Medical automatic medicator
First Claim
1. An automatic administration instrument for medical use for injecting a drug solution filled in a syringe, wherein a switching means provided on the body of the administration instrument is operated by pressing a part of the exterior of the body against a body region of a patient to which the drug solution is to be administered, thereby operating a first driving means so that an injection needle housed in the body protrudes from the body to perform needle insertion into the body region, and thereafter, a second driving means for driving the syringe is operated to administer the drug solution.

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.
