[Prior art]
FIG. 2 is a view for explaining an example of a dental treatment unit provided with an extra-oral vacuum device and an intra-oral vacuum device. In the figure, reference numeral 10 denotes a dental treatment unit, and the unit 10 comprises a treatment chair 1, a work table, 2, an instrument lamp 5, an instrument holder 5, a foot switch 6, an instrument holder 7 for assistants, etc., and various instruments 8 used in dental treatment As is well known, in a dental treatment, a patient sits on a chair 1 and fixes his / her head on an abutment 9 to receive the treatment. During the treatment, the surgeon moves the treatment chair 1 up and down, starts up, tilts, etc., so that the patient can be treated in a posture that facilitates treatment.
[0003]
The assistant instrument holder 7 is provided with an intraoral vacuum hose 11, a spray syringe 12, a saliva discharge tube 13, and the like. During treatment, the assistant operates a push button or the like on an operation panel. These instruments are driven to suck and discharge dirt, waste liquid, saliva, and the like generated in the oral cavity of the patient, or to spray the spray or the like into the oral cavity to clean the oral cavity. 14 is an intake port, 15 is a vacuum hose, 16 is an intake arm supporting the intake port 14 and the vacuum hose 15, and the intake port 14, the vacuum hose 15 and the intake arm 16 constitute an extraoral vacuum device. The aforementioned arm 17 for the instrument holder for the assistant is, for example, rotatably and integrally attached to the arm 16 for intake. As is well known, during the dental treatment, the suction port 14 is moved to the vicinity of the patient's mouth, and the contaminated air discharged from the patient's mouth is suctioned from the suction port 14, and the vacuum hose 15, the suction arm 16 (pipe), The water is sucked and discharged to a central vacuum unit through a plumbing box (not shown) buried under the floor through a water supply / drain box 17.

FIG. 3 is a schematic diagram of a main part for explaining an example of a tooth surface cleaning / cleaning device. In the figure, reference numeral 20 denotes a handpiece body, 21 denotes a nozzle, and 22 denotes a powder provided on the handpiece body 20 The storage part 23 is a hose for supplying air and water, and the nozzle part 21 is composed of a nozzle 21a for injecting air (A) mixed with powder, and an outer cylinder 21b concentric with the nozzle 21a, Water (W) is injected from a gap between the nozzle 21a and the outer cylinder 21b. By operating the valve switching button 20a, for example, powder, air and water are mixed and ejected from a nozzle, and the powder is applied to the tooth surface to remove and remove plaque, tar, tartar and the like on the tooth surface. Later, water is sprayed on the tooth surface to wash the tooth surface, and after cleaning, only air is injected to prevent clogging of the nozzle due to adhesion and solidification of powder.
[0005]
[Problems to be solved by the invention]
As described above, in the dental treatment, during the dental treatment, for example, tooth cutting powder or the like is generated, and at the time of cleaning the tooth surface, powder for tooth surface cleaning is sprayed. The tooth cleaning powder may enter the patient's respiratory tract during tooth treatment or tooth cleaning.
[0006]
The present invention has been made in view of the above circumstances, and in particular, to prevent tooth cutting powder generated during dental treatment and powder sprayed during tooth surface cleaning from entering the respiratory organ of a patient. It was done for the purpose.
[0007]
[Means for Solving the Problems]
The present invention relates to a respiratory protection device for preventing tooth cutting powder or the like generated during dental treatment from entering a respiratory organ of a patient, wherein the respiratory protection device is integrated with an extraoral vacuum hose. It comprises a movable air hose and an air curtain forming member detachably provided at the distal end of the air hose. During dental treatment, the air curtain forming member is moved to the front of the nasal cavity of the patient, An air curtain is formed at the front of the nasal cavity to prevent tooth cuttings from entering the patient's respiratory tract.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a schematic diagram of a main part for explaining an embodiment in which dust generated during an operation such as tooth cutting by an operator (doctor) is prevented from entering a respiratory organ of a patient. In the figure, 8 is an instrument used by an operator in dental treatment, for example, an air turbine or a micro engine used for cutting teeth, etc., 14 is an intake port of an extraoral vacuum device, and 15 is an extraoral vacuum. In the present invention, an air hose 30 is integrally attached along the extra-oral vacuum hose 15 so as to move together with the extra-oral vacuum hose 15. An air curtain forming member (rectifying adapter) 31 having an elongated opening is detachably attached to the distal end of the air hose 30 so as to inject air in a plane, that is, to form an air curtain. I have. Therefore, at the time of dental treatment, the air curtain forming member 31 moves so as to be located above the front surface of the nasal cavity of the patient 40, and the air is jetted from the air curtain forming member 31. When an air curtain is formed on the front surface of the nasal cavity of the patient 40, for example, tooth cutting powder generated during dental treatment , or tooth cleaning powder sprayed at the time of cleaning and cleaning the tooth surface, etc., is injected into the patient's nares. There is no intrusion and the patient's respiratory tract can be protected.
Furthermore, when the air flow forming the air curtain is sucked into the extraoral vacuum hose 15, tooth cutting powder generated by dental treatment , or tooth surface cleaning powder or the like which is sprayed at the time of tooth surface cleaning and cleaning is used. The air is sucked into the extra-oral vacuum hose 15 together with the air flow, so that dust can be more effectively prevented from entering the respiratory organ of the patient.
[0011]
【The invention's effect】
As is apparent from the above description, according to the present invention, it is possible to prevent tooth cutting powder generated during dental treatment or tooth cleaning powder sprayed during tooth cleaning from entering the patient's respiratory system. It can be effectively prevented. Furthermore, air curtain forming member which may come into direct contact with patients, so and is detachably installed, for each patient, it is possible to use those subjected to sterilization treatment such as an autoclave, there is also a hygienic .
