CROSS-REFERENCE TO PRIORITY APPLICATION This application is the US national phase of international application number PCT/AU2004/001309 filed 24 Sep. 2004, which designated the U.S. and claims priority to U.S. Provisional Application No. 60/505,718 filed 25 Sep. 2003, the entire contents of each of which are hereby incorporated by reference.
The present invention relates to ventilators, e.g., continuous positive air pressure (�CPAP�) systems comprising a mask and an air flow generator, wherein the air flow generator is mountable to the mask's wearer. In one embodiment, the present invention provides CPAP systems wherein an air flow generator is mounted on the mask. In other embodiments, the air flow generator may be provided to the body of the wearer, e.g., the arm, leg, chest or waist, and a short air delivery tube can be used to connect the mask with the air flow generator.
There are two main sources of instability of a mask system during use or sleep. Normal patient movement can create instability, for example, a patient rolling on his or her side, which may cause the mask to interfere with the bedding material. Another concern of using an air delivery tube that is connected to an apparatus away from the patient is so-called �tubing drag�, which refers to a drag force on the air delivery tube which is draped over the back or side of the bed. Tubing drag can be created or complicated by movement of the wearer. Tubing drag may cause relative movement between the mask seal and the patient's face during the CPAP administration and produce leaks and/or discomfort.
SUMMARY OF THE INVENTION Aspects of the present invention include addressing the concerns in the art, e.g., by reducing or eliminating the risk of tubing drag during CPAP administration.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a CPAP system according to one embodiment of the invention;
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS A CPAP system includes a mask and an air flow generator, wherein the air flow generator is provided to a wearer of the mask. In one embodiment, the air flow generator is mountable to a wearer's body (including a wearer's clothing). In another embodiment, the air flow generator is mounted on or provided to the mask.
Referring to FIG. 2, air flow generator 20 includes, for example, a first part 90 and a second part 80 that are joined, e.g., by screws 130 through bores 134 and 136 to form a housing for impeller 120 and motor 100. The parts 80 and 90 may be made from a variety of materials, for instance from cured resinous materials, from metal (e.g. aluminum), or from polymers, e.g. from polyolefins (such as polyethylene or polypropylene), polycarbonates, or acrylonitrile-butadiene-styrene polymers (�ABS�).
In yet another variant (not shown), the motor assembly may be mounted or provided or combined to a headgear system, with short tubing running to the mask. The headgear system could act as form a of vibration damping. Motors invariably vibrate due to imbalances or during motion. Isolating this vibration from the wearer will reduce irritation and noise. As the head is sensitive to vibration, some form of motor and/or impeller isolation is preferable. A damping system may be used; for example a visco-elastic/soft foam �cushion� between the head and flow generator would provide some benefit.
