DESCRIPTION:

BRIEF SUMMARY
FIELD OF THE INVENTION

This invention relates to medical equipment and, more particularly, to devices for the safe delivery of drugs to the human body by syringes, and to the combination of such syringes and carrying cases therefor. This invention also relates to devices for the safe removal of bodily fluids from the human body.


BACKGROUND OF THE INVENTION

There is a significant risk of cross infection associated with reusable syringes. If not properly sterilised, used syringes can contain a reflux of infected bodily fluids. This risk exists both for reusable syringes which are used to inject drugs and those which are used to remove bodily fluids, such as blood. An accidental needle prick can result in infected blood being injected into the body of a person, possibly resulting in the transferral of a disease.
Many of the drugs used to treat humans, for example, drugs used to treat impotence in human males, are temperature sensitive and need to be kept at a cool temperature. However, those drugs need to be self administered, and are preferably able to be carried on the person of the user. Thus, a need exists for a convenient and safe way of storing, carrying and administering temperature sensitive drugs. Similarly, a need exists for a safe way of storing, carrying and administering a wide range of drugs which are in prescribed fixed doses for self administration, and which may or may not be temperature sensitive.


SUMMARY OF THE INVENTION

There is disclosed herein a single use syringe comprising: and section is adapted to be attached to said container section.
Preferably, said syringe further comprises locking means adapted to prevent the separation of said container section from said valve section after said container section has been connected to said valve section.
There is further disclosed herein a single use syringe in combination with packaging, said packaging comprising: cover portion, said cover portion sealed onto said backing portion around its periphery, said container section being securely housed between said backing and said cover portions; wherein a part of said first section can be torn away to expose a base part of said container section; cover portion, said cover portion sealed onto said backing portion around its periphery, said needle section being securely housed between said backing and said cover portions; wherein weakened portion adapted so that a part of said second section may be torn away to expose a receiver part of said needle section.
There is further disclosed herein a single use syringe in combination with a carry case, said carry case comprising: base forming a space therebetween to house one or more said syringes; retain a cooled temperature for a predetermined period of time.
