Means For Indicating Improper Condition Of Apparatus Patents (Class 128/202.22)
  • Patent number: 11173262
    Abstract: The disclosure provides a way to supplement the tidal volume delivered to the patient by a leaking re-breather when the delivered volume becomes less than that set by the ventilator (in either pressure-regulated or volume modes). This may be accomplished with a shunt—a gas conduit joining the non-patient side of the re-breather to the patient side. A low-resistance, plenum or a draw-over vaporizer may also be incorporated into the gas pathway. Such a device may include a housing with a movable partition separating an actuating side from a patient side. The housing includes a ventilator orifice for pneumatic communication between a ventilator and the actuating side and a patient orifice for pneumatic communication between the patient side and a patient. A shunt defines a bypass flow path from the actuating side and to the patient side when the moveable partition is at a maximal displacement towards the patient side.

  • Patent number: 10765822
    Abstract: Systems and methods for detecting extubation of an endotracheal tube (ETT) are described. Extubation of the ETT can be identified by comparing to a threshold, a difference between a determined first volume of breathing gas during a first inspiratory period to a determined second volume of breathing gas during a second inspiratory period. If the difference exceeds the threshold, an alarm can be activated indicating extubation. Extubation detection may also be based on a difference between inspiratory pressures during separate inspiratory periods. Partial extubation and full extubation may also be discerned. Further, extubation of an ETT may be detected without the use of an exhalation flow sensor.

  • Patent number: 10105509
    Abstract: An active exhalation valve for use with a ventilator to control flow of patient exhaled gases. The valve includes a patient circuit connection port, a patient connection port, an exhaled gas port, a pilot pressure port, and a valve seat. The valve further has a movable poppet with inner and outer bellows members and a bellows poppet face. An activation pressure applied to the pilot pressure port extends the bellows members to move the poppet face into engagement with the valve seat and restrict flow of patient exhaled gases to the exhaled gas port, and the reduction of the activation pressure allows the bellows members to move the poppet face away from the valve seat and out of engagement with the valve seat to permit flow of patient exhaled gases to the exhaled gas port, thereby controlling the flow of patient exhaled gases from the valve.

  • Patent number: 10099025
    Abstract: The present invention connects to tubing through which gas flows to a patient. An alert notifies monitoring personnel that oxygen flow to the patient has been interrupted, because the tubing has been disconnected. The invention comprises an adapter that is connected to a gas or oxygen source and a nipple over which the tubing fits and through which oxygen flows to the patient. When the tubing becomes disconnected from the nipple, the oxygen flow actuates an alert. In one embodiment, the invention includes a fixed arm and a swing arm. A latch and a spring that pull the fixed arm and swing arm toward each other connect the two arms. When the tubing becomes disconnected, one arm rotates and activates a switch that sends a signal to an alert that is preferably audible.
