The World’s First Automatic Midstream Urine Sample Collector

What is Whiz® Cleancatch® Midstream™

The Whiz® Cleancatch® Midstream™ is a midstream urine sample collection device, designed and clinically proven to make urine sample collection automatic, patient and staff independent, delivering a clinically proven, significantly superior and more accurate sample, which is collected more hygienically, more easily, cleanly, economically and faster than anything currently available.

Background of urine collection

The mid stream urine sample is the preferred clinical method for all urine sample collection because the first part of the urine may be contaminated with bacteria from the skin. However, it is still a challenge to experience uncomfortable pauses and the risk of contaminating the sample with the hands when collecting the middle of a flow of urine (the midstream urine sometimes referred to as MSU).A contaminated urine sample is where the urine sample cannot be analysed due to it being mixed or contaminated with bacteria other than from the bladder (e.g. from the urethra, unsterile sample containers etc). Contamination is not the same but can lead to what is called a false positive or a false negative sample.

How does the Whiz® Cleancatch® Midstream™ works

The Whiz® Cleancatch® Midstream™ (as stated in Jackson et al) "is not simply a funnel, but incorporates a flow-sensitive channel and diverter that, using urodynamic principles, excludes the initial low-flow portion of the urinary stream, thus discarding the contaminated early stream volume, and automatically collects the midstream volume without interrupting the stream." 

As there is no spillage or over-fill, neither the patient nor the staff member handling the sample experience wet hands, wet clothes or soiled bottles.
