Description

Področje tehnike
Izum spada v področje tehnike medicinskih injekcijskih igel. Po mednarodni patentni klasifikaciji /4. izdaja/ ga uvrščamo v razred A 61 M 5/52.
Tehniški_groblem
Izum rešuje tehniški problem zaščite medicinskega osebja pred nehotenim vbodom injekcijske igle.
Stanje tehnike
Spričo naglega širjenja nalezljivih bolezni, ki so pri današnjem stanju medicinske vede neozdravljive, pomeni vsak nehoten vbod z uporabljeno medicinsko iglo veliko nevarnost okužbe.
Tej nevarnosti so izpostavljeni tako tisti, /ki dajejo injekcije pacientom, kakor tudi oni, ki uporabljene igle odnašajo na razkuževanje, odnosno uničenje.
Znana je rešitev tega problema s pomočjo meha, ki obdaja injekcijsko iglo za enkratno uporabo. Rešitev je opisana a reviji Življenje in tehnika 5/89. Slabe strani te rešitve so poleg relativno visoke cene še velike mere, ki otežujejo manipulacijo 2pis_rešitve
Rešizev zastavljenega tehniškega problema po izumu je prikazana na priloženi sliki.
Injekcijsko iglo obdaja varovalni ščitnik, ki ga sestavljajo naslednji medsebojno spojeni deli: spodnji del 1 z utorom 2, vzmet 5, varovalna tulka 4, obroč 5 z odprtino 6.
Spodnji del 1 je s pomočjo utora 2 vpet na korenu injekcijske igle. V ta namen ima koren igle izrastek v obliki obroča, ki pride v utor 2. S tem je doseženo, da je sila potrebna za snemanje ščitnika vsaj desetkrat večja od sile, ki je potrebna za raztezanje vzmeti 5. Pred uporabo igle je vzmet 3 v mirovni legi in igla štrli iz ščitnika za malo več kot je potrebna dolžina igle za vbod.
Po uporabi igle prime zdravstveni delavec ščitnik za prosti rob in ga raztegne nad konico igle. Po spustitvi roba se konica igle zatakne za notranjo površino obroča 5 in postane tako nenevarna. Varovalna tulka 4 preprečuje igli, da bi se med navoji vzmeti 3 prebila na prosto.

  1. Patentni zahtevki
    1. Injekcijska igla s ščitnikom, označena s tem, da je obdana s ščitnikom, katerega spodnji del /1/ je s pomočjo utora /2/ trdno nasajen na njen koren, da je spodnji del /1/ z vzmetjo /3/ spojen z obročem /5/, ki ima odprtino /6/ skozi katero štrli zgornji konec igle ter da je obroč /5/ trdno spojen z varovalno tulko /4/.
  2. 2. Injekcijska igla po zahtevku 1, označena s tem, da je odprtina /6/ ravno toliko velika, da tesno drsi po igli.
  3. 3· Injekcijska igla po zahtevku 1 ali 2, označena s tem, da je zunanji premer vzmeti /3/ enak štirikratnemu do petkratnemu premeru injekcijske igle.
  4. 4. Injekcijska igla po zahtevkih 1, 2 ali 3, označena s tem, da je celotna dolžina igle enaka štirikratni do petkratni dolžini ščitnika, kadar vzmet /3/ ni napeta.
