TECHNICAL FIELD
[0001] The present application relates to the technical field of medical detection, in particular to a quantitative evaluation device and method for blood urine detection. BACKGROUND
[0002] Hematuria is one of the most common symptoms of urinary system diseases, and accurate judgment of the degree of hematuria is of great significance for diagnosis, treatment and prognosis of diseases. There are three main methods for judging the degree of hematuria in clinical practice: one is the naked eye observation method, which is subjective and not accurate enough; the second is the hematuria colorimetric card method, which is more accurate than the naked eye observation, but is still a subjective judgment in nature, and is easily disturbed by environmental and lighting factors, and is also time-consuming in operation; the third is the laboratory examination method, which is relatively accurate, but it is difficult to achieve rapid evaluation due to the long time required.
[0003] Therefore, the present application aims to provide a quantitative evaluation device and method for blood urine detection to solve the above problems. SUMMARY
[0004] The purpose of the present application is to solve the above problems, and to provide a quantitative evaluation device and method for blood urine detection, which utilizes spectrophotometric colorimetric technology to obtain light transmitted through the drainage pipeline through a sensor, combines advanced image processing algorithms and spectral analysis technology, and realizes quantitative evaluation of the degree of hematuria.
[0005] In order to achieve the above purpose, the technical scheme of the present application is as follows:
[0006] The present application provides a quantitative evaluation device for blood urine detection, which is a clamp-type blood urine detector, the clamp-type blood urine detector body comprises a pair of clamps, a pair of clamping arms, a pair of clamping handles and a connecting device,
[0007] The clamps are connected with the clamping arms, the clamping arms are connected with the connecting device, and the connecting device is connected with the clamping handles; the pair of clamping arms are respectively embedded with a light sensor, a processing chip, a photoelectric receiver and a display screen.
[0008] The clamping arms are circular arc clamping arms, one of the clamps, one of the clamping arms and one of the clamping handles are integrally formed to form a clamping pipe, the light sensor is embedded in the inside of one of the clamping pipes, and the processing chip, the photoelectric receiver and the display screen are embedded in the inside of the other clamping pipe. Among them, the light sensor and the photoelectric receiver are located on the same horizontal line.
[0009] The connecting device comprises a metal movable pin and a spring, the spring is fixed in the clamping pipe, the clamping arms and the clamping handles are connected, and the metal movable pin passes through the spring to connect the pair of clamping pipes.
[0010] The assessment method is as follows: A urine sample is collected from the patient into a urine collection bag to obtain a liquid urine sample. A clamp-on hematuria detector is placed on the drainage tube of the urine collection bag. Light is captured by a photosensitive sensor on the clamp arm of the clamp-on hematuria detector and transmitted to the drainage tube, while a photodetector on the other clamp arm receives the residual light after absorption by hemoglobin. Combined with advanced image processing algorithms and spectral analysis technology, a real-time quantitative assessment of the degree of hematuria is achieved.
[0011] In this solution, the clamp-type hematuria detector is located on the drainage tube below the urine collection bag. Light is captured by a photosensitive sensor on the clamp arm of the clamp-type hematuria detector and transmitted to the drainage tube. Meanwhile, a photodetector on the other clamp arm receives the residual light after it has been absorbed by hemoglobin and converts the residual light signal into an electrical signal. The electrical signal is then transmitted to the processing chip. Through advanced image processing algorithms and spectral analysis technology in the processing chip, the degree of hematuria is quantitatively assessed. The assessment results are displayed on a micro-display screen, enabling bedside, non-invasive, continuous, and real-time monitoring.

By integrating advanced image processing algorithms and spectral analysis technology, it achieves a quantitative assessment of the degree of hematuria. Users simply need to clip the detector onto the drainage tube as instructed to obtain information on the degree of hematuria in a short time. The operation is simple, results are obtained quickly, and data can be displayed intuitively. At the same time, it improves the accuracy and objectivity of the judgment, helps nurses to make judgments more conveniently, calms patients' emotions, reduces nurses' workload, and provides stronger diagnostic support for clinicians.

Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort should fall within the scope of protection of the present invention.
[0019] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the embodiments.
[0020] Example:
[0021] The present invention provides a quantitative assessment device and method for hematuria detection, as described above. The device is a clamp-type hematuria detector, the main body of which includes a pair of clamps 1, a pair of clamp arms 2, a pair of clamp handles 3, and a connecting device.
[0022] The clamp 1 is connected to the clamp arm 2, the clamp arm 2 is connected to the connecting device, and the connecting device is connected to the clamp handle 3; a pair of clamp arms 2 are respectively embedded with a light sensor 5, a processing chip 6, a photoelectric receiver and a display screen 8.
[0023] The clamping arm 2 is an arc-shaped clamping arm 2. A clamping head 1, a clamping arm 2, and a clamping handle 3 are integrally formed to constitute a clamping tube component. One clamping tube component embeds the optical sensor 5 inside, and the other clamping tube component houses the processing chip 6, photoelectric receiver, and display screen 8 inside. The optical sensor 5 and the photoelectric receiver are located on the same horizontal line. A silicone anti-slip strip is provided on the inner side of the clamping arm 2 to prevent the clamping tube hematuria detector from slipping off the urine collection bag drainage tube.
[0024] The connecting device includes a metal movable pin 9 and a spring 4. The spring 4 is fixed in the clamping fitting. At the junction of the clamping arm 2 and the clamping handle 3, the metal movable pin 9 passes through the spring 4 to connect a pair of clamping fittings.
[0025] The method is as follows:
[0026] S1. Collect the patient's urine sample into a urine collection bag to obtain a urine liquid sample.
[0027] S2. Place the clamp-type hematuria detector on the drainage tube of the urine collection bag. The light is obtained by the light sensor on the clamp arm of the clamp-type hematuria detector and transmitted to the drainage tube. The photodetector on the other clamp arm receives the residual light after it has been absorbed by hemoglobin. Combined with advanced image processing algorithms and spectral analysis technology, the degree of hematuria can be quantitatively assessed.
[0028] When operating the device using the above embodiments of the present invention, a patient's urine sample is collected into a urine collection bag to obtain a urine liquid sample. A clamp-on hematuria detector is placed on the drainage tube of the urine collection bag. The clamp arm of the clamp-on hematuria detector is equipped with a highly sensitive light sensor, which accurately captures light and emits it into the drainage tube. Simultaneously, a photodetector on the other clamp arm receives residual light that is not absorbed by hemoglobin and efficiently converts the residual light signal into an electrical signal. The converted electrical signal is then transmitted to the built-in processing chip.
[0029] The processing chip incorporates advanced image processing algorithms and spectral analysis technology. These technologies enable in-depth analysis and processing of transmitted electrical signals. By calculating peripheral light intensity, the concentration of hemoglobin in urine can be determined, thereby estimating the degree of hematuria and achieving a precise quantitative assessment of its severity. Ultimately, the assessment results are clearly displayed directly on a micro-display screen, allowing medical staff to quickly and intuitively understand the patient's hematuria status. This improves the convenience and accuracy of hematuria detection, providing strong support for clinical diagnosis and treatment.
[0030] The above specific embodiments are merely explanations of the present invention and are not intended to limit the present invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
