Embodiment 1

[0013] Embodiment 1 The structure of a blood flow blocking and drainage tube is as follows:

[0014] See attached figure 1 and figure 2 , the dissection airbag inferior vena cava occlusion and drainage tube is mainly connected to the airbag and the inflatable tube 1 through the hollow tube 10, the front and rear sections of the airbag are the front hollow tube 3 and the rear hollow tube 5, and the head end of the front hollow tube 3 It is the front pressure monitoring port 2, and the tail end of the rear hollow pipe 5 is the rear pressure monitoring port 6. The interlayer airbag is actually a double-layer thin-walled airbag. The outer airbag layer 7 and the inner airbag layer 8 form a closed airbag interlayer 4. The inflation pipe 11 is connected to the inflation nozzle 1 and is connected to the multi-layer support structure 13 composed of two sheets. In communication with, the airflow of the inflation nozzle 1 enters the airbag interlayer 4 through the gap between the infl...

Embodiment 2

[0016] Through an example of use, explain the use method of the internal support dissection balloon venous occlusion drainage tube of the present invention:

[0017] A commercially available jugular vein puncture kit was used to puncture the internal jugular vein until the guide wire was placed, the skin and internal jugular vein were dilated with the skin expansion tube attached to the venipuncture kit, a commercially available floating catheter overtube was placed along the guide wire, and sutures were fixed. Connect the front pressure monitoring port 2 with a 20ml syringe, inject heparin saline to pre-fill the hollow tube 10, connect the inflation tube port 1 with a 10ml syringe to check the integrity of the air bag, and completely pump out the air. Then the internal support type dissection balloon venous blocking drainage tube of the present invention is put into the floating catheter overtube, and advanced to a suitable position (the drainage and blocking tube are determin...

Abstract

The invention discloses an internal-support sandwich gas-bag venous blocking-up drain, which comprises the following parts: aerating sandwich 4 with internal gas-bag layer 8 and external gas-bag layer 7, wherein the internal part of internal gas bag is divided into three sector space by support piece 9, 12 and composite support piece 13, the hollow pipe pierces the internal and external layers of gas bag, whose external part is front hollow pipe 3 and back hollow pipe 5, the bottom of front hollow pipe contains front pressure monitoring hole 2 and the bottom of back hollow pipe possesses pressure monitoring hole 6, one aerating pipe 11 is set between two composite support pieces 13, which pierces monitoring hole 2 to aerating pipe 1.

Description

technical field [0001] The invention belongs to the technical field of clinical medicine and relates to a medical device, specifically a blood flow blocking and drainage tube, which is mainly used for blocking the blood flow of the inferior vena cava, and is suitable for blocking the inferior vena cava during liver surgery to reduce the risk of liver failure. Various occasions of reflux bleeding. Background technique [0002] In clinical work, in order to reduce the bleeding during liver surgery, it is often necessary to block the blood flow into and out of the liver at the same time. Blocking the blood flow can make the surgical field clear, so that the resection of some tumors and the repair of trauma can be carried out smoothly, especially in liver surgery, there is a lot of bleeding, and the operation cannot be performed if the blood flow into the liver is not effectively controlled; for huge right liver tumors, Caudal lobe tumors or "central" liver cancer adjacent to t...
