Abstract
Abstract An apparatus and method for warming intravenous equipment is disclosed. The apparatus includes at least one warming device comprised of insulated wrap material having at least one removable and reusable heat pack supported along an inner insulated surface of the wrap material. The apparatus releasably encloses intravenous equipment such as I.V. bags and/or I.V. tubing. Two such warming devices can be attached together in series so that one warming device warms the I.V. bag while the other warms a substantial length of I.V. tubing. A flexible insulated strip of material is detachably connected to the wrap material and is used to insulate portions of the I.V. infusion equipment which must be easily accessible and which are neither required nor intended to be heated. The apparatus has particular use for warming intravenous equipment used in routine or emergency pre-hospital situations, especially in cold environments.

Claim 2
Dependent Claim
74 words
Apparatus in combination with intravenous equipment, said apparatus comprising: wrap material means for enclosing said intravenous equipment, said wrap material means having an interior surface and an exterior surface; at least one means for heating said intravenous equipment supported along said interior surface, said means for heating serving to heat said intravenous equipment when said wrap material means is enclosed thereabout; and means for releasably enclosing said wrap material means about said intravenous equipment.
Claim 3
Dependent Claim
20 words
The apparatus of claim 1 further comprising means for insulating positioned between said interior surface and said means for heating.
Claim 4
Dependent Claim
15 words
The apparatus of claim 2 further comprising means for replaceably retaining said means for heating.
Claim 5
Dependent Claim
17 words
The apparatus of claim 3 wherein said means for replaceably retaining comprise at least one elastic band.
Claim 6
Dependent Claim
17 words
The apparatus of claim 3 wherein said means for heating comprise at least one reusable heat pack.
Claim 7
Dependent Claim
61 words
The apparatus of claim 3 wherein said intravenous equipment comprises means for containing a supply of intravenous fluid, said wrap material having means for suspending said means for containing in a position of operable contact with said means for heating, said means for suspending further acting as means for suspending the weight of the apparatus, including any intravenous equipment enclosed therein.
Claim 8
Dependent Claim
95 words
The apparatus of claim 6 wherein said intravenous equipment further comprises means for conducting intravenous fluid from said means for containing, said wrap material means having means for supporting a substantial length of said means for conducting in a position of operable contact with said means for heating, whereby said means for supporting a substantial length of said means for conducting serves to support a maximum length of said means for conducting within said apparatus and adjacent said means for heating while minimizing the length of said means for conducting left exposed from said apparatus.
Claim 9
Dependent Claim
29 words
The apparatus of claim 7 wherein said means for supporting a substantial length of said means for conducting comprising means for permitting serpentine lacing of said means for conducting.
Claim 10
Dependent Claim
28 words
The apparatus of claim 8 further comprising means carried by said apparatus for detachably connecting said apparatus in a series arrangement with another apparatus for warming intravenous equipment.
Claim 11
Dependent Claim
31 words
The apparatus of claim 9 further comprising means detachably fastenable to said wrap material means for insulating portions of the intravenous equipment not intended for enclosure within said wrap material means.
Claim 12
Dependent Claim
76 words
The apparatus of claim 10 wherein said means detachably fastenable to said wrap material means for insulating portions of the intravenous equipment not intended for enclosure within said wrap material means comprise at least one detachable flexible strip having means for fastening along longitudinal side edges thereof, whereby said at least one strip is formable into a tubular enclosure for insulating said portions of the intravenous equipment not intended for enclosure within said wrap material means.
Claim 13
Independent Claim
107 words
A system for warming intravenous equipment including at least means for containing a supply of intravenous fluid and means for conducting intravenous fluid from said means for containing, said system comprising: a first device for warming said means for containing and a second device for warming a substantial length of said means for conducting, each of said first and second devices having at least one means for heating a respective one of said means for containing and said means for conducting associated therewith; and means carried by said first and second devices for detachably connecting said first and second devices to one another in a series arrangement.
Claim 14
Independent Claim
107 words
A system for warming intravenous equipment including at least means for containing a supply of intravenous fluid and means for conducting intravenous fluid from said means for containing, said system comprising: a first device for warming said means for containing and a second device for warming a substantial length of said means for conducting, each of said first and second devices having at least one means for heating a respective one of said means for containing and said means for conducting associated therewith; and means carried by said first and second devices for detachably connecting said first and second devices to one another in a series arrangement.
Claim 15
Dependent Claim
90 words
The system of claim 12 wherein each of said first and second devices comprise: wrap material means adapted for enclosure of one of said means for containing and said substantial length of said means for conducting, said wrap material means having an interior surface and an exterior surface, said at least one means for heating being supporting along said interior surface; and means for releasably enclosing said wrap material means about said intravenous equipment, whereby said means for heating heats said intravenous equipment when said wrap material is enclosed therearound.
Claim 16
Independent Claim
130 words
A method for warming intravenous equipment including at least means for containing a supply of intravenous fluid and means for conducing intravenous fluid from said means for containing, said method comprising: providing at least one wrap material means for enclosing said intravenous equipment, said wrap material means having at least one means for heating said intravenous equipment supported along an interior surface thereof; wrapping said at least one wrapping material means about one of said means for containing and a substantial length of said means for conducting for enclosure thereof and for permitting heat transfer thereto from said at least one means for heating; and providing means for releasably enclosing said wrap material means about one of said means for containing and said substantial length of said means for conducting.
Claim 17
Independent Claim
130 words
A method for warming intravenous equipment including at least means for containing a supply of intravenous fluid and means for conducing intravenous fluid from said means for containing, said method comprising: providing at least one wrap material means for enclosing said intravenous equipment, said wrap material means having at least one means for heating said intravenous equipment supported along an interior surface thereof; wrapping said at least one wrapping material means about one of said means for containing and a substantial length of said means for conducting for enclosure thereof and for permitting heat transfer thereto from said at least one means for heating; and providing means for releasably enclosing said wrap material means about one of said means for containing and said substantial length of said means for conducting.
