Abstract: The present invention relates to improved protective pleated facial masks or respirators that comprise a pleating spacer that is adapted to enter into, and stably separate the folds of one or more of pleats of a pre-pleated mask or respirator filter, or a pre-pleated filter layer thereof. The present invention also relates to improved protective pleated facial masks or respirators that comprise a pleating spacer that is adapted to stably form one or more pleats in an initially unpleated filter of a facial mask or respirator, or a filter layer thereof. The pleating spacers of the present invention thus act to increase the effective surface area of the filters of such masks or respirators, and thereby improve airflow while preserving the ability of the mask or respirator to protect the wearer from hazardous agents.

Abstract: A flow regulating valve for a respiratory treatment system is disclosed, as well as a vent arrangement comprising the flow regulating valve. The flow regulating valve may include an inlet, an outlet, and a variable conduit in fluid communication with the inlet and the outlet.

Abstract: A face mask for delivering oxygen to, and sampling carbon dioxide exhaled from, a subject includes a partition wall that divides the mask into a subject respiratory space that primarily contains carbon dioxide exhaled by the subject, and an oxygen reservoir space that primarily contain oxygen. The partition wall includes one or two holes to which naris conduits are respectively connected. The naris conduit are positioned in proximity to the subject's nares to closely obtain carbon dioxide samples. The naris conduits enable oxygen to flow from the oxygen reservoir space to the subject respiratory space during inhalation, while quickly expelling traces of CO2, and they configured such that exhaled CO2 quickly fills them up, during exhalation, and while expelling oxygen traces back to the oxygen reservoir space. During exhalation.

Abstract: A respiratory gas delivery system monitors gas flow over the course of a breath in real time and uses this parameter to simulate, in whole or part, the function of a reference respiratory gas delivery system, in particular structural features, particularly structural components of parts of the reference system, to overcome a structural limitation of the reference system.

Abstract: A method of monitoring patient use of an endotracheal tube with a ventilator includes receiving in a controller, such as in a stand-alone monitoring device or in the ventilator itself, force data indicative of a biting force of the patient on the endotracheal tube, wherein the force data is based on force signals generated by a force sensor coupled to the endotracheal tube (e.g., either directly or by way of a bite block). The method further includes analyzing the force data in the controller, and determining in the controller from the analyzing of the force data that the force data is indicative of one or more of: (i) at least a predetermined threshold level of agitation or discomfort of the patient, and (ii) a current or likely attempt to self-extubate by the patient.

Abstract: An aerosol-generating system may include an electrical power supply, an electrical heater connected to the electrical power supply, and a substrate container. The substrate container may define a blind cavity containing an aerosol-forming substrate in the form of a gel that is a solid at room temperature. The electrical heater is external to the substrate container and configured to heat the substrate container to generate a vapor without contacting the aerosol-forming substrate. As result, the possibility of unwanted materials building up on the electrical heater can be reduced, thereby providing a more reliable and consistent performance.

Abstract: Oral gas catheters and methods of inducing gas in a patient orally. The oral gas catheter includes one or more delivery cannulas configured to be inserted into the patient's mouth with a distal end of the delivery cannula disposed adjacent the patient's laryngeal inlet, and a clip disposed on the delivery cannula.

The oral gas catheter may have two such delivery cannulas and clips with the delivery cannulas coupled together by a coupler. The delivery cannulas are placed in an operative position in a patient's mouth and secured in the operative position by releasably securing the clips to the patient's teeth. The oral gas catheter makes it possible to bypass the nasal cavity and deliver oxygen or other gas directly adjacent the laryngeal entrance and into an anatomical dead space of the airway.
