Multifunctional non-invasive ventilator mask

Abstract

The invention discloses a multifunctional noninvasive ventilator mask, comprising a mask body (4), an intake port (8), an exhaust tube (9), a mask ring (3), a silicone ring (17), a gastric tube port (10) and an oxygen suction tube port (15).The edge of the silicone ring (17) is provided with a silicone ring edge (1) having T-shaped or Y-shaped cross section, and the surface of the silicone ring edge (1) is provided with a gauze layer (20) that can be filled with cotton and the like to well adapt to the face of a patient, thus reducing air leakage and reducing pressure sores greatly.Compared with the prior art, the multifunctional noninvasive ventilator mask is fully fitting with the specific facial form of the patient, comfort is improved, facial pressure sores and eye, nasal and oral symptoms such as dryness in the patient due to wearing of the mask can be solved, patient compliance is improved, and workload of a nurse can be reduced effectively.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a multifunctional non-invasive respirator mask. Background technique [0002] Non-invasive positive pressure ventilation is mainly connected to the man-machine interface through nasal or oral and nasal masks to treat mild to moderate respiratory failure. At present, in clinical work, there are many problems in the use of non-invasive ventilator masks, such as: The contact surface of the ventilator is made of silicone sheet. Patients who have used the non-invasive ventilator for a long time may cause pressure sores due to long-term pressure on the bridge of the nose and the skin on both sides of the nose, which may cause local blood circulation disorders and cause pressure sores. The inability to fit well will increase the air leakage of the ventilator mask, resulting in symptoms such as dryness, itching, and pain in the patient's eyes. It can stimulate the mucous membrane of the...

Problems solved by technology

[0002] Non-invasive positive pressure ventilation is mainly connected to the human-machine interface through nasal or oral-nasal masks to treat mild to moderate respiratory failure. At present, in clinical work, there are many problems in the use of non-invasive ventilator masks, such as: The contact surface of the ventilator is made of silicone sheet. Patients who have used the non-invasive ventilator for a long time may cause pressure sores due to long-term pressure on the bridge of the nose and the skin on both sides of the nose, which may cause local blood circulation disorders and cause pressure sores. The inability to fit well will increase the air leakage of the ventilator mask, resulting in symptoms such as dryness, itching, and pain in the patient's eyes. It can stimulate the mucous membrane of the upper respiratory tract, leading to symptoms such as dryness and astringency in the patient's nasal cavity and mouth. The above conditions will reduce the patient's compliance and treatment effect. For patients with carbon dioxide retention and respiratory failure, it is not possible to increase the leakage of the mask and reduce PaCo2 according to the condition. For example, when using a non-invasive ventilator, the patient drinks water when thirsty. In order to prevent aspiration, it is usually necessary to remove the mask. During nebulization inhalation and sputum suction, the use of the mask must also be stopped. Such repeated operations such as removing and wearing the mask increase the workload of the nurses. 1. The specifications of the oxygen inhalation tubes are not uniform, resulting in large air leakage holes in the mask and increased air leakage, which affects the treatment effect. big trouble
