1 is a view showing an extracorporeal diagnostic apparatus according to some embodiments.

When the extracorporeal diagnostic apparatus includes the blood test apparatus 100, the blood test apparatus 100 may be configured as shown in FIG.

The blood testing apparatus 100 receives an examination medium on an examination medium insertion surface 120 of a loading section 110 including blood collected from a patient, analyzes the blood contained in the examination medium, (140).

Here, the inspection medium is formed so as to contain blood as a target to be inspected. The inspection medium may have a disk shape, a cartridge shape, or the like. One embodiment of the inspection medium is described in detail below with reference to FIG.

In addition, the blood testing device 100 can start the inspection of the blood to be inspected through a predetermined trigger signal notifying the start of the inspection. For example, the display unit 140 may be a touch screen in which a display panel and a touch pad are combined. Then, a user interface screen, which is a menu screen for conducting a blood test, is displayed through the display unit 140. Here, the user can touch the 150 button, which is a predetermined button included in the menu screen, to start the blood test.

Also, the blood test apparatus 100 may be manufactured in a portable size that can be moved as shown in FIG. 1, and may be mounted on a transfer means for moving an emergency patient such as an ambulance or an ambulance helicopter.

The blood test apparatus 100 can determine the validity period of the test medium before starting the blood test. A method for the blood tester 100 to acquire the valid period of the inspection medium and determine whether the validity period of the inspection medium is expired will be described later with reference to FIG. 2 and FIG.

When the expiration date of the test medium is used, errors may occur in the analysis results of the test object, for example, the reagent contained in the test medium and the test object do not react normally. In addition, the patient or the caregiver can raise the problem about the analysis result. Therefore, the user needs to be careful not to use the inspection medium whose expiration date has expired.

However, for economic reasons such as cost reduction, the user may intentionally use an expired inspection medium. Further, when the user can arbitrarily set the time information of the extracorporeal diagnostic device, there is no way to prevent such exploitation on the extracorporeal diagnostic device system.

Also, when the time information of the extracorporeal diagnostic device is set based on the time difference of the area where the extracorporeal diagnostic device is located, the extracorporeal diagnostic devices located in different areas can differently determine whether the validity period expires for the same test medium. For example, an in vitro diagnostic system located in Korea can be set to local time (+09: 00) based on Universal Time Coordinated (UTC) Time (+00: 00). Therefore, it can be concluded that the in vitro diagnostic system located in Korea for the same inspection medium has expired and that the in vitro diagnostic system located in the UK has not expired.

The case where the validity period has not expired for the inspection medium whose expiration date has expired is more problematic than the opposite case, depending on the region where the in vitro diagnostic system is located.

In addition, there is a case where an inspection medium whose expiration date has expired without intention of the user due to a mechanical defect is used. For example, when an error occurs in a system that manages time information of an extracorporeal diagnostic device, a user can use an inspection medium whose expiration date has expired.

Conversely, the user needs to set the time information of the extracorporeal diagnostic device at an arbitrary time according to need or according to the purpose. For example, when the time information of the extracorporeal diagnostic device is adjusted to the time difference of the region where the first delivery is made, the user needs to set the time information of the extracorporeal diagnostic device in accordance with the time difference of his / her location. In addition, in order to record predetermined time information in the analysis result or the analysis report of the in vitro diagnostic device, it is necessary to set the time information of the in vitro diagnostic device to an arbitrary time.

Accordingly, the present invention is applicable to a case where a user abuses an inspection medium whose expiration date has expired, a case where the validity period of the inspection medium is judged differently according to the time lag in the area where the in vitro diagnostic system is located, An extracorporeal diagnostic device capable of preventing the use of a medium. At the same time, the present invention provides an extracorporeal diagnostic device in which the user can set the time information of the extracorporeal diagnostic device at an arbitrary time, if necessary.

2 is a block diagram of the extracorporeal diagnostic device 200 according to some embodiments.

2, an extracorporeal diagnostic device 200 according to some embodiments includes a loading unit 210, a first clock unit 221 and a second clock unit 222, a sensor unit 225, a controller 230, And an analysis unit 240.

The loading unit 210 receives the inspection medium. Here, the inspection medium is a medium including an object to be inspected such as blood and body fluids. The loading unit 210 may correspond to the loading unit 110 shown in FIG. Specifically, the loading unit 210 may include a medium inserting device for receiving the inspection medium, and the shape of the loading unit 210 may vary depending on the inspection medium.

In FIG. 1, a case where the inspection medium has a disc shape is shown as an example. In this case, the loading unit 110 may include a disc tray (not shown) for inserting the disc as a medium inserting apparatus.

Specifically, the loading unit 110 drives the disc tray so that the disc can be mounted on the disc tray.

As another example, the inspection medium may have a cartridge shape. In this case, the loading unit 210 may have a form capable of inserting the cartridge.

The shape of the loading unit 210 may vary depending on the type of the inspection medium, and may have various shapes.

The control unit 230 may determine whether the valid period of the inspection medium expires based on the first time information, and may control the analysis of the inspection object in accordance with the determination. In addition, under the control of the controller 230, the analyzer 240 can analyze the object to be inspected based on the second time information. The first time information and the second time information will be described in detail below through the first clock section 221 and the second clock section 222.

The first clock unit 221 may include first time information set as a reference time for determining whether the valid period of the inspection medium expires.

The reference time for determining whether the validity period of the inspection medium expires may mean the same time information as the time applied for setting the validity period of the inspection medium. For example, the reference time for determining whether the expiration date of the inspection medium expires may refer to time information set by the manufacturer of the inspection medium, and may include time information that can not be arbitrarily changed by the consumer or the user of the extracorporeal diagnostic device It can mean.

In addition, the first time information included in the first clock section 221 may not be set to any time other than the reference time. As described above, in the case where the extracorporeal diagnostic device 200 determines whether the expiration date of the inspection medium expires based on the time information that can be set at an arbitrary time, the intentional exploitation of the user can not be prevented. Therefore, the extracorporeal diagnostic device 200 according to some embodiments may not provide a method for the user to set the first time information to an arbitrary time, such as a user interface screen or a physical button.

In addition, the extracorporeal diagnostic device 200 according to some embodiments may initially set the first time information to a reference time through communication with the outside, or may periodically update the reference time. Therefore, the extracorporeal diagnostic device 200 according to some embodiments can eliminate an error between the reference time and the first time information by mechanical defects or the like. This will be described in more detail through the communication unit 370 of FIG.

The reference time may include time difference information. As described above, a plurality of extracorporeal diagnostic devices located in different regions and including different time differences can judge whether the validity period is expired for the same test medium differently. Accordingly, in the extracorporeal diagnostic device 200 according to some embodiments, in determining whether the expiration date of the inspection medium expires, the parallax information, which is a standard for setting the valid period of the inspection medium, and the parallax information of the area where the in- The above case can be prevented.

For example, the first time information may be set to a reference time based on Universal Time Coordinate (UTC). In addition, the validity period recorded on the inspection medium can also be set based on the negotiation world time. Accordingly, the control unit 230 determines whether the expiration date of the inspection medium expires in consideration of the difference between the parallax information, which is a criterion for setting the valid period of the inspection medium, and the parallax information of the first time information, . The first clock unit 221 will be described in more detail with reference to FIGS. 4 and 7. FIG.

The second clock unit 222 may include second time information that can be set at any time.

As described above, the user needs to set the time information of the extracorporeal diagnostic device 200 as arbitrary time information according to the necessity or purpose. For example, if the in vitro diagnostic device is used in one country and used in another country, or if it is produced in one country and used in another country, the user must set the time information of the external diagnostic device to the local time. Therefore, the extracorporeal diagnostic device 200 of the present invention includes the second clock unit 222 including the second time information, in addition to the first clock unit 221 including the first time information. In addition, unlike the first time information, the extracorporeal diagnostic device 200 may provide a user interface screen or a physical button that allows the user to modify the second time information to arbitrary time information.

The first clock section 221 may include a first RTC circuit, and the second clock section 222 may include a second RTC circuit. An RTC circuit is a widely used circuit for providing time information to a PC, a server, or an embedded system. However, the first and second clock units 221 and 222 may include any device capable of providing at least two mutually independent time information to the control unit 230, in addition to the RTC circuit.

When a predetermined trigger signal for notifying the start of the inspection is input, the control unit 230 drives the loading unit 210 to receive the inspection medium and control the analysis of the inspection target object to be started.

Also, the controller 230 may drive the sensor unit 225 to acquire the validity period of the inspection medium input through the loading unit 210 before starting the analysis of the inspection object.

The sensor unit 225 recognizes at least one of a bar code, a QR code, a text data, a data matrix, a recognition pattern, NFC, and RFID including information on at least one of the inspection object and the inspection medium, Can be obtained.

Specifically, the sensor unit 225 recognizes a bar code, a quick response code (QR) code, a text data, a data matrix, or a recognition pattern attached to the surface of the inspection medium, Radio Frequency Identification) to obtain the validity period of the inspection medium.

In addition, the sensor unit 225 can acquire information of at least one of the inspection object and the inspection medium by the same method. For example, the sensor unit 225 can recognize the barcode and the QR code attached to the surface of the inspection medium and obtain the physical condition such as the date of birth, race, height, and weight for the subject of the inspection target, And the like can be obtained.

The control unit 230 determines whether the validity period of the inspection medium expires based on the first time information. Specifically, the controller 230 may compare the first time information with the valid period of the inspection medium, and may determine that the valid period of the inspection medium has expired when the first time information has exceeded the valid period of the inspection medium.

In addition, under the control of the controller 230, the analyzer 240 can analyze the object to be inspected based on the second time information. The analyzer 240 may analyze an object to be examined such as blood, and may generate an analysis result that can determine whether or not a patient is infected with a predetermined disease.

Specifically, when the valid period of the inspection medium has not expired as a result of the control unit 230 determining whether or not the valid period of the inspection medium expires based on the first time information, the analyzing unit 240 determines, based on the second time information, The object to be inspected can be analyzed.

The analyzer 240 may not analyze the inspection object when the valid period of the inspection medium has expired as a result of the control unit 230 determining whether the valid period of the inspection medium expires based on the first time information. When the analyzing unit 240 analyzes the inspection object under the control of the controller 230, the time information used for the analysis and the time information recorded in the analysis result may be the second time information.

Specifically, the user interface unit 350 of FIG. 3 receives an input for changing the second time information 420a, and the control units 230 and 330, according to the received input, The time information 420a is changed from 2014.07.16 19:30 to the time information 420b 2014.05.16 11:30 in FIG. 4 (b).

The trigger buttons 440a and 440b can generate a predetermined trigger signal for notifying the start of inspection of the inspection object. For example, when the user interface unit 350 receives a user input for pressing the trigger buttons 440a and 440b, the control units 230 and 330 drive the loading units 210 and 310 to receive the inspection medium. Also, the sensor units 225 and 325 acquire the valid period of the input inspection medium. The control units 230 and 330 control the analyzers 240 and 340 according to whether the valid period of the inspection medium expires.

5 is a view for explaining an inspection medium according to some embodiments.

When the examination medium includes the blood test disc 500, the blood test disc 500 may be configured as shown in FIG.

Referring to FIG. 5, the blood collected from the patient is injected into the blood test disk 500 through the injection port 510 of the test medium. The injected blood is spread to at least one strip 521, 522, 523 contained in the blood test disc 500.

In addition, the blood test disc 500, which is an inspection medium, may include identification information 540, which is information capable of identifying the inspection medium. The identification information 540 may be formed of a QR code as shown in FIG. 5 and may be attached to the front surface of the blood test disc 500.

The analyzer 240 analyzes the inspection object included in the inspection medium. For example, the analysis unit 240 may perform blood blood analysis using the blood present in the strips 521, 522, and 523 included in the blood test disk 500 that is an examination medium.

The analyzer 240 may perform a predetermined test on the test object. The analysis unit 240 may perform a predetermined test to determine whether the patient is infected with a predetermined disease based on the identification information 540. [ In addition, the analyzer 240 may perform a predetermined test to determine a predetermined disease based on the setting of the user or the initial setting of the extracorporeal diagnostic device 200, 300 itself.

For example, the analyzer 240 can perform the TnI test using the blood to be inspected. Here, the TnI test is a cardiac marker test used to diagnose acute coronary syndrome (ACS), including acute myocardial infarct (AMI). TnI (troponin I) testing is required as a cardiac marker test if an emergency patient is involved in myocardial infarction. TnI is an index of myocardial damage, which is present in the blood when myocardial tissue is damaged.

The identification information 540 of the inspection medium may include information about at least one of the inspection object and the inspection medium. In addition, the identification information 540 of the inspection medium may include the validity period information 541 of the inspection medium. For example, the validity period of the blood test disc 500 shown in FIG. 5 is 2014.06.12 11:30 UTC (+00: 00).

Further, the sensor units 225 and 325 can recognize the identification information 540, which is the QR code, and obtain the valid period of the inspection medium. In addition, the sensor units 225 and 325 may recognize the identification information 540, which is a QR code, to acquire physical conditions such as date of birth, race, height, weight and the like with respect to the testee of the test subject, Manufacturing date, and the like.

6 is a view for explaining a notification signal output from the extracorporeal diagnostic device according to some embodiments. 6 (a) shows a user interface screen 600a indicating that the validity period of the inspection medium is being judged, FIG. 6 (b) shows a user interface Screen 600b.

Specifically, the user interface screen 600a including the message 610a indicating that the validity period is being judged is updated from the time when the trigger signal indicating the start of the test is input to the end of the validity period of the test medium based on the first time information Or may be displayed by the display unit 361 until it is judged whether or not it is judged.

When the effective period of the inspection medium has expired, the control units 230 and 330 generate a notification signal indicating the expiration of the valid period, and the output unit 360 outputs the notification signal.

The notification signal may include a user display screen 620b, such as a message or pop-up window indicating the expiration of the validity period. Also, the display unit 361 included in the output unit 360 can display the user interface screen 620b, which is a notification signal. In addition, the notification signal may include a visual signal such as an LED or an audible signal such as a beep.

For example, the first time information 410a, 410b in Fig. 4: 2014.07.16. Valid period information 541 of the blood test disc 500 of FIG. 5 based on 10:30 UTC (+00: 00): 2014. 06.12. 11:30 UTC (+00: 00) has expired. Therefore, the control units 230 and 330 can generate the notification signal indicating the expiration of the valid period irrespective of the second time information 420a and 420b.

FIG. 7 is a diagram for explaining an operation in which the extracorporeal diagnostic device according to some embodiments determines the validity period of the inspection medium 700. 7 is a diagram for explaining an operation of determining whether the expiration date diagnostic unit located in different regions expires the expiration date 710 of the same inspection medium 700. FIG.

The user 720a located in Hawaii can set the second time information 740a of the extracorporeal diagnostic device to the local time (UTC (-10: 00)). The user 720b located in Osaka can set the second time information 740b of the extracorporeal diagnostic device to the local time (UTC (+09: 00)).

With reference to 740a second time information, validity period 710 of inspection medium 700 has expired. However, with reference to 740b second time information, validity period 710 of inspection medium 700 has not expired. Therefore, if the second time information 740a, 740b set as the local time is used as a reference, the validity period 710 of the inspection medium 700 can be judged differently according to the position of the extracorporeal diagnostic device.

The user may set the second time information 740a and 740b to an arbitrary time that is slower than the valid period 710 of the inspection medium 700 for the purpose of exploiting the inspection medium 700 for which the valid period 710 has expired . If the extracorporeal diagnostic device determines whether the expiration date of the inspection medium expires based on the second time information 740a, 740b, there is no way to prevent such exploitation on the extracorporeal diagnostic device.

Accordingly, the extracorporeal diagnostic apparatus according to the present invention determines whether the expiration date of the inspection medium expires based on the first time information 730a, 730b set as the reference time to determine whether the expiration date 710 has expired

Therefore, irrespective of the second time information 740a and 740b, both the extracorporeal diagnostic device located in Hawaii and the extracorporeal diagnostic device located in Osaka generate a notification signal indicating the expiration of validity period 710 for the same inspection medium 700. [ For example, the notification signal may include a user interface screen 750a, 750b indicating the expiration of validity period 710. [

In addition, both the extracorporeal diagnostic unit located in Hawaii and the analysis units 240 and 340 of the extracorporeal diagnostic unit located in Osaka may expire the validity period 710 of the inspection medium 700 and may not analyze the inspected object.

8 is a diagram for explaining an operation in which the extracorporeal diagnostic device according to some embodiments resets the first time information.

The first clock units 221 and 222 and the second clock units 222 and 322 can be supplied power from independent power sources to other components of the extracorporeal diagnostic device in order to continuously count the time. Also, the power supply unit of the first clock units 221 and 321 and the power supply units of the second clock units 222 and 322 may be independent of each other. For example, the power supply may include a battery.

If the power of the second clock unit 802 is turned off and then re-supplied, the user can set the second time information to an arbitrary time using a user interface screen or the like.

However, since the first time information must be set as the reference time, when the first clock unit 801 is powered off and then re-supplied, the extracorporeal diagnostic apparatuses 200 and 300 themselves can set the first time information Need to be reset.

For example, the control unit 800 can obtain the power cut-off time 821, which is the first time information when the first clock unit 801 is powered off. The control unit 800 controls the second clock unit 802 to output the time difference 852 from the power cutoff time 821 until the power of the first RTC circuit is recharged to reset the first time information T4, And can reset the first time information 841 based on the power-off time 821 and the time difference 852. [

Specifically, when the in vitro diagnostic device is located in Korea, the second time information may be set to the local time (UTC (+09: 00)). For example, at time T1 810, the first time information 811 of the first clock unit 801 is 2014.03.03. 02:30 UTC (+00: 00), and the second time information 812 of the second clock section 802 is set to 2014.03.03. 11:30.

The power of the first clock unit 801 is cut off at the T2 point of time 820 after 30 minutes from the T1 point of view 810. [ The first time information 851 is supplied from the time point T1 810 at which the power of the first clock unit 801 is cut off to the time point T4 at which the control unit 800 resets the first time information, May not coincide with the reference time.

The control unit 800 may store the power off time 821 as the first time information of the first clock unit 801 in the storage unit 380 as the third time information 823 at the time T1 810 .

Thereafter, the control unit 800 can acquire the time difference 852 from the time T2 when the power of the first RTC circuit is turned off to the time T4 when the first time information is reset, based on the second clock unit 802 . For example, the control unit 800 may acquire the counting number of the second clock unit 802 during T2 to T4, or may calculate the second time information 822 at the time T2 and the second time information 832 at the time T4 The time difference 852 from the T2 time point 820 to the T4 time point 840 can be obtained by calculating the difference.

After power is supplied again to the first clock unit 801 at the T3 time point 830, the control unit 800 outputs the third time information 823, 03.03.03. 03:00 UTC 00: 00), the first time information 841 can be reset to the reference time 2014. 03. 03. 06:00 UTC (00:00) by adding a time difference 852 (3 hours).

8 shows a state in which the control unit 800 resets the first time information 841 of the first clock unit 801 from the T3 time point 830 at which power is supplied again to the first clock unit 801 T4 time (840) is about 1 minute. However, depending on the performance of the extracorporeal diagnostic devices 200 and 300, T3 and T4 may be at the same time.
