Technical Field
[0001] This utility model relates to the field of pediatric oral diagnosis and treatment technology, specifically a novel saliva suction tube suitable for pediatric oral diagnosis and treatment. Background Technology
[0002] During pediatric oral treatment under a rubber dam, maintaining a clear view of the treatment area requires timely removal of water and debris generated during the procedure, and providing the dentist with ample operating space. Without a rubber dam, the rigid suction tube tip can easily cause damage and bleeding to the oral mucosa and capillaries in children, and can also easily cause throat discomfort leading to vomiting, making the procedure somewhat inconvenient for the dentist, especially when the child's cooperation is limited. Therefore, designing a pediatric-specific soft rubber suction tube that effectively protects soft tissue while expanding the dentist's operating space is particularly important.
[0003] However, existing novel saliva suction tubes suitable for pediatric dental treatment have the following drawbacks:
[0004] (1) Existing new saliva suction tubes suitable for pediatric oral diagnosis and treatment have a weaker function in reducing oral stimulation. Existing saliva suction tubes are generally inserted directly into the child's mouth. The suction tip is relatively hard, and friction in the mouth may cause bleeding and damage to the oral mucosa.
[0005] (2) The existing new saliva suction tubes used in pediatric oral diagnosis and treatment have weak fixation function. When performing saliva suction, the user cannot control the distance of the saliva suction tube well, which may cause nausea and vomiting in children when it is close to the throat. Utility Model Content
[0006] The purpose of this invention is to provide a novel saliva suction tube suitable for pediatric oral diagnosis and treatment, in order to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a novel saliva suction tube suitable for pediatric oral diagnosis and treatment, comprising a protective component and a fixing and limiting component, wherein the protective component is composed of a heat shrink tube, a soft wire, a silicone soft tube and a saliva suction head, wherein a silicone soft tube is provided on the inner wall of the heat shrink tube, a soft wire is installed between the heat shrink tube and the silicone soft tube, and a saliva suction head is provided at the top end of the heat shrink tube;
[0008] The fixed limiting component consists of a fixed ring, an elastic rope, a pressure plate, a locking block, a locking groove, and a limiting block. The fixed ring is installed on the surface of the heat shrink tubing, and a locking groove is opened on the inner wall of the fixed ring. A locking block is installed on one side of the surface of the heat shrink tubing located on the fixed ring, and an elastic rope is installed on the side of the fixed ring.
[0009] Optionally, a slot is provided on one side of the fixing ring, and a locking block is provided on the inner wall of the slot. A tongue depressor is installed on one side of the locking block. The connection between the slot and the locking block can fix the tongue depressor. The size of one end of the locking block is gradually increased to stably lock the tongue depressor.
[0010] Optionally, the card slot and the card block have the same width, and the card slot and the card block fit together. The fitting of the card slot and the card block is used to limit the heat shrink tubing.
[0011] Optionally, there are two card blocks, which are symmetrically distributed. The symmetrical distribution of the card blocks can stably drive the movement of the terminal pipe.
[0012] Optionally, the surface of the saliva suction head is provided with a plurality of saliva suction holes, which are arranged at equal intervals. The equidistant arrangement of the saliva suction holes can effectively clean saliva and debris in the child's mouth. Furthermore, due to the large number of saliva suction holes, saliva can be suctioned from all directions, thereby improving suction efficiency.
[0013] Optionally, there are four soft wires arranged at equal intervals. The equidistant arrangement of the soft wires allows the heat shrink tubing to be bent at multiple angles, enabling it to attract impurities and saliva to different locations in the oral cavity.
[0014] Compared with existing technologies, the beneficial effects of this utility model are:
[0015] This new type of saliva suction tube is suitable for pediatric oral treatment. It consists of heat-shrink tubing, a flexible wire, and a silicone tube. The silicone tube is available in various colors and has an opening diameter of 2mm x 4mm. The outer heat-shrink tubing is a transparent material resistant to temperatures from -55℃ to 125℃, with a diameter sufficient to accommodate the silicone tube. The outer heat-shrink tubing shrinks at suitable temperatures, making it ready for use. The flexible wire is made of a soft, elastic material that can be bent freely to ensure comfort in the oral cavity. The wire has a diameter of 0.9mm and a length of 20-25cm. The suction tip is a soft protective sleeve with a 5mm aperture and a length of approximately 20-25mm. The soft material of the suction tip will not irritate the child's oral mucosa, protecting it. The adjustable flexible wire allows the silicone tube to rotate within a certain angle to suction saliva.
[0016] This new type of saliva suction tube is suitable for use in pediatric oral treatment. It features a fixed ring, elastic cord, tongue depressor, locking block, locking groove, and limiting block. In use, the elastic cord is placed around the child's head, horizontally aligned with the back of the child's head at the level of their lower jaw. The limiting block, which secures the tongue depressor, engages with the fixed ring. The tongue depressor holds the child's tongue in place, preventing interference with saliva suction. The locking block and locking groove allow the heat-shrink tubing to be manually moved within a certain length. The locking groove limits the locking block and the heat-shrink tubing, preventing it from detaching from the fixed ring. Attached Figure Description

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.
[0023] Please see Figures 1-4 As shown, the present invention provides a technical solution: a novel saliva suction tube suitable for pediatric oral diagnosis and treatment, comprising a protective component 1 and a fixing and limiting component 2. The protective component 1 is composed of a heat shrink tube 101, a soft wire 102, a silicone tube 103 and a saliva suction head 104. The inner wall of the heat shrink tube 101 is provided with a silicone tube 103, and a soft wire 102 is installed between the heat shrink tube 101 and the silicone tube 103. The top end of the heat shrink tube 101 is provided with a saliva suction head 104.
[0024] The fixed limiting component 2 consists of a fixed ring 201, an elastic rope 202, a pressure plate 203, a locking block 204, a locking groove 205, and a limiting block 206. The fixed ring 201 is installed on the surface of the heat shrink tubing 101, and the locking groove 205 is opened on the inner wall of the fixed ring 201. The locking block 204 is installed on one side of the surface of the heat shrink tubing 101 located on the fixed ring 201, and the elastic rope 202 is installed on the side of the fixed ring 201. The silicone tubing 103 can be in various colors, and the diameter of the ring opening is 2mm×4mm. The outer heat shrink tubing 101 is a transparent heat shrink tubing that can withstand temperatures from -55℃ to 125℃. Its diameter is sufficient to accommodate the silicone tubing 103. The outer heat shrink tubing 101 shrinks at a suitable temperature, making it ready for use. The soft wire 102 is made of a soft and flexible material that can be bent freely to ensure comfort in the oral cavity. The soft wire 102 has a diameter of 0.9mm and a length between 20-25cm. The saliva suction tip 104 has a 5mm orifice and a length of approximately 20-25mm. The left and right soft protective sleeves and the soft saliva suction head 104 are made of a soft material that will not irritate the child's oral mucosa and are used to protect the oral mucosa. The adjustable soft wire 102 can drive the silicone tube 103 to rotate within a certain angle and draw out saliva. The elastic rope 202 is put around the child's head, with the horizontal position at the back of the child's head at the horizontal line of the child's lower jaw. The limiting block 206 that fixes the tongue depressor 203 is engaged with the fixing ring 201. The tongue depressor 203 can press down on the child's tongue to prevent it from affecting the saliva suction. The engagement of the locking block 204 and the locking groove 205 allows the heat shrink tube 101 to be moved manually within a certain length. The locking groove 205 is used to limit the locking block 204 and limit the heat shrink tube 101 to prevent it from falling off the fixing ring 201.
[0025] A slot is provided on one side of the fixing ring 201, and a locking block 204 is provided on the inner wall of the slot. A tongue depressor 203 is installed on one side of the locking block 204. The connection between the slot and the locking block 204 can fix the tongue depressor 203. The size of one end of the locking block 204 is gradually enlarged to stably lock the tongue depressor 203.
[0026] The card slot 205 and the card block 204 have the same width and fit together. The fit between the card slot 205 and the card block 204 is used to limit the heat shrink tubing 101.
[0027] There are two card blocks 204, which are symmetrically distributed. The symmetrical distribution of card blocks 204 can stably drive the movement of the dormitory pipe.
[0028] The surface of the saliva suction head 104 has several saliva suction holes arranged at equal intervals. The equidistant arrangement of the saliva suction holes can effectively clean saliva and debris in the child's mouth. Furthermore, due to the large number of saliva suction holes, saliva can be suctioned from all directions to improve suction efficiency.
[0029] There are four soft wires 102 arranged at equal intervals. The equal-interval arrangement of the soft wires 102 allows the heat shrink tubing 101 to be bent at multiple angles, enabling it to attract impurities and saliva to different locations in the oral cavity.
[0030] In this invention, the working steps of the device are as follows:
[0031] Step 1: The silicone tube 103 can be in various colors, with a bead diameter of 2mm × 4mm. The outer heat-shrink tubing 101 is a transparent heat-shrink tubing that can withstand temperatures from -55℃ to 125℃. Its diameter is sufficient to accommodate the silicone tube 103. The outer heat-shrink tubing 101 will shrink at the appropriate temperature, and it is ready for use after shrinking. The soft wire 102 is made of a soft and flexible material that can be bent at will to ensure comfort in the oral cavity. The diameter of the soft wire 102 is 0.9mm, and its length is between 20-25cm. The saliva suction head 104 is a soft protective sleeve with a 5mm aperture and a length of about 20-25mm. The saliva suction head 104 is made of a soft material that will not irritate the oral mucosa of children. It is used to protect the oral mucosa. The adjustable nature of the soft wire 102 allows the silicone tube 103 to rotate within a certain angle and draw out saliva.
[0032] The second step: Place the elastic cord 202 around the child's head, with the horizontal position at the back of the child's head, aligned with the horizontal line of the child's lower jaw. Secure the limiting block 206 of the tongue depressor 203 to the fixing ring 201. The tongue depressor 203 can press down on the child's tongue to prevent it from affecting saliva suction. The locking block 204 and the locking groove 205 fit together, allowing the heat shrink tube 101 to be manually pushed within a certain length. The locking groove 205 is used to limit the locking block 204 and the heat shrink tube 101, preventing it from coming off the fixing ring 201.
