Wok na samting insait long masin bilong 'pneumoperitoneum'
bihain bilong samting
Ol i separetim wol bilong bel long ol 'abdominal visceral organs' long rot bilong putim Co ν win i go insait long bodi bilong man we i gat gutpela lukluk na i stap gut long kamapim na lukautim 'pneumoperitoneum', bai i gat inap spes bilong lukluk na spes bilong operesen bilong mekim 'abdominal endoscopic surgery'. Olsem na, bikpela wok bilong masin bilong 'pneumoperitoneum' em long kamapim gutpela na bosim win.
seip
Planti taim, em i gat pawa modul, kontrol modul, ges paiplain na ol kain kain wok valv (olsem presa ridusen valv, flo kontrol valv, sefti valv, na ol narapela).
Ol kain kain sensa (olsem sensa bilong tempereja, sensa bilong presa na sensa bilong ges flow rate) i stap insait long kontrol modul bilong glasim presa bilong win, flow rate na ol narapela stet bilong CO Ω ges.
Analisis na mentenens bilong ol asua

Samting i wok long kamap:
Pawa saplai bilong ol ikwipmen em i nomol, tasol ol i no inap kirapim ikwipmen long nomol taim yu presim 'start key'.
Skelim na lukautim ol asua:
Bihain long ol i givim pawa long ol ikwipmen, pawa indiketa i save kamap gut, tasol ventilesen long ki i no wok. Bikos planti manmeri i save yusim ol ki bilong ol ikwipmen, ol i ting pastaim olsem ol ki i bagarap. Kisim gut 'display key board', skelim ol 'ventilation keys' bilong ol ikwipmen wantaim wanpela 'multimeter', na ol i painim olsem ol ki i stap gut;
Bihain skelim ol waia bilong displei panel na kontrol bod, na ol i painimaut olsem ol waya bilong ikwipmen tu i orait;
Senisim displei bod na kontrol bod bilong masin bilong 'pneumoperitoneum' we i wok gut wantaim masin bilong 'pneumoperitoneum' we i no wok gut. Dispela tes i painim olsem ol ikwipmen i wok gut, olsem na wok painimaut bilong ol asua i lukluk long displei bod na kontrol bod;
Ol i bin painim sot seket long displei bod na kontrol bod bilong masin bilong 'pneumoperitoneum' we i no wok gut, na ol i painim olsem i no gat wanpela bikpela sot seket i stap long seket bod;
Bihain, yusim rot bilong senisim, ol i senisim 'fault board' long ol nomol ikwipmen. Long pinis, ol i painim olsem wok bilong displei bod i orait na kontrol bod i no wok gut;
Skelim pawa saplai bilong ol komponen bilong sip. Voltej bilong tes pin em + 5V, na pawa saplai em i nomol;
Bikpela kontrol bod em i nambawan samting bilong programim lojik divais bilong ikwipmen, na i no gat klia sain bilong sot seket bagarap bihain long skelim;
Taim ol i yusim rot bilong senisim, ol i painimaut olsem bikpela 'chip' na 'memory chip' i wok gut;
Ol i testim ol 'logic devices' klostu long 'main chip' na 'memory chip', na ol i painim olsem 'latch port' i wok nogut tru;
Long dispela taim, senisim ol nupela komponen bilong wankain model, stretim bek koneksen bilong bod na pawa long tes, ol ikwipmen i go bek long nomol na asua i pinis.

Samting i wok long kamap:
Alarm bilong ol ikwipmen.
Skelim na lukautim ol asua:
Taim ol i askim long 'error code' bilong ikwipmen, ol i painimaut olsem 'error code' em i 'equipment flow sensor' o 'circuit fault' we i wankain. Rausim 'control board', na pastaim stretim ol hevi bilong 'flow sensor circuit'.
Mesarim ol amplifikesen komponen bilong 'flow sensor' we i no gat sot seket, na bihain skelim 'bypass resistance' na 'capacitance' bilong ol amplifikesen komponen bilong 'flow sensor', na ol i painimaut olsem i no gat wanpela samting i no stret.
Long skelim gut moa asua, senisim ol 'amplification' komponen bilong 'flow sensor', na asua bilong ikwipmen i stap yet.
Long dispela taim, ol i ting olsem 'flow sensor' i no wok gut. Bihain long senisim 'flow sensor', ol ikwipmen i go bek long nomol na asua i pinis.
Asua namba tri
Samting i wok long kamap:
I gat wanpela nois i pairap taim ol i putim win long ol ikwipmen.
Skelim na lukautim ol asua:
Pastaim, painimaut ples bilong krai, opim antap kava bilong ikwipmen long soim 'internal air circuit', painim ples bilong 'sound source', na painim olsem krai i stap long 'collector block' namel long ikwipmen. Long wankain taim, ol i painim olsem i gat ol yelopela mak bilong oil long paiplain insait long ikwipmen. Pastaim ol i skelim olsem 'air leakage' na 'sealing' bilong ol 'high' na low pressure valve' bilong 'ea circuit' bilong ikwipmen i no tait.
Bikos wok bilong hai na lo presa valv em long pasim input na stopim hai-presa ges long bagarapim ol intanel paiplain divais, pastaim long rausim, yu mas rekodim posisen bilong knob long hai na lo presa valv, na bihain rausim 6-pela skru bilong pasim hai na lo presa valv long daunbilo. Sapos yu painim planti mak bilong oil insait long valv, klinim gut valv na 'sealing ring', na putim bek antap bilong valv long ples bilong en pastaim, stretim ol skru na go bek long ples bilong 'valve top knob'.
Rausim paiplain bilong ol ikwipmen na klinim. Putim kolekta blok na ges paiplain i go bek insait long ikwipmen. Ol i painimaut olsem 'high' na low pressure valve' i gat liklik 'air leakage' long 'ventilation test'. Stretim gut 'valve top knob' inap long taim i no gat win i lik, na nois i no stret insait long ikwipmen i pinis.
Bihain long pawa on tes, wok bilong ikwipmen i go bek long nomol na asua i pinis.
Long sotpela tok, sapos ol ikwipmen i bagarap, ol medikel wokman i mas inap long mekim stretpela na hariap wok painimaut long ol asua na mekim gutpela mentenens. Long dispela rot tasol ol i ken mekim 'startup rate' bilong ol ikwipmen i kamap gutpela na ol i ken yusim ol long klinik.
