Definitions

  • the invention relates to a device for analyzing a test fluid according to the preamble of claim 1.
  • Such devices can be used, for example, for the analysis of saliva or urine of a subject.
  • other liquids are analyzed or a sample substance to be analyzed, for example in the form of a solid, is first mixed or dissolved in a so-called leaching solution and the test liquid obtained is subsequently analyzed.
  • the analysis can be used, for example, for the detection of drugs, explosives or other substances, such as traces of nuts.
  • test fluid which can be analyzed.
  • the mixture is achieved in such a way that a sample collector with which the sample substance can be taken up is washed out in the washing-out liquid.
  • the test liquid is usually processed.
  • the test fluid can be brought into contact with a reaction partner, for example in the form of gold conjugate.
  • the treatment is also referred to as a so-called incubation.
  • the thus prepared test fluid is passed to an analysis element containing, for example, a test strip, also referred to as a so-called lateral flow assay.
  • the test strip is loaded at one end with the test fluid, which then flows through the test strip and collects in a collection pad at the opposite end of the test strip.
  • the test strip may have a nitrocellulose membrane on which test lines and control lines are arranged, which react with the test liquid and on which a reaction and thus the analysis result are readable.
  • the analysis result can be read and processed for example by means of a special electronic evaluation device.
  • the device has an input chamber, a processing chamber and an analysis element with a test strip.
  • the device also has a housing with a housing interior, in which a treatment element at least partially limiting conditioning element and an input chamber at least partially limiting input element are arranged.
  • the test strip is arranged in the housing so that it is at least partially visible from the outside.
  • the test liquid in the form of saliva of a subject can be picked up with a sample collector and introduced into the inlet chamber.
  • the sample collector is expressed so that test liquid enters the input chamber. By pushing the sample collector to the bottom of the input chamber, it is moved in the direction of the processing chamber below it.
  • the input chamber is displaced until the bottom of the input chamber ruptures, thus flowing an undefined amount of the test fluid from the input chamber into the processing chamber.
  • a slide arranged between the processing chamber and the test strip is opened so that the conditioned test liquid can reach one end of the test strip.
  • the analysis result on the test strip can then be read as described above.
  • An opening of the input element is arranged perpendicular to the test strip.
  • the device has a processing chamber in the form of a mixing chamber and an analysis element with a test strip.
  • test liquid is filled from a separate washout in the processing chamber, from which it is passed to the test strip after preparation.
  • To fill a certain amount of test fluid into the processing chamber it has a level mark up to which a user of the device is to fill test fluid. It is not possible to monitor or check the amount of test fluid actually filled in.
  • the device according to the invention for analyzing a test fluid has an inlet chamber, a treatment chamber and an analysis element.
  • the device also has a housing with a housing interior, in which a treatment element at least partially limiting conditioning element and an input chamber at least partially limiting input element are arranged.
  • the test strip is arranged in the housing so that it is at least partially visible from the outside.
  • the input chamber is intended to receive the test fluid. Test fluid can be transferred from the input chamber to the analysis element via the treatment chamber.
  • the housing interior is cylindrical and the treatment element is rotatable relative to the input element and the housing.
  • This makes it possible to make the housing very compact, in particular with a cylindrical or cuboid outer contour.
  • the device is also easy and reliable to handle, since the various necessary for the analysis positions of the individual components to each other by a simple rotation of the processing element relative to the input member and the housing are adjustable.
  • the analysis element has one or more test strips which are arranged in the axial direction of the housing.
  • the treatment element and the input element each have a mainly hollow cylindrical basic shape and the input element is disposed within the treatment element.
  • the housing, the treatment element and the input element are designed and arranged so that in an initial position, the input chamber and the processing chamber are separated from each other.
  • a filling position is adjustable, in which the treatment chamber is connected to the input chamber and separated from the analysis element.
  • an analysis position is adjustable, in which the treatment chamber is connected to the analysis element. This allows a particularly compact design of the device and a particularly simple handling.
  • the rotation of the processing element from the starting position into the filling position and further into the analysis position takes place in particular in only one direction of rotation. It is possible that for safe adjustment of the various positions detents between the housing and processing element are provided, which fix the processing element in the individual positions, but can be suppressed.
  • the processing element may have one or more recesses and the housing correspondingly positioned elevations.
  • the detents can also be provided between the housing and a component connected to the treatment element, with which, for example, a force for rotating the treatment element can be introduced.
  • the input chamber is separated from the analysis element in the analysis position. This prevents further test liquid from flowing during or after preparation and thus influencing the analysis result.
  • the input element and the housing are rotatably connected to each other. This is necessary to adjust the various positions only a rotation of the treatment element. This allows a simple construction and easy handling of the device.
  • a treatment position is adjustable, in which the processing chamber is separated from the input chamber and the analysis element. This prevents further test liquid from flowing during or after preparation and thus influencing the analysis result. This makes very precise analyzes possible.
  • the input chamber has at least one passage in the direction of the treatment element and the treatment chamber is designed as a continuous recess in the treatment element. This allows a particularly simple and inexpensive construction of the device.
  • the recess of the treatment element By rotating the treatment element from the starting position relative to the input element and thus opposite the input chamber, the recess of the treatment element can be positioned so that it overlaps with said passage of the input chamber and is thus connected to the input chamber. This is the case in the filling phase, in which then fills the recess and thus the processing chamber with test liquid from the input chamber.
  • the inlet chamber and the treatment chamber are designed so that the treatment chamber is completely filled. Since the recess has a defined size, the treatment chamber contains a defined amount of test fluid after filling. This ensures a defined preparation of the test fluid and thus an accurate analysis result.
  • the analysis element has more than one test strip, in particular for each test strip a separate passage of the input chamber and a separate recess of the treatment element and thus a separate processing chamber are provided.
  • This makes it possible in an advantageous manner to be able to process the test liquid differently in the different processing chambers.
  • For this purpose for example, be contained in the different test chambers different reactants.
  • the input member After filling, the input member is further rotated until the analysis position is reached, in which the recess of the input member does not overlap with the passage of the input chamber.
  • the device has a plug, which can be inserted into an opening of the treatment element.
  • a force for rotating the treatment element can be introduced via the plug.
  • the input chamber can be closed in an initial state of the device and so contamination of the input chamber, which could falsify the analysis result, can be prevented.
  • an initial state of the device should be understood to be an unused state, that is to say the state before the start of an analysis of a sample substance or a test fluid.
  • the plug can additionally be used to adjust the various positions of the treatment element necessary for the analysis of the test fluid.
  • the stopper and the said opening of the treatment element have corresponding cross sections in the form of a so-called equal dia.
  • the plug and the opening are made conical, in particular in the axial direction. When inserting, this causes the stopper to self-center in the opening. Thus, the plug can be easily inserted into the opening and it is still a good power transmission from the plug to the treatment element guaranteed.
  • An equal thickness is a closed line that always touches all four sides in any position within a suitable square.
  • the cross section may also be referred to as a so-called harmonic polygon profile with a so-called continuous P3 shape curve.
  • the plug has a sample collector. Thus, only a few parts are necessary for the device.
  • the plug has a storage cylinder.
  • the storage cylinder contains in the initial state of the device leaching.
  • the leaching liquid can only be filled in the input chamber when it is really needed, without providing for the leaching a separate container. For example, if the plug was removed with the sample collector to take a sample, there is still no leaching in the input chamber, which could leak out unintentionally.
  • the plug has a base body with a mainly cylindrical inner contour and a relative to the main body immovable inner part.
  • the inner part dives when inserting the storage cylinder into the main body in the storage cylinder and closes the storage cylinder in a start position. It also has a connecting line, which is connected after leaving the starting position with the storage cylinder and over which is inserted in the plug leaching fluid into the input chamber can be conducted. This allows in a very simple manner, the feeding of the leaching into the input chamber. This only needs the supply cylinder in the direction Input chamber are pressed and thus pushed onto the inner part.
  • the inner part and the base body of the plug can consist of either one or more parts, in particular two parts.
  • the storage cylinder has an inner circumferential sealing lip on which the inner part of the base body is present in the starting position and thus concludes the storage cylinder.
  • the connecting line has a radial section and an axial section which are designed such that after the radial section has at least partially passed over the sealing lip of the storage cylinder, leaching fluid can be pressed out of the storage chamber via the radial section into the axial section. This allows a particularly simple construction of the plug.
  • Said radial section does not have to be exactly radial; it is sufficient if it has a radially inward component from one edge of the inner part, so that leaching fluid can flow inward from the edge of the inner part to the axial section.
  • the axial section also does not have to be exactly aligned axially. It is sufficient if it is designed so that it can guide leaching fluid from the radial section in the axial direction in the direction of the inlet chamber.
  • the axial section runs in particular at least partially in a shaft of the sample collector.

  • a connection between the inlet chamber 19 and the treatment chambers can be established via the two passages 20, 21.
  • the stopper 12 closes on the one hand with an inner part 22, the input chamber 19 and is used on the other with an outer part 23 in an opening 42 of the treatment element 17.
