Patent ID: 8778276

Claim:
A device for detecting multiple target analytes on a surface comprising: (a) a female member having a first region situated at an upper opening end of the female member and a second base region situated at a base of the female member, the second base region comprising (i) an orifice and (ii) an absorbent material supported within the second base region which is externally available through the orifice and that can absorb the target analyte, (b) a plunger engaged within the first region of the female member which is capable of movement within the female member in response to an applied force, the plunger comprising (i) multiple detection means to detect the multiple target analytes and (ii) a head comprising multiple orifices; and (c) a removable cap for sealing the orifice in the second base region of the female member, wherein in use, the orifice in the second base region contacts a surface to absorb fluid containing the multiple target analytes, the removable cap is attached to seal the orifice in the second base region to prevent the fluid from being dispelled from the device, and external force is applied to the plunger which applies pressure to the absorbent material to cause fluid containing the multiple target analytes absorbed to the absorbent material to be forced through the multiple orifices in the plunger head and to contact the multiple detection means.
