AMPUL.

Application filed January 5, 1926.

This invention relates to ampules.

The general object of the invention is to providea dual ampul wherein the two compartments serve as holders for drugs and drug vehicles.

A specific object of the invention is to provide an ampul Comprising two parts, and wherein the parts are separated by a partition made of the same material as the ampul.

Another object of the invention is to'provide a dual ampul wherein one part is exhausted and whercin'the parts are separated from each other by a frangible glass partition.

Another object of the invention is to provide an improved method of making ampules. 7

Other objects 01 the invention will be apparent from. the following description taken in connection with the accompanying drawings, wherein:

Fig. 1 is a transverse section of the completed ampul;

Fig. 2 is a-tube from which the ampul is made;

Fig. 3 shows one body portion made from the tube and having a neck drawn thereon;

Fig. 1 shows the other body portion of the ampul with the neck drawn thereon;

Fig. 5 shows a glass tube from which the connecting neck is formed;

Fig. 6 is a View showing the partition neck;

Fig. 7 is a view showing the connecting neck attached to one of the body portions;

Fig. 8 is a view showing the partition neck attached to one of the body portions;

Fig. 9 is a view showing the two connected body portions;

Fig. 10 is a view showing a drug in one of the body portions and. the means for hermetically sealing that body portion;

Fig. 11 is a view showing a vehicle in the other body portion; and

Fig. 12 is a transverse section of the ampul showing the connecting neck frac-- tured and the vehicle mixed with the drug.

Referring to the drawing by reference characters, I have shown an ampul embodying the features of my invention at 10. This ampul comprises dual compartments 11 and 12. In manufacturing my ampul I first take a glass tube 1 1 as shown in Fig. 2 and heat and blow this tube into the shape Serial No. 79,314.

shown in Fig. 3 where it will be noted that the tube has a neck 15 which is provided with a bulbous portion 16 at one end and atthe other end has a neck 17. In a similar manner I make another part 18 which has a neck 19 thereon at one end and has another neck 20 at the other end.

I also take a glass tube 21 as shown in Fig. 5 and use this tube as a connecting neck. A partition forming neck is shown at 22 in Fig. 6. This neck is provided with a bulbous portion 23 for a purpose to be presently described.

After the parts are so made they are assembled by first securing the connecting neck 21 to the tube 1 1 and by securing the partition neck 22 to the tube 18. hen this is done, a gauze filter 25 is placed in the neck portion 21 and the two parts are brought together and united, with the neck 21 fused to the end of the body 18. The ampul thus completed may be used for any desired purpose.

In the following descrintionI will describe one specific use of the ampul wherein the compartment 11 in the top portion 14; has a drug 26 placed therein. A rubber tube 27 of a vacuum producing machine is then placed over the bulbous portion 16 and the compartment 11 is exhausted. The compartment 11 is then sealed as at 28 so that the drug 26 will be secured in the exhausted compartment. The other compartment 12 in the tube 18 is then filled with a vehicle 29 in which the drug 26 is adapted to be dissolved. This done, the conipartn'ient 29 is sealed as at 30 and the ampul is complete.

Any specific drug and any vehicle suitable for making a solution. with that drug may be used if desired.

In using the ampul I first nick the end of the ampul as at and break off the tip, I may then insert a probe 36 through the opening and force it against the bulbous portion 23 on the partition neck 22 thereby breaking the end of the bulbous portion. The gauze filter will catch the fragments of glass while the vehicle will be drawn through the neck 22 due to the vacuum and will flow into the compartment 11 where it will mingle with the drug to form a solution. This solution may be used by inserting a hypodermic needle through the upper compartment 12 and drawing out the liquid or the lower end of the compartment 12 may be nicked and broken off.

Other methods of using the ampul will suggest themselves and it will be apparent from my description that the ampul is adapted for wide use and general application.

Having thus described my invention, 1 claim:

1. An ampul comprising a glass body having a neck at each end and having a glass partition intermediate the ends thereof, said partition forming two compartments, one of I said compartments being exhausted and having a drug therein and the other compartment having a vehicle therein for the drug.

2. An ampul comprising an elongated tubular body having a restricted central. portion therein, a partition forming neck within said restricted portion, said partition neck having a frangible portion thereon to provide two compartments, one of said com partments formed by said partition neck having a drug therein and the other compartment having a vehicle therein for the dru 3. An ampul comprising two portions having a connecting member uniting said portions, theends of said ampul being closed, a partition having a hollow portion thereon and fitted within said connecting neck, a gauze filter engaging the hollow portion of the partition neck and also engaging the connecting neck, a drug in one of the compartments and a vehicle in the other compartment, said drug holding compartment being exhausted.

4-. An ampul comprising two tubular portions having a connecting neck uniting said portions to form an ampul, the ends of said ampul being closed, a partition in said ampul, a gauze filter engaging the partition and also engaging the connecting neck, a drug in one of the compartments and a vehicle in the other compartment, said drug holding compartment being exhausted.

5. An ampul comprising an elongated tubular body having a restricted central portion therein, a restricted neck at each end of said body, a neck within said restricted portion, said neck having a bulbous portion thereon and integral therewith, a gauze til ter surrounding said bulbous portion, one of the compartments formed by said partition neck being exhausted and having a drug therein and the other compartment having a vehicle therein for the drug.

6. An ampul comprising two hollow portions having a connecting neck uniting said portions, the ends of said ampul being closed, a frangible partition separating said two hollow portions and a filter body associated with said partition and adapted to retain particles broken when the partition is fractured.

In testimony whereof, I hereunto aflix my signature.
