Isikhathi Esiphephile Sokuthintana Kwesikhumba Nama-Silicone Breast Patches

I. Izilinganiso Eziyinhloko Zobude Besikhathi Esiphephile: Ukusungula Imingcele Ngombono Wezokwelapha

Nakuba kungekho simiso esiphelele sesikhathi esiphephile sokuxhumana kwesikhumba no-ama-patches esifuba e-silicone, ucwaningo lwezokwelapha kanye nokubuka kwezokwelapha kusungule isilinganiso sokuvumelana. Amapulatifomu agunyaziwe njenge-Xiaohe Medical Encyclopedia asho ngokusobala ukuthi isikhathi esinconywayo sokugqoka ama-patches esifuba e-silicone ngabantu abanempilo akufanele sidlule amahora angu-8. Le ndinganiso isekelwe ezintweni ezimbili ezibalulekile:
* **Izidingo Zesikhumba Zomzimba:** Nakuba i-silicone inwebeka, ayiphefumuli kahle. Ukumbozwa okuqhubekayo isikhathi esingaphezu kwamahora angu-8 kungaholela ekuqongeleleni kokujuluka kwendawo, okubangela umswakama ophezulu kakhulu ku-stratum corneum, okulimaza umsebenzi wokuvimbela isikhumba. 15% wabasebenzisi abaqhubekayo bangase babe nokushisa okushisayo noma i-folliculitis.

* **Ingozi Yokucasuka Kwamakhemikhali:** Ama-ester e-Acrylic kungqimba lokunamathela le-patch yesifuba angabangela ukusabela okubambezelekile. Uma ukuthintana okuqhubekayo kudlula amahora angu-12, ingozi yokungezwani komzimba iyanda kathathu, okubonakala njengezimpawu ze-contact dermatitis njenge-erythema nama-papule emaphethelweni e-patch. Izinhlobo ezikhethekile zidinga ukulawula okuqinile isikhathi sokusetshenziswa: Abesifazane abakhulelwe, ngenxa yezinguquko zamahomoni eziholela esikhumbeni esibuthakathaka, belulekwa ukuthi bagqoke ama-patches isikhathi esingaphezu kwamahora ayi-6 njalo, futhi kufanele basebenzise i-adhesive yezinga lezokwelapha engacasuli. Abantu abanesikhumba esibucayi kufanele banciphise isikhathi sibe amahora angu-4-6 futhi benze ukuhlolwa kwesikhumba okuncane ngaphambi kokusetshenziswa kokuqala.

II. Izingozi ezintathu ezinkulu ezifihliwe ezidlula imingcele yokuphepha: Izinto zokwakha kanye nezindinganiso zibalulekile

Iphuzu elibalulekile lesikhathi sokusetshenziswa okuphephile alihlukanisiwe; ukusebenza kahle kwalo kuncike kakhulu ezintweni zomkhiqizo kanye nezindinganiso zokusetshenziswa. Izingozi ezintathu ezifihliwe emakethe yamanje zidinga ukunakwa okuseduze kumakhasimende aphesheya kwezilwandle:

(I) Ukwakheka kwengqimba yokunamathela: Ingozi yempilo engabonakali. Ingqimba yokunamathela, ethintana ngqo nesikhumba, iyona ingozi eyinhloko. Ucwaningo olwenziwe yiYangcheng Evening News lubonisa ukuthi imikhiqizo eminingi etholakala kwezentengiselwano ayinikezi isitifiketi sokunamathela sezinga lezokwelapha. Ezinye izinti ezingaphansi ziqukethe i-formaldehyde, i-lead, nezinye izinsimbi ezisindayo, umzimba womuntu ongenakukwazi ukuzisebenzisa kahle isikhathi eside. Ukusetshenziswa isikhathi eside kungabangela ukungezwani kwesikhumba, ukucasuka kokuphefumula, ngisho nokuncipha kokuzivikela komzimba. Ochwepheshe bezokwelapha bagcizelela ukuthi isihluthulelo sokunquma ukuphepha kwengqimba yokunamathela sisekutheni ngabe isiphumelele yini isitifiketi sezokwelapha—isibonelo, ukusebenzisa i-glue ezwela ukucindezeleka kwezokwelapha ehlangabezana nezindinganiso ze-ISO 10993-1 biocompatibility kunganciphisa ingozi yokungezwani komzimba ibe ngaphansi kuka-0.3%. (II) Ibanga Lezinto: Umehluko obalulekile phakathi kwe-silicone yezinga lezokwelapha kanye ne-silicone yezinga elijwayelekile. Ubumsulwa be-substrate ye-silicone buthinta ngqo umkhawulo ophezulu wokuphepha. I-silicone yezinga lezokwelapha kumele iphumelele ukuhlolwa kwe-cytotoxicity level 0 (engeyona enobuthi) futhi igcine ukuqina kwayo ngemva kokuhlanza ku-121℃. Ama-patches amabele enziwe ngale nto angandisa isikhathi sokugqokwa sibe amahora angu-8-10. I-silicone evamile yezinga lezimboni ingaba nama-filler aphansi (njenge-calcium carbonate enezinsimbi ezisindayo ngokweqile), okungase kubangele ukucasuka kwesikhumba ngisho noma kugqokwa isikhathi esifushane. (III) Ukungqubuzana Kokujwayelekile: Ukuntuleka Kwezindinganiso Zemboni Imboni yamanje yama-patch amabele ihlushwa ukungalungi okuphawulekayo okujwayelekile: ama-30% emikhiqizo asebenzisa kabi amazinga endwangu (njenge-GB/T 30157-2013) ukuhlola izinto ze-silicone, ehluleka ukubhekana nezinkomba zokuphepha kwesikhumba; ama-45% ezinkampani asebenzisa amazinga azo ebhizinisi azenzele wona (njenge-Q/HZLL 002-2004), engenazo imingcele ephoqelekile; ama-25% kuphela emikhiqizo abhekisela ezindinganisweni zomkhiqizo wokuhlanzeka ongasetshenziswa, kodwa ama-patches amabele asetshenziswa kakhulu ngokuphindaphindiwe, okuphakamisa imibuzo mayelana nokusebenza kwale nqubo. Kuyaphawuleka ukuthi indinganiso yeqembu le-T/TTGA 009-2025 “Breast Patches”, eyaqaliswa ngo-Ephreli 2025, idinga ngokusobala ukuthi ama-phthalates kungqimba lokunamathela kanye nezinsimbi ezisindayo ezingakhishwa kumele ahlangabezane nemingcele, futhi okuqukethwe kwe-formaldehyde nezinye izinkomba kumele kuhambisane nezindinganiso ze-GB 18401, okuhlinzeka ngenkomba ehlanganisiwe yokuphepha komkhiqizo. III. Imingcele Yokuphepha Emakethe Yomhlaba Wonke: Izindinganiso Ezibalulekile Zokuthumela Ngaphandle Kumakhasimende aphesheya ngobuningi, imikhiqizo kumele ihlangabezane nemithethonqubo ephoqelekile yemakethe eqondiwe. Lokhu kusekelwa okuyisisekelo kokuqinisekisa ukuphepha isikhathi eside:

Izinkomba Zokuhlola Eziyinhloko Zesifunda Semakethe

Isibonelo, emakethe ye-EU, ama-breast patches angakadluli ukubhaliswa kwezidakamizwa zamakhemikhali ngokomthetho we-REACH, noma ngabe athi “kuphephile ukuwagqoka amahora angu-8,” azobhekana nengozi yokuboshwa kwentela. Amakhasimende athengisa ngobuningi ayelulekwa ukuthi abeke phambili imikhiqizo edlulile isitifiketi se-ISO 10993 sokuhambisana kwezinto eziphilayo kanye nokubhaliswa kwe-FDA ukuze kuncishiswe ingozi yezithiyo zokuhweba.

IV. Iziqondiso Zokuphepha Zokuthenga Nokusebenzisa: Ukudala Inani Kumakhasimende Okugcina

Njengomhlinzeki wezimpahla ezithengiswa ngobuningi, ungaletha inani lokuphepha futhi uthuthukise ukwethenjwa kwamakhasimende ngalezi zindlela ezilandelayo:

(I) Izinto Ezintathu Ezibalulekile Zokukhetha Umkhiqizo
* Isitifiketi Sezinto Ezibalulekile: Kudingeka ukuthi amafektri ahlinzeke ngobufakazi bezinto zokusetshenziswa ze-silicone zezinga lezokwelapha (njengochungechunge lwe-Dow Corning Silastic®) kanye nemibiko yesitifiketi se-adhesive yezinga lezokwelapha;
* Ukuthobela Izindinganiso: Beka phambili imikhiqizo ehambisana nezindinganiso ze-T/TTGA 009-2025 noma ze-ISO 10993, ugweme ukwamukelwa kwezindinganiso ezizichazayo yizinkampani ngazinye;
* Ukuhlolwa Kokusebenza: Ukuhlolwa kokuthatha amasampula kufanele kwenziwe ngamandla okukhishwa kwesendlalelo sokunamathela (okunconywayo ≥1.5N/cm) kanye nokuphefumuleka (izinga lokudlulisa umhwamuko wamanzi ≥500g/(m²・24h)) ukuze kulinganiswe ukunamathela nokuphepha. (II) Iziphakamiso Zezimo Zokusetshenziswa Komsebenzisi Wokugcina
Nikeza amakhasimende imihlahlandlela yesikhathi sokusetshenziswa eqondene nesimo esithile ukuze kuthuthukiswe ukusetshenziswa komkhiqizo:
Ukuhamba Kwansuku Zonke: ≤ amahora angu-8, sebenzisa nemikhiqizo ephefumulayo (njengaleyo enezimbobo zokungenisa umoya zezinyosi);
Imicimbi Ekhethekile (isb., imishado, amadili): ≤ amahora ayi-10, kunconywa ukuthi kususwe imizuzu eyi-15 ukuze kungene umoya;
Izimo Zokushisa Okuphezulu/Zemidlalo: ≤ amahora angu-4, khetha amamodeli angangeni manzi futhi angangenisi umjuluko anezinto zokupholisa engqimbeni yokunamathela.
Futhi, khumbuza abasebenzisi bokugcina: Ngemva kokusebenzisa ngakunye, hlanza ungqimba lokunamathela ngesihlanzi esingathathi hlangothi, uvumele ukuthi lome ngokwemvelo ngaphambi kokugcina, futhi ugweme ukukhanya kwelanga okuqondile ukuze uvimbele ukuguga kwezinto—i-silicone yokuguga ikhipha izinto ezicasulayo ezingaphezu kwezikhathi ezintathu.

V. Izitayela Zemboni: Izindinganiso Zokuphepha Zikhuthaza Ukuthuthukiswa Komkhiqizo

Njengoba ulwazi ngempilo yabathengi lukhula, ukusetshenziswa kwesikhathi ngokuphephile sekuyinto ebaluleke kakhulu ekuncintisaneniimikhiqizo ye-breast patchIzinkampani ezihamba phambili zidlula ezinkingeni zokuphepha ngokusebenzisa ubuchwepheshe obusha: Ngokuphathelene nezinto zokwakha: Kusetshenziswa irabha ye-silicone eqinisiwe ngeplatinum esikhundleni serabha ye-silicone eqinisiwe nge-peroxide, okunciphisa insalela ye-VOC kusuka ku-≤10ppm kuya ku-≤2ppm; Ngokuphathelene nesakhiwo: Ukuthuthukiswa kwezinto ezihlanganisiwe ze-“silicone + ulwelwesi oluphefumulayo” kuthuthukisa ukuphefumula ngo-40% futhi kwandisa isikhathi sokuphepha sibe amahora ayi-12; Ngokuphathelene nokuhlola: EN 1811:2022 ukuhlolwa kokukhishwa kwe-nickel kanye nokuhlolwa kokukhishwa kwe-nanoparticle kwe-ISO 18562-4 kwethulwa, okuhlanganisa ububanzi obanzi bezilinganiso zokuphepha.
