Description

Technical Field

[0001] This invention relates to the field of medical care technology, and in particular to a device for the care of venous thrombosis. Background Technology

[0002] The definition of venous thrombosis is the abnormal coagulation of blood in the lumen of a vein, which changes from a liquid state to a solid state, obstructing the venous lumen and causing venous return obstruction. When caring for venous thrombosis, it is necessary to perform ankle joint exercises. Try to point your toes towards yourself as far as possible, hold for about five seconds, and then slowly press your toes down and hold for five seconds. Repeat this process.

[0003] Application number CN202210045827.9 discloses a bed rest care device for lower extremity superficial vein thrombosis, including a care base, a lower limb elevation and movement module, and a foot positioning module. The care base has a knee joint support telescopic semi-ring on its inner side wall. Both ends of the care base are equipped with electric drive devices. The main shaft of each electric drive device has a worm gear assembly at its end, and the other end of the worm gear assembly has a four-corner slot. The bottom end of the worm gear assembly has a worm wheel assembly, and the inner side of the worm wheel assembly has a connecting transmission rod. The connecting transmission rod is fixed to the knee joint support telescopic semi-ring. This invention, through a linkage mechanism, allows the knee joint support telescopic semi-ring to rotate synchronously with the patient's lower limb, satisfying the knee joint placement requirements of the patient's lower limb in different positions. This ensures that the knee joint support telescopic semi-ring always supports the patient's knee joint, preventing the patient's lower limb from being suspended and causing long-term knee stiffness, which can lead to knee joint wear or even bending deformation.

[0004] Based on the above patent search and understanding of existing applications in venous thrombosis care: 1. Currently, in the care of ankle joints of patients with venous thrombosis, manual assisted care is inefficient and relies on continuous operation by medical staff or family members. It is difficult to ensure the consistency of movement frequency and amplitude, and the care effect is unstable. Furthermore, if the patient's physical strength is insufficient or the movement is not standardized when exercising independently, it is impossible to achieve effective thrombosis prevention and care. Moreover, long-term independent operation can easily lead to fatigue. 2. Some existing nursing devices only focus on auxiliary functions such as knee joint support and lack automated transmission structures for ankle joint-specific care, and cannot accurately simulate the flexion and extension movement trajectory required by the ankle joint.

[0005] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a venous thrombosis care device, in order to achieve a more practical purpose. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a venous thrombosis care device. This device addresses the issues of low efficiency in manual assistance during ankle care for patients with venous thrombosis, reliance on continuous operation by medical staff or family members, difficulty in ensuring consistent movement frequency and amplitude, unstable care effects, and the inability to achieve effective thrombosis prevention and care if the patient's physical strength is insufficient or their movements are not standardized. Furthermore, prolonged independent operation can easily lead to fatigue. Additionally, some existing care devices only focus on knee joint support and lack automated transmission structures specifically designed for ankle joint care, failing to accurately simulate the required flexion and extension movement trajectories of the ankle joint.

[0022] A lower guard plate 101 is fixedly installed at the top center of the base frame 1. An adjusting screw A103 is rotatably connected to the inner center of the adjusting frame 102. An adjusting plate 104 is slidably connected inside the adjusting frame 102. A threaded hole is opened at the top of the adjusting plate 104, and the adjusting screw A103 is threaded through the threaded hole of the adjusting plate 104. An upper guard plate 105 is fixedly installed at the bottom inner end of the adjusting plate 104, and the upper guard plate 105 is located directly above the lower guard plate 101. An extension screw 201 is rotatably connected to the outer end of the extension frame 2. A threaded hole is opened at the rear side of the outer end of the extension slider 202, and the extension screw 201 is threaded through the threaded hole of the extension slider 202. A knob is fixedly connected to the front end of the extension screw 201. The front center of the reciprocating component 305 is fixedly connected to the rear end of the rack frame 306, and the rack frame 306 is located in front of the transmission frame 3.

[0023] A nursing frame 307 is fixedly installed at the front inner end of the transmission frame 3. The nursing frame 307 is located above the front of the lower guard plate 101. A transmission gear shaft 308 is rotatably connected to the rear inner end of the nursing frame 307. The outer end of the transmission gear shaft 308 rotatably passes through the front end of the transmission frame 3. A gear is provided at the outer end of the transmission gear shaft 308. The gear at the outer end of the transmission gear shaft 308 is located inside the rack frame 306. The inner bottom wall of the rack frame 306 has multiple teeth, and the gear at the outer end of the transmission gear shaft 308 is meshed with the inner bottom wall of the rack frame 306. A nursing pedal 309 is fixedly installed at the middle position of the transmission gear shaft 308. The nursing pedal 309 is located directly behind the nursing frame 307.

[0024] The working principle of this invention is as follows: When in use, the patient lies on the bed and the base frame 1 is placed at the end of the bed. At this time, the patient's lower leg is passed through the middle of the lower guard plate 101 and the upper guard plate 105, so that the lower guard plate 101 fits against the lower side of the patient's lower leg, ensuring that the lower leg is in a natural and relaxed state. Rotate the adjusting screw A103 to drive the adjusting plate 104 to move up and down, so that the upper guard plate 105 is lowered to fit against the upper side of the lower leg to complete the leg fixation. The fixation force should be such that it does not affect blood circulation. Next, rotate the adjusting screw B106 to adjust the up and down position of the extension frame 2 at the front end of the adjusting frame 102, so that the nursing pedal 309 is aligned with the patient's foot position. Rotate the extension screw 201 to drive the extension slider 202 to drive the transmission frame 3 to slide back and forth, further fine-tuning the position of the nursing pedal 309 to ensure that the patient's foot can naturally step on the nursing pedal 309. Then, the controller 301 at the outer end of the transmission frame 3 presets the nursing exercise parameters, including the holding time and the number of exercise cycles. After the patient places their foot on the nursing pedal 309, the controller 301 starts the motor 302. After the motor 302 starts, its shaft drives the U-shaped frame 303 to rotate. The U-shaped frame 303 pulls the reciprocating component 305 to slide back and forth inside the transmission frame 3 through the transmission arm 304. The reciprocating component 305 drives the rack frame 306 to move back and forth synchronously. The rack frame 306 meshes with the gear at the outer end of the transmission gear shaft 308, driving the transmission gear shaft 308 to rotate alternately in both directions. The transmission gear shaft 308 drives the nursing pedal 309 in the middle to rotate synchronously, realizing the cycle of "holding the toes up for a maximum of 5 seconds and pressing the toes down for a maximum of 5 seconds", thus completing the ankle joint-specific nursing care. During the nursing process, the patient can pause the device at any time and adjust the position or parameters through the controller 301. After the nursing is completed, the patient can remove the foot and leg fixation to complete the nursing procedure.

[0025] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. The scope of protection of this disclosure shall be determined by the scope of the claims.
