  • Patent number: 10207100
    Abstract: The present invention is an injection port with an articulated stopcock allowing a syringe to be connected to an IV line and, depending upon the orientation of the stopcock, allow (1) bidirectional flow of fluid through the stopcock into the IV line, (2) no flow or (3) unidirectional flow of fluid through the stopcock and into or out of the IV line. The invention is particularly useful for using a syringe for aspirating an IV line and then injecting a medicine from the syringe into the IV line. Once a syringe is connected, the invention allows one-handed manipulation of the articulated stopcock into the three orientations by simply moving the connected syringe into one of the three orientations, thereby eliminating the need for using two hands—one to operate the syringe and the other to operate the handle.

  • Patent number: 9480788
    Abstract: A control module for a medical injection system generates an injection control signal based on sensed internal pressure of a user activated control device, for example, in response to an applied external force that causes the sensed internal pressure to increase from a baseline pressure, and continues to sense the internal pressure of the device, following release of the applied external force, so that, if the sensed internal pressure drops below the baseline pressure, the control module may generate a notification. Thus, an operator of the system may monitor internal pressure of the control device for a drop below the baseline pressure, and then, if such a drop is detected, inspect the control device for leaks and reconnect, replace or repair the control device, or simply reconnect or replace the control device.

  • Publication number: 20010044600
    Abstract: The present invention relates to closed catheter suction systems used to aspirate secretions from the trachea of a patient and to rinse the catheter after such aspiration. The apparatus comprises a flexible suction catheter encased within a sheath that is fixed to a vacuum source at its proximal end and extendable through an adapter assembly at its distal end, near the patient. The adapter assembly connects the closed catheter suction system to a patient connector, and a suction control valve at the proximal end operates to aspirate secretions and to rinse the catheter. The closed catheter suction system also includes a lavage port and a rinse port, the latter of which is positioned near the distal end and is isolated from the ventilation circuit through the innovative use of a rinse chamber and a one-way valve. Advantageously, the lavage port is positioned near the proximal end, away from the patient, so as to prevent the accidental leakage of lavage into the ventilation circuit.
