Description

  The present invention relates to a spit-on device in a dental treatment unit, and more particularly, to a cup-type gargle water supply spit-on device, in the case where a cleaning person's hand crosses the upper part of the cup-holding portion during cleaning of the cup-setting portion. In addition, the present invention relates to a spit-on device in which a cup sensor mistakes the operator's hand for a cup so as not to inject gargle water, and furthermore, the amount of gargle water supplied to the cup can be easily adjusted.

  FIG. 3 is a schematic overall configuration diagram for explaining an example of a dental treatment unit including a spit device to which the present invention is applied. The dental treatment unit includes a treatment chair 1, a work table 2, and an operator (doctor). Instrument holder 3, surgeon instrument 4, instrument hose 5, assistant instrument holder 6, etc. The instrument holder 3 includes various instruments used in dental treatment. 4 is housed, and as is well known, during dental treatment, the patient is moved down, tilted, tilted, etc. to make the patient easy to treat, and the instrument 4 is attached to the instrument 4 from the instrument holder 3. Pull out and treat.

  The instrument holder 6 for assistant is provided with a syringe, a vacuum tube, a saliva discharge tube 7 and the like, and the assistant cleans the inside of the patient's oral cavity at the time of treatment. The liquid and saliva are sucked and discharged. The assistant instrument holder 6 is a stand-alone type, but as shown in the figure, there is also an assistant instrument holder 6 fixed to a fixing member, for example, a Spitton water supply / drainage box through an arm 8.

  In addition, the dental treatment unit comprises a spitton device 10, and the patient gargles in the oral cavity using the spitone device 10 prior to or during the dental treatment, but as shown, the spiton device. 10 is composed of a water supply / drainage box 11, a gargle water injection pipe 12 (see FIG. 1), a cover member 13 covering the gargle water injection pipe 12, that is, gargle water is poured into the cup 20 from the gargle water injection pipe 12. In the case of a cup-type gargle method that gargles with water in the cup 20, a non-contact cup sensor such as an ultrasonic sensor or an optical sensor is provided in the vicinity of the gargle water injection port 12a of the gargle water injection pipe 12. When the cup is placed on the cup holder, the cup sensor detects the presence of the cup, and a predetermined amount (the height of the gargle water in the cup becomes a predetermined height) in the cup. Gargle water quantity) to have so as to automatically supply.

  As described above, in the case of the cup-type gargle method, the presence of the cup is always detected by the cup sensor, and when the cup is detected, the amount of water in the cup reaches a predetermined height (set height) position. Since the gargle water is automatically ejected from the gargle water supply pipe 12, when the cup holder is to be cleaned, the cup sensor is not turned on unless the dental treatment unit is turned off. There was a problem that a hand was mistakenly detected as a cup and gargle water was jetted.

Further, when the amount of gargle water supplied to the cup 20 is to be adjusted, the water surface in the cup (the height of the water in the cup) is usually detected from the reflection of ultrasonic waves or light emitted from the cup sensor. For this reason, the intensity of irradiation (emission) of ultrasonic waves or light is adjusted, or the sensitivity of a sensor for detecting the reflection thereof is adjusted. Adjustment of the reflection detection sensitivity involves adjustment of an electrical component (for example, a variable resistor). However, the electrical parts do not like water, and therefore, the electrical parts for adjusting the amount of water are arranged in a sealed space covered with screws and the like. The adjustment work was difficult. For example, a gargle water injection pipe 12 is constituted by a base 13 ₁ and the cover member 13 _2, and the lid member 13 ₂ from the base 13 ₁ by screws or the like to attach detachably, during adjustment, the cover member 13 ₂ Removing, although to adjust the adjusting member is attached to the base 13 ₁ (electrical component), removal of the lid member, with the mounting operation, water adjustment was difficult.

  The present invention has been made in view of the above circumstances, and in the cup-type gargle water supply spittoon device, the main staff of the dental treatment unit in which the spittoon device is incorporated each time a cleaning person cleans the cup holder. Cleaning work can be done without going off the power supply, and furthermore, when adjusting the amount of gargle water supplied to the cup, adjustment can be made without removing the waterproof cover member The present invention has been made for the purpose of providing a spitton device having a water amount adjusting function.

The invention of claim 1 has a cup holder, and a gargle water injection pipe that supplies gargle water to the cup placed on the cup holder, and supplies gargle water to the cup from the gargle water injection pipe. In the dental spitton device, the light source that illuminates the cup holder, a switch that turns on and off the light source, and a cup sensor that detects that a cup has been placed in the cup holder. , by pressing the switch, the light source is changed number of blinks per unit time, the amount of gargle water supplied to the cup somewhat correspond flashing number per the unit time is set It is characterized by.

  According to a second aspect of the present invention, in the first aspect of the invention, the number of blinks per unit time of the light source is three types: large, medium, and small. Is characterized in that the number of times of blinking changes sequentially and repeatedly.

  The invention of claim 3 has a cup holder, and a gargle water injection pipe that supplies gargle water to the cup placed on the cup holder, and supplies gargle water to the cup from the gargle water injection pipe. In the dental spit device, the light source that illuminates the cup holder and a switch that turns the light source on and off are turned off by operating the switch, and when the light source is turned off The gargle water is prevented from being jetted.

The invention of claim 4 is the invention of claim 3, further comprising an electromagnetic valve provided in a water circuit communicating with the gargle water injection pipe, and a sensor for detecting a water surface in the cup , wherein the light source is turned on. When the amount of water in the cup is smaller than a set value, the sensor is activated to open the electromagnetic valve to set the amount of water in the cup to a set amount.

  The invention of claim 5 is characterized in that, in the invention of claim 4, the electromagnetic valve is closed in conjunction with turning off the light source.

  To adjust the amount of water supplied to the gargling cup, there is no need to remove the liquid-tight cover member and adjust the internal electrical parts as in the prior art, and push the push button (standby switch). Adjustment is possible just by making the adjustment work much easier. In addition, it is no longer necessary to turn off the main power supply every time when cleaning the cup holder, and the cleaning work of the cup holder becomes very easy.

FIG. 1 is an external view of a main part for explaining an embodiment of a spit device according to the present invention, FIG. 2 is a diagram for explaining an operation, in which 11 is a water supply / drainage box, 12 is a gargle water injection pipe, gargle water injection tube 12 is covered by a cover member 13 made of a base 13 ₁ and the cover member 13 ₂ which, the lid member 13 ₂ is to be removably attached by screws or the like to the base 13 ₁ It has become. The upper end of the gargle water injection pipe 12 has a gargle water injection port 12 a, and the lower part is connected to an electromagnetic valve provided in the water supply / drainage box 11.

The base 13 ₁ of the upper cover member 13 for covering the gargle water injection pipe 12, a light source (e.g., blue light) 15 and a switch 16 for controlling turning on and off the light source 15, the position of the cup 20 and within the cup And a sensor (not shown) for detecting the water level. The electric circuit components such as the light source, the switch, and the sensor are provided in the gargle water injection tube cover member 13 in order to prevent gargle water sprayed from the gargle water injection port 12a from splashing and getting wet. These electrical components are attached, repaired, adjusted, etc. by removing the lid member 13 ₂ from the base 13 ₁ .

Light source 15 is illuminated by turning on the main power supply of the dental care unit (ON) (see S ₁ in FIG. 2), the sensor is turned on (cup detectable state) (see S ₂ in FIG. 2). In this state (state A in FIG. 2: water supply possible state = lamp lit state), when the cup 20 is placed on the cup holder, the sensor works to detect that the cup has been placed and water enters the cup. If not, or if the amount of water is small, opens the water supply valve in the water supply and drainage box 11 (solenoid valve), gargle water is injected into the cup 20 from the gargle water injection port 12a (see S ₃ in FIG. 2) . Each time the patient gargles during dental treatment (every time the water in the cup 20 is used), the sensor is activated each time the cup 20 is returned to the cup holder after gargle, and the presence of the cup 20 is detected. When the amount of water in 20 is small, gargle water is detected in the cup 20 until the set (adjusted) amount (water level) is reached, and a predetermined amount of water is always stored in the cup 20 to gargle. I'm getting ready.

  Conventionally, when the cup holder is cleaned in the above-described state, the sensor is removed when the operator reaches for the cup holder by removing the cup 20 and wiping the cup holder with a rag or the like. In response to the worker's hand (detecting the worker's hand mistakenly as a cup), there was a problem that gargle water was jetted from the gargle water jet 12a.

The present invention can solve the above-described problems. In particular, when cleaning the cup holder, the cup sensor function is disabled, and the operator can easily determine that the cup sensor does not work. When cleaning the cup, water is prevented from being jetted from the gargle water jet 12a. That is, in FIG. 1, and presses the switch 16 (see S ₄ in FIG. 2), a light source (e.g., blue light) 15 is turned off (OFF), dental care unit, and the standby state shown in B in FIG. 2 Become. At this time, that is, when the light source 15 is turned off, even if the cleaner's hand crosses over the cup holder, the gargle water is not jetted.

Furthermore, conventionally, when adjusting the amount of gargle water supplied to the cup 20, remove the cover member 13 _{and second} gargle water supply pipe 12, the adjustment member being attached to the base 13 ₁ (e.g., a variable resistor Although out as to adjust the resistance value), each of the adjustment must remove the cover member 13 _2, adjustment work is troublesome.

As described above, the switch 16 has a function of stopping the sensor function, but also has a function of adjusting the amount of water supplied to the cup, and is in a standby state shown in FIG. in, by pressing the switch (standby switch) 16 length (see S ₅ in FIG. 2) becomes a maintenance state shown in C of FIG. 2, the light source 15 flashes, changing number of flashes per unit time (blinking period) Thus, the amount of water supplied to the cup 20 can be adjusted.

The blinking cycle of the light source 15 changes every time the standby switch 16 is pressed, for example, changes in three stages, and the amount of water (water level) supplied to the cup 20 is low (Lo), medium (Mid), high ( into three levels Hi) is adjustable (see S ₆ in FIG. 2). Specifically, every time the standby switch 16 is pressed, the light source blinks once every 0.3 seconds (Lo setting), and when the light source is blinking in this blinking cycle, the standby switch 16 is pressed and held. or a predetermined time (e.g., 10 seconds or more) if the no-operation (see S ₆ in FIG. 2), the amount of water supplied to the cup 20 is adjusted to a low (Lo).

  Thereafter, each time the standby switch 16 is pressed, the blinking cycle of the light source changes. For example, the light source blinks twice every 0.3 seconds (Hi). In this state, the standby switch 16 is pressed for a long time or a predetermined time (for example, If no operation is performed (for 10 seconds or more), the amount of water supplied to the cup 20 is adjusted to the middle level (Mid).

Thereafter, when the standby switch 16 is further pressed, the blinking cycle of the light source is changed, for example, blinks three times every 0.3 seconds. In this state, the standby switch 16 is pressed for a long time or no operation is performed for a predetermined time or more. Thus, the amount of water supplied to the cup 20 is adjusted to high (Hi). To set the desired amount of water, press and hold the standby switch at the desired amount of water (flashing cycle), or if you do nothing for a predetermined time (for example, 10 seconds or more), set the amount of water at that time ( see S ₇ of FIG. 2).

  As described above, according to the present invention, each time the cup holder is cleaned, the dental treatment unit main power supply is turned off or on without going back and forth (conventionally, the main power supply of the dental treatment unit is mounted on the cup. It was located away from the unit, and it was difficult for the operator to move the main power supply on and off.

  Further, in order to adjust the amount of water supplied to the gargle cup, there is no need to remove the liquid-tight cover member and adjust the internal electrical parts as in the prior art. ) Can be adjusted simply by pressing, making the adjustment work much easier. The standby switch 16 is not limited to the illustrated position, and may be anywhere as long as the gargle water supply operation can be easily performed.
