Description

Technical Field

[0001] This invention belongs to the technical field of medical ultrasound diagnostic auxiliary equipment, specifically an electric right heart acoustic contrast foaming device. Background Technology

[0002] Right heart contrast echocardiography (bubble test) is an important clinical diagnostic method for right heart function and intracardiac shunts. Its core is to observe the imaging of the right heart system after intravenous injection of a microbubble suspension formed by mixing physiological saline with air.

[0003] The commonly used clinical preparation method is to use two 10ml syringes connected by a three-way connector. Medical staff manually and alternately push the syringe plunger to mix the saline with air and form microbubbles. However, this manual operation has obvious drawbacks: First, it is inefficient, as the manual injection speed is limited and a single preparation takes 1-2 minutes, which is difficult to meet the needs of batch testing. Second, the mixing uniformity is poor, as the manual operation force and frequency are unstable, which can easily lead to uneven microbubble size and affect the imaging effect. Third, it is labor-intensive, as long-term repetitive operation can easily cause hand fatigue for medical staff.

[0004] Therefore, an electrically powered right ventricular acoustic contrast foaming device is proposed to address the above problems. Summary of the Invention

[0005] To address the problems mentioned in the background section, this invention provides an electrically powered right ventricular acoustic contrast agent foaming device, which has the advantages of high efficiency in dispensing contrast agents and uniform mixing.

[0010] By adopting the above technical solution, a stable installation space is provided for the injection components.

[0011] Preferably, the fixed base plate is provided with an injection assembly, which includes a needle tube. Fixed wings are fixedly provided on both the left and right sides of the top of the needle tube. The fixed wings are slidably provided inside the fixed base plate and the fixed top plate. A piston push rod is slidably provided inside the needle tube. The piston push rod is fixedly provided inside the first fixed frame and the second fixed frame. An injection port is fixedly provided at the bottom of the needle tube.

[0012] By adopting the above technical solution, precise control of the contrast agent injection dosage can be achieved.

[0018] By adopting the above technical solutions, the ease of operation and the accuracy of parameter settings are improved.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention adopts an electric drive structure, combined with an integrated operation panel on the left side of the base, to achieve precise control of power transmission and intuitive adjustment of parameters during contrast agent injection.
