Device for cleansing measuring pressure in the colon

Claim 1

A device for cleansing the colon, comprising: a cylinder-shaped housing made of an elastic material; working end of said housing; a discharge channel in said housing; ports of said discharge channel in said housing end adapted for delivering a lavation solution into the colon; an aspiration channel in said housing, isolated from said discharge channel; ports of said aspiration channel in said housing end adapted for receiving the contents of said colon washed out by said lavation solution; a reservoir for said lavation solution; a first piping communicating said reservoir for the lavation solution with said discharge channel; a receptacle for accepting the contents of said color washed out by said lavation solution; a second piping which establishes communication between said receptacle and said aspiration channel; an endoscope accommodated in said aspiration channel and having a working portion brought outwards from said channel through an opening in said housing working end; an expandable transparent balloon provided on said working portion of said endoscope extending through and out of said aspiration channel through an opening in said working end of said housing; means for expanding said balloon after it has been introduced into the colon to achieve effective pressurization and sealing in the area of contact between the walls of the balloon and the colon walls; a tube means extending in said discharge channel for transmitting the pressure in the colon, one end of said tube means extending out of said working end of said housing and the other end of said tube means extending out of a proximal end of said housing for connection to a pressure measuring means; and means for adjusting the pressure head and the suction head in said respective first and second pipings.

Claim 2

A device for cleansing the colon, comprising: a cylinder-shaped housing made of an elastic material; working end of said housing; a discharge channel in said housing; ports of said discharge channel in said housing end adapted for delivering a lavation solution into the colon; an aspiration channel in said housing, isolated from said discharge channel; ports of said aspiration channel in said housing end adapted for receiving the contents of said colon washed out by said lavation solution; a reservoir for said lavation solution; a first piping communicating said reservoir for the lavation solution with said discharge channel; a receptacle for accepting the contents of said color washed out by said lavation solution; a second piping which establishes communication between said receptacle and said aspiration channel; an endoscope accommodated in said aspiration channel and having a working portion brought outwards from said channel through an opening in said housing working end; an expandable transparent balloon provided on said working portion of said endoscope extending through and out of said aspiration channel through an opening in said working end of said housing; means for expanding said balloon after it has been introduced into the colon to achieve effective pressurization and sealing in the area of contact between the walls of the balloon and the colon walls; a tube means extending in said discharge channel for transmitting the pressure in the colon, one end of said tube means extending out of said working end of said housing and the other end of said tube means extending out of a proximal end of said housing for connection to a pressure measuring means; and means for adjusting the pressure head and the suction head in said respective first and second pipings.
