Abstract
A tubing adapter for interconnection with a least one tubing section of a medical device, a dialysis fluid tubing system including such a tubing adapter, a medical device including such a dialysis fluid tubing system, and a method for avoiding a pressure within a dialysis fluid tubing system that is below a minimum pressure are described.
Claims19
A dialysis fluid tubing system, comprising:
- a first tubing section configured to interconnect with a heating device or comprising a heating bag;
- a pumping section configured to interconnect with a pump and arranged upstream of the first tubing section;
- and
- at least one of:
- (a) at least one tubing adapter comprising at least one of:
- (i) at least one locking mechanism for blocking a flow-through lumen;
- or
- (ii) a device for generating or amending a flow resistance of the at least one tubing adapter or of a second tubing section of the dialysis fluid tubing system connected to the at least one tubing adapter,
- wherein the at least one tubing adapter is configured to be arranged downstream of the first tubing section,
- wherein the at least one locking mechanism or the device for generating or amending a flow resistance is configured to prevent a pre-defined pressure upstream of the at least one tubing adapter,
- wherein the pre-defined pressure is a pressure below a pre-defined minimum pressure;
- and
- wherein the pre-defined minimum pressure is a pressure at which the first tubing section or the heating bag does not collapse;
- or
- (b) one tubing adapter integral with the dialysis fluid tubing system and comprising at least one of:
- (i) at least one locking mechanism for blocking a flow-through lumen;
- or
- (ii) a device for generating or amending a flow resistance of the one tubing adapter or of a second tubing section of the dialysis fluid tubing system connected to the one tubing adapter,
- wherein the one tubing adapter is arranged downstream of the first tubing section,
- wherein the at least one locking mechanism or the device for generating or amending a flow resistance is configured to prevent a pre-defined pressure prevailing upstream of the one tubing adapter,
- wherein the pre-defined pressure is a pressure below a pre-defined minimum pressure, and
- wherein the pre-defined minimum pressure is a pressure at which the first tubing section or the heating bag does not collapse.
