BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a device for collecting uncontrollably released urine passing through an introducing tube into a transparent collecting device.
Users of the stated device often suffer from infectious diseases that can attack the efferent urinary passages as well as the bladder and kidneys. To counteract these infections it is known to administer antiphlogistic drugs. However, these drugs lose their efficacy after being taken for some time. Orally applied drugs are also known that acidify the urine and thus slow down the increase of germs. Both drugs have undesirable side effects that make it necessary to discontinue their application. Furthermore, the wearer is supposed to change the device every day and go for a medical examination every two weeks.
SUMMARY OF THE INVENTION
The present invention is based on the problem of providing a device of the above-mentioned type that permits the quality of the urine to be signaled so that suitable measures can be taken in time to avoid an infection or so that a doctor can be consulted in the initial stage thereof.
This problem is solved by checking the collected urine as to impending and existing germinal infections by providing indicators that are applied to a urine exposed of a control card attached inside the collecting bag, and by covering the control card on its urine-exposed side with a membrane that slows down the reception of urine, on the one hand, and works against indicator substances being washed out, on the other hand.
Any currently used device of the above-mentioned type can be provided With the control card on the inside by adhesion or welding before the collecting bag is bonded. The membrane protects the indicators from indication errors, on the one hand, since it slows down the entrance of urine. The indicators show neither the excessive concentration of germs in the first urine nor the typical deviations in the residual urine, but rather the values integrated over the entire urine content. Since the membrane also protects the indicators from being washed out, the indication values can still be read unfalsified after many hours.
With the further features described hereinafter one obtains altogether a device whose indicators permit a precise indication of measured values.
The invention will be described in more detail below with reference to embodiment examples shown in the drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows a known device for collecting uncontrollably released urine passing through an introducing tube into a transparent, emptyable collecting bag provided with attachment straps.
FIG. 2 shows a portion of the device according to FIG. 1 with a control card on the inside walling of the collecting bag, according to the invention.
FIG. 3 shows a cross-section through a portion of the walling of a collecting bag of the type shown in FIG. 2 with a simplified control card compared to that in FIG. 2.
FIG. 4 shows a cross-section as in FIG. 3 but with a modified membrane assembly.
FIG. 5 shows a portion of a rolled-up control card.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 shows a device, referred to altogether as I, for collecting uncontrollably released urine flowing via an adapter 19 connected with the body and through an introducing tube 2 into a collecting bag 3. Collecting bag 3 with two attachment straps 4 is worn on the leg and is provided at its lower tapering end 5 with a short discharge tube 6 that is clamped shut by a clamp 7 through neutralizable spring force. All objects 1 to 6 are made of flexible transparent material.
FIG. 2 shows, of device 1 as in FIG. 1, a front view of inside walling 8 of collecting bag 3, to which a control card 9 is glued before bonding. Control card 9 has at the top an indicator field 10 having various indicator sections 11 to 14 whose indicators respond to pH, nitrite, leukocyte and electrolyte values. The indicators are at first white; when later exposed to the urine they can form colors In an acidic medium, section 11 of the pH value ind
