  • Patent number: 10456548
    Abstract: Resuscitator devices including inflation control devices and the inflation control valves can prevent an excessive number of breaths per minute during manual resuscitation from being delivered to a patient. The inflation control valves are inlet valves for a resuscitator device having a flexible chamber that extends from a first end to a second end, the second end being configured to attach to an airway adjunct. The valve housing may be configured to be disposed about the first end and to receive air for inflating the flexible chamber, the valve housing being partially disposed within the flexible chamber. The inflation control member may be configured to control inflation rate of the flexible chamber, the inflation control member being disposed within the valve housing and movable with respect to the valve housing.

  • Patent number: 10245401
    Abstract: A subglottic suctioning system with a tracheal tube having a ventilation lumen, a cuff inflation lumen, and a suction lumen are disclosed which may help reduce the incidence of ventilator associated (or acquired) pneumonia. The suction lumen communicates with the space in the trachea above the cuff where secretions accumulate. The suction lumen has a valve on the proximal end for connection to a source of vacuum. The valve is adapted to interrupt the supply of vacuum to the suction lumen to allow for the introduction of a rinsing fluid in its place and to automatically re-establish the connection to the source of vacuum upon completion of rinsing. The rinsing fluid aids in maintaining an open suction lumen and may include medicaments and mucolytic agents to enhance or promote healing or to alter the properties of the mucus to make removal easier. The user may easily and repeatedly alternate suction and rinsing fluid through the suction lumen, i.e.

  • Patent number: 10245406
    Abstract: A method of providing a breath to a human patient having a patient connection connected by a patient circuit to a ventilator device. The method includes delivering both a bolus of oxygen and breathing gases including air to the patient circuit. The patient circuit conducts the bolus of oxygen and the breathing gases to the patient connection. The breathing gases are delivered before an end of the inspiratory phase of the breath. The bolus may be delivered at or before a beginning of an inspiratory phase of the breath, and the delivery of the bolus may be terminated before the end of the inspiratory phase of the breath. The bolus and breathing gases are delivered to the patient circuit via different ventilator connections that isolate the bolus from the breathing gases before they enter the patient circuit.

  • Patent number: 10188812
    Abstract: A nose clip includes an outer support member adapted to contact an outside surface of a nose; a bridge connected at a first end to the outer support member; and an inner support member connected to a second end of the bridge and adapted to be inserted into the nostril and to contact an inner surface of the nostril. When inserted, tension generated between the outer support member and the inner support member causes lateral movement of a surface within the nostril and opens a nasal airway. Additionally, the inner support can be curved to create an outward movement of the lateral wall of the nose. This in turn enables improved breathing. The nose clip may be made of a malleable material. The inner support member may include extensions that are malleable. The inner support members may be bent so that they create a convex contour of an interior surface of the nasal cavity.
