Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a used syringe needle heating process for heating a used syringe needle to a sterilization temperature in an odorless state when heating the used syringe needle in a sterilization heating device such as an autoclave. Concerning vessels.

(Prior art) In the past, injection needles used in hospitals, etc. are sterilized in an autoclave or other sterilization heating device to prevent blood-borne diseases such as hepatitis and AIDS, and then disposed of through a designated disposal route. Will be discarded. When sterilizing used needles by the above method, place the used needles in a designated needle storage can,
The injection needle housing opening is sealed with sticker paper, and then heated in an autoclave or the like for the required time.

(Problems to be Solved by the Invention) In the case of the conventional used syringe needle heat treatment means described above, when the syringe needle storage can containing the used syringe needles is set in an autoclave and heated, blood adhering to the used syringe needles etc. evaporates during the heating process and presses the sticker paper from inside, causing a fairly strong odor to leak from the sticker paper, making it difficult to heat treatment in a medical room where doctors, patients, or nurses are present. There was a problem in that heat treatment had to be performed outdoors, and sterilization was time-consuming.

Therefore, in the present invention, when heating the syringe needle storage can containing used syringe needles with a sterilization heating device such as an autoclave,
The technical problem to be solved is to make it possible to perform heat treatment near the place where the injection needle is used, such as in a medical room, by containing the bad odor leaking from the sticker paper, and to easily and reliably perform sterilization. It is something.

(Means for solving the problem) The technical means for solving the above problem is to seal the needle storage can with the needle storage opening sealed after putting the used needle in, and then heat it with a sterilization heating device. , the used syringe needle heat treatment device for sterilizing the used syringe needles includes a main body formed of a corrosion-resistant metal and accommodating the syringe needle storage can through a circular opening having a threaded portion formed on the curved surface; an outer cover having a threaded portion formed on its circumferential surface to be screwed into the threaded portion of the circular opening of the main body, and a threaded portion also formed on the circumferential surface of a hole bored in the center; an inner lid that covers the needle accommodating port forming surface of the syringe needle storage can; and an inner lid that covers the syringe needle accommodating port forming surface of the syringe needle storage can housed in the main body; The formed threaded part is screwed into the threaded part of the circular opening of the main body, and with the outer cover closed to a predetermined position, the hole opened in the center of the outer cover is closed. For pressing the syringe needle accommodating opening forming surface of the syringe needle accommodating can with a predetermined pressure by screwing into the threaded portion and rotating the syringe, the tip portion of the syringe needle accommodating can is pressed against the syringe needle accommodating port forming surface of the syringe needle accommodating can by screwing forward and bringing the distal end portion into contact with the end surface of the inner lid. The present invention is to provide a configuration including a suppressing threaded rod.

(Function) According to the used syringe needle heat treatment device having the above configuration, after putting the used syringe needle into the syringe needle storage can with the syringe needle storage opening sealed, the syringe can be injected into the syringe needle storage can. Place the inner cover over the surface where the needle accommodating opening is formed, then engage the threaded part of the outer cover with the threaded part of the circular opening of the main body, rotate it, and close it to the specified position. When screwed into the threaded part of the hole drilled in the center of the syringe and rotated until it stops rotating, the tip of the press screw rod presses the inner lid and forms the syringe needle storage opening of the syringe needle storage can. Press the surface with the required pressure. When it is set in a sterilization heating device in this state and heated for a required period of time, the heat conducted through the main body and the needle storage can heats and sterilizes the used needle contained in the needle storage can.

When the blood etc. adhering to the used syringe needle is heated in the above heating process, it vaporizes and presses the sealing material sealed on the surface of the syringe needle accommodating opening of the syringe needle storage can from inside. Since the pressed inner lid, including the sealing material, presses the surface where the injection needle storage opening is formed, the bad odor emitted when blood etc. attached to the used injection needle is heated can be contained in the injection needle storage can.

Furthermore, an airtight member is provided to maintain an airtight state between the peripheral edge of the circular opening formed in the main body and the peripheral edge of the inner lid, and an airtight member is provided to maintain an airtight state between the peripheral edge of the circular opening formed in the main body and the peripheral edge of the inner lid. Even if some bad odor leaks from the sealing material, it can be prevented from leaking out of the used syringe needle heat treatment device by the airtight maintenance member for holding the used syringe needle in place.
