Technical Field

[0001] This application relates to the field of fecal blood detection technology, and in particular to a method, device and system for detecting fecal occult blood. Background Technology

[0002] For gastrointestinal bleeding, there are different symptoms such as vomiting blood and bloody stools. Vomiting blood is generally easy to detect and monitor, but bloody stools, especially in the early stages, are often overlooked. This is because patients often simply flush their stools after defecation, and may not notice the blood in time. Even if they do notice it, it often requires taking photos or having medical staff examine the patient on-site. In some cases, medical staff may also have difficulty making an accurate diagnosis, often leading to missing the optimal detection period.

[0003] There is also a test strip for detecting blood in stool in the existing technology, but its operation is also very complicated. It requires the stool to be drawn and dripped onto the test strip, which can easily cause pollution to the surrounding environment.

DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solutions and effects of the present application more clear and explicit, the technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. The described embodiments are only possible technical implementations of the present application, not all possible implementations. Based on the embodiments in the present application, those skilled in the art can combine the embodiments of the present application to obtain other embodiments without creative labor, and these embodiments are also within the protection scope of the present application.

[0044] First, the terms involved in the present application are explained:

[0045] ECP, or Endoscopic Hemostasis Procedure.

[0046] CT lines, Control Line & Test Line;

[0047] HIS system, Hospital Information System.

[0048] In related technologies, patients with gastrointestinal bleeding typically present with either hematemesis (vomiting blood) or melena (blood in stool). Bleeding can be identified by examining the vomit (vomiting blood) or the stool (melena). Currently, many patients do not observe their stool after defecation, flushing it away directly. Doctors and nurses cannot see this, and the patients themselves are unaware that they have passed blood in their stool, thus failing to recognize the presence of bleeding components. Alternatively, patients may only visually inspect the stool, making it impossible to accurately determine the extent of bleeding.

[0049] The current procedure involves instructing patients to check their stool for redness or blackness after endoscopic or ECP procedures and inform the doctor or nurse, or request their assistance. After defecation, some family members take photos and show them to the doctor or nurse. Other patients defecate directly into the toilet or in a bedpan and then request the doctor or nurse to examine it. The nurse also takes photos after reviewing the images. If suspected bleeding is detected, the photos are sent to the doctor, who then assesses the situation to determine if gastrointestinal bleeding is present. Therefore, this process is quite cumbersome.

[0050] To address the issue of low efficiency in stool blood detection caused by patients forgetting to take photos after defecation or failing to allow nurses to observe, this application automates the detection process by converting the excrement into liquid and automatically dripping the liquid into a detection box for testing. The detection results are determined by identifying the collected images, achieving non-invasive and continuous monitoring of stool blood and improving the efficiency and accuracy of stool blood detection.

[0051] Specifically, the present application automatically identifies user excretion completion (through weight sensor or image motion recognition), triggers excretion (feces) conversion and detection process without manual intervention, detects the result in real time and pushes it to the server or medical staff terminal, shortens the time difference from "hematochezia occurrence" to "medical response"; feces is converted into liquid by a closed converter, avoiding environmental pollution caused by manual operation (such as feces residue and test paper pollution), and the test site of the detection box (test paper) is automatically replaced (new test paper is replaced after each detection) to prevent cross contamination; the camera continuously monitors the color change of the test paper, combines with the preset algorithm (such as the color comparison of the quality control area and the test area), accurately judges the positive (hematochezia), negative or invalid result; the multiple test site design supports repeated detection, reduces the accidental error of single detection; the detection result is automatically uploaded to the medical record system to form a dynamic database of the patient's hematochezia situation, supporting historical data comparison and trend analysis.

[0052] The technical solutions of the present application will be described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes may not be described in detail in some examples.

[0053] As shown in Figure 1 The hemoccult detection device described in the preferred embodiment of the present application is used to implement the hemoccult detection method. The hemoccult detection device is installed on a toilet, and the hemoccult detection device includes a processor, a converter 10, a droplet mechanism 20, a detection box 30, and a collection module 40. The processor is connected to the converter 10, the droplet mechanism 20, the detection box 30, and the collection module 40, respectively.

[0054] The processor is used to detect that the user has finished excretion, and the converter 10 is used to convert the excretion into a target liquid. The processor is used to control the droplet mechanism 20 to drop the target liquid into the detection box 30, and the collection module 40 is used to acquire monitoring information within a test time. The processor is used to obtain a detection result of the user according to the monitoring information and send the detection result to a medical record system.

[0055] It can be understood that the identity information of different patients is identified by using visual recognition or electrical signal corresponding sensing recognition, and then the corresponding hemoccult situation is collected and input into the system to form a corresponding database. In the presence of hemoccult, a prompt is sent to medical staff, and the patient's continuous hemoccult situation, hemoccult degree, etc. can be monitored.

[0056] In an embodiment of the present application, the collection module 40 is a camera; the droplet mechanism 20 comprises a driver 21 and a dropper 22, the driver 21 is connected with the lower port baffle of the converter 10, the driver 21 is used to open or close the lower port baffle, the lower port baffle is in communication with the liquid inlet end of the dropper 22 in the open state, and the liquid outlet end of the dropper 22 is oppositely arranged with the detection box 30 arranged obliquely.

[0057] Specifically, the toilet has a feces detection box 30, and some test papers (sensors) are arranged in the detection box 30. The detection result is determined by identifying the color change of the test papers in the detection box 30. The detection box 30 can transmit the detection result to the medical record system, and the detection result can be automatically uploaded after identification. Then the doctor can receive a reminder and directly view the detection result of the user (patient).

[0058] Further, referring to Figure 1 , the camera is arranged on the toilet, and another camera can be arranged in the detection box 30 to collect monitoring images. The driver 21 is connected with the lower port baffle of the feces collection converter 10. The driver 21 is a motor or an electric push rod. The driver 21 drives the lower port baffle to move, so that the lower port baffle is in an open state (in communication with the dropper 22) or a closed state (not in communication with the dropper 22). The converter 10 is designed with a propeller, a high-pressure water gun and a filter screen to mix and stir the feces and water to ensure the uniformity of the sample. The filter screen filters large particle residues to avoid pipe blockage or interference with detection. A plurality of individually packaged fecal occult blood test papers are built-in in the detection box 30. The test papers are placed in a detection position by tearing the package through a roller conveyor or a mechanical arm to ensure that new test papers are used for each detection. The detection box 30 is arranged obliquely corresponding to the vertically arranged dropper 22, so that the detection position of the test paper is designed with an oblique angle to prevent sample diffusion from interfering with the color development reaction and facilitate the liquid in the dropper 22 to be accurately dropped into the detection box 30 for detection.

[0059] Based on the above embodiment, the present application further provides a detection system, wherein the detection system comprises the fecal occult blood detection device as described in the above scheme, and the detection system further comprises a server, and the processor is in communication connection with the server.

[0060] The detection system provided by the present application has all the beneficial effects of the above-mentioned technical solutions, and details are not repeated here.

[0061] The fecal occult blood detection method of the preferred embodiment of the present application, as shown in Figure 2 , comprises the following steps:

[0062] In step S101, when the processor detects that the user has finished discharging, the converter converts the discharge into a target liquid.

[0063] In one possible implementation, in response to an identification operation of the user, the processor determines identity data corresponding to the identification operation; and the processor starts the converter according to the identity data.

[0064] It should be noted that before the detection process starts, the device is started by triggering the user identity recognition, so as to ensure that the detection result is bound to the user identity.

[0065] Specifically, the user completes identity verification by means of card swiping, fingerprint recognition, face recognition, APP binding, or the like (for example, a toilet seat pressure sensor triggers an identification request); the processor receives an identification operation (for example, a scanned user ID) and matches identity information (for example, a name, a medical record number) in a database; and the processor sends a start instruction to the converter according to the matched identity data, and prepares to convert the discharge into a liquid.

[0066] In one possible implementation, the collection module acquires image information of the user and sends the image information to the processor, and if the processor confirms a standing-up action of the user according to the image information, it is determined that the user has finished discharging; or the processor acquires weight data in the converter, and if the weight data remains unchanged within a preset time, it is determined that the user has finished discharging.

[0067] Specifically, whether the user has finished discharging is determined by two independent manners to trigger a subsequent detection process. Manner one (image monitoring), a camera continuously acquires user images and transmits the images to the processor, and the processor identifies user actions (for example, standing up and leaving a toilet seat) by means of image algorithms, and if a standing-up action is detected, it is determined that the discharging is completed. Manner two (weight monitoring), a weight sensor is built in the converter to monitor the weight of the discharge in real time; and if the weight data does not change within a preset time (for example, 30 seconds), it is determined that the discharging is completed.

[0068] In one possible implementation, the processor sends a conversion signal to the converter, and the converter converts the discharge into a target liquid according to the conversion signal.

[0069] Specifically, solid discharge is converted into a liquid for subsequent drop detection. After confirming that the discharging is completed, the processor sends a conversion signal to the converter, and the converter converts the solid discharge into a uniform liquid by means of mechanical crushing, stirring, adding a solvent (for example, water or a buffer), or the like, and feeds back a conversion completion signal to the processor to enter a drop stage. When the conversion is performed, it is necessary to ensure that the discharge is fully liquefied and uniform, so as to avoid detection errors of test paper caused by solid particles.

[0070] In step S102, the processor controls the droplet mechanism to drop the target liquid into the detection box, and the acquisition module acquires monitoring information within a test time.

[0071] In a possible implementation, the monitoring information includes a plurality of monitoring images. The processor acquires a current content of the target liquid in the converter, controls the droplet mechanism to release a set content of the target liquid from the converter to the detection box if the current content meets a preset requirement, and sends a shooting signal to the acquisition module; and the acquisition module acquires a plurality of monitoring images of the detection box within a test time according to the shooting signal.

[0072] Specifically, the processor monitors the residual amount of the target liquid (liquid B converted from excrement) in the converter in real time through a built-in sensor (such as a liquid level sensor), ensures that there is enough sample amount for subsequent droplet operation, and avoids detection failure (such as insufficient reaction of test paper) due to insufficient liquid. The minimum liquid amount required for droplet is set in advance, and if the current content is greater than or equal to the minimum amount, the droplet is executed; if the current content is less than the minimum amount, a "sample insufficient" prompt is triggered (such as sending a reminder to the user or medical staff). The processor sends an instruction to the droplet mechanism (such as a micro pump or a valve) to extract a set amount of liquid from the converter and accurately drop it into the idle test paper test site of the detection box through the pipeline, wherein the detection box is built-in with a plurality of independent test sites, one unused test site is used for each detection to avoid cross contamination, and after each detection is completed, the test site is automatically rotated or moved to the next idle position to ensure that new test paper is used for the next detection.

[0073] After the droplet is completed, the processor immediately sends a start shooting signal to the camera, the camera enters a working state, continuously shoots within a test time, shoots one image at a preset interval, finally acquires a plurality of monitoring images, captures the dynamic process of color change of the test paper (such as the color gradient of the quality control area and the test area) through multiple images, and avoids accidental errors (such as instantaneous color when the test paper is not completely reacted) of single shooting.

[0074] In step S103, the processor obtains a detection result of the user according to the monitoring information, and sends the detection result to a server.

[0075] In a possible implementation, the detection result includes positive, negative, or invalid. Bit line color data is obtained according to a plurality of monitoring images; if the bit line color data includes quality control area change data and test area change data, it is determined that the detection result of the user is positive; if the bit line color data is only the quality control area change data, it is determined that the detection result of the user is negative; and if the bit line color data is only the test area change data, it is determined that the detection result of the user is invalid.

[0076] Specifically, the processor performs image algorithm analysis on the plurality of monitoring images stored by the acquisition module, extracts color change data of the test paper quality control area (C line) and the test area (T line); preset color change thresholds of the C line and the T line, and confirm whether the color change is stable (such as the color of the T line continuously deepens within the test time) through comparison of multiple images.

[0077] The image is collected between 5-10 minutes after the detection starts to detect the interpretation result, refer to Figure 3 , positive, indicating that the concentration of human hemoglobin in the sample is above 100 ng / ml, two purple-red bands appear, one in the test area (T), and the other in the quality control area (C); negative, indicating that the concentration of human hemoglobin in the sample is below 100 ng / ml, a purple-red band appears in the quality control area (C), and no purple-red band appears in the test area (T); invalid, the quality control area (C) does not appear a purple-red band, indicating that the test is invalid, and the detection should be performed again.

[0078] The processor binds the determination result (positive / negative / invalid) with the user identity data and the detection timestamp to form structured data.

[0079] In one possible implementation, when the bit line color data does not show the quality control area change data and the test area change data, the processor determines that the detection result of the user is negative, and if the detection result is negative, the detection cartridge is replaced for the next detection; if the detection result is positive, the processor sends a reminder information to the user.

[0080] Specifically, when the effective color data of the C line and the T line cannot be extracted (such as the test paper not being in contact with liquid, camera failure or environmental light interference), if there is no change in the C line and the T line, the default detection result is negative (to avoid false negatives, but the validity of the test paper needs to be further verified); if only the T line changes and the C line does not change, it is determined to be invalid (the quality control area is invalid, and the result is not reliable). The detection cartridge is built-in with multiple independent test sites, which automatically switches to the next idle test site after each detection through mechanical structure, to ensure that new test paper is used for the next detection.

[0081] The specific implementation of the present application will be described below in combination with a specific application scenario.

[0082] Step K1, information collection;

[0083] Step K2, convert the feces into liquid B through the stool collection converter A;

[0084] Step K3, drop the liquid B on the idle test paper test site (replace the test paper automatically after each test, and there are multiple test sites) through a pipe or other method;

[0085] Step K4, the blood stool test device (test box) is equipped with a camera or the camera is installed on the closestool, the camera monitors the test paper position all the time, detects the state of the test paper in the test paper position, and judges the abnormality by judging the color change of the test paper CT position line through image algorithm;

[0086] Step K5, if abnormal phenomenon occurs within the test time, the abnormal state is judged and pushed to the server, service station, relevant personnel, etc., no abnormal phenomenon is judged within the timeout, which is the normal state, and normal data is also pushed to the server, service station, relevant personnel, etc., and the test paper is automatically replaced when the timeout.

[0087] Step K6, the abnormal and normal messages in step K5 are pushed mainly for analyzing the blood stool probability, so as to facilitate the medical staff and other relevant personnel to view.
