Abstract
An improved method for bending an oximeter sensor which simplifies the manufacturing. The sensor is manufactured without a bend, but when it is packaged for shipping, it is bent and restrained in the bent position. The sensor is made of a material which has memory so that when the packaging which restrains it is removed for use, the sensor will retain a partially bent shape.
Claims11
A method for packaging an oximeter sensor having a sensor rod connected to a sensor, comprising the steps of:
- forming said sensor rod from a material which has memory;
- bending said sensor rod more than amount of desired bending;
- restraining said sensor rod in a bent position with a restraining material;
- and
- packaging and shipping said sensor;
- such, that after being shipped said sensor can be unpacked and will expand to a partially bent position upon removal of said restraining material.
A method for packaging an oximeter sensor having a sensor rod connected to a sensor, wherein said sensor rod includes a channel for inserting a stylet, comprising the steps of:
- forming said sensor rod from a material which has memory;
- only partially inserting said stylet so that it is not bent when said sensor rod is bent;
- bending said sensor rod more than the amount of desired bending;
- restraining said sensor rod in a bent position with a restraining material;
- wherein said sensor rod is bent between 150 and 210 degrees and is made of a plastic having a plastic memory sufficient to retain a bend of between 45 and 120 degrees after unrestraining said sensor rod;
- and
- packaging and shipping said sensor;
- such that after being shipped said sensor can be unpacked and will expand to a partially bent position upon removal of said restraining material.
