1. A method of producing a pump set having a safety interlock member, the method comprising:
- forming visible light-absorbing polyenes in the safety interlock member without the use of colorant or dyes such that the safety interlock member allows transmission therethrough of radiation with a wavelength in a range of from about 750 nm to about 1,000 μ
m and blocks electromagnetic radiation in a visible light range of from about 380 nm to about 740 nm; and
connecting a tubing to the safety interlock member.

Abstract
A pump set for use in a liquid delivery pump of the type for delivering liquid to a patient, having an infrared radiation detector for detecting infrared radiation, and providing an indication that the pump set is properly loaded on the pump. The pump set comprises a conduit for the liquid and a safety interlock member which is carried by the conduit. The safety interlock member is formed of a material that transmits infrared radiation and blocks visible light.
