[0002] The lower limb lymphedema detection device consists of a measuring probe (including a high-precision bioimpedance sensor array with special electrode material and adjustable probe), a data acquisition module (sensor signal amplification, filtering, analog-to-digital conversion), a data processing unit (using a high-performance processor to analyze and calculate relevant parameters and store data), a display and interaction module (the display screen intuitively presents the results and has operation buttons or a touch screen), and a communication module (supports Bluetooth, Wi-Fi, USB and other connection methods). Based on the principle of bioimpedance, the probe contacts the skin to transmit alternating current signals, and the lymphedema situation is judged and quantitatively analyzed based on the impedance difference under different tissue states. It has the advantages of being non-invasive, fast and convenient, quantifiable, and easy to manage data and provide remote medical support.

[0015] The present invention has the following beneficial effects:

[0016] (1) For a lower limb lymphedema detection device of the present invention, when the thigh is inside the annular block, both the first limiting spring and the second limiting spring will undergo compressive deformation, ensuring that the probe plate always closely adheres to the patient's leg during the inspection. Then, the driving motor is started. The driving motor drives the threaded rod to rotate. The threaded rod drives the internally threaded block to move towards the L-shaped block. The internally threaded block drives the L-shaped slider to move. The L-shaped slider drives the annular block to move synchronously. The annular block will rotate under the thread action of the L-shaped threaded plate. At this time, a plurality of probe plates will rotate synchronously under the action of the annular block, enabling the probe plates to rotate synchronously when moving, improving the inspection coverage rate and ensuring the accuracy of the inspection results. During the rotation of the annular block, the limiting round rod will also rotate synchronously with the limiting rod. At this time, the rotating ring will also rotate on the connecting block, ensuring the consistency of the rotation of the limiting round rod and the annular block. When the annular block moves to the position of the patient's calf, the工字 block will move towards the leg under the action of the limiting round rod. At this time, the probe plate will continue to closely adhere to the patient's calf under the limiting action of the limiting round rod, improving the adaptability and flexibility of the device;

[0017] (2) For the detection device for lower limb lymphedema of the present invention, when in use, the patient stretches the foot into the rotating ring and the annular block, then places the ankle on the arc opening of the L-shaped block, and then rotates the threaded lifting rod. Under the limiting action of the limiting slide rod, the threaded lifting rod will drive the L-shaped block to rise. The L-shaped block will drive the strip-shaped block to move towards the L-shaped block, enabling patients with different leg lengths to use it, improving the flexibility of the device. When the foot is placed into the arc opening of the L-shaped block, the foot will contact the two clamping plates. The two clamping plates will move away from each other, and the strip-shaped clamping blocks driven by the clamping plates will move away from each other. At this time, the clamping spring will undergo tensile deformation, and under the action of the spring, the clamping plates will hold against the patient's foot, making a preliminary fixation of the foot driven by the patient, thereby facilitating the patient to adjust a comfortable posture and making the device more user-friendly;

[0018] (3) For the detection device for lower limb lymphedema of the present invention, after the patient adjusts to a comfortable posture, the air pump is started. The air pump will input gas into the U-shaped air box through the air delivery pipe. At this time, the U-shaped plate in the U-shaped air box will rise, the U-shaped plate will drive the L-shaped movable plate to rise, the L-shaped movable plate will drive the T-shaped block to rise, and the T-shaped block will enter the triangular groove and come into contact with the triangular groove. As the L-shaped movable plate continues to rise, at this time, the fixed spring will undergo tensile deformation to make the T-shaped block fit more tightly against the triangular groove. The T-shaped block pressing against the triangular groove will cause a force for the strip-shaped clamping blocks to approach each other, thereby improving the stability of the strip-shaped clamping blocks and preventing the patient from shaking the body due to discomfort or itching during the examination, resulting in inaccurate examination results;

[0019] (4) For the detection device for lower limb lymphedema of the present invention, during the continuous air injection process of the air pump, the air pressure in the U-shaped air box will gradually increase. Since the elastic force of the sealing spring is greater than the elastic force of the fixed spring, when the fixed spring is stretched to the maximum (after the patient's foot has been fixed and clamped sufficiently), at this time, the gas will enter the T-shaped sliding box through the through hole, and the T-shaped sliding box will be pushed out of the sealing cover under the action of the gas. When the exhaust hole on the T-shaped sliding box leaves the sealing cover, the gas will be discharged from the exhaust hole, thereby maintaining the air pressure for the clamping plates to clamp the patient's foot and preventing the patient's foot from experiencing pain due to excessive air pressure and excessive clamping force, making the device more user-friendly.

[0020] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] like Figure 3 As shown, an L-shaped threaded plate 508 is fixedly installed on the top of the bar block 3, the annular block 501 is threadedly connected to the L-shaped threaded plate 508, two connecting blocks 509 are fixedly installed on the front and back of the L-shaped threaded plate 508, two rotating rings 510 are rotatably installed on the plurality of connecting blocks 509, and two limiting round rods 511 are fixedly installed on the side of the two rotating rings 510 away from each other.

[0036] During the rotation of the annular block 501, the limiting rod 511 will also rotate synchronously with the limiting rod 506. At this time, the swivel 510 will also rotate on the connecting block 509 to ensure the consistency of the rotation of the limiting rod 511 and the annular block 501. When the annular block 501 moves to the patient's calf position, the I-block 503 will move toward the leg under the action of the limiting rod 511. At this time, the probe plate 505 will continue to be close to the patient's calf under the limiting action of the limiting rod 511, thereby improving the adaptability and flexibility of the device.

[0037] As Figure 3 and Figure 6 shown, a movable mechanism 6 is provided on the strip block 3. The movable mechanism 6 includes a sliding groove 601 opened on the strip block 3. A threaded rod 602 is rotatably installed in the sliding groove 601. A driving motor 603 is fixedly installed on the front surface of the strip block 3. The front end of the threaded rod 602 extends outside the strip block 3 and is fixedly connected to the output shaft of the driving motor 603. An internally threaded block 604 is slidably installed in the sliding groove 601. The threaded rod 602 penetrates through the internally threaded block 604 and is threadedly connected to the internally threaded block 604.

[0038] Start the driving motor 603. The driving motor 603 drives the threaded rod 602 to rotate, and the threaded rod 602 drives the internally threaded block 604 to move in the direction close to the L-shaped block 2.

[0039] As Figure 1 and Figure 6 shown, annular chutes 605 are respectively opened on the front and back surfaces of the annular block 501. L-shaped sliders 606 are respectively fixedly installed on the front and back surfaces of the internally threaded block 604. The two L-shaped sliders 606 respectively extend into the two annular chutes 605 and are respectively slidably connected to the two annular chutes 605. A threaded lifting rod 607 is rotatably installed on the top of the L-shaped plate 1. The top end of the threaded lifting rod 607 extends into the L-shaped block 2 and is threadedly connected to the L-shaped block 2. A limiting slide rod 608 is fixedly installed on the top of the L-shaped plate 1. The top end of the limiting slide rod 608 extends into the L-shaped block 2 and is slidably connected to the L-shaped block 2.

[0040] The internally threaded block 604 drives the L-shaped slider 606 to move. The L-shaped slider 606 drives the annular block 501 to move synchronously. The annular block 501 will rotate under the thread action of the L-shaped threaded plate 508. At this time, several probe plates 505 will rotate synchronously under the action of the annular block 501, so that the probe plates 505 rotate synchronously when moving, improving the inspection coverage rate.

[0041] As Figure 2 shown, a fixing mechanism 7 is provided on the back surface of the L-shaped plate 1. The fixing mechanism 7 includes an air pump 701 fixedly installed on the back surface of the L-shaped plate 1. A U-shaped air tank 702 is fixedly installed on the back surface of the L-shaped block 2. An air delivery pipe 703 is fixedly installed on the top of the air pump 701. The top end of the air delivery pipe 703 is fixedly connected to the bottom end of the U-shaped air tank 702. A U-shaped plate 704 is slidably installed in the U-shaped air tank 702.

[0042] After the patient adjusts to a comfortable position, start the air pump 701. The air pump 701 will input gas into the U-shaped air tank 702 through the air delivery pipe 703. At this time, the U-shaped plate 704 in the U-shaped air tank 702 will rise.

[0043] As Figure 2 and Figure 7As shown in the figure, two L-shaped movable plates 705 are fixedly installed at the top of the C-shaped plate 704. The tops of the two L-shaped movable plates 705 respectively extend outside the C-shaped air box 702 and are both slidably connected to the C-shaped air box 702. T-shaped blocks 706 are slidably installed on the two L-shaped movable plates 705 respectively. The two T-shaped blocks 706 respectively penetrate through the two L-shaped movable plates 705. Fixed springs 707 are respectively sleeved on the two T-shaped blocks 706. The bottom ends of the two fixed springs 707 are respectively fixedly connected to the two T-shaped blocks 706, and the top ends of the two fixed springs 707 are respectively fixedly connected to the two L-shaped movable plates 705.

[0044] The C-shaped plate 704 drives the L-shaped movable plate 705 to rise. The L-shaped movable plate 705 drives the T-shaped block 706 to rise. The T-shaped block 706 will enter the triangular groove 805 and come into contact with the triangular groove 805.

[0045] As Figure 1 and Figure 7 As shown in the figure, two clamping mechanisms 8 are arranged on the L-shaped block 2. The clamping mechanism 8 includes two strip-shaped clamping blocks 801 slidably installed on the L-shaped block 2. A clamping plate 802 is fixedly installed at the right end of the strip-shaped clamping block 801. A rectangular mounting plate 803 is fixedly installed at the left end of the strip-shaped clamping block 801. A clamping spring 804 is fixedly installed on the right side of the rectangular mounting plate 803. The right end of the clamping spring 804 is fixedly connected to the L-shaped block 2. A triangular groove 805 is opened at the bottom of the strip-shaped clamping block 801.

[0046] As the L-shaped movable plate 705 continues to rise, at this time, the fixed spring 707 will undergo tensile deformation to make the T-shaped block 706 fit more tightly against the triangular groove 805. The T-shaped block 706 pressing against the triangular groove 805 will cause a force that makes the strip-shaped clamping blocks 801 approach each other, thereby improving the stability of the strip-shaped clamping blocks 801 and preventing the patient from shaking their body due to discomfort or itching during the examination, resulting in inaccurate examination results.

[0047] As Figure 8 As shown in the figure, a sealing cover 806 is fixedly installed on the back of the C-shaped air box 702. A number of through holes 807 are opened on the back of the C-shaped air box 702. A T-shaped sliding box 808 is slidably installed in the sealing cover 806. A number of exhaust holes 809 are respectively opened on the left and right inner walls of the T-shaped sliding box 808. A sealing spring 810 is fixedly installed on the back inner wall of the T-shaped sliding box 808. The front end of the sealing spring 810 is fixedly connected to the C-shaped air box 702.

[0048] When the fixing spring 707 is stretched to the maximum and is sufficient to fix and clamp the patient's foot, the gas will enter the T-shaped slide box 808 through the through hole 807, and the T-shaped slide box 808 will be pushed out of the sealing cover 806 under the action of the gas. When the exhaust hole 809 on the T-shaped slide box 808 leaves the sealing cover 806, the gas will be discharged from the exhaust hole 809, thereby maintaining the air pressure of the clamping plate 802 to clamp the patient's foot, and avoiding excessive air pressure and excessive clamping force that may cause pain in the patient's foot, making the device more humane.

[0049] When the thigh is in the annular block 501, the limit spring 1 504 and the limit spring 2 507 will be compressed and deformed to ensure that the probe plate 505 is always in close contact with the patient's leg during the examination. Then the drive motor 603 is started, the drive motor 603 drives the threaded rod 602 to rotate, the threaded rod 602 drives the internal thread block 604 to move in the direction close to the L-shaped block 2, the internal thread block 604 drives the L-shaped slider 606 to move, the L-shaped slider 606 drives the annular block 501 to move synchronously, and the annular block 501 is moved in the L-shaped threaded plate 508. The probe plates 505 will rotate under the action of the thread. At this time, the probe plates 505 will rotate synchronously under the action of the annular block 501, so that the probe plates 505 rotate synchronously when moving, thereby improving the coverage of the inspection and ensuring the accuracy of the inspection results. During the rotation of the annular block 501, the limiting rod 511 will also rotate synchronously with the limiting rod 506. At this time, the swivel 510 will also rotate on the connecting block 509 to ensure the consistency of the rotation of the limiting rod 511 and the annular block 501. When the annular block 501 moves to the patient's calf position , the I-shaped block 503 will move towards the leg under the action of the limiting rod 511, and the probe plate 505 will continue to be close to the patient's calf under the limiting action of the limiting rod 511, thereby improving the adaptability and flexibility of the device; when in use, the patient extends his foot into the swivel 510 and the annular block 501, and then the patient's ankle is placed on the arc of the L-shaped block 2, and then the threaded lifting rod 607 is rotated, and the threaded lifting rod 607 will drive the L-shaped block 2 to rise under the limiting action of the limiting slide bar 608, and the L-shaped block 2 will drive the strip block 3 Move toward the direction close to the L-shaped block 2 so that patients with different leg lengths can use it, improving the flexibility of the device. When the foot is placed in the arc of the L-shaped block 2, the foot will contact the two clamping plates 802, and the two clamping plates 802 will move away from each other, and the clamping plates 802 will drive the bar clamping blocks 801 to move away from each other. At this time, the clamping spring 804 will be stretched and deformed. Under the action of the spring, the clamping plate 802 will support the patient's foot, and the patient's driven foot will be initially fixed, so that the patient can adjust to a comfortable posture, making the device more humane.

[0050] After the patient adjusts to a comfortable position, start the air pump 701. The air pump 701 will input gas into the U-shaped air box 702 through the air delivery pipe 703. At this time, the U-shaped plate 704 in the U-shaped air box 702 will rise. The U-shaped plate 704 drives the L-shaped movable plate 705 to rise. The L-shaped movable plate 705 drives the T-shaped block 706 to rise. The T-shaped block 706 will enter the triangular groove 805 and come into contact with the triangular groove 805. As the L-shaped movable plate 705 continues to rise, the fixed spring 707 will undergo tensile deformation to make the T-shaped block 706 fit more tightly against the triangular groove 805. The T-shaped block 706 pressing against the triangular groove 805 will cause the strip-shaped clamping blocks 801 to generate a force to approach each other, thereby improving the stability of the strip-shaped clamping blocks 801 and preventing the patient from shaking the body due to discomfort or itching during the examination, resulting in inaccurate examination results. During the continuous air supply of the air pump 701, the air pressure in the U-shaped air box 702 will gradually increase. Since the elastic force of the sealing spring 810 is greater than the elastic force of the fixed spring 707, when the fixed spring 707 is stretched to the maximum and is sufficient to fix and clamp the patient's foot, at this time, the gas will enter the T-shaped sliding box 808 through the through hole 807. The T-shaped sliding box 808 will be pushed out of the sealing cover 806 under the action of the gas. When the exhaust hole 809 on the T-shaped sliding box 808 leaves the sealing cover 806, the gas will be discharged from the exhaust hole 809, thereby maintaining the air pressure for the clamping plate 802 to clamp the patient's foot and preventing the patient's foot from experiencing pain due to excessive air pressure and excessive clamping force, making the device more user-friendly.
