A respiratory therapy apparatus is operable to deliver multiple types of therapy to a patient. The apparatus includes a main housing and a nebulizer tray that selectively attaches to a bottom of the main housing. The apparatus also includes a filter housing unit having an antenna surrounding a pneumatic passage and a transponder chip coupled to the antenna. The main housing has also has an antenna that surrounds a respective pneumatic passage of a main outlet port of the apparatus. The main housing includes a reader that controls communication between the antennae. The main housing of the apparatus also has a pivotable hose support plate, a firmware upgrade port underneath part of the top wall of the housing, and a graphical user interface (GUI) that displays various user inputs for control of the apparatus and that displays various alert conditions that are detected.

A suction device includes a negative pressure generator, a connector and a mask; the negative pressure generator comprises a housing and a piston rod, wherein the housing is internally provided with a cavity, an upper end of the housing is provided with an avoidance hole communicated with the cavity, and a lower end thereof is provided with an opening communicated with the cavity; the piston rod comprises a push-pull rod and a piston sleeved on the push-pull rod, an upper end of the push-pull rod runs through the avoidance hole, and the piston is movably and hermetically connected to an inner side wall of the housing by means of a sealing ring; an upper side of the mask is provided with a through first connecting cylinder, and a lower side thereof is provided with a flexible annular pad configured to fit with the face.

A system for sterilization of a medical device comprising at least one medical device and at least one sterilization device. The sterilization device comprises at least one plasma generator and at least one water source and/or water vapor source for providing water and/or water vapor. The sterilization device is configured to generate plasma-activated water vapor and the system is configured to at least partially conduct the plasma-activated water vapor through the medical device.

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.

An automatic control system for a tracheobronchial-air stimulation device intended to be connected to a subject. The stimulation device is configured to generate a set of negative pressure pulses during a relaxed exhalation of the subject. Also, a method for automatically controlling the tracheobronchial-air stimulation device, and a computer program and non-transitory computer readable medium, each of which comprise instructions for implementation of the method.

A portable medical ventilator using pulse flow from an oxygen concentrator to gain higher oxygen concentration includes a positive pressure source to deliver pressurized air to the patient and a negative pressure source to trigger the oxygen concentrator. A patient circuit attached to a patient interface mask connects the ventilator to the patient. The ventilator includes a controller module that is configured to generate a signal to the negative pressure device to trigger the concentrator to initiate one or more pulses of oxygen from the oxygen concentrator. The oxygen pulses are delivered to the patient interface directly through multi-tube or a multi lumen patient circuit. The oxygen does not mix with air in the ventilator or in the patient circuit and bypasses the leaks in the patient circuit and/or patient interface.

The invention relates to a ventilator comprising a gas source, at least one gas path and a patient conduit and at least two valves, each of the valves having at least indirectly a port for the surrounding air and each of the valves being at least temporarily connected to the gas source and/or the patient conduit so as to conduct gas.

A biocontainment assembly for use with a patient suspected of having or diagnosed with a transmissible disease(s) capable of respiratory, airborne, contact, or droplet transmission includes a housing configured to be positioned over and at least partially enclose a head, neck, and/or torso of the patient. A sidewall of the housing includes an open portion contiguous with an at least partially pen bottom portion of the housing, sized to fit over at least a portion of the head, neck, and/or a torso of the patient. The housing also includes an airflow opening for evacuating fluid from an interior defined by the housing. The assembly also includes a drape configured to extend across the open portion of the sidewall having a first portion removably connected to the housing and an opposing second portion configured to be draped over the torso, abdomen, waist, and/or legs of the patient.

A respiratory system, primarily to provide a mechanical insufflation/exsufflation therapy, may include a first pressure generating source, a second pressure generating source and a primary valve to switch between insufflation/positive pressure flow and exsufflation/negative pressure flow, and to generate oscillations alongside either of these cycles. The respiratory system can optionally employ a secondary valve either on a fluidic path of the first pressure generating source or on a fluidic path of the second pressure generating source. An interfacing assembly acts as a fluidic conduit between the pressure generating sources and the patient. A control unit is configured to generate required pressurized flow and oscillations as per the user settings. The aforesaid valves can be manipulated into multiple orientations/positions, which are aligned and/or adjusted with respect to the respective pressure generating sources as per the therapy requirements.

The present system (10) comprises a subject interface (22), a segmenter (12), a loosener (14), sensors (18), and computer processors (28). The segmenter is configured to selectively control gas flow through the subject interface to provide high amplitude pressure oscillations (44) during exhalation such that the high amplitude pressure oscillations aid cough productivity in the subject. The loosener controls gas flow through the subject interface to provide low amplitude pressure oscillations (43, 63) during inhalation (48, 68) and exhalation (49) such that the low amplitude pressure oscillations loosen respiratory secretions. The computer processors detect trigger events based on the output signals such that the one or more trigger events include a loosening trigger event and a segmenting trigger event (66); and responsive to detecting the loosening trigger event, control the loosener to provide the low amplitude pressure oscillations, and, responsive to detecting the segmenting trigger event, control the segmenter to provide the high amplitude pressure oscillations.
