Description

PATENTKRAV 1. Endoskopisk sprøjteindretning med et væsketilførselsrør (2) forbundet med den bageste ende af en spiralformet rende (12) forseglet på både de indre og ydre overflader, idet en væske sendt gennem væsketilførselsrøret (2) til den spiralformede rende (12) og udsendt fra dens forreste ende hvirvles omkring den langsgående akse gennem centret af den spiralformede rende (12) inden i et væskehvirvelkammer (20) udformet foran den spiralformede rende (12), således at den udsprøjtes fra et udløb (17) dannet i centrum af den forreste endeflade af væskehvirvelkammeret (20) , kendetegnet ved, at væskehvirvelkammeret (20) er udformet som et hulrum afgrænset af en cirkulær kegleoverflade, som er konveks i retning mod udløbet (17) . 2. Endoskopisk sprøjteindretning ifølge krav l, kendetegnet ved, at udløbet (17) er placeret i forlængelse af rummet afgrænset af den cirkulære kegleoverflade indenfor en del af væskehvirvelkammeret (20) som omfatter den langsgående akse gennem centrum af den spiralformede rende (12). 3. Endoskopisk sprøjteindretning ifølge krav 1, kendetegnet ved, at et fremspring (24) ind i centrum af udløbet (17) er udformet til at stikke frem fra væskehvirvelkammeret (20). 4. Endoskopisk sprøjteindretning ifølge krav 2, kendetegnet ved, at et fremspring (24) ind i centrum af udløbet (17) er udformet til at stikke frem fra væskehvirvelkammeret (20) . 5. Endoskopiske sprøjteindretning omfattende: et væsketilførselsrør (2); en dyseelementdel (11); en distal endeafdækning (16), som huser dyseelement-delen (11) deri og støtter dyseelementdelen (11) til væsketilførselsrøret (2), idet den distale endeafdækning (2) har en udløb (17), hvor dyseelementdelen (11) og den distale endeafdækning (16) kooperativt afgrænser et væskekammer forbundet med udløbet (17), og mindst en spiralformet rende (12), som forbinder et indre af væsketilførselsrøret (2) med væskekammeret, kendetegnet ved, at væskekammeret er afgrænset af en konisk overflade af den distale endeafdækning (16) og en konisk overflade af dyseelementdelen (11) overfor den koniske overflade af den distale endeafdækning (16).
