Description

Technical Field

[0001] The utility model relates to the technical field of oral medical instruments, in particular to a combined saliva suction tube. Background Art

[0002] During the oral treatment process, saliva will be secreted in the mouth. In order to avoid the patient getting up frequently, a saliva suction tube is used to suck away the patient's saliva. The saliva suction tube does not only suck away saliva. During the dental surgery, it can also suck away blood, medicine, food residues, and polished tooth debris. Objects such as tooth debris can easily clog the tube, resulting in ineffective saliva suction and even damage to the machine, causing reflux.

[0003] Prior art, such as the Chinese utility model patent with announcement number CN201921735700, discloses "a disposable saliva suction tube with anti-backflow and filtering functions", which is achieved by arranging two filters in the main suction pipe and a branch pipe between the two filters. After the impurities are separated by the filters, the branch pipe stores the impurities, so as not to cause large particles of impurities to damage the machine and cause liquid reflux. However, this structure has a defect, that is, the branch pipe is connected to the main pipe. When the suction force is unstable, the large particles of impurities stored in the branch pipe are easily separated from the branch pipe and enter the main pipe. Moreover, when the machine itself fails and causes reflux, this structure cannot prevent backflow.

[0004] In addition, four-handed operation is often used during dental treatment, requiring the doctor and assistant to work together to complete the operation. When medical staff are busy, the doctor may need to perform the operation alone. In daily use, weak suction can be used to extract most liquids and impurities, and strong suction is rarely used. At the same time, strong suction is most likely to damage the tongue and oral soft tissue during extraction. Utility Model Content

The adjusting rod 22 is provided with two adjusting rings 222, and one side of the two adjusting rings 222 is respectively provided with a first adjusting groove 223 and a second adjusting groove 224. The scales of different colors on the knob 221 are used to distinguish between strong suction and weak suction, and the two adjusting rings 222 adjust the two arc-shaped connecting grooves 231 respectively.

[0030] The No. 1 adjustment slot 223 and the No. 2 adjustment slot 224 are both in a "V"-shaped structure. The end of the No. 1 adjustment slot 223 is a rectangular extension, and its extension length is the same as the projection length of the No. 2 adjustment slot 224. The top of the No. 2 adjustment slot 224 coincides with the projection extension surface of the No. 1 adjustment slot 223. The "V"-shaped adjustment slot can gradually change the airflow passing area when rotating, and then gradually change the suction strength. The rectangular extension at the end of the No. 1 adjustment slot 223 can keep the airflow passing area stable. The top of the No. 2 adjustment slot 224 coincides with the extension surface of the No. 1 adjustment slot 223, so that during the adjustment process, after the airflow velocity in the No. 1 adjustment slot 223 is stable, it can smoothly connect to the control function of the No. 2 adjustment slot 224.

[0043] Example 3

[0044] Working principle: When there is a shortage of manpower and it is difficult to achieve four-hand operation, doctors can use this device to reduce the replacement of tools. The suction force of this device is provided by the main suction tube 1. When extracting saliva from the patient, the patient's tongue is first pressed down by the tongue depressor 26. The protrusion 263 at the bottom of the tongue depressor 26 can reduce the possibility of vomiting reaction of the patient. The drainage groove 264 guides the saliva to the bottom of the hose 25. When cleaning teeth, part of the tooth fragments or food residues produced are sucked away by the saliva suction tube 2, and other impurities that are difficult to be sucked due to their position or quality are taken away by the digging spoon 262;

[0045] During the process of sucking saliva, saliva and impurities enter the spherical reflux tube 24 from the U-shaped tube 241, and the impurities with large mass will settle at the bottom of the spherical reflux tube 24, and the impurities with small mass will be separated from the saliva through the filter screen 232 at the bottom of the regulating straw 23, and then deposited in the reflux tube 24. When the machine is damaged and the liquid refluxes, the doctor can also find it in time. The liquid in the reflux tube 24 is sucked away through the regulating straw 23, and the sucked liquid reaches the top of the regulating straw 23 and then passes through the drainage groove 264 and enters the adapter 21. The liquid in 1 is sucked away by the main suction pipe 1. When the suction force needs to be adjusted, the knob 221 is used to rotate the adjusting rod 22, so that the adjusting rod 22 drives the two adjusting rings 222 to rotate at the same time. By rotating the adjusting ring 222, the positions of the No. 1 adjusting groove 223 and the No. 2 adjusting groove 224 relative to the adjusting suction pipe 23 are changed, thereby changing the fluid passing area, thereby changing the suction force; when the adjusting suction pipe 23 on one side is blocked due to excessive impurities, the liquid can also be extracted by starting the adjusting suction pipe 23 on the other side, thereby increasing the stability of the saliva suction pipe 2.
