Description

Technical Field

[0001] The present invention relates to the technical field of disease prevention, and more specifically, to a thrombus risk prediction assistance device. Background Art

[0002] A thrombus refers to a small mass formed on the surface of the exfoliation or repair site of the inner surface of blood vessels in the cardiovascular system, which is composed of insoluble fibrin, deposited platelets, accumulated white blood cells and red blood cells. Under normal circumstances, blood itself has coagulability, which helps the human body play roles such as local coagulation and hemostasis in case of trauma and bleeding. However, if the balance of the coagulation and anticoagulation mechanisms is disrupted during the coagulation process, it is likely to lead to thrombus formation.

[0003] Existing thrombus risk prediction assistance devices usually lack the physical prevention function of thrombus, and patients need to perform relevant preventive exercises by themselves. Since the main population suffering from venous thrombus is long-term bedridden patients, when such patients perform relevant preventive exercises, they need the assistance of others, which reduces the exercise frequency of patients and increases the risk of thrombus occurrence in patients. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0025] The present invention will be further described in detail below with reference to the drawings and embodiments:

[0026] Embodiment:

[0027] As Figures 1 to 4 shown, the present invention provides an auxiliary device for predicting thrombus risk, including a support plate 2 and an exercise component. The exercise component includes a connecting frame 22 hinged to one end of the support plate 2. First fixed shafts 12 are arranged on both sides of the support plate 2, and second fixed shafts 24 are arranged on both sides of the connecting frame 22. A control rod 8 is connected between the first fixed shaft 12 and the second fixed shaft 24 on the same side. A seat plate 6 is hinged to the other end of the support plate 2. A motor 7 is arranged on one side of the seat plate 6, and a connecting shaft 11 arranged on one side of the support plate 2 is coaxially connected to the output shaft of the motor 7. A test component is arranged at the bottom end of the connecting frame 22.

[0028] As Figure 2 and Figure 3 shown, the test component includes a moving frame 13 slidably clamped at the bottom end of the connecting frame 22. A support plate 15 is arranged on the moving frame 13. An elastic band 16 is connected to the moving frame 13. The top end of the elastic band 16 is connected to the connecting frame 22 through a limiting component.

[0029] As Figure 2 and Figure 3 shown, the limiting component includes a fixed frame 20 arranged on one side of the connecting frame 22. A sliding plate 27 is slidably clamped on one side of the fixed frame 20. A clamping groove 21 is formed on the fixed frame 20. A sliding rod 26 penetrating through the sliding plate 27 is slidably clamped in the clamping groove 21. A limiting plate 19 is arranged at the top end of the sliding rod 26. A spring 23 is connected to the bottom end of the sliding plate 27. The free end of the spring 23 is connected to a connecting plate 14 arranged at the top end of the elastic band 16.

[0030] As Figure 2 and Figure 4 shown, a pair of connecting blocks 17 are arranged on both sides of the elastic band 16. A dovetail groove 33 is formed at one end of the connecting block 17. Two pairs of dovetail blocks 31 are arranged on the side of the moving frame 13 close to the elastic band 16. The two pairs of dovetail blocks 31 are respectively slidably clamped in the two pairs of dovetail grooves 33.

[0031] As Figure 2 and Figure 4 shown, a control board 37 is connected to the outside of each of the two pairs of connecting blocks 17 through a connecting rope 36. The two control boards 37 on the same side of the elastic band 16 are connected through a rotating rod 35. The rotating rod 35 is rotatably clamped on both sides of the moving frame 13.

[0032] As Figures 2 to 4As shown, a U-shaped groove 28 is provided on the moving frame 13. A first rewinder is arranged in the U-shaped groove 28. Both ends of the first rewinder are connected with a pulling rope 25. A limiting block 29 is respectively arranged on both sides of the moving frame 13. The free ends of the two pulling ropes 25 respectively pass through a limiting block 29 and are connected with an extension plate 34 connected to the outer side of two rotating rods 35. Among them, the first rewinder is connected with the motor 7 through an electric circuit.

[0033] As Figure 4 shown, a guide wheel 30 is rotatably connected to one end of the dovetail block 31 close to the control board 37, and the connecting rope 36 is stuck on the outer edge of the guide wheel 30.

[0034] The elastic band 16 can cooperate with the moving frame 13 to compress the back side of the patient's calf. On the one hand, it can cooperate with the fastening component arranged on the moving frame 13 to fix the patient's leg. On the other hand, it can test the risk of lower limb thrombosis of the patient by adjusting the compression force of the elastic band 16. Whether there is pain and the degree of pain are used to help the patient judge the probability of thrombosis. When it is necessary to tighten the elastic band 16 to compress the patient's calf muscles, the first rewinder arranged in the U-shaped groove 28 is driven to pull the pulling ropes 25 connected to both ends thereof. Since the pulling ropes 25 pass through the limiting blocks 29 arranged on both sides of the moving frame 13 and are connected with the extension plates 34 arranged on the outer sides of the rotating rods 35, when the first rewinder pulls the pulling ropes 25, the two rotating rods 35 will be driven to rotate. Since both ends of the rotating rod 35 are respectively connected with two control boards, the control boards will rotate synchronously, so that the connecting rope 36 connected to one end of the control board will pull the connecting block 17 to move along the dovetail block 31 arranged on the moving frame 13. Since the control boards are arranged on both sides of the elastic band 16, the movement of the control boards will drive the elastic band 16 to extend horizontally, thereby compressing the patient's leg.

[0035] As Figure 1 and Figure 2 shown, multiple fastening components are arranged on the moving frame 13. The fastening component includes a binding band 4 connected to the outside of the moving frame 13. An elastic band 9 is arranged on one side of each binding band 4. A clamping block 3 connected to the free end of the elastic band 9 is clamped in a buckle 5 connected to the free end of the binding band 4.

[0036] The fastening component can fix the patient's calf to the moving frame 13. By buckling the clamping block 3 and the buckle 5 on the same horizontal plane, the patient's calf can be clamped and fixed in cooperation with the elastic band 16.

[0037] As Figure 2 and Figure 4 shown, a pair of arc-shaped frames 18 are arranged at the bottom end of the moving frame 13. A massage roller 10 is clamped between the two arc-shaped frames 18. Both ends of the massage roller 10 are connected with a second rewinder arranged in the moving frame 13 through a traction rope 32. The second rewinder is connected with the motor 7 through an electric circuit.

[0038] As Figure 1As shown, grooves 1 are provided on both the seat plate 6 and the support plate 2, and the length of the support plate 2 can be adjusted along the direction connecting the support plate 2 and the seat plate 6.

[0039] Specific usage method and function of this embodiment:

[0040] In the present invention, the exercise component provided can help bedridden patients perform leg muscle exercises, reduce the risk of lower limb thrombosis in patients by accelerating blood circulation in the patients' legs. When it is necessary to exercise the lower limbs of the patient, let the patient place the leg on the side to be exercised on the support plate 2, and at the same time place the hip on the seat plate 6 on the same side. Adjust the length of the support plate 2 and the body position of the patient so that the patient's hip and thigh parts are placed above the grooves 1 of the seat plate 6 and the support plate 2, and at the same time keep the inner side of the patient's knee joint at the hinged position of the support plate 2 and the connecting frame 22. Then fix the patient's calf through the moving frame 13 provided at the bottom end of the connecting frame 22. When the patient needs to lift the calf, drive the control rods 8 on both sides of the connecting frame 22 to extend. Since the two ends of the control rod 8 are respectively hinged to the first fixed shaft 12 on both sides of the support plate 2 and the second fixed shaft 24 on both sides of the connecting frame 22, the extension of the control rod 8 will drive the connecting frame 22 to rotate along one end of the support plate 2. During the rotation of the connecting frame 22, the moving frame 13 will be driven to rotate synchronously. At the same time, since the moving frame 13 is fixedly connected to the patient's calf, the moving frame 13 will slide a certain distance along the connecting frame 22. At this time, the elastic band 16 provided on the moving frame 13 will slide synchronously, so that the connecting plate 14 provided at one end of the elastic band 16 pulls the spring 23 to prevent the moving frame 13 from detaching from the connecting frame 22;

[0041] When the patient needs to exercise the ankle joint, lift the toes, and the patient's toes will lift the massage roller 10 slidably clamped between the two arc-shaped frames 18, so that both ends of the massage roller 10 pull the traction rope 32. The user can adjust the damping of the second winding device to change the moving difficulty of the massage roller 10, thereby helping the patient exercise the muscle tissues near the ankle joint.

[0042] The above are only embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be subject to the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
