1. A medical infusion system comprising:
a first device having first control electronics and having, or configured to operably couple to, (i) a first reservoir for housing a liquid composition comprising a medicament, (ii) a first pump mechanism configured to drive the liquid composition from the first reservoir to a patient, and (iii) a first input apparatus configured to receive input indicative of a patient side effect of the medicament, wherein the first control electronics are operably coupled to the first pump mechanism and to the first input apparatus, and wherein the first control electronics are configured:
(a) to cause the first pump mechanism to drive the liquid composition from the first reservoir to the patient for a first predetermined period of time at a rate increased relative to a first preceding rate if no input indicative of the patient side effect has been received during a period of time in which the first pump mechanism drove the liquid composition from the first reservoir to the patient at the first preceding rate; and
(b) to repeat step (a) until a maximum predetermined rate has been achieved or until input indicative of the patient side effect is received; and
a second device having second control electronics and having, or configured to operably couple to, (i) a second reservoir for housing amount of the liquid composition comprising the medicament, (ii) a second pump mechanism configured to drive the liquid composition from the second reservoir to the patient, and (iii) a second input apparatus configured to receive input indicative of the patient side effect of the medicament, wherein the second control electronics are operably coupled to the second pump mechanism and to the second input apparatus, and wherein the second control electronics are configured:
(c) to cause the second pump mechanism to drive the liquid composition from the second reservoir to the patient for a second predetermined period of time at a rate increased relative to a second preceding rate if no input indicative of the patient side effect has been received during a period of time in which the second pump mechanism drove the liquid composition from the second reservoir to the patient at the second preceding rate; and
(d) to repeat step (c) until a maximum predetermined rate has been achieved or until the second control electronics determine that input indicative of the patient side effect is received,
wherein the first and second pump mechanisms are the same or different,
wherein the first and second reservoirs are the same or different,
wherein the first and second input apparatuses are the same or different, and
wherein the first and second devices are configured to be employed by the patient sequentially such that the second device is employed by the patient to deliver the medicament after the first device is no longer being used to deliver the medicament, and
wherein the first device is configured to transmit to the second device data regarding a last rate at which the first pump mechanism was configured to drive the liquid composition from the first reservoir to the patient, and wherein the second control electronics are configured to set the last rate of the first pump mechanism as the initial rate of the second pump mechanism in step (c).
