Description

Technical Field

[0001] The utility model relates to a training device for ankle joints, in particular to a horizontal ankle pump exercise auxiliary device. Background Art

[0002] According to doctors, ankle pump exercise is the flexion and extension of the ankle joint. As for why it is called a "pump", it is because the blood circulation in the lower limbs requires power, and the "pump" plays a driving role in blood circulation. The flexion and extension of the ankle joint mainly involves the calf muscles. The contraction and relaxation of the calf muscles play the role of a "muscle pump". This "pump" can promote blood circulation in the lower limbs, increase blood return, and prevent deep vein thrombosis. Therefore, the most important function of the ankle pump is to prevent deep vein thrombosis in the lower limbs.

[0003] Whether they are hospitalized patients or patients at home, most of the ankle pump exercises they use are self-training, that is, they only rely on their own subjective judgment to conduct training, which makes it difficult to better control the amplitude, intensity and time of training, and the training effect is discounted.

[0004] In order to improve the training effect, someone invented a multifunctional ankle pump trainer and its training method (patent authorization announcement number CN111821655B). The specification thereof (paragraph 80) mentions that if the patient performs hook-up and step-down training, the medical staff screws the fixing bolt 260 into the adjusting screw hole 810 in the middle of the second motion track 400 through the fixing hole 220, fixes the relative position of the foot fixing plate 200 and the second motion track 400, and then the patient performs the hook-up (step-down) action of the foot plate under the guidance and protection of the medical staff. When the pressure sensor 500 touches the limit bolt 820, the display screen shows that the patient is The patient's muscle force reaches the preset value, and the controller 610 controls the speaker 620 to emit a prompt sound and start timing. During the timing process, the patient's foot force should be greater than the preset value, otherwise the timing will be restarted. When the timing reaches the time specified by the medical staff, the patient performs the stepping (hooking) action of the foot, and the training regulations are the same as the hooking (stepping) action. After the patient completes one hooking and stepping action, the controller 610 counts one effective training, and the controller 610 controls the speaker 620 to emit a prompt sound. When the count of the controller 610 reaches the preset value, the patient completes the hooking and stepping training.

[0005] The above invention patent technology enhances the training effect by setting a pressure sensor to monitor the amplitude, strength and time of ankle pump movement. However, it is found through research that the pressure sensor 500 and the limit bolt 820 are in hard contact. When the patient applies force, there is no buffer between the pressure sensor 500 and the limit bolt 820, and the pressure sensor is easily damaged by impact. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See Figure 1This embodiment discloses a horizontal ankle pump exercise assisting device, including a calf support assembly 1, a pedal assembly 2 and a monitoring assembly 3, wherein the pedal assembly 2 is located between the calf support assembly 1 and the monitoring assembly 3. Since the entire device is exercised in a supine position, the calf support assembly 1 is required to position the calf to prevent incorrect posture from affecting the exercise effect. The pedal assembly 2 is used to support the sole and heel of the foot, and swings with the movement of the foot, triggering the monitoring assembly 3 during the swinging process. The monitoring assembly 3 directly monitors the contact pressure and time of the pedal assembly 2, and indirectly reflects the strength and time of the foot during the ankle pump exercise.

[0022] See Figure 1 The calf support assembly 1 mainly includes a calf support plate 10, which is in the shape of a rectangular parallelepiped as a whole, and its length matches the length of the calf of an ordinary adult. In order to further match the shape of the human calf and increase comfort, a groove 11 is provided in the middle position of the calf support plate 10 along its length direction, and the groove 11 is arc-shaped and concave, which can effectively reduce the pressure on the calf muscles. In order to further fix the calf and prevent the wrong posture from affecting the exercise effect, a plurality of first straps 12 (3 are shown in the figure, but the number should not be limited) are fixedly provided on one side of the calf support plate 10, and each strap is provided with a Velcro hook surface at the front end and a Velcro velvet surface at the rear end; a plurality of first connecting buckles 13 (3 are shown in the figure, but the number should not be limited) are fixedly provided on the other side of the calf support plate 10; the first strap and the first connecting buckle are detachably connected one by one, that is, the strap passes through the connecting buckle and then folds back, so that the Velcro hook surface and the Velcro velvet surface are adhered to complete the detachable connection.

[0023] The footrest assembly 2 is located at the end of the calf support plate 10, and mainly includes a pedal 20, two support columns 21 and two spring sheets 22. The pedal 20 is used to support the foot, the two support columns 21 are used to support and lift the pedal 20, and the two spring sheets 22 are used to generate a force relationship with the monitoring assembly 3 (i.e., squeeze the monitoring assembly).

[0024] in,

[0025] See Figure 2The pedal 20 includes a heel support plate 200 and a sole support plate 201 which are arranged perpendicularly to each other, so that the overall shape of the pedal 20 is "L" shaped. In order to stabilize the foot on the pedal 20 better and to enable the pedal 20 to be hooked back following the ankle pump movement, a second strap 23 is fixedly arranged on one side of the heel support plate 200, and a second connecting buckle 24 corresponding to the second strap 23 is fixedly arranged on the other side. The second strap 23 and the second connecting buckle 24 are detachably connected to each other, that is, the strap passes through the connecting buckle and then folds back, so that the Velcro hook surface and the Velcro velvet surface adhere to each other, completing the detachable connection. A third strap 25 is fixedly arranged on one side of the sole support plate 201, and a third connecting buckle 26 corresponding to the third strap 25 is fixedly arranged on the other side; the third strap and the third connecting buckle are detachably connected to each other, that is, the strap passes through the connecting buckle and then folds back, so that the Velcro hook surface and the Velcro velvet surface adhere to each other, completing the detachable connection.

[0026] The two support columns 21 are fixed and erected on the calf support plate 10, and are respectively located on the left and right sides of the pedal 20. The left and right sides of the pedal 20 are respectively provided with a rotating shaft 202, and the positions of the two support columns 21 corresponding to the rotating shaft are provided with a rotating hole, and the rotating shaft 202 can be rotatably inserted into the rotating hole. After the connection is completed, the pedal 20 has no direct contact with the calf support plate 10 and can swing freely.

[0027] Two spring sheets 22 are fixed and arranged in an up-and-down arrangement on the back of the pedal 20 (away from the calf support plate 10 and close to the monitoring component 3). Both spring sheets 22 are in a "W" shape or extend in this direction. When the pedal 20 swings, the two spring sheets 22 are driven to move forward and backward. The two spring sheets 22 are mainly used to provide a buffer force to reduce direct collisions, and can also provide a reaction force to the pedal 20, so that the patient can perform a resistance ankle pump exercise.

[0028] The monitoring component 3 mainly includes a housing 30 , a controller 34 , two pressure sensors 31 and an audio-visual reminder module.

[0029] See Figure 3 and Figure 4The housing 30 is a square hard shell, which is mainly used to accommodate the above-mentioned electronic components and to contact the two spring sheets 22. Since the distance between the housing 30 and the two spring sheets 22 largely determines the swing amplitude of the pedal 20, in order to make the auxiliary device of this embodiment adaptable to more patients with different conditions, that is, in order to adjust the swing amplitude of the pedal 20, a sliding assembly is provided between the calf support plate 10 and the housing 30. The sliding assembly includes two slide rails 40, two latch teeth 41, a rotating shaft 42, and two torsion springs 43. In order to cooperate with the sliding assembly, two mutually parallel slide grooves 100 are provided in the calf support plate 10, and the openings of the two slide grooves 100 are located at one end close to the housing 30 and extend along the length direction of the calf support plate 10. The two slide rails 40 are respectively inserted into the two slide grooves 100, and a rack 44 is provided on the upper surface of each slide rail 40. The two latching teeth 41 are also respectively located in the two slide grooves 100 and respectively located above the corresponding slide rails 40, and can be engaged with the racks 44 on the upper surface of the slide rails 40. Once engaged, the movement of the two slide rails 40 is restricted. The rotating shaft 42 can be rotatably inserted into the calf support plate 10. The rotating shaft 42 is located above the two slide rails 40 and is perpendicular to the two slide rails 40. It is fixedly connected through the two latching teeth 41, so rotating the rotating shaft 42 can drive the two latching teeth 41 to rotate, thereby causing the latching teeth 41 to engage and disengage with the racks 44. Two torsion springs 43 are respectively sleeved on the rotating shaft 42, and one end of each spring abuts against the calf support plate 10, and the other end abuts against the latching teeth 41, which are used to cause the two latching teeth 41 to engage with the racks 44 of the two slide rails 40. Therefore, when it is necessary to adjust the distance between the shell 30 and the two spring sheets 22, the rotating shaft 42 is rotated clockwise and maintained (the position relationship shown in the figure is clockwise), thereby driving the two latch teeth 41 to flip up. After the two latch teeth 41 are flipped up, they are disconnected from the rack 44, and the two slide rails 40 can slide freely in the two slide grooves 100 to complete the distance adjustment. After the adjustment is completed, the rotating shaft 42 is released, and the two latch teeth 41 rotate counterclockwise and reset under the action of the torsion spring 43, and re-engage with the two racks 44, the two slide rails 40 are limited, and the shell 30 cannot move.

[0030] The controller is installed in the shell 30; two pressure sensors 31 are respectively coupled to the controller and installed on the outer wall of the shell 30, facing the two spring sheets 22; the sound and light reminder module is coupled to the controller, including a first switch tube, a second switch tube, a speaker 32 and a flashing light 33, wherein the first switch tube and the second switch tube are installed in the shell 30, and the speaker 32 and the flashing light 33 are installed on the upper side of the shell 30.

[0031] See Figure 5The controller model is STC32G single-chip microcomputer U3, which integrates a 12-bit high-speed ADC converter. The ADC converter can convert analog signals into digital signals. Therefore, the sensing signals (analog signals) output by the two pressure sensors 31 are first converted into digital signals after entering the input end of the controller. In this embodiment, the two pressure sensors 31 use MPX5010 pressure sensor chips U1 and U2, and adopt SOP packaging. Pin 2 is connected to the power supply, pin 3 is grounded, and pin 4 is the output and connected to the AD conversion input pin of the controller. The controller also integrates a powered erasable programmable read-only memory that stores pressure thresholds and time thresholds. Therefore, in order to facilitate the adjustment of the thresholds, a touch screen 35 ( Figure 5 The pressure threshold and time threshold are adjusted through the touch screen 35. A timer is also integrated inside the controller to calculate the continuous input time of the sensor signal. The control end (P1.1) of the controller is coupled to the base of the first switch tube Q1 and the second switch Q2 respectively, the emitter of the first switch tube Q1 is coupled to the speaker K1, and the emitter of the second switch tube Q2 is coupled to the flashing light LED1. When the control end of the controller sends a low-level control signal to the first switch tube Q1 and the second switch tube Q2, the two switch tubes are turned on, and then the speaker and the flashing light are powered on and emit sound and light prompts.

[0032] The method of use is as follows: the user lies on the bed, places the calf on the calf support board 10, places the sole of the foot on the pedal 20, adjusts the distance between the calf support board 10 and the shell 30 according to the user's situation, and fixes the calf and the sole of the foot with a strap. Start ankle pump exercise (for example, plantar flexion). After being squeezed by the spring sheet 22, the two pressure sensors 31 send a sensing signal to the controller. The controller reads the pressure value through the sensing signal, and also calculates the duration of the sensing signal, compares the pressure value with the pressure threshold, and compares the duration with the time threshold. When both exceed the threshold, the control end of the controller outputs a control signal, and the speaker and flashing light send out sound and light prompts, ending one movement training. The next movement (for example, dorsiflexion) is also the same control process.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
