A cannula plugging device for rehabilitation after tracheotomy relates to the field of medical devices. The cannula plugging device includes a plugging device bracket. An outer wall of the plugging device bracket is fitted with a ring-shaped outer airbag. An inner wall of the plugging device bracket is fitted with a ring-shaped inner airbag. Two inflation tubes connecting the outer airbag and the inner airbag respectively are fitted on the plugging device bracket. The present invention makes the outer airbag and the inner wall of tracheotomy cannula pressed together by inflating the outer airbag. By gradually inflating the inner airbag and adjusting the size of the inner diameter of the lumen, the opening of the trachea gradually changes, so that the patient can gradually adapt to the process of plugging the cannula.

The disclosure relates to the field of medical instruments, and discloses a control device and method for a ventilation therapy equipment, and ventilation therapy equipment. The ventilation therapy equipment has multiple working modes. The control device includes an identification device used for identifying a type of an accessory of the ventilation therapy equipment; and a controller used for determining and controlling, according to the identified type of the accessory, the ventilation therapy equipment to switch to a working mode corresponding to the type of the accessory. The control device can automatically switch the corresponding working modes according to different types of accessories, and is more convenient and intelligent, so that a lot of time can be saved for a doctor and a patient.

An irrigating intraluminal suction inner cannula system for a tracheostomy tube may be a suction-powered system that may be used for suction alone or a combination of rinse and intraluminal suction for tracheostomy tubes in place of conventional catheter-based intraluminal suction. An inner cannula includes chambers, or regions, and holes that facilitate intraluminal suction and cleaning at multiple locations within the tracheostomy tube. It may be applied/actuated by a patient, healthcare worker, caretaker, or via an electronic system either on-demand or on regular or triggered intervals, in either inpatient/hospital or outpatient/ambulatory care setting.

A portable humidification apparatus for a patient having a tracheostomy including a tracheostomy tube includes an adapter having a central lumen and arranged to be coupled to the tracheostomy tube, the adapter including a first magnet disposed therein. A vaporizer assembly is configured to be removably coupled to the adapter in fluid communication with the central lumen and includes a second magnet disposed therein. The first magnet and the second magnet releasably connect the adapter and the vaporizer assembly and allow for relative rotation between the adapter and the vaporizer assembly when connected. An ultrasonic emitter is disposed within the vaporizer assembly for generating a water mist from water in a water supply system in fluid communication with the vaporizer assembly, wherein the water mist is ducted from the vaporizer assembly to the central lumen of the adapter to provide humidification of air inspired by the patient through the tracheostomy tube.

Some implementations of the disclosure are directed to a balloon dilator system, including: a balloon pump hand piece configured to pump pressurized fluid through a flexible tube to inflate an inflatable balloon, the balloon pump hand piece comprising: an attachment mechanism for removably coupling the balloon pump hand piece to a proximal end of an endoscope; the flexible tube, wherein the flexible tube is configured to be in fluid communication with the balloon pump hand piece at a first end of the flexible tube, and the inflatable balloon at a second end of the flexible tube; a hollow inner cannula; and the inflatable balloon, wherein the inflatable balloon is external to and circumferentially attached to the hollow inner cannula between the proximal end of the hollow inner cannula and the distal end of the hollow inner cannula.

A method for designing a cannula for a patient, wherein a processing unit is configured to implement following steps: a) generating a 2D or 3D numerical representation of the trachea of the patient in at least one position, b) identifying a set of anatomical landmarks, c) considering a 2D or 3D numerical representation of a cannula based at least on the landmarks, d) numerically simulating all or a part of an insertion of the cannula into the trachea, e) estimating at least one reciprocal conflict metric between the cannula and the trachea during the insertion, f) changing the cannula when the estimated conflict metric do not meet predetermined conflict criterion, and iterating at least one of the preceding steps until a cannula is found for which the estimated conflict metric meets the predetermined conflict criterion.

Respiratory systems with a flow generator can provide bubble CPAP therapy by controlling the pressure of a flow of gas delivered to a patient. The controller of the respiratory system can control a motor speed of its flow generator so as to control the pressure of the flow of gas. The controller can also detect presence of bubbling and/or possible leaks in the gas pathway of the system. The respiratory system can include a high flow respiratory system.

A breathing assistance system for delivering a stream of heated, humidified gases to a user, comprising a humidifier unit which holds and heats a volume of water, and which in use receives a flow of gases from a gases source via an inlet port, the flow of gases passing through the humidifier and exiting via an exit port, the system further having a temperature sensor which measures the temperature of the gases exiting the humidifier unit, an ambient temperature sensor which measures the temperature of gases before they enter the humidifier unit, and a flow sensor which measures the flow rate of the gases stream, the system also having a controller which receives data from the temperature and flow sensors, and which determines a control output in response, the control output adjusting the power to the humidifier unit to achieve a desired output at the humidifier unit exit port.

A device for sealing a tracheostoma in a patient includes a seal member for insertion through the tracheostoma to a trachea. The seal member includes a disc having a predetermined line of weakness. In a first configuration, the seal member forms a seal by being pulled against the tracheostoma. In a second configuration, the seal member is removed from the trachea through the tracheostoma by breaking along the line of weakness.

A method of, or system for, ventilating lungs in breathing and non-breathing patients—including applications for anesthesia—may comprise maintaining an inspiratory flow rate at an inspiratory setpoint at a low flow setting. Lung pressure in a patient may be regulated between a high pressure setpoint and a low pressure setpoint with periodic expiratory flows and continuous inspiratory flow. An expiratory control valve may be adjusted to an open position when a lung pressure is at or above a high pressure setpoint. An expiratory control valve may be adjusted to a closed position when a lung pressure is at or below a low pressure setpoint. Concurrent venting outflow and CO.sub.2 offloading through flow within the lungs may be facilitated by providing an intermittent expiratory flow to the patient while providing the continuous inspiratory flow.
