Ultrasonic volume measuring probe and measuring method thereof

Abstract

The invention provides an ultrasonic volume measuring probe and a measuring method thereof. The ultrasonic volume measuring probe comprises a special sound head which comprises more than two array transducers, and the array transducers are fixed in the probe and radially arranged in a plane in a staggered manner. Each array transducer is controlled by a signal collection control circuit to scan a section and acquire section information so as to acquire ultrasonic echo information of more than two sections of a ball, extracts boundary information of a bladder from the echo information through an information processing system, and calculates volume of urine in the bladder to complete measuring of capacity of the urine in the bladder. The defects brought by a mechanical probe are overcome, and the ultrasonic volume measuring probe is higher in speed and higher in measuring accuracy; due to a radially-staggered arranging mode of the array transducers, under the conditions that the number of the array transducers is equal and the radius of the probe is equal, area of a single array transducer is maximum; and under same conditions, best ultrasonic focusing effect and biggest probing depth can be realized.

Description

technical field [0001] The present invention relates to an ultrasonic volume measuring probe and a measuring method thereof, in particular to an ultrasonic volume measuring probe and a bladder scanner suitable for measuring urine volume in the bladder in medical cleaning catheterization technology. Measurement methods. Background technique [0002] "Clean urinary catheterization technology" has been adopted by EU and US legislation. It has also been gradually accepted and adopted by urology in China. The key to the "clean catheterization technique" is the need to accurately measure the urine volume in the bladder. [0003] The method of measuring the urine volume in the bladder currently mainly obtains the boundary information of the bladder by the ultrasonic echo method, reconstructs the bladder structure through the boundary information, and calculates the volume of the bladder through the reconstructed bladder structure. [0004] At present, the ultrasonic probes that ...

Problems solved by technology

[0010] The mechanical method must be a structure with a liquid sound-transmitting medium on the outer cover, and there is also the problem that the probe cannot be used due to the leakage of the liquid sound-transmitting medium;

[0011] The mechanical structure is worn, which increases the mechanical error and further reduces the accuracy; and the debris or particles generated after the wear enter the liquid sound-transmitting medium, affecting the acoustic signal, and may change the viscosity of the sound-transmitting medium, affecting the operation of the mechanism; The medium also acts as a lubricant, which inevitably accelerates aging; these situations greatly limit the life of the probe
