A DEVICE FOR COLLECTING SALIVA FROM A PATIENT
Document Type and Number:
WIPO Patent Application WO/1994/007419
Kind Code:
A1
Abstract:
A device for collecting saliva from the parotid glands of the mouth. In order to eliminate the need of subpressure or other auxiliaries to anchor known devices for the intended purpose, the inventive device includes a generally bulbous body (2) which has a greater extension in its longitudinal direction than in its transverse direction. The bulbous body is provided with a collecting chamber (4) which has an inlet opening (6) located on the upper side of the body. The largest cross section of the bulbous body is in a plane which passes through the opening (6), and the body includes three external surface regions (7, 8, 9). When seen from above, two (7, 9) of these surface regions are convexly curved while the third region (8) is concavely curved. The surface regions are intended respectively for coaction with the teeth (19) of the upper and the lower jaw, or the upper and the lower jawbone (20), masseter muscle and orbicular muscle of the mouth, in a manner to fixate and hold the device inserted in a patient's mouth in a correct position in relation to the gland.
