Description

Oxygen mask for preventing carbon dioxide retention

Technical Field

The utility model belongs to the field of medical equipment, concretely relates to prevent oxygen mask of carbon dioxide retention.

Background

At present, in each ward of a hospital, patients often need to use a mask to inhale oxygen to quickly improve hypoxemia due to severe hypoxemia, and the functional damage of important organs and tissues caused by overlong hypoxia time is prevented. In clinical practice, patients sometimes inhale oxygen through a nasal catheter when hypoxemia occurs, and the hypoxemia of the patients can not be relieved at all, so that oxygen inhalation through a mask is needed to rapidly improve oxygen saturation. At present, the common oxygen mask clinically used is often incapable of discharging carbon dioxide smoothly due to too small air outlet holes and easy to feel suffocated due to unsmooth expiration of a patient, so that the patient is reluctant to use the mask to inhale oxygen, the improvement of hypoxemia of the patient is influenced, or the retention of the carbon dioxide of the patient is aggravated because the gas exhaled by the patient cannot be discharged smoothly. To change the condition, the nurse often needs to inhale oxygen through the nasal catheter after carbon dioxide retention is found, so that the patient needs to change between the mask and the nasal catheter, which increases the workload of the nurse. In addition, the common mask has the air outlet hole which is only 1cm, so that patients feel suffocating when using the mask, and the compliance of the patients is poor.
