[0025] 以下将具体说明如何将压カ计130所测得的压カ资料转换成流量资料,以及如何根据流量资料来取得面罩170端的漏气量。 [0025] The following will specifically explain how the pressure gauge conversion ka 130 ka measured pressure data into traffic information and how to obtain the amount of leakage of the mask 170 according to the traffic information ends.

[0026] 图2是本发明实施例正压呼吸装置的漏气量取得方法的流程图。 [0026] FIG 2 is a flowchart showing the amount of leakage positive pressure breathing apparatus of the embodiment of the method of the embodiment of the present invention is achieved. 请同时參照图I与图2,本实施例的正压呼吸装置的漏气量的取得方法包括下列步骤。 Referring to FIGS. I and 2, the leakage amount of positive pressure breathing apparatus obtaining method of this embodiment includes the following steps. 首先,如步骤S210所述,建立压カ与流量的转换公式。 First, as step S210, the conversion formula establishing ka pressure and flow. 压カ与流量的转换公式的建立方法例如包括下列步骤。 The method of conversion formulas established ka pressure and flow, for example, includes the following steps. 首先,于正压呼吸装置100的空气泵120在多个固定转速下,调节正压呼吸装置100的面罩170端的漏气程度,并量测空气泵120的出风ロ124在每ー固定转速下的压カ与流量的对应关系。 First, a positive pressure breathing apparatus 120 of an air pump 100 at a plurality of fixed speed, adjusting the degree of positive pressure breathing mask leakage means 170 end 100 of the air pump and the measured wind 120 ro 124 at a fixed speed in each ーka correspondence relationship between pressure and flow. 之后,根据每ー固定转速下的压カ与流量的对应关系,取得每ー固定转速下的压カ与流量的转换函数,而所述压カ与流量的转换公式包括多个压カ与流量的转换函数。 Thereafter, according to the corresponding relationship between every ー grades pressure and flow at fixed speed, to obtain the transfer function of the pressure and flow grades under each ー fixed speed, and the conversion formula of the pressure and flow ka ka comprises a plurality of pressure and flow conversion function. 每ー压力与流量的转换函数对应到空气泵120的不同转速。 Each ー transfer function corresponding to the pressure and flow speed of the air pump 120 is different. 也就是说,本实施例是将正压呼吸装置100的空气泵120固定在ー个固定转速下运作,接着调节正压呼吸装置100的面罩170端的漏气程度,并通过压カ计130与流量计(图未示)量测空气泵120的出风ロ124的压力与流量的对应关系。 That is, the present embodiment is an air pump 100 of the positive pressure breathing apparatus 120 is fixed ー fixed rotational speed operation, positive pressure breathing mask and then adjusting apparatus 100 ends the degree of leakage 170, and 130 through the pressure and flow meter ka meter (not shown) measuring the air pump 120 of the air pressure and flow rate corresponding relationship ro 124. 然后,根据固定转速下的压カ与流量的对应关系,取得ー个固定转速下的压カ与流量的转换函数。 Then, according to the correspondence ka pressure and flow at fixed speed, to obtain the transfer function of the pressure and flow ka ー at fixed speed. 然后,再重复前述步骤,以取得多个压カ与流量的转换函数。 Then, repeating the foregoing steps, the transfer function to obtain a plurality of pressure and flow grades. 该压カ与流量的转换公式例如是包含多个压カ与流量的转换函数,即Q = f (P)。 The conversion formula ka pressure and flow, for example, comprising a plurality of voltage conversion function ka and flow, i.e. Q = f (P). 其中Q为流量资料,而P为压カ资料。 Where Q is the flow of information, and P is the pressure ka information.

[0027] 接着,如步骤S220所述,通过压カ与流量的转换公式将正压呼吸装置100的压カ计130测得的压カ资料转换成流量资料。 [0027] Next, as step S220, the conversion formula by pressing the pressure and flow ka positive pressure breathing apparatus 100 ka pressure gauge 130 measured data is converted into traffic information ka. 更详细地说,将压カ资料转换成流量资料的方法例如是根据压カ资料于取得当时的空气泵120的转速来选取对应的压力与流量的转换函数。 More specifically, the method of converting data into ka pressure flow data, for example, the time to obtain the rotational speed of the air pump 120 under pressure ka information conversion function to select the corresponding pressure and flow rate. 然后,通过所选取的压カ与流量的转换函数将压カ资料转换成流量资料。 Then, the transfer function of the selected pressure and flow of the pressure ka ka data into a data flow. 举例来说,当压カ资料是在空气泵120的转速为每分钟5000转(即5000RPM)时取得,则选取对应5000RPM的压カ与流量的转换函数,并将所测得的压カ资料输入所选取的压カ与流量的转换函数中,以算出流量资料。 For example, when obtaining information ka pressure pump 120 is an air speed of 5000 revolutions per minute (i.e. 5000RPM), the transfer function of the selected pressure and flow rate corresponding to 5000RPM ka, and the measured pressure data entry ka the selected transfer function ka pressure and flow in order to calculating traffic data.

[0028] 然后,如步骤S230所述,计算所取得的流量资料与标准流量的差异以取得漏气、量。 [0028] Then, as the step S230, the difference data traffic flow is calculated with the standard made to obtain leakage amount. 在这里所指的标准流量是指在面罩170端未产生漏气情形时的流量。 Standard flow referred to herein means a flow rate in the end of the mask 170 does not generate leak situation.

[0029] 需注意的是,上述流量计是在建立压カ与流量的转换公式时才需要。 [0029] It should be noted that the above flowmeter is needed only when ka conversion formula established pressure and flow. 本发明的设计概念之ー是利用压カ与流量的转换公式将压カ资料转换成流量资料,但并不限定其应用的方式。ー design concept of the present invention is the use of the conversion formula ka pressure and flow data converting ka pressed into the traffic data, but the embodiment is not limited to its application. 也就是说,将压カ资料转换成流量资料的步骤以及根据流量资料取得面罩170端的漏气量的步骤除了可直接在正压呼吸装置100的控制单元140实现外,还可在外部装置(如计算机)中进行压力资料与流量资料的转换步骤以及根据流量资料推算出漏气量的步骤。 That is, the step of converting the data into a data flow and pressure of air leakage ka end face mask 170 according to the step of obtaining traffic data in addition to the external device 140 may be implemented directly on the outer positive pressure breathing apparatus control unit 100, may also (e.g. pressure data and flow data converting step and a step of estimating the amount of leakage flow according to a computer data) is performed. 因此,在一个实施例中,即使所使用的正压呼吸装置的控制单元不具备将压カ资料转换成流量资料的功能,也可将记录有压カ资料的记录单元150电性连接到外部装置,以进行压カ资料与流量资料的转换步骤以及根据流量资料推算出漏气量的步骤。 Thus, in one embodiment, the control unit even when positive pressure breathing apparatus used does not have to convert the data into pressed ka flow data function can also be recorded with a recording unit 150 is electrically connected to voltage ka data to an external device to perform data compression grades and flow data converting step and a step of blow-by gas flow amount of the information deduced.

[0030] 另外,在另ー实施例中,压カ与流量的转换公式也可以是Q = f(R,P),其中Q为流量资料,R为空气泵120的转速,而P为压カ计130所测得的压カ资料。 [0030] Further, in another ー embodiment, the conversion formula pressure ka and flow may also be Q = f (R, P), where Q is the flow rate data, R is the rotational speed of the air pump 120, and P is the pressure ka Total 130 ka pressure data measured. 这样,将压カ资料转换成流量资料的步骤如下。 Thus, converting the pressure flow data into data ka steps. 首先,取得空气泵120的转速与在该转速下压カ计130所测得的压カ资料。 First, to obtain the rotational speed of the air pump 120 and the pressure data at the speed ka ka pressure gauge 130 measured. 然后,通过压カ与流量的转换公式,即Q = f(R,P),将压カ资料转换成流量资料。 Then, by the conversion formula ka pressure and flow, i.e. Q = f (R, P), to convert the traffic data into a data compression grades.

[0031] 综上所述,本发明的正压呼吸装置及其漏气量的取得方法至少具有下列优点其中之一: [0031] In summary, the positive pressure breathing apparatus and method of obtaining the amount of leakage of the present invention wherein at least one of the following advantages:
