Description

Technical Field

[0001] The utility model relates to the field of saliva suction tubes, in particular to a multifunctional saliva suction tube for dental use. Background Art

[0002] During oral treatment, oral secretions, cooling water introduced by treatment instruments, and the patient's blood can cause varying degrees of moisture interference and contamination in the oral treatment area. It is essential to promptly remove the patient's saliva, cooling water, and blood using a saliva aspirator during surgery to maintain a clear and relatively moisture-free surgical field. The front end of the saliva aspirator is detachably connected to a saliva suction tube.

[0003] An existing saliva suction tube, such as Figure 1 、 Figure 2 As shown, the saliva suction head and the tube body are fixed together as an integrated structure.

The front end of the tube body 1 (the end facing the oral cavity) is fixed with an external threaded connector 11, and three saliva suction heads are detachably provided in conjunction with the external threaded connector 11, namely a small-caliber suction head ( Figure 3 )、Large diameter suction head( Figure 4 ) and root canal suction tips ( Figure 5 ).

[0029] The small-caliber suction head includes a head body 21 with six first saliva suction holes 22 evenly distributed around its circumference. An annular connecting portion 23 is fixed to the upper end of the head body 22. The connecting portion 23 includes an internal thread 231 that mates with the external threaded connector 11 at the front end of the tube body 1. The first saliva suction holes 22 are square in shape, 0.15 cm wide and 0.5 cm long.

[0030] The large-diameter suction head comprises a head body 21. Three secondary saliva suction holes 24 are defined along the circumference of the head body 21. These holes are formed by merging two adjacent primary saliva suction holes 22 (minus the spacer). An annular connector 23 is fixed to the upper end of the head body 21. This connector 23 includes internal threads 231 that mate with the externally threaded connector 11 at the front end of the tube body 1. The secondary saliva suction holes are square in shape, 0.5 cm wide and 0.5 cm long.

[0031] The root canal suction head includes an internal threaded joint 3 that cooperates with the external threaded joint 11 at the front end of the tube body 1. A slender suction tube body 31 with a gradually decreasing diameter is fixed at the lower end of the internal threaded joint 3, and a sheet-shaped handle 32 is also fixed on the outside of the internal threaded joint 3.

[0032] When in use, the small-caliber suction head is used to suck water and saliva from the oral cavity. The advantage of the small diameter is that it can avoid damaging the mucosa, and the head body 21 can be disassembled through threads for easy replacement and maintenance. The large-caliber suction head is used to suck the rinsing fluid after the rubber dam is applied. It can quickly absorb the rinsing fluid to avoid affecting the doctor's operation, and the head body 21 can be disassembled through threads for easy replacement and maintenance. The root canal suction head is used to suck exudate from the root canal or to suck the rinsing fluid before root canal filling and dry the root canal. The suction head can be disassembled through threads for easy replacement and maintenance. Example 2

[0033] like Figure 6 As shown, an annular protrusion 12 is fixedly provided on the outer side of the rear end of the tube body 1.

[0034] During use, the annular protrusion 12 can increase the friction of the pipe body, thereby preventing workers from slipping when holding the pipe body 1 for installation.
