[0002] Deep vein thrombosis refers to abnormal blood coagulation in the deep veins. It is a venous reflux disorder in the lower extremities. Thrombosis mostly occurs in the immobilization state (especially major orthopedic surgery). The pathogenic factors are slow blood flow, venous wall damage and hypercoagulable state. After thrombosis, except for a few that can be self-ablated or confined to the site of occurrence, most will spread to the deep vein trunks of the entire limb. If not diagnosed and treated in time, most will develop into sequelae of thrombosis, affecting the patient's quality of life for a long time. Some patients may also suffer from pulmonary embolism, resulting in extremely serious consequences. Deep vein thrombosis in the lower extremities can be diagnosed through examinations, including ultrasound examinations, CT scans, MRI examinations, etc.
[0003] However, currently, ultrasound examination requires the patient to lie flat, and patients are physically weak and have difficulty in operating. Climbing onto and getting off the examination bed is slow and difficult, resulting in a long preparation time for the examination, reduced detection efficiency, and low safety. Therefore, the patent of this invention provides a deep vein thrombosis detection device for the lower limbs to meet people's needs.

The plate 10 and the extension plate 7 are symmetrically provided with circular holes on both sides, and the guide cylinder 9 is movable through the circular holes. The bottom end of the foot pedal 10 is fitted with the elastic buffer plate 8. Through the coordinated use of the pad 4 and the foot pedal 10, the patient can maintain a sitting posture for detection. There is no need to lie flat when performing deep vein thrombosis detection of the lower limbs, which is more convenient to operate, reduces the time required for lying down and standing up, and is safer. At the same time, through the coordinated use of the hydraulic telescopic rod 6 and the guide groove 3, the height of the pad 4 can be adjusted so that the height of the pad 4 matches the height and leg length of the patient, so that the lower limbs can be smoothly placed on the foot pedal 10, which is convenient for medical staff to examine them. The elastic buffer plate 8 and the guide cylinder 9 play a role of buffering and protection for the foot pedal 10, relieve the force when the lower limbs fall, and support the patient's lower limbs after they are placed to keep them in a relaxed state.
[0027] A fixing box 11 is fixedly installed at one end of the foot pedal 10, and an electric push rod 12 is symmetrically fixedly installed inside the fixing box 11. A limiting strip 13 is fixedly connected between the ends of the two electric push rods 12. An arc-shaped limiting block 14 is symmetrically fixedly installed at one end of the top of the foot pedal 10 away from the limiting strip 13. The bottom end of the limiting strip 13 fits with the top of the foot pedal 10. An arc groove is opened at one end of the two arc-shaped limiting blocks 14, and the arc groove faces the limiting strip 13. The position of the limiting strip 13 is adjusted by using the electric push rod 12, and the limiting strip 13 is used to move forward to contact the patient's heel, so that the limiting strip 13 and the arc-shaped limiting block 14 can clamp the patient's foot firmly from the front and back directions, thereby improving the stability during the inspection and preventing the deviation during the inspection from causing the error of the inspection result.
[0028] A mounting seat 15 is fixedly mounted on the top of the fixed vertical plate 2, a B-ultrasound machine 16 is fixedly mounted on the top of the mounting seat 15, and a detection probe 17 is fixedly connected to one end of the B-ultrasound machine 16;
[0029] Movable wheels 18 are installed at the four corners of the bottom end of the base 1, and fixed strips 19 are symmetrically fixedly installed on both sides of the base 1. Adjusting studs 20 are installed through both ends of the two fixed strips 19, and the bottom ends of the adjusting studs 20 are fixedly connected with support blocks 21. The adjusting studs 20 and the fixed strips 19 are connected by threads, and the top ends of the adjusting studs 20 are fixedly connected with rotating round blocks. The use of the movable wheels 18 improves the flexibility of the equipment movement, making it more convenient to carry and transfer. At the same time, the height position of the support block 21 can be adjusted by using the adjusting studs 20, and the base 1 is supported and limited during the detection process to improve the stability of the equipment during detection.
[0030] The working principle and use process of the patent of the present invention are as follows: First, the staff uses the moving wheel 18 to push the equipment to the predetermined detection position, and adjusts the position of the support block 21 by rotating the adjustment stud 20, so that the support block 21 gradually descends and is close to the ground, so as to support and stabilize the bottom of the equipment. The patient who needs to undergo lower limb detection sits directly on the pad 4, with both feet placed on the foot pedal 10. The elastic buffer plate 8 has a certain deformation buffering capacity, which plays a role in buffering and stabilizing the force impact on the foot pedal 10. When the pad 4 is not high enough, the patient's foot will squeeze it, and the elastic buffer plate 8 will be squeezed and deformed. The squeezing and deformation of the elastic buffer plate 8 is used to provide a certain relief space for the patient to prevent The legs are folded and squeezed to produce discomfort. According to the height and leg length of the patient, the inclination angles of the two feet after placement are different. The hydraulic telescopic rod 6 is extended or contracted to push the pad 4 up and down. The movable block 5 always slides along the guide groove 3, which plays a guiding and stabilizing role for the pad 4 and improves the stability of the pad 4. The sole of the patient's foot is flat on the surface of the foot pedal 10. After the pad 4 is raised and lowered to a certain degree, the patient's thigh and calf are at a 90-degree angle. The medical staff controls the hydraulic telescopic rod 6 to stop extending and retracting, and the elastic buffer plate 8 is deformed and restored to its original state, supporting the foot pedal 10 and the patient's foot, so that the patient's lower limbs can remain relaxed, which is convenient for exposing the thigh and calf of the lower limbs, providing great convenience for comprehensive detection;
[0031] The two toes of the patient are respectively in close contact with the two arc-shaped limit blocks 14, and the electric push rod 12 extends forward to push the limit strip 13 forward until the limit strip 13 is in contact with the heel of the patient, thereby clamping the patient's foot firmly and preventing it from shifting during detection. The medical staff uses the B-ultrasound machine 16 and the detection probe 17 to detect the patient's lower limbs, and the patient's lower limbs are kept in a vertical state when sitting, and the detection probe 17 is used to scan them to detect whether there is a blood clot inside.
[0032] Finally, it should be noted that the above is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
