Definitions

  • the present invention relates to an analysis device, intended for the analysis of samples of liquids.
  • reagents intended for the analysis of samples of liquids, are presently presented in the form of strips or rods.
  • these strips or sticks comprise at least one reaction zone, impregnated with one or more suitable reactive products, which zone is brought into contact with the liquid to be analyzed, either by direct immersion or by capillarity.
  • the result of the analysis which generally results in a change in appearance of the reaction zone, is read directly on this zone.
  • This presentation offers many advantages: it allows a quick and simple analysis, replacing a whole series of manipulations by simply dipping a strip in the liquid to be analyzed; it is therefore particularly well suited to the implementation of large-scale analyzes, as well as to the analysis by unqualified persons, or in places where only limited equipment is available. , for example analyzes in the field, or carried out by an individual at his home.
  • reagent strips intended for diagnosis in the medical field. These strips are used for the identification or the determination of different substances present in biological fluids, in particular urine.
  • the reagents in strips or sticks are generally designed to give a rapid result, it is necessary to leave them for a certain time, which is of the order of a few minutes, in contact with the liquid to be analyzed; a problem is then posed by the holding the strip or stick in the liquid; this problem can, in certain cases, be solved by placing one end of the stick or the strip at the bottom of the container containing the liquid to be analyzed; however, this holding system is unstable, and does not allow the level of immersion of the strip or the stick to be easily adjusted in the liquid; or it may be important to precisely adjust this level, in particular in the case of certain strips or sticks where the reaction zone is supplied by capillary action but must not be immersed in the liquid.
  • the object of the present invention is to provide a solution to this problem, by proposing a means for holding the strip or the stick in the liquid to be analyzed.
  • the present invention relates to a device for the analysis of liquid samples, which device is characterized in that it comprises the combination of a strip or a stick comprising at least one reaction zone, and means suitable for maintaining a determined portion of said strip or of said stick in immersion in the liquid to be analyzed.
  • said holding means consist of the container containing the liquid to be analyzed, and the strip or the stick is provided with at least one member for securing to said container.
  • the member for securing the strip or the stick to the container consists of a cover, placed on the rim of said container, and provided with at least one orifice allowing the passage of the strip or stick.
  • the member for securing the strip or the stick to the container consists of an adhesive zone located near the end of the strip or stick opposite to that immersed in the liquid.
  • the member for securing the strip or the stick to the container consists of a clamp, fixed in the vicinity of the end of the strip or of the stick opposite to that immersed in the liquid.
  • the end of the strip or of the stick opposite to that immersed in the liquid is provided with an arm moving said strip or said stick away from the wall of the container.
  • Said arm can advantageously be formed by folding of said end.
  • the means for holding the strip or the stick are independent of the container containing the liquid to be analyzed.
  • This embodiment has the advantage of allowing the strip to be held without having to adjust the position thereof as a function of the dimensions of the container.
  • said holding means is constituted by a float.
  • the reagents used in the examples which follow, and represented in the corresponding figures consist of a plastic strip, on which is adhered a fibrous and absorbent material; several zones are individualized along the length of the strip; a zone (1) which is intended to be immersed in the liquid to be analyzed; a reaction zone (2), which is impregnated with suitable reactive substances; a zone (3) intended for the manipulation of the strip or the stick by the user.
  • the device shown in Figure 1 consists of a cover (4), pierced with an orifice (5) allowing the passage of the strip.
  • the cover is placed on the container containing the liquid to be analyzed; the strip is slid into the orifice, and can slide therein; its position can thus be adjusted in height, depending on the level of the liquid.
  • the upper part of the strip which corresponds to the area allowing the manipulation of said strip by the user, is folded back on itself by two folds (6) (7).
  • the zone delimited by the edges of the 2 successive folds forms an arm (8), which allows the submerged zone and the reaction zone to be moved away from the internal wall of the container.
  • the area delimited by the edge of the second fold and the upper end of the strip is provided with an adhesive (9), which makes it possible to fix the strip or the stick on the wall of the container, at the desired height.
  • the upper part of the strip which corresponds to the zone allowing the manipulation of said strip by the user, is folded in a zigzag by two folds (10) (11).
  • the zone delimited by the edges of the 2 successive folds forms an arm (12), which allows the submerged zone and the reaction zone to be moved away from the internal wall of the container.
  • the area delimited by the edge of the second fold and the upper end of the strip, is fitted with a clamp (13), which allows the strip to be fixed to the edge of the container.
  • the device shown in Figure 4 consists of a float (14), made of a suitable material, such as a rigid foam, and pierced with an orifice (15) allowing the passage of the strip.
  • the strip is slid into the hole, and positioned as desired; the device is then deposited on the surface of the liquid.
  • the float is here placed between the submerged zone and the reaction zone, which protects the latter from contact with the liquid to be analyzed, and also allows easy reading of the result.
