Apparatus and method for measuring the amount of fluid contained in an implantable medical device |
摘要 |
An implantable pump apparatus and method of operating the implantable pump for infusing a fluid into a body are described. The implantable pump apparatus includes a support member. A pressure sensitive resistor member is disposed on a first side of the support member. A spring member includes a first end which is adjacent to the pressure sensitive resistor member. An expandable fluid reservoir member includes a first end which is adjacent to a second end of the spring member. The level of fluid within the expandable fluid reservoir member is determined by measuring a force applied to the pressure sensitive resistor member.
