Definitions

  • the invention relates to face masks, particularly to medical oral treatment face masks.
  • Oral treatment is a recognized international specialty in dentistry. It includes the diagnosis, surgical and related treatment of diseases, injuries and defects involving both the functional and esthetic aspects of the hard and soft tissues of the head, mouth, teeth, gums, jaws and neck.
  • Oral treatment as a specialty is usually defined as a dental specialty.
  • a patient When a patient is being treated, he or she must open his or her mouth to be checked and operated by a dentist.
  • a liquid suction tube also has to be put in the patient's mouth to drain out saliva, blood and swarf.
  • water injected from a dental water jet or the patient's saliva can easily splash or flow out. This may make the patient feel uncomfortable and may stain the patient's clothing.
  • An object of the invention is to provide a medical oral treatment face mask, which is provided with an opening and a water-absorbent layer to absorb liquid from a patient's mouth. This can avoid a patient feeling uncomfortable or prevent a patient's clothing being stained.
  • the medical oral treatment face mask of the invention includes a mask body and a band set.
  • the mask body includes a water-repellent layer, an isolation layer and a water-absorbent layer.
  • the isolation layer has an opening associated with the water-repellent layer.
  • the water-absorbent layer is arranged between the water-repellent layer and the isolation layer.
  • the band set is fixed on two sides of the mask body.
  • the medical oral treatment face mask of the invention includes a mask body having an opening and a water-absorbent layer arranged around the opening on the mask body.
  • the method for using a medical oral treatment face mask includes the steps of:
  • Liquid splashed from a patient's mouth can be absorbed by the water-absorbent layer. This can prevent the patient from feeling uncomfortable and keep clothing clean.
  • the mask body can prevent medical apparatus, the medical care personnel or other matters from touching the patient's face and can prevent drugs from being accidently absorbed by the patient. This can increase the safety during oral treatment.
  • the water-absorbent layer is extending from the bottom edge to half the area of the mask body approximately. In other words, all the upper half of the mask body is highly breathable. This makes it possible for the patient to smoothly and comfortably breathe with the mask on.
  • the isolation layer can be a breathable filter fabric or a meshed fabric which is not water absorbent, the water-absorbent layer can be isolated with the isolation layer. As a result, the water-absorbent layer can be prevented from direct contact with the patient's face. This can keep the patient dry and clean.
  • the mask of the invention can fit the patient's face.
  • the water-absorbent layer is disposed extending from the bottom edge of the mask body to three-fifths of the total area approximately or it can be formed with an aperture over the opening. Thus, the water-absorbent layer can surround the patient's mouth to enhance water absorption.
  • the mask further includes a filter layer.
  • the filter layer can purify air breathed by the patient to prevent the patient from infection.
  • the mask body is formed with a bag extending and folded from the bottom edge, and the water-absorbent layer is replaceably received in the bag.
  • the water-absorbent layer can be easily replaced.
