Description

Technical Field

[0001] The invention relates to the technical field of rehabilitation equipment, in particular to a posture and quantity monitoring device for ankle joint pump movements. Background Art

[0002] Ankle pump exercise, as an effective means of lower limb rehabilitation, is widely used to promote blood circulation in the lower limbs, prevent deep vein thrombosis, and enhance ankle joint flexibility and strength.

[0003] After the patient is given medication and routine care, ankle pump exercises should be performed, with both legs performed alternately or simultaneously, as shown in the attached figure of the instruction manual. Figure 1 As shown in the figure, the ankle pump exercise should be performed with the ankle joint as the center to do a 360° circle of the ankle joint, with the toes hooked upward to the maximum extent, facing oneself, and held for 3 to 5 seconds, and then the toes are stretched downward to the maximum extent, and held for 3 to 5 seconds. From the toe position a→b→a, it is counted as one set, and the amplitude during the period is 20 to 60°; the ankle pump exercise includes internal rotation and external rotation, and its operation is: one circle around the central axis of the toe position is counted as one time, and the ankle flexion and extension exercise is 3 to 4 times / day, 20 to 30 sets each time. However, in actual clinical treatment, the execution effect of this exercise is often affected by multiple factors, resulting in unsatisfactory rehabilitation effects, which are mainly reflected in the following aspects:

[0004] 1. The patient's ankle pump movement is not in place (for example, the maximum range of the patient's ankle pump movement is 50°, but the single range of motion is only 40° to 45°, and the patient does not maximally hook the toes up or stretch the toes down), or the patient does not maintain the position for 3 to 5 seconds after the movement is in place;

[0005] 2. The number of exercises is unclear. Patients often find it difficult to accurately record the number of exercises they do, which may lead to less or missed exercises.

[0006] 3. The patient's exercise frequency is too fast or too slow;

[0007] 4. The patient forgets to do it or is not very motivated.

[0008] The above are common situations for most patients, which will lead to poor rehabilitation effects and long recovery periods of affected parts, resulting in increased pain for patients. For this reason, technical personnel in this field have also proposed devices for assisting ankle joint movements, but they can often only count the flexion and extension ankle pump movements, while the equally important circumferential ankle pump movements cannot be monitored, which has obvious limitations. For this reason, we propose a posture and quantity monitoring device for ankle joint pump movements. Summary of the invention

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Embodiment 1:

[0042] See also Figure 1-12 The present invention provides a technical solution: a posture and quantity monitoring device for ankle pump movement, comprising a control terminal 1 and a bracket body 2, wherein the control terminal 1 is a display with a built-in compiler and is connected to the internal medical system of the hospital. This is a prior art, and a support belt 21 is installed on the bracket body 2 by bolts, and the support belt 21 has multiple strips and is linearly arrayed on the bracket body 2, and further comprises:

[0043] There are two mounting seats 3, which are fixed on both sides of the ends of the bracket body 2, and each mounting seat 3 is installed with a support plate 31;

[0044] The first rotating shaft 4 has the same number as the mounting seat 3, and is rotatably connected to the support plate 31 respectively, and is located on both sides of the patient's ankle position. A support rod 41 is sleeved on the first rotating shaft 4, and the support rod 41 and the first rotating shaft 4 are fixedly connected. A telescopic rod 42 is installed on each of the support rods 41, and a cross-axis universal joint 43 is fixed at one end of the telescopic rod 42 away from the support rod 41. A foot rest 44 is installed between the two cross-axis universal joints 43, and a hole 45 is opened on the foot rest 44. A restraint belt 46 is provided through the hole 45, and the restraint belt 46 is a Velcro type;

[0045] It should be noted that, for patients with smaller feet, a shoe insole or other protective pads made of skin-friendly materials can be added to the foot rest 44 so that the ankle portion of the patient is located between the first rotation axis 4 .

[0046] The conversion mechanism 5 is installed on the support rod 41. The conversion mechanism 5 is used to convert two moving trajectories of the footrest 44. One trajectory is to restrict the telescopic rod 42 and the cross-axis universal joint 43, restricting the footrest 44 to rotate around the first rotating shaft 4 as the center. In this state, the patient performs flexion and extension ankle pumping exercises. The other trajectory is to release the fixation of the cross-axis universal joint 43, allowing the footrest 44 to rotate with an angle. In this state, the patient performs circumferential ankle pumping exercises.

[0047] The first monitoring mechanism 6 is installed on the support plate 31 and is connected to the first rotating shaft 4 and is electrically connected to the control terminal 1. When the patient performs the ankle flexion and extension pump exercise, the first monitoring mechanism 6 records the maximum flexion and extension position performed by the patient, and when the patient performs the ankle flexion and extension pump exercise, the first monitoring mechanism 6 records the effective number of the patient's exercise;

[0048] The auxiliary mechanism 7 is installed on the first rotating shaft 4 and connected to the first monitoring mechanism 6. After the patient performs a single stretch and flexion ankle pump exercise, the auxiliary mechanism 7 limits the rotation of the support rod 41 to assist the patient in maintaining the exercise posture for 3 to 5 seconds;

[0049] The second monitoring mechanism 8 is installed on the bracket body 2 and is electrically connected to the control terminal 1. The second monitoring mechanism 8 records the trajectory of the patient's most standard ankle pump movement and records the effective number of times the patient moves when the patient performs the ankle pump movement.

[0050] The conversion mechanism 5 includes a first through hole 51 opened in the cross-axis universal joint 43, the telescopic rod 42 and the support rod 41. The first through hole 51 connects the side of the cross-axis universal joint 43 close to the footrest 44 to the side of the support rod 41 in the corresponding direction. Figure 7As shown, the part of the first through hole 51 located at the cross-axis universal joint 43 is square, and the other part is octagonal, a sealed cover 52 is fixed on one side of the support rod 41, and the sealed cover 52 seals one end of the first through hole 51. A limiting rod 53 is installed in the sealed cover 52, and an octagonal column 54 is installed through the first through hole 51. An air pump 55 is installed on the footrest 44, and an air pipe 56 is connected to the air pump 55. There are two air pipes 56, which are respectively connected to the sealed cover 52.

[0051] The outer periphery of the octagonal column 54 is wrapped with a rubber sleeve, and the top end is rounded.

[0052] The rubber sleeve makes the octagonal column 54 fit tightly against the inner wall of the first through hole 51. When the air pump 55 drives the octagonal column 54 to move, the position of the octagonal column 54 can be quickly and accurately controlled. The rounded corners on the top make it easier for the octagonal column 54 to pass through the center of the cross-axis universal joint 43, making it more convenient for the device to switch from the ankle pumping motion to the ankle pumping motion.

[0053] The first monitoring mechanism 6 includes an infrared receiving board 61 installed on the support plate 31 , and an infrared transmitter 62 is installed on the portion of the support rod 41 opposite to the support plate 31 . Both the infrared receiving board 61 and the infrared transmitter 62 are electrically connected to the control terminal 1 .

[0054] The auxiliary mechanism 7 includes an electromagnet 71 sleeved on the first rotating shaft 4, a frame 72 is relatively fixed on the first rotating shaft 4, a magnet bar 73 is arranged on the frame 72, a second through hole 74 is opened in the middle of the magnet bar 73, the magnet bar 73 is slidably connected with the frame 72 through the second through hole 74, a resistance increasing block 75 is arranged on the magnet bar 73, and the end of the resistance increasing block 75 away from the first rotating shaft 4 is arc-shaped, a cylindrical shell 76 is fixed on the support plate 31, the cylindrical shell 76 is located between the support plate 31 and the support rod 41, and cooperates with the support plate 31 and the support rod 41 to surround the infrared transmitter 62 and the infrared receiving plate 61.

[0055] A closed space is formed between the cylindrical shell 76, the support plate 31 and the support rod 41, which can prevent the infrared transmitter 62 and the infrared receiving plate 61 from dust accumulation on the one hand, and block external light on the other hand to prevent external light from interfering with the infrared rays in the space.

[0056] The second monitoring mechanism 8 includes an extension frame 81 installed on the bracket body 2, and a photosensitive plate 82 is fixed on the extension frame 81. A conical groove 83 is opened at the bottom end of the footrest 44, and a highlight lamp 84 is installed in the conical groove 83. The photosensitive plate 82 is located directly below the footrest 44, and the highlight lamp 84, the photosensitive plate 82, and the control terminal 1 are electrically connected.

[0057] The control terminal 1 is equipped with a remote control display 11. There are multiple remote control displays 11, and each of them is equipped with a speaker.

[0058] For older patients, remote control operation is more convenient than mobile phone operation. Patients can control the operation and conversion status of various components by pressing buttons on the remote control display 11.

[0059] Working principle: The control terminal 1 is directly connected to the medical system inside the hospital, so that patients and medical staff can intuitively and conveniently understand the patient's exercise status. After the patient is hospitalized, the personal information is directly recorded in the control terminal 1. The patient can scan the code with a mobile phone or insert the medical insurance card to receive the remote control display 11 that matches his or her own information. Then, under the guidance of the doctor, the patient can enter the best exercise that he or she can do through the device. The operation is as follows:

[0060] The patient places the calf on the support belt 21, with the sole of the foot fitting closely to the inner bottom surface of the foot support 44. The upper foot of the patient is then fixed to the foot support 44 by Velcro. The patient exerts force with his foot to make the sole of the foot as perpendicular to the bottom surface as possible. The rotation amplitude of the ankle flexion and extension pump movement will be different according to the different patient conditions. First, the learning button on the remote control display 11 is used to start the learning of the ankle flexion and extension pump movement, and the current rotation amplitude of the patient's ankle flexion and extension is recorded. In this state, the air pump 55 is turned on to continuously inject gas into the sealed cover 52. As the air pressure in the sealed cover 52 increases, the octagonal column 54 is pushed, and the octagonal column 54 moves in the first through hole 51, which is supported by the air pump 55. One end of the sealing cover 52 moves toward the footrest 44. During this process, even if the first through hole 51 located at the center of the cross-axis universal joint 43 is slightly misaligned with the octagonal column 54, as the octagonal column 54 moves, the cross-sectional area of ​​the rounded portion of the top of the octagonal column 54 is smaller than the cross-sectional area of ​​the rear half, and the rounded octagonal column 54 is easily inserted into the first through hole 51 of the cross-axis universal joint 43, and the edges of the octagonal column 54 cooperate with it, thereby limiting the cross-axis universal joint 43 from rotating in any direction. At this time, the footrest 44 can only rotate with the first rotating shaft 4 as the center through the cross-axis universal joint 43, the telescopic rod 42, and the support rod 41;

[0061] At the same time, the infrared transmitter 62 and the infrared receiving board 61 are turned on, and under the guidance of the medical staff, the patient curls his toes upward as much as possible and stays there for more than 3 seconds. At this time, the infrared receiving board 61 records the position, and then the patient curls his toes downward as much as possible. The infrared receiving board 61 records the new position again. At this time, the data recording of the patient's ankle flexion and extension pump movement is completed.

[0062] Later, when the patient needs to perform ankle flexion and extension pump exercise, the remote control display 11 is turned on to press the button of ankle flexion and extension pump exercise, and the equipment starts to monitor whether the patient's exercise posture is correct or not, as well as the amount of exercise, and the patient can perform the corresponding action. If the patient's action is not in place during the exercise, the recording point on the infrared receiving board 61 cannot correspond to the infrared transmitter 62, regardless of the number of times, and each time the correspondence occurs, the electromagnet 71 will be started to provide repulsive force to the magnet strips 73 on both sides of itself, and the magnet strips 73, under the guidance of the frame 72 and the second through hole 74, drive the resistance increasing block 75 at the top to The inner wall of the cylindrical shell 76 fits tightly, so that the rotation of the foot rest 44 is limited by the first rotating shaft 4, the support rod 41, the telescopic rod 42 and the cross-axis universal joint 43 after being limited. That is, each time the patient curls his toes upward or stretches his toes downward to the maximum extent, the device will provide assistance to keep it for more than 3 seconds. After 3 to 5 seconds, the electromagnet 71 is powered off and the patient can perform reverse movement again, thereby achieving a better treatment effect. When the patient finishes a single group, the remote control display 11 sends a reminder through the speaker, and the patient can perform ankle pump exercises or take a temporary rest according to his own situation.

[0063] The recording function of the ankle pump movement is turned on by pressing the button on the remote control display 11. In this state, the air pump 55 is turned on in the reverse direction. The air pump 55 is a dual-purpose filling and suction type, which is a prior art. The gas injected into the closed cover 52 is continuously extracted. As the air pressure in the closed cover 52 decreases, the octagonal column 54 moves in the reverse direction in the first through hole 51, and finally returns to the initial position and is blocked by the limit rod 53. The distance between the limit rod 53 and the side of the closed cover 52 away from the support rod 41 is the connection point between the trachea 56 and the closed cover 52, which prevents the octagonal column 54 from blocking the connection point. The cross-axis universal joint 43 without the restriction of the octagonal column 54 can rotate in any direction, and cooperates with the telescopic rod 42 to provide a certain lateral movement ability. At this time, the patient can perform the ankle pump movement;

[0064] At the same time, the highlight lamp 84 and the photosensitive plate 82 are turned on. Under the restriction of the conical groove 83, the light emitted by the highlight lamp 84 shines on the photosensitive plate 82. Under the guidance of the medical staff, the patient makes the most standardized movements by himself. At this time, an elliptical trajectory will be received on the photosensitive plate 82. The patient repeats three times or more and records the trajectory. At this time, the data recording of the patient's ankle pump movement is completed.

[0065] When the patient is performing ankle pump exercise, turn on the button of ankle pump exercise on remote control display 11, and the patient can do the exercise for recording. If the patient's movements are not in place during the exercise, and if the area received by the photosensitive plate 82 in a single movement of the patient is less than 80% of any recorded area, the area range can be set by the operating end of the medical staff. The above operation can be achieved through analysis software, such as finite element analysis, etc., and the number of times will not be counted. When the patient finishes a single group, the remote control display 11 sends a reminder through the speaker, and the patient can take a temporary rest or perform ankle pump exercise according to his or her own situation.

[0066] Medical staff can directly monitor whether the patient is exercising or whether the daily exercise volume meets the standard through the control terminal 1. Patients and their families can also understand by scanning the code, so as to remind and supervise the patients in certain time periods.

[0067] It should be noted that when the patient is performing ankle flexion and extension pump exercises, after the patient hooks the toes up or down to the maximum extent once, the auxiliary mechanism 7 will be triggered, and the control terminal 1 can calculate the frequency of the patient's ankle flexion and extension pump exercises according to the opening frequency of the electromagnet 71; when the patient is performing ankle circumferential pump exercises, the frequency of the patient's ankle circumferential pump exercises can also be calculated based on the time after a single rotation of the patient's ankle part; when the patient's exercise frequency is too fast or too slow, the speaker will issue a corresponding prompt to remind the patient to reduce or increase the frequency of exercise.

[0068] Embodiment 2:

[0069] Based on Example 1, this application further optimizes this solution:

[0070] The surface of the photosensitive plate 82 is coated with a nano-fluorocarbon coating.

[0071] The fluorocarbon coating has excellent weather resistance, corrosion resistance and self-cleaning properties. Its surface energy is low and it is not easily contaminated by dust and dirt. The nano coating has super hydrophobic and super oleophobic properties, which effectively prevents the adhesion of stains, making it more convenient to clean the photosensitive plate 82 and extending the service life of the photosensitive plate 82.

[0072] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
