First Claim
Patent Images
1. An orthopedic simulator having at least one test station with a specimen container for containing a fluid bath, comprising:
- a fluid level sensor positioned to sense the level of fluid in the fluid bath and generate a fluid level signal; and
a fill controller coupled to the fluid level sensor that controls filling of the fluid bath with replenishing fluid as a function of the fluid level signal.

Abstract
An orthopedic simulator is provided with an orthopedic simulator having at least one test station with a specimen container for containing a fluid bath, such as bovine fluid. A fluid level sensor is positioned to sense the level of fluid in the fluid bath and generate a fluid level signal. A fill controller is coupled to the fluid level sensor. The fill controller controls filling of the fluid bath with liquid, such as distilled water, as a function of the fluid level signal to restore and maintain the concentration of the bath.

23. An orthopedic simulator comprising:
-
a test station having a specimen container for containing a bath in which a test specimen is immersed during testing; and a fluid concentration maintenance arrangement in fluid communication with the specimen container to maintain a specific fluid concentration of the bath, the fluid concentration maintenance arrangement including a controller with settable indicators that cause an indication of a low fluid level of the bath, and a re-filling system operable by an operator in response to the indication to re-fill the specimen container with replenishing fluid.
