Abstract: A sample tube for injection molded with two cores in one base with an intermediate bottom forming a well for receiving the biological material. In a second stage, the bottom edge of the cylindrical wall is heated and turned inwardly to form preferably a rounded bottom of complementary contour to a stamp applied thereagainst in a thermal reforming operation.

Abstract: A device for carrying out a test for the detection of particles in urine, especially for carrying out a test to determine the susceptibility of a test subject for kidney stones, whereby urine from the test subject is taken and collected and then the detection test is carried out, whereby the urine after a stand time is poured out of the test vessel, whereby the residue of test particles may be present in the test vessel is detected subsequently by the addition of a detection reagent, especially a dye reagent for optical detection, especially for a self test by a test subject, for example, at home. The device having a collecting vessel in which the urine is directly collected from the test subject and which also simultaneously forms the test vessel. The test vessel is column shaped and tapered toward its bottom and upwardly transitions into an overflow region.

Abstract: A blood collection device has a holder having a forwardly extending sharp-edged cannula capable of venipuncture and a rearwardly extending cannula. A guide sleeve into which a blood-collection tube is insertable from one end, at an opposite end, threadedly receives the holder whereby the tube can be filled with blood conducted by the rearwardly extending cannula into the device. A closed end elastic tubular valve rubber sheath surrounding and hugging the rearwardly extending cannula is shape locked and force fitted in said guide sleeve.

Abstract: A blood extraction device has a holder with a hollow needle cannula anchored therein. A rear end portion of this cannula is surrounded by a closed-end elastic hose like valve rubber tube with an air gap between the tube and the cannula. With a minimum of effort and cost a reliable anchorage of the valve rubber tube in the holder is obtained by pressing a clamping member within the holder against the exterior of the valve rubber tube and thereby plastically deforming this clamping member.

Abstract: A blood sedimentation device has a transparent small-diameter sedimentation tube and is provided with a calibration mark a short distance below its upper end. The column of blood is introduced into the sedimentation tube and is precisely bounded at the lower end of the tube. The device has a displacement sleeve surrounding the lower part of the sedimentation tube in an airtight manner allowing movement by sliding, and further has a tubular receptacle, closed at the bottom, surrounding the displacement sleeve in an airtight manner allowing movement by sliding, this receptacle accomodates the blood sample.
