Description:

This invention relates to therapeutic devices.

At the present time, certain treatments for a patient require the injection inter-muscularly or subcutaneously of certain medicines, usually in tablet form but which must be dissolved prior to injection. For instance, morphine and other palliatives must be dissolved. Usually this is done by placing the tablet in a spoon having water therein, which spoon is thereafter heated to pero1 mit dissolution of the tablet. A hypodermic syringe with its needle is then inserted into the liquid and the contents drawn within the syringe.

Medical doctors are constantly required to make injections and the procedure as outlined is ordinarily resorted to. However, the said procedure is inconvenient, and an object of the present invention is to provide a therapeutic device which is so arranged as to be compact, small, hold a solid burnable material, and likewise provided with a compartment adapted to receive the drug to be dissolved.

The device is so constituted and arranged that the combustible or burnable material is preferably in tablet form, and one of said tablets may be placed in said device, the water placed in the compartment arranged therefor in said device, together with the drug to be dissolved. When the combustible tablet is ignited, the chamber or compartment holding the water and the drug will be rapidly heated, whereupon the dissolved drug may be drawn within a hypodermic syringe.

Another object of the invention is to provide a device wherein a chamber or compartment member adapted to hold a dissolved drug is so constructed as to allow all the said liquid and drug to be withdrawn therefrom without substantial loss.

There is also provided by this device, suitable air circulation to control the combustion during a burning of the combustible material.

Further objects of the invention comprise a device of the character stated, which is simple of structure, inexpensive in cost of manufacture, sanitary, easily carried, always ready for use, and in which all necessary elements are combined in a unitary structure without the necessity of utilizing separate structures.

With the above and other objects in view, the invention consists in the novel and useful provi50 sion, formation, construction, association, and relative arrangement of parts, members and features, all as shown in a certain embodiment in the accompanying drawing, described generally, and more particularly pointed out in the claims. In the drawing: Figure 1 is an elevation of my improved therapeutic device, Figure 2 is a sectional view on the line 2-2 of Figure 1, Figure 3 is a cross sectional view on the line 3-3 of Figure 2, and, Figure 4 is a view similar to Figure 3, certain of the parts being in a changed relationship.

Referring now with particularity to the drawing, the improved therapeutic device as an entirety is designated by I, and the same includes an outer casing 2 which may be cylindrical in form and provided with one or more spaced segmental openings 3. The casing or housing is internally threaded inward from one end thereof, at 4. A fuel receptacle 5, constituting a tubular member 6 closed at one end 7, and provided with a threaded area at 8, is adapted to be received within a portion of the body 2 when the threads 8 engage the threads 4. The end 7 of the fuel receptacle acts as a cap for the end of the body, and in this particular, the diameter of the end or base 7 is greater than the external diameter of the body, as see the figures. This, of course, limits the reception of the fuel receptacle within the body 2. Telescopically received within the opposite end of the body is a tube 9. This tube is externally threaded at 10 to receive a threaded cap 11 at one end, and the opposite end of said tube is castellated, as shown at 12, that is to say, provided with spaced slots. These slots subtend substantially the same transverse area as the transverse area of the slots 3. However, the entire area of the slots 12 is not as great as the openings 3. Within the tube 9 is a container or receptacle 13. This receptacle, in the present instance, is in the form of an inverted hollow cone, the apex pointing downwardly, and it will be noted that this receptacle lies between ends of the tube 9. Internally spanning the housing 2 and substantially below the lowermost bounding edge of the openings 3 is a plate 14 formed with a central depression 15. This plate is adapted to have placed in the depression thereof some combustible substance, such as a combustible tablet 16.

The operation, uses, and advantages of the invention just described, are as follows: Normally, there is housed within the fuel receptacle 5 a plurality of tablets 16, which may be formed of methenamine or hexamethylenamine.

This substance is found to be readily ignitable, and to burn with intense heat. By separating the fuel receptacle from the body 2, in the usual manner, to-wit, unscrewing the two members, one of the tablets may be placed within the fuel receiving depression 15 of the plate or disk 14.

The cap 11 is removed from the tube 9, liquid placed within the receptacle 13, and the necessary drug dropped within said liquid. It will be seen that the tube 9 is of a length sufficient to permit the same to extend beyond the end of the housing 2. This construction allows the physician to relatively move the tubes. Hence, the height of the receptacle above the flame may be regulated, and by transversely turning the tube 9, air draft is likewise regulated. This air regulation is best illustrated in Figures 3 and 4, wherein it will be seen that the castellated construction of the tube 9 may permit a substantial closing of the openings 3 of the housing 2, or by rotating the member 9 within the housing, any degree of opening may be provided.

After the drug has been dissolved, the liquid may be drawn upwardly within a hypodermic syringe in the usual manner.

This invention is not, in any wise, limited to the character of drug used, as would be self-evident, and the receptacle 13 may contain a sterilizing solution for the purpose of sterilizing various small surgical instruments.

It is intended that a therapeutic device of the character disclosed should be of a size that readily permits it to be carried in the pocket or in the kit which surgeons usually are provided with for housing various physicians' accessories.

Whereas the devices now known to the inventor require separate entities for performing the function of dissolving a drug, the present inven3 5 tion by having all the units self-contained, presents a device which is always ready for use, with all the necessary members maintained in combination, with the result that it is not necessary to search through a kit in order to find each individual member. The importance of this becomes apparent when a physician is called upon in a case that requires immediate treatment. It is a simple matter to place one of the pellets 16 in the depression 15, to ignite the same after a small amount of liquid has been placed within the liquid receptacle 13 with the drug. While the drug is being dissolved the physician is adjusting the needle of his hypodermic syringe ready to immediately withdraw the liquid from the receptacle for injection. After the liquid has been withdrawn, the cap I may be replaced, and the member 6 likewise reinserted within the body, and the device may then be placed within the kit for further use as the occasion may arise.

The receptacle 13 is made frusto-conical or with sloping sides for the purpose of directing any liquid therein constantly toward the apex, with the result that when a hypodermic needle is inserted within the receptacle 13, all the liquid content may be withdrawn. It is further evident that the construction of the tube 9 is such that a tripod arrangement is provided, which may, under certain circumstances, be utilized without the member 2, and some combustible material may be placed upon any object and, when ignited will heat the member 13. The preferable arrangement is that described and illustrated.

It is obvious that various changes and modifications and variations may be made in practicing the invention in departure from the particular showing of the drawing and the description as given without, however, departing from the true spirit of the invention.
