My partner has a walkmed pump and when he primes it for a bolus it gives off a beep and says there is an occlusion in the line. We keep checking the cord but the lines look fine. He has already ended up in the hospital as his last pump stopped working. He says it is still delivering the bolus but it will only prime for ten seconds at a time before the occ alarm starts. We then have to press stop and then start to get the occ signal to stop and the pump to start delivering again. Do you have any ideas why this may be happening? It is Friday and we cant contact the palliative care team to ask them for help until Monday. Please help us
