Interventional radiology is an under the guidance of medical imaging equipment, the use needle catheter, guide wire, and other equipment to reach new subject for diagnosis or treatment of the lesion site because of its minimally invasive, accurate positioning, high curative effect, quick effect, and low complication rates are rapid development, has been widely used in clinical, also attracted the young physician engaged in the field of practice. Young doctors are often very interested in intervention in radiology, especially in the process of intervention, but often neglect their own professional protection. In addition, the previous experience of education is less, the awareness is weak, and the beginners often care for this is also important factor. The following two aspects of radiation protection and the prevention of injury infection are related to the occupational protection of interventional radiological operation learning. 1 the radiation protection Currently involved in operating the majority is, under the X-ray guided interventional operation than the rest of the X-ray diagnosis of radiation dose perspective has greatly increased, so how to reduce the radiation of interventional radiology workers career, students should strictly according to the principles of radiation protection requirements. 1 time principle radiometric measurement and exposure time are positively proportional, so exposure time should be minimized. The students should familiarize themselves with the features and operation methods of various operating equipment before they are formally operated, and repeat the practice on the mold. The steps, equipment, anatomical structure and precautions to be used to describe the operation are made in front of the platform so as to achieve the smooth completion and reduce the operation time. In operation, except for the observation of the observation, should stop the exposure in time, the beginners will always step on the perspective key after the operation has stopped, should timely remind. Students who do not need to be in an operation should be reminded to leave. 2 distance principle because of X line to walk in space during wire scattered, radiation intensity varies inversely as the square of the distance, that if the distance from the source to double the dose to reduce to a quarter of the original. Although this relationship is suitable for a point source, scattering source, but when the patient is an important clinical distance principle is very important to reduce the radiation dose, should be as far from the tube (patient exposure site). Also, students in the first operation, control of the catheter ability is poorer, commonly used both hands hold a part of the control at the same time, certainly will cause the body to the ball in the tilt, cause increased radiation dose, especially against the lens and the thyroid gland, should let the students develop a tall right from the start, his hands open posture and habits. 3 shielding principle X line is attenuated by the material’s thickness, except the attenuation coefficient of the material itself. Therefore, a small amount of attenuation (shielding) material can greatly reduce the intensity of X rays, such as 0.5mm lead (conventional lead apron) can reduce the strength of X line by more than 90%. Staff in the intervention room should wear a lead apron and remind students to wear lead glasses, lead scarves and lead caps to protect sensitive areas such as the lens and thyroid. In addition, use of lead glass or baffles as much as possible to further reduce the radiation dose. The size of the aperture principle determines the area of the X-ray beam, the aperture reduction is reduced by the X ray, and the amount of the human body is reduced. Needed for diagnosis and treatment of field of vision is not affected, therefore, under the premise of should remind students as much as possible to stop down 2 damage infection prevention intervention as surgical operation, always with the patient’s blood contact, and the current domestic most intervention operation associated with the treatment of tumor patients, especially in liver cancer patients, often hepatitis history, should remind students pay attention to protection, especially avoid skin needles and equipment damage. 1 to avoid the damage of various surgical instruments shall have a fixed position, especially the needles and other sharp objects, in order to avoid accidentally prick the skin in the process of operation, no longer use needles, etc should be promptly put into special containers. The syringe should pay attention to have the close connection with the catheter, so as not to splash into the eyes. Vaccination against hepatitis b vaccination is the most effective measure to prevent hepatitis b virus (HBV) infection. The effective rate is 96% ~ 99%, and it also has a preventive effect on the liver. Therefore, all students who have negative antigen of hepatitis b should be inoculated with hepatitis b vaccine, complete a whole process to be inoculated half a year, to check whether the body produced antibodies. If HBV is present in the body, even if it is exposed to HBV blood, there is no risk of HBV infection. Send your message to us: Post time: Dec-27-2017

Is raideolaíocht idirghabhálach ar faoi threoir an trealamh leighis íomháithe, an úsáid catheter snáthaid, treoir sreang, agus trealamh eile a bhaint amach ábhar nua chun diagnóis nó cóireáil an suíomh lesion mar gheall ar a minimally ionrach, aimsiú suímh cruinn, éifeacht leigheasacha ard, éifeacht mear , tá agus rátaí complication íseal forbairt go mear, tá úsáid go forleathan i cliniciúil, mheall chomh maith leis an dochtúir óg a ghlacadh sa réimse cleachtais. Tá dochtúirí óga go minic an-suim acu i idirghabháil i raideolaíocht, go háirithe sa phróiseas idirghabhála, ach is minic a faillí a chosaint ghairmiúil féin. Lena chois sin, is é an taithí roimhe seo ar oideachas níos lú, is é an feasacht lag, agus na thosaitheoirí go minic cúram tá sé seo freisin fachtóir tábhachtach. An dá gnéithe seo a leanas de chosaint radaíochta agus le cosc ar ionfhabhtú díobháil a bhaineann le cosaint ceirde na foghlama oibriú idirghabhála raideolaíoch. 1 Is é an chosaint radaíochta Faoi láthair ní baint acu feidhmiú an chuid is mó, faoi X-gha treoraithe oibriú idirghabhála ná an chuid eile den diagnóis X-gha pheirspictíocht dáileog radaíochta tar éis méadú go mór, mar sin conas a laghdú ar an radaíocht na n idirghabhála oibrithe raideolaíochta gairme, mic léinn Ba chóir go docht de réir na prionsabail a bhaineann le ceanglais maidir le cosaint radaíochta. 1. 1 tomhas ama prionsabal radaiméadracha agus am nochtadh dearfach comhréireach, mar sin ba chóir am nochtadh a íoslaghdú. Ba cheart na daltaí eolas a chur na gnéithe agus na modhanna oibriú trealaimh oibriúcháin éagsúla sula ndéantar iad a oibriú go foirmiúil, agus déan an cleachtadh ar an múnla. Tá na céimeanna, trealamh, struchtúr anatamaíocha agus réamhchúraimí atá le húsáid chun cur síos a dhéanamh ar an oibríocht a dhéantar i os comhair an ardán ionas go mbainfear amach an gcrích iad go réidh agus laghdú ar an am a oibriú. I bhfeidhm, ach amháin i gcás an breathnú ar an mbreathnú ar cóir, stop an nochtadh in am, beidh na tosaitheoirí chéim i gcónaí ar an eochair pheirspictíocht tar éis an oibríocht a stopadh, ba chóir i gcuimhne tráthúil. Ba chóir do dhaltaí nach bhfuil gá a bheith in oibríocht a chur i gcuimhne a fhágáil. 1. 2 achar prionsabal gheall ar X líne chun siúl i spás le linn sreang scaipthe, athraíonn déine radaíocht contrártha mar an cearnach de an t-achar, más rud é an t-achar ón bhfoinse a dhúbailt an dáileog a laghdú go dtí an ceathrú cuid de na bunaidh. Cé go bhfuil an caidreamh oiriúnach do foinse pointe, foinse scaipeadh, ach nuair a bhíonn an t-othar prionsabal tábhachtach achar chliniciúil Tá an-tábhachtach chun laghdú ar an dáileog radaíochta, ba chóir go mbeadh chomh fada ón fheadáin (láithreán othair faoi lé). Ina theannta sin, mic léinn sa chéad ngníomh, is é rialú an cumas gcaitidéar boichte, a úsáidtear go coitianta dá lámh a shealbhú mar chuid den rialú ag an am céanna, a chur faoi deara cinnte an comhlacht chun an liathróid sa tilt, mhéadaigh faoi deara dáileog radaíochta, go háirithe i gcoinne an lionsa agus an fhaireog thyroid, ba cheart go lig do na scoláirí a fhorbairt ceart ard ó thús, a lámha staidiúir oscailte agus nósanna. 1. 3 sciath prionsabal X líne laghdú ach tiús an t-ábhar, ach amháin an chomhéifeacht tanúcháin an t-ábhar féin. Dá bhrí sin, is féidir méid beag de tanúcháin (shielding) ábhar a laghdú go mór an déine X ghathanna, mar shampla 0.5mm luaidhe (naprún luaidhe traidisiúnta) a laghdú an neart X líne ag níos mó ná 90%. Ba chóir don fhoireann sa seomra idirghabhála chaitheamh naprún luaidhe agus cuir i gcuimhne do mhic léinn a chaitheamh gloiní luaidhe, scaifeanna luaidhe agus caipíní mar thoradh ar limistéir íogaire ar nós an lionsa agus thyroid a chosaint. Lena chois sin, úsáid a bhaint as gloine luaidhe nó baffles oiread agus is féidir a laghdú a thuilleadh ar an dáileog radaíochta. Cinneann an méid de na bprionsabal Cró réimse an bhíoma X-gha, tá an laghdú Cró laghdú den X gha, agus tá an méid an gcorp an duine a laghdú. Nach bhfuil ag teastáil chun diagnóis agus cóireáil radhairc difear, dá bhrí sin, faoi phrionsabal na chóir mheabhrú do dhaltaí oiread agus is féidir chun stop a chur síos 2 damáiste idirghabhála cosc ionfhabhtú mar obráid mháinliachta, i gcónaí le teagmháil fola an othair, agus an láthair an chuid is mó intíre oibríocht idirghabhála a bhaineann leis an chóireáil na n-othar meall, go háirithe i othair a bhfuil ailse ae, stair heipitíteas minic, ba cheart go gcuimhne íocann mic léinn aird a thabhairt ar chosaint, go háirithe a sheachaint snáthaidí craicinn agus damáiste trealamh. 2. 1 a sheachaint an damáiste na n-ionstraimí máinliachta éagsúla beidh seasamh seasta acu, go háirithe na snáthaidí agus rudaí géara eile, d'fhonn a sheachaint trí thimpiste faobhar an craiceann sa phróiseas oibriú, a thuilleadh snáthaidí úsáid, ba cheart srl a chur go pras i coimeádáin speisialta. Ba chóir an steallaire aird a bheith acu ar an nasc dlúth leis an gcaitidéar, ionas nach a splancscáileán ar na súile. Vacsaíniú in aghaidh vacsaíniú heipitíteas b an beart is éifeachtaí chun cosc heipitíteas b víreas (HBV) ionfhabhtú. Is é an ráta éifeachtach 96% ~ 99%, agus tá sé chomh maith éifeacht choisctheach ar an ae. Dá bhrí sin, na daltaí go léir a bhfuil Ba chóir go antaigin diúltach heipitíteas b a ionaclaithe le vacsaín heipitíteas b, chomhlánú próiseas iomlán a bheith ionaclaithe leath na bliana, a sheiceáil cibé an gcomhlacht a tháirgtear antashubstaintí. Má tá HBV i láthair sa chorp, fiú amháin más rud é go bhfuil sé faoi lé fuil HBV, níl aon riosca ionfhabhtaithe HBV. Seol do theachtaireacht a chur chugainn: Post ama: Dec-27-2017
