Medical treatment control system

A system for blood processing, comprising:

• a first syringe to receive a blood sample from a subject patient;
• a patient identifier attachable to the subject patient;
• blood treatment unit;
• a syringe carrier for transferring the first syringe containing the blood sample to the blood treatment unit, the syringe carrier being operable in a release position to receive the first syringe when the first syringe is in a blood-containing configuration, the syringe carrier being operable in a lock position for locking the first syringe therewith;
• access control means for controlling the release and lock positions to control access to the first syringe according to a blood sample transfer condition;
• a second syringe to receive the blood sample after treatment in the blood treatment unit to form a treated blood sample;
• the syringe carrier being operable in the release position to receive the second syringe when the second syringe is in a blood-containing configuration, the syringe carrier being operable in the lock position for locking the second syringe therewith;
• said access control means being operable to control the release and lock positions to control access to the second syringe according to a treated blood transfer condition.

A method of controlling the transfer of blood between a subject patient and a blood treatment unit, comprising the steps of:

• providing a first syringe containing a sample of untreated blood from a subject patient;
• providing a syringe carrier which is operable in a release position to receive the first syringe;
• the syringe carrier being operable in a lock position for locking the first syringe therewith, the carrier having an access controller for controlling the release and lock positions according to a blood transaction condition, the access controller including a data transfer unit which is operable to receive patient identification data representative of a subject patient;
• in a first blood transaction step, delivering patient identification data representative of a subject patient to the data transfer unit, thereby to place the syringe carrier in a release position to receive the first syringe and thereafter to place the syringe carrier in a lock position to lock the first syringe therein;
• in a second blood transaction condition, transferring the patient identification data to a blood treatment unit, thereby to place the syringe carrier in the release position to release the first syringe to a first syringe station in the blood treatment unit;
• in a third blood transaction step, delivering treated blood identification data from the blood treatment unit to the syringe carrier, and delivering treated blood verification data from a second syringe containing treated blood from the subject patient and which is positioned at a second syringe station in the blood treatment unit, and placing the syringe carrier in the release position to receive the second syringe;
• in a fourth blood transaction step, delivering patient verification data to the syringe carrier and placing the syringe carrier in the release position to release the second syringe.

A method of controlling the transfer of blood between a subject patient and a blood treatment unit, comprising the steps of:

• providing a first syringe to receive a sample of untreated blood from a subject patient;
• providing the subject patient with a patient RF signal processor;
• providing a second syringe to receive the sample following treatment;
• providing each of the first syringe and the second syringe with an RF signal processor;
• arranging the RF signal processors on the first syringe and with the patient to issue a signal containing common or related identity data;
• delivering the first syringe to the blood treatment unit for performing a treatment step to form a treated blood sample;
• reading the identity data from the first syringe and writing the identity data to the second syringe;
• collecting the treated blood sample from the treatment unit in the second syringe;
• bringing the second syringe within range of the patient RF signal processor to confirm a match therebetween;
• and thereafter
• delivering the treated blood sample to the patient.
