In above-mentioned steps 101 it is understood that in order to carry out electro photoluminescence assisted respiartion, need to make electro photoluminescence and reality Respiratory is mutually in step.Therefore the timing in order to determine electrical stimulation signal, need the mesh before applying electro photoluminescence by envisioning Mark respiratory determine its time-parameters (i.e. the time-parameters of target respiratory refer specifically to for determine electrical stimulation signal when The parameter of sequence).Specifically, the time-parameters of target respiratory acquired in any time may include first time air-breathing and open Moment beginning, start time of exhaling for the first time, air-breathing start time, start time of exhaling next time, this air-breathing terminate next time When respiratory cycle when moment, this exhale finish time and target respiratory are in mechanical periodicity, respiratory rate, air-breathing Between, the end inspiratory pause time, expiratory duration it is any one or more, those skilled in the art can choose according to actual needs (there are the parameters of conversion relation without all including).And the selection example as a kind of minimum requirements, in no output diaphragm mind Through stimulus signal or at the time of abdominal muscle stimulus signal, acquired time-parameters should at least be enough to determine the diaphragm mind of next output At the beginning of stimulus signal or abdominal muscle stimulus signal;And exporting diaphragm nerve stimulation signal or abdominal muscle stimulus signal Moment, acquired time-parameters should at least be enough to determine the diaphragm nerve stimulation signal or abdominal muscle stimulus signal currently exported Finish time.

It will also be appreciated that after the time-parameters of target respiratory required for acquiring at any time, At the beginning of just can at least determining diaphragm nerve stimulation signal or abdominal muscle stimulus signal to be output, or exporting The finish time of diaphragm nerve stimulation signal or abdominal muscle stimulus signal, thus the method for the embodiment of the present invention can on the whole according to The mode configured cooperates practical respiratory to apply electro photoluminescence.Certainly, the time-parameters of target respiratory may come from Pre-stored configuration data can be from the electric signal collected by practical respiratory.

A kind of time-parameters as target respiratory may come from the specific example of pre-stored configuration data, Above-mentioned steps 101 can specifically include following processes: target respiratory being pre-configured with according to periodic respiratory, is obtained Its time parameter is taken, specifically includes: inspiratory duration (0.5s~5s), end inspiratory pause time (0s~2s), expiratory duration (0.5s ~5s), respiratory rate (2~25 beats/min), electric stimulating time (1~30 minute) and start time (act by user key-press It determines).To which above-mentioned steps 102 specifically include following processes: in start time, to diaphram stimulating electrode output nervus phrenicus thorn Energizing signal (current signal), design parameter can be in 0~100mA of current strength, 20~100Hz of pulse frequency, pulse widths 100 It is pre-configured in the range of~500us.Start time after the time span of an inspiratory duration (0.5s~5s), stop to Diaphram stimulating electrode exports diaphragm nerve stimulation signal.Using an end inspiratory pause time (0s~2s) time span it Afterwards, start to export abdominal muscle stimulus signal to abdominal muscle stimulating electrode, and continue the time span of an expiratory duration (0.5s~5s) After stop.Hereafter, it (by respiratory rate, inspiratory duration, the end inspiratory pause time, exhales using an end-tidal time out Time determines) after, start the process for exporting diaphragm nerve stimulation signal in next respiratory cycle to diaphram stimulating electrode, successively class It pushes away, terminates after reaching the time span of electric stimulating time (1~30 minute).As can be seen that being based on pre-stored configuration The electro photoluminescence Respiration assistance under user configuration may be implemented in data, the method for this example, i.e. user is defeated by modes such as operation interfaces Enter configuration data, and carries out the process of electro photoluminescence Respiration assistance using the configuration data.

And as the time-parameters of target respiratory from the electric signal collected by practical respiratory A kind of example, Fig. 2 shows the specific steps processes of its time-parameters for obtaining target respiratory.Referring to fig. 2, in this example It states step 101: obtaining the time-parameters of target respiratory, specifically include:

Step 101a: instruction message is persistently received at synchronized with breath port;

Step 101b: mark, air-breathing end of identification are started according to the air-breathing that each described instruction message is included, exhales and opens Begin mark or expiration end of identification and each described instruction message receiving time, determine the target respiratory when Between parameter.

It is understood that above-metioned instruction message can be generated by external equipment, such as can be by wear-type breath detector Breath state by detecting wearer generates, and is transmitted to above-mentioned synchronized with breath port by data bus connection.As one kind Example, above-metioned instruction message can be specially the data of 4 bytes, and the above-mentioned air-breathing of preceding 4 receivings starts in 8 data of head byte Mark (0b1100), air-breathing end of identification (0b0011), exhaling starts to identify (0b1010) or expiration end of identification (0b0101), 5th, 6 is used to indicate the length (for example 0b11 indicates that there are also 3 bytes after head byte) of instruction message, and the 7th is left a blank, the 8th Position is used as parity check bit.

Above-mentioned steps 101a, step 101b and step 102 form the electro photoluminescence auxiliary under synchronized with breath port controlling as a result, Respiratory specifically includes: when the instruction message received at synchronized with breath port includes that air-breathing starts mark, by the instruction The receiving time of message is determined as air-breathing start time (time-parameters of the target respiratory obtained at this time) next time, from And start to export diaphragm nerve stimulation signal at the moment;The instruction message received at synchronized with breath port terminates comprising air-breathing When mark, the receiving time of the instruction message is determined as this air-breathing finish time (target respiratory obtained at this time Time-parameters), thus the moment stop output diaphragm nerve stimulation signal;The instruction received at synchronized with breath port disappears When breath starts mark comprising exhaling, the receiving time of the instruction message is determined as exhaling start time next time and (is obtained at this time The time-parameters of the target respiratory taken), to start to export abdominal muscle stimulus signal at the moment;At synchronized with breath port When the instruction message received includes expiration end of identification, at the end of the receiving time of the instruction message is determined as this expiration It carves (time-parameters of the target respiratory obtained at this time), to stop output abdominal muscle stimulus signal at the moment.Pass through Above description is it is understood that above-mentioned steps 101a, step 101b and step 102 are executing sequentially not according to stringent Chronological order.

As can be seen that being based on above-mentioned steps 101a and step 101b, the method for this example can cooperate device for detecting respiratory real Now the external control of electro photoluminescence Respiration assistance is realized with the synchronization of practical respiratory, or cooperation peripheral control unit, thus Richer functional mode can be provided to user, and other devices can be cooperated to realize the expansibility of height, optimize and use Family experience.

Step 101c: for can not as receive instruction message obtained from the target respiratory time-parameters, It is obtained from pre-stored configuration data.

Based on above-mentioned steps 101c, it is different that the method for this example can alleviate output caused by shortage of data or error in data Often.For example, when the instruction message received at above-mentioned synchronized with breath port includes that air-breathing starts mark, although can be straight Connecting acquisition, air-breathing start time exports diaphragm nerve stimulation signal next time, but the diaphragm nerve stimulation signal it is lasting when Between the time-parameters that are but missing from of corresponding inspiratory duration.It, can be according to pre-stored configuration data in step 101c In acquire inspiratory duration (0.5s~5s), thus guarantee the diaphragm nerve stimulation signal will not the duration it is too long and occur different Often.

Moreover, be based on above-mentioned steps 101c, when the method for this example can fail in synchronized with breath port or is abnormal automatically with The time-parameters of target respiratory carry out electro photoluminescence Respiration assistance from the mode of pre-stored configuration data, thus Two kinds of operating modes are combined, the promotion of reliability and user experience is facilitated.

On the other hand, it is real to generally use the voltage-type circuit comprising transformer for external diaphragm pacemaker in the prior art It is existing, so that product overall volume is larger.To overcome this defect, in the method for any one of the above electro photoluminescence assisted respiartion, diaphragm Nerve stimulation signal and/or abdominal muscle stimulus signal can be generated by the current source circuit under Digital Signals.Based on this, number is believed Number processing circuit and current source circuit can use integrated chip and/or the mode of circuit board real with lesser volume It is existing, thus help to reduce small product size, reduce cost of manufacture.

In addition, method can further include not attached on the basis of the method for any one of the above electro photoluminescence assisted respiartion Following step shown in figure:

Step 103: the size of the output electric current of the diaphragm nerve stimulation signal and/or the abdominal muscle stimulus signal is detected, To generate electrode delamination indication signal when size of current is lower than preset value.

Based on this, principle of the method for this example using human body resistance much smaller than air resistance carries out the size of output circuit Detection (i.e. electrode delamination when, the resistance of positive and negative interpolar mostlys come from air, thus there are the upper limits for size of current, according to this can be with Predefine above-mentioned preset value), and effective detection to electrode delamination situation is realized according to this, and then can be carried out to electrode delamination Corresponding actions facilitate the promotion of reliability and user experience.For example, electrode delamination indication signal can connect to electrode Fall off indicator light, to prompt user's electrode abnormal;Moreover, electrode delamination indication signal can connect to master controller, to stop The output of electrical stimulation signal.

Based on same inventive concept, Fig. 3 is a kind of device of electro photoluminescence assisted respiartion in one embodiment of the invention Structural block diagram.Referring to Fig. 3, which includes:

Module 31 is obtained, for obtaining the time-parameters of target respiratory;
