Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-4, a lower limb prosthesis capable of improving wearing comfort comprises a receiving cavity 1, a sealing ring silica gel sleeve 2 matched with the receiving cavity 1 is arranged in the receiving cavity 1, a plurality of groups of air vents 3 distributed in an annular array are arranged in the side wall of the sealing ring silica gel sleeve 2, all the air vents 3 are located at the top of a sealing ring of the sealing ring silica gel sleeve 2, a group of air bags 4 are arranged between the sealing ring silica gel sleeve 2 and the inner wall of the receiving cavity 1, the outer sides of the air bags 4 are fixedly connected with the inner wall of the receiving cavity 1, an exhaust valve 5 and an inflation valve 6 are arranged on the outer side of the receiving cavity 1, and the exhaust valve 5 and the inflation valve 6 penetrate through the side wall of the receiving cavity 1 and are communicated with the air bags 4.

The scheme has the following working processes:

when the artificial limb is worn, the sealing ring silica gel sleeve 2 is firstly required to be attached to a limb to be worn on a leg, then the limb with the sealing ring silica gel sleeve 2 is inserted into the receiving cavity 1 to enable the sealing ring silica gel sleeve 2 to be matched and fixed with the receiving cavity 1, the above process is consistent with the existing artificial limb wearing steps, however, at the moment, the air bag 4 is in an uninflated state, so that a gap still exists between the receiving cavity 1 and the sealing ring silica gel sleeve 2, at the moment, air flow can enter the receiving cavity 1 and is in skin contact with the air holes 3, the ventilation effect can be realized, the air bag 4 can be inflated after the micro air pump is externally connected with the inflation valve 6, the space between the receiving cavity 1 and the sealing ring silica gel sleeve 2 can be filled after the air bag 4 is inflated, the air bag 4 can simultaneously press the side walls of the sealing ring silica gel sleeve 2 and the receiving cavity 1 to improve the relative stability of the sealing ring silica gel sleeve 2 and the receiving cavity 1, in the actual wearing process, the air bag 4 can be exhausted in the artificial limb in the moving state to ensure the stability of the inflatable artificial limb.

According to the working process, the following steps are known:

this artificial limb can adjust the state of gasbag 4 according to human motion state, under the prerequisite of ensureing to dress stability, provides ventilative space through the shrink of gasbag 4, or can further promote through the inflation of gasbag 4 and dress stability, and the wearing comfort level of this artificial limb of lower limb has been synthesized in the improvement above.

Further, the interior of every group of bleeder vent 3 all includes that a plurality of is the bleeder vent 3 that linear array distributes along the straight line of sealing washer silica gel cover 2 vertical side, and evenly distributed's bleeder vent 3 can further promote the radiating effect.

Further, including three being linear array gasbag 4 in vertical direction in the group of a set of gasbag 4, the radial dimension of three gasbag 4 is all inconsistent and matches with the radial dimension that the position department corresponds respectively with the accepting cavity 1, the gasbag 4 that lies in intermediate position department in the three gasbag 4 communicates with two remaining gasbags 4 respectively through a plurality of communicating pipe 8 that are annular array and distribute, can promote the degree of adaptability of gasbag 4 and accepting cavity 1 inner chamber size when guaranteeing the binding face of the back large tracts of land of inflation through the cooperation of three gasbag 4.

Furthermore, the exhaust valve 5 and the inflation valve 6 are distributed in bilateral symmetry, so that the gravity balance of the artificial limb can be improved.

Furthermore, the exhaust valve 5 and the inflation valve 6 are respectively communicated with the air bag 4 at the middle position through an air pipe 7, the air bag 4 at the middle position can be ventilated in two directions while the other two air bags 4 are ventilated, and efficient exhaust and inflation are facilitated.

Further, discharge valve 5 is including installation cover 9, installation cover 9 runs through the lateral wall of accepting chamber 1 and communicates with trachea 7, one side fixedly connected with rubber circle 10 of accepting chamber 1 is kept away from to installation cover 9, it is connected with sealed post 11 to close soon through the screw thread in the installation cover 9, sealed post 11 keeps away from one side fixedly connected with swivel handle 12 of installation cover 9 and the outer wall of swivel handle 12 through rough treatment, during the exhaust, rotatory dismantlement down swivel handle 12 with sealed post 11 connect the whole that forms can, the simple operation is funny.

The foregoing shows and describes the basic principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that all the embodiments and descriptions are provided in the present invention, and that various changes and modifications can be made without departing from the spirit and scope of the present invention, and all such changes and modifications fall within the scope of the present invention as claimed.
