Problems solved by technology

However, when AECOPD patients with hypercapnia use oxygen-driven aerosol inhalation, due to the elimination of hypoxemia, the respiratory rate and depth are reduced, and the alveolar minute ventilation is reduced, resulting in an increase in blood carbon dioxide levels and aggravating respiratory acidosis , reduce cough ability, is not conducive to the patient's clearance of airway secretions

Embodiment Construction

[0022] Please refer to figure 1 and figure 2 As shown, it shows the specific structure of the preferred embodiment of the present invention, including an oxygen-driven atomization mechanism 10 , a T-shaped joint 20 and a mouthpiece 30 .

[0023] Wherein, the oxygen-driven atomization mechanism 10 includes structures such as an atomization cup, a drug storage tank, a siphon, an oxygen inlet, and an atomization nozzle. When high-pressure oxygen flows out of the atomization nozzle through the oxygen inlet, a Negative pressure, the negative pressure sucks out the liquid in the drug storage pool through the siphon tube, and sprays it out with high-pressure oxygen to generate atomized gas. It is an existing mature technology. Here, the specific structure and work of the oxygen-driven atomization mechanism The principle is not described in detail.

[0024] The T-shaped joint 20 includes a first opening 21 , a second opening 22 and a third opening 23 , the first opening 21 communic...

Abstract

The invention discloses a device for bi-phase forming of exogenous positive end-expiratory pressure through oxygen driven inhalation. The device comprises an oxygen driven inhalation mechanism, a T-shaped joint and a mouthpiece, wherein an inspiration one-way valve is arranged in a first opening; and the mouthpiece is connected with a second opening of the T-shaped joint. Therefore, atomizing gas with inspiration oxygen helps dilute secretion of the air passage and improve the blood oxygen saturation, blood oxygen improvement facilitates improving expiratory dyspnea of patients and active cough to remove secretion of the air passage, and meanwhile, the exogenous positive end-expiratory pressure resists endogenous positive end-expiratory pressure of a COPD (Chronic Obstructive Pulmonary Disease) patient so as to be favorable for reducing the concentration of carbon dioxide in blood. Accordingly, not only is secretion of the air passage removed, but also carbon dioxide retention caused by oxygen inhalation is prevented.

Description

technical field [0001] The invention relates to the technology in the field of nebulizers, in particular to a device for driving nebulization with oxygen and forming exogenous positive end-expiratory pressure. Background technique [0002] Chronic Obstructive Pulmonary Disease (COPD) is a disease characterized by airflow limitation, mainly manifested as chronic cough, expectoration, acute exacerbation (AECOPD) cough exacerbation Increased sputum volume, coughing up yellow purulent sputum, dyspnea, and even hypoventilation, eventually leading to respiratory failure with hypoxemia and hypercapnia. Sputum can aggravate hypoventilation, so promoting expectoration is one of the main treatment measures for acute exacerbation of COPD. Nebulization inhalation is currently the main method to promote expectoration, and the most common method of nebulization is oxygen-driven nebulization. However, when AECOPD patients with hypercapnia use oxygen-driven aerosol inhalation, due to the ...
