Embodiment Construction

[0031] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0032] The invention provides a catheter elastic expansion fixer for gastrointestinal surgery, which mainly includes a main fixing part, which is used to fix one end of the catheter outside the body, because the other end of the catheter is inserted into the body. Such as figure 1 , the main fixing part includes a ring-shaped bladder band 20 that can be closed and tightened around the head. The bladder band 20 has an inflation port and will expand and become larger when inflated, thereby being fixed on the head. In ad...

Abstract

The invention relates to the field of gastrointestinal catheter installation, and discloses a gastrointestinal surgery catheter elastic expansion fixator which comprises a bag belt which is used for surrounding and hooping the head and can be folded into a ring shape, and the bag belt is provided with an inflation opening and can be expanded during inflation; an inflation part comprises an elastic air bag, a first control part and a second control part, wherein the first control part and the second control part are connected to the two ends of the elastic air bag respectively, the first control part comprises a pipe section made of hard materials, one end of the pipe section is connected with a port in one end of the elastic air bag, and the other end of the pipe section is connected with an inflation opening of the bag belt; two guide strips are correspondingly inserted into two guide grooves in the hole wall of the vent hole respectively, the guide grooves are formed close to one side of the elastic air bag, the guide grooves and two tooth gaps of the spline hole form a straight line and are communicated with each other, and the number of the tooth gaps of the spline hole is larger than that of the guide grooves; the small end of the conical spring is coaxially connected with the center of the movable plate and always has a pulling force towards the side away from the elastic air bag on the movable plate.

Description

technical field [0001] The invention relates to the technical field of catheter installation for gastrointestinal surgery, in particular to an elastic expansion fixer for catheters for gastrointestinal surgery. Background technique [0002] In clinical interventional treatment, it is generally necessary to position the catheter to prevent the position of the catheter from moving and ensure the therapeutic effect. The current method is usually to stick it to the skin with adhesive tape or directly sew it into the skin with sutures. [0003] The existing catheter fixing device is usually bonded to the human body at an oblique angle to fix the catheter. During the patient's activity, the catheter will inevitably shake, but it is acceptable as long as the shaking is not large, but the installation of the existing tape bonding method Fixed, adhesive tape bonding on the skin for a long time will increase the discomfort of the patient, and because the fixed installation is too firm...
