Problems solved by technology

However, because of the possibility of leakage, the flexibility of the invention in orientation limits the volume of water that the reservoir can store relative to the total volume available in the reservoir
In turn, this limitation limits the total volume of air that can be humidified during a treatment session without the need to refill the reservoir

Embodiment approach

[0016] In this document, a reference to "comprising" is a reference to "comprising", where both words are used in a non-limiting context. The present invention is best understood by referring to the accompanying drawings. It is to be understood that the drawings are intended to be illustrative embodiments of the invention and that the scope of the invention defined in the claims includes other embodiments not so shown.

[0017] The present invention provides a means for preventing water from escaping by splashing or leaking from an opening of a reservoir through which gas flows for humidification prior to delivery to a subject. Preferably, the means is a baffle. Figure 1a with Figure 1b Two perspective views of a gas delivery device 10 incorporating a water reservoir 2 with a baffle 1 are shown. exist Figure 1a A cross-section of the gas delivery device 10 is shown in a side perspective view. It can be seen that the reservoir is sloped in this embodiment. A conduit 3 en...

Abstract

TThe present invention provides a water reservoir for humidification of the gas delivered by a gas-delivery device. The water reservoir comprises of a container having at least one opening for gas movement, and a means to prevent water escape through the aperture while allowing passage of gas to be humidified and delivered to a subject. Preferably the means to prevent water escape is a baffle. Preferably the baffle is disposed opposite at least a portion of the opening. The baffle may be continuous with a wall of the container. The container may be comprised of a deformable material.

Description

technical field [0001] The invention relates to a water reservoir for humidification of an air flow in a gas delivery device. Background technique [0002] There are a variety of devices available for delivering breathable gas to a patient for the treatment of sleep-disordered breathing. For example, in the treatment of obstructive sleep apnea, air is usually delivered as continuous positive air pressure (CPAP), in which air is continuously supplied through a mask at a pressure higher than that around the nose of the sleeping patient to maintain the patient's breath. The airway is open for efficient breathing. [0003] For continuous therapy benefiting from pressurized gas, it is important to deliver air and other gases at a pressure and flow rate appropriate to the desired breathing pattern. Further patient comfort is enhanced if the air is humidified. An advanced example of a CPAP device is described in the patent application published as WO 2007 / 045017 for a device for...
