Je! Dialyzer inaweza kutumika tena kwa matibabu ya hemodialysis?

Dialyzer, a vital consumable for kidney dialysis treatment, uses the principle of a semi-permeable membrane to introduce the blood from the renal failure patients and dialysate into the dialyzer at the same time, and making the two flow in opposite directions on both sides of the dialysis membrane, with the help of the two sides solute gradient, osmotic gradient, and hydraulic pressure gradient. Utaratibu huu wa utawanyiko unaweza kuondoa sumu na maji kupita kiasi kutoka kwa mwili wakati unajaza vitu vinavyohitajika vya mwili na kudumisha usawa wa elektroni na asidi-msingi.

Dialyzers are mainly composed of support structures and dialysis membranes. The hollow fiber types are used most in clinical practice. Baadhi ya hemodialyzers imeundwa kuwa inayoweza kutumika tena, na ujenzi maalum na vifaa ambavyo vinaweza kuhimili usafishaji na sterilizations nyingi. Meanwhile, disposable dialyzers must be discarded after use and can not be reused. However, there has been controversy and confusion about whether dialyzers should be reused. We will explore this question and provide some explanation below.

Ingawa sababu nyingi husababisha ugonjwa wa matumizi ya kwanza, kama vile disinfectant ya ethylene oxide, nyenzo za membrane, cytokines zinazozalishwa na mawasiliano ya damu ya membrane ya dialysis, nk, bila kujali sababu, uwezekano wa tukio utapungua kwa sababu ya matumizi ya mara kwa mara ya dialyzer.

Baada ya kutumia dialyzer, safu ya filamu ya protini imeunganishwa na uso wa ndani wa membrane, ambayo inaweza kupunguza athari ya filamu ya damu inayosababishwa na dialysis inayofuata, na kupunguza uanzishaji wa kukamilisha, uharibifu wa neutrophil, uanzishaji wa lymphocyte, uzalishaji wa microglobulin, na kutolewa kwa cytokine.

The clearance rate of creatinine and urea does not decrease. Matumizi ya dialyzers iliyotumiwa tena na formalin na hypochlorite ya sodiamu iliyoongezwa inaweza kuhakikisha kuwa viwango vya kibali vya vitu vya kati na vikubwa vya Masi (Vital12 na inulin) vinabaki bila kubadilika.

Hakuna shaka kuwa utumiaji wa dialyzer unaweza kupunguza gharama za utunzaji wa afya kwa wagonjwa wa figo na kutoa ufikiaji bora lakini wa bei ghali zaidi wa hemodialyzers

Diski ya asidi ya peracetic itasababisha kuharibika na mtengano wa membrane ya dialysis, na pia kuondoa protini zilizohifadhiwa kwenye membrane kwa sababu ya matumizi ya mara kwa mara, na kuongeza uwezekano wa uanzishaji wa kukamilisha. Formalin disinfection can cause Anti-N-antibody and skin allergies in patients

(3) Utendaji wa dialyzer unashawishiwa.
Baada ya dialyzer kutumiwa mara kadhaa, kwa sababu ya protini na damu zinazozuia vifurushi vya nyuzi, eneo linalofaa hupunguzwa, na kiwango cha kibali na kiwango cha ultrafiltration kitapungua polepole. The common method to measure the fiber bundle volume of a dialyzer is to calculate the total volume of all fiber bundle lumens in the dialyzer. If the ratio of the total capacity to the brand-new dialyzer is less than 80%, the dialyzer cannot be used.

Kwa msingi wa uchambuzi hapo juu, kusafisha na disinfection kunaweza kutengeneza mapungufu ya kutumia tena dialyzers kwa kiwango fulani. Dialyzer inaweza kutumika tu baada ya kusafisha na taratibu za disinfection na vipimo vilivyopitishwa ili kuhakikisha hakuna kupasuka kwa membrane au blockage ndani. Tofauti na urekebishaji wa mwongozo wa jadi, utumiaji wa mashine za kuchakata moja kwa moja za dialyzer huanzisha michakato iliyosimamishwa ndani ya urekebishaji wa dialyzer ili kupunguza makosa katika shughuli za mwongozo. Mashine inaweza suuza kiotomatiki, disinfect, mtihani, na AFFUSE, kulingana na taratibu na vigezo, ili kuboresha athari za matibabu ya dialysis, wakati wa kuhakikisha usalama wa mgonjwa na usafi.
