Abstract: An adhesive-backed strip is stuck onto a patient's skin. The strip has an opening provided through it at the site where a blood sample is to be taken. On its outer side, the strip is provided with an upstanding annular collar surrounding the opening through the strip, thereby providing a sump bottomed by the surface of the subject's skin. The sump receives a plug of liquid-absorptive material. As the subject's skin is pierced by a cannula, inserted down through the sump, to take a blood sample, the initial exudate, including capillary blood and other tissue fluids, exudes into the sump where it is absorbed by the plug. Thereafter, venous blood is conventionally drawn into the cannula while the bandage remains in place.

Abstract: An external urinary drainage means in the form of a condom which at the outer end thereof terminates in or is connected to a length of hose for carrying off the urine. The condom is formed as a short condom which covers only the head (glans) of the penis. Extending from the outer end of the condom or from the length of hose is a sheathing body which, when the condom surrounds the head of the penis and the foreskin has been drawn forward over the condom, can be made to encase the condom and foreskin, thereby providing a labyrinth seal. At the inner edge of the condom, a recessed section can be provided to accomodate the neck of the penis at the corona. The sheathing body is tightly connected to the outer end of the condom or to the length of hose, preferably such that a space is formed between the length of hose, the condom and the sheathing body.

Abstract: A method to facilitate the analysis of uncoagulated blood, for example freshly drawn blood or heparin blood, wherein the blood is filled into a test tube of plastic and a porous, elastic body in which one or more ballast element optionally are embedded, is placed in the upper layer of the blood and the blood is centrifuged such that the body in friction contact with the inner surface of the test tube is pressed through the blood, wherein the body or bodies are of glass or another suitable material with a surface whose characteristics correspond to those of glass, and where in addition there is used an overlying layer of small beads or other particles whose specific gravity is adapted in such a way that the beads after the centrifugation are embedded in the fibrin layer as reinforcement, and further wherein the two features may be combined by utilzing only the described small beads. A means for carrying out the method is also described.

Abstract: A urination device for bedridden female patients, in the form of a funnel-shaped device adapted to be placed against and at least partially around the vulva.

Abstract: Uncoagulated blood is separated into components by placing the blood in a glass test tube, placing a porous, elastic body in the upper layer of the blood, and centrifuging such that the porous body in friction contact with the inner surface of the test tube is pressed down through the blood so as to form above the body a layer of serum overlying a layer of red cells which overlies the body.
