Embodiment Construction

[0031] figure 1 A thoracentesis catheter 3 according to the invention is shown having a suction pump arrangement 10 connected to the catheter 3 by a bypass hose 9 separate from the bypass connector 8 of the catheter 3 . The catheter 3 mainly consists of a catheter shaft 2 and a catheter tip 1, wherein a check valve 7 is connected to the catheter tip and allows insertion of a needle into the catheter when the check valve 7 is in the open position and closed when the check valve 7 is in the closed position Catheter tip. At the distal end 4 of the catheter 3 is provided a through valve 6 as a needle inlet 5, which is attached image 3 is shown in more detail in the sectional view. image 3 The end of the Veress needle 18 is shown just being pushed into the needle inlet 5 . This seals the needle through valve 6 on its circumference. When the needle is fully inserted into the catheter 3 , the catheter shaft 2 can be pushed in a similar manner into the body cavity, in particular...

Abstract

The invention relates to a medical device that is in the form of a catheter (3) for supplying fluid to but in particular removing fluid from body cavities. The catheter head (1) on the proximal end (4) comprises an inlet (5) that is provided with one or more sealing and / or blocking elements (6, 7) and that is used to introduce a hollow or Verres needle (18) into the catheter (3). In the region between the sealing or blocking element(s) and the region of the catheter shaft (2) that is introduced into the body, a branch connection (8) is arranged, said branch connection being connected to a suction pump arrangement (10) via a branch tube (9). Said branch tube (9) leads to a suction valve (11) that enables a fluid to flow in the direction of the suction device, but blocks the flow in the counter direction. The outlet of the suction valve (11) opens into a forked area (12), from which one branch (16) leads to a suction device connection, in particular an injection connection (13) that is embodied, preferably, as a Luer-lock, and the other branch thereof (17) leads to a secretion bag connection (14). A non-return valve (15) that blocks the return flow of the secretion bag is arranged between said branch (17) and the secretion bag connection (14).

Description

technical field [0001] The present invention relates to a medical device in the form of a catheter for supplying fluid to and / or removing fluid from a body cavity, especially the pleural cavity, the device having a catheter tip and a catheter shaft, wherein the catheter The head has an inlet at the proximal end with one or more sealing and / or shut-off valves for inserting a hollow needle or a Verres needle into the catheter, wherein the sealing and / or shut-off valve and the catheter shaft portion The space between is designed to be inserted into the body. There is also a bypass connection, preferably via a bypass hose, to the suction pump arrangement. [0002] The device according to the invention can be used to remove air or bodily fluids by puncture from the body, however it can also find application in the veterinary field in the same way, the present invention specifically discusses applications in human medicine, preferably in the thoracic cavity Treatment of pathologic...
