Ukuqonda Amandla Okulwa Neentsholongwane Ezisetyenziswa Kwizikhenkcezisi Zesibhedlele Ezilahlwayo
Amakhethini esibhedlele alahlwayozibalulekile ekuthinteleni ukusasazeka kwezifo kwiindawo zonyango. Ezi khethini ezilahlwayo, ezikwaziwa ngokuba zikhethini ezisetyenziswa kanye, zineempawu ezikhethekileyo zokulwa neentsholongwane ezinegalelo ekugcineni imeko-bume icocekile. Ngokusebenzisa iikhethini zesikrini ezilahlwayo, izibonelelo zinokuphucula kakhulu ukhuseleko lwezigulane kwaye zinciphise umngcipheko wosulelo olufunyanwa esibhedlele. Ukusetyenziswa kweekhethini ezilahlwayo amakhethini esibhedlele, kuqukaamakhethini eekhabhinethi zesibhedlele, iqinisekisa umgangatho ophezulu wococeko kwiindawo zonyango.
Izinto ezibalulekileyo ekufuneka ziqwalaselwe
- Amakhethini esibhedlele alahlwayo anceda ekuthinteleni ukusasazeka kwezifo ngokubonelela ngomqobo ococekileyo kumguli ngamnye.
- Ukutshintshwa rhoqo kwezi khethini kubalulekile ekugcineni ucoceko kunye nokunciphisa umngcipheko wongcoliseko oluvela kwezinye iindawo.
- Ukusebenzisa amakhethini alahlwayo kunokonga ixesha nemali ngokunciphisa iindleko zokuhlamba impahla nokuqinisekisa ukuba indawo ehlala icocekile.
Izinto ezisetyenziswa kwiikhethini zesibhedlele ezilahlwayo
Iintlobo zamaLaphu
Amakhethini esibhedlele alahlwayo asebenzisa kakhulu izinto ezikhaphukhaphu ezenzelwe ukusetyenziswa kanye. Amalaphu aqhelekileyo aquka:
| Uhlobo lwezinto | Inkcazo |
|---|---|
| I-Polypropylene (PP) | Le yeyona nto ixhaphakileyo. Ayinamanzi, yenza umqobo kumathontsi aphuma emoyeni ngelixa ihlangabezana nemigangatho yokhuseleko lwezonyango. |
| I-Polyester (PET) Composite | Le laphu inika amandla aphezulu okutsalwa. Idibanisa ukuphefumla kwe-PP kunye nokumelana nokukrazuka kwe-PET. |
| I-Polyethylene (PE) Egqunywe | Le nto inika umaleko ongenakungena emanzini ofanelekileyo kwiindawo ezinongcoliseko olukhulu. Ihlangabezana nemigangatho ye-ASTM yokumelana nezifo. |
Ukukhetha ezi zinto kubalulekile ekulawuleni usulelo. Umzekelo, i-polypropylene kunye ne-polyester zilula, nto leyo eyenza kube lula ukuziphatha nokuzifaka. Nangona kunjalo, ukubhitya kwazo kunokubeka emngciphekweni ubumfihlo, njengoko zivumela ukukhanya kudlule, nto leyo eyenza ukuba iintshukumo zesigulana zibonakale.
Iingubo kunye nonyango
Ukuphucula iimpawu zazo zokulwa neentsholongwane, amakhethini esibhedlele alahlwayo adla ngokufakwa iingubo ezikhethekileyo kunye nonyango. Ezi ngubo ziqulethe ii-biostatic agents eziphazamisa imisebenzi yeeseli zebhaktiriya, zithintela ukukhula kwazo ngempumelelo. Izifundo zibonise ukwehla okukhulu kongcoliseko lwebhaktiriya kumphezulu wekhethini emva kokufakwa kweenguqulelo ze-antimicrobial. Umzekelo, ngaphambi kokusetyenziswa kweengubo ze-antimicrobial, ungcoliseko oluqhelekileyo lwebhaktiriya lwalulinganiswa kwi-32.6 CFUs. Emva kokusetyenziswa, eli nani lehle kakhulu laya kwi-0.56 CFUs kuphela.
Ezi mpahla zihlala ziquka izinto ezifana ne-didecyl dimethyl ammonium chloride okanye i-polysiloxane. Ezi zinto zisusa okanye zinciphise kakhulu iintsholongwane ze-Gram-negative kunye ne-Gram-positive kumphezulu weekhethini. Oku kunciphisa umngcipheko wongcoliseko oludluliselwa ngesandla kwizigulana nakubasebenzi bezempilo.
Ubuchule bakutshanje kwisayensi yezinto ezibonakalayo buphucule ngakumbi iipropati zokulwa nentsholongwane kwiikhethini zesibhedlele ezilahlwayo. Umzekelo, iMicrillon microfibre, isongezo sepolymer esinokutshajwa kwakhona, siphucula iipropati zokulwa nentsholongwane ngokususa iintsholongwane xa zidibana. Olu phuculo lubonisa ukususwa kwe-antibacterial eyi-100% kwiintsholongwane ezifana neStaphylococcus aureus (MRSA) kunye ne-E. coli 0157:H7.
Iimpawu ze-Antibacterial zeKhenethi zeSibhedlele eziLahlwayo
Iindlela Zokusebenza
Amakhethini esibhedlele alahlwayo athintela ukukhula kweentsholongwane ngeendlela ezahlukeneyo ezisebenzayo. Okokuqala, asusa ngokoqobo indawo yokugcina iintsholongwane, nto leyo enceda ekunciphiseni ubukho beentsholongwane kwiindawo zonyango. Oku kususwa ngokoqobo kubalulekile kuba kunciphisa ukwakheka kweentsholongwane ngokuqinisekisa ukuba amakhethini atshintshwa rhoqo. Ngokuphepha ukuxhomekeka kunyango lweekhemikhali, la makhethini athintela imiba efana nokunciphisa ukusebenza kakuhle kunye nokuxhathisa iintsholongwane okuhlala kuhamba neekhemikhali zokulwa neentsholongwane.
Iindlela eziphambili ziquka:
- Umqobo Womzimba: Izinto ezikhaphukhaphu ezisetyenziswa kwiikhethini zesibhedlele ezilahlwayo zisebenza njengomqobo kumathontsi aphuma emoyeni, zithintela ukusasazeka kwezifo ezibangelwa ziintsholongwane.
- Ukutshintshwa rhoqo: Ukutshintsha amakhethini rhoqo kuqinisekisa ukuba naluphi na ungcoliseko olunokubakho lweentsholongwane luyasuswa, nto leyo egcina imeko-bume icocekile kwizigulana nakubasebenzi bezempilo.
- Iingubo ze-Antimicrobial: Amakhethini amaninzi alahlwayo aneengubo ezikhethekileyo eziphazamisa ukusebenza kweeseli zebhaktheriya, nto leyo ethintela ukukhula kwazo ngempumelelo.
Ezi zenzo zidibeneyo zinciphisa kakhulu umngcipheko wokosuleleka kwiindawo zonyango.
Uvavanyo kunye neMigangatho
Ukuqinisekisa ukusebenza kakuhle kwamakhethini esibhedlele alahlwayo, iiarhente zomthetho ziphumeza uvavanyo oluqatha kunye nemigangatho. Olu vavanyo luvavanya iipropati zokulwa neentsholongwane zamakhethini, luqinisekisa ukhuseleko lwawo kunye nokusebenza kwawo ngaphambi kokuba afike kwiindawo zonyango.
Uvavanyo luhlala lubandakanya:
- Ukuchonga iintsholongwaneAbaphandi bafumanisa iintsholongwane ezibalulekileyo ezikhoyo kwiindawo zempilo.
- IiYunithi Zokwenza Iikoloni (ii-CFU): Iibhaktheriya zizonke zibalwa njengee-CFU ukuze kulinganiswe amanqanaba ongcoliseko.
- Uvavanyo lweLebhu: Umsebenzi wee-antimicrobial we-curtain swatches uvavanywa kwiintsholongwane ezahlukeneyo, kunye nemilinganiselo ebhalwe njengendawo yokuthintela kunye nokuthintela ukudibana.
Umzekelo, uphando luvavanye amayeza okubulala iintsholongwane alishumi elinesine alahlwayo Amakhethini Obumfihlo kwiyunithi yokhathalelo oluphezulu. Iziphumo zibonise ukuba la makhethini asebenze kakuhle kakhulu kwiintsholongwane ezahlukeneyo, kuquka:
| Iintsholongwane |
|---|
| I-Acinetobacter baumannii |
| I-Enterococcus faecalis |
| I-Enterococcus hirae |
| I-Escherichia coli |
| I-Klebsiella pneumoniae |
| I-Pseudomonas aeruginosa |
| I-Salmonella typhimurium |
| MR Staphylococcus aureus |
Ngaphezu koko, amakhethini esibhedlele alahlwayo avavanywa ngokwemigangatho ukuze kulinganiswe ukusebenza kwawo okulwa neentsholongwane. Umzekelo, iimvavanyo ezifana ne-ISO 20743 zibonisa ukwehla kwe-log ye-3 (ukwehla kwe-99.9%) kubukho bebhaktheriya. Ezinye iimvavanyo zibonisa ukuba iingubo ze-quaternary ammonium zinokufikelela ekunciphiseni kwe-CFU ye-98–100% kwiiyure ezine emva kokudibana.
Iiarhente zomthetho zivavanye ezi khethini ngokusekwe ekuthobeleni imithetho yendawo, yelizwe, neyesizwe, kuquka nezo zibekwe yiJoint Commission kunye ne-CMS. Abavelisi kufuneka babonise ukusebenza kakuhle kweempawu zokulwa neentsholongwane ngokuchasene neentsholongwane ezithile ukuze bafumane imvume ye-FDA. Le nkqubo iqinisekisa ukuba iikhethini ziyahlangabezana nemigangatho yokhuseleko kunye nokusebenza kakuhle, kubandakanya ukuhambelana neearhente zokucoca kunye nokuqina.
Ukuthelekisa namakhethini emveli

Ngokwahlukileyo koko, amakhethini emveli anokuhlala iminyaka elishumi xa ehlanjwa ngendlela efanelekileyo, kodwa afuna ukulungiswa okukhulu.
Amakhethini elaphu lendabuko afuna ukususwa, ukuhlanjwa, kunye nokufakelwa kwakhona, nto leyo enokuba yindleko kwaye ifuna umsebenzi omninzi. Izibhedlele kufuneka zilandele ishedyuli yokucoca engqongqo, nto leyo ekhokelela ekulibazisekeni kokhathalelo lwezigulane. Amakhethini alahlwayo anokutshintshwa ngokukhawuleza ngaphandle kokuphazamisa imisebenzi yemihla ngemihla, ukuqinisekisa ukuba umsebenzi usebenza kakuhle.
Ingxelo epapashwe yi-American Journal of Infection Control ifumanise ukuba ngaphezulu kwe-90% yamakhethini kwiindawo zonyango angcoliswa kwiveki enye emva kokuba exhonywe kwakhona. Olu lwazi lugxininisa imfuneko engxamisekileyo yezisombululo ezisebenzayo zokulwa neentsholongwane ezifana namakhethini alahlwayo.
Ukusebenza kakuhle kweendleko
Xa kuvavanywa ukusebenza kakuhle kweendleko, amakhethini asesibhedlele alahlwayo adla ngokuba luncedo kakhulu kwixesha elifutshane. Aphelisa iindleko zokuhlamba impahla ezinxulumene namakhethini emveli, anokuqokelelana kakhulu ngokuhamba kwexesha.
- Iikhethini zesibhedlele ezilahlwayo zihlala zibiza malunga ne-$25.00 ngeyunithi nganye, ngelixa iindleko zonyaka zokugcina iikhethini eziphinda zisetyenziswe zinokufikelela malunga ne-$25,000 ngenxa yeendleko zokuhlamba impahla.
- Nangona amakhethini aphinda asetyenziswe anexabiso eliphezulu lokuthenga ekuqaleni, anokukhokelela ekongeni ixesha elide. Inqanaba lokwamkeleka kwamakhethini aphinda asetyenziswe limalunga neminyaka eyi-2.5, emva koko konge kuqala.
