DEVICE FOR APPLYING A CONTACT ANAESTHETIC

摘要

Device for applying a contact anaesthetic, such as those used mainly in superficial ophthalmological surgery for application of a local anaesthetic, characterized in that it consists of a porous strip of gelatine sponge which is flexible and preferably rectangular in shape with a small thickness, which is impregnated with a topical anaesthetic and is deposited on the surface to be treated, leaving it to act for a short period of time so that anaesthetic is released onto said zone, being discharged at the rear. The invention described offers the main advantage of achieving an intense anaesthetic effect only in the desired zone, leaving completely unaffected the sensitivity outside of the zone covered by the strip, ensuring total co-operation on the part of the patient and avoiding the injections and drawbacks associated with other anaesthetic devices, all this being achieved by means of a low-cost device which is simple to use.
