Definitions

  • the invention relates to a connector for a patient ventilation system.

  • this object is achieved according to the invention by a connector having the features specified in claim 1.
  • a signal data memory can be used as part of the connector to store signal data for their later internal and / or external signal data processing.
  • the signal data memory can then, in the manner of a buffer, initially collect the signal data generated in particular by the at least one sensor of the connector in order to feed them for later processing.
  • a log file can be written in the signal data memory, which can be used to log the duration of the connector's service life.
  • the recorded signal data but also other information, such as B. acquisition times and other data, e.g. B. identification data on connector components and / or the sensors used and / or the data standards used can be stored.
  • the signal data memory can also be used for other data, for example to store a type designation of the connector and / or the patient ventilation system equipped with it, as well as other components, an operating manual for the connector and / or other components of the ventilation system, and safety instructions in relation to the connector and / or other components of the ventilation system.
  • the signal data memory can have its own interface for reading via an external component, for example via RFID or via NFC (Near Field Communication).
  • the breathing air hose section that is connected to the connector can be a heatable breathing air hose section.
  • the hose section can also be lead out of non-heatable manner.
  • a processing module enables internal signal data processing in the connector.
  • Examples of data processing that can take place in the processing module are data filtering, data volume reduction, feature extraction and feature selection, a classification of the data in a given classification scheme, a sensor data fusion and a sensor data standardization.
  • machine-running algorithms e.g. B. Tit-in, and / or decision trees / decision networks are used that are known in connection with neural networks and artificial intelligence (AI).
  • the processing module is in signal connection with the signal data memory.
  • the processing can be used to identify the status of the ventilation system and / or a patient connected to it. Corresponding status information and possibly warning signals can then be passed on to a display unit of the connector and / or to an external component.
  • Measures can be taken to respond to a corresponding status detection.
  • captured environmental parameters such as. B. temperature and air humidity
  • functions of the breathing system can be controlled or regulated, or an exchange of components of the breathing system can be prepared. Big data applications are possible by processing and / or forwarding the data that is saved with the signal data memory.
  • An identification data record stored in the memory according to claim 3 permits an unambiguous assignment, in particular at least one disposable component of the connector. Such a data record can be used to protect against plagiarism.
  • a plurality of sensors according to claim 4 increases the possible uses of the connector.
  • the processing module if it is provided for processing the recorded sensor data, can combine the raw signal data of several sensors recorded by the sensors with one another for processing. This can improve the quality, in particular, of a status recognition of the ventilation system and / or of a patient connected to it.
  • this can, for example, compress acquired sensor data and / or bring it into a further processable data format.
  • the processing module can be used to select recorded raw sensor data. This makes it possible, for example, to pass on maximum or minimum sensor values that are recorded by the sensor within a certain period of time.
  • a sensor according to claim 6, which measures at least one breathing air parameter in contact with the breathing air can be used for a precise measurement of the breathing air parameter.
  • the sensor can be designed in such a way that it measures more than one breathing air parameter.
  • the sensor can be a gas composition analysis sensor, a flow sensor and / or a humidity sensor.
  • At least one environment sensor helps to significantly improve the quality of a condition detection, in particular a patient condition, but also the ventilation system.
  • a condition detection in particular a patient condition, but also the ventilation system.
  • Such an ambient sensor can be a sensor for detecting an ambient brightness and / or a microphone.
  • a stress level for the patient can be assessed based on what can be responded to by appropriate control / regulation of the ventilation system.
  • a motion detection sensor helps, in particular, to allow additional patient movements to flow into a state detection. It is also possible to record a movement pattern, for example using a Fourier analysis of the data output by the movement detection sensor. This can also be used to draw conclusions about a patient's condition.
  • An acceleration sensor can be used as a motion detection sensor.
  • An analysis sensor makes it possible to readjust a breathing air source of the ventilation system accordingly.
  • the analysis sensor is arranged in the ventilation system, for example, in the area of a guide of exhaled breathing air, the patient's condition z. B. close via a measured CCE value of the exhaled breath.
  • a breathing gas pressure sensor enables breathing pattern recognition and a conclusion about the patient's condition.
  • An interface connection with an external sensor according to claim 11 enables additional external sensor data to flow into the signal data processing, for example the data of a heart rate measurement, a body temperature measurement and / or a measurement of a main surface resistance of the patient.
  • a contactless sensor measurement according to claim 12 enables the breathing air to be routed tightly in the area of the sensor. The requirements placed on the biocompatibility of the sensor are reduced.
  • the Connector can have both a sensor that measures the breathing air parameter in contact with the breathing air, and a sensor that measures the breathing air parameter without contact. This can be used to generate an error security in such an air measurement. A redundant measurement can be achieved.
  • a cover layer according to claim 13 can, if the sensor is designed as a temperature sensor, be designed as a heat coupling layer. If the sensor is designed as a pressure sensor, the cover layer can be designed as a pressure coupling layer.
  • a design of the cover layer according to claim 14 as an optical window enables the use of an optical sensor. This can be used to measure an absorption or scattering of the breathing air and / or a measurement of a reflection of an inner wall of a lumen of the connector carrying the breathing air, which in turn draws conclusions about breathing air parameters, the condition of the ventilation system and / or the condition of the patient allows.
  • the optical sensor can be designed as a spatially resolving sensor.
  • a measurement of moving particles, such. B. of flowing condensate or condensation droplets possible.
  • This also enables the status of the ventilation system to be recognized and, for example, allows a warning signal to be output if the flowing condensate threatens to flow into other areas of the ventilation system in an undesired manner.
  • the object mentioned at the beginning is achieved according to a further aspect in accordance with the invention by a connector having the features specified in claim 15.
  • control / regulating unit with several and, in particular, different signal transmission interfaces enables the connector to be flexibly expanded to include additional internal and / or external sensors.
