Abstract

A fluid injection system includes: a first apparatus which is attached to a human body and injects a fluid into the human body; and a second apparatus which is attached to a wrist of the human body and remotely controls the first apparatus, wherein the second apparatus includes an entry section accepting an entry of an operation command to the first apparatus and a first communicating section transmitting the operation command to the first apparatus, and the first apparatus includes a second communicating section receiving the operation command, a storing section storing the fluid, and a transporting section transporting the fluid from the storing section and injecting the fluid into the human body based on the operation command.

Claims

1. A fluid injection system, comprising:

a first apparatus which is attached to a human body and injects a fluid into the human body; and

a second apparatus which is attached to a wrist of the human body and remotely controls the first apparatus, wherein

the second apparatus includes

an entry section accepting an entry of an operation command to the first apparatus, and

a first communicating section transmitting the operation command to the first apparatus, and

the first apparatus includes

a second communicating section receiving the operation command,

a storing section storing the fluid, and

a transporting section transporting the fluid from the storing section and injecting the fluid into the human body based on the operation command.

2. The fluid injection system according to claim 1, wherein

the second apparatus includes

a first detecting section detecting living body information of the human body, and

a first calculating section calculating, based on the living body information, a fluid flow rate of the fluid which is injected by the first apparatus,

the first communicating section transmits data on the fluid flow rate calculated by the first calculating section to the first apparatus,

the second communicating section receives the data on the fluid flow rate calculated by the first calculating section, and

the transporting section transports the fluid from the storing section and injects the fluid into the human body based on the data on the fluid flow rate calculated by the first calculating section.

3. The fluid injection system according to claim 1, wherein

the second apparatus includes

a second detecting section detecting an acceleration of the second apparatus, and

a second calculating section calculating a fluid flow rate based on the acceleration,

the first communicating section transmits data on the fluid flow rate calculated by the second calculating section to the second apparatus,

the second communicating section receives the data on the fluid flow rate calculated by the second calculating section, and

the transporting section transports the fluid from the storing section and injects the fluid into the human body based on the data on the fluid flow rate calculated by the second calculating section.

4. The fluid injection system according to claim 1, wherein

the first apparatus includes

a controller controlling the transporting section, and

a second monitoring section monitoring the controller, and

the second apparatus includes

a first monitoring section monitoring the controller, and

an alerting section issuing an alert when the first monitoring section or the second monitoring section detects an abnormality in the controller.

5. The fluid injection system according to claim 1, wherein

the first apparatus includes a measuring section measuring a fluid flow rate of the fluid transported by the transporting section, and

the second apparatus includes

a first determining section determining whether or not something is wrong with the transporting section based on the operation command and data on the fluid flow rate, and

an alarm section sending an alarm when the first determining section determines that something is wrong with the transporting section.

6. The fluid injection system according to claim 5, wherein

the second apparatus includes

a third calculating section calculating a remaining amount of the fluid in the storing section based on the transportation amount of fluid measured by the measuring section and the amount of fluid originally stored in the storing section, and

a display section displaying the remaining amount calculated by the third calculating section.

7. The fluid injection system according to claim 1, wherein

the fluid is a chemical which reduces a blood sugar level of the human body,

the first apparatus includes a third detecting section detecting the blood sugar level of the human body, and

the second apparatus includes a second determining section which determines that the human body is in a state of hypoglycemia when the blood sugar level is less than a predetermined value and transmits an operation command to stop injection of the fluid to the first apparatus via the first communicating section.

8. The fluid injection system according to claim 7, wherein

the second determining section determines that the human body is in a state of hyperglycemia when the blood sugar level becomes equal to or more than a predetermined value and transmits an operation command to increase an injection dose of the fluid to the first apparatus via the first communicating section.
