Verification method and system for medical treatment
First Claim
1. A system for the collection, treatment and delivery of a blood sample, the system comprising:
- an article for association with a patient having a patient identifier;
a first syringe having;
a first syringe inlet for drawing an untreated blood sample from the patient, a first fluid chamber for receiving the untreated blood, a first syringe outlet for dispensing the untreated blood sample from the first chamber, a first incremental counter for recording temporal data corresponding to untreated blood events related to the collection of blood, the first syringe being associated with a first unique identifier correlatable to the patient identifier;
a vessel for processing the blood sample, the vessel having;
a blood sample processing chamber, the vessel having a chamber inlet;
the first syringe outlet being operable to establish a dedicated first fluid coupling with the chamber inlet to dispense the untreated blood sample to the blood sample processing chamber;
the vessel having a chamber outlet for dispensing a treated blood sample following treatment to a second syringe, the second syringe having;
a second syringe inlet operable to form a dedicated second fluid coupling with the chamber outlet to receive the blood sample from the blood sample treatment chamber;
a second chamber for receiving the treated blood;
a second syringe outlet;
a passage in communication with the second chamber and the second syringe outlet;
a second incremental counter for recording temporal data corresponding to blood treatment events, treated blood events and delivery events;
the second incremental counter being operable independently of the first incremental counter and being non-synchronized with the first incremental counter;
the second syringe being associated with a second unique identifier, the second unique identifier operatively associated with the first syringe and correlatable to the first unique identifier;
a releasable lock formed within the passage for operating the second syringe outlet between a plurality of states;
a processor having;
a comparator for comparing the patient identifier to the first unique identifier to determine the correlation between same; and
comparing the second unique identifier to the patient identifier to determine the correlation between same, the comparator issuing an output signal;
logic for receiving the output signal and the temporal data to determine time delays between the events and for determining whether the time delays are within predefined ranges;
a release signal generator coupled to the logic for issuing a release signal to the releasable lock;
whereby the release signal is issued upon confirmation of the correlation between the patient identifier and the first unique identifier, and the correlation between the patient identifier and the second unique identifier, and provided that the time delays are within predetermined ranges.

Abstract
A system for the collection, treatment and delivery of an autologous blood sample, comprising a first syringe for drawing an untreated blood sample from a patient, a blood sample treatment chamber having a chamber inlet for receiving untreated blood from the first syringe and chamber outlet for passage of treated blood to a second syringe coupled thereto. The second syringe includes a releasable lock means for allowing discharge of the treated blood to the patient in response to a release signal. The release signal is issued following a positive outcome from a verification process dependent upon temporal data from certain events in the collection, treatment and delivery of the blood sample, and identity data of the patient and the second syringe with the treated blood.

25. A method of monitoring a material sample from a patient, comprising the steps of:
-
(a) collecting the sample from the patient with a first collection device;
(b) associating the patient with a first signal carrying data representative of the sample;
(c) associating the first collection device with a second signal carrying data representative of the sample;
(d) delivering the sample to a sample treatment chamber;
(e) processing the sample to form a processed sample;
(f) collecting the sample in a second collection device;
(g) associating the second collection device with a third signal carrying data representative of the processed sample;
(h) comparing the data in the first and third signals to link the processed sample with the patient; and
thereafter(i) associating at least one of the steps (a) to (h) with temporal data;
(j) determining at least one time delay using said temporal data to determine whether said at least one of the steps (a) to (h) occurs within an acceptable time limit;
(k) delivering the processed sample to the patient upon a positive outcome from step (h) and step (j); and
(l) assembling an audit record having temporal data collected from step (i), the outcome from step (h) and step (j), and data associated with the sample.
