A method of manufacturing a fluid collection apparatus having an integrated lance and reaction area. The method includes providing a sheet of material and then coating the sheet with a photoresist in a pattern on one side of the sheet. The pattern defines a lance and a reaction area. At least one side of the sheet is placed in a solvent. After corroding the sheet in areas not covered by the photoresist the sheet is removed from the solvent and reveals an integrated lance and reaction area.

Why it's free to use
- Filed February 19, 2003 and granted June 30, 2015. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 19, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 19, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
