Abstract

A safety interlock for use in a 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 on the medical device. The outer ring portion is formed of a light transmitting material and includes at least one interposing surface. A 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 device is adapted for mounting in medical device in a path of electromagnetic radiation from a source of electromagnetic radiation for reflecting the electromagnetic radiation to a electromagnetic radiation detector when properly loaded on the medical device.

Claims

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 on the medical device, the outer ring portion being formed of a light transmitting material and including at least one interposing surface; and

a 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 device being adapted for mounting in the medical device in a path of the electromagnetic radiation from the source of electromagnetic radiation for reflecting the electromagnetic radiation to the electromagnetic radiation detector when properly loaded on the medical device.

2. The safety interlock as set forth in claim 1 wherein the connector portion extends radially outward from the central ring portion and the outer ring portion extends generally transversely from the connector portion.

3. The safety interlock as set forth in claim 2 wherein the connector portion extends downwardly from the central ring portion at an angle.

4. The safety interlock as set forth in claim 3 wherein the outer ring portion extends generally parallel to the central ring portion.

5. The safety interlock as set forth in claim 1 wherein the central ring portion reflects the electromagnetic radiation from the source of electromagnetic radiation to the electromagnetic detector when the safety interlock is properly mounted in the medical device.

6. The safety interlock as set forth in claim 5 wherein the central ring portion is formed of a material that reflects electromagnetic radiation in the infrared range and blocks electromagnetic radiation in the visible range.

7. The safety interlock as set forth in claim 6 wherein the outer ring portion is formed of a material that transmits electromagnetic radiation in the infrared range.

8. The safety interlock as set forth in claim 7 wherein the outer ring portion blocks the transmission of electromagnetic radiation in the visible range.
