Description

Technical Field

[0001] The utility model relates to the technical field of female care appliances, in particular to a device used for injecting PLLA regeneration materials to improve vaginal dryness and aging. Background Art

[0002] Intimate care refers to the care of the female private parts and reproductive system, which can keep or restore the female reproductive system to a healthy and youthful state. Microneedle surgery uses tiny needles to form many tiny channels on the target tissue, stimulating the regeneration of collagen in the target tissue, which can effectively promote metabolism. At the same time, if hollow microneedles are used, the injection of active ingredients can also be achieved through the hollow microneedles.

[0003] Poly-L-lactic acid (PLLA) is a regenerative material that is widely used in the medical field due to its good efficacy and safety. PLLA can achieve anti-aging effects by inducing human fibroblasts to secrete collagen, allowing the newly produced collagen to fill the volume of the original missing part.

[0004] The vagina is a muscular tube composed of mucosa, muscle layer and outer membrane. It is highly stretchable and connects the uterus and external reproductive organs. Vaginal mucosa refers to the mucus membrane layer secreted by the inner wall of the vagina to keep the inner wall of the vagina moist and active. Vaginal aging can cause vaginal dryness. Using microneedle surgery to inject PLLA into the inner wall of the vagina can improve vaginal aging and thus improve vaginal dryness.

[0005] Generally, there is a certain distance between the vaginal walls, maintaining a certain gap. If the gap between the vaginal walls is insufficient and the current microneedle roller is used directly to perform microneedle surgery on the vagina, it will make it difficult for the microneedle roller to roll in the vagina.

[0035] The following describes a device for injecting PLLA regenerative material to improve vaginal dryness and aging according to an embodiment of the utility model with reference to the accompanying drawings.

[0036] See also Figure 1 According to an embodiment of the utility model, the device for injecting PLLA regenerative material to improve vaginal dryness and aging includes a vaginal dilator 1 and a roller needle injector 2. The vaginal dilator 1 is used to increase the distance between the vaginal walls so that the microneedle roller 13 of the roller needle injector 2 can roll in the vagina. The roller needle injector 2 is used to form many fine channels on the inner wall of the vagina, stimulate the regeneration of collagen, and inject PLLA to improve vaginal aging and thus improve vaginal dryness.

[0037] See now Figures 2 to 4 The vaginal dilator 1 includes a plurality of panels 3, a plurality of elastic membranes 4, an adjusting rod 5, an outer sleeve 6, and a plurality of support rod groups. When the panels 3 are in a folded state, they can form an integral tubular structure. The opposite side edges of the two adjacent panels 3 are respectively connected to the opposite side edges of the same elastic membrane 4. The number of the panels 3 is the same as the number of the elastic membranes 4. For example, in this embodiment, the number of the panels 3 is 4, and the number of the elastic membranes 4 is also 4. It should be understood that the number of the panels 3 and the elastic membranes 4 can also be 2, 3, 5, 6, etc., which is not limited by the present invention. When the panels 3 are in a folded state, the elastic membranes 4 are folded inside the panels 3, and the elastic membranes 4 are gradually unfolded during the process of the panels 3 expanding outward. When the distance between the opposite side edges of the two adjacent panels 3 is greater than the width of the elastic membrane 4 naturally unfolded, the elastic membrane 4 can be deformed, so that the vaginal dilator 1 has a wider applicability, that is, the vaginal dilator 1 can increase the distance between the vaginal walls to a large extent. The elastic membrane 4 prevents the side edge of the enclosing plate 3 from scratching the inner wall of the vagina when the vaginal dilator 1 is rotated. The elastic membrane 4 can be a silicone membrane.

[0038] The outer sleeve 6 is arranged on the inner side of the enclosure 3, and the adjustment rod 5 extends into the outer sleeve 6. Preferably, the outer sleeve 6 is generally in the shape of a circular tube, and the adjustment rod 5 is generally in the shape of a cylinder, with a slight gap between the two. Each support rod group supports a enclosure 3 respectively. For example, in this embodiment, the support rod group is composed of two support rods, which are distributed front and back. One end of each support rod 7 is rotatably connected to the adjustment rod 5, and the other end extends out of the outer sleeve 6 through the opening of the wall of the outer sleeve 6 and is rotatably connected to the inner wall of the corresponding enclosure 3. A support 8 is fixed to the outer peripheral wall of the outer sleeve 6, and the support 8 is provided with a sliding rod 10 extending into the longitudinal slot 9 of the support rod 7. When the adjustment rod 5 moves longitudinally relative to the outer sleeve 6, it can cause each enclosure 3 to switch between a retracted state and an expanded state at the same time. For example, Figure 2 As shown in the figure, each of the panels 3 is in a retracted state at the same time. When the adjusting rod 5 moves to the left, the supporting rod 7 causes the panels 3 to expand outward, and the elastic membrane 4 gradually expands. After the panels 3 expand outward to a sufficient distance between the vaginal wall, the elastic membrane 4 is fully expanded. At this time, each of the panels 3 is in a retracted state at the same time. Figure 4 The extended state is shown. For another example, Figure 4 As shown in the figure, each of the panels 3 is in an expanded state at the same time. During the movement of the adjusting rod 5 to the right, the supporting rod 7 causes the panels 3 to be retracted inward, and the elastic membrane 4 is gradually retracted until each of the panels 3 is in the same state as shown in the figure. Figure 2 Shown in collapsed state.

[0039] In this embodiment, the vaginal dilator 1 further includes a hemispherical guide head 11, and the front end of the outer sleeve 6 is connected to the center of the dorsal circular surface of the guide head 11. The front edge of the enclosure 3 is bent and extended inward to form a flange, and when each of the enclosures 3 is in a retracted state, the flange overlaps the periphery of the curved surface of the guide head 11. The flange prevents the front edge of the enclosure 3 from scratching the inner wall of the vagina when the vaginal dilator 1 is rotated or when the vaginal dilator 1 is inserted into the vagina.

[0040] Preferably, when the enclosure panels 3 are in the folded state, the adjustment rod 5 abuts against the dorsal circular surface of the guide head 11 .

[0041] The vaginal dilator 1 may further include a locking member 12. When each of the enclosures 3 is in the expanded state, the outer peripheral wall of the portion of the adjusting rod 5 extending out of the outer sleeve 6 is formed with an external thread, and the locking member 12 is formed with an internal thread that matches the external thread. When each of the enclosures 3 is in the expanded state, the locking member 12 can be rotated to make it abut against the rear end of the outer sleeve 6 to limit the adjustment rod 5 from moving toward the guide head 11, that is, after the vaginal dilator 1 is inserted into the vagina and adjusted to a suitable distance between the vaginal walls, the locking member 12 is used to lock the adjustment rod 5 to prevent the enclosure 3 from being retracted under the pressure of the vaginal walls.

[0042] See now Figure 7 and Figure 8, the roller needle injector 2 includes a microneedle roller 13, a roller seat 14, and an injector 15. The microneedle roller 13 includes an outer roller 16, and the peripheral wall of the outer roller 16 is provided with a plurality of hollow microneedle groups radially distributed with the central axis of the outer roller 16 as the center, and each hollow microneedle group is composed of the same preset number of hollow microneedles 17, and each hollow microneedle 17 belonging to the same hollow microneedle group is on the same plane. The microneedle roller 13 also includes a spindle member 18, and both ends of the spindle member 18 are fixedly connected to the roller seat 14, and a supporting portion 19 is formed in the middle of the spindle member 18 to cooperate with the inner wall surface of the outer roller 16 and support the outer roller 16. The supporting portion 19 is formed with a preset number of sub-liquid channels 20, and when each of the hollow microneedle groups is rotated to a set position, the internal channels of its hollow microneedle 17 are respectively connected to the corresponding sub-liquid channels 20. For example, when each of the hollow microneedle groups is rotated to Figure 8 When the C setting position is shown, the internal channels of the hollow microneedle 17 are connected to the corresponding sub-liquid channels 20 respectively. At this time, the piston rod of the syringe 15 is pushed, and the PLLA regeneration material in the syringe barrel of the syringe 15 can be injected through the hollow microneedle 17.

[0043] The spindle 18 is also formed with a main liquid channel 21 connected to each sub-liquid channel 20, and the liquid inlet of the main liquid channel 21 can be opened at one end of the spindle 18. A liquid pipeline 22 connected to the main liquid channel 21 is arranged inside the roller seat 14. The roller seat 14 is also formed with a mounting hole adapted to the front end of the syringe 15, the front end of the syringe 15 is sleeved in the mounting hole, and the nipple of the syringe 15 is connected to the liquid pipeline 22. A rubber ring that prevents the syringe from moving can be arranged in the mounting hole, and when the front end of the syringe 15 is sleeved in the mounting hole, the rubber ring is sleeved on the outer peripheral wall of the syringe.

[0044] Return now Figures 2 to 5At least one enclosure 3 is formed with a long strip opening 23 arranged along the longitudinal direction. When each of the enclosures 3 is in an expanded state, after the roller needle syringe 2 extends into the space surrounded by the enclosure 3 and the elastic membrane 4, the microneedle roller 13 can roll along the long strip opening 23 and the hollow microneedle 17 extends out of the outside of the enclosure 3. After the vaginal dilator 1 is inserted into the vagina and adjusted to a suitable distance between the vaginal walls, the locking piece 12 is used to lock the adjusting rod 5, and then the roller needle syringe 2 is inserted into the space surrounded by the enclosure 3 and the elastic membrane 4, and the microneedle roller 13 is dragged from the inside to the outside along the long strip opening 23, or the microneedle roller 13 is pushed from the outside to the inside along the long strip opening 23, and the piston rod of the syringe 15 is pushed. During this process, many fine channels are formed on the inner wall of the vagina by the microneedle roller 13, and PLLA is injected into the inner wall of the vagina at the same time. Then, the vaginal dilator 1 is rotated at a certain angle, and the microneedle roller 13 is dragged from the inside to the outside along the long strip opening 23 again, or the microneedle roller 13 is pushed from the outside to the inside along the long strip opening 23, and the piston rod of the syringe 15 is pushed until a week of PLLA injection is completed on the inner wall of the vagina.

[0045] In this embodiment, only one enclosure plate 3 is formed with a long strip opening 23 arranged in the longitudinal direction.

[0046] Preferably, the width of the elongated opening 23 is slightly greater than the width of the outer drum 16 , and the elongated opening 23 can also restrict the lateral movement of the microneedle roller 13 .

[0047] The device of this embodiment is used for injecting PLLA regenerative material to improve vaginal dryness and aging. It uses a vaginal dilator in conjunction with a roller needle injector to implement microneedle injection. The roller needle injector can form many tiny channels on the inner wall of the vagina to stimulate the regeneration of collagen, and inject PLLA to improve vaginal aging and further improve vaginal dryness.
