I've always thought of the Braun Perfusor Compact as a portable pump rather then an ambulatory one (i.e. one which can be 'worn') though as Tracy points out it should be considered if only because of the battery life.
Roy has hit the nail on the prverbial head in mentioning the key attributes for an ambulaory pump. However, in my previous life I put together the spec for such a pump (the Advancia MS) and we found very quickly that the force required to push a 1ml syringe was too great for any motor available that would make the pump ambulatory. We could only just get good performance out of the better 2ml syringes.
Bottom line is that you will never see an ambulatory pump as small as an MS 16a or 26 with all the requisite safety and performance features (accuracy, time to occlusion etc) that takes disposable syringes....because the syringes are part of the problem too.
Shame the Advancia will never see the light of day because it really could have moved the safety bar up to where it should be in ambulatory infusion....however....there is another....so an old "Colleague"
told me!!
