Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, and in particular to a saliva suction tube. Background Technology
[0002] In dental treatments, patients often need to maintain a wide-open mouth position for extended periods. However, the salivary glands continuously secrete saliva, making swallowing impossible in this position. Furthermore, during dental procedures or diagnoses, the patient's mouth is stimulated by instruments, leading to increased saliva production. To prevent damage from the high temperatures generated by instruments, dentists periodically spray water into the mouth to cool the teeth. A saliva suction tube is used to promptly remove saliva and water, maintaining a clear view of the patient's mouth. Therefore, a saliva suction tube is necessary to remove the secreted saliva from the mouth.
[0003] For example, utility model CN212816611U discloses a saliva suction tube, which relates to the field of saliva suction tube technology. It includes a tube body, one end of which is fitted with a suction head. The suction head has suction holes running through it. A tongue depressor is fitted onto the outer surface of the tube body, and a shaping wire is provided on one side of the inner surface of the tongue depressor. An adjusting tube is connected to the other end of the tube body, and a fixing hook is connected to the bottom of the adjusting tube. A fixing groove is provided on one side of the fixing hook, and a rubber pad is provided inside the fixing groove. With this saliva suction tube, the tube body is first placed into the patient's mouth using the tongue depressor, fixing groove, fixing hook, and rubber pad. The tongue depressor holds the patient's tongue in place, reducing tongue movement and preventing it from affecting the treatment. The fixing hook is engaged with the corner of the patient's mouth, which is placed in the fixing groove. The rubber pad reduces friction between the fixing groove and the corner of the patient's mouth, protecting it. When the saliva suction device operates, the suction head absorbs saliva from the patient's mouth through multiple suction holes, reducing damage to the oral mucosa.
[0004] However, the existing saliva suction tubes described above draw liquid from the oral cavity through the suction hole at the front end. This requires moving the tube to adjust the position of the suction hole and to suction saliva from multiple locations in the oral cavity. When there are multiple tools in the oral cavity, moving the tube is inconvenient and will interfere with the operation of other tools by medical staff. Utility Model Content
[0005] The purpose of this utility model is to overcome the defects of the existing technology.
[0006] The objective of this utility model can be achieved through the following technical solutions:

[0032] Example 1
[0033] like Figure 1 As shown, this embodiment provides a saliva suction tube, including a tube body 1. The tube body 1 includes a fixed DC section 11, a saliva suction front end 12, and a bent and folded section. The two ends of the bent and folded section are respectively connected to the fixed DC section 11 and the saliva suction front end 12.
[0034] The saliva suction tip 12 has a conical structure, and multiple suction holes 13 are provided on the conical surface of the saliva suction tip 12. The suction holes 13 are evenly distributed on the saliva suction tip 12. A filter screen is provided in the curved and folded section, and a tongue protector 2 is provided on the fixed DC section 11. The tongue protector 2 can be detachably installed on the fixed DC section 11.
[0035] Working principle: Based on the shape of the child's mouth and the position of saliva suction, the bending and folding section is adjusted to change the angle between the saliva suction front end 12 and the fixed direct current section 11, thereby adjusting the orientation and position of the suction hole 13 in the mouth. The evenly distributed suction holes 13 can adapt to multiple positions and angles of saliva suction, and the tongue protector 2 on the fixed direct current section 11 can help fix the tongue, making it easy to place and adjust the saliva suction front end 12.
[0036] The saliva-suction tip 12 is connected to the fixed DC section 11 by a bending and folding section. The bending and folding section can be bent in a specific direction, thereby adjusting the orientation and position of the saliva-suction tip 12 and the suction hole 13. The suction hole 13 can be adjusted without moving the fixed DC section 11, which is convenient and will not interfere with other tools. The suction holes evenly distributed on the conical surface of the saliva-suction tip 12 make the operation of the saliva-suction tip 12 more flexible. Together with the tongue protector 2, the tongue is protected, further improving the safety of adjusting the saliva-suction tip 12.
[0037] Preferred implementation methods, such as Figure 2 As shown, the bending and folding section includes a first bending section 14, a connecting section 15, and a second bending section 16 connected in sequence; the end of the first bending section 14 away from the connecting section 15 is connected to the fixed DC section 11, and the end of the second bending section 16 away from the connecting section 15 is connected to the saliva suction front end 12.
[0038] The curved and folded section adopts a structure in which the first curved section 14 and the second curved section 16 are spliced together. The first curved section 14 can be set at the halfway point of the tube body 1, and the second curved section 16 can be set at the one-third bend of the tube body 1. By using the first curved section 14 in conjunction with the second curved section 16, the adjustment angle range of the suction tip 12 and the bending shape of the tube body 1 can be expanded to accommodate the specific position of the oral cavity for suction, thereby improving the flexibility and practicality of the tube body 1.
[0039] Furthermore, a first filter screen 31 is provided within the first bending section 14. A second filter screen 32 is provided within the second bending section 16. The filter pore size of the second filter screen 32 is larger than that of the first filter screen 31.
[0040] The second filter 32 and the first filter 31 are installed inside the curved and folded section of the tube. The second filter 32, which is closer to the suction tip 12, has a larger pore size and can filter larger impurities in the oral cavity. Then, the first filter 31, which has a smaller pore size, is used to filter smaller impurities, so as to avoid impurities affecting the use of the negative suction device.
[0041] Specifically, the suction holes 13 are evenly distributed along the circumference of the conical surface of the suction tip 12.
[0042] The conical surface design of the saliva suction tip 12 allows for more targeted suction of specific areas within the oral cavity. The evenly distributed suction holes 13 around the conical surface absorb saliva from multiple directions, reducing damage to the oral cavity. Furthermore, the suction holes 13 can adapt to the deformation of the curved and folded sections, ensuring that the suction holes 13 effectively absorb saliva.
[0043] In a preferred embodiment, the tongue protector 2 includes a U-shaped tongue depressor 21 and a U-shaped buckle 22. The bottom end of the U-shaped buckle 22 is fixed to the bottom end of the U-shaped tongue depressor 21, and the buckle 22 is snapped onto the fixed DC section 11.
[0044] Furthermore, an elastic pad is fixed inside the U-shaped pressure tongue 21, and the buckle 22 can be slidably installed on the fixed DC section 11.
[0045] The tongue protector is installed on the fixed DC section via a U-shaped buckle, allowing the U-shaped buckle to rotate circumferentially along the fixed DC section to adjust the orientation of the U-shaped tongue depressor. The U-shaped buckle can also move axially along the fixed DC section to adjust the distance between the U-shaped tongue depressor and the saliva suction tip, adapting to different oral cavity sizes. The structure is simple and easy to adjust, further improving the flexibility and applicability of the saliva suction tube.
[0046] Specifically, the end of the fixed DC section 11 furthest from the bent and folded section is connected to a negative suction device. The fixed DC section 11 is made of rubber hose.
[0047] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
