1. In a body fluid collection reservoir, an improvement comprising:
- a tablet in the reservoir, which tablet upon encountering the body fluid dissolves to produce hydrogen peroxide, which tablet is partially coated with a nondissolving coating leaving a fixed surface area uncoated and exposed to the body fluid, which fixed surface area remains substantially constant as the tablet dissolves in the body fluid.

Abstract
An assembly for inhibiting microbial growth in collected body fluid includes a reservoir for collecting the fluid, and a tablet in the reservoir, which tablet dissolves in the collected fluid to produce hydrogen peroxide in an amount sufficient to inhibit microbial growth in the collected fluid. The tablet is partially coated with an insoluble coating which leaves a portion of the tablet uncoated to provide a constant surface area exposed to the collected body fluid, which surface area is of a size to provide sufficient hydrogen peroxide for inhibition of microbial growth.

17. A urinary drainage and collection assembly for collecting urine drained from a patient and for inhibiting microbial growth in the collected urine, the assembly comprising:
-
a urinary catheter for implanting in a patient'"'"'s urinary tract for draining urine from the patient; a collection reservoir in fluid communication with the catheter for collecting urine drained from the patient; and a tablet in the reservoir, which tablet dissolves in urine to produce hydrogen peroxide and which tablet is partially coated with a urine insoluble coating, leaving a sufficient surface area uncoated on the tablet, which surface area remains substantially constant as the tablet dissolves in the collected urine to provide a uniform release of hydrogen peroxide in an amount sufficient for inhibiting microbial growth in the collected urine. - View Dependent Claims (18, 19, 20)

21. A method for inhibiting the growth of microbes in a collected body fluid, the method comprising the step of:
introducing to a reservoir for collection of body fluid a tablet which is capable of dissolving in such body fluid and releasing hydrogen peroxide, the tablet being partially coated with an insoluble coating leaving uncoated a surface area of the tablet, which surface area remains substantially constant as the tablet dissolves and which is sufficient for releasing sufficient hydrogen peroxide for inhibiting microbial growth in the collected body fluid. - View Dependent Claims (22, 23, 24, 25)
