Patent number: 10881819Abstract: The present invention relates to a mask and an inflatable structure thereof. The inflatable structure which is provided in a mask's body comprises: a ventilation seat; a sleeving connection which is sleeved at one end of the ventilation seat and sandwiches the mask's body together with the ventilation seat, with the sleeving connection provided with a socket tube so that the mask's body, the ventilation seat and the socket tube are in air communication; an air-sealed hood which is connected to the sleeving connection and provided around the socket tube. By virtue of the structure in the present invention, the air flow can be effectively imported into the patient to significantly increase the survival rate of the patient.Type: GrantFiled: April 8, 2016Date of Patent: January 5, 2021Assignee: Center Healthcare Technology Co., Ltd.Inventors: Yung-Chu Cheng, Chien-Feng Cheng, Yu-Liang Cheng
