[0019] First embodiment:

[0020] See also Figures 1 to 3 ,in Figure 1 This is the overall structural diagram of the fully automatic quality control system of the blood analyzer. Figure 2 yes Figure 1 A magnified image of Figure 3 It is a schematic diagram of the installation structure of the first lever.

[0021] The utility model provides a fully automatic quality control system for a blood analyzer, including an ST module 101, wherein the ST module 101 includes a housing 102, a first lever 103, a second lever 104, a lateral lever 105, a beam coupler 106, a first rotating wheel 111, a test tube rack label reader 107, a conveyor belt 108, a scanning component 109 and a sampling component 110, wherein the scanning component 109 includes a photoelectric switch 112 and a first barcode reader 113, and the speed of quality control material testing is greatly improved by changing a single sampling into a multi-sampling automatic test, and at the same time, the quality control material information is changed from the previous manual input to automatically pulling from a cloud server, so as to avoid manual input errors. It can be understood that the aforementioned scheme can be used in the quality control system, and can also be used for scanning the barcode on the test tube.

The movement of the first lever 103, the second lever 104 and the horizontal lever 105 is mainly realized by a stepping motor, a linear guide rail plus a synchronous belt and a conveyor belt. The driving structure is a prior art and will not be described in detail here. The right side of the housing 102 is a test tube rack placement area, the left side is a test tube rack waiting and scheduling area, and the rear side is a scanning track. When in use, the test tube rack is placed on the housing 102 and the test tube rack is located at the test tube rack placement area. The first lever 103 pushes the test tube rack from the test tube rack placement area backwards into the scanning track, and in the scanning track, the horizontal lever 105 pushes the test tube rack to move horizontally to the scanning component 109, and the scanning component 109 scans the barcode on the test tube in the test tube rack. When the barcode reading is completed, the test tube rack is pushed to the leftmost end and then pushed forward into the test tube rack waiting scheduling area by the second lever 104. The test tube rack passes through the test tube rack label reader 107, and the test tube rack number is read by the test tube rack label reader 107 and sent to I The PU uploads the test tube rack number and the test tube barcode information, and the test tube rack continues to be pushed forward to the test tube rack waiting scheduling area, and waits here for scheduling to push the sample injection component 110. If scheduling allows the test tube rack to perform subsequent automatic quality control processes, the test tube rack is moved from the exit of the waiting scheduling area to the left into the sample injection component 110 through the rotation of the conveyor belt 108 to collect quality control samples, thereby achieving the purpose of no longer needing to frequently input information or frequently switching modes; this invention makes the fully automatic blood analysis system more in line with the needs of actual users, reduces the complexity of user use, helps doctors adapt to the equipment more easily, and reduces learning costs, thereby improving user satisfaction.

[0023] Secondly, the first rotating wheel 111 is rotatably connected to the housing 102 and is arranged on the housing 102; the photoelectric switch 112 is fixedly connected to the housing 102 and is arranged on the housing 102; the first barcode reader 113 is fixedly connected to the housing 102 and is arranged on the housing 102, the first rotating wheel 111 is driven to rotate by a stepping motor, and a tension spring is also installed on the housing 102, which can pull the first rotating wheel 111 to abut against the test tube; when the test tube rack moves to the left on the scanning track, it first passes through the photoelectric switch 112, and the photoelectric switch 112 is used to determine whether there is a test tube on the test tube position in the test tube rack. If there is a test tube, when the test tube rack passes the first barcode reader 113 to the left again, the barcode on the test tube is scanned by the first barcode reader 113, and at the same time, the first rotating wheel 111 is rotated and the test tube is driven to rotate, ensuring that the barcode on the test tube can be successfully read by the first barcode reader 113.

[0024] Second embodiment:

[0025] Based on the first embodiment, please refer to Figure 4 and Figure 5 , Figure 4 is a schematic structural diagram of the sample introduction component of the second embodiment, Figure 5 The second embodiment of the Figure 4 As shown in the enlarged view of point B, the sample introduction component 110 of this embodiment includes a chassis 201, a tray 202, a right sample introduction hook 203, a lateral sample introduction hook 205, an exit hook 206, a test tube rack presence detection optical coupler 207, a test tube presence detection optical coupler 208, a test tube rack number reader 209, a second barcode reader 210 and a second rotating wheel 211.

[0026] According to this specific embodiment, the chassis 201 is fixedly connected to the shell 102 and is located on one side of the shell 102; the tray 202 is fixedly connected to the chassis 201 and is located on one side of the chassis 201; the right-side injection hook 203 is slidably connected to the tray 202 and is arranged on the tray 202; the horizontal injection hook 205 is slidably connected to the tray 202 and is arranged on the tray 202; the exit hook 206 is slidably connected to the tray 202 and is arranged on the tray 202.

[0027] Among them, the test tube rack presence detection optical coupler 207 is fixedly connected to the tray 202 and is located on one side of the tray 202; the test tube presence detection optical coupler 208 is fixedly connected to the tray 202 and is located on one side of the tray 202; the test tube rack number reader 209 is fixedly connected to the tray 202 and is arranged on the tray 202.

[0028] Secondly, the second barcode reader 210 is fixedly connected to the chassis 201 and is located at one side of the chassis 201 ; the second rotating wheel 211 is rotatably connected to the chassis 201 and is disposed on the chassis 201 .

[0029] The movement of the right side sample injection hook 203, the horizontal sample injection hook 205 and the exit hook 206 is mainly realized by a stepper motor, a linear guide rail plus a synchronous belt and a conveyor belt. The driving structure is a prior art and will not be described in detail here. The test tube rack transported by the conveyor belt 108 moves to the tray 202. When the test tube rack detection optical coupler 207 detects the test tube rack, the right side sample injection hook 203 pushes the test tube rack backward so that the test tube rack can reach the rearmost area of ​​the tray 202. Then, when the test tube rack number information on the test tube rack is read by the test tube rack number reader 209 and it is the correct quality control test tube rack, the injection component 110 is allowed to start a series of subsequent actions such as pushing the test tube rack to the left for injection, otherwise a test tube rack type error will be reported. The horizontal sample injection hook 205 is used to push the test tube rack to the left so that the test tube rack can be pushed to the left. The rack can reach specific positions such as the test tube presence identification position, the test tube barcode reading position, the puncture sampling position, etc.; when the test tube rack presence detection optical coupler 207 detects that a test tube has passed, the test tube at this position will move to the left and reach the test tube barcode reading position to start the action of rotating the test tube and reading the test tube barcode, otherwise the test tube barcode reading action will not be started; the second barcode reader 210 is used to read the barcode information of the test tube at the test tube barcode reading position; the second rotating wheel 211 is used to rotate the test tube at the test tube barcode reading position so that the barcode on the test tube can be identified; the working principle of the second rotating wheel 211 is the same as that of the first rotating wheel 111, and no further details will be given here; when the test tube rack is pushed to the leftmost area of ​​the tray 202 by the horizontal sampling hook 205, the exit hook 206 will push the test tube rack forward out of the station.

[0030] This patented structure uses the test tube rack presence detection optical coupler 207 to identify whether a test tube rack has entered the tray 202 area from the housing 102. If yes, the automatic quality control process is started. The function of pushing the test tube rack backward to identify the type of the test tube rack is realized by the right side sample hook 203. The power and transmission mechanism of the right side sample hook 203 are mainly realized in the form of a stepper motor, a linear guide rail and a synchronous belt; the test tube rack number information on the running test tube rack is read by the test tube rack number reader 209. Only when the test tube rack number information is correct, the subsequent automatic quality control process action is allowed, otherwise the test tube rack type error information is reported. The function of pushing the test tube rack to the left is realized by the lateral sample feeding hook 205, and the power and transmission mechanism of the lateral sample feeding hook 205 are mainly realized in the form of a stepping motor, a linear guide rail and a synchronous belt; the test tube rack presence detection optical coupler 207 is used to identify whether a test tube is placed at this position of the test tube rack passing to the left. Only when a test tube is recognized at this position, the subsequent functions of rotating the test tube and reading the test tube barcode information are started; the test tube rotation function is realized by the second rotating wheel 211, so that the test tube at the test tube barcode reading position can be rotated for several circles, so that the barcode on the test tube can be read. The rack faces the second barcode reader 210 and is identified; when the test tube barcode information on the test tube barcode reading position is correct and it is a quality control test tube, the needle puncture and collection of quality control samples will be performed at the subsequent puncture sampling position; otherwise, when the test tube passes through the puncture sampling position, the puncture sampling action will not be started; the function of pushing the test tube rack forward out of the station is realized by the exit hook 206. When the test tube rack runs to the leftmost area of ​​the tray 202, the exit hook 206 will push the test tube rack forward out of the station, which also means that the automatic quality control process of the current quality control test tube rack is ended.

[0031] The actual use of automatic quality control is used to illustrate:

[0032] Step 1:

[0033] The IPU software pulls the quality control list from the cloud server. When each set of quality control materials is produced, a dedicated person will upload the quality control material information to the cloud server. After the IPU software is started, it will periodically obtain the latest quality control material target value table from the server. After the pull is successful, the specific quality control material list and its detailed information can be viewed in the IPU quality control plan interface.

[0034] Step 2:

[0035] Automatic testing of quality control materials.

[0036] 1. The user needs to place the quality control material in the test tube rack.

[0037] 2. IPU starts multi-injection test.

[0038] 3. Place the test tube rack with the quality control object in the rack entry area of ​​the ST module 101. The level of the optical coupler 106 for detecting the presence of the test tube rack in the test tube rack entry area changes, so that it is determined that a test tube rack has been put in. The ST module 101 drives the longitudinal motor in the rack entry area, thereby driving the first lever 103 forward. When the first lever 103 moves forward all the time until the first test tube rack on the motion path is pushed into the code scanning waiting area, after the code scanning waiting area detects the test tube rack, the ST module 101 stops driving the longitudinal motor and drives the transverse motor in the code scanning area to move, driving all The horizontal lever 105 pushes the test tube rack to the barcode scanning area, and only moves forward one tube position each time. The photoelectric switch 112 at the fixed detection position detects that there is a test tube in the tube position before driving the first rotating wheel 111 to rotate, thereby driving the test tube to rotate. The first barcode reader 113 keeps scanning the rotating test tube until the barcode is scanned or the scanning timeout occurs, and then stops the barcode scanning. After all the test tubes are scanned, the horizontal lever 105 pushes the test tube rack horizontally to the leftmost side of the code scanning area, and the horizontal lever 105 returns to the starting position to the right, and registers the test tube rack and all test tubes to the IPU software at the same time. After registration is completed, the second lever 104 on the left side of the code scanning area pushes the test tube rack into the out-of-rack area, and the longitudinal motor of the ST module 101 driving the left out-of-rack area drives the second lever 104 to move and push the test tube rack to the application scheduling position. The ST module 101 reads the test tube rack number through the test tube rack label reader 107 at the application scheduling position, thereby sending a scheduling request to the IPU software. After the IPU software allows scheduling, it will command the receiving device to extend the hook in advance to intercept the test tube rack. After the hook is extended, it will command the ST module 101 to push the test tube rack to the test track. The conveyor belt 108 of the test track rotates to transport the test tube to the receiving device. After the receiving device detects that the intercepted test tube rack is fully in place, it pushes the test tube rack from the test track into the rack entry area of ​​the sample introduction component 110 of the device, thereby completing the scheduling of the test tube rack.

[0039] 4. The ST module 101 transports the test tube rack with the quality control object to the INC control instrument; after the sample injection component 110 on the INC control instrument determines that a test tube rack has entered, it will automatically run and push the test tube rack backward to the rearmost area of ​​the tray 202; when the test tube rack number reader 209 recognizes that the information on the test tube rack is the correct quality control test tube rack, the horizontal injection hook 205 will automatically push the test tube rack to the left; when the test tube rack moves to the test tube presence identification position, the test tube rack presence detection optical coupler 207 will start the detection, and this position detects whether there is a test tube passing through and determines whether to start the second barcode reader 210 for barcode scanning later; when the test tube presence identification position detects that the existing test tube runs to the left to the test tube barcode reading position, the sample injection component 110 on the INC control instrument will turn on the second rotating wheel 211 and the second barcode reader 210 to automatically scan the barcode information on the test tube. After the scanning, the second barcode reader 210 will send the barcode number to the INC control software. Whether the test tube barcode information is the correct quality control test tube barcode determines whether the subsequent sampling needle puncture and quality control sample collection actions are performed.

[0040] 5. Based on the scanned barcode number, the INC control software actively asks the IPU software whether the test tube with the barcode on the test tube rack is to be tested for samples. After receiving the inquiry, the IPU software determines whether the test tube rack is a quality control test tube rack. If it is a quality control test tube rack, the IPU software determines whether the barcode is a target value table barcode based on the quality control plan enabled by the equipment. If so, the target value table is found based on the barcode, and the monitoring items enabled by the target value table are used to determine the test mode of the quality control object, thereby replying whether to perform the test and the specific test mode. After the INC control software receives the reply from the IPU software, if testing is required, the test mode of the test tube is recorded. When the test tube is pushed to the puncture sampling position, the INC control software starts the quality control object test according to the acquired test mode.

[0041] Step 3:

[0042] After INC completes the test of the quality control object, the test results are uploaded to the IPU software. After the IPU receives the data and recognizes it as the quality control result, it saves the quality control result according to the target value table corresponding to the barcode. Users can view the quality control results and quality control trend charts of the corresponding equipment through the quality control function of the IPU software.

[0043] Step 4:

[0044] After all the test tubes on the quality control test tube rack with the quality control materials completed the test process, the sample introduction component 110 pushes the test tube rack to the unloading area. The sample introduction unloading area will push the test tube rack to the designated position for applying to unload the test tube rack. Once the RFID at the position detects the test tube rack, the INC control software will send a request to the IPU software to schedule the test tube rack. After receiving the scheduling request, the IPU software will issue a corresponding scheduling reply to the INC control software. The INC control software determines whether to allow the test tube rack to be pushed to the return track based on the received scheduling reply. If allowed, the INC control software controls the sample introduction component 110 to push the test tube rack to the return track, and drives the return track to send the test tube rack back to the test tube rack storage device.
