が強く望まれてきたのである。(b) Conventional technology and problems Usually when a dentist treats a patient's teeth, the dentist places his or her face close to the patient's mouth. The patient was in a treatment environment where he inhaled harmful molecules such as saliva, and was wearing a mask over his mouth to block out the harmful molecules emitted by the patient. However, to the best of the present inventor's knowledge, there is currently no mask that can completely block harmful molecules such as air bacteria and saliva, and for this reason, especially when a long-term tooth cutting treatment is performed, A large amount of metal cutting dust, saliva, and airborne bacteria are generated, creating an unfavorable treatment environment, and those undergoing treatment are constantly exposed to the risk of occupational diseases such as bronchitis. Still, using current masks for long periods of time tends to cause respiratory fatigue, and masks also create a feeling of mental pressure on patients, so it is desirable for patients to be in a mentally relaxed atmosphere. This is a disadvantage that is favorable for dental treatment. One of the latest treatments is called laughing gas sedation, in which a mask-like device is placed over the patient's nose and laughing gas, a gas that makes the patient feel relaxed, is injected into the patient's nose. This is a treatment method that allows dental treatment to be performed while making the patient feel relaxed. However, if some of this laughing gas leaks out of the patient's nose during treatment, there is a high possibility that the dentist will inhale this gas, making the doctor and dental hygienist feel too relaxed and nervous. This creates an unfavorable condition when treating missing teeth. Therefore, there has been a strong desire for the emergence of a technology that can solve the problems described above.

The air flow generator 1 can draw air A into laminar flow, maintain the laminar flow state within a distance range of 50 to 60 degrees, and have a velocity of 1 to 1.25 degrees during this time.
Any laminar flow A' that can be made 1n/sec is sufficient. Further, the shape of the laminar flow A' can be freely selected in terms of width and thickness depending on the shape of the outlet of the air flow generator 1, and preferably, the width is about 120+u+the thickness is about t50 mm. The guide plate 2 is made of a lightweight mild steel plate or the like, and can freely change the direction of the laminar flow A'.
It is integrally fixed to the air flow generator 1. Reference numeral 6 denotes a connecting punch, which is fixed to the air flow generator 1, and the end 5 of the connecting punch 6 is connected to a surgical light so that the air flow generator 1 can be placed near the patient's face 4. It is fixed to the support punch 6 using a fastener.

ない速度とするものである。The air mask forming method according to the first invention is carried out using the apparatus as described above. Next, to explain this in detail, first, in FIGS. 1 and 2, air A' is sucked into the air flow generator 1, becomes laminar flow A', and flows out from the air flow generator 1. However, the guide plate 2 allows the air to flow laterally to the patient's face 4 above the vicinity of the oral cavity 10, thereby forming an "air mask." Therefore, during dental treatment, harmful molecules 11 such as air bacteria, saliva, and cutting dust discharged from the patient's oral cavity 10 are blocked by the laminar flow A' forming the air mask, and are directed upwards from the laminar flow A'. It will not spread or scatter. That is, the laminar flow A' has a width of 1 near the oral cavity 10.
20 pieces, 6f3mm thick and 1~1.25m
Since the air flows at a constant speed of /sec and completely forms an "air mask," all harmful molecules discharged from the oral cavity 10 are blocked by this laminar flow A' and do not break through the laminar flow A'. They will flow together in the flow direction of the laminar flow A'. Of course, the speed of the laminar flow A' is such that it does not cause discomfort to the patient.

Note that, hereinafter, parts similar to those in the first invention are indicated by the same reference numerals, and redundant explanation will be omitted. Reference numeral 12 denotes an air flow inhaler, which inhales laminar flow A'. That is, the air flow generator 1 is placed on the primary side, and the laminar flow A' flowing out from the air flow generator 1 is inhaled on the secondary side beyond the patient's face 4.

とになる。The method for forming an air mask according to the second invention is carried out using the apparatus as described above. Next, to explain this in detail, first, in FIGS. 6 and 4, the laminar flow A' that flows out from the air flow generator 1 and passes near the patient's oral cavity continues to flow while forming an "air mask". The air is sucked in through the suction port 16 of the air flow inhaler 12 located on the secondary side. Therefore, as shown in FIG. 6, in dental treatment using the laughing gas mask 17, even if there is some excess laughing gas 18 leaking from the laughing gas mask 17, it will flow laminarly with the harmful molecules 11. The laughing gas 24 and the harmful molecules 11 are not directly inhaled by the person undergoing treatment because they are attracted by A' and flow further along the line and enter the suction port 16 on the secondary side. In addition, the inhaled laughing gas 18 and harmful molecules 11 are removed by a fan 16 with a filter.
It is then released to the outside in a somewhat diluted state.

にならないという効果もある。(f) As described in detail, according to the first invention, a laminar air mask is formed between the patient's face and the dentist's face, so that air is discharged from the patient's oral cavity. Harmful molecules such as bacteria, saliva and cutting dust are removed by doctors, dental hygienists, and
This has the effect of preventing other people from smoking it. Furthermore, according to the second invention, in addition to the effects of the first invention, an unbroken laminar air mask is formed between the patient's face and the dentist's face by being inhaled on the secondary side. During laughing gas treatment, dentists and others inhale this laughing gas so that any excess laughing gas that leaks out from the patient is inhaled along the laminar air mask on the secondary side. The conventional problem of not feeling tense during treatment is eliminated. Furthermore, since the "air mask" only needs to be formed near the patient's oral cavity, and the direction in which the laminar flow flows can be freely set, it does not interfere with dental treatment.
