Description

Technical Field

In the past 20 years, the incidence of type 1 diabetes in children under 15 years old in China has increased nearly 4 times. Currently, type 1 diabetes accounts for more than 90% of childhood diabetes.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0033] According to the concept of this application, Figures 1 to 6 The embodiment of the device for self-simulation of insulin injection is described below. Specifically, the device for self-simulation of insulin injection is constructed as a split structure, which has three components, namely, a positioning plate 1, a skin-pinching component 6, and a reflective component 9. By wearing the positioning plate 1 on the child's waist, the action of injecting into the child's waist during the injection simulation improves the authenticity of the simulation. At the same time, by setting the skin-pinching component 6, the skin of the child's injection part can be automatically lifted outward before the injection. Since it acts directly on the child, the child can intuitively feel the thickness and touch of the belly being lifted, thereby reducing the occurrence of operational errors when the child operates by himself in the future.

[0034] Please refer to Figures 1 to 6 , a device for self-simulating insulin injection, comprising: a positioning plate 1, a skin-pinching component 6 and a reflective component 9;

[0035] Adjustment components 2 are fixed on both sides of the positioning plate 1, and a waist belt 4 is fixed to one end of the adjustment component 2 away from the positioning plate 1, a navel positioning hole 101 penetrating the positioning plate 1 is provided in the middle of the positioning plate 1, and at least one injection groove 102 is provided on the outside of the navel positioning hole 101, a cylindrical block 5 is slidably provided on the inner side of the injection groove 102, and the moving path of the cylindrical block 5 is the same as the path of the injection groove 102, and two groups of skin-pinching components 6 are symmetrically provided about the vertical central axis of the cylindrical block 5, and a nut 7 is threadedly connected to one side of the cylindrical block 5 away from the positioning plate 1;

[0036] The skin-pinching component 6 includes an oil pipe 61, a sliding block 62 and an extrusion block 63. The oil pipe 61 is fixed on both sides of the cylindrical block 5, and the sliding block 62 is slidably provided at one end of the oil pipe 61 close to the nut 7, and the extrusion block 63 is slidably provided at the other end of the oil pipe 61. A support plate 8 is provided at the lower end of the positioning plate 1, and a reflective component 9 is slidably provided at the upper end of the support plate 8.

[0037] When in use, the belt 4 is wrapped around the child's waist, and then the belt 4 is fixed to the positioning plate 1 by adjusting the component 2, and the position of the navel positioning hole 101 is adjusted so that its central axis is aligned with the child's navel. At this time, the positioning plate 1 is located around the child's navel, and then the side of the cylindrical block 5 with the skin-pinching component 6 is placed in the injection groove 102 until the skin-pinching component 6 fits the child's belly, and then the nut 7 is sleeved on the end of the cylindrical block 5 away from the skin-pinching component 6, and then the nut 7 is rotated inwardly so that the nut 7 moves along the cylindrical block 5 toward the belly. The skin-pinching assembly 6 is symmetrically arranged about the central axis of the cylindrical block 5, so that the two squeezing blocks 63 slide toward each other, and the friction between the squeezing blocks 63 and the belly drives the belly corresponding to the cylindrical block 5 to bulge outward, thereby increasing the thickness of the subcutaneous tissue and preventing insulin from being injected into the muscle layer. The nut 7 is rotated until the side wall of the nut 7 fits with the side wall of the positioning plate 1, so that the skin of the child is pinched directly on the belly, so that real tactile feedback can be provided, and the simulation of pinching the skin can strengthen the child's memory point, and the nut seat 7 can be repeatedly loosened to weaken the inward restriction force of the squeezing block 63 on the belly, and the squeezing block 63 slides toward the end away from the cylindrical block 5 through the outward expansion of the belly, so that the squeezing block 63 and the sliding block 62 are reset, and then the nut 7 can be tightened again, and repeatedly squeezed to improve the operation proficiency. After the nut 7 is tightened on the outer wall of the positioning plate 1, the cylindrical block 5 is fixed to the corresponding injection position on the positioning plate 1, and then the child can insert the insulin syringe into the inner side of the cylindrical block 5 to simulate the real injection process to help students adapt to the psychological pressure during injection and reduce the fear. At the same time, the cylindrical block 5 is perpendicular to the positioning plate 1, so that the insulin syringe is perpendicular to the belly during injection. At this time, the angle at which the child's hand holds the syringe is the correct injection posture, which is conducive to the child remembering the correct grip posture and enhancing muscle memory.

[0038] At this time, after the application is worn on the belly of a child, if one wants to directly observe the injection site, one needs to observe in front of a mirror. However, when the same teaching is given to multiple children, due to the low patience of the children, when they are queuing to observe, the children are prone to lose interest and become distracted. At this time, the support plate 8 and the reflective component 9 are fixed to the front end of the positioning plate 1, and the position of the cylindrical block 5 is reflected to the human eye through the reflective component 9 by utilizing the principle of light reflection, so that the children can observe the position of the cylindrical block 5 conveniently. The support plate 8, the reflective component 9 and the positioning plate 1 are detachable structures, and the support plate 8 and the reflective component 9 can be fixed to the positioning plate 1 when in use, which can not only reduce the weight of the positioning plate 1 during the early injection simulation, but also can be assembled when the injection site of the syringe needs to be observed later, so that multiple children do not interfere with each other. At the same time, the children can directly observe the injection process of the syringe, which can alleviate their fear and anxiety to a certain extent.

[0039] Please refer to Figure 1 to Figure 2 The upper end of the positioning plate 1 can be fixed to the arc-shaped belt 3 by Velcro, and the positioning plate 1 and the arc-shaped belt 3 are both made of cowhide. Compared with cotton cloth, it has a certain hardness and can also fit the skin of children. The leather can maintain the original shape and position of the positioning plate 1, the navel positioning hole 101 and the injection groove 102, and will not be easily deformed. The arc-shaped belt 3 indicates the farthest distance that the upper end of the navel can be injected.

[0040] Please refer to Figure 1 to Figure 2 The adjustment component 2 includes an elastic band 21, a heart-shaped hook 22, an edge band 23 and a heart-shaped buckle 24. Multiple elastic bands 21 are equidistantly fixed on both sides of the positioning plate 1, and a heart-shaped hook 22 is fixed at one end of the elastic band 21 away from the positioning plate 1. Edge bands 23 are symmetrically arranged on both sides of the positioning plate 1, and multiple heart-shaped buckles 24 adapted to the heart-shaped hooks 22 are equidistantly arranged on the side walls of the edge bands 23.

[0041] When in use, the belt 4 is wrapped around the child's waist, and then the positioning plate 1 and the edge belt 23 are dragged to the child's belly. At this time, the elastic band 21 and the edge belt 23 are both located at the front end of the child, which is convenient for the child to fix the heart-shaped hook 22 and the heart-shaped buckle 24, and then the elastic band 21 is pushed outward, and the heart-shaped hook 22 is hung on the heart-shaped buckle 24, and there are multiple heart-shaped buckles 24 arranged at equal intervals, so that during the buckling process, the heart-shaped hook 22 is buckled on different heart-shaped buckles 24, and the space enclosed by the positioning plate 1, the adjustment component 2 and the belt 4 is adjusted to adapt to children with different waist circumferences, so as to improve the practicality of the present application. At the same time, if the child's waist circumference is too large, the positioning plate 1 is easily over-stretched, causing the injection groove 102 on the positioning plate 1 to deform, thereby causing.

[0042] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 The outer side of the cylindrical block 5 is provided with a thread groove 51 adapted to the nut 7, and the nut 7 is connected to the cylindrical block 5 through threads to form a disassembly structure;

[0043] Since the multiple injection grooves 102 are not interconnected, when adjusting the position of the cylindrical block 5, after multiple injections in one injection groove 102, the nut 7 can be removed and the injection groove 102 can be moved to the remaining injection grooves 102, so as to facilitate use. At the same time, the cylindrical block 5 does not need to be disassembled after the experience is completed. Since multiple injections cannot be made in the same position, the position of the cylindrical block 5 can be used to conveniently remind children of the last injection position during the next injection, and then adjustments can be made to facilitate memory. At the same time, the injection groove 102 is in the shape of a long strip, so that when adjusting the cylindrical block 5, it can slide along the injection groove 102, and the two ends of the injection groove 102 are the edge positions of the injection point.

[0044] Please refer to Figure 4 and Figure 5 The end of the extrusion block 63 close to the belly is fixed with a massage head 603, and the massage head 603 includes a baffle 631 and a rubber roller 632, and the end of the extrusion block 63 away from the oil pipe 61 is fixed with a baffle 631, and the end of the baffle 631 away from the extrusion block 63 is fixed with a rubber roller 632;

[0045] During use, when kneading the skin, the two squeezing blocks 63 move toward each other, and at this time, by driving the massage head 603 to move inward, the baffle 631 and the rubber roller 632 push the skin tissue between the two massage heads 603 to move inward and form a bulge, and the baffle 631 is used to increase the contact area between the massage head 603 and the skin, which can disperse the massage force and reduce the pressure on the skin, thereby improving comfort. At the same time, the contact surface between the rubber roller 632 in the massage head 603 and the skin is designed to be an arc surface with a smooth edge, which is conducive to reducing the pressure or discomfort on the skin, thereby further improving the comfort of the massage head 603, and at the same time, the massage head 603 is positioned On both sides of the cylindrical block 5, the syringe and the cylindrical block 5 are coaxially arranged, so that when the massage head 603 moves inward, the belly at the corresponding position of the cylindrical block 5 will bulge toward the side close to the cylindrical block 5, and the highest point of the bulge corresponds to the needle of the syringe. During this process, the nut 7 always squeezes the skin-pinching component 6, so that the belly always has a bulge. After the syringe is completed, the needle should stay under the skin for 6-10 seconds, and the skin needs to be pinched all the time during this process. Since the belly is in a pinching state before the nut 7 is unscrewed, during the teaching process, the children can be taught to stop the skin-pinching action by unscrewing the nut 7 after the needle is pulled out, and the step of unscrewing the nut 7 can deepen the children's memory.

[0046] Please refer to Figure 1 and Figure 3A limiting plate 81 is fixed to one end of the support plate 8 close to the positioning plate 1, and a sliding groove 82 is provided on the upper end surface of the support plate 8, a movable plate 83 is slidably provided on the upper end of the sliding groove 82, and first threaded seats 85 penetrating the movable plate 83 are provided at both ends of the movable plate 83, and the inner side of the first threaded seat 85 is threadedly connected to a first threaded rod 84.

[0047] When in use, the limiting plate 81 is placed on the side of the positioning plate 1 close to the skin, and then the support plate 8 is set vertically to the child's belly, and the movable plate 83 is slid along the slide groove 82 until the side of the movable plate 83 close to the positioning plate 1 is in contact with the outer wall surface of the positioning plate 1, and the first threaded rod 84 is tightened on the inner side of the first threaded seat 85 by threading until the end of the first threaded rod 84 is against the positioning plate 1, so that the limiting plate 81 and the movable plate 83 clamp the positioning plate 1, thereby fixing the support plate 8 directly below the positioning plate 1. At the same time, the longitudinal section of the limiting plate 81 is larger than the longitudinal section of the support plate 8. The contact area between the support plate 8 and the child's belly is increased by the limiting plate 81, thereby improving the support of the belly to the support plate 8, thereby limiting the angle of the support plate 8 with the positioning plate 1, and reducing the situation where the support plate 8 reverses at a large angle, which is beneficial to improving the stability of the support plate 8.

[0048] Please refer to Figure 3 A lifting frame 10 is fixed to one end of the support plate 8 away from the positioning plate 1, and a rotating seat 11 is fixed to the upper end of the lifting frame 10;

[0049] The reflective assembly 9 includes a reflector 91, a sliding seat 92, a lifting rod 93 and a positioning seat 94, and the reflector 91 is rotatably connected to the outer side of the rotating seat 11, the end of the reflector 91 away from the rotating seat 11 is rotatably connected to the lifting rod 93, and the lower end of the lifting rod 93 is slidably connected to the sliding seat 92, and the outer wall of the sliding seat 92 is fixed with a positioning seat 94.

[0050] When in use, the two ends of the reflector 91 are respectively hinged on the upper ends of the rotating seat 11 and the lifting rod 93. Due to the difference in children's reminders and the different distances between the eyes and the navel, the children can adjust the angle of the reflector 91 according to their own situation when in use. During adjustment, the positions of the lifting frame 10 and the rotating seat 11 are fixed, and then the reflector 91 is rotated with the central axis of the rotating seat 11 as the center, and then the sliding seat 92 is driven to slide along the slide groove 82 until the user can directly observe the position of the cylindrical block 5 when lowering his head, so that adaptive adjustment can be made according to the different reminders of the user. At the same time, since each child has a corresponding reflector 91 for observation, it is helpful to reduce the time of queuing for use, and the children's simulation interest can be improved through self-assembly by the children.

[0051] Please refer to Figure 6The positioning seat 94 includes a second threaded rod 941, a second threaded seat 942 and a limiting groove 943. The side wall of the slide groove 82 is provided with a limiting groove 943 that penetrates the support plate 8, and a second threaded seat 942 is slidably provided on the inner side of the limiting groove 943. The inner side of the second threaded seat 942 is threadedly connected to the second threaded rod 941.

[0052] When adjusting the position of the sliding seat 92, the sliding seat 92 passes through the limiting groove 943 and the moving path of the sliding seat 92 is the same as the path of the limiting groove 943. When adjusting, the second threaded rod 941 is loosened to reduce the friction between the second threaded seat 942 and the positioning seat 94. After the positioning seat 94 moves to a suitable position, the second threaded rod 941 is tightened on the inner side of the second threaded seat 942. During the tightening process, the second threaded rod 941 is driven to move toward one end close to the positioning seat 94 until the second threaded rod 941 fits against the outer wall of the positioning seat 94, thereby increasing the friction between the second threaded seat 942, the second threaded rod 941 and the positioning seat 94, and the friction force is used to fix the relative position of the positioning seat 94 in the slide groove 82, so that there is no need for subsequent adjustment by hand, which is convenient for use.

[0053] The device for self-simulation of insulin injection provided by the present invention is further described below in conjunction with the accompanying drawings and implementation examples.

[0054] When in use, the belt 4 is wrapped around the child's waist, and then the positioning plate 1 and the edge belt 23 are dragged to the child's belly, and the position of the navel positioning hole 101 is adjusted so that its central axis is aligned with the child's navel. At this time, the chicken heart hook 22 is hung on the chicken heart buckle 24, and then the side of the cylindrical block 5 with the skin-pinching component 6 is placed in the injection groove 102 until the skin-pinching component 6 fits the child's belly, and then the nut 7 is put on the end of the cylindrical block 5 away from the skin-pinching component 6, and the nut 7 is rotated inward to move the nut 7 along the cylindrical block 5 to the side close to the belly, thereby forcing the two sliding blocks 62 to slide in the same direction as the nut seat 7, and then the hydraulic oil is squeezed along the oil pipe 61 to the side away from the sliding block 62. The two squeezing blocks 63 are moved sideways and pushed to move toward the side close to the central axis of the cylindrical block 5, and the skin-pinching assembly 6 is symmetrically arranged about the central axis of the cylindrical block 5, so that the two squeezing blocks 63 slide toward each other and drive the massage head 603 to move inward, and the skin tissue between the two massage heads 603 is pushed inward by the baffle 631 and the rubber roller 632 to form a bulge, thereby increasing the thickness of the subcutaneous tissue and preventing insulin from being injected into the muscle layer. As the nut 7 rotates until the side wall of the nut 7 fits with the side wall of the positioning plate 1, the skin is directly pinched on the child's belly, so that real tactile feedback can be provided, and the memory point of the child can be strengthened by simulating this action of pinching the skin;

[0055] At the end of the teaching, when the injection point of the syringe can be observed, the two ends of the reflector 91 are hinged to the upper ends of the rotating seat 11 and the lifting rod 93 respectively, and the angle of the reflector 91 is adjusted according to the child's own situation. Since the positions of the lifting frame 10 and the rotating seat 11 are fixed, the reflector 91 is rotated with the central axis of the rotating seat 11 as the center, and then the sliding seat 92 is driven to slide along the slide groove 82 until the user can directly observe the position of the cylindrical block 5 when lowering his head, and then the positioning seat 94 is fixed by tightening the second threaded rod 941.
