Abstract
Abstract A snake-bite kit providing greater variation in the degree of suction available for removing venom from a snake bite. A pair of telescopically disposed compressible resilient tubular members with opposite closed ends contains the remainder of the kit. Both of these members have a flattened oval-cross section, and they are relatively small, so that the assembly is easily carried in the pocket. Their flat long front and rear walls are joined by short arcuate side walls; the distance along the major axis enables the spanning of fang marks of a larger snake. Pressure applied along the short axis produces a gentler suction than does pressure applied along the long axis. Pressure may be applied along the short axis by a person with weaker fingers than can apply operative pressure to a bulb having a circular annular cross section.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
59 words
An elastomeric tubular member for removing harmful fluids from a living body, said member being open at one end and closed at the other and having means providing different compression points between its ends at different rotational positions relative to a transverse section, which provide different degrees of suction at said open end when said member is manually squeezed.
Claim 2
Dependent Claim
59 words
An elastomeric tubular member for removing harmful fluids from a living body, said member being open at one end and closed at the other and having means providing different compression points between its ends at different rotational positions relative to a transverse section, which provide different degrees of suction at said open end when said member is manually squeezed.
Claim 3
Dependent Claim
51 words
A compressible resilient bulb for removal of venom from a snake bite said bulb having an open end and one transverse axis significantly greater than another transverse axis to provide a different degree of suction when said bulb is squeezed along said one axis than when squeezed along said other axis.
Claim 4
Dependent Claim
51 words
A compressible resilient bulb for removal of venom from a snake bite said bulb having an open end and one transverse axis significantly greater than another transverse axis to provide a different degree of suction when said bulb is squeezed along said one axis than when squeezed along said other axis.
Claim 5
Dependent Claim
43 words
A compressible, resilient bulb for removal of venom from a snake bite said bulb having, in transverse cross-section in at least one area, one axis greater than another and having an open end applicable to the skin area around a said snake bite.
Claim 6
Dependent Claim
43 words
A compressible, resilient bulb for removal of venom from a snake bite said bulb having, in transverse cross-section in at least one area, one axis greater than another and having an open end applicable to the skin area around a said snake bite.
Claim 7
Dependent Claim
58 words
An elastomeric tube for use in extracting poison from a living body, said tube being open at one end and closed at the other and having in transverse cross-section a wall thickness that is greater across one transverse axis than across an axis perpendicular thereto to cause different axes of transverse compression to vary the degree of suction.
Claim 8
Dependent Claim
58 words
An elastomeric tube for use in extracting poison from a living body, said tube being open at one end and closed at the other and having in transverse cross-section a wall thickness that is greater across one transverse axis than across an axis perpendicular thereto to cause different axes of transverse compression to vary the degree of suction.
Claim 9
Dependent Claim
54 words
A variable-suction generating device for venom removal consisting of an elastomeric tubular member open at one end and closed at the other, said open end having a long axis and a short axis at points normal to the longitudinal axis of said tubular member, said long axis being significantly longer than said short axis.
Claim 10
Dependent Claim
54 words
A variable-suction generating device for venom removal consisting of an elastomeric tubular member open at one end and closed at the other, said open end having a long axis and a short axis at points normal to the longitudinal axis of said tubular member, said long axis being significantly longer than said short axis.
Claim 11
Dependent Claim
93 words
A compressible and resilient tubular receptacle closed at one end and able to serve as a suction device for the removal of venom from a snake bite, characterized by an oval shape in which the suction member has front and rear walls that are relatively flat and side walls that are relatively round, whereby an increase in suction pressure is obtained by pressing the side walls together as distinguished from pressing the front and rear walls together and also a greater distance is covered with the device in one axis than in another.
Claim 12
Dependent Claim
93 words
A compressible and resilient tubular receptacle closed at one end and able to serve as a suction device for the removal of venom from a snake bite, characterized by an oval shape in which the suction member has front and rear walls that are relatively flat and side walls that are relatively round, whereby an increase in suction pressure is obtained by pressing the side walls together as distinguished from pressing the front and rear walls together and also a greater distance is covered with the device in one axis than in another.
Claim 13
Dependent Claim
118 words
In a snake-bite kit, a pair of telescopically disposed compressible resilient tubular members having opposed closed ends and forming a container for accommodating the accessory equipment for the snake-bite kit, each said tubular member forming a suction device for the removal of venom from a snake bite or incision, characterized by both of said resilient tubular members having a flattened cross section with two opposite long flat front and rear walls joined by two short arcuate side walls, whereby, pressure exerted on the two flat walls produces relatively gentle suction and pressure exerted on the arcuate walls produces stronger suction, and whereby in its long dimension each tubular member covers a greater distance, as that between two fangs.
Claim 14
Dependent Claim
118 words
In a snake-bite kit, a pair of telescopically disposed compressible resilient tubular members having opposed closed ends and forming a container for accommodating the accessory equipment for the snake-bite kit, each said tubular member forming a suction device for the removal of venom from a snake bite or incision, characterized by both of said resilient tubular members having a flattened cross section with two opposite long flat front and rear walls joined by two short arcuate side walls, whereby, pressure exerted on the two flat walls produces relatively gentle suction and pressure exerted on the arcuate walls produces stronger suction, and whereby in its long dimension each tubular member covers a greater distance, as that between two fangs.
Claim 15
Dependent Claim
33 words
The snake-bite kit of claim 7, wherein the smaller tubular member has a convex open mouth along the front and rear walls, said walls being beveled toward the inner surface adjacent the mouth.
Claim 16
Dependent Claim
23 words
The snake-bite kit of claim 7 wherein the open end is at least twice as wide in one direction as in the other.
