Description

[Detailed Description of the Invention] The present invention relates to an anesthesia device for a dental treatment device, and particularly to an anesthesia device suitable for simplifying handling.

Generally, some patients who require dental treatment have extremely sensitive nerves, and when treating such patients, it is customary to administer anesthesia using laughing gas or the like.

Conventionally, this type of anesthesia device has become able to be transported independently from the dental treatment equipment placed around the patient chair, and when anesthesia is required, it can be transported close to the patient chair. He used the following method. For this reason, it is not easy to handle, and since there are many treatment devices placed around the patient chair, it is difficult to take up a large amount of space, which can sometimes get in the way of treatment. I couldn't do it. In addition, conventional anesthesia masks do not have a means to secure them to the patient's nose, so the patient has to hold the mask himself, but when the anesthesia takes effect, the mask slips and causes gas leaks. I was also afraid.

In view of this, the present invention was devised to solve these conventional problems, and its purpose is to provide anesthesia for dental treatment equipment that is easy to handle and does not have the risk of the mask coming off the patient's nose. We are in the process of providing equipment.

In other words, the present invention includes: an elastic retention band whose proximal end is attached to a predetermined position on a patient chair; a mask provided at the tip of the retention band and held in pressure contact with the patient's nose by the elastic force of the retention band; The mask includes a tube connected to the mask, and a connection port provided at a predetermined position of the patient chair and to which the tip of the tube is removably connected, and the pipe from the gas cylinder is passed through the inside of the patient chair to the connection port. This is intended to facilitate ease of handling and prevent the mask from coming off the patient's nose.

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

In FIG. 1, reference numeral 1 denotes a patient chair, and a head rest 3 whose position can be adjusted up and down is attached to the center of the upper end of a back plate 2 of this chair. A groove-shaped locking portion 4 is provided on the back side of the headrest 3, and a locking piece 6 at the base end of the holding band 5 is inserted and locked into the groove-shaped locking portion 4 from the upper end side. It's summery.

The retaining band 5 is formed by bending a band-shaped spring material as shown in FIG. 2, and as shown in FIG. It's starting to come. The tip of the retention band 5 is attached to the nose of the patient 7.
A mask 8 is attached which is held under pressure by the elastic force of. As shown in the figure, a tube 9 for supplying laughing gas and a tube 10 for exhaust are pulled out from the mask 8, and both tubes 9, 1
0 are connected to connecting tools 11, respectively.

On the other hand, a connection port 12 having a built-in valve (not shown) is installed on the back side of the back plate 2 of the patient chair 1, as shown in FIG. are designed to be removably connected. The valve built into the connection port 12 opens when the connection tool 11 is attached to the connection port 12, allowing communication between the two, and when the connection tool 11 is removed from the connection port 12, the valve is opened at the open end of the connection port 12. is now closed.

A tube 14 pulled out from a gas cylinder 13 is connected to the connection port 12 through the inside of the patient chair 1, as shown in FIG. 15 is provided to adjust the amount of gas supplied to the patient 7.

Next, the operation of the above embodiment will be explained.

During treatment that does not require anesthesia, the retaining band 5, mask 8, and tubes 9, 10 shown in FIG. 2 are removed from the patient chair 1 side. At this time, since the tube 14 from the gas cylinder 13 is connected to the connection port 12 through the inside of the patient chair 1, it does not interfere with normal medical treatment at all.

For treatment requiring anesthesia, first place the mask 8 on the nose of the patient 7, and insert and lock the locking piece 6 at the base end of the holding band 5 into the groove-shaped locking portion 4 on the back of the headrest 3 from its upper end side. do. Then, the mask 8 is held in pressure contact with the nose of the patient 7 due to the elastic force of the holding band 5, and there is no risk of it coming off.

Once the mask 8 is held in this manner, the connecting device 11 is connected to the connecting port 12 to supply laughing gas from the gas cylinder 13 to the patient 7. At this time, since the mask 8 does not need to be held by the patient 7 himself, there is no burden on the patient 7, and there is no fear that the mask 8 will come off from the patient's 7 nose.

In the above embodiment, a case has been described in which the retaining band 5 is attached to the headrest 3 by inserting the locking piece 6 of the retaining band 5 into the groove-shaped locking portion 4 of the headrest 3, but the present invention is not limited to this. Other known simple attachment/detachment mechanisms may be used, or the retention band 5 may be tilted toward the back side of the headrest 3 with its base end as an axis. Alternatively, the base end of the holding band 5 may be attached to another member, and this member may be hooked onto the shoulder of the backrest 2, for example.

Furthermore, in the embodiment described above, the case where the tube 14 from the gas cylinder 13 is passed through the inside of the patient chair 1 has been described. Of course, this also includes the case where it is placed along the surface of the object.

As explained above, according to the present invention, it is extremely easy to handle, there is no risk of the mass shifting or coming off from the patient's nose, and it does not interfere with normal treatment when not in use. Effects can be obtained.
