Sengstaken-Blakemore tube traction fixation device

Abstract

The invention discloses a Sengstaken-Blakemore tube traction fixation device. The device includes a fixing base, a supporting base and a traction force adjusting mechanism, wherein the fixing base isused for fixing human body parts, the bottom of the supporting base is connected to the fixing base, one end of the traction force adjusting mechanism is connected to the supporting base, the other end of the traction force adjusting mechanism is used for being connected to a Sengstaken-Blakemore tube, and the traction force adjusting mechanism is used for adjusting a traction force performed on the Sengstaken-Blakemore tube. According to the fixation device, by fixing a layer board with a human head and fixing the traction force adjusting mechanism to the supporting base, a user can use the Sengstaken-Blakemore tube at different postures (such as a sitting posture or a lying posture), the movement of the user is not limited, and the user experience is improved.

Description

technical field [0001] The invention relates to a medical auxiliary device, in particular to a traction and fixation device with three chambers and two capsules. Background technique [0002] Three-lumen two-capsule catheter is an effective method to rescue massive hemorrhage from ruptured esophageal and gastric varices in portal hypertension. Its structure is as follows: two sacs refer to two air sacs at the front end, one circular gastric air sac compresses the fundus of the stomach after inflating; the other cylindrical esophageal air sac compresses the lower esophagus after inflating; Lumen, one is the gastric balloon, from which gas can be injected into the gastric balloon, and the gastric varices can be fully compressed after the gastric balloon is pressurized, and the pressure of the gastric bag is generally required to be 40-60mmHg; the other is the esophageal balloon, from which the esophagus can be injected Inject air into the balloon, and the esophageal balloon c...

Problems solved by technology

[0003] In the past, this tube was clinically pulled by a heavy object connected to a pulley. The patient continued to wear the tube for 24-72 hours. The patient's head was fixed and the position could not be changed. The nose at the traction site was damaged due to pressure and friction. The traction force was strong and the time was long. Most patients will experience discomfort such as chest tightness, suffocation, chest pain, etc. These not only bring great pain and inconvenience to the patients, but also once turning over or moving the head will affect the traction direction and pulling force, resulting in changes in the pressure of the esophageal pouch and gastric pouch, affect the hemostasis

[0004] Although some traction and fixation devices with three-chamber and two-capsule tubes have appeared on the market, most of them still need to restrict the patient's activities. The fixator affects the patient's breathing and speaking, and like other local fixation devices, it cannot monitor whether the pulling force is sufficient to ensure the hemostasis effect
