Description
Technical field
The present invention relates to medical instruments field, particularly relate to a kind of irrigator EMC device.
Background technology
Electro Magnetic Compatibility, it is called for short EMC, be defined as " equipment and system in its electromagnetic environment can normal operation and not to environment in anything constitutes the ability of electromagnetic disturbance that can not bear ", this definition comprises the meaning of two aspects, first, this equipment should be able under certain electromagnetic environment normal operation, namely this equipment should possess certain electromagnetic immunity (EMS)；Second, other electronic products can not be produced excessive impact, i.e. electromagnetic disturbance (EMI) by the electromagnetic disturbance that this equipment self produces.Electromagnetic compatibility (EMC) is that electronic product disturbs size (EMI) and the Comprehensive Assessment of capacity of resisting disturbance (EMS) in electromagnetic field, is one of most important index of product quality, and the measurement of electromagnetic compatibility is made up of test site and test instrunment.
When undesirable voltage and current affects equipment performance, being referred to as there is electromagnetic interference, these voltage and currents can pass through conduction or electromagnetic field radiation and victim device is produced less desirable impact.Form electromagnetic interference and must be provided simultaneously with three factors: (1) electromagnetic interference source, i.e. " emitter "；(2) " receptor " that the interfering energy of this kind of type is sensitive；(3) energy is coupled to receptor from interference source, and makes the medium that systematic function substantially worsens, or claim coupling channel." emitter " refers to electromagnetic energy source, and " receptor " refers to the equipment that electromagnetic energy produces response.
Dividing from interference source, electromagnetic interference can be divided into natural disturbance source and artificial disturbance source.Natural disturbance source includes the sky noise that on the earth, thunderstorm, lightning produce everywhere, the cosmic noise in sunspot blast and the movable noise produced and the milky way galaxy.Artificial disturbance source is the electromagnetic interference produced by dynamo-electric or other Prosthesis, such as various radio transmitters；Industrial Scientific Medical radio-frequency apparatus；Motor, household electrical appliance, ligthing paraphernalia and similar electronic equipment；Information Technology Equipment；And static discharge and electromagnetic pulse etc..
Medical domain is had very big hazardness by electromagnetic interference, and main manifestations is:
(1) infringement Medical Equipment.Harm to electronic system, equipment, strong electromagnetic interference is likely to make sensitive electronic equipment damage because of overload.Breakdown reverse voltage between general silicon transistor emitter stage and base stage is 2～5V, very fragile, and its breakdown reverse voltage raises with temperature and declines.The peak voltage that electromagnetic interference causes can make certain some impurity concentration in emitter junction and collector junction increase, and causes transistor to puncture or internal short-circuit.The transistor worked after the match at strong radio-frequency electromagnetic can absorb enough energy, makes junction temperature exceed permission temperature rise and causes damaging.The infringement that electromagnetic interference causes also has: a) the losing of data in digital display circuit and data transmission procedure.B) the destruction of equipment, subsystem or system-level normal operation.C) work of medical treatment electronic equipment (such as: medical monitoring view, electrocardio pacemaker etc.) is not normal.
(2) it is detrimental to health.Electromagnetic radiation will cause biological effect once enter human cell tissue, i.e. local heat effect and non-thermal effect.For heat effect, along with being gradually increased of radio frequency incident power densities, may occur in which that blood flow is accelerated, the blood distribution local body temperature rising at less position, enzymatic activity reduction, protein denaturation, alteration in heart rate even Thermoregulation ability are suppressed, Local tissue damage is until death etc..The electromagnetic radiation of different frequency is to the extent of injury of human body different.To the radiation lower than 1GHz, skin histology is insensitive, and energy permeability is strong, is easily generated deep tissue and is heated and damages.Radiation to 1～3GHz, human body surface tissue and deep tissue all can absorb energy, as eyeball and inner tissue are very easily damaged.The heat effect of electromagnetic field can make human body temperature raise, and when human body exceedes normal body temperature, the requirement of metabolism and oxygen quickly increases, for instance temperature raises.And for non-thermal effect.Its impact is just much broader.Including to central nervous system's (such as bio electricity etc. to the metabolism of cerebral tissue, cerebral tissue), to hemic and immune systems, on cardiovascular system, on impact of reproductive system and fetal development etc..These impacts are not only reacted in individual level, organ level and are had influence on cell grade.
Therefore, the deterioration of electromagnetic environment, many-sided consequence, developing electromagnetic compatibility research can be caused, strengthen management of EMC, reduce electromagnetic disturbance, it is to avoid electromagnetic interference, is the task of top priority.Existing Medical Irrigator is generally made up of irrigator gun body and power supply, EMI harm ubiquity, the loss of data in digital display circuit with data transmission procedure of periphery medical equipment can be caused, cause the destruction at equipment, subsystem or system-level normal operation, may result in the work of medical treatment electronic equipment (such as medical monitoring view, electrocardio pacemaker etc.) not normal, therefore, the electromagnetic compatibility of Medical Irrigator product needs solution badly.
