Description

Technical Field

[0001] The utility model relates to the technical field of saliva suction tubes, in particular to a stomatological saliva suction tube with a strong or weak suction force adjustment mechanism. Background Art

[0002] The oral saliva suction tube is a medical device used to help patients eliminate the discomfort caused by water mist and dust during oral treatment, provide doctors with a clear and dry operating area, maintain clean air in the clinic, and prevent potential infection between medical staff and patients. Therefore, the oral saliva suction tube has become a very important auxiliary tool. At the same time, the oral saliva suction tube is also safe, painless, and easy to use. It is widely used in clinical treatment of stomatology. The oral saliva suction tube is usually made of plastic, silicone and other materials. It is mainly used to collect saliva samples from the patient's mouth for disease detection and diagnosis. One end of the saliva suction tube is a long straw, and the other end is a suction head. The suction head is usually spherical or flat, which can better absorb saliva. The material of the saliva suction tube should be non-toxic, odorless, and tasteless to ensure the purity and reliability of the collected saliva sample. The use of the saliva suction tube is very simple. You only need to put the suction head into the patient's mouth and let the patient hold the suction head to absorb saliva. The saliva suction tube is widely used in medical institutions such as hospitals and clinics, as well as laboratories, scientific research institutions and other fields. It is a very important medical device.

[0003] For example, the patent document with application number CN202321027200.7 discloses a saliva suction tube. With the saliva suction tube of the utility model, the tapered tip at the lower end of the tube body can be easily inserted into the alveolar socket to absorb saliva or bleeding therein; the LED lamp bead near the lower end can be bent by bending its two wires to be in a position where it can directly illuminate the surgical area, thereby providing a clear field of vision for the smooth progress of the operation. However, the saliva suction tube cannot adjust the strength of the suction force of the saliva suction tube, and its function is relatively single.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a dental saliva suction tube with a strong and weak suction force adjustment mechanism is proposed. Utility Model Content
