Claims

[Scope of utility model registration request]

A cylinder containing anesthetic gas, a nasal mask, a conduit connecting the nasal mask and the cylinder, and a conduit provided in the conduit to allow gas to flow into the nasal mask by negative inhalation pressure of breathing acting within the nasal mask. a first check valve that allows introduction of the anesthetic gas; and a first check valve provided on the nasal mask to introduce air into the nasal mask by the nitrogen suction negative pressure to dilute the anesthetic gas introduced into the nasal mask; an exhalation suction tube having one end connected to the nasal mask and the other end extending outdoors, the second check valve having a negative pressure source and the exhaled air discharged into the nasal mask being discharged outdoors; a negative pressure leak hole that is open to the atmosphere and is provided in the exhalation suction tube between the nasal mask and the negative pressure source; and a negative pressure leak hole that is provided in the negative pressure leak hole and that is configured to adjust the effective diameter of the negative pressure leak hole. including a mechanism;
By operating the adjustment mechanism, the amount of air introduced into the mask via the second check valve can be adjusted in accordance with the negative inspiratory pressure acting within the nasal mask, thereby increasing the dilution concentration of the inhaled anesthetic gas. An inhaler sedative that is adjustable.
