Fluid transportation device
First Claim
1. A fluid transportation device comprising:
- an outer case constituted from an upper cover and a lower cover, having a sealed space;
a tube having elasticity;
a fluid transport mechanism, having a plurality of fingers that occlude the tube and a cam that successively presses the plurality of fingers from an inlet portion to an outlet portion, making a fluid flow continuously by squeezing the tube;
a driving force transmission mechanism disposed so as to be overlapped with the fluid transport mechanism, transmitting a driving force to the fluid transport mechanism;
a reservoir disposed at a position at which it does not overlap with the fluid transport mechanism and the driving force transmission mechanism, being in communication with the inlet portion of the tube, and containing the fluid;
a port injecting the fluid into the reservoir; and
an electric power supply supplying electric power to the driving force transmission mechanism, wherein at least the fluid transport mechanism, the driving force transmission mechanism, and the electric power supply are housed in the sealed space of the outer case.

Abstract
A fluid transportation device includes: an outer case having a sealed space; a tube having elasticity; a fluid transport mechanism having fingers that occlude the tube and a cam that successively presses the plurality of fingers; a driving force transmission mechanism disposed so as to be overlapped with the fluid transport mechanism, and transmitting a driving force to the fluid transport mechanism; a reservoir disposed at a position so as not to overlap the fluid transport mechanism and the driving force transmission mechanism; a port through which the fluid is injected into the reservoir; and an electric power supply supplying electric power to the driving force transmission mechanism. In this fluid transportation device, at least the fluid transport mechanism, the driving force transmission mechanism, and the electric power supply are housed in the sealed space of the outer case.

10. A fluid transportation device used for implantation under skin, the fluid transportation device comprising:
-
an outer case having a skin side surface and a rear surface, the skin side surface facing the skin when the fluid transportation device is implanted under the skin;
a port disposed at the skin side surface, having an injection opening which is exposed to the exterior of the outer case and enables injection of a fluid from the exterior;
a reservoir storing the fluid injected from the port;
a fluid conducting portion communicated with the reservoir, to allow the fluid to be conducted;
a micropump feeding the fluid to the exterior via the fluid conducting portion; and
a battery supplying power to the micropump. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
