Description

Technical Field

[0001] This invention relates to a supporting device and method for intelligent decision-making in blood transfusion. Background Technology

[0002] Rational blood use has always been a key focus in clinical blood transfusions. Inadequate standardization of clinical blood use leads to blood waste. Currently, the system's control over blood application is not strict, merely managing procedural steps; doctors mostly rely on their own experience and knowledge to make judgments. Standardizing blood use from the clinical application stage and improving clinicians' blood management skills can fundamentally reduce blood waste and significantly improve the situation.

[0003] With the gradual maturation of big data technology in recent years, how to solve these clinical problems through big data analysis and processing methods such as data mining and machine learning, and maximize the use of limited blood resources to better serve clinical practice, has become an urgent technical problem to be solved, and has very important clinical value and social significance.

[0004] Blood transfusions can save lives, but they can also cause serious harm, potentially leading to adverse reactions or even death. When administering blood transfusions, it is crucial to adhere to the principles of transfusion therapy, strictly control the scope of its application, and resolutely avoid transfusions whenever possible, minimizing transfusions whenever possible.

[0005] On the other hand, blood shortages have become the norm in major medical institutions. Blood has a short shelf life, and during storage, the amount of voluntary blood donations is unknown, and the amount of blood needed for clinical use is difficult to predict. Therefore, there is an urgent need to adopt new technologies to help resolve this contradiction. For example, by predicting the blood usage of individual cases and hospitals, the entire blood supply can be monitored, ensuring that clinicians have a clear understanding of blood reserves. This allows for more rational planning of inventory levels and enables comprehensive management of the entire process from blood collection and storage to its use.

[0006] Furthermore, since existing blood transfusions require reasonable control of limited blood supply to avoid inefficient use, the proper dispensing, recycling, and temporary storage of blood are particularly important. This invention reduces human intervention and achieves pretreatment of blood to ensure it is not contaminated, allowing it to be temporarily stored for future use. Summary of the Invention

[0007] The technical problem this invention aims to solve is, in general, to provide an intelligent blood transfusion decision-making system and method. The solution of this invention involves: using hospital electronic medical record data as the retrieval object, developing a retrieval algorithm, and employing big data analysis methods to achieve precise retrieval of the electronic medical record data, forming a blood transfusion clinical manifestation database. Based on the patient's basic hospitalization information, current indications, and the blood transfusion clinical manifestation database, the system guides clinicians on whether the patient should receive a blood transfusion, what type of blood should be transfused, and how much blood should be transfused, thus achieving simple and intelligent blood transfusion. The parent application number is 202010360061.4; the invention title is "Intelligent Blood Transfusion Decision-Making System, Device, and Method"; the application date is 2020-04-30.

[0008] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0009] A blood transfusion intelligent decision-making support device, including

[0010] A conveyor belt connects to the hospital's blood bank at one end and to the nurses' station at the other. A robotic arm in the blood bank delivers the required blood bags to the nurses' station via the conveyor belt. The nurses then administer the blood bags to the patients via IV tubing according to their needs.

[0011] Conveyor belt deflectors are distributed laterally on the conveyor belt, with spacing greater than the width of the blood bag, so that the blood bag can be placed between adjacent conveyor belt deflectors.

[0012] The lower support rollers are distributed parallel to the conveyor belt direction below the conveyor belt. A gap is provided between the upper surface of the lower support rollers and the lower surface of the conveyor belt for the passage of the blood bags by the conveyor belt baffles. The conveyor belt baffles lift the blood bags containing the remaining blood located on the lower support rollers. The blood bags containing the remaining blood are located between adjacent conveyor belt baffles. The conveyor belt baffles transport the blood bags containing the remaining blood on the lower support rollers.

[0013] The connecting rotating roller is located below the conveyor belts where the two ends are connected, and it carries the blood bag containing the remaining blood forward.

[0014] A temporary storage output belt, whose input end connects to the output end of the lower support roller, is used to receive blood bags with remaining blood sent out by the conveyor belt deflector. The temporary storage output belt is sequentially equipped with a sterilizer for disinfecting the blood bags with remaining blood, a labeling machine for applying smart labels to the surface of the blood bags with remaining blood, and a sealing device for secondary sealing of the blood bags. The sealing device includes a sealing clamping robot and a sealing thermoforming machine. The sealing clamping robot aligns the outer plastic sleeve of the blood bag; the sealing thermoforming machine seals the aligned outer plastic sleeve.

[0015] The output station is located at the output end of the upper section of the conveyor belt and inside the nurse station; a post-output push rod and a front-output platform are respectively set on both sides of the output station so that the post-output push rod can horizontally deliver the blood bag to the front-output platform for the nurse to pick up;

[0016] The placement station is located at the input end of the downward section of the conveyor belt and inside the nurse station; a placement platform is provided on one side of the input end of the downward section of the conveyor belt so that nurses can place blood bags containing remaining blood; a placement pusher is provided on one side of the placement platform so as to push the blood bag to the input end of the lower support roller;

[0017] The blood bag is equipped with a cap for inserting a needle to deliver blood. An outer plastic sleeve, longer than the cap, is fitted over the cap and sealed to the outer surface of the blood bag. Before the blood bag is used, a primary sealing port is provided at the end of the outer plastic sleeve. When in use, the primary sealing port is removed to allow the needle to be inserted into the cap. When the blood bag contains residual blood and needs to be temporarily sealed, it is sealed by the outer plastic sleeve.

[0018] A blood transfusion intelligent decision-making support method, with the aid of a blood transfusion intelligent decision-making support device, includes the following steps;

[0019] Step one: First, the blood bank, based on blood demand, delivers temporary storage freezers or new blood bags to the conveyor belt manually or robotically. Then, the conveyor belt delivers the blood bags to the nurses' station. Next, a pusher pushes the blood bags horizontally to the pre-discharge platform for nurses to retrieve. If the blood bag needs to be used immediately, it is directly transfused to the patient. If the blood bag is not used immediately, proceed to step two.

[0020] Step two: First, hang the blood bag on the top hook of the top rack, measure its weight using a gravity sensor and convert it to volume. Then, hang the dispensing bag on the middle hook of the middle rack, measure its weight using a gravity sensor and convert it to volume. Next, open the primary sealing port, connect the main distribution tube to the upper end of the dispensing bag through the blood distribution branch tube, insert the needle of the main distribution tube into the bag cap through the outer plastic sleeve, and adjust the flow rate using the blood clamp. Replace the blood bag with a new one when the blood bag is used. When the dispensing bag is filled to the set threshold, close the blood clamp, and the dispensing bag is used for patient infusion. After dispensing, if there is residual blood in the blood bag, remove the blood bag and place it on the placement platform. Place the push rod to push the blood bag to the input end of the lower support roller.

[0021] Step 3: The conveyor belt pusher moves the blood bag forward on the lower support roller, and through the connecting rotating roller, it moves the blood bag forward below the junction of the two ends of the conveyor belt until it is on the temporary storage output belt.

[0022] Step four: On the temporary storage output belt, firstly, the blood bags are disinfected by a sterilizer; then, a labeler applies a smart label to the surface of the blood bags; secondly, a sealing and clamping robotic arm clamps the outer plastic sleeve exposed on the bag cap, while a sealing thermoforming machine heats the outer plastic sleeve to perform a secondary seal, preventing the bag cap from being exposed.

[0023] Step five: First, the temporary storage pusher pushes the blood bag away from the temporary storage output belt; then, the refrigeration robot stores the blood bag output from the temporary storage output belt into the matrix drawer of the temporary storage refrigerator for future use. For transfusion decision-making, clinicians select the patient's basic information and clinical symptoms to obtain a system-recommended transfusion treatment plan; this solves the technical problem of clinicians lacking sufficient understanding of relevant standards and knowledge regarding transfusion treatment plans, and not knowing how to apply for blood transfusions.

[0024] This invention is reasonably designed, low in cost, sturdy and durable, safe and reliable, simple to operate, time-saving and labor-saving, cost-saving, compact in structure and easy to use. Attached Figure Description

[0035] Conveyor belt deflectors 2 are laterally distributed on the conveyor belt 1, with their spacing greater than the width of the blood bag 5, so that the blood bag 5 can be placed between adjacent conveyor belt deflectors 2.

[0036] The lower support roller 8 is distributed parallel to the conveyor belt 1 below the conveyor belt 1. A gap is provided between the upper surface of the lower support roller 8 and the lower surface of the conveyor belt 1 for the passage of the conveyor belt baffle 2 and the blood bag 5. The conveyor belt baffle 2 lifts the blood bag 5 containing the remaining blood located on the lower support roller 8. The blood bag 5 with the remaining blood is located between adjacent conveyor belt baffles 2.

[0037] The connecting rotating roller 9 is located below the conveyor belt 1 where the two ends are connected, and it carries the blood bag 5 containing the remaining blood forward.

[0038] A temporary storage output belt 10, whose input end is connected to the output end of the lower support roller 8, is used to receive the blood bag 5 with remaining blood sent out by the conveyor belt deflector 2. On the temporary storage output belt 10, there are in sequence a sterilizer 11 for disinfecting the blood bag 5 with remaining blood, a labeling machine 12 for affixing smart labels to the surface of the blood bag 5 with remaining blood, and a sealing device for secondary sealing of the blood bag 5. The sealing device includes a sealing clamping robot 13 and a sealing thermoforming machine 14. The sealing clamping robot 13 aligns the outer plastic sleeve 18 of the blood bag 5. The sealing thermoforming machine 14 seals the aligned outer plastic sleeve 18.

[0039] The output station is located at the output end of the upper section of the conveyor belt 1 and inside the nurse station; an output push rod 3 and an output platform 4 are respectively set on both sides of the output station so that the output push rod 3 can horizontally send the blood bag 5 to the output platform 4 for the nurse to pick up.

[0040] The blood bag 5 is placed at the input end of the downward section of the conveyor belt 1, within the nurse's station. An insertion platform 6 is provided on one side of the input end of the downward section of the conveyor belt 1, allowing nurses to place the blood bag 5 containing remaining blood. An insertion pusher 7 is located on one side of the insertion platform 6 to push the blood bag 5 to the input end of the lower support roller 8. The blood bag 5 has a cap 17 for inserting a needle to output blood. An outer plastic sleeve 18, longer than the cap 17, is fitted over the cap 17 and sealed to the outer surface of the blood bag 5 at its base. Before use, a primary sealing port 19 is provided at the port of the outer plastic sleeve 18. During use, the primary sealing port 19 is removed, allowing the needle to be inserted into the cap 17. When the blood bag 5 contains remaining blood and needs to be temporarily sealed, it is sealed by the outer plastic sleeve 18.

[0041] The intelligent decision-making device for blood transfusion also includes a medicine conveyor belt connected to the pharmacy on the conveyor belt 1; the pharmacy transfers the medicine to the conveyor belt 1 via the medicine conveyor belt, and then the medicine is delivered to the corresponding nurse station via the conveyor belt 1.

[0042] It is set on one side of the output end of the temporary storage output belt 10 to push the blood bag 5 away from the temporary storage output belt 10;

[0043] The temporary storage freezer 16 has a freezer robot arm on one side for storing / retrieving blood bags 5; the freezer robot arm stores the blood bags 5 output from the temporary storage output belt 10 into the matrix drawer of the temporary storage freezer 16, and sends the blood bags 5 in the matrix drawer to the conveyor belt 1.

[0044] The support frame 20 is installed at the nurse station and consists of two layers: a top frame 21 and a middle frame 23. The top frame 21 is equipped with a top hook 22 for hanging blood bags 5 for dispensing upside down.

[0045] The central frame 23 is divided into central hooks 25 connected by gravity sensors 24. A dispensing bag 26 for quantitative blood transfusion to patients is hung on the central hook 25. The dispensing bag 26 is provided with a bag opening and / or a one-way valve 27. The upper end of the dispensing bag 26 is connected to a blood distribution branch tube 28 for inputting dispensing blood. A blood blocking clamp 29 is provided on the blood distribution branch tube 28 to adjust the flow rate and / or start and stop of the input blood. A blood matching plate 30 is provided on the central frame 23, which is connected to the inlet of several blood distribution branch tubes 28. The upper end of the blood matching plate 30 is connected to the bag cap 17 of the blood bag 5 through a main blood distribution tube 31.

[0046] The intelligent blood transfusion decision-making method of this embodiment, with the aid of an intelligent blood transfusion decision-making device, includes the following steps;

[0047] Step 1: First, based on blood demand, the blood bank delivers the temporary storage freezer 16 or new blood bags 5 to the conveyor belt 1 manually or via a robotic arm. Then, the conveyor belt 1 delivers the blood bags 5 to the nurses' station. Next, the output pusher 3 horizontally delivers the blood bags 5 to the output platform 4 for the nurses to retrieve. The nurse retrieves the blood bags 5; if the blood bags 5 need to be used immediately, they are directly transfused to the patient. If the blood bags 5 are not used immediately, proceed to Step 2.

[0048] Step two: First, hang the blood bag 5 on the top hook 22 of the top rack 21, measure its weight using a gravity sensor and convert it to volume. Then, hang the dispensing bag 26 on the middle hook 25 of the middle rack 23, measure its weight using a gravity sensor 24 and convert it to volume. Next, open the primary sealing port 19, connect the main distribution tube 31 to the upper end of the dispensing bag 26 through the blood distribution branch tube 28, insert the needle of the main distribution tube 31 into the bag cap 17 through the outer plastic sleeve 18, and adjust the flow rate using the blood clamp 29. When the blood bag 5 is used to replace the new blood bag 5; when the dispensing bag 26 is filled to the set threshold, close the blood clamp 29, and the dispensing bag 26 is used for patient infusion. After dispensing, if there is residual blood in the blood bag 5, remove the blood bag 5 and place it on the placement platform 6, and place the push rod 7 to push the blood bag 5 to the input end of the lower support roller 8.

[0049] Step 3: The conveyor belt deflector 2 moves the blood bag 5 forward on the lower support roller 8, and through the connecting rotating roller 9, moves the blood bag 5 forward below the junction of the two ends of the conveyor belt 1 until it is on the temporary storage output belt 10.

[0050] Step 4: On the temporary storage output belt 10, firstly, it is disinfected by the sterilizer 11; then, the labeler 12 applies a smart label to the surface of the blood bag 5; secondly, the sealing clamping robot arm 13 clamps the outer plastic sleeve 18 exposed on the bag cap 17, while the sealing thermoforming machine 14 heats and performs a secondary seal on the outer plastic sleeve 18 to prevent the bag cap 17 from being exposed.

[0051] Step 5: First, the temporary storage pusher 15 pushes the blood bag 5 away from the temporary storage output belt 10; then, the refrigeration robot stores the blood bag 5 output from the temporary storage output belt 10 into the matrix drawer of the temporary storage refrigeration cabinet 16 for future use. The conveyor belt 1 enables long-distance transmission, the conveyor belt deflector 2 utilizes the downward section of the conveyor belt to avoid idle travel, greatly saving limited hospital space and facilitating modification. The output pusher 3 and the output platform 4 output the blood bag 5, the placement platform 6 and the placement pusher 7 input the blood bag, the lower support roller 8 provides auxiliary lifting, and the connecting rotating roller 9 ensures continuous transmission and saves power. The temporary storage output belt 10 connects the workstations. Through the sterilizer 11, labeler 12, sealing clamping robot 13, and sealing thermoforming machine 14, secondary processing of the blood bags is achieved, ensuring safety and hygiene and conserving precious blood resources. The temporary storage pusher 15 and the temporary storage refrigeration cabinet 16 provide temporary storage. The bag cap 17, due to its elasticity and the fact that blood coagulates at low temperatures, prevents blood leakage. Of course, the main distribution tube 31 can be retained without removing its needle, and the tube and outer plastic sleeve 18 can be thermoplasticized together for better sealing. The single-use sealing port 19 is convenient and hygienic. The support frame 20, top frame 21, top hook 22, and middle frame 23 facilitate blood dispensing. The gravity sensor 24 detects gravity, avoiding prolonged observation by nurses. When the gravity falls below a set threshold (converted to volume), an alarm or voice prompt reminds the nurse to close the bag promptly. The middle hook 25 allows for hanging. The dispensing bag 26 is used for transfusion to the patient. The one-way valve 27 is an auxiliary device. The blood dispensing branch 28 allows for dispensing multiple bags on one side. The blood clamp 29 is a spring clamp. The blood matching tray 30 provides buffering and dispensing functions. This invention solves the existing blood recycling problem, achieves quantitative blood transfusion, and avoids waste.

[0052] As parallel options, such as Figure 1-8 The present invention includes a doctor user port, a system server and an external port installed in the hospital; its architecture includes a data layer, an interaction layer, an application layer and peripheral system applications;

[0053] In the data layer, the Hospital Information System (HIS) records patient and diagnostic information; the Laboratory / Testing Department Information System (LIS) records blood typing / indication testing information; the Medical Record Record (EMR) system records transfusion medical record information; the Hospital Transfusion Medical Record System (TMIS) records patients' historical transfusion information; and the Medical Treatment Decision-Making (IDT) system records transfusion intelligent decision-making information. Intelligent decision-making: Based on patient information, recommendations for transfusion treatment plans are derived through national transfusion guidelines, transfusion standards, and clinical disease analysis.

[0054] The interaction layer enables data interaction and business logic processing between the data layer and the application layer.

[0055] Based on patient and diagnostic information provided by the HIS system, patient indications provided by the LIS system, clinical symptoms provided by the EMR, patient's historical transfusion information, and transfusion intelligent decision-making information from the IDT system, the data is filtered and calculated.

[0056] The application layer, based on the data and business information transmitted from the interaction layer, formulates a blood transfusion treatment plan by filtering and calculating the information. The blood transfusion treatment plan includes autologous blood transfusion treatment plan and allogeneic blood transfusion treatment plan, which serve as a reference for blood use applications.

[0057] The peripheral system applications submit clinical blood use requests to the blood bank based on the blood use request reference;

[0058] At the application layer, patient information, clinical information, and indications are extracted via an interface or manually entered into the doctor's user port. After the interaction layer retrieves and analyzes the information from the data layer, it recommends a blood transfusion treatment plan for the patient to the doctor's user port. The doctor then decides whether to enable the plan. During use, there are corresponding reminders to assist the doctor in using it correctly.

[0059] The application layer includes an electronic medical record retrieval system, a blood transfusion decision-making system, and third-party embedded function pages; among them...

[0060] The electronic medical record retrieval system performs structured tabular analysis on EMR system data, conducts periodic retrievals, and annotates the retrieval results to form a transfusion manifestation database; the diagnosis and treatment IDT system analyzes hospital electronic medical records based on intelligent decision-making algorithms, annotates the output results, and generates a transfusion manifestation database dictionary.

[0061] The keyword extraction logic of the electronic medical record retrieval system first determines the searchable electronic medical record text by keyword based on inclusion relationships. Then, after identifying the keyword, it checks for negative words such as "none," "not," "nothing," "not," "not seen," "not heard," or "not experienced" before the preceding punctuation mark. If a negative word is found, keywords within the interval between the negative word and the first punctuation mark following it (excluding the comma) are excluded from decision analysis. If no negative word is found, the keyword is used in the decision-making process. During the recommendation process, keywords that are excluded from decision-making and display negative meanings can be added. Specifically, the punctuation marks excluding the comma are identified as: period, comma, semicolon, question mark, colon, exclamation mark, and colon. These represent Chinese and English characters, respectively.

[0062] The intelligent decision-making algorithm employs a hedging algorithm.

[0063] To perform hedging A, firstly, based on the patient's transfusion medical record A1, the pre-transfusion ward round performance A2 and discharge performance A3 are used to derive transfusion performance information A4, excluding non-transfusion performance such as surgery; then, the indication enhancement coefficient A7 is derived based on the transfusion record performance A5 and the recorded post-transfusion evaluation A6.

[0064] To perform hedging B, firstly, hedging analysis B3 is performed between the pre-transfusion ward round performance B11 based on transfusion medical record B1 and the complete ward round performance B21 based on non-transfusion medical record B2, resulting in transfusion performance B4.

[0065] To perform hedging C, firstly, based on the pre-transfusion ward round performance C2 of the patient's transfusion medical record C1, calculate the number of repetitions C3 for each performance and manually label it Y / N;

[0066] The transfusion performance information A4, the indication enhancement coefficient A7, and the transfusion performance B4 were calculated. The number of repetitions for each performance was D1, and the non-repetitions were manually labeled Y / N after screening.

[0067] The data after manually marking Y / N will be included in the system's performance dictionary;

[0068] Scenario 1: Judging the meaning of negation:

[0069] For example: Nervous system: No headache or dizziness (keywords indicating negative secondary clinical manifestations should not be captured).

[0070] The blood transfusion decision system retrieves data from the diagnostic IDT system to guide patients' blood transfusion decisions; it integrates basic patient information, test indicators, clinical manifestations, and the backend blood transfusion indicator and transfusion performance database to provide doctors with reasonable guidance on blood use;

[0071] The blood transfusion decision embedding page allows third-party systems to call and embed it into the blood transfusion decision system, enabling blood transfusion decision guidance and simplifying doctors' operations; after moving from the HIS embedding page of the HIS system to the decision page, patient information and LIS information are retrieved, the results are automatically saved, and records are generated on the list page;

[0072] The clinical physician user portal is installed on the PC used by the clinician. The blood transfusion decision system assigns each clinician a corresponding login number and password. Based on the patient information, the clinician enters the login number, inputs the patient's diagnosis information, retrieves the patient's historical diagnosis information from the electronic medical record retrieval system, and issues a blood transfusion decision.

[0073] The transfusion physician user portal is installed on the PC used by transfusion physicians. The transfusion decision system assigns each transfusion physician a corresponding login number and password. After entering the login number, the transfusion physician enters the patient information, retrieves the patient's transfusion information from the electronic medical record retrieval system, views the transfusion decision process record, and performs statistical analysis.

[0074] The data layer includes a knowledge base containing a basic dictionary, which allows doctors to query transfusion treatment plans or special terms they do not understand through the doctor user portal. The basic dictionary includes blood type, blood variety, clinical diagnosis, primary clinical manifestations, secondary clinical manifestations, clinical manifestations and indications, special markers, special markers and clinical manifestations, blood loss, expected signs, age group, blood volume, transfusion indications, cause dictionary, and age unit.

[0075] The blood transfusion decision system is used by clinicians to view previous blood transfusion decision records. The actors are clinicians and transfusion physicians. It is a preliminary deployment before the doctor makes the actual decision and records the decision record generated after the doctor makes the actual decision.

[0076] The blood transfusion decision-making system displays the decision type, blood volume, decision method, operation time, department, and medical record number for several types of blood; it also removes invalid decision results.

[0077] The transfusion decision analysis includes a year-on-year analysis of the number of decisions made this month, and an analysis of the number of decisions made this month compared to the same month last year; a monthly analysis of decisions and actual transfusions, with major blood types including red blood cells, platelets, plasma, and cryoprecipitate, recording the blood volume determined by the transfusion decision system and the actual blood volume transfused to the patient in the transfusion system; and a monthly transfusion decision ratio analysis, including a comparison between the number of times the patient chose not to transfuse and the number of times the patient chose to transfuse according to the system's decision, as well as a comparison between the number of times the patient made a change in the decision and the number of times the patient transfused according to the system's decision, recording the number of times the patient made a change in the decision and the number of times the patient transfused according to the system's decision.

[0078] Rules for blood transfusion decision analysis

[0079] Red blood cells: body weight (kg) × blood volume (target HB - patient HB) ÷ 25;

[0080] Platelet count in children: (Target platelet count - Patient-indicating platelet count) ÷ 17;

[0081] Platelet count in children: (Target platelet count - Patient-indicating platelet count) ÷ 6;

[0082] Platelet count in infants and young children: (target platelet count - patient's target platelet count) ÷ 60 × weight × 7 ÷ 200;

[0083] Plasma: Body weight × 10;

[0084] Cryoprecipitate (adult): weight ÷ 10 × 4;

[0085] Cryoprecipitate (for infants and young children) × 2;

[0086] The blood transfusion decision system uses integers and 0.5U for blood volume. Values ​​greater than 0.5U are rounded to 0.5U, and values ​​less than 0.5U are rounded to integers. Blood volume less than 0.5U is defined as not recommended for transfusion. Blood volume not less than 0.5U and less than 2U is displayed as a transfusion consideration. Blood volume not less than 2U is displayed as a recommended transfusion.

[0087] If the recommended results have multiple blood categories under the red blood cell category: Blood category priority: washed red blood cells > suspended red blood cells;

[0088] Patient basic information includes medical record number / outpatient number, name, gender, age, region, height (required), weight, blood type, department, bed number, ICD, and clinical diagnosis;

[0089] Patient indications include HB (g / l), hct, platelet count, DIC with fibrinogen level, INR, PT(s), APTT(s), neutrophil count, and blood pressure (mmHg);
