Above-describedly be arranged on the gas check on the blister cavities and lower floor's blister cavities layer outside the side, can constitute by airway and self-closing's valve.Self-closing's valve act as guiding inflation, aerofluxus, fine setting tolerance, and the gas in overpressure protection.
What be connected use with gas check is self-filler.The self-filler structure is as follows: battery is electrically connected to micromachine, the miniature inflator pump of minitype motor driving; Miniature inflator pump is connected with self-closing's valve pipeline; On airway, be provided with pressure transducer; Described pressure transducer is electrically connected with relay, and relay is received on the micromachine.Self-filler has real-time compensating roller function simultaneously, regulates the receptive cavity degree of tightness by regulating airbag gas content.
This self-filler compact conformation, in light weight, the part assembling is simple, can be installed in artificial limb with respect to the bottom of receptive cavity or the calf of artificial limb.
The inner liner of this utility model " two blister cavities " design had both improved the comfort level of dress greatly, had avoided the problem built on the sand of artificial limb dress again.Blister cavities with gas regulation can allow the deformed limb of girth of a garment variation can adapt with prosthetic socket all the time, but the elasticity of amputation patient's regulated at will deformed limb and receptive cavity, the convenient wearing, the trouble and the high expense of exempting frequent replacing receptive cavity.And this utility model can effectively solve problems such as friction, sweat, tenderness, and cost of manufacture is lower.
