technical field

The utility model relates to the technical field of oxygen masks, in particular to a multifunctional pressure sore prevention type oxygen fixed mask.

Background technique

Non-invasive ventilators have been widely used clinically for their convenience, no need for tracheal intubation or incision, fewer complications, intermittent use, shorter mechanical ventilation and hospitalization time, and less pain and nursing time for patients. However, patients who use oxygen fixed masks for a long time are prone to pressure sores on the local skin. Once a pressure sore occurs, it is not only prone to secondary infection, but also directly leads to a decrease in the patient's tolerance and compliance with ventilator therapy, affecting the treatment of the primary disease.

The main cause of pressure sores is that patients using non-invasive ventilators must wear oxygen fixed masks for a long time. In order to prevent air leakage, the masks need to be close to the skin, resulting in long-term pressure on the local skin. Once the external pressure exceeds the level of normal capillary pressure, Local circulation will be affected, dermal papillary layer capillary and venule congestion, lymphocyte infiltration, etc. will all be produced under long-term oppression, and thrombus will be formed at the same time, and bullae will be formed under the epidermis, causing the epidermis to fall off and form early ulcers; at the same time, when the patient's head If the head moves, it will cause the oxygen tube to shift or rotate, causing the mask to generate torque, and the force will be applied to the patient's face, which will cause facial discomfort.

Therefore, it is necessary to propose a multifunctional pressure sore prevention type oxygen fixed face mask to solve the above problems.
