Description

Technical Field

[0001] The invention relates to the technical field of injection positioning devices, in particular to a hypoglycemic drug injection positioning device. Background Art

[0002] The injection positioning device is an auxiliary tool used to help medical staff or patients accurately locate the injection site during injection. For example, diabetic patients will use a plate-shaped positioning device for auxiliary positioning when injecting hypoglycemic drugs. The positioning device can help users determine the correct injection position, avoid misoperation or repeated injections in the same area, thereby improving the accuracy and safety of injections.

[0003] At present, the existing positioning device has a large coverage area during use, which will cover the entire front of the abdomen, and only has multiple injection holes. When the patient injects the drug, after each injection of the skin under a hole, the next injection of the drug needs to be switched to the skin under another hole. Therefore, when it is necessary to inject the skin under a hole at a non-edge position, the patient cannot lift the skin around the injection site due to the large coverage area of ​​the positioning device. This makes it easy for some patients with low body fat to inject the drug into the muscle layer.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing hypoglycemic drug injection positioning devices on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, which makes it impossible to achieve the desired effect.

The front of the block 2120 penetrates the transmission gear 2122 and extends to the front of the transmission gear 2122. The outer surface of the block 2120 is engaged with the inside of one of the holes 2119. By providing the transmission gear 2122, the first force spring 2128 and the block 2120, the first force spring 2128 can be used to push the block 2120 to move toward the inside of the hole 2119, thereby limiting the transmission gear 2122.

[0050] See also Fig.18 A second force spring 2118 is fixedly connected to the front of the second rectangular plate 2112, and a circular plate 2113 is fixedly connected to the end of the second force spring 2118 away from the second rectangular plate 2112.

[0051] See also Fig.18 and Fig.19The inner wall of the first rectangular plate 2111 and the inner wall of the second rectangular plate 2112 are jointly rotatably connected with a first rotating shaft 2126, and the outer surface of the first rotating shaft 2126 is fixedly connected with a first rotating block 2127, and the outer surface of the first rotating block 2127 contacts the outer surface of the transmission gear 2122. The back of the second rectangular plate 2112 is respectively fixedly connected with a first fixed plate 2123 and a first limiting plate 2125, and the bottom surface of the first fixed plate 2123 and the upper surface of the first rotating block 2127 are jointly fixedly connected with a first return spring 2124, and the bottom surface of the first limiting plate 2125 contacts the upper surface of the first rotating block 2127. By providing the first rotating block 2127 and the first rotating shaft 2126, the first rotating shaft 2126 can drive the first rotating block 2127 to rotate, and the first limiting plate 2125 can limit the rotation direction of the first rotating block 2127, thereby determining the rotation direction of the transmission gear 2122.

[0052] See also Fig.17 and 18 The back of the transmission gear 2122 is fixedly connected to a long plate 2114, the inner wall of the long plate 2114 is rotatably connected to a clamping shaft 2116, the outer surface of the clamping shaft 2116 is fixedly connected to a connecting pad 2115, and the left side of the connecting pad 2115 is fixedly connected to the right side of the first rectangular box 1. By providing the long plate 2114, the clamping shaft 2116 and the connecting pad 2115, the connecting pad 2115 can be used to connect the clamping shaft 2116 and the first rectangular box 1, and by utilizing the good flexibility of the connecting pad 2115, the first rectangular box 1 can be tightly attached to the patient's skin surface.

[0053] See also Fig.17 and Fig.18 The interior of the long plate 2114 is clamped with a clamping ring 2117, and the interior of the clamping ring 2117 is clamped with the outer surface of the clamping shaft 2116. By providing the clamping ring 2117, the clamping shaft 2116 can be limited by the clamping ring 2117.

[0054] The specific implementation of this embodiment is as follows: when the device is needed, the injection device carrying the medicine can be inserted into the interior of the movable plate 301 and the positioning frame 2203, and when the injection device enters the interior of the movable plate 301 and the positioning frame 2203, it will contact the first rotating cylinder 307, the second rotating cylinder 304 and the third rotating cylinder 303. The surfaces of the first rotating cylinder 307, the second rotating cylinder 304 and the third rotating cylinder 303 are all made of rubber, so they have a certain friction and flexibility, so they can provide a temporary squeezing force to the injection device to fix the injection device, and when the injection device extends to the rear of the positioning frame 2203, it is necessary to manually move the squeezing shaft 322 so that the squeezing shaft 322 is on one side of the injection device. After the extrusion shaft 322 loses the pulling force, the extrusion shaft 322 will contact one side of the injection device due to gravity. At this time, the patient needs to press the circular plate 2113 to make the circular plate 2113 completely engage in the six engaging holes 2119. It should be understood that when the circular plate 2113 is not subjected to the pressing force, although it is still engaged in the six engaging holes 2119, it cannot completely fill the internal space of the six engaging holes 2119. When the circular plate 2113 is subjected to the pressing force, the space inside the engaging holes 2119 can be filled. At this time, the engaging block 2120 engaged in one of the engaging holes 2119 can be pushed out, and then the long plate 2114 can be rotated. It should be understood that the long plate 2114 is fixed to the back of the transmission gear 2122. The outer surface of the transmission gear 2122 is in contact with the first rotating block 2127, and the upper surface of the right half of the first rotating block 2127 is in contact with the first limiting plate 2125. Therefore, the right half of the first rotating block 2127 can only rotate downward, so the transmission gear 2122 can only rotate counterclockwise under the joint action of the first rotating block 2127 and the first limiting plate 2125. When the transmission gear 2122 and the long plate 2114 rotate forty-five degrees, the block 2120 will be engaged with the inside of the next hole 2119. At this time, the positioning frame 2203 and the internal injection device are positioned to the skin where the injection is to be made this time. It should be understood that the six holes 2119 opened on the front of the second rectangular plate 2112 are evenly distributed. On both sides of the second rectangular plate 2112, the angle difference between the two adjacent clamping holes 2119 on the same side is forty-five degrees. At this time, the long plate 2114 will be in a state of tilting forty-five degrees. Here, the clamping ring 2117 needs to be pulled out, and then the clamping shaft 2116 is controlled to rotate forty-five degrees clockwise, and then the clamping ring 2117 is clamped inside the long plate 2114. At this time, the clamping shaft 2116 will be clamped in the triangular clamping groove located above the clamping ring 2117. Therefore, it can be understood that the angle between the three triangular clamping grooves opened on the surface of the clamping ring 2117 is also forty-five degrees. At this time, the first rectangular box 1 and the second rectangular box 2202 are parallel to the ground, and then the fixing belt 2110 can be used to tightly fix the entire device on the patient's stomach.Then, the first pressing plate 2101 and the second pressing plate 2201 are pressed downward at the same time. The first pressing plate 2101 will push the two first transmission shafts 2102 downward after being pressed. The downward movement of the first transmission shaft 2102 will drive the first tooth plate 2106 to move downward, and there is a meshing relationship between the first tooth plate 2106 and the first gear 2107, and there is also a meshing relationship between the first gear 2107 and the second tooth plate 2103. Therefore, the second tooth plate 2103 and the first squeezing plate 2104 will move upward under the transmission of the first gear 2107. At the same time, the two first transmission plates 2108 fixed on the outer surface of the first transmission shaft 2102 will also push the second squeezing plate 2105 to move downward, thereby squeezing and stacking the skin between the second squeezing plate 2105 and the first squeezing plate 2104 together, and the positions between the first squeezing plate 2104 and the second squeezing plate 2105 that contact the skin are covered with a rubber layer to avoid squeezing injuries to the patient.

[0055] Example 2: Please refer to Figure 1-Figure 6 The present invention provides a technical solution: a hypoglycemic drug injection positioning device. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The adjustment mechanism 2 also includes an angle adjustment unit 22, which is arranged above the first rectangular box 1. The angle adjustment unit 22 cooperates with the skin squeezing unit 21, and the angle adjustment unit 22 can adjust the angle during injection.

[0056] As a further limitation of the adjustment mechanism 2 of the present invention, the angle adjustment unit 22 includes a second rectangular box 2202, the back of the second rectangular box 2202 is fixedly connected to the front of the first rectangular box 1, the outer surface of each first gear 2107 is rotatably connected to the inner wall of the second rectangular box 2202, the front of each T-shaped limit block 2109 is fixedly connected to the back of the second rectangular box 2202, the inner wall of the second rectangular box 2202 is rotatably connected to two threaded shafts 2207, and the outer surface of each threaded shaft 2207 is threadedly connected The rectangular blocks 2209 are connected, and the front and back of each rectangular block 2209 are in contact with the inner wall of the second rectangular box 2202. The inner wall of one rectangular block 2209 is rotatably connected to the fixed shaft 2206, and the left side of the other rectangular block 2209 is fixedly connected to the gearbox 2211. The input end of the gearbox 2211 is fixedly connected to the second transmission shaft 2213, and the outer surface of the second transmission shaft 2213 is fixedly connected to the second gear 2205. The output end of the gearbox 2211 is fixedly connected to the third transmission shaft 2213. The transmission shaft 2210, the left end of the third transmission shaft 2210 and the right end of the fixed shaft 2206 are fixedly connected to the positioning frame 2203, the inner bottom wall of the second rectangular box 2202 is fixedly connected to the third tooth plate 2212, the outer surface of the third tooth plate 2212 is meshed with the outer surface of the second gear 2205, the top of each threaded shaft 2207 is fixedly connected to a spiral ring 2208, the outer surface of each spiral ring 2208 is rotatably connected to the inner wall of the second rectangular box 2202, and the interior of each spiral ring 2208 is slidably connected to the inner wall of the second rectangular box 2202. A spiral shaft 2204 is connected, and the top end of each spiral shaft 2204 passes through the second rectangular box 2202 and extends to the top of the second rectangular box 2202. The top ends of the two spiral shafts 2204 are commonly fixedly connected with a second pressing plate 2201. By setting an angle adjustment unit 22, the angle of insulin injection can be adjusted by using the angle adjustment unit 22. The angle adjustment unit 22 and the skin squeezing unit 21 cooperate with each other, which can effectively avoid the problem that the patient will inject insulin into the muscle layer during the use of the device.

[0057] The specific implementation of this embodiment is as follows: when the second pressing plate 2201 is pressed downward, it will push the spiral shaft 2204 to move downward synchronously, and the spiral shaft 2204 is slidably connected to the inside of the spiral ring 2208, so the spiral ring 2208 will rotate. It should be understood here that the spiral groove on the inner wall of the spiral ring 2208 corresponds to the spiral strip fixed on the outer surface of the spiral shaft 2204, and the spiral ring 2208 rotates on the inner wall of the second rectangular box 2202. Therefore, as the spiral shaft 2204 continues to move, the spiral groove on the inner wall of the spiral ring 2208 will rotate along the spiral strip pattern on the surface of the spiral shaft 2204. When the spiral ring 2208 rotates, it will transmit power to the threaded shaft 2207, and the threaded shaft 2207 is a hollow structure, so the spiral shaft 2204 can pass through the spiral ring 2208 and enter the inside of the threaded shaft 2207, thereby driving the threaded shaft 2207 to rotate, causing the two rectangular blocks 2209 threadedly connected on the outer surface of the threaded shaft 2207 to move downward. The rectangular block 2209 moves downward, which will drive the fixed shaft 2206, the gear box 2211, the second transmission shaft 2213, the second gear 2205, the third transmission shaft 2210 and the positioning frame 2203 to move downward synchronously, and the second transmission shaft 2213 fixed at the input end of the gear box 2211 will rotate due to the meshing relationship between the second gear 2205 and the third tooth plate 2212, so that the power can be transmitted to the gear box 2211, and the slower power can be transmitted to the third transmission shaft 2210 through the gear speed change structure inside the gear box 2211, so that the positioning frame 2203 can be driven to rotate, and due to the existence of the gear box 2211, when the positioning frame 2203 moves downward to the farthest distance, the positioning frame 2203 will also rotate forty-five degrees, so as to ensure that the positioning frame 2203 is always aligned with the skin piled up between the second extrusion plate 2105 and the first extrusion plate 2104, and then the injection device can be pushed to perform the injection.

[0060] The specific implementation of this embodiment is as follows: after the drug injection is completed, the patient will pull the injection device outward, and at this time, the third rotating cylinder 303 located at the upper part of the movable plate 301 cannot rotate in the opposite direction, because the third gear 311 is fixed to the surface of the third rotating cylinder 303 located at the upper part, and the third gear 311 is in contact with the second rotating block 316, and the back side of the second rotating block 316 is in contact with the front side of the second limiting plate 314, so the second rotating block 316 rotates toward the position of the second reset spring 313, so the third gear 311 can only rotate in the clockwise direction and cannot rotate in the reverse direction. 301 is moved outward synchronously, so that the moving plate 301 is out of contact with the positioning frame 2203, thereby driving the second transmission plate 302 fixed on the back of the moving plate 301 to move, until the four support frames 309 fixed on the two sides of the second transmission plate 302 move out of the inside of the force block 310, at which time the push plate 308 and the force block 310 lose their supporting force and move downward, and as the second transmission plate 302 continues to move, the two T-shaped support frames 309 fixed on the back of the second transmission plate 302 are moved out of contact with the positioning frame 2203. The roller 323 rotating on the inner wall of the T-shaped block 319 and the T-shaped block 319 will press the push plate 308 downward, and at this time, the push plate 308 will be in close contact with the outer surface of the first rotating cylinder 307. As the injection device continues to be pulled, the injection device will drive the first rotating cylinder 307 to rotate, so that the first rotating cylinder 307 can be used to push the push plate 308 and the rotating shaft 320 to the injection position of the skin for extrusion. It should be understood here that the center of gravity of the rotating shaft 320 is at the bottom of the squeezing block 317. Therefore, when the injection device is pulled out, the rotating shaft 320 will be between the squeezing block 317 and the gravity block 317. The extrusion block 317 returns to its original position under the action of the force, and the center of gravity of the extrusion block 317 is at the bottom, so the extrusion block 317 will always be perpendicular to the ground, thereby completing the extrusion work on the injection position. When the extrusion is completed, the device can be disassembled, and the injection device can be pushed out from between the second extrusion plate 2105 and the first extrusion plate 2104, and then the first pressing plate 2101 and the second pressing plate 2201 are pulled to reset, and then the positioning frame 305 is pulled to move to the innermost of the rectangular groove 306, and after lifting it upwards, it is inserted into the second transmission plate 302 and waits for the next use.
