Bronchus blocker and artificial respiration system
View Patent ↗The bronchus blocker according to the invention comprises an insertion rod and a blocking means. The blocking means is provided near one end of the insertion rod in order to be inserted by means thereof into a bronchus. The bronchus blocker furthermore comprises a support, for supporting the bronchus blocker on a bronchial branching, such as the carina. By supporting the bronchus blocker on a bronchial branching using its support, the inflated balloon only has to seal the bronchus and does not also have to keep the bronchus blocker in its position at the same time. As a result, the risk of the bronchus blocker slipping out of its position is much smaller than with the prior art.
1. An artificial respiration system comprising:
a bronchus blocker for sealing off one bronchus of two bronchi, the bronchus blocker including an insertion rod and a blocking means, the blocking means being provided near one end of the insertion rod in order to be inserted by means thereof into the one bronchus, the bronchus blocker further including a support for supporting the bronchus blocker on a bronchial branching, the support of the bronchus blocker includes two support parts each intended for support on either side of the bronchial branching, each of the two support parts being expandable, wherein the bronchus blocker is configured to completely seal the one bronchus; and
a respiration tube, the respiration tube consisting of one tube, the respiration tube including at least one first lumen, in which the respiration tube is suitable for receiving the bronchus blocker in order to insert the bronchus blocker into a trachea, wherein the respiration tube is configured to remain within the trachea without extending into the brachial branching and provide air to the other bronchus.
2. The artificial respiration system of claim 1 , wherein the support of the bronchus blocker is fitted on the insertion rod so as to be movable, in order to occupy either a supporting position or an insertion position.
3. The artificial respiration system of claim 2 , wherein the support of the bronchus blocker is rotatable with respect to the insertion rod.
4. The artificial respiration system of claim 2 , wherein the support of the bronchus blocker can be displaced laterally with respect to the insertion rod.
5. The artificial respiration system of claim 1 , wherein each of the two expandable support parts is a balloon which is inflatable via a lumen in the insertion rod.
6. The artificial respiration system of claim 1 , wherein the two support parts may be at a support angle (β) with respect to one another.
7. The artificial respiration system according to claim 1 , further comprising a compensating device which connects the bronchus blocker and the respiration tube with one another so that they are movable in the longitudinal direction in such a manner that in use the respiration tube is movable with respect to the bronchial branching while the bronchus blocker is supported against the bronchial branching.
8. The artificial respiration system according to claim 7 , in which the compensating device comprises a spring means.
9. The artificial respiration system according to claim 1 , in which the respiration tube functions as the insertion rod.
10. The artificial respiration system according to claim 1 , in which the respiration tube is provided with an expandable sealing means around its circumference in order to connect the exterior of the tube with the trachea in an airtight manner.
11. The artificial respiration system according to claim 1 , in which the respiration tube comprises at least one second lumen.
12. A method of using a bronchus blocker according to claim 1 , comprising:
inserting the respiration tube into the trachea; and
inserting the bronchus blocker into the one bronchus, wherein the bronchus blocker seals off the one bronchus of a respiratory system.
