Description

Gas sensing surgery device and using method
Technical field
Present invention relates in general to electro medical device, more particularly, to be operable as identify gas any electrically Medical treatment device.
Background technology
Medical field is always sought to improve the progress of quality and patient care.Many during these are progressive relates to electronics dress Put the use with equipment.Many in these devices and equipment is in surgical operation or diagnosis are arranged.Because from this The electric charge of a little devices and energy launch can fire hazard and the blast of local, so this in medical domain for suffering from Person, doctor, hospital and other be the most debatable.It practice, food and drug administration (FDA) Estimate that the U.S. occurs about 600 surgical operations to catch fire every year.These blast in many affect traumaticly patient and / or doctor, this causes disfeaturing, scabbing and other injuries.They also make medical facilities and doctor face civil liability.
For making these fire or burning occur, it is necessary to meet three requirements (also known as fire triangle).These requirements include Igniting (energy or thermal source), fuels sources and oxidizer.During medical procedure, commonly used electro medical device. These medical treatment devices (such as electronic surgery unit (ESU) (such as, cautery, galvanothermotherapy machine, laser Device, ultrasonic, optical fiber source and other)) emitted energy at their use point, thus carry for fire or burning For " igniting ".Specifically, ESU often produces spark at their use point, or causes and be enough to cause burning Heat." fuels sources " run into during surgical procedures include from before process to surgical site The isopropanol carried out disinfection and the inflammable gas of other surgical operation preparations based on ethanol and steam.These materials can Can be impregnated with and retain in operating environment it is often found that the operation door curtain made of cloth, gown, gauze and other article.This Outward, with to limit or control many in gas that is that the anesthesia of pain of patient associates or that make unconscious patient be inflammable 's.Unchangeably, these gases put on the facial zone of patient, if fire or blast occur, the most often make head, Face, throat, respiratory tract and cervical region suffer grievous injury.These gases be also possible to dispersion and remain in body part or Under the whole body surgical operation door curtain made of cloth, this makes patient face, away from the region of head, the serious burning produced by fire or blast The risk of wound.Once the burning of these gases or steam occurs, and particularly in oxygen-enriched surgical environment, exists big Additional fuel source (such as, surgical operation gauze, the disposable door curtain made of cloth, gown, the hair of patient oneself or the skin of amount Skin and other operating rooms/interprocedual material that can burn or catch fire).
" oxidizer " (such as oxygen or nitrogen oxide (resolving into nitrogen and oxygen)) produces the three elements of fire triangle, And combustion adjuvant may be served as.Oxidizer is generally during relating to the surgical procedures of any type of calmness or anesthesia Task patient.Although in environment, larger amount of oxygen increases fire or the probability of blast, at typical atmospheric environment (such as, Air regulation/heating/climate controlling medical facilities) in the average normal oxygen level that finds be enough to support fire or blast. Apparatus and method known to some have attempted restraining oxygen in the respiratory tract of patient, to reduce the risk of burning.Unfortunate , oxygen usually escapes, and use ESU and other energy emitting device on-the-spot place or near discovery, Thus, in the presence of inflammable gas or steam, serve as the combustion adjuvant of fire or blast.And, these devices will be from The response index of any other key element (such as, fuels sources) of fire triangle is used for preventing burning.As can be seen here, these Apparatus and method for fire or the blast occurred in the normal oxygen level that may find in surgical environment are Invalid.
And, attempt preventing major part (the most all of) known medical devices of burning do not have abundant and efficiently examine Survey the ability of gas.As mentioned, these gases may task patient, or may find in patient oneself.Example As, in gastrointestinal (GI) road, antibacterial produces with the approximation ratio of about 30% methane, 44% hydrogen and 5% oxygen Gas.Methane and hydrogen are inflammable.Endoscope, colonoscope and other GI process apparatus use during various processes ESU, optical fiber source and other energy emitting device, this may light methane and hydrogen.Because the level of oxygen is too Low and signalisation can not be detected and will promote the response of amount of oxygen of blast, so only sensing oxygen or sensing oxygen level These apparatus and method for prevent blast or fire will be useless.
These known sensing medical treatment devices (such as No. 7,291,145 patent of the U.S.) also suffer from disadvantages mentioned above.These Device is typically limited to detect oxygen level and detect specific pre-during the process of burning or before immediately burning process Determine to close during oxygen level the hand-held cautery of the energy source of hand-held cautery.These device purposes are only that quantitatively survey Amount oxygen.These devices concentrate merely on the oxidizer level determined in surgical environment.As discussed, blast can Can occur in the environment with normal oxygen concentration.As can be seen here, these devices still cannot prevent many surgery handss Art fire and burning.Further, these devices only seek oxygen level；The possible inflammable any gas of they nonrecognition Body (such as those gases found in the segment surgery on-the-spot disinfection preparation commonly used and the most usual The gas found).
Accordingly, there exist the needs solving the problem together with prior art as discussed above.
