I. Kev npaj
1. Tshawb xyuas kev sib raug zoo: Tshawb xyuas lub stethoscope hom thiab qauv, thiab yuav ib lub diaphragm tshiab ntawm qhov luaj li cas; xaiv hom khoom tseem ceeb- cov khoom siv tshwj xeeb kom tsis txhob muaj cua nkag.
2. Tshawb xyuas lub diaphragm tshiab: xyuas kom lub diaphragm tshiab yog tiaj tus, tsis muaj kab nrib pleb, thiab khaws cov elasticity zoo; tsis txhob siv cov khoom uas twb muaj lawm los yog tawv.
3. Npaj cov cuab yeej: Muaj cov phuam da dej thiab ntxuav cov paj rwb swabs npaj; rau qee cov qauv, me me ntawm talcum hmoov tuaj yeem pab nrog kev teeb tsa.
II. Tshem Tawm Qhov Qub Diaphragm
1. Txheeb xyuas cov txheej txheem fastening: Saib seb qhov qub diaphragm ruaj ntseg li cas- hom hom xws li snap- haum lossis ntsia hlau- ntawm (rotating) tsim; qee lub npe (xws li 3M) nrog tunable diaphragms xav tau cov tswv yim tshem tawm tshwj xeeb.
2. Tshem tawm cov qub diaphragm: Rau snap- haum hom, maj mam rub lub ntug nrog koj lub ntsis ntiv tes kom tev nws maj mam; rau cov ntsia hlau- ntawm hom, tuav lub nplhaib tuav thiab tig nws txee-clockwise kom tshem nws. Yog hais tias lub diaphragm yog daig, so cov npoo nrog ib tug cawv swab los pab loosen nws.
3. Tsis txhob muaj qhov pitfalls ntau: Tsis txhob siv cov cuab yeej ntse zoo li cov ntsia hlau los txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws yuav tsum tsis txhob siv cov cuab yeej ntse zoo li cov ntsia hlau ntsia hlau.
III. Txhim kho lub Diaphragm tshiab
1. Ntxuav qhov chaw sib cuag: Siv cov paj rwb swab dipped nyob rau hauv ib qho me me ntawm cov cawv tshuaj kho mob los so qhov zawj uas lub hauv siab ua tau raws li lub diaphragm, tshem tawm cov nplaum los yog cov av.
2. Teem thiab nruab: Teem lub diaphragm tshiab nrog rau ntawm ntug ntawm lub hauv siab, ua kom lub hauv nruab nrab aligns zoo kawg nkaus nrog lub suab channel qhib; rau qee cov qauv, maj mam plua plav cov npoo sab hauv ntawm lub diaphragm nrog talcum hmoov tuaj yeem txo kev sib txhuam thaum lub sijhawm teeb tsa.
3. Ruaj ntseg thiab nruj: Nias ib ncig ntawm ntug ntawm lub diaphragm kom txog thaum nws zaum hauv qhov zawj tag nrho lossis koj hnov snap; rau cov ntsia hlau- ntawm hom, nruj nreem tuav lub nplhaib clockwise. Xyuas kom lub diaphragm nyob tiaj tus tsis muaj wrinkles thiab cov npoo tsis lifting.
IV. Tom qab-installation Check
1. Kev sim ua haujlwm: Muab tso rau ntawm lub stethoscope thiab maj mam coj mus rhaub lub diaphragm nto nrog koj tus ntiv tes; lub suab meej tapping yam tsis muaj huab cua -tawm suab nrov qhia tau hais tias kev txhim kho tiav.
2. Fine-tuning: Yog hais tias lub suab auscultation yog faint, rov- xyuas seb lub diaphragm yog tag nrho kaw; xyuas kom tsis muaj kev hloov pauv, tom qab ntawd nias cov npoo kom ruaj khov dua.
