We examined the effects of the sizes of the inlet port and the outlet port of the pump on its output characteristics. The maximum output power can be obtained at the diameter of the inlet port of 12mm and at the width of the outlet port of 5mm. The most critical part of the pump in durability is the seal membrane. Therefore stress distribution in the seal membrane was analyzed using Finite Element Method. It was revealed by these analysis that the maximum tensile and compressive stresses were generated around the junction of the oscillating rod. About eighty percent of these maximum stress was due to the deformation by the declining of the oscillating rod. About twenty percent of them was due to the torsional moment of the rod. Less than one percent of them was due to the pressure in the blood chamber.
