Energy-absorbing power and cough ability, also help the comfort increasing user.
It is understood that in order to carry out electricity irritation assisted respiartion, need to make electricity irritation with actual in above-mentioned steps 101
Respiratory is mutually in step.Therefore to determine the sequential of electrical stimulation signal, needed before applying electricity irritation by the mesh envisioned
Mark respiratory determine its time-parameters (i.e. the time-parameters of target respiratory refer specifically to for determine electrical stimulation signal time
The parameter of sequence).Specifically, the time-parameters of the target respiratory acquired in any time can comprise for the first time air-breathing and opens
Moment, for the first time exhale start time, next time air-breathing start time, next time exhale start time, this air-breathing of beginning terminates
Moment, this exhales finish time, and when breathing cycle when target respiratory is mechanical periodicity, respiratory frequency, air-breathing
Between, the end inspiratory pause time, expiratory duration any one or more, those skilled in the art can choose according to actual needs
(there is the parameter of conversion relation without all comprising).And as the example of choosing of a kind of minimum requirements, do not exporting diaphragm god
Through stimulus signal or the moment of abdominal muscle stimulus signal, acquired time-parameters should at least be enough to determine the diaphragm god of next output
Through stimulus signal or the start time of abdominal muscle stimulus signal；And exporting diaphragm nerve stimulation signal or abdominal muscle stimulus signal
In the moment, acquired time-parameters should at least be enough to determine the diaphragm nerve stimulation signal currently exported or abdominal muscle stimulus signal
Finish time.
After will also be appreciated that the time-parameters acquiring required target respiratory at any time,
The most at least may determine that diaphragm nerve stimulation signal to be exported or the start time of abdominal muscle stimulus signal, or exporting
Diaphragm nerve stimulation signal or the finish time of abdominal muscle stimulus signal, thus the method for the embodiment of the present invention can on the whole according to
The mode configured coordinates actual respiratory to apply electricity irritation.Certainly, the time-parameters of target respiratory may come from
The configuration data prestored, it is also possible to come from the signal of telecommunication collected by actual respiratory.
Time-parameters as a kind of target respiratory may come from the concrete example of the configuration data prestored,
Above-mentioned steps 101 can specifically include following process: is pre-configured with according to periodic respiratory by target respiratory, obtains
Take its time parameter, specifically comprise: inspiratory duration (0.5s～5s), end inspiratory pause time (0s～2s), expiratory duration (0.5s
～5s), respiratory frequency (2～25 beats/min), electric stimulating time (1～30 minute) and start time be (by user key-press action
Determine).Thus, above-mentioned steps 102 specifically includes following process: in start time, to diaphram stimulating electrode output phrenic nerves thorn
Energizing signal (current signal), its design parameter can be in current intensity 0～100mA, pulse frequency 20～100Hz, pulse width 100
～be pre-configured with in the range of 500us.Start time after the time span of an inspiratory duration (0.5s～5s), stop to
Diaphram stimulating electrode output diaphragm nerve stimulation signal.Again through an end inspiratory pause time (0s～2s) time span it
After, start to export abdominal muscle stimulus signal to abdominal muscle stimulating electrode, and continue the time span of an expiratory duration (0.5s～5s)
Rear stopping.Hereafter, then through an end-tidal time out (by respiratory frequency, inspiratory duration, end inspiratory pause time, expiration
Time determines) after, start the process to diaphram stimulating electrode output diaphragm nerve stimulation signal, class successively in the next breathing cycle
Push away, until it reaches terminate after the time span of electric stimulating time (1～30 minute).It can be seen that based on the configuration prestored
Data, it is defeated by modes such as operation interfaces that the method for this example can realize the electricity irritation Respiration assistance under user configures, i.e. user
Enter and configure data, and use these configuration data to carry out the process of electricity irritation Respiration assistance.
And the signal of telecommunication that collected by actual respiratory is come from as the time-parameters of target respiratory
A kind of example, Fig. 2 shows that it obtains the concrete steps flow process of the time-parameters of target respiratory.See in Fig. 2, this example
State step 101: obtain the time-parameters of target respiratory, specifically include:
Step 101a: persistently receive instruction message in synchronized with breath port；
Step 101b: the air-breathing comprised according to each described instruction message starts mark, air-breathing terminates mark, expiration is opened
The mark that begins or exhale and terminate mark, and reception time of each described instruction message, determine described target respiratory time
Between parameter.
It is understood that above-mentioned instruction message can be generated by external equipment, such as can be by wear-type breath detector
Generated by the breath state of detection wearer, and by data bus connection transmission to above-mentioned synchronized with breath port.As one
Example, above-mentioned instruction message can be specially the data of 4 bytes, and in 8 bit data of head byte, front 4 above-mentioned air-breathings of receiving start
Mark (0b1100), air-breathing terminate to identify (0b0011), expiration starts to identify (0b1010) or expiration terminates mark (0b0101),
5th, 6 length (such as 0b11 also has 3 bytes after representing a byte) being used for representing instruction message, leave a blank for the 7th, and the 8th
Position is as parity check bit.
Thus, the electricity irritation auxiliary under above-mentioned steps 101a, step 101b and step 102 form synchronized with breath port controlling
Respiratory, specifically includes: the instruction message received when synchronized with breath port comprises air-breathing when starting to identify, by this instruction
The reception time of message is defined as air-breathing start time (time-parameters of the target respiratory the most now obtained) next time, from
And start to export diaphragm nerve stimulation signal in this moment；The instruction message received when synchronized with breath port comprises air-breathing to be terminated
During mark, is defined as this air-breathing finish time (target respiratory the most now obtained the reception time of this instruction message
Time-parameters), thus this moment stop output diaphragm nerve stimulation signal；The instruction received when synchronized with breath port disappears
Breath comprises expiration when starting to identify, and is defined as exhaling start time (the most now obtaining by the reception time of this instruction message next time
The time-parameters of the target respiratory taken), thus start to export abdominal muscle stimulus signal in this moment；When synchronized with breath port
When the instruction message received comprises expiration end mark, at the end of the reception time of this instruction message is defined as this expiration
Carve (time-parameters of the target respiratory the most now obtained), thus stop output abdominal muscle stimulus signal in this moment.Pass through
Described above is not it is understood that above-mentioned steps 101a, step 101b and step 102 have according to strict on execution sequence
Time order and function order.
It can be seen that based on above-mentioned steps 101a and step 101b, the method for this example can coordinate device for detecting respiratory real
Now with the synchronization of actual respiratory, or peripheral control unit is coordinated to realize the external control of electricity irritation Respiration assistance, thus
More rich functional mode can be provided, it is possible to coordinate other devices to realize the expansibility of height, optimize and use to user
Family is experienced.
Further, on the basis of the example method, above-mentioned steps 101 can be made: obtain the time of target respiratory
Parameter, also includes step not shown in FIG. 2:
Step 101c: the time-parameters of the described target respiratory for obtaining by receiving instruction message,
Obtain from the configuration data prestored.
Based on above-mentioned steps 101c, the output that the method for this example can alleviate shortage of data or error in data is caused is different
Often.For example, the instruction message received in above-mentioned synchronized with breath port comprises air-breathing when starting to identify, although Ke Yizhi
Connected and obtain air-breathing start time next time and export diaphragm nerve stimulation signal, but during this diaphragm nerve stimulation signal lasting
The time-parameters that inspiratory duration corresponding between is but missing from.In step 101c, can be according to the configuration data prestored
In acquire inspiratory duration (0.5s～5s), thus ensure this diaphragm nerve stimulation signal will not the persistent period long and occur different
Often.
And, based on above-mentioned steps 101c, the method for this example can when synchronized with breath port lost efficacy or is abnormal automatically with
The time-parameters of target respiratory comes from the mode of the configuration data prestored to carry out electricity irritation Respiration assistance, thus
Two kinds of mode of operations are combined, contributes to the lifting of reliability and Consumer's Experience.
On the other hand, external diaphragm pacemaker of the prior art generally uses the voltage-type circuit comprising transformator real
Existing so that product overall volume is bigger.For overcoming this defect, in the method for any one electricity irritation assisted respiartion above-mentioned, diaphragm
Nerve stimulation signal and/or abdominal muscle stimulus signal can be generated by the current source circuit under Digital Signals.Based on this, numeral is believed
Number process circuit and current source circuit all can be real with less volume in the way of using integrated chip and/or circuit board
Existing, thus help in reduction small product size, reduce cost of manufacture.
Additionally, on the basis of the method for any one electricity irritation assisted respiartion above-mentioned, method can also include not attached
Following step shown in figure:
Step 103: detect the size of the output electric current of described diaphragm nerve stimulation signal and/or described abdominal muscle stimulus signal,
To generate electrode delamination indication signal when size of current is less than preset value.
Based on this, the size of output circuit is carried out by the principle that the method for this example utilizes human body resistance to be much smaller than air resistance
(i.e. during electrode delamination, the resistance of positive and negative interpolar mostlys come from air, thus size of current exists the upper limit, the most permissible in detection
Predetermined above-mentioned preset value), and realize the effective detection to electrode delamination situation according to this, and then electrode delamination can be carried out
Corresponding actions, contributes to the lifting of reliability and Consumer's Experience.For example, electrode delamination indication signal can be connected to electrode
Come off display lamp, to point out user's electrode abnormal；And, electrode delamination indication signal can be connected to master controller, to stop
The output of electrical stimulation signal.
