Problems solved by technology

Its disadvantage is that the measurement part is composed of multiple probes, so the volume is large and the cost is high; during the measurement process, the probe group needs to be continuously moved to obtain the final measurement value, so additional manual operations are required, which cannot be realized automation

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] in such as figure 1 In the shown embodiment of the urinary bladder volume measuring device of the present invention, the support frame 4 and the motor 6 are fixed on the base 7, and the probe clamp 2 holds the upper end of the A-type ultrasonic probe 1 with a transmission frequency such as 2.5 MHz , the output torque of the motor 6 is transmitted to the probe clamp 2 through the transmission shaft 5, thereby driving the probe 1 to reciprocate and swing, and the swing angle range is [-45°, 45°]. The support rod 3 fixes and balances the probe clamp 2 .

[0025] according to figure 1 In one embodiment of the present invention shown, there is an elongated opening b on the base 7 . The probe 1 is in contact with the skin of the subject through the opening b, and the opening b enables the probe 1 to vibrate while ultrasonically co...

Abstract

The invention provides a device and a method for measuring the accumulative urine volume of a urinary bladder. The device fixes an A-type ultrasonic probe at a specific position of the low abdominal wall of a human body by a probe fixture, a support frame and a base, wherein the probe swings in a plane under the drive of an electric motor; the position of the base is adjusted, so that the swinging plane of the probe is positioned on the central sagittal plane of the human body; when swinging, the probe aims at the urinary bladder to emit and receive ultrasonic waves once at the angular interval of 15 degrees to form a plurality of ultrasonic beams; and the anteroposterior diameter D and the axial diameter H of the urinary bladder are calculated according to the number of the ultrasonic beams penetrating the urinary bladder and corresponding angles, and the accumulative urine volume of the urinary bladder is calculated according to the formula V=D*H*K. The device of the invention has the characteristics of low A-type ultrasonic probe cost, simple structure, automatic operation from the beginning of the measurement process without human intervention, high degree of automation, and capability of ensuring the effective propagation of signals as the probe is in contact with skin by an ultrasonic coupling agent.

Description

technical field [0001] The present invention relates to a device and method for measuring bladder urine volume, more specifically, it relates to a device and method for measuring bladder urine volume using ultrasonic technology. Background technique [0002] US patent specification US-0215896A1 discloses a device and method for obtaining urine volume in the bladder using a limited ultrasound beam. The device places multiple ultrasonic probes with preset positions and angles on the lower abdomen of the human body, calculates the upper and lower diameter H and the front and rear diameter D of the bladder according to the transmitted and returned ultrasonic information, and then according to the formula V=D×H×K Bladder urine volume is calculated, where K is a correction factor determined by the degree of filling of the bladder. Its disadvantage is that the measurement part is composed of multiple probes, so the volume is large and the cost is high; during the measurement proce...
