Description
Technical field
The present invention relates to the anaesthesia depth monitor of a kind of many monitoring indexes, belong to technical field of medical instruments.
Background technology
In art, depth of anesthesia accurately monitors and judges that having become clinical anesthesia doctor shows great attention to and urgently to be resolved hurrily difficult problem.General anesthesia is a kind of special and the state of complexity, including tranquilizing soporific, amnesia, analgesia, stress suppress and the many factors such as of flaccid muscles, and the overall process gone through general anesthesia induction, maintain and revive, each through using anaesthetic to control in whole process.Different modus operandis, different crowd and art moderate stimulation in various degree are also different to anaesthetic reactivity.The depth of anesthesia that anaesthetic consumption deficiency causes is excessively shallow, it is easy to causes the untoward reaction such as hemodynamics fluctuation, intraoperative diagnosis and body move, makes operation to be smoothed out；Anaesthetic is excessive, and anaesthetizing of causing is deep then in interior vital organ function, respiratory system, blood circulation is occurred serious suppression, and hypoxic-ischemic, serious may result in patient's injury of brain function, threat to life.Therefore, in art, anesthesia depth monitoring not only improves control anesthesia quality, and available minimum anaesthetic reaches the anaesthetic effect of the best again, shortens postoperative recovery time.
Presently the most successfully depth of anesthesia monitoring method is BIS(BIS Propofol-targeted, bispectralindex), this method designs according to human nerve's physiological characteristics, it is possible to reaction patient realizes disappearance and recovery situation rapidly, has good advantage as anesthesia depth monitoring index.
But shortcoming the most prominent for BIS is its threshold value to be not individually present when anaesthetic use in conjunction, during different drug combination, BIS value is identical, and not represent depth of anesthesia identical, and different patients all can change at different anesthesia stage BIS value.Furthermore, BIS value, by the impact of many factors, as esmolol, ectogenic epinephrine can make BIS value raise, affects the actual value of depth of anesthesia, and nonetheless, BIS value still be can yet be regarded as one and reflected cerebral cortex function, reflects the good index of depth of anesthesia.But, BIS value is still not clear in situation of change and the mechanism thereof of the different anaesthetic of Different Individual application, and BIS is not suitable for those patients that can not make a response, therefore be presently required and take multiple means combined monitoring depth of anesthesia, each means monitoring result can be mutually authenticated, it is ensured that the anesthetis consumption of input is applicable to the required metering of Different Individual.
Summary of the invention
The technical problem to be solved is, there is provided a kind of monitoring index many, individual parameter differences can be revised, different acquisition module can be selected according to the actual demand of different patients, the monitoring result of each acquisition module can be mutually authenticated, it is ensured that the anesthetis consumption of input is applicable to the anaesthesia depth monitor of the required metering of Different Individual.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of anaesthesia depth monitor of many monitoring indexes, it is characterized in that, including acquisition module, the outfan of described acquisition module is connected with the input of amplification module, the outfan of described amplification module is connected with the input of denoising module, the described outfan of denoising module is connected with the input of modular converter, the outfan of described modular converter is connected with the input of MCU, the input of described MCU is also connected with the outfan of analogue simulation module, the input of described analogue simulation module is connected with individual variation parameter input module, the outfan of described MCU is connected with display module and injection module respectively；Described acquisition module includes at least two in the dynamic monitoring modular of brain electric data collecting electrode slice, auditory evoked potential acquisition electrode sheet, electrocardio-data collection electrode slice, non-invasive blood pressure acquisition module, body temperature acquisition module, pulse collection module, oxygen saturation monitor module, monitoring of respiration module and eye.
Described injection module is microsyringe, and the heap(ed) capacity of described microsyringe is 10 μ L.
The dynamic monitoring modular of described eye includes eye tracker.
Described brain electric data collecting electrode slice is bilateral cerebral electricity double frequency acquisition electrode sheet.
Described analogue simulation module includes individual variation correcting module.
Described display module includes LED display.
Individual variation parameter input module includes anesthetis kind input submodule, operation selection submodule, patient age input submodule, weight in patients input submodule and patient's premedicate input submodule.
Described anesthetis kind input submodule, operation selection submodule, patient age input submodule, weight in patients input submodule and patient's premedicate input submodule all include keyboard.
Analogue simulation module is single-chip microcomputer.
The setting of individual variation parameter input module, it is simple to judge the actually required anesthetis consumption of patient more accurately, as brain electric data collecting electrode slice is used for exporting BIS value, BIS value 100, waking state；BIS value 0, entirely without brain electrical acti state (cerebral cortex suppression), it is considered that BIS value is normal condition 85 ~ 100；65 ~ 85 is sedation；40 ~ 65 is narcotism；< 40 is likely to present outburst to be suppressed.And BIS value is by the impact of many factors, as esmolol, ectogenic epinephrine can make BIS value raise, affect the actual value of depth of anesthesia, therefore patient's premedicate input submodule need to be set, it is considered to the premedicate impact on BIS value.
The degree of association of anesthetis kind is also differed by different acquisition module, and the sedation depth produced such as BIS and most of anaesthetics has dependency.In intravenous anesthetics, the depth of anesthesia of propofol is fabulous with BIS value dependency, can the simple propofol degree of depth of accurate measurements.BIS is good with the inhaled concentration dependency of sevoflurane, desflurane, and when using Sevoflurane, BIS Depth of Anesthesia is reliable.But the research of isoflurane is found, BIS and isoflurane inhaled concentration non-correlation, it is impossible to the depth of anesthesia that monitoring isoflurane sucks, therefore different acquisition modules need to be selected to be monitored according to different anesthetis kinds.
Patient's all ages and classes, different body constitution, different sexes, different weight and the anesthetis consumption needed for different modus operandi are all different, therefore need each influence factor of comprehensive consideration.
BIS is relevant with the tranquilizing soporific degree in anesthesia, and it is the good index that a monitoring is calm；And AEP(auditory evoked potential, auditoryevokedpotentials) it is provided that many-sided information such as operation stimulation, analgesia, tranquilizing soporific.When, after a large amount of use analgesic, BIS is difficult to predictor and moves, and in this case, only AEP could reflect depth of anesthesia, it was predicted that body moves and intraoperative diagnosis comprehensively.But the inapplicable deafness patient of AEP.
The dynamic monitoring modular of eye can monitor the depth of anesthesia of patient according to rapid eye movement and SEM, but the dynamic monitoring modular of eye is not suitable for schizophrenia, depression, mania, bipolar disorders, obsession, anxiety neurosis, all kinds of neurosis such as neurasthenia and somatization disorder, cerebral organic psychosis, psychoactive drug substance (such as ethanol) caused by mental disorder, and stress-related disorder etc..
The anaesthesia depth monitor of a kind of many monitoring indexes provided by the invention, the setting of various monitoring measures, applicable at least two acquisition module can be selected according to the Different Individual situation of patient, the monitoring result of at least two acquisition module selected can be mutually authenticated, make monitoring result accurate, the depth of anesthesia of patient can be guarded, it is ensured that anesthetis consumption is accurate；The setting of analogue simulation module and individual variation parameter input module, it is achieved that individual parameter differences can be revised, and according to individual instances, the error of monitoring result Yu actual value can be modified, it is ensured that anesthetis consumption is accurate；The setting of the dynamic monitoring modular of eye, can the depth of anesthesia of patient anyway directly perceived, the evaluation for patient's depth of anesthesia has clinical meaning.
