Intermittent fluid delivery apparatus and method
First Claim
1. An apparatus for delivering a fluid during a series of infusion intervals, consecutive infusion intervals being separated by a non-infusion interval, each infusion interval beginning at a predetermined time and having a first predetermined period, and each non-infusion interval beginning at a predetermined time and having a second predetermined period, the apparatus comprising:
- a pump mechanism; and
circuitry operatively connected to the pump mechanism, the circuitry being configured so that;
if the pump is disabled during one of the infusion intervals, the circuitry will determine the length of time the pump is disabled, interrupt the infusion interval while the pump is disabled, and delay the beginning of subsequent infusion and non-infusion intervals for a length of time approximately equal to the length of time the pump is disabled; and
if the pump is disabled and then enabled during the second predetermined period of one of the non-infusion intervals, begin the succeeding infusion interval at the predetermined beginning time.

Abstract
An apparatus and method for delivering a fluid during a series of infusion intervals, consecutive infusion intervals being separated by a non-infusion interval, each infusion interval beginning at a predetermined time and having a first predetermined period, and each non-infusion interval beginning at a predetermined time and having a second predetermined period. The apparatus comprises a pump mechanism and circuitry operatively connected to the pump mechanism. The circuitry is configured so that, if the pump is disabled during one of the infusion intervals, the circuitry will determine the length of time the pump is disabled, interrupt the infusion interval while the pump is disabled, and delay the beginning of subsequent infusion and non-infusion intervals for a length of time approximately equal to the length of time the pump is disabled. If the pump is disabled and then enabled during the second predetermined period of one of the non-infusion intervals, begin the succeeding infusion interval at the predetermined beginning time.

5. A method of delivering a fluid with a pump during a series of infusion intervals, consecutive infusion intervals being separated by a non-infusion interval, each infusion interval beginning at a predetermined time and having a first predetermined period, and each non-infusion interval beginning at a predetermined time and having a second predetermined period, the method comprising the steps of:
-
delivering the fluid during each infusion interval; if the pump is disabled during one of the infusion intervals, determining the length of time the pump is disabled, interrupting the infusion interval while the pump is disabled, and delaying the beginning of subsequent infusion and non-infusion intervals for a length of time approximately equal to the length of time the pump was disabled; and if the pump is disabled and then enabled during the second predetermined period of one of the non-infusion intervals, beginning the succeeding infusion interval at the predetermined beginning time. - View Dependent Claims (6, 7, 8)
