Abstract

1. A disposable catheter having an X-ray contrast strip (2, 3) arranged spiral-like in the longitudinal direction of the catheter, characterized by two or more X-ray contrast strips (2, 3) arranged spiral-like and in staggered form in the longitudinal direction of the catheter which strips, when X-rayed appear in the projection as a chain of points of intersection (1) successively arranged in axial direction of the catheter.

Description

Foreliggende oppfinnelse angår et kateter for engangsbruk med i kateterets lengderetning skruelinjeformet anordnede røntgenkontrastbånd. The present invention relates to a catheter for single use with X-ray contrast bands arranged helically in the longitudinal direction of the catheter.

Et kjent kateter, US PS 3 070 132 er utstyrt med et bånd A known catheter, US PS 3 070 132 is equipped with a band

som er ugjennomtrengelig for røntgenstråler og dette båndet forløper rett i kateterets lengderetning. Et slikt rett røntgenkontrastbånd er smalt og kan på røntgenskjermen ikke klart kjennes igjen fordi det parallelt med det i venen fremskjøvne kateter også kan forløpe kar, strenger og organer som på grunn av sin høye tetthet også kan bli siktbare på røntgenskjermen slik at kateteret ikke fremhever seg merk-bart omgivelsene. Erkjennelsen blir ennu mer utydelig når røntgenkontrastbåndet i forhold til røntgenskjermen befinner seg på baksiden av kateteret. Videre er det for dette kateter ikke mulig å bestemme den innlagte lengde. which is impervious to X-rays and this band runs straight along the length of the catheter. Such a straight X-ray contrast band is narrow and cannot be clearly recognized on the X-ray screen because vessels, strings and organs can also run parallel to the catheter advanced in the vein which, due to their high density, can also become visible on the X-ray screen so that the catheter does not stand out notice the surroundings. The recognition becomes even more indistinct when the X-ray contrast band in relation to the X-ray screen is located on the back of the catheter. Furthermore, for this catheter it is not possible to determine the inserted length.

Videre er det fra US PS 3 070 132 og US PS 3 410 6506 kjent Furthermore, it is known from US PS 3 070 132 and US PS 3 410 6506

å utstyre et kateter med et enkelt skruelinjeformet røntgen-kontrastbånd. Ett eneste skruelinjeformig røntgenkontrast-bånd fremhever seg imidlertid like lite røntgenologisk fra de synlige organer som et rett røntgenkontrastbånd slik at også dette er vanskelig å erkjenne. Videre mangler også her holdepunkter for innlagt kateterlengde. to equip a catheter with a single helical x-ray contrast band. However, a single helical X-ray contrast band stands out as little radiologically from the visible organs as a straight X-ray contrast band, so that this too is difficult to recognize. Furthermore, there is also a lack of reference points for the length of the inserted catheter.

Foreliggende oppfinnelse har til oppgave å utstyre et kateter med røntgenkontrastbånd på en slik måte at lengden uav-hengig av andre røntgenologisk viste organer differensiert og pålitelig kan erkjennes på røntgenskjermen og slik at derved også den innlagte lengde av kateteret uten vanskelig-het kan bedømmes. The present invention has the task of equipping a catheter with an X-ray contrast band in such a way that the length can be differentiated and reliably recognized on the X-ray screen, independently of other X-ray visible organs, and so that thereby also the length of the inserted catheter can be assessed without difficulty.

Denne oppgave løses ved å utstyre kateteret med to eller flere i kateterets lengderetning skrulinjeformig og forskutt anordnede røntgenkontrastbånd som i projesjon ved røntgenopp-tak gir en i aksial retning av kateteret forløpende sammen-hengende kjede av krysningspunkter, fortrinnsvis slik at stigningen og antallet av røntgenkontrastbåndene gir en isometrisk oppdeling av de projeserte krysningspunkter. This task is solved by equipping the catheter with two or more x-ray contrast bands arranged helically and staggered in the lengthwise direction of the catheter, which in projection during x-ray recording give a continuous chain of crossing points in the axial direction of the catheter, preferably so that the pitch and number of the x-ray contrast bands give an isometric breakdown of the projected intersection points.

Et slikt for engangsanvendelse og spesielt som venekateter mente kateter lar seg tydelig forfølge på røntgenskjermen på grunn av den i enhver stilling for kateteret nøyaktig gjenkjennbare kjede av krysningspunkter fordi krysnings-punktene ikke kan forveksles med røntgenologisk likeledes viste organer, slik at her er mulig med en differensiert bedømmelse av kateterpossisjonen. Gjengivelsen i prosjek-sjon av de skruelinjeformede røntgenkontrastbånd som krysser hverandre forbedres pa grunn av den dobbelte materialtykkelse i røntgenkontrastbåndene i krysningspunktet. Krysningspunktet gir seg hver gang på grunn av de i det projeserte plan på tvers av hverandre forløpende røntgen-kontrastbånd hvis antall pr. lengderettiaksial kateter-retning bestemmes av avstanden mellom kontrastbåndene seg i mellom og stigningen. De på denne måte oppnådde røntgenolog-isk erkjennbare oppdeling av katetere kan være et mål for innlagt lengde av kateteret og gir et mål for orientering av kateterets possisjon og stilling. Such a one-time use, and especially as venous catheters meant catheter can be clearly followed on the X-ray screen due to the precisely recognizable chain of crossing points in any position for the catheter because the crossing points cannot be confused with organs that are also shown radiologically, so that here it is possible with a differentiated assessment of the catheter position. The reproduction in projection of the helical X-ray contrast bands that cross each other is improved due to the double material thickness in the X-ray contrast bands at the point of intersection. The crossing point occurs each time due to the x-ray contrast bands running across each other in the projected plane, the number of which per longitudinal rectiaxial catheter direction is determined by the distance between the contrast bands and the pitch. The roentgenologically recognizable division of catheters obtained in this way can be a measure of the inserted length of the catheter and provides a measure of orientation of the catheter's position and position.

Avstanden mellom minst to røntgenkontrastbånd kan være regel-messig eller uregelmessig. Stigningen og antallet av røntgen-kontrastbåndet kan gi en metrisk oppdeling de projeserte krysningspunkter. The distance between at least two X-ray contrast bands can be regular or irregular. The pitch and number of the X-ray contrast band can provide a metric division of the projected crossing points.

Tverrsnittet for røntgenkontrastbåndet i kateterveggen kan oppvise en hvilken som helst størrelse og form. Det er kun vesentlig at kateteret i røntgenkontrastbånd oppviser en homogen og i seg selv lukket, glatt totaloverflate hvorigjennom en trombedannelse unngåes. The cross-section of the X-ray contrast band in the catheter wall can be of any size and shape. It is only essential that the catheter in the X-ray contrast band exhibits a homogeneous and inherently closed, smooth overall surface, through which a thrombus formation is avoided.

Kateteret lages fortrinnsvis av et transparent materiale. The catheter is preferably made of a transparent material.

Røntgenkontrastbåndet består av et for røntgenstråleugjenn-omtrengelig materiale. The X-ray contrast tape consists of an X-ray impermeable material.

Oppfinnelsen skal beskrives nærmere under henvisning til tegningen. The invention shall be described in more detail with reference to the drawing.

Der angir: It states:

- fig. 1 et riss av et kateter med to parallelt forløpende røntgenkontrastbånd i det projeserte plan, og - fig. 2 et snitt gjennom kateteret ifølge fig. 1 langs linjen AA. - fig. 1 a view of a catheter with two parallel x-ray contrast bands in the projected plane, and - fig. 2 a section through the catheter according to fig. 1 along the line AA.

På grunn av den skruelinjeformede og forskutte anordning Due to the helical and staggered arrangement

av to_ røntgenkontrastbånd 2 og 3 krysser de på baksiden av kateteret foreliggende avsnitt 4 og 5 i projeksjonen de på forsiden motsatt løpende avsnitt for det andre røntgenkon-trastbånd 2 henholdsvis 3 og det oppstår krysningspunkter 1 som gjentar seg i regelmessige avstander. Kateterslangen består av transparent materiale slik at materialet som strømmer gjennom det kan sees i de utvendige liggende deler av kateteret. of two x-ray contrast bands 2 and 3, the sections 4 and 5 present on the back of the catheter cross in the projection the opposite running sections of the other x-ray contrast band 2 and 3 on the front, respectively, and intersection points 1 occur which repeat at regular intervals. The catheter tube consists of transparent material so that the material that flows through it can be seen in the external lying parts of the catheter.

Det i fig. 2 viste tverrsnitt forløper gjennom det i fig. 1 viste projeserte krysningspunkt 1 og man erkjenner den dobbelte materialtykkelse som oppnås i projeksjon ved krys-ning av avsnittene av kontrastbåndene 2 henholdsvis 3 på forsiden av kateteret med avsnittene 4 henholdsvis 5 på baksiden av kateteret. That in fig. 2 shown cross-section extends through that in fig. 1 showed projected crossing point 1 and one recognizes the double material thickness that is achieved in projection by crossing the sections of the contrast bands 2 and 3 respectively on the front of the catheter with the sections 4 and 5 respectively on the back of the catheter.

Røntgenkontrastbåndene 2 og 3 er innleiret i materiale i veggen 6 slik at kateteret oppviser en i seg selv sluttet og homogen og glatt totaloverflate 8. The X-ray contrast bands 2 and 3 are embedded in material in the wall 6 so that the catheter exhibits an inherently closed and homogeneous and smooth overall surface 8.
