Background

In recent years, a plurality of amputees caused by various diseases, cancers, vascular diseases, trauma, traffic accidents and the like have higher requirements for assembling artificial limbs (also called artificial limbs) with the development of modern medical rehabilitation engineering science and technology, the artificial limbs are used for compensating amputees or incomplete limb stumps to replace artificial limbs losing partial functions of limbs, and an auxiliary tool for enabling patients to recover certain self-care and working capacity is very important, the receiving cavity is used as the most important component of the artificial limb, the artificial limb is directly contacted with the stump to contain the stump and play a role in bearing and controlling the movement of the artificial limb, whether the receiving cavity structure is suitable for the stump or not and the wearing comfort level of the patient, the lower limb receiving cavity of the current artificial limb (artificial limb) has an inserting type receiving cavity, a full contact type receiving cavity, a suction type receiving cavity and the suction type receiving cavity, the ankle type receiving cavity, the calf receiving cavity, the knee type receiving cavity, the thigh type receiving cavity, the hip type receiving cavity, the ischiadic type receiving cavity, the ankle type receiving cavity, the ankle type receiving type, the ankle.

The residual limb in the receiving cavity is the real victim along with the change of the external temperature, the muscular movement of the residual limb in the use of the artificial limb and the change of the skin body temperature. The skin condition of the skin under different temperature conditions is different. The principle of expansion with heat and contraction with cold should be no strange, and pores follow the same physical principle.

1. When the patient is in cold weather, the artificial limb feels very uncomfortable due to the cold receiving cavity when the artificial limb is worn. In the process of wearing and using the artificial limb (artificial limb), muscle contraction, reduction of blood circulation and synovial secretion and poor compliance of tissues around joints (including muscles, ligaments and the like) are caused by cold, so that many people feel complications such as muscular soreness, joint stiffness, arthritis pain and the like. When the stump in the closed receiving cavity is stimulated by low temperature and humidity, blood vessels on the body surface can be spasticized, the blood flow is reduced, tissue ischemia and hypoxia are caused, cell damage is caused, particularly the part with poor blood circulation at the far end of the stump, and the comfort level of the receiving cavity and the use function of the artificial limb are further influenced.

2. When the patient is hot, the pores are enlarged, and substances are easily secreted and water is easily lost when the patient wears the receiving cavity. The skin of the stump is in a sealed cavity stressed by negative pressure, and is easy to generate complications such as eczema, blisters, cysts, tinea alba, dermatitis, discoloration of the stump, edema and the like. Because the outside air temperature is high, and the disabled limb can cause muscle contraction, blood circulation and synovial fluid secretion increase during movement, the receiving cavity is in a damp and hot state, if the receiving cavity is not clean, various bacteria and mould can be easily and rapidly propagated in a large quantity, skin infection and various skin tinea can be easily caused, and the smell of the receiving cavity is unpleasant. The phenomenon that the residual limb slides down and the residual limb rubs with the piston of the receiving cavity due to muscle atrophy after soft tissue perspiration can also occur, skin damage occurs, the receiving cavity is used to aggravate the injury under the condition that the wound is not healed, and the condition after infection is very serious.
