Definitions

  • the invention relates to a device for measuring the properties of an endogenous fluid of the type specified in the preamble of claim 1.
  • a change in the natural equilibrium to the detriment of the miic acid content leads to a measurable change in the pH.
  • test strip proposed in this form and provided on the examination glove for the examination of the vaginal milieu, disadvantageous evaluations often result in evaluations by the patient, or at least difficulties in the qualitative evaluation of the test strip used.
  • the invention is therefore based on the object of specifying a device which is suitable for examining the body's own fluids, in particular vaginal fluid, and which can be evaluated without particular effort and with relatively great accuracy and with simple means is inexpensive to manufacture.
  • the invention includes the observation that, in a packaging of best of an elastic material ⁇ Henden protective clothing manufacturing technical means Vor ⁇ parts are accessible when the additional elements by gluing are connected to the protective clothing agent.
  • the invention further includes the knowledge that the more qualitatively the test strip is attached to a color support with the color values to be compared, the more convenient and the more precisely it can be carried out based on a color change is. If, in addition, the background color is adapted to the starting or normal color of the indicator and the area of the indicator that is not covered by the cover bearing the background color has the form of an attention symbol in a positive or negative representation, a color change represents a hazard or warning , which can even be grasped by one of the addressees who are unfamiliar with reading and writing without further thought. This also applies to inscriptions such as "Caution” and "Warning" because these inscriptions have the same effect.
  • the slip-on, elastic protective clothing for carrying out pH measurements of the vaginal fluid in gynecological examinations of the vagina has a test strip to be used for the pH measurement, which is attached to the surface with a double-sided adhesive tape Protective clothing is attached.
  • the test strip has a carrier provided with an indicator, which in turn is connected to one of the two adhesive layers of the double-sided adhesive tape.
  • test strips made of the most varied of materials can be attached quickly and securely.
  • the protective clothing used does not have to be prepared in any special way beforehand in the areas intended for gluing.
  • the protective clothing according to the invention has two variants, one of which is intended for the doctor and the other for the patient herself. The differences and advantages of the two solutions are described in more detail below.
  • the double-sided adhesive tape is advantageously suitable for positioning the test strip on a slip-on, elastic protective clothing which is used when examining a body's own fluid, for example for measuring the pH of the vaginal fluid during gynecological examinations of the vagina.
  • a labeled color gamut provided fens to determine the current pH value by comparison with the color of Teststrei-.
  • the border area for em is advantageously m on the color scale of the vaginal milieu so that even a layperson can qualitatively recognize a disease.
  • the test strip on its side facing the body area to be examined has a cover which partially covers the layer of the indicator agent which reacts to a pathological change in the body area to be examined with a color change.
  • neutral surface sections are advantageously located in the immediate vicinity of the partial surfaces of the indicator medium layer reacting with color change, which by special design, in particular coloring, for analysis of the color change or corresponding partial surfaces of the indicator surface * '. 'can be used.
  • the cover located on the indicator medium layer of the test strip is designed as a template in the form of a monochrome, opaque film, in which, for example, circular or rectangular recesses are provided. With the body fluid, these recesses give chemically reacting surfaces of the Layer of the test strip free and are completely enclosed by color-neutral film sections.
  • the film-shaped cover is attached to the indication medium layer in a simple manner by gluing.
  • the cover has an em coloration which preferably corresponds to the color shade that the indicator medium layer assumes when the vaginal fluid has a pH value which can be assigned to the healthy vaginal milieu.
  • the cover has a labeled color scale, which extends parallel to the longitudinal axis of the test strip and is arranged next to the recesses.
  • the color comparison between the coloring in the recesses and the color scale leads in a simple manner to the current pH value of the vaginal milieu.
  • the color assignment can be selected for an examination of other body fluids or secretions.
  • test strip according to the invention is particularly suitable for medical laypersons, since even a slight scar change in the areas of the indicator medium layer that are located can be easily recognized by direct comparison with the color of the cover.
  • exact quantitative evaluation of the color change can be carried out after the above-described early detection of the medical examination.
  • the recesses provided in the cover form an icon.
  • This symbol is designed, for example, as a warning or exclamation mark or as a lettering for a warning.
  • a plurality of test strips of the same design are detachably fastened in a serial arrangement on a carrier strip.
  • the carrier strip is wound up into a tear-off roll and each has a predetermined separation point between two successively arranged test strips.
  • the double-sided adhesive tape carrying the test strip there is a section on both sides that is adhesive-free and designed as a grip tab.
  • This enables the test strip to be handled comfortably when assembling the protective clothing means with the for the test strips required for the examination.
  • the indication medium layer of the test strip does not have to be touched by hand in order to be able to position it at the selected location. This avoids influencing the indication medium layer, which could possibly lead to a falsification of the examination result and would make a new examination necessary.
  • the protective clothing is designed as a finger cot.
