Hello: My mother installed it in Wuxi Jiangnan Prosthetic Center.

Hello, young Junko! I feel sorry for what happened to you. According to my experience in the industry, this is definitely a quality problem, but there is no domestic standard for silicone sleeves, so there is no better way to help you. Silicone socket is usually used for diabetic amputation, but some companies use it for marketing. Some companies even say that computer mold taking or UDS socket (the English name of double-layer socket) is an immature technology. Your situation should belong to the question of acceptance. You can cancel the service and claim compensation according to the requirements of the national standard. At the same time, pay attention to see if the company has the assembly qualification of the civil affairs department.
