Problems solved by technology

Since the oxygen provided by the oxygen supply source and the carbon dioxide exhaled by the patient will both flow through the gas delivery unit, the carbon dioxide exhaled by the patient will be affected by the oxygen provided by the oxygen supply source, resulting in the gas measured by the carbon dioxide sensor being mixed. gas, so it is impossible to measure carbon dioxide effectively and accurately

Abstract

The invention relates to an air delivery pipe of a breathing mask and the breathing mask. The air delivery pipe of the breathing mask is suitable to be connected with a carbon dioxide measurement device; the air delivery pipe comprises a first pipe casting, a second pipe casting and a check valve; the first pipe casting comprises a shell; the shell defines a bottom end, a top end, an air holding chamber positioned between the bottom end and the top end, an air exhaust hole which is positioned between the bottom end and the top end and used for communicating the air holding chamber and the external part, and a through hole which is positioned between the bottom end and the top end and used for communicating the air holding chamber and the carbon dioxide measurement device; the top end is provided with an opening so that the air holding chamber is communicated with the external part; the second pipe casting is inserted into the air holding chamber of the shell and comprises an air inletpositioned at the bottom end of the shell, and an air outlet extruded out of the top end of the shell; the check valve is arranged on the shell and used for closing the air exhaust hole; and the check valve can be opened so that air in the air holding chamber can be exhausted from the air exhaust hole. By the air delivery pipe, a carbon dioxide concentration value of air exhaled by a patient can be measured accurately.

Description

technical field [0001] The invention relates to an air delivery tube of a breathing mask and the breathing mask, in particular to an air delivery tube of the breathing mask and the breathing mask which can separate a gas channel for transmitting oxygen and a gas channel for transmitting carbon dioxide exhaled by a patient. Background technique [0002] As disclosed in U.S. Patent No. 7,004,168, the mask assembly includes a mask, a gas delivery part assembled at the bottom of the mask, and an oxygen delivery tube assembled at the bottom of the gas delivery part. The oxygen delivery tube is used for supplying oxygen The oxygen source is connected with each other, and the oxygen provided by the oxygen supply source is sequentially delivered to the patient's mouth and nose through the oxygen delivery tube, the gas delivery part and the mask for inhalation by the patient. [0003] In this patent, it is disclosed that a carbon dioxide sensor for sensing carbon dioxide can be insta...
