Safety interlock for a medical device

摘要

A safety interlock (61) for use in a medical device (1) having a control system (77) for controlling operation of the medical device includes a central tubular portion (83,89) defining a fluid passage (81) for passing fluid through the safety interlock. An outer ring portion (88) is adapted for mounting the safety interlock in the medical device. A spoked connector portion (87) 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 (105) such that the central tubular portion reflects the electromagnetic radiation to a electromagnetic radiation detector (109) when properly loaded on the medical device.
