Indlela Yokwenza oftalmotonometrii izinsimbi. Tonometer Maklakova: idivayisi isicelo futhi

Ingcindezi ngaphakathi amakhamera iso kunqunywa umehluko velocity of inflow futhi outflow ka therethrough ketshezi. Asetshenziswa umkhuba izindlela zokwelashwa tonometry (ingcindezi) kukhona engaqondile futhi unike tonographic ingcindezi inkomba.

Yokukala ingcindezi intraocular ibaluleke kakhulu sitholakele glaucoma kanye nokunakekelwa kwamehlo ngesikhathi esifanele iziguli.

Tonometer Maklakova e oftalmotonometrii

Esikhathini zamehlo yasekhaya kuvame kakhulu ukuba kusetshenziswe izindlela non-contact tonometer futhi intraocular ingcindezi nesilinganiso ngu Maklakov. Lesi sakamuva kwahlongozwa ngo-1884, futhi ngo-umkhuba ezibanzi Eya phambili kancane kamuva.

Tonometry ku Maklakov sifushane ukufakwa Sinker (tonometer) kwi-cornea kanye ukuthola zeminwe contact ebusweni. Ngo isikwele wakhe Imisa ingcindezi intraocular.

Ngaphezu CIS, indlela kabanzi lisetshenziswe China.

tonometer Ocular Maklakova - ephelele futhi idivayisi ithuluzi

Tonometer ikhithi kuhlanganisa:

• ezimbili cylindrical Sinker isisindo 10 g, enwetshiwe enisemikhawulweni nge flat ekupheleni ubuso;
• Umnikazi for izilinganiso, lapho kanyekanye ukulungisa ezimbili Sinker;
• 3 Ukulinganisa umbusi ukulinganisa ububanzi we ukuphrinta umugqa noma uSolwazi B. Polyak;
• icala.

Imithwalo nephupho ngaphakathi, aqukethe silinganiso phambili. abakuphela kwabo evele zakhiwe ingilazi Frosted, evumela nombala ubamba isixazululo staining.

Umnikazi kuyadingeka, ukuze ngesikhathi nesilinganiso iminwe ungawakhi ingcindezi ngokweqile phezu tonometer ka Maklakov.

Indlela ukusebenza tonometer

Ngaphambi kokuba uqale udinga ukuhlola isimo tonometer. Ukwephulwa ekupheleni ezisekelweni kungalimaza ubuqotho cornea lesiguli. Ngaphezu kwalokho, lo mbhalo kufanele kube lula ukuhamba umnikazi we-gap.

Icubungula tonometers Maklakova ngaphambi kokusebenzisa liqukethe bezihlikihla utshwala pads, okwathi ngemva kwalokho kwensimbi omisiwe for 15-30 imizuzwana.

Sterilisation by abilayo e-2% baking soda imizuzu 30 isixazululo wenziwa kuphela amacala ngqangi:

• lapho iziguli wahlola izimpawu ukuvuvukala conjunctiva;
• esimweni usongo ukwehlukana keratoconjunctivitis ezibangelwa amagciwane.

Njengoba tonometer Maklakova liphindele, by abilayo emanzini Ungangenela. Ukuze oftalmotonometrii Imiphumela ungazange zaziphendukezelwe ngenxa mass ushintsho iyunithi engakapheli amahora noma ngaphezulu wawoma gauze oyinyumba.

Paint isicelo ku- Maklakova tonometer, is yashaywa ibe ingxube glycerol namanzi Colloid esiliva (esiliva colloidal albumin). Kungenzeka ukusebenzisa colorants Bismarck onsundu ngokuphaphathekile noma abe methylene okwesibhakabhaka. Ukuze upende enamathela amapuleti usebenzisa inki pad noma idluliselwe iconsi udayi okulungiselelwe ngenduku ingilazi bese triturated nge swab ukotini. Indlela yokugcina kuphephile ngokuya nalolubhubhane.

Izindlela cwaningo ingcindezi intraocular tonometer Maklakova

Ngaphambi tonometry iso izinzwa esigulini. Ngenxa yale njongo, ngaphakathi komgodlana conjunctival kabili ne esingaba imizuzu 2 safaka dikaina isixazululo. Abagulayo phakathi instillation ihlanganisa naphakade.

Ngokulandelayo, udokotela noma unesi kuzothatha izenzo ngendlela elandelayo:

1. Sula tonometer Maklakova utshwala, basuke omisiwe.
2. On isayithi tonometer sisetshenziswa ungqimba ezondile upende.
3. Isiguli elala phezu kombhede ngaphandle umcamelo, kwesilevu iphakame kancane, amehlo silungise phezu index ngomunwe yezandla yakhe eyeluliwe up. I Ingcenye ephakathi yesigaba cornea kumele okungenani endaweni efanayo ovundlile.
4. Iminwe yesandla esisodwa umcwaningi ekwandiseni iso umqhewu ukuba Isivalo musa acindezele inhlamvu yeso.
5. Nge Ngakolunye uhlangothi esebenzisa umnikazi kusukela phezulu phansi tonometer Maklakova endaweni ezinemibala phakathi nendawo cornea. Sinker kufanele kube phansi nobuso ngokuphelele ngenxa yesisindo somzimba wakhe.
6. Khona-ke le mpahla ngokushesha sithathe futhi wenze uphawu ephepheni, oswakanyiswe utshwala.
7. Ucwaningo liphindwe iso yesibili.
8. Amehlo isiguli bahlanza kusukela nosawoti upende safaka Albucidum.

Phakathi ukwehlisa tonometer ku-cornea we upende endaweni oxhumana naye zakhukhula ngezinyembezi. Ethonya ewumphumela indandatho.

Ukuhunyushwa imiphumela Maklakov oftalmotonometrii

I ububanzi we umbuthano yokukhanya eshidini kuyinto ezilinganiselwe ngezinga aba ka-cornea phakathi nesifundo. Ngakho, ayanda ingcindezi, uyinki kancane izosuswa futhi, ngokufanelekile, ngaphansi endaweni ukukhanya weminwe.

umbusi esobala kulinganiswa ubukhulu esifundeni ukukhanya. Umcwaningi kufanele ngiyibeke izikali phansi ukugwema ukuhlanekezela. Ezenye esikalini isikhulisi Binocular. Zifakwe umugqa isikali ivumela ukudluliswa ngokushesha nomphumela amamilimitha angu mercury.

Lapho yokulinganisa umugqa evamile (0.1 mm), isilinganiso ingcindezi esibaliwe ratio isisindo tonometer: engaba zeminwe yisikwele ngenani "Pi" futhi ngenxa yesisindo ethize mercury (13,6).

Jwayelekile ingcindezi intraocular ngu Maklakov kuyinto 18-26 mm HG ububanzi. Art.

Ukulinganiselwa netimphawu indlela

Akunconyelwe ukusetshenziswa tonometry ku Maklakov kulezi zimo ezilandelayo:

• ngemva othola ukuhlinza yeso;
• ukusabela iguliswa izinzwa;
• e ukuvuvukala amehlo futhi izikhumba.

Maklakova Tonometer phezu inhlamvu yeso has a ingcindezi obukhulu kunobukaJohane kwezinye izindlela, ngokulandelana, umphumela izinga uhamba ngendlela enkulu. Ukuze uqhathanise, evamile ocular ingcindezi Goldmann kuyinto 9-21 mm HG. Art. Ngakho-ke, ukuqhathanisa imiphumela etholwe izindlela ezahlukahlukene, ngeke lesifanele.
