Description

Anti-pollution portable urinary calculus collector

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a urinary calculus collector that prevents urine pollution and can hand-carry.

Background

Urinary calculus, also known as urolithiasis (urolithiasis), is one of the common diseases in urology and occupies the first place among hospitalized patients in urology. The incidence rate of urinary calculus in China is 1% -5%, the incidence rate is increasing in recent years, and the annual new incidence rate is about 150-200/10 ten thousands of people. Upper urinary tract stones can cause obstruction of the nephroureter, and not only can serious renal colic occur, but also long-term persistent obstruction can cause renal impairment. 60% -80% of ureteral calculus can be naturally discharged out of the body through conservative treatment, especially ureteral calculus with small volume, and researches show that 98% of ureteral calculus with the diameter of less than 5mm can be automatically discharged out of the body.

At present, minimally invasive treatment is the mainstream of urinary calculus treatment, wherein extracorporeal shock wave lithotripsy belongs to a non-invasive treatment method, has the advantages of safety, high curative effect, small damage, few complications, quick recovery and the like, and becomes one of the first-choice methods for treating upper urinary tract calculus. In the extracorporeal shock wave lithotripsy, shock waves are generated by an extracorporeal lithotripter, are conducted to calculi after being focused by equipment, and the calculi in a urinary tract are crushed by shock energy so as to be discharged out of the body along with urine.

The patient who receives conservative treatment or external shock wave lithotripsy treatment observes whether calculus is discharged from urine, and has important significance for judging the treatment result. Although most patients have symptoms such as angina, macroscopic hematuria, lower urinary tract irritation and the like in the process of discharging the calculus, the exact discharge time of the calculus is difficult to predict, the discharged calculus is small in volume and difficult to distinguish in a rapid urine flow, and whether the calculus is discharged or not is difficult to observe by naked eyes in the process of discharging the calculus, and a calculus sample is difficult to collect.

Urinary lithiasis is not only high in prevalence rate, but also quite high in recurrence rate. The presence of calculus is not the cause of the disease as it develops. Only when a calculus sample is obtained and then calculus component analysis is completed can the cause of calculus formation be determined, and then targeted treatment is carried out according to the etiology, so that recurrence of calculus is effectively prevented. Therefore, the collection of the calculus specimen has important significance for the treatment and prevention of calculus.

The urolithiasis patient cannot determine the timing of stone expulsion, in fact, stone expulsion is possible during each urination, if the patient tries to collect a stone specimen, the patient must carry with him or her a stone collector, and the stone collector is tried to be collected during each urination. Current calculus collection device all adopts open filter screen structure, mainly has following shortcoming:

1. the open filter screen structure can easily cause the urine to splash and pollute the surrounding environment and clothes during the process of collecting the urine when in use.

2. After the urine collection device is used, residual urine in the container is difficult to discharge completely within a short time, and if the urine collection device is carried about, the residual urine is easy to leave out of the container, pollutes the surrounding environment and clothes, and is inconvenient to carry about for daily use.

3. The open filter screen structure, after using, the urine that remains in the container also produces peculiar smell easily, if hand-carry, peculiar smell can cause patient and people around uncomfortable.

4. If the open calculus collector is carried with a person, the calculus collector needs to be cleaned in time after being used every time to avoid pollution and reduce peculiar smell, so that the use is inconvenient. And residual liquid after cleaning still adheres to the container, so that the container is easy to pollute and wet the surrounding environment and is inconvenient to carry continuously.

5. The existing stone collector has large volume, is only suitable for household or hospital environment, is inconvenient to carry, can discharge stones after a patient goes out, and cannot effectively collect the stones.
