Description

Residual urine rapid drainage assay device

technical field

The utility model relates to medical equipment, in particular to a rapid drainage measuring device for residual urine.

Background technique

Voiding dysfunction is a common disease in urology. Clinical urodynamics is an important method for diagnosing voiding dysfunction. The remaining urine of patients is very important for clinical diagnosis. At present, there are mainly two methods for measuring residual urine before urodynamic examination in clinical practice. One is to scan the bladder capacity after urination by B-ultrasound, and use the formula to calculate the residual urine. The residual urine measured by this method has a large error; It is measured by inserting a urinary catheter into the bladder to drain urine through a graduated cylinder. Since most patients drink a lot of water before the examination, the outflow speed of the drainage tube is limited. This method is more reliable for patients with no residual urine or less residual urine. However, for those patients with residual polyuria, the drainage time is longer, and the urine from the upper urinary tract continuously flows into the bladder. At this time, not only the measurement results are inaccurate, but also the time is delayed.

Therefore, there is a need for a residual urine drainage measuring device, which can quickly drain the urine in the bladder and measure the amount of urine at the same time, so as to shorten the diagnosis time and ensure the accuracy of the diagnosis result.

as the picture shows:

The residual urine rapid drainage measuring device of this embodiment comprises a catheter 2, a negative pressure pump 1 and a measuring device 3 for measuring urine volume, the negative pressure pump is provided with a liquid inlet 4 and a liquid discharge port 5, and the The urinary catheter is connected to the liquid inlet 4, and the urinary catheter 2 is connected to the liquid inlet 4. When in use, the catheter is connected to the bladder through the urethra, and the negative pressure drainage of the urine in the bladder is carried out through a negative pressure pump. In the embodiment, the urine discharged from the discharge port is introduced into the container 9 through the catheter 8 for collection, and then the amount of urine is measured by the measuring device. The display screen of the scale shows that the utility model can fully overcome the shortcomings of the existing technology that the drainage speed is too slow and the urine continuously flows into the bladder during the drainage process, so that the bladder can be quickly and completely emptied, which greatly saves the time of medical staff and provides a convenient way for follow-up Provide a reliable basis for clinical diagnosis.

As a further improvement of this embodiment, the device also includes a PLC automatic control system and a liquid flow sensor 6, the diaphragm of the liquid flow sensor is arranged in the liquid inlet, and the signal output terminal of the liquid flow sensor is connected to the signal of the PLC automatic control system.
