Delivery care practice system and method using virtual reality}

The present invention relates to a delivery nursing practice system and method using virtual reality.

The previously developed childbirth simulation practical education for nursing students was an offline practice using a mannequin, and could only provide partial and one-time scenarios related to childbirth in a limited space of the practice room. Additionally, existing childbirth simulators cannot show the process of a fetus coming out of the mother's womb, and only the scene of the fetus coming out through the birth canal can be implemented piecemeal by the instructor. In addition, the existing childbirth simulator only allowed learners to have passive hands-on experience according to the scenario configuration according to the instructor's operation.

Recently, with the development of information and communication technologies, especially realistic technologies such as virtual reality and augmented reality, the use of virtual reality content in games, education and training, and medical fields is increasing.

In particular, research results show that education using realistic technology increases students' immersion and understanding, and in particular, research results show that memory through virtual reality is higher than without it.

The present invention was created in consideration of the above situation, and the technical problem of the present invention is to provide virtual reality that can supplement the learning experience that may be lacking in actual clinical practice by experiencing delivery room practice using virtual reality technology. The goal is to provide a delivery nursing practice system and method using this method.

The delivery nursing practice system using virtual reality according to the present invention to solve the above-described technical problem is a computing device that executes a delivery nursing practice program using virtual reality, and delivery nursing practice according to a delivery nursing practice program executed on the computing device. It includes a display device that displays a virtual reality image for, and a user input device that receives user interaction for delivery and nursing practice from the learner.

The computing device provides delivery and nursing care by allowing learners to interact with virtual objects including virtual patients, virtual doctors, virtual nurses, virtual babies, delivery sets, electronic maternal monitors, electronic fetal monitors, and thermometers in a delivery room or recovery room implemented in virtual reality. Virtual reality content for practicing is provided to the display device.

The computing device creates an unexpected situation that may occur during the delivery process, gives the learner a mission to check the problem, and allows the learner to check the problem through the electronic bulletin board of the virtual delivery room and select the correct answer from the given options. .

The computing device creates an unexpected situation that may occur during the delivery process, assigns a mission that the learner must take to the virtual patient, receives user interaction corresponding to the given mission from the learner, and controls the virtual patient according to the input user interaction. The state can be changed.

According to the present invention, it is possible to configure and implement various scenarios for students beyond the constraints of time and space, allowing students to experience all processes before, during, and after childbirth at once. In addition, the virtual childbirth scenario can be implemented repeatedly alone without an instructor, thereby enhancing the learner's learning effect. Additionally, by showing three-dimensionally how a fetus comes out of the mother's womb and through the birth canal during the birth process, it can stimulate students' interest and improve their understanding of the delivery mechanism. In addition, it has the advantage of strengthening the motivation of learners to engage in practice more actively by providing unexpected situations during learning and providing feedback in a way that allows learners to take the lead in solving problems that occur with patients. .

Referring to FIG. 1, the childbirth nursing practice system using virtual reality according to the present invention may include a computing device 100, a display device 200, and a user input device 300.

The computing device 100 may be implemented as various devices that can perform computational processing and provide results to a user. For example, the computing device 100 may be implemented as a desktop PC, a notebook computer, a server computer, etc.

The computing device 100 may execute a childbirth nursing practice program using virtual reality and display a virtual reality image for childbirth nursing practice on the display device 200.

The display device 100 may be implemented as a Head Mounted Display (HMD) device or, depending on the implementation, as a display means such as a monitor. When the display device 100 is implemented as an HMD device, the display device 100 may output sound synchronized with a virtual reality image through an installed speaker. Of course, if the display device 100 is implemented as a monitor without speakers, sound synchronized with the virtual reality image may be output through a separate speaker device.

The user input device 300 can be implemented as a device that is worn or mounted on the learner's hand and can receive user interaction for childbirth nursing practice from the learner. For example, the user input device 300 may be implemented as a wearable input device such as an electronic glove that is worn on the learner's hand and detects the learner's hand movements. Additionally, the user input device 300 may be implemented as a joystick device as illustrated in FIG. 2 that has a plurality of buttons and an inertial sensor to detect the user's hand movements and button inputs.

Figure 2 is a diagram showing an example of a user input device according to an embodiment of the present invention.

Figure 3 is a flowchart for explaining a delivery nursing practice method using virtual reality according to an embodiment of the present invention.

Figures 4 to 12 illustrate content screens for childbirth and nursing practice using virtual reality according to an embodiment of the present invention.

Referring to FIG. 3, when a childbirth nursing practice program using virtual reality is first executed on the computing device 100 and a childbirth practice education course is selected by the learner, the computing device 100 displays the learner as a virtual patient on the display device 200. You can check patient information by providing virtual reality content that allows you to check the EMR (Electronic Medical Record) chart (S300). In step S300, the learner can manipulate a virtual object represented by a computer, laptop, or tablet computer to view patient information, doctor's prescriptions, and test results through the virtual patient's EMR chart.

Next, when entry into the delivery room is selected by the learner, the computing device 100 displays delivery 1, including a virtual nurse 41 and a virtual patient 43 lying on the delivery bed as illustrated in FIG. 4 on the display device 200. Virtual reality content that creates a delivery room situation corresponding to the period can be provided (S310). For example, when a learner enters the delivery room, the virtual patient is lying on the delivery bed with an electronic fetal monitor attached to her abdomen, and the virtual nurse says, “Last night, around 10:25, I was taken to the delivery room due to regular uterine contractions at 30-minute intervals.” It can be implemented to provide a message providing patient information, such as "I was hospitalized and saw dew around 11 a.m. yesterday." In addition, information such as the degree of uterine contraction and the baby's heart rate measured through the electronic fetal monitor, the patient's vital signs (blood pressure, pulse, respiratory rate, body temperature), and oxygen saturation can be provided through the electronic bulletin board.

The computing device 100 has the virtual nurse instruct the learner to perform a mission to check the blood pressure, pulse, respiratory rate, and body temperature of a patient that needs to be checked in the first stage of labor, and then receives a thermometer (51) from the learner in the delivery room, as illustrated in FIG. 5. ) can be used to measure the patient's body temperature or provide virtual reality content that receives user interaction such as checking blood pressure, pulse, respiratory rate, etc. on the virtual electronic bulletin board 52. For example, in order to receive user interaction for measuring body temperature, the computing device 100 highlights the thermometer 51, and when the learner selects the thermometer 51, it highlights the ear part of the virtual patient so that the user can use the thermometer 51. You can put it to your ear.

The computing device 100 can create an unexpected situation that may occur in the first stage of labor in a virtual space and assign a mission to the learner to check the problem. For example, as shown in Figure 6, an unexpected situation can be created in which a virtual patient complains of difficulty breathing, oxygen saturation decreases, and the fetal heart rate decreases. Additionally, the virtual nurse can ask the learner about the problem and check the problem through the patient monitor. And, as shown in Figure 7, items such as blood pressure, pulse, respiratory rate, body temperature, oxygen saturation, and fetal heart rate can be displayed on the screen and the correct answer can be received from the learner. Learners can check the electronic bulletin board, check the problem, and select the correct answer from the given options.

The computing device 100 may assign a mission for a learner to take to a virtual patient in an unexpected situation. For example, a virtual nurse can use a voice to instruct a learner on a mission to have a virtual patient move to the left side and encourage breathing.

When a user interaction corresponding to an action of turning the virtual patient to the left is input from the learner through the user input device 300, the computing device 100 can change the virtual patient's posture to the left-up position accordingly. . For example, the computing device 100 may display a user interface for changing the virtual patient's posture to the left side, and the learner may input a user interaction to change the virtual patient's posture to the left side through the user interface. Referring to Figure 8, a hand-shaped leader line (81) is displayed on the right side of the virtual patient's stomach lying on the front, the learner moves the virtual hand (83) to the position of the hand-shaped leader line (81), and then moves the gauge bar. When the gauge in (85) is filled to 100%, virtual reality content that causes the virtual patient to change the upper left corner to a drunken state can be provided.

When the learner completes all missions in the first stage of labor, the computing device 100 displays a virtual doctor 91, a virtual nurse 41, and a virtual patient 43 on the display device 200, as illustrated in FIG. 9. Including, virtual reality content that creates a delivery room situation corresponding to the second stage of labor can be provided (S320). In step S320, the virtual doctor tells the learner to look at the virtual patient's perineum, and when the learner moves his/her gaze in the direction of looking at the virtual patient's perineum from the front, information on the 7th stage of childbirth is sent to the virtual patient's perineum. and pelvic bones, and can be provided through a virtual fetus.

For example, the first stage (advance stage) in which the longest part of the fetal head passes through the pelvic entrance, the second stage (descent stage) in which the fetal body is pushed by intrauterine pressure, and the fetal head pushes against the pelvis as descent continues. Stage 3 (flexion stage), where the fetal head rotates to the widest part of the pelvis and descends (stage 4), stage 5 (head extension stage), where the fetal head turns its head as it reaches the entrance to the vagina, Stage 6 (external rotation stage), in which the fetal head is turned back to its original position, and Stage 7 (delivery stage), in which external rotation is completed and the fetal body expands as it touches the perineum, can be visually expressed on the screen.

The computing device 100 can direct the process of an episiotomy performed in the second stage of labor. For example, when a virtual doctor asks a virtual nurse for a disinfection tool, the virtual nurse can deliver the disinfection tool to the virtual doctor, and the virtual doctor can direct the process of disinfecting the virtual patient's perineum. Additionally, the virtual doctor instructs the virtual patient to undergo anesthesia and asks the virtual nurse for anesthesia tools. If the virtual nurse delivers the anesthesia tools to the virtual doctor, the virtual doctor can produce the process of anesthetizing the virtual patient's perineum. Next, the virtual doctor can request surgical tools from the virtual nurse, receive them, and then perform the process of making an incision in the virtual patient's perineum. After an episiotomy, the fetus can be shown sliding out of the virtual patient's body, the umbilical cord is cut, and an umbilical occluder is attached to the umbilical cord. Of course, during this process, it is possible to express some situations with audio or subtitles. Meanwhile, depending on the embodiment, it is also possible to implement virtual reality content so that the virtual nurse assigns the actions performed in the second stage of labor as a mission to the learner and receives appropriate interaction input from the learner.

Meanwhile, the virtual nurse can hand over the baby to the learner after birth and give them the task of placing the baby on a warmer and performing amniotic fluid suction. When the learner places the virtual baby handed over from the virtual nurse on the warmer, a user interface for the learner to perform amniotic suction can be displayed, and the learner can enter user interaction to perform amniotic suction on the virtual baby through the user interface. You can. For example, as shown in Figure 10, the amniotic fluid suction device 11 placed next to the warmer is highlighted and displayed, and the learner selects the amniotic fluid suction device and moves it toward the virtual baby, then presses a predetermined button on the user input device 300. You can click multiple times to enter user interaction for positive suction.

Meanwhile, if the virtual nurse gives the learner a mission to check the APGAR score, an APGAR score table can be displayed where the learner can check and enter the APGAR score. If any of the APGAR scores entered by the learner do not match the current status of the virtual baby, feedback can be given to the learner and the learner can be asked to re-enter it. Additionally, if the APGAR score is not 10 points, it can be implemented to display the phrase, "If the APGAR score is less than 10 points, you must check again after a certain period of time." and receive the score from the learner again after a predetermined time.

Meanwhile, the virtual nurse can give learners a mission to measure the baby's weight, and can also give the baby and the virtual patient a mission to put anklets and bracelets on. Next, the computing device 100 may display a user interface for measuring the baby's weight, and the learner may input a user interaction for measuring the baby's weight through the user interface. Likewise, the computing device 100 can display a user interface for filling anklets and bracelets on a baby and a virtual patient, and a learner can input user interaction for filling an anklet and bracelet on a baby and a virtual patient through the user interface. .

When the learner completes all missions in the second stage of labor, the computing device 100 displays virtual reality content on the display device 200 that creates a delivery room situation corresponding to the third stage of labor, including a virtual doctor, a virtual nurse, and a virtual patient. Can be provided (S330). In step S330, a situation in which a virtual doctor pulls the virtual patient's umbilical cord and removes the placenta can be expressed. Then, the virtual nurse examines the placenta, checks if there are any abnormalities, and reports it to the doctor. Next, the virtual doctor can express the situation of suturing the virtual patient's perineum.

After all virtual reality content corresponding to the third stage of labor is provided, the computing device 100 may provide virtual reality content that creates a recovery room situation corresponding to the fourth stage of labor, including a virtual nurse and a virtual patient (S340). In step S340, the phrase '30 minutes after birth, 4th stage of labor begins' may be displayed on the screen, and a situation is expressed in which the virtual patient complains of dizziness and the pad placed under the buttocks is stained red by blood spilled from the vaginal opening. It can be.

The virtual nurse can assign the learner a mission to massage the virtual patient's uterus while going to report the situation to the doctor. The computing device 100 may display a user interface for massaging the uterus of a virtual patient, and a learner may input user interaction for massaging the uterus of a virtual patient through the user interface. For example, as shown in Figure 8 above, a hand-shaped leader line is displayed on the virtual patient's abdomen, the learner moves the virtual hand to the position of the hand-shaped leader line, and the gauge bar is filled to 100%. It can also be implemented to receive user interaction for massaging by clicking a predetermined button of the user input device 300 several times.

Afterwards, when the virtual doctor enters the recovery room and asks the learner a question about the virtual patient's condition, a message asking to check the patient's monitor may be displayed on the screen. When a learner selects a patient monitor, the patient monitor's electronic bulletin board is displayed, and a message asking the learner to select a problematic item may be displayed on the screen. When a learner selects a problematic item, feedback can be provided as to whether the correct answer is correct.

And when the learner selects the correct answer to the problem item, the doctor can give the learner a mission to perform according to the problem item. For example, in a situation where blood pressure has dropped, the doctor asks the learner to mix a predetermined amount of oxytocin into the IV fluid, and the computing device 100 extracts the oxytocin drug with the syringe 21 as illustrated in FIG. 12 and administers the IV fluid 23. ) can display a user interface for injection, and the learner can enter the corresponding user interaction through the user interface.

Next, the computing device 100 can express a situation where the virtual patient's blood pressure returns to normal and stabilizes after the oxytocin drug is injected through IV fluid.

After all processes from the 1st stage of labor to the 4th stage of labor are performed in this way, the computing device 100 can end the labor nursing practice using virtual reality.
