摘要:
The discovery of this invention is that the use of an aseptic barrier in the form of a layer of material which is impervious to the passage of water in combination with at least one layer of absorbent tissue in the form of a disposable tissue or handkerchief can function to reduce materially the transfer of pathogens such as viruses and bacteria from the bodily internal products, mucous and fluid effluent from inside a person to his hand. The above principles may be embodied in a disposable tissue including an aseptic barrier or in a method of entrapping nasal secretions in such a way that contamination of the environment from infected noses be avoided. This is accomplished by the creation of a trap in the form of a mitten-like bag, resistant to the passage of aqueous liquids, with facial tissue affixed to the outside of this mitten-like bag.
