<p>An ambulatory disposable infusion pump has a preferably substantially transparent receiving and retaining housing (20) which may have indicia markings (23) conventionally applied to indicate quantity. The inflow of fluid causes an elastomeric member (56) attached to a piston (28) which is slideable in the housing to be stretched. The tension in the elastomeric member provides an energy source (force) to push the fluid out of the bore when the connected tubing line (40) is opened.</p> |
