Detailed Description
The present invention will be described in further detail with reference to the following detailed description and accompanying drawings. In some instances, certain operations related to the present application have not been shown or described in detail in order to avoid obscuring the core of the present application from excessive description, and it is not necessary for those skilled in the art to describe these operations in detail, so that they may be fully understood from the description in the specification and the general knowledge in the art.
Furthermore, the features, operations, or characteristics described in the specification may be combined in any suitable manner to form various embodiments. Also, the various steps or actions in the method descriptions may be transposed or transposed in order, as will be apparent to one of ordinary skill in the art. The terms "connected" and "coupled" when used herein, unless otherwise indicated, include both direct and indirect connections (couplings).
In the embodiment of the invention, the times that the in-vitro diagnostic apparatus can change the reagent are limited by adopting the times that the reagent can be loaded; when the reagent needs to be replaced, acquiring the reagent loadable times, loading the reagent when the reagent loadable times is more than 0 and subtracting 1 from the reagent loadable times, and forbidding the reagent loading when the reagent loadable times is equal to 0.
The embodiment of the invention provides an in-vitro diagnostic apparatus, which has a schematic structural diagram shown in fig. 1, and as shown in fig. 1, the in-vitro diagnostic apparatus comprises an information input device 11, a main control unit 12 and a human-computer interaction device 13. The information input device 11 is connected with the main control unit 12, and when the reagent needs to be replaced, the information input device 11 acquires the reagent information and outputs the reagent information to the main control unit 12; the main control unit 12 is configured to determine whether the reagent to be loaded is an effective reagent according to the reagent information acquired by the information entry device 11, and acquire a reagent loadable frequency, load the reagent and subtract 1 from the reagent loadable frequency when the reagent to be loaded is an effective reagent and the reagent loadable frequency is greater than 0, and prohibit reagent loading when the reagent loadable frequency is equal to 0; the human-computer interaction device 13 is connected to the main control unit 12, and is configured to receive input information of a user and display information such as reagent information, setting information, and a sample detection result. In a specific implementation, the human-computer interaction device 13 is further configured to display the number of times that the in vitro diagnostic apparatus can be loaded with the reagent currently, so as to facilitate the user to view the number of times.
The reagent information acquired by the information entry device 11 may include information such as reagent type information, reagent expiration date, reagent content, and the like, and after the main control unit 12 receives the reagent information, if it is determined that the reagent type matches the in vitro diagnostic apparatus, the reagent to be loaded is not expired, and the remaining amount of the reagent is not 0, it may be determined that the reagent to be loaded is a valid reagent, otherwise, the reagent to be loaded is considered to be invalid. For example, the in vitro diagnostic apparatus is a blood cell analyzer, which consumes a hemolytic agent when performing a test of a blood sample, and if reagent type information in the reagent information indicates a hemolytic agent, the reagent type information is matched with the in vitro diagnostic apparatus.
Since the number of times that the reagent of the in vitro diagnostic apparatus can be loaded defines the number of times that the reagent can be loaded, when the number is used up, the in vitro diagnostic apparatus cannot be loaded with the reagent, and at this time, the number of times that the reagent can be loaded needs to be recharged. In the embodiment of the invention, the number of times that the reagent of the in vitro diagnostic apparatus can be loaded can be recharged by the reagent source information, the reagent source information at least comprises the reagent number N (N is an integer greater than or equal to 1), and the reagent number N is the number of the reagent purchased by the user. Specifically, the information input device 11 may obtain reagent source information, and output the reagent source information to the main control unit 12, at this time, the main control unit 12 verifies the reagent source information, and when the verification passes, the number of times that the reagent can be loaded is increased by N; if the main control unit 12 determines that the reagent source information is already acquired information or determines that the reagent source information is not verified, the main control unit 12 may output a prompt message indicating that the acquisition of the reagent source information fails to be displayed to the human-computer interaction device 13. In order to verify the reagent source information, an authentication code may be set in the reagent source information, when receiving the reagent source information input by the information input device 11, the main control unit 12 determines whether the authentication code in the reagent source information matches the source password of the in-vitro diagnostic apparatus, and when the authentication code matches the source password of the in-vitro diagnostic apparatus, the main control unit 12 passes the verification, and at this time, the main control unit 12 increases the number of times that the current reagent of the in-vitro diagnostic apparatus can be loaded by N. The authentication code may be a user-defined password, a serial number of the in vitro diagnostic apparatus, or a preset unique identifier. In practical applications, the reagent source information may also include reagent series and reagent type.
Based on this, before the in vitro diagnostic apparatus is sold, the reagent loadable number of the in vitro diagnostic apparatus may be set to a default value of 0, at which time the in vitro diagnostic apparatus cannot be loaded with the reagent. When a seller sells the in-vitro diagnostic apparatus to a user, the seller simultaneously provides the user with a matched reagent, for example, N bottles of reagents are provided for the user, at this time, the seller can set the number of the reagents to be N through tools such as a reagent management device and the like, set an authentication code, then generate reagent source information, and finally provide the reagent source information and the reagent together to the user, so that the user can recharge the reagent loadable times of the in-vitro diagnostic apparatus through the reagent source information, after recharging, the reagent loadable times is N, thereby limiting that the in-vitro diagnostic apparatus can only load the N bottles of reagents, namely limiting that the in-vitro diagnostic apparatus can only load the N bottles of reagents. The reagent management device may be, for example, management software for generating reagent source information. When the N bottles of reagents are used up, the reagent loadable times of the in-vitro diagnostic apparatus is reduced to 0, at the moment, the reagent cannot be loaded, and the reagent loadable times need to be recharged again; because the in vitro diagnostic apparatus limits that the authentication code in the reagent source information needs to be matched with the source password of the in vitro diagnostic apparatus, a user can only purchase a reagent from a seller of the in vitro diagnostic apparatus and obtain new reagent source information so as to recharge the loadable times of the reagent. Therefore, the reagent is bound with the in-vitro diagnostic apparatus, so that the reagent used by the in-vitro diagnostic apparatus is ensured to be a matched reagent provided by the same seller, and the problem that the detection effect of the instrument and the sample measurement accuracy are influenced due to the phenomenon of non-matching between the instrument and the reagent in the prior art is solved.
In practical applications, the information input device 11 may be a barcode scanner, a radio frequency identification card reader, etc., the reagent information may be reagent barcode information on the reagent bottle, and the reagent source information may be in the form of a barcode, an authentication code, a serial code, etc., and the user may input the reagent information or the reagent source information to the main control unit 12 through the human-computer interaction device 13 or the information input device 11.
In the above embodiment, the source code of the in-vitro diagnostic apparatus may be implemented by importing a key file into the in-vitro diagnostic apparatus, and the key file may be generated by the reagent management apparatus. Specifically, a first password may be set in the key file, and then the key file is imported into the in-vitro diagnostic apparatus, at this time, the main control unit 12 may verify the key file, and when the verification passes, the first password in the key file is used as the source password of the in-vitro diagnostic apparatus, and when the verification fails, the prompt information indicating that the import of the key file fails may be output to the human-computer interaction device 13 for display. In order to prevent other people from changing the source password of the in-vitro diagnostic apparatus by importing the key file, a second password can be set in the key file; at this time, when receiving the key file imported from the outside, the main control unit 12 first determines whether the second password in the key file matches the current source password of the in vitro diagnostic apparatus, and if so, changes the current source password of the in vitro diagnostic apparatus into the first password in the key file. The first password may be a user-defined password, a serial number of the in vitro diagnostic apparatus, or a preset unique identifier.
In practical application, the reagent source information and the key file can be generated in an encrypted manner, so that the reagent source information and the key file are transmitted to the in-vitro diagnostic apparatus in an encrypted form, and the relevant information in the reagent source information and the key file can be prevented from being leaked in the setting or transmission process.
In practical application, the in vitro diagnostic apparatus may also perform reagent loading according to the original reagent loading process, and if the original reagent loading process is to be started, the in vitro diagnostic apparatus may be implemented by inputting a third password to the in vitro diagnostic apparatus. Specifically, when the main control unit 12 receives the third password detected by the human-computer interaction device 13, the main control unit 12 determines whether the third password matches the serial number of the in-vitro diagnostic apparatus, determines whether the reagent information acquired by the information input device 11 is valid when the third password matches the serial number of the in-vitro diagnostic apparatus, loads the reagent when the reagent information is valid, and outputs the prompt information of the reagent loading failure to the human-computer interaction device 13 to display when the reagent information is invalid.
Based on the in vitro diagnostic apparatus of the above embodiment, the embodiment of the present invention further provides a reagent management apparatus, so that the reagent management apparatus generates the required reagent source information and the key file.
Fig. 2 is a schematic structural diagram of a reagent management apparatus according to an embodiment of the present invention, and as shown in fig. 2, the reagent management apparatus includes a display unit 21, an obtaining unit 22, and a reagent source information generating unit 23.

The source password of the in-vitro diagnostic instrument is set by a seller, and the seller can set the second password as the current source password of the in-vitro diagnostic instrument when generating the key file, so that when the key file is imported into the in-vitro diagnostic instrument, the source password of the in-vitro diagnostic instrument can be changed only when the second password is matched with the current source password of the in-vitro diagnostic instrument through consistency comparison, thereby limiting that the source password of the in-vitro diagnostic instrument can only be changed by the seller of the in-vitro diagnostic instrument, and further preventing other people from randomly changing the source password of the in-vitro diagnostic instrument.
Fig. 3 is a schematic diagram of a key file setting interface, as shown in fig. 3, where "the first password" is a first password setting menu, and "the second password" is a second password setting menu. The seller can set corresponding passwords in each setting menu, and can further generate corresponding key files after clicking the 'confirm' button; the user can also click a cancel button to cancel the setting.
The reagent source information configuration interface also comprises an authentication code configuration menu, a reagent series configuration menu, a reagent type configuration menu and a printing button; at this time, the obtaining unit 22 is configured to obtain, in addition to the reagent number N set in the reagent loadable number setting menu, the authentication code, the reagent series, and the reagent type respectively selected from the authentication code configuration menu, the reagent series configuration menu, and the reagent type configuration menu, generate a print command when obtaining a click operation on a print button on the reagent source information configuration interface, and send the print command to the reagent source information generating unit 23; the reagent source information generating unit 23 is specifically configured to, when receiving the print command sent by the obtaining unit 22, perform encryption processing on the reagent number N, the authentication code, the reagent series, and the reagent type obtained by the obtaining unit 22, and generate reagent source information; the authentication code is used for matching with the current source password of the in-vitro diagnostic apparatus, so that the number of times that the current reagent of the in-vitro diagnostic apparatus can be loaded is increased by N when the authentication code is matched with the current source password of the in-vitro diagnostic apparatus. Thus, by setting the authentication code, the reagent loadable times can only be provided by the vendor of the in vitro diagnostic apparatus.

If the operation needs to be cancelled, the cancel button can be clicked to cancel the operation of finding back the source password.
In practical application, the reagent management device can be in close range communication with an in vitro diagnostic apparatus in the modes of USB, WIFI, Bluetooth and the like, and can also be in remote communication with the in vitro diagnostic apparatus.
Based on the in vitro diagnostic apparatus and the reagent management device of the above embodiments, an embodiment of the present invention further provides a method for replacing a reagent, a flowchart of which can be seen in fig. 6, and the method may include the following steps:
step 101: reagent information is obtained.
When the in vitro diagnostic apparatus needs to replace the reagent, the reagent information is acquired through the information input device 11 or the human-computer interaction device 13.
Step 102: and judging whether the reagent is an effective reagent or not, and obtaining the number of times that the reagent can be loaded.
After the in-vitro diagnostic apparatus obtains the reagent information, whether the reagent to be loaded is the effective reagent is judged according to the reagent information, and the current reagent loading times of the in-vitro diagnostic apparatus is obtained. When the reagent to be loaded is a valid reagent, step 103 is performed; otherwise step 105 is performed.
Step 103: and judging whether the reagent loadable times are more than 0.
Executing step 104 when the in vitro diagnostic apparatus judges that the reagent loadable frequency is more than 0; when the number of reagent loadable times is equal to 0, step 105 is performed.
Step 104: load reagent and reduce the number of reagent loadable times by 1.
Step 105: the loading of the reagent is prohibited.
In the method for replacing a reagent provided by this embodiment, when the reagent needs to be replaced, whether the remaining number of times that the reagent can be loaded currently remains is determined by querying the current number of times that the in vitro diagnostic apparatus can be loaded, and when the number of times that the reagent can be loaded is 0, the reagent is prohibited from being loaded, that is, the number of times that the in vitro diagnostic apparatus can be loaded with the reagent is limited by the number of times that the reagent can be loaded. Therefore, when the seller of the in-vitro diagnostic apparatus provides N bottles of reagents for a user, the reagent can be loaded for times to limit the in-vitro diagnostic apparatus to only load the N bottles of reagents, so that the reagents are bound with the in-vitro diagnostic apparatus, the phenomenon that the reagents are not matched with the in-vitro diagnostic apparatus due to the fact that the seller of the in-vitro diagnostic apparatus is inconsistent with the seller of the reagents is avoided, and further the influence on the detection effect of the in-vitro diagnostic apparatus and the accuracy of sample measurement due to the fact that the reagents are not matched with each other is avoided.
In the above embodiments, the information input device 11 may be a barcode scanner, a radio frequency identification card reader, etc., the reagent information may be a reagent barcode on the reagent bottle, and the reagent source information may be in the form of a barcode, an authentication code, a serial code, etc. The present invention will be further illustrated below by taking the information recording device 11 as a barcode, the reagent information as a reagent barcode, and the reagent source information as a barcode (referred to as an auxiliary barcode here for the purpose of distinguishing from the reagent barcode).
Fig. 7 is a flowchart of a specific method for replacing a reagent according to an embodiment of the present invention, in which a reagent management apparatus is provided by an external diagnostic apparatus manufacturer to an external diagnostic apparatus seller, and the reagent management apparatus is a tool for managing a reagent, and can be used to set a source password, generate a key file, generate reagent source information, and the like of the external diagnostic apparatus, for example, reagent management software, which can be run on a terminal such as a laptop, a desktop computer, a PAD, and the like; as shown in fig. 7, the method may include the steps of:
step 201: a key file is generated.
Before selling the in-vitro diagnostic apparatus, the seller of the in-vitro diagnostic apparatus needs to start the anti-channel conflict function of the in-vitro diagnostic apparatus by importing the key file into the in-vitro diagnostic apparatus, so that the required key file needs to be generated firstly. At this time, the seller runs the reagent management software on the terminal, and selects the key file setting interface according to the interface prompt of the software, at this time, the display unit 21 displays the key file setting interface, the seller sets a first password and a second password on the interface, and after the determination, the reagent management software can generate the key file. Preferably, after the determination, the reagent management software encrypts the set first password and the second password to generate the key file.
For example, FIG. 8 illustrates a main interface of the reagent management software when running, which may include a menu of choices for auxiliary barcode settings, key file management, and retrieval of passwords. When the key file needs to be generated, a key file management option can be selected, and at this time, relevant information of key file configuration is displayed on an interface, for example, the information can include a key file list and buttons for creating, deleting, generating and the like; a seller can find a corresponding in-vitro diagnostic apparatus in a key file list through an in-vitro diagnostic apparatus identification code, a key file setting interface shown in fig. 3 can be popped up after the in-vitro diagnostic apparatus is clicked, and then a first password and a second password can be respectively input in a setting menu of a first password and a second password, wherein the first password is a newly set password and is used for setting a new source password for the in-vitro diagnostic apparatus, the second password is an old password and is a current source password of the selected in-vitro diagnostic apparatus, and if the source password is not set for the in-vitro diagnostic apparatus, the setting menu of the second password can be not input; the information of the key file is determined after clicking the 'determination' button, and at this time, the corresponding key file can be generated by clicking the 'generation' button on the key file management interface. If the key file list does not have the desired in vitro diagnostic instrument, the seller can click the "new" button to add the identification number of the desired in vitro diagnostic instrument. If the seller forgets the current source password of the selected in-vitro diagnostic apparatus, the seller can select the retrieval password option on the interface to retrieve the source password in the manner shown in fig. 5.
Step 202: an auxiliary barcode is generated.
The seller selects an auxiliary bar code configuration interface (namely a reagent source information configuration interface) on the reagent management software according to the interface prompt, sets an authentication code, a reagent series and a reagent type in an authentication code configuration menu, a reagent series configuration menu and a reagent type configuration menu respectively, sets the number of reagents in a reagent loadable times setting menu, and then clicks a printing button, and the reagent management software encrypts and prints the information into an auxiliary bar code. Wherein, the reagent series and the reagent type can be input by a seller or selected from a provided pull-down menu; the set authentication code is the same as a first password input by a seller on a key file setting interface; the number of reagents inputted in the reagent loadable times setting menu is the number of reagents sold to the user. Thus, when a seller sells N bottles of reagents to a user, the user is provided with an auxiliary bar code in which the authentication code matches the first password of the key file and the number of the reagents is N.
For example, a seller sells 5 bottles of reagents to a user, at this time, the seller may select an auxiliary barcode setting option on the main interface shown in fig. 8, and switch the interface to the configuration interface shown in fig. 4, at this time, the seller selects a reagent series and a reagent type on the interface according to the reagents sold to the user, sets an authentication code to be the same as the first password of the key file in the authentication code configuration menu, sets the number of the reagents to 5, clicks a print button to generate a desired auxiliary barcode, and then provides the auxiliary barcode together with the reagents to the user. In practical application, the authentication code configuration menu may be designed to be a pull-down menu in which the authentication code is manually input, or the identification code of the in vitro diagnostic apparatus is used as an option, and a seller may select the identification code in the pull-down menu, which is the same as the identification code of the in vitro diagnostic apparatus when the key file is generated, and at this time, it is equivalent to use the first password in the key file as the authentication code.
In practical application, the first password and the authentication code may be a custom password, or a serial number of the in vitro diagnostic apparatus, or a preset unique identifier.
Step 203: and importing the key file.
Before selling the in-vitro diagnostic apparatus, the seller introduces the key file generated in step 201 into the in-vitro diagnostic apparatus, so that the anti-channel conflict function of the in-vitro diagnostic apparatus is started, and at this time, the reagent loadable frequency of the in-vitro diagnostic apparatus is 0 as a default value. And if the first password set in the key file is S, the source password of the in-vitro diagnostic apparatus is S.
In this process, the source password of the in-vitro diagnostic apparatus is set by importing the key file to the in-vitro diagnostic apparatus, and thus, a vendor may change the source password of the in-vitro diagnostic apparatus by importing a new key file to the in-vitro diagnostic apparatus. In order to prevent other people from changing the source password of the in-vitro diagnostic apparatus by importing a new key file, in this embodiment, a second password is set in the key file, so that when the new key file is imported into the in-vitro diagnostic apparatus, matching authentication needs to be performed on the second password, and the source password of the in-vitro diagnostic apparatus can be successfully changed only when the authentication passes. Specifically, referring to fig. 9, a flowchart of a method for importing a key file may include the following steps 2031 to 2034.
Step 2031: the new key file is parsed.
Since the key file is an encrypted file, when a new key file is imported into the in-vitro diagnostic apparatus, the main control unit 12 of the in-vitro diagnostic apparatus needs to analyze the new key file to obtain the first password and the second password therein.
Step 2032: and judging whether the second passwords are matched.
After the main control unit 12 obtains the second password, the second password is compared with the current source password of the in vitro diagnostic apparatus, if the second password is consistent with the current source password of the in vitro diagnostic apparatus, the second password is considered to be matched with the current source password of the in vitro diagnostic apparatus, and step 2033 is executed; otherwise, step 2034 is performed.
Step 2033: the source password is changed.
When the main control unit 12 determines that the second password in the new key file matches the current source password of the in vitro diagnostic apparatus, the new key file is successfully imported, and at this time, the main control unit 12 changes the current source password of the in vitro diagnostic apparatus into the first password in the new key file.
Step 2034: and prompting that the new key file is failed to be imported.
When the main control unit 12 determines that the second password in the new key file is inconsistent with the current source password of the in vitro diagnostic apparatus, it refuses to import the new key file, and may display a prompt message indicating that the import of the new key file fails on the display interface of the human-computer interaction device 13, at this time, the source password of the in vitro diagnostic apparatus remains unchanged.
For example, the key file currently imported by the in-vitro diagnostic apparatus is a, the first password set by the seller in a is S1, and the source password of the in-vitro diagnostic apparatus is S1. When a seller wants to change the source password of the in-vitro diagnostic apparatus, a new key file B may be generated first, the first password and the second password of the key file B are set to be S2 and S1 respectively in the process of generating the key file B, and then the key file B is imported into the in-vitro diagnostic apparatus; at this time, the second password in the key file B is the same as the current source password of the in-vitro diagnostic apparatus, and the in-vitro diagnostic apparatus will allow the import of the key file B and successfully change its source password to S2. The second password in the B is the current source password of the in-vitro diagnostic apparatus, and the seller knows the password, but cannot know the password for other people, so that when other people want to change the source password of the in-vitro diagnostic apparatus by importing a new key file, the matching relationship between the second password in the new key file and the current source password of the in-vitro diagnostic apparatus cannot be ensured, and thus, the source password of the in-vitro diagnostic apparatus can be effectively prevented from being changed by other people by performing matching authentication on the second password on the newly imported key file.
Step 204: the reagent of the in vitro diagnostic instrument can be loaded with value for times.
The reagent loadable frequency of the in vitro diagnostic apparatus purchased by the user from the seller defaults to 0, and the reagent loading is prohibited at this time. Before reagent loading, the reagent loadable times need to be recharged, taking the number of the reagent purchased by the user as N as an example, a specific recharging process is shown in fig. 10, and may include the following steps 2041 to 2046:
step 2041: the auxiliary barcode is scanned.
The user scans the auxiliary bar code provided by the seller by using the bar code scanner to obtain the bar code information of the auxiliary bar code.
Step 2042: and judging whether the auxiliary bar code is the read bar code.
The main control unit 12 of the in vitro diagnostic apparatus judges whether the auxiliary bar code is a read bar code according to the acquired bar code information, if the auxiliary bar code is an unread bar code, the step 2043 to 2045 is executed; if the barcode is a repeated barcode that has already been read, step 2046 is performed.
Step 2043: the auxiliary bar code is parsed.
The main control unit 12 analyzes the acquired information of the auxiliary barcode to obtain the authentication code and the number N of the reagents therein.
Step 2044: and judging whether the authentication codes are matched.
After obtaining the authentication code, the main control unit 12 determines whether the authentication code matches the current source password of the in vitro diagnostic apparatus. If so, go to step 2045; if not, go to step 2046.
Step 2045: the number of times the reagent can be loaded is increased by N.
When the authentication code in the auxiliary bar code is matched with the current source password of the in-vitro diagnostic apparatus, the auxiliary bar code can be considered to be provided by the seller of the in-vitro diagnostic apparatus, at the moment, the reagent loadable times of the in-vitro diagnostic apparatus is allowed to be charged, and the reagent loadable times is increased by N. Thus, the number of times the reagent of the in vitro diagnostic apparatus can be loaded is changed from the initial 0 to N.
Step 2046: prompting the failure of the scan.
When the auxiliary bar code is a read repeated bar code or the authentication code in the auxiliary bar code is not matched with the current source code of the in vitro diagnostic apparatus, the human-computer interaction device 13 can output prompt information of scanning failure (namely failure in acquiring reagent source information), and at the moment, the reagent loading times of the in vitro diagnostic apparatus are kept unchanged.
Step 205: the reagent barcode is scanned.
When reagent is loaded, a reagent barcode on a reagent vial to be loaded with reagent is scanned by a barcode scanner.
Step 206: and judging whether the reagent bar code is effective or not.
After scanning the reagent bar code of the reagent to be loaded through the bar code scanner, the main control unit 12 analyzes the reagent bar code to obtain reagent information, and then judges whether the reagent type of the reagent to be loaded is matched with the in vitro diagnostic apparatus (i.e. whether the reagent is a reagent suitable for the in vitro diagnostic apparatus), whether the reagent is overdue, whether the residual amount of the reagent is 0, when the reagent type is matched with the in vitro diagnostic apparatus, the reagent is not overdue, and the residual amount of the reagent is not 0, the reagent bar code is considered to be valid, otherwise, the reagent bar code is considered to be invalid. If the main control unit 12 determines that the reagent barcode is valid, then step 207-step 211 are executed; if the main control unit 12 determines that the reagent barcode is invalid, step 211 is executed.
Step 207: and judging whether the reagent bar code is a repeated bar code.
And when the reagent bar code is effective, judging whether the reagent bar code is a repeated bar code, namely judging whether the reagent bar code is a read bar code. If yes, go to step 208; if not, step 209 to step 211 are executed.
Step 208: indicating successful reagent loading.
When the main control unit 12 judges that the reagent bar code is the read reagent bar code, the human-computer interaction device 13 can prompt that the reagent is loaded successfully, at this time, the in vitro diagnostic apparatus can load the reagent, but the current reagent loading times of the in vitro diagnostic apparatus are kept unchanged.
Step 209: and judging whether the reagent loadable times are more than 0.
When the main control unit 12 determines that the reagent barcode is an unread reagent barcode, it further determines whether the current reagent loadable frequency of the in vitro diagnostic apparatus is greater than 0. If the number of times that the current reagent of the in vitro diagnostic apparatus can be loaded is greater than 0, executing step 210; if the number of times that the in vitro diagnostic apparatus can be loaded with the current reagent is equal to 0, step 211 is executed.
Step 210: load reagent and reduce the number of reagent loadable times by 1.
When the main control unit 12 judges that the number of times that the reagent of the in-vitro diagnostic apparatus can be loaded is greater than 0, the in-vitro diagnostic apparatus is allowed to load the reagent, at this time, the in-vitro diagnostic apparatus successfully loads the reagent, the prompt information that the reagent is successfully loaded can be displayed through the human-computer interaction device 13, and meanwhile, the main control unit 12 subtracts 1 from the number of times that the reagent of the in-vitro diagnostic apparatus can be currently loaded.
Step 211: indicating a reagent loading failure.
When the main control unit 12 judges that the number of times that the external diagnostic apparatus can load the current reagent is equal to 0, the number of times that the external diagnostic apparatus can load the reagent bar code is considered to be used up, at this time, the external diagnostic apparatus is not allowed to load the reagent, the prompt message of the loading failure of the reagent can be displayed through the human-computer interaction device 13, and at this time, the number of times that the reagent can be loaded is kept to be 0.
Thus, after the number of times that the reagent of the in-vitro diagnostic apparatus can be loaded is used up, if the user needs to replace the reagent of the in-vitro diagnostic apparatus, the user needs to purchase the reagent again from the seller of the in-vitro diagnostic apparatus, and the seller can generate the auxiliary barcode again according to the number of the reagent purchased by the user in step 202 and provide the auxiliary barcode to the user. At this time, the in-vitro diagnostic apparatus recharges the reagent loadable times according to the flow of step 204, and then, when the user changes the reagent, the in-vitro diagnostic apparatus loads the reagent according to the flow after step 205 as long as the user scans the reagent bar code of the reagent to be loaded.
In practical application, the number of times that the reagent of the in vitro diagnostic apparatus can be loaded currently can be displayed on the display interface of the human-computer interaction device 13, so that the user can conveniently view the number of times.
In the method for replacing the reagent provided by the embodiment, because the auxiliary bar code provided by the seller for the user limits the number of times that the in-vitro diagnostic apparatus can load the reagent to be the same as the number of the reagent sold to the user, when the user uses up the reagents, the current reagent loadable number of times of the in-vitro diagnostic apparatus is reduced to 0, at this time, the in-vitro diagnostic apparatus cannot load the reagent, and the reagent loadable number of times needs to be recharged; the external diagnostic apparatus limits the authentication code in the auxiliary bar code to be matched with the current source code of the external diagnostic apparatus, and the source code is set by a seller, so that a user can only buy a matched reagent from the seller of the external diagnostic apparatus, a unique binding relationship is established for the reagent and the external diagnostic apparatus, the reagent bought by the user is ensured to be the reagent matched with the external diagnostic apparatus, the influence on the detection effect and the sample measurement accuracy of the external diagnostic apparatus due to the phenomenon of mismatching between the reagent and the external diagnostic apparatus is avoided, and the detection effect and the sample measurement accuracy of the external diagnostic apparatus are ensured.
In practical applications, if a seller wants to turn off the anti-channel conflict function of the in-vitro diagnostic apparatus, a third password may be input to the in-vitro diagnostic apparatus through the human-computer interaction device 13, where the third password is provided by a manufacturer of the in-vitro diagnostic apparatus, and the third password needs to be bound with the in-vitro diagnostic apparatus, for example, with a serial number of the in-vitro diagnostic apparatus. Based on this, fig. 11 shows another method of replacing a reagent, which may comprise the steps of:
step 301: the reagent barcode is scanned.
Step 302: and judging whether the reagent bar code is effective or not.
The specific process of the main control unit 12 determining whether the reagent barcode is valid is the same as the step 206, and if the reagent barcode is determined to be valid, the step 303 is executed; if the reagent barcode is determined to be invalid, go to step 306.
Step 303: and judging whether the anti-channel conflict function is started or not.
If the main control unit 12 detects that the third password is input to the external diagnostic apparatus of the selling party and the third password is matched with the serial number of the external diagnostic apparatus, it is determined that the anti-channel conflict function is closed, and at this time, step 304 is executed; if it is detected that the key file is imported to the in-vitro diagnostic apparatus by the seller, and the third password is not input or the input third password is incorrect (not matched with the serial number of the in-vitro diagnostic apparatus), it is determined that the anti-channel conflict function is opened, and then step 305 is executed.
Step 304: and (4) loading a reagent.
When the reagent bar code is effective and the anti-channel conflict function is not started, the in vitro diagnostic apparatus successfully loads the reagent, and at the moment, prompt information of successful reagent loading can be displayed on the display interface of the human-computer interaction device 13.
Step 305: and determining whether to load the reagent according to the anti-channel conflict function.
When the reagent bar code is valid and the anti-channel conflict function is turned on, the in vitro diagnostic apparatus determines whether to load the reagent according to the processes of the steps 207 to 211.
Step 306: indicating a reagent loading failure.
When the main control unit 12 determines that the reagent bar code is invalid, the in vitro diagnostic apparatus does not load the reagent, and the reagent fails to be loaded, and then prompt information of the reagent loading failure can be displayed on the display interface of the human-computer interaction device 13.
Therefore, it can be understood that, after the key file is introduced to the in-vitro diagnostic apparatus from the sale direction of the in-vitro diagnostic apparatus, the in-vitro diagnostic apparatus loads the reagent according to the reagent loading flow shown in fig. 7; and when the third password is input into the in-vitro diagnostic apparatus by the seller, the in-vitro diagnostic apparatus loads the reagent according to the original reagent loading process.
