Abstract
A system for delivering sterile fluid to a patient, while preventing cross-contamination, in which flow interrupting means are provided which basically create regions where no fluid exists in the comprehensive or over-all quality of material that is flowing from a fluid source to a patient.
Claims15
A disposable device for use with a system for delivering sterile fluid from a fluid source, to a plurality of patients, the disposable device comprising:
- flow interrupting means for causing flow of the sterile fluid to be substantially discontinuous so that fluid free gaps exist in the disposable device
- when there is substantially no forward flow, to preclude cross-contamination of the fluid source,
- wherein the flow interrupting means comprises a receptacle having an inlet and an outlet,
- the inlet being arranged to cause inflowing fluid to impinge on an internal surface of the receptacle at such an angle that the fluid flows along a wall of the receptacle,
- the outlet being arranged to remove fluid collected in the receptacle.
A reusable fluid path element configured as part of a fluid delivery path for use with a system for delivering sterile fluid from a fluid source to a plurality of patients, the reusable element comprising:
- an interface to connect the reusable fluid path element to the source of the sterile fluid;
- tubing to conduct the fluid from the fluid source to a disposable portion of the fluid delivery path;
- a mixing element provided along the fluid delivery path;
- and
- a backflow valve provided downstream of the mixing element, the backflow valve helping prevent cross-contamination between said plurality of patients.
A disposable device for use with a system for delivering sterile fluid from a fluid source to a plurality of patients, the disposable device comprising a flow interrupter that causes flow of the sterile fluid to be substantially discontinuous so that fluid free gaps exist in the disposable device when there is substantially no forward flow, to preclude cross-contamination of the fluid source, wherein the flow interrupter comprises a receptacle having an inlet and an outlet, the inlet being arranged to cause inflowing fluid to impinge on an internal surface of the receptacle at such an angle that the fluid flows along a wall of the receptacle, the outlet being arranged to remove fluid collected in the receptacle.
