Description

Technical Field

[0001] This invention relates to the field of medical auxiliary equipment, specifically to an ultrasound imaging-assisted screening system for chronic kidney disease. Background Technology

[0002] Chronic kidney disease is a difficult disease to cure and has become a global public health problem. It has a high morbidity and mortality rate, and there are no specific drugs or treatments. The main goal of treatment is to control complications and slow the progression of the disease to avoid entering the uremia stage. Therefore, it is necessary to detect and treat it as early as possible.

[0003] Chronic kidney disease (CHD) often progresses slowly and over a long period, and many CHD symptoms may not be prominent. Early detection, effective assessment of the patient's condition throughout the long course of the disease, and timely adjustment of treatment plans based on disease progression are crucial aspects of CHD prevention and treatment. Because CHD patients have few specific symptoms, this work relies heavily on accurate laboratory and imaging examinations. In some cases, a renal biopsy is necessary. This biopsy requires ultrasound guidance, with ultrasound localization and puncture performed by separate physicians. The ultrasound equipment is located at a distance, making observation and operation difficult. Furthermore, the physician preparing the instruments needs to hold the patient at the puncture site during the procedure, and sometimes additional medical staff are required to assist. Summary of the Invention

[0004] To address the above issues, this invention provides an ultrasound imaging-assisted screening system for chronic kidney disease. The system has a simple module structure and can fix the smart display on the bed, allowing doctors to operate and observe at the bedside at any time. During the puncture process, it can assist medical staff in pressing the puncture site, making the operation more convenient for medical staff.

[0005] To address the above technical problems, this invention provides an ultrasound imaging-assisted screening system for chronic kidney disease, comprising an ultrasound module. The ultrasound module includes a smart display and an ultrasound probe electrically connected to the smart display. The ultrasound probe can generate multiple corresponding ultrasound emission signals according to different tilt angles and receive multiple corresponding ultrasound reflection signals. The smart display includes a display screen and a signal processing unit. The signal processing unit controls the ultrasound probe to generate one of the ultrasound emission signals and receives the ultrasound reflection signal corresponding to that ultrasound emission signal, thereby generating a corresponding two-dimensional ultrasound image based on the ultrasound reflection signal. The signal processing unit then generates a three-dimensional ultrasound image based on the two-dimensional ultrasound image and the corresponding tilt angle.

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0021] Example:

[0022] See attached Figure 1 To be continued Figure 5 An ultrasound imaging-assisted screening system for chronic kidney disease includes an ultrasound module. The ultrasound module includes a smart display 2 and an ultrasound probe 1 electrically connected to the smart display 2. The ultrasound probe 1 can generate multiple corresponding ultrasound emission signals according to different tilt angles and receive multiple corresponding ultrasound reflection signals. The smart display 2 includes a display screen and a signal processing unit. The signal processing unit controls the ultrasound probe 1 to generate one of the ultrasound emission signals and receives the ultrasound reflection signal corresponding to that ultrasound emission signal, so as to generate a corresponding two-dimensional ultrasound image based on the ultrasound reflection signal. The signal processing unit then generates a three-dimensional ultrasound image based on the two-dimensional ultrasound image and the corresponding tilt angle.

[0023] The signal processing unit obtains the corrected coordinate point based on the ultrasonic transmission signal and the ultrasonic reflection signal. Then, it obtains the first time when the ultrasonic transceiver reaches the corrected coordinate point and the second time when it reaches the reference point. The pixel image of the corrected coordinate point is adjusted in a timely manner according to the first and second times, and the pixel image is adjusted to the same arc as the reference point. The arc is centered on the ultrasonic transceiver, and the distance from the pixel image to the reference point to the center is the same. After the above processing, the image quality of the ultrasonic image can be improved.

[0024] This embodiment also includes a support module one, a support module two, and a pressing module. Support module one includes a square base 3. Support rods 4 are provided at both ends of the top of the square base 3. The support rods 4 are horizontally arranged and parallel to each other. The support rods 4 can move along the length of the top of the square base 3. In this embodiment, both ends of the top surface of the square base 3 have notches 34 passing through the thickness direction of the square base 3. Notches 34 are arranged along the length direction of the support rods 4. The bottom of notches 34 has a bottom groove 35 passing through the thickness direction of the square base 3. The width of the bottom groove 35 is longer than the width of notches 34. The bottom of the support rods 4 has a slider 36 located within notches 34. The bottom of slider 36 has a slider 37 located within the bottom groove 35. Both sliders 36 and 37 are arranged along the length direction of the support rods 4. Slider 36 and 37 are integrally manufactured, and slider 36 is welded to the bottom of the support rods 4. The side wall of slider 36 fits against the inner wall of notch 34, and the side wall of slider 37 fits against the inner wall of the bottom groove 35. Slider 36 can slide along notch 34, and slider 37 can slide along the bottom groove 35. Therefore, the support rod 4 can move along the thickness direction of the square base 3 without falling off the square base 3.

[0025] One end of the support rod 4 has multiple through holes 5 equidistantly arranged along the length of the support rod 4, and the through holes 5 pass through the thickness direction of the support rod 4. At the ends of the two support rods 4 away from the through holes 5, respectively, there are pad blocks 6 and operating blocks 7. The pad blocks 6 and operating blocks 7 are welded to the corresponding support rods 4.

The connecting rod 19 is bonded to the vertical pressure rod 15. A vertically arranged rotating column 20 is fitted around the outer periphery of the connecting rod 19. The rotating column 20 can rotate around the connecting rod 19, and a certain amount of force is required to rotate the rotating column 20. A pressure plate 21 is provided at the bottom of the rotating column 20. In order to prevent the edge of the pressure plate 21 from pressing down on the patient, this embodiment has a sponge pad 43 that is bonded to the pressure plate 21 and can be torn off at the bottom of the pressure plate 21.

[0029] The side wall of the annular groove 10 is provided with a semi-annular perforation 40 arranged along the annular direction of the annular groove 10. The perforation 40 is located away from the side where the first perforation 5 is located. The side of the slider 11 facing the perforation 40 is provided with a connecting block 41 that passes through the perforation 40. The end of the connecting block 41 away from the slider 11 is provided with a push plate 42. The connecting block 41, the push plate 42 and the slider 11 are all bonded together. When the horizontal rod 14 is rotated, in order to prevent the slider from getting stuck, the push plate 42 can be moved at the same time to push the slider.

[0030] Support module two includes a horizontal plate and two insert rods 22 located at the bottom of the horizontal plate. The insert rods 22 are welded to the horizontal plate, and the two insert rods 22 can pass through the through holes of the two support rods 4 respectively. At this time, the horizontal plate is located between the tops of the two support rods 4. The top of the horizontal plate is provided with a connecting post 23 whose bottom end is inserted into the horizontal plate and can rotate relative to the horizontal plate. The bottom of the connecting post 23 is provided with a limiting plate 24 located in the horizontal plate and can rotate relative to the horizontal plate. The limiting plate 24 and the connecting post 23 are integrally manufactured. The cross-sectional area of ​​the limiting plate 24 is larger than the cross-sectional area of ​​the connecting post 23, and the central axis of the limiting plate 24 coincides with the central axis of the connecting post 23. The top of the connecting column 23 is provided with a horizontal cylinder 25 located inside the connecting column 23 and horizontally arranged. The smart display 2 is located on the top of the horizontal cylinder 25. Both ends of the horizontal cylinder 25 are provided with limiting rods 26 located inside the connecting column 23 and rotatable relative to the connecting column 23. The limiting rods 26 and the horizontal cylinder 25 are made as one piece. A certain amount of force is required to make the horizontal cylinder 25 rotate inside the connecting column 23.

[0031] The bottom end of the insertion rod 22 is provided with a fixing rod 27, and the top of the fixing rod 27 is provided with a slot 28 for the insertion rod 22 to be inserted. The top and bottom ends of the side of the fixing rod 27 away from the other insertion rod 22 are provided with horizontally arranged clamping plates 29. The side of the fixing rod 27 facing the clamping plate 29 is provided with a sliding groove 30 arranged along the length direction of the insertion rod 22. The end of the clamping plate 29 facing the sliding groove 30 is provided with a slider 31 located in the sliding groove 30. The slider 31 can slide in the sliding groove 30. The bottom of the fixing rod 27 is provided with a bidirectional screw 32 that passes through the fixing rod 27 and the slide groove 30. The bidirectional screw 32 is arranged along the length of the slide groove 30. The bidirectional screw 32 passes through two sliders 31 in sequence. The sliders 31 are threadedly connected to the bidirectional screw 32. The top of the bidirectional screw 32 is provided with a limiting block 33 located at the top of the fixing rod 27. The limiting block 33 is welded to the bidirectional screw 32. When the bidirectional screw 32 rotates, the two clamping plates 29 move closer or further away from each other, thereby clamping the clamping plates 29 on the edge of the hospital bed. This is suitable for bed edges of different thicknesses.

[0032] The operating principle of this embodiment is as follows: During use, the square base 3 is placed on the bed. The support rod 4 is moved according to the patient's body shape (back width) so that the pressure plate 21 can rotate to the puncture point. Then, the insertion rod 22 is inserted into the puncture hole until the horizontal plate is at the top of the two support rods 4. Subsequently, the clamps 29 are adjusted so that the two sets of clamps 29 clamp the edge of the bed, thus fixing the support rods 4 and the horizontal rod 14. During use, the system is controlled via the touchscreen of the intelligent display screen, and images are displayed on the intelligent display screen. When the pressure plate 21 is not in use, the end of the horizontal rod 14 near the pad 6 is pressed against the pad 6, and both springs 17 are in a stretched state. During the puncture, if necessary... Press down on the puncture point, first lift the end of the horizontal bar 14 near the pad 6, and rotate the horizontal bar 14 away from the support bar 4 to rotate the pressure plate 21 to the puncture area, so that the pressure plate 21 presses on the gauze at the puncture point. Release the horizontal bar 14, the spring 17 retracts, and pull the horizontal bar 14 down. The horizontal bar 14 is in an inclined state (the maximum inclination angle of the horizontal bar 14 is when the horizontal bar 14 is blocked by the annular inclined surface 9), thereby pressing the pressure plate 21 tightly on the puncture point. Since the pressure plate 21 can rotate relative to the vertical pressure bar 15, it can adapt to the curved surface of the back and side of the human body. When it is not necessary to press down on the puncture point, lift the horizontal bar 14 and rotate the horizontal bar 14 onto the support bar 4.
