A DISPOSABLE FOOT COVERING COMPRISING A PAIR OF SUPERIMPOSED LAYERS OF FILM OR SHEET MATERIAL MARGINALLY SEALED TOGETHER, THE UPPER OF SUCH LAYERS BEING FORMED OF A HIGH ELONGATION ELASTOMER FILM AND BEING PROVIDED WITH A SMALL BUT GREATLY EXPANDABLE OPENING FOR THE INSERTION OF A WEARER''S FOOT. A FUSED MARGINAL BEAD ABOUT THE OPENING PREVETS TEARING AS THE MATERIAL ABOUT THE OPENING IS STRETCHED. BREATHABILITY OF THE COVER, WHERE NECESSARY, IS INSURED BY FORMING THE COVER''S LOWER LAYER FROM A POROUS MOISTURE-RESISTANT FILM OR SHEET.

A pad for post-surgical use in dressing the incision to collect fluids exuded from it includes a relatively thick central core layer of soft, highly absorbent material. The application side or covering of the pad includes superposed layers of tear-resistant scrim or grid material and a layer of polyethylene. The outer side or covering includes a moisture barrier layer. The application and outer coverings are preferably bonded together along at least two peripheral edges.

A method of sterile packaging which involves the steps of partially filling a container with any of a number of antibacterial agents in liquid or semi-liquid form which contain iodine as the active ingredient, then sealing the container so that the air space is formed above the liquid within the container, and finally heating the container and its contents (which may include a solid object to be sterilized immersed or partially immersed in the liquid) to a temperature substantially below the boiling point of the liquid, and at a pressure of about one atmosphere, until the interior surfaces of the container above and below the liquid level, and the entire contents of such containers, are sterilized.

A culture package having a pair of separable panels defining two compartments, one holding a sterile absorbent swab and the other supporting a rupturable container for a liquid organismsustaining medium. At least one of the panels is transparent and flexible, permitting the swab to be viewed in its compartment and allowing the container to be ruptured by finger pressure so that the liquid therein may drain into the adjoining swab compartment. A sheath of distinctive color is removably fitted on the swab handle. By gripping only the sheath, a user may withdraw the swab and later return and reseal it within its compartment without contaminating the swab handle. In one form of the invention, the package includes a third slide-containing compartment oriented with respect to the swab compartment, and to the package as a whole, so that a surface of the slide is exposed when the package is opened for swab removal. The disclosure includes a description of structure for facilitating the extraction of the swab and slide from their compartments, for supporting the slide to protect it from breakage during mailing and handling of the package, and for insuring that liquid released from the rupturable container will enter and remain in the swab compartment.

A METHOD OF STERILE PACKAGING WHICH INVOLVES THE STEPS OF PARTIALLY FILING A CONTAINER WITH ANY OF A NUMBER OF ANTI-BACTERIAL AGENTS IN LIQUID OR SEMI-LIQUID FORM, THEN SEALING THE CONTAINER SO THAT AN AIR SPACE IS FORMED ABOVE THE LIQUID WITHIN THE CONTAINER, AND FINALLY EATING TE CONTAINER AND ITS CONTENTS (WHICH MAY INCLUDE A SOLID OBJECT TO BE STERILIZED IMMERSED OR PARTIALLY IMMERSED IN THE LIQUID) TO A TEMPERATURE SUBSTANTIALLY BELOW THE BOILING OF THE LIQUID, AND AT A PRESSURE OF ABOUT ONE ATMOSPHERE, UNTIL THE INTERIOR SURFACES OF THE CONTAINER ABOVE AND BELOW THE LIQUID LEVEL, AND THE ENTIRE CONTENTS OF SUCH CONTAINER, ARE STERILIZED.
摘要:
A QUANTITY OF SOLUTION HAVING A KNOWN CONCENTRATION OF ONE OF A GROUP OF ANTISEPTIC AGENTS IS SEALED TOGETHER WITH THE ARTICLE TO BE STERILIZED IN A FLEXIBLE, AIR-TIGHT CONTAINER, AND THEN THE ARTICLE AND CONTAINER ARE WORKED SO THAT THE ANTISEPTIC SOLUTION SATURATES THE EXPOSED SURFACES OF THE ARTICLE AND CONTACTS THE ENTIRE INTERIOR SURFACE OF THE CONTAINER. THE ENTIRE PACKAGE IS THEN HEATED
TO A TEMPERATURE IN THE RANGE 120*F. TO 212*F. FOR A PERIOD OF THREE TO TWENTY-FOUR HOURS, DEPENDING ON THE AGENT USE, AND SUFFICIENT TO KILL ALL BACTERIA, FUNGI, AND SPORES IN THE PACKAGE.
摘要:
A device for filtering liquids such as blood and other body fluids to separate the fluid and particulate components thereof and to confine the particulate content. An open-ended inner tube is provided at its lower end with an integral flexible lip which slidably and sealingly engages the inside surface of an outer tube containing the liquid to be filtered. Within the inner tube''s lower end is a retainer sleeve having a flow passage extending axially therethrough. A filter membrane extends over one end of the sleeve and also between opposing side walls of the sleeve and inner tube to perform the dual functions of filtering fluid flowing through the passage as the inner tube is urged into the liquid-containing outer tube, and of forming a sealing gasket for securing the sleeve and membrane in place within the inner tube. A stop shoulder limits the extent to which the sleeve and membrane may be forced axially into the inner tube.

A disposable pad for controlling body temperature at selected areas of application includes a flexible fluid conduit for passage of source fluids, whether hot or cold, and a soft, absorbent, flexible covering with a surface which will neither stick nor slide when applied, for example, to an open wound. The absorbent covering may act either as an applicator of medicaments in combination with the conduit for temperature control, or it may be wetted with a sterile fluid to enhance the heat transfer relation between the conduit and area of application, or it may act as an absorbent bandage or dressing or as a surgical sponge.
摘要:
A sterile packaging method which involves the steps of sealing a suitable fluid or solid product within a container capable of withstanding prolonged exposure to temperatures up to 212* F., and thereafter heating the container and its contents for an extended period, but at a temperature substantially below the boiling point of water, until the container''s interior surfaces and contents are sterilized.
