Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an easy-to-clean dental saliva suction device. Background Technology

[0002] Oral medicine education is the education that trains professionals to engage in oral medical and health care. A standardized training process is an important guarantee for cultivating qualified oral medicine professionals, and strengthening quality supervision is the key to ensuring the quality of education.

[0003] During dental treatments or oral care, saliva, blood, and medications produced during rinsing are present in the mouth. For cases with excessive residual liquid, patients can sit up and spit it out. However, even so, saliva will still be produced slowly during the dentist's treatment, and frequently sitting up or lying down is inconvenient. In order not to affect normal care procedures, a saliva suction device is needed to remove excess liquid from the mouth and drain it out of the mouth.

[0004] However, existing saliva suction devices typically have a tapered end with a grip and a suction tube—usually a thin tube—that draws liquid out of the mouth by suction. Since the mouth contains not only saliva and blood but also solid particles such as food debris, tartar, and tooth fragments, these particles, mixed with thick blood, adhere to the outer wall of the suction tube and cannot be cleaned off. Over time, they harden into blood clots, making them even more difficult to clean. Therefore, there is a need for a saliva suction tube that is clogging-proof and easy to clean. Bacteria adhering to the tip of the suction tube may enter wounds, causing infection and delaying wound healing, thus reducing both the effectiveness and efficiency of the oral saliva suction device. Therefore, an easy-to-clean dental saliva suction device has been proposed to address these problems. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Please see Figure 1-5 The easy-to-clean dental saliva suction device in this embodiment includes a saliva suction device body 1, on which a cleaning mechanism 2 is provided.

[0028] Specifically, the cleaning mechanism 2 includes a first mounting collar 201, which is fixedly mounted on the outside of the saliva suction body 1. Two first mounting rods 202 are fixedly mounted on the outer wall of the first mounting collar 201. The first mounting rods 202 have an internal mounting cavity 203. A second mounting rod 204 is slidably connected inside the mounting cavity 203. A spring 205 is sleeved on the outside of the left second mounting rod 204. An mounting plate 206 is fixedly mounted inside the left mounting cavity 203. A top plate 207 is fixedly mounted on the top of the left second mounting rod 204. A second mounting collar 208 is fixedly mounted on the outside of the saliva suction body 1. A scraper ring 209 is fixedly mounted on the inner wall of the second mounting collar 208. A water collection cavity 210 is opened inside the second mounting collar 208. A water delivery hose 211 is connected to the second mounting collar 208. By setting up the cleaning mechanism 2, when using the saliva suction body 1, impurities in the saliva adhere to the outer wall of the saliva suction body 1. At this time, by pressing the pressing rod 3, the pressing rod 3 will press the top plate 207 when it moves to the bottom. When the top plate 207 moves, it will drive the second mounting rod 202 to move downward, thereby driving the scraping ring 209 to move downward. When the scraping ring 209 moves, it will scrape the surface of the saliva suction body 1. When scraping, the scraping ring 209 will scrape off the particles and impurities adhering to the surface. When scraping off, the water supply hose 211 will deliver water to the water collection chamber 210 and spray it out through the water outlet. At the same time, the water flow will rinse the outer wall of the saliva suction body 1, thereby cleaning the exterior of the saliva suction body 1.

[0029] Specifically, a sliding hole is provided on the mounting plate 206, and the second mounting rod 204 passes through the mounting plate 206 through the sliding hole. When the second mounting rod 204 slides, its outer surface is slidably connected with the sliding hole.

[0030] Specifically, the inner wall of the right mounting cavity 203 is provided with sliding grooves on both sides, and sliders are fixedly installed on both sides of the right second mounting rod 204. The sliders are slidably connected to the sliding grooves, and the bottom end of the second mounting rod 204 is fixedly connected to the second mounting collar 208. By setting the sliding grooves and sliders, the sliding of the second mounting rod 204 can be made more stable.

[0031] Specifically, the second mounting collar 208 has several water outlet holes on the side wall near the mouthpiece of the saliva suction body 1. The water outlet holes are connected to the inside of the water collection chamber 210. The water collection chamber 210 is connected to the water supply hose 211. The water supply hose 211 needs to be connected to an external water source for continuous water supply.

[0032] When implementing this procedure, please follow these steps:

[0033] 1) First, place the saliva suction device 1 inside the mouth to suction and clean saliva, blood, and particles inside the mouth;

[0034] 2) Then connect the water supply hose 211 to the external water supply pipe. If impurities adhere to the outside of the saliva suction body 1 when suctioning saliva, you can press the pressing rod 3. The pressing rod 3 will drive the scraping ring 209 to move. When the scraping ring 209 moves up and down, it can scrape the surface of the saliva suction body 1.

[0035] 3) During the final scraping, the scraping ring 209 scrapes off the particulate impurities adhering to the surface. When scraping off, the water supply hose 211 delivers water to the water collection chamber 210 and sprays it out through the water outlet. At the same time, the water flow washes the outer wall of the saliva suction body 1, thereby cleaning the exterior of the saliva suction body 1.

[0036] In summary, by setting up the cleaning mechanism 2, when using the saliva suction body 1, impurities in the saliva adhere to the outer wall of the saliva suction body 1. At this time, by pressing the pressing rod 3, the pressing rod 3 will drive the scraping ring 209 to move. When the scraping ring 209 moves, it will scrape the surface of the saliva suction body 1. During the scraping, the scraping ring 209 will scrape off the particles and impurities adhering to the surface. When the particles are scraped off, the water supply hose 211 will deliver water to the water collection chamber 210 and spray it out through the water outlet. At the same time, the water flow will rinse the outer wall of the saliva suction body 1, thereby achieving the cleaning of the exterior of the saliva suction body 1.

[0037] Furthermore, this easy-to-clean dental saliva suction device is equipped with a spring 205. When the scraper ring 209 is not used for cleaning, the spring 205 will drive the second mounting ring 208 to pull upward, preventing the second mounting ring 208 from getting too close to the mouthpiece of the saliva suction device body 1 and affecting the suction effect.
