Description

A retractable saliva suction tube

technical field

The utility model belongs to the technical field of medical devices and relates to a retractable saliva suction tube.

Background technique

In the existing technology, oral and maxillofacial trauma wounds vary in size, depth and irregular shape, so it is impossible to uniformly use a sterile scale to measure the depth and length of the wound, resulting in doctors being unable to determine the depth and length of the wound in the process of writing medical records. Quantification leads to the lack of effectiveness in judging the patient's wound condition in the medical record.

At the same time, the size of the oral and maxillofacial wounds of the patients varies, and the amount of blood loss during the operation also varies. The doctor can choose a suitable saliva suction tube to remove the blood in the operation area to maintain a clear view. And during oral examination and treatment, the patient's mouth will secrete a certain amount of saliva. In the existing technology, an assistant needs to use a traditional saliva suction tube to suck the patient's saliva, so as to assist the doctor to maintain a clear view of the mouth and maintain the patient's comfort. Spend. However, part of the treatment in most dental clinics is performed by a single doctor. In the absence of effective fixing devices for the traditional saliva suction tube, it is easy to slip off the saliva suction tube, which can easily lead to accidental swallowing of small instruments, suffocation and other adverse events. Not only It is not convenient for doctors to operate, and it also reduces the work efficiency of doctors, affects the experience of patients, and is not conducive to improving the safety and quality of medical care.

Therefore, a retractable saliva suction tube is needed to solve the problems in the prior art that the saliva suction tube lacks an effective fixing method, cannot quantify the depth and length of the wound, and cannot assist doctors in evaluating the wound condition.

Utility model content

The utility model provides a retractable saliva suction tube, which intends to solve the problems in the prior art that the saliva suction tube lacks an effective fixing method, cannot quantify the depth and length of the wound, and cannot assist doctors in evaluating the wound condition.
