SNAKE BITE KIT Filed Nov. 50, 1944 2 Sheets-Sheet 2 INVENTOR. ROBERT K CUTTER 7Jm ATTORNEY Patented Aug. 24, 1948 SNAKE BITE mr Robert K. Cutter, Berkeley, Calif., assgnor to Cutter Laboratories, Berkeley, Calif., a corporation of California Application November 30, 1944, Serial No. 565,937 Claims. (Cl. 20G-63.2)

This application is a continuation in part of my prior application Serial Number 297,478, filed on October 2, 1939, for improvements in a snake bite kit.

This invention relates to a snake bite kit suitable for ready use in the field.

To be of any real use, a snake bite outfit must be immediately avail-able at the time that the bite is inflicted and consequently -it must be of such size that it can be conveniently carried in the users pocket. It should contain a tourniquet, a lancet, an antiseptic applicator, and a suction device. Although there are now available on the market snake bite outfits containing all of these essential articles, they are of such size as to be considered excess baggage by individuals who are out hunting or fishing and desire to travel as light as possible. The smallest size kit now on the market of which applicant has knowledge is 2" Wide by 41/8" long, and although this may appear to be relatively small, it is considered by many Sportsmen, because of its size, as excess baggage. Furthermore, the kits now available are invariably packed in relatively hard containers which are uncomfortable to carry about in the pockets of Wearing apparel.

In general, the object of this invention is the provision of a compact, efficient, and relatively water-tight snake bite outfit which can be readily and comfortably carried in any pocket of the user and be forgotten until occasion requires its use.

Another object of the invention is the provision of a snake bite outfit in which the receptacle for the tourniquet, lancet, and applicator serves as a suction device.

Still another object of the invention is the provision of a suction device having a concave mouth for conforming about a portion of the surface of a finger or other curved part of the body so as to form an effective vacuum seal.

A still further object of the invention is the provision of a knife or lancet formed with a spool for the reception of a tourniquet, and with an antiseptic container.

A further object of the invention is the provision of a snake bite outfit receptacle formed of a rel-atively soft material having appreciable frictional resistance with fabrics, so as to avoid any chance of its slipping from the pocket of a user.

The invention possesses other advantageous features, some of which with the foregoing will be set forth at length in the following description where those forms `of the invention whichhave been selected for illustration in the drawings accompanying and forming a part of the present speciiication are outlined in full. In said drawings, several forms of the invention are shown, but it is to be understood that it is not limited to such forms, since the invention as set forth in the claims may be embodied in a plurality of other forms.

Referring to the drawings:

Figure 1D is a longitudinal section of the kit shown in Figure 9.

In carrying out the objects of my invention and as shown in Figures 1, 2, and 3, I resort to the use of a pair of telescoping tubular receptacles ll and l2. Preferably each -of these receptacles is made of rubber of such character as to be compressible and resilient so that each can be used as a suction device for withdrawing venom from a snake bite inflicted on any part of the body. 'I'he receptacle Il is formed with a hemispherical .closed end orl dome I3 and witht a straight open mouth I4. The outer diameter of the receptacle l2 should be substantially equal to the inner diameter of the receptacle Il. Formed on the closed end of the receptacle l2 is a hemispherical dome I3a of a diameter equal to the diameter of the receptacle Il and which provides a shoulder l5 against which the mouth I4 of the receptacle Il may be sealed. vThe mouth I6 of the receptacle I-2 is made concave so as to .conform more readily to the surface of any portion of the body having a considerable curvature, such as for example a finger. Molded on the outer surface of each of the receptacles Il and l2 are a plurality of longitudinally spaced circumferential ribs I7 and a plurality of circumferentially spaced longitudinal ribs I8. These ribs reinforce the relatively thin compressible walls of the receptacles so that after being laterally compressed when applying them to a bite, they will quickly reassume their normal cylindrical form, thereby to create a partial vacuum over the bite. Furthermore, due to the fact that the ribs on the smaller receptacle I2 only permit a fraction of its surface to come into contact with the inner walls of the larger receptacle the frictional resistance between the two receptacles when being opened or closed is materially reduced. This frictional resistance, which of course also depends upon the relation between the external diameter of the smaller receptacle and the internal diameter of the larger receptacle, should be sufficient normally toV hold the receptacles closed and still not so great as to cause inconvenience in opening them. The ribs on the outer surface of the larger receptacle form an irregular surface which `increases the frictional resistance between the receptacle and fabrics with which it may come in contact. This feature is of considerable importance, for due to it the chances of a snake bite outfit accidentally slipping out of a users pocket and thereby being lost are greatly diminished.

Disposed within the smaller receptacle il! and closedby the larger receptacle is a lancet 2|, a tourniquet 22, and an antiseptic applicator 23, all tightly Wrapped in a direction sheet 24.

The lancet 2| is formed of a strip of metal provided with a pointed blade and with a lateral extension or spool 26 about Which the tourniquet 22 may be wound. The tourniquet 22 preferably consists of a section of e tape` of sufficient length to be Wrappedaround the arm or leg so as to cut off further circulation through the lymph vessels lying just below theskin.

The applicator simply contains iodineor other antiseptic for disinfecting the lancet and the bite.

The assembled device as shown in Figure 2 is three inches long and one inch in diameter and can therefore be carried by a sportsman inany pocket ready for use with no more .inconvenience than carrying a pocket knife. The receptacles Il and l2 forming the container for the rest of the equipment may each be used as a suction cup, and this feature is highly desirable, for inspite of the use of a constrictor or tourniquet, the venom gradually progresses in .all directions through the lymph vessels, thereby making the use of a number of incisions and suction cups advantageous. It will therefore be seen that my device has the double advantage of providing a pair of eiicient suction cups and of providing a very compact kit by utilizing the suction cups as a container for the other necessary equipment. Due to the resiliency of the container so formed, its freedom from sharp edges and corners, and its adherence to fabrics, it may be conveniently and comfortably carried in a pocket Without any appreciable danger of losing it. Furthermore the device is relatively water-proof and therefore short intervals of immersion will in no way impair its contents.

In Figure 7 a modified receptacle is shown comprisinga pair of abutting rubber vacuum cups 3| :and 32. Disposed within these cups and secured to the cup 3| either by frictional engagement or by cement is a transparent plastic sleeve 33 preferably made of Lucite or other similar material. Surrounding the outer surfaces of the vacuum cups 3| and 32 and secured to the cup 32 is a similar transparent sleeve 34. When the cups 3| and 32 are pulled apart, the sleeve 33 adheres to the cup 3| and the sleeve 313 to the cup 32. Each transparent sleeve therefore serves as a window for its associated vacuum cup, through which the user may ascertain the quantity of venom being Withdrawn by the device.

Obviously a tubular window of this character may be spliced or added to the open ends of the suction cups shown in Figures 1, 2, 3, and 4.

The modification shown in Figures 8, 9, and 10, comprises a pair of identical, closed ended tubular members |||Y and 42 similar to but relatively sh'orterthan the receptacle Il shown in Figures 1,2 and- 3. vArranged for telescopic engagement within the members 4| and 42 is receptacle 43 similar to the receptacle I2 shown in Figures 1,- 2 and- Sibut which is not provided with a dome extending outwardly beyond its lateral walls as is the receptacle I2. Telescopically disposed within the receptacle 43 is a rolled direction sheet 24 containing the required accessory equipment as shown in Figures 5 and 6. From this description and from a study of Figures l, 2, 3, 8, 9 and 10, it will be observed that in this latter modification the inner receptacle |33 is telescoped and entirely housed with the outer end receptacles ll'l and 42 and that all three receptacles can be used as Vacuum cups. Furthermore the overall size of this modification need be no larger than the modification shown in Figures 1, 2 and 3.

In conclusion, it should be noted that in the removal of venom from a patient bitten by a snake, incisions are progressively made away from the wound and as many vacuum cups applied to them as are available. It is for this reason among others that the modification last described is particularly advantageous for, as above stated, it provides three vacuum cups without any increase in size.

I claim:

, 1. A pair of telescopically disposed compressible resilient tubular members having opposed closed ends, said members together forming a container for accommodating the accessory equipment of a snake bite outt and each forming a suction device for the removal of venom from a snake bite or incision.

2. A compressible and resilient tubular receptacle closed at one end and provided at its opposite end with a transparent ring, said receptacle serving as a container for accessory equipment of a snake bite outfit and as a suction device for the removal of venom from a snake bite.

3.
