  • Publication number: 20250235643
    Abstract: A system for measuring appropriate ventilatory parameters during training that includes one or more sensors, a memory unit that stores the sensor data, a processing unit that computes the data collected to provide real-time feedback on performance. The sensors may measure temperature, volume of airflow, ventilatory rate, ventilatory pressure, and other relevant properties. The stored data includes historical measurements collected over a period of time by the sensors. The processing unit computes the stored sensor data into performance metrics, compares the metrics against objective measures, and determines what real-time feedback to provide to the user so that the user can improve their skills. This feedback may be provided to the user through a multitude of auditory and visual methods. The system may include a range of standard input and output fittings so that it can be used with any common ventilatory or other airway devices during practice.

  • Patent number: 10900023
    Abstract: Disclosed herein are various bioreactor devices and systems for growing cellular material, and related methods of growing cellular material. In some cases, a system can include a well plate having a plurality of wells and a bioreactor situated in each well of the well plate. In some cases, a bioreactor can include an inner body which divides the bioreactor into several distinct chambers and facilitates the growth of a multi-tissue sample in the bioreactor. In some cases, a system can include a mechanical actuator situated to mechanically stress tissues grown in a bioreactor.

  • Patent number: 10325522
    Abstract: A medical training method includes generating an image of a first level of anatomical structures, displaying the image in a correct registration in a first display area on the surface of a portion of a simulated body, detecting a user input associated with the portion of the simulated body, and responsive to said detecting, generating and displaying at least one visual image in a correct registration in the first display area. A system for carrying out such method is also provided.

  • Patent number: 10060936
    Abstract: A system for identifying a drug simulant includes an electronic sensing system structured to measure the value of an inherent property of the drug simulant; a processing unit in electrical communication with the electronic sensing system; and a memory unit in communication with the processing unit, the memory unit having a look-up table including a range of values of the inherent property of a given fluid and corresponding names of simulated drugs associated with each value. The processor is structured to identify a name of the simulated drug corresponding to the drug simulant by receiving signals indicative of the value of the measured inherent property from the sensing system and comparing the value to the look-up table in the memory.
