Abstract: Systems and methods for model-driven system integration on a ventilator comprise a modeled exhalation flow. Ventilator flow sensors contain components that are easily damaged or impacted and have high rates of failure. Knowledge failure frequency and type may help determine when to replace, clean, or calibrate a flow sensor. A modeled exhalation flow may be trained for a ventilator. Additionally, the modeled exhalation flow may be compared to a flow sensor flow to determine a specific failure. Additionally or alternatively, the modeled exhalation flow may supplement, weight, or replace a faulty flow sensor measurement. These systems and methods may assist in identifying an inaccurate flow sensor measurement and/or providing a more accurate modeled flow estimate, thus increasing accuracy in patient-ventilator interactions.

Abstract: A massage gun includes a gun body, a massage head arranged on the gun body, an auxiliary physiotherapy assembly arranged in the massage head, a main circuit board arranged in the gun body, and a connecting cable electrically connected to the auxiliary physiotherapy assembly and the main circuit board, where the connecting cable is made of a conductive wire resistant to high-speed bending. The connecting cable electrically connected to the auxiliary physiotherapy assembly in the massage head is made of the conductive wire resistant to high-speed bending, which solves the problem that the connecting cable breaks easily when the massage gun performs high-speed piston movement. Because the connecting cable does not break easily, electrical connection can be maintained, thereby prolonging the service life of the massage gun, and reducing use costs.
