[0005] 2. Leakage of the system
[0012] In order to make the total flow of fresh gas meet the above requirements, a flow meter is usually used to set the total flow of fresh gas, but the flow meter in the prior art cannot clearly indicate whether the current total flow of fresh gas is suitable for the clinician, so the setting of fresh gas is not enough Accurate, easy to cause waste, and bring a lot of inconvenience to the work of clinicians

Embodiment Construction
[0039] In order to enable clinicians (users) to intuitively know whether the current fresh gas setting is appropriate, the present invention provides a gas flow adjustment indicator, which is designed on the user interface of the flowmeter.
[0040] see figure 2 , is a structural schematic diagram of Embodiment 1 of a gas flow adjustment indicator provided by the present invention.
[0041] The gas flow adjustment indicator provided in Embodiment 1 includes:
[0042] Flow indicator with flow scale figure 1 And the indicator zone 2 used to indicate whether the total flow rate of the current fresh gas is valid; the flow rate indicator in the first embodiment figure 1 is a vertical bar graph.
[0043] like figure 2 shown, flow indication figure 1 The flow scales from bottom to top are 0.5L / min, 1L / min, 2L / min, 3L / min, 4L / min. In different implementations, different flow scales can be set.
[0044] The flow indication figure 1 The flow scale is used to indicate the over-h...

The invention provides a gas flow regulation indicator which comprises a flow indicating diagram and an indicating area. The flow indicating diagram indicates a too high flow threshold and a minimum flow threshold and indicates the position of a total flow value of current fresh gas; when the total flow value of the current fresh gas is larger than the too high flow threshold, the indicating area indicates that the total flow value is set to be too high; when the total flow value of the current fresh gas is smaller than the minimum flow threshold, the indicating area indicates that the total flow value is set to be too low; and when the total flow value of the fresh gas is between the too high flow threshold and the minimum flow threshold, the indicating area indicates that the total flow value is set to be valid. Through the gas flow regulation indicator, an interface space can be effectively saved, the threshold position of the minimum required flow and the too high flow threshold position can be obtained extremely visually by users, the total flow velocity of the currently monitored fresh gas can be observed visually, whether the fresh gas flow set at present is too high, too low or effective can be given out qualitatively, and the gas flow regulation indicator is extremely visual and easy to use.
Description
technical field [0001] The invention relates to the field of medical technology, in particular to an indicator for regulating gas flow. Background technique [0002] The function of the anesthesia machine is to provide inhalation anesthesia and mechanical ventilation to the patient during the operation. During the operation of the anesthesia machine, the gas breathed by the patient is recycled in a closed circuit with a soda lime tank. The soda lime tank is used to absorb the CO2 exhaled by the human body. [0003] During the use of the anesthesia machine, the following reasons may lead to gas consumption: [0004] 1. Patient gas absorption (such as oxygen absorption, and anesthesia gas absorption) [0005] 2. Leakage of the system [0006] 3. The CO2 absorption capacity of the CO2 absorber. [0007] The above consumption can be obtained through gas monitoring and calculation. In order to meet the clinical requirements, there is an independent channel in the anesthesia ...
