Recently, Dalian Barrier-free Construction Promotion Association, together with the Municipal Procuratorate, the Municipal Disabled Persons' Federation and the Municipal Deaf Association, formed a special research group to conduct field research in the 120 emergency center of the city. During the survey, all parties focused on the communication dilemma faced by deaf people in emergency medical assistance-because deaf people can't call for help through traditional telephone calls, they put forward suggestions to build a visual emergency channel through WeChat applet.

The 120 Emergency Center of the city quickly responded to this special appeal, listed solving the "urgent difficulties and anxiety" of the deaf group as a key task, and efficiently started the information barrier-free system transformation project. After intensive development and debugging, the newly upgraded "Dalian First Aid Convenience Service" applet has been officially launched. Citizens only need to enter "Dalian 120" in the WeChat search bar to enter the small program interface. The platform innovatively sets up three intelligent calling modules: "One-click calling for help" provides conventional quick response; "Video call for help" supports synchronous communication of graphics, texts and videos; The special function of "Hearing Impaired Call for Help" is specially added, and the text input channel is specially customized for the deaf group to ensure zero barriers to communication in emergencies. This functional upgrade not only fills the information communication gap in the urban first aid system, but also highlights the humanistic temperature of Dalian's precise care for the needs of special groups and technological empowerment in the process of building an all-age-friendly city.
