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.

Abstract: After pressing a part of the exterior of a body of an administration instrument against a body region of a patient to which a drug solution is to be administered, an injection needle that is housed in the instrument body is automatically protruded from the body to insert the needle into the body region, and further, the injection needle being inserted into the body region is automatically housed in the instrument body to remove the needle from the body region. Thereby, the pain of the patient during needle insertion and needle removal is reduced, and administration at a constant speed is possible during injection of the drug solution. Furthermore, even when two kinds of drug solutions or a dissolving and mixing type drug solution are/is used, mixing can be easily and reliably carried out.

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.
