Single-tube automatic imaging injector

Abstract

The invention discloses a single-tube automatic imaging injector for mixing and injecting of cardiography injections. The single-tube automatic imaging injector comprises an injection tube, a cylinder for driving the injection tube, an air pump for supplying air to the cylinder, and a controller; the injection tube is used for mixing and injecting an injection and comprises first and second cavities divided by a piston as well as a medical tee valve integrated to the injection tube, the first cavity may be communicated with the second cavity through a connection tube; the single-tube automatic imaging injector also comprises a first body and a second body for fixing the injection tube and intelligently regulating the injection tube so as to extract, mix and inject the injection; the injector extracts, mixes and injects an injection through the single tube; as connection with the cylinder is made, it is possible to automatically extract, mix and inject an injection under control of the controller in quicker and easier manner, the mixing effect is better, injecting efficiency is effectively improved, and burden of medical staff is relieved.

Description

[0001] The invention relates to the medical field, in particular to a single-barrel automatic contrast injection for right heart acoustic contrast. Background technique [0002] With the development of medical technology and people's high attention to physical health, imaging technology inspection methods are widely used in physical health inspections, especially for important parts such as the heart. This inspection method is safer and painless, and imaging technology inspection methods are slowly increasing. It replaces the old inspection methods such as surgery, sampling and testing. The contrast agent is injected into the affected part of the patient through the syringe syringe, and then a clear and stable inspection image is formed through the image scanning equipment, so as to correctly judge the actual state of the patient under examination and determine the direction for the treatment. [0003] The operation of the existing right heart acoustic contrast injector is com...

Problems solved by technology

[0003] The operation of the existing right heart acoustic contrast injector is complicated, and most of the contrast agents are mixed and injected manually

At present, the syringes used for manual injection of right heart acoustic contrast imaging require two syringes for contrast agent mixing or gas-liquid mixing, and cannot be mixed with a single cylinder. For example, the syringes disclosed in patents with application number 03823498.X and application number 201620581872.6 can be Automatic injection, but the mixing of the contrast agent cannot be completed in a single cylinder, resulting in a large waste of equipment, and time-consuming and labor-intensive. In addition, the current syringe mixing has the problem of insufficient mixing or separation during the injection process after mixing, because the shock physiological After the shock of salt water and gas stops, the stability of the microbubbles is poor, and the effect will deteriorate within a few seconds
