A resealable vial featuring a connector assembly having a membrane and a pusher for selectively opening or sealing the fluid passageway between the bottle and the connector end of a luer hub. The connector assembly includes a body disposed on said bottle, and means for communicating fluid such as a luer connector hub which may be separately provided with the body or formed integrally therewith. The luer connector hub features a connector end open for access by medical delivery instrument, and an opposed end which is disposed for fluid communication with a recess defined by the body. The body defines a recess having a fluid path with the open top of the bottle. A membrane, preferably formed from an elastomeric material, is secured across both the recess and the open top of the bottle, and may be retained between the top surface of the bottle and the body. The membrane preferably includes a central area sealing the recess from the open top of the bottle, with one or more fluid openings defined on a portion of the membrane outside of the central area. A pusher is located in the recess. A force exerted on the pusher deflects the membrane towards the interior of the vial, urging the membrane and fluid openings away from the body to open the fluid path between the bottle and the recess. The pusher may be structured to include one or more fluid pathways so as to facilitate fluid flow through the recess. A sealing rib may be provided around the portion of the periphery of the recess to enhance sealing contact between the central area of the membrane and the recess.

A coordinated cutting and spreading mechanism within a syringe dilator sub-assembly is applied to an eye surface during an intravitreal injection to provide an access window free of the conjunctival layer and through which an injection needle can be inserted. The system and method comprises a dilator sub-assembly including both the cutting and spreading mechanism and the intravitreal injection needle, for use with a conventional syringe. The dilator sub-assembly includes a number of projections to secure points of the surface of the conjunctival layer, a cutting member to incise the conjunctival layer, and at least one deflectable projection to move during the intravitreal injection, spreading the incision, and creating a window opening in the conjunctival layer through which the intravitreal injection needle then enters. Upon removal of the device from the injection site, the deflectable projection is released and the window opening in the conjunctival layer is closed.

System and methods for out-of-band pairing sterile medical device with non-sterile devices without compromising sterility thereof. A system includes a sterile medical device; a non-sterile computing device; at least one near field communication (NFC) tag; and a sterile packaging enclosing the sterile medical device. In one example, a sterile percutaneous needle guidance device needs to pair and communicate with a non-sterile computer. The sterile device has an NFC tag embedded in the sterile device and an NFC tag embedded in the sterile packaging. The two NFC tags include identification information duplicate of each other. Before opening the sterile packaging either NFC tag can be scanned with the non-sterile device to initiate wireless pairing. If the sterile package is opened before pairing, the NFC tag contained in the packaging can be brought out of the sterile field and scanned with the non-sterile computer thus preserving the sterility of the sterile device.

The adhesive bandage consists of a support with one surface having pressure sensitive adhesive and a wound covering pad placed centrally on it, which are covered by two protective detachable tear away tabs. The tear away tab consists of a single layer over the adhesive surface of the support and becomes two layered over the pad region. The two layers are fused at the zone of fusion near the margin of the pad, but are otherwise free from each other. The layer close to the pad, called inner barrier layer, completely covers the pad area. The outer layer, also called grasping layer, partially covers the barrier layer and the pad, and is folded upon itself to give sufficient length. When the outer layer is grasped to pull apart the releasable tear away tabs the inner barrier layer prevents contact of the finger to the pad. As one pulls apart the tear away tabs the barrier layers unfold and prevent contact of the fingers with the wound and wound exudates, preventing cross contamination. The bandage is enclosed in an envelope with the free ends of uneven dimension to have free part of the surface of both leaves, which are easy to grasp and separate.

The present invention provides an improved flat package of petri dishes and method of producing the same for prolonging shelf life and preservation of sterility of the petri dishes.

A pad of dispensable adhesive tape segments is shown and described. The pad includes a protective envelope and a number of tape segments. The tape segments are arrayed such that detachable pull tabs for each are exposed for grasp. The envelope may include a strip folded over onto itself and adhered in place. The envelope is pulled open and may be adhered to an environmental surface. Tape segments have adhesive of weaker adherence than the adhesive of the envelope so that when pulled by a pull tab, each tape segment preferentially releases from the next, but the envelope maintains adherence to the environmental surface. Adhesive lined tabs initially holding the envelope closed may also be used for adherence to the environmental surface. Preferably used for medical tape, the envelope is waterproof to maintain sterility of tape segments.

The field of the present invention is that of fosfomycin formulations for parenteral administration, in particular for intravenous administration. Formulations of the prior art provide fosfomycin as a powder to be diluted directly prior to the administration. The aim of the invention is to provide a fosfomycin formulation for parenteral administration which is easier to produce and administer or which lowers the risk of puncture injuries for healthcare professionals and the health risks for the patients (for example due to contamination or incorrect dosages) by preventing additional processing steps. During the course of the invention, it was surprisingly shown that fosfomycin is much more stable in an aqueous solution than what is commonly assumed. The invention therefore provides a closed container which contains an aqueous solution for parenteral administration, wherein at least one pharmaceutically acceptable salt of fosfomycin, in particular fosfomycin disodium salt, and a pharmaceutically acceptable acid, in particular succinic acid, are dissolved in the solution. Preferred containers are breakable ampoules made of plastic or glass, puncturable vials, infusion bags, or syringes ready for injection.
