Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to an oral suction tube. Background Technology

[0002] A saliva suction tube is a device used in oral treatment. It is used to remove saliva produced in the mouth, making oral treatment easier.

[0003] Common saliva suction tubes consist of a suction head and a flexible tube, connected to a negative pressure device. Saliva is suctioned out by inserting the suction head into the mouth. However, when performing oral treatment on children, their bite force is weak. Because the saliva suction head is cylindrical, children's bite is unstable, which can easily cause the suction head to wobble. In addition, the tip of the suction head can easily come into contact with the inner wall of the mouth, which can block the opening of the suction head and affect the suction of saliva. Utility Model Content

[0004] The purpose of this invention is to provide an oral suction tube to solve the problems mentioned in the background art.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This utility model provides, for example Figure 1-4 The illustrated oral suction tube includes a suction head 1, a suction tube 2, a liquid inlet structure 3, and a one-way structure 4. The suction head 1 is placed in a child's mouth to suction out saliva. The suction tube 2, made of silicone, is located at one end of the suction head 1 and connects the suction head 1 to an external negative pressure device, allowing saliva to drain along the suction tube 2. The liquid inlet structure 3 is located on the suction head 1 and introduces saliva from the mouth into the suction head 1, ensuring stable suction and normal operation. The one-way structure 4 is located inside one end of the suction head 1, forming a one-way flow component within the suction head 1. The one-way structure 4 restricts one end of the suction head 1, preventing residual saliva in the suction tube 2 from flowing back into the suction head 1.

[0035] Specifically, the liquid inlet structure 3 includes a groove 31, a first drainage groove 32, a second drainage groove 33, a receiving groove 34, and a through hole 35. The groove 31 is disposed on the outer wall of the saliva suction head 1, and the grooves 31 are arranged in a ring array at intervals. Multiple grooves 31 are arranged around the saliva suction head 1 and recessed towards the inner wall of the saliva suction head 1. The multiple grooves 31 increase the stability of the contact between the saliva suction head 1 and the cotton ball, making it easier for the saliva suction head 1 to press the cotton ball firmly. The first drainage groove 32 is opened on the end face of the saliva suction head 1, the second drainage groove 33, the receiving groove 34, and the through hole 35. A first drainage channel 32 is arranged in a ring-shaped array at intervals, allowing saliva in the oral cavity to enter the saliva suction head 1. A second drainage channel 33 is arranged in a ring-shaped array at intervals on the outer wall of one end of the saliva suction head 1, forming an L-shape with the first drainage channel 32. The inner cavities of the second drainage channel 33 and the first drainage channel 32 are connected, and the second drainage channel 33 is used for the inflow of saliva. When the first drainage channel 32 on the end face of the saliva suction head 1 comes into contact with the inner wall of the oral cavity, it easily affects the flow of saliva. The flow channel 32 becomes blocked, and saliva enters the saliva suction head 1 through the second drainage channel 33, ensuring stable suction of saliva by the saliva suction head 1. The receiving channel 34 is opened in the middle of the end face of the saliva suction head 1. The receiving channel 34 is located between the first drainage channels 32, and the receiving channel 34 facilitates the entry of saliva into the position of the first drainage channel 32, making it convenient for saliva suction. The through hole 35 is located in the middle of the receiving channel 34, and the first drainage channel 32, the second drainage channel 33 and the through hole 35 are connected to the inner cavity of the saliva suction head 1. Saliva enters the saliva suction head 1 through the through hole 35. By wrapping a cotton ball around the outside of the saliva suction head 1, the cotton ball sinks into the groove 31, increasing the stability of the contact between the saliva suction head 1 and the cotton ball, making it easier for the saliva suction head 1 to press the cotton ball tightly, and improving the stability of the saliva suction head 1's bite. When the first drainage groove 32 on the end face of the saliva suction head 1 comes into contact with the inner wall of the oral cavity, it is easy to cause blockage of the first drainage groove 32. Saliva enters the saliva suction head 1 through the second drainage groove 33, ensuring the stable suction of saliva by the saliva suction head 1.

[0036] Furthermore, the unidirectional structure 4 includes a fixing ring 41, a valve 42, a fixing post 43, and a connecting rod 44. The fixing ring 41 is fixedly connected to the inner wall of one end of the saliva suction head 1, and is used to install the valve 42 and the fixing post 43. One end of the valve 42 is fixedly connected to the inner wall of the fixing ring 41. The valves 42 are arranged in a ring array, and three valves 42 form a trumpet-shaped structure, which is used to conduct unidirectional flow through the inner cavity of one end of the saliva suction head 1 and prevent the backflow of saliva remaining in the saliva suction tube 2. The fixing post 43 is located in the middle of the inner cavity of the fixing ring 41. The outer wall of one end of the fixing post 43 is attached to the other end of the valve 42, and the fixing post 43 is used to limit one end of the valve 42. The valve 42 is fixed to ensure a stable seal of the saliva suction head 1. One end of the connecting rod 44 is fixedly connected to the outer wall of the fixing post 43, and the other end of the connecting rod 44 is fixedly connected to the inner wall of the fixing ring 41. The fixing post 43 is fixed to the fixing ring 41 through the connecting rod 44. The saliva suction head 1 is connected to the negative pressure device through the suction tube 2. When the negative pressure device is running, it draws saliva and causes the valve 42 to deform and expand to one side, so that the saliva in the saliva suction head 1 passes through the valve 42 and enters the suction tube 2. When the negative pressure device stops running, the valve 42 contracts due to its elasticity and fits tightly against the fixing post 43 to seal the inner cavity of the saliva suction head 1.

[0037] Furthermore, multiple anti-slip protrusions 5 are fixedly connected to the outer wall of the saliva suction head 1. The anti-slip protrusions 5 are arranged at equal intervals and are integrally formed with the saliva suction head 1. The anti-slip protrusions 5 increase the friction coefficient of the outer wall of the saliva suction head 1 and improve the stability of the saliva suction head 1's engagement. One end of the saliva suction tube 2 is provided with a connector 6, which is connected to the negative pressure device. The length of the saliva suction head 1 is 2.5cm and the outer diameter of the saliva suction head 1 is 1.2cm. By increasing the length and diameter of the saliva suction head 1, it is easier to engage the saliva suction head 1. The groove 31 is arc-shaped, and the valve 42 is made of elastic material and can deform to a certain extent. The valves 42 are arranged in a trumpet shape.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
