Description

Respiratory mask and ventilation therapy equipment

Technical Field

The utility model relates to a treatment equipment field of ventilating specifically relates to a respiratory mask and treatment equipment of ventilating including this respiratory mask.

Background

The non-invasive positive pressure ventilation method is widely applied to the treatment of Obstructive Sleep Apnea (OSA), chronic obstructive emphysema (COPD) and other diseases. It is no longer necessary to surgically insert a tube into the patient's airway, but rather a continuous pressure ventilation (CPAP) or a variable pressure ventilation is delivered to the patient's airway by a blower through tubing and a patient interface device.

Patient interface devices in non-invasive ventilation therapy are typically respiratory masks of the types nasal masks, oronasal masks, nasal pillow masks, and full face masks. A typical configuration of a respiratory mask includes a frame, a cushion secured to the frame and forming a gas chamber with the frame, an elbow connected to the frame for delivering therapeutic gas into the gas chamber, and headgear connected to the patient's head for securing the respiratory mask to the patient's head. In use the cushion contacts and seals against the face of a patient whose mouth and/or nose is located within the gas chamber.

For patients with OSA or COPD, it is often desirable to wear the respirator for an extended period of time, and therefore the respirator is as comfortable as possible and the seal is as robust as possible. If the patient feels the mask is worn too tightly, comfort is inadequate, and treatment may be denied particularly if the patient's face experiences pinch marks, erythema, or even ulceration due to contact stresses that exceed the limits sustained by the face. If the mask is worn too loosely, this may result in an inadequate seal, may cause gas leakage, and thus a pressure below the therapeutic value that may cause the therapy to fail, and the leaked gas flow may also impinge on the patient's face, especially at the sensitive bridge of the nose or corners of the eyes, causing discomfort. Therefore, the wearing contact stress of the mask is very important to the comfort of the patient, the sealing is better effective under the contact stress as small as possible, one important influencing factor is the fit degree of the face of the patient and the cushion, and when the face of the patient is well attached to the cushion, the sealing can be ensured to be stable only by the small contact stress. However, in the existing breathing mask, the cushion is fixedly connected to the frame and is designed symmetrically, but in fact, the human face is not absolutely symmetrical, and the left face and the right face of each person have differences in different degrees (refer to the differences shown in fig. 11 and 12), and in some use scenes, such as side sleeping, the facial muscles on one side are squeezed and deformed to increase the left-right asymmetry, so that single-side air leakage is caused, and a large contact stress is needed to ensure that the sealing is effective.
