Description

Technical Field

[0001] The invention relates to the technical field of peritoneal dialysis machine drainage peritoneal dialysis fluid detection, and in particular to a peritoneal dialysis machine drainage peritoneal dialysis fluid turbidity detection device. Background Art

[0002] As an important dialysis method, peritoneal dialysis is widely used to treat diseases such as renal failure. Peritoneal dialysis uses the body's own peritoneum as a dialysis membrane, and exchanges solutes and water with the plasma components in the capillaries on the other side of the peritoneum through the dialysate infused into the peritoneal cavity, thereby removing the metabolic products and excess water retained in the body, and at the same time replenishing the body's necessary substances through the dialysate.

[0003] Peritoneal dialysis-related peritonitis is the most common complication of peritoneal dialysis. At present, one of the evaluation methods for the clinical manifestations of peritoneal dialysis-related peritonitis is to observe whether the dialysis fluid is turbid. Normal dialysis fluid is clear, while the dialysis fluid may be milky white, rice soup-like or purulent during peritonitis. The conventional detection method is that peritoneal dialysis patients observe the peritoneal dialysis fluid with the human eye to roughly estimate the turbidity, but this method has obvious defects and inaccurate identification. Especially for patients with diabetic nephropathy, they often have comorbid retinopathy, and people with poor vision such as the elderly have poor recognition of the turbidity of the peritoneal dialysis fluid, which can easily lead to missed diagnosis or misdiagnosis of peritonitis, affecting the treatment effect and quality of life of patients. Therefore, there is an urgent need for a more accurate and convenient method for detecting the turbidity of peritoneal dialysis fluid to improve the diagnostic accuracy of peritoneal dialysis-related peritonitis.

In addition, it should be understood by those of ordinary skill in the art that the figures provided herein are for illustrative purposes and that the figures are not necessarily drawn to scale.

[0031] Please refer to Figures 1 to 3 In one embodiment of the present invention, a peritoneal dialysis machine drainage peritoneal dialysis fluid turbidity detection device is shown, which includes a detection box 100, a clamping mechanism, an optical signal transmitting module, a projection device 600, an optical signal receiving module and an analysis module.

[0032] like Figure 1 and Figure 2 As shown, the detection box 100 is a hollow cubic structure, the top surface of the detection box 100 is provided with an opening 101, and one side of the detection box 100 is provided with a lifting mechanism 200. Specifically, the lifting mechanism 200 is arranged at the rear side of the detection box 100, and the lifting mechanism 200 can be lifted and lowered. A hanging mechanism is provided that extends into / out of the detection box 100 from the opening 101, and the hanging mechanism is used to hang bagged peritoneal dialysis fluid.

[0033] like Figure 2 and Figure 3 As shown, a clamping mechanism is provided in the detection box 100, and the clamping mechanism is used to clamp the bagged peritoneal dialysis fluid located in the detection box 100 and suspended on the suspension mechanism. Specifically, under normal conditions, the clamping mechanism is in an unfolded state. When the bagged peritoneal dialysis fluid is tested, the clamping mechanism clamps the bagged peritoneal dialysis fluid so that the bagged peritoneal dialysis fluid is in a regular shape.

[0034] The optical signal transmitting module and the projection device 600 are both arranged in the detection box 100 and located on opposite sides of the clamping mechanism. The optical signal transmitting module is used to transmit an initial optical signal to the bagged peritoneal dialysis fluid clamped by the clamping mechanism. The initial optical signal is converted into an intermediate optical signal after penetrating the bagged peritoneal dialysis fluid and displayed on the projection device 600. The optical signal receiving module is used to capture the intermediate optical signal on the projection device 600 and generate an electrical signal. The signal input end of the analysis module is electrically connected to the signal output end of the optical signal receiving module, and the detection result of the bagged peritoneal dialysis fluid is obtained according to the signal analysis of the optical signal receiving module.

[0035] A peritoneal dialysis machine drainage peritoneal dialysis fluid turbidity detection device of the present invention, when detecting the bagged peritoneal dialysis fluid, the lifting mechanism 200 drives the suspension mechanism to rise to a preset height, and then hangs the bagged peritoneal dialysis fluid on the suspension mechanism; then, the lifting mechanism 200 drives the suspension mechanism to descend back to the detection box 100, and the clamping mechanism starts to operate to clamp the bagged peritoneal dialysis fluid into a shape close to a cube. After that, the initial light signal emitted from the optical signal emission module is converted into an intermediate light signal after penetrating the bagged peritoneal dialysis fluid. The projection of the intermediate light signal on the projection device 600 includes multiple bright areas and multiple shadow areas. The optical signal receiving module captures the bright area and the shadow area on the projection device 600, and converts them into image signals for later analysis and judgment. The analysis module uses its built-in central processing unit (CPU) and general purpose image processing unit (GPU) to analyze the image, thereby obtaining an accurate detection structure.

[0036] In an optional embodiment of the present invention, the hanging mechanism includes a connecting seat 301, a support rod 302 and a bearing plate 303. The connecting seat 301 is fixedly mounted on the side wall of the lifting slide of the lifting mechanism 200. There are at least two support rods 302, and the top ends of the support rods 302 are fixedly connected to the bottom surface of the bearing plate 303. The bottom ends of the support rods 302 are fixedly connected to the top surface of the connecting seat 301. A hook 304 is provided on the bottom surface of the bearing plate 303, and the hook 304 is used to hang bagged peritoneal dialysis fluid.

[0037] Specifically, the lifting mechanism 200 is a mature electric screw lifting mechanism in the prior art. The connecting seat 301 is fixed to the side wall of the lifting slide of the lifting mechanism 200 by multiple screws. Preferably, there are two support rods 302. The support rods 302 are provided so that the carrying plate 303 can be lifted and lowered between the top of the detection box 100 and the opening 101. The carrying plate 303 is lifted and lowered to cover or open the opening 101. More specifically, the specifications of the opening 101 are matched with the specifications of the carrying plate 303, so that the carrying plate 303 can close the opening 101 to prevent dust from entering the detection box 100. The carrying plate 303 is lifted and lowered by the lifting device without manual operation, and its operation is convenient.

[0038] like Figure 3 As shown, the clamping mechanism includes a driving motor 401, a double helical screw rod 402, a bearing seat 403, a mounting base plate 404 and a shaping clamp. The mounting base plate 404 is fixedly arranged above the bottom plate of the detection box 100 in parallel. Specifically, the four corners of the mounting base plate 404 are fixedly arranged in the detection box 100 through columns 408. The driving motor 401 and the bearing seat 403 are fixedly arranged on both sides between the detection box 100 and the mounting base plate 404. One end of the double helical screw rod 402 is drivingly connected to the power output end of the driving motor 401, and the other end of the double helical screw rod 402 can be rotatably placed in the bearing seat 403. Two sliding seats 406 are screwed on the double helical screw rod 402. The two sliding seats 406 move toward or away from each other as the double helical screw rod 402 rotates. The mounting base plate 404 is provided with a screw thread that is aligned with the double helical screw rod 402 up and down. There are two strip-shaped through holes 4041, and the shaping splints are respectively connected to the sliding seat 406 one by one through connecting nails piercing the strip-shaped through holes 4041. The mounting base plate 404 is also provided with a guide rail 407 that slides with the shaping splint. There are two guide rails 407 and they are arranged at intervals. The driving motor 401 drives the double-helical screw 402 to rotate. The double-helical screw 402 has two sections of threads in opposite directions. Since the shaping splint can only slide on the guide rail 407, the shaping splint and the sliding seat 406 are connected by the connecting nails. Therefore, when the double-helical screw 402 rotates, the two shaping splints can only approach each other or move away from each other. When the two shaping splints are close to each other, they can clamp and fix the bagged peritoneal dialysis fluid. When the two shaping splints are away from each other, the bagged peritoneal dialysis fluid can be loosened, so that the bagged peritoneal dialysis fluid can be separated from the shaping splint and rise and fall with the suspension mechanism.

[0039] In an embodiment of the present invention, the shaping splint includes a frame 4051 and a colorless transparent plate 4052 arranged in the frame 4051. The frame 4051 is used to clamp the edge of the bagged peritoneal dialysis fluid. The colorless transparent plate 4052 is preferably a transparent glass plate, which has little effect on light refraction and reflection.

[0040] In an embodiment of the present invention, the optical signal transmitting module includes a first columnar bracket 501 and a light source 502 slidably arranged on the first columnar bracket 501. The light source 502 is used to transmit an initial optical signal to the bagged peritoneal dialysis fluid clamped between two shaping splints. The light source 502 can be a light source of any color, such as a white light source, a red light source, or a green light source. The light source 502 can be an LED light source. As the core component of the optical signal transmitting module, the light source 502 has mature technology and stable performance.

[0041] In an embodiment of the present invention, the projection device 600 is a screen, which can be fixed on the mounting base 404 through a screen frame. Setting the screen can make the intermediate light signal present a bright area and a shadow area, so that the optical signal receiving module can accurately capture the intermediate light signal.

[0042] In an embodiment of the present invention, the optical signal receiving module includes a second columnar bracket 701 and a camera module 702 slidably arranged on the second columnar bracket 701. The camera module 702 can generate an image signal after capturing the intermediate optical signal, and the image signal can be directly input into the analysis module for analysis.

[0043] In the embodiment of the present invention, a display screen 102 is also included which is embedded in the front side of the detection box 100 . The display screen 102 is electrically connected to the analysis module, and the data analyzed by the analysis module can be directly displayed on the display screen 102 .

[0044] In an embodiment of the present invention, a control system is also included. The display screen 102 is a touch screen. The control system is electrically connected to the display screen 102, the optical signal transmitting module, the optical signal receiving module and the analysis module respectively. The detection system can be controlled by operating the display screen 102.

[0045] The detection principle of a peritoneal dialysis machine drainage peritoneal fluid turbidity detection device shown in one embodiment of the present invention is: setting an area threshold, comparing the area of ​​the detection shadow area with the area threshold, when the ratio reaches 0.01, it is judged as slight turbidity, when the ratio is between 0.01-0.1, it is judged as moderate turbidity, and when the ratio is greater than 0.1, it is judged as severe turbidity.

[0046] A peritoneal dialysis machine drainage peritoneal dialysis fluid turbidity detection device according to an embodiment of the present invention, by providing a lifting mechanism 200, the bagged peritoneal dialysis fluid suspended on the suspension mechanism can be placed into and taken out of the detection box 100 without manual operation, and the operation method is simple. By providing a clamping mechanism, the bagged peritoneal dialysis fluid can be made into a regular shape during detection, which helps to improve the detection accuracy; by providing an optical signal transmitting module, a projection device, an optical signal receiving module and an analysis module, the light analysis technology can be used to achieve efficient and accurate detection of the turbidity of the bagged peritoneal dialysis fluid.
