Description

Technical Field

[0001] The invention relates to the technical field of ventilator masks, and in particular to a non-invasive ventilator mask. Background Art

[0002] Non-invasive ventilator is a respiratory support method that does not require the establishment of an artificial airway. It mainly provides assisted breathing for users through masks, nasal masks, etc. For patients with breathing difficulties, non-invasive ventilator can reduce the work of respiratory muscles, relieve respiratory muscle fatigue, help users increase alveolar ventilation, and improve the efficiency of oxygen and carbon dioxide exchange. It is mainly suitable for patients with acute exacerbation of chronic obstructive pulmonary disease (COPD), acute respiratory failure, and those who may need non-invasive ventilator support after thoracic and abdominal surgery.

[0003] Among them, the non-invasive breathing mask is an important component of the non-invasive ventilator. It is in direct contact with the patient's face and is used to deliver the airflow generated by the non-invasive ventilator. The non-invasive breathing mask usually only reserves an air inlet connected to the non-invasive ventilator pipeline for the patient's breathing. However, some patients, such as those who cannot eat orally and need to supplement food nutrition with a gastric tube in the intensive care unit (ICU), also need to breathe with the help of a non-invasive ventilator. The existing non-invasive breathing masks cannot meet the needs of such patients. For this reason, the present application proposes a non-invasive ventilator mask that can meet the needs of wearing a gastric tube and using a non-invasive ventilator to breathe. Summary of the invention

[0004] The embodiment of the present application provides a non-invasive breathing mask. By opening a mounting through hole on the mask body, a gastric tube can be pulled out from the mask body, which can meet the needs of patients who wear a gastric tube and need to use a non-invasive breathing machine to breathe, thereby improving the practicality of the non-invasive breathing mask.

[0005] The embodiment of the present application provides a non-invasive ventilator mask, including a mask body, a pad fixedly connected to the rear end surface of the mask body, which is a silicone pad used to place the mask body on the patient's face; a through hole is provided in the middle of the front end surface of the mask body, and an air inlet pipe is fixedly connected therein, which is used to connect to the air outlet pipe of the non-invasive ventilator; an exhaust hole is also provided on the front end surface of the mask body, which is located on the upper side of the through hole and is used for the patient's exhalation;

[0006] The cover body is also provided with two mounting through holes, which are respectively located on the left and right sides of the front end surface of the cover body; the mounting through holes are located below the through holes and are used for inserting a gastric tube so that the gastric tube can be pulled out from the cover body.

[0007] Furthermore, an elastic material is glued and fixed to the inner wall of the installation through hole.

[0008] Further elastic materials may include soft silicone, soft plastic, etc.

[0009] Further, the inner diameter of the mounting through hole is set to between 5-6 mm.

[0010] Further, installation notches are reserved on the left and right sides of the pad for installing the restraining belt to fix the mask body on the patient's face.

[0011] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages: when providing non-invasive breathing to a patient with a gastric tube inserted, when the mask is worn on the patient's face, the patient's gastric tube is first inserted into the outside of the mask through the installation through hole, and then the mask is fixed to the patient's face through the restraint belt, and the air inlet is connected to the non-invasive ventilator to provide breathing for the patient. By opening the installation through hole on the mask, the gastric tube can be pulled out from the mask, which can meet the needs of patients who wear a gastric tube and need to use a non-invasive ventilator to breathe, thereby improving the practicality of the non-invasive breathing mask.
