For example, the full autosampler blood cell analysis measuring device may be based on a physical device as shown in fig. 2.
The embodiment of the invention also provides a full-automatic sampling blood cell analysis and measurement method, as shown in fig. 3, the method comprises the following steps:
step S1: and determining the loading condition of the test tube on the test tube rack in the process of transversely feeding the sample loading platform to the test tube rack.
Whether the test tube rack is loaded with test tubes or not is detected by the test tube detecting unit, and this step is performed with the specimen sample loading platform feeding the test tube rack laterally. That is, the subsequent steps are performed only in the case where the test tubes are loaded on the test tube rack, so as to avoid unnecessary procedure waste.
In a specific embodiment, the test tube detecting unit is a pair of light coupling, and under the condition that the test tube rack transversely feeds through the test tube and detects the correlation opto-coupler, if the test tube has or not detects the correlation opto-coupler and produces the signal of sheltering from, judge that there is the test tube to exist in the test tube rack, otherwise, confirm not having the loading in the test tube rack to have the test tube.
Step S2: in the case where it is determined that the test tube is loaded on the test tube rack, determining a test tube type of the test tube loaded in the test tube rack, wherein the test tube type includes a venous blood test tube and a peripheral blood test tube.
When a test tube is loaded on a test tube rack, a blood sample in the loaded test tube needs to be analyzed. In this embodiment, there may be two types of test tubes in the test tube rack, one is a normal venous blood test tube and one is a special peripheral blood test tube, and different test tubes correspond to different subsequent operation steps. Therefore, the tube type needs to be distinguished. Specifically, the test tube type of the test tube loaded in the test tube rack is detected by the test tube detecting unit, wherein the test tube type includes a venous blood test tube and a peripheral blood test tube.
In an alternative embodiment, the peripheral blood tube has a bottom thickness greater than the bottom thickness of the venous blood tube, wherein the bottom thickness of the tube is the distance between the bottom of the exterior of the tube and the bottom of the tube lumen (the bottom of the tube lumen that can contain the blood sample). For example, the bottom of the test tube lumen of the peripheral blood test tube is located in the middle of the test tube, and the thickness of the tube bottom is half of the overall height of the test tube, while the thickness of the tube bottom of the venous blood test tube is the general thickness of the test tube wall, and is negligible compared with the overall height of the test tube. Generally, the test tube is made of glass or PP, that is, the portion corresponding to the thickness of the tube bottom is light permeable, and is light permeable no matter whether a blood sample is filled in the inner cavity of the test tube.
In the case of containing a blood sample, the lower region of the tube corresponding to the bottom thickness of the peripheral blood tube is light-permeable, and in the case of containing a blood sample, the lower region of the tube is not light-permeable because the bottom thickness of the venous blood tube is small and the light-permeable region of the bottom is negligible.
In another alternative embodiment, as shown in fig. 4, the peripheral blood test tube comprises an outer tube and an inner tube, wherein the bottom of the inner tube is located in the middle region of the outer tube, and the lower region of the outer tube is light permeable.
As shown in fig. 4, the peripheral blood test tube includes a tube body 11 and a tube cap 12; the whole or the middle part of the tube cap 12 is made of rubber so that a sampling needle can penetrate through the tube cap; the tube body 11 comprises an inner tube body and an outer tube body, wherein the bottom of the inner tube body is provided with a tapered round bottom so as to facilitate the depth of the sampling needle immersed into the blood sample; the outer tube body is a skirt edge 111 formed by downwards extending a certain length of a straight edge above the taper of the bottom of the inner tube body along the height direction of the tube body, so that the tip blood collecting tube can be placed in the test tube rack to adapt to clamping and placing of the test tube clamping jaws without changing the test tube rack; the skirt 111 is in a transparent or semitransparent state near the bottom area, and does not shield the detection light of the vacuum blood collection tube. Specifically, as shown in fig. 5 and 6, fig. 5 and 6 show a case where a venous blood test tube and a peripheral blood test tube are loaded on a test tube rack, wherein, as shown in fig. 5, a blood sample in the venous blood test tube is assigned to a reference number 011, a blood sample in the peripheral blood test tube is assigned to a reference number 021, and as shown in fig. 6, a venous blood test tube is assigned to a reference number 010, and a peripheral blood test tube is assigned to a reference number 020 are loaded on the test tube rack 5.
In another alternative embodiment, the cuvette detecting unit is a photoelectric sensor, which may be a correlation optical coupler, for example, and determines the detection of the bottom or lower area of the cuvette by the correlation optical coupler, and determines the type of the cuvette according to the photoelectric information received by the correlation optical coupler. In this embodiment, the test tube detecting unit for determining the test tube type may be disposed at any working position on the sample loading platform before the blending position, that is, the test tube type is detected before the blending operation.
Optionally, test tube detecting element chooses for use the correlation opto-coupler, as shown in fig. 7, wherein, whether the first test tube detecting element who loads the test tube on the test-tube rack is correlation opto-coupler 8, set up in on the venous blood test tube mixing mechanism, the second test tube detecting element who detects the test tube type is correlation opto-coupler 10, set up in on the tip blood test tube mixing mechanism.
That is, when the test tube rack transversely feeds to a preset working position, if the test tube detection correlation optical coupler is not shielded, the test tube detection unit judges that the test tube is a micro peripheral blood test tube; if the test tube detects that the correlation opto-coupler is sheltered from, judge as the venous blood test tube. Specifically, the method of the embodiment of the invention realizes the detection of two test tube types, namely a venous blood test tube and a peripheral blood test tube, by newly adding a high-low level of a correlation optical coupler arranged in a blood sample area at the bottom of the test tube and judging whether the test tube is in a test tube state or not; the peripheral blood test tube is in a transparent or semitransparent state corresponding to the tube body area of the newly added correlation optical coupler.
Step S3: and determining a corresponding mixing mode according to the test tube type, and mixing the blood in the test tube by adopting the determined mixing mode.
In this embodiment, the venous blood test tube and the peripheral blood test tube correspond to different blending modes, and the amount and the position of the blood sample are different, so that it is necessary to determine the blending mode corresponding to the test tube type to perform blending operation on the blood in the test tube, so as to improve the effective rate and the accuracy of subsequent sample suction and analysis and measurement.
Specifically, in the case where the test tube type is a venous blood test tube, a normal mixing operation corresponding to the venous blood test tube is adopted to perform the mixing operation. For example, the test tube gripper 9 picks up the test tube from the tube rack and moves it above the rack, and the mixing of the blood sample is performed by reversing the direction of the test tube.
When the test tube type is a peripheral blood test tube, it is necessary to perform a kneading operation using a kneading operation corresponding to the peripheral blood type. Specifically, a peripheral blood tube mixing mechanism is used for mixing the blood sample in the test tube. Tip blood test tube mixing mechanism is inside to be provided with and to link up test tube storehouse, test tube support, brushless motor, eccentric block, at the in-process that carries out the mixing operation, and control will the test tube is placed in the test tube storehouse that link up of tip blood test tube mixing mechanism, makes the bottom of test tube and the test tube support butt of tip blood test tube mixing device to make the effect of the mixing operation in later stage best. The bottom of test tube with under the condition of tip blood test tube mixing mechanism's test tube support butt, the brushless motor of tip blood test tube mixing device drives the eccentric block and rotates, and then drives the test tube support of test tube institute butt produces vibrations, causes to link up tip blood test tube rotation swing and vibrations in the test tube storehouse to realize the mixing of the interior blood sample of test tube.
In another alternative embodiment, in order to save space of the device, the mixing mechanisms for mixing the venous blood test tube and the peripheral blood can be provided as the same mechanism, for example, both the peripheral blood test tube mixing mechanisms. Specifically, in this embodiment, when the test tube type is a venous blood test tube, a rotation speed parameter corresponding to the venous blood test tube is determined, and the brushless motor of the peripheral blood test tube blending mechanism performs blending operation on a blood sample in the test tube by using the determined rotation speed parameter. That is, different blending parameters (for example, the rotation speed parameter of the brushless motor) corresponding to the peripheral blood test tube and the venous blood test tube are adopted for different test tube types to perform blending operation.
As shown in fig. 8, a venous blood tube mixing mechanism is shown at 200, a peripheral blood tube mixing mechanism is shown at 300, and a sample sucking and sampling needle mechanism including a sampling needle 7 is shown at 400.
Step S4: and when the test tube rack is fed to the sample sucking position, determining the descending height according to the determined test tube type, and executing the descending action corresponding to the determined descending height by the sampling needle and sucking the sample.
As mentioned above, the height of the blood sample in different types of test tubes varies due to the different types of test tubes (bottom height) and the different amount of blood in the test tubes, which results in different heights for the sampling needle to take samples, and if the same height is used, the sample may be taken or not enough in some cases. Therefore, in the embodiment, in the case that the test tube rack is fed to the sample sucking position, it is necessary to determine the corresponding position of the sampling needle in the process of sucking the sample, i.e. the corresponding descending height, according to the type of the test tube, then control the sampling needle to perform the descending action corresponding to the determined descending height, and then perform the operation of sucking the sample, so as to improve the success rate of sucking the sample and improve the effectiveness of subsequent sample analysis.
Step S5: and analyzing and measuring the absorbed sample, after the analysis and measurement are completed, feeding the test tube rack to an unloading position, unloading and withdrawing to an unloading platform, and outputting an analysis and measurement result of the absorbed sample.
In the step, the sample analysis mechanism carries out analysis measurement on the sample sucked by the sampling needle, and outputs a corresponding analysis measurement result for use after the analysis measurement is finished; and, after the analysis and measurement is completed, the test tube on the test tube rack no longer needs to be operated, in which case the test tube on the test tube rack needs to be unloaded, that is, the test tube rack is controlled to be fed to the unloading position to be withdrawn to the unloading platform to complete the process of automatic sample feeding and analysis and measurement.
In the embodiment of the invention, specifically, after the test tube state and type are identified, for example, when a peripheral blood test tube is identified, the test tube clamping jaw on the venous blood test tube mixing mechanism is horizontally fed to a proper position from the ready position to clamp the peripheral blood test tube; then move upward along the test tube axial direction to a proper height, ensure to lift the test tube and draw off from the test tube rack and the space between the lifted test tube bottom and the test tube rack top surface allows the horizontal feeding insertion of the peripheral blood test tube mixing mechanism. That is to say, be provided with the test tube claw on the venous blood test tube mixing mechanism, the test tube claw is used for the test tube on the centre gripping test-tube rack in order to remove the test tube. In the embodiment of the invention, after the test tube state and type are identified, for example, when a peripheral blood test tube is identified, the test tube clamping jaw 9 on the venous blood test tube mixing mechanism firstly carries out horizontal feeding to a proper position in the test tube direction from the ready position, and clamps the peripheral blood test tube; then moves upward along the axial direction of the test tube to a proper height, ensures that the lifted test tube is drawn away from the test tube rack 5 and is lifted to the space between the bottoms of the test tubes and the top surface of the test tube rack 5 to allow the horizontal feeding insertion of the peripheral blood test tube mixing mechanism.
Specifically, the specific procedure of the above-described mixing operation of the peripheral blood test tube includes steps S31 to S33 shown in fig. 9, and before the steps of the corresponding mixing operation are described, the peripheral blood test tube mixing mechanism for performing the mixing operation is first described in detail:
as shown in fig. 10, the peripheral blood test tube mixing mechanism 300: comprises a feeding mechanism, a third horizontal bracket 21, a second horizontal bracket 19, a brushless motor 24 and an eccentric block 26; a test tube bin 22 is arranged on the third horizontal bracket 19, and a test tube holder with an inwards concave curved surface is arranged on the second horizontal bracket; the test tube holder 23 is used for supporting a peripheral blood collection tube, and the test tube bin 22 is used for limiting a test tube on the test tube holder 23; the brushless motor 24 of the peripheral blood test tube mixing mechanism drives the eccentric block 26 to rotate around the motor shaft of the brushless motor 24, and further drives the second horizontal support and the test tube holder to swing in a rotary mode.
