Problems solved by technology

At present, it is necessary to routinely ligate the bilateral internal iliac arteries to reduce intraoperative bleeding in clinical practice. This surgical procedure requires the patient to ligate the bilateral internal iliac arteries in the supine position, and then turn to the prone position for sacral tumor resection, requiring multiple surgical incisions. The operation time is long, resulting in greater trauma to the patient

Embodiment 1

[0016] Example 1 The structure of a blood flow blocking drainage tube is as follows:

[0017] See attached figure 1 , figure 2 and image 3 , the thin-walled sandwich balloon vascular occlusion drainage tube mainly connects the airbag 4, the inflation pipe 12 and the inflation nozzle 2 through the hollow tube 11, the front and rear sections of the airbag 4 are the front hollow tube 3 and the rear hollow tube 5, and the front and rear hollow tubes 5. The head end of the hollow tube 3 is the front pressure monitoring port 1, and the tail end of the rear hollow tube 5 is the rear pressure monitoring port 6. The interlayer airbag is actually a double-layer thin-walled airbag, and the outer airbag layer 7 and the inner airbag layer 8 form an airtight airbag interlayer 9 . The inflation pipe 12 is connected with the inflation pipe mouth 2, and is connected and communicated with the inflation mouth 13, and the airflow of the inflation pipe mouth 2 enters the airbag interlayer 9 t...

Embodiment 2

[0019] Through an example of use, explain the use method of the thin-wall dissection balloon blood vessel occlusion drainage tube of the present invention:

[0020] Use a commercially available internal jugular vein puncture kit to puncture the internal jugular or femoral vein, place a guide wire, dilate the skin and internal jugular vein with the skin expansion tube attached to the venipuncture kit, place a commercially available floating catheter overtube along the guide wire, and suture fixed. Connect the front pressure monitoring port 1 with a 20ml syringe, inject heparin saline to pre-fill the hollow tube 11, connect the inflation tube port 2 with a 10ml syringe to check the integrity of the air bag, and completely pump out the air. Then the thin-wall dissection balloon vascular blocking drainage tube of the present invention is put into the floating catheter overtube, and advanced to a suitable position (the position of the drainage and blocking tube is determined by the...

Abstract

The blood vessel blocking drainage tube with thin wall sandwiched balloon has the structure including one inflatable sandwich formed with one inner air bag and one outer air bag, and one hollow tube including one front part outside the air bags and one back pat, with the hollow tube possessing one front pressure monitoring port in the end of the front part and one back pressure monitoring port in the end of the back part. There are also one inflating pipe set inside the hollow tube and extending into the air bag, and one pipe inside the sandwich for blood to flow back. The blood vessel blocking drainage tube has both blood flow blocking and blood draining functions, and is set in proper position of artery and vein.

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 arteries and veins, and is suitable for blocking the inferior vena cava during liver surgery to reduce return Flowing bleeding, and various occasions that need to block arteries to reduce intraoperative 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 tumor...
