Description

Technical Field

[0001] This utility model relates to the field of dental medical device technology, and in particular to a dental impression infusion device. Background Technology

[0002] In the field of oral healthcare, impression taking is a crucial step in various treatments such as dental restoration and orthodontics. Traditional dental impression infusion devices have many shortcomings in their structural design. The connection between the discharge tube and the main structure is either cumbersome to disassemble due to threaded connections or lacks sufficient stability. Poorly stable connections are prone to displacement, shaking, or even detachment of the discharge tube under frequent intraoral manipulations and instrument collisions, causing inconvenience during use. Furthermore, traditional dental impression infusion devices lack effective anti-misoperation mechanisms. During preparation or operation, accidental touches by medical staff or improper instrument placement often lead to premature infusion of impression material, potentially resulting in waste of impression material or requiring re-operation due to failed impression taking, increasing patient pain and discomfort. Therefore, we have introduced a new dental impression infusion device. Utility Model Content

[0003] The main objective of this invention is to provide an oral impression infusion device that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An oral impression infusion device includes an infusion cylinder, an output tube at the middle of the right end of the infusion cylinder, a connecting seat at the right end of the output tube, a slot at the middle of the right end of the connecting seat, corresponding grooves at the upper and lower parts of the right end of the connecting seat, and fixing grooves at the front and rear parts of the right end of the connecting seat. The two corresponding grooves and the two fixing grooves are all connected to the interior of the slot. An infusion assembly is disposed within the interior of the slot, the two corresponding grooves, and the two fixing grooves. A locking hole is provided on the inner wall of the two fixing grooves away from the slot. An anti-mispush device is threadedly connected to the left side of the outer surface of the infusion cylinder. A push rod is movably mounted on the inner surface of the infusion cylinder, and a push plate is provided at the left end of the push rod.

[0006] Preferably, the infusion assembly includes a discharge pipe, an extension pipe is provided on the left side of the inner surface of the discharge pipe, corresponding blocks are provided on the upper left and lower left sides of the outer surface of the discharge pipe, fixing blocks are provided on the front left and rear left sides of the outer surface of the discharge pipe, springs are fixedly installed inside the two fixing blocks through inner grooves, driving blocks are movably installed inside the two fixing blocks through inner grooves, and a locking block is provided at the end of the two driving blocks away from the springs.

[0007] Preferably, the discharge pipe is movably inserted into the inside of the output pipe via an extension pipe, and the discharge pipe is connected to the inside of the injection cylinder via the extension pipe and the output pipe.

[0008] By adopting the above technical solution, it is ensured that the impression material can be smoothly transported from the injection cylinder through the discharge pipe, extension pipe and output pipe to the target position in the oral cavity.

[0009] Preferably, the discharge pipe is movably connected to the inside of two corresponding slots via corresponding blocks.

[0010] By adopting the above technical solution, the cooperation between the corresponding block and the corresponding groove can play a certain role in positioning and preventing rotation, ensuring that the discharge pipe will not shake or twist randomly during normal use.

[0011] Preferably, the fixing block is movably engaged inside the fixing groove, and the locking block is movably engaged inside the locking hole by a spring.

[0012] By adopting the above technical solution, the locking block is engaged with the inside of the locking hole by a spring, which facilitates quick locking and unlocking, achieves a stable locking state, and prevents the parts from accidentally dislodging.

[0013] Preferably, the anti-mispush device includes a fixed sleeve, an mounting sleeve is provided on the left side of the inner surface of the fixed sleeve, a screw is threadedly installed on the front side of the outer surface of the mounting sleeve, a limit plate is movably installed on the rear side of the outer surface of the screw through a movable sleeve, and a rotating block is provided at the front end of the screw.

[0014] By adopting the above technical solution: the fixed sleeve is used to install the entire anti-mispush device on the injection cylinder or other main structure, providing a stable support foundation. The function of the screw is to adjust the position of the limiting plate by rotating. When the rotating block at the front end of the screw is rotated, the screw will move back and forth in the mounting sleeve, thereby driving the movable sleeve and the limiting plate to move.

[0015] Preferably, the limiting plate has a semi-arc structure, and the inner surface of the limiting plate is closely fitted with the outer surface of the push rod.

[0016] By adopting the above technical solution, the semi-circular structure allows the limiting plate to tightly hold the push rod, thereby restricting its accidental movement and preventing accidental push.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. A stable connection is achieved through the structure of extension tube, corresponding block, fixing block and spring clip. The snapping of the corresponding block with the corresponding slot can effectively limit the rotation and partial displacement of the discharge tube. The fixing block, with the cooperation of the spring clip with the fixing slot and the snap hole, further enhances the stability of the connection and prevents the discharge tube from loosening or falling off due to external force or vibration during the injection process. This ensures that the impression material can be accurately delivered to the target position in the oral cavity, improving the success rate and accuracy of impression making. At the same time, simply press the drive block to overcome the spring force and let the clip disengage from the snap hole, and the fixing block can be pulled out from the fixing slot. Then the discharge tube can be taken out from the corresponding slot and the output tube, which is convenient for installation and disassembly. It is easy to replace the discharge tube according to actual needs, so as to adapt to different needs.

[0019] 2. In the initial state, the limiting plate installed on the infusion cylinder by the fixing sleeve is tightly attached to the push rod. Due to its semi-circular structure and close contact with the outer surface of the push rod, it can effectively limit the accidental movement of the push rod, avoiding adverse consequences such as waste of impression material, failure of impression making, or even damage to the patient's oral cavity due to misoperation. This improves the safety and reliability of the entire impression making process. During infusion, by simply rotating the rotating block, the screw and the threaded engagement of the mounting sleeve can drive the limiting plate to move, thereby releasing the restriction on the push rod. Then, the push rod can be smoothly pushed to deliver the impression material. The operation method ensures both safety and convenience, making it easy to use. Attached Figure Description

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] An oral impression infusion device includes an infusion cylinder 1, an output tube 2 at the middle of the right end of the infusion cylinder 1, a connecting seat 3 at the right end of the output tube 2, a slot 4 at the middle of the right end of the connecting seat 3, corresponding grooves 5 at the upper and lower parts of the right end of the connecting seat 3, and fixing grooves 6 at the front and rear parts of the right end of the connecting seat 3. The two corresponding grooves 5 and the two fixing grooves 6 are connected to the interior of the slot 4. An infusion component 7 is provided inside the slot 4 and the interiors of the two corresponding grooves 5 and the two fixing grooves 6. The inner walls of the two fixing grooves 6 away from the slot 4 are provided with locking holes 8. An anti-mispush device 9 is threadedly connected to the left side of the outer surface of the infusion cylinder 1. A push rod 10 is movably installed on the inner surface of the infusion cylinder 1, and a push plate 11 is provided at the left end of the push rod 10.

[0030] In this embodiment, the infusion assembly 7 includes a discharge pipe 71. An extension pipe 72 is provided on the left side of the inner surface of the discharge pipe 71. Corresponding blocks 73 are provided on the upper left and lower left sides of the outer surface of the discharge pipe 71. Fixing blocks 74 are provided on the front left and rear left sides of the outer surface of the discharge pipe 71. Springs 75 are fixedly installed inside the two fixing blocks 74 through inner grooves. Driving blocks 76 are movably installed inside the two fixing blocks 74 through inner grooves. A locking block 77 is provided at the end of the two driving blocks 76 away from the springs 75. The discharge pipe 71 is movably inserted into the inside of the output pipe 2 through the extension pipe 72. The discharge pipe 71 is connected to the inside of the infusion cylinder 1 through the extension pipe 72 and the output pipe 2. The discharge pipe 71 is movably locked inside the two corresponding grooves 5 through the corresponding blocks 73. The fixing blocks 74 are movably locked inside the fixing grooves 6. The locking blocks 77 are movably locked inside the locking holes 8 through the springs 75.

[0031] With the above solution: during installation, the extension tube 72 of the discharge tube 71 is inserted into the output tube 2 to achieve connection and allow for position adjustment. The corresponding block 73 is inserted into the corresponding slot 5 to restrict the rotation and excessive displacement of the discharge tube 71. The fixing block 74 is inserted into the fixing slot 6, and the spring 75 pushes the drive block 76 to make the locking block 77 lock into the locking hole 8, thus completing the fixation and ensuring the stable connection of the discharge tube 71. During disassembly, press the drive block 76 to make the locking block 77 disengage from the locking hole 8.

[0032] In this embodiment, the anti-mispush device 9 includes a fixed sleeve 91, an installation sleeve 92 is provided on the left side of the inner surface of the fixed sleeve 91, a screw 93 is threadedly installed on the front side of the outer surface of the installation sleeve 92, a limit plate 95 is movably installed on the rear side of the outer surface of the screw 93 through a movable sleeve, and a rotating block 94 is provided at the front end of the screw 93; the limit plate 95 has a semi-arc structure, and the inner surface of the limit plate 95 is tightly fitted with the outer surface of the push rod 10.

[0033] With the above solution: the fixed sleeve 91 fixes the screw 93 initially, so that the limiting plate 95 tightly holds the push rod 10, restricting its accidental movement. When in use, rotating the rotating block 94 drives the screw 93 to move, and the movable sleeve causes the limiting plate 95 to release the push rod 10, thus releasing the restriction. This allows for the normal pushing operation of the molding material, thereby preventing the molding material from being prematurely injected or the injection speed from going out of control due to accidental contact or other reasons during the preparation stage.

[0034] It should be noted that this utility model is an oral impression infusion device. During use, firstly, align the extension tube 72 at the left end of the discharge tube 71 of the infusion assembly 7 with the inside of the output tube 2, and then insert it, so that the discharge tube 71 is connected to the inside of the infusion cylinder 1 through the extension tube 72 and the output tube 2. Next, align and insert the two corresponding blocks 73 and two fixing blocks 74 on the outer surface of the discharge tube 71 into the two corresponding slots 5 and two fixing slots 6 respectively. During insertion, the spring 75 inside the fixing block 74 pushes the driving block 76, causing the locking block 77 at one end of the driving block 76 to be movably engaged in the locking hole 8 on the inner wall of the fixing slot 6 through the spring 75, thus completing the stable connection between the discharge tube 71 and the connecting seat 3. Then, through... The fixing sleeve 91 of the anti-mispush device 9 is pre-threaded to the left side of the outer surface of the infusion cylinder 1. In the initial state, due to the tight restriction of the push rod 10 by the limiting plate 95, the push rod 10 cannot move at will, effectively preventing the accidental infusion of the impression material. When the impression material needs to be infused, the rotating block 94 is rotated, and the screw 93 moves back and forth due to the thread engagement with the mounting sleeve 92. In turn, the limiting plate 95 is moved through the movable sleeve, so that it releases the restriction on the push rod 10. At this time, the push rod 10 can be pushed to the left. The push plate 11 at the left end of the push rod 10 pushes the impression material in the infusion cylinder 1. The impression material is transported to the corresponding part of the oral cavity through the output pipe 2 and the discharge pipe 71 for impression making operation.
