Technical Field
[0001] The present application relates to the technical field of medical devices, and in particular to a patch-type insulin pump and an insulin injection system. Background Art
[0002] At present, patch-type insulin pumps are able to automatically inject and push medicine. In order to ensure that the amount of medicine injected by the patch-type insulin pump is accurate, before injecting the medicine, the user needs to inject the insulin liquid in the standard medicine bottle into the medicine storage tank of the patch-type insulin pump in advance according to the instructions, and then the patch-type insulin pump will inject the medicine. However, due to errors in human operation, the user may not inject the medicine according to the instructions when injecting the medicine into the medicine storage tank, resulting in insufficient amount of medicine injected into the medicine storage tank (a / the drug leaks at the needle and is not completely injected into the medicine storage tank; b / the syringe scale is worn or missing, and the amount of medicine inhaled is insufficient; c / the medicine storage tank is accidentally damaged and the medicine flows out;) or too much (the standard amount is injected according to the doctor's recommended dosage), which has an adverse effect on the treatment. The existing patch-type insulin pump does not currently have the function of detecting the amount of injected medicine, which affects the user experience. Summary of the invention

DETAILED DESCRIPTION
[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0032] The insulin injection system provided by the embodiment of the present application comprises an operating device and a patch type insulin pump, and the operating device can be used for controlling the patch type insulin pump, so as to detect the amount of medicine injected in the patch type insulin pump and realize the automatic injection of the patch type insulin pump. In actual application, the operating device can be, for example, an operating program arranged on a smart phone, and the user controls the patch type insulin pump by clicking on the different options in the operating program. Below in conjunction with specific embodiment, above-mentioned patch type insulin pump is described in detail.
[0033] refer to Figure 1 The patch-type insulin pump in this embodiment may include an injection module 100, a power module 200 and an injection detection module 300, wherein the user can inject the medicine in the medicine bottle into the injection module 100, and then inject the medicine into the body through the injection module 100, the power module 200 and the injection detection module 300 can be used together to detect the amount of injected medicine, and the power module 200 can also be used to inject the medicine in the injection module 100 into the user's body.
[0034] Specifically, refer to Figure 2The injection module 100 may include a medicine storage tank 110, a push rod piston 120 and two conductive push rods 130. The bottom of the medicine storage tank 110 is provided with a medicine injection port 111 connected to the inside of the medicine storage tank 110. The user can inject the medicine in the medicine bottle into the medicine storage tank 110 through the medicine injection port 111. The top of the medicine storage tank 110 is provided with an opening, and the push rod piston 120 sealing cover is set at the opening. At this time, the bottom of the push rod piston 120 cooperates with the space inside the medicine storage tank 110 to form a medicine storage space, and the push rod piston 120 can also ensure that the medicine in the medicine storage space will not flow out from the opening. Let the first direction be the arrangement direction from the top to the bottom of the medicine storage tank 110, and let the second direction be the arrangement direction from the bottom to the top of the medicine storage tank 110. The push rod piston 120 can also move relative to the medicine storage tank 110 along the first direction to change the size of the medicine storage space.
[0035] The two conductive push rods 130 can be respectively connected to the side of the push rod piston 120 away from the injection port 111, each conductive push rod 130 can extend along the first direction, and the two conductive push rods 130 can be arranged at intervals. When the injection module 100 is in the initial state, the bottom of the push rod piston 120 can contact the bottom wall. When the user injects the medicine into the medicine storage tank 110 through the injection port 111, the push rod piston 120 moves away from the injection port 111 under the push of the medicine, and at the same time drives the conductive push rod 130 to move away from the injection port 111.
[0036] Continue to refer Figure 2 The injection detection module 300 may include a control circuit board 310, two conductive contact springs 320 and a conductive module 330. The two conductive contact springs 320 are electrically connected to the control circuit board 310 respectively. For example, the conductive contact springs 320 may be fixed to the control circuit board 310 by welding, screw fastening, riveting, laser welding or by connecting an electrical connection element. The two conductive contact springs 320 are arranged at intervals, and the two conductive contact springs 320 are in sliding contact with the two conductive push rods 130 respectively, that is, each conductive push rod 130 is always in contact with the conductive contact spring 320 during the movement along the first direction. The conductive contact spring 320 may have a certain elasticity. When the conductive push rod 130 moves relative to the conductive contact spring 320, the conductive contact spring 320 may produce a certain deformation and accumulate force, so that the conductive contact spring 320 and the conductive push rod 130 can always maintain contact.
[0037] The conductive module 330 is located on the side of the conductive push rod 130 away from the push rod piston 120. The conductive module 330 is connected to the power module 200. The power module 200 can drive the conductive module 330 to move along the first direction until the conductive module 330 contacts the two conductive push rods 130 at the same time. At this time, the control circuit board 310, the two conductive contact springs 320, the two conductive push rods 130 and the conductive module 330 form a closed loop, and the current in the loop can flow normally, thereby generating a continuous electrical signal. The control circuit board 310 is connected to the power module 200 by signal. The control circuit board 310 can receive electrical signals and generate signals for controlling the working state of the power module 200, thereby driving the power module 200 to start or stop working.
[0038] Continue to refer Figure 2 The power module 200 includes a drive module (see Figure 2 The power module 200 is a power module 200, which is denoted by the reference numeral 210, a transmission module 220, a bracket 230, a lead screw 240 and a slider 250, wherein the lead screw 240, the drive module and the transmission module 220 can be installed on the bracket 230 to make the overall structure of the power module 200 stable. Specifically, the bracket 230 may include a first support frame 231 and a second support frame 232 arranged in parallel, and a connecting plate 233 connected between the first support frame 231 and the second support frame 232, so that the bracket 230 is a U-shaped structure as a whole. The drive module can be fixed on the connecting plate 233, the transmission module 220 is fixed on the side of the first support frame 231 away from the second support frame 232, the lead screw 240 extends along the first direction, that is, the axial direction of the lead screw 240 is consistent with the first direction, and the two ends of the lead screw 240 are respectively penetrated through the first support frame 231 and the second support frame 232.
[0039] Further, the slider 250 can be sleeved on the lead screw 240 and be transmission-connected with the lead screw 240. In addition, the conductive module 330 can be fixed to the side of the slider 250 facing the conductive push rod 130. In this embodiment, the driving module is transmission-connected with the transmission module 220, and the transmission module 220 is transmission-connected with one end of the lead screw 240 that is inserted through the first support frame 231. Thus, the power output by the driving module can be transmitted to the lead screw 240 through the transmission module 220, thereby driving the lead screw 240 to rotate around its own axis relative to the support frame 230. When the lead screw 240 rotates, the slider 250 can be driven to move in the first direction, thereby driving the conductive module 330 to move in the first direction.
[0040] The conductive module 330 is disposed around the circumference of the lead screw 240, and there is a gap between the conductive module 330 and the lead screw 240 to ensure that there is no contact between the conductive module 330 and the lead screw 240. For example, the conductive module 330 may be in a "U" shape or a U shape, so that the lead screw 240 can pass through the hollow part of the conductive module 330 and be connected to the slider 250 through transmission.
[0041] The second support frame 232 is provided with guide holes (not shown) corresponding to the two conductive push rods 130. Each conductive push rod 130 can be inserted into the corresponding guide hole. At this time, the lead screw 240 is located between the two conductive push rods 130, and the lead screw 240 is spaced apart from each conductive push rod 130. When the conductive module 330 moves along the first direction, the conductive module 330 can avoid the lead screw 240 and contact the two conductive push rods 130, thereby forming a closed loop.
[0042] In this embodiment, the conductive module 330 may be, for example, but not limited to, conductive cloth, or the conductive module 330 may be made of metal material to ensure good conductive performance of the conductive module 330. Similarly, the conductive push rod 130 may be made of metal material, which can improve the strength of the conductive push rod 130 while ensuring good conductive performance of the conductive push rod 130, and ensure that the conductive push rod 130 will not deform during movement and affect the contact with the conductive module 330. Similarly, the conductive contact spring 320 may also be made of metal material to ensure good conductive effect between the conductive push rod 130 and the conductive contact spring 320.
[0043] It is worth mentioning that the materials of the bracket 230 and the slider 250 in this embodiment can be non-conductive materials. When the conductive push rod 130 moves along the first direction, the conductive push rod 130 will not generate an electrical signal due to contact with the bracket 230 or the slider 250, thereby interfering with the operation of the control circuit board 310. Therefore, the patch-type insulin pump in this embodiment can not only detect the amount of medicine, but also improve the detection accuracy of the injection amount.
[0044] To facilitate calculation of the amount of medicine injected into the medicine storage tank 110, Figure 2As shown, the driving module can be a stepper motor 210. In this case, the moving distance of the conductive module 330 can be calculated by the total number of rotations of the output shaft of the stepper motor 210 (e.g., when the total moving distance of the conductive module 330 is 10.00 mm, the stepper motor 210 needs to rotate 8000 times, so the displacement of the conductive module 330 after the stepper motor 210 rotates one circle is 0.00125 mm. After the driving module detects the number of rotations C of the stepper motor 210, the total displacement L of the conductive module 330 = C*0.00125 mm), which is simple and convenient. In addition, the drug storage space inside the drug storage tank 110 is a regular three-dimensional shape, for example, the drug storage space is a square or cylindrical structure, so that the amount of medicine injected into the drug storage tank 110 can be calculated by the moving distance of the push rod piston 120. Specifically, when the injection module 100 and the injection detection module 300 are both in the initial state, the bottom of the push rod piston 120 contacts the inner wall of the medicine storage tank 110, indicating that there is no medicine in the medicine storage tank 110, and the amount of medicine stored in the medicine storage tank 110 is 0. At this time, the conductive module 330 and the conductive push rod 130 are out of contact, and the conductive push rod 130 is at the farthest position from the conductive module 330. Then the conductive module 330 is driven to move toward the conductive push rod 130 until it contacts the conductive push rod 130, and the total moving distance of the conductive module 330 along the first direction is L. When the piston push rod is in the middle position in the medicine tank 110, it means that there is a certain amount of medicine in the medicine tank 110. At this time, when the conductive module 330 moves toward the conductive push rod 130 until it contacts the conductive push rod 130, the conductive module 330 moves along the first direction The distance L1, the push rod piston 120 moves in the medicine tank 110 The distance L2, that is, the height of the injected medicine is h=L2=L-L1, and the amount of medicine injected can be calculated according to the shape of the medicine tank 110 through a formula (for example, if the cross-sectional area of the medicine tank 110 is known to be S, and the height of the injected medicine is L2, the total volume V of the injected medicine is obtained by the volume formula V=S*h=S*L2).
[0045] In specific implementation, when the user downloads the corresponding operating program on the smart phone, the operating program and the control circuit board 310 can be connected by wire or wireless connection (for example, by Bluetooth connection) to achieve signal connection. Figure 3 and Figure 4 When the injection module 100 and the injection detection module 300 are both in the initial state, the user injects the medicine from the medicine bottle into the medicine storage tank 110 through the injection port 111, and the push rod piston 120 moves along the lower edge of the medicine under the thrust of the medicine. Figure 3The push rod piston 120 moves away from the injection port 111 in the direction A until the user completes the injection, and then stops moving and remains stationary. At this time, the user can click the "Injection Completed" option in the operation program, and the operation program will send the generated corresponding signal M to the control circuit board 310. The control circuit board 310 generates a signal N based on the received signal M to drive the conductive module 330 to move toward the conductive push rod 130 using the power module, and sends the signal N to the stepper motor 210. After receiving the signal N, the stepper motor 210 starts working, driving the slider 250 and the conductive module 330 along the Figure 4 The conductive module 330 moves in the direction B toward the conductive push rod 130 until both ends of the conductive module 330 are in contact with the two conductive push rods 130. Figure 4 The current at a will flow to b along the conductive push rod 130 and the conductive module 330, generating a continuous electrical signal P. The control circuit board 310 receives the electrical signal P, and generates a signal Q for controlling the stepper motor 210 to stop working according to the electrical signal P, and sends the signal Q to the stepper motor 210 again, so that the stepper motor 210 stops working. The control circuit board 310 can calculate the moving distance of the conductive module 330 along the B direction according to the total number of rotations of the output shaft from sending the N signal to the stepper motor 210 to the stepper motor 210 receiving the P signal and stopping, thereby detecting the amount of medicine injected into the medicine storage tank 110. Finally, the control circuit board 310 sends the injected medicine amount generation signal to the operating program and displays it on the smart phone, so that the user can check the injected medicine amount.
[0046] In some embodiments, the control circuit board 310 in this embodiment can also perform drug dosage control, that is, control the amount of drug injected by the user so that the user can use the drug accurately. Figure 5As shown, the control circuit board 310 can obtain the total number of rotations of the stepper motor 210 C=L / 0.00125 according to the preset medicine volume V ml, the cross-sectional area of the medicine storage tank 110 is known to be S, and the displacement L=V / S that the conductive module 330 needs to move. At this time, the push rod piston 120 is in the initial state. When a certain amount of medicine is injected into the medicine storage tank 110, the push rod piston 120 moves a distance h1 in the medicine storage tank 110. Then, according to the moving distance h2 of the conductive module 330 when the conductive module 330 moves toward the conductive push rod 130 until it contacts the conductive push rod 130 when the injection module 100 and the injection detection module 300 are both in the initial state, the distance h=h2-h1 that the conductive module 330 moves from the initial position to the preset position is calculated. That is to say, in this embodiment, the conductive module 330 can be first moved toward the conductive push rod 130 to a preset position, and then the medicine is injected into the medicine storage tank 110. Under the thrust of the medicine, when the conductive push rod 130 moves to contact with the conductive module 330, the conductive push rod 130 cannot move further. At this time, the injection of the medicine stops, thereby ensuring that the amount of medicine injected into the medicine storage tank 110 is constant.
[0047] Based on this, the patch-type insulin pump in this embodiment may also be provided with a buzzer reminder module (not shown in the figure), which is connected to the control circuit board 310 signal. When the conductive module 330 contacts the conductive push rod 130, the control circuit board 310 may generate a signal T. After the buzzer reminder module receives the signal T, a buzzer alarm may be generated, thereby reminding the user that the injection is complete.
[0048] When implementing it, Figure 5 The user can first input a preset medicine amount in the operation program, and the operation program generates a corresponding signal U based on the preset medicine amount, and sends the signal U to the control circuit board 310. The control circuit board 310 calculates the distance h that the conductive module 330 needs to move according to the preset medicine amount, and generates a signal V based on it, and sends the signal V to the stepper motor 210 to drive the stepper motor 210 to work and make the conductive module 330 move along Figure 5 The stepper motor 210 stops working at the preset position h in the direction of C in the figure. Then the user injects the medicine into the medicine storage tank 110 from the medicine injection port 111. The medicine pushes the push rod piston 120 to move toward the conductive module 330 until it contacts the conductive module 330. At this time, the current at a will flow along the conductive push rod 130 and the conductive module 330 to b, generating a continuous electrical signal W. The control circuit board 310 receives the electrical signal W and generates a signal T according to the electrical signal W, so that the buzzer reminder module sounds an alarm to remind the user that the required volume of medicine has been injected. At the same time, the user cannot push the conductive module 330 to move, thereby ensuring that the user injects the exact amount of medicine required.
