Multi-cavity multi-bag tube capable of achieving fixed-point hemostasis

Abstract

The invention discloses a multi-cavity multi-bag tube capable of achieving fixed-point hemostasis. The multi-cavity multi-bag tube is used for solving the problems that in the prior art, a three-cavity two-bag tube cannot effectively determine a bleeding point, and a hemostasis air bag is large in size and is likely to be pressed into a damaged part. The multi-cavity multi-bag tube structurally comprises a catheter, a hemostasis bag, a positioning bag and a stomach bag, wherein the hemostasis bag is arranged on the outer side of the middle of the catheter, the hemostasis bag can expand after being inflated, the bleeding position is pressed, and therefore esophagus bleeding is stopped; the hemostasis bag is composed of a plurality of hemostasis bag bodies with the small length, after the bleeding position is determined through a transnasal gastroscope, only the hemostasis bag body close to the bleeding position is used for hemostasis, the length of the hemostasis bag is small, pressingon the undamaged part is reduced, fixed-point hemostasis is achieved, and the discomfort of a patient is smaller; meanwhile, the positioning bag on the top of the hemostasis bag is fixed into the esophagus after being inflated, and the situation that the catheter moves downwards, and consequently the hemostasis bag moves is avoided; and in addition, the contact area of the conical bag and the stomach is larger, and a better use effect is achieved for fundus hemorrhage.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a multi-cavity multi-capsule tube capable of fixed-point hemostasis. Background technique [0002] For patients with esophageal and gastric fundus variceal rupture caused by cirrhosis and portal hypertension in the acute stage or patients with a large amount of bleeding and unable to maintain effective blood volume, the treatment is mainly to use three-lumen two-capsule catheter for compression hemostasis, which has a significant hemostatic effect and is the first choice The basic treatment mechanism of the three-lumen two-capsule tube is that the gastric tube has an esophageal balloon and a gastric balloon. After inflation, the soft balloon pressure is used to respectively compress the lower esophagus and the varicose veins bleeding from the gastric fundus to achieve hemostasis. Purpose: The length of the esophageal balloon of the three-chamber two-capsule tu...

[0002] For patients with esophageal and gastric fundus variceal rupture caused by cirrhosis and portal hypertension in the acute stage or patients with a large amount of bleeding and unable to maintain effective blood volume, the treatment is mainly to use three-lumen two-capsule catheter for compression hemostasis, which has a significant hemostatic effect and is the first choice The basic treatment mechanism of the three-lumen two-capsule tube is that the gastric tube has an esophageal balloon and a gastric balloon. After inflation, the soft balloon pressure is used to respectively compress the lower esophagus and the varicose veins bleeding from the gastric fundus to achieve hemostasis. Purpose: The length of the esophageal balloon of the three-chamber two-capsule tube in the prior art is longer, because the position of bleeding cannot be accurately determined during the catheterization process, so the longer esophageal balloon is filled to the approximate bleeding position, In this way, the bleeding site can be compressed, which is very effective in the first aid process, but relatively, due to the large area of ​​compression, it is necessary to release the airbag in a timely manner, and the doctor cannot know the specific healing of the bleeding site. On the other hand , long-term compression may cause local mucosal ischemia of the esophagus, leading to the occurrence of esophageal ulcers and even perforation, which may bring disastrous consequences to the patient, which is not good for the treatment process

[0003] The Chinese invention patent with application number 201320215466.4 discloses a visible three-chamber two-capsule catheter, which is improved on the basis of the prior art three-chamber two-capsule catheter. The acquisition device realizes the image acquisition through equipment such as capsule endoscopy, so the location of the bleeding can be more clearly identified. However, since the image acquisition device is located at one end of the three-chamber two-capsule tube, it cannot be observed after implantation. In addition, the insertion method of this application is different from the prior art. It is not inserted from the nasal cavity but from the oral cavity. It is to let the patient swallow the image capture device first, and then the image capture device After swallowing, the subsequent catheter enters the esophagus, but because it enters through the mouth, the air bag on the catheter can easily irritate the base of the tongue, causing a vomiting reaction, and a mouth opener is needed to assist in opening the mouth, otherwise the patient will lose weight when the jaw is closed. It is easy to bite the tube and damage the temporomandibular joint, and the three-cavity two-capsule tube will last for several days at a time, causing discomfort to the patient far more than that caused by nasal insertion; and the rest of this application is still It is still the existing technology that is still used, so it cannot solve the problem that the esophageal air tube in the prior art is too long and easily compresses the non-bleeding esophagus
