Needle disc roller apparatus

Abstract

A coaxial rotating needle disc roller apparatus is disclosed. The coaxial rotating needle disc roller apparatus comprises: a connecting cap (12); a roller guiding holder (14) coupled to a front end ofthe connecting cap (12); and a needle disc roller (20) maintained to be frontward and rearward moveable to the roller guiding holder (14). The needle disc roller (20) comprises: a roller bracket (22)installed to be linearly frontward and rearward moveable along a guide groove (142) formed in the roller guiding holder (14); a core rotation shaft (21) installed to be rotatable with respect to theroller bracket (22); a roller bobbin (24) installed to be rotatable with respect to the core rotation shaft (21); and a plurality of ring-shaped needle discs (26) and a plurality of ring-shaped spacers (28) both pluralities being restrained to the roller bobbin (24)and rotating, together with the roller bobbin (24), with respect to the core rotation shaft (21).

Description

technical field [0001] The present invention relates to a microneedle roller device that uses a microneedle roller to form tiny pinholes on the skin, and injects medicine through these pinholes. In this state, the microneedle roller is rotated. In the state where the needle pieces in the microneedle roller are constrained by each other, it is composed of a double rotation of the central rotation axis and the mesopore rotation axis that are coaxial with each other, so that more effective A coaxial double-rotating microneedle roller device for microneedling. Background technique [0002] Previously, a microneedle roller device was proposed in which a roller head was combined on the upper end of a medicine container filled with medicine, and a hole through which the medicine could flow out was formed between the medicine container and the roller head. In these conventional devices, the opening is formed by an elastically deformable cutout, and when the drug container is turned...

AI Technical Summary

Problems solved by technology

However, this device uses a delivery method in which the drug falls on the far needle sheet, and it is difficult to deliver reliable drug to each needle, and it is not only difficult to control the deformation of the incision part due to the weight of the ball, but also with the use period increase, the incision part is permanently deformed, and can become unusable

In addition, the existing technology has inconvenience in the process of combining the microneedle roller with the drug container

In addition, the assembly of the prior art assembly including the microneedle roller requires bolt locking or sticking, etc., so it has the disadvantage of poor assembly

[0003] In particular, the existing technology adopts the method of rotating the entire microneedle roller for one axis, so when the microneedle roller is rotated on the skin, the smoothness of rotation is reduced, and further, when the rotation is not very good, due to the microneedle roller There is a concern that the skin may be damaged by the needle sheet by pressing the external force that rotates on the skin
