A nasal ventilation mask supplies breathing gas to an airway of a patient. The mask has a housing defining an internal cavity and having a peripheral end defining an end opening. The end opening is in fluid communication with the internal cavity, and the end opening is configured to be positioned over an airway on a face of a patient. The housing further defines a connector segment having a receiver member. The connector member defines a top wall defining an outer periphery. The receiver member has a portion extending past the outer periphery. The receiving member has an opening in fluid communication with the internal cavity. The mask also has a sealing member operably connected to the housing proximate the end opening. The sealing member is configured to abut the face of the patient, and the receiver member is configured to be operably connected to a supply of breathing gas.

A patient treatment system includes a ventilation bag, and a monitoring device which is configured so as to be connectable to the ventilation bag. The monitoring device measures the pulse rate derived from the heart rate of a neonate, from signals of ECG electrodes which are connected to the monitoring device. In a case where an abnormality of measurement information of the pulse rate is detected, the monitoring device notifies of first information prompting ventilation by the ventilation bag.

A portable respirator as described may include an inflatable bag and a respirator body. The inflatable bag may be arranged to provide air to a patient through a face mask or an endotracheal tube in response to compression/retraction actions applied to the inflatable bag. The respirator body may include a first cover portion and a second cover portion arranged to enclose moving components of the portable respirator and define a substantially circular opening for the inflatable bag to be fitted through, a motor, a pair of levers positioned on opposing sides of the substantially circular opening, and a cam mechanically coupled to the motor and arranged to move the pair of levers in response to a rotation action by the motor such that the pair of levers apply the compression/retraction actions to the inflatable bag fitted through the opening.

A pressure safety device is used with a bag valve mask (BVM) for preventing over-pressurization. The BVM includes a bag assembly having a bag connector for detachably mating to a mask connector on a patient mask. The pressure safety device has a housing with a bag port, a mask fitting, and a flow path from the bag port to the mask fitting. The bag port detachably connects to the bag connector on the BVM, and the mask fitting detachably connects to the mask connector on the BVM. The pressure safety device includes an automatic flow reduction valve located on the flow path in the housing and impedes flow when pressure on a bag connector side of the valve exceeds a maximum threshold value.

Embodiments of the present invention provide systems and methods for delivering respiratory treatment to a patient. For example, a treatment system may include a mechanism for delivering a positive pressure breath to a patient, and one or more limb flow control assemblies which modulate gas flow to and from the patient. Exemplary treatment techniques are embodied in anesthesia machines, mechanical ventilators, and manual ventilators.

A respiratory device provides respiratory support to a patient. The respiratory device includes an expandable bag and a rigid valve housing. The expandable bag has an air inlet valve as well as a first and second sides that are bounded, respectively, by first and second rigid side panels. Each of the first and second rigid side panels includes a biasing member projection. The rigid valve housing is in fluid communication with the expandable bag. The rigid valve housing includes an adjustable tidal volume control device that interfaces with the biasing member projection of each of the first and second rigid side panels to set one of a plurality of predetermined tidal volumes for the expandable bag in an uncompressed or compressed configuration. The rigid valve housing additionally includes a patient breathing interface connection member.

A surgical system includes an endotracheal system and intubation system. The intubation system includes an introducer rod and intubation instrument. The intubation instrument includes: an esophageal tube, intubation tube, endoscopic camera tube, and balloon located distally beyond a distal end of the intubation tube. The introducer rod is insertable through the intubation tube to a position where an endoscopic camera in the endoscopic camera tube has a line of sight to a distal end of the introducer rod. The balloon is movable from a deflated condition to an inflated condition in which the balloon fully occludes the esophageal opening to block advancement of the introducer rod into the esophagus and urge the introducer rod into the trachea. The intubation tube is removable from the patient leaving behind the introducer rod, such that the introducer rod is guides an endotracheal tube of the endotracheal system into the patient's trachea.

Resuscitation/ventilation systems that include a pressure chamber or cylinder may use a piston articulated within the pressure chamber or shaft to push air and/or a mixture of gas and air into and out of an airway circuit for the purpose of providing mechanical ventilation and/or artificial respiration to a patient. In some cases, the pressure chamber or cylinder may be resident within a canister that fits with a body. The canister may include a motor that moves a shaft connected to the piston up and down, or in and out, within the pressure chamber or cylinder and this movement of the piston may cause a vacuum within the airway circuit and/or the pushing of air or gas out of the airway circuit into a patient’s lung(s).

A one or more plane, variable camshaft is described. The single plane camshaft includes a circular drive plate with two radial drive slots on opposing sides of the center, four arms movably coupled at respective endpoints and arranged in a polar configuration, and a scroll plate to allow adjustable operation of the camshaft. Multiple plane camshafts may include a number of half drive plates arranged around a drive block and secured to a base washer through a scroll block. The variable camshaft may be incorporated into portable, motorized or manual, bag valve mask based resuscitation devices or similar ones.

The self-inflating bag control system is characterized in that it comprises a bag controlling valve which is connected to at least two gas pumps and at least one gas parameter sensor via the gas distribution tubes. It comprises at least one gas pressing device connected to the valve via a gas parameter sensor via gas flow tubes. A control unit with a control panel is connected to the system through a gas sensor, which includes a sub-unit for setting the parameters of the gas flowing into the self-expanding bag, a measuring and analyzing the parameters of the gas flowing in the system by measuring the pressure and volume of the gas from the as parameters sensor, and a warn-alarm sub-unit, which generates a warning and/or alarm signal on the basis of the gas parameters read from the measurement and analysis subunit.
