Description

Ubiquitous-health system for a patient management

The present invention relates to a ubiquitous-health system (hereinafter referred to as "U-health system"), and more specifically, to accurately measure the intake of the patient and the output of the excreted and discharged therefrom. The present invention relates to a U-health system for monitoring the patient and detecting the presence of risk factors in the feces to warn the medical staff to more accurately manage the patients.

The U-health system refers to a health care system that includes the prevention, diagnosis, treatment and health care of diseases provided "anytime, anywhere" by integrating ICT into the medical industry. The U-health is a development of e-health, which has recently emerged as a result of the development of early ICT, centered on health care consumers, and it is a state-of-the-art health network connected to physical spaces and networks covering the subjects and providers. Compared to e-health, which is limited to the exchange of electronic health information by connecting the electronic space of medical technology, the connection and application is a further upward concept.

The U-health system as described above may be divided into a service part that directly provides a remote medical service and an equipment and solution part for sensing and transmitting biometric information. Hospital type (U-Hospital), health-care (heal care), well-ness (Wellness) type and the like can be classified. The U-hospital type U-health is an intake of medical treatment, surgery, treatment, food taken by the patient or drugs administered orally / injected in a special space called a hospital, and drained from the patient's biological organs. (drainage / excretory) output measured by measuring the circulating blood volume (medical information) to the medical staff, and the database (Electronic Medical Record) information managed by the database automatically Measurement techniques such as updating.

In critically ill patients with cancer, kidney, and metabolic abnormalities, nutritional supplementation is artificially performed to control the circulation of blood to preserve or enhance the immune system's compensatory activity. In patients with low body weight or sensitive responses to micro-liquid changes, the accuracy of measurements of intake and excretion is an important indicator in determining the quality of treatment for medical services.

One example of an intake / excretion record sheet measured by a medical staff, such as a nurse, to measure and record a patient's intake and excretion in order to control a patient's circulating blood volume in an actual hospital is shown in FIG. 1. Referring to Figure 1, the intake includes oral intake of the meal (soup, cold, water, other foods such as rice) and nasal oral fluid (fluid), suspension, blood (blood) and the like. The excretion amount is urine, stool, as well as drainage of mucopurulent, which is held in the human body by vomiting, surgery, and treatment, suction sucked by an inhaler, etc. It includes.

The recording of the intake / excretion amount of the patient as shown in FIG. 1 is intended to monitor whether the circulating blood volume of the patient is improved after the medical staff prescribes a therapeutic formula for treating the patient and administers to the patient. In fact, in the cancer patient ward or intensive care unit, neonatal intensive care unit, emergency room, operating room, etc., a lot of energy is spent in performing medical tasks to measure food intake and excretion by time. In other words, the work of nurses is increasing. The intake / excretion amount of the patient is recorded in a database (DB) of an EMR (Electronic Medical Record) computer that manages hospital medical information.

An example of an H-hospital system that measures the intake and excretion of a patient using Radio Frequency Identification (RFID) / Ubiquitous Sensor Network (USN) has been filed by two professors, "Byung Hwa Lee", Graduate School of Public Health, Yonsei University.

The RFID tag 102 attached to the container 100 is an identification code of the container, and is connected to a database DB of the U-health terminal 500 shown in FIG. The container 100 is tracked and managed by inputting in advance the identification code of the RFID tag 102 of the container 100 and information such as food type, net quantity, date, time, container weight, etc. in the patient recording area.

That is, when the person in charge of the cooking chamber connects to the U-health terminal 500 of FIG. 2 using a computer terminal (not shown) provided in the cooking chamber, the computer terminal of the cooking chamber is the interface line 516 of FIG. The controller 506 is connected to the wired / wireless interface 502. At this time, when the custodian in charge inputs the patient's name (or patient number), the controller 506 accesses the food field stored in the recording area of the patient in the database 510 and transmits it to the cooking room computer terminal. Through the above process, the cooking chamber can view information on the food field of the patient who will provide the food on the monitor. At this time, the person in charge of the cooking room using the cooking room computer terminal food properties and container information, such as the date, time, food type, net amount (food weight), such as the container in step S50, S52 of Figure 6, that is, the container 100 When the information of the RFID tag 102 is input, the U-health terminal 500 of FIG. 2 is connected to the food property of the corresponding patient's food field of the DB 510 based on the patient number in step S54 of FIG. 6. By storing the container information it is possible to track the container 100 provided to the patient. Therefore, the information of the RFID tag 102 attached to the container 100 corresponds to the patient identification code.

As shown in FIG. 2, the intake detection node 200 illustrated in FIG. 3 is a state in which the RFID tag 102 of the container 10 matches the patient number after the patient ingests food. When the container 100 is placed on a plate, the RFID reader 202 reading the identification code of the RFID tag 102 attached to the container 100 and the weight of the container 100 placed on the plate are weighed. The weight sensor 206 for sensing, and the data transmission and reception unit 208 for transmitting the food intake information to which the identification code of the container is added to the weight information detected by the weight sensor 206. In this case, the data transmission and reception unit 208 processes the output of the RFID reader 202 and the data of the weight sensor 206 and output as transmission data as shown in Figure 3 and the CPU 210 It consists of a Zigbee chip 214 for transmitting the data output from the wireless channel.

The intake detection node 200 configured as shown in FIGS. 2 and 3 has an RFID reader 202 in the process S60 of FIG. 7 when the container 100 provided as a storage container for feeding nutrition to the patient is placed on a plate of the scale. Reads the information recorded in the RFID tag 102 of the container 100 and provides it to the CPU 210. At this time, the weight sensor 206 detects the weight of the container 100 placed on the plate in the process S60, S62 of Figure 7 and supplies the corresponding weight information to the CPU 210, the CPU 210 is S64 The intake information based on the container (RFID tag information) and weight detected in the process is transmitted through the ZigBee chip 214. That is, the food intake information to which the determined patient identification code (container RFID) is added is transmitted to the U-health terminal 500.

In the intake detection node 200 of the present invention, a configuration in which the RFID tag 102 is attached to the container 100 and the RFID reader 202 is attached to the scale has been described, but the RFID tag 102 is represented by a barcode. Note that the RFID reader 202 can be configured as a barcode scanner, which is obvious to those skilled in the art.

On the other hand, the excretion detection node 300 shown in Figure 2 has a unique identification code between the catheter 305 and the drain container 302 connected to the excretion sensor 310 connected through a connector (306) Include. In FIG. 2, an inlet hose 304a and an outlet hose 304b show an example of a urine drainage container in which upper and lower portions are formed, respectively, various drainage containers may be used. That is, one of the various drainage containers used in the hospital to select the drainage container made to easily drain and discharge the excrement accumulated in a specific biological organ during or after surgery, it is preferable to use a sterilization treatment. In FIG. 2, the drain plate 307 installed in the discharge hose 304b opens the discharge hose 304b when the waste filled in the drain container 302 approaches the storage limit of the drain container 302. It is for discharging the excreta filled in the drain container 302 to the outside.

As shown in FIG. 4, the excretion sensor 310 includes an outlet tube 312 connected between the catheter 305 and the drain container 302 of FIG. 2. The outflow tube 312 is preferably made of a transparent resin of a silicon material that can be sterilized, such as a conventional catheter, it is installed through the housing 328. Inside the outlet tube 312, a flow rate / fluid sensor 314 that detects the flow rate and the amount of fluid flowing therein and outputs a flow rate detection signal corresponding thereto is attached in the longitudinal direction.

The flow rate / fluid sensor 314 is a micro thermal micro flow rate / flow rate sensor based on MEMS technology manufactured on a silicon substrate, and an upper thermopile 313 and a lower thermopile 315 are formed on upper and lower portions, respectively. It is. The flow rate / fluid sensor 314 converts the temperature change of the two thermal piles 313 and 315 induced by the flow rate when the liquid waste flows into the outflow tube 312 into an output electrical signal to convert the flow rate detection signal. Output Such a flow rate / fluid sensor 314 is registered in Korean Patent No. 10-0362010 "Method of manufacturing a thermal micro flow rate / flow rate sensor" or "May 31, 1994, pp. 31, A, No. 5, for detecting the flow rate. It can be manufactured by applying the technology of the flow sensor published in "Design and manufacture of a silicon flow sensor".

On the upper end of the outflow tube 312, liquid excretion discharged from the catheter 305 is formed to guide the excretion guide screw thread (SCW) to be guided in the direction in which the flow rate / fluid sensor 314 is installed. Even if a small amount of excretion is discharged and discharged from the patient's biological organ by the excretion guide thread (SCW), the flow rate can be accurately detected by passing through the flow rate / fluid sensor 314.

A color sensor 316 is installed on an outer wall of the outflow tube 312 to detect a color of excrement flowing into the inside and output a color detection signal corresponding thereto. The color sensor 316 is composed of respective sensors for detecting red (R), green (G), and blue (B). The flow rate detection signal detected by the flow rate / fluid sensor 314 and the color detection signal detected by the color sensor 316 are input to the MPU 322 accommodated in the housing 328. An RFID tag 318, which is a unique identification code of the excretion sensor 310, is installed inside the housing 328, and information of the RFID tag 318 is input to the MPU 332.

The MPU 322 is set by the selection of the operation mode button 332, the up / down buttons 334, 336, the information of the initialization, drain container capacity, operation start date / time. For example, if the operation mode button 332 is pressed for 5 seconds or longer, an initialization mode for initializing all information stored in the internal memory, and a menu message for selecting an operation mode when only 1 second is selected, is displayed on the display unit 320. It is supplied so that the user can check the exterior of the housing 328.

More specifically, the first mode is the dose information of the drain container 302, the second mode is the patient identification code (corresponding to the patient name as the patient number), the third mode is for inputting the type and time of the excretion The menu, the fourth mode, is a start menu. If any one of the up / down buttons 334 and 336 is selected in the state where the start menu is selected, it operates as a start button. Therefore, the user can input the information such as feces type, drainage volume, date, time using the three buttons (332, 334, 336).

The MPU 322 accumulates the flow rate detection signal output from the flow rate / fluid sensor 314 and transmits the information of the total amount of excretion to which the patient identification code is added at a predetermined period through the air interface 324, and the color. The color detection signal output from the sensor 316 is analyzed and the warning message to which the patient identification code is added is wirelessly transmitted through the wireless interface 324 in response to the color being approaching a preset dangerous color. At this time, the wireless interface 324 is a data transmitter for wirelessly transmitting data output from the MPU 322 through a flat antenna 330 attached to one outside of the housing 328, ZigBee, WBAN Alternatively, any one selected from the WPANs may be used. In FIG. 4, reference numeral 326, which has not been described, is a battery for supplying operation power to each unit shown in FIG. 4.

The intake information and the total amount of excretion output from the excretion sensor 310 of the intake detection node 200 and excretion detection node 300, the warning message via the data collection device 400 U-health terminal 500 Is sent to. At this time, the data collecting device 400 is connected to the antenna 402 as shown in FIG. 5 and transmits data of the RF module 410 and the wired channel to transmit and receive the data frame received in the transmission frame of ZigBee, WBAN or WPAN A communication unit 406 including a LAN 412 and an RS-232C 414 to transmit and receive, and a main control unit (408) and a memory 407 to control transmission and reception data. And a display unit 404 for displaying the transmission / reception state.

The excretion detection node 300 shown in Figures 2 and 4 is operated as follows. After the medical staff performs the catheter 305 to drain and discharge the excrement accumulated in a specific biological organ during or after the operation to the outside, three buttons 332, 334, and 336 in step S70 of FIG. 8. Register the attributes of the drainage container corresponding to the RFID tag 318. The attributes of the drain container are the patient number, the capacity of the drain container, the date, the time, and the transfer time.

The attribute information of the drain container is stored in the internal memory of the MPU 322 shown in FIG. Then, if the medical staff sets the start mode using the three buttons 332 to 336 installed outside the excretion sensor 310 and the housing 328, the MPU 322 in the excretion sensor 310 is the process S74 of FIG. Read the output of the flow rate / fluid sensor 314 to detect the total amount of liquid (dung) flowing into the drain container 302 and accumulate, and retrieves whether the transmission time in the process S75. When it is determined that the preset transmission time has been reached, the MPU 322 detects information on the amount of fluid accumulated in the internal memory (the total amount of excretion) in step S76 and the patient number stored in the memory, that is, the patient identification code and the accumulation. The calculated total amount of excretion is transmitted to the U-health terminal 500 through the air interface 324 and the data collection device 400.

If it is determined that it is not time to transmit the information of the total amount of excretion detected in step S75, the MPU 322 of the excretion sensor 310 reads the output of the color sensor 316 in step S77, the color of the excrement detected in step S78 It is determined whether it is red, green, brown or black. If the excretion that is drained and discharged from the patient's body to outside is colored as above, it is blood, bile, oxidized bile or old bleeding, so the medical staff should be promptly informed and follow up.

If the color of the excrement detected in step S78 is not close to red, green, brown, or black, the operation is repeated from step S71, and if the color of the detected excrement is close to the color above, the U-health terminal in step S79 ( 500) transmits a warning message including the patient identification code. In S8 and S73 in FIG. 8, the drainage state is initialized when the drainage container 302 is exchanged.

Meanwhile, the U-health terminal 500 shown in FIG. 2 analyzes the patient identification code included in the intake information and the total excretion information received through the data collection device 400 and based on the analyzed patient identification code. Search for the recording area of the patient in the DB 510 in which the information of the EMR is stored. Thereafter, by storing and updating healthcare information such as food intake information and total excretion information received in the searched patient's record area, the intake information and excretion information of the patient are linked with the DB 510 in which the information of the EMR is stored. Is updated.

Referring to Figure 9 describes the operation of the U-health terminal 500 as follows. &&

When data is received through the data collection device 400 shown in FIGS. 2 and 5, the U-health terminal 500 analyzes the type of data received in steps S80, S81, and S82 of FIG. 9. To this end, the intake detection node 200 and the excretion detection node 300 includes data for determining the type of message in the header of the transmitted frame.

If the data received in step S80 is determined to be intake information, the control unit 506 of the U-health terminal 500 calculates the food net amount by subtracting the container weight from the intake information received at step S83, that is, the weight information. In addition, the current intake information is stored in the database BD corresponding to the patient identification code.

If it is determined that the data received in step S81 is excretion information, the control unit 506 of the U-health terminal 500 analyzes the excretion amount information received in step S84 to obtain information on the total discharge amount, and the patient identification code. The current time is added to the excretion amount information in the database BD corresponding to the stored data.

If it is determined that the data received in step S82 is a warning message, the control unit 506 of the U-health terminal 500 analyzes the warning message received in step S85 in the database BD corresponding to the received patient identification code. The information of the attending physician is acquired and a paging message including the received color information is supplied to the radiopager 514. At this time, the radio pager 514 calls the pager carried by the attending physician to inform the patient that an urgent medical condition has occurred. Here, a pager and a radio pager refer to a mobile communication terminal possessed by a medical staff, for example, a wireless pager, a mobile phone, a personal digital assistant (PDA), etc., or call the mobile communication terminal, or receive a short message service (SMS) message or MMS. (Multi-media Message Service) A device that transmits a message.

By the above process, healthcare information such as intake and excretion amount stored in the DB 510 of the U-health terminal 500 can be easily monitored by a medical staff. This process is described below.

When a medical practitioner such as a doctor or a nurse inputs a patient's name or patient number by the input unit 504 including a keyboard and a mouse, the controller 506 reads healthcare information corresponding to the input patient name or patient number. Display on the monitor. In this case, the health care information is provided by the food intake information and the excretion information described above by time zone and date to provide a foundation for the medical staff to more accurately and precisely control the circulating blood volume of the patient.

The excretion sensor 310 of the above-described embodiment detects the excretion amount of the excretion discharged and discharged through the catheter 305 using the flow rate / fluid sensor 314 and the color sensor 316 and only detects the color of the excretion However, a biosensor for detecting urine specific gravity, uric acid, urine sugar, and the like is installed in the inlet and outflow tube 312 to detect urine secretion, uric acid, and urine sugar from the excreted and discharged through the catheter 305, thereby By transmitting healthcare information to the U-health terminal 500, EMR management may be more diversified.
