Abstract

<P>PROBLEM TO BE SOLVED: To enable a full conversation with an operator in relation to both a patient with weak hearing ability and a patient with an earplug or wearing headphones by integrally or removably preparing a bone conduction loudspeaker in the headrest section of a dental care seat. <P>SOLUTION: The bone conduction loudspeaker 10 is embedded within the headrest 9 of the dental care seat 1 and the bone conduction loudspeaker 10 is actuated (vibrated), for example, by a microphone 20 removably connected to the dental care seat 1. Therefore, when the patient with weak hearing ability and the patient wearing the earplug or the headphones are treated, the operator speaks to the patients through the microphone 20 and the bone conduction loudspeaker 10, the patients can respond to the operator in a natural voice, and the operator can perform dental care with having a conversation with the patients. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention provides a dental treatment chair, more specifically, a bone conduction speaker provided integrally or detachably on the headrest portion of the dental treatment chair, for example, for a patient with weak hearing ability. It is intended to allow for sufficient conversation.

  FIG. 4 is an overall configuration diagram showing an example of a dental treatment unit to which the present invention is applied. The dental treatment unit includes a treatment chair 1, a work table 2, an operating light 3, an operating light arm 4, and an instrument holder. 5, a foot switch 6, an assistant instrument holder 7, and the like. The instrument holder 5 stores various instruments 8 used in dental treatment. The patient sits on the chair 1 and fixes his head on the headrest 9 for treatment. During treatment, the surgeon moves the treatment chair 1 up and down, tilts up, tilts, etc., and treats the patient in a posture that facilitates treatment.

  Thus, during the dental treatment, the surgeon talks with the patient, for example, explains the condition of the treatment site to the patient or explains the treatment method to the patient. If you are a weak person, the surgeon's talk may not be fully communicated to the patient.

  In addition, even people who are not hearing-impaired use earplugs or headphone stereos to reduce the unpleasant sounds generated by air turbines and the like when teeth are cut. Even in such cases, there was a problem that sufficient conversation between the surgeon and the patient could not be obtained.

  The present invention has been made in view of the above-described circumstances, and in particular, a person who is hearing-impaired or a person who wears earplugs or headphones during dental treatment so that a tooth cutting sound or the like cannot be heard. The purpose of this is to allow the surgeon to perform dental treatment while talking.

  In order to achieve the above-described object, the present invention provides a bone conduction speaker in a portion on which a patient puts his head (headrest portion) or a portion corresponding thereto in a dental treatment chair, and receives a microphone sound from an operator on the bone. It is applied to the patient's skull through a conduction speaker, and the vibration from the bone conduction speaker is transmitted to the inner ear, enabling conversation between the operator and the patient.

  It is possible to transmit the speech from the surgeon through bone conduction to a hearing-impaired patient or a patient who is prevented from hearing a tooth cutting sound with earplugs or headphones.

  In the dental treatment chair, the bone conduction speaker is provided in a portion on which the patient puts his head (headrest portion) or a portion equivalent thereto, and the hearing ability is used when the operator talks with the patient during the dental treatment. Even for patients who are weak, the headphone stereo and earplugs can be used to reduce the noise during tooth cutting, such as an uncomfortable air turbine. It communicates with the patient through a conductive speaker so that conversation with the patient is possible.

  As described above, one of the unpleasant factors for a patient visiting a dentist is a tooth cutting sound such as an air turbine. In addition, this tooth cutting sound (noise) may give fear to the patient. In order to eliminate this tooth cutting sound, it is possible to use earplugs or headphones, but this time, necessary sounds (such as conversation with the teacher) are also erased. Therefore, the present invention intends to use a bone conduction speaker and headphones in combination to eliminate noise and enable necessary conversations.

  FIG. 1 is a schematic configuration diagram of a main part (headrest portion) for explaining an embodiment of a dental treatment chair according to the present invention. In the illustrated embodiment, a bone conduction speaker 10 is provided in a headrest 9 of the dental treatment chair 1. The bone conduction speaker 10 is driven by a microphone 20 that is detachably connected to the dental treatment chair 1, for example. Therefore, when a patient with weak hearing, a patient with earplugs or headphones undergoes dental treatment, the operator can talk to the patient through the microphone 20 and the bone conduction speaker 10, and the patient can respond to the operator with his / her voice, The surgeon can perform dental treatment while talking with the patient.

  Although an example in which the bone conduction speaker 10 is embedded in the headrest 9 has been described with reference to FIG. 1, in the present invention, the bone conduction speaker 10 does not necessarily have to be embedded in the headrest portion. Alternatively, it may be attached to another member to be extended, and further, it can be detachably attached to the headrest 9, and the patient's head is placed on the bone conduction speaker 10 during dental treatment. Anything is acceptable.

  In the above, the bone conduction speaker 10 and the microphone 20 that vibrates the bone conduction speaker 10 are connected by wire. However, the bone conduction speaker 10 may be driven wirelessly by the microphone 20. Good.

  Alternatively, the bone conduction speaker 10 may be attached integrally with the earplugs or headphones, and the bone conduction speakers may be mounted on the patient's head when the earplugs or headphones are used.

  FIG. 2 is a view showing an example in which a bone conduction speaker 10 is provided on an extension member 11 extending from the headrest 9, and the bone conduction speaker 10 supports the patient's head by supporting the bone conduction speaker. Ten vibrations can be transmitted to the patient's inner ear by bone conduction.

  FIG. 3 is a schematic configuration diagram showing an example of a case where the bone conduction speaker 10 is integrally combined with the headphones 30. In this example, the bone conduction speaker 10 is attached to the headphone band 31, and the vibration of the bone conduction speaker 10 is observed. , It is transmitted to the patient's inner ear by bone conduction.

  As is clear from the above explanation, according to the present invention, the surgeon can perform dental treatment while talking to a patient with weak hearing, or a patient who has been prevented from hearing a tooth cutting sound with earplugs or headphones. It can be performed.

It is a principal part (headrest part) schematic block diagram for demonstrating one Example of the dental treatment chair by this invention. It is a figure which shows an example at the time of providing the bone conduction speaker in the extending member extended from a headrest. It is a schematic block diagram which shows an example at the time of combining a bone conduction speaker integrally with headphones. It is a whole block diagram which shows an example of the dental treatment unit to which this invention is applied.
