4 is a flowchart illustrating a method for controlling a room environment using a hospital information system according to an exemplary embodiment of the present invention. The room environment control method using the hospital information system shown in FIG. 4 uses the room environment control system described above with reference to FIGS. 1 to 3. Referring to FIG. 4, a method for controlling a room environment using a hospital information system according to an embodiment of the present invention includes a hospital information obtaining step (S10) of obtaining hospital information necessary from a hospital information database (110 of FIG. 1); Using the hospital information obtained in the hospital information acquisition step (S10) using the optimal environmental index calculation step (S20) and the optimal environmental index calculation step (S20) for each hospital room It includes an environmental control step (S30) for controlling the environmental control unit 130 installed for each.

In the hospital information acquisition step (S10), the optimal environmental index calculation unit (150 of FIG. 1) obtains hospital information data necessary for calculating the optimal environmental index from the hospital information database (110 of FIG. 1). Hospital information acquired by the optimal environmental index calculation unit (150 of FIG. 1) in the hospital information acquisition step (S10) is the name of the patient, the severity of the disease, the age of the patient stored in the patient information storage unit (111 of FIG. 2) And information on the number of guardians of the patient, the age of the guardian, and the information of the number of guardians of the patient, the location of the ward and the room information of the ward, and the guardian information storage unit (113 of FIG. 2). Includes gender and guardian's time of arrival.

In the optimal environmental index calculation step (S20), the optimal environmental index is calculated using the hospital information obtained in the hospital information acquisition step (S10). Optimum environmental index calculation step (S20) is performed by the optimum environmental index calculation unit (150 of FIG. 1) having the configuration described above. The optimum environmental index calculated in the calculation of the optimal environmental index (S20) refers to an optimal temperature, humidity, and air pressure suitable for each of the plurality of hospital rooms. That is, the information on the patient, the information on the room and the caregiver provided from the hospital information database (110 of FIG. 1) through the optimal environmental index calculation step (S20) performed by the optimal environmental index calculation unit (150 of FIG. 1). Based on the information on the environmental index, such as temperature, humidity and air pressure for each of the plurality of rooms is calculated. In the calculation of the optimal environmental index (S20), a weight value considering the severity and age of the disease is applied to the reference temperature (or humidity) set to an appropriate value based on the patient according to the patient, and the weight is also applied to the caregiver to optimize the room. Environmental index is calculated. It is desirable that greater weights be applied to patients than to caregivers, greater weights to patients with severe severity, and greater weights to older patients or caregivers. In addition, information on the ward of the hospital information database (110 of FIG. 1) may also be used to calculate the optimal environmental index. The location of the ward in the ward and the location of the patient in the ward (such as the window or corridor) may be applied to the weight.

Table 1 below shows an example of a calculation table used for calculating the optimal environmental index in the optimal environmental index calculation step shown in Figure 4, for the example of calculating the optimal temperature in the four-bed room.

Bed No. Patient (path name) Reference temperature Default weight Added weight Weighted sum /

Referring to Table 1, patient 1 of disease name 1 and guardian 1, a guardian of patient 1, stay in the room in response to bed 1, and guardian 2-1, guardian of patient 2 and patient 2, in response to bed 2, Guardian 2-2 stays, and patient 4 of disease 3 stays in response to bed 4. In Table 1, the reference temperature is set differently to the appropriate temperature according to the disease name in the case of patients, and the same temperature is set in the case of caregivers. In Table 1, the default weight depends on the name of the patient. For example, a patient with a disease sensitive to room temperature has a higher weight. For caregivers, the default weight is lower than for patients. In Table 1, additional weights are applied differently according to age and gender. As shown in Table 1, the weight ratio is calculated according to the patient and the caregiver, and the optimal temperature of the corresponding room can be calculated based on the weight ratio. For the example in Table 1, the optimum temperature is calculated to be 22.9 ° C. In addition, even if the patient's age and the caregiver's age are the same, the weight is applied to the patient.

In the environmental control step (S30), the optimum environmental index calculated for each room in the optimal environmental index calculation step (S20) is maintained in the corresponding room. Environmental control step (S30) is carried out by the environmental control unit (130 of Figure 1), the environmental control unit (130 of Figure 1) is the environmental environmental control step (S30) to the target environmental value calculated for each room in the target value The heating device (131 of FIG. 3), the cooling device (132 of FIG. 3) and the humidifier (133 of FIG. 3) are controlled. When the environmental control unit is provided with an air pressure adjusting device, the air pressure in the room may also be maintained in an optimal state in the environmental control step (S30).
