Abstract

A method and a system for determining analyte content in a fluid in a treatment apparatus. The method comprises positioning a device for treatment in a treatment apparatus. A surface of the device is contacted with a fluid. An analyte content in the fluid is determined based on an electromagnetic property of the fluid following contacting the surface of the device with the fluid. More specifically, an electromagnetic property is measured. The measuring comprises emitting electromagnetic radiation into the fluid in the treatment apparatus and detecting electromagnetic radiation from the fluid. In another aspect, a system comprising a treatment apparatus and a detector for determining the analyte content in the fluid in the treatment apparatus is provided.

First claim

1 . (canceled)

2 . A method for treating a medical device in a treatment apparatus, comprising:
positioning the medical device in the treatment apparatus; contacting a surface of the medical device with a fluid; after the contacting step, emitting electromagnetic radiation into the fluid; after the emitting step, detecting an electromagnetic property from the fluid to determine an analyte content in the fluid; based upon the analyte content, adjusting a treatment agent included in the fluid and continuing the treatment process, or ending the treatment process.

3 . The method of claim 2 , wherein the electromagnetic property comprises at least one of absorbance, transmittance, scattering, photoluminescence, and reflectance.

4 . The method of claim 2 , wherein the analyte content is at least one of a concentration, a particle size, and a particle distribution.

5 . The method of claim 2 , further comprising introducing a reagent to the fluid, wherein the reagent comprises an electromagnetic property responsive to contact with analyte.

6 . The method of claim 5 , wherein the reagent comprises at least one of bicinchoninic acid (BCA) reagent, Coomassie reagent, ninhydrin reagent, ortho-phthalaldehyde (OPA) reagent, and fluorescamine reagent.

7 . The method of claim 2 , wherein contacting the surface of the medical device comprises at least one of spraying the medical device with the fluid, submerging the medical device in the fluid, and flowing the fluid over the surface of the medical device.

8 . The method of claim 2 , wherein the surface of the medical device comprises analyte and wherein contacting the surface of the medical device in the treatment apparatus with the fluid comprises transferring at least a portion of the analyte from the medical device to the fluid.

9 . The method of claim 2 , wherein the analyte comprises at least one of a protein, a carbohydrate, a lipid, a peptide, a nucleic acid, a polynucleotide, a bacterium, a virus, a spore, a eukaryote, an archaean, and a treatment agent.

10 . The method of claim 2 , wherein positioning the medical device in the treatment apparatus further comprises placing the medical device in fluid communication with the treatment apparatus.

11 . The method of claim 2 , wherein contacting the surface of the medical device in the treatment apparatus with the fluid comprises contacting a luminal surface of medical device with the fluid.

12 . The method of claim 2 , wherein the fluid comprises at least one of water and a treatment agent.

13 . The method of claim 11 , wherein the treatment agent is a surfactant and the fluid comprises at least 0.01% surfactant by weight based on a total weight of the fluid.

14 . The method of claim 2 , further comprising, based upon the analyte content, adjusting at least one of a treatment temperature and a treatment pressure.

15 . The method of claim 14 , wherein adjusting the treatment temperature increases removal of at least one of debris and bioburden from the surface of the medical device.

16 . The method of claim 15 , wherein adjusting at least one of the treatment agent, the treatment temperature and the treatment pressure is based upon an average value of analyte content from a plurality of locations on the device.

17 . The method of claim 2 , wherein the medical device is at least one of an endoscope, forceps, a clamp, a retractor, a cutter, a dilator, a tube, a fitting, a stapler, a needle, a drill, a scope, and a probe.

18 . A method for treating a medical device in a treatment apparatus, comprising:
positioning the medical device in the treatment apparatus; contacting a surface of the medical device with a fluid; after the contacting step, emitting electromagnetic radiation into the fluid; after the emitting step, detecting electromagnetic radiation from the fluid to determine an analyte content in the fluid; based upon the analyte content, adjusting a treatment agent included in the fluid and continuing the treatment process, or ending the treatment process.

19 . The method of claim 18 , wherein detecting electromagnetic radiation comprises detecting at least one of emitted electromagnetic radiation and secondary electromagnetic radiation from the fluid.

20 . The method of claim 19 , wherein determining the analyte content in the fluid further comprises comparing the emitted electromagnetic radiation and the detected emitted electromagnetic radiation.

21 . A method for treating an endoscope in a treatment apparatus, comprising:
positioning the endoscope in the treatment apparatus; contacting a surface of the endoscope with a fluid; after the contacting step, detecting an electromagnetic property from the fluid to determine an analyte content in the fluid; based upon the analyte content, adjusting a treatment agent and continuing the treatment process, or ending the treatment process.
