1. A reacting device of dual path synchronous immunochromatographic platform comprising:
a seat having a first slot and a second slot, said first slot being provided for receiving a first immunochromatographic carrier, said second slot being provided for receiving a second immunochromatographic carrier;
an upper housing disposed on said seat, said upper housing including a first window, a second window, a hollow pipe portion, a first end, and a second end; said first window, said second window and said hollow pipe portion being positioned between said first end and said second end, said first window being disposed on said first slot; said second window being disposed on said second slot; said hollow pipe portion being adjacent to said first end and having a top opening, a securing protrusion, an inner space, a first sloped structure, and a second sloped structure; and
a fluid dividing funnel being secured on said securing protrusion through said top opening and extending into said inner space, said fluid dividing funnel having a fluid entrance, a first diversion channel, a second diversion channel, and a force bearing portion; said first diversion channel being disposed on and guided to said first sloped structure, said first diversion channel having a first fluid exit; said second diversion channel being disposed on and guided to said second sloped structure, said second diversion channel having a second fluid exit; said force bearing portion being disposed between said first diversion channel and said second diversion channel;
wherein a specimen is imported into said fluid entrance and said force bearing portion is pressed down so that said first fluid exit and said second fluid exit move towards said first sloped structure and said second sloped structure respectively and said first fluid exit and said second fluid exit being effectuated to deform and slide so as to extend out portionally; said specimen drops from said first fluid exit and said second fluid exit to said first immunochromatographic carrier and said second immunochromatographic carrier respectively; and a reaction result is observable from said first window and said second window respectively;
wherein said fluid dividing funnel is a flexible structure;
and further comprising:
a pressing element for applying a downward force on force bearing portion; said pressing element is a sampler;
wherein said sampler contains a cover and a sampling rod that is extended from said cover so as to allow for applying said downward force toward said force bearing portion;
wherein said top opening is engageable with said cover, said top opening has a connecting portion which is able to be threaded with said top opening and to generate said downward force during a threading process;
a solvent portion disposed on said fluid dividing funnel, said solvent portion including a casing, a lower sealing film, and an upper sealing film; said casing being sealed by said lower sealing film and said upper sealing film and forming a first space for storing a solvent; and
a processing portion disposed on said solvent portion, said processing portion including a lower securing portion, a funnel-like recess portion, and an upper securing portion; said funnel-like recess portion having a through hole for connecting with said upper sealing film, said lower securing portion being provided for said processing portion connecting with said hollow pipe portion;
said sampling rod including at least one annular storing recess and a sting portion;
wherein said annular storing recess is stored said specimen, after said cover engaging with said upper securing portion, said sting portion moving through said through hole and puncturing said upper seal film and said lower seal film, and then apply said downward force on said force bearing portion; when said sting portion moving through said through hole, excess specimen being stayed in said funnel-like recess portion, said specimen stored in said at least one annular storing recess being able to be solved in said solvent and flowing down into said fluid dividing funnel from said first space, said first fluid exit and said second fluid exit pressing said first sloped structure and said second sloped structure respectively.
