Peristaltic twj tso kua mis: Ib qho pheej yig thiab ntau yam kev hloov pauv kua

A peristaltic twj tso kua mis, los yog Peristaltic Pump ua lus Askiv, yog lub twj tso kua mis hloov pauv zoo uas siv lub raj hloov pauv los thauj cov kua dej. Lo lus "peristaltic" yog los ntawm Greek lo lus "peristaltikos," lub ntsiab lus "contractile thiab propulsive," uas piav qhia txog qhov kev ua haujlwm zoo li qhov kev cog lus ntawm txoj hnyuv. Lub twj tso kua mis muaj lub twj tso kua mis lub cev, lub raj hloov tau yooj yim, lub tshuab tsav, thiab lub tshuab tswj. Nws txoj kev yooj yim hauv kev tsim ua kom yooj yim ntawm kev ua haujlwm thiab kev saib xyuas.

 

Lub hauv paus ntsiab lus ua haujlwm ntawm lub twj tso kua mis peristaltic yog ua raws li cov nyhuv peristaltic. Nyob rau hauv lub twj tso kua mis, ib los yog ntau tshaj chais yog positioned nyob ze rau lub saj zawg zog raj. Raws li lub tshuab tsav tig cov chais, lawv compress lub raj, yuam cov kua dej hauv mus rau pem hauv ntej. Lub compression tsim cov kua dej kaw hauv lub raj, tiv thaiv kev rov qab los ntawm lub raj lub elasticity. Cov txheej txheem no rov ua dua cyclically, ua rau muaj txiaj ntsig thiab ruaj khov hloov pauv dej.

 

Lub twj tso kua mis peristaltic, muab los ntawm Greek lo lus "peristaltia," txhais tau hais tias "kom nkag los yog txav mus tom ntej los ntawm nthwv dej," ua haujlwm los ntawm ntu ntu txuas lub raj hloov pauv. Qhov kev ua no txhawb nqa cov kua dej los ntawm lub raj, ua kom lub cev txav ntawm cov hnyuv hauv tib neeg. Lub twj tso kua mis feem ntau muaj lub twj tso kua mis lub cev, lub raj hloov tau yooj yim, lub tshuab tsav, thiab kev tswj hwm qhov system.   Nyob rau hauv lub twj tso kua mis lub cev, ib tug los yog ntau tshaj rollers yog positioned nyob ze rau lub tubing. Thaum tus tsav mechanism tig cov chais, lawv compress lub raj, tsim kom muaj cov kua dej kaw. Vim lub tubing lub elasticity, cov kua yog thawb mus rau pem hauv ntej yam tsis muaj kev tso cai rov qab. Cov txheej txheem no rov ua dua thaum cov rollers txuas ntxiv tig, ua rau cov kua dej tas mus li thiab pulsatile.

Pheej yig peristaltic twj tso kua mis pom dav siv nyob rau hauv ntau yam kev lag luam vim lawv cov kev ua hauj lwm tshwj xeeb thiab adaptability. Nov yog qee qhov tseem ceeb ntawm daim ntawv thov:
