Description

Infuser

The present invention is a means for disinfecting a needle when it is inserted into a tube, a bottle or any other object capable of carrying a liquid. This is to prevent said needle from contaminating or bringing unwanted elements inside the container or liquid conveyor objects, whether sterile or not.

Normal infusion systems consist of a catheter inserted into the patient's body. This catheter is connected to a tube equipped with a connector, itself connected to another tube which will be attached to the container of the infusion liquid.

The tubing carrying the infusion fluids. Are usually connected to each other by simple fitting (i.e., a tube fitting into a fitting, itself connected to another tube, this fitting is possible by ends similar in shape, but one of which is of smaller size and constitute the male and the other female elements).

This system is not proof against the risk of infection. Indeed, germs and microbes are frequently deposited on the outer edges of the tubing and on the fittings, which means that when a tubing fitted with its male fitting is separated from its female fitting to allow another tubing with fitting to be connected to it because connected to a container of liquid to be administered to patients. Microbes can get inside the fitting and are trapped when the new tubing is fitted with its fitting. It is from this moment that germs develop inside the connection and are transported directly into the patient's body by the infusion fluid, thus causing very serious or even fatal infections.

The present invention makes it possible to remedy these drawbacks.

The invention relates to a needle disinfection device characterized in that it comprises in its lower part an interchangeable disinfection means intended to be pierced entirely by a liquid conveying needle itself fixed to an upper part (A) .
