Description

Technical Field

[0001] The present invention relates to the technical field of hospital triage systems, and particularly to an emergency triage system. Background Art

[0002] When seeking medical treatment in the respiratory department or during an epidemic, if a large number of patients are piled up outside the department, there is an infection problem. Existing hospitals use a queuing and calling triage system to improve the efficiency of hospital queuing and calling. The existing automatic triage system includes a server, a switch, a floor switch, and each triage device, and realizes calling through display screens set at various positions. However, when using the existing triage system, there are the following problems: People can only know the calling situation at the position of the display screen. During the epidemic or when an infectious disease breaks out, a large number of people are piled up in the hall with a display screen, which is easy to cause infection. And in the existing triage process, medical staff simply divide patients into several groups according to the severity of their conditions. That is, medical staff use medical evaluations such as blood pressure, pulse, skin color, and general observation of patients to describe the patients' conditions. Then, based on this description and the triage rules of the local hospital, medical staff determine the treatment priority and nursing level. This triage method usually helps the most severely ill people first. However, the problem with this triage method is that although artificial triage is carried out through general observation of patients and triage rules, such information does not establish a widely applicable and consistent judgment process. Medical staff can only judge based on simple patient signs. Even with the guidance of triage rules or guidelines, due to the individual cognition of medical staff, they cannot comprehensively understand the condition of a specific patient. Medical staff may miss the key points of the patient's condition due to carelessness or lack of knowledge, resulting in incorrect triage judgments by medical staff. Therefore, the prior art cannot guarantee the consistency and quality of triage.

[0003] For example, Chinese patent document with publication number CN212381238U discloses a contactless automatic triage system for hospital patients, including a server, a main switch, a floor switch, a triage device, and a medical treatment device. The medical treatment device includes a call device. The triage device includes a management device and a LoRa gateway connected to the management device, and also includes a LoRa terminal. The LoRa terminal includes a controller, a LoRa module, a power module, and a prompt module all connected to the controller. With this system, patients can hold the LoRa terminal and wait for medical treatment in the rest area outside the hospital outpatient building or in a leisure place outside the hospital, realizing decentralized waiting for medical treatment and contactless triage of patients, and avoiding people gathering in the hall to wait.

[0004] However, the invention still has the following technical deficiencies: The LoRa terminals configured in the invention are carried and used by individual users in the hospital. However, since there is a possibility that the users themselves do not comply with the epidemic prevention policies, there are still more users gathering at the same location than the number stipulated by the epidemic prevention policies, resulting in the LoRa terminals still unable to truly achieve uniform dispersion of the user population. In short, even if the crowd does not gather at the display screen for queuing numbers and uses the triage system of the invention, the users will still gather in other areas due to unconsciousness or other reasons, causing a sharp increase in the risk of infectious diseases among people. Therefore, it is necessary to improve the deficiencies of the existing technology.

[0005] In addition, on the one hand, there are differences in the understanding of those skilled in the art; on the other hand, when the inventor made this invention, a large number of documents and patents were studied, but due to space limitations, all the details and contents were not listed in detail. However, this by no means means that the invention does not possess the features of these existing technologies. On the contrary, the invention already possesses all the features of the existing technologies, and the applicant reserves the right to add relevant existing technologies in the background art. Summary of the Invention

[0006] To address the deficiencies of the existing technology, it is proposed to include at least a triage management unit, LoRa terminals, and a server. The server determines, based on the medical factors of the patient, whether the patient needs treatment or outpatient service and assigns a priority to each patient. Among them, the server has at least one triage category database based on patient-stored data and / or patient-derived data. Each triage category is evaluated based on at least one scoring table, and at least one evaluation score is assigned to the severity of the patient's medical condition to receive queries from the server and provide responses. In the present invention, during triage, other information of the patient, such as the triage date and time, the patient's past medical history, age, etc., are all included in the judgment factors. Multiple information of the injured person is input and judged simultaneously. By matching the scoring table with the patient's current state, a predetermined score can be made more quickly and conveniently, so as to perform timely and accurate patient triage allocation.

[0007] According to a preferred embodiment, in the case of triaging a patient, priority selection is performed by using at least one scoring table; wherein, the scoring table specifies at least one medically predetermined characteristic of the patient and at least one standard value related to the patient, and the patient is triaged and allocated. In this case, the present invention triages the patient by using at least one scoring table for priority selection. The scoring table specifies at least one medically predetermined characteristic (such as vital signs, the location or type of trauma, etc.).

[0008] According to a preferred embodiment, several of the said scoring tables assign the severity of the patient's medical condition to several of the said assessment scores, determine the first priority of patient triage based on the assessment scores, and the server generates at least one medical institution scoring table based on different geographical regions and / or processing capabilities of the medical institution to analyze the second priority and calibrate the first priority according to the second priority. By obtaining the second priority based on different geographical regions and / or processing capabilities of the medical institution and calibrating the first priority with this, the present invention can more accurately determine patient triage allocation. Compared with the prior art that simply performs triage based on patient symptoms, the multiple factors considered in the present invention can more accurately reflect the priority of triage required by the patient.

[0009] According to a preferred embodiment, the server updates the at least one medical institution scoring table in a real-time iterative manner and analyzes the second priority. After calibrating the first priority according to the second priority, the LoRa terminal can be called and reminded by medical staff and the real-time position of the LoRa terminal can be located, so as to perform patient triage allocation according to the real-time changes in the triage situation. Such a setting can reduce the amount of data processing and make corresponding adjustments according to the real-time changes in patient symptoms, thereby saving triage time and waiting time.

[0010] According to a preferred embodiment, the system also provides several triage categories, where each triage category is grouped into several hierarchical selections based on the patient's body part and / or injury type, and each of the said hierarchical selections corresponds to one in the triage category; based on the severity of the patient's medical condition, provide at least one selection of the first patient triage category and the second patient triage category from the several triage categories; provide triage classification questions and relevant information for the selected patient classification category and triage the patient. The key point of the present invention is to provide the variability of the scoring tables for different geographical regions and medical staff. That is, it corresponds to the different triage needs of different people in different regions, thus realizing the accurate application of triage in various complex situations.

[0011] According to a preferred embodiment, the said triage provision includes: determining at least one highest-priority unasked question from all selected relevant classification categories; asking the patient at least one highest-priority unasked question; and repeating the above steps for all selected triage categories until the patient's triage allocation is determined.

[0012] According to a preferred embodiment, the control sub-units in several of the said LoRa terminals can be interconnected to form a local area network within the medical institution, respond to the call of medical staff and feedback the current position of the called person according to the local area network information when called, so that medical staff can dispatch medical services to the position of the caller when necessary.

[0013] According to a preferred embodiment, a patient can make a call to medical staff through the LoRa terminal. If the call is not the first call, the call process is continued by determining that the call is a subsequent call, and the subsequent call is a call based on a medical condition previously resolved by the triage system. Medical staff can ask the patient at least one question about their call through the triage system to determine the source or reason for the patient's call and allow the medical staff to select a relevant category.

[0014] According to a preferred embodiment, if it is determined that the call is a subsequent call, the system is set to a subsequent call by accessing data related to the original event, which is associated with the patient's personal data, such that the subsequent call data and the original event data are linked in the database and can help medical staff understand the previous event or situation; if it is determined that the call is not a subsequent call, the call is set as an original call, so as to be able to conduct an initial query on the patient's condition and personal data in order to determine the appropriate care level for the patient.

[0015] According to a preferred embodiment, the system can accurately assign a triage category to a patient based on a number of variables related to the patient. The system can use a model to provide a classification category recommendation based on data of a number of variables obtained for the patient. The model is created, tested, and adjusted according to patient data obtained from patients previously triaged. Therefore, by using the model, a more accurate triage category can be assigned to the patient. In addition, the triage system can be corrected based on data collected in a specific environment, thereby generating a triage system tailored to that specific environment (such as different triage levels existing in a geographical area, etc.).

[0016] According to a preferred embodiment, a search unit for searching for other LoRa terminals within a distance threshold range around the LoRa terminal is provided in the LoRa terminal, and the triage management unit can be electrically connected to the LoRa terminal; wherein, a control subunit for recording the number of other LoRa terminals within the distance threshold range of the LoRa terminal and / or the distances from the LoRa terminal to other LoRa terminals respectively is further provided in the LoRa terminal. In response to a call from a medical staff member, the control subunit establishes temporary communication connections with at least one other LoRa terminal around the LoRa terminal and at least another LoRa terminal within the local area network. Moreover, the control subunit calculates the coordinates of its current temporary location based on the fixed strength of the wireless signals between it and at least two other LoRa terminals and the coordinate information fed back by other LoRa terminals, so that the medical staff can dispatch medical services to the location of the caller when necessary. The LoRa terminal of the present invention can determine its location based on the wireless signals of fixed strength, so that the medical staff can dispatch medical services to the location of the caller when necessary, enabling the current location of the patient to be obtained in a timely manner when the patient encounters an emergency or is unable to respond to the call, and dispatching the medical staff to reach that location for first aid.

[0017] The search unit adopts the prior art. For example, the search unit can adopt Bluetooth technology to identify the distance between two Bluetooth devices (such as the LoRa terminals in the present invention), that is, the search unit of one LoRa terminal simply relies on the received signal strength information (RSSI) emitted by the search unit of other LoRa terminals to determine the distance between two LoRa terminals; meanwhile, using Bluetooth technology to measure the distance between two LoRa terminals can achieve a distance accuracy of up to the meter level.

[0018] According to a preferred embodiment, the triage management unit can further include a display subunit for displaying and reminding people to maintain an appropriate social distance, and the display subunit can be electrically connected to the control subunit of the LoRa terminal; in the case where the triage management unit or the LoRa terminal issues a warning when there are more other LoRa terminals than the quantity threshold within the distance threshold range of a single LoRa terminal, the triage management unit can be electrically connected to the LoRa terminal.

[0019] Through this configuration method, the LoRa terminal can at least record the number of other LoRa terminals within its distance threshold range, and / or the distances from the LoRa terminal to other LoRa terminals respectively; when the number of warning values recorded / statistical by the control subunit reaches or exceeds the alarm threshold, the alarm unit electrically connected to the control subunit starts the alarm operation, so as to remind the user to keep an appropriate social distance from other people carrying the same type of LoRa terminal (for example, the social distance that complies with local epidemic prevention policies). When a single LoRa terminal aggregates more than the number threshold of other LoRa terminals within its distance threshold range, not only can the alarm unit of the LoRa terminal emit an alarm sound to remind the user to keep an appropriate social distance from other people carrying the same type of LoRa terminal, but also it can be displayed in the hospital hall through the display subunit of the triage management unit electrically connected to the control subunit to remind the user again to keep an appropriate social distance from other people carrying the same type of LoRa terminal.

[0020] Advantageous technical effects of the present invention:

[0021] (1) During triage, the present invention incorporates other information of the patient, such as triage date and time, the patient's past medical history, age, etc. into the judgment factors, enters and judges multiple pieces of information of the injured person at the same time, and matches the patient's current state through a scoring table, so as to perform a predetermined score more quickly and conveniently, and thus perform timely and accurate patient triage allocation;

[0022] (2) The present invention also provides the variability of the scoring tables for different geographical regions and medical staff. That is, it corresponds to the different triage needs of different people in different regions, so as to achieve the accurate application of triage in various complex situations;

[0023] (3) The LoRa terminal of the present invention can obtain its own location based on a wireless signal of a fixed intensity, so that medical staff can dispatch medical services to the location of the caller when necessary, enabling the patient's current location to be obtained in a timely manner when the patient encounters an emergency or cannot respond to the call, and dispatching medical staff to reach that location for first aid.

[0028] The present invention will be described in detail below with reference to the accompanying drawings.

[0029] Embodiment 1

[0030] Figure 1 A triage system for emergency department is shown. The triage system for emergency department at least includes a triage management unit 1 and a LoRa terminal 2. One LoRa terminal 2 can only be assigned to one user. A search unit 3 is disposed or integrated in the LoRa terminal 2 for searching other LoRa terminals 2 within a distance threshold range around the LoRa terminal 2. The LoRa terminal 2 is set as a wearable terminal, and the LoRa terminal 2 is integrated in a packaging block, and the packaging block is fixed on the wrist by an adjustable belt; wherein, the LoRa terminal 2 includes a LoRa sub-module, a power sub-module and a prompt sub-module, the prompt sub-module is at least one of a vibration device, a buzzer and an LED lamp and is disposed in the packaging block, and the power sub-module is also disposed in the packaging block and supplies power to the LoRa terminal 2.

[0031] When the triage management unit 1 or the LoRa terminal 2 can issue a warning when there are more than a threshold number of other LoRa terminals 2 within the distance threshold range of a single LoRa terminal 2, the triage management unit 1 can be electrically connected to the LoRa terminal 2 to prevent a single LoRa terminal 2 from aggregating more than a threshold number of other LoRa terminals 2 within its distance threshold range.

[0032] Preferably, the triage management unit 1 can be electrically connected to the LoRa terminal 2 in a wireless connection manner.

[0033] The search unit 3 adopts the existing technology. For example, the search unit 3 can adopt Bluetooth technology to identify the distance between two Bluetooth devices (such as the LoRa terminal 2 in the present invention), that is, the search unit 3 of one LoRa terminal 2 simply relies on the signal strength information (RSSI) sent by the search unit 3 of other LoRa terminals 2 to determine the distance between two LoRa terminals 2; at the same time, using Bluetooth technology to measure the distance between two LoRa terminals 2 can achieve a distance accuracy of the meter level.

[0034] According to a preferred embodiment, a control subunit 201 is further disposed in the LoRa terminal 2, wherein the control subunit 201 is electrically connected to the search unit 3.

[0035] Preferably, the control subunit 201 can set the alarm threshold of the control subunit 201 in a manually set manner, so that when the number of warning values of other LoRa terminals 2 existing within the threshold distance range recorded by the control subunit 201 exceeds the alarm threshold, the alarm unit 202 electrically connected to the control subunit 201 can at least emit an alarm sound.

[0036] The number of warning values is used to represent the number of other personnel using the same type of terminal within the distance threshold range around the terminal used by the user.

[0037] When the distance between a certain terminal searched by the search unit 3 and the present terminal is greater than the distance threshold, the control subunit 201 adds zero to the number of warning values;

[0038] When the distance between a certain terminal searched by the search unit 3 and the present terminal is less than or equal to the distance threshold, the control subunit 201 adds one to the number of warning values; and so on.

[0039] Preferably, the distance threshold can be set according to the actual application requirements. For example, the distance threshold can be set to two meters.

[0040] Preferably, the alarm threshold can also be set according to the actual application requirements. For example, the alarm threshold can be set to two.

[0041] Preferably, the control subunit 201 can adopt existing technologies. For example, the control subunit 201 can adopt a PLC programmable logic controller of existing technologies, and can manually set the alarm threshold, that is, when the control subunit 201 obtains a value that reaches or exceeds the alarm threshold, the alarm unit 202 electrically connected to the control subunit 201 is activated and at least emits an alarm sound. It should be noted that all the technologies adopted in the present invention are existing technologies, which neither involve the improvement of the internal structure of the existing PLC programmable logic controller nor require the protection of the algorithm or software part on how the control subunit 201 obtains the number of other LoRa terminals 2 within the threshold distance range of the current terminal. In short, the control subunit 201 can simply use addition and subtraction methods to count the number of warning values, that is, when the search unit 3 of the LoRa terminal 2A used by the user searches for the distance and / or quantity of all other terminals of the same type within the threshold distance range, and sequentially counts whether the distance between each other terminal of the same type and the present terminal is less than the distance threshold. If the distance between the other terminal of the same type and the present terminal is less than the distance threshold, the control subunit 201 adds one to the counted number of warning values; if the distance between the other terminal of the same type and the present terminal is greater than or equal to the distance threshold, the control subunit 201 adds zero to the counted number of warning values; at the same time, when a certain other terminal of the same type with a distance less than the distance threshold from the present terminal changes to be greater than the distance threshold, the control subunit 201 subtracts one from the counted number of warning values, and so on.

[0042] It should be noted that, to further illustrate that the control subunit 201 of the present invention adopts the prior art, the present invention gives its various specific composition methods. The control subunit 201 can be a multi-bit adder-subtractor composed of multiple full adders; the control subunit 201 can realize addition by combining a decimal encoder and an addition operation circuit, and perform subtraction through the complement of numbers; the control subunit 201 can write the S_CUD addition and subtraction counting of Siemens PLC into the control subunit 201 to perform addition and subtraction.

[0043] Through this configuration method, the control subunit 201 can at least be used to record the number of other LoRa terminals 2 within the distance threshold range of the LoRa terminal 2, and / or the distances from the control subunit 201 to other LoRa terminals 2 respectively; when the number of warning values recorded / statistical by the control subunit 201 reaches or exceeds the alarm threshold, the alarm unit 202 electrically connected to the control subunit 201 starts the alarm operation.

[0044] According to a preferred embodiment, an alarm unit 202 is further provided in the LoRa terminal 2. The control subunit 201 is electrically connected to the alarm unit 202 so that the alarm unit 202 can at least emit an alarm sound when there are more than the number threshold of other similar terminals within the distance threshold range of the LoRa terminal 2.

[0045] The alarm unit 202 can directly adopt the prior art. For example, various models of miniature speakers produced by Ole Wolff, such as OWS-1943T-8CP, etc., can be used.

[0046] According to a preferred embodiment, the triage management unit 1 can further include a display subunit, and the display subunit can be electrically connected to the control subunit 201 of the LoRa terminal 2.

[0047] The display subunit can directly adopt the prior art. For example, a liquid crystal splicing screen, that is, LCD display technology, can be used. Specifically, the display subunit can adopt a liquid crystal splicing screen of model YT-46V1 produced by whynotinfo.

[0048] Through this configuration method, when a single LoRa terminal 2 aggregates more than the number threshold of other LoRa terminals 2 within its distance threshold range, not only can the alarm unit 202 of the LoRa terminal 2 emit an alarm sound to remind the user to maintain an appropriate social distance from other personnel carrying similar LoRa terminals 2, but also it can be displayed in the hospital hall through the display subunit of the triage management unit 1 electrically connected to the control subunit 201 to remind the user again to maintain an appropriate social distance from other personnel carrying similar LoRa terminals 2.

[0049] According to a preferred embodiment, the triage management unit 1 includes a triage management subunit and a LoRa gateway, and the triage management subunit and the LoRa gateway are electrically connected. Among them, the triage management unit 1 is electrically connected to the LoRa terminal 2 through the LoRa gateway.

[0050] According to a preferred embodiment, it further includes a server, a main switch, a floor switch signal-connected to the main switch, a triage management unit 1 connected to the floor switch, and a medical treatment device unit. The medical treatment device unit includes a call bell. Among them, the triage management unit 1 is disposed within the triage management unit 1.

[0051] According to a preferred embodiment, the LoRa terminal 2 further includes a LoRa sub-module, a power supply sub-module, and a prompting sub-module. Among them, the LoRa sub-module, the power supply sub-module, and the prompting sub-module can be electrically connected to the control subunit 201 respectively.

[0052] According to a preferred embodiment, the LoRa terminal 2 is a wearable terminal, and the prompting sub-module is at least one of a vibration device, a buzzer, and an LED lamp.

[0053] According to a preferred embodiment, the power supply sub-module includes a storage battery, a charging circuit, and a charging interface connected in sequence. Among them, the storage battery can be electrically connected to at least the searching unit 3, and the charging interface and the charging circuit are electrically connected to the storage battery in sequence.

[0054] According to a preferred embodiment, the floor switch is electrically connected to the main switch, and the floor switch and the main switch are disposed on each floor. The floor switch on each floor is electrically connected to the triage management unit 1 and the medical treatment device unit on that floor.

[0055] This emergency triage system can further include: a server, a main switch, a floor switch signal-connected to the main switch, a triage management unit 1 connected to the floor switch, and a medical treatment device unit.

[0056] The medical treatment device unit includes a call bell.

[0057] The triage management unit 1 includes a management device and a LoRa gateway connected to the management device, and further includes a LoRa terminal 2.

[0058] The LoRa terminal 2 includes a control subunit 201, a LoRa sub-module, a power supply sub-module, and a prompting sub-module all connected to the control subunit 201.

[0059] The LoRa terminal 2 is a wearable terminal.

[0060] The LoRa terminal 2 includes a bracelet.

[0061] The prompt sub-module is at least one of a vibration device, a buzzer, and an LED lamp.

[0062] The power supply sub-module includes a storage battery, a charging circuit, and a charging interface that are connected in sequence.

[0063] An electrostatic discharge circuit is connected to the power output terminal of the power supply sub-module.

[0064] The electrostatic discharge circuit includes a transient voltage suppression diode TVS with an anode grounded.

[0065] The LoRa terminal 2 is a mobile terminal to realize patient visit reminder. The floor switch is signal-connected to the main switch and is placed on each floor.

[0066] The floor switch on each floor is connected to the triage management unit 1 and the visit device unit on that floor. Its hardware selection and connection relationship can be realized by using the existing structure.

[0067] The visit device unit includes a call bell; the triage management unit 1 includes a management device and a LoRa gateway connected to the management device; the LoRa terminal 2 includes a control sub-unit 201, a LoRa sub-module, a power supply sub-module, and a prompt sub-module, and the LoRa sub-module, the power supply sub-module, and the prompt sub-module are all connected to the control sub-unit 201.

[0068] When a patient registers for a visit, a LoRa terminal 2 is allocated. The management device realizes the binding of the LoRa terminal 2 with the patient's identity information; when calling a number, the doctor calls the patient through the call bell. After the management device receives the call information, it sends information to the corresponding LoRa terminal 2 through the LoRa gateway. After the LoRa terminal 2 receives the information, the prompt sub-module acts, and the patient can arrive at the consulting room in advance.

[0069] Specifically, the LoRa terminal 2 control sub-unit 201 can adopt a processor of the STM32F103RBT6 model. The LoRa sub-module, the power supply sub-module, and the prompt sub-module can all be realized by using conventional hardware on the existing market and their conventional connections, which will not be elaborated here.

[0070] Through the above modules and their connection structures, a hardware basis can be provided for realizing the above-mentioned contactless automatic triage of patients.

[0071] To facilitate the patient to carry the LoRa terminal 2 with them and avoid loss, the LoRa terminal 2 is a wearable terminal.

[0072] Specifically, a bracelet structure or a pendant structure can be adopted. Preferably, a bracelet structure is adopted, that is, the LoRa terminal 2 is integrated in a packaging block, and the packaging block is fixed on the wrist by an adjustable belt.

[0073] The prompting sub-module is at least one of a vibration device, a buzzer, and an LED lamp. Preferably, a vibration device is adopted. Specifically, the vibration device can adopt an eccentric wheel vibrator motor, such as the N 15 vibration motor of XINLIMOTOR. The buzzer can adopt the TMB 12A05 of Huanneng. When the bracelet is combined with the vibration device, it can avoid disturbing others during the waiting for medical treatment in the leisure places outside the hospital. Compared with the LED lamp, its prompting effect is also very good.

[0074] The power supply sub-module includes a storage battery, a charging circuit, and a charging interface connected in sequence. The storage battery of the power supply sub-module is charged by the charging circuit, enabling the LoRa terminal 2 to be used in a cycle.

[0075] Since the LoRa terminal 2 is wearable, in the dry seasons of autumn and winter, the human body is extremely prone to generating static electricity. When the static electricity acts on the LoRa terminal 2, it will cause great damage to its circuit structure. In order to discharge the static electricity and protect the circuit inside the LoRa terminal 2, a static electricity discharge circuit is connected to the power output end of the power supply sub-module. Specifically, the static electricity discharge circuit includes a transient voltage suppression diode TVS with the anode grounded, that is, the cathode of the transient voltage suppression diode TVS is connected to the power output end and the power supply port of the control sub-unit 201.

[0076] Embodiment 2

[0077] This embodiment is a further supplement to the above embodiment, and the repeated parts will not be elaborated.

[0078] Before describing the specific embodiments, the hardware structure in the embodiments will be described first.

[0079] Server: Any type of computer or processing system, including but not limited to mobile terminals, personal computers (PCs), personal digital assistants (PDAs), mainframe computers, network devices, systems with databases capable of storing and processing patient information, or other devices or combinations of devices. It is widely defined to cover any device or combination of devices having at least one processor that executes instructions from a storage medium.

[0080] In fact, in the field of emergency departments, usually a catastrophic danger occurs, resulting in multiple injured people. Now, they are often triaged according to the severity of the injuries to prioritize the patients. However, the severity of the injured is affected by many factors. During triage, other information of the patients, such as the triage date and time, the patient's past medical history, age, etc., all need to be included in the judgment factors. Especially for a large number of injured people caused by large-scale disasters (such as car accidents, earthquakes, etc.), medical institutions cannot timely input and judge multiple information of the injured people simultaneously. Based on the above problems, the present invention provides an emergency department triage system.

[0081] According to a preferred embodiment, the emergency triage system of the present invention determines the urgency for a patient to receive treatment or outpatient service based on the severity of the patient's condition, and assigns a relative priority to each patient through various medical factors such as symptoms. Preferably, at least one database for storing data provided by the patient and / or data derived from the patient can be integrated in the server, including patient population statistics, factors related to priority assessment, dispositions, subsequent classifications, or other data from the patient. The above-mentioned derived data is the pre-scored data for the patient for at least one medically predetermined characteristic. For example, the scored data can be evaluated based on at least one scoring form. For quantitative or qualitative medical conditions, at least one evaluation score can be assigned according to the severity of the condition. The derived data can be used in combination with the scoring form to receive queries from the server and provide appropriate responses. For example, a given amount of pain, shortness of breath, or degree of burn can be matched with the patient's current state according to the scoring form to perform the predetermined scoring more quickly and conveniently.

[0082] As described above, it is difficult to perform accurate triage on patients. In most cases, for example, when emergency responders or medical staff evaluate and / or transport patients, triage (such as triage of trauma categories) needs to be carried out promptly and accurately. In this case, the present invention performs triage on patients by using at least one scoring form for priority selection. The scoring form designates at least one medically predetermined characteristic (such as vital signs, location or type of trauma, etc.). According to this scoring form and at least one standard value related to the patient, the patient is assigned. The key point of the present invention also lies in providing the variability of the scoring forms for different geographical regions and medical staff. That is, it corresponds to the different triage needs of different regions and different personnel, thus realizing the accurate application of triage in various complex situations. It should be noted that the scoring form can also be defined using only a few criteria. For example, due to various uncontrollable factors, such as the complexity of determining the standard value, the applicability of such scoring forms, time issues, etc. Therefore, the classification category assignment of the scoring form reaches a degree that can be clearly distinguished. For example, in most cases, the scoring form is set to two types, one for assigning triage levels to adults and the other for assigning triage levels to children. In addition, triage of trauma categories can be mainly assigned according to three fields: physiology, cause of injury, and site of injury. The above fields can be assigned when performing a preliminary physical examination on the patient in a medical institution. In some cases, these three fields may not be sufficient for accurate category assignment.

[0083] According to a preferred embodiment, a number of scoring tables assign the severity of a patient's medical condition to a number of assessment scores. Based on the assessment scores, the first priority of patient triage is determined. The server generates at least one medical institution scoring table based on different geographical regions and / or processing capabilities of the medical institution to analyze the second priority and calibrate the first priority according to the second priority. The first priority is selected based on the patient's physiological signs and past medical history. For example, those with an assessment score at level one (i.e., unstable vital signs requiring immediate first aid) include: cardiac and respiratory arrest, severe chest pain, persistent severe arrhythmia, severe dyspnea, severe traumatic hemorrhage, acute poisoning, and combined injuries in the elderly, etc. Those with an assessment score at level two (i.e., having potential life-threatening and the condition may change rapidly) include cardiovascular and cerebrovascular accidents; severe fractures, sudden severe headache, abdominal pain lasting more than 36 hours, open trauma, high fever in children, etc. Those with an assessment score at level three (i.e., vital signs are still stable and acute symptoms cannot be relieved continuously) include high fever, vomiting, minor trauma, mild abdominal pain, etc. The above gives a rough assessment score. A more specific assessment score can be expressed in the form of formulas, curves, relation tables, etc., to be precise to each symptom. In this embodiment, only a simple description is given. The first priority is also calibrated by the second priority. Since the first priority only considers the triage needs under normal medical treatment and does not consider the priority improvement in large-scale disasters or emergencies, the second priority is introduced to calibrate the first priority. For example, in the event of a large-scale earthquake or flood, since a large number of patients with the same symptoms are sent to medical institutions, they need to be further divided according to the specific symptoms caused by the disaster. For example, in the event of an earthquake, most patients have severe traumatic hemorrhage. The second priority further divides them, thus forming a calibration of the first priority. The division includes the affected area, bleeding volume, etc. The second priority also calibrates the first priority based on the social conditions in different regions. For example, in the event of an infectious disease (such as an epidemic), the first priority classifies fever as an assessment score at level three. However, due to the current regional needs, the assessment score of fever is increased, and a special warning is issued to prioritize the treatment of such symptoms. The second priority increases the weight of fever in the first priority to achieve real-time supervision of the patients that need to be prioritized for treatment in medical institutions. The second priority also calibrates the first priority based on the processing capabilities of medical institutions. As mentioned above, in the event of an earthquake, a large number of patients with the same symptoms are sent to medical institutions. Due to the limited processing capabilities of medical institutions, it may not be possible to triage and allocate all patients at the best time. In this regard, the second priority calibrates the first priority, taking the required treatment time and the waiting time that can be tolerated as the focus criteria of the first priority, and diverting the patients with a long waiting time that can be tolerated, such as transferring to another hospital for treatment, etc. The calibration of the first priority can avoid delaying the patient's condition and enable the patient to receive timely treatment.The present invention obtains a second priority based on the different geographical regions and / or processing capabilities of medical institutions, and calibrates the first priority with this, so as to more accurately determine the triage allocation of patients. Compared with the prior art that simply triages patients based on their symptoms, the multiple factors considered in the present invention can more accurately reflect the priority of triage required by patients.

[0084] According to a preferred embodiment, the server updates at least one medical institution score table in a real-time iterative manner and analyzes the second priority. The advantage of real-time iteration is that real-time updating of the medical institution score table can prevent delays in the best treatment time for patients and reasonably allocate the patient flow, making the triage allocation more accurate. The real-time iteration of the second priority also lies in introducing the symptom occurrence frequency as a calibration standard for the first priority. For example, among the symptoms rated as level three, if they occur three or more times within half an hour, the second priority should increase the first priority. If they occur only once or twice within half an hour, the patient's condition is non-urgent, and the second priority does not need to calibrate the first priority. Such a setting can reduce the amount of data processing and make corresponding adjustments according to the real-time changes of the patient's symptoms, thereby saving triage time and waiting time. It should be noted that the above frequency setting is only exemplary, and those skilled in the art can further divide it based on formulas, curves, relationship tables, etc. After calibrating the first priority according to the second priority, the LoRa terminal 2 can be called and reminded by medical staff and the real-time position of the LoRa terminal 2 can be located, so as to allocate patients according to the real-time changes of the triage situation.

[0085] The implementation scheme of the emergency triage system of the present invention can be adopted in a variety of complex medical treatments to more accurately assign triage categories to patients based on multiple variables related to the patients. The emergency triage system can adopt a model to provide classification category suggestions based on data of multiple variables obtained for the patients. In one embodiment, the model is created, tested, and adjusted according to patient data obtained from previously triaged patients. Therefore, by using this model, more accurate triage categories can be assigned to patients. In addition, the triage system can be corrected based on the data collected in a specific environment, thereby generating a triage system tailored to this specific environment (such as different triage levels existing in a geographical region, etc.). The above patient data can include the triage category assigned to the patient in the medical institution, the determined vital signs in the medical institution, patient demographics, cause of injury, intervention measures, patient management characteristics, injury site, disposition (such as the accuracy of the pre-triage level assigned in the medical institution, which is determined based on the patient treatment outcome), the triage level assigned to the patient, bleeding status, pulse characteristics, or other characteristics. As understood by those skilled in the art, there are numerous characteristics for collecting patient data (such as at a higher order of magnitude).

[0086] According to a preferred embodiment, a LoRa terminal 2 is allocated during medical registration, and the management device realizes the binding of the LoRa terminal 2 with the patient identity information. The triage management unit 1 is configured in multiple medical institutions and can comprehensively record medical institution data including the processing capacity, geographical location, and current building conditions of the above-mentioned medical institutions. The server can be connected to a number of LoRa terminals 2 and triage management units 1. The server is further configured to: after scoring the patient's medical condition and sending the medical condition to the server, list the corresponding medical institutions and / or doctors for the patient through establishing a triage model; the patient selects the medical institutions and / or doctors through the triage model, and the server generates a guiding route from the patient's current coordinates to the selected medical institutions and / or doctors based on this selection and in combination with the triage map; wherein the server accesses the publicly available map database and generates at least two guiding routes from the patient's current coordinates to the selected medical institutions and / or doctors; the server accesses the triage map, obtains the distribution of warning areas on the guiding route, and further selects the generated guiding route by avoiding the range where the warning areas are located. The above-mentioned warning areas refer to areas where there is overcrowding and / or an infection risk due to excessive pedestrian flow. Specifically, the server obtains the patient's current coordinates and orientation by accessing the coordinates of the LoRa terminal 2, and guides the patient to the medical institution and / or doctor based on the patient's current coordinates and orientation in combination with the publicly available map database. Preferably, the route from the medical institution to the corresponding doctor within the medical institution is generated with a corresponding guiding perspective by the server. Preferably, the server generates the guiding perspective in the following manner. The server takes the medical institution where the patient arrives as the starting point and the direction of entering the medical institution as the patient's orientation, and at the same time retrieves the data of each floor and the floor height data associated with the corresponding doctor and the starting point coordinates of the corresponding patient to complete the perspective modeling. Preferably, the server can generate a simulated portrait identical to the patient's starting point and orientation when performing perspective modeling. After the patient arrives at the medical institution according to the guiding route, the patient starts to be guided by the perspective. The patient's starting point and orientation match the corresponding guiding perspective, and the patient can move in the guiding perspective based on the simulated portrait corresponding to their own coordinates and orientation, and determine the reference points on the guiding route by adjusting the perspective of the corresponding simulated portrait. When moving within the medical institution, the patient can view the guiding perspective through the LoRa terminal 2, and can observe the guiding perspective from multiple angles by adjusting the orientation of the simulated portrait, so as to compare the feature points in the guiding perspective with the actual feature points to determine the guiding route and thus achieve the purpose of reaching the corresponding doctor. During the process of guiding the patient through the LoRa terminal 2, the LoRa terminal 2 can only receive the image data of the guiding perspective generated by the server, rather than the specific parameters of the medical institution.The generation of the guiding perspective is all produced in the server and is not affected by the LoRa terminal 2, thus avoiding the caching of data in the medical institution in the LoRa terminal 2 due to the perspective modeling performed by the LoRa terminal 2 worn by the patient, and further reducing the risk of leakage of specific parameters of the medical institution. The orientation of the patient can also be obtained from the gyroscope built into the LoRa terminal 2 when the patient raises the arm to view the LoRa terminal 2.

[0087] According to a preferred embodiment, a data screening module for obtaining data including the medical condition of the patient and / or the medical field of the doctor and / or the evaluation of the doctor's diagnosis of the corresponding medical condition in this field and / or the official ranking of the medical institution in this field and / or the distance between the medical institution and the patient is also provided in the server. The data screening module is further configured to: when determining the medical condition of the patient, overall plan the doctors who can diagnose this medical condition, obtain the distance between the medical institution to which each doctor belongs and the current coordinates of the patient, set at least one preset threshold to determine whether this distance is greater than the threshold, so as to select the medical institutions and / or doctors with a distance less than the threshold. The specific steps include:

[0088] S1: Select the doctors who can diagnose the medical condition of the patient and the medical institutions to which these doctors belong from the doctor database according to the medical condition of the patient;

[0089] Before this step is executed, it is necessary to determine the medical condition of the patient, which can be obtained through the above-mentioned scoring, and then select the doctors who can diagnose this medical condition according to the scoring;

[0090] S2: Obtain the evaluation of the doctor's diagnosis of the corresponding medical condition in this field from the doctor database, and determine the medical weight of this doctor according to this evaluation;

[0091] S3: Obtain the official ranking of the medical institution to which this doctor belongs from the doctor database, and determine the medical institution weight of this doctor according to this ranking;

[0092] S4: Obtain the distance between the medical institution to which this doctor belongs and the current coordinates of the patient from the doctor database, and determine the distance weight of this doctor according to the distance;

[0093] S5: Establish a triage model according to the medical weight, medical institution weight and distance weight of this doctor. This triage model determines the medical index of this doctor for the patient to whom he belongs, and sorts the corresponding doctors through the medical index so that the patient can make a self-selection;

[0094] Preferably, the above-mentioned several doctors can be summarized into a medical list belonging to this patient, and the patient makes a self-selection in the form of a list.

[0095] The medical index is specifically as follows: The medical index of the triage model is obtained by multiplying the medical weight, the medical institution weight, and the distance weight. The corresponding doctors are sorted in a list according to the arrangement of the values of the medical index and provided to the patients. It should be noted that the triage system of the present application can achieve overall triage of all medical institutions in the area, rather than being limited to the triage of the current medical institution only.

[0096] Embodiment 3

[0097] This embodiment is a further supplement to the above embodiment, and the repeated parts will not be described again.

[0098] According to a preferred embodiment, the control sub-units 201 in several LoRa terminals 2 can be connected to each other to form a local area network within the medical institution, respond to the call of medical staff, and feedback the current position of the called person according to the local area network information during the call, so that medical staff can dispatch medical services to the position of the caller when necessary. Specifically, the control sub-unit 201 responds to the call of medical staff, establishes a temporary communication connection with at least one other LoRa terminal 2 around the LoRa terminal 2 and at least one other LoRa terminal 2 within the local area network, and the control sub-unit 201 calculates the coordinates of its own current temporary position according to the fixed strength of the wireless signal between it and at least two other LoRa terminals 2 and the coordinate information fed back by the other LoRa terminals 2, so that medical staff can dispatch medical services to the position of the caller when necessary. The control sub-unit 201 can emit a wireless signal with a fixed strength containing position information. The position information includes the current floor and the coordinate point within the floor. The LoRa terminal 2 receives the wireless signal containing position information, and calculates its own coordinates according to the distance from other LoRa terminals 2 (calculated by the fixed strength) and the coordinate points of other LoRa terminals 2. Preferably, the LoRa terminal 2 can also obtain its own current position coordinates according to the wireless signal with a fixed strength emitted by the floor switch on each floor.

[0099] Patients can also call medical staff through the LoRa terminal 2. If the call is not the first call, the process is continued by determining that the call is a subsequent call. A subsequent call is a call based on a medical condition previously resolved by the triage system.

[0100] If it is a subsequent call, the system is set to a subsequent call by accessing the data related to the original event. These data can be associated with the patient's personal data, so that the subsequent call data and the original event data are linked in the database, and can help medical staff understand the previous events or situations.

[0101] If it is not a subsequent call, the call is set as the original call, enabling an initial inquiry into the patient's condition and personal data. The patient's age can be collected to determine the appropriate level of care for the patient. For example, chest pain in a 75-year-old patient may indicate a heart attack, while chest pain in a 16-year-old patient may not be a heart attack. If the patient is identified as a minor, the "Minor Pre-Triage" framework can be enabled, providing options to select a type of legal consent. Before the call proceeds, legal consent criteria can be required to prevent unauthorized minor triage.

[0102] According to a preferred embodiment, the triage system can set a number of relevant triage categories. Each of these triage categories is grouped into a number of hierarchical selections based on the patient's body part and / or type of injury, with each said hierarchical selection corresponding to one of the triage categories; based on the severity of the patient's medical condition, at least one first patient triage category and a second patient triage category are provided for selection from a number of triage categories; triage classification questions and relevant information for the selected patient classification category are provided and triage is provided to the patient. Providing triage includes: determining at least one highest-priority unasked question from all selected relevant classification categories; asking the patient at least one highest-priority unasked question; and repeating the above steps for all selected triage categories until the patient's triage assignment is determined. Specifically, the classification category can correspond to the patient's body part and / or type of injury to be the focus of the triage assignment. The category can generally be based on the patient's symptoms. Each category contains triage classification questions and relevant information. Categories related to specific body parts can include "abdominal injury", "abdominal pain without injury", "chest pain without injury", "chest injury", "tooth injury", "upper limb pain without injury", "upper limb pain without injury", "lower limb pain without injury", etc. Triage categories not necessarily related to a specific body part can include "bite", "bloodborne pathogen exposure", "burn", "electric shock", "frostbite", "insect bite", etc. Medical staff can ask the patient at least one question about the severity of their medical condition through the triage system to determine the source or cause of the patient's call and enable the medical staff to select relevant categories. For example, if the patient states that he fell from a ladder, resulting in a head injury and a cut arm for the patient, then the medical staff can select the "head injury" and "laceration" categories. The supporting information and hierarchical triage questions in these two categories can be set by the medical staff, such as lacerations and craniocerebral injuries. If multiple relevant classification categories are selected, these categories can be prioritized. The priority is determined according to the description provided by the triage system or by the rules of the medical staff. For example, such a rule can provide that the "chest pain" category always has a higher priority than the "groin strain" category.

[0103] Both category selection and body part selection can be completed in the triage management unit 1. The selection of the first patient triage category and the second patient triage category means that the same category is applied multiple times to different parts of the body by re-selecting the same category while selecting different body parts. For example, the laceration category can be applied to both the hand and the elbow simultaneously as the primary and secondary body parts. Different categories can also be applied to the same body part, for example, if there is both a burn and an open wound in the same place. When all or part of the categories and body parts are selected, medical staff determine the priority of the selection.
