Nzira ye ophthalmotonometry nezviremba. Tonometer Maklakov: device uye shanduro

Kushingaira mukati memakamuri eziso kunotsanangurwa nemusiyano muyero wekuperera nekubuda kwechirwere kubva kwavari. Nzira dze tonometry dzinoshandiswa mumakiriniki (zviyero zvinoshandiswa) zvinoreva nzira dzisinganzwisisi uye dzinopa tonometric index yezvinetso.

Kuyera kwepisocular pressure kunonyanya kukosha kwekuongororwa kwe glaucoma uye panguva yakakodzera ophthalmic kutarisira varwere.

Tonometer Maklakov mu ophthalmotonometry

Mune mafuro ophthalmology, nzira dzinowanzoshandiswa kushandiswa pasina tonometry uye kuenzaniswa kwepisocular pressure maererano neMaklakov. Iyo yekupedzisira yakarongedzwa muna 1884, uye yakapinda mumashandisirwo akajeka kwenguva pfupi gare gare.

Tonometry maererano neMaklakov inowanikwa muchinguva chiduku chekugadzirisa uremu (tonometer) pamakona eziso uye kuwana chinyorwa chekubatana pamusoro. Nharaunda yekupraocular pressure inosarudzwa nenharaunda yayo.

Mukuwedzera kune ndima yeCIS, iyo nzira inowanzoshandiswa kuChina.

Tonometer yeziso Maklakova - kukwana uye chigadzirwa chechigadzirwa

Nheyo ye tonometer inosanganisira:

• Zviratidzo zviviri zvemagetsi zve 10 g muhomwe, zvinowedzera kumagumo nechiso chepamusoro zviso;
• Iko rine chiyero chekuyera, umo zvese zviyero zvinogona kugadzirirwa pamwe chete;
• 3 miyero yekuyera yekuenzanisa kupenya kwechinyorwa kana mutongi wePurofesa B. Polyak;
• Case.

Zvitakura zviri mukati mawo mukati, zvine chekutakura mumiririri. Kuguma kwavo kunogadzirwa nefriji yakazara, iyo inobvumira kuti inki yekugadzirisa ive yakachengetedzwa zvakafanana.

Muchengeti anodikanwa kuitira kuti panguva yezviyero neminwe yako iwe hausi kuwedzera kudzvinyirira kuMaklakov tonometer.

Mirayiridzo yekushanda ne tonometer

Usati watanga basa, zvakakosha kutarisa mamiriro e tonometer. Kuputsa kuvimbika kwemagumo kunogona kukuvadza konea yemeso omurwere. Mukuwedzera, cylinder inofanira kufamba nyore nyore muchengeti wemuiti.

Kurapa kweMaklakov tonometers kusati kwashandiswa kunosanganisira kubvisa nzvimbo nedoro, mushure mokunge chigadzirwa chacho chakaoma kwemaminitsi 15-30.

Kusvibiswa nekubika mune 2% solution yekubika soda kwemaminitsi makumi matatu kunowanikwa chete mumamiriro ekuda zvakanyanya:

• Apo murwere ane zviratidzo zvekuvhiringidzika kwegunjunctiva akaongororwa;
• Muchiitiko chekutyisidzira mubazi reviral keratoconjunctivitis.

Sezvo Maklakov tonometer isati yakasimbiswa, mvura inogona kubika kana inenge yabikwa mauri. Kuchengetedza kuti migumisiro ye ophthalmotonometry haina kukanganiswa pamusana pekuchinja muhukuru hwechigadzirwa, yakaomeswa kweawa imwe kana kupfuura pane yakashata gauze pad.

Iyo pende yakashandiswa kuMaklakov tonometer ndeye collargol (colloidal siri ne albumin), iyo inowanikwa musanganiswa glycerin nemvura. Zvinogoneka kushandisa dyes bismarck-brown kana methylene bluu. Kuti ufukidze mahwendefa neinki, shandisa padhi rakadhindwa kana kutamisa donhwe reja rakagadzirwa nehuro yegirazi, uye wobva washaya nekotoni swab. Nzira yekupedzisira ndiyo yakachengeteka muurongwa hwehutachiona.

Iyo nzira yekudzidza intraocular pressure ne Maklakov tonometer

Pamberi pe tonometry, maziso omurwere anoremekedzwa. Nokuda kwechikonzero ichi, mhinduro ye dicaine inowedzerwa kugadziriro yejunjunctival kaviri pamaminitsi maviri. Murefu pakati pekudzivirira anofukidza maziso ake.

Uyezve, chiremba kana mukoti anoita zvinotevera:

1. Kuchenesa kweMaklakov's tonometer nedoro inogadzirwa, iyo yakaoma.
2. Ivhu rakatetepa yepende rinoshandiswa kune nzvimbo ye tonometer.
3. Murwere anorara pamubhedha asina mutsamiro, achisimudza zvimedu zvake, anogadzirisa kutarisa pamuromo wechinyorwa chebasa rake rakatambanudzwa. Icho chikamu chepamusoro che cornea chinofanira kunge chiri panzvimbo yakanyanyisa.
4. Neminwe yoruoko rumwe, muongorori anowedzera mucheche wemaziso kuitira kuti maziso asati ashingaira paziso reziso.
5. Neimwe rutivi, kushandisa kambani, Maklokov tonometer inoderedzwa nepaduru yakavara pakati pekornea. Gruzik inofanira kuwira zvakakwana paziso nezvose zvinorema.
6. Zvadaro, mutoro wacho unokurumidza kusimudzwa uye chinyorwa chinogadzirwa papepa yakanyorowa nedoro.
7. Chidzidzo chinodzokororwa kune ziso rechipiri.
8. Meso omurwere anogezwa kubva kune dhayi ine saline uye Albucidum inoputirwa.

Munguva yekuderera kwe tonometer pane cornea, pende iri paunosangana nayo inoshambidzwa kubva nekubvaruka. Somugumisiro, pfungwa yacho ndeyendori.

Tsanangudzo yemigumisiro ye ophthalmotonometry maererano neMaklakov

Iyo yakareba yechitenderera chechiedza pamusoro pekufungidzira inokwana kusvika pamwero we flattening ye cornea panguva yekuongorora. Saizvozvowo, iyo yakasimudza kukanganiswa, iyo pani shoma ichabviswa uye, maererano naizvozvo, nzvimbo shomanana yekudhinda.

Mutongi akajeka anoyera kubwinya kwechiedza. Mutsvakurudzi anofanira kuzviisa pasi kuti arege kupotsa. Chigumisiro chacho chinoongororwa kuburikidza nezwi binocular. Shanduro inoshandiswa pamutongi inokubvumira kuti ushandure pakarepo chigadziro mu millimeters ye mercury.

Kana uchitaridzwa nemutongi wenguva dzose (kusvika ku 0.1 mm), kuverenga kunomirirwa sechiyero kusvika kuhukuru hwe tonometer: chikamu chemairasi ekudhindwa kune nhamba ye "Pi" uye kukwana kwe mercury (13.6).

Chimiro chekumanikidzwa kwameso maererano neMaklakov ndiyo nguva 18-26 mm Hg. Art.

Kukanganisa uye zvinhu zvemuitiro

Hazvikurudzirwi kushandisa tonometry maererano neMaklakov mumatambudziko anotevera:

• Mushure mekuvhiyiwa paziso reziso;
• Izvo zvinokonzera zvinoshandiswa kugadziriswa kune anesthetic;
• Kuvhiringidza kweziso nemakumbo.

Tonometer Maklakova ine paziso reziso, iro rinodarika ichi chimiro mune dzimwe nzira, zvakatarisana, chikonzero chechimiro chinoshandiswa kune rumwe rutivi. Kuenzanidza, iyo inowanzovhara maziso maererano neGoldman is 9-21 mm Hg. Art. Nokudaro, kuenzanisa kwemigumisiro yakawanikwa nenzira dzakasiyana hakuzove yakarurama.
