Description

A cuspidor for measuring contamination and a dental unit chair including the cuspidor and ventilation means {A DENTAL UNIT CHAIR COMPRISING A CUSPIDOR FOR MEASURING THE DEGREE OF CONTAMINATION AND A SPITTOON AND VENTILATION MEANS}

The present invention relates to a cuspidor for measuring contamination and a dental unit chair including the cuspidor and ventilation means. More specifically, a cuspidor is provided to reduce secondary contamination caused by the use of a cuspidor and improve the hygiene of patients and hospitals by measuring and controlling contamination of saliva, blood, etc. collected from patients. In addition, a dental unit equipped with the above cuspidor and means to improve patient convenience is provided. This is to ensure more comfortable and hygienic treatment.

A dental unit chair is equipment for accommodating a patient at a dental clinic, etc., and generally includes a headrest to support the patient's head, a backrest to support the patient's back, and a leg rest to support the buttocks and legs. Typically, patients receive treatment while lying down in a unit chair. In addition, it may include a stand (treatment table or doctor table) for holding dental surgical instruments such as handpieces, a toothbrushing fountain and cuspidor that supplies water so that the examinee can wash saliva or the oral cavity, etc. You can.

In addition, the dental unit chair can be equipped with a lighting device to illuminate the inside of the oral cavity, a unit chair monitor arm that shows the inside of the oral cavity, displays CT image information, or installs a monitor for watching TV, a table for patient convenience, etc. there is.

The various devices or instruments installed in the unit chair are installed to have an efficient movement line to provide sufficient functions during the procedure and the patient or operator's movement and convenience, and are provided for convenient operation.

As described above, the dental unit chair is equipped with a doctor's table on which the operator can place and operate various treatment instruments. The doctor table may be installed, for example, on a pole provided on a unit chair.

The pole is provided with a balance arm, and the doctor table can be supported by the balance arm. By using the balance arm, the doctor's table can be moved to the desired position by the operator and maintained in that position. The balance arm is a device that can perform three-dimensional movements, including horizontal as well as vertical movements. This three-dimensional movement of the balance arm moves the doctor's table to the height desired by the operator.

The cuspidor is equipped with a cuspidor and is installed on the unit chair body so that the patient can spit out saliva or foreign substances accumulated in the mouth after receiving treatment or during treatment. Since it is used for spitting out and rinsing the mouth, if it is not cleaned regularly, it can easily become unclean and cause severe discomfort to the patient.

In particular, given the recent trend of continued spread of infectious diseases, the hygiene of the cuspidor is not simply a matter of hygiene or cleanliness of patients or hospitals, but can become a problem that causes secondary infections.

Therefore, a means is needed to manage the cuspidor more hygienically while preventing problems such as secondary infection due to contamination of the cuspidor.

In general, unit chairs designed around doctors cause considerable discomfort to patients, and in particular, patients often become quite nervous due to fear or resistance to dental treatment. Therefore, it is necessary to provide additional means to ensure that patients in the unit chair are psychologically stable.

In this regard, prior art 1 (KR 20-0376400 Y1) discloses a cuspidor for a unit chair that can be separated and washed. However, in the case of prior art 1 above, the cuspidor can be kept clean by removing and washing the cuspidor, but there is the inconvenience of having to separate and clean the cuspidor after each treatment.

In addition, prior art 2 (KR 10-2015-0096259 A) provides a headrest for a dental unit chair and discloses a means for adjusting the length of the upper headrest and providing a comfortable feeling to the patient. . In addition, natural ventilation is induced through the laryngeal receptor pores. However, the upper laryngeal receiving hole is a large hole formed on the headrest to allow natural wind to pass through, which is different from the configuration of the present invention and solves the problem of the present invention to provide a comfortable atmosphere for the mind and body to the patient during the patient's treatment process. It is different from the principle.

The dental unit chair according to the present invention includes a frame 100, a seat 200, a cuspidor 300, a water supply unit 400, and a light 500.

The frame 100 serves as a framework to support the seat 200, the cuspidor 300, and the water supply unit 400. Since it is a known technology included in a general dental unit chair, detailed description will be omitted.

The sheet 200 is coupled to the frame 100 and serves to support the patient. As an example, the sheet 200 includes a first sheet 210, a second sheet 220, and a third sheet 230, where the first sheet 210 covers the patient's lower body, and the second sheet 220 covers the patient's lower body. The third sheet 230 serves to support the patient's upper body and the patient's head.

Please refer to Figure 5. Figure 5 is an enlarged side view of the vicinity of the first seat 210 of the dental unit chair according to the present invention.

A plurality of ventilation means may be coupled to the seat of the dental unit chair according to the present invention. As an example, in FIG. 5 it is shown that a plurality of ventilation means 211 are formed based on the first sheet 210, but the ventilation means can be formed in the same way on the second sheet 220 and the third sheet 230. there is.

The ventilation means 211 is spaced apart from the first sheet 210 at a predetermined interval, but is preferably formed to penetrate the first sheet 210, and the wind A comes out through the ventilation means 211. desirable. In addition, the ventilation means 211 is coupled with a motor (not shown) that enables blowing, and it is preferable that whether or not blowing occurs and the degree of blowing are controlled by a control unit to be described later.

In this way, due to the configuration in which a plurality of ventilation means are coupled to the sheet 200, psychological stability is provided to the patient during dental treatment, thereby minimizing fear of dental treatment.

The cuspidor 300 and the water supply unit 400 will be described in detail later, and the light 500 serves to provide light for the convenience of treatment for the user.

Figure 2 shows a side cross-sectional view of the cuspidor 300 according to the present invention. Hereinafter, the configuration of the cuspidor 300 according to the present invention will be described with reference to FIG. 2.

The cuspidor 300 according to the present invention includes a main body 310, a first drain 320, a second drain 330, a door 340, a sensor 350, a first drain 360, It is preferable to include a second drainage channel 370, a cage 380, and an LED unit 390.

The main body portion 310 is preferably formed with a hollow portion, and has a shape that narrows in width from the top to the bottom. Additionally, it is preferable that the cross-section in the longitudinal and width directions is circular or oval.

In general, a patient after dental treatment spits the saliva directly into the main body 310, or receives water in a cup from the water supply unit 400 and spits the saliva into the main body 310 after pouring it from the patient's mouth. In the conventional case, hygiene problems occurred because the cuspidor that accommodates the cuspid fluid does not have a means for cleaning or a separate means for detecting the degree of contamination. However, the present invention seeks to solve the conventional problem through a configuration that will be described later.

A first drain portion 320 is formed at the lowermost portion of the main body portion 310. The first drain 320 preferably has a shape in which the cross-section in the longitudinal and width directions becomes narrower from the top to the bottom, so that the batted fluid can collect in the center of the first drain 320. It forms a structure that facilitates the discharge of saliva.

The first drain 320 communicates with the first drain 360. The first drainage channel 360 preferably communicates with the center of the first drainage unit 320. Preferably, the upper end of the first drain 360 communicates with the first drain 320, and the lower end of the first drain 360 communicates with the cage 380.

The cage 380 is in communication with the first drain 360 and the second drain 370, which will be described later, and serves to store and discharge saliva to the outside of the unit chair.

The second drain 330 is preferably formed between the side of the main body 310 and the first drain 320.

Figures 3 and 4 show the operating mechanism of the second drain portion 330 of the dental unit chair according to the present invention. With reference to FIGS. 2 to 4 , a detailed description of the second drain unit 330 will be provided.

The second drain portion 330 preferably has a shape in which the cross-section in the longitudinal and width directions becomes narrower from the top to the bottom between the side portion of the main body portion 310 and the first drain portion 320. More specifically, in the direction from the outside to the inside of the cuspidor 300, the second drain part 330 and the first drain part 320 are continuously depressed, and the outer peripheral surface of the first drain part 320 A second drainage portion 320 is formed along.

It is preferable that the center of the second drainage portion 330 communicates with the second drainage channel 370. Accordingly, the upper end of the second drain 370 communicates with the second drain 330, and the lower end of the second drain 370 communicates with the cage 380.

A hinge 341 is formed at the boundary between the second drain part 330 and the first drain part 320, and a door part 340 is formed on the hinge 341.

At this time, it is preferable that the door part 340 has a shape that covers the second drain part 330. Accordingly, the door part 340 is preferably formed along the outer peripheral surface of the first drain part 320.

The door portion 340 is preferably capable of tilting in the vertical direction with respect to the hinge 341. At this time, before the door part 340 is tilted, it is preferable that the end of the door part 340 is in close contact with the side of the main body part 310.

Figure 3 shows the door portion 340 before it is tilted.

The saliva 2 first flows along the inside of the main body 310 and then passes through the door 340 to reach the second drain 330. At this time, the sensor 350 is coupled to the upper surface of the door unit 340. Accordingly, the saliva 2 is not discharged directly to the cage 380 through the second drain 330, but rather contacts the sensor 350 through the door 340 for a sufficient period of time before being released into the cage 380. 2 This is to form a structure that is discharged through the drain part 330. This has the effect of improving the detection accuracy of the sensor 350.

The sensor 350 is preferably a pollution measurement sensor. In addition, it is preferable that the pollution measurement sensor is, for example, a turbidity sensor. The turbidity sensor can use a known turbidity sensor sold commercially. At this time, the turbidity sensor measures the first turbidity when first contacting the batting fluid 2, measures the second turbidity after a preset reference time, and transmits the corresponding information to the control unit.

Additionally, the control unit calculates the difference between the second turbidity and the first turbidity, and controls the cleaning composition to be sprayed from the spray hole 311 when it is greater than a preset reference turbidity. The injection hole 311 will be described in detail later.

Additionally, when the control unit receives information about the first turbidity and the second turbidity, it controls the hinge 341 to tilt the door unit 340. Through this, hygiene can be improved by discharging the saliva 2 that may remain on the upper surface of the door 340.

Figure 4 shows the door portion 340 after it is tilted.

The saliva 2 is moved to the cage 380 through the second drainage channel 370. Accordingly, the main hitting fluid 2 is discharged through the first drainage channel 360, and the remaining hitting fluid 2 is discharged through the second drainage channel 370. Through this, hygiene can be improved by minimizing the remaining saliva 2 in the main body 310.

A plurality of injection holes 311 are formed on the side of the main body 310. Additionally, the spray hole 311 communicates with the spray passage 312, and the spray passage 312 communicates with the cleaning composition storage unit (not shown). Accordingly, the cleaning composition is sprayed into the main body 310 through the spray hole 311. As described above, the control unit calculates the difference between the second turbidity and the first turbidity, and controls the cleaning composition to be sprayed from the spray hole 311 if it is greater than a preset reference turbidity.

Through this, the cleaning composition flows along the inside of the main body 310, and the remaining saliva 2 can be cleaned to improve hygiene.

The cleaning composition achieves excellent cleaning and antibacterial effects while containing plant extracts. In particular, by using ingredients derived from plant extracts, there are no problems such as respiratory irritation due to scattering or volatilization of the composition, and it has the advantage of being harmless to the human body as there is no cytotoxicity.

The cleaning composition includes iris extract; It contains lime extract and artemisia extract. If it is within the above range, it shows excellent cleaning and antibacterial activity.

The mixing composition of each extract is preferably 10 to 50 parts by weight of lime extract and 1 to 10 parts by weight of artemisia extract based on 100 parts by weight of iris extract. When within the above range, a synergistic effect on cleaning and antibacterial activity can be achieved by mixing each extract.

More preferably, the cleaning composition includes 10 to 50 parts by weight of lime extract based on 100 parts by weight of iris extract; 1 to 10 parts by weight of mugwort extract; It contains 1 to 10 parts by weight of amaranth extract and 10 to 50 parts by weight of water parsley extract. In the case within the above range, the synergistic activity due to the interaction of each extract can produce the effect of greatly increasing the antibacterial activity as well as the cleaning power. Accordingly, excellent effects can be achieved with a smaller amount, and a certain amount of the cleaning composition can be used for a long period of time. In addition, it has the advantage of being harmless to the human body due to its low cytotoxicity and no respiratory irritation caused by flying dust.

The LED unit 390 is preferably coupled along the outside of the main body 310.

The LED unit 390 is preferably linked to the control unit. As described above, the control unit calculates the difference between the second turbidity and the first turbidity, and when the turbidity is higher than a preset standard turbidity, the control unit turns on the LED unit 390. Control as much as possible. Through this, it serves to visually warn the user that there is a hygiene problem in the main body 310, and automatically cleans the salivary fluid (2) using the cleaning composition, while also allowing the user to manually Hygiene can be improved by performing cleaning operations.

The water supply unit 400 is a place where water (1) is sprayed. Not only does the patient use a cup to receive the water (1) sprayed to clean the oral cavity, but the control unit also sprays water (1) at preset intervals. By controlling the water supply unit 400 to spray, the remaining saliva (2) can be minimized. Through this, hygiene can be improved.

[Preparation example: Preparation of cleaning composition]

In order to evaluate the cleaning power and antibacterial properties based on a composition derived from plant extracts, the following plant extracts were prepared, and in order to confirm the synergistic effect of mixing each extract, they were mixed in the composition shown in [Table 1] below to form a mixed composition. was manufactured.

1. Preparation of calamus extract

Calamus extract (AE) was prepared by pulverizing washed and dried calamus and extracting it with hot water.

2. Preparation of other extracts

Lime extract (BE) in the same manner as AE; Artemisia extract (CE); Amaranth extract (DE) and water parsley extract (EE) were prepared.

3. Preparation of mixed extract

Mixed extracts M1 to M10 were prepared by mixing the AE to EE according to the composition shown in Table 1 below.

[Experimental example: Activity evaluation of composition]

1. Evaluation of cleaning power

Plaque and plaque colorants were used to immerse the cuspidor surface sample for 4 hours, and the cleaning power of the cuspidor surface sample before and after cleaning was evaluated using AE and M1 to M10. The cleaning power was evaluated by comparing the area before and after washing using each composition ((area before washing - area after washing)/area before washing).

For objective evaluation, an example using purified water was set as the control group, and for objective comparative evaluation, the results of the control group were fixed at an index of 1 and compared with the results of the control group, evaluated with an index of 1 to 10. The higher the number, the more effective the index is.

2. Evaluation of antibacterial power

To determine the antibacterial activity against S. mutans, AE and M1 to M10 were added to BHI liquid medium (Brain-Heart Infusion broth: 3.7%), respectively, and then inoculated with S. mutans to maintain a temperature of 35 to 37°C. After culturing in a thermostat for 24 hours, the effect on S. mutans growth inhibition was measured. The inhibitory effect was expressed as a percentage compared to the control group treated with only purified water without adding the cleaning composition, and the lower the value, the better the effect.

Con A.E. M1 M2 M3 M4 M5 M6 M7 M8 M9 M10 Cleansing power One 2 2 4 5 4 2 4 8 7 7 4 Antibacterial power 100 92 95 74 77 70 89 72 55 61 57 76

(Unit: index, %)

Referring to [Table 2] above, it can be seen that the cleaning power and antibacterial activity increase when using AE. In addition, in the case of a mixed composition, it can be confirmed that the cleaning power and antibacterial activity are higher due to synergistic activity due to interaction in the case of M2 to M4. Therefore, when within the above range, superior cleaning power and antibacterial effect can be achieved with a smaller amount.

Meanwhile, additional synergistic activity can be observed in the case of M7 and M9. It can be seen that not only the cleaning effect but also the effect of inhibiting the activity of S. mutans is additionally increased. Therefore, when using the above range, it is possible to exhibit excellent cleaning effect and antibacterial activity while using a smaller amount for a long period of time.

The cleaning composition may be sprayed according to a predetermined standard through a plurality of spray holes formed on the side of the main body of the cuspidor. For example, if the contamination level of the cuspidor is above a certain range through a sensor that measures the contamination level, the cleaning composition may be sprayed at a certain concentration.

A cleaning composition according to another embodiment of the present invention is for use in a dental unit chair including a cuspidor for measuring the degree of contamination and a ventilation means. In this case, the composition can be used to prevent contamination of the cuspidor unit chair and ultimately increase the lifespan of dental equipment while reducing hygiene and the risk of secondary infection to patients.

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements made by those skilled in the art using the basic concept of the present invention defined in the following claims are also possible. falls within the scope of rights.
