Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an auxiliary blood sampling device and an operating method thereof. Background Art

[0002] In the medical field, medical staff can collect information such as clinical physiological and pathological parameters of the human body through various testing methods for disease diagnosis. Among them, the collection of blood samples is one of the more important ways to obtain information.

[0003] In the traditional blood collection process, the blood collection tube is picked up by the person waiting for blood collection, and then the medical staff affixes labels to each blood collection tube and completes the disinfection and puncture of the needle insertion site. When collecting blood, the medical staff needs to constantly change the blood collection tube and shake the blood collection tube containing anticoagulant. The entire blood collection operation process is relatively complicated, the labor intensity of medical staff is relatively high, and it is easy to make mistakes.

[0004] Therefore, how to provide a solution to overcome or alleviate the above-mentioned defects is still a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0005] The purpose of the present invention is to provide an auxiliary blood collection device and an operating method thereof, which can reduce the labor intensity of medical personnel when performing blood collection operations, relieve the fatigue of medical personnel, and thus reduce the possibility of errors.

[0006] To solve the above technical problems, the present invention provides an auxiliary blood collection device, comprising: a blood collection box; a test tube table, which can be located in the blood collection box, the test tube table comprising a test tube rack and a driving component, the test tube rack is provided with at least two installation positions, each of which is used to accommodate a blood collection test tube, the driving component is connected to the test tube rack, and is used to drive the test tube rack to move; a labeling unit, which is arranged in the blood collection box, and is used to affix an identification label to the blood collection test tube; a first action unit, which is arranged in the blood collection box, comprises a first clamping assembly, a second clamping assembly, a first driving assembly and a second driving assembly, the first clamping assembly is used to clamp the blood collection test tube, the second clamping assembly is used to clamp the blood collection needle assembly, the first driving assembly is connected to the first clamping assembly, and is used to drive the first clamping assembly to move, The second driving assembly is connected to the second clamping assembly, and is used to drive the second clamping assembly to move so as to control the blood collection needle assembly to be inserted into or out of the blood collection tube; the second action unit is arranged in the blood collection box, and includes a third clamping assembly and a third driving assembly. The third clamping assembly is also used to clamp the blood collection tube. The third driving assembly is connected to the third clamping assembly, and is used to drive the blood collection tube to be transferred between the test tube table and the labeling unit, and is used to shake the blood collection tube; the visual detection unit is arranged in the blood collection box, and is at least used to visually detect the test tube table, the blood collection tube and the blood collection needle assembly; the control unit is communicatively connected to the driving component, the labeling unit, the first action unit, the second action unit and the visual detection unit.

[0007] When the auxiliary blood collection device is in use, the first clamping assembly of the first action unit can clamp the blood collection tube in the test tube table, the second clamping assembly can clamp the blood collection needle assembly, and the second driving assembly can drive the second clamping assembly to move to control the blood collection needle assembly to insert or detach from the blood collection tube, thereby completing automatic blood collection in the blood collection tube. In addition, the driving component can also drive the test tube rack of the test tube table to move, so as to switch the blood collection tubes in different installation positions to cooperate with the first action unit, and blood can be collected in different blood collection tubes one by one, which can meet the actual needs of the person waiting for blood collection to collect multiple tubes of blood.

[0008] Furthermore, after the blood sampling tube has completed blood sampling, the third clamping assembly of the second action unit can clamp the blood sampling tube that has completed blood sampling, and the third driving assembly can drive the third clamping assembly, so that the blood sampling tube that has completed blood sampling can be transferred to the labeling unit for affixing of an identification label, thereby adding an identity mark to the blood sampling tube that has completed blood sampling, so as to establish an accurate association between the blood sampling tube and the person to be blood sampled, and avoid errors in blood testing to a large extent. At the same time, for blood sampling tubes containing anticoagulants, the third driving assembly can also synchronously shake the blood sampling tube during the process of transferring the blood sampling tube, which can effectively promote the uniform mixing of the anticoagulant and the blood sample.

[0009] In this way, when medical staff use the auxiliary blood collection equipment provided by the embodiment of the present invention to perform blood collection operations, they only need to operate the blood collection needle assembly to disinfect and puncture the needle insertion site of the person to be blood drawn. Other operations such as operating the blood collection needle assembly to insert the blood collection tube, replacing the blood collection tube, shaking the blood collection tube, and adding identification labels to the blood collection tube can all be completed automatically by the auxiliary blood collection equipment, which can greatly reduce the labor intensity of medical staff, alleviate the fatigue of medical staff, and thus reduce the number of errors.

[0099] Embodiment 1

[0100] Please refer to Figure 1-Figure 5 , Figure 1 It is a structural schematic diagram of the auxiliary blood sampling device provided by an embodiment of the present invention, wherein the drawer unit is inserted into the blood sampling box; Figure 2 This is a schematic diagram of the structure of the auxiliary blood sampling device provided by an embodiment of the present invention, wherein the drawer unit is pulled out from the blood sampling box, and the control unit and the visual detection unit are omitted; Figure 3 is a structural schematic diagram of a drawer unit; Figure 4 It is a schematic diagram of the structure of the test tube rack; Figure 5 for Figure 1 A partial enlarged view of the first storage area in FIG.

[0101] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an auxiliary blood collection device, including a blood collection box 1000, a test tube table 2100, a labeling unit 3000, a first action unit 4000 and a second action unit 5000.

[0102] The blood collection box 1000 is the external structure of the auxiliary blood collection device, and other unit modules can be directly or indirectly installed on the blood collection box 1000 so as to be integrated and assembled through the blood collection box 1000. At the same time, the structural shape of the blood collection box 1000 also basically determines the appearance contour shape of the auxiliary blood collection device provided by the embodiment of the present invention. In practical applications, those skilled in the art can adjust the structural shape of the blood collection box 1000 according to specific needs. For example, the blood collection box 1000 can be a rectangular parallelepiped. For another example, in the implementation method of the attached drawings, as shown in FIG. Figure 1 and Figure 2 As shown, from a top view, the blood collection box 1000 can be roughly L-shaped.

[0103] The blood collection box 1000 may include a box body and a top cover. The top cover may be mounted on the box body, and the specific mounting method may be, for example, screw connection, riveting, clamping, etc., which is not limited here. It should be understood that Figure 1 and Figure 2 The figure shows the structure of the blood collection box 1000 after removing the top cover.

[0104] The test tube stand 2100 includes a test tube rack 2110 and a driving component 2120. The test tube rack 2110 is provided with at least two mounting positions 2110A, each of which is used to hold a blood collection test tube A1. The driving component 2120 is connected to the test tube rack 2110 and is used to drive the test tube rack 2110 to move, so that the blood collection test tubes A1 in different mounting positions 2110A can be easily switched for use.

[0105] Here, the embodiment of the present invention does not limit the specific arrangement of the installation positions 2110A in the test tube table 2100, nor does it limit the specific structural form of the driving component 2120. In practical applications, those skilled in the art can make a selection according to specific needs, as long as it can meet the requirements of use. It should be understood that the arrangement of the installation positions 2110A in the test tube table 2100 and the structural form of the driving component 2120 are related.

[0106] In an exemplary embodiment, Figure 3 and Figure 4 As shown, each installation position 2110A can be arranged at intervals along the circumference of the test tube table 2100. At this time, the driving component 2120 can be a driving component in the form of a motor, a rotary cylinder, etc., so as to provide a rotational driving force to the test tube table 2100 to drive the test tube table 2100 to rotate and displace around its own axis P, so that the blood collection test tube A1 at different installation positions 2110A in the circumferential direction can be conveniently switched for use. In this process, the position of the test tube table 2100 as a whole in the blood collection box 1000 does not change, and the space occupied by it in the blood collection box 1000 does not change. In other words, the space required for the installation and use of the test tube table 2100 in the blood collection box 1000 can be relatively small, which is also conducive to realizing the miniaturization design of the blood collection box 1000 (that is, the auxiliary blood collection device provided by the embodiment of the present invention).

[0107] In this scheme, if Figure 4As shown, the test tube stand 2100 may include a well plate 2111 and a base 2112. The well plate 2111 may be mounted on the base 2112. The specific mounting method may be, for example, welding, screw connection, clamping, riveting, etc., as long as the reliability requirements of the connection can be guaranteed. The well plate 2111 may be provided with an insertion hole 2111A, and the base 2112 may be provided with an insertion slot 2112A. The number of the insertion holes 2111A and the number of the insertion slots 2112A are at least two, and the number of the insertion holes 2111A and the number of the insertion slots 2112A may be equal. Each insertion hole 2111A and each insertion slot 2112A may be arranged one by one in the circumferential direction. An insertion hole 2111A and an insertion slot 2112A corresponding to each other in the circumferential direction may be combined to form a mounting position 2110A. During specific installation, the blood sampling tube A1 can first pass through the insertion hole 2111A and then be assembled in the insertion groove 2112A. In this way, the installation reliability of the blood sampling tube A1 can be improved.

[0108] It should be understood that, in addition to the above description, in some other designs of the embodiments of the present invention, the test tube table 2100 may also adopt other structural forms, as long as it can meet the requirements of use. For example, the number of the orifice plates 2111 may be at least two, and each orifice plate 2111 may be arranged at intervals along the axial direction of the test tube table 2100. For another example, the test tube table 2100 may also include only the base 2112, that is, the installation position 2110A may also include only the insertion groove 2112A. In this case, by controlling the depth of the insertion groove 2112A, etc., the reliable installation of the blood collection test tube A1 can also be guaranteed.

[0109] In another exemplary solution, each installation position 2110A can be arranged in sequence along a straight line direction. In this case, the driving component 2120 needs to output a straight line displacement.

[0110] In practical applications, the driving component 2120 can be a linear driving element that can directly output linear displacement, such as a linear cylinder or a linear oil cylinder. In this case, the driving component 2120 can have relatively few parts and a relatively simple structure. Alternatively, the driving component 2120 can also be a rotary driving element in the form of a motor or a rotary cylinder. In this case, a displacement conversion mechanism in the form of a gear rack mechanism or a lead screw mechanism is required to convert the rotary displacement directly output by the rotary driving element into the required linear displacement.

[0111] The labeling unit 3000 is disposed in the blood collection box 1000 and is used to attach identification labels to the blood collection tubes A1.

[0112] It should be noted that the specific structural form of the labeling unit 3000 is relatively mature in the relevant technology, so it will not be described in detail here. In actual application, those skilled in the art can refer to the relevant technology for selection and determination. In addition, different people who need blood collection require different identification labels according to their actual blood collection information. These identification labels can be directly printed in the labeling unit 3000; that is, the label roll of the labeling unit stores blank labels. In actual application, according to the different people who need blood collection, the actual blood collection information, etc., the QR code and other identification information can be printed in real time in the blank label to obtain the identification label, and then the identification label is pasted.

[0113] The first action unit 4000 is also disposed in the blood collection box 1000 , and includes a first clamping assembly 4100 , a second clamping assembly 4200 , a first driving assembly 4300 and a second driving assembly 4400 .

[0114] The first clamping assembly 4100 is used to clamp the blood collection tube A1. The second clamping assembly 4200 is used to clamp the blood collection needle assembly 9000. The first driving assembly 4300 is connected to the first clamping assembly 4100, and is used to drive the first clamping assembly 4100 to move, so as to adjust the position of the first clamping assembly 4100 in the blood collection box 1000. The second driving assembly 4400 is connected to the second clamping assembly 4200, and is used to drive the second clamping assembly 4200 to move, so as to adjust the position of the second clamping assembly 4200 in the blood collection box 1000, and can control the blood collection needle assembly 9000 to be inserted into the blood collection tube A1, or control the blood collection needle assembly 9000 to be separated from the blood collection tube A1.

[0115] The second action unit 5000 is also disposed in the blood collection box 1000 , and includes a third clamping assembly 5100 and a third driving assembly 5200 .

[0116] The third clamping assembly 5100 is also used to clamp the blood collection tube A1. The third driving assembly 5200 is connected to the third clamping assembly 5100 and is used to drive the third clamping assembly 5100 to move so as to adjust the position of the third clamping assembly 5100 in the blood collection box 1000, so as to at least drive the blood collection tube A1 to be transferred between the test tube table 2100 and the labeling unit 3000, and at least to shake the blood collection tube A1.

[0117] By adopting the above scheme, when the auxiliary blood collection device provided by the embodiment of the present invention is in use, the first clamping assembly 4100 of the first action unit 4000 can clamp the blood collection tube A1 in the test tube table 2100, the second clamping assembly 4200 can clamp the blood collection needle assembly 9000, and the second driving assembly 4400 can drive the second clamping assembly 4200 to move to control the blood collection needle assembly 9000 to insert or detach from the blood collection tube A1, so as to complete the automatic blood collection in the blood collection tube A1. In addition, the driving component 2120 can also drive the test tube rack 2110 of the test tube table 2100 to move, so as to switch the blood collection tube A1 in different installation positions 2110A to cooperate with the first action unit 4000, and blood can be collected in different blood collection tubes A1 one by one, which can meet the actual needs of the person waiting for blood collection to collect multiple tubes of blood.

[0118] Furthermore, after the blood sampling tube A1 has completed blood sampling, the third clamping assembly 5100 of the second action unit 5000 can clamp the blood sampling tube A1 that has completed blood sampling, and the third driving assembly 5200 can drive the third clamping assembly 5100, so that the blood sampling tube A1 that has completed blood sampling can be transferred to the labeling unit 3000 for affixing of an identification label, thereby adding an identity mark to the blood sampling tube A1 that has completed blood sampling, so as to establish an accurate association between the blood sampling tube A1 and the person to be blood sampled, thereby avoiding errors in blood testing to a large extent. At the same time, for the blood sampling tube A1 containing an anticoagulant, the third driving assembly 5200 can also synchronously shake the blood sampling tube A1 during the process of transferring the blood sampling tube A1, which can effectively promote the uniform mixing of the anticoagulant and the blood sample.

[0119] In this way, when medical staff use the auxiliary blood collection equipment provided by the embodiment of the present invention to perform blood collection operations, they only need to operate the blood collection needle assembly 9000 to disinfect and puncture the needle insertion site of the person to be blood drawn. Other operations such as operating the blood collection needle assembly 9000 to insert the blood collection tube A1, replacing the blood collection tube A1, shaking the blood collection tube A1, and adding an identification label to the blood collection tube A1 can all be completed automatically by the auxiliary blood collection equipment, which can greatly reduce the labor intensity of medical staff, alleviate the fatigue of medical staff, and thus reduce the number of errors.

[0120] It should be understood that the blood collection tube A1 in the embodiment of the present invention includes a test tube body A11 and a test tube cap A12. One end of the test tube body A11 may have an opening, and the test tube cap A12 may be installed on the test tube body A11 to seal the opening. Moreover, the blood collection tube A1 may also be a negative pressure tube. When the blood collection needle assembly 9000 is inserted into the blood collection tube A1, blood may automatically flow into the blood collection tube A1 to automatically complete blood collection, thereby improving the convenience of blood collection. Based on this, the process of inserting the blood collection needle assembly 9000 into the blood collection tube A1 is actually the process of the blood collection needle assembly 9000 passing through the test tube cap A12 and partially extending into the test tube body A11.

[0121] Still Figure 1 As shown, the auxiliary blood sampling device provided in the embodiment of the present invention also includes a visual detection unit 6000 and a control unit 7000.

[0122] The visual inspection unit 6000 includes at least one camera, which can be disposed in the blood collection box 1000, for example, can be disposed on the top cover. The visual inspection unit 6000 is at least used to visually inspect the aforementioned test tube table 2100, the blood collection test tube A1, and the blood collection needle assembly 9000, so as to guide the first action unit 4000 to clamp the blood collection test tube A1, the blood collection needle assembly 9000, etc., which is conducive to improving the action reliability of the first action unit 4000.

[0123] The control unit 7000 may also be disposed in the blood collection box 1000, or the control unit 7000 may also be disposed independently of the blood collection box 1000, which is not limited here. The control unit 7000 may be connected to the aforementioned driving component 2120, the labeling unit 3000, the first action unit 4000, the second action unit 5000, and the visual detection unit 6000 for communication, so as to control the action process of these components.

[0124] In some optional implementations, the auxiliary blood collection device provided by the embodiments of the present invention may further include a drawer unit 2000 .

[0125] like Figure 3 As shown, the drawer unit 2000 may include a drawer component 2200 and a test tube stand 2100. The specific structural form of the drawer component 2200 may refer to various drawer structures presented in the relevant art, and is not explicitly limited here. The drawer component 2200 may be slidably connected to the blood collection box 1000 so as to pull out ( Figure 2 ), or pushed into the blood collection box 1000 (as shown Figure 1 The test tube stand 2100 can be installed on the drawer component 2200 and can be synchronously moved in and out of the blood collection box 1000 with the drawer component 2200.

[0126] In specific use, the medical staff can first pull the drawer unit 2000 out of the blood collection box 1000, and then pre-select and configure the blood collection test tubes A1 required by the blood collection personnel according to the actual blood collection information of the blood collection personnel, and then put them one by one into the test tube table 2100, so that the medical staff can push the drawer unit 2200 together with the test tube table 2100 into the blood collection box 1000 to perform the blood collection operation. After the blood collection operation is completed, the medical staff can pull the drawer unit 2000 out of the blood collection box 1000, and the medical staff can recover the blood collection test tubes A1 that have completed blood collection, and then send them for inspection to complete the detection of the blood sample.

[0127] In this implementation, for each person who needs blood collection, the medical staff needs to configure the blood collection tube A1 according to the actual blood collection information and place it on the test tube table 2100; after completing the blood collection, each blood collection tube A1 also needs to be removed from the test tube table 2100 in a timely manner to vacate the test tube table 2100 to avoid affecting the next blood collection operation. The blood collection tube A1 will not be retained at any position in the blood collection box 1000. Accordingly, there is no need to reserve a storage space for the blood collection tube A1 in the blood collection box 1000. The volume of the blood collection box 1000 can be relatively small, that is, the volume of the auxiliary blood collection device provided by the embodiment of the present invention can be relatively small, and the installation space occupied in actual use can be relatively small, so as to facilitate use.

[0128] For the convenience of distinction and explanation, the embodiment of the present invention refers to the above-mentioned blood collection mode as a self-matching mode.

[0129] Based on this mode, the auxiliary blood collection device provided in the embodiment of the present invention may also be configured with a scanning unit (not shown in the figure), and the scanning unit may also be connected to the control unit 7000 for communication. The scanning unit may be installed in the blood collection box 1000, and is used to scan the blood collection mark containing the actual blood collection information, so as to obtain the required actual blood collection information. The above-mentioned blood collection mark may be, for example, a QR code information, etc., which may be reflected in the blood collection document of the person to be blood-collected, so that the medical staff may directly scan and obtain it.

[0130] Here, the embodiment of the present invention does not limit the specific structural form of the above-mentioned scanning unit. In practical applications, those skilled in the art can make a selection based on relevant technologies and specific needs, as long as it can meet the requirements of use.

[0131] It should be understood that the actual blood collection information can also be obtained in other links, for example, when the blood collection personnel are performing relevant registration in blood collection places such as hospitals or physical examination institutions, or when selecting physical examination packages. At this time, the actual blood collection information can be synchronized by personnel or equipment (such as computers) in other links to the medical staff who directly perform the blood collection operation, or to the control unit 7000 of the auxiliary blood collection device provided in the embodiment of the present invention, without the need for the medical staff who directly perform the blood collection operation to re-scan and obtain the information. Accordingly, the auxiliary blood collection device provided in the embodiment of the present invention does not need to be provided with the above-mentioned scanning unit, and can also simplify the structure of the auxiliary blood collection device provided in the embodiment of the present invention to reduce costs.

[0132] In some optional implementations, such as Figure 1 and Figure 2 As shown, a first storage area 1100 and a second storage area 1200 may also be provided in the blood collection box 1000. The first storage area 1100 is used to store empty blood collection tubes A1. The second storage area 1200 is used to store blood collection tubes A1 after blood collection. The first storage area 1100 and the second storage area 1200 may be arranged at different positions in the blood collection box 1000, respectively.

[0133] In this implementation, the second action unit 500 is also used to take out the blood collection tube A1 from the first storage area 1100 and put the blood collection tube A1 into the second storage area 1200.

[0134] Before starting blood collection, the control unit 7000 can control the second action unit 5000 to select a suitable blood collection test tube A1 in the first storage area 1100 according to the actual blood collection information obtained (which can be directly scanned or transmitted from equipment in other links), and transport it to the installation position 2110A of the test tube table 2100 for the first action unit 4000 to control the blood collection. The selection of the blood collection test tube A1 can be carried out with the assistance of the visual inspection unit 6000. In this way, the accuracy of the selection of the blood collection test tube A1 can also be guaranteed.

[0135] It should be known that different types of blood collection tubes A1 used for different detection purposes often have different appearances, such as the color, size, shape, etc. of the tube cap A12. Therefore, with the assistance of the visual detection unit 6000, the control unit 7000 can drive the second action unit 5000 to accurately select the blood collection tube A1 in the first storage area 1100 in combination with the actual blood collection information.

[0136] When the actual blood collection information corresponds to at least two blood collection test tubes A1, all the blood collection test tubes A1 may be moved to the test tube table 2100 before starting blood collection.

[0137] When a blood sampling tube A1 has completed blood sampling, the control unit 7000 can also control the second action unit 5000 to transfer the blood sampling tube A1 that has completed blood sampling to the labeling unit 3000 for affixing an identification label. The blood sampling tube A1 that needs to be shaken should also be shaken synchronously. Afterwards, the control unit 7000 can also control the second action unit 5000 to transfer the blood sampling tube A1 to the second storage area 1200 for storage.

[0138] By adopting the above scheme, when the embodiment of the present invention is conducting blood collection for blood collection personnel, it is not necessary for the medical staff to manually configure the blood collection tube A1 each time. Instead, the control unit 7000, the first action unit 4000, and the second action unit 5000 can cooperate to automatically select the blood collection tube A1 in the first storage area 1100 and place the blood collection tube A1 that has been completed in the second storage area 1200. The automation level is high, which can further reduce the labor intensity of the medical staff; at the same time, the accuracy can also be high, which can reduce the situation where the blood collection tube A1 is selected incorrectly due to human errors. In addition, the implementation of the above scheme can also reduce the number of times the blood collection box 100 is opened, which is conducive to improving the airtightness of the blood collection box 1000 during use, which has positive significance for ensuring the cleanliness of the blood collection box 1000, reducing cross infection during blood collection, ensuring the cleanliness of blood samples, and the accuracy of subsequent blood sample testing.

[0139] For the convenience of distinction and explanation, the embodiment of the present invention refers to the above-mentioned blood sampling mode as a self-selection mode.

[0140] In practical applications, both the self-selection mode and the self-matching mode can exist in the auxiliary blood collection device provided by the embodiment of the present invention. The self-selection mode can be used as a general mode, so that the auxiliary blood collection device can automatically cooperate with the medical staff to complete the blood collection, so that the entire auxiliary blood collection device can have a high degree of automation. The self-matching mode can be used as a special mode. If the actual blood collection information contains special requirements and the corresponding blood collection tube A1 is not stored in the first storage area 1100, the medical staff can select and configure the blood collection tube A1 required by the blood collection personnel separately, so as to meet the special blood collection requirements in a targeted manner.

[0141] Through the coordination of the self-selection mode and the self-matching mode, the application scenarios and applicable scope of the auxiliary blood collection device provided by the embodiment of the present invention can be broadened to a greater extent, which is conducive to the promotion and application of the auxiliary blood collection device.

[0142] Here, the embodiment of the present invention does not limit the specific structural form of the first storage area 1100 and the second storage area 1200. In practical applications, those skilled in the art can make a selection according to specific needs, as long as it can meet the needs of use. It should be understood that the structural form of the first storage area 1100 and the second storage area 1200 can be basically the same. Therefore, the following embodiment of the present invention is mainly described with respect to the first storage area 1100, and the second storage area 1200 will not be described separately.

[0143] like Figure 5 As shown, the first storage area 1100 may be provided with a storage mechanism 1110. The storage mechanism 1110 may include a storage rack 1111 and an elastic member 1112.

[0144] The storage rack 1111 may be provided with a storage channel 1111A, and the blood collection tube A1 may be located in the storage channel 1111A. The elastic component 1112 may also be located in the storage channel 1111A, and is used to abut against the blood collection tube A1 to elastically fix the blood collection tube A1, thereby improving the stability of the blood collection tube A1 placed in the storage rack 1111.

[0145] In practical applications, the number of storage channels 1111A may be at least two, wherein each storage channel 1111A may contain one type of blood collection tube A1, and different types of blood collection tubes A1 may be placed in different storage channels 1111A. In this way, mixing and wrong selection of blood collection tubes A1 can be avoided to a large extent.

[0146] The at least two storage channels 1111A mentioned above may be formed in the same storage rack 1111. Alternatively, at least two storage mechanisms 1110 may be provided in the first storage area 1100, and the storage racks 1111 of each storage mechanism 1110 may form a storage channel 1111A separately, so that the at least two storage channels 1111A mentioned above can be formed in the first storage area 1100. Alternatively, at least two first storage areas 1100 may be provided in the blood collection box 1000, so that at least two storage channels 1111A can be formed.

[0147] Here, the embodiment of the present invention does not limit the specific type of the elastic component 1112. In practical applications, those skilled in the art can select according to specific needs, as long as it can meet the requirements of use. For example, the elastic component 1112 can be a linear spring. There are many types and models of linear springs, and they have better elastic deformation ability, which can better meet the application requirements of the embodiment of the present invention. For another example, the elastic component 1112 can also be an elastomer made of materials such as rubber, latex, and silicone that have a certain elastic deformation ability. In this way, it can also meet the technical requirements for elastic fixation of the blood sampling tube A1.

[0148] During the specific operation, if the vacant blood collection tubes A1 in the first storage area 1100 have been taken out, or the number is less than the set value, or the number of a certain type of blood collection tubes A1 is too small, the medical staff can open the blood collection box 1000 to replenish the blood collection tubes A1 in the first storage area 1100. Similarly, if the blood collection tubes A1 that have completed blood collection in the second storage area 1200 are full or about to be full, the medical staff can also open the blood collection box 1000 and then take out the blood collection tubes A1 that have completed blood collection in the second storage area 1200 to empty the second storage area 1200.

[0149] In some optional implementations, such as Figure 1 As shown, the auxiliary blood collection device provided in the embodiment of the present invention may further include a human-machine interaction unit 8000. The human-machine interaction unit 8000 may be installed in the blood collection box 1000 and may be in communication connection with the control unit 7000.

[0150] The structural form of the human-computer interaction unit 8000 can be diverse, and is not explicitly limited here. It needs to be determined in combination with actual usage requirements. For example, the human-computer interaction unit 8000 may include a display module to display the working status, working progress, etc. of the auxiliary blood collection device provided by the embodiment of the present invention, such as whether there is a shortage of blood collection tubes A1 in the first storage area 1100, whether the blood collection tubes A1 in the second storage area 1200 are full, whether the blood collection process is completed, whether there is an operating error, etc. The display module may specifically include a display screen, a signal indicator light, etc. For another example, the human-computer interaction unit 8000 may also include some control buttons, through which corresponding control can be applied to the auxiliary blood collection device; it should be understood that the control button can be a physical button or a virtual button, and the virtual button specifically refers to a virtual button directly displayed on the display screen (the display screen needs to be a touch screen). For another example, the human-computer interaction unit 8000 may also include a voice module, which can receive voice commands from medical staff. At the same time, it can also inform medical staff of the working status, working progress, etc. of the aforementioned auxiliary blood collection equipment through voice broadcasting, so that the medical staff can carry out subsequent operations in a timely manner.

[0151] In conclusion, by configuring the human-computer interaction unit 8000, the interactivity and ease of use of the auxiliary blood collection device provided by the embodiment of the present invention can be greatly improved.

[0152] Please refer to Figure 6-Figure 12 , Figure 6 It is a relative position diagram of the first action unit and the drawer unit in the blood collection box; Figure 7 is a structural schematic diagram of the first action unit; Figure 8 It is a connection structure diagram of the position adjustment component, the first driving assembly and the first clamping assembly in the first action unit; Fig. 9 It is a structural diagram of the installation of the second driving assembly and the second clamping assembly on the first driving seat; Fig.10 is a relative position diagram of the first action unit and the drawer unit, wherein the first action unit has not yet clamped the blood collection tube; Fig.11 is a relative position diagram of the first action unit and the drawer unit, wherein the first action unit has completed clamping the blood collection tube; Fig.12 The structure diagram of the control unit and the visual detection unit assisting the first action unit in completing the connection between the blood collection needle assembly and the blood collection tube Figure 1

[0153] like Figure 6-Figure 9 As shown, in the embodiment of the present invention, the first driving assembly 4300 may include a first driving member 4310 and a first driving seat 4320 .

[0154] The first driving member 4310 is a power component, which can be connected to the first driving seat 4320 to drive the first driving seat 4320 to perform linear displacement. The first clamping assembly 4100 can specifically be an electric clamp, a pneumatic clamp, etc. In short, as long as the first clamping assembly 4100 can achieve the functions of clamping and releasing. The first clamping assembly 4100 may include two first clamps, and the clamped object may be located between the two first clamps. The first clamping assembly 4100 may be installed on the first driving seat 4320, and the installation method includes but is not limited to welding, bonding, screw connection, etc.

[0155] With this solution, when the first driving member 4310 is started, it can drive the first driving seat 4320 to move, and further drive the first clamping assembly 4100 to move, so as to complete the driving of the first clamping assembly 4100.

[0156] The first driving member 4310 may be a linear driving element that can directly output linear displacement, such as a linear cylinder or a linear oil cylinder. In this way, the number of parts required for the first driving member 4310 may be relatively small, and the structure may be relatively simple. Alternatively, the first driving member 4310 may also be a rotary driving element that can directly output rotational displacement, such as a motor. In this case, the first driving assembly 4300 may also include a displacement conversion mechanism in the form of a gear rack mechanism, a screw mechanism, etc., so as to convert the rotational displacement directly output by the rotary driving element into a linear displacement.

[0157] In the implementation of the accompanying drawings, Figure 8 As shown, the first driving assembly 4300 may further include a driving screw 4330. The first driving member 4310 may specifically be a motor, which may be connected to the driving screw 4330 to drive the driving screw 4330 to rotate. The first driving seat 4320 is equivalent to a screw nut, which may be threadedly connected to the driving screw 4330. In this way, when the driving screw 4330 rotates, the first driving seat 4320 may be linearly displaced along the driving screw 4330 to drive the first clamping assembly 4100 to be linearly displaced.

[0158] Further, the first action unit 4000 may further include a base 4500, and the first driving assembly 4300 may further include a first guide rail 4340. The first driving member 4310 and the first guide rail 4340 may both be mounted on the base 4500. The first driving seat 4320 may be slidably connected to the first guide rail 4340 to improve the displacement reliability and directionality of the first driving seat 4320.

[0159] In the embodiment of the present invention, the second driving assembly 4400 may include a second driving member 4410 and a second driving seat 4420 .

[0160] The second driving member 4410 is a power component, which may be installed on the aforementioned first driving seat 4320. The second driving seat 4420 may be slidably connected to the first driving seat 4320. The second driving member 4410 may be connected to the second driving seat 4420, and is used to drive the second driving seat 4420 to perform linear displacement. The second clamping assembly 4200 may specifically be an electric clamp, a pneumatic clamp, etc. In short, as long as the second clamping assembly 4200 can achieve the functions of clamping and releasing. The second clamping assembly 4200 may include two second clamps, and the clamped object may be located between the two second clamps. The second clamping assembly 4200 may be installed on the second driving seat 4420, and the installation method includes but is not limited to welding, bonding, screw connection, etc.

[0161] With this solution, when the second driving member 4410 is started, it can drive the second driving seat 4420 to move, and further drive the second clamping assembly 4200 to move, so as to complete the driving of the second clamping assembly 4200.

[0162] The specific structural form of the second driving member 4410 may be consistent with the aforementioned first driving member 4310, and a repeated description thereof will not be given here.

[0163] In the implementation of the accompanying drawings, Fig. 9 As shown, the second driving member 4410 can be a motor. The second driving assembly 4400 can also include a driving gear 4430 and a driving rack 4440. The motor can be connected to the driving gear 4430 to drive the driving gear 4430 to rotate. The driving rack 4440 can be connected to the second driving seat 4420, and the driving rack 4440 can be meshed with the driving gear 4430. In this way, when the driving gear 4430 rotates, the driving rack 4440 can drive the second driving seat 4420 and the second clamping assembly 4200 to perform linear displacement.

[0164] Further, the second driving assembly 4400 may further include a second guide rail 4450. The second guide rail 4450 may be mounted on the first driving seat 4320. The second driving seat 4420 may be slidably connected to the second guide rail 4450, so as to improve the displacement reliability and directionality of the first driving seat 4320.

[0165] Here, the embodiment of the present invention does not limit the specific displacement direction of the first clamping assembly 4100 and the second clamping assembly 4200. In practical applications, those skilled in the art can select according to specific needs as long as they can meet the requirements of use. Figure 6-Figure 9As shown, the first clamping assembly 4100 and the second clamping assembly 4200 can be displaced in the same direction, which is defined as a third direction Z in the embodiment of the present invention. The third direction Z can specifically be a vertical direction, that is, an up and down direction, the axial direction of the blood collection tube A1, etc.

[0166] In an embodiment of the present invention, the first action unit 4000 may further include a position adjustment component 4600. The position adjustment component 4600 may be connected to the base 4500 to drive the base 4500 to move in the blood collection box 1000, that is, it may drive the aforementioned first clamping component 4100, the second clamping component 4200, the first drive component 4300 and the second drive component 4400 to move in the blood collection box 1000, thereby improving the movement range of the first clamping component 4100 and the second clamping component 4200 in the blood collection box 1000 to a greater extent.

[0167] like Figure 6-Figure 11 As shown, the position adjustment assembly 4600 may include a first adjustment component 4610 and a second adjustment component 4620 .

[0168] The first adjustment component 4610 can be installed on the bottom wall of the blood collection box 1000, the second adjustment component 4620 can be installed on the first adjustment component 4610, and the base 4500 can be installed on the second adjustment component 4620. The first adjustment component 4610 is used to drive the second adjustment component 4620 to move along the first direction X. The second adjustment component 4620 is used to drive the base 4500 to move along the second direction Y. The first direction X and the second direction Y can be set at an angle, and the angle can be, for example, 90 degrees. In this way, the position adjustment component 4600 is a dual-degree-of-freedom adjustment component, which can realize the degree of freedom adjustment of the base 4500 in the first direction X and the second direction Y.

[0169] In combination with the aforementioned first clamping assembly 4100 and the second clamping assembly 4200, they can be displaced along the third direction Z, that is, the first action unit 4000 in the embodiment of the present invention can realize the displacement of the first clamping assembly 4100 and the second clamping assembly 4200 in three directions, which can better meet the requirements of use.

[0170] Combination Figure 6 and Figure 7The first adjustment component 4610 may include a first adjustment track 4611, which may extend along the first direction X and may be installed on the bottom wall of the blood collection box 1000. The second adjustment component 4620 may include a second adjustment track 4621, which may extend along the second direction Y and may be slidably connected to the first adjustment track 4611, and the base 4500 may be slidably connected to the second adjustment track 4621.

[0171] In specific applications, the first adjustment member 4610 and the second adjustment member 4620 may include a driving member to provide the driving force required for displacement. The specific structural form of the driving member can refer to the above description of the first driving member 4310 and the second driving member 4410, and a repeated description is not given here.

[0172] Combination Figure 10-12 In the actual blood collection process, the control unit 7000 and the visual detection unit 6000 can be used in conjunction to guide the second clamping assembly 4200 to complete the clamping of the blood collection needle assembly 9000. Then, the position of the first clamping assembly 4100 in the blood collection box 1000 can be adjusted by the position adjustment assembly 4600, so that the first clamping assembly 4100 can be relatively close to the test tube table 2100. Then, the first clamping assembly 4100 can clamp the blood collection tube A1, and the first clamping assembly 4100 and the second clamping assembly 4200 can cooperate to complete the blood collection operation in the blood collection tube A1.

[0173] It should be understood that the above description of the specific structural form of the first action unit 4000 is only a combination of the embodiments of the present invention. Figure 6-Figure 11 The exemplary descriptions made cannot be used as a limitation on the scope of implementation of the auxiliary blood collection device provided by the embodiment of the present invention. Under the condition of satisfying the functions, the first action unit 4000 may also adopt other structural forms. For example, the second drive assembly 4400 may not be installed on the first drive seat 4320, but may be directly installed on the base 4500. In this case, the first drive assembly 4300 and the second drive assembly 4400 may be independent of each other. For another example, the position adjustment assembly 4600 may not be set. In this case, the first clamping assembly 4100 and the second clamping assembly 4200 may only have the degree of freedom adjustment in one direction. For another example, the position adjustment assembly 4600 may also include only one of the first adjustment component 4610 and the second adjustment component 4620. In this case, the first clamping assembly 4100 and the second clamping assembly 4200 may only have the degree of freedom adjustment in two directions.

[0174] Please refer to Figure 13-Figure 16 , Fig.13is a connection structure diagram of the second action unit and the blood collection tube; Fig.14 A schematic diagram of the structure of the second action unit in the auxiliary blood sampling device provided in an embodiment of the present invention clamping the blood sampling tube at the test tube table; Fig.15 This is a structural schematic diagram of the second action unit in the auxiliary blood sampling device provided in an embodiment of the present invention shaking the blood sampling tube; Fig.16 This is a structural schematic diagram of the second action unit in the auxiliary blood collection device provided by an embodiment of the present invention picking up a blood collection tube from the first storage area.

[0175] like Fig.13 As shown, the third driving assembly 5200 may include a third driving member 5210 , a third driving seat 5220 and a multi-degree-of-freedom robotic arm 5230 .

[0176] The third driving member 5210 is a power component, which can be connected to the third driving seat 5220, and is used to drive the third driving seat 5220 to perform linear displacement. The specific displacement direction can also be the aforementioned third direction Z, so as to adjust the installation height of the third driving seat 5220. The structure of the third driving member 5210 can be consistent with that of the first driving member 4310. For details, please refer to the aforementioned description, and no repetitive description is given here. In the implementation method of the attached drawings, as shown in FIG. Fig.13 As shown, the third driving assembly 5200 may further include a third guide rail 5250 , and the third driving seat 5220 may be slidably connected to the third guide rail 5250 , so as to improve the displacement reliability and directionality of the third driving seat 5220 .

[0177] Furthermore, the third driving assembly 5200 may also include a third adjustment rail 5240 and an adapter seat 5260 .

[0178] The third adjustment track 5240 may be fixedly arranged, and specifically may be fixedly connected to the inner wall surface of the blood collection box 1000. Fig.13 In the implementation manner, the extension direction of the third adjustment track 5240 can be the first direction X, of course, it can also be the second direction Y or other directions, and no clear limitation is made here.

[0179] The adapter 5260 can be installed on the third adjustment track 5240 and can slide along the third adjustment track 5240. The third guide rail 5250 and the third driving member 5210 can be installed on the adapter 5260 so as to move along the third adjustment track 5240 driven by the adapter 5260, thereby increasing the adjustment freedom of the second action unit 5000.

[0180] In actual applications, the second action unit 5000 can also be provided with a fourth driving member (not shown in the figure), and the structural form of the fourth driving member can be consistent with the third driving member 5210, which can be directly or indirectly connected to the adapter seat 5260 to provide driving force, thereby driving the adapter seat 5260 to move along the third adjustment track 5240.

[0181] The multi-degree-of-freedom robot arm 5230 may be a six-axis robot arm, etc., one end of which may be connected to the third drive seat 5220, and the other end of which may be connected to the third clamping assembly 5100. The third clamping assembly 5100 may be an electric clamp, a pneumatic clamp, etc. In short, as long as the third clamping assembly 5100 can realize the functions of clamping and releasing.

[0182] In actual application, the third driving member 5210, the fourth driving member and the multi-degree-of-freedom robot arm 5230 can all be activated to adjust the position and posture of the blood collection tube A1 in the blood collection box 1000, so as to complete the driving of the blood collection tube A1. The second action unit 5000 driving the blood collection tube A1 may include picking up the blood collection tube A1 (such as Fig.16 ), the blood collection tube A1 is transferred from the first storage area 1100 to the tube table 2100 (as shown in FIG. Figure 1 - as shown), the blood collection tube A1 is transferred from the test tube table 2100 to the labeling unit 3000 for affixing the identification label and shaking the blood collection tube A1 (as shown in FIG. Fig.15 As shown), and the blood collection tube A1 with the identification label affixed is transferred to the test tube table 2100 (in the self-matching mode), or transferred to the second storage area 1200 (in the self-selection mode).

[0183] It should be understood that the above description of the specific structural form of the second action unit 5000 is only a combination of the embodiments of the present invention. Fig.13 The exemplary descriptions made cannot be used as limitations on the scope of implementation of the auxiliary blood collection device provided by the embodiment of the present invention. Under the condition of satisfying the functions, the second action unit 5000 may also adopt other structural forms. For example, the second action unit 5000 may only include a multi-degree-of-freedom mechanical arm 5230. For another example, the second action unit 5000 may not be provided with a fourth drive member, a third adjustment track 5240, and an adapter 5260. For another example, the second action unit 5000 may not be provided with a third drive member 5210 and a third drive seat 5220. In this case, the multi-degree-of-freedom mechanical arm 5230 may be directly mounted on the adapter 5260.

[0184] Please refer to Fig.17 and Fig.18 , Fig.17 It is a structural schematic diagram of a blood collection needle assembly; Fig.18 It is a connection structure diagram of the hose section, the clamping section and the puncture section.

[0185] like Fig.17 As shown, in an embodiment of the present invention, the blood collection needle assembly 9000 may include a needle 9100 , a hose segment 9200 , a clamping segment 9300 and a puncturing segment 9400 .

[0186] The two ends of the hose section 9200 can be connected to the needle 9100 and the clamping section 9300 respectively. The needle 9100 is used to directly pierce the body of the person to be blood drawn. The clamping section 9300 is used to clamp the second clamping assembly 4200. Therefore, the overall hardness of the clamping section 9300 is higher than that of the hose section 9200, so as to reliably clamp the second clamping assembly 4200. The end of the clamping section 9300 away from the hose section 9200 can be connected to the puncturing section 9400, and the puncturing section 9400 is used to be inserted into the test tube cap A12.

[0187] In practical applications, the blood collection needle assembly 9000 may further include a sealing cap 9500, which may be placed over the puncture section 9400 to protect the puncture section 9400. When blood collection is required, the sealing cap 9500 may be removed first to expose the puncture section 9400, and then the puncture section 9400 and the test tube cap A12 may be connected.

[0188] The sealing cap 9500 can be manually removed by medical personnel outside the blood collection box 1000. Alternatively, it can be automatically removed by the first action unit 4000. In this case, a receiving component (not shown) can be provided in the blood collection box 1000 to collect the sealing cap 9500 removed by the first action unit 4000.

[0189] A flow velocity detection component 9330 is provided in the clamping section 9300. The flow velocity detection component 9330 is used to detect the real-time flow velocity v of blood in the clamping section 9300.

[0190] It should be understood that for a specific blood collection needle assembly 9000, the inner diameter of the clamping section 9300 is determined, and accordingly, the flow area s of the clamping section 9300 is determined. Then, by monitoring the real-time flow time t of blood in the clamping section 9300, the real-time blood volume V flowing through the clamping section 9300 can be measured. In practical applications, the real-time blood volume V can be compared with the set blood volume to control the blood collection end point of the blood collection tube A1.

[0191] When the real-time blood volume reaches the set blood volume, the control unit 7000 can pull the puncture section 9400 out of the blood collection tube A1 through the second clamping assembly 4200, which can prevent excessive blood from entering the blood collection tube A1, and accordingly, can reduce the waste of blood from the person waiting for blood collection, and can reduce harm to the patient. At the same time, it can also avoid the situation where the amount of blood entering the blood collection tube A1 is too small, resulting in the inability to perform the test.

[0192] For a person who is waiting for blood collection, when all the blood collection tubes A1 that meet their actual blood collection information have completed blood collection, the human-machine interaction unit 8000 of the auxiliary blood collection device in the embodiment of the present invention can send out an indication signal of blood collection completion, so that the medical staff can pull out the needle 9100. In the case where there are multiple blood collection tubes A1, when any of the blood collection tubes A1 has completed blood collection, the human-machine interaction unit 8000 can send out an indication signal, so that the medical staff can accurately grasp the progress of the blood collection operation.

[0193] In the embodiment of the present invention, Fig.18 As shown, the clamping section 9300 may include an inner tube portion 9310 and an outer clamping portion 9320, the outer clamping portion 9320 may be located radially outside the inner tube portion 9310, and the aforementioned second clamping assembly 4200 may specifically clamp the outer clamping portion 9320. The flow velocity detection component 9330 may include a first ultrasonic sensor 9331 and a second ultrasonic sensor 9332, the first ultrasonic sensor 9331 and the second ultrasonic sensor 9332 may be located on both radial sides of the inner tube portion 9310, respectively. The central axis of the first ultrasonic sensor 9331 and the central axis of the second ultrasonic sensor 9332 may be arranged at an angle φ to the central axis of the inner tube portion 9310, and the spacing between the first ultrasonic sensor 9331 and the second ultrasonic sensor 9332 is l.

[0194] With this solution, the ultrasonic signal of the first ultrasonic sensor 9331 can be received by the second ultrasonic sensor 9332, and the first propagation time of the ultrasonic signal is The ultrasonic signal of the second ultrasonic sensor 9332 can be received by the first ultrasonic sensor 9331, and the second propagation time of the ultrasonic signal Among them, C f is the propagation speed of the ultrasonic signal in the static blood, which is a constant. The first propagation time T1 and the second propagation time T2 can be directly measured. Thus, by combining and transforming the above two formulas, the real-time flow rate of the blood in the clamping section 9300 can be obtained.

[0195] Through the cooperation of the first ultrasonic sensor 9331 and the second ultrasonic sensor 9332, and the detection of the first propagation time T1 and the second propagation time T2, the measurement error of the real-time flow velocity v can be reduced, thereby improving the measurement accuracy of the real-time flow velocity v.

[0196] It should be understood that the above description of the specific structural form of the flow velocity detection component 9330 is only a combination of the embodiments of the present invention. Fig.18 The exemplary description provided here is not intended to limit the scope of implementation of the auxiliary blood sampling device provided by the embodiment of the present invention. Under the condition that the functions are met, those skilled in the art may also select other types of flow velocity detection components 9330. For example, the flow velocity detection component 9330 may also include only one ultrasonic sensor, which may include a transmitting end and a receiving end, which may be respectively arranged on both radial sides of the inner tube 9310, and the central axis of the transmitting end and the receiving end may form the aforementioned angle φ with the central axis of the inner tube 9310, so that the real-time flow velocity v of the blood can also be measured.

[0197] In addition, in the above-mentioned solution description, the clamping section 9300 is a split structure, including an inner tube portion 9310 and an outer clamping portion 9320 which are separately arranged, and the outer clamping portion 9320 needs to be connected to the inner tube portion 9310 by interference fit, bonding, etc. In some other implementations of the embodiments of the present invention, the clamping section 9300 can also be directly set as an integrated structure, which will not affect the measurement of the real-time flow velocity v.

[0198] Embodiment 2

[0199] Please refer to Figure 19-22 , Fig.19 A schematic flow chart of an operation method of the auxiliary blood sampling device provided in an embodiment of the present invention; Fig. 20 A schematic diagram of the flow of blood sampling mode information and judgment in the operation method of the auxiliary blood sampling device provided in an embodiment of the present invention; Fig.21 is a flowchart of step S400 and step S500 when the blood sampling mode information is self-matching information; Fig. 22 It is a flowchart of step S400 and step S600 when the blood sampling mode information is self-selected information.

[0200] like Fig.19 As shown, an embodiment of the present invention further provides an operating method of an auxiliary blood sampling device, which can be applied to the auxiliary blood sampling devices involved in each implementation manner in Example 1. The operating method at least includes the following steps S100 to S400.

[0201] Step S100, obtaining actual blood sampling information.

[0202] As mentioned above, the actual blood collection information can be obtained by scanning the blood collection mark in the blood collection document of the person to be blooded by the medical staff through the scanning unit at the auxiliary blood collection device provided in the embodiment of the present invention. Alternatively, it can also be obtained in other links, for example, it can be obtained when the person to be blooded registers in a blood collection place such as a hospital or a physical examination institution, or when the person to be blooded selects a physical examination package, etc.

[0203] Step S200, configuring the test tube module A on the test tube table 2100 according to the actual blood collection information.

[0204] Step S300 , controlling the first action unit 4000 to complete blood collection in the blood collection tube A1 on the test tube table 2100 .

[0205] Specifically, step S300 may include: controlling the first clamping assembly 4100 to clamp the blood collection tube A1; applying a driving force through the second driving member 4410 to control the second clamping assembly 4200 to drive the puncture section 9400 of the blood collection needle assembly 9000 to insert into the blood collection tube A1; after completing blood collection in the blood collection tube A1, the blood collection needle assembly 9000 can be pulled out of the blood collection tube A1 through the second clamping assembly 4200.

[0206] The test tube module A may include only one blood collection test tube A1, or the test tube module A may include at least two blood collection test tubes A1, which is specifically related to the actual blood collection information. When the test tube module A includes multiple blood collection test tubes A1, the above step S300 may also include a test tube switching step, which may be specifically driven by the driving component 2120 to drive the test tube rack 2110 so as to switch different blood collection test tubes A1 for blood collection.

[0207] Step S400, controlling the second action unit 5000 to send the blood collection tube A1 after blood collection to the labeling unit 3000 for affixing of an identification label, and shaking the blood collection tube A1 that needs to be shaken.

[0208] By adopting this scheme, the embodiment of the present invention can control the first clamping component 4100 and the second clamping component 4200 to automatically operate according to the actual blood collection information of the person to be blood-collected through the implementation of steps S100 to S300, so as to complete the automatic clamping of the blood collection tube A1, the automatic insertion of the puncture section 9400 into the blood collection tube A1, and the automatic extraction of the puncture section 9400 from the blood collection tube A1, thereby automatically achieving blood collection from the blood collection tube A1. After the blood collection is completed, through the implementation of step S400, the identification label can be attached to the blood collection tube A1 and shaken through the second action unit 5000.

[0209] In this way, when drawing blood, medical staff only need to operate the blood collection needle assembly 9000 to disinfect and puncture the needle insertion site of the person to be blood drawn. Other operations such as inserting the blood collection needle assembly 9000 into the blood collection tube A1, replacing the blood collection tube A1, shaking the blood collection tube A1, and adding an identification label to the blood collection tube A1 can all be automatically completed by the auxiliary blood collection equipment provided by the embodiment of the present invention, which can greatly reduce the labor intensity of medical staff, alleviate the fatigue of medical staff, and thus reduce the number of errors.

[0210] In some optional implementations, such as Fig. 20 As shown, the operating method provided in the embodiment of the present invention may further include step S110 and step S120 between step S100 and step S200.

[0211] Step S110, obtaining blood sampling mode information.

[0212] The blood sampling mode information may be input by medical personnel themselves, or may be obtained by the control unit 7000 according to actual blood sampling information. The blood sampling mode information may include a self-matching mode and a self-selecting mode.

[0213] Step S120, determining whether the blood sampling mode information is a self-matching mode or a self-selected mode.

[0214] When the blood collection mode information is the self-matching mode, the above step S200 may be: the medical staff configures the test tube module A on the test tube table 2100 according to the actual blood collection information. Specifically, the above step S200 may include: pulling the drawer unit 2000 out of the blood collection box 1000; the medical staff pre-selects and configures the blood collection test tubes A1 required by the blood collection personnel according to the actual blood collection information, and then puts them into the test tube table 2100 one by one; and pushing the drawer unit 2200 together with the test tube table 2100 into the blood collection box 1000.

[0215] At this time, if Fig.21 As shown, the operation method provided by the embodiment of the present invention may further include, after step S400: step S500, controlling the second action unit 5000 to place the blood collection test tube A1 after the identification label is attached to the test tube table 2100 again, so as to collect the blood collection test tube A1. After all the blood collection test tubes A1 are placed on the test tube table 2100, the medical staff can pull the drawer unit 200 out of the blood collection box 1000 again to empty the test tube table 2100, so as to facilitate the implementation of the subsequent blood collection operation without affecting the continuity of the operation.

[0216] When the blood sampling mode information is the self-selection mode, step S200 may be: controlling the second action unit 5000 to select the corresponding blood sampling test tube A1 in the first storage area 1100 according to the actual blood sampling information, and arranging it on the test tube table 2100 to form the test tube module A. Fig. 22 As shown, the operation method provided by the embodiment of the present invention may further include, after step S400: step S600, controlling the second action unit 5000 to place the blood collection tube A1 with the identification label attached thereto in the second storage area 1200 for storage.

[0217] In specific implementation, the self-selection mode can be used as a general mode, so that the auxiliary blood collection equipment can automatically cooperate with medical staff to complete blood collection, so that the operation method of the entire auxiliary blood collection equipment can have a high degree of automation. At the same time, it can also reduce the errors caused by human operation, and it is also beneficial to improve accuracy. The self-matching mode can be used as a special mode. When the actual blood collection information contains special requirements and the corresponding blood collection tube A1 is not stored in the first storage area 1100, the medical staff can select and configure the blood collection tube A1 required by the blood collector separately, so as to meet the special blood collection requirements in a targeted manner. In the embodiment of the present invention, through the cooperation of the self-selection mode and the self-matching mode, the use scenario of the auxiliary blood collection equipment provided by the embodiment of the present invention can be broadened to a greater extent, which is conducive to the promotion and application of the auxiliary blood collection equipment.

[0218] Please refer to Fig.23 , Fig.23 A schematic flow chart of the operation method of the auxiliary blood sampling device provided in an embodiment of the present invention when performing real-time pattern information detection.

[0219] In some optional implementations, such as Fig.23 As shown, the operating method provided in the embodiment of the present invention may further include the following steps S210 to S240 between step S200 and step S300.

[0220] Step S210, obtaining real-time pattern information of the test tube module A. Step S210 may be specifically obtained by the aforementioned visual inspection unit 6000. The real-time pattern information at least includes pattern information of the test tube cap A12 of the blood collection test tube A1 of the test tube module A.

[0221] Step S220, analyzing the real-time pattern information to generate theoretical blood sampling information.

[0222] Step S230, compare the theoretical blood sampling information and the actual blood sampling information to see if they are consistent, if not, execute the following step S240.

[0223] Step S240, outputting alarm information.

[0224] As described in part of the embodiment, different models of blood collection tubes A1 used for different detection purposes are often different in appearance, for example, the color, size, shape, etc. of the test tube cap A12 will show differences. Therefore, the real-time pattern information of the test tube module A obtained in step S210 should be able to reflect the quantity information and type information of the blood collection test tubes A1 included in the test tube module A. By analyzing the real-time pattern information, theoretical blood collection information can be obtained.

[0225] Under normal circumstances, the theoretical blood collection information and the actual blood collection information should be consistent, which means that the test tube module A configured at the test tube table 2100 is accurate.

[0226] However, due to the intervention of various unexpected factors such as human operation errors and system errors, there may be discrepancies between the theoretical blood collection information and the actual blood collection information. In this case, the auxiliary blood collection device provided by the embodiment of the present invention can also output alarm information in a timely manner to remind medical staff of errors. Medical staff can manually check the test tube module A etc. output from the test tube table 2100 in a timely manner, which can largely avoid the occurrence of more serious blood collection errors, thereby improving the accuracy of the auxiliary blood collection device provided by the embodiment of the present invention in assisting blood collection operations.

[0227] Here, the embodiment of the present invention does not limit the specific type of the above-mentioned alarm information. In practical applications, those skilled in the art can select according to specific needs, as long as it can meet the requirements of use. For example, the alarm information can be a voice message, such as "Error! Error!", etc., which is issued by the voice module at the aforementioned human-computer interaction unit 8000. For another example, the alarm information can be a text message, etc., which can be displayed by the display module at the aforementioned human-computer interaction unit 8000. For another example, the alarm information can also be a light signal, such as a red light signal, which is issued by the signal indicator light at the aforementioned human-computer interaction unit 8000.

[0228] In addition, the embodiment of the present invention does not limit the specific analysis process of step S220, which is actually an image processing step. By extracting and identifying identification features such as the test tube cap A12 in the image, theoretical blood collection information can be easily obtained through real-time pattern information.

[0229] Please refer to Figure 2 , Fig.24 The present invention is a flowchart of the method for operating the auxiliary blood sampling device provided in an embodiment of the present invention when removing the sealing cap.

[0230] In some optional implementations, such as Figure 2-, the operating method of the auxiliary blood collection device provided in the embodiment of the present invention may further include the following steps S031 to S040 before step S300, so as to achieve the clamping of the clamping section 9300 of the blood collection needle assembly 9000 by the second clamping assembly 4200 and the removal of the sealing cap 9500. Fig.17 The blood collection needle assembly 9000 may include a hose segment 9200. When performing a blood collection operation, part of the hose segment 9200 may be located in the blood collection box 1000. In an embodiment of the present invention, the part of the hose segment 9200 located in the blood collection box 1000 may be referred to as an in-box tube segment.

[0231] Step S031, obtaining image information of the tube section in the blood collection box 1000. Step S031 may specifically be obtained by the aforementioned visual detection unit 6000.

[0232] Step S032, obtaining the coordinate information of the tube section in the blood collection box 1000 according to the image information.

[0233] Step S033, according to the coordinate information, the first action unit 4000 is moved so that the pipe section in the box can be located between the two first clamping jaws of the first clamping assembly 4100, and the pipe section in the box can be located between the two second clamping jaws of the second clamping assembly 4200. At this time, there can be a set gap between the first clamping assembly 4100 and the second clamping assembly 4200, and the set gap specifically refers to the gap between the two clamping assemblies along the third direction Z.

[0234] Step S034, control the distance between the two first jaws to be adjusted to the first distance, so that the pipe section in the box can slide between the two first jaws, and the two first jaws can form a stop for the clamping section 9300; control the distance between the two second jaws to be adjusted to the second distance, so that the two second jaws can clamp the pipe section in the box.

[0235] After step S034 is executed, the second clamping assembly 4200 can clamp the pipe section in the box, while the first clamping assembly 4100 does not clamp the pipe section in the box, so that the pipe section in the box can still slide between the two first clamping jaws of the first clamping assembly 4100. At the same time, the first distance between the two first clamping jaws is not too large, and the two first clamping jaws can still stop the clamping section 9300, so that the clamping section 9300 does not pass directly between the two first clamping jaws.

[0236] Step S035, control the second clamping assembly 4200 to drive the tube section in the box to move away from the first clamping assembly 4100, and the moving distance is less than or equal to the first set distance. The specific value of the first set distance can be determined as needed and is not explicitly limited here.

[0237] Step S036, determining whether the first clamping jaw is in contact with the clamping section 9300, if not, executing the following step S037, if so, executing the following step S039.

[0238] The specific judgment method can be whether the second clamping assembly 4200 encounters resistance in the process of driving the pipe section in the box to move. If resistance is encountered, resulting in the pipe section in the box being basically unable to be pulled, it means that the first clamping jaw has abutted against the clamping section 9300. If no resistance is encountered, it means that the first clamping jaw is not abutted against the clamping section 9300.

[0239] Step S037, the distance between the two first clamping jaws is adjusted to the second distance, so that the two first clamping jaws can clamp the pipe section in the box, and the distance between the two second clamping jaws is adjusted to the first distance, so that the pipe section in the box can slide between the two second clamping jaws. At this time, the second clamping assembly 4200 can release the pipe section in the box, and the first clamping assembly 4100 can clamp the pipe section in the box, so as to prevent the pipe section in the box from falling.

[0240] Step S038, controlling the second clamping assembly 4200 to move toward the first clamping assembly 4100 until the distance between the first clamping assembly 4100 and the second clamping assembly 4200 is restored to the aforementioned set gap, and then repeating steps S034 and S036.

[0241] Step S039, the distance between the two first clamping jaws is controlled to be adjusted to a third distance, so that the clamping section 9300 and the sealing cap 9500 can slide between the two first clamping jaws, the first clamping assembly 4100 is controlled to move a second set distance away from the second clamping assembly 4200, so that the sealing cap 9500 can be located between the two first clamping jaws, and then the two first clamping jaws are controlled to clamp the sealing cap 9500. It should be understood that the second distance < the first distance < the third distance.

[0242] Step S040, controls the distance between the two second clamping jaws to be adjusted to a third distance, and controls the second clamping assembly 4200 to move the third set distance toward the first clamping assembly 4100, so that the clamping section 9300 can be located between the two second clamping jaws, and then controls the two second clamping jaws to clamp the clamping section 9300, and then controls the first clamping assembly 4100 to move away from the second clamping assembly 4200 to pull the sealing cap 9500 off the puncture section 9400.

[0243] With such configuration, through the implementation of the aforementioned steps S031 to S040, the operation method provided in the embodiment of the present invention can realize the automatic clamping of the clamping section 9300 by the second clamping assembly 4200, and the automatic removal of the sealing cap 9500. In actual application, medical staff only need to put part of the blood collection needle assembly 9000 (including the puncture section 9400 and the sealing cap 9500) into the blood collection box 1000, and the first action unit 4000 can automatically complete the clamping and fixing of the clamping section 9300 of the blood collection needle assembly 9000 and the removal of the sealing cap 9500 under the assistance and control of the control unit 7000 and the visual detection unit 6000, which can greatly improve the automation degree of the auxiliary blood collection device provided in the embodiment of the present invention, thereby improving the convenience of operation.

[0244] Please refer to Fig.25 , Fig.25 This is a flow chart of the operation method of the auxiliary blood sampling device provided in an embodiment of the present invention when performing real-time blood volume detection.

[0245] In some optional implementations, such as Fig.25 As shown, step S300 of the operating method provided in the embodiment of the present invention may also include steps S310 to S350.

[0246] Step S310, controlling the flow velocity detection component 9330 to obtain the real-time flow velocity v of the blood in the clamping section 9300. The specific acquisition method can refer to the description of a part of the above embodiment, and will not be repeated here.

[0247] Step S320, obtaining the actual circulation time t of blood in the clamping section 9300.

[0248] It should be understood that in the two scenarios where blood does not flow in the clamping section 9300 and blood flows in the clamping section 9300, the propagation speed of the ultrasonic signal in the clamping section 9300 is different; combined with the above-mentioned embodiment 1, that is, the first propagation time T1 and the second propagation time T2 are different. Therefore, by detecting the propagation time of the ultrasonic signal, it is possible to determine whether blood flows, that is, to obtain the above-mentioned actual circulation time t.

[0249] Step S330, calculating the real-time blood volume flowing through the clamping section 9300 according to the formula V=tvs, wherein s is the flow area of ​​the clamping section 9300, and V is the real-time blood volume.

[0250] Step S340, determining whether the real-time blood volume reaches the set blood volume, if so, executing the following step S350.

[0251] Step S350, controlling the second clamping assembly 4200 to pull the puncturing section 9400 out of the blood collection tube A1.

[0252] With such a configuration, through the implementation of the aforementioned steps S310 to S350, the real-time blood flow rate flowing into the blood collection tube A1 can be accurately determined, and the puncture section 9400 can be promptly pulled out to control the amount of blood entering the blood collection tube A1, which can largely avoid the situation of excessive blood collection, reduce the waste of blood of the person waiting for blood collection, and reduce the harm to the patient. At the same time, it can also avoid too little blood entering the blood collection tube A1, and thus affect the subsequent blood sample detection.

[0253] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
