Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention:
the present application will be described in further detail below with reference to specific embodiments and drawings.
In the embodiment, the blood analyzer only comprises one sampling needle, and before blood analysis, the blood sample is quantified and the quantified blood sample and reagent are discharged through only one sampling needle, namely, the internal quantification is carried out; and simultaneously, the sample liquid which is quantified and uniformly mixed is sucked by the sampling needle for subsequent detection. Specifically, as shown in fig. 1, the blood analysis method of the present embodiment includes the following steps:
step S101, a sampling needle sucks in a quantitative blood sample.
In this step, the test tube containing the blood sample is sent under a sampling needle, which aspirates a predetermined amount of blood sample, for example, 20 μ L, according to a predetermined amount.
Step S102, a quantitative reagent and a blood sample are discharged through a sampling needle.
After the sampling needle sucks a certain amount of blood sample, the control device controls the sampling needle to be communicated with the reagent storage device, and a certain amount of reagent, such as diluent, is discharged together with the blood sample through the sampling needle under the action of the power source. The specific amount of the discharged reagent is set according to the dilution ratio, and for example, a sample solution having a dilution ratio of 1:300 is required, and a dilution solution of 6mL is required for 20. mu.L of the blood sample. Compared with the existing semi-automatic blood analyzer and full-automatic blood analyzer, the quantitative blood sample is firstly sucked by the sampling needle, and then the quantitative reagent and the blood sample are discharged into an empty test tube together, so that the quantitative sample and the reagent outside the machine of an operator are not needed, and the manual operation is reduced. In addition, compared with the existing semi-automatic blood analyzer, the blood analysis method provided by the embodiment only uses one sampling needle to suck a fixed amount of blood samples and discharge, and has a simple structure.
Preferably, in this embodiment, the sucked blood sample is discharged first and then a certain amount of reagent is discharged immediately, so that the reagent simultaneously cleans the inner wall of the sampling needle when being discharged, and the reagent can directly clean the blood sample remaining on the inner wall of the sampling needle without opening the cleaning system to clean the blood sample remaining on the inner wall of the sampling needle. The metered amount of reagent and blood sample expelled through the sampling needle is received through a test tube or other container.
Step S103, mixing the discharged reagent and the blood sample to form a sample solution.
In this step, the discharged reagent and blood sample are mixed uniformly in a test tube or other container to form a sample solution with a preset ratio. It can be understood that, in this step, the mixed solution of the blood sample of the kit can be mixed uniformly by a special mixing device, or can be mixed uniformly by shaking the test tube.
And step S104, sucking part of sample liquid through the sampling needle.
In the step, after the reagent and the blood sample are uniformly mixed to form the sample liquid, the blood sample is diluted, and the subsequent blood analysis and detection can be completed through the sample liquid sucked by the sampling needle. After the sampling needle sucks part of the sample liquid, the rest sample liquid is reserved; when the retest is required, at least a part of the remaining sample liquid is sucked in through the sampling needle to perform the detection. Compared with a whole blood mode analysis method of a full-automatic blood analyzer, the blood analysis method provided by the embodiment can retain the residual sample liquid, so that re-sampling is not needed when the time of re-examination is needed, and troubles of medical staff and patients are reduced.
And S105, conveying part of the sample liquid sucked by the sampling needle to a detection device for detection.
In this step, after the sampling needle inhales a part of sample liquid, directly transport the part of sample liquid inhaled by the sampling needle to the detection device for detection through the transport pipeline communicated with the sampling needle. For full-automatic blood analyzer, the blood analysis method that this embodiment provided, the sampling needle need not carry out level and vertical motion and send the sample to detection device (for example counting cell) top, adds detection device with sample liquid again and detects, and this embodiment blood sample is direct to be transported to detection device through the transport pipeline with sampling needle intercommunication and is detected, has simplified operation flow and greatly reduced blood analyzer structure complexity.
Compared with the existing semi-automatic and full-automatic blood analyzers, the blood analysis method provided by the embodiment firstly sucks a quantitative blood sample through the sampling needle and then discharges the quantitative reagent and the blood sample together, an operator does not need to quantify the sample and the reagent outside the machine, and manual operation is reduced; through discharging the reagent behind the blood sample earlier, can also wash the sampling needle inner wall when discharging the reagent. In addition, compared with the existing semi-automatic blood analyzer, the sample is quantitatively sucked and discharged only through one sampling needle, and the structure is simple; for current full-automatic blood analyzer, owing to dilute, inhale the sample liquid of part mixing through this sampling needle, remaining sample liquid can be stayed the reinspection, reduce medical personnel and patient's puzzlement, sampling needle inhales partial sample liquid back simultaneously, directly transports detection device through the transportation pipeline with the sampling needle intercommunication and detects, sampling needle does not need level and vertical motion like this, the flow has been simplified and greatly reduced blood analyzer's structure complexity. In addition, the blood analysis method provided by the embodiment adopts a unified flow for all blood analysis, and adopts the unified step method regardless of the whole blood mode or the pre-dilution mode, so that the detection results are close, the same calibration coefficient can be adopted for calibration, and the use by an operator is facilitated.
In another embodiment, a cleaning step is added to the steps of the previous embodiment. After the sampling needle sucks a blood sample or/and a sample liquid, the outer wall of the sampling needle is automatically cleaned through a cleaning system, and pollution is prevented. In particular, the outer wall of the sampling needle may be cleaned by axial movement of a swab of the cleaning system relative to the sampling needle. Compared with the existing semi-automatic blood analyzer, in the embodiment, the outer wall of the sampling needle is automatically cleaned by the swab without being wiped by a paper towel, so that the biological risk and the hole plugging probability are reduced.
This washing step may be performed after the step S101 of the previous embodiment is performed, that is, after the sampling needle sucks a certain amount of blood sample, the swab may perform a first washing on the outer wall of the sampling needle to wash the blood sample remaining on the outer wall of the sampling needle, and the first washing may be performed in parallel with the step S102 or step S103 of the previous embodiment and may be performed before the step S104 is performed. After the step S104 of the foregoing embodiment is performed, that is, after the sampling needle sucks a part of the sample liquid, the swab performs a second cleaning on the outer wall of the sampling needle to clean the sample liquid remaining on the outer wall of the sampling needle, and the second cleaning may be performed in parallel with the step S105 of the foregoing embodiment, so that the time of the whole process may be reduced. Of course, since the blood sample remaining on the outer wall of the sampling needle after the sampling needle sucks a certain amount of blood sample has little influence on the contamination of the sample solution sucked into the subsequent sampling needle, since the blood samples are the same, the cleaning step may be performed after step S104 of the foregoing embodiment is performed, that is, after the sampling needle sucks a part of the sample solution, and the cleaning step is performed in parallel with step S105 of the foregoing embodiment, so that the time of the whole process may be reduced.
In another embodiment, in order to control the flow of steps in the foregoing embodiments, the whole flow may be controlled and executed by an input device, such as a touch screen or a key. In this embodiment, the blood analysis method only interacts with the operator through one key, and the operator controls the whole blood analysis process through one key, specifically, as shown in fig. 2, the blood analysis method includes the following steps:
step S201, a state to be measured.
This step is the state to be detected.
Step S202, whether the key is pressed for the first time is detected, if the key is pressed for the first time, the step S203 is executed, and if not, the step S201 is returned to.
Step S203, the sampling needle sucks in a quantitative blood sample, and the outer wall of the sampling needle is cleaned after the quantitative blood sample is sucked.
In this embodiment, the step S101 of the previous embodiment is the same as the step S203 of the previous embodiment in which the sampling needle sucks a quantitative blood sample, and the description thereof is omitted. The outer wall of the sampling needle is cleaned after the intake of the metered blood sample, in particular by axially moving a swab of the cleaning system relative to the sampling needle.
And step S204, prompting to receive the blood sample and the reagent information, detecting whether the key is pressed for the second time, if so, executing step S205, otherwise, returning to step S201 after the cleaning is finished.
If the key is detected to be pressed for the second time within the first preset time, step S205 is executed. If the second pressing of the key is not detected within the first preset time, which indicates that the operation of the operator is wrong or the follow-up steps are not needed, the system enters a cleaning state, the cleaning system cleans the inner wall of the sampling needle and a transportation pipeline communicated with the sampling needle, and the system returns to the state to be detected of the step S201 after the cleaning is finished.
And S205, discharging the quantitative reagent and the blood sample through a sampling needle, and mixing uniformly to form a sample liquid after discharging.
Step S205 is the same as steps S102-S103, and is not repeated herein.
And step S206, prompting measurement information, detecting whether the key is pressed for the third time, if so, executing step S207, otherwise, returning to step S201.
If the third pressing of the key is detected within the second preset time, step S207 is executed. If the third pressing of the key is not detected within the second preset time, which indicates that the operation of the operator is wrong or the subsequent steps are not needed, the system enters a cleaning state, and since the blood sample is discharged first and then the reagent is discharged in step S205, and the residual blood sample on the inner wall of the sampling needle is cleaned while the reagent is discharged, the cleaning system does not need to be started for cleaning, and the system can directly return to the state to be detected in step S201.
Step S207, sucking part of the sample liquid through the sampling needle.
This step is the same as step S104 in the previous embodiment, and is not described herein again.
And step S208, cleaning the outer wall of the sampling needle.
In particular, the outer wall of the sampling needle may be cleaned by axial movement of the swab relative to the sampling needle.
And S209, conveying part of the sample liquid sucked by the sampling needle to a detection device for detection.
This step is the same as step S105 of the previous embodiment, and is not repeated here.
In this embodiment, step S208 and step S209 may be performed in parallel, so as to reduce the time of the whole process.
In the embodiment, besides the beneficial effects of the foregoing embodiment, one key is used for interacting with an operator, that is, the operator can control and realize that one key has multiple functions in the whole blood analysis process, including functions of sample suction, sample discharge, measurement and the like, the functions can be automatically switched, and the device key and the operator operation process are simplified; meanwhile, the function of the current key is informed through the display information prompt, so that the use of an operator is facilitated. In addition, in addition to controlling the operation flow through the input device, the whole blood analysis flow may also be completed through automatic sensing, including a cleaning step, for example, after sensing that there is a blood sample under the sampling needle, the rectification flow is started, and the aforementioned steps S101 to S105 and the cleaning step are completed according to a preset time, which is not limited herein.
