Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a quantifiable ankle pump trainer. Background Technology

[0002] Ankle pump exercises promote blood circulation and lymphatic drainage in the lower limbs through ankle joint movements, much like a pump. This not only prevents and alleviates lower limb pain and postoperative swelling, but also significantly reduces the risk of deep vein thrombosis in the lower limbs and is crucial for postoperative functional recovery. Clinically, this method is routinely used for postoperative lower limb patients, those who are bedridden for extended periods, and patients with high blood viscosity; it is effective and widely applied.

[0003] Because of the different foot sizes of different people, when performing ankle pump training, people with larger feet need to exert more force. Due to the leverage principle, people with larger feet require less effort compared to people with smaller feet. If the training resistance is not adjusted according to the size of the feet, it is easy to result in poor training effect. In addition, people with larger feet need to perform more training movements, making it difficult for medical staff to quickly and accurately determine the appropriate number of training sessions. Summary of the Invention

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figures 1-6An embodiment of the present invention provides a quantifiable ankle pump trainer, comprising a base 10, a sleeve 1 fixedly disposed on the top of the base 10, four L-shaped telescopic rods 8 fixedly disposed on the side wall of the sleeve 1, a judgment mechanism 7 fixedly disposed at the end of the four L-shaped telescopic rods 8, a resistance mechanism 6 disposed on the side wall of the sleeve 1, a telescopic mechanism 5 rotatably sleeved on the resistance mechanism 6, a strap 4 fixedly disposed on the top of the telescopic mechanism 5, a display screen 2 fixedly disposed on the top of the sleeve 1, and two buttons 3 fixedly disposed on the top of the sleeve 1. First, the patient places their foot on the telescopic mechanism 5, then secures the foot with the strap 4. The telescopic mechanism 5 is then stretched according to the size of the foot, so that its length matches the foot. The telescopic mechanism 5 extends and retracts, causing the resistance mechanism 6 to adaptively adjust the appropriate training resistance. The extension of the telescopic mechanism 5 also causes the judgment mechanism 7 to move, which in turn causes the L-shaped telescopic rod 8 to extend. The movement of the judgment mechanism 7 adaptively adjusts the training stroke, and the judgment mechanism 7 determines whether the training is effective and displays the number of effective training sessions on the display screen 2. When the next training session begins, pressing the button 3 resets the count, and the number of effective training sessions is recorded again.

[0017] Specifically, the resistance mechanism 6 includes two turntables 61, two torsion springs 62, two first rotating shafts 63, two rotating cylinders 64, two second rotating shafts 68, and a resistance component. The two first rotating shafts 63 are rotatably mounted on the side wall of the sleeve 1. The two rotating cylinders 64 are respectively fixedly mounted at the ends of the two first rotating shafts 63. The two first rotating shafts 63 are hollow. The two second rotating shafts 68 are respectively rotatably mounted inside the two first rotating shafts 63. The two turntables 61 are respectively fixedly mounted at the ends of the two second rotating shafts 68. The two ends of the two torsion springs 62 are respectively fixedly connected to the corresponding rotating cylinders 64 and turntables 61. The resistance component is located between the two second rotating shafts 68. The rotation of the second rotating shafts 68 drives the turntables 61 to rotate, and the turntables 61 cause the torsion springs 62 to tighten, thereby increasing the training resistance. This achieves adaptive adjustment according to the user's foot size, ensuring a certain level of training resistance for different groups of people, thus achieving a good and effective training effect.

[0018] Specifically, the telescopic mechanism 5 includes a connector plate 51, a telescopic plate 52, two telescopic spring posts 53, and two first springs 54. The connector plate 51 is fixedly sleeved on two first rotating shafts 63. One end of each of the two telescopic spring posts 53 is fixedly mounted on the end of the connector plate 51, and the telescopic plate 52 is fixedly mounted on the other end of each telescopic spring post 53. The two first springs 54 are respectively sleeved on the two telescopic spring posts 53. The user's foot moves the telescopic plate 52, which in turn extends the telescopic spring posts 53. Under the action of the first springs 54, the end of the telescopic plate 52 always fits against the patient's toes. This mechanism is suitable for people with various foot sizes and automatically measures the user's foot size, facilitating subsequent adjustment of training resistance and effective training stroke.

[0019] Specifically, the resistance assembly includes a gear 65, a rack 66, and a fixing plate 67. The gear 65 is fixedly disposed between two second rotating shafts 68. The insertion plate 51 has a receiving groove inside, and the rack 66 is slidably disposed inside the receiving groove. The fixing plate 67 is fixedly disposed at the end of the rack 66. The movement of the telescopic plate 52 moves the fixing plate 67, which in turn moves the rack 66. The rack 66's movement causes the gear 65 to rotate, which in turn rotates the second rotating shafts 68. This allows for adjustment of training resistance based on foot size, addressing the issue of insufficient training resistance due to greater torque in individuals with larger feet, while also facilitating excessive training resistance in individuals with smaller feet. It is highly adaptable, requires no manual judgment, is simple to operate, and allows for precise adjustment.

[0020] Specifically, the gear 65 meshes with the rack 66, and the telescopic plate 52 is fixedly connected to the fixed plate 67.

[0021] Specifically, the judgment mechanism 7 includes an arc-shaped plate 71, a judgment plate 72, four sliding rods 73, four sliding grooves 74, a T-shaped block 75, a pressure sensor 76, two pulleys 77, and an arc-shaped groove 78. The arc-shaped plate 71 is fixedly installed at the end of the L-shaped telescopic rod 8. The arc-shaped groove 78 is installed inside the arc-shaped plate 71. The four sliding grooves 74 are installed on the inner side wall of the sleeve 1. One end of each of the four sliding rods 73 is slidably installed inside the corresponding sliding groove 74. The judgment plate 72 is fixedly installed at the other end of the four sliding rods 73. The two pulleys 77 are rotatably installed at the end of the judgment plate 72. The T-shaped block 75 is fixedly installed at the bottom of the telescopic plate 52. The pressure sensor 76 is fixedly installed at the bottom of the T-shaped block 75. The movement of the telescopic plate 52 drives the movement of the T-shaped block 75, which in turn drives the movement of the arc-shaped plate 71. The movement of the arc-shaped plate 71 further drives the movement of the L-shaped telescopic plate 52. Due to the limiting sliding setting of the pulley 77 within the arc-shaped groove 78, and the vertical sliding setting of the judgment rod and slide rod 73 within the slide groove 74, the judgment rod moves downwards along the arc-shaped groove 78 when the arc-shaped plate 71 moves horizontally. This causes a change in the contact stroke between the pressure sensor 76 and the end of the judgment rod until the pressure sensor 76 contacts the end of the judgment rod for three seconds. The pressure sensor 76 then transmits an electrical signal to the display screen 2 for display and recording of the number of times the patient has trained. This achieves adaptive adjustment of the patient's effective training stroke based on foot size, eliminating the need for manual judgment, ensuring precise settings, and recording the number of effective training sessions, providing intuitive monitoring of the patient's training effect.

[0022] Specifically, the two pulleys 77 slide within the arc-shaped groove 78, and the T-shaped block 75 slides within the arc-shaped groove 78 to limit movement.

[0023] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
