[0033] Equipment shell, control unit and identification unit, the equipment shell provides the attachment site of control unit and identification unit, the signal output end and signal input end of control unit are connected with the signal input end and signal output end of identification unit respectively;

[0034] The recognition unit includes a consumable recognition camera 1, a touch screen 3, an RFID controller, a face recognition camera 2, a finger vein collector 5 and an IC card reader 4, the consumable recognition camera 1 is installed to the top end of the equipment shell, the touch screen 3 is inlaid to the front panel of the equipment shell by integrated molding, the RFID controller, the finger vein collector 5 and the IC card reader 4 are all installed to the upper panel of the equipment shell, the control unit includes an embedded computer 7 and multiple communication interfaces, the embedded computer 7 is connected to the consumable recognition camera 1, the touch screen 3, the RFID controller, the face recognition camera 2, the finger vein collector 5 and the IC card reader 4 respectively through the communication interfaces.

[0035] Specifically,

[0036] The embedded computer 7 is installed to the inside of the equipment shell through a fixed support, a heat management channel 9 is designed between the computer and the shell, a temperature sensor is installed in the inside of the equipment shell and connected with the heat dissipation system of the computer. When the temperature sensor detects that the temperature in the shell rises, the computer automatically adjusts the rotating speed of the heat dissipation fan and discharges the hot air outside the shell through the heat management channel 9, then the touch screen 3 is installed by the design of integrated molding with the front panel of the shell, a pressure sensing type connection mechanism is established between the touch screen 3 and the shell, in addition to the data line transmission touch signal, a layer of pressure sensing film is installed between the back of the touch screen 3 and the front panel of the shell, when the operator touches the screen of the touch screen 3, the pressure sensing film can detect the pressure value of the touch point in real time and transmit it to the computer, the computer can more accurately judge the operation intention of the user according to the size and change of the pressure value.

[0037] The consumable recognition camera 1 is connected with the self-adaptive rotating support through the quick plug-in interface. The self-adaptive rotating support is made of light and high-strength aluminum alloy material, has good rigidity and corrosion resistance, and has a disc-shaped appearance design. A cylindrical rotating shaft 12 is arranged at the center position. A plurality of neodymium iron boron strong magnets 13 are embedded in the area where the device shell top and the self-adaptive rotating support are in contact. The neodymium iron boron strong magnets 13 are arranged in a ring shape. The magnetic attraction layer at the bottom of the support is made of a thin iron sheet covered with a layer of rubber magnetic material. The iron sheet ensures the magnetic attraction strength, and the rubber magnetic material plays a buffering role to prevent the support from causing damage to the device shell during the adsorption process due to collision. At the same time, it also increases the friction force, so that the support can be stably fixed after being rotated to the required angle and will not easily displace due to external interference. The quick plug-in interface socket at the top end of the self-adaptive rotating support adopts a standard HDMI female socket style.

The insulating rubber material provides good electrical insulation performance to prevent short circuits between the wires. The spiral metal shielding layer effectively blocks external electromagnetic interference to ensure that data transmission is not affected. One end of the cable is connected to the data line interface of the camera through a specially designed rotating joint. The rotating joint inside adopts a high-precision ball bearing structure, allowing the cable to rotate freely within a certain range to adapt to the multi-angle adjustment requirements of the camera. The other end is connected to the corresponding branch wire slot in the internal wire slot, guided by the wire slot, and finally connected to the interface on the mainboard to realize stable data transmission. The rear end of the device shell 6 is provided with a power interface 11. The power interface 11 is connected to an external power supply to power the entire device.

[0038] The bioelectric signal output by the finger vein collector 5 is connected to the input end of the signal amplification unit through the shielded wire in the flexible conduit. The signal amplification unit uses an operational amplifier. On the circuit board, the signal input end uses a high-precision, low-temperature-drift resistor for impedance matching, ensuring complete signal transmission into the operational amplifier. The output end of the operational amplifier is directly connected to the input end of the filter unit. The two are connected through short and thick printed circuit board wires. The filter unit is composed of a second-order Butterworth active filter. Its input end receives the amplified signal from the signal amplification unit. The signal is filtered through the filter's internal precision capacitor and inductor network for frequency screening. The filtered signal is output from the output end. The output signal of the filter unit is connected to the input port of the noise reduction unit. After filtering, most of the noise has been filtered out, but some residual noise may still exist. The relatively pure bioelectric signal output by the filter unit is sent to the noise reduction unit for more in-depth noise suppression processing. The noise reduction unit is realized using a digital signal processor (DSP) chip and internal filtering algorithms. The input end of the noise reduction unit is connected to the output end of the filter unit through printed circuit board wires to receive the filtered signal. The DSP chip samples the input signal and, after internal algorithm processing, outputs the noise-reduced signal to the signal conditioning unit through a high-speed parallel bus. Finally, the signal conditioning unit is mainly composed of a high-precision digital-to-analog converter (DAC) and an analog multiplier, etc. The DAC is used to convert the digital signal output by the digital signal processor back to an analog form. The analog multiplier normalizes the converted analog signal in amplitude, making its amplitude meet the standard range requirements of the analog input port of the embedded computer 7.

[0039] The RFID control board 8 is installed into the hot-pluggable expansion slot inside the device shell, and on both sides of the expansion slot, elastic fixing buckles are provided. When the RFID control board is inserted into place, the buckles automatically lock the board card to prevent loosening. At the same time, a guide groove is provided at the bottom to assist the accurate insertion of the control board, avoiding damage to the board card or the expansion slot due to misinsertion. Finally, the face recognition camera 2 is placed in the reserved space inside the device shell above the touch screen 3. A pop-up mechanism is provided at the connection between the device shell and the face recognition camera 2. The core component of the pop-up mechanism, the drive motor, is closely matched with the transmission gear set to realize accurate power transmission. The drive motor is a small, high-torque DC brushless motor, which has precise speed control capability and fast response characteristics. The signal control end of the motor is connected to the special control interface of the embedded computer 7 through fine and well-shielded wires. The transmission gear set is composed of a driving gear and a driven gear that mesh with each other. The driving gear is rigidly connected to the output shaft of the drive motor, and the two are connected by a high-precision key connection method to ensure the concentricity and stability of power transmission. The driven gear is connected to one end of the transmission rod through a pin. The transmission rod is arranged along the guide rail direction. The guide rail is fixedly installed inside the device shell and made of high-strength aluminum alloy. The transmission rod is connected to the face recognition camera 2 through a sliding block. The sliding block is nested on the guide rail and uses a ball guide between the guide rail. When the device runs to the step where face recognition is needed, the embedded computer 7 sends a start instruction to the signal control end of the drive motor according to the preset program logic and the trigger conditions of the current operation process. After receiving the instruction, the drive motor starts quickly and rotates at the pre-set speed, driving the driving gear connected to it to rotate synchronously.

[0040] Due to the close meshing of the driving gear and the driven gear, the rotational motion of the driving gear is transmitted to the driven gear. The driven gear converts the rotational power into linear motion, driving the transmission rod connected to it to extend outward along the guide rail direction. The transmission rod is rigidly connected to the face recognition camera 2 through the sliding block, pushing the camera to smoothly pop out from the storage position inside the device shell.

[0041] The specific operation steps are as follows:

[0042] Labeling mode: can identify consumable original factory code UDI information to print paper labels or RFID labels, or can identify consumable self-assigned code labels to print RFID labels.

[0043] 1. The operator places a single consumable in the labeling and coding device recognition area.

[0044] 2. The device recognizes the consumable self-assigned code or UDI code on the consumable, analyzes the corresponding code information, and matches the consumable information in the database, and binds with the RFID tag EPC information.

[0045] 3. The operator pastes the printed label on the consumable packaging.

[0046] 4. Repeat operation 1 until completion.

[0047] 5. In the above process, the system simultaneously stores the image data collected by the high-definition camera and the face recognition camera 2 during the consumable identification process and the label information printed at the printing station.

[0048] Correlation mode: only used to identify the original factory code (UDI code) or the self-assigned code of the consumable, and write information to the RFID tag chip. The RFID tag itself does not print information.

[0049] 1. The operator performs the RFID blank label pasting work on the consumables to be assigned codes in batches.

[0050] 2. Place a single consumable in the identification area of the label assignment device.

[0051] 3. The device identifies the self-assigned code or UDI code on the consumable, analyzes the corresponding code information, matches the consumable information in the database, and writes the corresponding barcode information to the RFID chip.

[0052] 4. Repeat operation 2 until completion.

[0053] 5. In the above process, the system simultaneously stores the image data collected by the high-definition camera and the face recognition camera 2 during the consumable identification process and the label information printed at the printing station.

[0054] 6. If the label needs to be recycled, place the label in the identification area of the label assignment device, and the operating system will perform label unbinding.

[0055] Embodiment 2

[0056] In some scenarios with high requirements for operation safety, such as the management of high-value medical consumables or the entry of sensitive information, the operator needs to be authenticated. At this time, the operator can choose to authenticate through the face recognition camera 2, the finger vein collector 5, or the IC card reader 4. If face recognition is selected, the embedded computer 7 will drive the face recognition camera 2 to start. The face recognition camera 2 is installed inside the device shell above the touch screen 3, and is connected to the shell through a pop-up mechanism. When face recognition is needed, the embedded computer 7 sends a control signal to the drive motor of the pop-up mechanism, the output shaft of the drive motor drives the transmission gear set to operate, the driven gear in the transmission gear set drives the transmission rod, and the transmission rod pushes the face recognition camera 2 out of the shell through the slider on the guide rail. The face recognition camera 2 collects the facial image of the operator, transmits the image data to the embedded computer 7, and the computer runs the face recognition algorithm to compare with the pre-stored face database to verify the operator's identity.

[0057] If the finger vein collection is selected, the operator places the finger in the ergonomic recess on the upper panel of the device shell, and the finger vein collector 5 is fixed to the bottom of the recess by the elastic fixing clamp, tightly adhering to the finger to collect the bioelectric signals of the finger vein. The collected bioelectric signals are transmitted to the embedded computer 7 through the flexible conduit and internal wire slot, passing through the bioelectric signal optimization circuit along the way. The signal amplification unit in the bioelectric signal optimization circuit first amplifies the weak bioelectric signals to an appropriate amplitude, the filtering unit removes the noise components in the signal, the noise reduction unit further reduces the residual noise, and the signal conditioning unit performs amplitude normalization, phase correction and other processing on the signal. Finally, the optimized signal is transmitted to the embedded computer 7, which runs the finger vein recognition algorithm and compares it with the finger vein information in the database to complete the identity verification.

[0058] If the IC card reader 4 is selected, the operator inserts the IC card into the IC card reader 4 installed inside the anti-magnetic interference cabin, and the IC card reader 4 is connected to the embedded computer 7 through the metal shielded data line, reads the information in the card and transmits it to the computer, and the computer verifies whether the identity information in the card matches the preset permission to complete the identity verification. Only after the identity verification is passed, the operator can continue the subsequent label coding operation to ensure the safety and compliance of the operation. After the consumable identification and personnel identity verification (if any) are completed, the embedded computer 7 generates the corresponding RFID tag content according to the identified consumable information. The RFID control board of the RFID controller receives instructions from the embedded computer 7, drives the RFID antenna to emit radio frequency signals, activates the pre-pasted RFID tag on the medical consumable, and realizes efficient radio frequency signal transmission between the RFID antenna and the tag through the radio frequency cable to ensure the stability and strength of the signal.

[0059] The RFID control board 8 interacts with the tag to write the generated tag content into the tag and read the existing information in the tag to check and ensure the accuracy of the written information. After writing is completed, the RFID control board 8 reads the tag information again and feeds back the reading result to the embedded computer 7, and the computer displays the read-write result on the touch screen 3 for the operator to confirm, completing the entire RFID tag read-write process. Finally, the embedded computer 7 generates a tag content containing detailed information of the consumable according to the consumable identification result and the preset tag template, including text, bar code, two-dimensional code and other forms. The format, layout and other parameters of the tag content can be flexibly adjusted on the touch screen 3 according to the management requirements and standards of the hospital. The computer transmits the generated tag content to the label printer connected to the device through the external socket 10, and the label printer prints the label according to the requirements after receiving the instructions.

[0060] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
