Problems solved by technology

[0002] At present, the main equipment for non-invasive ventilation in China includes a dedicated non-invasive ventilation ventilator and corresponding nasal masks and nasal masks, and the price is relatively expensive; in addition, both the nasal mask and the mask need to be fixed on the patient's face, otherwise it will leak air and affect the ventilation effect , the comfort of the patient is also very poor, often due to the patient's poor cooperation and intolerance, resulting in the failure of non-invasive ventilation

Embodiment

[0018] When in use, cover the head mask 3 on the head of the patient. If the patient has a stomach tube or a naso-intestinal tube, extend the stomach tube or naso-intestine tube to the outside of the head cover 3 through the active air hole 5, and use a 50ml injection needle to inject the gas through the airbag inflation port 8. The annular airbag 4 is inflated to ensure the best sealing state, and the air intake pipe is connected to the hood 3 through the air inlet 7, and non-invasive ventilation is started. During the ventilation process, the pressure gauge 1 is adjusted through the pressure gauge adjustment button 2 according to the treatment needs. , to maintain the stability of the pressure in the hood, the leak valve 6 constantly performs gas exchange during the ventilation process to avoid carbon dioxide retention.

Abstract

The invention discloses a noninvasive ventilation hood, which comprises a pressure gauge, a hood and an annular air bag, wherein the hood is connected with the annular air bag and is provided with the pressure gauge, movable air holes, a leak valve and an air inlet; the annular air bag is provided with an air bag charging port; the pressure gauge is provided with a pressure gauge adjusting button. According to the noninvasive ventilation hood, in a ventilation process, the annular air bag can be used for effectively fixing the hood, so that the comfort of a patient can be improved, and the skin of the patient is prevented from being injured by a fixing band of the conventional nose mask; positive end-expiratory pressure is set by adjusting the pressure of the pressure gauge to keep the pulmonary alveolus of the patient in a functional state; meanwhile, the circulation of gas in the hook can be ensured by the leak valve, so that carbon dioxide accumulation is avoided for the patient; the noninvasive ventilation hood is easy to operate and is convenient to use, and the comfort of the patient can be improved while ventilation is ensured.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a convenient, practical and safe non-invasive ventilation head mask. Background technique [0002] At present, the main equipment for non-invasive ventilation in China includes a dedicated non-invasive ventilation ventilator and corresponding nasal masks and nasal masks, and the price is relatively expensive; in addition, both the nasal mask and the mask need to be fixed on the patient's face, otherwise it will leak air and affect the ventilation effect , The patient's comfort is also very poor, often due to the patient's poor cooperation and intolerance, resulting in the failure of non-invasive ventilation. Contents of the invention [0003] To sum up, the object of the present invention is to provide a non-invasive ventilation hood. [0004] The purpose of the present invention is achieved by the following technologies: [0005] A non-invasive ventilation hood, com...
