A respiratory therapy system configured to deliver gases to a patient can have a non-sealed gas flow generating arrangement configured to deliver a high flow of positive gas to an airway of a patient and a negative flow of gas away from an airway of the patient. The positive and negative flows of gas can be generated simultaneously. The flow of positive and negative gases reduces exhaled gases in anatomical dead spaces of the patient.

Gas therapy system for providing positive and negative gas flows

A system provides warm, humidified gas to a patient via a patient interface. Horizontal connections can be used between the humidification chamber and conduit. To reduce the likelihood of condensate flowing back to the humidification chamber, or dead space or gases recirculation regions occurring within the gases flow path, a raised portion is positioned inside of the flow path to improve flow characteristics and to provide a barrier for condensate back flow. The raised portion also reduces the amount of condensate that is formed in the system and provides better flow characteristics for sensing purposes.

Respiratory humidification system

A diffuser for use with a wound retractor and configured to deliver gases includes an interface tube for connecting to a gases supply and a diffuser interface positioned at a proximal end of the interface tube, the diffuser interface configured for delivering gases received from the gases supply through the interface tube, and the diffuser interface comprising a diffusion mechanism configured to deliver gases in a diffusion direction. A wound retractor with an integrated diffuser is also disclosed. The wound retractor includes an upper ring, a lower ring, a sleeve extending between and connecting the upper ring to the lower ring, and an integrated diffuser interface having a gases inlet and a diffusion mechanism.

Wound retractor and diffuser

A respiratory system provides conditioned respiratory gases to a patient within a controlled temperature environment. A humidification apparatus has an inspiratory tube that may extend to a patient interface. The inspiratory tube may have a reduced length. A thermal insulation component may insulate at least a portion of the inspiratory tube. As a result, less of the inspiratory tube may be exposed to the surrounding ambient environment, which may reduce condensate formation within the inspiratory tube and heat loss to the surrounding ambient environment. The humidification apparatus may be directly coupled to the controlled temperature environment.

Tubing for delivery of respiratory gases

The disclosure relates to medical tubes and methods of manufacturing medical tubes. The tube may be a composite structure made of two or more distinct components that are spirally wound to form an elongate tube. For example, one of the components may be a spirally wound elongate hollow body, and the other component may be an elongate structural component also spirally wound between turns of the spirally wound hollow body. The tube need not be made from distinct components, however. For instance, an elongate hollow body formed (e.g., extruded) from a single material may be spirally wound to form an elongate tube. The elongate hollow body itself may in transverse cross-section have a thin wall portion and a relatively thicker or more rigid reinforcement portion. The tubes can be incorporated into a variety of medical circuits or may be employed for other medical uses.

Medical tubes and methods of manufacture

High flow therapy is used to treat Cheyne-Stokes respiration and other types of periodic respiration disorders by periodic application of high flow therapy, adjustment of high flow therapy flow rates and/or periodic additions of CO2 or O2 into the air flow provided to the patient.

Breathing control using high flow respiration assistance

This invention relates to a surgical smoke evacuation system for use in removing gases and smoke created in surgical procedures form within an insufflated surgical cavity. Such a system comprises a discharge assembly adapted to form a gases path, and having an end which in use is located within said surgical cavity so that gases and/or surgical smoke inside said cavity can pass out of said cavity and through said discharge assembly along said gases path, a flexible discharge limb having an operational site end and an outlet end, and a self-supporting wall defining a gases flow passage between said operational site end and said outlet end, in use said open operational site end sealingly connected to said discharge assembly so that said gases and/or surgical smoke can pass out of said discharge assembly and into said discharge limb, a filter connected in use to the outlet end of the discharge limb, at least part of said wall of the discharge limb formed from a breathable material, said breathable material allowing the passage of water vapour through the wall of the discharge limb without allowing the passage of liquid water or surgical smoke or other gases.

Systems for laparoscopic surgery

Breathing assistance apparatus includes a gases supply unit adapted to, in use, deliver a stream of pressurised gases from an outlet. The gases supply unit is adapted to vary the pressure of the stream of pressurised gases. A supply path includes a flexible self-supporting gases transportation pathway having a first end connected to the outlet so that the gases transportation pathway receives the stream of gases and conveys the gases to a patient. A patient interface is connected to the second end of the gases transportation pathway receives a stream of gases. At least one sensor measures at least one information parameter of the supply path. A control system associated with the gases supply unit receives the information parameter. The control system contains reference data, and compares the received data to reference data, and determines a supply path based on the comparison.

Breathing assistance apparatus

Condensation or 'rain-out' is a problem in breathing circuits and especially neonatal breathing circuits. The subject patent provides an improved breathing tube component for managing rain-out particularly in neonatal applications. In particular the breathing tube has a smooth inner bore, and an outer insulating layer containing stagnant gas and a heater wire.

Breathing tube

A respiratory mask can have a frame supporting a sealing arrangement. Various features of the frame and sealing arrangement can improve comfort and reduce the occurrence of pressure sores. The frame can include cheek supports that have a large surface area configured to spread loads over a greater area of the patient's face and therefore reduce the forces applied to the face and the occurrence of point loads. The seal can have a main body that includes a spring with a silicone skin, wherein the spring applies a substantially constant force to the face and/or nares of the patient.

Respiratory mask with cheek supports

Interfaces for positive pressure therapy having a mask assembly, a headgear assembly and a connection port assembly are disclosed herein. The connection port assembly has a ball joint connection with the mask assembly and includes a quick release button for easily disconnecting the gases source conduit from the mask assembly. The mask assembly may include a bias flow vent that is formed separately and attached to the mask assembly. The headgear assembly encircles the rear region of the user's head and may include at least some portions that are substantially non-stretchable.

Respiratory interface

A respiratory mask can include one or a plurality of force sensors configured to detect a force imparted to a user's skin. Output from the one or more sensors can be represented in a way useful to the patient or healthcare provider for adjusting the mask to achieve a desired fitment. A representation of the detected forces can be displayed on a separate display device or on the mask.

Sealing force detection enabled, therapeutic fluid delivery device

Patient interfaces for respiratory therapy in the form of nasal interfaces or nasal masks include features that enhance or provide lateral stability of the interface. At least some of the embodiments provide multiple facial contact points or areas located in the general areas of the user's cheeks and/or upper lip. Some embodiments of the nasal interfaces provide advantageous sealing characteristics. The nasal interfaces may provide a controlled expiratory flow to reduce noise. Some embodiments include nasal pillows instead of or in addition to nasal prongs. The nasal pillows can have exhaust vents or can change in length in response to a pressure level within the nasal pillow.
