Transdermal-absorption local-anesthesia painless injection puncture alcohol pad

Abstract

The invention provides a transdermal-absorption local-anesthesia painless injection puncture alcohol pad and belongs to the technical field of medical local anesthesia and medical instruments. The alcohol pad is a low-value supply and used for local surface anesthesia of the skin mucosa. Patients, especially children are afraid of injection and puncture and poor in obedience; grease, cream, gel and other dosage forms which are sold in the market and used for local anesthesia are large in dosage, long in onset time and inconvenient to operate and have certain clinical safe risks; in order to overcome the preceding defects, the transdermal-absorption local-anesthesia painless injection puncture alcohol pad is developed. The alcohol pad is a non-woven cloth pad immersed with a solution in a saturated mode, wherein the solution comprises surface anesthetic, a transdermal-absorption agent, a skin light-pervious reinforcing agent and a solvent, and the preceding content are proportioned quantitatively to form the solution. The transdermal-absorption local-anesthesia painless injection puncture alcohol pad is mainly used for injection and puncture portions in medical care, face care and health care, by means of surface anesthesia of the local skin mucosa, the painless effect is achieved, and the transdermal-absorption local-anesthesia painless injection puncture alcohol pad has the advantages of being little in dosage, high in onset speed, free of medical risks and convenient to use, facilitating injection and puncture due to the fact that shallow veins are exposed and clear and the like.
