Ibhethri yepompo yokumnika

Isingeniso

Ibhethri yepompo yokufaka ihlukile kwezinye izinhlobo zamabhethri ngenxa yokuthi inikeza amandla isikhathi eside (izinsuku ezimbalwa). Ibhethri lephampu yokufaka selidume kakhulu ngoba bayanda abasebenzisi bephampu abasondela ekwelashweni kokulethwa kwe-insulin okuqhubekayo okuqhubekayo. Ukusetshenziswa kwephampu yokufaka kukhuphuka ngamadivaysi e-Continuous Glucose Monitoring (CGM), aqapha ngokunembe kakhudlwana amazinga e-glucose.

Izici zebhethri:

Izici eziningi zenza ibhethri lepompo lokumnika lihluke kwezinye izinhlobo zamabhethri asetshenziswa kumishini yezokwelapha. Lokhu kufaka phakathi ikhono layo lesikhathi eside lokuletha umthamo onembile, ukushajwa kalula kwawo, namandla okusebenzisa amabhethri alahlwayo. Isici sayo esiyinhloko umthamo wayo wesikhathi eside; lokhu kusho ukuthi ingaletha imithamo enembile izinsuku ezimbalwa ngaphambi kokudinga ukushajwa kabusha.

Ibhethri elishajekayo linika amandla iphampu ye-insulin ngokuqhubekayo noma ngezikhathi ezithile, kusetshenziswa ama-microprocessors nesofthiwe ukulawula inani le-insulin elethwayo. Amasethi okumnika aqukethe i-cannula efakwe ngaphansi kwesikhumba lapho kufakwa khona i-insulin. Ukuze kuhlinzekwe amandla ale nqubo, ugesi omncane ukhipha amanani amaminithi e-insulin ukusuka ngaphakathi kwephampu ulingene ohlelweni lwesiguli (ngaphansi kwesikhumba).

Indlela kanye nenani eliletha ngayo ukushaja kwalo ligadwa yi-microprocessor, futhi uma kudingekile, umbane kagesi udlulela kuseli yangaphakathi ye-lithium-ion. Leli seli libe seliqhuba ukushajwa ngesikhathi sokusebenza; yingakho kufanele kube nezingcezu ezimbili ukuze isebenze - iseli ye-lithium-ion yangaphakathi kanye nengxenye yangaphandle enokuxhumana kwayo okukhethekile ukuze ivumele ukushajwa kabusha.

Idizayini yebhethri yephampu yokufaka inezingxenye ezimbili:

1) iseli yangaphakathi ye-lithium-ion ekwazi ukushajwa, eyenziwe ngamapuleti e-electrode (enhle nebi), ama-electrolyte, ama-separators, ama-casing, ama-insulators (icala langaphandle), i-circuitry (izingxenye ze-electronic). Ingashajwa ngokuqhubekayo noma ngezikhathi ezithile;

2) Ingxenye yangaphandle exhuma kuseli yangaphakathi ibizwa ngokuthi i-adaptha/impahla yeshaja. Lokhu kubamba wonke amasekhethi e-elekthronikhi adingekayo ukuze ashaje iyunithi yangaphakathi ngokunikeza okukhiphayo okuthile kwamandla kagesi.

Ukusebenza okuhlala isikhathi eside:

Amaphampu okufakwayo aklanyelwe ukuletha amanani amancane e-insulin isikhathi eside. Zenzelwe ukuthi zisetshenziswe abantu abanesifo sikashukela abadinga i-insulin izikhathi eziningana ngosuku ukuze balawule ukugcwala kweglucose egazini. Amaphampu amaningi asebenza ngamabhethri ahlala izinsuku ezintathu noma ngaphezulu ngaphambi kokudinga ukushajwa. Abanye abasebenzisi bephampu yokufaka bazwakalise ukukhathazeka ngokushintsha ibhethri kaningi, ikakhulukazi uma benesinye isimo sezempilo esidinga ukuthi benze izinguquko zokugqoka njalo.

Okubi okungaba khona:

-Ukusetshenziswa kwamabhethri alahlwayo kumaphampu kuhlotshaniswa nemiphumela engase ibe mibi kwezemvelo, okuhlanganisa izindleko nokumoshakala kwamabhethri alahliwe kanye nezinsimbi ezinobuthi njenge-cadmium ne-mercury equkethwe ngaphakathi kweseli ngalinye (ngamanani amancane kakhulu).

-Iphampu yokufaka ayikwazi ukushaja womabili ibhethri ngesikhathi esisodwa;

-Amaphampu namabhethri e-insulin kuyabiza futhi adinga ukushintshwa njalo ezinsukwini ezi-3.

-Ibhethri elingasebenzi kahle lingabangela ukubambezeleka kokulethwa kwemithi;

-Lapho ibhethri seliphelile, iphampu yokufaka iyavaleka futhi ayikwazi ukuletha i-insulin. Lokhu kusho ukuthi ngeke isebenze, noma ikhokhisiwe.

Isiphetho:

Nakuba [ibhethri yephampu yokufaka] inobuhle nokubi okuningana, kusobala ukuthi iziguli zidinga ukukala izinzuzo ngokumelene nezingozi. Umuntu kufanele ngaso sonke isikhathi athintane nodokotela ngaphambi kokuqala ukwelashwa ngephampu yokufaka i-insulin.
