylinder formed by a plunger head of a syringe , and a half valve in the cylinder, between the stopper and the closed end of the cylinder, the half valve, closed is normally and is operated to an open condition by the movement of the stopper inside the cylinder, and the valve means is slideable with the plunger head to the closed end of the cylinder. Preferably, the valve means is actuated by hydraulic pressure from a liquid, which is operated by the plug when it is pressed into the cylinder. Is the valve means provided to have a body that is slidable within u? obturating environment, the body having holes in it and being slidable from a closed position in which the holes are sealed by the sealing environment, to an open position where the holes in the body move beyond the sealing environment. Preferably, the body is a blind end tube with an outwardly extending annular skirt located at the open end of the tube, the tube having radial holes between the skirt and the blind end and an annular obturator around the blind end. The obturator may, otherwise, extend axially from the blind end, positioned from and around the tube to seal around the skirt.

BRIEF DESCRIPTION OF THE DRAWINGS Preferred embodiments of the invention are described below by way of example only, and with reference to the accompanying drawings, in which: Figures 1 to 3 are side views of cuts of a first embodiment of the invention in the stages of use; and Figures 4 to 5 are side views of cuts of a second embodiment of the invention, in use stages.

DETAILED DESCRIPTION OF THE DRAWINGS WITH REFERENCE Addendum With reference to Figures 1 to 3, a syringe barrel (1) is tubular with an open end (2) and a closed end (3). The cylinder has a plunger head (4) located at the open end, operating as a plug. The head of the plunger (4) has a blind access path (5) formed therein that runs from the inner end of the plunger where it is open, to the blind end facing the cylinder, at the outer end of the plunger. As will be appreciated by those skilled in the art, this plunger is depressed during use toward the sharp end of a needle hole as part of a syringe. The blind end of the plunger bore is drilled to create a path for the liquid to be discharged.

A valve means (10) is located in the cylinder between the head the plunger (4) and the closed end (2). The half valve divides the inside of the "cylinder in a chamber (11) closest to the head of the plunger, and a chamber (12) closer to the closed end (3) .The chamber (11) is filled with a liquid component, and the chamber "(12) is filled with a granular or powder component in a form that at least partially compressible, or that does not completely fill the camera (12). Normally, the liquid is a sterile solution that must be mixed with a powder medicine, usually an antibiotic. The valve means (10) has a body (11) in the form of a short tube with a blind end, having an open end (12) in front of the end cap (13). The wall (14) of the tube is separated from the walls' of the cylinder, and at the open end a skirt extending radically outwards (15) provides a sliding fit for the body of the valve means within the interior of the cylinder. At the blind end (13) the obturating means (16) is located in the shape of an O-ring. The O-ring is located in an obturating form around the blind end (13) .The radial holes (17 *) are located on the wall (14) between the skirt (15) and the installed position of the O-ring. During use, "the head the plunger (4) is compressed in the cylinder and the compressive force in the liquid in the chamber (11). ) pushes the half valve towards the second chamber and passes the 0 ring (16). The ring 0 has sufficient frictional coupling with the inside of the cylinder to cause it to pass the holes (17), thus connecting the two chambers through the radial holes (17). This position is shown in Figure 2. The cylinder can now be shaken slightly to ensure that the liquid and solid components are mixed properly. The cylinder is then connected to the syringe as already described, and the contents are injected. During the course of the injection, the head plunger moves towards the rear interior of the cylinder and in doing so engages with the body (11). The body (11) slides together with the head of the plunger to make butt contact with the inside of the closed end (3) of the cylinder, as indicated by the number (20) in figure 3. Now with reference to the figures 4 to 5, an alternative mode of a valve means is shown. In this embodiment, a valve means (30) has an obturating environment (31) in the form of a band of obturating material which is located around and extends between an open end (32) and a closed end (33) of a valve body (34). The valve body is similar in configuration to that described in relation to figures 1 to 3, with holes (35) in the walls of a short tube with blind end, and a skirt extending radially outwards (36) around the open end of the tube (32). The skirt, however, does not abut against the inside of the cylinder but is located against an axial end (37) of the sealing ring. The opposite axial end (40) of the sealing ring is radially thicker, extending inward to locate and seal around the blind end (33) of the body. The valve means fits within a syringe cylinder (50) having a plunger head (51) closing the open end thereof, and with an opposite closed end __ (52). The valve means divides the cylinder into two chambers, being a chamber (53), normally filled with liquid and located between the valve means and the head of the piston (51), and a chamber (54) between the valve means- and the end closed (53). The chamber (54) is usually provided with a solid material to mix it with the liquid in the chamber (53). During use, the head of the plunger (51) is compressed in the cylinder causing the liquid in the chamber (53) to actuate the valve body and slide it into the chamber (54) and make the -obturator means (37). In this position, the radial holes (35) move beyond the sealing means and allow the two chambers to communicate with each other.

As already described with reference to FIGS. 1 to 3, the cylinder is now stirred to mix the contents of the two chambers and connected to a syringe for discharge. It is possible to make variations to the above modalities without departing from the spirit and scope of the invention. A removable plug can be located on the head of the plunger to keep the head sterile before mixing, and the plunger can be replaced by a movable plug.
