Apparatus and method for handling fluid samples of body materials
First Claim
1. An apparatus for analyzing a body fluid specimen held in a first container and using a treating fluid retained in a second container to enhance the observation of the fluid specimen, comprising:
- a slide assembly having first and second separate fluid specimen retaining optical viewing chambers;
said viewing chambers each having first and second ports;
a pump having a first port and a second port;
first tubing means effectively coupling the first port of the pump to the first ports of the viewing chambers of said slide assembly;
a fluid mixing function;
second tubing means for coupling the second port of one of the viewing chambers through said fluid mixing function to both said fluid specimen in said first container and to said treating fluid in said second container;
third tubing means for coupling the second port of said second viewing chamber to the specimen in said first container;
whereby, in response to a pumping action of said pump from its first port to its second port, fluid specimen is drawn from said first container to be mixed by said mixing function with said treating fluid drawn from said second container to deliver a treated specimen fluid into said first viewing chamber and provide a fluid specimen for viewing in said second viewing chamber.

Abstract
A system for handling a body specimen is described for particular use in the handling of fecal specimen which are to be treated with a stain for enhancing its visibility. The system includes dual optical viewing chambers mounted alongside of each other on a frame with appropriate tubing connecting ports of the viewing chambers to a liquid specimen supply and the satin supply. The stain supply is connected to one of the tubings leading to a viewing chamber so that the drawing action from a pump connected to ports on the other side of the viewing chambers can force an automatic mixing of the staining solution with one of the liquid specimen being drawn into one of the viewing chambers. Controls and techniques for operating the system are described.

9. An apparatus for analyzing a body substance held in a first container as a liquid specimen with a staining solution held in a second container and using a flushing liquid stored in a third container, comprising:
-
a slide assembly having first and second liquid specimen retaining optical viewing chambers;
said viewing chambers having first and second ends;first means for coupling first ends of said viewing chambers to said first container so as to enable liquid specimen to be passed into the viewing chambers; second means for coupling the second container to a first end of one of said liquid specimen retaining optical viewing chambers to provide a staining solution therein mixed with said specimen solution; third means for coupling the flushing liquid in the third container to the second ends of said first and second liquid specimen retaining optical viewing chambers; means for controlling the flow of liquid specimen and said staining solution through said first and second viewing chambers so as to deliver an unstained liquid specimen for viewing in one of said viewing chambers and for causing a stained liquid specimen for viewing in said other viewing chamber; and means for controlling the flow of said flushing liquid through said second ends of the viewing chambers to cleanse them in preparation for viewing of another liquid specimen. - View Dependent Claims (10, 11, 12, 13)

14. A method for handling a specimen fluid stored within a container and requiring treatment with a treating liquid for viewing inside an optical viewing chamber, comprising the steps of:
drawing a first sample of the specimen fluid so as to pass through a tube into a first viewing chamber and, while the first sample is moving through the tube, having the drawing action of the first sample draw a sample of said treating liquid through a junction into said tube so as to form a mixture with the specimen fluid within the tube and while continuing said drawing step moving the mixture to the first viewing chamber for observation of the mixture therein. - View Dependent Claims (15, 16)

17. A slide assembly for holding a liquid specimen comprising:
-
a pair of elongate transparent extruded glass seamless enclosures, each enclosure having an upper transparent wall for viewing a liquid specimen and each enclosure having ports to enable the introduction and purging of fluid; a slide assembly holder;
said enclosures being mounted in side by side relation ship on said holder.

19. An apparatus for analyzing a body fluid specimen held in a first container and using a treating fluid retained in a second container to enhance the observation of the fluid specimen, comprising:
-
a slide assembly having a fluid specimen retaining optical viewing chamber;
said viewing chamber having first and second ports; and
a pump having a first port and a second port,first tubing means for effectively coupling the first port of the pump to the first port of the viewing chamber of said slide assembly; a fluid mixing junction; second tubing means for effectively coupling the second port of said viewing chamber through said mixing junction to both said fluid specimen in said first container and to said treating fluid in said second container so that said fluid mixing junction can mix treating fluid with specimen fluid when said pump draws fluid through its first port to its second port to transport a treated specimen fluid into said viewing chamber. - View Dependent Claims (20, 21)
