Yes. Moreover, a hole 3a is formed in a portion of the mixing tube 3 where the steam pipe 1 is inserted, and a pipe collar 3b made of silicon rubber is fitted into the hole 3a. A stainless steel pipe pin 5 that penetrates the steam pipe 1 is fitted into the pipe collar 3b.

  6 is an outer cover formed of a synthetic resin, such as polypropylene, which is divided into two parts and is excellent in heat resistance and chemical resistance, and is arranged so as to cover the outer periphery of the mixing tube 3 described above. A fastening portion 6a for fixing the formed outer cover 6 is fitted and formed into a cylindrical shape with a fixing packing 6b made of foamed silicon rubber provided on the inner peripheral surface of the base end portion. The outer periphery of the mixing tube 3 is fixed.

  A steam outlet 6c is formed on the outer periphery of the front end portion of the outer cover 6, a step portion 6d is formed on the outer periphery thereof, and a cylindrical portion 6e is formed outwardly so as to surround the steam outlet 6c. Is formed. In addition, 7 is interposed between the outer peripheral part of the said mixing case and the said step part 6d, and packing with foamed silicon rubber etc. for preventing the vapor | steam introduced in the mixing case 3 from leaking in the outer cover 6 It is.

  8 is a flange portion 8a placed on the opening on the back surface side of the step portion 6d of the outer cover 6, and has a large opening diameter on the flange portion 8a side, and is tapered toward the opening end. A nozzle pipe made of a metal such as brass made of a truncated cone-shaped cylinder part 8b is fitted so that the cylinder part 8b faces the inside from the steam outlet 3c side formed in the mixing pipe 3 It is fixed. Further, the cylindrical portion 8b is formed so as to become thinner toward the opening end 8c.

By fitting the cap 10 into the cylindrical portion 6e, the water absorbing body 9 can be fixed to the step portion 6d of the outer cover 6.

  Next, the operation will be described based on the above-described configuration. When steam is supplied from the steam generator into the steam pipe 1, the steam is supplied from the steam outlet 1 a into the mixing pipe 3 and into the outer pipe 2. Air pressurized from the steam generator is also supplied into the mixing tube 3. Therefore, the steam supplied into the steam pipe 1 is sent into the mixing pipe 3 by the pressurized air supplied from the outer pipe 2, the steam and air are mixed in the mixing pipe 3, and the pressurized steam is mixed. It becomes. The pressurized steam in the mixing tube 3 passes through the nozzle pipe 8, passes through the cap 10 through the steam outlet 6 c of the outer cover 6, and is sprayed on the face of the patient.

  By the way, although the steam pipe 1 through which high-temperature steam passes reaches a considerable temperature, the steam pipe 1 is covered with a gap by the outer pipe 2, so that the outer pipe 2 is heated to a high temperature by the heat from the steam pipe 1. In addition, since the mixing tube 3 into which the steam flows is also covered with the outer cover 6 through the air gap, the outer cover 6 does not become hot, so the practitioner holds it in his hand. It is not hot, and cracks can be prevented by variations in chemicals and molding.

  Further, since the mixing tube 3 is covered by the outer cover 6, the temperature difference between the inside and the outside of the mixing tube 3 is small, and when the steam flows, the temperature becomes high in a short time. The nozzle pipe 8 faces the inside of the mixing tube 3, is made of the same metal as the mixing tube 3, and is formed in a tapered shape toward the opening end of the cylindrical portion. In addition, since it is formed so that the wall thickness decreases toward the opening end 8c, water droplets due to condensation do not accumulate at the opening end 8c of the nozzle pipe 8, and travel through the inside of the cylindrical portion 8b of the nozzle pipe 8. Water droplets do not drop outside.

  Even if water droplets are discharged from the nozzle pipe 8, the water absorbing body 9 is attached to the steam outlet 6 c of the outer cover 3 by the cap 10, so that the water drops are absorbed by the water absorbing body 9 and dripped down to the outside. There is no.
