Description

Technical Field

[0001] This utility model mainly relates to the field of medical device technology, specifically a limb fixation device for thrombosis treatment. Background Technology

[0002] In the clinical treatment of thrombotic diseases, proper limb immobilization and promotion of blood circulation are crucial for improving the condition and enhancing treatment outcomes. After thrombosis, blood flow to the limb is obstructed. If only conventional and simple immobilization methods are used, it can easily lead to increased blood stasis, which not only hinders thrombus dissolution and absorption but may also cause discomfort such as pain and swelling, and even worsen the condition.

[0003] During thrombosis treatment, targeted, rhythmic flexion, extension, and angle changes of the limbs (especially the legs) are necessary to promote blood return. Existing devices struggle to integrate pressure application and dynamic limb angle adjustment, failing to provide a comprehensive and precise limb immobilization and rehabilitation support solution for thrombosis treatment. Therefore, developing a limb immobilization device for thrombosis treatment that can synergistically achieve pressure intervention and dynamic limb angle adjustment, while also offering good adaptability, has become an urgent need to optimize the thrombosis treatment process, improve treatment outcomes, and enhance patient experience. Utility Model Content

[0004] To achieve the above objectives, this utility model employs the following technical solution: A limb immobilization device for thrombosis treatment includes a base, a pressure airbag fixedly disposed on the inner side of the top of the base, a pedal rotatably connected to the end of the base, a connecting rod hinged to the bottom of the pedal, a slide rod slidably disposed at the bottom of the base, the slide rod being hinged to the connecting rod, and an electric actuator fixedly disposed at the bottom of the base, the electric actuator being drivenly connected to the slide rod.

[0005] Support rods are symmetrically fixed on both sides of the base, and a rotating shaft is fixed between the two support rods. The connecting pedal is rotatably connected to the rotating shaft.

[0006] A U-shaped stop block is fixedly installed on the pedal, and a tension band is fixedly installed on the pedal.

[0007] Two sliding grooves are fixedly provided at the bottom of the base, the sliding rod abuts against the inner wall of the sliding groove, and the end of the sliding rod is fixedly connected to the output end of the electric push rod.

[0008] Compared with the prior art, the beneficial effects of this utility model are: This utility model has a simple structure and is easy to install and use. The pressurized airbag can simulate the pressure environment that promotes blood circulation. The pressure can be precisely controlled by an external air pump to adapt to the patient's condition and medical advice. It can effectively improve blood stasis in the limbs, help to clear thrombi and treat thrombosis, and reduce the risk of aggravating the condition due to poor blood circulation. The electric actuator, slide bar, connecting rod and rotating shaft work together to drive the pedal to rotate flexibly, realize the cycle of toe hooking and pointing movements, dynamically adjust the limb posture, assist in promoting blood return, adapt to the limb rehabilitation needs at different stages of thrombosis treatment, and enhance the treatment's pertinence. U-shaped blocks and tension bands can stably fix the feet and are suitable for patients of different body types; the base, support rod and other structures provide reliable support to ensure the stability of the limb position during treatment.

[0011] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0012] Referring to the accompanying drawings, a limb fixation device for thrombosis treatment includes a base 1, a pressure airbag 2 fixedly disposed on the inner side of the top of the base 1, the pressure airbag 2 being connected to an external air pump, a pedal 3 rotatably connected to the end of the base 1, a connecting rod 4 hinged to the bottom of the pedal 3, a sliding rod 5 slidably disposed at the bottom of the base 1, the sliding rod 5 being hinged to the connecting rod 4, and an electric push rod 6 fixedly disposed at the bottom of the base 1, the electric push rod 6 being drively connected to the sliding rod 5.

[0013] Support rods 7 are symmetrically fixed on both sides of the base 1, and a rotating shaft 8 is fixed between the two support rods. The connecting pedal 3 is rotatably connected to the rotating shaft 8. This structural design drives the connecting pedal 3 to flip.

[0014] A U-shaped stop 9 is fixedly installed on the pedal 3, and a tension band 10 is fixedly installed on the pedal 3. This structural design fixes the foot.

[0015] Two sliding grooves 11 are fixedly provided at the bottom of the base 1, the sliding rod 5 abuts against the inner wall of the sliding groove 11, and the end of the sliding rod 5 is fixedly connected to the output end of the electric push rod 6.

[0016] When using this device, place it in a suitable treatment area, connect the external air pump and the pressure bag 2, and assist the patient in placing their leg on the base 1 with the foot corresponding to the pedal 3. Use the U-shaped stop 9 for initial positioning, and use the tension band 10 to wrap around and fix the foot, stabilizing the limb on the device. Start the external air pump to inflate the pressure bag 2. The inflated air bag applies pressure to the limb on the inner side of the top of the base 1, simulating a pressure environment that promotes blood circulation. The pressure parameters are adjusted according to the patient's condition and doctor's orders. The electric push rod 6 operates, pushing the slide rod 5 to slide along the bottom groove 11 of the base 1. The slide rod 5 drives the pedal 3 to rotate around the pivot 8 through the connecting rod 4, causing the toes to point downwards. After holding for 5-10 seconds, the electric push rod 6 operates in the opposite direction, causing the toes to point upwards, trying to bring the toes as close to the calf as possible. After holding for 5-10 seconds, the electric push rod 6 operates in the opposite direction again, and the cycle is repeated multiple times. During treatment, medical staff observe the patient's limb response and the device's operating status, and adjust the pressure of the airbag 2 and the pedal angle driven by the electric push rod 6 as needed to ensure the treatment is safe and effective. After treatment, the air pump is turned off to release air, the electric push rod 6 is retracted, the restraint band 10 is released, and the patient is assisted in removing the limb to complete the procedure.
