CN1419939A - Spiral CT three-D simulation endoscope contrast medium and producing method thereof - Google Patents

Abstract

A gastrointestinal contract medium for the spiral CT machine using 3D reconstruction technique is prepared from edible atoleine, tragacanth gum, arabic gum, stervioside and distilled water through mixing, colloid grinding, diluting, filtering, deodourizing, homogenizing, emulsion, and high-temp sterilizing. Its advantages are clear imaging, high stability, long quality guarenttee period and no toxic by-effect.

Description

A kind of spiral CT three-D simulation endoscope contrast medium and production method thereof

Technical field

The gastrointestinal contrast agent of special use when the present invention relates to spiral CT machine employing three-dimensional reconstruction technology, and production method.

Background technology

Based on the gastrointestinal anatomical features, gastrointestinal tract provides ideal prerequisite and normal gastrointestinal tract to be the high density video picture in image can not for the CT video picture of axle position, in the diagnosis of scans image, be easy to high density focus (occupancy and hemorrhagic pathological changes) and form isodense image, making clinical diagnosis obscure difficulty distinguishes, therefore increase the paired observation of intestines and stomach and surrounding tissue by means of contrast agent, finish clinical diagnostic imaging.

Summary of the invention

The objective of the invention is needs, a kind of patent contrast agent and production method thereof are provided according to the Spiral CT scan diagnosis.

Spiral CT three-D simulation endoscope contrast medium of the present invention and production method thereof are:

The Main Ingredients and Appearance of this contrast agent is edibility liquid paraffin 70-98%, tragacanth gum 1.0-1.5%, arabic gum 0.3-0.6%, stevioside 0.1-0.9%, all the other are distilled water; Colloid mill is carried out in each component mixing stirring be ground to granularity 0.005-0.02mm, with distilled water diluting to 100%, carry out ultra-clean filtration and high temperature dispelling abnormal flavor then, carry out emulsifying again, homogenization pressure is 2.5-4Mpa, and final high temperature sterilization, packing get final product.

The characteristics of this contrast agent are, behind the full gastrointestinal tract, form a negative 100HU contrast gradient with the high density focus, actual size, form, position that can clear observation space and the solid of adjoining organ are dissected, make the axle position of stomach, the Virtual Endoscopy single pass of three-dimensional stomach function regulating is finished.Gastroscopy and non-occupancy patient diagnosis are feared in the special adaptation of this product, have good stable, and long shelf-life has no side effect.
