Apparatus for monitoring specific substances in a fluid
First Claim
1. An apparatus for monitoring specific substances in a fluid, comprising:
- a housing;
a tray disposed in said housing;
transmission means disposed in said housing for rotating said tray;
a cylindrical transparent reservoir held by said tray so that said cylindrical transparent reservoir synchronously rotates with said tray, said cylindrical transparent reservoir containing a fluid sample to be analyzed;
a cylindrical holder having a plurality of hollow frames formed around the surrounding thereof each of which holding a test paper having an unique color change in a predetermined location thereof sensitive to at least one specific substance in said fluid sample, said cylindrical holder disposed in said cylindrical transparent reservoir so that the level of said fluid sample contained in said cylindrical transparent reservoir exceeds the bottom of each said test paper and said fluid sample is absorbed by each said test paper by capillary action; and
an optical scanning assembly fastened beside said cylindrical transparent reservoir for capturing an image of a pattern displayed on each said test paper in response to said fluid sample upon rotating said cylindrical transparent reservoir, and converting the image to electronic signals, thereby the specific substances contained in said fluid sample are analyzed and identified via the image information captured from each said test paper.

Abstract
An apparatus for monitoring specific substances in a fluid is provided. The apparatus of the present invention includes a housing, a tray, transmission means, a cylindrical transparent reservoir, a cylindrical holder having a plurality of hollow frames around the surrounding thereof each of which holding a test paper, and an optical scanning assembly. The tray is disposed in the housing and rotated by the transmission means. The cylindrical transparent reservoir contains a fluid sample to be analyzed and is held on the tray so as to synchronously rotate with the tray. The cylindrical holder is disposed in the cylindrical transparent reservoir. The optical scanning assembly is fastened beside the cylindrical transparent reservoir for capturing an image of a pattern displayed on each test paper in response to at least one specific substance in the fluid sample upon rotating the cylindrical transparent reservoir and converting the image into electronic signals. Thereby, the specific substances in the fluid sample are analyzed and identified via the image information captured from each test paper.
