specific Embodiment approach 1

[0037] An inflatable visualized gastric tube traction device according to this embodiment, such as Figure 1-3 As shown, the inflatable visualized gastric tube traction device includes an endoscope 1, a combined guiding air bag 2, an air bag band 3, a sealing plug 4, a cannula 5, a gastrointestinal tube 6 and a set of inflatable tubes 7. Mirror 1, combined guide air bag 2, sealing plug 4, sleeve tube 5, and gastrointestinal tube 6 are arranged concentrically;

[0038] The airbag belt 3 is arranged according to the extension direction of the traction device and is set on the outer wall of the combined guide airbag 2. The shape of the combined guide airbag 2 is cylindrical, and the rear end of the combined guide airbag 2 is fixedly connected to one end of the sealing plug 4. , the other end of the sealing plug 4 fits the front end of the sleeve 5, and the outer wall of the sleeve 5 fits the gastrointestinal tube 6; the endoscope 1 passes through the gastrointestinal tube 6, the ...

specific Embodiment approach 2

[0040] The difference from Embodiment 1 is that an inflatable visualized gastric tube traction device in this embodiment, such as Figure 4 As shown, the middle part of the sealing plug 4 is provided with a sealing plug middle hole 4a, so that the endoscope 1 passes through and is installed through the sealing plug middle hole 4a; the outer ring of the sealing plug middle hole 4a is evenly distributed A set of sealed lockperipheral holes 4b, so that the inflation tube 7 can pass and be installed therethrough.

[0041] There are 3-6 sealed lock holes 4b.

specific Embodiment approach 3

[0043] The difference from Embodiment 1 or Embodiment 2 is that an inflatable visualized gastric tube traction device in this embodiment, such as Figure 5 , 6 As shown, the combined guide airbag 2 includes a group of airbag modules 2a, and a group of airbag modules 2a are arranged in a circle with the central axis of the endoscope 1 as the central axis. The central axes are parallel, and each airbag module 2a is a strip-shaped hollow structure. The end of the airbag module 2a is provided with an inflation hole 2a2, and the outer wall of the airbag module 2a is arranged with a set of belt grooves 2a1 at equal intervals along the length direction. An inner groove 2a3 is provided on the inner side wall of the module 2a, and the extension direction of the inner groove 2a3 is consistent with the length direction of the airbag module 2a;

[0044] The belt groove 2a1 is used to install and fix the airbag belt 3, and the combined guide airbag 2 is fixed by means of the airbag belt 3...

Abstract

The invention discloses an inflatable visual stomach tube traction device, and belongs to the field of medical instruments. Generally, for a non-surgical patient, bare-handed application of the gastrointestinal tube can only reach the stomach, the gastrointestinal tube is difficult to enter the small intestine through pylorus, and the gastrointestinal tube easily gets stuck when touching the bottom gastric varus area. The inflatable visual stomach tube traction device is characterized in that an air bag strap (3) is sleeved outside a combined guide air bag (2), the combined guide air bag (2) is fixedly connected with a sealing plug (4), the other end of the sealing plug (4) is sleeved with a sleeve (5), and the outer wall of the sleeve (5) is sleeved with a stomach tube (6); an endoscope (1) sequentially penetrates through the stomach tube (6), the sleeve (5), the sealing plug (4) and the combined guide air bag (2), and a camera is installed at the front end of the endoscope (1); and agroup of inflating pipes (7) are uniformly arranged at the periphery of the endoscope (1). The stomach tube traction device can bend and rotate, the degree of freedom is more flexible, and bending, twisting, rotating and other operations can be achieved through the control quantity of gas in different channels.

Description

technical field [0001] The invention relates to an inflatable visual gastric tube traction device. Background technique [0002] Nasogastric (bowel) intubation is a medical procedure that involves inserting a plastic tube through a nasogastric (nasogastric) tube, or nasogastric tube, down the throat and down into the stomach (bowel). The nasogastric (bowel) tube is used for feeding and medication As well as other oral drugs, the nasogastric (intestinal) tube enters the gastric body (intestine) through the nasal cavity and esophagus through the cardia. Usually, in non-operative patients, the gastrointestinal tube can only reach the gastric body by hand, and it is difficult to enter the small intestine through the pylorus. The reason is that the gastrointestinal When the tube touches the bottom of the stomach, it is easy to get stuck in the greater curvature of the stomach. Continuous application will cause the tube to accumulate and make it difficult to move forward. The pylo...
