Description

Technical Field

[0001] The invention relates to the technical field related to medical mechanical equipment, and in particular to an open tongue depressor tool used for oral care operations for infants. Background Art

[0002] Early childhood is the golden and critical stage for the healthy development of oral health. The normal development of the oral cavity is not only related to the eruption and arrangement of teeth, but also has a profound impact on the growth of maxillofacial bones and the overall oral function. During this period, a series of oral care operations are essential. For example, daily routine brushing can effectively remove food debris and dental plaque in the mouth and prevent the occurrence of caries. Regular oral examinations can timely detect potential oral problems and achieve early detection and early intervention. Treatments for oral diseases, such as caries fillings and gingivitis treatment, play a key role in maintaining oral health. However, due to their unique physiological structure, young children have a narrow oral cavity, sensitive swallowing reflex, and a natural fear of unfamiliar operations. When faced with these oral care operations, their cooperation is often very low, and they often show behaviors such as crying, resistance, and struggling. Therefore, there is a special need for an open tongue depressor tool for oral care operations for young children.

[0003] However, the size and shape of the existing open tongue depressor for oral care of infants are fixed, and they cannot adapt to the size differences of the oral cavity of infants of different age groups. If the tool is too large, it is very easy to touch the inner wall of the infant's oral cavity during use, causing unnecessary abrasions or contusions, causing pain to the infant. If the tool is too small, it cannot fully open the oral cavity, resulting in limited vision for care operations, making it difficult to achieve comprehensive and effective cleaning and care of the interior of the oral cavity. At the same time, no combined lighting device is designed, and the lighting function cannot be provided at the same time, resulting in the inability to observe the interior of the oral cavity more clearly, which may lead to insufficient filling of the filling material or position deviation, affecting the treatment effect, and may even cause additional damage to the infant's oral tissue due to improper operation. At the same time, no music playing function is designed. Infants are at a stage of being highly sensitive to unfamiliar things, and it is impossible to attract the attention of the children before the operation, which greatly increases the difficulty of subsequent operations. At the same time, the existing tongue depressor has a single function and cannot fix the open tongue depressor to the infant's oral cavity. During oral care operations, infants are very likely to shake their heads and move their oral cavity due to their young age and weak self-control ability, making it difficult to maintain the stable position of the tool in the oral cavity, which seriously affects the accuracy and efficiency of diagnosis. Summary of the invention

[0004] The purpose of the present invention is to provide an open tongue depressor for oral care of infants, so as to solve the problem that the existing open tongue depressor for oral care of infants proposed in the above background technology has fixed size and shape, and cannot adapt to the size difference of the oral cavity of infants of different age groups. If the size of the tool is too large, it is very easy to touch the inner wall of the infant's oral cavity during use, causing unnecessary abrasions or bruises, causing pain to the infant. If the size is too small, the oral cavity cannot be fully opened, resulting in a limited field of view for care operations, making it difficult to achieve comprehensive and effective cleaning and care of the inside of the oral cavity. At the same time, no combined lighting device is designed, and the lighting function cannot be provided at the same time, resulting in an inability to observe the oral cavity more clearly. The internal situation of the cavity may lead to insufficient filling or position deviation of the filling material, affecting the treatment effect, and may even cause additional damage to the oral tissue of the child due to improper operation. At the same time, the music playback function is not designed. The child is at a stage where the child is highly sensitive to unfamiliar things, and it is impossible to attract the child's attention before the operation, which greatly increases the difficulty of subsequent operations. At the same time, the existing tongue depressor device has a single function and cannot fix the open tongue depressor tool to the child's mouth. During oral care operations, children are prone to head shaking, oral movement, etc. due to their young age and weak self-control ability.

The inner side of the oral care seat 1 is fixedly installed with the fixed roller 1007. The outer side of the fixed roller 1007 is rotatably installed with the clamping plate 1008. The outer side of the clamping plate 1008 is provided with the anti-slip texture 1009. There are two identical sets of the sliding seat 1002, the clamping groove 1003, the connecting column 1004, the lighting lamp 1005 and the control switch 1006, and the sliding seat 1002, the clamping groove 1003, the connecting column 1004, the lighting lamp 1005 and the control switch 1006 are symmetrically distributed about the vertical center line of the slide rail 1001. By providing the lighting assembly 10, the lighting assembly 10 is adjustable. The sliding seat 1002 on the slide rail 1001 drives the lighting lamp 1005 to move. Medical staff can adjust the lighting position and angle according to needs to illuminate every corner inside the oral cavity, avoiding misdiagnosis or operation errors caused by insufficient light. For example, when examining dental caries and oral mucosal lesions, it can be clearly observed, improving the diagnostic accuracy and providing a reliable basis for subsequent treatment.

[0035] The vertical section of the clamping plate 1008 is in an "L" shape. The end of the clamping plate 1008 far from the fixed roller 1007 is adapted to the clamping groove 1003. By providing the clamping plate 1008, the connection between the clamping plate 1008 and the clamping groove 1003 is made more stable, and at the same time, the lighting lamp 1005 is fixed. The lighting lamp 1005 uses high-brightness and low-power LED lamp beads, which can provide sufficient and soft light to illuminate every corner inside the oral cavity.

[0036] The widths of the hook-and-loop fastener 11 and the loop-and-loop fastener 12 are the same. The hook-and-loop fastener 11 and the loop-and-loop fastener 12 are a mother-and-son button structure. By providing the hook-and-loop fastener 11 and the loop-and-loop fastener 12 and using a soft magic tape material, it can be fixed around the head of a child to ensure the stability of the mouth opener during use and is convenient for adjustment according to the head size of the child.

[0037] Working principle: Before using the oral opening tongue depressor tool, the caregiver needs to conduct a comprehensive inspection on it. Carefully check whether the oral care seat 1 is damaged or deformed, and whether the connections of each component are stable. Check whether there are foreign objects blocking parts such as the threaded hole 2, the placement groove 3, the USB interface 4, the music playback port 6, and the sliding groove 7 to ensure that all functions are normal. At this time, the caregiver places the tool on a stable operating table. According to the age of the child and the actual size of the oral cavity, after the caregiver wraps the fixing belt around the child's head, by adjusting the fitting position of the hook and loop fastener 11 and the loop and loop fastener 12, the length of the fixing belt can be flexibly adjusted according to the size of the child's head. The fixing belt fits the child's head, providing a stable fixing force to ensure that the mouth opener will not shift due to the struggle or shaking of the child during use, maintaining the continuity and stability of the oral care operation. Then, the caregiver starts to prepare to adjust the opening and closing component 8. Pick up the hook and loop fastener 11 and the loop and loop fastener 12, estimate the size of the child's head, and initially adjust the fixing belt to an appropriate length range to ensure smooth operation when subsequently wrapping and fixing the child's head. The caregiver holds the rotating arm 801 and slowly rotates it. The rotating arm 801 drives the externally fixedly installed double-threaded lead screw 802 with opposite threads to rotate synchronously. Due to the thread design of the double-threaded lead screw 802 with opposite threads, the moving seat 803 threadedly connected to it will move along the axial direction. The moving seat 803 drives the externally fixedly installed spreading plate 804 to move to both sides or the middle until the distance between the spreading plates 804 is adapted to the size of the child's oral cavity. During this process, the connecting seat 805 slides on the guide rod 806 to ensure smooth movement of the spreading plate 804. At the same time, the directional pulley 809 on the outer side of the mounting base plate 808 slides smoothly in the sliding groove 7, further ensuring the stability of the spreading action and avoiding shaking or deviation. At this time, after the caregiver adjusts the spreading plate 804 in place, if it is necessary to adjust the angle of the tongue depressor 909, the caregiver can operate the extension plate 906. Since the extension plate 906 is connected to the rotating part 903 through the mounting frame 905, and the rotating part 903 can rotate stably in the rotating groove 902 at the bottom of the fixed seat 901. At the same time, the mounting frame 905 is flexibly rotatably connected to the rotating part 903 and the extension plate 906 through connecting components such as the through hole 904, the through hole 907, and the pin shaft. The caregiver can adjust the tongue depressor 909 to the best angle according to the actual oral care operation requirements to accurately press the child's tongue. The caregiver holds the oral opening tongue depressor tool and places it at a suitable position in the child's oral cavity, making the spreading plate 804 fit the inner wall of the oral cavity. Then, wrap the hook and loop fastener 11 and the loop and loop fastener 12 around the child's head, adjust to an appropriate tightness and then stick them firmly to ensure that the tool is stable during use and will not shift due to the struggle or shaking of the child. At this time, the caregiver turns on the lighting component 10.
