BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction hood of a dental dust collecting apparatus for sucking and removing contaminated air containing dust, saliva and the like generated from a patient's mouth during dental care.

[0002]

2. Description of the Related Art In dental treatment, a dust collector for sucking contaminated air including dust, saliva, etc. emitted from a patient's mouth is widely used. As shown in FIG. 11, such a device includes a hood 51 serving as a suction unit for contaminated air generated from the mouth of a patient, and a built-in filter connected to the hood 51 and a hose 52 and installed near the patient. Suction unit 55 and the suction unit 55
Are connected by a connection pipe 53, and are constituted by a blower which is a suction source of the apparatus and a main body 54 provided with a filter (both not shown). In the dust collector having such a configuration, contaminated air containing cutting dust, saliva, and the like generated at the time of tooth treatment is discharged from the vicinity of the mouth of the patient to the hood 51.
The filter in the suction unit 55 removes relatively large cutting dust and the like, and the filter of the main body 54 removes finer contaminants. The opening of the hood 51 has a diameter capable of sucking contaminated air scattered from the inside of the mouth to the outside from the outside of the mouth. In this device, the hood must be held manually, but a device including a support member such as a column for fixing the hood to the mouth of the patient when the practitioner performs treatment and suction work alone. Is also used.

[0003]

However, in dentistry, the shape and size of the hood 51 are fixed in spite of the fact that the state of generation of contaminated air varies depending on the type of treatment and the like. Has problems. First, the opening of the mouth changes depending on the position of the tooth to be treated.
Although the area to cover the mouth should be changed according to the conventional suction device, even if the contaminated air only needs to be sucked from a small area, a large hood is located at the mouth of the patient, and the caregiver's Unnecessarily obstructs the view. In addition, when anesthetizing a patient with laughing gas, it is necessary to suction the inhalation from a wider area than the mouth of the patient so that the laughing gas does not disperse in the treatment room. The hood may be too small.

[0004] In view of the above problems, the problem of the present invention is:
It is an object of the present invention to realize a dental medical dust collector capable of setting an optimal suction range according to a treatment situation.

[0005]

In order to solve the above-mentioned problems, the means taken in the dental dust collecting apparatus according to the present invention is connected to the suction source side to remove contaminated air generated during dental treatment. A hood body attached to a suction member for suctioning, a hood main body having an opening extending from a base end side toward a distal end side, and a front end side opening different from the front end side opening of the hood main body; An auxiliary hood is provided in which the base end is connected to the distal end of the main body via a locking mechanism and is connected toward the distal end or removed therefrom.

[0006] Here, it is preferable that the front opening of the auxiliary hood is larger than the front opening of the hood main body. That is, it is preferable that the auxiliary hood can be used as an extension hood of a suction portion.

Further, in the present invention, a tray-shaped receiving portion extending toward the front end side from the lower side of the front end edge of the auxiliary hood connected to the hood body. Is preferably provided.

Further, it is preferable that the inner wall surface of the hood main body is formed of a gentle continuous surface from the opening at the distal end to the opening at the proximal end.

[0009]

In the dental dust collecting apparatus according to the present invention, when the suction source is operated in a state where the hood main body is arranged at the mouth of the patient, contaminated air generated from the oral cavity of the patient during dental treatment causes the hood main body and the suction. Since it is sucked through the member, the treatment room can be prevented from being contaminated. here,
An auxiliary hood that can be freely connected to the tip of the hood body,
Since the size of the opening on the tip side is different from the size of the opening on the tip side of the hood body, it can be switched between the connected state and the detached state to adjust the range where air can be sucked arbitrarily it can. For example, by making the auxiliary hood body larger than the hood body, when treating with a patient with a small mouth open,
When air only needs to be sucked in from a narrow area, use the hood alone and use a wide range of air, such as when performing treatment with the patient's large mouth open or inhaling laughter gas without leakage. When you need to aspirate
Use with the auxiliary hood connected to the hood body. In this way, it can be used properly depending on the state of generation of the contaminated air to be sucked. In particular, if the hood body is smaller, it is necessary to suck air only from a narrow area.
Since the hood is used alone, the field of view for the patient is not unnecessarily obstructed during the treatment, and the hood is easy to use.
