Definitions
- the invention relates to a container for receiving laboratory samples, which can be used in particular in the forensic evidence collection, but also for receiving other laboratory samples in e.g. medical or molecular biological field or the like is suitable.
- the sampling is done with a set consisting of a tube and a rod held by a plug or other closure fitting on the tube, to the free end of which a cotton ball or the like for sampling, e.g. a cheek swab, is attached.
- the tube and the rod are coordinated so that the closure can be placed on the tube, in which case the rod protrudes into the interior of the tube and its intended for sampling imaginary free end, z.
- the cotton ball is held in a defined height range of the tube and usually without contact with the inner wall of the tube.
- a sample is not worked up immediately after its recovery. Rather, some time passes for different reasons before the sample is processed further. Especially in the field of evidence but also in principle in genetic or microbiological studies it is of particular importance that the sample no longer undergoes any change after it has been removed until it has been worked up. Changes in the sample material are to be expected in particular if the sample is moist and not cooled.
- WO 00/51496 shows a system in which a sampling tube has in the longitudinal direction two compartments, namely a lower compartment filled with desiccant and an upper one in which the sample is placed.
- a similar device is shown in GB 2358061.
- the object of the invention is, starting from the prior art, to provide a container for receiving laboratory samples in which compared to known systems a faster and more effective drying is possible.
- a drying device is provided laterally at least partially surrounding the sample in at least the height range in which the sample is arranged in the container after it has been obtained.
- sample in the context of the present application comprises not only the actual sample material but also the sample material-containing device for sample collection, for example the cotton ball at the end of the above-mentioned holding staff.
- the drying device contains desiccant and is designed such that the desiccant contained is in gas exchange with the sample, e.g. with a cotton swab soaked in test liquid, and then it dries.
- the desiccant is e.g. hygroscopic substances, e.g. Zeolite, silica gel or molecular sieve, to name just a few examples.
- the known and the inventive system are closed systems, d. H. After the sample has been taken, the container is sealed airtight with the closure carrying the rod-shaped sampling device. In such a hermetically sealed container is assumed to be a standing column of air, d. H. a gas exchange takes place only by diffusion and therefore over longer distances only to a small extent and slowly.
- the drying device is a molded part containing the hygroscopic substance. It is conceivable, e.g. that the hygroscopic substance is embedded in or applied to a plastic from which then z. B. a film material can be produced, which represents the drying device there after insertion or insertion into the sample container.
- plastic materials which may have up to 70% of hygroscopic substance (for example molecular sieve). It is of course also conceivable to spray from such plastics drying devices with other suitable forms and then use them.
- drying device and the container in a two-stage injection molding process. It would be conceivable, e.g. with a special tool first to spray a tubular drying device and then to this form the container. In this case, the drying equipment would not be made as a separate use.

- the wall area is provided with openings which allow a gas exchange between the drying agent and the sample, but particularly preferably prevent a passage of the usually particulate drying agent.
- the containers according to the invention are tubes.
- One conceivable insert could therefore be in the form of a cylindrical sleeve with a smaller diameter compared to the tube, at the upper end (viewed with respect to the inlet opening of the tube) of a circumferential collar having an outer diameter corresponding to the inner diameter of the tube is. The collar would then prevent desiccant from escaping up into the tube. Reference is also made to FIG. 1.
- the wall area of the insert is, as mentioned, provided with openings, which have special properties. This may be problematic in manufacturing if the insert is a plastic part.
- a further embodiment of the invention therefore provides that the wall region of the insert is provided with any breakthroughs, wherein additionally, a, the wall region inside or outside covering device is provided, which produces the special permeability properties.
- the device may, for. B. be a kind of fine-pored coating that is pulled from the outside over the wall portion of the insert or alternatively attached to the inside.
- the pore size is preferably chosen so that it allows the gas exchange between the drying agent and the sample, but prevents the penetration of desiccant particles to the sample space.
- the manufacture of the container according to the invention in the embodiment just discussed is as follows: First, the particulate desiccant is poured into the tube. Then the optionally provided with said coating insert is inserted into the tube, but not yet moved to its final position. In a next step, the tube is then turned upside down, after which the desiccant is distributed in the outer compartment defined by the insert. Then the insert is advanced to its final position.
- Further embodiments of the invention therefore provide drying devices that can be provided outside the tube with desiccant and then used in total in the tube.
- a particularly preferred embodiment provides that the drying agent to a solid, z. B. sleeve-shaped drying device is formed, which can be used without further inserts, etc. in the container. It is conceivable to compress the drying agent, to sinter or to extrude.
- the drying agent is embedded in a plastic from which then z.
- a Foiienmaterial can be produced, which can be used as a drying device in the container or inserted. It is of course also conceivable to spray from such plastics drying equipment with other suitable forms as a film and then use them.
- the drying device is a device which has a bottom region, an outer circumferential wall region and an inner circumferential wall region. Analogous to the above-discussed use is characterized between the a compartment for the drying agent and through the inner wall area a compartment for receiving the sample defined inner and outer wall area. The outer compartment is then filled with the desiccant and sealed at the top. The device can then be inserted into the container. It is understood that the inner wall region in turn has the required breakthroughs for the desired gas exchange between sample material and desiccant. Of course, the above-mentioned coating or a corresponding lining of the inner wall can also be provided here. The preparation of a container according to the invention with the last-mentioned device is compared to the embodiment with the use easier to manufacture, it being ensured in this solution that the drying agent has its maximum surface and thus its maximum drying activity.
- the invention not only relates to a container for holding laboratory samples, but also to the use of a device for obtaining samples.
- a sampling device for this purpose, which has a holding rod extending from a stopper, the cross section of which tapers towards its free end so that an edge results and in this end region is provided with a staining which receives the sample material , Furthermore, it can be provided that the rod has a shorter length than the devices usually used for sampling. Alternatively or additionally, it can also be provided that the rod and the flocking are designed to be relatively rigid, so that also the winning, or breaking up of dried samples is possible.
