Description

[0001] SYRINGE KIT FOR TREATING KELOIDS [0002]

The present invention relates to an injection kit for treating keloids, and more particularly, to an injection kit for injecting a therapeutic drug into a keloid protruding to the skin, Lt; RTI ID = 0.0 > keloid < / RTI >

Generally, as the wound heals over time, the collagen fibers are rearranged on the first reddened spine and the proteoglycan is reduced and the blood vessels are pressed and the scars become thinner.

The keloid can not go through the wound healing process as described above, and the wound is constantly reddish and rising, and the scar is hardened and hardened, and it spreads to surrounding normal tissue and grows larger than the original wound.

These keloids are known to occur due to the failure to properly control and inhibit the wound healing process. People with genetic predisposition (approximately 15% of the total population) are predominantly black or dark skinned, After the damage has occurred.

In addition to causing cosmetic problems, keloid skin has a wider range of involvement that can interfere with the movement of joints if they occur in important areas such as the face or joints.

Keloid (or keloid scar) is clinically manifested as skin color, low pigmentation, or hard nodule of erythema. Unlike hypertrophic scars, they can penetrate into the surrounding normal skin beyond the original wound area.

Histopathological diagnosis of keloid (or keloid scar) is as follows. The epidermis is normal, the dermis is proliferated, thick and vascular rich, and infiltration of inflammatory cells is increased compared with normal scar tissue. The collagen bundles of normal dermis are relaxed and disorganized, whereas the keloid dermis is thick and rich in collagen bundles. The most characteristic histological finding of keloids is large, closely spaced collagen fibers composed of numerous fibrils. A thick, hyalinized collagen that is irregularly arranged in a spiral shape is called keloid collagen.

Because these keloids are proliferating in the event of a wound, they are usually treated with injections that take the drug rather than surgical removal.

Typically, hospitals usually use 1cc, 13mm, 26G common syringes for keloid treatment. However, since such a general syringe injects only with the force of the thumb, it is not administered well because the pressure area is very small and the keloid tissue is hard.

If the syringe is larger in diameter and larger, the force of the thumb becomes larger, which makes it difficult to inject and the injection volume is difficult to control, which is not suitable for keloid injection. In addition, if the diameter of the syringe is smaller than 26G, the injection pressure can not be maintained and the needle can be broken.

On the other hand, since keloids are of various sizes, when injecting drugs, the drug should not penetrate normal tissues around the keloid.
