TECHNICAL FIELD

[0001] The present application relates to the technical field of biomedical equipment, and particularly provides a blood type detector. BACKGROUND

[0002] With the rapid development of social economy, people's cognition of their own blood type is becoming more and more clear. Blood type refers to the antigen type on the surface of blood components (including red blood cells, white blood cells and platelets). The commonly used blood type refers to the specific antigen type on the red blood cell membrane. In the human blood type system, the blood type systems currently found and recognized by the International Blood Transfusion Association mainly include ABO blood type system, Rh blood type system, MNS blood type system, P blood type system, etc. Among them, the ABO blood type system and the Rh blood type system are the most commonly used.

[0003] In some scenarios (such as blood donation room, emergency room, etc.), it is necessary to quickly obtain the blood type. In order to improve the blood type detection rate, the existing technology generally uses a blood type detector for detection. However, the existing blood type detector has a low automation level, which leads to poor user experience.

[0004] Therefore, there is a need in the art for a new technical solution to solve the above problems. SUMMARY

[0005] The present application aims to solve the above technical problems, i.e., to solve the problem of low automation degree of the existing blood type detector, which leads to poor user experience.

[0006] In a first aspect, the present application provides a blood type detector, comprising a housing, a feeding device and a sample filling device installed in the housing, the feeding device comprising a feeding mechanism and a fixing mechanism for carrying a blood collection tube, the feeding mechanism being capable of moving with the fixing mechanism and the blood collection tube fixed on the fixing mechanism to make the blood collection tube communicate with the sample filling device, the sample filling device being capable of filling the blood sample in the blood collection tube into a reaction cup, and the feeding mechanism being further capable of cooperating with the sample filling device to unload the blood collection tube on the fixing mechanism from the fixing mechanism. Through such a design, the detector of the present application can automatically complete the feeding and unloading of the blood collection tube, thereby improving the automation degree of the detector. In addition, the sample filling device can also play a role when unloading the blood collection tube on the basis of realizing the sample filling function, thereby realizing one thing with multiple functions and simplifying the structure.

[0007] In the preferred technical scheme of the blood type detector, the feeding mechanism comprises a horizontal feeding mechanism and a vertical feeding mechanism, the fixing mechanism is mounted on the vertical feeding mechanism, the horizontal feeding mechanism can drive the vertical feeding mechanism and the fixing mechanism to move in the horizontal direction, and the vertical feeding mechanism can drive the fixing mechanism to move in the vertical direction; the horizontal feeding mechanism can cooperate with the sample filling device to unload the blood collection tube on the fixing mechanism from the fixing mechanism.

[0008] In the preferred technical scheme of the blood type detector, the sample filling device is provided with a columnar structure extending in the horizontal direction, the fixing mechanism comprises horizontal fixing plates and a vertical fixing plate, the number of the horizontal fixing plates is two and they are spaced apart in the vertical direction, the top end and the bottom end of the vertical fixing plate are connected with corresponding horizontal fixing plates respectively, the horizontal fixing plates are provided with fixing through holes for fixing the blood collection tube, the horizontal fixing plates are provided with unloading openings in communication with the fixing through holes on the side away from the vertical fixing plate, the vertical fixing plate is provided with an unloading through hole allowing the columnar structure to pass through at the position corresponding to the columnar structure, and the unloading through hole is correspondingly arranged with the fixing through hole, so that the columnar structure passing through the unloading through hole can contact the blood collection tube in the fixing through hole, thereby pushing the blood collection tube out of the fixing through hole from the unloading opening in the process that the horizontal feeding mechanism continues to move with the blood collection tube towards the columnar structure. Through such an arrangement, it is convenient to install and unload the blood collection tube, and the working efficiency is improved.

[0009] In the preferred technical scheme of the blood type detector, the horizontal fixing plate comprises a plate-shaped body connected with the vertical fixing plate and an elastic clamping block mounted on the plate-shaped body, and the fixing through hole and the unloading opening are formed on the elastic clamping block, and the inner diameter of the fixing through hole is not greater than the outer diameter of the blood collection tube so as to clamp and fix the blood collection tube. Through such an arrangement, the stability of the blood collection tube can be improved, and the working efficiency is not affected by the damage of the blood collection tube.

[0010] In the preferred technical scheme of the blood type detector, the elastic clamping block is provided with a hollow structure near the fixing through hole, so that the opening size of the unloading opening is easier to increase when the blood collection tube is unloaded. Through such an arrangement, the unloading work of the blood collection tube can be more smoothly carried out.

[0011] In the preferred technical scheme of the blood type detector, the plate-shaped body is provided with a receiving slot, and the elastic clamping block is clamped in the receiving slot. Through such an arrangement, it is convenient to install and replace the elastic clamping block.

[0012] In the preferred embodiment of the blood typing instrument described above, the vertical dimension of the receiving slot is smaller than the thickness of the plate-shaped body. The plate-shaped body has a receiving hole corresponding to the fixing through hole, which communicates with the receiving slot and allows the blood collection tube to pass through. This design improves the stability of the elastic clamping block.

[0013] In the preferred embodiment of the blood typing instrument described above, the plate-shaped body is provided with an unloading groove at a position corresponding to the unloading port, which communicates with the receiving slot. The unloading groove is configured to allow the blood collection tube to pass through but not the elastic clamping block to pass through, preventing the elastic clamping block from dislodging from the receiving slot. This configuration improves the stability of the elastic clamping block.

[0014] In the preferred embodiment of the aforementioned blood typing instrument, the sample dispensing device includes a sample dispensing mechanism and a liquid level detection mechanism. The sample dispensing mechanism is connected to the blood collection tube and can dispense the blood sample from the blood collection tube into the reaction cup. The liquid level detection mechanism can detect the liquid level in the blood collection tube to ensure that the amount of blood sample dispensed into the reaction cup meets the testing requirements. The columnar structure is disposed on the liquid level detection mechanism. This configuration improves the accuracy of the test results.

[0015] In the preferred embodiment of the above-mentioned blood typing instrument, the sample dispensing mechanism includes a dispensing rubber stopper, an air tube, and a pressure pump. The dispensing rubber stopper has a channel, the top end of which is connected to the pressure pump through the air tube, and the bottom end of which is connected to the blood collection tube.

[0046] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that the embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application.

[0047] It should be noted that, in the description of the present application, the terms "left", "right", "up", "down", "top", "bottom", and the like indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings, which is only for the convenience of description, and does not indicate or imply that the device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application. In addition, the terms "first", "second", "third" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance.

[0048] In addition, it should also be noted that, in the description of the present application, unless otherwise explicitly specified and limited, the terms "providing", "connecting", "mounting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0049] Specifically, the present application provides a blood type detector, as shown in Figure 1 and Figure 2 The blood type detector of the present application comprises a shell 100 and a feeding device 20 and a sample filling device 30 installed in the shell 100.

[0050] The feeding device 20 can move with the blood collection tube to make the blood collection tube communicate with the sample filling device 30, and the sample filling device 30 can fill the blood sample in the blood collection tube into the reaction cup 80.

[0051] Specifically, after the staff collects the blood sample through the blood collection tube, the blood collection tube is placed on the feeding device 20, the feeding device 20 moves the blood collection tube from the placing position to the sample filling position, and the top end of the blood collection tube is communicated with the sample filling device 30, the sample filling device 30 applies pressure to the blood collection tube to make the blood sample in the blood collection tube fill into the reaction cup 80 located at the sample filling position.

[0052] Preferably, the blood collection tube of the present application is a siphon tube 10.

[0053] It should be noted that in actual applications, other types of blood collection tubes can also be used by those skilled in the art, such as conical blood collection tubes, etc., and the present application does not limit this. Of course, the present application preferably uses a siphon tube 10, which has a faster blood collection speed. The technical solutions of the present application will be introduced below with the siphon tube 10 as an example.

[0054] Preferably, as shown in Figure 1 and Figure 2 The blood type detector of the present application further comprises a reagent filling device 40 installed in the shell 100, which can fill the detection reagent into the reaction cup 80.

[0055] After the blood sample in the siphon tube 10 is filled into the reaction cup 80, the detection reagent is also filled into the reaction cup 80 (at the reagent filling position) by the reagent filling device 40. Through the reaction result of the detection reagent and the blood sample, the blood type of the blood sample can be determined.

[0056] It should be noted that in actual applications, the sample filling position and the reagent filling position can be arranged at the same position. In this case, after the blood sample in the siphon tube 10 is filled into the reaction cup 80, the reaction cup 80 does not need to be moved, and the detection reagent can be directly filled into the reaction cup 80 by the reagent filling device 40; or the sample filling position and the reagent filling position can also be arranged separately. In this case, after the blood sample in the siphon tube 10 is filled into the reaction cup 80, the reaction cup 80 needs to be moved from the sample filling position to the reagent filling position, and then the detection reagent is filled into the reaction cup 80 by the reagent filling device 40. This flexible adjustment and change deviating from the principles and scope of the present application should be limited within the protection scope of the present application.

[0057] Preferably, as shown in Figure 1 and Figure 2 The blood type detector of the present application further comprises a shaking and mixing device 60 installed in the shell 100, which can carry the reaction cup 80 and mix the blood sample and the detection reagent filled into the reaction cup 80.

[0058] After the blood sample and the detection reagent are filled into the reaction cup 80, the reaction cup 80 is shaken by the shaking and mixing device 60 to mix the blood sample and the detection reagent filled into the reaction cup 80, thereby improving the accuracy of the detection result.

[0059] Preferably, as shown in Figure 1 and Figure 2As shown in the drawings, the blood type detector of the present application further comprises an image recognition device 110 installed in the shell 100, the image recognition device 110 can collect the image of the blood sample mixed with the detection reagent in the reaction cup 80, so as to output the blood type according to the collected image.

[0060] By collecting the image through the image recognition device 110, and then analyzing and processing the collected image, the blood type is output, which can avoid the situation of manual misjudgment, and further improve the accuracy of the detection result.

[0061] It should be noted that in actual application, the image recognition device 110 can directly analyze and process the collected image and output the blood type, or the image recognition device 110 can also transmit the collected image to the control device of the blood type detector, and the control device analyzes and processes the collected image and outputs the blood type, etc. Such flexible adjustment and change and deviation from the principles and scope of the present application should be limited within the protection scope of the present application.

[0062] Exemplarily, the image recognition device 110 comprises a camera collection module and a data transceiver module, the camera collection module can collect the image, and the image information is sent to the control device of the blood type detector through the data transceiver module for analog-digital conversion, data analysis, and then the blood type is output.

[0063] It should be noted that in actual application, the blood type can be output in the form of voice broadcast, or the blood type can be displayed in the form of text on the display screen 101 of the blood type detector, etc. Such flexible adjustment and change and deviation from the principles and scope of the present application should be limited within the protection scope of the present application.

[0064] Preferably, as shown in the drawings, Figure 1 and Figure 2 The blood type detector of the present application further comprises a label storage member 120 installed on the shell 100, the number of the label storage member 120 is multiple, and different types of blood type labels are respectively stored in the label storage member 120.

[0065] By setting the label storage member 120 capable of storing the blood type label, when the blood type detector displays the detection result, the staff directly picks up the blood type label in the label storage member 120 corresponding to the detection result for labeling, which is very convenient, and the user's use experience is better.

[0066] It should be noted that in actual application, the specific number of the label storage member 120 can be flexibly set by those skilled in the art, for example, the number of the label storage member 120 can be set to two, three or four, etc.

[0067] Preferably, as shown in the drawings, Figure 1 andFigure 2 As shown, the number of the label storage members 120 of the present application is four, and the A-type label, the B-type label, the AB-type label and the O-type label are respectively stored.

[0068] Preferably, the blood type detection of the present application further comprises indicator lights (not shown in the figure) arranged on the front panel of the label storage member 120.

[0069] When the blood type detection instrument detects the blood type of the blood sample, the corresponding indicator light is lit, which can prevent the staff from taking the wrong blood type label, and further improves the user experience.

[0070] Preferably, as shown, Figure 1 The shell 100 is provided with a mounting port (not shown in the figure) at the position corresponding to the label storage member 120, and the label storage member 120 is inserted into the shell 100 from the mounting port.

[0071] Exemplarily, the number of the label storage members 120 is four, and four mounting ports are arranged on the front panel of the shell 100, and the four label storage members 120 are respectively inserted into the corresponding mounting ports.

[0072] Preferably, as shown, Figure 1 and Figure 2 The blood type detection instrument of the present application further comprises a consumable storage member 90 and a loading and unloading device 70 mounted in the shell 100.

[0073] Among them, the consumable storage member 90 can store a plurality of reaction cups 80, and the loading and unloading device 70 can load the reaction cup 80 located in the consumable storage member 90 to the oscillation and mixing device 60, and can unload the reaction cup 80 from the oscillation and mixing device 60 after the image recognition device 110 finishes collecting the image.

[0074] By setting the loading and unloading device 70, the loading and unloading of the reaction cup 80 can be automatically realized.

[0075] It should be noted that in actual application, those skilled in the art can also set the loading and unloading device 70 to only be able to load the reaction cup 80 located in the consumable storage member 90 to the oscillation and mixing device 60, or also can set the loading and unloading device 70 to only be able to unload the reaction cup 80 from the oscillation and mixing device 60 after the image recognition device 110 finishes collecting the image. Such flexible adjustment and change deviating from the principles and scope of the present application should be limited within the protection scope of the present application.

[0076] Of course, the application preferably sets the loading and unloading device 70 to be capable of loading the reaction cup 80 in the consumable storage member 90 onto the oscillation and mixing device 60 and unloading the reaction cup 80 from the oscillation and mixing device 60 after the image recognition device 110 finishes collecting the image.

[0077] Preferably, as shown in Figure 1 , Figure 2 and Figure 10 , the sample loading position and the reagent loading position of the blood type detector of the application are spaced apart along the X direction, the image recognition device 110 is located above the reagent loading position, and the image collection end thereof is arranged downward, and the blood type detector of the application further comprises a translation device 50 installed in the housing 100, which is capable of moving the oscillation and mixing device 60 between the sample loading position and the reagent loading position.

[0078] The application separately sets the sample loading position and the reagent loading position, as shown in Figure 2 , the translation device 50 moves the oscillation and mixing device 60 to the sample loading position, the loading and unloading device 70 pushes the reaction cup 80 in the consumable storage member 90 out and loads the reaction cup 80 onto the oscillation and mixing device 60, and the sample loading device 30 loads the blood sample in the pipette 10 into the reaction cup 80, as shown in Figure 10 , the translation device 50 moves the oscillation and mixing device 60 and the reaction cup 80 on the oscillation and mixing device 60 to the reagent loading position, the reagent loading device 40 loads the detection reagent into the reaction cup 80, the oscillation and mixing device 60 is started to mix the blood sample and the detection reagent loaded into the reaction cup 80, and the image recognition device 110 collects the image.

[0079] Preferably, as shown in Figure 2 to Figure 4 , the feeding device 20 of the application comprises a feeding mechanism and a fixing mechanism 230 for carrying the pipette 10.

[0080] The feeding mechanism is capable of moving the fixing mechanism 230 and the pipette 10 fixed on the fixing mechanism 230 to communicate the pipette 10 with the sample loading device 30, and the feeding mechanism is further capable of cooperating with the sample loading device 30 to unload the pipette 10 on the fixing mechanism 230 from the fixing mechanism 230.

[0081] Specifically, the staff places the siphon 10 on the fixing mechanism 230, the feeding mechanism moves the fixing mechanism 230 and the siphon 10 on the fixing mechanism 230 towards the sample adding device 30, and the siphon 10 is in communication with the sample adding device 30. After the sample adding device 30 adds the blood sample in the siphon 10 to the reaction cup 80, the feeding mechanism continues to move the siphon 10 towards the sample adding device 30, and cooperates with the sample adding device 30 to automatically unload the siphon 10 from the fixing mechanism 230, without the need for manual unloading of the siphon 10, and the user experience is better.

[0082] Preferably, as shown in Figure 2 and Figure 3 , the feeding mechanism of the present application comprises a horizontal feeding mechanism 210 and a vertical feeding mechanism 220, and the fixing mechanism 230 is installed on the vertical feeding mechanism 220.

[0083] The horizontal feeding mechanism 210 can drive the vertical feeding mechanism 220 and the fixing mechanism 230 to move in the horizontal direction, and the vertical feeding mechanism 220 can drive the fixing mechanism 230 to move in the vertical direction; the horizontal feeding mechanism 210 can also cooperate with the sample adding device 30 to unload the siphon 10 on the fixing mechanism 230 from the fixing mechanism 230.

[0084] Specifically, the staff places the siphon 10 on the fixing mechanism 230, the horizontal feeding mechanism 210 moves the vertical feeding mechanism 220, the fixing mechanism 230 and the siphon 10 towards the sample adding device 30, and after moving to the set position, the siphon 10 is aligned with the sample adding device 30, and the vertical feeding mechanism 220 moves the fixing mechanism 230 and the siphon 10 vertically upwards to make the top end of the siphon 10 in communication with the sample adding device 30.

[0085] After the sample adding device 30 adds the blood sample in the siphon 10 to the reaction cup 80, the horizontal feeding mechanism 210 moves the vertical feeding mechanism 220, the fixing mechanism 230 and the siphon 10 towards the sample adding device 30, and the sample adding device 30 abuts against the siphon 10 to unload the siphon 10 from the fixing mechanism 230. Of course, before moving the horizontal feeding mechanism 210 with the siphon 10 towards the sample adding device 30, the vertical fixing mechanism 230 can first move the fixing mechanism 230 and the siphon 10 downwards to separate the siphon 10 from the sample adding device 30.

[0086] Preferably, as shown in Figure 2 to Figure 8 , the sample adding device 30 is provided with a columnar structure 3211 extending in the horizontal direction, and the fixing mechanism 230 comprises a horizontal fixing plate 231 and a vertical fixing plate 232.

[0087] The number of horizontal fixing plates 231 is two and they are spaced apart in the vertical direction. The top end and the bottom end of the vertical fixing plate 232 are connected to the corresponding horizontal fixing plate 231. The horizontal fixing plate 231 is provided with a fixing hole 23121 for fixing the siphon 10. The horizontal fixing plate 231 is provided with an unloading port 23122 on the side away from the vertical fixing plate 232, which communicates with the fixing hole 23121. The vertical fixing plate 232 is provided with an unloading hole 2321 at the position corresponding to the columnar structure 3211, which allows the columnar structure 3211 to pass through. The unloading hole 2321 is correspondingly arranged with the fixing hole 23121, so that the columnar structure 3211 passing through the unloading hole 2321 can contact the siphon 10 located in the fixing hole 23121, thereby pushing the siphon 10 out of the fixing hole 23121 from the unloading port 23122 during the movement of the horizontal feeding mechanism 210 with the siphon 10 towards the columnar structure 3211.

[0088] Specifically, when the siphon 10 needs to be unloaded, the columnar structure 3211 on the sample filling device 30 passes through the unloading hole 2321 on the fixing mechanism 230. The front end of the columnar structure 3211 (the left end of the columnar structure 3211 as viewed from the top) abuts against the siphon 10. The horizontal feeding mechanism 210 continues to move with the siphon 10 towards the columnar structure 3211, so that the columnar structure 3211 pushes the siphon 10 out of the fixing hole 23121 from the unloading port 23122 on the fixing mechanism 230, completing the unloading of the siphon 10. After being extruded by the siphon 10, the unloading port 23122 has a larger opening size, so that the siphon 10 can be smoothly pushed out. Figure 8 The front end of the columnar structure 3211 (the left end of the columnar structure 3211 as viewed from the top) abuts against the siphon 10. The horizontal feeding mechanism 210 continues to move with the siphon 10 towards the columnar structure 3211, so that the columnar structure 3211 pushes the siphon 10 out of the fixing hole 23121 from the unloading port 23122 on the fixing mechanism 230, completing the unloading of the siphon 10. After being extruded by the siphon 10, the unloading port 23122 has a larger opening size, so that the siphon 10 can be smoothly pushed out.

[0089] Preferably, as shown in Figure 4 to Figure 7 The horizontal fixing plate 231 includes a plate-shaped body 2311 connected to the vertical fixing plate 232 and an elastic clamping block 2312 mounted on the plate-shaped body 2311. The fixing hole 23121 and the unloading port 23122 are both formed on the elastic clamping block 2312. The inner diameter of the fixing hole 23121 is not greater than the outer diameter of the siphon 10, so as to clamp and fix the siphon 10.

[0090] The elastic clamping block 2312 is made of elastic non-metallic material (such as rubber, etc.).

[0092] By setting the empty structure 23123, deformation is more likely to occur near the fixed hole 23121, so that a small force can be used to unload the siphon 10 from the fixed mechanism 230, preventing the siphon 10 from being damaged and unable to be smoothly unloaded.

[0112] It should be noted that in actual application, the vertical feeding mechanism 220 can also be set as a hydraulic cylinder driving mechanism, or the above-mentioned lead screw and sliding block can be replaced by a gear and a rack, etc. Such adjustment and change of the specific structure of the vertical feeding mechanism 220 does not deviate from the principles and scope of the present application, and should be limited within the protection scope of the present application. Of course, the present application preferably sets the vertical feeding mechanism 220 as the structure as introduced above, which is simple in structure and better in stability.

[0113] Preferably, as shown in Figure 2 、 Figure 3 and Figure 8 , the sample adding device 30 of the present application comprises a sample adding mechanism 31 and a liquid level detection mechanism 32.

[0114] The sample adding mechanism 31 can be in communication with the siphon tube 10 and can add the blood sample in the siphon tube 10 into the reaction cup 80, and the liquid level detection mechanism 32 can detect the liquid level in the siphon tube 10 so as to ensure that the amount of the blood sample added into the reaction cup 80 meets the detection requirement, and the columnar structure 3211 is arranged on the liquid level detection mechanism 32.

[0115] Specifically, before the sample adding mechanism 31 adds the blood sample in the siphon tube 10 into the reaction cup 80, the liquid level detection mechanism 32 first detects the blood sample in the siphon tube 10 to detect whether the amount of the blood sample in the siphon tube 10 is sufficient, and if the amount of the blood sample is sufficient, the sample adding mechanism 31 is caused to add the blood sample in the siphon tube 10 into the reaction cup 80.

[0116] The columnar structure 3211 is arranged on the liquid level detection mechanism 32, that is, the horizontal feeding mechanism 210 can cooperate with the liquid level detection mechanism 32 to unload the siphon tube 10 on the fixing mechanism 230 from the fixing mechanism 230.

[0117] It should be noted that in actual application, the columnar structure 3211 can also be arranged on the sample adding mechanism 31, that is, the horizontal feeding mechanism 210 can cooperate with the sample adding mechanism 31 to unload the siphon tube 10 on the fixing mechanism 230 from the fixing mechanism 230, which does not deviate from the principles and scope of the present application, and should be limited within the protection scope of the present application. Of course, the present application preferably arranges the columnar structure 3211 on the liquid level detection mechanism 32.

[0118] Preferably, as shown in Figure 2 、 Figure 3 and Figure 8 , the liquid level detection mechanism 32 comprises a detection bracket 321 and a liquid level detection sensor (not shown in the figure).

[0119] Among them, two columnar structures 3211 are set on the detection bracket 321 and are distributed at intervals along the vertical direction. Two unloading through holes 2321 are also provided on the vertical fixing plate 232 of the fixing mechanism 230. The two unloading through holes 2321 are respectively set to correspond to the two columnar structures 3211. There are also two liquid level detection sensors, which are respectively installed on the corresponding columnar structures 3211. The liquid level detection sensor located above (denoted as the first liquid level detection sensor) is used to detect the lowest effective liquid level in the siphon tube 10, and the liquid level detection sensor located below (denoted as the second liquid level detection sensor) is used to detect the highest allowable remaining liquid level in the siphon tube 10.

[0120] Specifically, before the sample filling mechanism 31 fills the blood sample in the siphon tube 10 into the reaction cup 80, the first liquid level detection sensor first detects the blood sample in the siphon tube 10 to check whether the blood sample in the siphon tube 10 is at or above the minimum effective liquid level. The minimum effective liquid level represents the lower limit of the total amount of blood sample in the siphon tube 10. If the blood sample is at or above the minimum effective liquid level, it means that the amount of blood sample is sufficient, and then the sample filling mechanism 31 fills the blood sample in the siphon tube 10 into the reaction cup 80.

[0121] During the blood sample filling process, the blood sample in the siphon tube 10 is detected by the second liquid level detection sensor to detect whether the blood sample in the siphon tube 10 has dropped to or below the maximum allowable remaining liquid level. The maximum allowable remaining liquid level represents the lower limit of the blood sample filling volume. If the blood sample drops to or below the maximum allowable remaining liquid level, it means that the amount of blood sample added to the reaction cup 80 is sufficient, and the sample filling mechanism 31 can stop filling. Of course, the sample filling mechanism 31 can also fill all the blood sample in the siphon tube 10 into the reaction cup 80.

[0122] It should be noted that the liquid level detection sensor in this application is a non-contact liquid level detection sensor, such as a photoelectric liquid level sensor or a capacitive liquid level sensor, etc.

This application preferably uses the columnar structure 3211 integrally formed with the detection bracket 321.

[0124] Preferably, such as Figure 4 As shown, the siphon tube 10 of this application has a liquid level indicator on its tube wall.

[0127] Preferably, as shown in Figure 4 , the liquid level mark comprises a first liquid level mark 13, which is arranged at the position of the lowest effective liquid level.

[0128] Exemplarily, a green line can be drawn at the position corresponding to the lowest effective liquid level on the outer wall of the siphon 10 to represent the first liquid level mark 13.

[0129] Preferably, as shown in Figure 4 , the liquid level mark comprises a second liquid level mark 14, which is arranged at the position of the highest allowable residual liquid level.

[0132] It should be noted that in actual application, the first sealing structure and the second sealing structure can be set as a structure in which a sealing ring cooperates with a sealing groove, or can be set as a structure in which a sealing gasket cooperates with a sealing gasket, or can be set as a structure in which a sealing sleeve cooperates with a sealing groove, and the like, and the adjustment and change of the specific structure form of the first sealing structure and the second sealing structure does not deviate from the principles and scope of the present application, and should be limited within the protection scope of the present application.

[0133] Preferably, as shown in Figure 4 , Figure 8 and Figure 9 , the sample filling mechanism 31 of the present application comprises a filling rubber plug 311, an air pipe 312 and a pressure pump 313, the filling rubber plug 311 has a hole 3111, the top end of the hole 3111 is communicated with the pressure pump 313 through the air pipe 312, and the bottom end of the hole 3111 is communicated with the siphon 10.

[0134] Exemplarily, the hole 3111 on the rubber plug 311 is arranged in a vertical direction, and the feeding device 20 can bring the siphon tube 10 into the hole 3111 from the bottom end of the hole 3111 to communicate the siphon tube 10 with the hole 3111 of the rubber plug 311.

[0135] The first sealing structure is a tapered hole 3112 formed at the bottom end of the hole 3111 on the rubber plug 311, and the second sealing structure is the rubber sleeve 12 arranged on the siphon tube 10, which is matched with the shape of the tapered hole 3112 to seal the bottom end of the hole 3111 after the top end of the siphon tube 10 is inserted into the hole 3111.

[0136] Specifically, the feeding mechanism inserts the siphon tube 10 into the hole 3111 from the bottom end of the rubber plug 311, and the rubber sleeve 12 arranged on the siphon tube 10 enters the tapered hole 3112 at the bottom end of the hole 3111, and the outer wall of the rubber sleeve 12 tightly fits on the inner wall of the tapered hole 3112 to seal the bottom end of the hole 3111 and prevent air leakage during the process of adding blood samples.

[0137] Preferably, as shown in Figure 4 The siphon tube 10 also has a minimum liquid level mark.

[0138] When the staff collects blood samples through the siphon tube 10, the minimum liquid level mark can be used to determine whether the amount of blood samples collected is sufficient. When the blood sample in the siphon tube 10 reaches the position of the minimum liquid level mark, there is no need to collect blood any more.

[0139] Preferably, as shown in Figure 4 The rubber sleeve 12 forms the minimum liquid level mark.

[0140] That is, the rubber sleeve 12 is installed at the position of the minimum liquid level mark, so that the rubber sleeve 12 itself also plays the role of the liquid level mark, and thus there is no need to separately set the minimum liquid level mark.

[0141] Preferably, as shown in Figure 4 The siphon tube 10 is provided with a resistance member 11, which divides the internal space of the siphon tube 10 into a first space and a second space, the first space is above the resistance member 11, and the second space is below the resistance member 11, the resistance member 11 is arranged to prevent the air in the first space from entering the second space to prevent the blood sample in the second space from dripping when no pressure is applied to the first space, and the resistance member 11 is also arranged to allow the air in the first space to enter the second space when pressure is applied to the first space.

[0142] The blood sample collected by the staff through the siphon tube 10 is all located in the second space of the siphon tube 10, and by arranging the resistance member 11 in the siphon tube 10, the blood sample in the siphon tube 10 can be prevented from leaking during the movement of the siphon tube 10 along with the feeding device 20. After the top of the siphon tube 10 is communicated with the hole 3111 of the filling rubber plug 311 of the sample filling mechanism 31, the sample filling mechanism 31 applies pressure to the first space, so that the air in the first space breaks through the resistance member 11 and enters the second space, thereby filling the blood sample in the second space into the reaction cup 80.

[0143] It should be noted that in actual application, the resistance member 11 can be arranged as resistance cotton or a microporous plug, and such adjustment and change of the specific structure type of the resistance member 11 do not deviate from the principles and scope of the present application, and should be limited within the protection scope of the present application.

The liquid inlet end of the reagent pump 43 is communicated with the reagent box 41, and the liquid outlet end of the reagent pump 43 is communicated with the reagent sample needle 42.

[0147] When it is needed to fill detection reagents into the reaction cup 80, the reagent pump 43 is started to pump the detection reagents in the reagent box 41 into the reagent sample needle 42, and then into the reaction cup 80. By arranging the reagent sample needle 42 obliquely, the influence on the image recognition device 110 when collecting images is small, thereby ensuring the accuracy of the detection results.

[0148] Preferably, the reagent pump 43 is a constant flow pump.

[0149] By adjusting the reagent pump 43, a specified amount of reagent (for example, 30-50 microliters) is pumped out per rotation, and the control is more convenient and accurate.

After the reaction cup 80 completely passes through the cup loading opening 622 and enters the loading cavity 621, the two vertical positioning ribs reset and abut against the outer side wall of one end of the reaction cup 80, while the other end of the reaction cup 80 abuts against the first inner side wall 6211 of the loading cavity 621, thereby achieving horizontal positioning of the reaction cup 80.
