Description

Technical Field

[0001] The present invention relates to the field of intelligent auxiliary exercise devices for preventing lower limb venous thrombosis in patients, and particularly to an intelligent auxiliary exercise device for preventing lower limb venous thrombosis in patients. Background Art

[0002] Association with multiple organ dysfunction: Patients admitted to the ICU usually suffer from multiple organ dysfunction syndrome (MODS), and disorder of the body's blood coagulation function is a common complication. For example, the systemic inflammatory response caused by sepsis activates the coagulation system and inhibits the fibrinolysis process at the same time, resulting in a significant increase in the tendency of blood to coagulate, greatly increasing the probability of lower limb venous thrombosis. According to research, the incidence of lower limb venous thrombosis in sepsis patients during their stay in the ICU is about 30%-50% higher than that of the same disease patients in the general ward. In this situation, traditional preventive measures are difficult to accurately respond to the complex and changeable abnormal coagulation fluctuations, and there is an urgent need for a device that can monitor in real time and dynamically adjust the intervention strategy. Continuous invasive monitoring and pipeline obstruction: In order to monitor the patient's vital signs in real time, the ICU often uses a large number of invasive monitoring devices, such as central venous catheters, arterial indwelling needles, etc. These pipelines not only limit the patient's limb movement, but also become a potential "hotbed" for thrombosis formation due to long-term indwelling. There is literature pointing out that when the central venous catheter is indwelling for more than 5 days, the risk of venous thrombosis in the corresponding limb increases by about 2-3 times. Moreover, in order to maintain the patency of the pipeline and ensure the accuracy of monitoring, medical staff will be more cautious in restricting the patient's leg movements during operation, further reducing the opportunities for natural lower limb activities. The space for conventional simple passive activity assistance devices is extremely limited in this scenario.

[0003] The nursing work intensity in the ICU is extremely high. Nurses need to simultaneously take care of multiple critical tasks such as respiratory support, circulation management, and wound care for critically ill patients, and it is difficult to spare sufficient time to regularly perform standardized leg massage and exercise assistance operations for each patient. Investigations show that on average, each ICU nurse is responsible for 2-3 patients per shift, and the special nursing time allocated to a single patient for thrombosis prevention is less than 15 minutes, which cannot guarantee multiple high-quality artificial interventions per day. There is an urgent need for automated equipment to share the workload.

[0004] Influence of professional skill differences: The rehabilitation nursing skill levels of different nurses vary. Even if there is time for artificial assisted exercise, it is difficult to unify the standards for the manipulation strength and movement amplitude. It may cause soft tissue damage to the patient's legs due to improper force application, or it may not effectively promote blood circulation due to inadequate movements. The intelligent assisted exercise device can eliminate the differences in manual operations through preset precise programs and stably output safe and effective rehabilitation assistance Therefore, it is necessary to provide a new intelligent auxiliary exercise device for preventing lower limb venous thrombosis in patients to solve the above technical problems.

[0016] It should be noted that: the motor inside the installation box 31 is a double-shaft motor, and the connecting plates 38 are arranged oppositely. One end of the connecting plate 38 is key-connected to the output shaft of the double-shaft motor. One end of the connecting plate 38 is hinged to the outside of the foot support plate 37. The support arm 32 and the installation box 31 are injection-molded integrally. There is a metal support frame inside the support arm 32. Both sides of the rotating rod 33 are slidably inserted into the inside of the movable rod 34. The limit buckle on the foot support plate 37 is a mother-son snap buckle. A magic tape is arranged on the paste ring 36. Starting buttons for controlling the motor inside the installation box 31 and adjusting the motor 8 are respectively arranged on one side of the installation box 31.

[0017] In the specific implementation process, as Figure 1 and Figure 2 shown, a reciprocating lead screw 4 is slidably inserted into the inside of the movable rod 34. A moving block 5 is screwed on the outside of the reciprocating lead screw 4. The lifting rope 35 is slidably inserted into the inside of the moving block 5.

[0018] Refer to Figure 2 and Figure 3 shown, a ratchet 6 is arranged on the outside of one end of the movable rod 34. One end of the reciprocating lead screw 4 penetrates through the inside of the movable rod 34 and extends to the outside and is key-connected to the inside of the ratchet 6. A ratchet pawl 7 is rotatably arranged on the movable rod 34 and is used in cooperation with the ratchet 6. The outside of the ratchet pawl 7 is clamped and matched with the tooth grooves on the ratchet 6.

[0019] It should be noted that: one end of the reciprocating lead screw 4 is rotatably connected to the inside of the movable rod 34. One end of the reciprocating lead screw 4 is key-connected to the ratchet 6. Limit grooves are respectively opened on both sides of the movable rod 34. The moving block 5 is slidably inserted into the inside of the limit groove, which is convenient for limiting the moving block 5 and preventing the moving block 5 from rotating together with the reciprocating lead screw 4.

[0020] Refer to Figure 2 and Figure 3As shown in the figure, an adjustment motor 8 is provided on one side of the support arm 32. The output shaft of the adjustment motor 8 penetrates through one side of the support arm 32 and is key-connected to the rotating rod 33.

[0021] Reference Figure 3 and Figure 4 As shown in the figure, a sliding groove 9 is formed in one side baffle 2. One side of the mounting box 31 is connected with a positioning rod 10. One end of the positioning rod 10 is slidably inserted into the interior of the sliding groove 9, and a fastening bolt 11 is screwed on the positioning rod 10.

[0022] It should be noted that the adjustment motor 8 is fixed to one side of the support arm 32 by screws. The model of the adjustment motor 8 is a stepping motor, and the angle of each rotation can be controlled.

[0023] The working principle of an intelligent auxiliary exercise device for preventing lower limb venous thrombosis in patients provided by the present invention is as follows: During use, medical staff can place the side with the positioning rod 10 on one side of the baffle 2, so that the positioning rod 10 is inserted into the interior of the sliding groove 9. Then, according to the position of the patient's leg, the height of the mounting box 31 is adjusted as needed. When adjusted to an appropriate position, the fastening bolt 11 is rotated by a tool, so that one side of the fastening bolt 11 is close to the other side of the baffle 2, and the mounting box 31 is positioned on one side of the baffle 2. After the fixation is completed, the adhesive ring 36 is placed under the patient's leg. The adhesive ring 36 is wound around the patient's leg and bonded by Velcro. The patient's foot is placed on the foot support plate 37 and then fixed by a limit buckle. After the buckles on the adhesive ring 36 and the foot support plate 37 are fixed, the medical staff can control the motor to start through the corresponding button on one side of the mounting box 31. The motor drives the connecting plates 38 on both sides to move clockwise respectively. Since the connecting plates 38 on both sides are arranged oppositely, the connecting plates 38 drive the foot support plate 37 to move forward and backward. The foot support plate 37 drives the patient's foot to move reciprocally. The adhesive ring 36 drives the suspension rope 35 to move. The front-back shaking of the suspension rope 35 causes the movable rod 34 to rotate. When the patient's leg feels uncomfortable due to the fixed position of the adhesive ring 36, the pawl 7 can be toggled to separate it from the ratchet wheel 6, and then the ratchet wheel 6 is rotated by the handle on the ratchet wheel 6. The ratchet wheel 6 drives the reciprocating lead screw 4 to rotate. The moving block 5 moves along the outer surface of the reciprocating lead screw 4, so that the distance between the moving blocks 5 inside the movable rods 34 on both sides becomes larger, improving the comfort of the patient. The inclination angle of the rotating rod 33 can also be adjusted by the adjustment motor 8.
