Each step taken by the amputee will cause the prosthesis to be hit by a body weight, which will form a large load on the prosthesis. How to protect the prosthesis and extend the service life of the prosthesis? Keep the prosthetic socket dry and clean: if the prosthetic socket is in a state of humidity and heat for a long time while amputees wearing prosthetics. It will lead to the rapid proliferation of various bacteria, skin infections or various skin ringworm and other symptoms, and will also lead to odors in the socket. The inside of the prosthetic socket can be wiped off with a warm, wet towel wringing and then placed in a dry place to dry. It can also be simply scrubbed with warm water, the water temperature can not be too hot, to prevent the deformation of the prosthetic socket. Most of the prosthetic socket of traditional prosthetics are made of leather, and can be wiped off with a wet hand towel soaked in soapy water, just like the AK prosthetic socket. The prosthesis must be determined whether the inside of the prosthetic socket is dry before it is worn.  
You can prepare more residual socks with good sweat-absorbing performance for backup, which is convenient for cleaning and replacement when using.

In the process of using prosthetics, it is necessary to pay attention to whether there is an abnormal sound in the prosthesis, if there is an abnormal sound, it may be that some joint parts or joints are damaged or loose, and the prosthetic technician should be contacted in time for maintenance. If you are wearing the foam plastic sponge sleeve used on the outside of the thigh bone prosthesis, if a crack is found in front of the knee, which needs to be bonded or pasted with some reinforcement materials in time. This type of prosthesis is not suitable for wearing short waist socks, with elastic socks, this type of socks are prone to tearing the BK cover.
Do regularly inspected, repaired: generally after a year or a half year, you need to go to the prosthesis production agency to do a comprehensive inspection and maintenance of the prosthesis, which is to extend the service life of the prosthesis, prevent the stump long-term wearing of the prosthesis, because of improper use or abnormal prosthesis, it is possible to lead to various limb diseases.
