[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail below.

[0025] Example: This application proposes an RFID blood management system, referring to... Figure 1-3 The main body of the management system includes a blood sample box 1, a sample refrigerator 2, an radio frequency scanning mechanism 3, a control host 4, and an out-of-warehouse auxiliary mechanism 5.

[0026] In this embodiment, the blood samples are packaged in blood bags with RFID tags affixed to them. The blood sample box 1 is a rectangular transparent plastic box, and each blood sample box 1 holds one or more blood samples of the same blood type for easy retrieval.

[0027] The sample refrigerator 2 is a long and narrow cabinet with several rows of placement compartments 21 on its upper side. The openings of the placement compartments 21 face upwards and are used to place blood sample boxes 1. The blood sample boxes 1 are placed from top to bottom into the placement compartments 21 and are flush with the upper side of the sample refrigerator 2. The sample refrigerator 2 is covered with an insulation cover to keep the temperature of the sample refrigerator 2 constant.

[0028] The radio frequency scanning mechanism 3 is installed above the sample refrigerator 2. It can be set inside the insulation cover or outside the insulation cover. In this embodiment, it is set inside the insulation cover. The radio frequency scanning mechanism 3 is used to perform radio frequency scanning on the blood samples in each placement compartment 21 and obtain blood sample information, and at the same time feed it back to the control host 4.

[0029] The radio frequency scanning mechanism 3 includes a moving track 31, a radio frequency scanning reader 32, a moving vehicle body 33, and a drive motor 34. The axial direction of the moving track 31 is parallel to the length direction of the sample refrigerator 2. The moving vehicle body 33 is movably mounted on the moving track 31. The radio frequency scanning reader 32 is mounted on the moving vehicle body 33 and moves together with the moving vehicle body 33. The drive motor 34 is also mounted on the moving vehicle body 33 and drives the moving vehicle body 33 to move. The drive motor 34 is electrically connected to the control host 4 and is controlled by the control host 4 to start and stop.

[0030] For example, the moving track 31 is set as a linear guide rail, with both ends fixedly connected to the two ends of the sample refrigerator 2, so that the moving track 31 and the sample refrigerator 2 maintain a distance of 10cm; the moving vehicle 33 reciprocates on the moving track 31, and the drive motor 34 is a servo motor, which drives the moving vehicle 33 to reciprocate by rotating forward and backward. The radio frequency scanner reader 32 scans and identifies the RFID radio frequency tag on the blood sample and feeds back the scanned tag information to the control host 4. If it is the target blood sample, the control host 4 controls the drive motor 34 to stop moving, so that the moving vehicle 33 stops at the corresponding target blood sample position.

[0031] The control host 4 is electrically connected to the sample refrigerator 2, the radio frequency scanner reader 32 and the drive motor 34, and is used to control the movement and operation of the radio frequency scanning mechanism, as well as the refrigeration and preservation of the sample refrigerator 2.

[0032] For example, the control host 4 includes a controller module, a data storage module, a data input module, and a display module 41. The controller module uses a PLC to control the operation of the entire system; the data storage module stores the blood sample information scanned by the RF scanner 32, including the blood sample's entry and exit information; the data input module can input the target blood sample data as needed, including blood type, quantity, etc.; the data input module is configured as a touch unit integrated with the display module 41 or a keyboard separate from the display module 41. In this embodiment, the display module uses a touch screen display, and the data input module directly inputs data on the touch screen display. After the target blood sample information is input through the data input module, the controller module transmits the target blood sample data to the RF scanner 32. After the RF scanner 32 scans the target blood sample, it sends a sensing signal to the controller module. After receiving the sensing signal, the controller module sends a control command to the drive motor 34, which stops, causing the RF scanner 32 to stop at the placement position 21 corresponding to the target blood sample.

[0033] To facilitate the removal of the blood sample box 1, in this embodiment, each placement compartment 21 is provided with an ejection auxiliary mechanism 5 for pushing the blood sample box 1 out of the placement compartment 21. The ejection auxiliary mechanism 5 is turned on or off by moving or stopping the moving vehicle 33.

[0034] For example, the unloading auxiliary mechanism 5 includes a support base plate 51, an electromagnet 52, an elastic metal sheet 53, and a push rod 54. The support base plate 51 is located at the bottom of the placement compartment 21, serving as the bottom support for the placement compartment 21. The electromagnet 52 is installed on the rear side of the support base plate 51, i.e., the side away from the placement compartment 21, and is fixed to one end of the support base plate 51. One end of the elastic metal sheet 53 is fixedly connected to the bottom end of the support base plate 51 away from the electromagnet 52, and the other end of the elastic metal sheet 53 is a free end, extending below the electromagnet 52, with a 1cm gap between it and the electromagnet 52. A small magnet is fixed to the free end of the elastic metal sheet 53, and the electromagnet 52 is connected to the control main unit via a wire. The machine 4 is connected, and the power supply on the control host 4 is set to power the electromagnet 52; the push rod 54 is fixedly connected to the middle position of the side of the elastic metal sheet 53 facing the support base plate 51. The support base plate 51 has a through hole that extends into the placement compartment 21. The push rod 54 can pass through the support base plate 51 and extend into the placement compartment 21 to push out the blood sample box 1. When the electromagnet 52 is disconnected, the end of the push rod 54 is located in the through hole on the support base plate 51. When the electromagnet 52 is turned on, it attracts the free end of the elastic metal sheet 53, and the push rod 54 extends into the placement compartment 21 to push out the blood sample box 1.

[0035] In some embodiments, the positive and negative terminals of the electromagnet 52 extend to the outer wall of the sample refrigerator 2 and are respectively connected to a positive and negative contact connector 55. The mobile vehicle 33 is equipped with two positive and negative conductive rods 56 for contacting the positive and negative contact connectors 55, and the two conductive rods 56 are respectively connected to a power source via wiring. When the RF scanner 32 stops at the placement compartment 21 corresponding to the target blood sample, the positive and negative conductive rods 56 contact the two positive and negative contact connectors 55 respectively, activating the circuit of the electromagnet 52. The electromagnet 52 then activates and attracts the elastic metal sheet 53. The elastic metal sheet 53 uses a push rod 54 to push out the blood sample box 1 for easy retrieval by staff.

[0036] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
