The scope punctures the initial membrane and enters the cavity between two bodies of absorbent material that contain fluid. The absorbent material is arranged such that the passage of a scope would be accommodated for different sizes of surgical scopes. A circuit board is located on the bottom of the chamber that has a design element used to warm the liquid to a temperature equal to or greater than the temperature of the proposed surgical environment. When the scope is located between the two absorbent bodies, the heat generated by the circuit board is transferred via the liquid and contacts the scope, warming it in preparation for surgery. ## Claims ### Claim 1 A cleaning and defogging device for use with a surgical scope during medical procedures, the device comprising: a housing defining a first cavity and a second cavity, the first cavity configured and arranged to receive a surgical scope in a generally vertical orientation, the second cavity configured and arranged to receive a surgical scope in a generally horizontal configuration, the housing having a first inlet communicating with the first cavity to allow a distal end of the surgical scope to be inserted into the first cavity through the first inlet, the housing having a second inlet communicating with the second cavity to allow a distal end of the surgical scope to be inserted into the second cavity through the second inlet; a cleaning fluid disposed in the first cavity; a heating element disposed in the housing such that heat is transferred from the heating element to the cleaning fluid; a V-shaped surface configured and arranged to receive a white balance referencing material, the V-shaped surface disposed inside the housing adjacent to the second cavity; and a power source configured and arranged to energize the heating element to produce heat for heating the cleaning fluid. ### Claim 2 (depends on 1) The device of claim 1, further comprising a cleaning material disposed in the first cavity. ### Claim 3 (depends on 2) The device of claim 2, wherein the cleaning material comprises a sponge. ### Claim 4 (depends on 2) The device of claim 2, wherein the cleaning material comprises a flexible material having a cross-hatched pattern. ### Claim 5 (depends on 2) The device of claim 2, wherein the cleaning material comprises a plurality of upstanding finger-like projections. ### Claim 6 (depends on 2) The device of claim 2, wherein the cleaning material comprises a material having a honeycomb-like structure. ### Claim 7 (depends on 1) The device of claim 1, wherein the first cavity and the second cavity are disposed in fluid communication. ### Claim 8 (depends on 7) The device of claim 7, wherein the cleaning fluid is disposed in the first and second cavity and is capable of moving therebetween. ### Claim 9 (depends on 1) The device of claim 1, further comprising an illumination source disposed adjacent to at least one of the first and second inlets. ### Claim 10 (depends on 1) The device of claim 1, further comprising a stand disposed in spaced apart relation to the second inlet, the stand configured and arranged to support the proximal end of the surgical scope when the distal end of the surgical scope is disposed in the second cavity. ### Claim 11 (depends on 1) The device of claim 1, further comprising a first subhousing having an upper surface and having a first subhousing cavity defined therein. ### Claim 12 (depends on 11) The device of claim 11, wherein the upper surface of the subhousing is configured and arranged to support a circuit board having a heating element disposed thereon. ### Claim 13 (depends on 12) The device of claim 12, further comprising a power source disposed inside the subhousing cavity. ### Claim 14 (depends on 13) The device of claim 13, wherein the power source comprises a plurality of batteries. ### Claim 15 (depends on 12) The device of claim 12, further comprising a second subhousing having a chamber forming the first cavity and having a V-shaped exterior surface for receiving the white balance reference material. ### Claim 16 (depends on 1) The device of claim 1, further comprising a second cleaning material disposed in the second cavity, the second cleaning material having a first portion and a second portion disposed in spaced apart relation such that a gap is formed between the first and second portions, the surgical scope being received in the gap and making contact with the first and second portions when the surgical scope is inserted into the second cavity through the second inlet. ### Claim 17 (depends on 1) The device of claim 1, wherein the heating element is a resistance type electrical heating element incorporated into an electrical circuit. ### Claim 18 (depends on 17) The device of claim 17, wherein the electrical circuit comprises a printed circuit board. ### Claim 19 (depends on 17) The device of claim 17, wherein the circuit comprises a thermistor for controlling the temperature of the cleaning solution within the housing. ### Claim 20 (depends on 17) The device of claim 17, wherein the circuit electronically adjusts for varying voltage over the life of a battery by pulse width modification. ### Claim 21 (depends on 19) The device of claim 19, wherein the thermistor and the heating element are incorporated into a single printed circuit board. ### Claim 22 A cleaning and defogging device for use with a surgical scope during medical procedures, the device comprising: a housing defining a first cavity and a second cavity, the first cavity configured and arranged to receive a surgical scope in a generally vertical orientation, the second cavity configured and arranged to receive a surgical scope in a generally horizontal configuration, the first cavity and second cavity disposed in fluid communication, the housing having a first inlet communicating with the first cavity to allow a distal end of the surgical scope to be inserted into the first cavity through the first inlet, the housing having a second inlet communicating with the second cavity to allow a distal end of the surgical scope to be inserted into the second cavity through the second inlet;
