Abstract
An automatic administration instrument includes a syringe and a partition wall in the syringe which partitions the syringe into different rooms for respectively holding plural kinds of drug solutions or a drug and a drug solution. A partition-wall driver displaces the partition wall and an injection needle is connected to the syringe. A body cap attached to the administration instrument body so as to cover the injection needle. The syringe, the partition wall, and the body cap are configured such that displacing the partition wall dissolves or mixes the drug solutions or the drug and the drug solution in a state that the injection needle is covered by the body cap.
Claims2
An automatic administration instrument for medical use for injecting a drug solution filled in a syringe, the automatic administration instrument comprising:
- a body for housing the syringe and an injection needle;
- a first motor for sliding the syringe within the body in a direction toward the tip of the injection needle such that the injection needle protrudes from the body;
- a second motor for operating the syringe to administer the drug solution;
- a switch provided on the body, activating the first motor and the second motor in sequential order while a part of the exterior of the body is pressed against a body region of a patient to which the drug solution is to be administered;
- and
- a current detecting unit for detecting a current flowing in the second motor,
- wherein the switch is configured to activate the first motor such that the injection needle protrudes from the body to perform the injection needle insertion into the body region of the patient, and thereafter activate the second motor to administer the drug solution, and
- wherein the automatic administration instrument is configured that when the current detecting unit detects a current value larger than a reference value, the administration of the drug solution is stopped.
