Abstract: Endoprosthesis, in particular a hip joint prosthesis, provided with a hollow shaft being implantable in a hollow space of a bone, being of a tubular and curved shape and diminishing with respect to its diameter and material cross-cut, whereby, from the end that is near to the joint towards the end that is far away from the joint, the bending rigidity of the shaft diminishes to a relatively larger extent than the longitudinal rigidity of the shaft.

Abstract: A three-layer laminated material is particularly useful for surgical drape reinforcing panels. The material has a first outer layer of liquid impervious material, an intermediate layer of absorbent material, and a second outer layer of plastic webbing. The webbing layer, which is on top when a drape covers a recumbent person, reduces linting from the absorbent layer without substantially reducing absorbency. The webbing layer is secured to the absorbent layer by a cold cure adhesive. In preferred embodiments, one or both of the outer layers are corona-treated materials and the intermediate layer is a nonwoven fabric.

Abstract: A soft, bulky light weight fabric having good absorbency and suitable for use as a wound dressing is prepared from a hydroentangled nonwoven fabric comprising a plurality of parallel spaced apart ribs interconnected by loose fiber bundles extending between adjacent ribs. The ribs comprise high density, highly entangled masses of fibers and contain at least about 60 percent by weight of the fiber in the fabric. The fabric is napped in a direction perpendicular to the ribs to obtain the soft, bulky fabric without tearing or disrupting the integrity of the fabric.

Abstract: A system for long term releasing of medication in the mouth, and especially an intra-oral fluoride releasing system (IFRS) for releasing fluoride over a long term for inhibiting the formation of caries in the teeth. The system uses a holder for retaining and protecting intra-oral fluoride tablets or other intra-oral medicament in the form of fluoride releasing devices (IFRD). The holder has a plate with retaining sides and retaining posts or a carrier. The tablet will fit within the holder. The tablet may be located in the carrier, or ligature bands can be tied around the tablet in order to releasably hold the IFRD within the holder. The system causes a level of fluoride to be maintained over a long term within the mouth which has been found chemically effective for caries control and without causing severe irritation to oral tissues.

Abstract: Oxidized cellulose material is neutralized, by contacting an acidic oxidized cellulose material with a water and alcohol solution of a basic salt of a weak organic acid, e.g. sodium acetate, to elevate the pH of the cellulosic material to between 5 and 8. The resulting neutralized product is storage stable and has therapeutic applications, including hemostasis and adhesion prevention. Furthermore, the neutralized product may be impregnated with acid-sensitive hemostatic agents, such as thrombin, to enhance its hemostatic properties, or with acid-sensitive adhesion-preventive agents, such as t-PA, to enhace its adhesion-prevention properties.

Abstract: A surgical eye cover for ophthalmological operations includes a first plastic film (10) to be applied to the face of a patient. The film has a window (11) cut in it to permit access to the patient's eye. A second, plastic film covers the window on the side away from the face. The second plastic film is made up of two cover flaps. Each flap is attached along one edge, generally parallel to each other, with the opposite, free edges directed toward each other, so that they overlap (20) over the window. The cover provides enhanced protection from contamination of the surgical site during eye surgery.

Abstract: An orthodontic bracket is made from crystalline alumina, preferably crystalline alpha-alumina. The bracket comprises a base member for attaching to a tooth and a body member extending from the base member. The body member includes walls that define an archwire groove. The walls comprise crystalline alumina. The bracket has sufficient strength to withstand normal torquing forces imparted by an archwire.

Abstract: A locking holder is disclosed which describes a pair of flanges separated by a transverse arm. The flanges are adapted to receive a syringe placed on either side of the arm. One of the flanges contains a channel. This channel is adapted to enclose the gripping ears on the syringe. Generally, the ears lock into the channel by rotating roughly a quarter-turn when placed in the channel.

Abstract: The present invention relates to a feeding-bottle device with an adjustable air inflow, comprising a feeding bottle, a teat and a ring clamping the teat onto the feeding bottle. The teat has an annular collar intended to be retained between the rim of the feeding bottle and a flange of a clamping ring screwed onto the feeding bottle. The collar bears on the rim by means of ribs betwen them delimiting air-inlet passages. Opposite a localized annular zone of the rim, each rib has an interruption arranged in correspondence with a moulding for the bearing of the flange on the collar. Thus, by screwing the clamping ring into the feeding bottle to a greater or lesser extent, the effective cross-section of the air-inlet passages can be adjusted, deforming the collar as a result of a lever effect exerted between the moulding and the ribs, especially until the air inlet passages are closed. Leaks of the liquid contained in the feeding bottle when the child stops sucking can thus be prevented.

Abstract: The present invention provides surgical gowns and other garments possessing the advantages of raglan sleeve construction in terms of comfort and freedom of movement, with improved manufacturing efficiency. The garment of the present inveniton provides a raglan sleeve divided into an upper portion and lower portion joined approximately in the area of the bicep. Waste is greatly reduced by creating a shoulder portion from material removed to form the arm openings in the body portion of the garment. The shoulder portion is attached to the body portion of the garment to form a raglan shoulder portion which extends to about the bicep of the wearer. A sheet of material is cut in a trapezoidal pattern to form a plurality of lower sleeve portions, each of which is attached to a shoulder portion. Gowns made in accordance with the present invention exhibit the flow and shoulder lines of a raglan sleeve construction while making efficient use of the fabric from which the gown is constructed.

Abstract: A flexible spray tip device is provides so that the user may bend and rigidly hold a spray tip at the end of a syringe. Alternately, the spray tip may be rotated around 360.degree., to provide orientation and angulation of the device while simultaneously attached to the syringe.

Abstract: Garments are constructed from two identical sleeve sections folded and joined to form an upper portion, which has a neck opening and sleeves, joined to a rectangular lower portion, which forms the body portion of the garment. The upper portion and the lower portion are joined together by a straight circumferential seam. The sleeve sections and the lateral edges of the lower portion are joined by a straight vertical seam. Preferably, the sleeve sections are folded so as to be overlapped and form a neck opening that is V-shaped. In a most preferred embodiment, the garment of the present invention is a scrub shirt. The present invention makes use of sleeve sections that are in the shape of quadrilateral sections with an arcuate portion cut therefrom. The patterns disclosed make efficient use of the material from which they are cut and require only straight seams when assembled. The present invention also discloses methods of constructing garments, such as scrub shirts, in accordance with the disclosed design.

Abstract: A process for releasing leachable substances from a polymeric contact lens blank. the contact lens is confined in a cavity within a carrier to permit the hydration of the lens without permitting it to invert or roll over. A fluid flow is introduced into the cavity about the lens to extract leachable material from the lens. The process significantly reduces the amount of leaching fluid that is used and the amount of time that is needed for hydration, washing and extraction.
