Single-barrel automatic angiography injector

Abstract

The invention discloses a single-tube automatic radiography injector, which is used for mixing and injecting medicaments for cardiac radiography injection. In the mixing and injection of injection medicines, it includes the first cavity divided by the piston, the second cavity and the medical three-way valve integrated with the injection barrel. The first cavity can be connected with the second cavity through the connecting tube. It also includes a first main body and a second main body, which are used to fix the syringe and intelligently control the extraction, mixing and injection of the medicine by the syringe. The syringe completes the extraction, mixing and injection of the injection medicine in a single barrel, and is connected to the cylinder The extraction, mixing and injection of medicaments can be completed automatically through the control of the controller, which is faster and labor-saving, and the mixing effect is better, which can effectively improve the injection efficiency and reduce the burden on medical staff.

Description

technical field [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 contr...

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 syringe used for manual injection of right heart acoustic contrast requires 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 injected automatically , but the mixing of the contrast agent cannot be completed with a single cylinder, resulting in a great waste of equipment, and time-consuming and laborious. In addition, the current syringe mixing has the problem of insufficient mixing or separation again during the injection process after mixing, because oscillating normal saline and After the gas shock stops, the microbubble stability is poor, and the effect will be deteriorated in a few seconds
