AI Technical Summary

Technical Problem

Existing gastrointestinal stoma tubes can easily cause a foreign body sensation and discomfort during human activity, and can easily accumulate medications or food residue, leading to bacterial growth and infection risks. The external fixation device is inconvenient to install and cannot provide effective buffering space for deformation.

Method used

A gastrostomy with a contraction zone was designed, including a tube, an internal fixation section, and an external fixation section. The internal fixation section has an inclined extension zone and a contraction zone, providing deformation space and a buffering effect. The external fixation section increases structural strength and comfort through pads and the contraction zone. The inner tube forms a straight-through tube to improve the feeding speed.

Benefits of technology

It improves user comfort, reduces foreign body sensation and infection risk, enhances the stability and ease of installation of the stoma tube, ensures that medicines or food do not accumulate, and allows for rapid feeding.

Abstract

The present application provides a kind of digestive tract fistula with collapse area, including a tube part, a internal fixation part and an external fixation part.The tube part extends along the axial direction and includes an outer tube and an inner tube, the outer tube has a first end and a second end, the inner tube extends into the outer tube and has an extended end extending out of the second end, and the inner tube can be telescopic relative to the outer tube.The internal fixation part is hollow inside and one end is fixed to the extended end of the inner tube, the other end is fixed to the outer tube, the internal fixation part extends obliquely from the one end to the radial outside to form an oblique extension area, and from the oblique extension area to the radial inside to the other end to form a first collapse area, there is at least a first notch on the oblique extension area, and there is at least a second notch on the first collapse area, the first notch is connected to the second notch.When the stoma is installed on the human body, it is less likely to cause foreign body sensation, and the comfort is better.
