Description

Technical Field

[0001] The utility model relates to the technical field of dental handpieces, in particular to a device for monitoring the cleaning effect of dental handpieces. Background Art

[0002] Dental handpieces are commonly used tools in dental diagnosis and treatment. When in use, dental handpieces are directly in contact with the saliva, blood, teeth, etc. of oral patients. Therefore, in order to avoid cross-infection, dental handpieces need to be cleaned and disinfected after use. However, it is found in actual use that there are many pipelines in dental handpieces, and many water channels and pipelines are relatively narrow, making it difficult to clean; at the same time, there are multiple lumens inside the pipelines that are difficult to see from the outside. Therefore, after cleaning the dental handpiece, it is difficult to determine whether the blood in the lumens and each channel has been completely cleaned.

[0003] Since the blood of different people contains different viruses and bacteria, incomplete cleaning of dental handpieces is likely to cause cross-infection to patients who use them later. To ensure the disinfection and sterilization effect of medical devices, medical devices must be thoroughly cleaned. Therefore, it is necessary to monitor the cleaning effect of the cleaning machine. Using a cleaning effect monitoring card to monitor the cleaning effect of the cleaning machine is more intuitive and easy to store and trace. At the same time, with the standardization and regularization of medical device cleaning, medical staff pay more and more attention to the cleaning effect of medical devices. After monitoring the cleaning effect, the cleaning effect monitoring card will be pasted and recorded for traceability. However, the existing technology can only monitor the cleaning effect of the outer surface of dental handpieces and cannot monitor the cleaning effect inside dental handpieces.

[0023] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions of the present utility model in conjunction with the embodiments of the present utility model.

[0024] Embodiment 1

[0025] As Figure 1 shown, this embodiment provides a device for monitoring the cleaning effect of a dental handpiece, including a connector 1, an intermediate connector 2, and an end connector 3 that are sequentially threadedly connected end to end. As Figures 2 - 4 shown, a through first cavity 101 is provided inside the connector 1, a second cavity 201 and a third cavity 301 are respectively provided inside the intermediate connector 2 and the end connector 3, liquid inlets and outlets are respectively provided at both ends of the intermediate connector 2 and the end connector 3, the liquid inlet of the second cavity 201 is smaller than the outlet, the liquid inlet of the third cavity 301 is larger than the outlet, and the first cavity 101, the second cavity 201, and the third cavity 301 are communicated through the liquid inlets and outlets. As Figures 3 - 4 shown, a monitoring card 4 is placed in the second cavity 201 and the third cavity 301, and the monitoring card 4 is larger than the outlet of the third cavity 301. As Figure 5 shown, the monitoring card 4 includes a card body 401, the card body 401 is made of a stainless steel sheet, and a simulated contaminant layer 402 is provided on one side of the card body 401.

[0026] Among them, the simulated contaminant layer 402 can be made of a cleaning effect monitoring simulated contaminant and its preparation method and application disclosed in Chinese invention patent CN115855140A, and the simulated contaminant in Example 1 of the cleaning effect monitoring card. Specifically, the simulated contaminant includes the following components by mass percentage: 24% bone glue, 5% zein, 2% starch, 0.5% allura red, 3% sucrose fatty acid ester, 5% polyethylene glycol, 40.5% water, and 20% ethanol. The preparation method of the simulated contaminant includes the following steps:

[0027] S1 Add bone glue, polyethylene glycol, starch, and allura red to water, and heat and dissolve at 60°C to obtain the first dissolved solution;

[0028] S2 Add zein and sucrose fatty acid ester to ethanol, and dissolve at 25°C to obtain the second dissolved solution;

[0029] S3 mixes Solution 1 and Solution 2, stirs them at 500 rpm for 3 h to obtain a simulated pollutant.

[0030] The preparation method of the monitoring card 4 is as follows: The simulated pollutant is printed on one side of a stainless-steel sheet by a screen printing machine, dried at 60 °C, and then cut to obtain the monitoring card 4.

[0031] Working principle:

[0032] Two monitoring cards 4 are respectively placed into the intermediate connector 2 and the end connector 3 from the liquid outlet of the cavity 201 and the liquid inlet of the cavity 301. Subsequently, the adapter, the intermediate connector 2, and the end connector 3 are sequentially thread-connected, and the adapter is located at the top. When in use, the adapter is connected to a dental handpiece cleaning device, and a cleaning solution prepared by mixing a cleaning enzyme and distilled water is injected into the cavity 101 of the adapter by the dental handpiece cleaning device to simulate the cleaning process of a dental handpiece. The cleaning solution flows through the two monitoring cards 4 of the intermediate connector 2 and the end connector 3 in sequence, and then is discharged from the liquid outlet of the end connector 3. The two monitoring cards 4 can respectively simulate and verify the cleaning effects at the middle and tail positions of the dental handpiece. After cleaning is completed, the monitoring card 4 is taken out, and it is observed whether the simulated pollutant is cleaned to judge whether the inside of the dental handpiece can be cleaned when cleaning the dental handpiece.

[0033] Example 2

[0034] On the basis of Example 1, as Figure 4 、 7 shown, a support block 5 is placed inside the end connector 3. The size of the support block 5 is smaller than the liquid inlet of the end connector 3 but larger than the liquid outlet of the end connector 3, and two clamping blocks 501 are arranged on the support block 5, and the monitoring card 4 is clamped between the two clamping blocks 501.

[0035] When placing the monitoring card 4 into the end connector 3, the support block 5 is poured out from the liquid inlet of the end connector 3, the monitoring card 4 is clamped between the two clamping blocks 501, and then it is placed into the cavity 301. At the same time, in order to prevent the support block 5 from blocking the liquid outlet of the end connector 3, its structure can be designed as a hollow structure to ensure that the cleaning solution is smoothly discharged from the liquid outlet of the end connector 3.

[0036] Example 3

[0037] On the basis of Example 1, as Figure 3 、 6 shown, a support plate 6 is fixed at the liquid outlet of the intermediate connector 2. A circular through-hole 601 is arranged on the support plate 6, and the diameter of the circular through-hole 601 is smaller than the width of the monitoring card 4; notches 602 are respectively arranged on the opposite sides in the diameter direction of the circular through-hole 601, and the monitoring card 4 can enter the cavity 201 through the channel formed by the notch 602 and the circular through-hole 601.

[0038] When inserting the monitoring card 4 into the intermediate connector 2, align the left and right sides of the monitoring card 4 with the two notches 602 respectively, so as to insert the monitoring card 4 into the cavity two 201. After the monitoring card 4 is inserted, in order to prevent it from falling down into the lower end connector 3, when inserting, the lower end of the monitoring card 4 can be staggered from the notch 602 position of the support plate 6, so that the monitoring card 4 is placed obliquely in the cavity two 201.

[0039] Example 4

[0040] On the basis of Example 1, as Figure 1 shown, anti-slip patterns 7 are respectively arranged on the outer walls of the intermediate connector 2 and the end connector 3, which is convenient for screwing the intermediate connector 2 and the end connector 3 and facilitates the operation.
