Abstract: The invention relates to a cannula, preferably equipped with a cannula holder for, in particular a blood sampling device, which comprises a pivotable protective housing (102) for a free end of the cannula. Said protective housing (102) is closed on the periphery except for a cannula insertion opening (8) provided between opposing side walls. Said insertion opening is produced by at least one pair of lamella (8a, 8b), formed on the side walls, the lamella tapering towards one another in the manner of a funnel and forming an expandable funnel slot. The protective housing (102) comprises two housing parts which can be inserted into each other. The inner housing (2a) comprises the pair of lamella (8a, 8b) and an outer housing (11), which surrounds the inner housing (2a), is embodied as a sleeve that is less elastic than the inner housing (2a).

Abstract: A butterfly-needle set has an elongated two-part case forming a pair of transversely open slots. An elongated needle in the case has a pair of generally coplanar and oppositely projecting wings projecting out of the case through the slots. The slots are sufficiently long that the needle can move longitudinally between a front position with the needle projecting from a front end of the case and a rear position with the needle completely within the case. An elastically deflectable spring element projects at a small acute angle toward a rear end of the case into at least one of the slots so as to deflect elastically and allow the needle to move from the front position into the rear position and to block movement of the needle from the rear position into the front position.

Abstract: A blood-drawing device has a specimen tube having a projecting tip having an outer connection region of a predetermined diameter and a guide sleeve fittable over the tip and having an inner resilient part. The inner resilient part has an inside diameter smaller than the diameter of the connection region. A needle fitted to the guide sleeve is surrounded by an elastomeric tubular needle shield inward from the guide sleeve. The sleeve can move between an outer position with the needle shield extending inward past the inner needle end and the resilient part offset outward from the connection region and an inner position with the needle end in the specimen tube, the needle shield compressed between the sleeve and the specimen tube, and the resilient part fitting tightly around the connection region and deformed outwardly thereby such that the resilient part grips the connection region.

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 long-term urine-collection kit has a large-capacity can having a wide mouth, a small-capacity cup having a rim dimensioned to sit in the mouth, and a removable cover fittable over the mouth of the can when the cup is sitting in the mouth. The capacity of the can is enough, e.g. 2-3 l, to hold a day's urine, and the capacity of the cup is enough, e.g. 400-500 ml, to hold a single urination.

Abstract: A box for shipping bottles has a rectangular floor, generally parallel sides projecting from longitudinal edges of the floor, parallel ends projecting from end edges of the floor and bridging the sides, and a cover fittable over the sides and ends and forming therewith and with the floor a generally closed space. Holders set in a row are each hinged on the floor in the space and are each shiftable transversely toward and away from each of the sides to define bottle-holding spaces with the ends. The holders are of generally identical section but of different longitudinal length. Each holder has a pair of parallel legs having lower edges hinged on the floor and upper edges and a top panel bridging the respective upper edges and hinged thereon. One leg of each pair of legs is substantially shorter than the other leg to impart to the holders a right-trapezoidal shape.

Abstract: A blood collection device has a holder having a forwardly extending sharp-edged cannula capable of venipuncture and a rearwardly extending cannula.

Abstract: A tube holding a sample of blood and having an end provided with a pierceable closure is partially evacuated of gas by an apparatus that has a stationary guide defining an axis inclined at an angle to the horizontal. A needle fixed in the guide projects axially downward therein. A slide in the guide forms a downwardly inclined and open seat centered on the axis and adapted to receive the end of the tube. The slide is movable in the guide between an outer position with the seat spaced past an end of the needle and an inner use position with the needle projecting into the seat so that in the use position the needle projects through the closure of the tube fitted to the seat. The slide is urged axially downward in the guide, and a pump is provided for aspirating air through the needle.

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 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-collection apparatus has a needle having a sharp front end and a sharp rear end, a mounting collar on the needle between its ends and a holder tube extending along an axis and having front and rear ends. A piston axially slidable in the holder tube is provided with a mount adapted to fit complementarily with the mounting collar with the needle rear end directed axially back in the tube. The piston normally is at the tube front end with its mount projecting axially forward from the tube. A flexible strand has a front end attached to the piston and a rear end projecting from the tube rear end. This mount is fitted into the needle's collar after the blood-collection operation is complete so that a pull on the strand retracts the piston back into the tube carrying the needle fitted to its mount.

Abstract: A filter is pressed down in a collection tube holding separated blood as a lower solids mass and an upper liquid mass defining with the lower mass an interface. The filter has a sleeve fittable in the tube and having a lower end covered by a membrane that fits snugly in the tube. A vertical level of an upper surface of the upper liquid mass in the tube is detected and a pusher is engaged with an upper end of the sleeve to push the filter downward in the tube. Downward pushing of the filter is stopped when the upper end of the sleeve is at a predetermined spacing above the vertical level of the liquid upper surface. A vertical level of the interface is also detected and downward pushing of the filter is also stopped when the membrane is at the vertical level of the interface. Thus two separate events can trigger stopping of the downward pushing: reaching the interface or reaching a certain fill level in the sleeve.

Abstract: A sample vessel (1) for taking very small amounts of blood, consisting of an outer vessel (2) and an inner vessel (3) which can be inserted into it, which is closed at the bottom, and on top, on the side where the sample is deposited, is configured with an open, very thin-walled blood sample ring (7) which can be closed by a stopper (4) and which protrudes in situ from the outer vessel (2). The outer vessel (2) has a collar (5) which supports the inner vessel (3) below the blood sample ring (7), and which is suitable for holding in centrifuges. The sample vessel makes taking blood samples easier, is simpler to produce and offers a greater variety of possibilities for use.

Abstract: A cap for a blood-sampling tube has a collar adapted to fit on the tube and a tubular extension extending from the cap, defining an axis and having an outer end remote from the cap. An annular wall is formed inside the cap spaced from the outer end and an annular lip projects axially backward from the outer end and has an outer surface spaced radially inward of an inner surface of the extension and an axially directed inner end. A pierceable flat membrane in the extension on the annular wall snugly engages the inner surface of the extension and has an outer face spaced axially from the inner end of the lip. The lip has an inner surface defining a cylindrical passage of a predetermined diameter and the wall has an inner edge defining a similarly dimensioned coaxial annular passage.

Abstract: A molding apparatus has a fixed mold part having a pair of flat side faces and formed on each face with a plurality of laterally open half cavities and respective movable mold parts each having a side face juxtaposed with a respective fixed-part side face and displaceable transversely into and out of a molding position with the movable-part side face flatly engaging the respective fixed-part side face of the stationary mold part. Each movable mold part is formed with a plurality of half cavities forming full mold cavities with the half cavities of the respective fixed-part side face in the molding position. Each movable-part half cavity is formed with at least two inwardly open pockets, one of the pockets of each movable-part half cavity being open at the respective movable-part side face and being transversely closed by the respective fixed-part side face.

Abstract: For the removal of a small amount of fluid, in particular blood, from a sealed container, and the deposition of a drop of fluid on a slide by a dropper, and the subsequent spreading of the drop, the rear end of a dropper needle having a longitudinal channel which passes therethrough is pressed through a seal into a container. Once the needle is inserted into the container, a drop of fluid moves out of the container via the longitudinal channel to a slide. After depositing the drop of fluid on the slide, the dropper itself is used to spread and distribute the drop of fluid on the slide, so that spreading of the drop of fluid is facilitated and hazardous waste is reduced to a minimum. The dropper used for this purpose is made integral with a spreader.
