Description
7M1i 85-13 10 15 20 25 30 35 z »- 4- - fattande ett skaft uppbärande en uppblåsbar hylsa, som vid sina ändarär förenad med ytterytan av skaftet, kännetecknad därav, att den uppvisar ett flertal inre pâ avstånd, längs Omkretsen anord- nade spår i ett parti av hylsan mellan de med skaftet förenade ändarna, vilka.spår separeras genom upphöjningar som står i kon- takt med skaftet när hylsan ej är uppblåst. 7M1i 85-13 10 15 20 25 30 35 z »- 4- - comprising a shaft carrying an inflatable sleeve, which at its ends is connected to the outer surface of the shaft, characterized in that it has a plurality of interiors at a distance, along the circumference arranged grooves in a portion of the sleeve between the ends joined to the shaft, which grooves are separated by elevations which are in contact with the shaft when the sleeve is not inflated.
Vissa utföringsformer av uppfinningen beskrivs närmare i det följande med hänvisning till de bifogade ritningarna, varpå fig¿_l visar en vy i höjdled av en första utföringsform av en kateter enligt uppfinningen; och fig. Z visar en fragmentarísk tvärsnittsvy av en annan utföringsform.Certain embodiments of the invention are described in more detail below with reference to the accompanying drawings, in which: Fig. 1 shows a elevational view of a first embodiment of a catheter according to the invention; and Fig. Z shows a fragmentary cross-sectional view of another embodiment.
I figuerna betecknar samma hänvisningsbeteckningar lika- dana delar.In the figures, the same reference numerals denote like parts.
Katetern 10 som visas i fig. 1 innefattar ett skaft 12 och en uppblåsbar ballong som utgöres av en ringformig hylsa 14 av elastiskt material som omger skaftet. Skaftet 12 och hylsan 14 kan utgöras av vilket som helst lämpligt material, såsom silikon- eller latexgummi.The catheter 10 shown in Fig. 1 includes a shaft 12 and an inflatable balloon formed by an annular sleeve 14 of elastic material surrounding the shaft. The shaft 12 and the sleeve 14 may be of any suitable material, such as silicone or latex rubber.
Såsom framgår av figuren uppvisar skaftet 12 åtminstone en dräneringsöppning 16 intill den dístala änden 18 av skaftet 12 och en dräneringskanal 20 som utsträcker sig genom skaftet.As shown in the figure, the shaft 12 has at least one drainage opening 16 adjacent the distal end 18 of the shaft 12 and a drainage channel 20 extending through the shaft.
Katetern uppvisar en anslutning 22 i den proximala änden 24 som under användning av katetern anslutes till ett dräneringsrör (ej visat). Katetern uppvisar också en sidoarm 26 uppvisande en konventionell ventil (ej visad) för användning vid uppblâsning av hylsan 14. En uppblåsningskanal 28 utsträcker sig genom väggen av skaftet 12 och tillhandahåller förbindelse mellan sido- armen 26 och en hålighet 30 mellan hylsan 14 och skaftet 12.The catheter has a connection 22 at the proximal end 24 which during use of the catheter is connected to a drainage tube (not shown). The catheter also has a side arm 26 having a conventional valve (not shown) for use in inflating the sleeve 14. An inflation channel 28 extends through the wall of the shaft 12 and provides communication between the side arm 26 and a cavity 30 between the sleeve 14 and the shaft 12. .
Uppblåsningskanalen 28 står i förbindelse med håligheten 30 genom en öppning 32 i väggen av skaftet 12 så att ett fluidum kan pumpas genom sidoarmen 26, uppblåsningskanalen 28 och öppningen 32 in i håligheten 30 för uppblåsning av hylsan 14.The inflation channel 28 communicates with the cavity 30 through an opening 32 in the wall of the shaft 12 so that a fluid can be pumped through the side arm 26, the inflation channel 28 and the opening 32 into the cavity 30 to inflate the sleeve 14.
Hylsan 14 är ansluten till skaftet 12 vid på avstånd be- lägna zoner 34 och 36 i omkretsen, som tillsluter ändarna av håligheten 30. Hylsan 14 kan vara förenad med skaftet 12 vid gdessa zoner genom vilken som helst lämplig bindníngsanordning, såsom ett bindemedel eller genom varmförsegling. Hylsan 14 uppvisar en innerytu 38 vänd mot den yttre ytan 40 av skaftet 12. 10 15 78111854» Såsom framgår av fig. 2 definieras ytor 46 av spår 50 i omkretsen 1 ínnerväggen av hylsan 14. Spåren 50 Separeras genom upphöjningar 52 i omkretsen, som separerar ytorna 46 i områden 48 definierade genom upphöjningarna 52. Upphöjningarna 52 de- finierar ett flertal områden 48 mellan ytorna 46 vid vilka hylsan 14 kan komma i kontakt med skaftet 12 så att hylsan stödjes.The sleeve 14 is connected to the shaft 12 at spaced zones 34 and 36 in the circumference which close the ends of the cavity 30. The sleeve 14 may be connected to the shaft 12 at these zones by any suitable bonding device, such as an adhesive or by heat seal. The sleeve 14 has an inner surface 38 facing the outer surface 40 of the shaft 12. As shown in Fig. 2, surfaces 46 are defined by grooves 50 in the circumference 1 of the inner wall of the sleeve 14. The grooves 50 are separated by elevations 52 in the circumference, which separates the surfaces 46 into areas 48 defined by the elevations 52. The elevations 52 define a plurality of areas 48 between the surfaces 46 at which the sleeve 14 can come into contact with the shaft 12 so that the sleeve is supported.
Hylsan 14 hindras från att komma i kontakt med skaftet 12 vid ytorna 46 varigenom den totala kontaktytan mellan hylsan och skaftet reduceras. Detta minimerar möjligheten för hylsan 14 att häfta vid skaftet 12 vid användningstíllfället på grund av arten av materialen varav hylsan och skaftet är framställda, speciellt för fallet silikon- eller latexgummí~ katetrar, varigenom uppblåsning av ballongen skulle kunna för- hindras eller distortíon av ballongen när denna uppblåses skulle kunna framkallas såsom förklarats tidigare.The sleeve 14 is prevented from coming into contact with the shaft 12 at the surfaces 46, whereby the total contact surface between the sleeve and the shaft is reduced. This minimizes the possibility of the sleeve 14 adhering to the shaft 12 at the time of use due to the nature of the materials from which the sleeve and shaft are made, especially in the case of silicone or latex rubber catheters, thereby preventing inflation of the balloon or distortion of the balloon when this swelling could be induced as explained earlier.
