  • Publication number: 20220118240
    Abstract: A signal measured by a sensor connected to a needleless connector including a fluid flow path may be obtained to determine, based on the signal, an event associated with the needleless connector, such as at least one of: a scrubbing event in which the needleless connector is scrubbed with a disinfectant, a flushing event in which the needleless connector is flushed with a solution, a connection event in which the needleless connector is connected to a medical device, a disconnection event in which the needleless connector is disconnected from the medical device, or any combination thereof. An indication of the determined event may be provided.

  • Publication number: 20210244932
    Abstract: A sensor assembly may include a sensor surrounding a connector of a medical device. The sensor may be configured to detect a dimension of an end of another connector of another medical device when the another connector of the another medical device is connected to the connector of the medical device. A system may include the sensor assembly and one or more processors programmed and/or configured to determine a type of the another medical device based on the detected dimension. A method may include detecting, with a sensor surrounding a connector of a medical device, a dimension of an end of another connector of another medical device when the another connector of the another medical device is connected to the connector of the medical device; and determining a type of the another medical device based on the detected dimension.
