Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a postoperative bed foot exerciser for great saphenous vein. BACKGROUND

[0002] Varicose veins of the great saphenous vein is a common vascular disease. Due to insufficient function of the venous valve, weakness of the venous wall and other reasons, the venous blood refluxes and accumulates, causing the vein to be tortuous and dilated. Patients often feel lower limb soreness, heaviness, fatigue, swelling of the ankle after standing for a long time, and the superficial veins of the lower leg are dilated, tortuous, clustered and raised, 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 to prevent blood from flowing backward and reduce the pressure of the lower limb veins, thereby relieving the symptoms caused by varicose veins of the lower limb, such as swelling, pain, pigmentation and ulceration.

[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, it is easy to form deep vein thrombosis in the lower limb. At present, the main method is to use elastic stockings and encourage the patient to get out of bed early to promote venous return and 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 many activity devices for use on the bed to assist the patient in moving the feet and promote venous return. For example, the announcement number CN207101426U discloses a great saphenous vein postoperative nursing device, which comprises an elastic stocking and a nursing seat. The patient's foot dorsiflexion and extension movement is promoted by a vertical plate, a movable plate and a spring. The number of activities and the time are measured by a press type counter and a timer to facilitate the patient's rehabilitation exercise and improve the recovery effect.

[0004] However, there are few postoperative monitoring devices for the affected limb at present, and the main method is for medical staff to check the color of the patient's toes on the affected limb at regular intervals to determine whether the patient's toes are white, which may indicate insufficient arterial blood supply to the limb, resulting in blood not being able to normally perfuse the toe, in which case the elastic stocking needs to be checked in time to determine whether it is too tight and is compressing the artery. If the toes are purple, it is likely that the venous return is blocked and the blood is accumulated at the end of the limb, which is usually an early sign of deep vein thrombosis. Because the thrombus blocks the venous return, the venous blood cannot flow back smoothly, causing the color of the toes to change, and intervention is needed in time.

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

[0006] 1. Highly subjective: Medical staff's judgment of whether there is a problem by observing the color of the patient's toes is relatively subjective. Different medical staff may have different sensitivities and judgment standards for color changes. For example, the judgment of the degree of slight whitening or purple may vary from person to person, which can easily lead to misjudgment or omission.

[0007] 2. Delay: Medical staff cannot stay at the patient's bedside to observe them all the time. They can only check on them periodically. However, in cases where the condition changes rapidly, such as deep vein thrombosis forming in a short period of time and causing severe blood stasis, the best time for intervention may be missed. Summary of the Invention

[0008] The present invention aims to provide a bed-mounted foot movement device after great saphenous vein surgery, in order to solve the technical problem that existing technologies cannot monitor the affected limb in a timely and effective manner after surgery.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A foot movement device for patients after great saphenous vein surgery includes a support, an auxiliary mechanism for assisting the patient's foot movement and a monitoring device for monitoring the patient's toes. The support includes a horizontally arranged support part and a vertically arranged mounting part. The auxiliary mechanism is arranged on the support part and the monitoring device is arranged on the mounting part. The mounting part also contains a power supply for powering the monitoring device.

[0011] The monitoring device includes a control system and a camera module and an alarm that are electrically connected to the control system. The camera module includes a shooting unit and a recording unit. When used for the first time, the shooting unit first takes 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 enter the recording state.

[0012] When the recording unit detects a change in the color of the patient's toes, it sends a signal to the control system. Upon receiving the signal, the control system controls the camera unit to take a picture of the toes. This picture serves as a comparison picture. After receiving the comparison picture, the control system compares and analyzes it with the initial picture to determine if there is any abnormality. When the output result is an abnormal signal, the control system activates the alarm. When the output result is a normal signal, the control system controls the camera module to switch to recording mode.

[0013] Beneficial effects:

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

[0015] 2、The camera module includes two modes of shooting and recording, and when initially used, a high-definition photo is stored in the control system, facilitating subsequent comparison and analysis, and the patient's own toe photo is used for comparison, which is beneficial to improve the accuracy of judgment, and even small changes can be judged by photo comparison and analysis, for example, whether the color of the toe changes, such as becoming white or purple compared to the initial photo, which is beneficial to timely discover abnormal conditions and intervene.

[0016] 3、The recording unit is in a video recording state at ordinary times, and the toes on the affected limb side are monitored in real time, and when an abnormality occurs in the monitoring, a signal is sent to the control system, the control system controls the shooting unit to shoot 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 abnormal, the control alarm is alarmed, and if the output result is normal, it is switched to the recording state to continue monitoring; this way can further improve the accuracy of the output result and avoid misjudgment of abnormality due to light or patient changing body position.

[0017] 4、By setting an auxiliary mechanism on the support part, the patient can be assisted in foot movement, such as assisting in foot flexion and extension movement, compared to completely relying on the patient's active training, the auxiliary mechanism can improve the patient's activity enthusiasm and activity frequency, and reduce the activity difficulty, thereby effectively promoting venous return, reducing venous blood stasis, and preventing deep vein thrombosis.

[0041] Embodiment one

[0042] As Figures 1-2As shown, the post-saphenous vein surgery bed foot mobilizer comprises a support 1, an auxiliary mechanism 2 for assisting the patient's foot movement and a monitoring device for monitoring the patient's toes are arranged on the support 1, the support 1 comprises a horizontally arranged support part 11 and a vertically arranged mounting part 12, the auxiliary mechanism 2 is arranged on the support part 11, and the monitoring device is arranged on the mounting part 12, and a power supply (not shown in the figure) for supplying power to the monitoring device is further arranged in the mounting part 12, the power supply is a rechargeable battery, and the support 1 is further provided with a power line for charging the battery. Specifically, the support part 11 has a certain height in the embodiment, when the patient's affected limb is placed on the support part 11, the affected limb is lifted to a certain height, which is beneficial to venous return, reduces swelling and relieves pain.

[0043] The monitoring device comprises a control system 3, a camera module 31 and an alarm 33 electrically connected to the control system 3, the camera module 31 comprises a shooting unit and a recording unit, when initially used, the shooting unit first shoots 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 changes, a signal is sent to the control system 3, after receiving the signal, the control system 3 controls the shooting unit to shoot 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 photos or videos shot, and sends the stored photos to the result analysis module 35; the result analysis module 35 is used to compare and analyze the initial photo and the comparison photo shot subsequently, and outputs the result whether it is abnormal. Specifically, the analysis method of the result analysis module 35 whether the color of the toes in the photo changes is prior art, for example, the existing color space threshold-based method, feature point-based method or deep learning-based method can be used for analysis.

[0045] The camera module 31 adopts an existing intelligent camera, has a shooting and recording function, is electrically connected with the control system 3, and controls the intelligent camera to be in a recording state or a shooting state by using the control system 3. The intelligent camera is internally provided with an image recognition and analysis function, can be monitored by setting a specific color threshold and area, and thus realizes preliminary color abnormality judgment. For example, by using an existing fixed threshold method, a threshold range of an RGB or HSV color space of a normal color of a toe is determined in advance. In the recording process, the color value of the pixels in the toe area of each frame of image is extracted, and it is judged whether the color value exceeds the normal threshold range. If the color value exceeds the normal threshold range, a signal is sent to the control system 3, the control system 3 controls the intelligent camera to take a photo of the toe, and the result analysis module 35 further analyzes and outputs a final judgment result. If the color value does not exceed the normal threshold range, the monitoring state is continued.

[0046] As shown in Figure 1 The mounting portion 12 is further provided with a light source 32, the light source 32 is electrically connected with the control system 3, the light source 32 is arranged below the camera module 31 through a rotating piece, the position of the light source 32 is adjusted through the rotating piece, the light source 32 is irradiated towards the direction of the sole, is used for supplementing light on the side of the sole, and is beneficial to the camera module 31 to clearly shoot a toe photo. Specifically, in the embodiment, the rotating piece adopts a universal joint 321, and the angle of the light source 32 is adjusted by rotating the universal joint 321.

[0047] The end of the supporting portion 11 away from the mounting portion 12 is further provided with an L-shaped support frame 4, the support frame 4 and the supporting portion 11 form a limiting space, the inner side of the support frame 4 is further provided with a starting switch 41, the starting switch 41 is electrically connected with the power supply, and is used for starting the monitoring device; by arranging the starting switch 41 on the inner side of the support frame 4, when the patient puts the affected limb into the limiting space formed by the support frame 4 and the supporting portion 11, the starting switch 41 can be pressed, and then the monitoring device is started to work, and the color of the toe of the affected limb is monitored in real time.

[0048] The top of the support frame 4 is vertically provided with a mounting plate 5, the plate surface of the mounting plate 5 is parallelly arranged with the mounting portion 12, one side of the mounting plate 5 close to the mounting portion 12 is provided with a mirror surface 51, and the mirror surface 51 adopts a mirror in the embodiment. When the patient takes the affected limb off the support 1, the light source 32 is irradiated on the mirror surface 51 and forms a light spot on the mirror surface 51. When the camera module 31 captures the light spot, a signal is sent to the control system 3, and the control system 3 controls the camera module 31 circuit to be disconnected after receiving the signal.

[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 role of illumination, which can improve the clarity of the shooting; when the patient gets out of bed or is not on the bed, the affected limb leaves the support 1, at this time the light source 32 directly irradiates 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 be disconnected.

[0050] The above-mentioned way of closing the camera module 31 is conducive to improving the accuracy and reducing the closing of the camera module 31 caused by accidental touch. Especially when the patient changes the body position or performs foot movement, as long as the foot is not completely away from the support 1, it will have a part of the mirror 51 blocked, so that the camera module 31 cannot capture the light spot in the mirror 51. Therefore, the above-mentioned way can automatically close the camera module 31 when the patient leaves the bed, and can improve the accuracy of closing, and reduce accidental touch and accidental closing.

[0051] The control system 3 further comprises a propaganda 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 movement time, movement frequency and the like according to the patient's individual situation; the display screen 6 is arranged on the side of the mounting plate 5 away from the mounting portion 12, the display screen 6 is electrically connected with the control system 3, and the display screen 6 is used to display the training plan or for propaganda; the display screen 6 is arranged at a position convenient for the patient to view the content on the display screen 6 when lying on the bed, for example, to carry out activities according to the training plan on the display screen 6, or to watch the rehabilitation knowledge on the display screen 6.

[0052] In use, the patient stretches the affected limb into the limiting space of the support portion 11 and touches and presses the starting switch 41 to turn on 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 comparison and analysis, and the patient's own toe photo is used for comparison and analysis, which is conducive to improving the accuracy of judgment, even if the change is small, the color change of the toes can be judged through photo comparison and analysis, for example, whether it is white or purple compared with the initial photo, which is conducive to timely discovering abnormal conditions and intervening.

[0053] After the shooting is completed, the camera module 31 monitors the toes of the affected limb in real time, and when an abnormality occurs in the monitoring, a signal is sent to the control system 3, the control system 3 controls the shooting unit to shoot a high-definition contrast photo and sends it to the control system 3, the control system 3 analyzes the initial photo and the contrast photo and outputs the result, if the output result is abnormal, the control alarm 33 alarms, and if the output result is normal, it switches to the recording state and continues to monitor; the application can analyze the possible abnormal situation twice, which is beneficial to further improve the accuracy of the output result and avoid misjudgment of the monitoring as abnormal due to light or change of the patient's body position.

[0054] When the patient gets off the bed, the affected limb leaves the support 1, at this time the light source 32 directly irradiates on the mirror surface 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 circuit to be disconnected; by using this way, the camera module 31 can be automatically turned off when the patient leaves the bed, and the accuracy of turning off can be improved, and the false touch and false off can be reduced.
