Description

The present invention relates to an infusion device for injecting a drug solution or the like.

Syringe pumps and infusion pumps are known as infusion devices for injecting a predetermined amount of a drug solution or the like into a patient. Since the chemicals used in such an infusion device include powerful drugs that are required to be injected with high accuracy, if a problem occurs due to misuse or misoperation, the effect on the patient is great. Therefore, the infusion device is provided with a safety mechanism such as a key lock so that an operator other than the intended operator cannot stop the injection or change the flow rate without permission (see, for example, Patent Document 1).
Currently, the key lock installed in the infusion device functions by selecting from an item such as a menu or pressing and holding a specific button, and unless an operation equivalent to unlocking the key is performed. All operations are disabled except for operations such as turning off the power to improve safety.
