Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a hydrofluoric acid waste treatment device for dental use. Background Technology

[0002] Characteristics of dental hydrofluoric acid: Extremely low concentration: typically 4%-9%. Industrial HF in gel form has a concentration of 30%-70%, significantly reducing the risk of corrosion. Added slow-release agents: Contains thickeners such as silica to control the reaction rate and prevent excessive erosion. Short action time: Rinse immediately 60-120 seconds after application. Clinical procedure: 1. Surface isolation: Isolate the affected tooth with a rubber dam to protect the gums. HF contact with soft tissue can cause necrosis. 2. Precise application: Use a small plastic-tipped brush to apply the gel only to the inner surface of the restoration, avoiding contact with the tooth structure. 3. Neutralization and rinsing: Rinse with a strong water flow for at least 30 seconds, then spray with phosphate buffer to neutralize residual acid. 4. Silanization treatment: Apply a silane coupling agent to form chemical bonds, enhancing the bonding strength between the resin and ceramic.

[0003] Currently, the neutralization and cleaning of the small plastic-headed brush dipped in gel is carried out by using a syringe to draw neutralizing liquid from an open disposable paper cup and rinsing the brush placed in the cup. The odor generated during the neutralization process can easily escape into the space, causing some impact on the operators. Therefore, a hydrofluoric acid waste treatment device for dental use is provided. Utility Model Content

[0004] To address the problem of existing technology: Currently, when neutralizing and cleaning small plastic-headed brushes dipped in gel, the neutralizing solution is drawn from an open disposable paper cup using a syringe and then used to rinse the brushes placed in the cup. The odor generated during the neutralization process can easily escape into the air, causing some impact on the operators.

[0005] A hydrofluoric acid waste treatment device for dental use includes a treatment cup body. A detachable top cover is installed at the end of the treatment cup body. Two through holes are opened at a distance on the top of the top cover. A connector communicating with the inside of the connector is fixedly connected to one of the through holes. A filter device is sleeved on the outer surface of the connector. A rubber gasket is embedded in the other through hole. The filtration device includes a housing, and a connector sleeve adapted to the connector is fixedly connected to the middle of the bottom end of the housing. The inner surface of the connector sleeve communicates with the interior of the housing, and a filter element is installed in the housing.

[0006] Furthermore, the top of the housing is also fixedly connected to an additional connector that communicates with its interior, and the outer surface of the additional connector is connected to a rubber ball.

[0007] Working principle and beneficial effects: By installing a top cover on the treatment cup body, and a filter device is installed in the through hole on the top cover, when the brush placed in the treatment cup body reacts with the neutralizing liquid injected from another through hole, the gas generated will be absorbed by the filter element in the filter device, preventing leakage and improving safety.

[0010] The present invention can be better understood from the following embodiments.

[0011] The structures, proportions, and sizes shown in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, terms such as "upper," "lower," "front," "rear," and "middle" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention. Example

[0012] like Figure 1-2As shown, a hydrofluoric acid waste treatment device for dental use includes a treatment cup body 1. A detachable top cover 2 is installed at the end of the treatment cup body 1. Two through holes 3 are opened at a distance from the top of the top cover 2. A connector 4 communicating with the interior of the top cover 2 is fixedly connected at one of the through holes 3. A filter device is sleeved on the outer surface of the connector 4. A rubber gasket is embedded in the other through hole 3. The filter device includes a housing 5. A connector sleeve adapted to the connector 4 is fixedly connected to the middle of the bottom end of the housing 5. The inner surface of the connector sleeve communicates with the interior of the housing 5. A filter element is installed in the housing 5. By installing a top cover 2 on the treatment cup body 1 and a filter device is also provided in the through hole 3 of the top cover 2, when the brush placed in the treatment cup body 1 reacts with the neutralizing liquid injected from the other through hole 3, the gas generated is absorbed by the filter element in the filter device, preventing leakage and improving safety. In order to reduce costs and facilitate operation, the treatment cup body 1 can be a disposable paper cup, while the components on the top cover 2 can be recycled.

[0013] In the above technical solution, a rubber ball 7 is also provided on the top of the housing 5 of the filter device. The specific structure is as follows: the top of the housing 5 is also fixedly connected to an additional connector 6 that communicates with the interior. The outer surface of the additional connector 6 is connected to the rubber ball 7. During installation, the rubber ball 7 is kept in a compressed state, for example, by using a clamp. When the neutralizing liquid is injected, the clamp is removed and the rubber ball 7 will return to its original shape, so as to promote the gas in the treatment cup body 1 to enter the filter device and improve the purification effect.
