About.

Humans are made up of various tissues, and skin is one of them. Methods of delivering the drugs required to the dermal layer of the skin or below include a method of applying the drug to the skin, a method of injecting the drug by piercing it shallowly through an injection needle, and the like.

The method of applying the drug to the skin increases the delivery time of the drug through the thick and dry epidermal layer, especially the dense basement membrane, and evaporates into the atmosphere as time passes while the drug is applied to the skin. There is a low problem. In addition, when the protein molecular weight is more than a specific molecular weight, such as about 500 Da (Dalton) or more, it is difficult to deliver through the skin.

In addition, as a tool used in the procedure using a needle, there is generally a syringe, and the syringe is composed of a cylinder in which a drug is stored, a needle installed at the end of the cylinder, and a piston installed inside the cylinder. Is pushed out with a piston and injected into the human body through a needle. However, in the method of injecting a drug through a syringe, it is difficult to control the injection dose due to the drug remaining in the passage, pain may accompany the injection site, and strong skin irritation such as skin damage or bleeding may be caused.

In addition, when the user is unable to adjust the injection pressure of the syringe, the injection solution aggregates inside the user's skin, causing the user's skin to swell, resulting in secondary pain.

In addition, the conventional syringe has a problem that causes a lot of pain to the person to be treated because the operator cannot maintain a constant force pressing the piston, and the cylinder is also difficult to stably fix. Due to these problems, there is a problem that it is difficult for a person without specialized skills, such as a medical staff, to use.
