Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings. Those skilled in the art should understand that the embodiments described below are only illustrative illustrations of the present invention, and are not intended to limit it in any way. For example, although the present invention has been described by applying pressure to the gastric fundus of the alimentary canal to stop bleeding, it is obvious that it can also be applied to other suitable sites or occasions for applying pressure.

[0028] Such as figure 2 In the specific embodiment shown, the device for exerting pressure inside a medical body cavity of the present invention includes a cylindrical support 3 , an openable and closable umbrella 5 and a connecting transition part 4 between them.

[0029] The cylindrical stent 3 has a generally cylindrical outer profile, is formed with a hollow channel and is radially expandable. The cylindrical bracket 3 is preferably ...

Abstract

A medical intra-cavity pressure apparatus comprises an openable-closable pressure umbrella; the pressure umbrella comprises: a plurality of main ribs; an umbrella film attached to the main ribs; a fixing rod; a plurality of first branch ribs; and a plurality of second branch ribs. The proximal end of each second branch rib is connected to the second end of the fixing rod. The medical intra-cavity pressure apparatus enables stomach fundus compression area to be significantly increased, can provide low-pressure intermittent compression, and can ensure esophageal and fundal compressed mucosae's own blood supplies to avoid necrosis of the mucosae; after being implanted, the apparatus may be subjected to gastroscopy through hollow passages of the esophageal stent and stomach fundus umbrella, and diagnosis and treatment are made possible for the hemostasis of bleeding points under a gastroscope, except for hemostatic and compressed parts; the apparatus is convenient to place and remove; the apparatus can provide preventive therapy of bleeding for a patient with long-term compression therapy or severe esophageal varices, and is suitable for treating more indications.

Description

technical field [0001] The invention relates to a pressure-applying or hemostasis device for a human body cavity, especially near the gastric fundus of the digestive tract. Background technique [0002] About 1.2 million people die from liver cirrhosis every year in the world, and it is increasing year by year. Most of the causes are rupture and bleeding of esophageal and gastric varices caused by liver cirrhosis. Commonly used hemostasis methods are drugs, instruments, interventional surgery, and laparotomy. For the acute treatment of acute severe bleeding, the current international preferred method is still the three-cavity two-capsule tube, also known as Sengstaken-Blakemore tubes or Minnesota tubes for hemostasis by compression, and a few doctors use the Linton-Nachlas tube (only one gastric balloon of about 500ml) , no esophageal air sac) compression to stop bleeding. For a long time, although the above-mentioned hemostatic devices have played an important role in the ...
