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

DC DiaphragmPumps mu Magazi Owunika

Mtundu ndi Zomangamanga: Mapampu omwe amagwiritsidwa ntchito nthawi zambirimapampu ang'onoang'ono a diaphragm. Amakhala ndi diaphragm yosinthika, yomwe nthawi zambiri imapangidwa ndi mphira kapena zinthu zofananira za elastomeric, zomwe zimayenda cham'mbuyo ndikuchotsa mpweya. Diaphragm imamangiriridwa ku mota kapena actuator yomwe imapereka mphamvu yoyendetsa. Mwachitsanzo, mumitundu ina, mota yaying'ono ya DC imathandizira kusuntha kwa diaphragm. Kapangidwe kameneka kamalola kuwongolera molondola kuchuluka kwa mpweya ndi kutulutsa mphamvu.

Kusintha kwa Pressure and Regulation: Kuthekera kwa mpope kutulutsa ndikuwongolera kuthamanga ndikofunikira. Iyenera kukulitsa makapu ku kukanikiza komwe kumayambira pa 0 mpaka kupitilira 200 mmHg, kutengera muyeso wofunikira. Mapampu otsogola ali ndi masensa olowera mkati omwe amayankha ku gawo lowongolera, kuwapangitsa kuti asinthe kuchuluka kwa inflation ndikusunga kuwonjezereka kokhazikika. Izi ndizofunikira kuti mutseke molondola mtsempha wamagazi ndikupeza zowerengera zodalirika.

Kugwiritsa Ntchito Mphamvu ndi Mwachangu: Poganizira kuti zowunikira zambiri za kuthamanga kwa magazi zimayendetsedwa ndi batri, kugwiritsa ntchito mphamvu ya pampu ndikofunikira. Opanga amayesetsa kupanga mapampu omwe amatha kupereka ntchito yofunikira ndikuchepetsa kukhetsa kwa batri. Mapampu ogwira mtima amagwiritsa ntchito mapangidwe okhathamiritsa agalimoto ndikuwongolera ma aligorivimu kuti achepetse kugwiritsa ntchito mphamvu. Mwachitsanzo, mapampu ena amangotenga mphamvu yayikulu panthawi yoyambira ya inflation ndiyeno amagwira ntchito pang'onopang'ono panthawi yoyezera.

Ma valve mu Zowunika za Kuthamanga kwa Magazi

Tsatanetsatane wa Vavu yolowera: Valavu yolowera nthawi zambiri imakhala njira imodzi yokha. Amapangidwa ndi kachingwe kakang'ono kapena kanjira ka mpira komwe kamalola kuti mpweya uziyenda mbali imodzi yokha - kulowa mu cuff. Kapangidwe kosavuta koma kothandiza kameneka kamapangitsa kuti mpweya usatulukenso kudzera pa mpope, kuonetsetsa kuti khafu likufufuma bwino. Kutsegula ndi kutseka kwa valve kumayendetsedwa bwino ndi nthawi yogwiritsira ntchito mpope. Mwachitsanzo, pompayo ikayamba, valavu yolowera imatsegulidwa nthawi yomweyo kuti mpweya uziyenda bwino.

Outflow Valve Mechanics: Mavavu otuluka amatha kusiyanasiyana pamapangidwe koma nthawi zambiri amakhala ndi ma valve a solenoid olondola. Mavavuwa amayendetsedwa pakompyuta ndipo amatha kutseguka ndi kutseka molondola kwambiri. Amawerengedwa kuti atulutse mpweya kuchokera ku khafu pamlingo winawake, nthawi zambiri pakati pa 2 ndi 3 mmHg pamphindikati panthawi ya deflation. Mlingo uwu ndi wofunikira kwambiri chifukwa umalola masensa kuti azindikire molondola kusinthasintha kwa mitsempha pamene mtsempha umatseguka pang'onopang'ono, zomwe ndizofunikira kuti mudziwe kuthamanga kwa magazi kwa systolic ndi diastolic.

Kusamalira ndi Kukhalitsa: Ma valve onse olowera ndi otuluka amafunika kukhala olimba komanso odalirika, chifukwa vuto lililonse lingayambitse kuwerengera molakwika. Kukonza nthawi zonse, monga kuyeretsa ndi kuyendera, nthawi zambiri kumalimbikitsidwa ndi opanga. Mavavu opangidwa ndi zida zapamwamba, monga chitsulo chosapanga dzimbiri kapena mapulasitiki osachita dzimbiri, amakhala ndi moyo wautali komanso amagwira ntchito bwino pakapita nthawi. Nthawi zina, njira zodzitchinjiriza zimaphatikizidwa mu kapangidwe ka valve kuti tipewe kutsekedwa ndi fumbi kapena tinthu tating'ono.

Mwachidule, mapampu ndi ma valve omwe amawunikira kuthamanga kwa magazi ndi zinthu zopangidwa kwambiri zomwe zimafuna kulondola komanso kudalirika. Mapangidwe awo mwatsatanetsatane ndi kagwiridwe kake kake ndi zomwe zimapangitsa kuyeza kwamakono kwa kuthamanga kwa magazi kukhala kolondola ndi kodalirika, kuteteza thanzi la anthu osawerengeka.
