Kev sib xyaw thiab kev siv ntawmtshuab tshuaj loog
Tshuaj loog yog hais txog qhov tsis nco qab ib ntus ntawm tag nrho lossis ib feem ntawm lub cev rau lub hom phiaj ntawm kev kho mob phais. Muaj ntau txoj kev siv tshuaj loog, xws li acupuncture anesthesia, txhaj tshuaj loog thiab inhalation anesthesia. Tam sim no, txoj kev siv tshuaj loog dav dav siv hauv tsev kho mob tseem yog kev nqus tshuaj loog.
Lub tshuab tshuaj loog yog ib qho cuab yeej siv tshuaj loog rau kev siv tshuaj loog. Cov tshuab tshuaj loog niaj hnub tab tom txhim kho mus rau qhov kev txawj ntse thiab kev sib koom ua ke. Cov khoom sib koom ua ke, hloov tau, txhim khu kev qha, compact, thiab siv tau zoo. Lub interface yog meej thiab tus phooj ywg, thiab kev ua haujlwm yog yooj yim thiab ceev. Lub tshuab hluav taws xob tswj hluav taws xob xa hluav taws xob Ua tau-nyob rau hauv hluav taws xob tswj kev siv tshuaj loog lub tshuab ua pa, sib xyaw ua pa hluav taws xob, thiab kev ntsuas roj sib xyaw ua ke. Siab thiab qis micro- ntws tshuaj loog yog qhov zoo tshaj plaws ua ke ntawm cov tshuab tshuaj loog niaj hnub.
Lub cim tshiab ntawm cov chaw ua haujlwm tshuaj loog yuav nthuav dav mus rau tag nrho cov kev kho mob, thiab tuaj yeem sib txuas nrog cov khoom siv hauv tsev kho mob, sib txuas lus, txhais, kho cov txheej txheem tshuaj loog thiab sau tseg thiab ntsuas cov txiaj ntsig ntawm kev siv tshuaj loog txhawm rau txhim kho kev saib xyuas neeg mob zoo. Tsim kom muaj chaw ua haujlwm zoo rau cov kws kho mob.
Lub tshuab tshuaj loog niaj hnub tuaj yeem muab faib ua: cov khoom siv roj thiab cov khoom xa tawm, cov tshuaj loog roj vaporizer, ua pa Circuit Court, tshuaj loog lub tshuab ua pa, kev saib xyuas kev nyab xeeb thiab cov roj seem tshem tawm.
1. Cov khoom siv roj thiab khoom xa tuaj
Cov khoom siv roj muaj xws li compressed gas cylinder lossis central gas qhov chaw, ib qho - txoj kev valve, overflow valve, lim, siab ntsuas, roj siab regulator, flow meter thiab N2O / O2 proportional interlock control device, nitrous oxide kaw{{ 3}}off valve, thiab lwm yam. Cov tshuab tshuaj loog yuav tsum tau nruab nrog cov ntsuas ntsuas rau ntau qhov chaw roj. Flowmeter units muaj nyob rau hauv L / min thiab mL / min (lossis tsawg dua 2L / min flowtubes) flowtubes rau cov tshuaj loog qis. Nyob rau tib lub sijhawm, nws yuav tsum tau nruab nrog N2O / O2 proportional interlock control device los xyuas kom meej tias cov pa oxygen concentration ntawm cov zis tshuaj loog tsis tsawg dua 25 feem pua; Thaum cov pa oxygen tsis txaus lossis cuam tshuam, cov khoom siv nitrous oxide raug txiav tawm. N2O/O2 feem ntau sib cuam tshuam kev tswj cov cuab yeej thiab nitrous oxide kaw{10}}off valve yog cov cuab yeej siv tshuab, yog li ceev faj kom tsis txhob ua tsis tiav. Hauv kev siv txhua hnub, peb yuav tsum tau them sai sai rau qhov piv ntawm O2 / N2O, xyuas seb lub ntsuas dej ntws los, thiab tso siab rau lub tshuab tshuaj loog lossis lwm yam kev saib xyuas los saib xyuas O2 / N2O concentration hauv lub tshuab ua pa, uas tuaj yeem raug. ntsuas qhov kev ua haujlwm tam sim no ntawm lub tshuab tshuaj loog. Ntau lub tshuab siv tshuaj loog niaj hnub muaj 55L / min oxygen bypass, uas tuaj yeem nkag mus rau hauv lub tshuab ua pa sai thiab ncaj qha los ntawm kev sib cuam tshuam thaum muaj xwm txheej ceev, uas ua rau muaj txiaj ntsig zoo rau kev ua haujlwm oxygen ntawm cov kws kho mob anesthesiologist.
2. Tshuaj loog gas vaporizer
Lub vaporizer yog ib feem tseem ceeb ntawm lub tshuab tshuaj loog. Nws qhov zoo tsis tsuas yog cim cov qib tsim ntawm lub tshuab tshuaj loog, tab sis kuj cuam tshuam rau cov nyhuv thiab kev ua tiav ntawm kev nqus tshuaj loog, thiab cuam tshuam ncaj qha rau kev nyab xeeb ntawm tus neeg mob. Lub hauv paus ntsiab lus ntawm lub vaporizer yog siv cov kev hloov pauv ntawm qhov kub thiab txias ntawm ib puag ncig ib puag ncig kom tig cov tshuaj loog mus rau hauv cov pa roj evaporative, thiab los ntawm qee qhov ntawm cov cab kuj roj, ib feem ntawm cov roj nqa cov roj saturated anesthetic rau hauv. ib tug airflow nrog ib tug tej yam concentration ntawm tshuaj loog vapor ncaj qha mus rau hauv cov tshuaj loog. lub voj.
3. Ua pa Circuit Court
The breathing circuit is a combined air circuit device connecting the anesthesia machine and the patient, delivering anesthesia mixed gas to the patient and returning the patient's exhaled gas, thereby realizing the normal exchange of oxygen and carbon dioxide gas. It is mainly composed of breathing pipeline, CO2 absorption tank, breathing valve, storage bag, mask, computer-controlled manual valve, exhaust valve, pressure limiting valve, development/semi-open valve, etc. The directional circulation of gas is formed by the valve and the pipeline, and the soda lime in the CO2 absorption tank is used to absorb CO2 and water to supply fresh gas to the patient. The machine-controlled manual valve facilitates the user to choose between manual control or machine control through an anesthesia ventilator. The semi-open valve, pressure limiting valve, etc. can make the breathing circuit flexibly control the pressure limit, which is conducive to spontaneous breathing.
4. Lub tshuab ua pa tawm tshuaj loog
Lub tshuab ua pa tshuaj loog tau dhau los ua ib feem tseem ceeb ntawm lub tshuab tshuaj loog. Vim muaj kev loj hlob sai ntawm kev siv tshuab ua pa hauv kev nqus tshuaj loog hauv xyoo tas los no, nws ua haujlwm tau zoo thiab ua haujlwm me me. Cov tsav tsheb ntawm lub tshuab ua pa tawm yog pneumatic, pneumatic hluav taws xob tswj thiab hluav taws xob. Cov tshuab siv tshuaj loog tshiab tau nruab nrog lub tshuab ua pa, feem ntau yog cov pa oxygen- tsav hluav taws xob tswj. Cov tshuab ua pa tshuaj loog tshiab kawg yog tsim - hauv cov tshuab ua pa hluav taws xob thiab hluav taws xob tswj lub tshuab ua pa. Lawv tuaj yeem muab ntxiv los ntawm huab cua thaum cov roj raug txiav tawm yam tsis muaj tus neeg tsav tsheb kom muaj kev nyab xeeb ntawm cov neeg mob. . Lub tshuab ua pa ib txwm yog lub tshuab pneumatic thiab hluav taws xob tswj lub tshuab ua pa. Sab hauv thiab sab nraud ntawm lub hnab folding nyob rau hauv lub pob tshab sealing cover yog ob txheej ntawm cua Circuit Court, uas tsav cov huab cua mus compress lub folding hnab thiab tsav cov tshuaj loog nyob rau hauv lub hnab kom nkag mus rau tus neeg mob, tsim ib tug tsav tsheb gas qhov chaw. , tshuaj loog airflow ob - voj system.
4. Kev saib xyuas kev nyab xeeb
Cov tshuab tshuaj loog niaj hnub muaj kev saib xyuas kev nyab xeeb. Lub kaw lus suav nrog lub tswb rau cov pa oxygen tsis txaus, kev txiav tawm -tawm cov khoom siv rau cov pa oxygen tsis txaus / cuam tshuam ntawm nitrous oxide, qhov ntim thiab qhov ntsuas qhov ntsuas thiab lub tswb tsis raug. Qhov kev soj ntsuam feem ntau suav nrog kev nqus pa oxygen, qhov ntim ntawm lub qhov dej tas mus li, lub siab ntawm txoj hlab ntsws, lub sijhawm ua pa, qhov kawg -tidal CO2 concentration, thiab cov pa tshuaj loog. Siv microcomputer los ua cov txheej txheem thiab tso saib ntau cov ntaub ntawv, thiab txuas cov cuab yeej ceeb toom, tshwj xeeb tshaj yog kev saib xyuas kev ua pa, kev ncig, paj hlwb thiab cov leeg tuaj yeem pom tau, uas ua rau muaj txiaj ntsig zoo ntawm kev kho tshuaj loog thiab kev nyab xeeb ntawm cov neeg mob, thiab txhim kho qhov kev vam meej. ntawm kev phais.
5. Kev tshem tawm cov roj seem
Lub kaw lus tshem tawm cov roj seem khaws cov roj seem nyob hauv lub tshuab tshuaj loog thiab cov pa tso pa tawm los ntawm tus neeg mob, thiab tso nws tawm ntawm chav ua haujlwm los ntawm cov kav dej kom tsis txhob muaj pa phem hauv chav ua haujlwm. Nws feem ntau suav nrog cov khoom siv khib nyiab pov tseg thiab tso tawm, uas yog tsim los ntawm kev tswj lub valve, tso tawm valve, lub tshuab nqus tsev vacuum, cov kav dej thiab cov khoom sib txuas.
