[0032] Obviously, the described embodiments are only part of the embodiments of the present application, not all embodiments, based on the embodiments of the present application, other embodiments obtained by the person skilled in the art without creative labor are all within the scope of protection of the present application. The technical features in the present application can be combined interactively without mutual contradiction and conflict.

[0033] It can be understood that after blood collection, a barcode is generally pasted on the blood bag, and each blood bag is numbered through the barcode, so as to facilitate subsequent storage and management.

[0034] Referring to Figures 1 to 6 The embodiment of the present application provides a multifunctional blood weight management instrument, which has a weighing function and can identify the barcode information pasted on the blood bag, so that an operator can more conveniently record the weight of the blood bag corresponding to the barcode information, reduces the situation that the barcode information does not correspond to the weighing result, and can improve the efficiency of blood weighing management.

[0035] In the embodiment, the multifunctional blood weight management instrument comprises a weighing table 100, a camera 200, a barcode recognition module and a display screen 300. The weighing table 100 comprises a placing table 110 and a weighing sensor 120. The placing table 110 is used for placing a blood bag, and the blood bag is used for containing blood. The lower end of the placing table 110 is connected with the weighing sensor 120, and the weighing sensor 120 can obtain the weight of the blood in the blood bag.

[0036] It can be understood that the weighing sensor 120 is electrically connected with the display screen 300. The multifunctional blood weight management instrument is provided with a controller. When the weighing sensor 120 obtains the weight of the blood, the controller controls the display screen 300 to display the weight of the blood. The operator can intuitively know the weight of the blood in the blood bag, so as to facilitate subsequent recording and management. The controller can be a single-chip microcomputer, a PLC controller or the like. As long as the controller can realize the function of controlling the display screen 300 to display, it is acceptable.

[0037] The barcode recognition module is in communication connection with the camera 200 and is electrically connected with the display screen 300. After the image information obtained by the camera 200 is transmitted to the barcode recognition module, the barcode recognition module can recognize the barcode appearing in the image information and convert the barcode into a digital number, which is the barcode information. The display screen 300 displays the obtained barcode information, so that the operator can intuitively know the barcode information and record the blood in the blood bag.

[0038] It can be understood that the barcode recognized by the barcode recognition module can be a one-dimensional barcode or a two-dimensional barcode.

[0039] Since the display screen 300 can display the weight of the blood in the blood bag placed on the placing table 110 and the barcode information corresponding to the blood bag at the same time, the situation that the blood weight does not correspond to the barcode can be avoided, the manual error is reduced, and the accuracy of blood management is improved.

[0040] In some embodiments, the multifunctional blood weight management instrument further comprises a specification classification module. The specification classification module is electrically connected with the weighing sensor 120. The specification classification module can judge the specification of the blood bag according to the weight of the blood obtained by the weighing sensor 120 and classify and identify the specification of the blood bag.

[0041] It can be understood that the blood product loaded in the blood bag has multiple specifications, and each specification corresponds to a different blood weight range, so as to realize the conversion between the blood weight and the blood volume specification. For example, different blood bags are divided into 100ml, 200ml, 400ml and the like, or are divided into large, medium and small specifications.

[0042] In some embodiments, the multifunctional blood weight management instrument further comprises a color recognition module, which is in communication connection with the camera 200, and the camera 200 is arranged towards the upper surface of the placing table 110, which can collect the image information of the blood bag and transmit the image information to the color recognition module, and the color recognition module obtains the blood color information in the blood bag according to the obtained image information of the blood bag, instead of manually identifying the color of the blood.

[0043] When the color recognition module obtains the blood color information, the controller controls the display screen 300 to display the blood color information, so that the operator can intuitively know the color information of the blood in the blood bag, so as to facilitate subsequent recording and management, and can accurately judge whether the blood is qualified.

[0044] It can be understood that the qualified blood color is generally bright red or dark red. The color of abnormal blood is different from that of normal blood, for example, the color of fatty blood is usually milky white. In this embodiment, the color recognition module converts the blood color in the image information obtained by the camera 200 into digital code by using the RGB color standard, which has higher color recognition accuracy than the naked eye. It can be understood that the color recognition module can also use CMYK mode or Lab mode or a combination of multiple color modes.

[0045] In some embodiments, the multifunctional blood weight management instrument further comprises a comparison module for comparing color information, which is in electrical connection with the color recognition module, and can automatically compare the blood color information recognized by the color recognition module with the preset color data range, such as comparing the RGB data corresponding to the obtained blood color with the preset RGB data range. When the RGB data obtained by the color recognition module is within the preset range, it is considered that the recognized blood color is qualified, otherwise it is considered that the blood color is unqualified.

[0046] In some embodiments, the comparison module is in electrical connection with the display screen 300, and the comparison result of the comparison module can be displayed on the display screen 300. When the comparison module judges that the blood color is qualified, the controller controls the display screen 300 to display the word "qualified"; when the comparison module judges that the blood color is unqualified, the controller controls the display screen 300 to display the word "unqualified". In this way, the operator can intuitively know the condition of the blood without manually comparing the data, which greatly improves the accuracy and efficiency, and timely removes the unqualified blood sample for subsequent management and use.

[0047] In some embodiments, whether the blood is qualified or not is prompted by different color lights. For example, when the comparison module judges that the blood color is qualified, the controller controls the display screen 300 to display green light; when the comparison module judges that the blood color is unqualified, the controller controls the display screen 300 to display red light.

[0048] In some embodiments, the multifunctional blood weight management instrument further comprises an alarm module, which is used to issue an alarm, and is electrically connected with the comparison module.

[0049] It can be understood that the alarm module can realize the alarm through sound, vibration, warning light and the like, so as to attract the attention of the operator.

The color recognition module recognizes the blood color information in the image information collected by each collection area, and obtains the blood color information in the blood bag on each placing table 110 according to the image information collected by each collection area, to assist in judging whether the blood in each blood bag is qualified.

[0051] In this way, after the blood bag is placed on one of the weighing tables 100, the operator can place another blood bag on another weighing table 100 during the process of camera 200 collection, color recognition module recognition, barcode recognition module recognition and comparison module comparison. This can greatly improve the blood weighing management efficiency and reduce the blood identification recording time.

[0052] In this embodiment, the weighing table 100 is provided with six, and the six weighing tables 100 are divided into two rows in front and back, and three weighing tables 100 are arranged in each row along the left-right direction.
