Dynamic urinary bladder pressure volume monitoring device

Abstract

The invention relates to the technical field of medical auxiliary equipment, in particular to a dynamic bladder pressure and volume monitoring device. It includes a urinary catheter, a monitor, a computer control terminal and a solenoid valve, wherein the monitor includes a bladder pressure monitor, a pressure monitor at the sphincter and a bladder volume monitoring probe, and the bladder pressure monitor and the bladder volume monitoring probe It is integrated and fixed at one end of the urinary catheter, and the pressure monitor at the sphincter is fixed and distributed on the front outer side of the urinary catheter. The advantage of the present invention is that it can dynamically monitor the volume and pressure changes of the bladder and the pressure changes at the sphincter in a timely manner under the physiological state, and integrate the signals through a computer to obtain the dynamic pressure-volume change curve under the relevant physiological state.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a dynamic bladder pressure and volume monitoring device. Background technique [0002] Urination (micturition) is a complex reflex activity controlled by the central nervous system. After the urine is produced by the kidneys, it is temporarily stored in the bladder through the ureter, and after a certain amount is stored, it is excreted through the urethra one at a time. [0003] Due to certain diseases, the central nervous system or peripheral nerves that control the voiding function of the patient are damaged and the bladder urethra dysfunction is called neurogenic bladder. Urinary incontinence or urinary retention is one of the most common symptoms, and the resulting urinary complications, such as upper urinary tract damage and renal failure, are the main causes of death in patients. The evaluation of bladder detrusor and sphincter changes is crucial to t...

AI Technical Summary

Problems solved by technology

However, in the case of sudden expansion or temperature changes, the bladder will produce involuntary contraction, which seriously affects the accuracy of the obtained data, and often a single measurement cannot reflect the overall change of the patient's bladder

Therefore, doctors cannot obtain the dynamic changes in bladder pressure and volume under physiological conditions based on traditional monitoring devices.
