Abstract: A medical data processing device according to an embodiment includes processing circuitry. The processing circuitry acquires estimated data related to a state of a biological organ at a first timing, and actually measured data indicating the state of the biological organ at the first timing. The processing circuitry calculates a parameter based on the estimated data and the actually measured data. The processing circuitry estimates a state of the biological organ in a predetermined time phase at a second timing different from the first timing based on the parameter and the estimated data in the predetermined time phase.

Abstract: In order to control the amount of evaporation of discharged agent droplets and so that a user can inhale agent droplets having a constant diameter regardless of use environment, an inhalation apparatus includes an airflow path communicating with a suction port through which the user inhales an agent, an agent discharging portion configured to discharge an agent supplied to the airflow path, and a humidifier located outside the airflow path and configured to humidify an airflow in the airflow path generated by an inhalation of the user.

Abstract: There is provided an inhaler that allows inhalation of droplets having a fixed diameter, regardless of the use condition of the inhaler. The inhaler allows a user to inhale medicine from a suction port thereof. The inhaler includes an air passage through which the medicine passes, the air passage being connected to the suction port, an opening attached to a medicine ejection portion for ejecting the medicine, and provided in a part of the air passage so that the ejected medicine is released into the air passage therethrough, a passage-length determining portion configured to determine the proper distance from the opening to the suction port in accordance with a size of droplets of the medicine ejected from the medicine ejection portion and/or an ejection frequency, and a passage-length changing mechanism configured to change the distance from the opening to the suction port.

Abstract: An inhaler, capable of inhaling liquid droplets having a constant diameter regardless of use environments, for making a user inhale medicine from a suction port has: an air flow path connected with the suction port and for passing the medicine through; an opening mounted with a medicine ejection portion for ejecting the medicine and formed at a part of the air flow path so that the ejected medicine is ejected in the air flow path; a flow path length determining portion for determining a distance from the opening to the suction port according to use environments in using the inhaler; and a flow path length adjustable mechanism capable of changing the distance from the opening to the suction port.
