A wireless handheld bladder scanner

Abstract

The invention discloses a wireless handheld bladder scanner. The wireless handheld bladder scanner comprises a wireless ultrasonic probe and a tablet personal computer or a smart phone; the wireless ultrasonic probe is formed by sequentially connecting an ultrasonic array element, a waveform emission controller, a motor driving device, a signal amplifier, an AD sampler, a main controller and a wireless transmission module. The wireless handheld bladder scanner has the characteristics that the volume of urine in bladder can be accurately calculated, and a user can operate conveniently; the wireless handheld bladder scanner is suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a wireless handheld bladder scanner. Background technique [0002] The amount of residual urine in the patient's bladder affects the infection of the urinary system and the abnormality of renal function. This is an item that must be paid attention to in the care of patients with spinal cord injuries, pelvic surgery or other patients with bladder nerve damage for many years. At present, experts at home and abroad agree that intermittent catheterization is the first choice for the treatment of neurogenic bladder dysfunction. The ideal intermittent catheterization should be based on bladder urine capacity, that is, within the patient's safe capacity range, the maximum bladder capacity should be achieved as much as possible. Most of the traditional methods use percussion, but the accuracy is poor, with uncertainty and blindness, and it has a lot to do with the doctor's experie...

AI Technical Summary

Problems solved by technology

The ultrasonic echo signal collected by the ultrasonic probe is very weak (microvolt level), and such a weak analog signal is transmitted to the host through a cable (the cable length is generally 1 meter to 1.5 meters), which is very vulnerable to electromagnetic interference in the external environment , and the interference of the motor control signal transmitted simultaneously with the cable, which affects the imaging quality of ultrasound and ultimately affects the accuracy of bladder volume measurement

At the same time, the existence of the connecting cable restricts the user during use, and the ultrasonic probe and the host cannot be moved at will, limited by the length of the cable.
