A prosthetic receiving chamber is a lumen-like part of a prosthetic limb that accommodates the amputee's stump. It is a connecting part between the stump and the prosthesis, and has the function of bearing weight and suspending the prosthesis.
The prosthesis receiving chamber generally has ABS resin, PP sheet and carbon fiber three kinds of materials. Among them, ABS resin is acrylonitrile-butadiene-styrene copolymer, is a general purpose resin, after modification (adding additives or alloy and other methods) to improve the performance of ABS is an engineering plastic, ABS alloy production, variety, wide application, is the main modified plastic. ABS is a light yellow granular or beaded opaque resin, non-toxic, tasteless, low water absorption, with good comprehensive physical and mechanical properties, such as excellent electrical properties, wear resistance, dimensional stability, chemical resistance and surface gloss, and easy to process and form. PP plate is a kind of semi-crystalline material. It is harder than PE and has a higher melting point. Used in acid and alkali resistant equipment, environmental protection equipment, waste water, waste gas discharge equipment, washing tower, clean room, semiconductor factory and related industrial equipment, is also the preferred material for the manufacture of plastic water tank, of which PP thick plate is widely used in stamping plate, punching plate and so on. Pure PP board: low density, easy welding and processing, with superior chemical resistance, heat resistance and impact resistance, non-toxic, tasteless is currently one of the most environmentally friendly engineering plastics. The main color is white, computer color, other colors can also be customized according to customer requirements. Glass fiber reinforced PP board (FRPP board) : After 20% glass fiber reinforced, in addition to maintaining the original excellent performance, strength, rigidity, etc. are doubled compared with PP, and has good heat resistance, low temperature impact, corrosion resistance and arc resistance, low shrinkage. Especially suitable for chemical fiber, chlor-alkali, petroleum, dyes, pesticides, food, medicine, light industry, metallurgy, sewage treatment and other fields. Carbon fiber plate is the carbon fiber arranged in the same direction by resin infiltration and hardening to form carbon fiber plate, can effectively solve the problem of multi-layer carbon fiber distribution work difficulties and large quantities of engineering, reinforcing effect is good, convenient construction.
Using high-quality carbon fiber raw materials and good basic resin, carbon fiber sheet has high tensile strength, corrosion resistance, shock resistance, impact resistance and other good properties.
The receiving chamber is an important part of the prosthesis, it plays the role of force transmission and control of the prosthesis movement. Functional prosthesis receptions must simultaneously have wearing comfort, force transmission and control. In addition, The acceptance chamber is the most important and critical part of the prosthesis, which connects the stump and the prosthesis. The success of the acceptance chamber will affect the function of the whole prosthesis.
