These drawings are all simplified schematic diagrams, only schematically showing the basic structure of the present utility model, so they only show the components related to the present utility model.

[0028] Embodiment 1

[0029] As Figure 1 、 2 shown, a sterile microneedle applicator for the face or other parts includes a connector 1 and a bracket 2. The front end of the bracket 2 is rotatably connected to a roller 3 through a connecting shaft 8. The side surface of the bracket 2 in contact with the roller 3 is set as an arc surface matching the roller 3, and a plurality of microneedles are evenly distributed on the roller 3.

[0030] The connector 1 and the bracket 2 are connected by threads. Specifically, one end of the bracket 2 connected to the connector 1 is a hollow structure. One end of the connector 1 connected to the bracket 2 is provided with an annular protrusion 11. Threads are provided on the periphery of the annular protrusion 11 and are threadedly connected to the inner wall of the bracket 2. The center of the annular protrusion 11 penetrates to the bottom of the connector 1. After the connector 1 and the bracket 2 are fitted, a chamber for containing the liquid medicine is formed. The bracket 2 is provided with a bump 5 on the side close to the roller 3, and a medicine outlet channel 9 is opened on the bump 5. The medicine outlet channel 9 communicates with the chamber to the bottom of the connector 1, and the connector 1 is connected to a syringe Luer connector to inject the liquid medicine.

[0031] Embodiment 2

[0032] As Figure 3 、 4 shown, a sterile microneedle applicator for the female private part includes a connector 1 and a bracket 2. The front end of the bracket 2 is rotatably connected to a roller 3 through a connecting shaft 8. The side surface of the bracket 2 in contact with the roller 3 is set as an arc surface matching the roller 3, and a plurality of microneedles are evenly distributed on the roller 3.

[0033] The described joint 1 and bracket 2 are connected by threads. Specifically, one end of the bracket 2 connected to the joint 1 is a hollow structure. One end of the joint 1 connected to the bracket 2 is provided with an annular protrusion 11. Threads are provided on the periphery of the annular protrusion 11 and are threadedly connected to the inner wall of the bracket 2. The center of the annular protrusion 11 penetrates to the bottom of the joint 1. After the joint 1 and the bracket 2 are matched, a chamber for accommodating the liquid medicine is formed. The bracket 2 is provided with a convex block 5 on one side close to the roller 3. A medicine outlet channel 9 is opened on the convex block 5. The medicine outlet channel 9 communicates with the chamber to the bottom of the joint 1. The joint 1 is connected to a syringe Luer connector to inject the liquid medicine.

[0034] A protective cover 4 is covered above the described roller 3. The protective cover 4 is detachably connected to the bracket 2.
