Description

A patient monitoring device that easily links vital sign data and an electronic medical record system including the same.

[0001] The present invention relates to a patient monitoring device and an electronic medical record system including the same, and more particularly, to a patient monitoring device that conveniently links vital sign data and an electronic medical record system including the same.

[0002] Vital signs are indicators of a person's state of life and are crucial measurements for assessing health. Examples include body temperature, blood pressure, pulse rate, and respiration rate. In hospital operating rooms, examination rooms, and treatment rooms, healthcare professionals, such as doctors and nurses, monitor patients' vital signs using patient monitors.

[0003] However, conventional patient monitoring devices have many problems in the process of monitoring and recording the patient's vital signs.

[0004] For example, in many wards, healthcare workers currently carry patient monitors and laptops on carts, measuring patients' vital signs using the monitors and then entering the data into the laptops on the carts. This method presents a constant risk of data entry errors and inconvenience. This situation is particularly dire in cramped emergency rooms and wards, where cart access is difficult. Healthcare workers carry monitors around, measure multiple patients' vital signs, manually record the data on paper, and then later re-enter the data into a terminal connected to the EMR server. This manual data entry method is prone to errors and can lead to errors and missing patient information. This not only hinders the accuracy of medical records, but can also compromise patient safety.

[0005] One could explore ways to wirelessly connect patient monitoring devices to EMR servers, but most hospitals are sensitive to patient privacy and confidentiality in accordance with the Personal Information Protection Act, making it realistically very difficult to wirelessly connect patient monitoring devices directly to EMR servers due to hospital security policies.

[0006] The problem that the present invention seeks to solve is to provide a patient monitoring device that can not only protect patient personal information but also easily link vital sign data to an EMR server.

[0007] Another problem that the present invention seeks to solve is to provide an electronic medical record system including such a patient monitoring device.

[0008] The problems to be solved by the present invention are not limited to the problems mentioned above, and other problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.

[0009] According to one embodiment of the present invention for achieving the above object, a patient monitoring device is a device for measuring vital sign data of a patient, comprising: a scanner for recognizing personal identification information of the patient by scanning a barcode attached to the patient's wrist; a sensor attached to the patient for measuring vital sign data; a first display for displaying the vital sign data measured from the sensor in real time; a controller for generating a QR code by combining the vital sign data measured at a predetermined point in time in response to a first execution event with the personal identification information; and a second display for displaying the QR code in response to a second execution event.

[0010] The QR code may be generated by combining vital sign data, including the patient's electrocardiogram signal, blood pressure signal, body temperature signal, respiration signal, blood oxygen concentration signal, carbon dioxide concentration signal, heart rate signal, or a combination thereof, with personal identification information, including the patient's name, date of birth, ID, or a combination thereof.

[0011] The controller can sequentially generate and store QR codes corresponding to each patient for a plurality of patients, and sequentially display the plurality of QR codes on the second display in response to the second execution event.

[0012] According to an embodiment of the present invention for achieving the above-described other object, an electronic medical record system comprises: an EMR server for managing electronic medical records; a patient monitoring device of claim 1 for recognizing a patient's personal identification information and measuring vital sign data for the patient; and a station terminal connected to the EMR server for inputting the patient's vital sign data. Here, the patient monitoring device combines the vital sign data with the personal identification information to generate a QR code, which is then displayed on a second display. In a state where the communication connection between the station terminal and the patient monitoring device is disconnected, the station terminal reads the QR code displayed on the second display through a QR reader, and then updates the electronic medical record.

[0013] The above patient monitoring device can sequentially generate and store QR codes corresponding to each patient for multiple patients, and sequentially display multiple QR codes on the second display in response to a second execution event.

[0014] Specific details of other embodiments are included in the specific contents and drawings.

[0015] As described above, according to the patient monitoring device of the present invention, a QR code is automatically generated by combining the patient's personal identification information recognized by the scanner and the patient's vital signs data measured by the sensor. While the patient monitoring device displays the QR code on the second display, a station terminal connected to the EMR server reads the QR code using a QR reader, thereby automatically updating the electronic medical record stored in the EMR server.

[0016] In this way, because the patient monitor's scanner automatically recognizes the patient's personal identification information, entry errors can be prevented. Furthermore, vital sign data measured by the patient monitor's sensors are combined with the patient's personal identification information and converted into a QR code. Scanning the QR code automatically updates the electronic medical record, preventing data errors or omissions due to input errors. Furthermore, because vital sign data is transmitted via QR codes while the patient monitor is disconnected from the EMR server or connected station terminals, the patient's personal information or confidential information is prevented from being leaked externally through the patient monitor.

[0020] The advantages and features of the present invention, and the methods for achieving them, will become clearer with reference to the embodiments described in detail below together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms. These embodiments are provided only to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. Like reference numerals designate like elements throughout the specification.

[0021]

[0022] Hereinafter, a patient monitoring device and an electronic medical record system including the same according to one embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2. FIG. 1 is a perspective view schematically showing a patient monitoring device according to one embodiment of the present invention. FIG. 2 is a configuration diagram showing an electronic medical record system according to one embodiment of the present invention.

[0023] The patient monitoring device (10) of the present invention includes a scanner (20), a sensor (45), a first display (30), a second display (35), and a controller (40) that controls them.

[0024] The scanner (20) scans a barcode (25) attached to the patient's wrist to recognize the patient's personal identification information and store it in internal memory. For example, the personal identification information may consist of the patient's name, date of birth, ID, or a combination thereof.

[0025] The sensor (45) is attached to the patient and measures the patient's vital signs data and stores them in internal memory. For example, the vital signs data may consist of the patient's electrocardiogram signal, blood pressure signal, body temperature signal, respiration signal, blood oxygen concentration signal, carbon dioxide concentration signal, heart rate signal, or a combination thereof.

[0026] The first display (30) displays vital sign data measured from the sensor (45) in real time.

[0027] When a user operates the input device of the patient monitoring device (10) and a first execution event occurs, the controller (40) combines vital sign data measured by the sensor (45) at a predetermined point in time in response to the first execution event with personal identification information stored in the internal memory to generate a QR code.

[0028] When a second execution event occurs by the user operating the input device of the patient monitoring device (10), the second display (35) displays a QR code stored in the internal memory in response to the second execution event.

[0029] The controller (40) can sequentially generate and store QR codes corresponding to each of a plurality of patients. For example, when personal identification information of a first patient is input from the scanner (20), the controller (40) matches the vital sign data input from the sensor (45) with the personal identification information of the first patient and stores it. Specifically, when a first execution event occurs by a user operation, the controller (40) combines the personal identification information of the first patient with the vital sign data measured at a predetermined point in time (preferably, the point in time when the first execution event occurs) to generate and store a QR code corresponding to the first patient. If an additional first execution event occurs, the controller (40) updates the QR code corresponding to the first patient by combining the vital sign data measured at the additional point in time when the first execution event occurs with the personal identification information. When a predetermined termination condition is satisfied, the controller (40) ends monitoring of the first patient. For example, the termination condition may be when a predetermined time has passed since personal identification information was entered, when a predetermined time has passed since a QR code was generated, when a termination event occurs due to user input, or when new personal identification information is entered from the scanner (20). After monitoring of the first patient is terminated, the controller (40) matches the vital sign data input from the sensor (45) to the personal identification information of the second patient and stores it. The subsequent process is substantially the same as the process of generating a QR code for the first patient.

[0030] In this way, with QR codes for multiple patients stored, when a second execution event occurs, the controller (40) sequentially displays multiple QR codes on the second display (35) in response to the second execution event. The multiple QR codes may be sequentially displayed at predetermined time intervals. Alternatively, the multiple QR codes may be sequentially displayed when the next event occurs according to a user operation.

[0031] In this embodiment, the first display (30) and the second display (35) are described as being distinct, but the present invention is not limited thereto, and it can be understood that the first display (30) and the second display (35) are not physically distinct but are functionally distinct. For example, one display may display vital sign data in real time (corresponding to the 'first display'), and when a second execution event occurs, the same display may display a QR code (corresponding to the 'second display').

[0032]

[0033] The electronic medical record system (100) of the present invention includes an EMR server (50), a patient monitoring device (10), and a station terminal (55).

[0034] The EMR server (50) electronically stores and manages medical records or medical records for multiple patients. As previously described, the patient monitoring device (10) recognizes the patient's personal identification information and measures vital sign data for the patient.

[0035] The station terminal (55) is connected to the EMR server to input the patient's vital sign data. The station terminal (55) reads the vital sign data in print from the patient monitoring device (10) through the following process while the communication connection with the patient monitoring device (10) is disconnected.

[0036] First, the patient monitoring device (10) combines vital sign data with personal identification information to generate a QR code, which is then displayed on the second display (35). While the communication connection between the station terminal (55) and the patient monitoring device (10) is disconnected, the station terminal (55) reads the QR code displayed on the second display (35) using a QR reader. The station terminal (55) decodes the personal identification information and vital sign data of each patient stored in the QR code and updates the electronic medical record stored in the EMR server (50).

[0037]

[0038] Hereinafter, with reference to FIG. 3, a method for linking vital sign data and electronic medical records according to one embodiment of the present invention will be described. FIG. 3 is a flowchart sequentially illustrating a method for linking vital sign data and electronic medical records according to one embodiment of the present invention.

[0039] First, the patient monitoring device (10) scans the barcode (25) attached to the patient's wrist to recognize the patient's personal identification information and stores it in the internal memory (S10).

[0040] The patient monitoring device (10) measures the patient's vital sign data through a sensor (45) attached to the patient (S12).

[0041] The patient monitoring device (10) generates a QR code by combining vital sign data measured at a predetermined point in time with the patient's personal identification information in response to the first execution event (S14). The patient monitoring device (10) displays the generated QR code on the second display (35).

[0042] The station terminal (55) reads the QR code displayed on the second display (35) through a QR reader (S16).

[0043] The station terminal (55) decodes each patient's personal identification information and vital sign data stored in the QR code and updates the electronic medical record stored in the EMR server (50) (S18).

[0044]

[0045] The aforementioned systems, servers, controllers, modules, etc. may be configured as computer programs, for example, by one or more program modules stored or loaded onto a computer-readable storage medium and implemented by one or more processors. In addition, each step mentioned in the flowchart may be implemented as a computer program, a program module, or a computer-executable instruction.

[0046] Although the embodiments of the present invention have been described with reference to the attached drawings, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without altering the technical concept or essential features thereof. Therefore, the embodiments described above should be understood to be illustrative in all respects and not restrictive.
