摘要:
A device and a method for disinfecting a microtome cryostat with introduction of a disinfection agent (3) into the cryostat chamber (2), action of the disinfection agent on the cryostat chamber, removal of the disinfection agent (3) by precipitation in a colder area (6) and drainage away from there. To enable such a microtome cryostat (1) to be disinfected several times per day without prolonged interruption of operation, a disinfection agent is used (3) that is effective below below 0° C. and is introduced as a mist into the cryostat chamber (2) at below 0° C., the disinfection agent (3) being effective as a hair-frost-like deposit in the cryostat chamber, wherein the hair-frost-like deposit is displaced into a colder area (6) by sublimation and is converted to liquid by sporadic defrosting phases of this area (6) and thus removed.

A knife holder for a microtome has a plate arranged pivotably on its base member, which, in its functional position, covers the cutting edge of the knife and is spaced apart from the cutting plane towards the side of the knife holder remote from the specimen. The plate is also spaced apart from the knife holder on the side of the cutting edge of the knife. The plate precludes gripping of the cutting edge of the knife and a pivoting mechanism for the plate is coupled to a switch. When the plate is pivoted out of the functional position, the motor drive of the cutting movement is locked, or a brake precludes any movement of the knife slide or specimen slide. The plate preferably consists of a transparent material to permit observation of section removal in the functional position.

The invention relates to a method and device for the cross-referencing of identification (1) of tissue slice supports (2), for microtomised analytical samples still to be mounted thereon, with identification information (3) of a tissue sample holder (4) of a tissue sample (5) which is not yet microtomised. The conventional problem of cross-referencing is improved in a simple manner, whereby the identification information (3) for the tissue sample holder (4) is automatically detected when positioned in the microtome (6) and an identification (1) corresponding thereto is automatically transferred to at least one tissue slice support (2) and that tissue slice support (2), provided with the identification (1), is dispensed for application of the tissue sample slice at the moment when a tissue sample slice must be applied to a tissue slice support (2).

A method for disinfecting a microtome cryostat (1) comprises a defrosting phase (11), provision (13) of a vaporous disinfection agent (2) which acts upon the closed cryostat chamber (3) and a period of time (14) during which said disinfection agent (2) acts, and having an associated device for carrying out the method. According to the invention, fast and effective disinfection and rapid restarting of a microtome cryostat (1) is possible with secure drying, the temperature difference (ΔT1, ΔT2) being produced after the period of time (14) in the cryostat chamber (3) whereupon the precipitated disinfection agent (2) is removed (18) to a cold area.

The invention relates to an apparatus for handling microtomized tissue samples (1) which are arranged on an object carrier (2) and are provided with a machine-readable code (3), with a reader (4) serving to detect the information of the code (3) and a controller (5) serving to convert the information for handling purposes. In order to use such an apparatus to classify unsorted object carriers (2) with respect to one another in a patient-oriented manner for evaluation purposes, it is proposed that a transfer apparatus (6) and at least one drive (7) are provided, which are formed in such a way that they can pick up object carriers (2) from a supply device (8) and move them to a presentation carrier (9) which has receptacles (10) for a plurality of object carriers (2), an apparatus (11) which is ready to hold presentation carriers (9) being arranged and formed in such a way that it keeps a large number of presentation carriers (9) ready in a manner such that they are accessible to the transfer apparatus (6), wherein the controller (5) is formed in such a way that it controls the at least one drive (7) on the basis of the information of the code (3) of the object carrier (2) to the effect that object carriers (2) which originate from a patient can be moved by the transfer apparatus (6) to at least one presentation carrier (9) in an order which is assigned to the patient.
摘要:
A microtome has a blade holder on which a blade is mounted, an anti-roll device for supporting a section preparation that has been produced by means of the blade, and a suction device by means of which the section preparation can be picked up by suction and carried off. The suction device has a nozzle, with an adjustably mounted nozzle body, and a suction channel. Provision is made that the anti-roll device is mounted on the nozzle body and is adjustable, in particular pivotable, together therewith.

The invention relates to a unit for the treatment of histological samples. The unit comprises a treatment chamber (1), a device (2) for supplying and removing treatment agents (3, 3′, 3″) to and from the treatment chamber (1), and a control system (4) for the performance of the treatment. The aim of the invention is to develop the unit in such a way that the need to carry out different treatments is taken into account in an economical manner. Towards this end, at least one other treatment chamber (5) is provided, by means of which treatments can be carried out independently from the first treatment chamber (1), the device (2) and the control system (4) also co-operating with that other treatment chamber (5).
