Background

When venous blood, particularly venous blood of lower limbs, returns to the heart, the gravity needs to be overcome, the venous blood cannot return to the heart through the contraction of the heart, and the venous blood can return to the heart because the inner wall of a venous blood vessel is provided with a one-way valve, so that the blood can only flow towards the direction of the heart and the blood in the blood vessel is conveyed to the heart by matching with the contraction of muscles around the venous blood vessel. After the patient lies in bed for a long time, the exercise amount of the lower limbs is reduced, the venous blood backflow is not smooth, and venous thrombosis is easy to form. The lower limb venous pump acts on veins and muscles of the lower limb by utilizing air pressure to passively contract the veins and the muscles so as to promote venous blood backflow, reduce lower limb swelling and prevent lower limb venous thrombosis. In order to facilitate putting on and taking off, the air bag pressurizing belt of the existing lower limb venous pump is designed into a side-opening structure, a bandage or a zipper is installed on the side wall of an opening, when the air bag pressurizing belt is used, the bandage or the zipper is opened, the air bag pressurizing belt is wrapped on the leg of a patient, then the zipper is pulled or the bandage is tied, and the air bag is inflated and pressurized by a main machine to promote venous blood backflow. However, the binding band or the zipper for binding is only arranged at the opening of the side wall of the air bag, when the air bag is bound on a human body, the air bag is used as a bridge for connecting two ends of the binding band to bear certain stretching force, when the binding is loose, the stretching force is small, the air bag is not attached to the human body, and because the legs of the human body have physiological curves and the difference of different human bodies is large, the air bag pressurizing belt with the barrel-shaped structure cannot be closely attached to the human body after being fixed by the zipper or the binding band, usually, the air bag pressurizing belt is very tight at the calf and the thigh, and the ankle, the knee and the like are loose, so that a certain gap exists; if the air bag is tightly bound, the air bag is difficult to bear the tensile force on two sides and is easy to tear, and an excessive compression area is easy to form at the calf and thigh, so that the air flow in the air bag is influenced, and even the blood pressure circulation is hindered to influence the physiotherapy effect; in addition, the binding of the binding bands is complicated, a plurality of binding bands are bound in sequence and the tightness of the binding bands are adjusted by repeating the same action for a plurality of times, the operation time is long, and the tightness degree is not easy to control; the zipper is easily broken by the tension of the airbag due to weak pulling force, and the tightness cannot be adjusted. The common lower limb venous pump only has one working mode, is relatively poor in comfort and limited in application range. In clinical practice, an air bag pressurizing belt which can adjust the tightness of different parts in advance is needed, and the air bag pressurizing belt can adapt to concave-convex curves of different parts of a human body after being quickly bound.

The fixing strip 2 and the limiting rod 3 are made of relatively hard materials, such as stainless steel, aluminum alloy, carbon fiber or hard plastic and the like. The sheet-shaped fixing strip 2 has certain elasticity and enough strength, and can support the edge of the lining cloth 1 to keep the lining cloth 1 straight when being connected with the lining cloth 1 by sewing or rivets. The hook 4 and the fixing strip 2 are made of the same material, and can be of an integrated structure or a split assembly type structure to be connected with the fixing strip 2. When in use, the length of the binding belt 5 is adjusted according to the body shape characteristics of a patient, then the side, provided with the air bag, of the lining cloth 1 faces the skin of the patient, after the lining cloth 1 and the air bag are wrapped on the leg of the patient, the limiting rod 3 is clamped on the hook 4, the limiting rod 3 and the fixing strip 2 are overlapped, and at the moment, the air bag pressurizing belt is prepared; the air bag pressurizing belt is connected with a main machine of the lower limb venous pump, and the main machine of the lower limb venous pump is opened to inflate and pressurize the air bag to promote venous blood backflow.

1. Unidirectional mode. In the first stage, under the condition that the first exhaust valve 15 and the second exhaust valve 16 are both closed, the air pump inflates the near-end air chamber 12, the air is uniformly distributed into the strip-shaped inflation pipeline 11 through the near-end air chamber 12, near-to-far pressure pulses are formed in the strip-shaped inflation pipeline 11, and the air is finally concentrated into the far-end air chamber 13 until the far-end air chamber 13 is full of air; and in the second stage, the air pump is closed, the first exhaust valve 15 is kept closed, the second exhaust valve 16 is opened, the air is exhausted through the second exhaust valve 16, the air in the strip-shaped air inflation pipeline 11 is exhausted through the far-end air chamber 13 and the second exhaust valve 16, and pressure relief pulses from far to near are formed in the strip-shaped air inflation pipeline 11. The actions of the first stage and the second stage are repeatedly executed to generate the inflating and pressurizing actions from near to far so as to promote the venous blood pressure of the lower limbs of the human body to flow back to the heart.

2. A bidirectional mode. The first stage is the same as the unidirectional mode; and in the second stage, the air pump is closed, the second exhaust valve 16 is kept closed, the first exhaust valve 15 is opened, air is exhausted through the first exhaust valve 15, air in the strip-shaped air inflation pipeline 11 is exhausted through the near-end air chamber 12 and the first exhaust valve 15, and pressure relief pulses from the near to the far are formed in the strip-shaped air inflation pipeline 11. The repeated execution of the first and second phases can promote the venous blood pressure of the lower limbs of the human body to flow back to the heart.

3. A hybrid mode. The unidirectional mode and the bidirectional mode are alternately performed.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described above, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
