Definitions
- forward prime or “forward priming” should be understood to mean operating a pump such that liquid and/or air are pumped in the distal direction, such that the liquid and/or air are delivered to the outlet of the pump. It should be noted that during priming, the distal liquid line is temporarily disconnected from a patient to prevent air from being infused into the patient's body.
- proximal volume should be understood to mean the volume of the portion of the liquid path that begins at the liquid supply and ends at a proximal air sensor in the cassette.
- distal volume should be understood to mean the volume of the portion of the liquid path that begins at a distal air sensor in the cassette and ends at the distal outlet (end) of the distal liquid line.
- a deliverable volume per pump cycle in this embodiment is from 0-500 ⁇ l, with a preferred volume being about 333 ⁇ l.
- the cassette volume is 1170 ⁇ l, and the air trap volume within the cassette is 550 ⁇ l.
- the proximal volume is 305 ⁇ l, while the distal volume is 330 ⁇ l.
- autopriming a pump cassette is the process in which an infusion pump automatically draws a liquid (as a liquid or a mixture of air and liquid) from a liquid source (such as a proximally attached drug container or reservoir), expels the air inside the cassette, and primes the distal line with a volume of liquid.
- a liquid source such as a proximally attached drug container or reservoir
- the agitation and movement of air and liquid within the cassette tends to enable small air bubbles to become trapped in the cassette, by adhering to the walls of the air trap and pumping chamber.
- the surface tension of the inside walls of the cassette can capture a significant amount of these small air bubbles.
- the plunger movement is halted once the proximal volume is filled with liquid, to ensure that the next pump cycle will deliver sufficient liquid to form liquid layer 110b.
- proximal air sensor 16 if proximal air sensor 16 has not monitored three steps of liquid by the time that the plunger has returned to the home position, the logic then returns to block 54, and the logical steps described by blocks 54, 56, 58, and 60 are repeated until three steps of liquid have been detected. Once three steps of liquid have been monitored by proximal air sensor 16, the logic proceeds to a block 64. As noted above, in block 64 pump control unit 32 stops the retraction of the plunger towards the home position, closes inlet valve 22 and opens outlet valve 26. At this point, no drop of liquid has been formed in air trap 20, but the proximal volume has been filled with liquid.
- Phase II begins at a start block 78.
- the logic proceeds to a block 79, wherein pump control unit 32 retracts the plunger. At this time, the plunger is retracted for a total movement of 250 steps (the extra long stroke described above). Note that this plunger retraction represents an intake stroke. Air trap 20 should be completely full of liquid, ensuring that a sufficient liquid layer 110b exists to prevent air bubbles from migrating into pumping chamber 24.
- the logic then proceeds to a block 80, where pump control unit 32 closes inlet valve 22 and opens outlet valve 26 (also ensuring that supply valve 14 is in its open position, as it already should be).
- the logic then proceeds to a block 82, and pump control 32 extends the plunger to the + 169 step position.
- FIGURE 6 illustrates the logical steps implemented to execute Phase III of the autoprime sequence, which delivers a fixed volume of liquid through outlet valve 26, removing air from pumping chamber 24 and the distal volume, thereby completing the autoprime sequence.
- the process begins at a start block 92.
- the logic proceeds to a block 94, and pump control unit 32 closes inlet valve 22 and opens outlet valve 26 (note that supply valve 14 remains in its open position).
- the logic then proceeds to a block 96, where pump control 32 extends the plunger to the + 169 steps position, thereby distally delivering any fluid from within pumping chamber 24.
- the logic continues with a block 98, in which pump control unit 32 closes outlet valve 26 and opens inlet valve 22.
- An alternative to delivering substantially more liquid than required would be for pump control 32 to calculate the number of steps required to deliver the deficient volume, and to extend the plunger only by that number of steps, as opposed to a full 169 steps during the delivery stroke of the next pump cycle.
- 35 steps will deliver 68.95 ⁇ l, so pump control 32 can limit the plunger extension to 35 steps to ensure that sufficient volume is delivered, while minimizing wastage of medicinal liquid.
