[0030] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below with reference to the accompanying drawings.

[0031] like Figure 1-2 As shown, an embodiment of the present invention discloses a digital metering IOT system for a needle-free syringe, comprising a needle-free syringe and a digital metering IOT system disposed on the needle-free syringe;

[0032] The digital metering IOT system includes a control unit MCU and a power supply module, a wireless communication module, a memory and an injection detection module connected to the control unit MCU;

[0033] The power supply module supplies power to all modules in the digital metering IOT system; the control unit MCU is connected to the cloud server through the wireless communication module, and the cloud server is connected to the user terminal;

[0034] The injection detection module includes a plurality of TMR sensors and a plurality of magnets, wherein the plurality of magnets are arranged around the rotating rotor module of the needle-free syringe, and the TMR sensors are arranged on the housing of the needle-free syringe and corresponding to the magnets;

[0035] During drug injection by the needle-free injector, the rotating rotor module drives multiple magnets to rotate, and the control unit MCU senses the positions of different magnets through the TMR sensor to determine the rotation angle, and determines the drug injection amount according to the rotation angle.

[0036] like Figure 2As shown, the rotating rotor module is evenly divided into 8 positions along the circumferential direction, wherein the two corresponding positions above and below are empty positions (such as positions 1 and 5 in the figure), and there are 6 magnets, which are respectively arranged at the 6 positions excluding the empty positions (such as positions 2, 3, 4, 6, 7 and 8 in the figure);

[0037] There are three TMR sensors, which are respectively connected to the control unit MCU. The three TMR sensors are arranged at equal intervals and correspond to three adjacent position points.

[0038] like Figure 1 As shown, the system also includes a UI control unit, which includes a multi-function button, a display, and a buzzer. The multi-function button, display, and buzzer are respectively connected to the control unit MCU and are respectively arranged on the housing of the needle-free syringe.

[0039] The multi-function button is used to receive the user's input command information and send it to the module that needs to be executed corresponding to the input command information through the control unit MCU. The control unit MCU is connected to the cloud server through the wireless communication module and transmitted to the user terminal through the cloud server;

[0040] The display is used to display the user's input instruction information, the module data after executing the input instruction information, the dosage and dosage, the medication time and the number of medications, etc. The control unit MCU is connected to the cloud server through the wireless communication module and transmits the information to the user terminal through the cloud server;

[0041] When a module failure occurs during operation, the buzzer is controlled by the control unit MCU to sound an alarm to the user, and the abnormal data information is displayed on the display through the control unit MCU. The control unit MCU is connected to the cloud server through a wireless communication module and transmitted to the user terminal through the cloud server.

[0042] Specifically, the system further includes an NTC temperature acquisition unit;

[0043] The NTC temperature acquisition unit is connected to the control unit MCU interface, and is used to detect real-time temperature change information inside the needle-free syringe, and display the real-time temperature change information on the display through the control unit MCU. The control unit MCU is connected to the cloud server through a wireless communication module and transmits the information to the user terminal through the cloud server;

[0044] In order to achieve the above technical solution, the preset temperature range is input into the control unit MCU through the multi-function button; when the NTC temperature acquisition unit detects that the temperature change information inside the needle-free syringe is not within the preset temperature range, the control unit MCU controls the buzzer to sound an alarm and displays it on the display. The control unit MCU communicates with the cloud server through the wireless communication module and transmits the information to the user terminal through the cloud server.

[0045] Specifically, the wireless communication module is a Bluetooth communication module or a Wi-Fi communication module.

[0046] Specifically, the power supply module includes an electrically connected rechargeable battery and an LDO, the rechargeable battery supplies power to the LDO, and the LDO supplies power to the digital metering IOT system.

[0047] To further optimize the above technical effects, the TMR sensing device installed in the syringe can further detect the user's medication information by detecting the changes in the rotating rotor module. Since there is no direct electrical connection between the digital metering IOT system and the needle-free syringe, the six magnets embedded in the needle-free syringe and the three TMR sensors together form a rotation angle detection system to identify the user's medication amount.

[0048] In order to achieve the above technical solution, the digital metering IOT system for needle-free syringes in this application is suitable for needle-free syringes that perform injections internally by rotating a screw, such as: Bluestar needle-free injection pusher Luqing Medical Equipment No. 20180100 Model ZHTE003.

[0049] The screw is driven by the rotating rotor module to perform drug addition and injection.

[0050] According to the inner diameter of the needle-free syringe, the pitch of the screw thread and the rotation angle, the dosage can be accurately measured. The dosage calculation formula is: Q=α*p*D 2 / 8, where α is the radian of rotation, p is the pitch, and D is the inner diameter of the syringe.

[0051] Arrangement see Figure 2 As shown, according to the TMR detection accuracy, when the diameter of the needle-free syringe is greater than or equal to 2 cm, it can detect a rotation angle of at least 45 degrees and can distinguish between forward and reverse rotation. The specific detection principle is as follows: the starting position of the product is as follows: Figure 2As shown, sensor B is in position 1. At this time, the outputs of sensors A, B, and C are 0, 1, and 0 respectively; when the product starts to rotate clockwise and apply pressure, sensor B turns to position 2. At this time, the outputs of sensors A, B, and C are 1, 0, and 0 respectively. At this time, it can be calculated that the product has rotated 45 degrees clockwise. If the product rotates counterclockwise, sensor B turns to position 8. At this time, the outputs of sensors A, B, and C are 0, 0, and 1 respectively. At this time, it can be calculated that the product has rotated 45 degrees counterclockwise, so this design can identify the forward and reverse rotation of the product; when sensor B continues to rotate clockwise at position 2 and turns to position 3, the outputs of sensors A, B, and C are 0, 0, and 0 respectively. At this time, it can be calculated that the product has been relatively rotated. The product has rotated 90 degrees clockwise relative to its starting position; when sensor B continues to rotate clockwise at position 3 and moves to position 4, the outputs of sensors A, B, and C are 0, 0, and 1 respectively. It can be calculated that the product has rotated 135 degrees clockwise relative to its starting position; when sensor B continues to rotate clockwise at position 4 and moves to position 5, the outputs of sensors A, B, and C are 0, 1, and 0 respectively. It can be calculated that the product has rotated 180 degrees clockwise relative to its starting position; when sensor B continues to rotate clockwise at position 5 and moves to position 6, the outputs of sensors A, B, and C are 1, 0, and 0 respectively. It can be calculated that the product has rotated 225 degrees clockwise relative to its starting position; Sensor B continues to rotate clockwise at position 6, and when it reaches position 7, the outputs of sensors A, B, and C are 0, 0, and 0 respectively. At this time, it can be calculated that the product has rotated 270 degrees clockwise relative to the starting position; when sensor B continues to rotate clockwise at position 7, and when it reaches position 8, the outputs of sensors A, B, and C are 0, 0, and 1 respectively. At this time, it can be calculated that the product has rotated 315 degrees clockwise relative to the starting position; when sensor B continues to rotate clockwise at position 8, and when it reaches position 1, the outputs of sensors A, B, and C are 0, 1, and 0 respectively. At this time, it can be calculated that the product has rotated 360 degrees clockwise relative to the starting position. After the clockwise pressurization is completed, counterclockwise rotation needs to be increased. When the medicine is applied, and so on, you can know how many degrees the final cumulative rotation is, so as to calculate the dosage; the sensor output corresponding to each position is shown in (Table 1), and the user can set and adjust the parameter settings through the multi-function button. The temperature information collected by the NTC temperature acquisition unit and the injection information detected by the injection detection module are transmitted to the mobile phone, cloud and other terminals through the wireless communication module for storage, statistics and analysis of the injection amount data. It can effectively record the user's medication dosage, medication time and number of medications and other information. When an abnormality occurs during the operation of the module and the NTC temperature acquisition unit detects a temperature abnormality, an alarm will be sounded through the control unit MCU through the buzzer, and the information will be displayed on the monitor and transmitted to the user terminal.
