A hemofiltration device capable of surely performing highly-efficient hemofiltration. The hemofiltration device of the present invention is adapted to be implanted in a mammalian body for filtering blood, and includes a blood flow path layer having a blood flow path, a filtrate flow path layer having a filtrate flow path disposed along the blood flow path, and a filtration membrane interposed between the blood flow path layer and the filtrate flow path layer, for filtering the blood flowing through the blood flow path. A filtrate outlet of the filtrate flow path is provided at a position closer to a blood outlet than to a blood inlet of the blood flow path. The blood inlet, blood outlet, and filtrate outlet are provided only on one side or separately on opposite sides of a main body portion in the direction in which the layers are stacked.

A taste substance-supplying article is provided with: a taste substance-supplying body having a taste substance that is brought into contact with taste receptors to produce a sense of taste, and a taste-releasing part that retains the taste substance and gradually releases the taste substance; and a fixing part that fixes the taste substance-supplying body to an oral cavity so that the taste-releasing part can be brought into contact with a portion of an area being a part of the oral cavity and having taste receptors. The taste-releasing part is brought into contact with taste receptors, and supplies and causes the taste substance to come into contact with the taste receptors.

Taste substance-supplying article

A pump unit which can be made to be small-sized, and which enables to achieve a sufficient flow and an endoscope apparatus using such pump are provided. The pump unit which transports a fluid in a channel upon generating a progressive wave which is propagated in a longitudinal direction of the channel, in a first flexible thin film which constitutes at least a part of a channel-wall surface, includes a vibration exciter unit.
