Title:
SALIVA TREATMENT DEVICES
Document Type and Number:
WIPO Patent Application WO/2021/250672
Kind Code:
A3
Abstract:
An apparatus includes an elongate barrel (162), shaped to define a channel (164) therethrough, in which a porous carrier (170), that holds a surfactant (172), is disposed. A sponge (130) is coupled to the distal portion (124) of a plunger (122) that is dimensioned to slide snugly within the channel. While the sponge holds saliva, sliding of the plunger through the channel compresses the sponge within the channel. Compression of the sponge within the channel drives at least a portion of the saliva: (i) out of the sponge and through the carrier, and (ii) from the carrier, together with at least a portion of the surfactant, into a collection tube (180) that is reversibly couplable to an outlet (168) at a distal region of the channel. Other embodiments are also described.
