And a medical information database 180 that stores information about the patient, an electronic form prepared for the patient, and instructions on treatment actions provided by the medical practitioner to the patient in the field.

Referring to the operation of the mobile diagnostic support system according to the present invention having the structure as described above in detail.

When a doctor requests a patient in a hospital, a request letter arrives, and when a manager inputs basic patient information and medical information to the medical information server 170, a patient ID is generated in the patient master file, and the medical information server ( 170 registers the generated patient ID and stores the input information in the corresponding ID.

In addition, if the medical personnel are selected according to the region or history of the patient, the person in charge is combined with the ID of the patient. The selected medical practitioner inquires the patient to determine the first visitor, and inputs a schedule as his ID on the medical information server 170. When the person in charge requests a schedule from the outside using the PDA 120, the medical information server 170 transmits the ID and the visit date of the patient to the PDA 120 through the communication network 140.

The medical staff in charge checks the ID and visit date of the patient displayed on the PDA 120 and visits the patient according to a schedule. The healthcare provider refers to the patient's basic information with the ID of the patient in charge at home using the PDA 120, and if it is necessary to input new information, the healthcare worker additionally inputs the patient's new information into the PDA 120. Save it.

In addition, the medical worker is connected to the medical information server 170 using the PDA 120, and downloads the electronic form and the diagnostic and treatment instructions stored in the medical information database 180 through the medical information server 170. . Here, the electronic form is a document prepared by the attendant for the patient, and the diagnosis and treatment instructions are the instructions provided by the attendant for the diagnosis and treatment of the patient. In the present invention, the diagnosis and treatment instructions provided in the electronic form and the current document is built in the medical information database 180 so that medical personnel can download the PDA 120 in the field and perform the actual treatment.

The medical worker inputs and stores the patient's state by using an electronic format sheet downloaded to the PDA 120 in the field and inquires diagnosis and treatment instructions to perform the required treatment according to the patient's state.

For example, the diagnosis and treatment instructions downloaded from the medical information server 170 by the medical worker for the blood test of the patient are illustrated in FIG. 5. The medical worker performs the blood test of the patient through the process as shown in FIG. At this time, each step is displayed sequentially, it is preferable that the next step is displayed only if the medical practitioner checks directly on the PDA 120 to perform the corresponding step. In this way, the omission of the treatment by mistake can be prevented.

In addition, when the diagnosis and treatment instructions are changed, the diagnosis and treatment instructions may be easily changed by modifying data stored in the medical information database 180.

Diagnosis and treatment instructions can also be written in rule-based conditional expressions, as shown in FIG. 6.

In the case of FIG. 6, for example, rule 01 is used to distinguish between providing diagnosis and treatment. That is, the same rule number is given to indicate each step in the same diagnosis. 'SEQ' indicates the order in the service. That is, the operation of 001 is performed first and the designated operation is performed according to the execution result.

In Rule 01, the practitioner measures the patient's temperature and checks if the measured patient's body temperature is less than 36.5 degrees. If the body temperature is lower than 36.5 degrees, the action marked 'Y', that is, the patient's body should be warmed. If the measured patient's body temperature is greater than 36.5 degrees, go to the action labeled 'N', ie SEQ 002, and check if the patient's body temperature is greater than 37 degrees. If the patient's body temperature is greater than 37 degrees, go to the operation labeled 'Y', that is, go to SEQ 003 and check for lung noise. If the patient's body temperature is less than 37 degrees, the patient's body temperature is normal, so record the body temperature is normal and exit from rule 01. In SEQ 003, if there is pulmonary noise, the action indicated by 'Y', that is, removing the patient's expectoration, and if there is no pulmonary noise, the action indicated by 'N', that is, iced to cool the patient's body temperature.

In FIG. 6, for convenience, an operation according to each condition is briefly summarized, but in actuality, the operation is described in detail. In addition, each step is not displayed at the same time as shown in Figure 6, but only shows the necessary parts for each step.

For example, the first time a healthcare practitioner opens diagnostic and treatment instructions related to temperature measurements, the screen 'Measure temperature' first appears. Then, the medical worker measures the body temperature of the patient using the bio-signal measuring instrument (110). The measured body temperature data is transmitted from the biosignal measuring instrument 110 to the PDA 120 through the short range wireless communication unit 115 and 126. Then, the control unit 122 of the PDA 120 confirms the conditional expression of the diagnosis and treatment instructions. Check whether the measured body temperature data corresponds to 'yes' or 'no' of the conditional expression and display the contents described in 'Y' or 'N' of the diagnosis and treatment guideline. For example, if the measured body temperature is 36 degrees, the contents described in 'Y', that is, "Wrap the patient to keep warm with a blanket, etc." On the contrary, if the measured body temperature is 38 degrees, the control unit Reference numeral 122 denotes the operation described in 'N', that is, the operation of the conditional expression in SEQ 002 is performed by going to SEQ 002. In this way, the healthcare practitioner indicates the appropriate operation to be performed by the medical practitioner according to the measured biosignal. Can take appropriate action according to the patient's condition.

On the other hand, it is also possible to have a medical practitioner automatically select which diagnosis and treatment guidelines to select according to the patient's medical history. In other words, by connecting the diagnosis and treatment instructions to be taken to the patient database, it is possible to enter the patient ID only to select the appropriate diagnosis and treatment instructions. Alternatively, it is possible for a healthcare practitioner to view and enter a patient's condition so that appropriate diagnostic and treatment instructions are selected. For example: 1) high fever, 2) cold, 3) unconscious, 4) severe coughing, 5) sputum simmers, 6) vomiting blood, 7) vomiting food, etc. Selecting the current patient's state from among the various illustrated states such that diagnostic and treatment instructions are selected accordingly.

On the other hand, the medical practitioner performs the necessary treatments for the patient and stores the diagnosis and treatment results for the patient in the electronic form downloaded to the PDA.

Then, when a medical worker sends a request to the medical information server 170 to transmit the analysis result of the patient stored in the PDA 120, the PDA 120 receives the analysis result of the patient through the wireless communication unit 125 The data is transmitted to the management computers 160a to 160n or the medical information server 170. The medical information server 170 updates the analysis result of the corresponding patient stored in the medical information database 180 with the ID of the medical worker who requested the transmission.

In addition, the mobile diagnosis support system of the present invention can perform tasks such as patient management, medical personnel management, work management, service management, etc. in addition to helping diagnosis and treatment using a PDA.

Patient management is to manage the patient's information and history, and the patient's registered and terminated patient's information that needs diagnosis and treatment. Medical staff management is to manage the information of the person in charge and register new medical workers. Work management is to manage the medical staff's work schedule time and individual holiday schedules. Service management is in charge of patient management, visit schedule management, patient condition registration, diagnosis and treatment behavior registration, and referral management.

Therefore, in the case of a patient who is inconvenient to move, even if the patient does not visit the hospital directly, the above-described process can be provided to diagnose the health state of the patient in the field and receive the corresponding diagnosis and treatment services. .

In addition, the medical practitioner in the field can use the PDA to query the patient's information and medical history, and has the advantage of transmitting the patient's data to the medical information server in real time through a wireless communication network.

In the above, the present invention has been described with reference to some examples, but the present invention is not limited thereto, and a person of ordinary skill in the art may make many modifications and variations without departing from the spirit of the present invention. I will understand.
