But, above are only the preferred embodiment of the present invention, but be not limited thereto.
This microprocessor 21 in this control box 2 can be connected to link up via wireless transmission method with this microprocessing unit 11 in this gas supply device 1, and the circuit (figure does not indicate) that also can pass through to be arranged in this runner 10 interconnects. Further, this gas supply device 1 can provide this control box 2 to operate required power supply by this circuit.
This disappointing unit 22 can timing, the quantitatively gas in this air bag 31 of venting, to adjust the degrees of expansion of this air bag 31. Thus, it is possible to decrease constriction produced by this this face shield 3 of user 4 prestowage, and then promote the comfort level of this long-term this face shield 3 of prestowage of user 4.
When this user 4 does not have prestowage this face shield 3 (that is, this face shield 3 is not completely coated with the face of this user 4) good, when causing the treatment gas leak that this face shield 3 exports, this microprocessor 21 can receive a disappointing notice from this microprocessing unit 11. When this microprocessor 21 receives this disappointing notice, control this presser unit 23 this air bag 31 is pressurizeed, the face of this user 4 it is close to by making this air bag 31 appropriateness expand, and make this face shield 3 produce displacement, and then make this face shield 3 can again be coated with the face of this user 4, the problem thus solving to lose heart.
Continuing and refer to Fig. 3 and Fig. 4, respectively the control flow chart of the gas supply device of first specific embodiment of the present invention and face shield prevent from losing heart and control the original control flow graph of box. The present invention additionally discloses a kind of air bag controlled method, describes in detail as follows. First as it is shown on figure 3, after this gas supply device 1 is started shooting, need to first set a target blast (step S10), namely, according to the instruction of doctor, set the motor rotary speed of this aerator 12, or directly set discharge pressure of fan or the flow of this treatment gas. After having set this target blast in this step S10, the treatment procedure (step S12) of this respiratory assistance apparatus can be started. Simultaneously, this user 4 needs this face shield 3 of prestowage, and makes this face shield 3 completely be coated with the face of this user 4.
After this treatment procedure starts, this gas supply device 1 transmits a control command to this control box 2 by this microprocessing unit 11, to start this control box 2 (step S14), so as to this air bag 31 on this face shield 3 being initialized by this control box 2.
Then, this microprocessing unit 11 controls this aerator 12 and starts and start pressurization (step S16). In the present embodiment, this step S16 refers to that this microprocessing unit 11 constantly orders this aerator 12 to increase force value, till making this treatment gas of output reach this target blast. Wherein, whether this treatment gas of output has reaches this target blast, is can be detected by this detection unit 14.
After step S16, this gas supply device 1 continues through this detection unit 14 and detects discharge pressure of fan or the flow of this treatment gas, and this microprocessing unit 11 continues to determine whether that the situation lost heart produces (step S18) according to testing result. In the present embodiment, this microprocessing unit 11 mainly can determine whether that whether the discharge pressure of fan of this treatment gas or flow be abnormal, to be confirmed whether to have disappointing situation to produce. For example, this microprocessing unit 11 can in the discharge pressure of fan of this treatment gas more than this target blast, or when the output flow of this treatment gas is more than a target flow, it is judged that have disappointing situation to produce, but be not limited. If situation of not losing heart occurs, then removing one first enumerator (step s20) in this gas supply device 1, wherein this first enumerator loses heart the time (being detailed later) in order to calculate one.
If there being disappointing situation to occur, this microprocessing unit 11 sends this notice of losing heart to this control box 2 (step S22), to order this control box 2 by solving, in the way of adjusting the degrees of expansion of this air bag 31, problem of losing heart. Then, this microprocessing unit 11 judges whether this disappointing time reaches one first setting value (step S24).
More specifically, this microprocessing unit 11 counts mainly by internal this first enumerator (figure does not indicate), to confirm this disappointing time. If this disappointing time has reached this first setting value, represent that this control box 2 cannot solve above-mentioned disappointing problem with this air bag 31. Therefore, this microprocessing unit 11 controls this aerator 12 and increases pressure, to carry out the compensation (step S26) of popping pressure. After this step S26, or this microprocessing unit 11 judges when this disappointing time not yet reaches this first setting value, it is judged that whether this gas supply device 1 decommissions (step S28), i.e. whether this treatment procedure terminates. If it is not, then return to this step S18, this microprocessing unit 11 continues to judge whether have disappointing situation. If so, then this gas supply device 1 decommissions, and controls this control box 2 simultaneously and decommissions (step S30).
After consulting this step S14 execution of Fig. 4, above-mentioned Fig. 3, this microprocessor 21 in this control box 2 can receive this control instruction (step S40) that this microprocessing unit 11 transmits, so as to initial start. After this control box 2 starts, this microprocessor 21 controls this presser unit 23 and this air bag 31 is pressurizeed (step S42), to make this air bag 31 initial bubble. Then, this microprocessor 21 judges whether reach one second setting value (step S44) pressing time.
More specifically, this microprocessor 21 counts mainly by internal one second enumerator (figure does not indicate), to confirm this pressing time of this presser unit 23. If having reached this second setting value this pressing time, representing that this air bag 31 has reached a suitable degrees of expansion, therefore this microprocessor 21 controls this presser unit 23 and stops pressurization (step S46). If not yet reaching this second setting value this pressing time, then this microprocessor 21 controls this presser unit 23 persistent pressure. Technology effect of Fig. 4 is in that, before this user 4 wants this face shield 3 of prestowage, this air bag 31 of Schilling is expanded to a certain degree, so as to make this user 4 can this face shield 3 of cosily prestowage, without after prestowage, produce sense of discomfort in the contact site with this face shield 3.
Continuing and refer to Fig. 5, the disappointing of the first specific embodiment for the present invention prevents flow chart. In the use procedure of this respiratory assistance apparatus, this microprocessor 21 of this control box 2 continues to judge whether to receive this notice (step S50) of losing heart that this gas supply device 1 sends. This notice of losing heart of indication in the present embodiment, is this notice of losing heart that this microprocessing unit 11 sends in this step S22 of Fig. 3.
If not receiving this notice of losing heart that this gas supply device 1 sends, then this control box 2 is not forced this air bag 31 is pressurizeed. Otherwise, if receiving this notice of losing heart that this gas supply device 1 sends, then this microprocessor 21 of this control box 2 controls this presser unit 23, so that this air bag 31 is pressurizeed (step S52).
After this step S52, this microprocessor 21 judges whether this gas supply device 1 decommissions (step S54). If this gas supply device 1 not yet decommissions, then returning to this step S50, this microprocessor 21 continues to judge whether to receive this notice of losing heart that this gas supply device 1 transmits. So as to, this microprocessor 21 from whether continuing to receive the judgement of this notice of losing heart, can learn whether disappointing problem solves. Otherwise, if this gas supply device 1 decommissions, then this control box 2 decommissions (step S56) equally, or can decommission after receiving the instruction that this gas supply device 1 sends.
In above-described embodiment, this air bag 31, only when this face shield 3 has disappointing problem, just can be forced pressurization and then expand. But, in following embodiment, this microprocessor 21 also can the degrees of expansion of this air bag 31 of adjustment, to promote the comfort level of this user 4 this face shield 3 of prestowage.
Consulting Fig. 6, the disappointing of the second specific embodiment for the present invention prevents flow chart. In the embodiment of Fig. 6, this control box 2 has this gas bleeder valve 22, and in the present embodiment, this gas bleeder valve 22 is to realize with an electromagnetic valve. Specifically, this electromagnetic valve is only limited by this microprocessor 21 and is controlled, and only when this electromagnetic valve receives the open command of this microprocessor 21, this electromagnetic valve just can be opened, and then the gas in this this air bag 31 of breather 32 venting. When this microprocessor 21 does not send open command, this electromagnetic valve normality is closed, and the gas in this air bag 31 will not run off.
First, this microprocessor 21 of this control box 2 is judge whether to receive this notice (step S60) of losing heart that this microprocessing unit 11 transmits, if, then this microprocessor 21 controls this disappointing unit 22 and cuts out (step S62), controls this presser unit 23 simultaneously and this air bag 31 is pressurizeed (step S64). Owing to this disappointing unit 22 is main in order to the gas in this air bag 31 of venting, therefore before this step S64, this microprocessor 21 need to first cut out this disappointing unit 22, and this presser unit 23 could be made effectively to pressurize for this air bag 31.
After step S64, this microprocessor 21 judges whether this gas supply device 1 decommissions (step S66). If this gas supply device 1 not yet decommissions, then returning to this step S60, this microprocessor 21 continues to judge whether to receive this notice of losing heart that this gas supply device 1 transmits. Otherwise, if this gas supply device 1 decommissions, then this control box 2 decommissions (step S68) equally.
In the present embodiment, if this control box 2 does not receive this notice of losing heart that this microprocessing unit 11 transmits, then judge whether reach one the 3rd setting value (step S70) standby time. More specifically, this microprocessor 21 is in normal operation and the period not receiving this notice of losing heart, and is counted by this second enumerator, to confirm this above-mentioned standby time. If this standby time not yet reaches the 3rd setting value, then this microprocessor 21 continues to judge whether to receive this notice of losing heart, and continues to judge whether this standby time reaches the 3rd setting value.
If this standby time reaches the 3rd setting value, then this microprocessor 21 controls this disappointing unit 22 and opens (step S72), so as to the gas in this air bag 31 of venting. Specifically, this microprocessor 21 mainly controls to cut out after this disappointing unit 22 opens the of short duration time, and whereby, the portion gas in appropriateness this air bag 31 of venting, to adjust the degrees of expansion of this air bag 31. Consequently, it is possible to constriction produced by this this face shield 3 of user 4 prestowage can effectively be alleviated. After this step S72, the value of this second enumerator removed by this microprocessor 21, in order to recalculating this standby time.
After step S74, this microprocessor 21 judges whether this gas supply device 1 decommissions equally, judges whether to receive this notice of losing heart, and decommission when this gas supply device 1 decommissions when this gas supply device 1 not yet decommissions.
Next referring to Fig. 7, the 3rd the disappointing of specific embodiment for the present invention prevents flow chart. In the embodiment of Fig. 7, this control box 2 has this gas bleeder valve 22, and in the present embodiment, this gas bleeder valve 22 is to realize with a certain amount of gas bleeder valve. Being in that with the difference of this electromagnetic valve above-mentioned, the gas (such as venting 0.2cc per minute) in this quantitative gas bleeder valve meeting stably venting pipeline itself, not directly by the control of this microprocessor 21.
First, this microprocessor 21 of this control box 2 judges whether to receive this notice (step S80) of losing heart that this microprocessing unit 11 transmits, if so, then this microprocessor 21 controls this presser unit 23 this air bag 31 is pressurizeed (step S82). It is noted that this disappointing unit 22 owing to using in the present embodiment is quantitative gas bleeder valve, therefore before this step S82, this microprocessor 21 need not control this disappointing unit 22 and cut out.
After this step S82, this microprocessor 21 judges whether this gas supply device 1 decommissions, or whether reaches one the 4th setting value (step S84) pressing time. If this gas supply device 1 not yet decommissions, and this pressing time also not yet reaches the 4th setting value, then return to this step S80, and this microprocessor 21 continues to judge whether to receive this notice of losing heart that this gas supply device 1 transmits. Otherwise, if this gas supply device 1 decommissions, or reaching the 4th setting value this pressing time, then this control box 2 decommissions (step S86). It is noted that if this control box 2 is because reaching the 4th setting value this pressing time and decommissioning, then this control box 2 notifies this gas supply device 1 while decommissioning.
In the present embodiment, this microprocessor 21 is the period this air bag 31 pressurizeed in this presser unit 23, is counted by this second enumerator, to confirm this above-mentioned pressing time. If this pressing time not yet reaches the 4th setting value, then this microprocessor 21 continues to judge whether to receive this notice of losing heart, if continuing to receive this notice of losing heart, then controls this presser unit 23 persistent pressure. If this pressing time has reached the 4th setting value, then control this control box 2 and decommission.
If this control box 2 does not receive this notice of losing heart that this microprocessing unit 11 transmits, then judge whether a certain amount of disappointing time reaches one the 5th setting value (step S88). More specifically, this microprocessor 21 is in normal operation and the period not receiving this notice of losing heart, and is counted by one the 3rd enumerator (figure does not indicate), to confirm this above-mentioned quantitatively disappointing time. If this quantitatively loses heart, the time not yet reaches the 5th setting value, then this microprocessor 21 continues to judge whether to receive this notice of losing heart, and continues to judge whether this time of quantitatively losing heart reaches the 5th setting value.
If this quantitatively loses heart, time reaches the 5th setting value, then this microprocessor 21 controls this presser unit 23 this air bag 31 is pressurizeed (step S90), so as to increasing the gas in this air bag 31, makes this air bag 31 be expanded to suitable size. For example, the optimum of the gas flow in this air bag 31 can be 80cc to 90cc, and this disappointing unit 22 can quantitatively disappointing 0.2cc per minute. In this example, this microprocessor 21 initially controls this presser unit 23 and this air bag 31 is pressurizeed, make the gas flow in this air bag 31 reach 90cc, and calculate a working cycle (dutycycle) by the 3rd enumerator and the 5th setting value. Lose heart when this disappointing unit 22 stabilizes to this air bag 31, and when making the gas flow in this air bag 31 reduce to 80cc after this working cycle, this microprocessor 21 automatically controls this presser unit 23 and again pressurizes for this air bag 31, to make the gas flow in this air bag 31 revert to 90cc. Consequently, it is possible to the phase interworking of this disappointing unit 22 and this presser unit 23 can be passed through, make the gas flow in this air bag 31 can maintain in the scope of the best, allow this user 4 can obtain the comfort level of the best when this face shield 3 of prestowage whereby.
After this step S90, the value (step S92) of the 3rd enumerator removed by this microprocessor 21, quantitatively loses heart the time in order to recalculating this. After this step S92, this microprocessor 21 judges whether this gas supply device 1 decommissions (step S94). If this gas supply device 1 not yet decommissions, then returning to this step S80, this microprocessor 21 continues to judge whether to receive this notice of losing heart that this gas supply device 1 transmits, and continues to judge whether this time of quantitatively losing heart reaches the 5th setting value. Otherwise, if this gas supply device 1 decommissions, then this control box 2 decommissions (step S96) equally.
