Take the suction type receiving cavity thigh as an example to introduce the correct dressing method:
I. wearing method:
1. The amputee sits in a chair (or stands) and applies talcum powder or prickly heat powder to the stump.
2. Cover the residual limb with smooth and thin silk or cover the residual limb with long residual limb. Note that the cloth and sock cover should be flat without wrinkles. The upper edge should cover the thigh root and the back should be covered with ischial tubercle.
3. Remove the negative pressure valve on the receiving chamber.
4. Put the distal end of the cloth or sock sock into the receiving chamber.
5. Put the distal end of the cloth or sock cover through the hole of the load valve.
6. Insert the residual limb into the receiving cavity.
7, stand up, the prosthesis straight, one hand to pressure the prosthesis to avoid joint bending, the other hand to the outside, pull out of the bag cloth. When pulling wrap cloth outward, should notice skin to feel, want to feel the bag bla of which side around stump limb is insufficient, can pull hard DORA a few. In addition, if the knee joint of the healthy leg can do some flexion and extension when pulling the cloth, the residual limb can be moved up and down by the piston in the receiving cavity (that is, the residual limb can move up and down), then it is easier to fully pull the residual limb into the receiving cavity.
8. After pulling out the cloth, the tightness around the upper edge of the acceptance cavity of the residual limb skin can be adjusted appropriately, and then the negative pressure valve can be installed.
2. How to determine whether the position of residual limb penetrating the acceptance cavity is correct?
1. Standing position, when the body weight is transferred to the prosthesis side, the ischial tubercle can feel good bearing capacity; Subpubic and adductor parts did not hurt; The skin at the end of the residual limb felt to have touched the base of the receiving cavity without pain; The outer rotation Angle of the prosthetic foot in walking is similar to that of the healthy foot.
2. If the ischial tubercle is not load-bearing after wearing, the skin at the end of the residual limb cannot touch the lumen base; However, the crotch position (the upper edge of the acceptance cavity) in the root of the residual leg shows a large skin fold, which may indicate that the soft tissue of the residual leg fails to be pulled into the acceptance cavity and is not fully penetrated, so the prosthesis needs to be removed and re-worn.
3. If the prosthesis is worn, it is found that the crotch position of the residual limb is uncomfortable during standing and walking, and the toe of the prosthesis rotates outward or inward too much during walking, indicating that the prosthesis is not properly and slanted, and it needs to be removed and re-worn. When re-wearing, attention should be paid to making the direction of the inner wall of the receiving cavity consistent with the walking direction of the amputee.
