Problems solved by technology

However, when the flow rate of fresh gas changes, the adjustment effect of this oxygen supply mode is weakened, and the pressure change of the fresh gas outlet is still very large.

Abstract

The invention discloses a gas pressure stabilizer for an anesthesia machine and the anesthesia machine provided with the same. The gas pressure stabilizer comprises a valve body, a fast oxygen supply passage and a diffusing structure. The valve body is provided with a fresh gas inlet and a common gas outlet. The fast oxygen supply passage is provided with a fast oxygen supply inlet and a fast oxygen supply jet spout. The diffusing structure is spaced from the fast oxygen supply jet spout, so that a negative pressure area is formed. The diffusing structure is provided with an inlet and an outlet, the outlet is communicated with the common gas outlet, the inlet is opposite to the fast oxygen supply jet spout, moreover, the inlet, the fresh gas inlet and the fast oxygen supply jet spout are communicated with the negative pressure area, and the diffusing structure is also provided with a positive pressure feedback passage communicated with the fresh gas inlet. According to the gas pressure stabilizer disclosed by the invention, the pressure of the fresh gas inlet can be nearly kept unchanged, consequently, the supply flow of fresh gas can be nearly kept unchanged, and is within the full range of fresh gas input flow, and the influence of fast oxygen supply on the flow of fresh gas can be reduced to an acceptable degree.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a gas regulator for an anesthesia machine and an anesthesia machine with the same. Background technique [0002] Fresh gas supply and rapid oxygen supply are the basic functions of the gas circuit of the anesthesia machine. Usually, the two gases are merged into a common channel and then passed into the anesthesia circuit. When the anesthesia machine is working normally, only fresh gas is passed into the anesthesia circuit. When the anesthesia machine circuit needs to supplement oxygen rapidly, the rapid oxygen supply valve is opened to supply oxygen. After the rapid oxygen supply valve is opened, the flow rate of oxygen is much higher than the flow rate of fresh gas during normal operation, so the pressure in the pipeline rises during rapid oxygen supply, and the pressure of the fresh gas outlet also rises accordingly, resulting in an instant drop in the flow rate of fresh gas....
