Dragerwerk has filed a patent for a medical system that provides setting recommendations for ventilators. The system uses static and dynamic patient data to determine a new current patient data set and compares it to stored assignment rules to recommend device settings. The recommendation is then outputted through a display. GlobalData’s report on Dragerwerk gives a 360-degree view of the company including its patenting strategy. Buy the report here.

A medical system for recommending ventilator settings based on patient data

A recently filed patent (Publication Number: US20230317265A1) describes a medical system designed to provide recommendations for ventilator settings for patients. The system includes a data interface to receive static patient data, which consists of patient parameters that remain relatively constant throughout the treatment period. It also has a measurement interface to receive dynamic patient data, which includes patient parameters that change over the course of treatment.

The system utilizes a rule memory unit that stores a variety of assignment rules. Each assignment rule links a range of values for a patient parameter to a recommended setting for a ventilation parameter of the ventilator. A processing unit analyzes the static and dynamic patient data to determine a new current patient data set. This data set is then compared to the stored assignment rules, and based on this comparison, the system receives a recommended device setting for the ventilator.

The system also compares the recommended device setting to the current device setting of the ventilator and triggers a recommendation output based on the comparison. This recommendation output indicates the recommended setting for the ventilation parameter based on the recommended device setting. An output unit receives the recommendation output and graphically displays the corresponding setting recommendation on a display.

The patent also describes additional features of the medical system. For example, the comparison between the recommended device setting and the current device setting only triggers a recommendation output if the recommended setting value and the currently present setting value have a predetermined minimum difference. The recommendation output can also indicate the assignment rule referenced for the recommended device setting, and the output unit can graphically display the referenced assignment rule.

The processing unit can output multiple recommended device settings, along with the corresponding assignment rules, if the recommended setting values and the currently present setting values have the predetermined minimum difference. The system can also consider static patient data before dynamic patient data when determining the current patient data set, based on a predetermined processing hierarchy.

Overall, this patent describes a medical system that uses patient data and assignment rules to provide recommendations for ventilator settings. The system aims to improve the efficiency and accuracy of ventilator management for patients.
