Abstract
A failsafe system for a medical fluid procedure, comprising a medical fluid processing apparatus comprising a sealer and a programmable controller driven by software, wherein the programmable controller is programmed to recognize a failure event from input from hardware components of the medical fluid processing apparatus. The system also comprises a disposable fluid circuit configured to associate with the medical fluid processing apparatus and comprising a tubing segment configured to fit within the sealer. The programmable controller is configured to seal the tubing segment by activating the sealer surrounding the tubing segment in response to an occurrence of the failure event.
Claims21
A medical fluid processing apparatus, comprising:
- a sealer configured to receive at least a portion of a tubing segment of a fluid flow circuit, the sealer including an authentication system comprising one or more transponders included within the sealer and configured to authenticate the fluid flow circuit;
- and
- a controller configured to receive input from the authentication system and, upon receiving input from the authentication system indicative of a failure to authenticate the fluid flow circuit, activate the sealer to seal said at least a portion of the tubing segment received by the sealer, so as to render the fluid flow circuit unusable.
A failsafe method for a medical fluid procedure, comprising:
- providing a medical fluid processing apparatus comprising a sealer including an authentication system comprising one or more transponders included within the sealer;
- mounting a fluid flow circuit to the medical fluid processing apparatus, with at least a portion of a tubing segment of the fluid flow circuit received by the sealer;
- attempting to authenticate the fluid flow circuit using the authentication system;
- and
- activating the sealer to seal said at least a portion of the tubing segment in response to a failure of the authentication system to authenticate the fluid flow circuit, so as to render the fluid flow circuit unusable.
A failsafe system for a medical fluid procedure, comprising:
- a disposable fluid flow circuit including a tubing segment;
- and
- a medical fluid processing apparatus configured as an apparatus selected from the group consisting of an apheresis machine, a dialysis machine, a device configured to administer a medicament, and an infusion device, comprising
- a radio frequency sealer receiving at least a portion of the tubing segment and including an authentication system comprising one or more transponders included within the radio frequency sealer, and
- a controller configured to receive input from the authentication system, wherein
- the radio frequency sealer is disposed between first and second interferences each selected from a group consisting of a y-connection, a port, a clamp, a pump raceway, a valve, and a pressure sensor and separated by a distance of 2.0 in. or less, and the controller is configured to
- proceed with the medical fluid procedure only when said at least a portion of the tubing segment is detected within the radio frequency sealer, and
- activate the radio frequency sealer to seal said at least a portion of the tubing segment in response to receipt of input from the authentication system indicative of a failure to authenticate the fluid flow circuit.
