Description

Technical Field

[0001] The present invention relates to the technical field of postoperative rehabilitation nursing devices for tumors, and particularly relates to a postoperative rehabilitation nursing device for tumors. Background Art

[0002] After gynecological tumor surgery, patients need to actively carry out rehabilitation nursing work in order to reduce the occurrence of complications. Deep vein thrombosis complications often easily occur after existing gynecological tumor surgeries. The reasons are as follows: First, venous wall injury. Surgical operations may damage the venous wall, exposing the collagen under the vascular endothelium, thereby promoting the activation of platelets and coagulation factors, leading to thrombus formation. Second, slow blood flow. During the surgical process, patients lie in bed for a long time, and anesthesia causes relaxation of the lower limb muscles and dilation of the peripheral veins, further slowing down the blood flow rate. Third, hypercoagulable state of the blood. The scope of gynecological tumor surgery is large and the operation is complex, which may cause the body to be in a stress state, and tumor cells themselves may release thrombin-like substances, making the blood in a hypercoagulable state and increasing the risk of thrombus formation. Fourth, blood transfusion and indwelling venous access: Operations such as blood transfusion and indwelling central venous access after surgery may increase the risk of blood infection or injury, thereby triggering thrombus formation.

[0003] In order to avoid deep vein thrombosis after gynecological tumor surgery, doctors often recommend that patients be able to move as early as possible after surgery, and an effective way to reduce the probability of deep vein thrombosis without strenuous exercise is to perform ankle pump exercises. Ankle pump exercises are a more suitable way for gynecological tumor patients to exercise after surgery. The reasons why ankle pump exercises can prevent the formation of deep vein thrombosis are mainly as follows: First, accelerate blood flow in the lower limb veins: Ankle pump exercises make the soleus muscle and tibialis anterior muscle of the calf contract and relax regularly through the flexion and extension and circumduction movements of the ankle joint, thus playing a role similar to a pump, accelerating blood flow in the lower limb veins and relieving the state of blood stasis. Second, increase blood flow rate: The three main factors for thrombus formation are slow blood flow, hypercoagulable blood, and damaged vascular endothelial cells. Ankle pump exercises mainly prevent the occurrence of deep vein thrombosis (DVT) in the lower limbs by increasing the blood flow rate and promoting blood circulation. Third, strengthen muscle strength and avoid muscle atrophy: Ankle pump exercises can also strengthen the strength of the muscles around the ankle joint and avoid muscle atrophy caused by long-term bed rest or sitting.

[0004] Ankle pump exercises include flexion and extension exercises and circumduction exercises. The flexion and extension exercises are to lie flat on the bed or sit on a chair, straighten the legs, relax the feet, hook the toes as far up as possible to make the instep and calf form the largest angle, feel the stretching of the muscles on the back of the calf, and then step on the toes as far down as possible to lift the heels as much as possible, feeling the contraction of the muscles on the front of the calf. The circumduction exercise is to twist the ankle joint clockwise or counterclockwise.

[0005] However, the existing ankle pump exercises for patients are mostly self-initiated movements. After surgery, patients are physically weak and do not have enough strength to exercise, so the cooperation is generally poor. At present, there is no device that can assist tumor patients after surgery to perform ankle pump exercises. Based on the above situation, it is necessary to design a postoperative rehabilitation nursing device for tumors to assist patients in performing ankle pump exercises, so as to achieve the nursing of gynecological tumor patients after surgery. Summary of the Invention

Detailed implementation manners

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below with reference to specific drawings.

[0022] Ankle pump exercises include flexion and extension exercises and circumduction exercises. For the flexion and extension exercises, lie flat on the bed or sit on a chair with both legs straight and feet relaxed. Hook the toes upward as much as possible to make the dorsal side of the foot form the largest angle with the calf and feel the stretching of the muscles on the back of the calf. Then, step on the toes downward as much as possible to lift the heels as much as possible and feel the contraction of the muscles on the front of the calf. The circumduction exercise is to twist the ankle joint clockwise or counterclockwise. For patients after gynecological tumor surgery, deep vein thrombosis may easily occur during the postoperative rehabilitation period due to damaged venous walls, slow blood flow, or hypercoagulable blood. Ankle pump exercises can accelerate blood flow, enhance muscle strength, and prevent muscle atrophy, thereby reducing the problem of deep vein thrombosis in existing patients after gynecological tumor surgery during the rehabilitation period. Currently, there is a lack of devices on the market that can assist gynecological tumor patients in performing ankle pump exercises. Moreover, patients after gynecological tumor surgery are often physically weak and do not have enough strength to exercise, so their compliance is generally poor. Based on this situation, a postoperative rehabilitation nursing device for tumors is needed to assist patients in performing ankle pump exercises, thereby realizing the postoperative nursing of gynecological tumor patients.

[0023] The present invention provides a postoperative rehabilitation nursing device for tumors as Figure 1 shown. It includes a base 1, a slide rail 2, a linear drive assembly 3, a seat posture maintainer with adjustable height, and a controller 12. Among them, a bundling member is provided on the base 1 for fixing the user's feet. The slide rail 2 horizontally arranged below the base 1 is slidably connected to the base 1, which is used to carry the base 1 and guide the sliding direction of the base 1. The linear drive assembly 3 is used to provide the power for the base 1 to slide, so that the base 1 can perform linear reciprocating sliding along the slide rail 2. The controller 12 is used to control the operation of the linear drive assembly 3. The seat posture maintainer is used to maintain the user in a stable sitting posture. Specifically, when in use, after the user maintains a stable sitting posture at an appropriate height through the seat posture maintainer, the feet are respectively fixed on the two bases 1 by the bundling member. The controller 12 controls the linear drive assembly 3 to act, and the linear drive assembly 3 drives the feet on the base 1 to perform reciprocating linear motion along the slide rail 2. The user's upper body and thighs are always supported by the seat posture maintainer to maintain a relatively stable state, while the feet are driven by the base 1 to perform reciprocating linear motion along the slide rail 2. Therefore, the user's ankle joint can perform flexion and extension exercises, realizing the flexion and extension exercises of the user's ankle joint and knee joint. It should be noted that the seat posture maintainer with adjustable height can be composed of a seat 401 with a height-adjustable foot 402, and the bundling member can be composed of a foot receiving shell 5 and a bundling belt 501 on the foot receiving shell 5.

[0024] Since the ankle pump movement also has a circumferential movement of the ankle joint twisting clockwise or counterclockwise, in order for the above-mentioned postoperative tumor rehabilitation nursing device to achieve circumferential movement on the basis of the above-mentioned scheme, the base 1 should have a shaking function to achieve the circumferential movement of the ankle joint. Specifically, the base 1 includes an upper base plate 101 and a lower base plate 102. The lower base plate 102 is in sliding contact with the slide rail 2. The binding parts are arranged on the upper surface of the upper base plate 101. The lower surface of the upper base plate 101 and the upper surface of the lower base plate 102 are connected by a ball head rod 103 and a ball socket rod 104 to achieve a ball and socket connection, so that the upper base plate 101 can shake and swing at a certain angle relative to the lower base plate 102.

[0025] A swing drive assembly is also provided on the lower substrate 102 to provide power for the swing of the upper substrate 101. There are two ways to implement the swing drive assembly. The first way of the swing drive assembly is as follows: Figure 6 , Figure 9 and Figure 10 The swing drive assembly is a plurality of vertical drive telescopic rods 10 fixedly mounted on the outer edge of the upper surface of the lower base plate 102 in a circumferential array. By controlling the plurality of vertical drive telescopic rods 10 to extend and reset in the order of the circumferential arrangement, the upper base plate 101 is driven to swing around the ball-and-socket connection, thereby achieving a circumferential movement of the ankle joint. The second swing drive assembly method refers to Figures 3 - 5 , Figure 7 and Figure 8 The swing driving assembly is a plurality of electromagnets 9 fixedly mounted on the upper surface of the lower base plate 102 and arranged in a circular array along the outer edge of the lower base plate 102, a permanent magnet 8 fixed on the lower surface of the upper base plate 101 and corresponding to the plurality of electromagnets 9 on the lower base plate 102, and a plurality of position-limiting telescopic rods 105 near the center of the upper surface of the lower base plate 102. When the ankle pump does not need to be moved in a circular motion, the plurality of position-limiting telescopic rods 105 are in an extended state and contact the lower surface of the upper base plate 101, thereby ensuring the stability (horizontal state) of the upper base plate 101. ), when a circumferential motion is required, the plurality of limit telescopic rods 105 are in a shortened state, at which time the plurality of limit telescopic rods 105 do not conflict with the upper substrate 101, and the upper substrate 101 and the lower substrate 102 are only connected by a ball and socket, and by controlling a certain electromagnet 9 of the lower substrate 102 to be energized, the electromagnet 9 can be adsorbed to the corresponding permanent magnet 8 on the upper substrate 101, and the upper substrate 101 is tilted at this time, and by sequentially controlling the electromagnet 9 on the upper surface of the lower substrate 102 to be intermittently powered on and off, the upper substrate 101 can be shaken.

[0026] To achieve the control of the swinging angle and avoid damage caused by excessive force when the ankle joint makes a circular motion, in the first way of the above-mentioned swinging drive assembly, a third pressure sensor 11 is further provided at the top of the vertical drive telescopic rod 10. The third pressure sensor 11 is used to provide a pressure signal to the controller 12. When the pressure reaches the set value, the controller 12 controls the corresponding vertical drive telescopic rod 10 to shorten, and simultaneously controls the next vertical drive telescopic rod 10 to extend in sequence, so as to avoid excessive swinging angle and damage to the ankle joint. For the second way of the swinging drive assembly, the controller 12 controls the adsorption force between the electromagnet 9 and the permanent magnet 8 by controlling the magnitude of the current provided by the electromagnet 9 (generally, the greater the current, the greater the adsorption force of the electromagnet 9 on the permanent magnet 8. By presetting the magnitude of the provided current, the excessive adsorption force can be avoided), so as to avoid damage to the ankle joint during the ankle pump movement.

[0027] Furthermore, the present invention also provides two implementation ways of the above-mentioned linear drive assembly 3. Both ways of the linear drive assembly 3 can realize the sliding of the base 1 on the slide rail 2. First, there is a groove 201 on the slide rail 2, and a support body 106 is provided on the lower substrate 102 of the base 1, and the support body 106 is located inside the groove 201. As Figure 11 shown, the first way of the linear drive assembly 3 is that an electric telescopic rod 15 is provided on the slide rail 2, and the output end (driving end) of the electric telescopic rod 15 is fixed to the support body 106. The controller 12 controls the linear motion and the direction of the linear motion of the base 1 along the slide rail 2 by controlling the extension and shortening of the electric telescopic rod 15. As Figure 1 shown, the second way of the linear drive assembly 3 is that a motor 13 is provided at one end of the slide rail 2, and a lead screw 14 that is threadedly engaged with the support body 106 is provided at the output end of the motor 13. The sliding speed and direction of the base 1 on the slide rail 2 are controlled by controlling the rotation speed and direction of the motor 13.

[0028] Further, the linear drive assembly 3 is used to control the flexion and extension movements of the ankle pump exercise. In order to ensure that the ankle joint is not damaged during the flexion and extension movements of the ankle pump exercise, it is necessary to avoid a large horizontal thrust applied to the foot during the flexion and extension movements. To achieve the above purpose, a sliding block 502 is integrally provided at the bottom of the accommodating shell 5 of the binding member, a sliding cavity 107 is formed on the upper surface of the upper substrate 101, the sliding cavity 107 cooperates with the sliding block 502, a first pressure sensor 6 is installed at one end of the sliding cavity 107, and a second pressure sensor 7 is installed at the other end. The output ends of the first pressure sensor 6 and the second pressure sensor 7 are connected to the input end of the controller 12, and the output end of the controller 12 is used to issue a control signal, and the control signal is used to control the sliding direction of the linear drive assembly 3. Taking the example that the foot is driven forward by the base 1, first, the base 1 moves forward under the drive of the linear drive assembly 3. At this time, the foot is dragged by the leg and does not move forward synchronously with the base 1 directly, but remains stationary. At this time, relative sliding occurs between the base 1 and the accommodating shell 5 of the binding member, that is, the sliding block 502 at the bottom of the accommodating shell 5 slides in the sliding cavity 107. After the relative sliding causes the sliding block 502 to abut against the first pressure sensor 6, since the first pressure sensor 6 is fixedly connected to the upper substrate 101, the base 1 pushes the sliding block 502 at the bottom of the accommodating shell 5 forward through the first pressure sensor 6, that is, the binding member moves synchronously with the base 1. At this time, the force applied by the first pressure sensor 6 to the binding member is not less than the dragging force of the leg on the foot. When the foot moves to the most forward position, the value of the first pressure sensor 6 is in the maximum state. When the value of the first pressure sensor 6 reaches the set value, the controller 12 controls the linear drive assembly 3 to drive the base 1 to move in the reverse direction. In the initial stage of the reverse movement, the foot does not move synchronously with the base 1 under the dragging of the leg. When the force applied by the second pressure sensor 7 on the base 1 to the sliding block 502 is greater than the dragging force of the leg, the foot moves synchronously with the base 1. When the foot is retracted to the maximum extent, the value of the second pressure sensor 7 gradually increases. When it reaches the set value, the controller 12 controls the linear drive assembly 3 to drive the base 1 to move forward again. This cycle repeats. It should be further noted that the controller 12 mentioned above also has a display screen for realizing human-computer interaction. Specifically, this display screen is used to display a human-computer interaction interface, and the human-computer interaction interface includes a parameter setting interface for adjusting the operating parameters of the rehabilitation nursing device and a control operation interface for controlling the working state of the rehabilitation nursing device.
