Description

一种气体流量调节指示器 A gas flow regulating indicator

技术领域 FIELD

[0001] 本发明涉及医疗技术领域,尤其涉及一种气体流量调节指示器。 [0001] The present invention relates to medical technology, and particularly relates to a gas flow rate adjustment indicator.

背景技术 Background technique

[0002] 麻醉机的功能是手术期间对病人进行吸入麻醉和机械通气。 [0002] The anesthetic machine function is to patient inhalation anesthesia and mechanical ventilation during surgery. 在麻醉机工作期间,病人呼吸的气体是在一个带有钠石灰罐的封闭式回路中循环利用的。 Anesthesia machine during work, patient breathing gas in a closed circuit with soda lime in the recycling tank. 该钠石灰罐是用来吸取人体呼出的C02。 The soda lime can be used to draw human exhaled C02.

[0003] 麻醉机在使用的过程中,以下几个原因可能会导致气体的消耗: [0003] anesthesia machines used in the process, several of the following reasons may cause gas consumption:

1、病人气体吸收量(如氧气的吸收量,和麻醉气体的吸收量) 1, patient gas absorption amount (amount of oxygen absorbent, and absorption of anesthetic gases)

2、系统的泄露量 2, the amount of leakage system

3、C02吸收器的C02吸收量。 3, C02 C02 absorption amount of the absorber.

[0004] 以上这些消耗量都可以通过气体监测和计算得到,为了满足临床的使用要求,麻醉机中有一条独立的通道持续补充气体到病人的呼吸回路,该通道补充的气体称为新鲜气体。 [0004] These can be obtained by consumption of gas monitoring and calculation, in order to meet the requirements of clinical anesthesia machine has a separate gas passage is replenished into the patient breathing circuit, the supplemental channel is referred to as fresh gas gas.

[0005] 如图1所示,新鲜气体的形成主要分为两步: [0005] As shown in FIG 1, fresh gas formed mainly divided into two steps:

第一步:氧气02、空气Air或者笑气N20在流量监控器中以不同的流量进行混合;第二步:流量监控器输出的混合气体经过麻药挥发罐后,形成新鲜气体,输送到病人呼吸回路。 Step: 02 oxygen, air or nitrous oxide N20 in Air traffic monitor to different traffic mix; Step: mixed gas flow rate monitoring output after anesthetic vaporizer to form fresh gas, delivered to the patient breathing loop.

[0006] 新鲜气体的总流量设置值必须要大于上述气体消耗量。 [0006] The total fresh gas flow rate set value must be greater than the gas consumption. 但是设置得过大同样会造成浪费。 But it is set too high it will also result in waste. 通常的做法是新鲜气体的总流量不能大于气体消耗量lL/min以上。 The usual practice is the total flow of fresh gas can not be greater than the gas consumption lL / min or more.

[0007] 为了使新鲜气体的总流量满足上述要求,通常使用流量计来设置新鲜气体的总流量,但是现有技术的流量计不能明确指示临床医生当前新鲜气体的总流量是否合适,因此新鲜气体的设置不够精确,容易造成浪费,给临床医生的工作带来很多不便。 [0007] In order to make the total flow of fresh gas meet the above requirement, a flow meter is generally used to set the total flow of fresh gas, but the prior art flowmeter can not explicitly indicated clinician current total flow of fresh gas is appropriate, so fresh gas the setting is not accurate, easily lead to waste, to the work of clinicians bring a lot of inconvenience.

具体实施方式 Detailed ways

[0024] 为了使临床医生(用户)能非常直观的知道当前的新鲜气体设置是否合适,本发明提供了一种气体流量调节指示器,该气体流量调节指示器设计在流量计的用户界面上。 [0024] In order to enable the clinician (user) can be very intuitively know the current fresh gas settings are appropriate, the present invention provides a gas flow regulation indicator, the indicator is designed to adjust the gas flow rate at the meter a user interface.

[0025] 参见图2,为本发明提供的一种气体流量调节指示器实施例一的结构示意图。 [0025] A gas Referring to Figure 2, the present invention provides a flow control indicator diagram of a configuration of the embodiment.

[0026] 本实施例一提供的气体流量调节指示器,包括: [0026] The present embodiment according to a first gas flow adjustment indicator, comprising:

带有流量刻度的流量指示图1和用于指示当前新鲜气体的总流量是否有效的指示区 FIG flow with traffic indication scale for indicating the current 1 and the total flow of fresh gas indication whether the region

2 ;本实施例一中的流量指示图1为竖向棒图。 2; a traffic indication map in the embodiment 1 of the present embodiment is a vertical bar graph.

[0027] 如图2所示,流量指示图1的流量刻度由下至上依次为0.5L/min、lL/min、2L/min、3L/min、4L/min,不同的实现方式中,可以设置不同的流量刻度。 [0027] As shown, a traffic indication map scale flow from the bottom 2 of the order of 0.5L / min, lL / min, 2L / min, 3L / min, 4L / min, different implementations may be provided different flow scale.

[0028] 所述流量指示图1采用流量刻度指示过高流量阈值、最小流量阈值,并指示当前新鲜气体的总流量值所在的位置。 [0028] The traffic indication map indicates a high flow rate using a flow rate scale threshold value, the minimum flow threshold, and indicates the location of the current value of the total flow of fresh gas is located. 另外,其中,流量指示图1采用三角形指示当前新鲜气体的总流量值所在的位置。 Further, wherein the traffic indication triangle indicates the position of FIG. 1 using the total flow of fresh gas current value is located. 当然,还可以采用其他形状来指示当前新鲜气体的总流量值所在的位置,例如,流量指示图1采用直线指示当前新鲜气体的总流量值所在的位置。 Of course, other shapes may also be employed to indicate the location of the current value of the total flow of fresh gas is located, e.g., FIG. 1 by linear traffic indication indicates that the current value of the total flow of fresh gas is located.

[0029] 如图2所示,本实施例一中,过高流量阈值大约为1.5L/min、最小流量阈值大约为0.75 L/min。 [0029] As shown in FIG. 2, one embodiment of the present embodiment, the high flow rate threshold is about 1.5L / min, the minimum flow rate threshold is about 0.75 L / min. 当前新鲜气体的总流量值所在的位置大概是1.25 L/min。 The current position of the total flow of fresh gas where the value is about 1.25 L / min.

[0030] 当所述当前新鲜气体的总流量值大于所述过高流量阈值时,所述指示区2指示新鲜气体的总流量值设置过高;当所述当前新鲜气体的总流量值小于所述最小流量阈值时,所述指示区2指示新鲜气体的总流量值设置过低;当所述新鲜气体的总流量值介于所述过高流量阈值和最小流量阈值时,所述指示区2指示新鲜气体的总流量值设置有效。 [0030] when the current value of the total flow of fresh gas flow rate is greater than the high threshold value, 2 indicates the fresh gas flow rate value indicative of the total area is set too high; and when the total flow of fresh gas current value is less than the when the said minimum flow threshold value, 2 indicates the fresh gas flow rate value indicative of the total area is too low; when the value of the total flow of fresh gas flow rate is between the high threshold and a minimum threshold flow rate, the indicator zone 2 It indicates the total fresh gas flow rate value valid.

[0031] 举例来讲,如图2所示,流量指示图1中指示的当前新鲜气体的总流量值为1.25L/min,该值小于过高流量阈值1.5L/min,但大于最小流量阈值0.75L/min,则在指示区2中,显示“有效”二字,以提示新鲜气体的总流量值设置有效。 [0031] For example in terms of, as illustrated, the total flow of fresh gas in the current traffic indication map indicates a value of 2 1.25L / min, the flow rate is too high which is less than the threshold value 1.5L / min, but the flow rate is greater than the minimum threshold value 0.75L / min, in the area indicated 2, shows "valid" word to prompt the total fresh gas flow rate value valid. 当然,在其他的实现方式中,也可以用不同的颜色或者形状,在指示区中提示过高,过低或者有效三种状态。 Of course, in other implementations, may be a different color or shape, prompt indicating zone is too high, too low or efficient three states.

[0032] 本发明的核心在于气体流量调节指示器的实现过程,如何监测当前新鲜气体的总流量值,在具体实现中可以在图1所示的病人呼吸回路的新鲜气体输入端设置一个流量传感器来监测当前新鲜气体的总流量值。 [0032] The core of the invention is that the gas flow rate adjusting implementation pointer, how to monitor the current value of the total flow of fresh gas, a flow rate sensor may be provided at the input of fresh gas in the patient breathing circuit 1 shown in FIG particular implementation the current value of the monitored total fresh gas flow rate. 此为本领域技术人员熟知的技术方案,在此不再赘述。 This well known to those skilled in the art solutions, which will not be repeated herein.

[0033] 另外,设置新鲜气体的总流量值的流量计有两种:一种是机械控制流量计,另一种是电子控制流量计。 [0033] Further, the total fresh gas flow meter set flow rate value two ways: one is to control a mechanical flow meter, the other is electronically controlled flow meters.

[0034] 其中,机械控制流量计设置新鲜气体的总流量值一般都是通过针阀直接调节氧气、笑气或者空气的流量。 [0034] wherein the mechanical control of fresh gas meter set value of the total flow rate of oxygen are generally adjusted directly by the needle valve, the flow of air or nitrous oxide.

[0035] 而电子控制流量计设置新鲜气体的总流量值有两种方法: [0035] and the electronic meter control set value of the total flow of fresh gas in two ways:

第一种:设置平衡气体,总流量和氧浓度,通过这种方法可以间接计算出氧气流速和平衡气体流速。 The first: balance gas is provided, the total flow rate and oxygen concentration, the oxygen flow rate may be indirectly calculated gas flow rate and balance by this method.

[0036] 第二种:直接设置氧气流速和平衡气体流速(氧气或者笑气)。 [0036] The second: oxygen flow rate directly and balance gas flow (oxygen or nitrous oxide).
