ABSTRACT:
The present invention relates generally to protective face masks, and more particularly to face masks primarily for dentistry practice.
EXAMPLES OF THE PRIOR ART
In U.S. Pat. No. 5,303,423 for Face Shield/Mask Combination issued to Gazzara et al. on Apr. 19, 1994, there is provided for use during medical procedures for the protection of medical personnel who, during such procedures, are subject to blood and other bodily fluids coming into contact with their face, a suitable face mask to obviate such contact, it being explained that such contact is dangerous because of the potential presence of the deadly AIDS virus or other harmful pathogens.
Thus, in dentistry practice, a face mask is used to obviate disease transmission between a patient and dentist, and the dentist, the user of the face mask, will dispose of the face mask between dental procedures to obviate disease transmission between patients. To facilitate the use of the face mask, used without exception by the dentist, the elimination of the discomfort of the elastic ear loops is the thrust of U.S. Pat. No. 5,424,787 for Eyeglasses With Mask Support Attachment Means issued to Peter J. Zegarelli, a coinventor of the present invention, on Jun. 13, 1995, and exemplifies the prior art effort concerned with the face mask for the dentist's use.
Underlying the present invention is the recognition that often the dental procedure provided the patient will entail the use of an air abrasion system, one such exemplary system being one using alumna powders of 27 to 50 microns and which gives rise to a fine particulate in surrounding relation about the patient which, without adequate protection provided to the patient, could get into the patient's nose and eyes with possible harmful consequences.
Broadly, it is an object of the present invention to provide a face mask affording protection to the patient, thus addressing a shortcoming of the prior art.
More particularly, it is an object to provide a dental patient's face mask affording effective protection against airborne micron-sized particulate.
The description of the invention which follows, together with the accompanying drawings should not be construed as limiting the invention to the example shown and described, because those skilled in the art to which this invention appertains will be able to devise other forms thereof within the ambit of the appended claims.
