The condensate trap comprises an interior; a first connection for connecting the interior in fluid communication to a gas outlet of the blood treatment apparatus; a second connection for connecting the interior in fluid communication to a gas inlet of the blood treatment apparatus; and a third connection for connecting the interior to an air port of a blood treatment device. The blood treatment device may be, for example, a blood tubing set or a blood cassette. ## Claims ### Claim 1 A medical condensate trap for use in a blood treatment performed externally using a blood treatment apparatus, wherein the condensate trap comprises: an interior; a first connector structured to connect with tubing and defining a first port on a first surface of a housing of the condensate trap, wherein the first port is fluidly coupled with the interior, and wherein the first connector is configured to connect the interior to a gas outlet of the blood treatment apparatus in fluid communication; a second connector structured to connect with tubing and defining a second port on a second surface of the housing, wherein the second port is fluidly coupled with the interior, wherein the second connector is configured to connect the interior to a gas inlet of the blood treatment apparatus in fluid communication; and a third connector structured to connect with tubing and defining a third port on a third surface of the housing, wherein the third port is fluidly coupled with the interior, wherein the third connector is configured to connect the interior to an air port of a blood treatment device; wherein: the condensate trap is configured to dehumidify at least one section of the blood treatment apparatus or the blood treatment device without the use of a filter; the second surface of the housing and the third surface of the housing are spaced apart and are parallel to each other; and and the first surface extends between the second surface of the housing and the third surface of the housing and is generally perpendicular to the second surface of the housing and the third surface of the housing. ### Claim 2 (depends on 1) The medical condensate trap according to claim 1, wherein the condensate trap is configured to be used in an orientation in which the third port is arranged higher than the first port and the second port. ### Claim 3 (depends on 1) The medical condensate trap according to claim 1, wherein the condensate trap is configured to be used in an orientation in which the third port is arranged higher than the first port or the second port. ### Claim 4 (depends on 1) The medical condensate trap according to claim 1, wherein the condensate trap is configured to be used in an orientation in which the first port is arranged higher than the second port. ### Claim 5 (depends on 1) The medical condensate trap according to claim 1, wherein the third port is associated with a first end area of the interior, wherein the second port is associated with a second end area of the interior, wherein the second end area is opposite to the first end area, and wherein the first port is arranged between the second port and the third port. ### Claim 6 (depends on 1) The medical condensate trap according to claim 1, wherein the interior is separated by the housing from an exterior of the condensate trap, wherein the interior has an extension in a longitudinal direction and an extension in a transverse direction, and wherein the housing comprises: at least a first opening fluidly connected with the interior through the first port; at least a second opening fluidly connected with the interior through the second port; and at least a third opening fluidly connected with the interior through the third port. ### Claim 7 (depends on 6) The medical condensate trap according to claim 6, wherein the distance between the first opening and the third opening is greater than or equal to the extension in the transverse direction. ### Claim 8 (depends on 6) The medical condensate trap according to claim 6, wherein the distance between the first opening and the second opening is greater than or equal to the extension of the interior in the transverse direction. ### Claim 9 (depends on 6) The medical condensate trap according to claim 6, wherein tubes, with an inner diameter, are connected to the first, second, and third ports, and wherein the inner diameter is less than the extension of the interior in the transverse direction. ### Claim 10 (depends on 6) The medical condensate trap according to claim 6, wherein a diameter, a surface, or a length of a surface of at least one of the first opening, the second opening, or the third opening, is smaller than the extension of the interior in the transverse direction. ### Claim 11 (depends on 1) The medical condensate trap according to claim 1, wherein the blood treatment device comprises a blood tubing set or a blood cassette. ### Claim 12 A blood treatment apparatus which comprises, or is connected to, a condensate trap, wherein the condensate trap comprises: an interior; a first connector structured to connect with tubing and defining a first port that is fluidly coupled with the interior, wherein the first connector is fluidly coupled to a gas outlet of the blood treatment apparatus; a second connector structured to connect with tubing and defining a second port that is fluidly coupled with the interior, wherein the second connector is fluidly coupled to a gas inlet of the blood treatment apparatus; and a third connector structured to connect with tubing and defining a third port that is fluidly coupled with the interior, wherein the third connector is fluidly coupled to an air port of a blood cassette or blood tubing of a blood treatment device; wherein the condensate trap is configured to dehumidify at least one section of the blood treatment apparatus or the blood treatment device without the use of a filter. ### Claim 13 (depends on 12) The blood treatment apparatus according to claim 12, wherein the blood treatment apparatus is embodied as a blood tubing set and a blood cassette.
