Description

Technical Field

[0001] This utility model belongs to the field of oral medical device technology, specifically relating to an oral suction device in dental treatment equipment. Background Technology

[0002] Currently, saliva suction tubes used in oral treatment mainly fall into the following technical forms: One-piece metal saliva suction tubes: These are made of stainless steel tubing bent into shape. Although they can be sterilized at high temperatures, their function is limited and they cannot adapt to complex scenarios such as deep oral surgery requiring lighting or the need for rapid replacement due to bone fragment blockage. Other multi-module saliva suction tubes use threaded connections (refer to the patent publication number CN223489877U), allowing for module replacement by rotating the threads. However, this method has the following drawbacks: replacement is time-consuming, affecting surgical efficiency; and the threads are prone to wear, leading to decreased sealing and an increased risk of saliva backflow.

[0003] The existing technology currently has three technical defects, as follows: 1. Poor functional expandability: Traditional saliva suction tubes only have a single suction function, requiring frequent instrument changes during the procedure (such as for additional use of deep oral lighting or quick replacement and clearing of obstructions after the saliva suction tube becomes blocked), resulting in a chaotic operation flow. 2. Insufficient connection reliability: Threaded connections rely on the precision of mechanical fit. After long-term use, wear and tear can lead to increased clearance and air leakage. In addition, the saliva tube may loosen and fall off. III. Potential risks to infection control: Complex interface structures (such as threaded grooves) are difficult to disinfect thoroughly, resulting in high levels of microbial residue, which is highly detrimental to hospital infection control design. Utility Model Content

[0004] To address the technical problems of existing technologies, such as limited functionality, unreliable threaded connections, and high risk of cross-infection, this utility model provides a modular saliva suction tube based on a magnetic anti-mistake structure. This enables rapid and accurate replacement of the saliva suction tube with zero mis-installation. Through a standardized interface, it is compatible with saliva suction and lighting functions, reducing the risk of cross-infection, simplifying disinfection, and lowering medical costs.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a magnetic saliva suction device, including a handle and a saliva suction tube. The handle is a straight rod structure, with a handle at one end and a magnetic interface at the other end. The saliva suction tube has a saliva suction port at one end and a magnetic connector at the other end. The magnetic connector is inserted into the magnetic interface to connect the handle and the saliva suction tube. The handle and the saliva suction tube are assembled together and are easy to disassemble and assemble.

[0006] The saliva suction tube is curved, and the curvature of the tube is perfectly suited to the comfort of operation, making it easy for the saliva suction tube to enter the oral cavity for operation.

[0007] The magnetic interface contains a first magnetic ring, and the inner wall of the magnetic interface has multiple arc-shaped slots arranged at equal angles. The magnetic connector contains a second magnetic ring that attracts the first magnetic ring, and the outer wall of the magnetic connector has multiple arc-shaped locking strips arranged at equal angles, with the number of arc-shaped locking strips being the same as the number of arc-shaped slots. During installation, the arc-shaped locking strips are inserted into the corresponding arc-shaped slots to achieve positioning and locking. The first and second magnetic rings attract each other and achieve a locking connection between the magnetic interface and the magnetic connector. The magnetic attraction is sufficient to meet the requirements for fixing and sealing the saliva suction tube.

[0008] The bottom of the magnetic interface is equipped with an elastic sealing ring, and the end of the magnetic connector is equipped with an elastic sealing ring. After the magnetic interface and the magnetic connector are connected together, the elastic sealing rings of the magnetic interface and the magnetic connector are squeezed together to form an elastic sealing structure, which can ensure that there is no air leakage between the magnetic connector and the magnetic interface.

[0009] Both the arc-shaped clip and the arc-shaped groove have semi-circular cross-sectional shapes, and the cross-sectional shape of the arc-shaped clip is adapted to the cross-sectional shape of the arc-shaped groove.

[0010] Preferably, the saliva suction port is a pointed nozzle structure with a gradually changing size.

[0011] Preferably, the saliva suction port is provided with a disc-shaped anti-swallowing end, which has multiple suction holes that communicate with the saliva suction tube.

[0012] An LED light source is installed on the saliva suction tube, with the irradiating end of the LED light source facing the saliva suction port.

[0013] Compared with the prior art, the specific beneficial effects of this utility model are reflected in the following aspects: I. Improved operational efficiency: This utility model shortens the disassembly and replacement time by quickly inserting and attaching the handle and the saliva tube, and has a high connection accuracy and good sealing performance.

[0014] II. Enhanced Infection Control: The sealed joints and interfaces have a smooth and simple structure with a clear surface, making them easy to clean and disinfect, thus reducing the risk of cross-infection.

[0015] III. Functional expandability: This utility model supports arbitrary combinations of saliva suction, lighting, and rinsing modules, and can also add new functional modules, thus expanding its scope of application.

[0016] IV. Safety and Adaptability: This utility model adds a disc-shaped anti-swallowing end, which greatly reduces the risk of accidental swallowing of the saliva tube and improves the adaptability of this magnetic suction system. Attached Figure Description

Detailed Implementation Example 1

[0026] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] like Figure 1-6 As shown, a magnetic saliva suction device includes a handle 1 and a suction tube 2. The handle 1 is made of medical-grade 316L stainless steel and has a straight rod structure. One end of the handle 1 is provided with a handle 11, and the other end of the handle 1 is provided with a magnetic interface 12. One end of the suction tube 2 is provided with a saliva suction port 21, and the other end of the suction tube 2 is provided with a magnetic connector 22. The magnetic connector 22 and the magnetic interface 12 form a foolproof structure. The magnetic connector 22 is inserted into the magnetic interface 12 to connect the handle 1 and the suction tube 2. The handle 1 and the suction tube 2 are assembled together and are easy to disassemble and assemble.

[0028] The saliva suction tube 2 is an arc-shaped tube, and the curvature of the arc-shaped tube is perfectly adapted to the comfort of operation, making it easy for the saliva suction tube 2 to enter the oral cavity for operation.

[0029] A first magnetic ring 121 is arranged inside the magnetic interface 12. Multiple arc-shaped slots 122 are arranged at equal angles on the inner wall of the magnetic interface 12. A second magnetic ring 221 that attracts the first magnetic ring 121 is provided inside the magnetic connector 22. Multiple arc-shaped clips 222 are arranged at equal angles on the outer wall of the magnetic connector 22. The number of arc-shaped clips 222 is the same as the number of arc-shaped slots 122. During installation, the arc-shaped clips 222 are inserted into the corresponding arc-shaped slots 122 to achieve positioning and locking. The first magnetic ring 121 and the second magnetic ring 221 have opposite magnetic properties. The first magnetic ring 121 and the second magnetic ring 221 attract each other and achieve a locking connection between the magnetic interface 12 and the magnetic connector 22. The magnetic attraction force is sufficient to meet the fixing and sealing requirements of the saliva suction tube 2.

[0030] The bottom of the magnetic interface 12 is provided with an elastic sealing ring, and the end of the magnetic connector 22 is provided with an elastic sealing ring. After the magnetic interface 12 and the magnetic connector 22 are connected together, the elastic sealing rings of the magnetic interface 12 and the magnetic connector 22 are squeezed together to form an elastic sealing structure, which can ensure that there is no air leakage between the magnetic connector 22 and the magnetic interface 12.

[0031] Both the elastic sealing rings installed on the magnetic interface 12 and the magnetic connector 22 are installed using a snap-fit ​​method. Before each use, the sealing ring is unsealed and placed into the corresponding slot for fixation. After use, the elastic sealing ring is removed and disposed of according to regulations to avoid cross-contamination. Furthermore, the surfaces of the annular slots and the elastic sealing rings are very smooth, facilitating easy installation and removal and ensuring thorough disinfection.

[0032] Both the arc-shaped card strip 222 and the arc-shaped card groove 122 have semi-circular cross-sectional shapes, and the cross-sectional shape of the arc-shaped card strip 222 is adapted to the cross-sectional shape of the arc-shaped card groove 122.

[0033] Preferably, the saliva suction port 21 is a pointed nozzle structure with a gradually changing size.

[0034] During installation, the magnetic connector 22 is inserted into the magnetic interface 12 to achieve quick connection, and the magnetic connector 22 is pulled out of the magnetic interface 12 to achieve quick disassembly. A large axial pulling force is required when pulling out to avoid accidental detachment. The disassembly and assembly time is short and the error connection rate is low. Example 2

[0035] The difference between this embodiment and Embodiment 1 lies in the structure of the saliva tube 2: as follows Figure 7 As shown, an LED light source 24 is arranged on the saliva suction tube 2, with the irradiation end of the LED light source 24 facing the saliva suction port 21. The LED light source 24 is powered by a miniature battery, which is convenient for doctors to operate.

[0036] Among them, the LED light source 24 is built-in, sealed and waterproof, and can be quickly disinfected without contacting patients, thus avoiding the risk of hospital-acquired infections. Example 3

[0037] The difference between this embodiment and Embodiment 1 lies in the structure of the saliva tube 2: as follows Figure 8 As shown, the saliva suction port 21 is equipped with a disc-shaped anti-swallowing end 23. The disc-shaped anti-swallowing end 23 is provided with multiple suction holes that communicate with the saliva suction tube 2. The diameter of the disc-shaped anti-swallowing end 23 is larger than the size of the throat. In special circumstances, the disc-shaped anti-swallowing end 23 can prevent children from swallowing it and ensure safety.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model shall be included within the scope of the present utility model.
