Description
Technical field
The present invention relates to defibrillator, relate to particularly wearable external defibrillator.
Background technology
The whole world approximately has 1,750 ten thousand people to die from heart disease every year at present, accounts for 30% of whole death tolls; Although the survivor of annual heart attack and apoplexy has 2,000 ten thousand at least, wherein majority have very high recurrence and mortality risk.In case after heart attack, patient runs into the not normal risk of life-threatening cardiac rhythm to be increased.
The modal reason of sudden cardiac death is ventricular fibrillation, this is a kind of serious ventricular arrhythmia, make heart lose effective ejection function, do cardiac compression or other measures all can only extend the persistent period of quivering in chamber, temporary transient be important organ blood supply oxygen supply, recovers and can't the chamber of termination quiver the rhythm of the heart effectively poured into.So quiver and be only the most basic method of life of saving in the Quick stop chamber at the scene.
For arrhythmia, can select Drug therapy.But various research and experience show, the effect of drug administration is non-constant.
A kind of way for the treatment of outside medicine is defibrillation.Defibrillation is to make stronger pulse current eliminate arrhythmia by heart, makes it to recover the way of sinus rhythm.
Traditional defibrillator needs artificial cognition patient's cardiac rhythm, selects defibrillation mode and energy, therefore only has the medical worker through special training to use.
For this problem, automatic defibrillator has been proposed.Automatic defibrillator can detect patient's electrocardiosignal, and according to the electrocardiosignal automatic decision detected, carries out the opportunity of defibrillation action, and defibrillation mode and energy etc., and the people of training can use automatic defibrillator to give first aid to others a little.Therefore, usually in densely populated places such as school, airport, shopping centers, automatic defibrillator is set, makes it possible in time the cardiac be rescued.But prerequisite is to have other people can use this equipment, when judgement client need defibrillation by attachment of electrodes to suitable position and automatic defibrillator is operated, this is often unrealistic.In addition, traditional automatic defibrillator volume ratio is larger, is not suitable for carrying, and can not to the patient, monitor whenever and wherever possible and give first aid to.
For the shortcoming of traditional automatic defibrillator, implantable cardiac defibrillator (ICD) has been proposed.ICD is implanted in the subcutaneous of patient, is connected with heart by electric wire.ICD detects electrocardiosignal constantly, and the electrocardiosignal detected is analyzed.When according to analysis result, being judged as arrhythmia, heart is carried out to pulsed discharge, make patient's the rhythm of the heart recover normal.In the implanted patient body of ICD and carried by the patient, and without manual intervention, automatically monitoring patient's the rhythm of the heart and automatically discharge, is therefore very easily.But, need to perform the operation ICD is implanted in patient body, can bring misery to the patient, and ICD need to regularly replace battery, while changing battery, also can bring misery to the patient.In addition, be implanted in body and also can bring uncertain risk.This is all the conflict reasons of ICD of a lot of patients.
In order to alleviate simultaneously patient's misery in the situation that help automatically to carry out rhythm of the heart detection and defibrillation without other people, wearable defibrillator has been proposed.This wearable defibrillator is made into the form that vest is the same, wears for the patient.For example, so wearable defibrillator is disclosed in following patent documentation 1 and 2.
Patent documentation 1:US8140154
Patent documentation 2:US4928690
For example, this wearable defibrillator can comprise a plurality of core signal sensor electrodes (such as 4) of being attached to the patient chest abdominal part, be attached to patient's chest or a plurality of sparking electrodes at back (such as 2 or 3), be worn at main frame on patient's waist and corresponding wire etc., and main frame comprises controller, power supply, operation-interface etc.
Although this wearable defibrillator has facilitated patient's use largely, but there are some problems.For example, current wearable defibrillator components is various, particularly troublesome in the time of each the wearing.In addition, current wearable defibrillator components volume is still too huge, when pasting health and put on clothes after having dressed defibrillator, can seem too fat to move especially, and cause movable very inconvenient.This causes the patient to be unwilling to dress this defibrillator to a certain extent.
In addition, the existing defibrillator testing result that is based on electrocardiosignal starts the defibrillation electric discharge.But, in actual environment for use, due to the contact condition of sensor electrode and health, the electromagnetic interference in environment etc., often make in the signal detected and comprise interference component.Such interference component is difficult to eliminate, and makes ARR judgement produce error, in serious situation, can cause misoperation or be failure to actuate, and both of these case may be all fatal for the patient.

The specific embodiment
Below in conjunction with accompanying drawing, illustrative embodiments of the present invention is elaborated.What need statement is, the invention is not restricted to the embodiment of following explanation, and scope of the present invention only is defined by the claims.
The first embodiment
Fig. 1 is shown schematically in the using state of the wearable defibrillator of present embodiment.As shown in Figure 1, from the appearance, the wearable defibrillator of present embodiment comprises 2 parts of separating substantially, i.e. fuselage (according to circumstances, sometimes also referred to as housing) the 1 and first electrode slice 3.The first electrode slice 3 is made by metal material, is connected in fuselage 1 via wire 2.Fuselage 1 is worn on user (sometimes also referred to as the patient's) arm.
In fuselage (housing) 1, contain battery, core signal sensor 102, circuit for producing high voltage (high pressure generating unit) 103 and controller (control part) 104.Battery, as the working power of defibrillator, provides electric power to core signal sensor 102, circuit for producing high voltage 103 and controller 104 etc.
Circuit for producing high voltage 103 is for generation of the patient being carried out to the high voltage of electric defibrillation.Circuit for producing high voltage 103 can be any known structure, is not limited in this respect.In addition, the magnitude of voltage when the present invention carries out electric defibrillation for circuit for producing high voltage 103, discharge type etc. are not restriction also, can adopt any known form.For example, circuit for producing high voltage 103 can comprise transformator and high-voltage capacitor etc., via the gauge tap output HIGH voltage of IBGT or SCR formation.
Circuit for producing high voltage 103 has positive and negative two outfans.One of them outfan can be connected to the first electrode slice 3, and another outfan can be connected to the second electrode slice 4.
As can be seen here, the first electrode slice 3 and the second electrode slice 4 can optionally be connected to core signal sensor 102 or circuit for producing high voltage 103.Below to this, optionally connect and describe.
As shown in Figure 3, the wearable defibrillator of present embodiment has the first switch 111 between the first electrode slice 3 and core signal sensor 102 and circuit for producing high voltage 103, have second switch 112 between the second electrode slice 4 and core signal sensor 102 and circuit for producing high voltage 103.Switch 111 at one end has a contact, and this contact is connected with the first electrode slice 3.Switch 111 has two contacts at the other end, and one of them is connected with core signal sensor 102, and another is connected with an outfan of circuit for producing high voltage 103.Equally, switch 112 at one end has a contact, and this contact is connected with the second electrode slice 4.Switch 112 has two contacts at the other end, and one of them is connected with core signal sensor 102, and another is connected with another outfan of circuit for producing high voltage 103. Switch 111 and 112 is controlled by control part 104, and link, thereby at the first electrode slice 3 and the second electrode slice 4, be connected to respectively the state of core signal sensor 102, and the first electrode slice 3 and the second electrode slice 4 are connected to respectively between the state of circuit for producing high voltage 103 and switch.
In addition, for example bandage 5 can be designed as, when housing 1 is fixed on patient's arm, and its bottom surface, also namely the second electrode slice 4 is in the position for example, with the tremulous pulse (radial artery) of patient's arm relative.The scientist Patrick Reilly of U.S. Johns Hopkins University is (Applied bioelectricity:from electrical stimulation to electropathology in the bioelectric stimulation monograph, 1998Springer-Verlag New York, Inc) introduce the signal of telecommunication and can reduce resistance via the tremulous pulse transmission.By making the second electrode slice 4 be in the position for example, with the tremulous pulse (radial artery) of patient's arm relative, when carrying out electric defibrillation, electric current directly passes to cardiac muscle above by the tremulous pulse of upper arm, thereby has reduced the marginal value of myocardium electric shock, has so just further reduced the required energy that shocks by electricity.This is for by battery-driven wearable defibrillator, being even more important.
The wearable defibrillator of present embodiment carries out the action of electric defibrillation with in the past substantially identical based on the testing result of electrocardiosignal.Below only the special feature of present embodiment is described.
The wearable defibrillator of present embodiment has monitoring mode and these two kinds of mode of operations for the treatment of pattern.Controller 104 switches by switch 111 and 112 being controlled between these two kinds of mode of operations.Under monitoring mode, the first electrode slice 3 is connected with core signal sensor 102 respectively with the second electrode slice 4, and core signal sensor 102 carries out work.Under the treatment pattern, the first electrode slice 3 is connected with circuit for producing high voltage 103 respectively with the second electrode slice 4, and circuit for producing high voltage 103 carries out work.
After being switched on power supply, the wearable defibrillator of present embodiment works always.With reference to Fig. 4, after switching on power, enter step S401, controller 104 is set to monitoring mode, namely by gauge tap 111 and 112, the first electrode slice 3 is connected with core signal sensor 102 respectively with the second electrode slice 4, thereby the first electrode slice 3 and the second electrode slice 4 serve as respectively the detecting electrode of core signal sensor 102.After this, in step S402, core signal sensor 102 detects patient's electrocardiosignal constantly by certain time interval, the electrocardiosignal that 104 pairs of core signal sensors 102 of controller detect is carried out filtering and noise reduction, based on the electrocardiosignal after denoising, carry out waveforms detection, thereby whether analyze the rhythm of the heart not normal.In step S403, judge whether patient's the rhythm of the heart is not normal.Under being judged as the normal situation of the rhythm of the heart (in step S403 no), flow process is back to step S402, continues the determination and analysis of electrocardiosignal.In step S403, be judged as in ARR situation (being in step S403), flow process enters step S404, and controller is set as the treatment pattern by defibrillator.Now, 104 pairs of switches of controller 111 and 112 are controlled, disconnect being connected of the first electrode slice 3 and the second electrode slice 4 and core signal sensor 102, stop the work of core signal sensor 102, and the first electrode slice 3 is connected with two lead-out terminals of circuit for producing high voltage 103 respectively with the second electrode slice 4, circuit for producing high voltage 103 is started working.Then, in step S405, control circuit for producing high voltage 103 and carry out high-voltage charging, apply by the first electrode slice 3 and 4 couples of patients of the second electrode slice the voltage produced.Subsequently, through the regular hour, for example 1-2 is after second, flow process is back to step S401, controller 104 returns the defibrillator setting to monitoring mode, namely by gauge tap 111 and 112, the first electrode slice 3 is connected respectively with core signal sensor 102 with the second electrode slice 4, makes core signal sensor 102 carry out work.Then repeat above-mentioned processing.
Like this, after carrying out electric defibrillation, normal if patient's the rhythm of the heart also recovers, can automatically carry out defibrillation again.
According to above-mentioned the first embodiment of the present invention, defibrillator only has two electrodes, and these two electrodes are also used as the detecting electrode of electrocardiosignal and the sparking electrode of electric defibrillation, and the fuselage of one of them electrode and defibrillator forms as one.Like this, as the parts of split, just only have 2, i.e. the first electrode slice and housing.When dressing, only the first electrode slice need be attached to the shirtfront of user, housing is fixed to arm, namely completed wearing.Whole wearing process is very simple, also is not easy to make mistakes.In addition, because parts reduce, overall volume also greatly reduces, and user can not seem yet after having dressed this defibrillator too fat to move, can not cause on the action of user too large impact.Due to the part count reduced, also correspondingly reduced the cost of defibrillator in addition.
The second embodiment
Below the second embodiment of the present invention is described.Except the part of following explanation, the other side of the wearable defibrillator of the second embodiment is identical with the wearable defibrillator of the first embodiment.
The wearable defibrillator of the second embodiment was specially adapted to the cardiac of tachycardia medical history.
Two kinds of common life-threatening tachycardias comprise ventricular tachycardia and ventricular fibrillation.Ventricular tachycardia is a kind of cardiac rhythm fast, originates from the signal of telecommunication that ventricle causes.Ventricular tachycardia can reduce heart and blood transport, causes blood pressure low.Ventricular tachycardia also can develop into more serious situation, i.e. ventricular fibrillation.
Ventricular fibrillation refers to that quick, unordered excitement occurs ventricle, is that cardiac muscle by ventricle produces irregular contraction and causes.Ventricular fibrillation is modal arrhythmia, if this arrhythmia continues to surpass several seconds, it may degenerate to asystole, this situation can cause cardiogenic shock and blood circulation to stop, thereby cause sudden cardiac death within short a few minutes, if the patient can not recover in time, will produce irreversible brain injury.
When tachyarrhythmia occurred, ventricle can not produce effective blood flow, thereby there is no cardiac output, can deteriorate into speed usually be greater than 180 per minute, thereby cause without pulse frequency, this is the typical characteristic of tachyarrhythmia.
As previously described, due to the contact condition of electrode and health, on every side electromagnetic interference etc., in the electrocardio detection signal, often contain interference component, and be difficult to remove fully the impact of interference component, this causes sometimes judging exactly that heart beating is not normal, thereby causes without judgement or misoperation.
Present embodiment, on the basis of the first embodiment, has been appended pulse transducer.This pulse transducer is housed in housing 1, and the one end be exposed to housing outer and with patient's Body contact, this end exposed is roughly concordant with the outer surface of the second electrode slice 4.For example, can form respectively and the corresponding opening of this pulse transducer on housing 1 and the second electrode slice 4, pulse transducer exposes by this opening.Certainly, between the sidewall of pulse transducer and this opening, sealing member can be set, to keep the sealing in housing 1.In addition, when defibrillator was clothed to patient's arm, this pulse transducer was relative with the vessel position of patient's arm.
For the not restriction of type of this pulse transducer, as long as can detect patient's pulse.For example, can adopts pressure sensor, detect the variation of the pressure of blood vessel along with pulse.Also can adopt infrared sensor, the infrared ray of some wavelength is very responsive to the variation of the volumetric blood in blood vessel, therefore can utilize this infrared sensor to irradiate infrared ray and receive the infrared ray returned to blood vessel and detect the capacity of blood vessel variation, thereby realize the detection of pulse.The detection signal of pulse transducer is sent to controller 104.
Below with reference to Fig. 5, the work of the defibrillator of present embodiment is described.
After being switched on power supply, the wearable defibrillator of present embodiment works always.With reference to Fig. 5, after switching on power, enter step S401, controller 104 is set to monitoring mode, namely by gauge tap 111 and 112, the first electrode slice 3 is connected with core signal sensor 102 respectively with the second electrode slice 4, thereby the first electrode slice 3 and the second electrode slice 4 serve as respectively the detecting electrode of core signal sensor 102.After this, in step S402, core signal sensor 102 detects patient's electrocardiosignal constantly by certain time interval, the electrocardiosignal that 104 pairs of core signal sensors 102 of controller detect is carried out filtering and noise reduction, based on the electrocardiosignal after denoising, carry out waveforms detection, thereby whether analyze the rhythm of the heart not normal.In step S403, judge whether patient's the rhythm of the heart is not normal.Under being judged as the normal situation of the rhythm of the heart (in step S403 no), flow process is back to step S402, continues the determination and analysis of electrocardiosignal.In step S403, be judged as in ARR situation (being in step S403), flow process enters step S4031, and controller 104 judges whether patient's pulse is not normal, and namely whether judgement and pulse are greater than predetermined value, perhaps whether pulse is irregular, or whether there is no pulse.Here, can adopt any known method to judge that whether pulse is normal, repeats no more here.In addition, pulse transducer can be worked always after defibrillator energising, also can start according to the control of controller 104, for example, in the situation that the "Yes" that judgment result is that of step S403 is just started working, and quits work after step S404.Can reduce the power consumption of defibrillator like this.
Under being judged as the normal situation of pulse (in step S4031 no), flow process is back to step S402, continues the determination and analysis of electrocardiosignal.In the situation that in step S4031, be judged as pulse not normal (being in step S4031), flow process enters step S404, and controller 104 is set as the treatment pattern by defibrillator.Now, 104 pairs of switches of controller 111 and 112 are controlled, disconnect being connected of the first electrode slice 3 and the second electrode slice 4 and core signal sensor 102, stop the work of core signal sensor 102, and the first electrode slice 3 is connected with two lead-out terminals of circuit for producing high voltage 103 respectively with the second electrode slice 4, circuit for producing high voltage 103 is started working.Then, in step S405, control circuit for producing high voltage 103 and carry out high-voltage charging, apply by the first electrode slice 3 and 4 couples of patients of the second electrode slice the voltage produced.Subsequently, through the regular hour, for example 1-2 is after second, flow process is back to step S401, controller 104 returns the defibrillator setting to monitoring mode, namely by gauge tap 111 and 112, the first electrode slice 3 is connected respectively with core signal sensor 102 with the second electrode slice 4, makes core signal sensor 102 carry out work.Then repeat above-mentioned processing.
Like this, after carrying out electric defibrillation, normal if patient's the rhythm of the heart also recovers, can automatically carry out defibrillation again.
Present embodiment, on the basis that monitors electrocardiosignal, monitors patient's pulse simultaneously.Like this, except the advantage of the first embodiment, present embodiment can be avoided the impact of external interference, has greatly improved the reliability of defibrillator, especially the most effective to the patient of ventricular tachycardia.
