Quality control detection training phantom for bladder capacity measuring instrument and manufacturing method of quality control detection training phantom

Abstract

The invention discloses a quality control detection training phantom for a bladder capacity measuring instrument and a manufacturing method of the quality control detection training phantom and belongs to the bladder capacity measurement field. The quality control detection training phantom comprises a simulated human body pelvic cavity model and a plurality of bladder inserts; the simulated humanbody pelvic cavity model is provided with insertion openings for accommodating the bladder inserts; and simulated bladders of different capacities and shapes are arranged in the bladder inserts. Themanufacturing method includes a 3D printing file generating step, a printing step, a simulated human body pelvic cavity model casting step and a bladder insert casting step. The quality control detection training phantom can be used to accurately monitor the training operation of bladder capacity measurement and meet the accuracy, repeatability, linearity and other indicators of an ultrasound bladder capacity measuring instrument during radiotherapy.

Description

technical field [0001] The invention is used in the field of bladder capacity measurement, and in particular relates to a quality control detection training phantom for a bladder capacity tester and a manufacturing method thereof. Background technique [0002] On the one hand, ultrasonic bladder capacity measuring instrument has been widely used in clinic because of its convenient, fast, non-invasive and real-time measurement results: such as the understanding of bladder function before and after surgery anesthesia; evaluation of abdominal, pelvic or spinal nerves after surgery. Influence of system damage on bladder function; judging acute urinary retention; guiding urinary catheterization, protecting and training bladder function; verifying the cause of no urine after catheterization; determining the timing of urination in bedridden patients, etc. [0003] On the other hand, in recent years, with the rapid development of radiotherapy technology, precision radiotherapy techn...

AI Technical Summary

Problems solved by technology

During the clinical use of radiotherapy, it was found that there are many factors that affect the accurate measurement of the ultrasonic bladder volume meter, such as different bladder shapes, bladder capacity, subcutaneous fat thickness, changes in the orientation of the probe, and the proficiency of the operator, etc., which may affect the accuracy of the measurement. Significant impact on accuracy, repeatability, etc.
