Physiologically active substance collecting device and biological information acquisition method
A physiologically active substance collecting device, includes: a collecting section brought into contact with a body surface of a living organism to acquire a physiologically active substance from the body surface; and a liquid sending means for sending a solvent to the collecting section, the collecting section having an aperture at which the solvent flown by being sent from the liquid sending means contacts the body surface.
1. A physiologically active substance collecting device, comprising:
a collecting section brought into contact with a body surface of a living organism to acquire a physiologically active substance from the body surface;
one or more channels for sending a solvent to the collecting section, the collecting section having an aperture wherein the solvent flows through the one or more channels to contact the body surface;
an air sending unit that sends air to the collecting section to selectively introduce the solvent and air into the collecting section
a lead-out section that drains the solvent that has contacted the body surface at the aperture;
an absorber that is sent to the lead-out section to absorb and hold the solvent, wherein the absorber that absorbs and holds the solvent is sent to the lead-out section by rotating a core and reeling out the absorber wound around the core; and
a drying unit for evaporating and removing the solvent from the absorber absorbing and holding the solvent.
2. The physiologically active substance collecting device according to claim 1 ,
wherein the collecting section includes a collection substrate that includes a first channel that provides a flow path for the solvent, a solvent inlet for the first channel, a solvent outlet for the first channel, and the aperture positioned between the inlet and the outlet of the first channel.
3. The physiologically active substance collecting device according to claim 2 , wherein the collection substrate is replaceable from the collecting section.
4. The physiologically active substance collecting device according to claim 2 , wherein the collecting section includes an anchor substrate that includes a second channel that provides a flow path for the solvent sent from a solvent tank and a third channel that provides a flow path for the solvent sent to a lead-out section that drains the solvent that has contacted the body surface.
5. The physiologically active substance collecting device according to claim 4 , wherein the anchor substrate is anchored to the collecting section.
