Abstract
Lateral flow device pump housings and methods of making such housings are provided.
Claims20
A lateral flow device pump housing comprising:
- a base comprising a cavity for housing a pump, the pump comprising a compressed absorbent pad in contact with an end of a wicking pad;
- and
- a cup nested inside the cavity, wherein a cup side wall is attached to a pump housing side wall in the base and a cup side wall is attached to and directly contacts a pump housing side wall in the cavity, the cup side wall being attached to said pump housing side wall within the cavity by an adhesive, a solvent bond, ultrasonication, laser weld, rivets, or screws;
- or
- wherein the cup side wall comprises a first set of ratchet teeth complementary to a second set of ratchet teeth in the pump housing side wall within the cavity and said sets of ratchet teeth attach the cup side wall to the pump housing sidewall.
2 more elements
A lateral flow device pump housing comprising:
- a base comprising a region for placing a pump, the pump comprising a compressed absorbent pad in contact with an end of a wicking pad;
- and
- a pump cover, wherein the cover is attached to the base with spring loaded hooks.
A method of making a lateral flow device comprising a lateral flow device pump housing, the method comprising:
- providing a pump, a base comprising a cavity for housing the pump, and a cup nested inside the cavity, wherein the pump comprises a compressible absorbent pad in contact with an end of a wicking pad;
- and
- attaching a cup side wall to a pump housing side wall in the base while applying a pressure to the pump with the cup, thereby compressing the pump with the cup.
