  • Patent number: 11857725
    Abstract: A patient ventilating (23) and aspirating system (8) is disclosed that has a suction tube (9) and connector (6) for connecting to a catheter mount that has a sealed passageway (15) The catheter mount passageway (15) is sealed with an elastomeric seal (16) including a perforation or slit (17). A connector (12) with a piercing member is associated with the suction tube (9). When the connector is attached to the catheter mount the piercing member (20) pierces the seal (16) such that the suction tube (9) can pass through the connector (6) and catheter mount.

  • Patent number: 9022036
    Abstract: A patient ventilating (23) and aspirating system (8) is disclosed that has a suction tube (9) and connector (6) for connecting to a catheter mount that has a scaled passageway (15). The catheter mount passageway (15) is sealed with an elastomeric seal (16) including a perforation or slit (17). A connector (12) with a piercing member is associated with the suction tube (9). When the connector is attached to the catheter mount the piercing member (20) pierces the seal (16) such that the suction tube (9) can pass through the connector (6) and catheter mount.

  • Patent number: 7157035
    Abstract: The present invention relates to delivery conduits used in systems that provide positive pressure ventilation therapy. In particular, the present invention relates to a sleeve that allows flexible conduits to be joined and sealed to a thermoplastic connector, allowing for gases to be supplied to the conduit. The sleeve is used in the over moulding of an end connector onto the conduit. The sleeve and method of attaching a connector to a conduit of the present invention has the advantage that it prevents the connector from loosening or breaking when the conduit is bent, pulled or stressed, which can occur in some cases where the connector is attached to the conduit using a bond, such as glue. Furthermore, the occurrences of flashing of plastic across the conduit walls will be prevented during moulding, ensuring that no air or water leakages occur within the conduit walls.

  • Patent number: 6953354
    Abstract: The present invention relates to the connections between respiratory humidifiers and/or other such devices and heated breathing conduits used to couple a patient to the humidifier. In particular, the invention is a connector to couple a gases supply means and a conduit, such that the connector causes there to be an electrical and pneumatic, that is, sealed connection between a conduit including an electrical wire extending within, throughout or about it and a gases supply device, such as a humidifier, blower or the like. The connector may be of a single port type or a dual port type. The dual port type connector is suitable for ventilator apparatus that have a dry line (dry breathing conduit) extending from a ventilator or blower that carries dry gas to a humidifier and an inspiratory limb that extends from the humidifier to the patient and carries humidified gases to the patient.
