Breathing mask

Abstract

The invention relates to a breathing mask which comprises a masking body, an air delivery pipe and a medium, wherein, the mask body comprises a breathing hole and an enclosing wall positioned on the rear side of the breathing hole, the enclosing wall defines a penetration hole communicated with the breathing hole, the air delivery pipe is arranged on the front side of the mask body and communicated with the breathing hole, the medium is installed in the penetration hole, and the medium is made of a material that can easily absorb heat and moisture. Since the medium is arranged on the inner side of the mask body and is close to the nose and mouth of a patient, heat and moisture in the wet and hot gas exhaled from the patient can be quickly and immediately absorbed and stored by the medium, so that the storage efficiency of heat and moisture can be improved. Moreover, since a large part of the wet and hot gas exhaled from the patient passes through the medium before being discharged from the air delivery pipe, the wet and hot gas exhaled from the patient can be prevented from condensing inside the mask body.

Description

technical field [0001] The invention relates to a breathing mask, in particular to a breathing mask with the function of exchanging moist heat gas. Background technique [0002] Continuous Positive Air Pressure (CPAP) ventilator is currently the most commonly used method to treat obstructive sleep apnea. Since the breathing mask of the ventilator is covered on the patient's face for a long time, the patient's exhaled hot and humid The gas tends to mist inside the respirator and condense on the respirator. [0003] In addition, because the ventilator provides the patient with positive pressure gas for a long time, the patient's airway will be dry and uncomfortable. Hot and humid gas on demand. In addition to the use of adding a humid heater, another way of use is as figure 1 and figure 2 As shown, an artificial nose 12 is installed on the breathing mask 11. The artificial nose 12 can also be called a heat and moisture exchange mixer HME (Heat and Moisture Exchanger), whi...

AI Technical Summary

Problems solved by technology

[0004] However, the above two methods cannot effectively solve the problem that the humid and hot gas exhaled by the patient produces mist in the breathing mask 11 and condenses on the breathing mask 11, and the use of a humid heater or artificial nose 12 will make the structure of the entire respiratory system more complicated

Furthermore, since the artificial nose 12 is arranged outside the breathing mask 11, the medium 123 is far away from the patient's mouth and cannot directly and quickly absorb and store the heat and moisture of the hot and humid gas exhaled by the patient.

[0005] This shows that above-mentioned existing breathing mask obviously still has inconvenience and defect in structure and use, and urgently needs to be further improved

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem
