Description

Technical Field

[0001] This invention relates to the field of oral foreign body adsorption technology, specifically to an oral clinical foreign body adsorption device. Background Technology

[0002] The definition of clinical dentistry mainly refers to a branch of oral medicine, namely clinical dentistry. This is a comprehensive discipline that studies various diseases of human teeth and dentition, oral soft and hard tissues, and maxillofacial and cervical diseases. A foreign body adsorption device in clinical dentistry is a device used to adsorb and remove foreign bodies from the oral cavity during oral treatment. This device is commonly used in dental restorations, oral surgery, and other scenarios. It can effectively remove impurities such as saliva, blood, and debris from the oral cavity, maintain a clear surgical field, and improve treatment outcomes.

[0003] As disclosed in Chinese Patent CN216877009U, the oral foreign body adsorption device for clinical use involves placing an infant with a foreign body in their mouth face down on a pad, with their legs spread out on a leg rest and their abdomen against the inside of the pad, ensuring their mouth and nose are directly above the opening. The angle of the support and pad is adjusted using an electric push rod to ensure the infant's head is facing downwards and their legs upwards. Simultaneously, the infant is gently tapped several times from their back to their neck and then towards their head, while the foreign body is removed through the opening. The operator observes whether the foreign body has been expelled from the infant's mouth. Depending on the situation, a vacuum adsorption device can be used in conjunction. This process is repeated several times until the foreign body is expelled and the infant returns to normal. This relatively stable face-down position allows the infant to cooperate with oral clinical treatment, reducing the difficulty of the rescuer's operation, increasing the speed and effectiveness of treatment, promptly eliminating danger, and saving the infant's life.

[0004] While this structure allows for adjustment of the patient's posture during foreign body adsorption, the adsorption head is a disposable item, making it inconvenient to quickly replace the adsorption head and affecting the speed of treatment. Therefore, we propose an oral foreign body adsorption device for clinical use that allows for quick replacement of the adsorption head to improve the speed of treatment. Summary of the Invention

[0005] The purpose of this invention is to provide a dental foreign body adsorption device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an oral foreign body adsorption device for clinical use, comprising an adsorption mechanism, a connecting tube connected to the outer wall of the adsorption mechanism, an adsorption head snapped onto the end of the connecting tube, and a processing component disposed outside the connecting tube, the processing component including a replacement component disposed outside the connecting tube, a sealing component disposed inside the replacement component, and an auxiliary component disposed outside the sealing component.

[0007] Preferably, the replacement component includes a fixing plate fixedly installed on the outer wall of the connecting pipe, a clamping plate hinged to the inner side of the fixing plate, a first inclined block fixedly installed on the outer wall of the clamping plate, a spring fixedly installed on the side of the clamping plate away from the first inclined block, a slide rail provided below the fixing plate, a slide plate slidably provided on the outer wall of the slide rail, a pull ring fixedly installed at the end of the slide plate, a second inclined block fixedly installed on the inner wall of the pull ring, and a clamping block fixedly installed on the outer wall of the suction head.

[0008] Preferably, the sealing assembly includes a fixing ring fixedly installed at the end of the connecting tube away from the adsorption mechanism, a sealing ring fixedly installed on the side of the fixing ring away from the connecting tube, a limiting hole being formed inside the sealing ring, a sealing groove being formed at the end of the adsorption head, and a limiting rod being fixedly installed on the inner wall of the sealing groove.

[0009] Preferably, the auxiliary component includes a first locking pin that is snapped into the inside of the fixing plate, a retaining ring fixedly installed on the outer wall of the first locking pin, a first magnetic ring fixedly installed on the side wall of the first locking pin, a second locking pin that is snapped into the inside of the first magnetic ring, and a second magnetic ring fixedly installed on the outer wall of the second locking pin.

[0010] Preferably, the second inclined block is in contact with the inclined surface of the first inclined block, and the slide plate fixedly installed on the inner wall of the pull ring is slidably installed on the outer wall of the connecting pipe. Under the restriction of the slide, the pull ring drives the second inclined block to stably compress the first inclined block.

[0011] Preferably, the end of the spring away from the clamping plate is fixedly installed to the outer wall of the connecting tube. There are four clamping plates, which are arranged in a cross shape around the center of the connecting tube. Under their constraint, the adsorption head and the connecting tube can be installed quickly.

[0012] Preferably, the limiting rod and the limiting hole are appropriately matched, and the sealing ring is made of rubber. Under the restriction of the limiting rod and the limiting hole, the card block and the card plate can slide and squeeze accurately. Under the restriction of the rubber material of the sealing ring, the connection between the adsorption head and the connecting tube can be sealed.

[0013] Preferably, the first magnetic ring and the second magnetic ring are magnetically attracted to each other, and the second locking pin is slidably disposed inside the first magnetic ring. Under the restriction of magnetic attraction, the second locking pin can be stably locked inside the first locking pin.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This oral cavity foreign body adsorption device for clinical use comprises a replaceable component. When it is necessary to disassemble the adsorption head and connecting tube, the auxiliary component is removed, and then the pull ring is pulled away from the adsorption head. At this time, the inclined surface of the second inclined block fixedly installed on the inner wall of the pull ring contacts and presses against the inclined surface of the first inclined block fixedly installed on the outer wall of the clamping plate, causing the clamping plate to rotate around the hinge point with the fixed plate as the rotation center, so that the end of the clamping plate is no longer locked with the outer wall of the clamping block, and the adsorption head can be disassembled. When it is necessary to install the adsorption head, the limiting rod in the sealing component is aligned with the limiting hole and sleeved. The inclined surface of the clamping block fixedly installed on the outer wall of the adsorption head contacts and presses against the inclined surface of the clamping plate, causing the spring fixedly installed on the end of the clamping plate to compress. When the clamping block is no longer pressed against the clamping plate, the clamping plate is locked with the clamping block under the elastic action of the spring. This structure allows for quick disassembly and assembly of the adsorption head and connecting tube, thereby improving the speed of treatment.

[0015] 2. This oral clinical foreign body adsorption device consists of a sealing component. When it is necessary to install the adsorption head and the connecting tube, the limiting rod is aligned with the limiting hole so that the sealing groove at the end of the adsorption head is fitted with the fixing ring at the end of the connecting tube. Under the restriction of the sealing ring, the connection between the connecting tube and the adsorption head can be sealed to improve the foreign body adsorption effect.

[0016] 3. The oral foreign body adsorption device for clinical use is composed of auxiliary components. When foreign body adsorption is performed, in order to prevent the adsorption head from falling off the connecting tube, the first locking pin is engaged with the fixed plate to prevent the locking plate from rotating inside the fixed plate. Then, the second locking pin is engaged with the inside of the first magnetic ring. Under the magnetic attraction between the first and second magnetic rings, the first locking pin can be prevented from falling off the inside of the fixed plate. This structure can restrict the rotation of the locking plate and prevent the adsorption head from falling off the connecting tube. Attached Figure Description

Detailed Implementation

[0026] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0027] Example 1: A preferred embodiment of the oral foreign body adsorption device provided by the present invention is as follows: Figures 1 to 8 As shown: an oral cavity foreign body adsorption device for clinical use, including an adsorption mechanism 1; The outer wall of the adsorption mechanism 1 is connected to a connecting pipe 2; The end of the connecting tube 2 is clamped with an adsorption head 3; The processing assembly 4 is located outside the connecting pipe 2. The processing assembly 4 includes a replacement assembly 41 located outside the connecting pipe 2. The replacement assembly 41 includes a fixed plate 411 fixedly installed on the outer wall of the connecting pipe 2. A clamping plate 412 is hinged to the inner side of the fixed plate 411. A first inclined block 413 is fixedly installed on the outer wall of the clamping plate 412. A spring 414 is fixedly installed on the side of the clamping plate 412 away from the first inclined block 413. A slide 415 is provided below the fixed plate 411. A slide plate 416 is slidably provided on the outer wall of the slide 415. A pull ring 417 is fixedly installed at the end of the slide plate 416. A second inclined block 418 is fixedly installed on the inner wall of the pull ring 417. A clamping block 419 is fixedly installed on the outer wall of the suction head 3.

[0028] In this embodiment, when it is necessary to disassemble the adsorption head 3 and the connecting tube 2, the auxiliary component 43 is removed, and then the pull ring 417 is pulled away from the adsorption head 3. At this time, the inclined surface of the second inclined block 418 fixedly installed on the inner wall of the pull ring 417 contacts and presses against the inclined surface of the first inclined block 413 fixedly installed on the outer wall of the clamping plate 412, so that the clamping plate 412 rotates around the hinge point with the fixed plate 411 as the rotation center, so that the end of the clamping plate 412 is no longer clamped to the outer wall of the clamping block 419, and the adsorption head 3 can be disassembled. When installing the adsorption head 3, the limiting rod 425 in the sealing assembly 42 is aligned with the limiting hole 423 and fitted. The inclined surface of the locking block 419 fixedly installed on the outer wall of the adsorption head 3 contacts and presses against the inclined surface of the locking plate 412, causing the locking plate 412 to compress the spring 414 fixedly installed at its end. When the locking block 419 no longer presses against the locking plate 412, the locking plate 412 and the locking block 419 are engaged under the elastic action of the spring 414. This structure allows for quick assembly and disassembly of the adsorption head 3 and the connecting tube 2, thereby improving the speed of treatment.

[0029] Example 2: Based on Example 1, a preferred embodiment of the oral foreign body adsorption device for clinical oral use provided by the present invention is as follows: Figures 1 to 8 As shown: The sealing assembly 42 includes a fixing ring 421 fixedly installed on the end of the connecting pipe 2 away from the adsorption mechanism 1. A sealing ring 422 is fixedly installed on the side of the fixing ring 421 away from the connecting pipe 2. A limit hole 423 is opened inside the sealing ring 422. A sealing groove 424 is opened at the end of the adsorption head 3. A limit rod 425 is fixedly installed on the inner wall of the sealing groove 424.

[0030] In this embodiment, when it is necessary to install the adsorption head 3 and the connecting tube 2, the limiting rod 425 is aligned with the limiting hole 423, so that the sealing groove 424 opened at the end of the adsorption head 3 and the fixing ring 421 fixedly installed at the end of the connecting tube 2 are fitted together. Under the restriction of the sealing ring 422, the connection between the connecting tube 2 and the adsorption head 3 can be sealed to improve the adsorption effect of foreign matter.

[0031] Example 3: Based on Example 1, a preferred embodiment of the oral foreign body adsorption device for clinical oral use provided by the present invention is as follows: Figures 1 to 8 As shown: The auxiliary component 43 includes a first locking pin 431 that is snapped into the inside of the fixed plate 411. A retaining ring 432 is fixedly installed on the outer wall of the first locking pin 431. A first magnetic ring 433 is fixedly installed on the side wall of the first locking pin 431. A second locking pin 434 is snapped into the inside of the first magnetic ring 433. A second magnetic ring 435 is fixedly installed on the outer wall of the second locking pin 434.

[0032] In this embodiment, when foreign matter adsorption is in progress, to prevent the adsorption head 3 from falling off the connecting tube 2, the first locking pin 431 is locked onto the fixing plate 411 to prevent the locking plate 412 from rotating inside the fixing plate 411. Then, the second locking pin 434 is locked onto the inside of the first magnetic ring 433. Under the magnetic attraction between the first magnetic ring 433 and the second magnetic ring 435, the first locking pin 431 can be prevented from falling off the inside of the fixing plate 411. This structure can restrict the rotation of the locking plate 412 and prevent the adsorption head 3 from falling off the connecting tube 2.

[0033] Furthermore, the second inclined block 418 is in contact with the inclined surface of the first inclined block 413. The slide plate 416 fixedly installed on the inner wall of the pull ring 417 and the slide bracket 415 fixedly installed on the outer wall of the connecting pipe 2 are slidably arranged. Under the restriction of the slide bracket 415, the pull ring 417 drives the second inclined block 418 to stably squeeze the first inclined block 413. The end of the spring 414 away from the clamping plate 412 is fixedly installed on the outer wall of the connecting pipe 2. There are four clamping plates 412, which are distributed in a cross shape around the center of the connecting pipe 2. Under their restriction, the adsorption head 3 can be quickly installed on the connecting pipe 2.

[0034] Furthermore, the limiting rod 425 and the limiting hole 423 are appropriately matched, and the sealing ring 422 is made of rubber. Under the restriction of the limiting rod 425 and the limiting hole 423, the card block 419 and the card plate 412 can slide and squeeze precisely. Under the restriction of the rubber material of the sealing ring 422, the connection between the adsorption head 3 and the connecting tube 2 can be sealed.

[0035] In addition, the first magnetic ring 433 and the second magnetic ring 435 are magnetically attracted to each other, and the second locking pin 434 is slidably disposed inside the first magnetic ring 433. Under the restriction of magnetic attraction, the second locking pin 434 can be stably locked inside the first locking pin 431.

[0036] The above are merely illustrative embodiments of the present invention and are not intended to limit the scope of the invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention should fall within the scope of protection of the present invention. Furthermore, it should be noted that the components of the present invention are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, the present invention naturally covers other combinations and specific applications related to the inventive points of this case.
