Description

Technical Field

[0001] The utility model relates to the technical field of medical cosmetic appliances, in particular to a supporting device for filling and heightening a nasal columella with PMMA mixed with collagen. Background Art

[0002] Filling and heightening the columella is a safe and effective cosmetic method that can provide immediate support and shaping for the columella. For example, 20% PMMA microspheres can be mixed with 80% bovine collagen solution and injected. PMMA microspheres are not absorbed by the body and can exist for a long time at the injection site, providing a lasting filling effect that can last longer than other absorbable filling materials (up to 10 years or more). While bovine collagen is gradually absorbed by the body after injection, PMMA microspheres stimulate the regeneration of the body's own collagen, making the filling effect look more natural, with soft tissue and no hardening. The effect of heightening the columella can be seen immediately after injection, and the effect is natural.

[0003] Since the regenerative material of PMMA mixed with collagen has insufficient support before shaping, after injection, a hard silicone ring material is generally used and placed in the nostril to support and prevent the newly injected regenerative material from being squeezed and displaced. However, the shapes of nostrils vary, including longitudinal oval, oblique oval, elliptical, rectangular, etc. For longitudinal oval and oblique oval nostrils, the use of a hard silicone ring cannot effectively support the injected regenerative material.

[0021] The following describes a support device for filling and heightening the columella with PMMA mixed with collagen according to an embodiment of the utility model with reference to the accompanying drawings.

[0022] See also Figure 1According to the embodiment of the utility model, the supporting device for filling and heightening the columella with PMMA mixed collagen comprises a maintainer 1 and an elastic capsule 2. The maintainer 1 is used to support the columella after the columella is injected with the regenerative material of PMMA mixed collagen to fill and heighten the columella, so as to avoid the squeezing and displacement of the regenerative material just injected. By squeezing the elastic capsule 2, part of the liquid in its liquid storage space can be transferred to the maintainer 1. After receiving the liquid transferred by the elastic capsule 2, the maintainer 1 can be deformed to clamp and support the columella, thereby avoiding the squeezing and displacement of the regenerative material just injected. After releasing the elastic capsule 2, under the action of the restoring force of the elastic capsule 2 and the restoring force of the maintainer 1, the corresponding volume of liquid flows back into the elastic capsule 2, so that the deformation of the maintainer 1 can be adjusted multiple times, and the maintainer 1 can be easily separated from the columella.

[0023] Specifically, see Figures 2 to 3 The retainer 1 includes a rigid outer profile 3, an elastic inner membrane 4, an elastic top membrane 5, and an elastic bottom membrane 6. The rigid outer profile 3, the elastic inner membrane 4, the elastic top membrane 5, and the elastic bottom membrane 6 together enclose a closed space, which is completely filled with liquid. The rigid outer profile 3 can be a hard PVC shell, and the elastic inner membrane 4, the elastic top membrane 5, and the elastic bottom membrane 6 can all be silicone membranes. After the retainer 1 receives the liquid transferred by the elastic capsule 2, the rigid outer profile 3 only undergoes a slight deformation to maintain the basic shape of the retainer 1, while the elastic inner membrane 4 will undergo a large deformation in the direction away from the rigid outer profile 3, and the elastic top membrane 5 and the elastic bottom membrane 6 will undergo a large deformation outward.

[0024] The elastic inner membrane 4 forms a groove 7 that can be placed on the columella and matches the shape of the columella. The width of the groove is narrowed at the waist 8. Figure 1 After the retainer 1 is put on the columella, the elastic capsule 2 is squeezed to transfer part of the liquid in the liquid storage space of the elastic capsule 2 to the closed space of the retainer 1. During the liquid transfer process, the elastic inner membrane 4 will deform in a direction away from the rigid outer contour 3 to clamp the columella. Figure 4 As shown ( Figure 4 The dashed line is Figure 1 In the state, the elastic inner membrane 4 is deformed, the elastic top membrane 5 and the elastic bottom membrane 6 are deformed outward to increase the height of the maintainer 1 to support the columella. The clamping and supporting effect of the maintainer 1 can effectively prevent the regenerative material just injected into the columella from being squeezed and displaced.

[0025] The liquid storage space of the elastic capsule 2 is completely filled with liquid, and the liquid storage space of the elastic capsule 2 is connected to the closed space of the maintainer 1 through a liquid pipeline 9. Of course, the space in the liquid pipeline 9 is also completely filled with liquid, and the liquid pipeline 9 is provided with a valve 10. The volume change of the liquid under pressure is small, and the deformation of the maintainer 1 can be adjusted by adjusting the amount of liquid in the liquid storage space of the elastic capsule 2 entering the closed space, that is, adjusting the deformation of the elastic inner membrane 4, the elastic top membrane 5, and the elastic bottom membrane 6, thereby improving the applicability of the support device for PMMA mixed collagen filling and heightening the columella.

[0026] After the liquid in the liquid storage space of the elastic sac 2 enters the closed space, the hydraulic pressure at various locations in the closed space is the same. Therefore, the elastic inner membrane 4, the elastic top membrane 5, and the elastic bottom membrane 6 can also undergo adaptability deformation according to the specific shape of the columella, further improving the applicability of the support device for PMMA mixed collagen filling and heightening the columella.

[0027] In this embodiment, the cross section of the elastic inner membrane 4 is curved. The opening of the groove 7 surrounded by the elastic inner membrane 4 can be configured to gradually expand outwards, so as to facilitate the retainer 1 to be placed on the columella.

[0028] In this embodiment, the rigid outer profile 3 is provided with a liquid hole at a position directly opposite to the bottom of the groove 7 , and the liquid pipeline 9 is connected to the closed space of the maintainer 1 through the liquid hole.

[0029] In one embodiment, Figure 5 As shown, the elastic inner membrane 4 corresponding to the waist 8 of the groove 7 and the bottom has the same distance from the rigid outer profile 3 at all locations.

[0030] The supporting device for PMMA mixed collagen filling and heightening the columella of the utility model is suitable for nostrils of various shapes. The supporting device for PMMA mixed collagen filling and heightening the columella of the utility model can effectively prevent the regeneration material just injected into the columella from being squeezed and displaced.
