Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment after knee joint surgery, in particular to a compression leg sleeve with a pressure gradient for joint replacement surgery. Background Art

[0002] Joint replacement refers to the use of metal, high-molecular polyethylene, ceramics and other materials to make artificial joint prostheses based on the shape, structure and function of human joints. They are implanted into the human body through surgical techniques to replace the function of diseased joints, thereby relieving joint pain and restoring joint function. Knee replacement and hip replacement are the two most common types of joint replacement surgeries.

[0003] After knee replacement surgery, patients are less active due to pain and psychological effects. Furthermore, the risk of venous thrombosis (VLT) in the lower limbs is higher due to factors such as surgery, tourniquets, the use of bone cement, and advanced age, which lead to blood stasis, venous endothelial damage, and hypercoagulability. Intermittent pneumatic pressure pumps (IPCs) are currently a common physical therapy device for preventing VLT. As a supplementary treatment device, they have limited usage time and therapeutic effects.

[0004] Therefore, the research and development of a postoperative compression leg sleeve with a pressure gradient for joint replacement surgery that can effectively promote venous blood return in the limbs, facilitate blood circulation and wound healing, reduce postoperative edema, simulate the physiological gradient pressure of the human lower limbs, and effectively prevent deep vein thrombosis in the lower limbs is an urgent problem to be solved at this stage. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model provides a compression leg sleeve with a pressure gradient for joint replacement surgery. The sleeve utilizes a plurality of air cavities distributed along a first direction on the belt body, and the air pressure values of the plurality of air cavities change gradiently along the first direction. The sleeve can apply a gradient pressure simulating the physiological state of the human lower limbs to the veins of the limbs, thereby accelerating the flow rate of venous blood, promoting venous blood return, facilitating blood circulation and wound healing, reducing postoperative edema, and preventing venous thrombosis. The sleeve has a simple structure and is easy to use.

[0025] In order to facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0026] Please refer to Figure 1 and Figure 2, which is an embodiment of a leg sleeve with pressure gradient for joint replacement surgery provided by the present invention, comprising a belt body 1, the belt body 1 having two oppositely arranged first side edges 11, both of which extend along a first direction; a matching connecting component 3 is provided on the two first side edges 11, the connecting component 3 can connect the two first side edges 11 to form a sleeve body, a receiving cavity is formed inside the sleeve body, the shape of the receiving cavity matches the shape of the human leg, and the belt body 1 can be wrapped around and positioned on the human leg through the connecting component 3; the belt body 1 has a plurality of air cavities 2 distributed along the first direction and independent of each other; the air pressure values in the plurality of air cavities 2 are The air cavity 2, whose pressure value changes gradiently as it rises or falls along the first direction, can apply a gradient pressure that conforms to physiological laws to the veins of the limbs, gradually pressurizing the limbs to form a gradient pressure similar to that of a physiology, thereby ensuring that venous blood flows to the heart rather than back to the soles of the feet or superficial veins, accelerating the venous blood flow rate, promoting venous return, and facilitating blood circulation and wound healing in the limbs, which is of great significance for preventing deep vein thrombosis; an observation hole 12 is provided in the middle of the belt body 1, which is connected to the accommodating cavity. The position of the observation hole 12 corresponds to the joint replacement position of the patient's limb. The blood circulation can be conveniently observed through the observation hole 12, and the belt body 1 is prevented from blocking the wound and causing pressure sores.

[0027] It should be noted that the present invention reduces the cross-sectional area of blood vessels, increases the venous blood flow velocity, and at the same time reduces the venous volume and increases the venous return (flow); the present invention can reverse venous hypertension, improve the pump function of skeletal muscles, promote venous return, improve lymphatic drainage, and reduce postoperative edema of the affected limb; the present invention can improve the function of venous valves and avoid venous reflux caused by incomplete closure of venous valves.

[0028] It should be noted that the first direction is preferably set to the length direction of the human leg to ensure that the belt body 1 can be conveniently wrapped around the human leg.

[0029] It should be noted that the belt body 1 is preferably made of a composite fabric with good fit to ensure that the belt body 1 can be firmly wrapped around the human leg.

[0030] In this embodiment, please refer to Figure 1 and Figure 2There are six air cavities 2, and the positions of the six air cavities 2 correspond to the ankle, lower calf, upper calf, knee joint, distal thigh, and proximal thigh of the human leg in sequence. The air pressure values in the six air cavities 2 decrease gradually from bottom to top along the human leg. The six air cavities 2 form a pressure gradient that conforms to physiological laws on the patient's leg along the direction from the ankle to the thigh. The pressure is maximum at the ankle, and gradually decreases along the direction of the calf, knee joint, and thigh, thereby promoting the venous blood of the patient's leg to flow to the heart and avoiding the tourniquet effect caused by applying equal pressure to the entire lower limb. In other embodiments, the number of air cavities 2 can also be set to other values, based on the ability to effectively promote the venous return of the patient's leg.

[0031] Specifically, the air pressure values in the six air cavities 2 are preferably set to 24 mmHg, 18 mmHg, 14 mmHg, 11 mmHg, 10 mmHg, and 8 mmHg in sequence from bottom to top of the human leg; in other embodiments, the air pressure values in the six air cavities 2 can also be adjusted according to actual conditions to ensure effective return of venous blood in the patient's legs.

[0034] For clarification, please refer to Figure 1 and Figure 2 , notches are provided on the two first side edges 11 of the belt body 1. When the two first side edges 11 are connected, the two notches can be spliced to form an observation hole 12; after knee replacement surgery, the observation hole 12 should be located at the knee of the human leg to facilitate observation of blood circulation and the specific condition of the drainage tube, to avoid distortion and pressure of the drainage tube, and to prevent the belt body 1 from touching the incision and causing pressure sores.

[0035] In this embodiment, please refer to Figure 1 and Figure 2Each air cavity 2 should be provided with an inflation tube 21 connected thereto, and an air valve 22 is provided between the air cavity 2 and the inflation tube 21. The air pressure pump can make each air cavity 2 reach a specific air pressure through the inflation tube 21; the air valve 22 is preferably set as a one-way valve, which can facilitate inflation and ensure the stability of the air pressure in the air cavity 2; further, the inflation tubes 21 of the air cavity 2 are all connected to a main pipeline, and the air pressure pump can inflate all the air cavities 2 at the same time through the main pipeline. As the air pressure value in the air cavity 2 increases, the air valve 22 of each air cavity 2 can be closed in turn; in other embodiments, the inflation tube 21 connected to each air cavity 2 is independently provided, and the air pressure pump is connected to each inflation tube 21 to inflate each air cavity 2 in turn.
