Failsafe system and method for a medical fluid procedure

A failsafe method for a medical fluid procedure, comprising:

• providing 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;
• providing a disposable fluid circuit configured to associate with the medical fluid processing apparatus and comprising a tubing segment configured to fit within the sealer;
• and
• activating the sealer and sealing the tubing segment via the programmable controller in response to an occurrence of the failure event.

A failsafe system for a medical fluid procedure, comprising:

• a medical fluid processing apparatus comprising at least one of an apheresis machine, a dialysis machine, a device configured to administer a medicament, and an infusion device, comprising a radio frequency sealer in communication with a reader and a programmable controller driven by software, wherein the programmable controller is programmed to recognize from input from hardware components of the medical fluid processing apparatus a failure event comprising at least one of a leakage in a component of the fluid circuit, abnormal hematocrit, low blood volume, procedure pause event, procedure termination event, and failure to detect an authentication mark;
• a disposable fluid circuit configured to associate with the medical fluid processing apparatus and comprising a tubing segment incorporating an authentication mark recognizable by the reader and configured to fit within the radio frequency sealer, wherein the tubing segment is disposed between a first and second interference comprising at least one of a y-connection, port, clamp, pump raceway, valve, and pressure sensor when the disposable fluid circuit is in association with the medical fluid processing apparatus, wherein the first and second interferences are disposed at a distance of 2.0 in. or less with respect to each other along the tubing segment;
• wherein the programmable controller is configured to:
• proceed with the medical fluid procedure only when the tubing segment is detected within the radio frequency sealer;
• and
• seal the tubing segment by activating the radio frequency sealer surrounding the tubing segment in response to an occurrence of the failure event.
