  • Endoscopic pillow covering with high absorbency characteristics
    Patent number: 4553538
    Abstract: The present invention is used during an upper gastrointestinal endoscopic procedure with the patient in the left lateral decubitus position. A disposable or nondisposable pillow case or covering extension section is positioned below the patient's mouth. The covering and extension section absorbs any salivary or gastric secretions. In addition, loops or pockets are positioned on the covering or extended area to hold a suction catheter during the endoscopic examination. A suction catheter may be held by attachment to a loop or pocket on the extension section of the pillow covering or may be held on the extension section, near the patient, when the catheter is not in use. The absorbent extended area of the pillow covering employs a plastic layer to further protect the surface below the extended covering area.
