Description

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 currently discovered blood type systems mainly include ABO blood type system, Rh blood type system, MNS blood type system, P blood type system and the like. 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, resulting in 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, resulting in poor user experience.

[0006] In a first aspect, the present application provides a blood type detector, comprising a housing and a consumable storage member, a shaking and mixing device and a loading and unloading device installed in the housing. The consumable storage member can store a plurality of reaction cups. The shaking and mixing device can carry the reaction cup and mix the blood sample added into the reaction cup with the detection reagent. The loading and unloading device can load the reaction cup located in the consumable storage member onto the shaking and mixing device and unload the reaction cup from the shaking and mixing device. Through such a setting, the detector of the present application can automatically realize the loading and unloading of the reaction cup, greatly improving the automation degree of the detector and providing better user experience.

[0007] In the preferred technical solution of the above blood type detector, the sample adding position and the reagent adding position of the blood type detector are spaced apart along the X direction. The blood type detector further comprises a translation device installed in the housing. The translation device can move the shaking and mixing device between the sample adding position and the reagent adding position. Through such a setting, the arrangement of each device is facilitated.

These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0048] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set," "connect," and "install" should be interpreted broadly, for example, referring to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0049] Specifically, this application provides a blood typing instrument, such as... Figure 1 and Figure 2 As shown, the blood typing instrument of this application includes a housing 100 and a feeding device 20 and a sample dispensing device 30 installed inside the housing 100.

[0050] The feeding device 20 can move the blood collection tube to connect it with the sample dispensing device 30, and the sample dispensing device 30 can dispense the blood sample from the blood collection tube into the reaction cup 80.

[0051] Specifically, after the blood sample is collected by 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 placement position to the sample injection position, and the top end of the blood collection tube is communicated with the sample injection device 30, and the sample injection device 30 applies pressure to the blood collection tube to inject the blood sample in the blood collection tube into the reaction cup 80 located at the sample injection position.

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

[0053] It should be noted that in actual application, 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 is not limited thereto. Of course, the present application preferably uses a siphon tube 10, which has a faster blood collection speed. The technical solution of the present application will be further introduced below by taking the blood collection tube as a siphon tube 10 as an example.

[0056] It should be noted that in actual application, the sample injection position and the reagent injection position can be arranged at the same position, in which case, after the blood sample in the siphon tube 10 is injected into the reaction cup 80, the reaction cup 80 does not need to be moved, and the detection reagent can be directly injected into the reaction cup 80 by the reagent injection device 40; or, the sample injection position and the reagent injection position can also be arranged separately, in which case, after the blood sample in the siphon tube 10 is injected into the reaction cup 80, the reaction cup 80 needs to be moved from the sample injection position to the reagent injection position first, and then the detection reagent is injected into the reaction cup 80 by the reagent injection device 40. This flexible adjustment and change deviating from the principle 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 an oscillation and mixing device 60 installed in the shell 100, and the oscillation and mixing device 60 can carry the reaction cup 80 and mix the blood sample and the detection reagent injected 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 mixing device 60 to mix the blood sample and the detection reagent filled into the reaction cup 80, so as to improve the accuracy of the detection result.

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

[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, and the like. 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 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 each label storage member 120 stores a blood type label of different type.

[0065] By providing 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 provides better user experience.

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

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

[0072] Preferably, as shown in 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 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, the loading and unloading device 70 can also be arranged to only be capable of loading the reaction cup 80 located in the consumable storage member 90 onto the oscillation and mixing device 60, or can also be arranged to only be capable of unloading the reaction cup 80 from the oscillation and mixing device 60 after the image recognition device 110 finishes collecting the image, and 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 present application preferably arranges the loading and unloading device 70 to be capable of both loading the reaction cup 80 located 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.

[0078] The present application separately arranges 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 siphon tube 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 located 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 present application comprises a feeding mechanism and a fixing mechanism 230 for carrying the siphon tube 10.

[0080] The feeding mechanism is capable of moving the fixing mechanism 230 and the siphon tube 10 fixed on the fixing mechanism 230 to make the siphon tube 10 communicate with the sample loading device 30, and is also capable of cooperating with the sample loading device 30 to unload the siphon tube 10 located 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.

[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.

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.

[0088] Specifically, when the siphon 10 needs to be unloaded, the columnar structure 3211 on the sample filling device 30 passes through the unloading through holes 2321 on the fixing mechanism 230, the front end (the left end of the columnar structure 3211 as viewed from above) of the columnar structure 3211 abuts against the siphon 10, the horizontal feeding mechanism 210 continuously moves the siphon 10 towards the columnar structure 3211, the columnar structure 3211 pushes the siphon 10 out of the fixing through holes 23121 from the unloading openings 23122 on the fixing mechanism 230, and the unloading of the siphon 10 is completed. After being extruded by the siphon 10, the unloading openings 23122 have a larger opening size, so that the siphon 10 can be smoothly pushed out. Figure 8

[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 rack, etc. Such adjustment and change of the specific structure form 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 form 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, detects 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.

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 with 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.

[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 filling the blood sample.

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

[0138] When the staff collects the blood sample through the siphon tube 10, the minimum liquid level mark can be used to determine whether the amount of the collected blood sample is sufficient. When the blood sample in the siphon tube 10 reaches the position of the minimum liquid level mark, it is not necessary 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 it is not necessary to separately set the minimum liquid level mark.

[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 into 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 does 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.

The cup carrier 62 has a cup-filling port 622 on the side near the consumable storage component 90. After the loading component 72 pushes the reaction cup 80 out of the cup outlet 901 of the consumable storage component 90, the reaction cup 80 enters the mounting chamber 621 of the cup carrier 62 through the cup-filling port 622.

[0170] In other words, the cup carrier 62 is provided with a cup loading port 622 and a cup unloading port 623 on two opposite sides. After the image recognition device 110 has acquired the image, the loading and unloading drive mechanism 71 drives the unloading component 73 to move horizontally toward the cup carrier 62. The unloading component 73 enters the loading chamber 621 from the cup unloading port 623 and pushes the reaction cup 80 out from the cup loading port 622, unloading the reaction cup 80 from the cup carrier 62 of the oscillating mixing device 60.

In this case, in order to smoothly move the reaction cups 80 in the storage chamber towards the bottom end of the storage chamber, a pushing member (such as a spring) can be arranged at the top end of the storage chamber. When the reaction cup 80 at the bottom of the storage chamber is pushed out, the remaining reaction cups 80 move towards the bottom end of the storage chamber under the action of the pushing member.

The cup loading member 62 is made of plastic material, and when the reaction cup 80 is loaded, the two vertical positioning ribs are extruded by the reaction cup 80, and the distance between them increases. 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.
