FLUID SWITCHING VALVE, FLUID TRANSPORT CARTRIDGE, AND FLUID TRANSPORT DRIVE UNIT
Provided is a fluid switching valve for switching between a plurality of states using a simple configuration. A fluid switching valve is provided with: a first elastic tube through which a first fluid flows; a second elastic tube through which a second fluid flows; a third elastic tube connected at one end to both the first elastic tube and the second elastic tube; and a switching member which, by displacing a protrusion, switches between the following states: a first state in which the first elastic tube is compressed to cause the second fluid to flow to the third elastic tube, a second state in which the second elastic tube is compressed to cause the first fluid to flow to the third elastic tube, a third state in which both the first elastic tube and the second elastic tube are compressed to block the inflow of fluid into the third elastic tube, and a fourth state in which both the first elastic tube and the second elastic tube are not compressed, causing the first fluid and the second fluid to flow to the third elastic tube.

A mechanical switch may be switched off due to a subject into which the present invention is implanted moving around. Once the switch is switched off after the present invention is implanted in the body, it is difficult to turn the switch on again. The present invention is a fluid delivery device which is used by being implanted in the body, the device comprising: a fluid delivery mechanism for discharging a fluid outside from a reservoir that contains the fluid; a transmission reception unit that wirelessly transmits and receives information relating to control of the fluid delivery mechanism to and from an external device; a power supply unit that supplies power to the fluid delivery mechanism and/or the transmission reception unit; and a mechanical switch that is capable only of changing a power supply route from a cutoff state to a conduction state.

There are instances in fluid-conveying devices when it is not possible to accurately discharge a set amount of fluid to be discharged, because of deterioration of an elastic tube over time. Therefore, this fluid-conveying cartridge in a fluid-conveying device, in which mutual separation of the fluid-conveying cartridge and a fluid-conveying drive unit is possible, is provided with: an elastic tube for conveying a fluid; a pressing part that moves between a first position that constricts the conveyance path of the fluid by pressing the elastic tube from the outside, and a second position that does not constrict the path; and a housing part for housing a drive mechanism that moves the pressing part.
There are instances in fluid-conveying devices when it is not possible to accurately discharge a set amount of fluid to be discharged, because of individual differences in the components of the fluid-conveying devices, such as the opening diameter of an elastic tube. Therefore, a fluid-conveying drive unit in a fluid-conveying device, in which mutual separation of a fluid-conveying cartridge and the fluid-conveying drive unit is possible, is provided with: a drive unit for operating a drive mechanism for conveying a fluid, which fills the conveyance path of the mounted fluid-conveying cartridge, to the discharge opening of the conveyance path, and discharging the fluid therefrom; a receiving unit for receiving a property value set for each fluid-conveying cartridge; and a control unit for controlling the drive unit, on the basis of the property value received by the receiving unit.
It is difficult to cover both the communication power required for communication with an external apparatus and the drive power for driving a fluid transport mechanism from one power supply because the required properties are different significantly in a fluid transport device which is used by being buried in the body of a laboratory animal, or the like, in order to administer fluid such as medical solution according to programmed set conditions. The fluid transport device used by being buried in the body is constituted of a fluid transport mechanism for delivering fluid from a reservoir containing the fluid to the outside, a first power supply section for supplying power to the fluid transport mechanism, a receiving section which receives a signal, for changing the set conditions used to control the fluid transport mechanism, from a setting device which is an external device, and a second power supply section for supplying power to the receiving section.
