Automatic contrast injection device

Abstract

The invention relates to an automatic contrast injection device. According to the automatic contrast injection device, a medical tee joint is connected with a first injector, a second injector and aninfusion needle tubing and adjusts the route manners of the first injector, the second injector and the infusion needle tubing; a control device controls a first linear guide rail slider and a secondlinear guide rail slider to drive the first injector and a second injector to mutually push in air and normal saline, thereby forming and injecting size-uniform contrast bubbles stably into human bodyto achieve automation; further, a tee joint driving mechanism drives the valve body of the medical tee joint to rotate to further enhance automation; further, the automatic cooking robot is applicable to injectors of various specifications to meet the requirements on one load for multiple injection; further, the automatic cooking robot also comprises a blocking detection module, which can achieveself-locking during obstruction or displacement of the infusion needle tubing. On balance, the automatic cooking robot has the advantage of combining contrast agent and air into size-uniform and stable contrast agent bubbles and injecting the bubbles into human body, thereby achieving ultrasound contrast standardization and operation stability.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an automatic contrast injection device for cardiovascular right heart acoustics. Background technique [0002] At present, conventional echocardiography can effectively diagnose left-to-right shunt diseases, and can visually display the origin, flow direction, and flow velocity of abnormal blood flow. Right heart contrast-enhanced echocardiography can provide more detailed information on right-to-left shunts, especially in the diagnosis of intracardiac structures (patent foramen ovale, etc.) and abnormal shunts in the lungs. Anatomical and hemodynamic information. [0003] The contrast medium is injected through the peripheral vein during the right heart echocardiography. The contrast medium bubbles are larger than 10 microns, with an average of about 15 microns. They cannot pass through the pulmonary capillary network and cannot enter the left heart system. At the sa...

Problems solved by technology

However, there are many shortcomings in this operation: 1) The alternate push of the syringe is greatly hindered, which may easily lead to fatigue of the hands of medical staff, especially when multiple injections or a large number of patients are used, the formation of contrast agent microbubbles is not up to standard, which affects the judgment of the diagnostic conclusion; 2) Different medical staff have different operating techniques, especially female medical staff with weak hand strength, prone to fatigue, unstable grip of the syringe, easy to cause the syringe to fall off or the formation of microbubbles of the contrast agent is not up to standard; 3) due to the difference in operator proficiency , there is a difference in injection speed, and it is impossible to achieve standardized and stable operation
