A gas supply apparatus is provided and has first and second fittings and first and second tubes. The first fitting is provided to discharge a gas of a first pressure therethrough, while the second fitting is provided to discharge a gas of a second pressure therethrough. The first tube has one end to which a first connector connectable to the first fitting is attached and supplies the first-pressure gas to a first body cavity of a subject. The second tube has one end to which a second connector connectable to the second fitting is attached and supplies the second-pressure gas to a second body cavity of the subject. The apparatus may comprise an erroneous-connection preventing device preventing an erroneous connection including at least one of a connection of the first connector to the second fitting and a further connection of the second connector to the first fitting.

What is claimed is: 1. A gas supply apparatus comprising: a first fitting through which a gas of a first pressure is discharged; a second fitting through which a gas of a second pressure is discharged; a first tube having one end to which a first connector connectable to the first fitting is attached and supplying the gas of the first pressure to a first body cavity of a subject to be medically treated; a second tube having one end to which a second connector connectable to the second fitting is attached and supplying the gas of the second pressure to a second body cavity of the subject; a single gas source supplying a gas used for supply of the gas of the first and second pressures; a gas supply unit controlling the gas supplied from the gas source to provide both of the first and second fittings with both of the gases of the first and second pressures, respectively; a sensor detecting information indicative of a condition of the first connector connected to the first fitting and information indicative of a condition of the second connector connected to the second fitting; a determination unit determining whether or not the first connector is correctly connected to the first fitting, determining whether or not the second connector is correctly connected to the second fitting, determining whether or not the second connector is connected to the first fitting when determining that the first connector is not connected to the first fitting, and determining whether or not the first connector is connected to the second fitting when determining that the second connector is not connected to the second fitting, based on the information from the sensor; and a gas supply control unit controlling, based on a result determined by the determination unit, the gas supply unit to supply the gas of the first pressure and the gas of the second pressure; wherein when the determination unit determines that the first connector is correctly connected to the first fitting, the gas supply control unit controls the gas supply unit to supply the gas of the first pressure to the first fitting, when the determination unit determines that the second connector is correctly connected to the second fitting, the gas supply control unit controls the gas supply unit to supply the gas of the second pressure to the second fitting, when the determination unit determines that the second connector is connected to the first fitting, the gas supply control unit controls the gas supply unit to supply the gas of the second pressure to the first fitting, and when the determination unit determines that the first connector is connected to the second fitting, the gas supply control unit controls the gas supply unit to supply the gas of the first pressure to the second fitting. 2. The gas supply apparatus according to claim 1, wherein both of the first and second fittings are formed on a surface of a casing of the gas supply apparatus, whereby an operator manually operates to connect both of the first and second connectors to both of the first and second fittings, respectively. 3. The gas supply apparatus according to claim 1, wherein the gas supply control unit issues a command to allow the gas of the first pressure to be supplied to the first fitting in a case where the determination unit determines that the first connector is correctly connected to the first fitting, issues a command to prohibit the gas of the first pressure from being supplied to the first fitting in a case where the determination unit determines that the first connector is not connected to the first fitting, issues a command to allow the gas of the second pressure to be supplied to the second fitting in a case where the determination unit determines that the second connector is correctly connected to the second fitting, issues a command to prohibit the gas of the second pressure from being supplied to the second fitting in a case where the determination unit determines that the second connector is not connected to the second fitting; issues a command to allow the gas of the second pressure to be supplied to the first fitting in a case where the determination unit determines that the second connector is connected to the first fitting, and issues a command to allow the gas of the first pressure to be supplied to the second fitting in a case where the determination unit determines that the first connector is connected to the second fitting. 4. The gas supply apparatus according to claim 3, further comprising a display unit informing an erroneous connection when the determination unit determines that the first connector is not connected to the first fitting or the second connector is not connected to the second fitting. 5. The gas supply apparatus according to claim 1, wherein the sensor includes a resistor with conductive contact portions at both ends thereof arranged on either the first fitting or the first connector and on the second fitting or the second connector, respectively; and conductive contact portions arranged on the remaining one of the first fitting and the first connector and on the remaining one of the second fitting and the second connector, respectively, and allowed to touch the contact portions of the resistor when being connected, and the determination unit performs the determination, at each of the first and second fittings, on the basis of results obtained when current is made to flow through the resistor via the contact portions on both the first and second fittings and the first and second connectors. 6. The gas supply apparatus according to claim 5, further comprising positioning means for positioning both the first connector connected to the first fitting and the second connector connected to the second fitting. 7. A method of managing connections of tubes arranged in a gas supply apparatus, comprising steps of: detecting a connected condition of a first tube connected to a first fitting through which a gas of a first pressure is discharged; detecting a connected condition of a second tube connected to a second fitting through which a gas of a second pressure is discharged; determining whether or not the first connector is correctly connected to the first fitting; determining whether or not the second connector is correctly connected to the second fitting; determining whether or not the second connector is connected to the first fitting when determining that the first connector is not connected to the first fitting; determining whether or not the first connector is connected to the second fitting when determining that the second connector is not connected to the second fitting; issuing a command to allow the gas of the first pressure to be supplied to the first fitting in a case where it is determined that the first connector is correctly connected to the first fitting, while issuing a command to prohibit the gas of the first pressure from being supplied to the first fitting in a case where it is determined that the first connector is not connected to the first fitting; issuing a command to allow the gas of the second pressure to be supplied to the second fitting in a case where it is determined that the second connector is correctly connected to the second fitting, while issuing a command to prohibit the gas of the second pressure from being supplied to the second fitting in a case where it is determined that the second connector is not connected to the second fitting; issuing a command to allow the gas of the second pressure to be supplied to the first fitting in a case where it is determined that the second connector is connected to the first fitting; and issuing a command to allow the gas of the first pressure to be supplied to the second fitting in a case where it is determined that the first connector is connected to the second fitting. 8. The managing method according to claim 7, further comprising a step of performing display notifying an erroneous connection when it is determined that the first connector is not connected to the first fitting or the second connector is not connected to the second fitting.
