  • Patent number: 4167946
    Abstract: A device for protecting both a patient's teeth and medical instruments (such as tubes, probes, etc.) against damage when such instruments are inserted through the mouth. The device comprises a teeth shield member of semi-rigid material with dimensions greater than the instrument introduced and a support member for the instrument at the periphery of the teeth shield member for securing a side-by-side relationship between the instrument and the teeth shield member. The support member can be in the shape of a slit-open tube into which the instrument can be inserted radially after the introduction of the instrument into the patient. The instrument can be fixed by means of a band tied around the instrument and tied or otherwise fixed to the device, which band can also be used to fix the complete unit in the patient by tieing around his neck.
