具体实施方式[0051]加湿理论 DETAILED DESCRIPTION [0051] Humidification Theory

[0052]湿度代表空气中的水蒸气含量。 [0052] Representative moisture vapor content of the air. 湿度通常用两种方法测量:绝对湿度(AH)和相对湿度(RH)。 Humidity generally measured in two ways: absolute humidity (AH) and relative humidity (RH). 绝对MJg是根据每体积重量0fifl录的水的实际含量。 The absolute water content MJg actual weight per volume of 0fifl recorded. 绝赠显度通常以克每立方米(g/cm3)或毫克每升(mg/L)测量。 It must typically presented significant degree in grams per cubic meter (g / cm3) or milligrams per liter (mg / L) measured.

[0053]相赠显度是气体中实际7K蒸气含量相对于在任一指定鹏下携带水的能力的百分比。 [0053] The gift of a significant percentage of the actual gas 7K vapor content of the water-carrying capacity at any given under Peng. 空气携带水蒸气的能力随着空气温度的升高而提高。 Water vapor carrying capacity of the air increases as the air temperature increases. 对于具有稳定的乡Wt显度的空气,相赠显度将随着空气纟鹏的升高而减小。 Having an air stable for rural Wt significant degree, with the gift of Si Peng significantly increased air decreases. 反之,对于水饱和空气(即100。/。RH),如果温度下降,过多的水将从空气中冷凝。 Conversely, for air saturated water (i.e. 100./.RH), if the temperature drops, excess water is condensed from the air.

[0054]人所呼吸的空气被气道加热并加湿到37'C的温度和100%RH。 Air [0054] The human respiratory tract is heated and humidified air to a temperature of 37'C and 100% RH. 在这一温度下,绝X^显度大约在44mg/L。 At this temperature, the absolute X ^ significant degree of about 44mg / L.

[0055]用于CPAP的加湿[0056]ISO8185要求医用加湿器能提供最小10mg/LAH,以及当患者的上气道被绕过时最小为33mg/L。 [0055] CPAP is to humidify [0056] ISO8185 requires medical humidifier to provide a minimum 10mg / LAH, and when the patient's upper airway is bypassed when the minimum of 33mg / L. 这些最小要求是以输入干空气时计算出的。 These minimum requirements are calculated when the input of dry air. 这些最小要求也仅适于短期iOT。 These minimum requirements are also only suitable for short iOT. 这些最小要«常不足以使鼻部和上气道千燥的症状最小化。 To minimize these «often enough to make the nose and upper airway symptoms was dry minimized. 在正常操作情况下,患者或临床医生应当能够将从环境中传输给患者接口的空气纟鹏设定至大约37°C。 Under normal operating conditions, the patient or clinician should be able to transmit air from the environment to the patient interface Peng Si is set to about 37 ° C. 如果呼吸装置没有提供报警系统或指示器,根据IS08185的51.61-51.8部分,在正常和单一默认情况(single fault condition)下,传输给患者接口的空气纟,应当不超过41°C 。 If the breathing system or device does not provide a warning indicator, according to the IS08185 51.61-51.8 part, under normal and single default (single fault condition), the transmission to the air Si patient interface should not exceed 41 ° C.

[0057]对于CPAP, 44攀的上限7乂平可能是不适合的,因为患者的上气道没有被绕过。 [0057] For CPAP, 44 7 qe climbing limit level may not be suitable, since the patient's upper airway is not bypassed. 另一方面,10mg/L的下限7jC平可倉树于CPAP来说太低了,尤其fet于口腔漏气的患者。 On the other hand, 10mg / L of lower limit 7jC CPAP level may be too low in the cartridge trees, especially fet leakage in the patient's mouth.

[0058]虽然没有对确定CPAP所需的湿度的最小7jC平进行研究,但Wiest等(Sto,第24巻第4期,第435*0页,2001年)发5舰于北美和欧洲的患者,当CPAP治疗没有使用加湿器系统时,10mg/L的平均绝)^显度太低了。 [0058] Although not required to determine the minimum 7jC CPAP humidity level research, but Wiest, etc. (Sto, Volume 24 Issue 4, 435 * 0, 2001) issued 5 ship to North American and European patients when the humidifier system does not use CPAP therapy, 10mg / L of absolute mean) ^ significantly too low a. 这一研究试验了两种加湿器,两种加湿器都提供至少23mg/L的绝X寸湿度。 This study tested two humidifiers two humidifiers provide at least 23mg / L of absolute humidity X inch. Wiest等总结出对于CPAP需要超过IS08185的10mg/LAH的水平,但是可能低于研究中所使用23mg^L AH。 Wiest et summarizes studies 23mg ^ L AH used for CPAP level IS08185 need of more than 10mg / LAH, but may be less than. 申请人已经确定大约20-30mg/L的绝对湿度提供适当的患者舒适性。 Applicants have determined that about 20-30mg / L absolute humidity provide adequate patient comfort.

[0084]参考图7,环境空气的饱和^^显度可以由水蒸气的湿度特性计算。 [0084] Referring to Figure 7, the saturation of the ambient air significantly ^^ can be calculated by the humidity properties of the steam. 参见, 例如,Y.钱吉尔,麦克劳-希尔的热传递(HeatT腿fer,YC,l,McGraw疆),1998 (958-59页,表A9)。 See, e.g., Y money Gill, McGraw - Hill heat transfer (HeatT leg fer, YC, l, McGraw Xinjiang), 1998 (pages 958-59, table A9). 或者参见,例如,1997年发行的工业用7jC和7K蒸气热力性质计算公式IAPWS (Release on the IAPWS Industrial Formulation 1997 for the Thermodynamic Properties of Water and Steam),国际水和水蒸气性质协会(The International Association for the Properties of Water and Steam ) , 1997年9月,德国,埃尔兰根(Erlangen)。 Or see, for example, issued in 1997 industrial formula IAPWS (Release on the IAPWS Industrial Formulation 1997 for the Thermodynamic Properties of Water and Steam), the International Association of Water and Steam with 7jC and thermodynamic properties of steam 7K (The International Association for the Properties of Water and Steam), in September 1997, Germany, Erlangen (Erlangen). 如图7所示,绝赠显度以mg/L表示,即每单位#%口、空气中的水蒸气质量,其中条件是环境温度和标准(海平面)压力,或ATPS。 7, the absolute presented significant degrees in mg / L, i.e., per port #%, mass of water vapor in the air, where the conditions are ambient temperature and standard (sea level) pressure, or ATPS. 环境空气的乡M湿度AHa可以由对应于水蒸气的湿度特性的任意方程式或査找表来限定。 Rural ambient air humidity AHa M may be defined by the characteristics of the humidity of water vapor corresponding to any equation or a lookup table. 例如,下面的二次方程: For example, the following quadratic equation:

AHa:RHa'(K广K2'Ta+K3'Ta2) (1), AHa: RHa '(K wide K2'Ta + K3'Ta2) (1),

其中RHa是环境空气的相对湿度,Ta是环境空气的温度,&、 K2和K3是系数。 Wherein RHa is the relative humidity of the ambient air, Ta is the ambient air temperature, &, K2 and K3 are coefficients. 例如系数K^ K2、 K3可以根据经验确定,比如ii31曲线拟合得到数据。 For example, the coefficient K ^ K2, K3 may be empirically determined, such as ii31 curve fitting the data obtained. 例如JQ可以等于7.264, K2可以等于0.09276,而K3可以等于0.02931。 JQ example, may be equal to 7.264, K2 may be equal to 0.09276, and K3 may be equal to 0.02931.

[0085]面罩处气流的目标温度Tm和面罩处的目标相X^显度RHm同样限定了面罩处的绝赠显度AHm,如下面的方程式所限定的: [0085] objectives and the target temperature Tm at the mask at the mask airflow X ^ significant degree RHm same absolute grant defines a significant degree at the mask AHm, as defined by the following equation:

AHnFRHm'(K广K2'Tm+K,Tm2) (2), AHnFRHm '(K wide K2'Tm + K, Tm2) (2),

其中,例如K尸7.264, K2=0.09276,而&=0.02931。 Wherein, for example, K corpse 7.264, K2 = 0.09276, and 0.02931 = &.

[0086]由方程式(1)所确定的环境绝X^显度AHa和由方程式(2)所确定的面罩处的绝X^显度AHm之间的差值AAH等于由加湿器4加入到气流中的绝赠显度。 [0086] by equation (1) determined absolutely environment and X ^ AHa significant degree by equation (2) the determined absolute difference X ^ at the mask between AAH was added by the humidifier is equal to the degree AHm airflow 4 the absolute gift noticeable degree. 当然,如果AHm〈AHa,不需要进行加湿。 Of course, if AHm <AHa, no need for humidification. 给定通过加湿器桶的流量F (L/min), 可以使用描述加湿器响应的衍生的方程式来确定水的蒸魏率E。 Given flow rate through the humidifier tub F (L / min), may be derived using the equation described in the humidifier in response to determining the rate of water vapor E. Wei 例如,在一个实施例中,蒸魏率可以ffl^以下方程式由流量和乡树t鹏的变化确定: For example, in one embodiment, the rate can be distilled off Wei ffl ^ and the following equation is determined by the flow rate change Peng t rural tree:

E(g/hr)=AAH(mg/L) 'F(L/min) '(60min/hr) '0.001g/mg (3)。 E (g / hr) = AAH (mg / L) 'F (L / min)' (60min / hr) '0.001g / mg (3).

[0087]作为一个实例,对于使用图6中的系纖行的CPAP治疗,供应10 cmH20的压力以治疗0SA的患者。 [0087] As an example, for a CPAP treatment using the web-based line in FIG. 6, the supply pressure of 10 cmH20 to treat the patient 0SA. 在10cmH2O时,流量F大约是35L/min,其等于在预定压力下的面罩通风流量。 When 10cmH2O, the flow rate F is about 35L / min, which is equivalent to the mask vent flow at a predetermined pressure. 在环境温度Ta是20。 In the ambient temperature Ta is 20. C和环境相对湿度RHa是50% 的情况下,根据方程式(1),进入加湿器的空气的绝对湿度AHa等于0.5*17.3=10.4mg/L。 C and ambient relative humidity RHa is 50% of the cases, according to equation (1), the air entering the humidifier absolute humidity AHa is equal to 0.5 * 17.3 = 10.4mg / L. 假设患者选择面罩温度Tm为25r并且相X啦显度被选择或者自动设定为90%,则根据方程式(2 ),面罩处的乡MM度AHm等于0.9*23.3=20.9mg/L。 Suppose the mask temperature Tm of selected patients with X and 25r significant degree it is selected or automatically set to 90%, according to equation (2), Township of MM AHm at the mask is equal to 0.9 * 23.3 = 20.9mg / L. 加湿器所增加的绝对湿度AAH等于20.9—10.4=10.5mg/L。 Humidifier increased AAH absolute humidity equal to 20.9-10.4 = 10.5mg / L. 根据方程式(3),加湿器的蒸发速率E因此确定为E=(10.5mg/L)《35L/min) ,(60min/hr) '(0.001g/mg"22g/hr。 Equation (3), so the humidifier evaporation rate E is determined as E = (10.5mg / L) "35L / min), (60min / hr) '(0.001g / mg" according to 22g / hr.

[0088沐的蒸发速率与其蒸气压力相关,其由液态水的温度驱动。 Evaporation rate [0088 Mu vapor pressure associated therewith, which is driven by the temperature of the liquid water. 一般来说, 水温每上升1(TC,饱和蒸汽压力就几乎增加一倍。参见,例如,Y钱吉尔,麦克劳-希尔的热传逸1998 (958-59页,表A9)。或者参见,例如,1997年发行的工业用^C 和水蒸气热力性质计算公式IAPWS,国际水和水蒸气'M协会,1997年9月,德国,埃尔兰根。另外,环境空气水含量,即由环境空气鹏和环境空气相赠显度所确定的已经存在于环境空气中的水的蒸气压力,降低了蒸发速率。环境空气的大气压也会影响蒸发速率,但不及水温增加和环境空气水含量对蒸发速率的影响大。大气压越低,水蒸气蒸发越快,例如海拔越高水蒸气蒸发越快。 Generally, the temperature rise per 1 (TC, saturated vapor pressure is almost doubled see, e.g., Y money Gill, McGraw - Hill heat transfer Yi 1998 (pages 958-59, table A9) or see , e.g., industrial water vapor and ^ C release 1997. thermodynamic properties of IAPWS formula, international water and steam 'M Association, September 1997, Germany, Erlangen. Further, the ambient air water content, i.e., the Peng ambient air and ambient air pressure of the water vapor gift already present in the ambient air is substantially of the determined evaporation rate is reduced. ambient air atmosphere also affects the evaporation rate, but less than the ambient air temperature and the increase of water content large influence evaporation rate. the lower the atmospheric pressure, the faster the evaporation of water vapor, such as water vapor evaporated faster the higher altitudes.

[0089]加湿器桶内的7jC温可以闭环控制。 [0089] The temperature of the humidifier tub may 7jC closed loop control. 可替代地,水下的加热元件的温度也可以闭环控制。 Alternatively, the temperature of the heating element may be underwater closed-loop control. 其它参数可用于闭环控制的设定点。 Other parameters may be used to set the closed loop control point. 例如,蒸发速率E受至咖湿器桶中水蒸气的饱和度柳艮制。 For example, the evaporation rate E by the coffee to water vapor in the humidifier tub saturation Liu Gen system. 桶中的水蒸气饱和度依赖于从气流发生器流入到加湿器的空气的纟鹏。 Water vapor saturation is dependent on the flow into the tub from the flow generator to the humidifier Si Peng. 气流发生器可以增加t鍵加湿器的空气的M^,例如,Mil从气流发生器电机所产生的热量。 The flow generator may increase the air humidifier ^ M t keys, e.g., from the flow generator Mil heat generated by the motor.

[0090]蒸发速率和7乂温之间的理论关系也假定加湿器桶中的水蒸气被有效地从桶中去除。 [0090] The theoretical relationship between the evaporation rate and temperature 7 qe is also effectively removed from the humidifier tub is assumed that water vapor in the tub. 但是,通过桶的气流形式可能绕开某些产生水蒸气的容器。 However, the form of the gas flow through the tub may bypass some of the steam generating vessel. 另外,气流的搅动作用可以通过桶中的水均匀传输热量。 Further, agitation gas stream to transfer heat uniformly through the tub water.

[0091]理论关系也假定蒸发速率很大程度上不受桶中空气温度的影响直到达到饱和。 [0091] The theoretical relationship also assumes that the evaporation rate is largely unaffected by the temperature of the air in the tub until saturation. 实际上,例如斷氐环境空气鹏^7jC表面变冷可以减小蒸发速率。 In fact, for example, ambient air off Peng Di ^ 7jC surface cooling may reduce the rate of evaporation. 从加热桶经3l7jC和桶的内壁到达加湿器的夕M则存在着驗梯度。 Reaching through the humidifier tub from the inner wall of the heating barrel and 3l7jC M evening there is a gradient test. 这些鹏梯度可能导致所检测到的温度和实际的水表面的温度之间不一致。 These Peng temperature gradients may cause discrepancies between the detected temperature and the actual water surface. 即使不^ffl皿传感器,温度梯度还是可能造成水#^显度和水表面温度的不一致。 ^ Ffl boat without sensor, a temperature gradient may still cause inconsistency of water and water # ^ significant surface temperature. 蒸发速率与7X^面的温度有关。 ^ Evaporation rate and surface temperature of about 7X.

[0097]在这一比较实例中,虽然传输给患者接口的空气的相对湿度对所有温度都是100%RH,但传输给患者接口的空气的绝对湿度变化很大,例如从12.5mg/L-30.7mg/L。 [0097] In this comparative example, although the transmission to the patient interface relative humidity of air for all temperatures are 100% RH, absolute humidity but a large change in the transmission of air to the patient interface, for example, from 12.5mg / L- 30.7mg / L. 传输给患者接口的气流温度也根据环境空气温度变化。 Transport stream temperature to the patient interface also varies according to ambient air temperature. 因此患者不能提高传输给患者接口的气流温度。 Thus the patient can not increase the temperature of the air transmitted to the patient interface.

[00111]加湿器4可以提供用户可选的设定,其将提供面罩32处预定含7jC量的自动传输。 [00111] The humidifier 4 may provide a user selectable setting that will provide the mask 32 at a predetermined amount of the automatic transmission containing 7jC. 要考虑导致管子30中不期望的冷凝盼瞎况而确定用于被传输的空气含水量的例值。 To consider the tube 30 leading to undesirable condensation hope blind conditions for determining the value of embodiment of the air moisture content being transmitted. 对于上呼吸道正常的^顿者,期望的生理结果是调节空气至近似正常的鼻子吸气状态。 Respect to the upper respiratory tract of normal ^ Dayton who desired physiological result is that conditioned air to approximately normal nose breathing state. 例如,环境空气可以是20'C和25n/。 For example, ambient air may be 20'C and 25n /. RH (4mg/LAH)。 RH (4mg / LAH). 空气可以被加热和加湿到等于大约2(TC和80%RH (14mg/L AH)的状况。因it浏应于在2(TC下80%RH的绝X^显度的14m^的含7R量可以被选择作为例值。加湿器将被设定为具有14mg/L的输出。10mg/L的差值将由加湿器添加。应当认识到虽然此值可以作为例值选用以及加湿器可以配置为包括自动提供此值的用户设定,该例值可以在临床建议的基础上确定或修改,加湿器可以配置为,或者被重新配置为包括自动提供临床确定的含7jC量的用户设定。例如,患者或临床医生可以在大约10mg/L-25mg/L的范围内选择绝对湿度,例如20mg/L,其通常对应于在大约27"C-28'C的温度下70%-80%之间的相对湿度。 Air may be heated and humidified to equal to about 2 Condition (TC and 80% RH (14mg / L AH) a. Because it Liu corresponding to the 2 (TC 80% RH, absolute X ^ significant degree 14m ^ containing 7R the amount may be selected as the value of Example humidifier is set as the output having 14 mg of .10mg / L / L of a difference added by the humidifier. It should be appreciated that although this value may be configured as a value selected embodiments and humidifier comprising automatically providing a user set this value, the value may be determined or modified embodiments based on clinical recommendations, the humidifier may be configured, or reconfigured to provide a user-containing 7jC clinically determined amount is set to include an automatic example , the patient or clinician may select an absolute humidity in the range of about 10mg L-25mg L range / /, for example, 20mg / L, which typically corresponds to between about 27 "C-28'C at a temperature of 70% -80% relative humidity.

[00112]在呼吸装置设置有加热管的情况下,CPAP系统中传输空气的实际M^ 可以高于室温,典型的大约是29"C。因此,鼻子处的RH值将比同样的绝对湿度值低50%。在呼吸装置不设置加热管的情况下,管内的湿化空气冷却至高于周围环境一到两度。没有加热管时,空气将以大约22'C和70。/。RH (14mg/LAH)被传输。 [00112] In the case where the breathing device is provided with a heating pipe, the actual transmission M CPAP system may be higher than the air temperature ^, typically about 29 "C. Therefore, the RH value at the nose than the same absolute humidity 50% lower. in the case of breathing apparatus is not provided a heating pipe, inside the humidified air cooling tube to a one to two degrees above ambient. no heating tube, and the air will be about 22'C 14mg 70./.RH ( / LAH) is transmitted.

[00113]在最佳设置下,例如10m^,呼吸管中的冷凝将不会发生,除非室温下降到足以导致传输的空气温度下降到其露点(对于典型地传输到具有在22'C环境里操作的CPAP装置的面罩的29'C空气,其露点大约是16'C)以下。 [00113] Under optimal settings, e.g. 10m ^, condensed in the breathing tube will not occur unless the room temperature falls to a temperature sufficient to cause the air to its dew point decreases transmission (typically for transmission to the environment has 22'C mask of the CPAP device operation 29'C air, the dew point is about 16'C) or less. 室温持续下降导致传输的空气温度也下降,接着加热器》破自动减小以降低传输的含7乂量至最佳水平之下,从而避免冷》疑,但是仍然尽可旨断地达到最佳7K平。 Room temperature air results in declining transmission also decreases, and then the heater "break automatically reduced to lower the content of 7 qe transmitted to below the optimal level, in order to avoid cold" suspect, but still as possible to achieve optimum off purpose 7K level.

[00114]参考图13,根据本发明另一个示范实施例的加湿器4包括控制旋钮10, 控制旋钮10包括设定指示器10a。 [00114] Referring to FIG 13, according to the present invention, another exemplary embodiment of the humidifier 4 includes a control knob 10, the control knob 10 includes a setting indicator 10a. 加湿器4包括指示多个设定值的指示物11。 The humidifier 4 comprises a plurality of set values ​​indicative of an indicator 11. 指示物lla可以代表自动设定,其提供默认的含7jC量。 Lla pointer may be representative of automatic setting, providing default content of 7jC. 例如,如图13所示,自动设定指示物lla可以包括,例如T。 For example, as shown in FIG. 13, the indicator is automatically set lla may include, for example, T. 应当认识到可以使用任何其它指示物,例如指示物lla 可以包括文字"最佳"或'自动'。 It should be appreciated that any other indicator may be used, for example, can include text pointer lla "best" or "automatic". 其余的指示物ll可以包括数字,例如M和6-9,其允许使用者增加和减小所传输的湿度。 Ll remaining indicator may comprise a digital, e.g. 6-9 M and that allows the user to increase and decrease the humidity transmitted. 指示物也可以被配置为显示相对湿度或绝对M^和温度的值,例如百分比RH。 Indicator may also be configured to display a relative or absolute humidity and temperature value M ^, e.g. percentage RH. 为了选择默认设定,^ffl者^S制旋钮10的设定指示器10a对准自动设定指示物lla。 To select the default setting, ^ ffl ^ S manufactured by setting indicator knob 10 is aligned with the automatic setting indicator 10a lla. 为了调节湿度體,j顿者将设定指示器lOa对准任意其它指示物ll,或任意其它指示物ll之间的任意位置。 In order to adjust the humidity thereof, j Dayton will set the alignment of any other pointer indicators lOa ll, or any other arbitrary position between the indicator ll. 例如,为了降低湿度设定,使用者可以将设定指示器10a对准数字l-4中的任一个,或其间的任何设置。 For example, in order to reduce the humidity setting, the user can set any of a pointer 10a is aligned in the figures l-4, or any setting therebetween. 同样地,为了增加湿度设定,使用者可以将设定指示器10a X寸准数字6-9 中的任一个,或其间的任何设置。 Likewise, in order to increase the humidity setting, the user can set any of a quasi-digital indicator 10a X inch 6-9, or any setting therebetween. 还应当认识至啦制器可以不是旋钮,例如控制器可以包括诸如LCD的显示器以显示设定,和一个或多个按钮以允许选择设定或改变显示的设定。 It is also to be appreciated that system can not knob, for example, the controller may comprise a display such as an LCD to display the setting, and one or more buttons to allow selection of the displayed set or changed settings.

[00115]如图14所示,当选择自动默认含水量时,即将设定指示器10a对准指示物lla,加湿器4可被控制为使得持续调节加湿器4的加热元件46以使可呼吸气流的含7jC量保持在预定的默iA7jC平,例如14mg/L。 [00115] As shown in FIG. 14, when selecting the automatic default moisture content, setting the pointer 10a is about aligned with the indicator LLA, the humidifier 4 may be controlled such that the continuous control of the heating element 4 of the humidifier 46 so that the respirable 7jC content of the gas stream is maintained at a predetermined level iA7jC silent, e.g. 14mg / L. 如下面更详细讨论的,持续调节加热元件46以保持气流的含水量尽可能接近默认7jC平同时仍然防止管子30内的冷凝或雨水冲洗(rain-out)。 Continuously adjusted as discussed in more detail below the heating element 46 to maintain the water content of the gas stream as close to the default level 7jC while still preventing condensation, or rain water inside the flush pipe 30 (rain-out).

[00116]在使用者睡眠期间,响应于室内状态的变化,例如环境温度、环境相对湿度,禾口/或环境压力,禾口/或响应于气流的变化,加热元件46被控制以保持默认的含水量,例如14mg/L。 [00116] During the sleep users, response to changes in state of the room, such as ambient temperature, relative humidity, mouth Wo / or ambient pressure, opening Wo / or in response to changes in air flow, the heating element 46 is controlled to maintain the default water content, e.g. 14mg / L. 例如,在患者睡眠开始阶段(状态1),室内状态可能是第一温度、第一相X^显度和第一压力。 For example, the patient sleep onset phase (state 1), the first state may be room temperature, of a first phase and a first X ^ significant pressure. 气流发生器可以在患者睡眠开始阶段产生第一气流Q1。 Flow generator may generate a first airflow Q1 stage of sleep onset in a patient. 当患者M将设定指示器10a对准指示物lla而选择自动设定时,加湿器4的加热元件46被控制从而提供默认的含7K量,例如14mg/L。 When the patient M to set the alignment indicator pointer 10a lla automatic setting is selected, the heating element 4 of the humidifier 46 is controlled to provide a content of a default 7K, e.g. 14mg / L.

[0011"尽管状态1在上面被描述为乂寸应于患者睡眠开始期间,但是应当认识到状态1可以对应于从呼吸系统启动开始的时间,例如考虑到传输空气^^在环境温度之上的效应的预热时间。 [0011 "Although the state 1 is described above as corresponding to qe inch patient during sleep starts, it will be appreciated that a state may correspond to the time from the start of the respiratory system startup, for example, taking into account the transmission ^^ above the ambient air temperature warm-up time effect.

[00118]在患者睡眠过程期间,室内状态,包括环境温度、环境相对湿度,和/ 或压力可以变为第二状态(状态2)。 [00118] During the patient during sleep, room status, including ambient temperature, relative humidity, and / or pressure can be changed to a second state (state 2). 气流发生器所产生的气流Q2也可在患者睡眠过程期间变化。 Q2 airflow generated by the flow generator may also vary during the patient's sleep. 加湿器4的加热元件46被控审U为使得在状态2下不管室内状态如何变化,气流的含水量是默认值,例如14mg/L。 4 of the humidifier heating element 46 is controlled such that the U-trial chamber regardless of the change of state in the state 2, the water content of the gas stream is the default value, e.g. 14mg / L.

[00119]同样地,如果患者在启动时(状态1)选择不同的设定,例如M将设定指示器10a对准指示物'9"(从默认值增加含水量)或者指示物'l"(从默认值减小含7jC量),加热元件46被控制以使在状态2下传输至腼罩的含7K量与在状态1下^tl到面罩的含7jC量相同。 [00119] Similarly, if the patient (state 1) choose a different setting at start, for example, indicator M set the alignment indicator 10a '9 "(to increase the moisture content from default) or the indicator' L ' (containing 7jC reduced from the default amount), the heating element 46 is controlled so that the content of 2 7K in the cover shy transmission state to the same content of 7jC tl 1 to the mask in the state ^. 以默认设定值为中心的含水量设定的整个范围响应于所监测到的环境温度、环境相X寸湿度、环境压力和所传输的气流的值而连续且自动地重新调节,这样选定的设定总是被调整为传输选定的含7jC量。 In the entire range of the center value of the water content of the default setting set in response to the monitored environmental temperature, the value of X inch humidity environment, and the ambient pressure and the gas flow transmitted continuously and automatically re-adjusted so that the selected the setting is always adjusted to the content of the selected transmission 7jC.

[00127]参考图16,图示了根据另一示范实施例的呼吸装置的控制系统及其方法。 [00127] Referring to FIG 16, illustrates a control system and method of the respiratory apparatus according to another exemplary embodiment. 在呼吸系统使用过程中,流量可以例如M3! In the course of the respiratory system, for example, can flow M3! AUTOSET⑧控制算法的作用发生改变,该算法可以提供相对较優的流量改变,或者由于产生了漏气,在使用鼻面罩的时候面罩衬垫周边或口周边的漏气,上述漏气可以提供相对较快的流量改变。 AUTOSET⑧ control action algorithm is changed, the algorithm may provide relatively better flow changes, or due to the generation of leakage, when using the nasal mask outside the mask cushion or mouth leak outside of the leak may be provided a relatively fast flow changes. 如果流量变化很快,加热管或软管和/或加湿器的控制可能不足以快速响应以防止管内 If the flow rate changes rapidly, the heating control tube or hose and / or humidifier may not be enough to respond quickly to prevent the inner tube

27的冷凝,因为加湿器改变供应水的温度需要相X寸较长的时间而使得响应较慢。 27 is condensed, because the humidifier to change the temperature of the supply water phase requires a longer time inch X such that the response is slow.

[00128]如图16所示,在S12,确定由流量传感器42所检测至啲或者例如从吹风机速度所估算出的流量的变化或者差值AF。 [00128] As shown in FIG 16, in S12, it is determined by the flow rate sensor 42 to detect changes e.g. GOD or estimated from the blower speed or flow rate difference AF. 差ftAF可以fflil比较周期性间隔所检领倒的或估算到的流量来确定。 Collar or inverted to estimate the flow rate difference can fflil ftAF comparison at periodic intervals determined by the subject. 在S13,差值AF与预定差ttAFp^相比较。 In S13, the difference with a predetermined difference AF ttAFp ^ comparing. 如果周期性的流量之间的差ilAF超过预定量AFptd,处理进展至S14并调节传f俞到患者接口的气術鹏Tm,例如通过使用控制器40禾口/或44来控制加热管30。 If the difference between the periodic ilAF flow rate exceeds a predetermined amount AFptd, and advances the processing to S14 to adjust the air mass f Yu Peng Tm surgery patient interface, for example to control the heating tube 30 by using the port controller 40 Wo / or 44. 如果差1lAF 不超过预定量AFptd,处理进展与关于第一实施例的上述描述相同,在S8根据绝对湿度差值AAH和所检测至啲或估算出的流量计算所需的蒸发速率。 If the difference does not exceed a predetermined amount 1lAF AFptd, processing advances to the above described embodiment is the same as for the first embodiment, the required evaporation rate is calculated in S8 from the absolute humidity difference between AAH and the detected or estimated to GOD traffic.

[00129]如果差值AF是负值,即流量变化为减小,则温度Tm在S14中增力Q。 [00129] If the difference is negative AF, i.e., the flow rate change is reduced, the temperature Tm in S14 booster Q. 温度Tm可以在S14中增加至促以榭专输给患者接口的空气的^g Tm保持在饱和点以上。 Temperature Tm may be increased in order to promote air loss patient pavilion designed interfaces ^ g Tm maintained above the saturation point in S14. 流量的减小也导致在S9中水温或加热元件的^^减小,在S10中计算差值AT,和由控制器40和/或44控制加热元件以减小加湿器的鹏设定点。 The reduced flow rate also results in S9 ^^ water or heating element is reduced, the difference AT is calculated in S10, and controlled by the controller 40 and / or 44 to reduce the heating element set point Peng humidifier. 随着加湿器供应水的温度的减小,纟叙寸湿度AHm有过调的余量而不到达饱和点。 With the decrease of the temperature of the water supply of the humidifier, humidity AHm Si Syrian inch margin of overshoot without reaching the saturation point.

[00130]在Sl 1中确定由温度传感器54所检观倒的温度和所调节的纟鹏Tm之间的差值ATm,并且控制加热管30直到差值ATm基本为零。 [00130] Sl 1 ATm is determined in a difference between the concept and the inverted regulated temperature Tm Si Peng seized by the temperature sensor 54, and controls the heating tube 30 until the difference ATm substantially zero. 经过预定时间周期,在S12中所调节的》,Tm逐渐减小直到加湿器内的供应水的温度减小至咖湿器的新的设定点。 After a predetermined period of time, in S12 the adjusted ", Tm is gradually reduced until the temperature of the water supply in the humidifier is reduced to the wet coffee new set point.

[00131]如果在S11中所确定的流量差衝XF是正值,即流量的变化为增加,并且该流量差歡于预定差值AFptd,贝赃S14中的调节可以是降低》鹏Tm以便保J转色赠显度AHm接近饱和。 [00131] If the flow rate difference determined in S11 is positive impulse XF, i.e., to increase the flow rate variation, and the flow rate difference to a predetermined difference Huan AFptd, shellfish adjusted dirty S14 may be reduced "to Paul Peng Tm J presented significant color change degree AHm close to saturation. 但是,患者可能发现斷氏温度Tm是不舒适的。 However, patients may find it's off temperature Tm is uncomfortable. 在这种情形下,控制器40和/或44可以配置为忽略指示流量增加的流量差值AF。 In this case, the controller 40 and / or 44 may be configured to ignore the difference between the indicated flow increased flow AF.

[00132]这里所讨论的关于示范实施例的加湿器和呼吸装置向对加热加湿器无经验的或新的使用者提供自动的或默认的设定,其设计为在任意给定的使用条件下向被传输的空气提供默认的含7jC量(标称为14mg/L)。 [00132] The humidifier and respiratory apparatus on the exemplary embodiment discussed herein provides an automatic or default setting for the inexperienced or new users of heated humidifiers, which are designed to at any given conditions of use providing default content of 7jC transmitted to the air (nominally 14mg / L). 在患者睡眠过程中,如有需要,将引发自动补偿以降低默认含水量的目标值从而避免空气管内发生冷凝。 In the patient during sleep, if necessary, automatic compensation will lead to reduce the moisture content of the default target in order to avoid condensation within the air tube.

[00133]正确操作根据在此公开的示范实施例的加湿器无须为合适地设定和操作装置而使用任何使用者的知识或干预。 [00133] correct operation of the humidifier according to an exemplary embodiment disclosed herein without a suitable configuration and operation of the device used by any user knowledge or intervention. ^T于那些发现建立合适的力口湿器设定很困难的使用者是很有帮助的。 ^ T to establish an appropriate setting force the mouth moist difficult it is helpful to users who find. 在患者睡眠期间,响应于影响传输空气含7乂量和可能产生冷凝的因素的变化,正确操作被自动地保持,,因素包括环境乡M湿度、环徵显度、相对湿度和压力以及传输空气流量。 During the patient sleeps, response to changes in air containing 7 qe effects of transmission and the amount of the factors that may have condensed, automatically correct operation is held Township M ,, factors include humidity, ring sign significant degree, relative humidity and air pressure, and a transmission flow.

[00134]如果需要,根据4柳者的喜好,可以提供给他们附加设定以微调自动的 [00134] If desired, according to Liu's preferences 4, can provide them with additional settings to fine-tune the automatic

28或默认的设定。 28 or the default settings. 可用设定的满刻度范围被不断他重新调节以保持居中的值在默认含7jC量下被校准,以防±±述的空气传输软管内发生冷凝。 Full-scale range of available settings is continuously re-adjusted to he held centered in the default values ​​to be calibrated at 7jC containing an amount to prevent condensation within the air transfer hose ±± described later. 这意味着,不同于在先技术的加湿器,默认的设定和设定的可用的满刻度范围总是根据实际的环境状态被校准。 This means that, unlike prior art humidifiers, the default setting and the available full scale setting is always calibrated according to the actual range of environmental conditions. 一个地区的气候差异,例如冷湿气候,不会像具有固定加热器设定的装置中的情况一样危及另一个地区的可获得的加湿性能或可获得的设定。 A different climate areas, for example, cold and wet weather, unlike the case of apparatus having a fixed heater was set in the same compromise available humidification performance or available to another area setting.

[00135]例如,4柳者可以确定一个低于默认或自动设定的设定,例如指示物ll 所新己的"3",或高于默认或自动设定的设定,例如指示物ll所t射己的"7",该设定提供最舒适的湿化气流。 [00135] For example, Liu 4 may determine a setting lower than the default or automatic setting, for example, the new pointer has ll "3", or setting higher than the default or automatic setting, such as an indicator ll the shoot had t "7", which is set to provide the most comfortable humidified gas stream. 使用者因此可以选择期望的设定并且传输给患者接口的气流的绝对湿度将是最舒适的,其由患者决定,而不考虑环境状态和/或流量。 Thus the user can select a desired setting and transmitted to the stream of absolute humidity of the patient interface will be the most comfortable, which is determined by the patient, regardless of the state of the environment and / or flow rate.

[00136]加湿器控制的第三实施例 [00136] Humidifier Control Third embodiment

[00137]参考图17,图示了根据另一个示范实施例的呼吸装置的控制系统和处理。 [00137] Referring to FIG 17, illustrates a process control system and respiratory apparatus according to another exemplary embodiment. 对于图17中示范实施例的系统和处理,其Sl-S8和Sll的操作与如上所述的图15中示范实施例的相应步骤操作相似。 And the respective processing step of the system in respect to the exemplary embodiment of FIG. 17 embodiment, which embodiment Sll Sl-S8 and operation as described above in FIG. 15 is similar to the operation of an exemplary embodiment.

[00138]在S8中计算在预定at下传输预定湿度所需的蒸发速率之后,在S15 中,确定加热元件温度阈值,当温度高于该阈值时施加一个固定的占空比,在S16 中确定驱动加湿器的占空比。 [00138] After the calculation of the required transmission at the predetermined humidity at the predetermined evaporation rate in S8, the In S15, the heating element is determined temperature threshold, applying a fixed duty cycle when the temperature is higher than the threshold value, it is determined in S16 driving duty humidifier. 在S15中确定加热元件的温度阈值之后,在S17中判定加热元件的温度是否高于阈值。 After determining the heating threshold element in S15, the determination in S17 whether the temperature of the heating element is above a threshold. 如果加热元件的温度高于阈值(S17:是),贝赃S21中将一个固定的占空比施加至咖热元件。 If the temperature of the heating element is above a threshold value (S17: Yes), S21 will dirty shell a fixed duty ratio is applied to the heat generating element coffee. 如果加热元件的温度不高于阈值(S17: 否),则在S18中将一个100%的占空比施加到加热元件。 If the temperature of the heating element is not above the threshold (S17: NO), then in a 100% duty cycle applied to the heating element in the S18.

[00139]在S19中判定由加热元件鹏传感器48所检测到的加热元件温度是否高于安全操作?鹏。 [00139] In step S19 it is determined by the temperature of heating element 48 detected by the sensor is higher than the heating element for safe operation Peng? Peng. 如果检观倒的加热元件》鹏低于安全操作温度(S19:否),则在S17中再次核査加热元件温度以判定加热元件温度是否高于阈值。 The heating element "If the concept of the subject pour Peng below the safe operating temperature (S19: NO), the verification of the heating element temperature again in S17 to determine if the heating element temperature is above a threshold. 如果所检测到的加热元件^^高于安全操作^g (S19:是),贝赃S20中加热元件的占空比被设定到0%,即加热元件关闭。 If the detected above the safe operation of the heating element ^^ ^ g (S19: YES), in S20 the duty ratio shellfish dirty heating element is set to 0%, i.e. the heating element is turned off.

[00140]加湿器可配置为使用不同类型的容纳供应水的容器或桶来操作。 [00140] The humidifier may be configured to receive a container or tank of water supply used to operate different types. 一种这样的加湿器公开在,例如申请日为2008年9月17日的美国申请61/097,765中,其全部内容在此引入作为参考。 One such humidifier disclosed in, for example, the benefit of US Application No. 61 / 097,765 September 17, 2008, the entire contents of which are incorporated herein by reference. 有两种类型的加湿器桶可以使用, 一种是具有例如不锈钢基底的"可以再度使用的"桶, 一种是带有例如铝基底的"一次性"桶。 There are two types of the humidifier tub may be used, for example, one is having a bucket "can be used again" stainless steel substrate, for example, one with a "disposable" tub aluminum base. 两种基底的热交换特性不同。 Heat exchange characteristics of the two different substrates. 当加热元件被调节为常温时,两种桶可以提供不同的湿度输出。 When the heating element is adjusted to room temperature, two kinds of the tub may provide different humidity outputs. 但是,所期望的是无论明附桶被固定在装置上,湿度输出都是可预料的。 However, it is desirable to clear whether the tub is fixed to the attaching means, the humidity output is predictable. 当有工具检测何种类型的桶被固定在加湿器上时,这也是雌的。 When detecting what type of tool is fixed to the humidifier tub, which is the female.

29[00141]湿度输出与给加热元件提供电力的占空比相关,而不是与加热元件保持的温度相关,如上面参考图17所述。 29 [00141] and humidity output power to the heating element providing a duty cycle related, rather than maintaining the temperature associated with the heating element, as described above with reference to FIG 17. 这是因为在疸定占空比下,以恒定速率给加热 This is because at a given duty cycle jaundice, heated at a constant rate to the

元fM专递电力,系统中电力的主要消耗^M过桶中水的蒸发。 The main power consuming element fM mail, system power ^ M through the evaporation of water in the tub. 实际上,当在同样的 In fact, when at the same

占空比操作时,"一次性的"和"可以再度使用的"桶具有同样的蒸魏率。 Duty cycle operation, the "disposable" and bucket "can be used again" has the same rate of steam Wei.

[00142]也如参考图17戶脱的,示范实施例向加热元件施加恒定占空比的电力, 而不是改变占空比以调节热板的温度。 [00142] Also as described with reference to FIG. 17 off, the exemplary embodiment applies a constant duty ratio of power to the heating element, rather than varying the duty cycle to regulate the temperature of the hot plate. 加热元件是电阻性负载R,例如9.6欧姆, 对于疸定的电势V,例如24V,其通过占空比所限定的定时被打开和关闭。 The heating element is a resistive load R, for example 9.6 ohms, for jaundice given potential V, for example 24V, which is opened and closed by the timing defined by the duty cycle. 这等效于以P=V2/R定义的电功率,例如在100%占空比下的60W电功率驱动加热元件。 This is equivalent to P = V2 / R defined electrical power, electrical power, for example 60W at 100% duty cycle driving the heating elements.

[00143]可以与图15和16所示的实施例中确定加热元件的温度设定点同样的方式确定占空比一M装置的特性,其性能考虑三个变量:环境绝X形显度、传输到患者的气術,和气体传输的流量。 [00143] the same manner as the heating element temperature set point may be determined with the embodiment shown in FIGS. 15 and 16 determines a duty cycle characteristic of the apparatus M, performance considerations which three variables: degree of environment is not substantially X-shaped, gas is transferred to the patient's surgery, and the flow rate of gas transport.

[00144]恒定占空比操作的两个缺点也ail此示范实施例克S艮。 [00144] Two disadvantages of constant duty ratio operation of this exemplary embodiment also ail g S Gen embodiment. 第一,点是加湿器中的水体需要更长的时间从冷的原始状^变暖。 First, water is a point in the humidifier takes longer original shape from the cold ^ warming. 通过在S15中估算温度阈值禾口在S18中以100%占空比驱动加热元件直到其达到温度阈值,然后在S21中转换为对于期望的蒸发速率所需的恒定的或固定的占空比水平,上述缺点得以克服。 By estimating the temperature threshold in S18 Wo port 100% duty cycle driving the heating element until it reaches a temperature threshold, then converted to a constant level or fixed duty cycle required for the desired evaporation rate in S15, in S21 , to overcome the above drawbacks.

[00145]第二个缺点是一旦加湿器桶中的水为空,例如当其中的水己经全部蒸发,加热元件可能达到极高温度。 [00145] The second drawback is that once the humidifier tub is empty of water, such as when all of the water therein has evaporated, the heating element may reach extremely high temperatures. 通过在S19中应用最大安全温度的操作,如果超过该最大安全温度,在S20中设定占空比为0%使得加热元件无效,这样上述缺点得以克服。 By applying a maximum safe temperature of operation in S19, the security if the temperature exceeds the maximum, set in S20 0% duty cycle such that the heating element is not valid, so that the above mentioned disadvantages are overcome.

[00146]图17的示范实施例也可以被用于控制没有加热管的加湿器。 Model [00146] FIG. 17 embodiment may not be used to control the humidifier heating tubes. 在此情况下,患者通过用户接口(例如旋钮或标度盘10和/或控制按钮14)直,制加热元件的调节温度并可以为了舒适而将其调节,这样使用可以再度使用的桶的患者可以趋于设定比使用一次性桶的患者略高的温度。 In this case, the patient via the user interface (e.g., and / or control buttons 14 a knob or dial 10) straight, adjusting the temperature of the system of the heating element and may for comfort to be adjusted, such patients using the tub can once again be used to You may tend to set the ratio of patients to use disposable barrels a slightly higher temperature. 不控制提供给加热元件的电力的占空比,使用可以再度使用的桶的加湿器将比使用一次性桶的加湿器所传输的湿度小, 并朋患者提供较少的有利于加湿的舒适度。 Does not control the duty cycle of power supplied to the heating element, the use of a reusable tub than the humidifier using a small disposable humidifier tub transmitted humidity, and Peng provide less conducive to patient comfort humidified .

[00147]图17的示范实施例也同样向所有的患者提供同等的加湿治疗并保持其操作的简易性。 Model [00147] FIG. 17 embodiment also provides equivalent humidification therapy to all patients and to maintain the ease of its operation.

[00148]加湿器控制的第四实施例 [00148] Humidifier Control Fourth embodiment

[00149]除了控制加湿器的加热元件46的占空比之外,控制器40和/或44还可 [00149] In addition to controlling the duty cycle of the humidifier heating element 46, controller 40 and / or 44 may also

配置为控制空气传输软管或管30的加热元件的占空比。 Configured to control the duty cycle of the air delivery hose or tube 30 of the heating element. 这允许加湿器减少其电源的总容量。 This allows the humidifier to reduce the total power supply capacity. 加湿器加热元件和加热管可以分享电力负载,这样当加湿器加热元件或力口热管可能获得其全电流,例如在24V下瞬时电流2,5A,它们决不被同时致动。 The humidifier heating element and the heated tube may share power load, such that when the humidifier heating element or heat pipe opening force may obtain its full current, for example 2, 5A instantaneous current at 24V, they will not be actuated simultaneously. 控制器40禾Q/或44计算占空比以分配给加湿器和加热管中的每一个,这样合成的占空比不超过100%。 The controller 40 Wo Q / or 44 calculate the duty ratio to assign to each of the humidifier and heated tube, thus synthesized duty is not more than 100%. 控制器40和/或44也使加湿器和加热管的加热周期同步,这样使得它们不会交叠。 The controller 40 and / or 44 and also the humidifier heating tube heating cycle synchronization, so that they do not overlap. 控制器40和/或44可配置为根据气流发生器提供的占空比定期的打开和关闭每个加热元件,使得在同一时间只有一个装置被打开。 The controller 40 and / or 44 may be configured to periodically open and close each heating element is provided in accordance with the duty ratio of the flow generator, so as to be open at the same time only one device. 这样的电力管理控制被公开在,例如申请日是2008年9月10日的美国申请61/095,714中,其全部内容在此引入作为参考。 Such power management control are disclosed in, for example, US application filing date is September 10, 2008 61 / 095,714, the entire contents of which are hereby incorporated by reference.
