Problems solved by technology

[0003] However, the applicant has found in actual investigations that in actual use of this existing oxygen mask, the wearer often has a feeling that the oxygen flow directly hits the mouth and nose area, and some sensitive wearers will have a relatively tight mouth and nose area. Obvious airflow compression discomfort, nasal dryness and even headaches, which reduce the comfort of oxygen masks to a certain extent
At present, in order to reduce this airflow pressure, medical staff usually reduce the oxygen flow rate according to the wearer's feedback, but this will also reduce the oxygen concentration, which will affect the effect of oxygen therapy to a certain extent
In addition, the applicant found in actual research that the existing oxygen mask would cause repeated inhalation of carbon dioxide in actual use, which directly reduces the oxygen inhalation effect

Abstract

The invention relates to the technical field of oxygen masks, and discloses an oxygen mask body and an oxygen mask. In the oxygen mask body, the air outlet end of an oxygen guide cylinder is connected to a mouth-nose area and communicated with a breathing cavity, and the edge of a cylinder opening of the air outlet end is lower than or flush with the inner surface of a mask wall of the mouth-nose area in the whole circle direction; and the volume of the oxygen guide cylinder is 2000mm < 3 > to 16000mm < 3 >. The oxygen mask body can still ensure effective and stable oxygen uptake concentration when the respiratory rate and the oxygen flow rate of a wearer change, and can also remarkably reduce the airflow oppression of oxygen, so that the oxygen can be uniformly diffused to the mouth, the nose and the surrounding area of the wearer; therefore, the oxygen uptake treatment effect is ensured, and the use comfort of a wearer is improved.

Description

technical field [0001] The present invention relates to the technical field of oxygen masks, in particular to an oxygen mask body and an oxygen mask. Background technique [0002] The existing oxygen mask usually includes a mask body, an oxygen connector is provided on the mask body, and the oxygen connector is used to connect an oxygen delivery tube, wherein the inner surface of the breathing cavity in the mask body has an oxygen guide tube extending into the breathing cavity, An oxygen inlet channel is arranged in the oxygen connector, one end of the oxygen inlet channel is communicated with the oxygen delivery pipe and the other end is communicated with the oxygen guide cylinder. In this way, when in use, oxygen can enter into the breathing chamber sequentially through the oxygen delivery tube, the oxygen inlet channel in the oxygen connector and the oxygen guide tube in the breathing chamber for use by the wearer. [0003] However, the applicant's research in practice f...
