Abstract: A respiratory mask includes a frame and a cushion module including a housing and a cushion that seals on a user's face in use. The housing includes a first connector, for example, a female connector, and the frame includes a second connector, for example, a male connector. The first and second connectors are coupled together in use. The housing includes one or more fasteners that secure the male connector to the female connector. Each fastener includes a base portion coupled to the housing and a moveable portion pivotally connected to the base portion. To assemble the mask, the male connector is inserted into the female connector such that the male connector engages the fasteners. Advancement of the male connector into the female connector causes the fasteners to change orientation from a neutral position to a toggled position and compress. The compressed fasteners apply a retention force to the male connector.

Abstract: Ventilator system with multiple inspiratory lumens is provided. The inspiratory lumens are configured so that separate inspiratory lumens provide inspiratory gas mixtures to separate portions of a patient's airways, for instance to separate lungs and/or bronchi. The ventilator system can include one or more expiratory lumens to evacuate expiratory gases from airways. The use of separate inspiratory lumen(s), with expiratory lumen(s), allows for functional separation of structural portions of the lungs, and maintenance of continuous or almost continuous flow through at least part of respiratory cycle via inspiratory and expiratory lumens. This can further reduce dead space and clear suspended therein diseases causative agents with improvement in outcomes, reduce risk of cross-contamination or cross-infection between different parts of airways, for example such as cross-infection from one lung lobe to another lobe or.

Abstract: A portable ventilator device suitable for emergency use, such as cardiac pulmonary resuscitation and well as ventilation in non-cardiac induced medical events. The device is connected to a display screen that receives simple inputs from an operator, including height, weight, or sex of the distressed patient, but does not require input of more complicated variables, such as tidal volume, respiratory rate, inspiratory airflow, or positive end-expiratory pressure. Based on the input height, weight, and/or sex, the device automatically correlates the input values with probably values for tidal volume, respiratory rate, inspiratory airflow, or positive end-expiratory pressure, based previous data point correlations. The device then begins delivering air from a ventilator to the patient based on the estimated, correlated values. While the device utilizes simple inputs, it still capable of operating in multiple modes with both pressure control and volume control.

It is portable, operates using an electric power source only, easy to wear, fits different hand sizes, and most of its parts made of lightweight plastic.

Abstract: Traditionally, vital signs monitors in the veterinary setting have been designed for use with human subjects that have simply been repurposed for use in the veterinary space. While some changes may be made to the human monitor to make it more amenable for veterinary use (e.g., changing the monitor display options from “adult” and “pediatric” to “large animal” and “small animal”), these changes are generally only done on a superficial level and thus omit significant veterinary-specific functionality that might otherwise be obtained. Further, vital signs monitors do not include a pre-procedure checklist or any functionality to increase safety awareness and allow clinics to ensure compliance with certain pre-procedure protocols. Accordingly, it is a purpose of the present invention to provide a veterinary-specific vitals signs monitor that overcomes these traditional limitations and increases the ease and efficiency with which veterinary care can be delivered.

The robot module assists an affected upper limb with rehabilitation exercise. The comprehensive affected upper limb muscle signal acquisition and processing module acquires and obtains a comprehensive assessment of the affected upper limb. The rehabilitation training evaluation module is used for processing and analyzing the comprehensive assessment of the affected upper limb, so as to obtain a quantitative evaluation of the affected upper limb during rehabilitation training.

Abstract: A humidifier for delivering humidified gases to a patient includes an inlet, an outlet, a gases flow path extending from the inlet to the outlet, a permeable wall, a liquid reservoir, and a heater. The permeable wall separates the gases flow path from the liquid reservoir. The heater heats liquid stored in the liquid reservoir to form vapour, and the vapour passes through the permeable wall to the gases flow path to humidify gases in the gases flow path. Another inline humidifier for delivering humidified gases to a patient includes an inlet and an outlet and holds a tape made of hydrophilic or hygroscopic material. The tape is pre-soaked with water and can include a heating element. The heating element heats the tape and the stored water to release the stored water as vapour and thereby humidify gases passing through the inline humidifier.
