Description

The invention relates to medical equipment, in particular to injectable medical needles for single use.

Closest to the invention is the needle structure of TERUMO EUROPE, Belgium. It contains a tube with a pointed working end and an adapter. The tube is placed in a plastic cylindrical case, which is worn on part of the adapter. The needle case is additionally packed in a sterile bag. Before use, the latter is opened from the side of the tube and, without touching the adapter, put on the syringe. The sterile bag and case are discarded.

A disadvantage of the described needle design is as follows. In order to remove the medicine placed in a special vial, the pointed end of the needle (tube) has to be inserted there through a stopper, piercing it. The needle naturally becomes infected (contaminated). She is also infected after introducing it into the ampoule with the medicine, since the needles come into contact with the ampoule. Therefore, the infected needle must be thrown away, and a new needle is put on the syringe to puncture the skin of a selected human organ for drug administration, observing the requirements for disposability. This circumstance reduces the economical use of needles, complicates the procedure and increases the time spent on it.

The aim of the invention is to remedy these drawbacks, i.e. expanding the functionality of the needle.

In FIG. 1 and 2 shows a needle in section; in FIG. 3 - needle with a protective cap,

packed in a transparent sterile bag; in FIG. 4 - the same, with the torn part of the sterile package; in FIG. 5 - a needle is put on the syringe with a cap inserted with a pointed end into the medicine (the moment the medicine was removed); in FIG. 6 - a needle, put on a syringe with medicine (before piercing the patient's skin).

The needle includes a tube 1 with a pointed

the working end and the adapter 2. The protective cap 3 is put on the last 3, the working end of which tightly fits the tubular rod 1 (see Fig. 2) and is made pointed. The lateral channel 4 on the pointed part of the cap 3 coincides with the working end of the tube 1. The needle is additionally placed in a sterile bag 5 (see Fig. 3).

Before using the needle, the bag 5 is opened from the side of the adapter 2 (see Fig. 4) and, without touching the latter (but only to the bag 5), put on the syringe. After this, the package 5 is opened to the end and discarded. In a bottle of medicine (through its cork)

or the pointed end of the protective cap 3 is inserted into the ampoule, the tubular rod 1 is protected from infection. The drug can be removed from the vial or ampoule (see Fig. 5) by the message

the side channel 4 with the channel of the tube 1 of the needle. After that, the cap 3 is removed from the adapter 2 and discarded, and the skin of the selected organ of the person is pierced by the working end of the tube 1 and only after

This is thrown away, observing the principle of disposability, the needle.
