Medical vaporizer

The utility model discloses a medical vaporizer and relates to the field of medical devices. The medical vaporizer comprises a mask and a mist spraying pipe communicated with the mask. The mist spraying pipe is communicated with a liquid medicine cavity, the liquid medicine cavity is internally provided with an oscillation membrane, the liquid medicine cavity is connected with an air pipe, the mask is connected with the mist spraying pipe through a connecting pipe, and the connecting pipe is in a bending type. A check valve is arranged in the mist spraying pipe, and the mask is provided with an exhaling check valve. Compared with the prior art, the mask and the mist spraying pipe of the medical vaporizer are not in the same horizontal direction, vaporization can be conducted on a patient at the recumbent position, the mist spraying pipe is located at the position which is parallel to or lower than an air passage inlet all the time, and suffocation caused by chocking of vaporization water drops can be prevented. Furthermore, the check valve is arranged in the mist spraying pipe, air exhaled by the patient cannot flow back into the liquid medicine cavity to cause pollution. In addition, the exhaling check valve is arranged on the mask, the air exhaled by the patient can be exhausted from the exhaling check valve, and accumulation of carbon dioxide is avoided.
