Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a device for preventing venous thromboembolism. Background Art

[0002] Venous thromboembolism is a disease caused by the formation of blood clots in the deep veins, which blocks blood flow, leading to thrombosis, venous obstruction and inflammatory response, and ultimately embolism. Sitting or standing for a long time: Sitting or standing for a long time can cause obstruction of blood return in the lower extremity veins, increasing the risk of blood clots forming in the deep veins. Trauma or surgery: After trauma or surgery, the body is traumatized, and the blood coagulation system is prone to abnormalities, leading to thrombosis. In addition, the need to stay in bed for a long time or have difficulty in moving may lead to poor blood circulation in the lower extremities, thereby increasing the risk of deep vein thrombosis. Therefore, for patients who are bedridden for a long time or have difficulty in moving, effective anticoagulant prevention measures need to be implemented for patients, which can not only reduce the incidence and mortality of venous thromboembolism, but also relieve patients' pain and reduce medical costs.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0025] Example:

[0026] Reference Figure 1-Figure 4 A venous thromboembolism preventer comprises a main support platform 1, an auxiliary support platform 2 is slidably connected to the main support platform 1, a limited position seat is arranged on the side wall of the main support platform 1, and a connecting seat is arranged on the side wall of the auxiliary support platform 2, and the connecting seat is slidably connected to the limited position seat through a connecting rod, please refer to Figure 1 As shown in , the connecting rods are symmetrically arranged in two groups.

[0027] The thigh of the patient can be placed on the main support platform 1, and the calf can be placed on the auxiliary support platform 2. An extension plate 6 is fixedly connected to the other side of the auxiliary support platform 2, and a pedal 7 is rotatably connected to the extension plate 6. A sponge pad or a foam pad is also provided in the pedal 7 for flexible contact with the position of the heel or the instep, and a connecting belt for fixing the corresponding instep can also be provided on the pedal 7 to fix and limit the position of the patient's leg. This is not described in the accompanying drawings, and the foot can be limited by winding and tightening a rope or installing a button belt. This is a prior art.

[0028] In addition, a front baffle 601 and a rear baffle 602 are respectively provided on the extension plate 6, and the pedal 7 is provided between the front baffle 601 and the rear baffle 602, and a return spring 603 is fixedly connected to the front baffle 601, and the other end of the return spring 603 is fixedly connected to the outer wall of the pedal 7, please refer to Figure 3 As shown in , when the pedal 7 needs to be used, the patient's foot can be placed on the sponge pad or foam pad inside the pedal 7, and then the connecting belt can be tightened. At this time, since the patient's foot is in a dorsiflexed state, the pedal 7 will rotate with the foot to adapt to the state of the foot.

[0029] In addition, a guide cylinder 3 is fixedly connected to one side of the auxiliary support platform 2, and a guide rod 301 is slidably connected to the guide cylinder 3. A piston is arranged at the bottom of the guide rod 301, and the piston fits against the inner wall of the guide cylinder 3. Then the top leg pad 4 is fixedly connected to the top of the guide rod 301. Here, the top leg pad 4 needs to be arranged between the main support platform 1 and the auxiliary support platform 2, and an electric push rod 201 is fixedly connected to the main support platform 1, and a mounting plate is arranged at the bottom of the auxiliary support platform 2. The output end of the electric push rod 201 is fixedly connected to the mounting plate, and a booster cylinder 5 is fixedly arranged at the bottom of the main support platform 1 through a connecting plate, a booster rod 501 is slidably connected to the booster cylinder 5, a piston is fixedly connected to one end of the booster rod 501, and the piston fits against the inner wall of the booster cylinder 5, and the other end of the booster rod 501 is fixedly connected to the mounting plate, and the booster cylinder 5 is connected to the guide cylinder 3 through a pipeline.

[0030] When the patient places his thigh and calf on the support platform of the device, the switch of the electric push rod 201 is started, and the electric push rod 201 will drive the auxiliary support platform 2 to move back and forth. When the auxiliary support platform 2 moves toward the main support platform 1, the patient's foot position will be tilted due to the influence of the pedal 7. At this time, the booster rod 501 follows the movement of the auxiliary support platform 2, and then pressurizes the gas in the booster cylinder 5 and transports it to the guide cylinder 3. At this time, the guide rod 301 in the guide cylinder 3 will drive the leg-supporting pad 4 to move upward, so that the leg-supporting pad 4 can contact the patient's leg, and then lift the patient's leg. At this time, the knee joint of the leg is lifted, and the angle between the thigh and the calf becomes smaller, so that the leg is bent, and the foot can use the pedal 7 for support, and the rear baffle 602 will limit the inclination angle of the pedal 7 to avoid damage to the ankle.

[0031] When the electric push rod 201 drives the auxiliary support platform 2 to reset, the top leg pad 4 under the leg returns to its position, and the patient's foot gradually becomes in a dorsal extension state. At the same time, the reset spring 603 can also limit the position of the pedal 7, so that the foot can be rotated while the leg is bent, which can help promote the return of blood in the foot veins. By reciprocatingly bending the patient's legs, it can help promote venous blood return and reduce the possibility of blood retention in the lower limb veins, which helps to reduce the risk of thrombosis, and can also reduce the static state of the leg muscles, promote muscle contraction and relaxation, help increase the venous blood return rate, reduce the possibility of thrombosis stagnation, and prevent venous thromboembolism. After using the device for a period of time, it can be used in conjunction with an intermittent pneumatic pressure therapy device to continuously prevent the legs to promote the patient's blood venous flow rate, so as to prevent deep vein thrombosis. This is a prior art and will not be elaborated on here.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
