Description

Technical Field

[0001] The present disclosure relates to the technical field of clinical information recording, and in particular to a clinical patient 24-hour inflow and outflow statistics system, a clinical patient 24-hour inflow and outflow statistics method and an electronic device. Background Art

[0002] The 24-hour intake and output recording method is mainly used to record the amount of fluid a patient ingests and excretes within 24 hours, providing a very important basis for doctors to understand the patient's body fluid balance. The 24-hour intake and output recording method includes intake recording and output recording. Use a cup with a capacity scale mark to measure the amount of water or beverages entering the patient's body. Use appropriate measuring tools such as a measuring cup or a measuring cylinder to measure the output and record it in a timely manner. Use a blue-black pen or a carbon steel pen to record from 7 a.m. to 7 p.m., and use a red pen to record from 7 p.m. to 7 a.m. the next morning. The summary of fluid intake and output should be made on time, and a 24-hour summary should be made at 7 a.m. the next morning. Through the above recording methods and precautions, the patient's 24-hour intake and output can be correctly recorded. The contents of clinical intake and output records mainly include:

[0003] 1. Fluid intake, including the amount of fluid ingested, the water "hidden" in food, the water produced by metabolism (including protein - 40mV100g, fat = 100mV100g, carbohydrates - 100mI100g), and the therapeutic amount (such as the amount of infusion);

[0004] 2. Fluid output, including urine volume, insensible loss of water (including water lost through respiratory evaporation and sweating and evaporation from the skin surface, about 750ml-1000mld), water in feces (about 150mi / d), amount of bleeding, drainage, wound exudate, vomitus, diarrhea, etc.

[0005] The existing clinical records of 24-hour intake and output are mainly based on the doctor's Figure 1 The scale of "Water Content of Commonly Used Foods in Hospitals" shown in the figure manually records the patient's 24-hour intake and output of food and fluids, and requires manual recording of the corresponding food type, time of eating, weight, and water content of food converted according to the scale on the 24-hour intake and output record sheet. However, this manual recording method requires doctors to record each patient 24 hours a day, and they need to record in shifts, which takes up a lot of doctors' working time, and it is often easy to miss or record incorrectly, resulting in the risk that subsequent clinicians cannot correctly assess the patient's body fluid balance, electrolyte status, and nutritional status.

[0052] Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0053] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0054] In addition, in order to better illustrate the present disclosure, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present disclosure.

[0055] Example 1

[0056] like Figure 1 As shown in the figure, it is a table of water content of commonly used foods in hospitals. You can configure the table in the background in advance, or you can build its table content into a MYSQL database to store the corresponding relationship between different food types and water content. It is convenient to perform SQL retrieval based on food type to obtain the water content of the corresponding food.

[0057] like Figure 2 As shown, on one hand, the present application proposes a clinical patient 24-hour inflow and outflow statistics system, comprising:

[0058] An image acquisition system is used to collect images of food currently eaten by clinical patients and upload them to a backend server;

[0059] The backend server is used to identify the food type of the food image and count the corresponding food water content based on the commonly used food water content table in the hospital; and, in combination with the clinical examination or physiological data of the clinical patient recorded in the HIS medical record system, record the clinical patient's intake data and output data within 24 hours respectively;

[0060] PDA terminal, used to log in to the backend server and view the clinical patient's intake and output data within 24 hours;

[0061] The image acquisition system and the PDA terminal are respectively connected to the background server for communication.

[0062] This system aims to input basic data of gram weight and water content of common objects according to the commonly used food water content table. When the patient eats a certain food, the weighed number of grams is entered and automatically converted into water content. The program records the type of food, time of meal, gram weight, and calculates the corresponding water content of the food, and selects the accumulation amount according to different time periods of 12 hours and 24 hours.

[0063] The system can set up custom programs and add food types as needed. After merging with hospital programs, it can automatically capture the amount of arterial and venous fluids such as infusion volume and blood transfusion volume, and then accurately record the intake volume.

[0064] For the calculation of output, you can add urine volume, feces volume, drainage tube drainage volume, and sweat volume (degree of clothing soaking or number of clothes changed) according to your own needs.

[0065] Specific:

[0066] When the patient is eating, the image acquisition system, such as the communication camera or wireless camera set up in the hospital clinic or cafeteria, can collect the food currently eaten by the clinical patient, and upload the physical image taken to the backend server. At the same time, the head portrait of the current clinical patient will also be uploaded. The backend server can use the image recognition system deployed thereon (the application software of the image recognition system, which is installed by itself) to perform image recognition, so as to identify the identity information of the current clinical patient and the type of food currently eaten. Therefore, the type of food eaten by the clinical patient currently eating can be recorded in the patient feeding management system. At the same time, the water content corresponding to the food type can be obtained by SQL retrieval in a pre-set water content table or water content retrieval database.

[0067] As for the examination or physiological data of clinical patients, for example, the intake data of infusion or blood transfusion, or the output data of urination, defecation, drainage or sweat of clinical patients, they can be collected through the HIS medical record system or other terminal systems. The HIS system allows medical staff to dynamically add the corresponding clinical examination or physiological data of clinical patients. Therefore, when the patient's food intake management system records the 24-hour intake and output, it can combine the clinical examination or physiological data at the corresponding time point to visualize the patient's body intake and output data during the treatment or non-treatment stage.

[0068] As an optional implementation scheme of the present application, optionally, the PDA terminal is further used for:

[0069] Every 6-12 hours, the output image data recorded on the preset output registration chart of the clinical patient within 24 hours is photographed and uploaded to the backend server, which recognizes the output registration chart and extracts the output data of the clinical patient within 24 hours.

[0070] A 24-hour output registration chart as shown in Service 3 can record the patient's output data at different time points.

[0071] Medical staff can log into the backend through the PDA terminal to record the amount of infusion, blood transfusion, etc. of clinical patients in the HIS medical record system.

[0072] As for the patient's urine output, defecation volume, drainage volume, etc., a 24-hour output registration chart designed by this solution can be used, and clinical patients can register each time they output (urination or defecation, etc., which can be recorded on the APP or the chart they carry). When medical staff go to work later, they can use the PDA terminal to take a photo of the chart and upload it to the background server, which will then perform image recognition to identify the patient's identity information, head portrait, and output data such as urination or defecation, so as to quickly and effectively obtain the clinical patient's output data within 24 hours and write it into the system.

[0073] Therefore, by using this system, it is possible to realize the automated clinical recording of body intake and output in a lightweight manner, which can facilitate doctors to evaluate patients' fluid balance, electrolyte status and nutritional status, save doctors' recording time, improve work efficiency, and help monitor patients' water intake and output. By recording these data, doctors can determine whether patients have dehydration, excessive intake or electrolyte imbalance, and adjust treatment plans accordingly.

[0074] As an optional implementation scheme of the present application, optionally, the feed data includes:

[0075] The type of food eaten, the time of eating, the weight of food eaten, and the water content of food eaten.

[0076] As an optional implementation scheme of the present application, optionally, the output data includes:

[0077] Urine output, bowel movement, drainage volume, and sweat volume.

[0078] The collection methods and corresponding conversion relationships of the above different types of inflow and outflow can be formulated by the hospital. If there is a specific sampling method, refer to its specific clinical data counting method, such as infusion volume.

[0079] As an optional implementation scheme of the present application, optionally, the background server is deployed with:

[0080] Processors, used to provide data processing and analysis services;

[0081] An image recognition system, used to identify the food type in the food image through a preset hospital food intake recognition model, and send the identified food type to a patient food intake management system;

[0082] The patient feeding management system is used to generate an SQL search instruction for the food type, and search in the water content table of commonly used foods in the hospital to find the water content of the food corresponding to the food type and write it into the feeding record system;

[0083] An intake recording system, used to record the intake data of clinical patients within 24 hours;

[0084] Output recording system, used to record the output data of clinical patients within 24 hours;

[0085] The image recognition system, the patient eating management system, the intake recording system and the output recording system are respectively connected to the processor for communication.

[0086] The image recognition system can be any image recognition software installed by the administrator, which can recognize the patient's head and identify and extract the content of chart information. Please understand and implement it in combination with existing image recognition technology or chart recognition technology.

[0087] The present invention adopts a recognition model to identify different types of food, and can use this model to identify the type of physical object when the image recognition system performs image recognition. Specifically, various foods in the water content table of commonly used foods in hospitals can be used to prepare corresponding image sets, and convolutional neural network models, etc. can be used to train and learn different types of food image features (specifically, CNN image training and learning technology can be combined), so as to construct an AI model that can identify the types of food eaten in different hospitals, and deploy the background after verification. After the image recognition system performs identity recognition such as head portraits (character head portrait recognition software), the hospital eating recognition model can be used to identify and output the food type of the food image eaten by the current patient, and then the patient eating management system records the type of food eaten by the current patient.

[0088] Furthermore, the patient's food intake management system generates a search instruction for retrieving the food type, and retrieves the water content of the food type in the water content table or the corresponding database, and writes it into the system to bind it with the identity of the current clinical patient.

[0089] The intake and output recording systems can read and share the corresponding data from the patient myopia management system, so they can separately record the intake and output data of clinical patients within 24 hours. After logging in through the PDA, the back-end medical staff can view different data from the intake and output recording systems respectively.

[0090] As an optional implementation scheme of the present application, optionally, the background server is also deployed with:

[0091] HIS medical record system is used to record clinical examination or physiological data of clinical patients, including: arterial and venous infusion volume or blood transfusion volume;

[0092] The HIS medical record system is communicatively connected with the processor.

[0093] As an optional implementation scheme of the present application, optionally, the background server is also deployed with:

[0094] A data configuration module, used for customizing the addition of food types and configuring the water content of the added food types in the commonly used food water content table in the hospital;

[0095] The data configuration module is in communication with the processor.

[0096] As an optional implementation scheme of the present application, optionally, the background server is also deployed with:

[0097] Message middleware, used for message forwarding between the backend server and the PDA terminal;

[0098] The message middleware is communicatively connected with the processor.

[0099] The HIS medical record system is a regular application system on the background, which can be used to record clinical treatment data. Therefore, the corresponding clinical examinations or physiological data can be recorded by the corresponding medical staff logging into the background.

[0100] The data configuration module is mainly used for corresponding custom information configuration. Medical staff can log in to the background through PDA and enter the data configuration module to perform corresponding custom operations. For example, they can add new food types to the commonly used food water content table in the hospital and add the corresponding food water content to add new foods.

[0101] The message middleware can use the message queue mechanism to receive and send messages. For example, you can understand it by combining the principle of the KAFKA message queue mechanism.
