technical field

The utility model relates to a protective sticker, in particular to a protective sticker for head and face special-shaped pressure sores used for a non-invasive ventilator mask, and belongs to the field of medical auxiliary equipment.

Background technique

For some patients with respiratory failure, non-invasive ventilator is a convenient, fast, effective and non-invasive means of respiratory support. However, in the actual clinical application of the non-invasive ventilator, for some patients who need long-term support and high oxygen concentration requirements, especially for patients with thin faces, when the non-invasive ventilator mask is in close contact with the skin in the dangerous triangle of the face , both sides of the alar of the nose, the bridge of the nose, both cheekbones and the mandible are pressure points. If the non-invasive ventilator mask is used for a long time, the pressured local skin is prone to erythema and damage, and then medical device-related pressure sores appear on the skin in the dangerous triangle of the face; when the contact is loose, it will leak air, resulting in a decrease in the minute ventilation of the patient. Low. And patient comfort is low, and compliance is poor. How to effectively prevent the occurrence of pressure sores in the dangerous triangle area of the face and the skin of the root of the auricle when using the above-mentioned medical-related devices is the key to improving patient comfort and compliance.

Patent No. CN103920218A applied for a non-invasive ventilator patient's facial triangular protective film and its design method. On the basis of the conventional square exudate absorption film, two and a half oval orbital contours A, a nasal contour B and a It is formed by the outline C of the bridge of the nose and consists of forehead stickers, nasal root stickers, and cheek stickers, which can avoid direct contact between the patient's face and the mask, but there are also shortcomings. First, its design is not based on the anatomical shape of the human face. Therefore, its The obtained protective film cannot protect comprehensively, which will cause the mask to have a poor seal with the face during use, and the resulting air leakage of the ventilator will directly cause the patient to die due to the inability to receive the continuous support of the ventilator to assist exhalation. There is an increased risk of exacerbations, which can even lead to life-threatening patient respiratory distress. Secondly, the square exudate-absorbing film needs to be wasted every time it is used, and the subtracted part cannot be used, resulting in waste of resources and increasing medical waste. Moreover, as the patient's facial muscles drive the micro-movement of the mask, the existing defects are also reflected in the protection When the film and the skin are fixed, the mechanical effect cannot be evenly distributed. When the patient actively breathes, the physiological fluctuations of the facial muscles during breathing will cause the protective sticker to shift. In the case of the protective sticker shifting, The intended effect of preventing pressure sores is then lost. Furthermore, the major defect of manual cutting is not that it cannot be standardized industrial production. Secondly, the disadvantage of using manual cutting is that the operation of scissors on pre-sterilized products will cause secondary pollution. , requiring a ventilator to maintain life, the immune function of the body and patients with low immunity are independent high risk factors for fatal infection.
