Description

Ultrasonic automatic bladder irrigation system and method

The application is divided into Chinese patent 'an ultrasonic bladder automatic flushing system and method', application number: 202011291842.9

Technical Field

The invention relates to the field of medical care products, in particular to a device for flushing a bladder by adopting ultrasonic waves.

Background

In hospital treatment, the bladder of a patient needs to be flushed regularly in order to treat bladder diseases, or to keep the bladder clean, remove bacteria and impurities in the bladder, avoid urinary tract infection and keep the urethra unobstructed. The bladder is washed repeatedly every time, frequently, even for many times every day, and the washing workload is large. For patients who keep the catheter for a long time, the urine is turbid, the sediment is more, a large amount of flocculent impurities are formed, and the continuous accumulation of the flocculent impurities can cause bladder stones, cystitis, urinary tract infection and the like of the patients.

The current traditional bladder irrigation method comprises the following steps: the catheter and the infusion apparatus are used for infusing the washing liquid into the bladder, and then the infused washing liquid is drained out of the body of the patient by using the siphon principle. By means of the flowing principle of the urethra flushing fluid, the removal of bacteria, urinary sediment crystals and the mucosa falling off from the bladder wall in the bladder can be accelerated, so that the infection caused by the growth of the bacteria is reduced. The traditional bladder cleaning method has the following great disadvantages: because the patient usually adopts the lying position, when the washing liquid is slowly injected into the bladder, the catheter can only suck out the washing liquid and suspended matters due to the action of gravity in the process of flushing the bladder, but the sediment is difficult to suck out, and even impurities (bacteria, blood clots, urinary sediment crystals and the mucosa falling off from the bladder wall) attached to the mucosa of the bladder wall can not be sucked out, so that the actual cleaning effect is greatly reduced.

In order to solve the problems, the medical staff can change the body position of the patient from time to time during the washing process to make the sediment flow and suspend so as to be easier to suck out of the body. Although posture changing has certain effect, many attachments are difficult to peel off and suspend from the bladder wall through posture changing, and the physique of all patients can not meet the requirement of posture changing. The chemical medicine is used for dissolving impurities for cleaning, but the chemical medicine has certain toxic and side effects, the bladder can be damaged after long-term use, and part of patients with allergic constitution are not suitable for use. Furthermore, if a special tool is used to remove impurities, mechanical damage to the mucosa of the bladder wall is also easily caused.
