Abstract
Abstract The combined splint and container comprises an inflatable splint having inner and outer walls defining an inflatable chamber and a flexible container wall disposed in face to face spaced relation to the inner wall and connected thereto at its margins and extending from one end thereof to and beyond the other end, so as to form with the inner wall a container for coolant. The splint and container are placed in embracing relation to a member to be treated with the container, filled with coolant, usually crushed ice, in in contact with the member. While held in embracing relation, the splint is inflated by oral pressure so as to stiffen the splint and force the container wall into embracing relation, under preselected pressure contact, to the member about the entire periphery of the embraced portion of the member. The splint and container may be of permanent sleeve shape or a sleeve having separable lateral margins which are detachably held together when the splint is installed and are separable so that the sleeve can be opened along one side for convenience in installing it on the member.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
216 words
A combined pressure splint and coolant container comprising: an elongated inflatable splint having inner and outer walls, respectively, of impervious, flexible, substantially inelastic material sealed together at their margins so as to define therebetween an air receiving and holding chamber, and which are sealed together at elongated narrow areas which extend lengthwise of the walls and are spaced apart from each other transversely of the walls, and which areas terminate endwise in spaced relation to the ends of said walls, to divide the air receiving chamber into a plurality of compartments in communication with each other at their ends, and inlet means for permitting introduction of air into the chamber for inflating the splint and for preventing the escape of air through said means; a container wall of flexible sheet material in face to face spaced relation to said inner wall and connected thereto along part only of its periphery so as to define between the inner wall and container wall a container for holding treating material, which container has an opening to permit filling and emptying; and said splint and container wall being constructed and arranged so that the splint and container wall can be placed in embracing relation with an injured member of a user with the container wall juxtaposed against the embraced member.
Claim 2
Dependent Claim
216 words
A combined pressure splint and coolant container comprising: an elongated inflatable splint having inner and outer walls, respectively, of impervious, flexible, substantially inelastic material sealed together at their margins so as to define therebetween an air receiving and holding chamber, and which are sealed together at elongated narrow areas which extend lengthwise of the walls and are spaced apart from each other transversely of the walls, and which areas terminate endwise in spaced relation to the ends of said walls, to divide the air receiving chamber into a plurality of compartments in communication with each other at their ends, and inlet means for permitting introduction of air into the chamber for inflating the splint and for preventing the escape of air through said means; a container wall of flexible sheet material in face to face spaced relation to said inner wall and connected thereto along part only of its periphery so as to define between the inner wall and container wall a container for holding treating material, which container has an opening to permit filling and emptying; and said splint and container wall being constructed and arranged so that the splint and container wall can be placed in embracing relation with an injured member of a user with the container wall juxtaposed against the embraced member.
Claim 3
Dependent Claim
51 words
The structure according to claim 1 wherein said container wall has elongated areas extending endwise of the splint, bonded to the inner wall of the splint partway only of the length of the splint at a plurality of locations spaced apart from each other transversely of the length of the splint.
Claim 4
Dependent Claim
22 words
The structure according to claim 2 wherein each of said bonded areas terminates in spaced relation to both ends of the splint.
Claim 5
Dependent Claim
40 words
The structure according to claim 1 wherein said container wall is impervious and imperforate and is bonded in sealed relation to the inner wall of the splint along the entire lateral margins and one end margin of the container wall.
Claim 6
Dependent Claim
62 words
The structure according to claim 1 wherein the container wall extends endwise of the splint outwardly beyond the end of the splint opposite from said one end margin of the container wall sufficiently so that the portion so extending can be folded over the splint at said one end and overlie the outer peripheral margin of the splint at said one end.
Claim 7
Dependent Claim
70 words
The structure according to claim 1 wherein the container wall is attached at its lateral margins and at said one end margin, to the splint over a total area of such a limited extend transversely and lengthwise of the splint that the space between the container wall and splint is open at said opposite end for substantially the entire extent of the splint transversely of the length of the splint.
Claim 8
Dependent Claim
77 words
The structure according to claim 1 wherein the splint has two sealed lateral margins extending lengthwise of the splint and separable from each other: releasable connecting means are connected to the splint and are manually operable to hold said margins in fixed position relative to each other and to release said margins, selectively; and the container wall has lateral margins separated from each other and bonded in fixed position to said lateral margins of the splint, respectively.
