How Does Electric Solenoid Air Valves and Diaphgram Pumps Work in Blood Pressure Monitors?

I-DC DiaphragmPumps ku-Blood Pressure Monitors

Uhlobo Nokwakha: Amaphampu asetshenziswayo ajwayelekileamaphampu we-diaphragm amancane. Aqukethe i-diaphragm eguquguqukayo, ngokuvamile eyenziwe ngerabha noma into efanayo ye-elastomeric, ehamba phambili naphambili ukuze isuse umoya. I-diaphragm ixhunywe ku-motor noma i-actuator ehlinzeka ngamandla okushayela. Isibonelo, kwamanye amamodeli, injini encane ye-DC inika amandla ukunyakaza kwe-diaphragm. Lo mklamo uvumela ukulawula okunembile kwevolumu yomoya kanye nokukhishwa kwengcindezi.

Isizukulwane Sokucindezela kanye Nokulawula: Ikhono lephampu lokukhiqiza nokulawula ingcindezi libalulekile. Kumelwe ikwazi ukufutha i-cuff kungcindezi ngokuvamile esukela ku-0 iye ngaphezu kuka-200 mmHg, kuye ngezidingo zokulinganisa. Amaphampu athuthukisiwe anezinzwa zokucindezela ezakhelwe ngaphakathi eziphendula iyunithi yokulawula, okuzivumela ukuthi zilungise izinga lokukhuphuka kwamandla emali futhi zigcine ukukhuphuka kwengcindezi engaguquki. Lokhu kubalulekile ukuze kuvalwe ngokunembile i-artery futhi uthole ukufundwa okuthembekile.

Ukusetshenziswa kwamandla kanye Nempumelelo: Uma kubhekwa ukuthi iziqaphi zomfutho wegazi eziningi zisebenza ngebhethri, ukusetshenziswa kwamandla okumpompa kuwukucatshangelwa okubalulekile. Abakhiqizi balwela ukuklama amaphampu angaletha ukusebenza okudingekayo kuyilapho enciphisa ukudonsa kwebhethri. Amaphampu asebenzayo asebenzisa imiklamo yemoto ethuthukisiwe futhi alawule ama-algorithms ukunciphisa ukusetshenziswa kwamandla. Isibonelo, amanye amaphampu adonsa amandla abalulekile kuphela phakathi nesigaba sokuqala sokwehla kwamandla emali abese esebenza ngezinga eliphansi lamandla phakathi nenqubo yokulinganisa.

Ama-valve ku-Blood Pressure Monitors

Imininingwane Yevalufu Yokungena: Ivalvu yokungena ivamise ukuba yi-valve yokuhlola indlela eyodwa. Yakhelwe nge-flap encane noma indlela yebhola evumela ukuthi umoya ugeleze ohlangothini olulodwa kuphela - ungene ku-cuff. Lo mklamo olula kodwa ophumelelayo uvimbela umoya ukuthi ungaphumi ubuye ngepompo, uqinisekisa ukuthi i-cuff ivuthela kahle. Ukuvuleka nokuvalwa kwevalvu kufakwe isikhathi esiqondile ngokusebenza kwephampu. Isibonelo, lapho iphampu iqala, i-valve yokungena iyavuleka ngokushesha ukuze ivumele ukungena komoya okubushelelezi.

I-Outflow Valve Mechanics: Ama-valve aphumayo angahluka ekwakhiweni kwawo kodwa ngokuvamile amavalvu e-solenoid alawulwa ngokunemba. Lawa ma-valve alawulwa nge-elekthronikhi futhi angavuleka futhi avale ngokunemba okukhulu. Zilinganisiwe ukuze zikhulule umoya ku-cuff ngezinga elithile, ngokuvamile phakathi kuka-2 no-3 mmHg ngomzuzwana phakathi nesigaba sokunciphisa amandla. Lesi silinganiso sibalulekile njengoba sivumela izinzwa ukuthi zithole ngokunembile ukucindezela okuguqukayo njengoba umthambo uvuleka kancane kancane, okubalulekile ekunqumeni kokubili umfutho wegazi we-systolic ne-diastolic.

Isondlo Nokuqina: Kokubili ama-valve angenayo naphumayo adinga ukuhlala isikhathi eside futhi enokwethenjelwa, njengoba noma yikuphi ukungasebenzi kahle kungaholela ekufundweni okungalungile. Ukugcinwa okuvamile, njengokuhlanza nokuhlola, kuvame ukutuswa abakhiqizi. Amavaluvu enziwe ngezinto zekhwalithi ephezulu, njengensimbi engagqwali noma amapulasitiki amelana nokugqwala, avame ukuba nesikhathi eside sokuphila nokusebenza okungcono ngokuhamba kwesikhathi. Kwezinye izimo, izindlela zokuzihlanza zifakwa ekwakhiweni kwe-valve ukuvimbela ukuvaleka ngothuli noma ezinye izinhlayiya.

Kafushane, amaphampu nama-valve kumamonitha womfutho wegazi yizingxenye eziklanywe kakhulu ezidinga ukunemba nokuthembeka. Ukuklanywa kwazo okuningiliziwe nokusebenza okufanele yikho okwenza isilinganiso sanamuhla somfutho wegazi sinembile futhi sithembeke, sivikele impilo yabantu abaningi.
