Abstract
The invention relates to a medical ventilation apparatus (1) having a micro-blower (2) connected fluidically to a gas circuit (3) in order to supply said gas circuit (3) with respiratory gas, a controller (4) controlling the micro-blower (2), an electronic memory (8) configured to store at least several ventilation modes (Modes 1-6), and one or more patient category selectors (6) making it possible to select at least one given patient category from several selectable patient categories (6), and one or more ventilation mode selectors (7) making it possible to select at least one ventilation mode from among several selectable ventilation modes (Modes 1-6) based on the given patient category selected by means of said at least one patient category selector (6).
Core Innovation
The invention relates to a ventilation apparatus comprising a micro-blower connected fluidically to a gas circuit and configured to supply respiratory gas, and a controller configured and adapted to control operation of the micro-blower. An electronic memory stores at least several ventilation modes (Modes 1–6), and a user interface is capable of being actuated by a user to allow selection of a desired ventilation mode and a desired patient category.
The user interface comprises one or more patient category selectors configured to enable selection of the desired patient category from several user selectable patient categories, and one or more ventilation mode selectors from among the several selectable ventilation modes based on the desired patient category. The ventilation mode selectors are configured such that at least one ventilation mode is not selectable in combination with at least one patient category.
The invention addresses preventing incompatible mode/category combinations during user selection on a medical ventilator. The approach uses controller algorithms and stored authorized mode-category combinations to restrict selectable ventilation modes according to the selected patient category, thereby ensuring that only ventilation modes compatible with the selected patient category are available. Selection indicators are provided to show permitted selections and to visually avoid incompatible selections, including embodiments with unlit skipped positions.
Claims Coverage
The claim coverage centers on one independent claim and its dependent features, covering restriction of ventilation mode selector options based on a selected patient category together with controller, memory, and user-interface cooperation.
Restricted ventilation mode selection based on patient category
A user interface having one or more patient category selectors and one or more ventilation mode selectors from among ventilation modes (Modes 1–6) based on a desired patient category, wherein at least one ventilation mode is not selectable in combination with at least one patient category.
Authorized retrieval of ventilation modes per selected patient category
A controller cooperating with an electronic memory to retrieve ventilation modes (Modes 1–6) corresponding to the desired patient category selected via the patient category selectors.
Authorization and/or prohibition of user selection via ventilation mode selectors
A controller cooperating with the ventilation mode selectors to authorize and/or prohibit user selection of ventilation modes (Modes 1–6).
Default adult patient category and stand-by mode
The apparatus is configured to default to an adult patient category and to be in stand-by mode.
Patient category selectors implemented as three selection buttons
The patient category selectors comprise three selection buttons configured to permit selection of the desired patient category chosen from adult, child and infant.
Sequential mode change with validation confirmation
Modifying a ventilation mode during ventilation requires successive actuation by the user of the ventilation mode selectors to move between compatible modes and then actuation of a validation button to confirm the second selected ventilation mode.
Overall, the claim set covers restricting which of Modes 1–6 are selectable based on patient-category selection, implemented via controller logic tied to stored ventilation modes and authorization/prohibition behavior in the ventilation mode selectors, with additional dependent constraints covering default standby behavior, specific patient-category selector UI, and sequential mode-change plus validation confirmation.
