11690970 · 2023-07-04 · ·

Dispensing systems for a ventilator circuit having a ventilator flow circuit with a normal inhalation flow path with a heat and moisture exchanger (HME), a flow sensor in communication with the ventilator circuit, an automated drug dispensing system with an actuator and a pressurized canister residing upstream of the HME, a bypass inhalation flow path residing downstream of the pressurized canister, and at least one electromechanical valve residing in the inhalation flow path to selectively open the valve which can be normally closed to define a closed bypass path. At least one controller opens the at least one electromechanical valve to open the bypass inhalation flow path and close the normal inhalation flow path through the HME only when the flow sensor indicates air flow is in an inhalation direction. Once the valve is open, the actuator dispenses medication through the bypass inhalation flow path to the patient.

Ventilation system

A respiration device (1) supports cardio-pulmonary resuscitation (CPR) and a method for operating a respiration device (1) supports cardio-pulmonary resuscitation (CPR). The respiration device (1) has a control and regulation unit (7) in order to actuate an expiratory metering unit (3), and an inspiratory metering unit (2) such that, in a first phase, a current value of pressure is increased relative to a first pre-defined value (16) and such that, in a second phase, the current value of the pressure is reduced relative to the first pre-defined value (16).

Artificial airway management devices, systems and methods
11541195 · 2023-01-03 · ·

Systems and methods for cleaning and maintaining artificial airways sized for insertion within pediatric or neonatal patients (e.g., external diameters of less than 5 mm) are disclosed. The system includes a multi-port ventilator manifold configured to couple to a ventilation source, thereby forming a ventilator circuit with the patient. The manifold includes an occluder configured to advantageously reduce an amount of dead space in the manifold so as to prevent loss of positive end expiratory pressure of the ventilator circuit and reduce the likelihood of broncho-pulmonary dysplasia of the patient, or even premature death.

ADJUSTABLE HEADGEAR TUBING FOR A PATIENT INTERFACE

Aspects of the present technology comprise a positioning and stabilising structure to hold a seal-forming structure in a therapeutically effective position on a head of a patient. The seal-forming structure may be constructed and arranged to form a seal with a region of the patients face surrounding an entrance to the patients airways for sealed delivery of a flow of air at a therapeutic pressure of at least 4 cmH2O with respect to ambient air pressure throughout the patients respiratory cycle in use. The positioning and stabilising structure may comprise a front hoop arranged to contact, in use, at least a region of the patients head superior to an otobasion superior of the patients head and a rear strap. The positioning and stabilising structure may comprise an adjustment mechanism for adjustment of the front hoop and the rear strap relative to the patients head, the adjustment mechanism being arranged in a single operation to adjust both the front hoop and rear strap to enable the positioning and stabilising structure to fit different size heads.

NASAL CANNULA

A nasal cannula includes a first tube, a second tube, a nasal connector tube, and a flow splitter. The nasal tube has first and second ends, the first end connected to a distal end of the first tube, the second end connected to a distal end of the second tube. First and second nasal prongs extend from and are fluidly coupled to the nasal connector tube. The flow splitter has an input and first and second outputs. The first output of the flow splitter is connected to a proximal end of the first tube. The second output of the flow splitter is connected to a proximal end of the second tube.

SYSTEMS AND METHODS FOR HYPOXIA

Systems and methods for hypoxia delivery are provided. An apparatus for providing intermittent normoxia and hypoxia intervals includes a breathing component, a normoxia fluid source, a hypoxia fluid source, a valve, and a control system. The valve is configured to disrupt flow from at least one of the normoxia fluid source and the hypoxia fluid source and the control system is configured to cause the at least one valve to switch between delivery of fluid from the normoxia fluid source and the hypoxia fluid source while maintaining positive pressure at the breathing component.

POSITIVE DISPLACEMENT VENTILATOR FOR BREATHING ASSIST

Embodiments of the innovation relate to a ventilator, comprising: a positive displacement pump having a drive motor and configured to output a predetermined volume of inspiratory gas for each rotation of an output shaft of the drive motor; at least one pressure sensor configured to measure inspiratory pressure; and a control unit having a controller comprising a memory and a processor, the control unit disposed in electrical communication with the drive motor and with the at least one pressure sensor. The controller is configured to: receive at least one of an operation signal and a pressure sensor signal, and transmit a drive motor control signal to the drive motor to adjust at least one of a rotational speed of the output shaft and a number of rotations of the output shaft based upon the at least one of the operation signal and the pressure sensor signal.

Fluid plug for sterile processes and methods of using the same
11530772 · 2022-12-20 · ·

A fluid plug for use with sterile processes such as the manufacture or production of pharmaceuticals and biologics is disclosed. The fluid plug is made of a material or materials that will tolerate sterilizing processes such as gamma irradiation. The fluid plug is used to selectively plug the ends of flexible polymer conduits that may be connected to fluids, reagents, or products used or generated as part of the manufacturing process. Also disclosed is the use of the plugs in combination with a series of valves in a block-and-bleed arrangement to enable the sterile transfer and connection of fluids, reagents, or products within a process flow.

Combination respiratory therapy and mattress functionality system integrated into a patient bed

A patient support apparatus includes a bed including a frame. A mattress is supported by the frame. A respiratory therapy apparatus is supported by the frame. A pneumatic system is operable to inflate at least one bladder of the mattress and operable to deliver air to the respiratory therapy apparatus.

Dry powder delivery device and methods of use

A dry powder aerosol delivery device and related methods for delivering precise and repeatable dosages to a subject for pulmonary use is disclosed. The dry powder aerosol delivery device includes a housing, a cartridge, and a dry powder dispersion mechanism, and at least one differential pressure sensor. The dry powder delivery device is automatically breath actuated by the user when the differential pressure sensor senses a predetermined pressure change within housing. The dry powder aerosol delivery device is then actuated to generate a plume of particles having an average ejected particle diameter within the respirable size range, e.g., less than about 5-6 μm, so as to target the pulmonary system of the user.
