Background technique

Non-invasive positive pressure ventilation is mainly connected to the human-machine interface through nasal or oronasal masks. During use, it has little impact on patients' daily life such as eating and speaking, and the patient's comfort is high. At the same time, it avoids various injuries and complications of the artificial airway, so it is easy to be accepted by patients. This method is widely used in respiratory failure caused by various reasons, such as chronic obstructive pulmonary disease, postoperative respiratory failure, acute left heart failure, etc. Since the contact surface between the mask and the nose and face has only two layers of thin silicone membranes, and there is no subcutaneous fat at the root of the nose, for patients who continue to use non-invasive ventilators, the skin on both sides of the bridge of the nose and the sides of the nose is under pressure for a long time, resulting in blood circulation disorders. pressure sores. Nasofacial pressure ulcers occur in 7% to 27% of patients during noninvasive positive pressure ventilation therapy. Once a pressure sore occurs, the comfort of the patient will decrease, which will directly lead to a decrease in the tolerance and compliance of the patient's ventilator treatment, and affect the treatment of the primary disease.

In the prior art, in order to avoid the occurrence of pressure sores and alleviate the pain of patients, clinically, O-shaped gauze pads, foam patches, transparent patches, Dressing pads composed of hydrocolloid dressings are placed on the nose and face to prevent pressure sores. Studies have shown that the above methods have certain effects in the prevention of pressure ulcers. However, the above-mentioned dressings need to fit the facial skin to play a good role. During use, patients often adjust the mask due to talking, drinking, local itching, etc., so that the position of the mask and the dressing is offset, resulting in the dressing covering the eyes and squeezing the dressing. The nostrils affect the ventilation effect, etc. To sum up, in the prior art, there is no convenient way to fix the position of the dressing to prevent the dressing from covering the eyes. Squeeze the nostrils to affect the ventilation effect and reduce the pressure on the patient's face from the edge of the mask.

In order to solve the above-mentioned technical problems, the non-invasive ventilator mask adopted by the utility model includes a cover, a pipeline interface, a headband and a dressing. One end of the cover is connected to the pipeline interface, and the cover body is provided with a headband buckle. The headband is connected to the cover through the headband buckle, the dressing is arranged on the edge of the cover, and also includes a card body, the card body is composed of a connecting flange, an embedded structure and a booster flange, and the embedded structure is located at the connecting Between the flange and the booster flange, the embedding structure is a wedge-shaped structure composed of two inclined surfaces. A fixing groove is provided at the joint between the dressing and the cover, and the wedge-shaped structure is embedded in the fixing groove. The connection The flange is attached to the dressing.

Further, the connecting flange of the card body is also provided with a peel-off strip.

Further, the connection between the two slopes of the embedded structure is arc-shaped.

Further, an airbag is also included, a groove is arranged on the edge of the cover, the airbag is arranged at the groove, and an air injection port is arranged on the airbag.

The beneficial effects of the utility model are: since the dressing is fixedly connected to the card body through the connecting flange of the card body, and the card body is provided with a wedge-shaped structure composed of two inclined surfaces, the embedded structure can be embedded in the pre-set place during use. in the fixing groove on the cover. Since the embedded structure is a wedge-shaped structure composed of two inclined surfaces, the wedge-shaped structure is gradually clamped by the fixed groove during the process of being embedded into the fixed groove, which plays a role in firmly fixing the card body, and because the dressing is fixedly connected with the card body Together, the dressing can be fixed on the non-invasive ventilator mask through the card body, preventing the dressing from moving during use by the patient. When it is necessary to remove and replace the dressing from the mask of the non-invasive ventilator, use your fingers to move the booster flange, and one inclined surface in the wedge-shaped structure will move closer to the other inclined surface. At this time, the contact between the embedded structure and the fixed groove is reduced, preventing the card from being stuck. The card body is stuck in the groove, and the card body can be taken out from the fixing groove more conveniently. When the card body is disassembled from the non-invasive respiratory mask, the lifting strip provided on the connecting flange can be pulled by hand, which can help the card body to be separated from the cover.
