Description

An anti-indentation ventilator mask

technical field

The utility model relates to a mask, in particular to an anti-indentation respirator mask.

Background technique

The ventilator can temporarily help the patient breathe and complete the oxygen exchange of the lungs when the patient's respiratory muscles are fatigued or the patient is unable to breathe normally.

When the ventilator is in use, the mask is the link between the patient and the ventilator, and the airtightness and comfort of the mask are directly related to the therapeutic effect. There are two main problems that often occur in the actual use of the mask, one is air leakage at the edge of the mask; the other is that the edge of the mask causes pressure on the facial skin. Air leakage will make the pressure in the mask less than the predetermined pressure and affect the therapeutic effect, so it is very important to eliminate air leakage. Usually, in order to eliminate air leakage, the headband is often tightened. However, tightening the headband may not completely eliminate the problem of air leakage on the one hand. Indentation, redness and even breakouts of the skin.

In the prior art, in order to solve the problem of air leakage of the ventilator mask and avoid indentation on the patient's face, the medical staff will fill the pad between the mask and the face with a soft dressing, such as silicone viscose foam dressing. However, on the one hand, when the face moves, these dressings are prone to dislocation and cause air leakage; on the other hand, dressings with better performance, such as silicone viscose foam dressings, are more expensive, and the use of dressings will increase the economic burden of patients; Otherwise, the dressing will produce indentations after long-term use. When the mask is removed and used again, it must be fitted with the indentations, otherwise air leakage will easily occur. In addition, for medical staff, before applying the dressing, the medical staff needs to cut the dressing according to the size of the mask, which increases the clinical workload; for the user, putting the dressing on the face increases the discomfort of wearing the mask; from the dressing On its own, when the dressing is removed and reapplied, it is much less sticky and prone to misplacement.

Therefore, still need to develop a kind of new respirator mask.
