Abstract
An injection device includes an insertion portion configured to be inserted into a corresponding portion in a narrow space in a state of being grasped by an operator. The insertion portion includes an injection portion which is a double pipe line including an inner pipe line and an outer pipe line defining an annular pipe line between the inner pipe line and the outer pipe line. The inner pipe line is a pipe line provided, at a tip end portion, with a first fluid substance injection port configured to inject a first fluid substance supplied into the inner pipe line. The annular pipe line is a pipe line provided, at a tip end portion, with a second fluid substance injection port configured to inject a second fluid substance supplied into the annular pipe line.

An injection device comprising:
- an insertion portion configured to be inserted into a corresponding portion in a narrow space in a state of being visually grasped by an operator, wherein:
- the insertion portion includes an injection portion which is a double pipe line including an inner pipe line and an outer pipe line defining an annular pipe line between the inner pipe line and the outer pipe line;
- the inner pipe line is a pipe line provided, at a tip end portion, with a first fluid substance injection port configured to inject a first fluid substance supplied into the inner pipe line;
- the annular pipe line is a pipe line provided, at a tip end portion, with a second fluid substance injection port configured to inject a second fluid substance supplied into the annular pipe line;
- and
- the insertion portion further includes an imaging unit configured to capture images including the tip end portion of the inner pipe line, the tip end portion of the annular pipe line, and their surrounding environments.
