Publication number: 20230125992Abstract: A microneedle array unit including a microneedle array having a plurality of needle-like protrusions arranged on one surface thereof, a gripping portion provided on a side opposite to the plurality of needle-like protrusions of the microneedle array, and a container configured to accommodate the microneedle array. The container includes an accommodation portion having an opening, a deformable portion disposed on a side opposite to the opening, and a binding portion provided in the accommodation portion of the deformable portion and bound to the gripping portion of the microneedle array. The deformable portion is deformed by receiving an external force in a direction of the opening and presses the microneedle array through the gripping portion, and the microneedle array is pushed out of the accommodation portion by being pressed, and the deformable portion maintains a deformed state and presses the microneedle array.Type: ApplicationFiled: December 27, 2022Publication date: April 27, 2023Applicant: FUJIFILM CorporationInventors: Yuka KOBAYASHI, Yoshiki Sakazaki, Kenichiro Tamaki

Patent number: 11452854Abstract: Provided is a method of manufacturing a microneedle array in which an active ingredient is concentrated at a tip while an active ingredient content is guaranteed. In order to achieve the object, a method of manufacturing a microneedle array in which needle-like recessed portions of a mold are filled with a liquid to form one dose of a patch includes determining a filling amount of the liquid from a difference in mass of the mold before and after filling of the liquid, determining a filling state of the liquid in the mold filled with the liquid, sucking the mold in which the filling amount and the filling state of the liquid are determined to be normal from a rear face, and evaporating and drying a solvent of the liquid of the sucked mold.Type: GrantFiled: April 23, 2019Date of Patent: September 27, 2022Assignee: FUJIFILM CorporationInventors: Yoshiki Sakazaki, Ikuo Takano, Satoshi Wakamatsu, Keio Okano, Kenichiro Tamaki

Patent number: 10999472Abstract: A background image is acquired by imaging an opening plate as a background of an original document in a state where the original document is not arranged. Next, an original document including background image is acquired by imaging the same range as the background image in a state where the original document is arranged on an upper surface of the opening plate. Next, a difference image is generated by subtracting the background image from the original document including background image. In addition, an inverse difference image is generated by subtracting the original document including background image from the background image. A region of the original document is detected based on the difference image and the inverse difference image.Type: GrantFiled: February 14, 2020Date of Patent: May 4, 2021Assignee: FUJIFILM CorporationInventor: Yoshiki Sakazaki
