Preferably, the airbag string comprises a plurality of large airbags 5 and a plurality of small airbags 4 which are arranged in sequence from the air inlet side to the air outlet side.

Furthermore, the one-way pressure valve 6 at the junction of the large air bag 5 and the small air bag 4 corresponds to the joint part of the limb.

Further, the limb joint part is a lower limb knee joint, that is, the limb brake auxiliary pneumatic pad is a lower limb brake auxiliary starting pad.

Furthermore, the number of the large air bags 5 is 2, and the number of the small air bags 4 is two.

Preferably, the base pad 8 is rectangular, and has a length of 1m and a width of 30 cm.

Further, the airbag stack 3 is parallel to the direction of the length.

Preferably, the delivery gas line 2 passes through the airbag stack 3 and is sealingly connected to the airbag stack 3.

The utility model has the beneficial effects that:

1) the operation is convenient and fast: the product does not need complicated connection process, only needs to help the patient to place the braking limb on the bottom pad, and is especially suitable for lower limbs, so that the knee joint is positioned at the junction of the large and small air bags.

2) And (3) environmental protection: can be used repeatedly: the product is non-consumable, can be used repeatedly, and can reduce the use cost of consumable materials.

3) Personalization: the gas volume in the gas bag sleeve of the product can be adjusted according to the leg thickness of the patient, and is customized.

4) It is foldable, convenient for storage: the product can be stored in a folding way after being sterilized after being exhausted by the air bag, and is convenient to store.

5) The comfort is good: the product can remarkably improve the numbness and discomfort of lower limbs of patients during braking, and can be popularized to patients lying in bed for a long time.

Drawings

Fig. 1 is a schematic structural view of a limb brake assist pneumatic pad of the present invention.

In the figure, 1, a miniature air pump; 2. a delivery gas conduit; 3. an air bag stack; 4. a small air bag; 5. a large air bag; 6. a one-way pressure valve; 7. an air inlet; 8 bottom cushion.

Detailed Description

The utility model is further described with reference to the following figures and specific examples.

Referring to fig. 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 and the like.

The length of the base pad is about 1 meter, the width is about 30cm, 2 groups of symmetrical air bag sets 3 are distributed on the base pad, and each air bag set 3 is provided with an air inlet; two small air bags and two big air bags, the air bags are connected by a one-way pressure valve 6.

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

With continued reference to FIG. 1, a pair of airbag assemblies 3 are elongated and secured to the base cushion 8 in a parallel or substantially parallel arrangement, the airbag assemblies 3 having gas inlets 7 into which gas may be injected; the air bag string is arranged in the air bag set 3 and comprises a plurality of air bags which are connected in series one by one through one-way pressure valves 6; two ends of the air bag string are communicated through an air conveying pipeline 2 to form an air conveying loop, and a micro air pump 1 for providing conveying air power is arranged on the air conveying pipeline 2.

In this embodiment, the one-way pressure valve 6 at the junction of the large air bag 5 and the small air bag 4 corresponds to a limb joint part, preferably a lower limb knee joint, i.e. the limb brake auxiliary pneumatic pad is a lower limb brake auxiliary starting pad.

In this embodiment, the base pad 8 has a rectangular shape with a length of 1m and a width of 30 cm.

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

In this embodiment, the delivery gas conduit 2 passes through the airbag stack 3 and is sealingly connected to the airbag stack 3.

When in use, the braking lower limbs are placed between the two groups of air bag sets, so that the knee joint is positioned at the junction of the large air bag and the small air bag. Then, the air is inflated from the air inlet 7 of the air bag set, the air bag set wall touches the skin of the braking lower limb as a boundary, and the air inlet is closed. And then the large air bag 5 is inflated, the large air bag 5 is inflated by the miniature air pump 1, air can be sequentially filled into the small air bag 4 from the large air bag 5 gradually due to the action of the one-way pressure valve, when the air enters the next air bag, the air in the previous air bag is emptied in a proper manner, and a massage effect is formed by automatically braking two sides of the lower limbs from the far end to the near end gradually through the air bags and deflating. Can improve blood circulation of lower limb, and prevent deep venous thrombosis.
