Abstract

Abstract Auxiliary suction equipment for performing a medical operation. A flexible mat partitions off an organ to be operated on from other internal organs, and a suction tube removes blood and body fluid caused by the operation. The insulating qualities of the mat allow the procedure to be performed with the protection of the organ muscle by a local low-temperature method in order to control the metabolism of the organ to be operated on. The mat can be provided with a passage to introduce a fluid for controlling the temperature of the mat surface.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 154 words
Suction equipment for use in a medical operation, comprising: a partition plate, said partition plate being formed of a soft, elastically bendable material and having sufficient area to substantially encompass an internal organ and sufficient thickness to allow bending to substantially encompass the organ; a plurality of projections spaced upon and extending from an upper surface of said partition plate; passage means including an enclosed cavity extending through the interior of said partition plate; suction means, including a flexible tube, one end of said flexible tube being mounted on said upper surface of said partition plate, said one end of said flexible tube having at least one opening for the introduction of fluids into said tube, the other end of said flexible tube being adapted for connection to a suction pump; and means for circulating a fluid medium through said passage means to control the temperature of said upper surface of said partition plate.
Claim 2
Dependent Claim 154 words
Suction equipment for use in a medical operation, comprising: a partition plate, said partition plate being formed of a soft, elastically bendable material and having sufficient area to substantially encompass an internal organ and sufficient thickness to allow bending to substantially encompass the organ; a plurality of projections spaced upon and extending from an upper surface of said partition plate; passage means including an enclosed cavity extending through the interior of said partition plate; suction means, including a flexible tube, one end of said flexible tube being mounted on said upper surface of said partition plate, said one end of said flexible tube having at least one opening for the introduction of fluids into said tube, the other end of said flexible tube being adapted for connection to a suction pump; and means for circulating a fluid medium through said passage means to control the temperature of said upper surface of said partition plate.
Claim 3
Dependent Claim 31 words
Suction equipment as in claim 1, wherein said means for circulating includes an exit port and an inlet port adapted to be connected with a circulating pump for circulating the medium.
Claim 4
Dependent Claim 254 words
Suction equipment for use in a medical operation, comprising: a partition plate, said partition plate being concavely curved in mutually perpendicular directions and having a front face on the concave surface thereof, said partition plate formed of an abiabatic, soft, elastically bendable material and having sufficient area to substantially encompass an internal organ to be operated on and thickness which is sufficiently small to allow easy bending to substantially encompass the organ to be operated on, whereby the encompassed organ can be subjected to a local low temperature on the front face while the surrounding area on the opposite side from said front face is thermally insulated from the low temperature by said partition plate; a plurality of projections on said front face spaced from each other and extending outwardly from said front face of said partition plate; suction means, including a flexible tube, one end of said flexible tube being mounted on said front face of said partition plate between said projections and with said projections closest to said tube being spaced laterally therefrom, said one end of said flexible tube having a laterally of openings therein at least along the opposite lateral sides thereof adjacent said projections for the introduction of fluids into said tube, the other end of said flexible tube being adapted for connection to a suction pump; and auxiliary tube means extending along and attached to said flexible tube and having one end adjacent said openings for introducing air to a location proximate said openings of said flexible tube.
Claim 5
Dependent Claim 254 words
Suction equipment for use in a medical operation, comprising: a partition plate, said partition plate being concavely curved in mutually perpendicular directions and having a front face on the concave surface thereof, said partition plate formed of an abiabatic, soft, elastically bendable material and having sufficient area to substantially encompass an internal organ to be operated on and thickness which is sufficiently small to allow easy bending to substantially encompass the organ to be operated on, whereby the encompassed organ can be subjected to a local low temperature on the front face while the surrounding area on the opposite side from said front face is thermally insulated from the low temperature by said partition plate; a plurality of projections on said front face spaced from each other and extending outwardly from said front face of said partition plate; suction means, including a flexible tube, one end of said flexible tube being mounted on said front face of said partition plate between said projections and with said projections closest to said tube being spaced laterally therefrom, said one end of said flexible tube having a laterally of openings therein at least along the opposite lateral sides thereof adjacent said projections for the introduction of fluids into said tube, the other end of said flexible tube being adapted for connection to a suction pump; and auxiliary tube means extending along and attached to said flexible tube and having one end adjacent said openings for introducing air to a location proximate said openings of said flexible tube.
Claim 6
Dependent Claim 33 words
Suction equipment as in claim 3, wherein said area of said partition plate is of a substantially round shape, and said one end of said tube is mounted substantially at the center thereof.
Claim 7
Dependent Claim 15 words
Suction equipment as in claim 3, wherein each of said projections has a cylindrical dot-shape.
Claim 8
Dependent Claim 19 words
Suction equipment as in claim 3, wherein each of said projections extends along said partition plate in a line.
Claim 9
Dependent Claim 37 words
Suction equipment as in claim 3, wherein said partition plate is provided with a line of perforations extending therethrough, whereby a portion of the partition plate may be removed to reduce said area of said partition plate.
Claim 10
Dependent Claim 15 words
Suction equipment as in claim 3, wherein said partition plate is an integrally molded unit.
Claim 11
Dependent Claim 55 words
Suction equipment as claimed in claim 3, wherein said partition plate further includes an extra portion of said sufficient thickness and formed of said material integrally extending from a portion of the periphery of said partition plate a distance greater than the cross-sectional site of said projections, said extra portion being devoid of said projections.
