Abstract

The utility model provides a disposable laughing gas inhalation anesthesia sedation pipeline which comprises a gas inlet pipeline, an inhaler and a gas exhaust hole, the gas inlet pipeline is communicated with the inhaler, the gas exhaust hole is formed in the inhaler, the gas inlet pipeline is communicated with a gas supply pipeline of a laughing gas machine, and the inhaler comprises a lip tube and a nasal plug. The lip tube is communicated with the air inlet pipeline, the left end and the right end of the lip tube are respectively provided with a first air channel, a second air channel is arranged in the nose plug, the nose plug is arranged on the lip tube, and the first air channels are communicated with the second air channel in a matched mode. The inhaler with a novel structure is formed by the lip tube and the nasal plug, and compared with a nasal mask, the inhaler has the advantages that the size is small, the nose of a patient cannot be covered, and oral operation of medical staff cannot be affected; on the other hand, aversion of the patient cannot be caused; and thirdly, the nose plug is in the shape of an elliptical table, so that the nose plug can meet the requirements of patients with different nostril sizes, and a plurality of annular arc-shaped bulges are arranged on the inclined surface of the elliptical table, so that the nose plug can be better attached to the nasal cavity of the patient, gas escape is avoided or reduced, and reduction of the sedation effect is avoided.
