Description

Technical Field

[0001] This invention relates to the field of detection device technology, and in particular to a handheld portable hemodialysis tubing venous chamber coagulation optical imaging detection device and a graded early warning method. Background Technology

[0002] During hemodialysis, coagulation is highly likely to occur in the venous chamber due to various factors, including differences in patient coagulation function, insufficient anticoagulant dosage, and changes in blood flow velocity. Because the blood is already concentrated after passing through the dialyzer and its flow rate slows down within the venous chamber, it becomes the most likely and first site for coagulation to occur in extracorporeal circulation. If venous chamber coagulation is not detected and treated promptly, it can lead to tubing blockage, impaired blood return, and complications such as hypotension and muscle spasms, exacerbating patient suffering and even threatening their lives. Therefore, accurate and real-time monitoring of venous chamber coagulation in hemodialysis tubing is of significant clinical importance for ensuring the safety and improving the effectiveness of hemodialysis treatment.

[0003] Currently, clinical methods for detecting coagulation in the venous chamber of hemodialysis tubing are as follows: First, indirectly inferring whether coagulation has occurred by relying on changes in venous pressure. This method has a significant lag, often only detecting pressure abnormalities when coagulation is already quite severe and tubing flow is obstructed, thus failing to provide early warning. Second, judging the coagulation status by directly observing changes in the color of the blood in the venous chamber, or using simple light sources to enhance the observation effect. However, this method relies entirely on the clinical experience of medical staff and is affected by subjective judgment differences, observation angles, ambient lighting, and other factors, making it difficult to guarantee accuracy and prone to misjudgment or missed judgment.

[0004] Based on the above reasons, this invention proposes a handheld portable hemodialysis tubing venous chamber coagulation optical imaging detection device and a graded early warning method to solve the problems existing in the prior art. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that the existing technology for judging coagulation in hemodialysis is inconvenient and prone to misjudgment or omission. Based on this, a handheld portable optical imaging detection device for coagulation in the venous chamber of hemodialysis tubing and a graded early warning method are provided, which has the advantages of high visualization and accurate early warning.

[0009] The data acquisition unit is used to acquire and preprocess the imaging data acquired by the optical imaging module.

[0010] The data analysis unit is used to analyze and process the preprocessed data to obtain a coagulation optical image at a specified height.

[0011] The image synthesis unit sorts and synthesizes the coagulation optical images acquired at various heights to obtain coagulation images within an acquisition cycle.

[0012] The image analysis and alarm unit performs coagulation blockage analysis based on coagulation images within one acquisition cycle and blockage analysis based on coagulation images within multiple adjacent acquisition cycles, and outputs the specified alarm conditions based on the analysis results.

[0013] The storage unit is used to store preset processing programs and coagulation image data;

[0014] The transmission unit is used for transmitting image data and interactive operations.

[0015] Preferably, the displacement component includes a motor, which is fixedly connected to the movable plate, and the output end of the motor is fixedly connected to a rotating shaft. A gear is fixedly connected to the rotating shaft, and a rack meshes with one side of the gear. The rack is fixedly connected to the inner wall of the vertical groove.

[0016] Preferably, the locking assembly includes side grooves, and several side grooves are provided on the left and right side walls of the mounting plate. A round shaft is movably connected in each side groove. A clamping plate is fixedly connected to the center of the round shaft, and a second spring is sleeved on the round shaft. The two ends of the second spring are fixedly connected to the clamping plate and the inner wall of the side groove, respectively. Several clamping plates on the same side are fixedly connected by a vertical plate.

[0017] Preferably, the side wall of the movable plate is provided with a plurality of spherical grooves, and the end of the crossbar near the fixed plate is fixedly connected with a ball head, the ball head being inserted into the spherical groove and movably connected to the spherical groove.

[0018] Preferably, a sliding groove is provided on the inner wall of the vertical groove, and a sliding plate is fixedly connected to the side wall of the movable plate. The sliding plates are respectively inserted into the sliding groove, and the sliding plates are movably connected to the sliding groove.

[0019] Preferably, the clamping plate is arc-shaped, and an anti-slip pad is fixedly connected to the side wall of the clamping plate.

[0020] Preferably, a connecting rope is fixedly connected to each of the two vertical plates, and the ends of the two connecting ropes away from the vertical plates are fixedly connected to the same horizontal plate, which passes through the handle and is movably connected to the handle.

[0021] Preferably, a through groove is provided on the side wall of the handle, and the two sides of the horizontal plate pass through the through groove respectively, and a limit plate is fixedly connected to the horizontal plate near the through groove.

[0022] A graded early warning method for a handheld portable hemodialysis tubing venous chamber coagulation optical imaging detection device includes the following steps:

[0023] S1: Medical staff hold the testing device by the handle and pull the horizontal plate. The horizontal plate drives the vertical plate to move through the connecting rope. The vertical plate drives the clamping plate to move. The clamping plate rotates around the circular axis and the second spring deforms. At this time, the mounting plate can be pressed tightly against the outer wall of the hemodialysis tubing venous chamber. By releasing the horizontal plate, the clamping plates on both sides clamp the hemodialysis tubing venous chamber under the elastic force of the second spring, thus completing the fixed installation operation between the testing device and the hemodialysis tubing venous chamber.

[0024] S2: The medical staff releases the handle and starts the control module. The control module starts the motor and the optical imaging module. The motor drives the gear to rotate through the shaft. The gear meshes with the rack and pinion, causing the movable plate to move from bottom to top in the vertical groove. At this time, under the elastic force of the first spring, the fixed plate can be pressed tightly against the outer wall of the venous chamber of the hemodialysis tubing. The optical imaging module continuously performs coagulation detection inside the venous chamber of the hemodialysis tubing and transmits the data detected at each position to the control module for analysis and processing.

[0025] S3: Driven by the motor, when the optical imaging module moves from one side of the venous chamber of the hemodialysis tubing to the other side, the motor stops running. At the same time, the image synthesis unit inside the control module synthesizes the coagulation optical images acquired at each position and outputs a complete coagulation image inside the venous chamber of the hemodialysis tubing. Meanwhile, the image analysis and alarm unit analyzes and processes the image and transmits the complete coagulation image data and alarm data to the external display device for display based on the transmission unit.

[0026] S4: If no coagulation image appears in the complete coagulation image, the output of the alarm condition is "hemodialysis normal";

[0027] S5: If the volume occupied by the complete coagulation image exceeds one-third of the internal volume of the venous chamber of the hemodialysis tubing, the alarm output will be "Stop immediately and replace the hemodialysis tubing". Medical staff need to perform the hemodialysis tubing replacement operation.

[0028] S6: If the volume occupied by the complete coagulation image is less than one-third of the internal volume of the venous chamber of the hemodialysis tubing and there is a specific coagulation image inside, the output of the alarm condition is "re-detect and closely observe". Medical staff start this detection device and repeat the above steps S1-S3 to obtain another complete coagulation image. The image analysis and alarm unit compares and processes the two complete coagulation images.

[0029] If the coagulation volume increases by less than 15% of the first volume and the total volume does not exceed one-third, the time for retesting will be automatically set based on the rate of increase. Once the test time is reached, the above steps S1-S3 will be repeated automatically until the coagulation volume exceeds one-third of the internal volume of the venous chamber in the hemodialysis tubing or hemodialysis is completed.

[0030] If the coagulation volume increases by more than 15% of the first volume but the total volume does not exceed one-third, repeat steps S1-S3 above. If the coagulation volume increases by more than 15% of the previous volume again, the medical staff will perform the procedure to replace the hemodialysis tubing.

[0031] If the coagulation volume detected again exceeds one-third of the internal volume of the venous chamber in the hemodialysis tubing, the medical staff will perform a hemodialysis tubing replacement procedure.

[0032] S7: If the complete coagulation image shows that the coagulation occurs at the inlet and outlet of the hemodialysis tubing venous reservoir, the alarm output will be "tubing maintenance". Medical staff need to manually handle the coagulation at the inlet and outlet of the hemodialysis tubing venous reservoir.

[0033] Compared with the prior art, the present invention has at least the following beneficial effects:

[0034] The present invention utilizes the elastic force of the first spring to make the fixing plate adhere tightly to the outer wall of the venous chamber of the hemodialysis tubing. Under the drive of the displacement component, the optical imaging module completes the coagulation detection inside the venous chamber of the hemodialysis tubing, thereby obtaining the volume of coagulation inside the venous chamber of the hemodialysis tubing, reducing the error of subjective human judgment, and effectively improving the accuracy of coagulation determination.

[0035] This invention uses the image synthesis unit of the control module to synthesize the coagulation optical images acquired at various locations, outputting a complete coagulation image inside the venous chamber of the hemodialysis tubing. Simultaneously, the image analysis and alarm unit analyzes and processes the image, constructing a graded early warning mechanism based on the size of the coagulation volume. This improves the accuracy and targeting of coagulation detection, provides medical staff with clear intervention opportunities and operational guidelines, ensures timely replacement of the hemodialysis tubing, and minimizes patient suffering and medical risks.

[0053] like Figure 1-8 As shown, an embodiment of the present invention provides a handheld portable hemodialysis tubing venous chamber coagulation optical imaging detection device, including a mounting plate 1, a vertical groove 2 at the center of the mounting plate 1, a movable plate 3 movably connected in the vertical groove 2, a fixed plate 4 provided on the front side of the movable plate 3, an optical imaging module 5 installed on the front side wall of the fixed plate 4, and a plurality of crossbars 6 movably connected on the rear side wall of the fixed plate 4, the crossbars 6 passing through the movable plate 3, and a first spring 7 sleeved on the crossbars 6, one end of the first spring 7 being fixedly connected to the movable plate 3, and the other end of the first spring 7 being fixedly connected to an annular plate 8, the annular plate 8 being fixedly connected to the crossbars 6;

[0054] In the technical solution of this embodiment, the optical imaging module 5 is implemented using a near-infrared spectroscopy detector. During use, the elastic force of the first spring 7 allows the crossbar 6 to drive the fixing plate 4 to stick tightly to the outer wall of the venous chamber of the hemodialysis tubing. At this time, the optical imaging module 5 emits near-infrared light. Based on the light intensity attenuation rate after emission, the coagulation detection inside the venous chamber of the hemodialysis tubing is completed, and the volume of coagulation inside the venous chamber of the hemodialysis tubing can be obtained, reducing the error of subjective human judgment and effectively improving the accuracy of coagulation determination.

[0055] The side wall of the movable plate 3 is provided with several spherical grooves 25. The crossbar 6 is fixedly connected to the end near the fixed plate 4 with a ball head 26. The ball head 26 is inserted into the spherical groove 25 and is movably connected to the spherical groove 25. Because the inner diameter of the spherical groove 25 is larger than the outer diameter of the ball head 26, the movable plate 3 can have a certain angle offset function, which can make the optical imaging module 5 closely fit the outer wall of the venous chamber of the hemodialysis tubing, ensuring the coagulation detection effect.

[0056] The movable plate 3 is provided with a displacement component 9, which includes a motor 14. The motor 14 is fixedly connected to the movable plate 3, and the output end of the motor 14 is fixedly connected to a rotating shaft 15. A gear 16 is fixedly connected to the rotating shaft 15, and a rack 17 meshes with one side of the gear 16. The rack 17 is fixedly connected to the inner wall of the vertical groove 2.

[0057] In the technical solution of this embodiment, the motor 14 drives the gear 16 to rotate through the rotating shaft 15, and the gear 16 meshes with the rack 17 to move, so that the movable plate 3 moves in the vertical groove 2, which enables the optical imaging module 5 to complete the automated detection operation of the venous chamber of the hemodialysis tubing, and the detection is highly efficient.

[0058] A sliding groove 27 is provided on the inner wall of the vertical groove 2, and a sliding plate 28 is fixedly connected to the side wall of the movable plate 3. The sliding plates 28 are respectively inserted into the sliding groove 27, and the sliding plates 28 are movably connected to the sliding groove 27, so that the movable plate 3 can move up and down stably in the vertical groove 2.

[0059] A handle 10, a control module 11, and a power module 12 are fixedly connected to the rear side wall of the mounting plate 1. The control module 11 includes a data acquisition unit, a data analysis unit, an image synthesis unit, a storage unit, and a transmission unit.

[0060] The data acquisition unit is used to acquire and preprocess the imaging data acquired by the optical imaging module 5.

[0061] The data analysis unit is used to analyze and process the preprocessed data to obtain a coagulation optical image at a specified height.

[0062] The image synthesis unit sorts and synthesizes the coagulation optical images acquired at various heights to obtain coagulation images within one acquisition cycle.

[0063] The image analysis and alarm unit performs coagulation blockage analysis based on coagulation images within one acquisition cycle and blockage analysis based on coagulation images within multiple adjacent acquisition cycles, and outputs the specified alarm conditions based on the analysis results.

[0064] The storage unit is used to store the preset processing program and coagulation image data;

[0065] The transmission unit is used for transmitting image data and for interactive operations;

[0066] In the technical solution of this embodiment, during the detection process, the optical imaging module 5 continuously performs coagulation detection inside the venous chamber of the hemodialysis tubing and transmits the data detected at each location to the data acquisition unit for processing. After completing one detection cycle, the image synthesis unit synthesizes the coagulation optical images acquired at each location and outputs a complete coagulation image inside the venous chamber of the hemodialysis tubing. At the same time, the image analysis and alarm unit analyzes and processes the image and constructs a graded early warning mechanism based on the size of the coagulation volume to improve the accuracy and targeting of coagulation detection, provide medical staff with clear intervention opportunities and operation guidelines, ensure timely replacement of the hemodialysis tubing, and minimize patient suffering and medical risks.

[0067] Furthermore, locking components 13 are provided on the left and right side walls of the mounting plate 1. The locking components 13 include side grooves 18. Several side grooves 18 are provided on the left and right side walls of the mounting plate 1. A round shaft 19 is movably connected in each side groove 18. A clamping plate 20 is fixedly connected to the center of the round shaft 19. A second spring 21 is sleeved on the round shaft 19. The two ends of the second spring 21 are fixedly connected to the clamping plate 20 and the inner wall of the side groove 18, respectively. Several clamping plates 20 on the same side are fixedly connected by vertical plates 22. Connecting ropes 23 are fixedly connected to both vertical plates 22. The ends of the two connecting ropes 23 away from the vertical plates 22 are fixedly connected to the same horizontal plate 24. The horizontal plate 24 passes through the handle 10 and is movably connected to the handle 10. A through groove is provided on the side wall of the handle 10. The horizontal plate 24 passes through the two through grooves on both sides, and a limit plate is fixedly connected to the horizontal plate 24 near the through groove.

[0068] In the technical solution of this embodiment, medical staff hold the detection device by the handle 10 and pull the horizontal plate 24. The horizontal plate 24 drives the vertical plate 22 to move through the connecting rope 23. The vertical plate 22 drives the clamping plate 20 to move. The clamping plate 20 rotates around the circular shaft 19 and the second spring 21 deforms. At this time, the mounting plate 1 can be tightly attached to the outer wall of the hemodialysis tubing venous chamber. By releasing the horizontal plate 24, under the elastic force of the second spring 21, the clamping plates 20 on both sides clamp the hemodialysis tubing venous chamber, completing the fixed installation operation between the detection device and the hemodialysis tubing venous chamber.

[0069] The clamping plate 20 is arc-shaped, and anti-slip pads 29 are fixedly connected to the side wall of the clamping plate 20 to improve the clamping force between the detection device and the venous chamber of the hemodialysis tubing, thereby improving the stability of the installation.

[0070] A graded early warning method for a handheld portable hemodialysis tubing venous chamber coagulation optical imaging detection device includes the following steps:

[0071] S1: Medical staff hold the testing device by the handle 10 and pull the horizontal plate 24. The horizontal plate 24 drives the vertical plate 22 to move through the connecting rope 23. The vertical plate 22 drives the clamping plate 20 to move. The clamping plate 20 rotates around the circular shaft 19 and the second spring 21 deforms. At this time, the mounting plate 1 can be pressed tightly against the outer wall of the hemodialysis tubing venous chamber. By releasing the horizontal plate 24, under the elastic force of the second spring 21, the clamping plates 20 on both sides clamp the hemodialysis tubing venous chamber, completing the fixed installation operation between the testing device and the hemodialysis tubing venous chamber.

[0072] S2: The medical staff releases the handle 10 and starts the control module 11. The control module 11 starts the motor 14 and the optical imaging module 5. The motor 14 drives the gear 16 to rotate through the shaft 15. The gear 16 meshes with the rack 17 to move, so that the movable plate 3 moves from bottom to top in the vertical groove 2. At this time, under the elastic force of the first spring 7, the fixed plate 4 can be pressed tightly against the outer wall of the venous chamber of the hemodialysis tubing. The optical imaging module 5 continuously performs coagulation detection inside the venous chamber of the hemodialysis tubing and transmits the data detected at each position to the control module 11 for analysis and processing.

[0073] S3: Driven by motor 14, when the optical imaging module 5 moves from one side of the hemodialysis tubing venous chamber to the other side, the operation of motor 14 stops. At the same time, the image synthesis unit inside the control module 11 synthesizes the collected coagulation optical images and outputs a complete coagulation image inside the hemodialysis tubing venous chamber. Meanwhile, the image analysis and alarm unit analyzes and processes the image and transmits the complete coagulation image data and alarm data to the external display device for display based on the transmission unit.

[0074] S4: If no coagulation image appears in the complete coagulation image, the output of the alarm condition is "hemodialysis normal";

[0075] S5: If the volume occupied by the complete coagulation image exceeds one-third of the internal volume of the venous chamber of the hemodialysis tubing, the alarm output will be "Stop immediately and replace the hemodialysis tubing". Medical staff need to perform the hemodialysis tubing replacement operation.

[0076] S6: If the volume occupied by the complete coagulation image is less than one-third of the internal volume of the venous chamber of the hemodialysis tubing and there is a specific coagulation image inside, the output of the alarm condition is "re-detect and closely observe". Medical staff start this detection device and repeat the above steps S1-S3 to obtain another complete coagulation image. The image analysis and alarm unit compares and processes the two complete coagulation images.

[0077] If the coagulation volume increases by less than 15% of the first volume and the total volume does not exceed one-third, the time for retesting will be automatically set based on the rate of increase. Once the test time is reached, the above steps S1-S3 will be repeated automatically until the coagulation volume exceeds one-third of the internal volume of the venous chamber in the hemodialysis tubing or hemodialysis is completed.

[0078] If the coagulation volume increases by more than 15% of the first volume but the total volume does not exceed one-third, repeat steps S1-S3 above. If the coagulation volume increases by more than 15% of the previous volume again, the medical staff will perform the procedure to replace the hemodialysis tubing.

[0079] If the coagulation volume detected again exceeds one-third of the internal volume of the venous chamber in the hemodialysis tubing, the medical staff will perform a hemodialysis tubing replacement procedure.

[0080] S7: If the complete coagulation image shows that the coagulation occurs at the inlet and outlet of the hemodialysis tubing venous reservoir, the alarm output will be "tubing maintenance". Medical staff need to manually handle the coagulation at the inlet and outlet of the hemodialysis tubing venous reservoir.

10. The graded early warning method for the handheld portable hemodialysis tubing venous chamber coagulation optical imaging detection device according to any one of claims 1-9, characterized in that, Includes the following steps: S1: Medical staff hold the testing device by the handle (10) and pull the horizontal plate (24). The horizontal plate (24) drives the vertical plate (22) to move through the connecting rope (23). The vertical plate (22) drives the clamping plate (20) to move. The clamping plate (20) rotates around the circular shaft (19) and the second spring (21) deforms. At this time, the mounting plate (1) can be pressed tightly against the outer wall of the hemodialysis tubing venous pot. By releasing the horizontal plate (24), under the elastic force of the second spring (21), the clamping plates (20) on both sides clamp the hemodialysis tubing venous pot, thus completing the fixed installation operation between the testing device and the hemodialysis tubing venous pot. S2: The medical staff releases the handle (10) and starts the control module (11). The control module (11) starts the motor (14) and the optical imaging module (5). The motor (14) drives the gear (16) to rotate through the shaft (15). The gear (16) meshes with the rack (17) to move, so that the movable plate (3) moves from bottom to top in the vertical groove (2). At this time, under the elastic force of the first spring (7), the fixed plate (4) can be pressed against the outer wall of the venous chamber of the hemodialysis tubing. The optical imaging module (5) continuously performs coagulation detection inside the venous chamber of the hemodialysis tubing and transmits the data detected at each position to the control module (11) for analysis and processing. S3: Driven by the motor (14), when the optical imaging module (5) moves from one side of the venous chamber of the hemodialysis tubing to the other side, the operation of the motor (14) is stopped. At the same time, the image synthesis unit inside the control module (11) synthesizes the coagulation optical images collected at each position and outputs a complete coagulation image inside the venous chamber of the hemodialysis tubing. Meanwhile, the image analysis and alarm unit analyzes and processes the image and transmits the complete coagulation image data and alarm data to the external display device for display based on the transmission unit. S4: If no coagulation image appears in the complete coagulation image, the output of the alarm condition is "hemodialysis normal"; S5: If the volume occupied by the complete coagulation image exceeds one-third of the internal volume of the venous chamber of the hemodialysis tubing, the alarm output will be "Stop immediately and replace the hemodialysis tubing". Medical staff need to perform the hemodialysis tubing replacement operation. S6: If the volume occupied by the complete coagulation image is less than one-third of the internal volume of the venous chamber of the hemodialysis tubing and there is a specific coagulation image inside, the alarm output at this time is "re-detect and closely observe". Medical staff start this detection device and repeat the above steps S1-S3 to obtain another complete coagulation image. The image analysis and alarm unit performs comparative processing based on the two complete coagulation images. If the coagulation volume increases by less than 15% of the first volume and the total volume does not exceed one-third, the time for retesting will be automatically set based on the rate of increase. Once the test time is reached, the above steps S1-S3 will be repeated automatically until the coagulation volume exceeds one-third of the internal volume of the venous chamber in the hemodialysis tubing or hemodialysis is completed. If the coagulation volume increases by more than 15% of the first volume but the total volume does not exceed one-third, repeat steps S1-S3 above. If the coagulation volume increases by more than 15% of the previous volume again, the medical staff will perform the procedure to replace the hemodialysis tubing. If the coagulation volume detected again exceeds one-third of the internal volume of the venous chamber in the hemodialysis tubing, the medical staff will perform a hemodialysis tubing replacement procedure. S7: If the complete coagulation image shows that the coagulation occurs at the inlet and outlet of the hemodialysis tubing venous reservoir, the alarm output will be "tubing maintenance". Medical staff need to manually handle the coagulation at the inlet and outlet of the hemodialysis tubing venous reservoir.
