Description

MOVABLE DISEASE INSPECTION APPARATUS AND METHOD FOR DETERMINING TO TRANSFER A SELF-ISOLATION PATIENT TO HOSPITAL

The present invention relates to a portable disease testing apparatus and method for determining transfer of a self-isolated patient to a medical institution such as a hospital. Specifically, the present invention determines the disease severity of a self-isolated patient using image analysis based on questionnaire responses, biosignal data, and machine algorithms, and when the disease severity is greater than or equal to a threshold value, transfer to one or more hospitals and other medical institutions after requesting transfer A mobile disease testing apparatus and method for determining transfer to a medical institution where transfer is accepted.

Recently, the spread of infectious diseases such as SARS, MERS, and Corona virus has become a social problem. If the number of people suspected of an infectious disease in a community increases explosively due to the spread of an infectious disease, medical institutions, such as hospitals, cannot immediately accommodate all suspected infectious diseases. In the case of the corona virus, a small number of people suspected of having an infectious disease were not accommodated in medical institutions and were self-quarantined.

It is difficult to accurately determine the severity of the disease through a simple questionnaire, and it can only be determined when a patient visits a medical institution. It is difficult to accurately determine the severity of the disease for suspected infectious disease individuals in self-quarantine. Home isolation is reasonable for mild patients, but a significant number of self-isolation patients had severe disease, resulting in a large number of deaths during self-isolation.

Therefore, there is a need for a portable disease testing apparatus and method that can visit a patient in self-quarantine and inspect the disease severity with high reliability.

In judging the severity of the disease, only the response of questionnaires such as past medical history and biosign data such as body temperature/blood pressure may be insufficient to judge the severity of the disease for a specific disease. Imaging of specific areas such as the lungs can increase the accuracy of disease severity judgment for specific diseases such as coronavirus. In particular, in the case of a patient who needs immediate transport to a hospital, imaging may be decisive data.

A doctor's visit to a patient with a portable disease testing device for image reading is inefficient considering the absolute shortage of medical resources when an infectious disease spreads. When image reading using a machine algorithm is used, it is possible to generate image reading data having reliability above an appropriate line. If data of a patient suspected of serious disease severity as a result of reading the image using a machine algorithm is selectively transmitted to a medical institution, a specialist located in the medical institution can efficiently determine the patient's disease severity.

Therefore, it is a mobile disease that can comprehensively determine disease severity through imaging and reading as well as bio-sign data such as questionnaire response and body temperature/blood pressure/pulse rate, and support transmission and reception of patient data with disease severity above a threshold value There is a need for an inspection apparatus and method.

The decision on whether to transfer to a medical institution is ultimately based on a judgment on patient data in the medical institution and a judgment on whether the patient is acceptable in the medical institution. Determination of whether each of the plurality of medical institutions accepts the same patient data may vary according to the patient acceptance status of each medical institution. If a transfer request message including patient data is sent to one or more medical institutions based on the current location and transfer to the medical institution that has received the transfer acceptance message is decided, the medical institution will make a final decision on the patient data together with the medical institution. The most reasonable transfer can be performed in consideration of the current status of patient acceptance.

Accordingly, there is a need for a mobile disease testing apparatus and method capable of transmitting a transfer request message including patient data to one or more medical institutions and determining a transfer destination medical institution according to whether a transfer acceptance message is received.
