Double-layer closed sacculus tube for digestive tract

Abstract

The invention discloses a double-layer closed sacculus tube for the digestive tract. The double-layer closed sacculus tube comprises an inner-layer sacculus and an outer-layer sacculus which are coaxial and concentric and have different wall thicknesses, wherein the inner-layer sacculus is sleeved by the outer-layer sacculus; the inner-layer sacculus and the outer-layer sacculus are fixedly connected with the head part of a catheter in a sealed mode; the catheter is ofthe structure of sleeving three single-cavity tubes together; and two sides of the tail of the catheter are respectively connected with two sealing connectors, wherein one sealing connector is communicated with the injection hole of the inner-layer sacculus, and the other sealing connector is communicated with the injection hole of the outer-layer sacculus. According to the three-cavity double-layer sacculus catheter with the closed cavities, the double layers of sacculi are adopted, the pressure of the inner-layer sacculus and the pressure of the outer-layer sacculus are different, the inner-layer sacculus is used for hemostasis by compression and adhesion prevention, and the outer-layer sacculus is used for the filling display of the digestive tract. The whole catheter contains a developing material, so that the position of the catheter in the digestive tract can be distinguished under X rays, CT, MRI and ultrasound. Guide wires can be inserted from a wire guide hole, for pushing the catheter to reach a set position in the digestive tract easily, and the operation is simple and feasible.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a double-layer airtight balloon tube used for improving the quality of imaging examination of human digestive tract, developing a new examination method and for preventing adhesion and compressing hemostasis of the cavity. Background technique [0002] Human cavity disease is a common and frequently-occurring disease, and it has a tendency to increase gradually. However, due to the physiological structure of the human intestinal tract, it is an anatomically soft, deformable and irregular structure. The diagnosis and treatment of the disease has always been a medical difficulty. Without the help of external equipment and comparison, the quality of imaging diagnosis and treatment is low, so it is more necessary to develop simple, effective, cheap and serialized equipment. [0003] Chinese patent CN102793965A provides a rectal balloon catheter for rectal lesion inspection,...

AI Technical Summary

Problems solved by technology

The outer balloon of the above-mentioned double-layer balloon catheter is made of a unique microporous membrane, which is not airtight and cannot fulfill the function of filling the cavity of the human body after being filled with gas or liquid

[0005] At the same time, the catheter of the above-mentioned intestinal balloon catheter is made of polyvinyl chloride, and the polyvinyl chloride product contains plasticizers, and the plasticizers currently used are mainly phthalate compounds. The system has a damaging effect, which can cause multiple neuritis, insensitivity, numbness and other symptoms, and phthalates also have inhibitory and anesthetic effects on the central nervous system
