Administration instrument for medical use
First Claim
1. An administration instrument for medical use, comprising:
- a needle contact detection unit configured to detect that a needle is touching skin;
an injection completion detection unit configured to detect that injection has been completed;
an injection amount detection unit configured to detect an amount of the injection administered;
an injection amount recording unit configured to record the amount of the injection administered; and
a control unit configured to control the injection amount detection unit and the injection amount recording unit to record the amount of the injection administered only when the injection completion detection unit detects that the injection has been completed and the needle contact detection unit detects that the needle is touching the skin, after an air removal operation has occurred in a state in which the needle contact detection unit does not detect that the needle is touching the skin and the injection amount recording unit does not record the amount of the injection administered.

Abstract
An administration instrument for medical use that can perform injection of a drug solution with stability and with great reliability. For example, at administration, it is possible to prevent a force that presses the injection button from acting in a direction of inserting the needle that is inserted into the skin deeper, and enables the administration under a stable state where the needle does not wobble, thereby alleviating physical and mental pain of the administration patient. With a structure in which an injection button is pressed at an angle that is not parallel to the needle with respect to a direction in which the needle is inserted into the skin, it is possible to prevent the force of pressing the injection button from being transmitted in a direction of inserting the needle into the skin deeper than the initial insertion of the needle, thereby achieving an administration under a stable state.
