Abstract
A radiation dose sensor that measures a radiation dose of a biocontainer formed for a first material includes a first electrode, a second electrode, and a film. The first electrode has a plurality of first fingers. And the second electrode has a plurality of second fingers. The fingers of the first electrode extend towards and are interdigitated with the fingers of the second electrode that extend towards the first electrode with gaps formed between the first and second fingers. The film coats the interdigitated fingers and is disposed within the gaps. The film is formed of a second material that is similar to the first material that forms the biocontainer.
Claims20
A radiation dose sensor for measuring a radiation dose of a biocontainer formed of a first material, the radiation dose sensor comprising:
- a first electrode having a plurality of first fingers;
- a second electrode having a plurality of second fingers, the plurality of first fingers extending from the first electrode towards the second electrode, the plurality of second fingers extending from the second electrode towards the first electrode such that the first fingers are interdigitated with the second fingers with gaps defined between the first fingers and the second fingers;
- and
- a film coating the plurality of first fingers and the plurality of second fingers such that the film is disposed within the gaps, the film formed of a second material similar to the first material forming the biocontainer, the film configured to degrade when exposed to radiation to determine a radiation dose of the sensor.
A method of manufacturing a radiation dose sensor, the method comprising:
- interdigitating fingers of a first electrode with fingers of a second electrode;
- and
- coating the interdigitated fingers with a material to form a film over the interdigitated fingers such that the film is disposed within gaps defined between the fingers of the first electrode and the fingers of the second electrode, the material of the film being selected to be similar to a material forming a biocontainer associated with the radiation dose sensor, the film configured to degrade when exposed to radiation to measure a dose of radiation.
A method of predicting a change impact of a biocontainer due to irradiation thereof, the method comprising:
- associating a radiation dose sensor with a biocontainer, the radiation dose sensor including a film formed of a material similar to a material forming the associated biocontainer;
- irradiating the radiation dose sensor and the biocontainer such that the film degrades;
- and
- predicting the change impact of irradiation on the biocontainer based on the irradiation of the radiation dose sensor.
A kit comprising:
- a package;
- a first sterilized biocontainer disposed in the package, the first sterilized biocontainer formed of a first material;
- and
- a first sensor disposed in the package, the first sensor comprising:
- a first electrode having a plurality of first fingers;
- a second electrode having a plurality of second fingers, the plurality of first fingers extending from the first electrode towards the second electrode, the plurality of second fingers extending from the second electrode towards the first electrode such that the first fingers are interdigitated with the second fingers with gaps defined between the first and second fingers;
- and
- a film coating the plurality of first fingers and the plurality of second fingers such that the film is disposed within the gaps, the film formed of the first material forming the first sterilized biocontainer, the film configured to degrade when exposed to radiation to determine a radiation dose of the sensor.
