Patent number: 11732965Abstract: A freeze-drying device includes a controller configured to control depressurization of containers filled with a liquid including a raw material and a medium to freeze the liquid from a liquid surface. The freeze-drying device also includes a gas capture pump configured to exhaust a freeze-drying chamber accommodating the containers, and a positive-displacement pump configured to discharge gas from a space accommodating the gas capture pump. The controller executes an exhaust mitigation process that performs the depressurization at an exhaust capability that is less than a rated exhaust capability of the freeze-drying device. The controller uses a partial pressure value of the medium to determine when the exhaust mitigation process ends. The controller maintains an exhaust speed of the gas capture pump and decreases an exhaust speed of the positive-displacement pump in the exhaust mitigation process.Type: GrantFiled: September 27, 2022Date of Patent: August 22, 2023Assignee: ULVAC, INC.Inventors: Tsuyoshi Yoshimoto, Yoichi Ohinata, Tomomitsu Ozeki

Publication number: 20110269149Abstract: It is an object of the invention to provide a method for rapid and accurate quantification of a sample in the human body of a patient. The invention relates to a method for quantification of the body internal concentration of a protein-based drug, comprising step A comprising using a sensing device mounted with a substance binding to a protein contained in the protein-based drug through a specific interaction to determine the binding mass per unit area of a solution containing the protein-based drug to the substance mounted on the sensing device as a standard value and step B comprising assaying a collected biological sample by the sensing device and comparing the resulting value with the standard value to determine the concentration of the protein-based drug contained in the biological sample. In such a manner, the blood concentration of a circulating protein-based drug can be quantified in patient bodies, to determine the optimal dose and enable an effective therapeutic treatment.Type: ApplicationFiled: January 15, 2010Publication date: November 3, 2011Inventors: Tomomitsu Ozeki, Tomofumi Jitsukawa, Masato Mitsuhashi
