Abstract
Description
Korte aanduiding: Steun voor bronchusblokkeerder en beademingssysteem met een met zo’n steun uitgeruste bronchusblokkeerder en beademings-buis.Brief indication: Support for bronchus blocker and ventilation system with a bronchus blocker and ventilation tube fitted with such a support.
5 De uitvinding heeft betrekking op een bronchusblokkeersysteem voorzien van een steun die onder meer voorkomt dat door het afsteunen op de bronchussplitsing schade aan de bronchussplitsing wordt toegebracht.The invention relates to a bronchus blocking system provided with a support which inter alia prevents damage to the bronchus division from being supported by the support to the bronchial cleavage.
Een bronchusblokkeerinrichting die afsteunt op de bronchussplitsing is bekend uit het 10 Nederlandse octrooi NL 1026190. Een uitvoeringsvorm van de in dit octrooi beschreven bronchusblokkeerinrichting bestaat uit twee lumen die elk aan hun uiteinde een blokkeerelement hebben. Dit blokkeerelement is expandeerbaar, bijvoorbeeld een ballon. In geval van een ballon kan dit vanuit het lumen opgeblazen en weer leeggemaakt worden. Op enige afstand van de een blokkeerelement bevattende uiteinden 15 van de lumen, komen de twee lumen samen en dit punt van samenkomst vormt de steun die op de bronchussplitsing afsteunt.A bronchus blocking device based on the bronchus cleavage is known from Dutch patent NL 1026190. An embodiment of the bronchus blocking device described in this patent consists of two lumen, each of which has a blocking element at their end. This blocking element is expandable, for example a balloon. In the case of a balloon, this can be inflated from the lumen and emptied again. At some distance from the ends of the lumen containing a blocking element, the two lumen come together and this point of meeting forms the support that is supported by the bronchial junction.
Het nadeel van deze afsteuning op de bronchussplitsing is, dat bij langdurig met enige kracht afsteunen schade aan de bronchussplitsing toegebracht kan worden. Verder is 20 het zo dat de beide lumen bij het inbrengen van de bronchusblokkeerinrichting, zolang mogelijk en zo dicht mogelijk bij elkaar gehouden dienen te worden om schade aan de wand van de luchtpijp te voorkomen en te voorkomen dat een van de lumen in een Murphy-eye of andere opening van de endotracheale beademingsbuis blijft hangen.The disadvantage of this support for the bronchial cleavage is that damage to the bronchial cleavage can be caused with long-term support with some force. Furthermore, when introducing the bronchus blocking device, the two lumen must be kept as long as possible and as close as possible to each other in order to prevent damage to the wall of the windpipe and to prevent one of the lumen from entering a Murphy eye or other opening of the endotracheal breathing tube lingers.
Pas in de nabijheid van de bronchussplitsing dienen de lumen zo ver uit elkaar 25 gebracht te worden dat ze in de linker respectievelijk rechter bronchus ingebracht kunnen worden.Only in the vicinity of the bronchial cleavage should the lumen be moved so far apart that they can be introduced into the left and right bronchus, respectively.
Doel van de onderhavige vinding is de hiervoor genoemde problemen op te lossen. Dit wordt bereikt door de lumen bij het inbrengen bij elkaar te houden. Bij het naderen van 30 de bronchussplitsing wordt een element geëxpandeerd, dat zich bevindt op het punt van samenkomst van de lumen. Door het expanderen van dit element worden de lumen 1033898 2 uit elkaar gedrukt. Bij het verder inbrengen van de bronchusblokkeerinrichting, gaan de lumen elk in een van de twee bronchi in. Op uit het Nederlandse octrooi NL 1026190 bekende wijze, wordt vervolgens door het expanderen van het blokkeer-element, de gewenste bronchus afgesloten.The purpose of the present invention is to solve the aforementioned problems. This is achieved by holding the lumen together during insertion. As the bronchial cleavage approaches, an element is expanded at the point where the lumen meets. The lumen 1033898 2 is pressed apart by expanding this element. Upon further introduction of the bronchus blocking device, the lumen each enter one of the two bronchi. In a manner known from Dutch patent NL 1026190, the desired bronchus is subsequently closed off by expanding the blocking element.

Het in het punt van samenkomst van de lumen geëxpandeerde element dient als afsteuning van de bronchusblokkeerinrichting op de bronchussplitsing.The element expanded at the point of intersection of the lumen serves as a support for the bronchus blocker on the bronchus junction.
Een uitvoeringsvorm van de uitvinding zal aan de hand van bijgaande figuren nader 10 worden toegelicht, waarin:An embodiment of the invention will be explained in more detail with reference to the accompanying figures, in which:
Figuur 1 de bronchusblokkeerinrichting in de luchtpijp en nabij de bronchus-splitsing toont;Figure 1 shows the bronchus blocking device in the windpipe and near the bronchus junction;
Figuur 2 de bronchusblokkeerinrichting toont met geëxpandeerd element op het punt van samenkomst van de lumen; 15 Figuur 3 de bronchusblokkeerinrichting toont die ingebracht is tot het geëxpan deerde element steunt op de bronchussplitsing.Figure 2 shows the bronchus blocking device with the expanded element at the point where the lumen meets; Figure 3 shows the bronchus blocking device inserted until the expanded element is supported by the bronchus cleavage.
In een voordelige uitvoeringsvorm bestaat de bronchusblokkeerinrichting (1) uit een katheter met drie lumen (2), (3), en (4). De twee lumen (2) en (4) bevatten aan hun 20 distale eind een expandeerbaar blokkeerelement (5) en (6). De derde lumen (3) bevindt zich op, tussen of tegen de andere twee lumen (2) en (4). De twee lumen (2) en (4) met blokkeerelementen (5) en (6) lopen vanaf het zich aan het distale einde van de bronchusblokkeerinrichting (1) bevindende splitsingspunt (7) los van elkaar verder door. Op dit splitsingspunt (7) eindigt de derde lumen (3) in een expandeerbaar 25 afsteunelement (8). Dit afsteunelement (8) kan bijvoorbeeld een ballon zijn die via de derde lumen (3) opgeblazen of weer leeggezogen kan worden.In an advantageous embodiment, the bronchus blocking device (1) consists of a catheter with three lumen (2), (3), and (4). The two lumen (2) and (4) have an expandable blocking element (5) and (6) at their distal end. The third lumen (3) is on, between or against the other two lumen (2) and (4). The two lumen (2) and (4) with blocking elements (5) and (6) continue separately from the splitting point (7) located at the distal end of the bronchus blocking device (1). At this junction (7) the third lumen (3) ends in an expandable support element (8). This support element (8) can for instance be a balloon which can be inflated or sucked out again via the third lumen (3).
Het afsteunelement (8) is zodanig aangebracht en vormgegeven dat door dit afsteunelement (8) te expanderen, bijvoorbeeld door de ballon op te blazen, de voorbij het 30 splitsingspunt (7) liggende delen van de lumen (2) en (4) met blokkeerelementen (5) en (6) uit elkaar bewogen worden. De bronchusblokkeerinrichting (1) verkrijgt dan een 3 Y-vorm waarvan de benen van de Y gevormd worden door de voorbij het splitsings-punt (7) liggende delen van de lumen (2) en (4) met blokkeerelementen (5) en (6).The support element (8) is arranged and shaped such that by expanding this support element (8), for example by inflating the balloon, the parts of the lumen (2) and (4) with blocking elements lying beyond the point of splitting (7) (5) and (6) are moved apart. The bronchus blocking device (1) then acquires a 3 Y-shape, the legs of the Y of which are formed by the parts of the lumen (2) and (4) with blocking elements (5) and (6) which lie beyond the splitting point (7) ).
Bij het inbrengen van de bronchusblokkeerinrichting (1) in de luchtpijp (9) door de 5 endotracheale beademingsbuis (gestippeld in de figuren weergegeven) zijn de blokkeerelementen (5) en (6) en het afsteunelement (8) niet opgeblazen. De lumen (2) en (4) liggen daardoor strak tegen elkaar aan om bij het inbrengen van de bronchusblokkeerinrichting (1) in de luchtpijp (9) door de endotracheale beademingsbuis schade aan de wand van de luchtpijp te voorkomen en te voorkomen dat een van de 10 lumen in een Murphy-eye of andere opening van de endotracheale beademingsbuis blijft hangen. Bij het naderen van de carina of bronchussplitsing (10), wordt het afsteunelement (8) geëxpandeerd, bijvoorbeeld opgeblazen, en worden de lumen (2) en (4) uit elkaar gedrukt. De hoek die de lumen (2) en (4) met elkaar vormen is afhankelijk van de hoek tussen de bronchi; deze hoek is bijvoorbeeld ongeveer 60 15 graden. Als vervolgens de bronchusblokkeerinrichting (1) verder in de luchtpijp (9) gebracht wordt, zullen de lumen (2) en (4) elk in één bronchus ingevoerd worden. Het inbrengen van de bronchusblokkeerinrichting (1) in de luchtpijp (9) gaat door tot het afsteunelement (8) op de bronchussplitsing (10) stuit. Afhankelijk van welke bronchus afgesloten dient te worden, kan blokkeerelement (5) of (6) opgeblazen worden.When the bronchus blocking device (1) is introduced into the windpipe (9) through the endotracheal respiration tube (shown in dotted lines in the figures), the blocking elements (5) and (6) and the supporting element (8) are not inflated. The lumen (2) and (4) therefore lie tightly against each other in order to prevent damage to the wall of the trachea and prevent any of the wall of the trachea when inserting the bronchus blocking device (1) into the windpipe (9) through the endotracheal breathing tube the 10 lumen remains in a Murphy-eye or other opening of the endotracheal breathing tube. When approaching the carina or bronchial fission (10), the support element (8) is expanded, for example, inflated, and the lumen (2) and (4) are pressed apart. The angle that the lumen (2) and (4) form with each other depends on the angle between the bronchi; for example, this angle is approximately 60 to 15 degrees. Subsequently, if the bronchus blocking device (1) is introduced further into the trachea (9), the lumen (2) and (4) will each be introduced into one bronchus. The introduction of the bronchus blocking device (1) into the windpipe (9) continues until the support element (8) encounters the bronchus junction (10). Depending on which bronchus should be closed, the blocking element (5) or (6) can be inflated.

De vorm van het afsteunelement (8) is zodanig dat zijdelingse bewegingen van de afsteunende bronchusblokkeerinrichting (1) bemoeilijkt worden en onbedoeld ver doorschieten van lumen (2) of (4) in de bronchus zoveel als mogelijk is, vermeden wordt. Het afsteunelement (8) kan bijvoorbeeld als een zadel uitgevoerd worden dat 25 bij het afsteunen, op de bronchussplitsing (10) ligt. Deze “zadel”vorm kan bijvoorbeeld verkregen worden door het afsteunelement (8) in het symmetrievlak tussen de lumen (2) en (4) te voorzien van een band (8c) die niet of veel minder elastisch is dan de rest van het afsteunelement (8). Bij het expanderen of opblazen van het afsteunelement (8) zullen de delen (8a) en (8b) meer uitzetten dan de band (8c) waardoor de 30 gewenste “zadeI”vorm van het afsteunelement (8) ontstaat. De band (8c) kan een integraal onderdeel zijn van het afsteunelement (8) en kan zijn verkregen door een deel 4 van het afsteunelement (8) een speciale behandeling te geven. Een andere mogelijkheid is dat de band (8c) uitdrukkelijk geen integraal onderdeel van het afsteunelement (8) is maar hierop is aangebracht.The shape of the supporting element (8) is such that lateral movements of the supporting bronchus blocking device (1) are made more difficult and unintentional overshoot of lumen (2) or (4) in the bronchus is avoided as much as possible. The supporting element (8) can for instance be designed as a saddle which, when supported, rests on the bronchial junction (10). This "saddle" shape can be obtained, for example, by providing the support element (8) in the plane of symmetry between the lumen (2) and (4) with a band (8c) that is not or much less elastic than the rest of the support element ( 8). When expanding or inflating the support element (8), the parts (8a) and (8b) will expand more than the belt (8c), creating the desired "seed" shape of the support element (8). The belt (8c) can be an integral part of the support element (8) and can be obtained by giving part 4 of the support element (8) a special treatment. Another possibility is that the band (8c) is explicitly not an integral part of the supporting element (8) but is mounted on it.
5 De afmetingen van de bronchusblokkeerinrichting (1) zijn zo uitgevoerd dat de katheter, die de drie lumen bevat, zo weinig mogelijk ruimte in de luchtpijp (9) inneemt; de doorsnede zou bijvoorbeeld 3 mm (9 french) kunnen zijn. Een gebruikelijke lengte van de, van een maatverdeling voorziene, katheter is 70 cm. De expandeerbare blokkeerelementen (5) en (6) kunnen, afhankelijk van wat wenselijk is, 10 uitgevoerd zijn als ballonnen met een diameter van 2,5 tot 3,0 cm en met een lengte van 1,5 tot 2,0 cm. Belangrijk is dat het blokkeerelement dat niet geëxpandeerd wordt, zo weinig mogelijk ruimte in de bronchus inneemt om de beademing van die long zou weinig mogelijk te hinderen.The dimensions of the bronchus blocking device (1) are designed in such a way that the catheter, which contains the three lumen, occupies as little space as possible in the windpipe (9); the cross-section could, for example, be 3 mm (9 french). A typical length of the catheter provided with a graduation is 70 cm. The expandable blocking elements (5) and (6) can, depending on what is desired, be designed as balloons with a diameter of 2.5 to 3.0 cm and with a length of 1.5 to 2.0 cm. It is important that the blocking element that is not expanded takes up as little space as possible in the bronchus to hinder the ventilation of that lung as little as possible.
