METHOD OF SAFE INFUSION

摘要

A lock-and-key apparatus (22) for use with an infusion-bag administration system, the apparatus including proximal and distal sides with respect to a user, first and second blocks (24, 26) arranged to be selectably joined and selectably locked together and having a first common interface between them when they are joined, and a lock-and-key mechanism (10). The lock-and-key mechanism (10) includes a lock (27), in communication with the first and second blocks (24, 26), for selectably locking them together and a key (29), located with the patient to whom an infusion is intended, for unlocking the lock (27). When a resilient portion of the infusion-bag administration system is arranged between the first and second blocks (24, 26), on the first interface, the locking of the first and second blocks (24, 26) together will prevent passage of the infusion liquid.
