A kind of injection needle with blunt end for cosmetic injection

Abstract

The invention discloses a blunt-end injection needle for beauty injection, which comprises a base, a cylinder is fixedly mounted on the base, a blunt needle body is fixedly mounted on the cylinder, and a mounting sleeve is sleeved on the outside of the base. A mounting hole is provided in the mounting sleeve. In the present invention, the injection end of the syringe is inserted into the inner cavity of the base, and the base is fixed on the syringe through the friction force between the injection end and the surface wall of the inner cavity of the base. Rotation, according to the principle of screw transmission, drives the rotation sleeve to move, extrudes the circular ring to move, the oblique contact block slides in the groove, drives the end of the elastic clamp block to move inward, and drives the clamp block to clamp the injection end of the syringe, which enhances the device's stability. Fixing effect, the thread has a self-locking function, which fixes the whole device on the syringe, and prevents the device from being separated from the syringe to affect the operation during the cosmetic injection process, which is convenient for the use of the device.

Description

technical field [0001] The invention relates to the technical field of beauty, in particular to a blunt-ended injection needle for injection beauty.

Problems solved by technology

[0003] The tools for injecting beauty include blunt needles, hyaluronic acid and syringes. By squeezing the syringes, the hyaluronic acid in the syringes is injected into the skin to achieve cosmetic effects. The blunt needles and syringes in the prior art are connected by inserting the injection end of the syringe into the blunt skin. In the inner cavity of the needle base, the blunt needle is fixed on the syringe through the friction between the injection end and the surface wall of the inner cavity of the blunt needle base. However, this fixing method is not firm enough. It is easy to detach, which will affect the operation, and it is not convenient to use the device
