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

Mapampu a DC Diaphragm mu Owonera Kupanikizika kwa Magazi

Mtundu ndi KapangidweMapampu omwe amagwiritsidwa ntchito nthawi zambiri amagwiritsidwa ntchitomapampu ang'onoang'ono a diaphragmZimakhala ndi diaphragm yosinthasintha, yomwe nthawi zambiri imapangidwa ndi rabara kapena chinthu chofanana ndi elastomeric, chomwe chimayenda mmbuyo ndi mtsogolo kuti chichotse mpweya. Diaphragm imalumikizidwa ku mota kapena actuator yomwe imapereka mphamvu yoyendetsera. Mwachitsanzo, m'mamodeli ena, mota yaying'ono ya DC imayendetsa kayendedwe ka diaphragm. Kapangidwe kameneka kamalola kuwongolera bwino kuchuluka kwa mpweya ndi mphamvu yotuluka.

Kupanga ndi Kulamulira Kupanikizika: Kutha kwa pampu kupanga ndikuwongolera kuthamanga kwa magazi ndikofunikira kwambiri. Iyenera kukhala yokhoza kudzaza cuff ku kuthamanga kwa magazi komwe nthawi zambiri kumakhala kuyambira 0 mpaka kupitirira 200 mmHg, kutengera zomwe zimafunika muyeso. Mapampu apamwamba ali ndi masensa okakamiza omwe amalowa mkati omwe amayankha ku unit yowongolera, zomwe zimawathandiza kusintha kuchuluka kwa mpweya ndikusunga kuthamanga kwa magazi kokhazikika. Izi ndizofunikira kuti mitsempha yamagazi ikhale yotseguka molondola ndikupeza mawerengedwe odalirika.

Kugwiritsa Ntchito Mphamvu ndi Kuchita Bwino: Popeza kuti ma monitor ambiri a kuthamanga kwa magazi amayendetsedwa ndi batri, kugwiritsa ntchito mphamvu ya pampu ndikofunikira kwambiri. Opanga amayesetsa kupanga mapampu omwe angapereke magwiridwe antchito ofunikira pomwe akuchepetsa kutulutsa kwa batri. Mapampu ogwira ntchito bwino amagwiritsa ntchito mapangidwe abwino a mota ndi ma algorithms owongolera kuti achepetse kugwiritsa ntchito mphamvu. Mwachitsanzo, mapampu ena amangotenga mphamvu yayikulu panthawi yoyamba ya inflation kenako amagwira ntchito pamlingo wotsika wa mphamvu panthawi yoyezera.

Ma Valves mu Zowunikira Kupanikizika kwa Magazi

Tsatanetsatane wa Valavu Yolowera: Valavu yolowera nthawi zambiri imakhala valavu yowunikira njira imodzi. Yapangidwa ndi kachipangizo kakang'ono kozungulira kapena mpira komwe kamalola mpweya kuyenda mbali imodzi yokha - kulowa mu cuff. Kapangidwe kosavuta koma kogwira mtima aka kamaletsa mpweya kutuluka kudzera mu pampu, kuonetsetsa kuti cuff imadzaza bwino. Kutsegula ndi kutseka kwa valavu kumayendetsedwa bwino ndi nthawi yogwirira ntchito ya pampu. Mwachitsanzo, pampu ikayamba, valavu yolowera imatsegulidwa nthawi yomweyo kuti mpweya ulowe bwino.

Makina a Valavu Yotuluka: Ma valve otuluka amatha kukhala osiyanasiyana koma ambiri ndi ma valve oyendetsedwa bwino ndi solenoid. Ma valve amenewa amayendetsedwa ndi magetsi ndipo amatha kutseguka ndi kutsekedwa bwino kwambiri. Amakonzedwa kuti atulutse mpweya kuchokera mu cuff pa liwiro linalake, nthawi zambiri pakati pa 2 ndi 3 mmHg pa sekondi imodzi panthawi ya deflation. Liwiro limeneli ndi lofunika kwambiri chifukwa limalola masensa kuzindikira molondola kusintha kwa kuthamanga kwa magazi pamene mtsempha wamagazi ukutseguka pang'onopang'ono, zomwe ndizofunikira kwambiri podziwa kuthamanga kwa magazi kwa systolic ndi diastolic.

Kusamalira ndi Kukhalitsa: Ma valve onse olowa ndi otuluka ayenera kukhala olimba komanso odalirika, chifukwa vuto lililonse lingayambitse kuwerengedwa kolakwika. Opanga nthawi zambiri amalangiza kukonza nthawi zonse, monga kuyeretsa ndi kuyang'anira. Ma valve opangidwa ndi zipangizo zapamwamba kwambiri, monga chitsulo chosapanga dzimbiri kapena pulasitiki yosagwira dzimbiri, nthawi zambiri amakhala ndi moyo wautali komanso amagwira ntchito bwino pakapita nthawi. Nthawi zina, njira zodziyeretsera zokha zimaphatikizidwa mu kapangidwe ka ma valve kuti zisatsekedwe ndi fumbi kapena tinthu tina.

Mwachidule, mapampu ndi ma valve mu zowunikira kuthamanga kwa magazi ndi zinthu zopangidwa mwaluso kwambiri zomwe zimafuna kulondola komanso kudalirika. Kapangidwe kake katsatanetsatane komanso kugwira ntchito bwino ndizomwe zimapangitsa kuti kuyeza kuthamanga kwa magazi masiku ano kukhale kolondola komanso kodalirika, kuteteza thanzi la anthu ambiri.
