Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a bed foot mobilizer after great saphenous vein surgery. Background Art

[0002] Varicose veins of the great saphenous vein is a common vascular disease. Due to venous valve insufficiency and weak venous walls, venous blood refluxes and accumulates, causing the veins to be tortuous and dilated. Patients often feel soreness, heaviness, and fatigue in the lower limbs. After standing for a long time, the ankles swell, and the superficial veins in the calves dilate, become tortuous, and bulge, which is more obvious when standing upright. The main purpose of great saphenous vein surgery is to remove or ligate the varicose great saphenous vein, prevent blood from flowing backward, and reduce the pressure on the lower limb veins, thereby relieving the symptoms caused by varicose veins in the lower limbs, such as swelling, pain, pigmentation, and ulcers.

[0003] After great saphenous vein surgery, the patient's blood is in a hypercoagulable state, and the blood flow in the lower limb veins is slow. If the patient does not move for a long time, deep vein thrombosis of the lower limbs is likely to form. At present, the main methods are to use elastic stockings and encourage patients to get out of bed and move around as soon as possible to promote venous return, reduce venous blood stasis, and prevent deep vein thrombosis. For the early postoperative period, especially for elderly patients, the amount of activity is less within 24 hours after surgery due to physical reasons. Therefore, the prior art discloses a large number of activity devices for use in bed to assist the patient's foot movement and promote venous return. For example, the announcement number CN207101426U discloses a great saphenous vein postoperative care device, including elastic stockings and a care seat, which promotes patients to do dorsiflexion and extension exercises through vertical plates, movable plates and springs, and measures the number and time of activities through a push-type counter and timer, so as to urge patients to perform rehabilitation exercises and improve the recovery effect.

[0004] However, there are currently few postoperative monitoring devices for the affected limbs, and medical staff mainly rely on regularly checking the color of the patient's toes on the affected limbs to make judgments: if the patient's toes are white, it may be due to insufficient blood supply to the limb arteries, resulting in blood not being able to be normally infused to the toes. At this time, it is necessary to check in time whether the elastic stockings are worn too tightly and cause compression of the arteries; if the toes are purple, it is likely that venous return is blocked and blood is accumulated at the end of the limb. This is usually an early signal of deep vein thrombosis. After the thrombus blocks the vein, venous blood cannot return smoothly, resulting in local blood accumulation, causing the toes to change color. At this time, timely intervention is needed.

[0005] However, the above monitoring method still has the following technical problems in actual use:

[0006] 1. Highly subjective: It is quite subjective for medical staff to observe the color of the patient's toes to judge whether there is a problem. Different medical staff may have different sensitivities and judgment standards for color changes. For example, the judgment of the degree of slight whiteness or purpleness may vary from person to person, which can easily lead to misjudgment or missed judgment.

[0007] 2. Untimely: Medical staff cannot always stay by the patient’s bedside to observe and can only check periodically. However, if the patient’s condition changes rapidly, such as deep vein thrombosis forming in a short period of time and causing serious blood congestion, the best time for intervention may be missed. Summary of the invention

[0008] The present invention is intended to provide a bed foot mobilization device for patients after great saphenous vein surgery, so as to solve the technical problem that the prior art cannot monitor the affected limb in a timely and effective manner after surgery.

[0009] In order to achieve the above object, the present invention adopts the following technical scheme:

[0010] A foot mobilization device for patients after great saphenous vein surgery, comprising a support, an auxiliary mechanism for assisting the patient's foot movement and a monitoring device for monitoring the patient's toes are arranged on the support, the support comprises a horizontally arranged support portion and a vertically arranged mounting portion, the auxiliary mechanism is arranged on the support portion, the monitoring device is arranged on the mounting portion, and a power supply for supplying power to the monitoring device is also arranged in the mounting portion;

[0011] The monitoring device includes a control system, a camera module electrically connected to the control system, and an alarm. The camera module includes a shooting unit and a recording unit. When initially used, the shooting unit first shoots a high-definition initial photo of the toe, and sends the initial photo to the control system for storage. After receiving the initial photo, the control system controls the recording unit to be in a recording state.

[0012] When the recording unit monitors that the color of the patient's toes has changed, a signal is sent to the control system. After receiving the signal, the control system controls the shooting unit to take a photo of the toes. The photo is a comparison photo. After receiving the comparison photo, the control system compares and analyzes it with the initial photo to determine whether it is abnormal. When the output result is an abnormal signal, the control system controls the alarm to sound an alarm. When the output result is a normal signal, the control system controls the camera module to adjust to the recording state.

[0013] Beneficial effects:

[0014] 1. By setting a monitoring device on the support, the color status of the patient's toes can be monitored in real time. When the toe color is abnormal, an alarm can be issued in time. Compared with the method of relying on medical staff to check regularly, the monitoring is more timely and objective, and it can also reduce the workload of medical staff and save medical resources.

[0015] 2. The camera module includes two modes: shooting and recording. During initial use, a high-definition photo is taken and stored in the control system for subsequent comparative analysis. Using the patient's own toe photos for before-and-after comparison is helpful to improve the accuracy of judgment. Even relatively small changes can be determined through photo comparison and analysis to determine whether the toe color has changed, such as whether it has turned white or purple compared to the initial photo, which is helpful to detect abnormal situations in time and intervene.

[0016] 3. The recording unit is usually in recording state, monitoring the toes on the affected limb side in real time. When an abnormality occurs in the monitoring, a signal is sent to the control system. The control system controls the shooting unit to take a high-definition comparison photo and sends it to the control system. The control system analyzes the initial photo and the comparison photo and outputs the result. If the output result is an abnormality, the alarm is controlled to alarm. If the output result is normal, it switches to recording state to continue monitoring. This method can further improve the accuracy of the output results and avoid misjudging the monitoring as abnormal due to light or changes in patient position.

[0017] 4. By setting up auxiliary mechanisms on the support part, it can be used to assist patients in foot activities, such as assisting in foot flexion and extension exercises. Compared with relying entirely on active training by patients, the auxiliary mechanisms can increase the enthusiasm and frequency of patients' activities and reduce the difficulty of activities, thereby effectively promoting venous return, reducing venous blood congestion, and preventing deep vein thrombosis.

[0018] Preferably, as an improvement, a light source is also provided on the mounting portion, the light source is electrically connected to the control system, the light source is arranged below the camera module through a rotating member, the position of the light source is adjusted by the rotating member, and the light source is irradiated toward the sole of the foot.

[0019] Beneficial effect: The rotating part is provided to help adjust the irradiation angle of the light source, so that the light source can effectively irradiate the sole of the foot, which is beneficial to improving the clarity of shooting.

[0020] Preferably, as an improvement, an L-shaped support frame is provided at one end of the support portion away from the mounting portion, the support frame and the support portion form a limiting space, and a start switch is also provided on the inner side of the support frame, the start switch is electrically connected to the power supply, and is used to start the monitoring device.

[0021] Beneficial effect: By arranging the start switch on the inner side of the support frame, when the patient puts the affected limb into the limited space formed by the support frame and the support part, the start switch can be pressed to start the monitoring device.

[0022] Preferably, as an improvement, a mounting plate is vertically provided on the top of the support frame, the plate surface of the mounting plate is arranged parallel to the mounting portion, and a mirror is provided on the side of the mounting plate close to the mounting portion; when the patient removes the affected limb from the support, the light source shines on the mirror surface and forms a light spot on the mirror surface, and when the camera module captures the light spot, a signal is sent to the control system, and the control system controls the camera module circuit to disconnect.

[0023] Beneficial effects: When the patient's affected limb is placed on the support, the mirror surface will be blocked. At this time, the camera module cannot capture the light spot of the light source in the mirror surface. The light source plays a lighting role, which can improve the clarity of the shooting; when the patient gets out of bed or is not in the bed, the affected limb leaves the support. At this time, the light source directly shines on the mirror surface and forms a light spot. The camera module captures the light spot and sends a signal to the control system, and the control system controls the camera module circuit to disconnect.

[0024] Using the above method to turn off the camera module is beneficial to improving accuracy and reducing the camera module shutdown caused by accidental touch, especially when the patient changes his position or performs foot movements. As long as the foot has not completely left the support, the mirror surface will be blocked and the camera module cannot capture the light spot in the mirror surface. Therefore, using the above method can not only automatically turn off the camera module when the patient leaves the bed, but also improve the accuracy of the shutdown and reduce accidental touches and accidental shutdowns.

[0025] Preferably, as an improvement, the control system also includes an education module and a training module, and the training module is used to customize a training plan according to the patient's physical condition and the state of the affected limb.

[0026] Beneficial effects: Setting up training modules is conducive to customizing exercise plans according to the patient's personal conditions, such as customizing exercise duration, exercise frequency, etc.

[0027] Preferably, as an improvement, a display screen is provided on one side of the mounting plate away from the mounting portion, the display screen is electrically connected to the control system, and the display screen is used to display the training plan or for education.

[0028] Beneficial effects: The position setting of the display screen makes it convenient for the patient to view the contents on the display screen while lying on his back in bed, such as training according to the training plan on the display screen, or viewing the rehabilitation knowledge preached on the display screen.

[0029] Preferably, as an improvement, the auxiliary mechanism includes a push rod, a rocker and a foot rest arranged on the rocker, a mounting groove is arranged on the supporting portion of the support, the bottom end of the rocker is movably arranged in the mounting groove, and the top of the rocker extends out of the mounting groove; the push rod is arranged in the mounting groove, the power output end of the push rod is movably connected to the rocker, and the push rod is used to drive the rocker to swing back and forth; the foot rest is used to support the heel and limit the heel.

[0030] Beneficial effect: When the patient needs to perform flexion and extension exercises on the foot, the push rod is started, and the push rod is used to push the rocker to swing, thereby assisting the patient in performing the flexion and extension exercises.

[0031] Preferably, as an improvement, a spring is further provided in the mounting groove, and the spring is arranged opposite to the push rod.

[0032] Beneficial effect: The spring is provided to play a certain buffering role, which is helpful to reduce the swing intensity of the rocker and avoid injury to the ankle during the activity.

[0033] Preferably, as an improvement, the push rod is electrically connected to the control system, and the push rod is a cylinder.

[0034] Beneficial effects: The working parameters of the push rod can be adjusted through the control system, and the push rod action can be started within the set time to assist the patient in foot activities. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following is further described in detail through specific implementation methods:

[0040] The figure marks in the drawings of the specification include: support 1, support part 11, mounting part 12, mounting groove 13, auxiliary mechanism 2, rocker 21, push rod 22, footrest 23, spring 24, control system 3, camera module 31, light source 32, universal joint 321, alarm 33, storage module 34, result analysis module 35, training module 36, education module 37, support frame 4, start switch 41, mounting plate 5, mirror 51, protrusion 511, groove 512, display screen 6.

[0041] Embodiment 1

[0042] like Figure 1-2As shown, the foot mobilization device for patients after great saphenous vein surgery includes a support 1, on which is provided an auxiliary mechanism 2 for assisting the patient's foot movement and a monitoring device for monitoring the patient's toes. The support 1 includes a horizontally arranged support portion 11 and a vertically arranged mounting portion 12. The auxiliary mechanism 2 is arranged on the support portion 11, and the monitoring device is arranged on the mounting portion 12. The mounting portion 12 is also provided with a power supply (not shown in the figure) for powering the monitoring device. The power supply is a rechargeable battery, and the support 1 is also provided with a power cord for charging the battery. Specifically, in this embodiment, the support portion 11 has a certain height. When the patient's affected limb is placed on the support portion 11, it has a certain lifting effect on the affected limb, which is beneficial to venous return, reducing swelling and relieving pain.

[0043] The monitoring device includes a control system 3 and a camera module 31 and an alarm 33 electrically connected to the control system 3. The camera module 31 includes a shooting unit and a recording unit. When initially used, the shooting unit first takes a high-definition initial photo of the toes, and sends the initial photo to the control system 3 for storage. After receiving the initial photo, the control system 3 controls the recording unit to be in a recording state; when the recording unit monitors that the color of the patient's toes has changed, a signal is sent to the control system 3. After receiving the signal, the control system 3 controls the shooting unit to take a photo of the toes, which is a comparison photo. After receiving the comparison photo, the control system 3 compares and analyzes it with the initial photo to determine whether it is abnormal; when the output result is an abnormal signal, the control system 3 controls the alarm 33 to alarm, and when the output result is a normal signal, the control system 3 controls the camera module 31 to adjust to the recording state.

[0044] Specifically, the control system 3 is provided with a storage module 34 and a result analysis module 35. The storage module 34 is used to store the photographed photos or recorded videos, and send the stored photos to the result analysis module 35; the result analysis module 35 is used to compare and analyze the initial photos and the comparison photos taken subsequently, and output the result of whether there is an abnormality. Specifically, the analysis method of the result analysis module 35 for whether the color of the toes in the photo has changed is an existing technology, for example, the existing method based on color space threshold, the method based on feature points or the method based on deep learning can be used for analysis.

[0045] The camera module 31 uses an existing smart camera with shooting and video recording functions. It is electrically connected to the control system 3. The control system 3 is used to control the smart camera to be in recording or shooting state. The smart camera has built-in image recognition and analysis functions, and can be monitored by setting specific color thresholds and areas, thereby achieving preliminary color abnormality judgment. For example, by adopting the existing fixed threshold method, the threshold range of the color space such as RGB or HSV of the normal color of the toes is determined in advance. During the recording process, the color value of the pixels in the toe area in each frame of the image is extracted to determine whether it exceeds the normal threshold range; if it exceeds, the signal is sent to the control system 3, and the control system 3 controls the smart camera to take pictures of the toes, and further analyzes through the result analysis module 35 to output the final judgment result; if it does not exceed, it continues to be in the monitoring state.

[0046] like Figure 1 As shown, a light source 32 is also provided on the mounting portion 12, and the light source 32 is electrically connected to the control system 3. The light source 32 is arranged below the camera module 31 through a rotating member, and the position of the light source 32 is adjusted by the rotating member. The light source 32 is irradiated toward the sole of the foot, and is used to fill in light on one side of the sole of the foot, which is beneficial for the camera module 31 to clearly take photos of the toes; specifically, the rotating member in this embodiment adopts a universal joint 321, and the angle of the light source 32 is adjusted by rotating the universal joint 321.

[0047] An L-shaped support frame 4 is also provided at one end of the support portion 11 away from the mounting portion 12. The support frame 4 and the support portion 11 form a limited space. A start switch 41 is also provided on the inner side of the support frame 4. The start switch 41 is electrically connected to a power supply and is used to start the monitoring device. By setting the start switch 41 on the inner side of the support frame 4, when the patient puts the affected limb into the limited space formed by the support frame 4 and the support portion 11, the start switch 41 can be pressed to start the monitoring device, thereby starting the operation of the monitoring device and monitoring the toe color of the affected limb in real time.

[0048] A mounting plate 5 is vertically arranged on the top of the support frame 4, and the plate surface of the mounting plate 5 is arranged parallel to the mounting portion 12. A mirror 51 is arranged on the side of the mounting plate 5 close to the mounting portion 12. In this embodiment, the mirror 51 is a reflector. When the patient removes the affected limb from the support 1, the light source 32 is irradiated on the mirror 51 and a light spot is formed on the mirror 51. When the camera module 31 captures the light spot, a signal is sent to the control system 3. After receiving the signal, the control system 3 controls the circuit of the camera module 31 to disconnect.

[0049] When the patient's affected limb is placed on the support 1, the mirror 51 will be blocked. At this time, the camera module 31 cannot capture the light spot of the light source 32 in the mirror 51. The light source 32 plays a lighting role, which can improve the clarity of the shooting; when the patient gets out of bed or is not in the bed, the affected limb leaves the support 1. At this time, the light source 32 directly shines on the mirror 51 and forms a light spot. The camera module 31 captures the light spot and sends a signal to the control system 3. The control system 3 is used to control the circuit of the camera module 31 to disconnect.

[0050] The above-mentioned method for closing the camera module 31 is beneficial to improving accuracy and reducing the closing of the camera module 31 caused by accidental touch, especially when the patient changes his position or performs foot movements. As long as the foot has not completely left the support 1, the mirror 51 will be partially blocked, so that the camera module 31 cannot capture the light spot in the mirror 51; therefore, the above-mentioned method can not only automatically close the camera module 31 when the patient leaves the bed, but also improve the closing accuracy and reduce accidental touch and accidental closing.

[0051] The control system 3 also includes an education module 37 and a training module 36. The training module 36 is used to customize a training plan according to the patient's physical condition and the state of the affected limb, for example, to customize the exercise duration, exercise frequency, etc. according to the patient's personal situation; a display screen 6 is provided on the side of the mounting plate 5 away from the mounting portion 12. The display screen 6 is electrically connected to the control system 3. The display screen 6 is used to display the training plan or for education; the display screen 6 is set in a position that is convenient for the patient to view the content on the display screen 6 when lying on his back on the bed, for example, to perform activities according to the training plan on the display screen 6, or to watch the rehabilitation knowledge preached on the display screen 6.

[0052] When in use, the patient extends the affected limb into the limited space of the support part 11, and touches and presses the start switch 41 to connect the circuit and start the monitoring device; the camera module 31 first takes a high-definition photo of the toes and stores it in the control system 3, which is convenient for subsequent comparative analysis. Using the patient's own toe photos for before and after comparison is beneficial to improve the accuracy of judgment. Even if it is a relatively small change, it can be determined through photo comparison and analysis whether the toe color has changed, for example, whether it has become white or purple compared to the initial photo, which is conducive to timely detection of abnormal conditions and intervention.

[0053] After the shooting is completed, the camera module 31 monitors the toes on the affected limb side in real time. When the monitoring is abnormal, the signal is sent to the control system 3. The control system 3 controls the shooting unit to take a high-definition comparison photo and sends it to the control system 3. The control system 3 analyzes the initial photo and the comparison photo and outputs the result. If the output result is an abnormality, the alarm 33 is controlled to alarm. If the output result is normal, it switches to the recording state to continue monitoring. The present invention can analyze possible abnormal situations twice, which is beneficial to further improve the accuracy of the output results and avoid misjudging the monitoring as abnormal due to reasons such as light or patient position changes.

[0054] When the patient gets out of bed, his / her affected limb leaves the support 1. At this time, the light source 32 directly shines on the mirror 51 and forms a light spot. The camera module 31 captures the light spot and sends a signal to the control system 3. The control system 3 controls the camera module 31 to disconnect the circuit. In this way, the camera module 31 can be automatically turned off when the patient leaves the bed, and the accuracy of the shutdown can be improved, reducing accidental touches and accidental shutdowns.

[0055] Embodiment 2

[0056] The difference between this embodiment and the first embodiment is that Figure 3 As shown, the auxiliary mechanism 2 includes a push rod 22, a rocker 21 and a foot rest 23 arranged on the rocker 21. A mounting groove 13 is arranged on the support portion 11 of the support 1. The bottom end of the rocker 21 is hingedly arranged in the mounting groove 13, and the top of the rocker 21 extends out of the mounting groove 13; the push rod 22 is arranged in the mounting groove 13, and the power output end of the push rod 22 is hinged to the rocker 21. The push rod 22 is used to drive the rocker 21 to swing back and forth; the foot rest 23 is used to support the heel and limit the heel.

[0057] Specifically, in this embodiment, the push rod 22 is a cylinder, which is electrically connected to the control system 3. The control system 3 can adjust the working parameters of the push rod 22, and start the push rod 22 to move within a set time to assist the patient in foot activities. More preferably, in this embodiment, a spring 24 is also provided in the mounting groove 13, and the spring 24 is arranged opposite to the push rod 22. The spring 24 plays a certain buffering role, which is conducive to reducing the swing strength of the rocker 21 and avoiding damage to the ankle during the activity.

[0058] When the patient needs to perform foot activities, the control system 3 controls the movement of the cylinder, and the cylinder pushes the rocker 21 to swing according to a predetermined extension and retraction frequency, thereby assisting the patient's foot to flex and extend. Compared with relying entirely on active training by the patient, the auxiliary mechanism 2 can increase the patient's enthusiasm and frequency of activities, reduce the difficulty of activities, thereby effectively promoting venous return, reducing venous blood congestion, and preventing deep vein thrombosis.

[0059] Embodiment 3

[0060] The difference between this embodiment and the second embodiment is that the mirror surface 51 is adjustably arranged on the mounting plate 5; Figure 4 As shown, a protrusion 511 is bonded to the back of the mirror 51, and a plurality of grooves 512 are provided on the mounting plate 5, and the grooves 512 are arranged along the vertical direction, and the protrusion 511 is used to be inserted into the grooves 512. More preferably, the protrusion 511 is made of elastic silicone or rubber, and the protrusion 511 is arranged in the middle of the back of the mirror 51. When in use, according to the length of the patient's instep, the protrusion 511 is inserted into the groove 512 of the corresponding height and tightened to adjust the height of the mirror 51, so as to flexibly adjust the mirror 51 according to the light source 32 or the patient's foot, so that when the patient's foot is placed on the support part 11, the mirror 51 can be better shielded, and when the patient's foot is removed, the light source 32 is reflected in the mirror 51 to form a light spot, further improving the accuracy of detection.

[0061] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
