FIG. 4 is a schematic diagram of a main part for explaining an example of a tooth surface cleaning / cleaning device. In FIG. The storage section 23 is a hose for supplying air and water, and the nozzle section 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 the nozzle from clogging due to powder adhesion and solidification.
[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 invention according to claim 1 is a respiratory protection device for preventing tooth cutting powder and the like generated during dental treatment from entering a respiratory organ of a patient, wherein the respiratory protection device includes an extraoral vacuum hose and It comprises an air hose that can be moved integrally, and an air curtain forming member that is detachably provided at the tip of the air hose, and moves the air curtain forming member to the front of the nasal cavity of a patient during dental treatment. An air curtain is formed at the front of the patient's nasal cavity to prevent tooth cutting powder from entering the patient's respiratory tract.
[0008]
The invention according to claim 2 is a respiratory organ protection device for preventing powder from entering into a patient's respiratory organ when cleaning powder by injecting powder for tooth surface cleaning onto the tooth surface, The respiratory protection device is characterized in that it is a cover member that is detachably attached to the distal end of the intraoral vacuum hose and covers the front surface of the nasal cavity of the patient.
[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 extraoral vacuum hose 15 so as to move together with the extraoral 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 the air curtain is formed on the front surface of the nasal cavity of the patient 40, for example, tooth cutting powder or the like generated during dental treatment does not enter the nares of the patient, and the respiratory organ of the patient can be protected. .
Further, when the air flow forming the air curtain is sucked into the extra-oral vacuum hose 15, tooth cutting powder and the like generated by the dental treatment are sucked into the extra-oral vacuum hose 15 together with the air flow, which is more effective. Dust can be prevented from entering the respiratory tract of the patient.
[0010]
FIG. 2 is a schematic view of an essential part for explaining an embodiment in a case where a tooth cleaning powder ejected from a tooth cleaning device is prevented from entering a respiratory organ of a patient during tooth cleaning. In the configuration diagram, in the figure, reference numeral 20 denotes a tooth surface cleaning device shown in FIG. 4 as an example. As described above, the assistant sprays tooth surface cleaning powder from the tooth surface cleaning device 20 to clean the tooth surface. When cleaning is performed, the sprayed powder may enter the nostrils of the patient. Reference numeral 11 denotes an intra-oral vacuum hose similar to the intra-oral vacuum hose 11 shown in FIG. 3. 50 is provided detachably. When the assistant cleans the patient's tooth surface using the tooth surface cleaning device 20, the assistant covers the patient's nostril with the cover member 50 attached to the intraoral vacuum hose 11, so that the tooth surface cleaning device 20 can be cleaned. There is no possibility that the powder for cleaning the tooth flank sprayed from the patient enters the patient's respiratory tract.

【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, since the air curtain forming member and the dust cover which may directly touch the patient are detachable, it is possible to use a sterilized autoclave or the like for each patient, so that sanitary treatment can be performed. But also.
