Description

Oral saliva suction tube

Technical Field

The utility model relates to a saliva suction tube for oral cavity.

Background

In the oral cavity of today, the saliva suction tube is a disposable consumable which is a necessity for daily oral operation and can be inserted into a dental saliva suction device for use. The saliva pipe is inhaled to little suction is more commonly used in the oral cavity field, be convenient for arrange in the molar back region and absorb patient's intraoral saliva, the flush fluid, the water that the cell-phone head spouts etc. but extract the tooth and draw the root, little suction is inhaled saliva pipe suction and is too weak or inhale the saliva pipe head too thick when washing root canal treatment's operations such as root canal, can't absorb the inside root canal internal flushing fluid of tooth pulp chamber, if oral maxillofacial surgery inhales the saliva in addition, often need big suction to inhale the saliva or get into the lacuna in and absorb the sparge water or ooze blood. Saliva suction in oral and maxillofacial surgery is mainly a large-suction saliva suction device or a metal saliva suction pipe with thin pipes replaced, and a lot of inconvenience is caused by switching the saliva suction pipes back and forth. And especially, the small-head large-suction saliva suction tube used outside the mouth can easily damage the oral mucosa and even block the saliva suction tube, and the conventional saliva suction cannot be finished. If two large suction force and small suction force are used for sucking the saliva tube, the switching is troublesome, manpower and material resources are wasted, and the problems that the saliva tube falls off and the like easily occur in the operation process.

In conclusion, the prior ordinary saliva suction pipe only has a small suction saliva suction pipe and a large suction saliva suction pipe for oral and maxillofacial surgery saliva suction, but does not have a large and small saliva suction pipe, and particularly only uses the small suction saliva suction pipe, so that the operations of sucking flushing fluid, extracting teeth, cutting roots and the like are wasted and inconvenient.
