Definitions

  • the present invention relates to a mouth cleaning device for improving oral hygiene by flowing a minute current in a mouth.
  • a conventional mouth cleaning device an electric toothbrush or an ion toothbrush has been known.
  • the conventional mouth cleaning device removes plaque from teeth by flowing a minute current in a mouth, thereby enhancing cleaning effect of brushing, metabolism of oral tissues or blood flow.
  • Japanese Patent No. 2560162 describes therein a toothbrush including a head portion where bristles are arranged and a handle portion where a battery is accommodated, wherein an electrode connected with one pole of the battery is arranged on a part of a surface of the handle portion, whereas an electrode connected with the other pole of the battery is arranged on the head portion.
  • the present invention provides a mouth cleaning device that is efficient in massaging gum tissues.
  • a mouth cleaning device including: a head portion provided with bristles and an electrode and a handle portion provided with an electrode, wherein when an electric circuit is formed from one electrode to the other electrode via a human body by application of a voltage to the electrodes, a pulse current having a frequency of about 4000 Hz to about 15000 Hz flows therein.
  • the pulse current has a frequency of about 9090 Hz.
  • the present invention in which the pulse current having the frequency of about 4000 Hz to about 15000 Hz is made to flow is efficient in stimulating gum tissues and improving gum health.
  • FIG. 1 shows a block circuit diagram of an exemplary embodiment of the present invention
  • FIG. 2 is a cross sectional view of an exemplary toothbrush of the present invention
  • FIG. 3 illustrates an explanatory diagram for explaining exemplary variations in hemoglobin oxygen saturation of the embodiment of the present invention to.
  • FIG. 4 provides an explanatory diagram for explaining variations in an exemplary BOP (Bleeding On Probing) improvement rate of the embodiment of the present invention.
  • FIG. 2 there are illustrated a head portion 1 formed by arranging bristles 10 on one end side of a shaft 11 and a handle portion 2 accommodating therein a power source (e.g., battery or the like) 20 .
  • the handle portion 2 includes therein a driving shaft 21 having one end connected with the head portion 1 , an actuator 22 for moving the driving shaft 21 in an axial reciprocating motion or the like, and a circuit board 24 .
  • the handle portion 2 has an electrode 23 on an outer surface thereof, and the head portion 1 has an electrode 13 near roots of the bristles 10 .
  • the electrode 23 is connected with the positive pole of the battery 20 via an output resistor Ro 1 and a boosting circuit 3 mounted on the circuit board 24 .
  • the electrode 13 of the head portion 1 is connected with the grounded negative pole of the battery 20 via a conduction plate 12 installed inside the shaft 11 , the driving shaft 21 , and the circuit board 24 (i.e., an output resistor RO 2 , a current limit transistor TRa and limit resistor Rlim 2 mounted thereon).
  • the circuit board 24 has a current limit circuit 4 shown in FIG. 1 , in addition to the boosting circuit 3 .
  • the current limit circuit 4 which is formed of the control resistor Rlim 1 , the current limit transistor TRa and a limit resistor Rlim 2 , generates a constant base current from a reference DC voltage V R (current limit control DC voltage) via the control resistor Rlim 1 , and limits a collector current that can flow through the current limit transistor TRa.
  • the control resistor Rlim 1 serves to adjust the reference DC voltage V R , and can variably adjust a current limit when it is configured as a variable resistor, according to individual differences in a resistance of a human body, individual differences in reaction to a current and the like. It is preferable that the maximum value of the limited current which can flow through the human body is lower than or equal to about 300 ⁇ A.
  • the boosting circuit 3 boosts a battery voltage V B and generates a voltage V h (V h >V B ) under the control of a boost control circuit 30 .
  • the current flows from an output resistor Ro 1 to the current limit transistor TRa via the electrode 23 , the human body, the electrode 13 , the conduction plate 12 , the driving shaft 21 and an output resistor Ro 2 .
  • the current is limited to, e.g., about 100 ⁇ A, by the aforementioned base current. Therefore, even when the resistance of the human body is low, the current greater than or equal to about 100 ⁇ A does not flow and, also, an surge current can be suppressed.
  • a transistor TRb which temporarily blocking a current by reducing a base potential of the pulsed current limit transistor TRa to zero at regular intervals so that the current can flow through the human body.
  • FIG. 3 shows variations in hemoglobin oxygen saturation obtained when a pulsed current, a DC current, and no current are made to flow, wherein the saturation values are normalized with respect to the value obtained when no current is made to flow.
  • the hemoglobin oxygen saturation indicates a combination ratio between oxygen and hemoglobin in red blood cells flowing through gum blood vessels. Since the oxygen sufficiency in tissues can be monitored by measuring the hemoglobin oxygen saturation, it serves as an indicator representing a state of inflammation of gums. When the state of gum health is poor due to the inflammation of gums or the like, oxygen supply cannot meet oxygen demand and, accordingly, oxygen becomes insufficient (low hemoglobin oxygen saturation).
  • the saturation is higher when the DC current is made to flow than when no current is made to flow.
  • the saturation becomes further higher when a pulsed current of about 4545 Hz is made to flow, and highest when a pulse current of 9090 Hz is made to flow.
  • the saturation is smaller when a pulsed current of 15000 Hz is made to flow than when the pulsed current of 9090 Hz is made to flow.
  • FIG. 4 illustrates variations in BOP (Bleeding On Probing) when the pulsed current of 4545 Hz is made to flow for one month during tooth brushing and when no current is made to flow.
  • BOP Beleeding On Probing
  • the electrode 13 is a negative electrode to which a single pole pulsed current is supplied to prevent elution of an electrode metal.
  • teeth or gums serve as a cathode.
  • a metal of the anode is eluted, and the eluted metal is deposited on the teeth or the gums serving as the anode.
  • the anode can be made of a material other than a metal or a material that is not eluted. If such a material is employed as the electrode 13 , the electrode 13 can be positively biased or AC-biased.
  • the actuator 22 (or another driving unit) can be omitted.
