Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical vaporizers, in particular to a medical decompression buffer vaporizer. Background Art
[0002] The formation of liquid oxygen requires low temperature or high pressure. During the vaporization process, it must complete the dual processing of absorbing heat and reducing pressure. The temperature of incompletely vaporized liquid oxygen is too low and it carries high pressure. If used directly, it can easily cause harm to the patient and easily lead to safety accidents.
[0003] Existing medical vaporizers often use "a medical vaporizer with a porous vaporization element" disclosed by the announcement number "CN103285488B". The vaporizer adopts a dispersed structure. A single device such as a vaporization element performs simple diversion and vaporization on the fluid from the liquid oxygen bottle. The porous dispersed structure can only have a weak buffering effect on the fluid. The non-adjustable aperture and its planar design prevent the fluid from contacting the resistance from the opposite direction of the fluid. The incompletely buffered fluid enters the vaporization element with strong pressure, and it is difficult to be completely vaporized under the heating effect of the vaporization element. The remaining unvaporized fluid will be a great safety hazard, and the liquid oxygen that has not been completely vaporized after passing through these two structures will directly reach the patient's respiratory system, causing damage to the patient's respiratory system.
