Diagnostic testing device
First Claim
1. A diagnostic testing device comprising, in combination,a base member defining a cavity, a plurality of antibiotic units within said cavity;
- a cover member on said base member, said cover member defining a central cover opening for the reception of a liquid specimen;
a central member positioned between said base member and said cover member, said central member having said plurality of antibiotic units spaced inwardly from its periphery;
distribution means comprising a porous wicking material positioned between said cover opening and said antibiotic units for delivering portions of the liquid specimen to said antibiotic units, said distribution means including a fibrous distribution wheel having a central portion and a plurality of legs extending outwardly from said central portion, said fibrous distribution wheel being positioned on said central member, the outer ends of each of said legs received by a respective one of said antibiotic units;
indicator means in communication with said cover member for indicating the effectiveness of antibiotics;
delivery means comprising a porous wicking material extending upwardly from each of said antibiotic units, whereby relative vertical movement between said delivery means and said indicator means places said delivery means and said indicator means into an engaging relationship, said delivery means including a fibrous cylinder positioned in each of said antibiotic units and extending upwardly toward said cover member; and
means for stably biasing said cover member and said central member in first and second positions relative to each other whereby in said first position said fluid delivery means and indicator means are not in fluid communication with each other and in said second position said fluid delivery means and indicator means are in fluid communication with each other.

Abstract
A diagnostic testing device is disclosed. The testing device includes a base member and a cover member which defines an opening for the reception of a liquid specimen. A distribution wheel delivers portions of the specimen to antibiotic units which are circumferentially spaced. Indicator units are in communication with the cover member. A delivery cylinder extends upwardly from each of the antibiotic units toward a respective one of the indicator units. Relative vertical movement between the delivery cylinder and the indicator unit places the cylinder and the indicator unit into an engaging relationship. A change in coloration at an indicator unit indicates a positive reaction.

15. A diagnostic testing device comprising, in combination,
a base member defining a cavity, a central member positioned in said cavity, a plurality of antibiotic units spaced inwardly from the periphery of said center member, each of said antibiotic units including a generally cylindrical member extending upwardly from said central member, said cylindrical member receiving an antibiotic disk; -
a cover member on said base member, said cover member defining a central cover opening for the reception of a liquid specimen; distribution means comprising a porous wicking material positioned between said cover opening and said antibiotic units, said distribution means including a liquid supply conduit extending downwardly from said cover opening and a fibrous distribution member having a central portion in liquid communication with said supply conduit and a plurality of liquid transmission legs extending outwardly from said central portion to said antibiotic units, said fibrous distribution member being positioned on said central member, the outer ends of each of said legs being received by a respective one of said cylindrical members, an antiobiotic disk engaging said cylindrical member adjacent such outer end of said leg; indicator means in communication with said cover for indicating the effectiveness of antibiotics, wherein said indicator means includes a plurality of indicator stations defined by said cover member; delivery means including a fibrous cylinder of a porous wicking material positioned in each of said cylindrical members and extending upwardly from each of said antibiotic units toward said cover member, whereby relative vertical movement between said delivery means and said indicator means places said delivery means and said indicator means into an engaging relationship and; means for stably biasing said cover member and said central member in first and second positions relative to each other whereby in said first position said fluid delivery means and indicator means are not in fluid communication with each other and in said second position said fluid delivery means and indicator means are in fluid communication with each other. - View Dependent Claims (16, 17, 18)
