Safety interlock
First Claim
1. A safety interlock for use in a medical device having a control system for controlling operation of the medical device, a source of electromagnetic radiation operatively connected to the control system of the medical device for emitting electromagnetic radiation, and an electromagnetic radiation detector operatively connected to the control system for providing an indication that the safety interlock is properly loaded on the medical device, the safety interlock comprising:
- a central tubular portion defining a fluid passage for passing fluid through the safety interlock;
an outer ring portion adapted for mounting the safety interlock in the medical device; and
a spoked connector portion connecting the central tubular portion to the outer ring portion so that the outer ring portion is spaced radially outwardly from the central tubular portion in opposed relation with at least a portion of the central tubular portion;
the safety interlock being adapted for mounting in the medical device in a path of the electromagnetic radiation from the source of electromagnetic radiation such that the central tubular portion reflects the electromagnetic radiation to the electromagnetic radiation detector when properly loaded in the medical device.

Abstract
A safety interlock for use in a medical device having a control system for controlling operation of the medical device includes a central tubular portion defining a fluid passage for passing fluid through the safety interlock. An outer ring portion is adapted for mounting the safety interlock in the medical device. A spoked connector portion connects the central tubular portion to the outer ring portion so that the outer ring portion is spaced radially outwardly from the central tubular portion in opposed relation with at least a portion of the central tubular portion. The safety interlock is adapted for mounting in the medical device in a path of electromagnetic radiation from a source of electromagnetic radiation such that the central tubular portion reflects the electromagnetic radiation to a electromagnetic radiation detector when properly loaded on the medical device.
