[0002] For diabetic patients, their blood sugar index is very important and needs to be paid attention to and recorded regularly. In order to reduce the fluctuation of patients' blood sugar index, it needs to be controlled by drugs. Artificial insulin is a well-known drug for lowering blood sugar index. It must be administered parenterally to work in the human body. At present, the most common way to administer artificial insulin to diabetic patients is through subcutaneous injection, and it requires long-term regular injection.

[0003] The dose a diabetic patient needs to inject depends on his blood sugar index, which changes dynamically, and the correspondence between the blood sugar index and the injection dose is very strict. Summary of the invention

[0051] In view of the technical problems existing in the prior art, an embodiment of the present invention provides a method for intelligently monitoring injection dosage, the method comprising:

[0052] Obtaining the effective rotation angle of the injection plunger of the syringe;

[0053] Determining the axial movement distance of the injection push rod according to the effective rotation angle of the injection push rod;

[0054] According to the axial movement distance of the injection push rod, determining the injection dose corresponding to the axial movement distance of the injection push rod and saving the injection dose;

[0055] Alternatively, obtaining the axial movement distance of the injection push rod;

[0056] According to the axial movement distance of the injection push rod, an injection dose corresponding to the axial movement distance of the injection push rod is determined and saved.

[0057] Here, the execution subject of the method may be a device for intelligently monitoring the injection dosage, which may be installed on the syringe or may be outside the syringe but connected to and communicated with the syringe.

[0058] Here, there are two methods for intelligently monitoring the injection dose, which are implemented for different syringe structures. One syringe structure drives the injection plunger to move axially through spiral rotation during injection, and the other syringe structure directly pushes the injection plunger to move axially during injection. Therefore, the method, i.e., the steps, of intelligently monitoring the injection dose are different.

[0059] The angle here can be the circumferential angle of the injection rod relative to the outer shell of the syringe. For example, a detection reference point is specified on the outer shell of the syringe, and a detection tracking point is specified on the outer circle of the syringe push rod. The two coincide with each other in the initial position, that is, initially, the circumferential angle of the injection rod relative to the outer shell of the syringe is "0" degree.

[0060] It can be understood that obtaining the effective rotation angle of the injection plunger of the syringe includes:

[0061] Firstly, detecting the circumferential position of the injection push rod relative to the housing of the syringe to obtain an initial value of the circumferential angle;

[0062] Based on the initial value of the circumferential angle, the cumulative angle of rotation of the injection push rod along the first circumferential direction during an injection process is obtained; the cumulative angle is the effective rotation angle.

[0063] The structural design of the product is that only the rotation in the first circumferential direction will drive the injection push rod to move axially, otherwise the injection push rod remains stationary. In this way, no matter how the injection push rod moves during an injection process, the angle of rotation along the first circumferential direction is accumulated to obtain the rotation angle that has an effect on the axial movement, that is, the effective rotation angle.

[0064] Here, the first circumferential direction can be clockwise or counterclockwise, which is designed according to the specific product needs. However, once the product is designed and manufactured, it can only be one of the directions. Here, the first time is when the device for intelligently monitoring the injection dose is turned on, or the first time it is awakened after sleep. Generally, when no injection is made, the device for intelligently monitoring the injection dose will be turned off or enter sleep mode.

[0065] Based on the initial value of the circumferential angle, obtaining the cumulative angle of rotation of the injection push rod along the first circumferential direction during an injection process is a simpler and easier to implement way to obtain the effective rotation angle.

[0066] It can be understood that, based on the initial value of the circumferential angle, obtaining the cumulative angle of rotation of the injection push rod along the first circumferential direction during an injection process includes:

[0067] According to a preset time point, regularly detecting the circumferential position of the injection push rod relative to the syringe housing, and obtaining a plurality of circumferential angle update values;

[0068] Comparing a current circumferential angle update value with a circumferential angle update value detected at at least one previous time point, to determine an angle of rotation of the injection plunger in the first circumferential direction corresponding to the current circumferential angle update value;

[0069] The angles of rotation of a plurality of circumferential angle update values ​​in one injection process in the first circumferential direction are accumulated to obtain the accumulated angle of rotation of the injection push rod in the first circumferential direction in one injection process.

[0070] Here, the preset time points may be the same time intervals. In general, injection is performed at a uniform speed, so the detection time points are set to be evenly distributed.

[0071] By comparing with the updated value of the circumferential angle detected at the previous time point, the rotation direction can be determined relatively simply and quickly, that is, the rotation angle of the injection push rod in the first circumferential direction can be determined, which is a better implementation.

[0072] In addition, since the angle value will start from zero after one rotation, the two compared circumferential angle update values ​​need to be corrected according to the situation. The correction method is shown in the specific embodiment below.

[0073] It can be understood that comparing the current circumferential angle update value with the circumferential angle update value detected at at least one previous time point to determine the angle of rotation of the injection plunger in the first circumferential direction corresponding to the current circumferential angle update value includes:

[0074] Compare the current circumferential angle update value with the circumferential angle update values ​​detected at two previous time points, wherein the two previous circumferential angle update values ​​detected at the two previous time points are respectively the previous circumferential angle update value and the previous two circumferential angle update values;

[0075] The current circumferential angle update value is smaller than the previous circumferential angle update value, and the previous circumferential angle update value is smaller than the previous two circumferential angle update values, then the difference between the current circumferential angle update value and the previous two circumferential angle update values ​​is the angle at which the injection push rod rotates in the first circumferential direction;

[0076] The current circumferential angle update value is less than the previous circumferential angle update value, and the previous circumferential angle update value is greater than the previous two circumferential angle update values, then the difference between the current circumferential angle update value and the previous circumferential angle update value is the angle at which the injection push rod rotates in the first circumferential direction;

[0077] The current circumferential angle update value is greater than the previous circumferential angle update value, and the previous circumferential angle update value is less than the previous two circumferential angle update values, then the difference between the previous circumferential angle update value and the previous two circumferential angle update values ​​is the angle of rotation of the injection push rod in the first circumferential direction.

[0078] That is, the rotation angle of the injection push rod in the first circumferential direction is determined by comparing the updated values ​​of the circumferential angle detected at three time points. In this way, the influence of the following two situations on the detection accuracy can be avoided:

[0079] 1) First rotate along the first circumferential direction, and then rotate along the second circumferential direction;

[0080] 2) first rotate along the second circumferential direction, and then rotate along the first circumferential direction;

[0081] In both cases, a part of the particles rotate along the second circumferential direction, and therefore need to be removed. In this way, the detection result is more accurate, which is a better implementation method.

[0082] It can be understood that the comparison of the current circumferential angle update value with the circumferential angle update values ​​detected at two previous time points includes:

[0083] According to the values ​​of the current circumferential angle update value and the circumferential angle update values ​​detected at two previous time points, the current circumferential angle update value and the circumferential angle update values ​​detected at two previous time points are corrected.

[0084] In this way, it is possible to avoid the situation where the circumferential angle update value at a later time point is smaller than the previous circumferential angle update value after one rotation, thereby obtaining an erroneous result, which is a better implementation method.

[0085] The embodiment of the present invention further provides a device for intelligently monitoring injection dosage, the device comprising a first acquisition module, a first determination module and a second determination module; wherein,

[0086] The first acquisition module is used to acquire the effective rotation angle of the injection plunger of the syringe;

[0087] The first determining module is used to determine the axial movement distance of the injection push rod according to the effective rotation angle of the injection push rod;

[0088] The second determination module is used to determine the injection dose corresponding to the axial movement distance of the injection push rod according to the axial movement distance of the injection push rod, and save it;

[0089] Alternatively, the device includes a second acquisition module and a third determination module; wherein,

[0090] The second acquisition module is used to acquire the axial movement distance of the injection push rod;

[0091] The third determination module is used to determine the injection dose corresponding to the axial movement distance of the injection push rod according to the axial movement distance of the injection push rod, and save it.

[0092] The embodiment of the present invention further provides an intelligent injector, the intelligent injector comprising:

[0093] Injection plunger;

[0094] An angle sensor for detecting the rotation of the injection plunger;

[0095] A processing component for obtaining the injection dose of the smart syringe according to the measurement value of the angle sensor.

[0096] The embodiment of the present invention also provides an injection system for intelligently monitoring injection dosage, the injection system comprising an intelligent terminal and the intelligent injector described above; the intelligent terminal and the intelligent injector are connected via wired or wireless communication. In this way, the dosage injected by the intelligent injector can be transmitted to the intelligent terminal for easy recording and statistics.

[0097] An embodiment of the present invention further provides a computer, comprising: a memory, a communication bus, and a processor, wherein:

[0098] The memory is used to store a method program for intelligently monitoring injection dosage;

[0099] The communication bus is used to realize the connection and communication between the memory and the processor;

[0100] The processor is used to execute the method program for intelligently monitoring injection dosage stored in the memory to implement the steps of any one of the methods for intelligently monitoring injection dosage as described above.

[0101] An embodiment of the present invention further provides a computer-readable storage medium, on which an executable program is stored. When the executable program is executed by a processor, the steps of the method for intelligently monitoring injection dosage as described above are implemented.

[0102] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0103] Embodiment 1

[0104] This embodiment provides a method for intelligently monitoring injection dosage. The method of this embodiment is for a syringe whose injection push rod is a spirally rotating structure. It can be understood that another structure can also be executed with reference, but the steps are different, see above.

[0105] The method of this embodiment can be performed by a device for intelligently monitoring the injection dosage, which can be installed on the syringe or outside the syringe but connected and communicated with the syringe; Figure 1 As shown, the method includes:

[0106] Step 101: obtaining an effective rotation angle of an injection plunger of a syringe;

[0107] Specifically, obtaining the effective rotation angle of the injection plunger of the syringe includes:

[0108] Firstly, detecting the circumferential position of the injection push rod relative to the housing of the syringe to obtain an initial value of the circumferential angle;

[0109] Based on the initial value of the circumferential angle, the cumulative angle of rotation of the injection push rod along the first circumferential direction during an injection process is obtained; the cumulative angle is the effective rotation angle.

[0110] More specifically, obtaining the cumulative angle of rotation of the injection push rod along the first circumferential direction during an injection process based on the initial value of the circumferential angle includes:

[0111] According to a preset time point, regularly detecting the circumferential position of the injection push rod relative to the syringe housing, and obtaining a plurality of circumferential angle update values;

[0112] Comparing a current circumferential angle update value with a circumferential angle update value detected at at least one previous time point, to determine an angle of rotation of the injection plunger in the first circumferential direction corresponding to the current circumferential angle update value;

[0113] The angles of rotation of a plurality of circumferential angle update values ​​in one injection process in the first circumferential direction are accumulated to obtain the accumulated angle of rotation of the injection push rod in the first circumferential direction in one injection process.

[0114] In this embodiment, the first circumferential direction is defined as: the injection plunger rotates clockwise when viewed from above the syringe.

[0115] In this embodiment, the preset time point is detected every 100 milliseconds.

[0116] In this embodiment, in order to prevent the circumferential angle update value at a later time point from being smaller than the previous circumferential angle update value after a rotation, the two compared circumferential angle update values ​​need to be corrected. The correction rules are as follows:

[0117] If Angle_1>315 degrees and Angle_2<45 degrees, then: Angle_2=Angle_2+360

[0118] If Angle_2>315 degrees and Angle_1<45 degrees, then: Angle_1=Angle_1+360

[0119] Among them, Angle_2 is the current circumferential angle update value, and Angle_1 is the previous circumferential angle update value.

[0120] More specifically, comparing the current circumferential angle update value with the circumferential angle update value detected at at least one previous time point to determine the angle of rotation of the injection plunger in the first circumferential direction corresponding to the current circumferential angle update value includes:

[0121] Compare the current circumferential angle update value with the circumferential angle update values ​​detected at two previous time points, wherein the two previous circumferential angle update values ​​detected at the two previous time points are respectively the previous circumferential angle update value and the previous two circumferential angle update values;

[0122] The current circumferential angle update value is smaller than the previous circumferential angle update value, and the previous circumferential angle update value is smaller than the previous two circumferential angle update values, then the difference between the current circumferential angle update value and the previous two circumferential angle update values ​​is the angle at which the injection push rod rotates in the first circumferential direction;

[0123] The current circumferential angle update value is less than the previous circumferential angle update value, and the previous circumferential angle update value is greater than the previous two circumferential angle update values, then the difference between the current circumferential angle update value and the previous circumferential angle update value is the angle at which the injection push rod rotates in the first circumferential direction;

[0124] The current circumferential angle update value is greater than the previous circumferential angle update value, and the previous circumferential angle update value is less than the previous two circumferential angle update values, then the difference between the previous circumferential angle update value and the previous two circumferential angle update values ​​is the angle of rotation of the injection push rod in the first circumferential direction.

[0125] That is, the rotation angle of the injection push rod in the first circumferential direction is determined by comparing the updated values ​​of the circumferential angles detected at three time points. There are several specific situations:

[0126] (1) If the current circumferential angle update value is less than the previous circumferential angle update value, and the previous circumferential angle update value is less than the previous two circumferential angle update values, it can be determined that the circumferential angle update values ​​detected at the three time points are all rotated along the first circumferential direction, and therefore the difference between the current circumferential angle update value and the previous two circumferential angle update values ​​is the angle of rotation of the injection push rod in the first circumferential direction;

[0127] (2) If the current circumferential angle update value is less than the previous circumferential angle update value, and the previous circumferential angle update value is greater than the previous two circumferential angle update values, it can be determined that the rotation is counterclockwise from the first time point to the second time point, and the rotation is clockwise from the second time point to the third time point. Therefore, the difference between the current circumferential angle update value and the previous circumferential angle update value is the angle of rotation of the injection push rod in the first circumferential direction, that is, the counterclockwise rotation angle between the first time point and the second time point is eliminated;

[0128] (3) If the current circumferential angle update value is greater than the previous circumferential angle update value, and the previous circumferential angle update value is less than the previous two circumferential angle update values, it can be determined that the rotation is clockwise from the first time point to the second time point, and the rotation is counterclockwise from the second time point to the third time point. Therefore, the difference between the previous circumferential angle update value and the previous two circumferential angle update values ​​is the angle of rotation of the injection rod in the first circumferential direction, that is, the counterclockwise rotation angle from the second time point to the third time point is eliminated.

[0129] (4) If the current circumferential angle update value is greater than the previous circumferential angle update value, and the previous circumferential angle update value is greater than the previous two circumferential angle update values, it can be determined that the circumferential angle update values ​​detected at the three time points are all rotating along the second circumferential direction, that is, they are all rotating counterclockwise, and need to be discarded and not accumulated into the angle of rotation of the injection push rod along the first circumferential direction during an injection process.

[0130] Step 102: determining the axial movement distance of the injection push rod according to the effective rotation angle of the injection push rod;

[0131] Because it is a spiral motion, the axial movement distance can be calculated based on the rotation angle (ie, the number of rotations) and the corresponding spiral parameters (such as pitch).

[0132] Step 103: According to the axial movement distance of the injection push rod, determine the injection dose corresponding to the axial movement distance of the injection push rod, and save it.

[0133] The axial movement distance of the injection push rod can push the movement of the piston in the medicine bottle in the syringe, thereby determining the corresponding injection dose.

[0134] Embodiment 2

[0135] This embodiment provides a device for intelligently monitoring injection dosage, such as Figure 2 As shown, the device 200 includes a first acquisition module 21, a first determination module 22 and a second determination module 23; wherein,

[0136] The first acquisition module 21 is used to acquire the effective rotation angle of the injection plunger of the syringe;

[0137] The first determination module 22 is used to determine the axial movement distance of the injection push rod according to the effective rotation angle of the injection push rod;

[0138] The second determination module 23 is used to determine the injection dose corresponding to the axial movement distance of the injection push rod according to the axial movement distance of the injection push rod, and save it.

[0139] Specifically, the first acquisition module 21 is used to:

[0140] Firstly, detecting the circumferential position of the injection push rod relative to the housing of the syringe to obtain an initial value of the circumferential angle;

[0141] Based on the initial value of the circumferential angle, the cumulative angle of rotation of the injection push rod along the first circumferential direction during an injection process is obtained; the cumulative angle is the effective rotation angle.

[0142] More specifically, the first acquisition module 21 is further used for:

[0143] According to a preset time point, regularly detecting the circumferential position of the injection push rod relative to the syringe housing, and obtaining a plurality of circumferential angle update values;

[0144] Comparing a current circumferential angle update value with a circumferential angle update value detected at at least one previous time point, to determine an angle of rotation of the injection plunger in the first circumferential direction corresponding to the current circumferential angle update value;

[0145] The angles of rotation of a plurality of circumferential angle update values ​​in one injection process in the first circumferential direction are accumulated to obtain the accumulated angle of rotation of the injection push rod in the first circumferential direction in one injection process.

[0146] More specifically, the first acquisition module 21 is further used for:

[0147] Compare the current circumferential angle update value with the circumferential angle update values ​​detected at two previous time points, wherein the two previous circumferential angle update values ​​detected at the two previous time points are respectively the previous circumferential angle update value and the previous two circumferential angle update values;

[0148] The current circumferential angle update value is smaller than the previous circumferential angle update value, and the previous circumferential angle update value is smaller than the previous two circumferential angle update values, then the difference between the current circumferential angle update value and the previous two circumferential angle update values ​​is the angle at which the injection push rod rotates in the first circumferential direction;

[0149] The current circumferential angle update value is less than the previous circumferential angle update value, and the previous circumferential angle update value is greater than the previous two circumferential angle update values, then the difference between the current circumferential angle update value and the previous circumferential angle update value is the angle at which the injection push rod rotates in the first circumferential direction;

[0150] The current circumferential angle update value is greater than the previous circumferential angle update value, and the previous circumferential angle update value is less than the previous two circumferential angle update values, then the difference between the previous circumferential angle update value and the previous two circumferential angle update values ​​is the angle of rotation of the injection push rod in the first circumferential direction.

[0161] Specifically, the smart injector 300 also includes other components for completing the injection, such as a housing for accommodating the injection push rod 31, a bracket for mounting a medicine bottle, etc., which are not the content of the invention of the embodiment of the present invention and are not described in detail.

[0162] Embodiment 4

[0163] This embodiment provides an injection system for intelligently monitoring injection dosage, such as Figure 4 As shown, the system includes a smart terminal 41 and the smart injector 42 described in the third embodiment; the smart terminal 41 and the smart injector 42 are connected via wired or wireless communication.

[0164] In this embodiment, the smart terminal 41 is a mobile phone. A dedicated application program is installed on the mobile phone, namely, an application (APP) for monitoring the injection dosage.

[0165] The APP is used to receive data collected by the smart injector 42, manage the current user's personal identity information and previous injection dosage information, count the injection dosage and trend within the user's specified time, open this information to trusted medical staff and expert systems, and receive suggestions and reminder messages from medical staff.

[0166] The smart terminal 41 and the smart injector 42 are wirelessly connected via Bluetooth Low Energy (BLE), and the information transmitted between the two is encrypted. The transmitted information includes the dose and time of the current or recent injections, the identity document (ID) information of the smart injector 42, and the remaining battery power of the smart injector 42.

[0167] Specifically, the smart terminal 41 and the smart injector 42 need to be paired and bound through a low-power Bluetooth wireless connection. During the pairing process, you need to enter a pairing password. After pairing, the smart terminal 41 and the smart injector 42 are bound together, and they can be automatically connected next time without pairing. One smart terminal 41 can be bound to multiple smart injectors 42, and one smart injector 42 can generally only be bound to one smart terminal 41. If you need to change the smart terminal 41, you can unbind it from the previous one.

[0168] In order to more clearly understand the pairing and data transmission between the smart terminal 41 and the smart injector 42, further description is given below in conjunction with the accompanying drawings.

[0169] like Figure 5 As shown, the pairing process of the smart terminal 41 and the smart injector 42 includes the following process:

[0170] 501: the intelligent injector 42 is turned on and initialized;

[0171] 502: The Bluetooth component of the smart injector 42 broadcasts, and the broadcast content includes the device type, transmission power (TxPower), etc.; the smart terminal 41 calls the application programming interface (API) of the terminal operating system to scan the BLE, and filters the scanned information according to the device type, and calculates the signal strength indication (RSSI) received by the current scanned broadcast packet, which can also be considered as the path loss (RSSI-Tx Power);

[0172] 503: the intelligent terminal 41 initiates a Bluetooth attribute (GATT, Generic Attribute Profile) connection; that is, the device with the smallest path loss is selected to initiate a Bluetooth GATT attribute connection. The intelligent injector is the closest and is the device with the smallest path loss.

[0173] 504: the smart injector 42 requests to pair with the smart terminal 41;

[0174] 505: User enters pairing password;

[0175] 506: the intelligent terminal 41 sends the pairing password to the pairing request;

[0176] 507: The pairing password is correct, the pairing is successful, the two are bound and can transmit data to each other.

[0177] Here, the pairing password is encrypted using a 256-bit elliptic encryption algorithm. After binding, the pairing information is stored in their respective memories, and they can be automatically connected in the future without having to enter the pairing password.

[0178] like Figure 6 As shown, the data transmission between the smart terminal 41 and the smart injector 42 includes the following process:

[0179] 601: Bluetooth connection; the smart injector 42 automatically connects to the smart terminal 41 after being turned on. If it has not been bound before, it needs to be bound first and then connected;

[0180] 602: the intelligent terminal 41 sends current timestamp information;

[0181] 603: the smart injector 42 sends its own ID and current power level;

[0182] 604: the intelligent terminal 41 displays the device information of the current intelligent injector 42;

[0183] 605: Synchronize historical injection dosage information;

[0184] 606: the smart injector 42 clears the historical injection dosage information to ensure that the memory of the smart injector has sufficient storage space;

[0185] 607: The user presses the syringe to inject;

[0186] 608: the intelligent injector 42 monitors the injection dosage of this injection process;

[0187] 609: The intelligent injector 42 sends the injection dose of this injection process and the current timestamp.
