Aug. 16, 1955 G. A. GIARDINI LOCALIZED APPLICATOR FOR COOLING BODY TEMPERATURES Filed June 11, 1954 2 Sheets-Sheet 1 Aug. 16, 1955 G. A. GIARDINI 2,715,315


Application June 11, 1954, Serial No. 436,162

4 Claims. (Cl. 62-1) This device relates to a device for applying a coolant to localized portions of the human body. More particularly, the invention comprises a container within which may be positioned a suitable coolant, such as solid carbon dioxide, more commonly known as Dry Ice, or some similar cooling device. Specifically, the applicator is adapted for applying the coolant to localized portions of the body for either lowering the body temperature and preventing the ill effects which might otherwise accompany the same, or for therapeutic purposes in the case of sweliings and the like.

The application of coolants such as ice or cold Water to the human body for the prevention of heat prostration or for therapeutic purposes in the case of excessive body fever or swellings or other such body injuries, is well known. Heretofore such applications necessitated the use of ice packs or the like. However, ice packs are usually cumbersome, damp and messy, and for many other reasons, are not always suitable.

It is also well known that certain portions of the body, particularly those portions in which the blood vessels are positioned close to the surface, respond readily to coolants and effectively cool the body temperatures when so applied. For example, the application of coolants to the wrists or to the temples, is often prescribed in the case of heat prostration. The reason, of course, is the fact that at these points in the body, major blood vessels lie close to the surface.

It is therefore an important object of my invention to provide a practical coolant applicator which may eifectively apply a highly desirable coolant to these parts of the body as well as other parts for the purpose of lowering the body temperature.

According to my invention, I provide a light-weight plastic receptacle in which may be positioned a coolant such as Dry Ice, which sublimes passing directly from the solid phase to the gaseous phase at such low temperatures that no liquid by-products result therefrom. The invention is further provided with suitable insulating means to prevent excessively rapid cooling of the portions of the body or skin to which the applicator is applied. My device is further designed so that it may be used effectively wherever necessary, including such body members as the wrist, eyes, forehead, nape of neck, or any other body areas where a coolant ordinarily may be effectively utilized.

1 further provide a Dry-Ice pellet so designed and packaged that it may be handled and transported with minimum inconvenience and maximum utility.

A further object of the invention is to provide elfective means within the container itself to maintain the coolant in the most effective position with respect to the skin or body portions.

Still another object is to afford an applicator device of non-metallic construction so as to minimize the danger from excessive cooling which would otherwise result in burns.

2,7 15,315 Patented Aug. 16, 1955 ice Yet a further object is to provide a coolant applicator which may be worn on the body without excessively interfering with the actions or movements of the wearer.

Still a further object is to afford a coolant applicator of simple, inexpensive construction, yet attractive and most effective in performing the functions intended.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel features of construction, arrangement and a combination of parts hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportion, size and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

For the purpose of facilitating an understanding of my invention, I have illustrated in the accompanying drawings a preferred embodiment thereof, from an inspection of which, when considered in connection with the follow ing description, my invention, its mode of construction, assembly and operation, and many of its advantages should be readily understood and appreciated.

Referring to the drawings in which the same characters of reference are employed to indicate corresponding or similar parts throughout the several figures of the drawmgs:

Fig. l is a perspective view of the hand, wrist and arm portion of a human being with my applicator operationally positioned thereon;

Fig 2 is an exploded view of the applicator showing the various members thereof including the pellet of Dry Ice;

Fig. 3 is an enlarged sectional view taken on the plane of line 33 of Fig. 5 of the drawings and viewed in the direction indicated;

Fig. 4 is a top plan view of the applicator with portions broken away to better illustrate the inside construction;

Fig. 5 is a transverse sectional view taken on the plane of line 5-5 in Fig. 3 of the drawings and viewed in the direction indicated; and

Fig. 6 is a perspective view of the assembled applicator with the Dry Ice pellet contained therein.

Turning now to the several figures of the drawings, reference numeral 10 indicates generally the applicator which comprises an outer plastic shell 12, preferably of a fairly stiff construction. This shell may be of any suitable shape but in the embodiment chosen for illustration, is semi-circular with an arcuate wall 14 and fiat side wall members 16 and 18. Both ends of the arcuate wall project upwardly at the top to afford segments 20 and 22 within which may be formed slots such as 24 and 26. The flat sides 12 and 14 project upwardly above the mouth of the case 12 thereby providing flaps such as 28 and 39. These flaps are adapted to fold over, thereby covering the open mouth of the case.

The slots are adapted to accommodate therein the ends 32 and 34 of straps 36 and 38. The ends 32 and 34 may be enlarged or folded over to prevent their being unintentionally or accidentally removed from the slots. The opposite ends of the straps 36 and 38 may be perforated or formed with suitable fastening devices such as shown as 40 in Figs. 3 and 6 of the drawings. These straps may be made of any suitable material and of any desired lengths so that they may be conveniently positioned to hold the device in position on any desired portion of the body.

To properly insulate the coolant from the body, a liner such as 42 is positioned within the outer casing 12 and may be permanently afiixed as by a layer of cement 44 within the casing 12. This liner may be made of rubber or rubberized cloth and is of essentially the same shape but slightly smaller size thanthe outer casing 12. It may be provided with a plurality of flaps such as 46, 48, 50 and 52, which are designed to fold over the closed mouth of the liner. The liner is further provided with a-rubber band 54 which is fastened at its ends to the arcuate'wall portion .56 of the liner 42, so that it is suspended between the upper sides of the arcuate wall 56 depending thereinbut spaced from the bottom of the liner, essentially as shown in Fig. 3 of the drawings. Thepurpose of this rubber band will become apparent as..the. description proceeds. 7

.Within the liner 42 maybe positioned the coolant pellet 58which is shaped so that it may be readily inserted the liner. This pellet may be wrapped in a suitable wrapper such as the paper wrapper 60 illustrated in Fig. 2 of the drawings. This wrapping not only retards the'sublimation of the carbon dioxide, but, moreover, serves as an insulator, thereby enabling the convenient handling of the pellet.

In operation, after the pellet is positioned within the container so that it abuts the rubber band 54 within the liner 42; the flaps 46, 48, 59 and 52 are then folded over the top of the pellet and the outer casing flaps 28 and 30 are likewise folded thereover. This, of course, isaccomplished against the contracting tendency of the elastic rubber band 54 to return from its stretched position to its unstretched position. Thus the stretched rubber band tends to keep the pellet in its most effective position, namely against the flaps and thereby against the body portion of the wearer. Hence, despite the reduction in size of the pellet as it sublimes, it nevertheless at all times, is kept in its most effective and proximate position to the body of the wearer by the elastic band 54.

After the pellet has been properly positioned and insulated within the various folds or flaps of the device,.it ispositioned properly and the bands 36 and 38 are positioned to encircle thearm or head or other member of the body so that it is able to perform the cooling functions intended.

It' should further be noted that although the device has been especially designed for use in connection with a coolant such as solid carbon dioxide, other coolants may be'utilized therein, including ice and even refrigerated metal pellets. It has been found that pre-cooled aluminum pellets are most effective and when properly positioned and insulated within the applicator, serve admirably in lowering the body temperature.

' It will be apparent from the foregoing description that I have provided a most economical but effective device for applying coolants to strategic portions of the human body to cool the blood and thereby lower the body temperatures when necessary. This may be effectively utilized for preventing heat prostration and for treating prostration once it has occurred. It may also be efiectively utilized in cases' where excessive body 'fever is present. Likewise, it may be used therapeutically in the case of swellings and other body injuries. The device is so constructed that it minimizes, if not entirely eliminates, the danger of injury to the wearer by burns caused by excessive cooling when sharp coolants such as Dry Ice are employed. It is light in weight and provided with means for effectively mounting the applicator on any desired portion of the body and maintaining the same in position without interfering with normal body movements.

It is believed that my invention, its mode of constructions and assembly, and many of its advantages should be readily understood from the foregoing without further description, and it should also be manifest that while a preferred embodiment of the invention has been shown.
