The infusion amount measuring device table of the authentication center 400 may store and store the identification numbers of each of the plurality of infusion amount measuring devices 100 when the hospital is provided with a plurality of infusion amount measuring devices 100.

Depending on the embodiment, the infusion amount measuring device 100 may include an acceleration sensor that checks whether the patient moves when the patient moves together with the infusion amount measuring device 100.

When a patient is hospitalized, it is not necessarily in the bed, and may take a walk or go to the bathroom. Therefore, while the patient is administering the infusion solution, it moves together with the infusion bag. In this case, the infusion amount measurement device 100 may not accurately collect the infusion amount information due to the cause of shaking of the infusion bag. There may be an error in the amount of sap information.

The infusion amount measuring device 100 according to the present embodiment may provide accurate infusion amount information by weighting a correction value to the collected measured value in order to reduce an error in the infusion amount information that occurs when the patient moves with the infusion bag. That is, when the acceleration sensor checks whether the patient is moving and it is recognized that the patient is moving, the infusion amount measuring device 100 may prepare to add a correction value to the infusion amount information collected and transmitted.

To this end, the main server 300 that receives the infusion amount information from the infusion amount measuring device 100 according to the present embodiment may include an abnormality information detecting unit that interlocks with the acceleration sensor of the infusion amount measuring device 100.

If it leaves, it is possible to transmit an emergency signal indicating that the patient is in an emergency state.

The reference setting range of temperature and humidity, for example, can be considered to be within the reference setting range if the temperature is between 26 (℃) and 27 (℃). If the temperature is outside this range, it is assumed that the patient stays in a place with high humidity, such as a bathroom. can do. In this case, if the temperature is out of the standard setting range and is maintained for a certain period of time, it can be estimated that the patient has an accident in the bathroom, etc., and a caution signal can be transmitted. Here, the attention signal may be transmitted through not only the nurse terminal 200 but also other warning means.

According to an embodiment, the infusion amount measuring device 100 includes a temperature and humidity sensor that collects temperature and humidity information around the patient, but the movement status of the patient is not confirmed by the acceleration sensor, and the collected temperature and humidity information is set within a set range. If it goes away, a warning signal indicating an abnormality in the surrounding environment can be transmitted.

If the temperature and humidity information collected while the patient's movement status is not confirmed is out of the set range, it can be estimated that an abnormality has occurred in the environment such as a ward where the patient's bed is located. Can be transmitted.

Meanwhile, when the authentication signal is received from the authentication center 400, the main server 300 may store the amount of fluid information corresponding to the authentication signal by a blockchain technology.

According to an embodiment, the main server 300 may be connected to the first node server and the second node server through the Internet communication network 500 to form a blockchain network.

That is, the main server 300 converts the amount of fluid information matched with the patient's personal information into block data and transmits it to the first node server and the second node server, and blocks together with the first node server and the second node server. A chain network is formed, but when a request is made to confirm forgery or alteration of the amount information, the information held by the main server 300 itself and the information held by the first node server and the second node server are compared with each other to forgery. You can judge whether or not. That is, the main server 300, the first node server, and the second node server are synchronized to store necessary information in real time, and a private block chain network technology is applied to prevent forgery and alteration.

Here, the first node server may refer to a local server 350 of a hospital receiving services from a fluid monitoring service company, and the second node server may refer to an auxiliary server for configuring a block chain.

The main server 300 may secure data integrity by configuring a blockchain security system together with the first node server and the second node server.

The main server 300 may collect and store information that needs to be secured, such as patient personal information and medical information, and it is necessary to transmit such information to the outside. For example, when a patient moves to a higher hospital, it is necessary to transmit the patient's medical information to the higher hospital as well. In this case, a problem such as data error or forgery may occur in the process of transmitting information through the Internet communication network 500, and forgery may be prevented by configuring a blockchain network as a security system to prevent this.

2 schematically shows a method of managing fluid amount information based on the IoT according to an embodiment of the present invention. FIG. 2 illustrates a method of operating a medical IoT-based fluid monitoring system according to an embodiment of the present invention of FIG. 1.

In the medical IoT-based fluid amount information management method according to an embodiment of the present invention, when a patient is hospitalized, the personal information including the patient's personal information, the patient's ward information, and the bed information are identified by the fluid amount measuring device 100.

Medical information transmission step (S210) to be transmitted to;

Infusion amount measuring device authentication step (S220) of authenticating the infusion amount measuring device 100 by transmitting the identification number of the infusion amount measuring device 100 from the unique information received by the main server 300 to the authentication center 400 ; And

When the main server 300 is authenticated by the infusion amount measuring device 100 from the authentication center 400, the infusion amount information for transmitting the infusion amount information corresponding to the authenticated infusion amount measuring device 100 to the terminal of the nurse Transmission step (S230); may be configured to include.

According to an embodiment, in the step of transmitting the infusion amount information (S230), when the main server 300 is authenticated with the infusion amount measuring device 100 from the authentication center 400, the And an external transmission step of storing the infusion amount information and the unique number corresponding to the infusion amount information, and transmitting the infusion amount information and the unique number to the outside after securely setting the infusion amount information and the unique number by blockchain technology.

The implementation process of the fluid amount monitoring system according to an embodiment of the present invention will be described with a specific example.

For example, a case where a plurality of fluid amount measuring devices 100 are rented or purchased from a fluid amount monitoring service provider A in hospital B will be described.

The infusion amount measuring device 100 provided by the service provider A may be assigned a unique identification number, respectively. Here, the'identification number' may mean an address that is assigned as a unique number to each manufactured device according to an embodiment, for example, a'MAC address'.

The service provider A provides the infusion volume measuring device 100 to hospital B, while at the same time providing the identification number of the infusion volume measuring device 100, the IoT authentication center 400 operated by the service provider A, which means a kind of'authentication server'. ) Can be saved. Accordingly, the service provider A stores information on which hospital the infusion amount measuring device 100 provided by the company is being used in the IoT authentication center 400.

When a patient is hospitalized, first, the patient's personal information such as the patient's name, sex, and age is recorded in the EMR, and such personal information may be stored in the local server 350 of hospital B. At this time, when the ward and bed in which the patient is hospitalized are determined, the infusion volume measuring device 100 matching the ward and bed is determined, and the ward information and bed information and the identification number of the infusion volume measuring device 100 corresponding thereto are determined. It is matched and transmitted to the main server 300 together with the patient's personal information and stored.

Depending on the embodiment, the patient's personal information, the corresponding ward information and bed information, and the identification number of the infusion amount measuring device 100 corresponding thereto are matched in the local server 350 of the hospital and then transmitted to the main server 300. In some cases, each information may be transmitted to the main server 300 and then matched in the main server 300.

For example, when the infusion amount information is transmitted to the main server 300, the identification number of the infusion amount measuring device 100 that transmits the infusion amount information is also transmitted, and the patient's personal information, bed information, and Hospital room information can also be transmitted together. In this case, the patient's personal information, hospital room information, bed information, and identification numbers of the matched infusion measuring device 100 are all mapped and stored in the main server 300.

Subsequently, while the nurse administers fluid to the patient, when the infusion volume measuring device 100 that matches the patient's room information and bed information is switched on, the infusion volume measuring device 100 displays the fluid volume information of the infusion bag administered to the patient in real time. It is collected and transmitted to the main server 300. In this case, the sap amount information may be encrypted and transmitted to the main server 300. In this case, since the infusion amount information corresponds to the dose information in which the infusion is administered to the patient, information on whether the patient has administered the infusion amount based on the infusion amount information may also be stored in the main server 300.

At this time, an authentication process is required in order for the nurse to access the main server 300 through a nurse terminal 200 such as a PC or a mobile phone and receive information on the amount of fluid from the main server 300.

That is, when the nurse switches the infusion amount measuring device 100 on (On), the infusion amount information from the infusion amount measuring device 100 is transmitted in real time to the main server. At this time, when the nurse terminal 200 requests the main server 300 for information on the amount of infusion amount of the patient, the main server 300 uses the IoT authentication center 400 to determine the authenticity of the information on the amount of infusion received from the infusion amount measuring device 100. ) To request authentication of the infusion amount measuring device 100. That is, the main server 300 transmits the identification number of the infusion amount measuring device 100 to the IoT authentication center 400 in the manner of an authentication request. Then, the IoT authentication center 400 compares the identification number received from the main server 300 with the identification number previously stored in the infusion amount meter table of the IoT authentication center 400, and transmits an authentication signal to the main server 300 when they match. .

When receiving the authentication signal from the IoT authentication center 400, the main server 300 confirms that the infusion amount measuring device is a product used by Hospital B, and recognizes the infusion amount information transmitted from the infusion amount measuring device as true information. In the present specification, the meaning of true information and fake information may mean, for example, whether a document is genuine information that has not been forged or is forged information.

When the infusion amount information transmitted from the infusion amount measuring device 100 is recognized as true information, the infusion amount information is provided to the nurse terminal 200 as a ratio.

That is, the infusion amount monitoring system according to the present invention determines the authenticity of the infusion amount information transmitted by the infusion amount measuring device through the identification number of the infusion amount measuring device via the IoT authentication center 400, and when it is determined that it is true information, the corresponding amount of infusion It is to provide information to the nurse terminal 200.

On the other hand, in the main server 300, thus authenticated sap amount information is accumulated and stored. The infusion amount information may be information on the dosage amount of the infusion solution. Therefore, such information is medical information and requires security.

Therefore, a first node server and a second node server that exist separately from the main server 300 and that can form a block chain network together with the main server 300 are provided to share the blocked data using at least three servers. By doing so, forgery and alteration of information can be prevented. Here, the first node server and the second node server are not necessarily a single server, and may form a plurality of first node servers and a plurality of second node servers, respectively.

For example, information on when and for what treatment a patient A, who was admitted to hospital A, was administered what fluid, as medical information, requires security when exporting the information.

In this case, the local server of hospital A (meaning the first node server) and the main server and auxiliary server of the service provider (meaning the second node server) are The group of information on whether or not withdrawn is blocked and copied so that the main server, the first node server, and the second node server can each store the same information.If the information is later exported to the outside, what information will be sent to whom and when. The information on whether to be exported is compared with the existing information stored by the main server, the first node server, and the second node server to determine the authenticity of the information. Information can be kept secure in a way that the server stores.
