Abstract: A safety needle cap for a syringe completely covers the hypodermic needle during non-use or between injections. The needle can be easily exposed with a reduced danger of accidental needle-stick injury. The needle cap can be unlocked from the closed position by being rotated, and then slid backwards onto the syringe barrel by a defined travel distance. Several settings, up to the full extension of the needle, are possible. After use, the needle retracted into the cap, once more preventing needle-stick injury.

Abstract: A non-toxic mucosal disinfectant for topical application in the nose has a composition of 91% isopropyl alcohol of at least 50% by weight; sesame oil not exceeding 45% by weight, lemon oil of about 2% by weight, aloe of about 5-10% by weight, and optional components of chlorhexidine gluconate and grapefruit seed extract. All of the components are mixed homogeneously, with the sesame oil supplementing and neutralizing the dehydrating effect of the alcohol.
