Description
Technical Field
The utility model relates to the field of medical equipment, especially, relate to a bladder perfusion device of ration level pressure.
Background
Voiding bladder urography (VCUG) is a popular examination method for understanding bladder morphology and diagnosing infantile vesicoureteral reflux. The examination method comprises injecting a certain amount of contrast agent into bladder, observing bladder shape under X-ray fluoroscopy, determining degree of reflux and grading, and making images of urethra shape and obstruction while urination of infant.
Voiding bladder urography is an invasive examination with urethral cannulation and injection of contrast media as the primary procedure. The current main injection method is to draw contrast agent with a syringe and inject it manually directly into the bladder through a catheter. May cause discomfort to the infant and increase the risk of infection. Rapid injection of contrast media is associated with discomfort to the child and risks complications associated with rapid bladder distension causing over-pressure in the bladder. The quantitative contrast agent is injected at one time, but the quantitative contrast agent is not individually metered according to the bladder form, so that the contrast agent is excessive, the risk of damaging the kidney due to the high upper urinary tract pressure caused by the children with the reflux in the vesicoureteral is high, and the risk of damaging the kidney and causing the high pressure in the kidney or causing bacteremia and blood stream infection in some children.
