Abstract

The invention discloses a humidifier and a continuous positive-pressure ventilation therapy machine. The humidifier comprises an outer shell and a sealing ring. The outer shell comprises a first outer shell body, a second outer shell body and a buckling assembly. The second outer shell body and the first outer shell body are buckled through the buckling assembly. A floating sealing groove is formed between the first outer shell body and the second outer shell body. The sealing ring is arranged in the outer shell and comprises an elastic fork-shaped structure arranged at the edge of the sealing ring. The elastic fork-shaped structure is located in the floating sealing groove. When the first outer shell body and the second outer shell body are buckled, the floating sealing groove and the elastic fork-shaped structure is compressed, the elastic fork-shaped structure generates elastic force for expanding the floating sealing groove, and the sealing ring is matched with the buckling assembly to seal the buckled position. By means of the humidifier and the continuous positive-pressure ventilation therapy machine, the sealing reliability of the humidifier is improved.

Description

technical field [0001] The invention belongs to the technical field of ventilation treatment equipment, and in particular relates to a design of a sealing structure of a humidifier. Background technique [0002] Continuous positive airway pressure therapy machine is an important medical equipment in modern medicine, mainly used in the treatment of continuous positive airway pressure ventilation for various respiratory diseases or sleep-disordered breathing; it can assist in controlling and adjusting the breathing action of patients to help The patient resumes normal breathing. When the patient has symptoms such as respiratory failure, the continuous positive pressure ventilation therapy machine can prompt the patient to re-establish spontaneous breathing. Because some patients need to use it for a long time, or use the CPAP therapy machine in an uncertain environment, but due to the influence of environmental factors, the gas pumped by the CPAP therapy machine may be relati...
