Intelligent cold-warm constant temperature receiving cavity for artificial limb

Technical Field

The utility model relates to an artificial limb (artificial limb) socket, in particular to an artificial limb (artificial limb) intelligent cold and warm constant temperature socket, which belongs to the intelligent technical field of rehabilitation engineering.

Background

In recent years, with the development of modern medical rehabilitation engineering science and technology, a great number of amputees caused by various diseases, cancers, vascular diseases, trauma, traffic accidents and the like have made higher demands on the assembly of artificial limbs (also called artificial limbs). Prostheses are very important as aids for the rehabilitation of amputees or incomplete stumps to replace artificial limbs that have lost part of the function of the limb, restoring the patient to a certain self-care and working capacity. The receiving cavity is used as the most important component of the artificial limb, is directly contacted with the residual limb to accommodate the residual limb, and plays roles of bearing weight, controlling the motion of the artificial limb and the like. Whether the socket structure fits the residual limb will directly affect the performance of the function of the prosthesis and the wearing comfort of the patient. The lower limb receiving cavity of the artificial limb (artificial limb) exists at present; the plug-in type receiving cavity, the overall contact receiving cavity, the suction type receiving cavity and the like are divided according to parts; the ankle disconnection receiving cavity, the calf receiving cavity, the knee disconnection receiving cavity, the thigh receiving cavity, the hip disconnection receiving cavity and the artificial limb of the upper limb (artificial limb) are divided into parts; a wrist off-off receiving cavity, a forearm receiving cavity, an elbow off-off receiving cavity, an upper arm receiving cavity, a shoulder off-off receiving cavity and a scapular thoracic cavity receiving cavity; wherein, the shank receiving cavity is of the type; 1. a traditional artificial leg receiving cavity 2, a ligament bearing receiving cavity, a PTB (percutaneous transluminal bungs) receiving cavity, a PTS (partial transshipment) receiving cavity, a KBM (KBM) receiving cavity, a 3 and TSB (total contact sorption type) receiving cavity, and a 4 and PTK (percutaneous transshipment) receiving cavity. The thigh receiving cavity is of a type; 1. an insertion type thigh receiving cavity, a traditional insertion type receiving cavity and an insertion type full-contact type receiving cavity; 2. a suction type accepting cavity, namely a CAT-CAM ischial containing accepting cavity, an ischial bearing accepting cavity, a Flexible (Flexible) accepting cavity quadrilateral accepting cavity, an ISNY accepting cavity and a CAT/CAM accepting cavity; double-layer socket UDS socket. Applying a silica gel sleeve and a gel sleeve; ALPS gel sheath, silica gel sheath, staffine alder silica gel sheath, alpha gel sheath, silica gel sheath, Ossur silica gel sheath, Baotaiou silica gel sheath, etc.; the silica gel sleeve and the gel sleeve have the advantages of protecting the stump, avoiding the friction between the stump and the receiving cavity, having superior suspension performance, being comfortable and beautiful to wear, improving the walking capability and the like.

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.
