Technical Field
The invention belongs to the field of medical care instruments, and particularly relates to an instrument for preventing deep venous thrombosis of lower limbs.
The invention also relates to a using method of the device for preventing deep venous thrombosis of the lower limbs.
Background
The deep vein of the lower limb is a main passage vessel for conveying blood of the lower limb to return to the heart, when the blood in the deep vein system is coagulated and forms thrombus due to various reasons, the blood of the lower limb cannot smoothly return to the heart, a large amount of blood stays in the lower limb, the venous pressure is increased, and the extravasation of blood components occurs, so that limb swelling and pain are caused, and the diseases become deep vein thrombosis of the lower limb. To enhance circulation of blood in the lower extremities, compressive forces need to be applied across the lower extremities (including the legs and/or feet) to squeeze the veins of the legs.
For this reason, pneumatic compression devices for preventing the occurrence of the above-mentioned illness have been reported, which simply compress the entire foot, lower leg or thigh. For patients who are immobilized and do not move regularly (such as in an intensive care unit), prolonged bed rest can lead to disuse atrophy of leg muscles, in addition to deep venous thrombosis of the lower limbs.
Application publication No. CN108433935A reports a sports apparatus for preventing deep vein thrombosis of lower limbs, which has the functions of swinging feet left and right and reciprocating back and forth, realizing ankle pump movement, promoting blood circulation and flow of legs, effectively preventing deep vein thrombosis of legs and avoiding disuse atrophy of leg muscles. The sports apparatus is mainly formed by interconnecting a supporting piece and a left-right swing driving device, so that the structure is relatively complex.

Detailed Description
The invention is further described below with reference to the accompanying drawings. In the present specification, the directions of up, down, left, right, and the like are all directions shown in the drawings.
Referring to fig. 1, the basic framework of the present invention is: a connecting plate 1 made of plastic material is respectively connected with a foot rest 2 at the left and right ends, a leg rest 3 is integrally formed with the foot rest 2, and an angle theta is arranged between the foot rest 2 and the leg rest 3, and is an angle conforming to the foot and the leg of a human body. The left foot support and the right foot support (leg support) are connected into a whole by the connecting plate, so that movement between the two foot supports (leg supports) in actual use is avoided. Since the foot rests and the leg rests on the left and right sides of the connection plate have the same structure, only one side of the structure will be described below.
Four air bags 4, 5, 6 and 7 are arranged on one surface of the foot support 2 corresponding to the sole of the human body, and the four air bags enclose a hollow circle, which is called a foot air bag.
The leg support 3 is provided with a plurality of air bags 8, 9 and 10 (three are shown in fig. 1) corresponding to the legs of a human body, which are called leg air bags, the leg air bags are arranged side by side perpendicular to the air bags on the foot support, and each leg air bag 8, 9 and 10 is provided with a fixing belt 12 which can be a sticking buckle belt.
The foot air bags 4, 5, 6, 7 and the leg air bags 8, 9, 10 are provided with air holes 11, and the air holes 11 are respectively connected to a console 13 through inflation tubes. The control console 13 is internally provided with a singlechip, an air pump and a storage battery which are connected with the singlechip, and a display screen, a control key and a charging interface which are connected with the internal singlechip are arranged on the table top of the control console 13. The control console 13 controls the air pump to alternately inflate all the air bags respectively. The console is a well-known technology, and will not be described in detail herein.
When the foot bag is specifically used, the human foot part stretches into a hollow part (part B in fig. 2) formed by the four air bags 4, 5, 6 and 7 of the foot air bag, the four air bags are wrapped by the four air bags 4, 5, 6 and 7, and the four air bags are respectively arranged on the outer side of the foot, the instep, 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 by the fixing belts 12.
The air holes 11 of the foot air bags 4, 5, 6, 7 and the leg air bags 8, 9, 10 are connected to an air pump of a console 13 through air pipes, and the console periodically or circularly compresses air to the foot air bags and the leg air bags at predetermined time intervals.
When the air bags 4 positioned at the outer side of the foot are controlled by the air pump of the console to start to be inflated, the rest 3 air bags of the foot are in an airless state, the air bags 4 at the outer side of the foot compress the foot to swing rightwards (leftwards) to form an inversion action, then the console is inflated to the air bags 6 positioned at the inner side of the foot, and simultaneously the air bags 4 at the outer side of the foot are deflated to compress the foot to swing leftwards (rightwards) to form an inversion action, so that the operations of the inversion and the inversion of the foot are circularly carried out; similarly, the air pump of the console controls the air bags 5 on the instep and the air bags 7 on the sole of the foot alternately to perform the same operation, and compresses the foot to swing upward and downward, respectively, so as to perform the dorsiflexion and plantarflexion operations of the foot cyclically.
When the foot air bags perform inflation and deflation actions, the control console controls the inflation and deflation of the leg air bags, the sequence of the inflation and the deflation of the leg air bags starts from the leg air bags 8 arranged at the tail ends of the leg supports and sequentially inflates the leg air bags 9 and 10, and the deflation starts from the leg air bags 8 arranged at the tail ends of the leg supports and sequentially deflates the leg air bags 9 and 10.
The device for preventing deep venous thrombosis of lower limbs disclosed by the invention has the following advantages:
1. the air pump circularly charges and deflates the air bag, so that the air bag can be continuously expanded and contracted, the massage effect is achieved, and the use is very convenient.
2. When in operation, the control console can automatically operate by inputting the data such as the inflation sequence, the time, the air pressure and the like of each air bag.
3. Simple structure avoids adopting too much mechanical structure, and the preparation is easy, even the gasbag damages to some extent, it is also very convenient to change.
