Description

{MEDICAL DEVICE GATEWAY}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical device gateway, and more particularly, to a medical device gateway capable of performing medical data communication between a plurality of medical devices and a hospital information system.

Due to the development of information and communication, computer-based patient records have become commonplace in the medical field. Such medical information includes personal medical information such as family history, past history, and mental illness records as well as visual information such as X-ray.

Representative systems for processing and managing such medical information include an electronic medical record (EMR) system and a facsimile (Picture Archiving and Communication System: PACS). The EMR system includes medical record such as admission record, outpatient initial record, outpatient record, problem list, progress record, surgery / anesthesia record, discharge summary, consultation medical record and special treatment record, prescription execution linkage record, Nursing records such as observation record, special measurement record, nursing process, discharged nursing record, surgical nursing record and restoration nursing record, record of the patient's basic information and patient record such as patient reception information, It is a system that can integrate all the information about the patient without chart (chartless) by constructing the prescription record such as injection prescription, examination prescription and treatment / surgery prescription as an integrated database (DB).

Therefore, EMR is able to reduce the chart management cost, labor cost, various printing costs, etc. by computerizing without medical chart, medical care, nursing, prescription, It provides intervention to prevent medical accidents, improve efficiency of medical treatment and reduce redundant tasks, and to work efficiently and manage various statistics.

Fax (PACS) is an image storage and transmission system that stores and manages medical images photographed without film (filmless) as digital data, which is required in analog imaging medical devices such as conventional X-ray and CT. This PACS eliminates the cost of film management and film purchasing because the film is not needed, and it can improve the efficiency of the medical treatment because the medical image can be seen and diagnosed everywhere.

However, the conventional EMR has a problem in that it can not interoperate with the test information measured in a plurality of medical devices having various data interface standards, only by computerizing the text-based information recorded by the medical staff, the nursing staff, . That is, a plurality of medical devices have different data interface standards, and thus can not be interworked with the EMR system.

On the other hand, the management of the medical device has been carried out by the management team operated by the hospital or the A / S team of the company that has supplied the hospital equipment. In the case of medical equipment, it is very expensive, so if the equipment malfunctions, the hospital will suffer a huge financial damage. Therefore, the medical equipment is thoroughly managed. First, in case of expensive MRI equipment, The post-maintenance is underway. For filming equipment, the film exchange cycle may return once a month, depending on how much equipment is used, and may be longer if less equipment is used. To reduce losses due to medical device failure, .

In the case of the management system of the medical device used in the past, the replacement time is still left, but the film is replaced at a high cost. In the case of the inspection device or the surgical device, the post management system is operated after the trouble of the device occurs come. In this case, the hospital is not operated smoothly due to cost problems, and the patient is unable to perform the examination at a necessary point in time

An aspect of the present invention is to provide a medical device gateway capable of performing medical data communication between a plurality of medical devices and a hospital information system and monitoring normal operation of the medical device.

It is another object of the present invention to provide a medical device gateway that can determine a failure type of a medical device, generate solution information according to the failure type, display it on the outside, and transfer it to a hospital information system to support quick recovery of the medical device.

According to an aspect of the present invention, there is provided a medical device connector comprising: a medical device connection part having a plurality of ports corresponding to a plurality of medical devices; A detector for detecting a voltage or a current of the medical device connected to the port; A pattern data unit storing voltage or current usage pattern data for each operation type of the medical device connected to the port; And a controller for comparing the voltage or current data detected by the detector with the voltage or current usage pattern data to determine whether the medical instrument is operating normally.

The controller compares the voltage or current data with the voltage or current usage pattern data to determine that an abnormality has occurred in the medical device when the voltage or current data is out of a predetermined error range.

The controller may transmit the failure information to the hospital information system when it is determined that an abnormality has occurred in the medical device.

The pattern data unit may store failure pattern data including voltage or current pattern information for each type of failure of the medical device.

When the controller determines that an abnormality has occurred in the medical device, the controller can determine the type of failure of the medical device by matching the voltage or current data with the failure pattern data.

The control unit may generate solution information according to the failure type of the medical instrument and transmit the solution information to the hospital information system.

The solution information may include at least one of self-repairability, parts replacement, and external vendor request according to the failure type.

And a display unit for externally displaying whether the medical device is operating normally and the solution information.
