[0034] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides an insulin delivery device, comprising a housing 1: an adjustment mechanism 2 is provided on one side of the housing 1, a buckle mechanism 3 is provided on one side of the adjustment mechanism 2, and a first piston rod 4 is movably installed inside the housing 1;
[0035] like Figure 3 and Figure 4 As shown, the adjustment mechanism 2 includes an internal thread groove 201, a third slide groove 202, a scale 203, a threaded ring 204, a support plate 205, a knob 206, a bearing ring 207 and a slider 208. The internal thread groove 201 is provided on one side of the housing 1, and a third slide groove 202 is provided on one side of the internal thread groove 201. A scale 203 is fixedly installed on one side of the third slide groove 202, a threaded ring 204 is provided on one side of the scale 203, a support plate 205 is threadedly sleeved on one side of the threaded ring 204, a bearing ring 207 is movably connected to one side of the support plate 205, a knob 206 is movably installed on one side of the bearing ring 207, and a slider 208 is fixedly installed inside the bearing ring 207.
[0036] The threaded ring 204 is fixedly mounted on the bottom of the housing 1 , and the scale 203 is fixedly mounted on one side of the housing 1 .
[0037] The knob 206 has a thread inside that fits in with the internal thread groove 201 , and the size of the slider 208 is completely fit in with the third slide groove 202 .
[0038] The bearing ring 207 is movably connected to one side of the housing 1 , the knob 206 is threadedly sleeved on one side of the housing 1 , and the slider 208 is movably connected to the inside of the third sliding groove 202 .
[0039] What needs to be further explained is that: when it is necessary to adjust the length of the needle tube entering the patient's body, the knob 206 is rotated manually. At this time, the knob 206 can rotate forward and backward on one side of the internal thread groove 201, thereby driving the bearing ring 207 and the slider 208 to move on one side of the third slide groove 202 at the same time. After the user adjusts the position of the slider 208 according to the value marked on the scale 203, the first piston rod 4 can only be pushed to the position of the slider 208 inside the shell 1 at most when advancing, and cannot be pushed further, thereby achieving the purpose of controlling the distance that the first piston rod 4 pushes the syringe 306.
[0040] like Figure 5 and Figure 6 As shown, the buckle mechanism 3 includes a chassis 301, a first clamping block 302, a second clamping block 303, a second piston rod 304, a sealing piston 305, a syringe 306, a first positioning ring 307, a spring 308, a second positioning ring 309, a sleeve 310, a limiting ring 311, a limiting groove 312, a first slide groove 313 and a second slide groove 314, the chassis 301 is fixedly installed on one side of the first piston rod 4, one side of the chassis 301 is fixedly connected to the first clamping block 302, one side of the first clamping block 302 is movably connected to the second clamping block 303, one side of the second clamping block 303 is fixedly connected to the second piston rod 304, and the second piston A sealing piston 305 is fixedly connected to one side of the rod 304, and the sealing piston 305 is movably connected to the inside of the syringe 306. A first positioning ring 307 is fixedly connected to one side of the syringe 306. A spring 308 is fixedly connected to the bottom of the first positioning ring 307. A second positioning ring 309 is fixedly connected to one side of the spring 308. The second positioning ring 309 is fixedly installed inside the sleeve 310. The sleeve 310 is movably installed on one side of the limiting ring 311. A limiting groove 312 is provided on one side of the limiting ring 311. A first sliding groove 313 is provided inside the limiting ring 311, and a second sliding groove 314 is also provided inside the limiting ring 311.
[0041] A protrusion is fixedly connected to one side of the sleeve 310 , and the size of the protrusion is completely adapted to the second slide groove 314 and the first slide groove 313 . A hole is opened at the bottom of the sleeve 310 , and the size of the hole is completely adapted to the needle tube at the bottom of the syringe 306 .
[0042] The size of the limiting groove 312 is completely adapted to the slider 208 , and the limiting ring 311 is fixedly installed inside the supporting plate 205 .
[0043] It needs to be further explained that: the side of the sealing piston 305 is provided with a thread, and the inside of the syringe 306 is provided with a thread groove adapted to the sealing piston 305. When the first piston rod 4 is pushed toward the inside of the housing 1, the chassis 301 and the first block 302 will push the second piston rod 304, the sealing piston 305 and the syringe 306 forward as a whole, thereby driving the needle tube into the patient's subcutaneous tissue. At this time, since the sealing piston 305 and the syringe 306 are threadedly connected, the second piston rod 304 and the sealing piston 305 will not directly enter the inside of the syringe 306. When insulin needs to be injected into the body, the first piston rod 4 is rotated counterclockwise to drive the first block 302 to rotate. When the straight surface of the first block 302 contacts the straight surface of the second block 303, the second piston rod 304 and the sealing piston 305 are driven to rotate, thereby pushing the sealing piston 305 into the inside of the syringe 306, and injecting insulin into the patient's body.
[0044] The technical solution provided by the utility model is that when an insulin delivery device is used, first, the support plate 205 is removed from one side of the threaded ring 204 by rotating the support plate 205, and then the sleeve 310 is clamped on one side of the second slide groove 314, and then the first positioning ring 307, the spring 308 and the second positioning ring 309 are placed inside the sleeve 310, and then the syringe 306 storing insulin inside is installed on one side of the first positioning ring 307, and then the syringe 306, the sleeve 310 and the support plate 205 are rotated and installed on one side of the threaded ring 204 again;
[0045] Then, the length of the needle tube to be used is calculated according to the patient's own condition, and after finding the corresponding position on the ruler 203, the bearing ring 207 and the slider 208 are moved to the designated position inside the third slide groove 202 by manually rotating the knob 206 on one side of the internal thread groove 201, and the distance of the needle tube entering the patient's body is adjusted;
[0046] Finally, the first piston rod 4 is manually pushed into the interior of the housing 1. When the first block 302 on one side of the first piston rod 4 contacts the second block 303, the first piston rod 4 continues to move forward, thereby driving the second piston rod 304, the sealing piston 305 and the syringe 306 to move as a whole toward the interior of the sleeve 310. At this time, the needle tube at the bottom of the syringe 306 enters the patient's body through the hole at the bottom of the sleeve 310 until one side of the first piston rod 4 contacts the slider 208 and is restricted from moving. Then, the first piston rod 4 is rotated counterclockwise to drive the first block 302 to rotate. When the straight surface of the first block 302 contacts the straight surface of the second block 303, the second piston rod 304 and the sealing piston 305 are driven to rotate, thereby pushing the sealing piston 305 into the interior of the syringe 306 to inject insulin into the patient's body.
