Description
Technical Field
[0001] The utility model belongs to the technical field of medical appliances, and in particular relates to a three-cavity two-balloon tube traction stent. Background Art
[0002] In the treatment of diseases such as esophageal varicose vein rupture and bleeding caused by liver cirrhosis, medical staff need to insert a three-chamber two-balloon tube into the patient's esophagus and stomach, and use the balloon to inflate to compress and stop bleeding, while the traction stent plays the role of fixing and maintaining the position and traction strength of the three-chamber two-balloon tube. Through this appropriate traction tension, the balloon can be more tightly attached to the bleeding site, enhancing the effect of compression and hemostasis. When traction is applied to the three-chamber two-balloon tube, in order to ensure the uniformity and durability of the traction force, traction is generally applied to the three-chamber two-balloon tube by weights. In actual use, since there is no fixed standard for the quality of the weights used, the principle is to achieve effective hemostasis and the patient can tolerate it. Therefore, in the selection of weights, medical staff generally need to make judgments based on experience. When the medical staff's judgment is biased, resulting in the patient being unable to tolerate and needing to replace weights of different weights, the medical staff needs to remove the weights. At this time, the weights will cancel the traction of the three-chamber two-balloon tube, resulting in the three-chamber two-balloon tube being unable to be fixed due to lack of traction, and there is a risk of easy displacement.
