Nursing mask for respiratory medicine for automatically controlling oxygen inhalation concentration

Abstract

The invention discloses a nursing mask for respiratory medicine for automatically controlling oxygen inhalation concentration, and relates to the technical field of medical treatment. The nursing maskcomprises a mask main body, wherein a nose mask is fixedly connected inside the mask main body, an exhalation air pipe is communicated with the nose mask, the other end of the exhalation air pipe penetrates through the mask main body and extends to outside of the mask main body, a first one-way valve is arranged in the exhalation air pipe, an inhalation air pipe is communicated with the nose mask, and the other end of the inhalation air pipe is communicated with an inner space of the mask main body. According to the nursing mask, oxygen concentration of gas in the mask main body can be automatically controlled and adjusted through the cooperation among an air pipeline, an oxygen gas pipeline, an electromagnetic valve, an oxygen concentration sensor and a main control box, the nose mask isarranged in the mask main body, and is matched with the exhalation air pipe, the first one-way valve, the inhalation air pipe and a second one-way valve, so that repeated inhalation of exhaled gas containing a large amount of carbon dioxide by a patient can be avoided.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a nursing mask for respiratory medicine that automatically controls the concentration of oxygen inhalation. Background technique [0002] Nursing masks for respiratory medicine, also known as oxygen masks, are equipment that transfer oxygen from storage tanks to human lungs. Medical oxygen masks usually include ordinary masks, masks with storage bags, and Venturi masks, but they are used to support patients. Oxygen concentration should also be monitored in real time to avoid the low oxygen concentration making it difficult for the patient to breathe, which will not achieve the effect of support. If the oxygen concentration is too high, the patient will be drunk or oxygen poisoned. [0003] Traditional oxygen masks generally need to manually set the oxygen concentration in the mask in advance, and the lack of real-time monitoring and adjustment of the oxygen concentration in the ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a nursing mask for respiratory medicine that automatically controls the concentration of oxygen inhalation, which can automatically control and adjust the oxygen concentration of the gas in the main body of the mask, and at the same time prevent the patient from repeatedly inhaling the exhaled gas containing a large amount of carbon dioxide, so as to solve the traditional The oxygen mask lacks real-time monitoring and adjustment of the oxygen concentration in the patient's inhaled gas when the patient is breathing, which may easily lead to potential safety hazards
