Description

A device for preventing deep vein thrombosis of lower extremities

technical field

The utility model belongs to the field of medical care equipment, in particular to a device for preventing deep vein thrombosis of lower limbs.

Background technique

The deep veins of the lower extremities are the main access vessels responsible for transporting the blood of the lower extremities back to the heart. When the blood in the deep venous system coagulates and forms thrombus for various reasons, the blood of the lower extremities cannot return to the heart smoothly, and a large amount of blood stays in the lower extremities. The pressure increases and extravasation of blood components occurs, resulting in swelling and pain in the extremities. This type of disease is known as deep vein thrombosis of the lower extremities. In order to enhance blood circulation in the lower extremities, it is necessary to apply compressive force to squeeze the veins in the legs throughout the lower extremities (including the legs and/or feet).

For this reason, there have been reports of pneumatic compression devices for preventing the occurrence of the above-mentioned conditions, and these pneumatic compression devices simply squeeze the entire foot, calf or thigh. For patients who are immobile and unable to exercise regularly (such as in the intensive care unit), in addition to deep vein thrombosis of the lower extremities, prolonged bed rest can lead to disuse atrophy of leg muscles.

Application publication number CN108433935A reports an exercise device for preventing deep vein thrombosis of the lower extremities. It has the effect of swinging the foot from side to side and back and forth, realizing ankle pump movement, promoting blood circulation in the legs, and effectively preventing deep vein thrombosis in the legs. Form and avoid disuse atrophy of leg muscles. Since the exerciser is mainly composed of supporting parts and left and right swing driving devices connected to each other, its structure is relatively complicated.

Description of the logo in the figure

1 connecting plate, 2 foot drags, 3 leg support, 4, 5, 6, 7 foot airbags, 8, 9, 10 leg airbags, 11 air holes, 12 fixing straps, 13 console.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described. It should be noted that the up, down, left, right, etc. mentioned in this manual are all based on the direction shown in the illustration.

Please refer to shown in Fig. 1, the basic framework of the present utility model is: a connecting plate 1 of plastic material, its left and right ends respectively connect a foot support 2 respectively, and what is integrally formed with the foot support 2 is provided with a leg support 3, the foot support An angle θ is provided between 2 and the leg rest 3, and this angle is the angle that conforms to the human body's feet and legs. The left and right foot rests (leg rests) are connected as one by the connecting plate, so as to avoid movement between the two foot rests (leg rests) in actual use. Since the foot rests on the left and right sides of the connecting plate have the same structure as the leg rests, only the structure on one side will be described below.

Foot support 2 is provided with four airbags 4, 5, 6 and 7 on one side corresponding to the sole of the human body, and these four airbags form a hollow circle, which is called foot airbags.

Leg support 3 is provided with several airbags 8, 9 and 10 (three shown in Fig. 1) on one side corresponding to the human leg, which are called leg airbags, and the leg airbags are arranged side by side perpendicular to the airbags on the footrest. Each leg airbag 8,9,10 is provided with a fixing belt 12, and the fixing belt can adopt a hook and loop.

The foot airbags 4 , 5 , 6 , 7 and the leg airbags 8 , 9 , 10 are all provided with air holes 11 , and these air holes 11 are respectively connected to a console 13 through inflation tubes. The console 13 is provided with a single-chip microcomputer, an air pump and a storage battery connected to the single-chip microcomputer, and the console 13 is provided with a display screen connected to the internal single-chip microcomputer, a control button and a charging interface. The air pumps are controlled by the console 13 to inflate all the airbags in turn. The console is a relatively mature known technology, so it will not be described in detail here.

During concrete use, after the hollow part (part B among Fig. 2) that four airbags 4,5,6,7 of human foot stretch into foot airbag form, be surrounded by four airbags 4,5,6,7 Encased, the four airbags are respectively placed on the outer side of the foot, the dorsum of the foot, the inner side of the foot, and the sole of the foot. The legs of the human body are placed on the air bags 8, 9, 10 and fixed with the fixing belt 12.

The air holes 11 of the foot airbags 4, 5, 6, 7 and leg airbags 8, 9, 10 are connected to the air pump of the console 13 through the trachea, and the console compresses the air to the feet periodically or cyclically at predetermined time intervals. Airbags and airbags.

When the airbag 4 on the outer side of the foot is controlled by the air pump on the console and starts to inflate, the other three foot airbags are in an airless state, and the airbag 4 on the outer side of the foot is compressed and the foot swings to the right (left) to form an inward movement , then the console inflates the airbag 6 located on the inside of the foot, and at the same time deflates the airbag 4 on the outside of the foot, compresses the foot and swings to the left (right) to form a valgus action, so that the varus and valgus operations of the foot are cycled Same, the air pump of the console controls the air bag 5 positioned at the dorsum of the foot and the air bag 7 on the sole of the foot in the air bag of the foot in turn to perform the same operation, compressing the foot to swing upwards and downwards respectively, so that the dorsiflexion of the foot is carried out in a cycle and plantar flexion operations.

When the foot airbag is inflated and deflated, the leg airbag is controlled by the console to inflate and deflate. Sequentially inflates the leg airbags 9, 10, also starts from the leg airbag 8 placed at the end of the leg rest and deflates by the leg airbags 9, 10 during deflation.

The device for preventing deep vein thrombosis of lower extremities disclosed by the utility model has the following advantages:

1. The air bag is cyclically inflated and deflated by the air pump, so that the air bag is continuously inflated and contracted to achieve the effect of massage, and it is very convenient to use.

2. During operation, you only need to input data such as the order, time, and air pressure of each air bag inflated and deflated in the console to operate automatically.

3. The structure is simple, avoiding the use of too many mechanical structures, easy to manufacture, even if the airbag is damaged, it is very convenient to replace.
