Abstract
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
The present invention relates to field of medical technology, relate in particular to a kind of gas flow regulation indicator.
Background technology
The function of Anesthesia machine is that intra-operative carries out inhalation anesthesia and mechanical ventilation to patient.At Anesthesia machine duration of work, the gas of patient respiration is to recycle in a closed loop with soda lime tank.This soda lime tank is the CO2 for drawing characteristics of contaminated respiratory droplets.
Anesthesia machine is in the process using, and following reason may cause the consumption of gas:
1, patient's gas absorption amount (as the uptake of oxygen, and the uptake of anesthetic gases)
2, the amount of leakage of system
3, the CO2 uptake of CO2 absorber.
These consumptions can and calculate by gas-monitoring above, and in order to meet clinical request for utilization, independently the lasting make-up gas of passage is to patient's breathing circuit in Anesthesia machine, one, and the supplementary gas of this passage is called live gas.
As shown in Figure 1, the formation of live gas is mainly divided into two steps:
The first step: oxygen O2, air Air or laughing gas N2O mix with different flows in flow monitor;
Second step: the mixed gas of flow monitor output, after anaesthetic volatilization tank, forms live gas, is transported to patient breathing circuit.
The total flow settings of live gas must be greater than above-mentioned gas consumption.But the waste that can cause equally too much is set.Common way is more than the total flow of live gas can not be greater than gas consumption 1L/min.
For the total flow that makes live gas meets above-mentioned requirements, conventionally use traffic meter arranges the total flow of live gas, but whether the flowmeter of prior art can not clearly indicate the total flow of the current live gas of clinician suitable, therefore live gas arrange accurate not, easily cause waste, bring a lot of inconvenience to clinician's work.
Summary of the invention
In order to use clinician (user) can know very intuitively that whether current live gas setting is suitable, the invention provides a kind of gas flow regulation indicator.
A kind of gas flow regulation indicator provided by the invention, comprising:
With the flow index map and the whether effectively indicator of total flow that is used to indicate current live gas of flow scale;

Embodiment
In order to make clinician (user) can know very intuitively that whether current live gas setting is suitable, the invention provides a kind of gas flow regulation indicator, this gas flow regulation indicator designs in the user interface of flowmeter.
Referring to Fig. 2, it is the structural representation of a kind of gas flow regulation indicator embodiment mono-provided by the invention.
The gas flow regulation indicator that the present embodiment one provides, comprising:
With the flow index map 1 and the whether effectively indicator 2 of total flow that is used to indicate current live gas of flow scale; Flow index map 1 in the present embodiment one is vertical rod figure.
As shown in Figure 2, the flow scale of flow index map 1 is followed successively by 0.5L/min, 1L/min, 2L/min, 3L/min, 4L/min from the bottom to top, in different implementations, different flow scales can be set.
Described flow index map 1 adopts flow scale to indicate too high flow threshold, minimum flow threshold value, and indicates the position at the total flow value place of current live gas.In addition, wherein, flow index map 1 adopts triangle to indicate the position at the total flow value place of current live gas.Certainly, can also adopt other shapes to indicate the position at the total flow value place of current live gas, for example, flow index map 1 adopts straight line to indicate the position at the total flow value place of current live gas.
As shown in Figure 2, in the present embodiment one, too high flow threshold is approximately 1.5L/min, minimum flow threshold value is approximately 0.75 L/min.The chances are in the position at the total flow value place of current live gas 1.25 L/min.
In the time that the total flow value of described current live gas is greater than described too high flow threshold, described indicator 2 indicates the total flow value of live gas to arrange too high; In the time that the total flow value of described current live gas is less than described minimum flow threshold value, described indicator 2 indicates the total flow value of live gas to arrange too low; When the total flow value of described live gas is during between described too high flow threshold and minimum flow threshold value, described indicator 2 indicates the total flow value of live gas to arrange effectively.
By way of example, as shown in Figure 2, in flow index map 1, the total flow value of the current live gas of indication is 1.25 L/min, this value is less than too high flow threshold 1.5L/min, but be greater than minimum flow threshold value 0.75L/min,, in indicator 2, show " effectively " two words, arrange effectively with the total flow value of pointing out live gas.Certainly, in other implementation, also can be by different colors or shape, in indicator, point out too high, too low or effective three kinds of states.
