Abstract
Description
Technical Field
[0001] This invention belongs to the field of hydrogel injector technology, and in particular relates to a hydrogel injector with near-infrared light modulation function. Background Technology
[0002] A hydrogel injector with near-infrared light modulation is a new type of injection device that combines the injectability of hydrogel with the near-infrared light response characteristics for use in biomedical and other fields. It typically consists of a syringe barrel, piston, needle, and special optical systems or optical fibers.
[0003] Traditional hydrogel syringes typically mount near-infrared light directly onto the syringe and use a cannula to encase the near-infrared light within the syringe barrel. This results in near-infrared light only being compatible with syringes of the same size, making it difficult to adapt to syringes of different sizes, thus significantly limiting the use of near-infrared light. Utility Model Content
[0004] The purpose of this invention is to provide a hydrogel injector with near-infrared light adjustment function. By setting up a lifting component, specifically by rotating the threaded knob counterclockwise to release the near-infrared light base, the near-infrared light base can be pushed up or down for adjustment. Simultaneously, the adjustment ring can be pushed to ensure smooth contact with the bottom of the injector body. Once the near-infrared light base is adjusted to the appropriate position, rotating the threaded knob clockwise locks the near-infrared light base in place, thus completing the adjustment. This method can adapt to injector bodies of different sizes, solving the problem that traditional hydrogel injectors typically mount the near-infrared light directly on the injector and use a sleeve to encase the near-infrared light within the injector barrel, resulting in near-infrared light only adapting to injectors of the same size and being difficult to adapt to injectors of different sizes.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a hydrogel injector with near-infrared light modulation function, comprising an injector body and further comprising:
[0007] A clamping mechanism is provided on the outside of the syringe body. The clamping mechanism includes two arc-shaped elastic plates on the outside of the syringe body. A near-infrared light seat is provided on the back of the syringe body, and an interface is provided on the back of the near-infrared light seat.
[0008] A lifting assembly, disposed at the bottom of the near-infrared light base, is used for adjusting the position of the near-infrared light base; and
[0009] A locking assembly is disposed on the back of the near-infrared light base, and the locking assembly is used to lock and fix the near-infrared light base and the lifting assembly after adjustment;
[0010] The near-infrared light base is connected to an external near-infrared light source via an interface, and the arc-shaped elastic plate uses its elasticity to fix the near-infrared light base to the syringe body.
[0011] Furthermore, the near-infrared light base has sliding grooves on both the left and right sides. The lifting assembly includes an adjusting ring located at the bottom of the syringe body. A connecting block is fixedly connected to the back of the adjusting ring. Two vertical rods are fixedly connected to the top of the connecting block. Limiting sliders are fixedly connected to the top of the vertical rods. The bottom of the syringe body is inserted into the adjusting ring, making the syringe body more stable after installation.
[0012] The near-infrared light seat is positioned between two vertical rods, and the bottom of the syringe body is inserted into the adjustment ring.
[0013] Furthermore, the locking assembly includes a connecting bracket fixedly connected to the back of the two vertical rods, and a threaded knob is threadedly connected to the center of the connecting bracket; turning the threaded knob counterclockwise releases the fixing of the near-infrared light base, thereby allowing the near-infrared light base to be adjusted.
[0014] The connecting bracket is used to connect the two vertical rods, and the end of the threaded knob contacts the back of the near-infrared light base.
[0015] Furthermore, two arc-shaped clamping plates are fixedly connected to the inner side of the arc-shaped elastic plate, and several rubber protrusions are fixedly connected to the inner side of the arc-shaped clamping plates. The arc-shaped clamping plates are adapted to the surface of the syringe body, and the surfaces of the rubber protrusions are in contact with the surface of the syringe body. A mounting plate is fixedly connected to the side of the arc-shaped elastic plate facing the vertical rod, and the mounting plate is fixedly connected to the vertical rod by bolts. The mounting plate on the arc-shaped elastic plate is installed on the vertical rod by screws, and the mounting plate can be disassembled. When the elasticity of the arc-shaped elastic plate is insufficient, it is easy to replace it, thereby ensuring the clamping elasticity.
[0016] The arc-shaped elastic plate uses elasticity to apply a pushing force to the arc-shaped clamp, and the arc-shaped clamp is used to clamp and fix the syringe body.
[0017] Furthermore, the limiting slider on the vertical rod is slidably connected inside the groove. The limiting slider is used to limit the near-infrared light seat. The inner ring of the adjusting ring is in contact with the bottom of the syringe body. The adjusting ring cooperates with two arc-shaped elastic plates to wrap the syringe body. After the near-infrared light seat is released from fixation, the adjusting ring can also be pushed and adjusted so that the adjusting ring can smoothly contact the bottom of the syringe body to adapt to syringe bodies of different sizes.
[0018] This utility model has the following beneficial effects:
[0019] 1. This utility model releases the near-infrared light source by turning the threaded knob counterclockwise, then pushes the near-infrared light source up or down for adjustment. At the same time, the adjusting ring can also be pushed to make it smoothly contact the bottom of the syringe body. After the near-infrared light source is adjusted to the appropriate position, the threaded knob is turned clockwise to lock and fix the near-infrared light source, thus completing the adjustment of the near-infrared light source. This method can be adapted to syringe bodies of different sizes.
[0020] 2. This utility model uses an arc-shaped elastic plate. Specifically, the syringe body is inserted between two arc-shaped elastic plates. The elasticity of the arc-shaped elastic plate will clamp and fix the syringe body. The rubber protrusion will contact the surface of the syringe body to increase friction and improve the fixing effect. The arc-shaped elastic plate has an adjustable range when it is opened, so it can clamp and fix syringe bodies of different sizes.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0031] Please see Figures 1-5 As shown, this utility model is a hydrogel injector with near-infrared light modulation function, including injector body 1, and further including:
[0032] The clamping mechanism 2 is located on the outside of the syringe body 1. The clamping mechanism 2 includes two arc-shaped elastic plates 21 located on the outside of the syringe body 1. A near-infrared light seat 22 is located on the back of the syringe body 1. An interface 222 is located on the back of the near-infrared light seat 22.
[0033] A lifting assembly 23 is located at the bottom of the near-infrared light base 22, and is used to adjust the position of the near-infrared light base 22; and
[0034] Locking component 24 is located on the back of near-infrared light base 22. Locking component 24 is used to lock and fix near-infrared light base 22 and lifting component 23 after adjustment. Turning the threaded knob 242 counterclockwise releases the fixation of near-infrared light base 22. Then, push the near-infrared light base 22 up or down for adjustment. At the same time, the adjusting ring 231 can also be pushed for adjustment so that the adjusting ring 231 can smoothly contact the bottom of the syringe body 1. When the near-infrared light base 22 is adjusted to the appropriate position, turn the threaded knob 242 clockwise to lock and fix the near-infrared light base 22, thereby completing the adjustment of near-infrared light base 22. This method can be adapted to syringe bodies 1 of different sizes.
[0035] The near-infrared light seat 22 is connected to an external near-infrared light source through interface 222, and the arc-shaped elastic plate 21 uses its elasticity to fix the near-infrared light seat 22 to the syringe body 1.
[0036] The near-infrared light base 22 has a sliding groove 221 on both the left and right sides. The lifting assembly 23 includes an adjustment ring 231 set at the bottom of the syringe body 1. A connecting block 232 is fixedly connected to the back of the adjustment ring 231. Two vertical rods 233 are fixedly connected to the top of the connecting block 232. A limit slider 234 is fixedly connected to the top of the vertical rods 233.
[0037] The near-infrared light seat 22 is positioned between the two vertical rods 233, and the bottom of the syringe body 1 is inserted into the adjustment ring 231.
[0038] Locking assembly 24 includes a connecting bracket 241 fixedly connected to the back of the two vertical rods 233, and a threaded knob 242 is threadedly connected to the center of the connecting bracket 241;
[0039] The connecting bracket 241 is used to connect the two vertical rods 233, and the end of the threaded knob 242 contacts the back of the near-infrared light base 22.
[0040] Two arc-shaped clamping plates 211 are fixedly connected to the inner side of the arc-shaped elastic plate 21. Several rubber protrusions 212 are fixedly connected to the inner side of the arc-shaped clamping plate 211. The arc-shaped clamping plate 211 is adapted to the surface of the syringe body 1. The surface of the rubber protrusions 212 contacts the surface of the syringe body 1. An mounting plate 213 is fixedly connected to the side of the arc-shaped elastic plate 21 facing the vertical rod 233. The mounting plate 213 is fixedly connected to the vertical rod 233 by bolts. By setting the arc-shaped elastic plate 21, specifically inserting the syringe body 1 between the two arc-shaped elastic plates 21, the arc-shaped clamping plate 211 will clamp and fix the syringe body 1 using the elasticity of the arc-shaped elastic plate 21. The rubber protrusions 212 will contact the surface of the syringe body 1 to increase friction and improve the fixing effect. Moreover, the arc-shaped elastic plate 21 has an adjustment range when it is opened, so it can clamp and fix syringe bodies 1 of different sizes.
[0041] Among them, the arc-shaped elastic plate 21 uses elasticity to apply a pushing force to the arc-shaped clamp 211, and the arc-shaped clamp 211 is used to clamp and fix the syringe body 1.
[0042] The limiting slider 234 on the vertical rod 233 is slidably connected inside the slide groove 221. The limiting slider 234 is used to limit the near-infrared light seat 22. The inner ring of the adjusting ring 231 is in contact with the bottom of the syringe body 1. The adjusting ring 231 cooperates with the two arc-shaped elastic plates 21 to wrap the syringe body 1.
[0043] One specific application of this embodiment is:
[0044] In use, first draw hydrogel into the syringe body 1, then insert the syringe body 1 between two arc-shaped elastic plates 21. The arc-shaped clamp 211 will clamp and fix the syringe body 1 using the elasticity of the arc-shaped elastic plates 211. At the same time, the rubber protrusion 212 will contact the surface of the syringe body 1 to increase friction and improve the fixation effect. Meanwhile, the bottom of the syringe body 1 will be inserted into the adjustment ring 231, so that the syringe body 1 is more stable after installation. After the syringe body 1 is installed with the near-infrared light base 22, the near-infrared light base 22 is connected to the near-infrared light source through the interface 222. Usually, a specific wavelength (commonly 808 nm) of light is provided by an external device (such as a laser or LED). After penetrating the tissue, it acts on the photosensitive component in the hydrogel. Then, the hydrogel can be injected using the syringe body 1.
[0045] After the syringe body 1 is installed with the clamping mechanism 2, the position of the near-infrared light seat 22 can be adjusted according to the size of the syringe body 1. By turning the threaded knob 242 counterclockwise, the near-infrared light seat 22 is released from its fixation. Then, by pushing the near-infrared light seat 22 upward or downward, the limiting slider 234 will slide within the slide groove 221, causing the near-infrared light seat 22 to move linearly. At the same time, after the near-infrared light seat 22 is released from its fixation, the adjusting ring 231 can also be pushed and adjusted so that the adjusting ring 231 smoothly contacts the bottom of the syringe body 1. When the near-infrared light seat 22 is adjusted to the appropriate position, the threaded knob 242 can be adjusted to the appropriate position. Turning knob 242 clockwise locks and secures the near-infrared light base 22, thus completing the adjustment of the near-infrared light base 22. This method can accommodate syringe bodies 1 of different sizes. The arc-shaped elastic plate 21 clamps and secures the syringe body 1 in an elastic manner. The arc-shaped elastic plate 21 has an adjustment range when it is opened, so it can clamp and secure syringe bodies 1 of different sizes. The mounting plate 213 on the arc-shaped elastic plate 21 is installed on the vertical rod 233 with screws. The mounting plate 213 can be removed. When the elasticity of the arc-shaped elastic plate 21 is insufficient, it is easy to replace it, thus ensuring the clamping elasticity.
