Description of drawings

FIG. 1 is a schematic structural diagram of the limb braking auxiliary pneumatic pad of the present invention.

In the figure, 1. Micro air pump; 2. Air delivery pipeline; 3. Airbag set; 4. Small airbag; 5. Large airbag; 6. One-way pressure valve; 7. Air inlet; 8. Bottom pad.

Detailed ways

The present utility model will be further described below with reference to the accompanying drawings and specific embodiments.

Referring to Figure 1, the auxiliary pneumatic cushion is composed of a micro air pump 1, a conveying air pipeline 2, an air bag set 3, a small air bag 4, a large air bag 5, a one-way pressure valve 6, an air inlet 7 of the air bag set, a bottom cushion 8, etc. .

The length of the bottom cushion is about 1 meter and the width is about 30 centimeters. There are two sets of symmetrical airbag sets 3 distributed on it. Each airbag set 3 contains an air inlet; two small airbags and two large airbags. One-way pressure valve 6 is connected.

The small air bag 4, the one-way pressure valve 6, and the large air bag 5 form the air bag string.

Continuing to refer to FIG. 1 , a pair of the airbag sets 3 are elongated and fixed on the bottom pad 8 in parallel or substantially parallel, and the airbag sets 3 have an air inlet 7 into which gas can be flushed; the The airbag string is arranged in the airbag set 3, and includes a plurality of airbags connected in series by one-way pressure valves 6; 2 is provided with a micro-air pump 1 for providing pneumatic power for conveying.

In this embodiment, the one-way pressure valve 6 at the junction of the large airbag 5 and the small airbag 4 corresponds to the joint of the limb, and the joint of the limb is preferably the knee joint of the lower limb, that is, the limb brake assist Pneumatic pads are lower extremity brake assist start pads.

In this embodiment, the bottom pad 8 is rectangular, with a length of 1 m and a width of 30 cm.

In this embodiment, the airbag assembly 3 is parallel to the direction of the length.

In this embodiment, the gas delivery pipeline 2 passes through the airbag set 3 and is sealedly connected with the airbag set 3 .

When in use, the lower limbs are placed in the middle of the two sets of airbag sets, so that the knee joint is located at the junction of the large and small airbags. Then, inflate from the air inlet 7 of the airbag set, and the inflation target is that the wall of the airbag set touches the skin of the lower limb of the brake as the boundary, and the air inlet is closed. Then, the large airbag 5 is inflated, and the large airbag 5 is inflated by the micro air pump 1. Due to the action of the one-way pressure valve, the air can only be gradually filled from the large airbag 5 to the small airbag 4 in sequence. When the air enters the next airbag, The air in the previous air bag is evacuated according to the situation, forming a massage effect formed by the air bag inflating and deflating gradually from the distal end to the proximal end on both sides of the self-braking lower limbs at the same time. It can improve the blood circulation of immobilized lower extremities and prevent the formation of deep vein thrombosis.

The above are the preferred embodiments of the present utility model, and those of ordinary skill in the art can also carry out various transformations or improvements on this basis. Without departing from the general concept of the present utility model, these transformations or improvements should belong to the present utility model. within the scope of the new claims.
