Description

The invention relates to medical equipment, and more specifically, to single-use syringe ampoules used for storage, transportation, injection of medical immunobiological preparations and other drugs. capable of providing sterility and aseptic conditions during injection.

The purpose of the invention is the provision of sterility during injection and preservation of the properties of the drug by improving the reliability of sealing the cylinder.

In FIG. 1 shows the proposed syringe ampoule in package A; in FIG. 2 syringe ampoule collected for injection B; in FIG. 3 - node I in FIG. 1.

The syringe ampoule in the package includes a process cylinder (CT), an injection needle in a case (IF), a pusher (T).

The technological cylinder contains preparation P, cylinder 1 with finger rests 2, elastic element 3, piston 4 with flanging a and with threaded sleeve 5, plug 6, with removable pin b and cap

7.

The needle in the case contains the following elements: a protective casing 8 with a mandrin 9, an injection needle 10 with a housing 11, a protective casing 12.

Assembling a process cylinder (CT) is as follows:

a piston 4 is inserted into cylinder 1, a flanging is bent, and on the outer surface of cylinder 1 and rolled up with a plug 6 with a removable check (b): cylinder 1 is filled with a preparation;

the elastic element 3 is inserted and rolled up with a removable cap 7.

Filling with the drug cylinder 1 can occur in a different sequence, namely with the final operation of filling the drug.

In this case, the cylinder 1 is assembled with the piston 4, the plug 6 and the elastic element 3, and the filling occurs by puncture with a feeding needle,

1819624 A1 piston, which provides reliable sealing of the internal cavity of the technological cylinder.

This system of puncture of an elastic 5 element with a piercing mandrel (TROAKAR method) eliminates the penetration of the material of the elastic element into the inner cavity of the needle.

Thick-walled elastic element 3 allows you to fill the inner cavity of the technological cylinder by means of a feeding needle, creating a sterility of the filling process.

Claims (1)

Claim A single-use syringe-ampoule containing a cylindrical housing for storing the drug, a piston with a pusher, an elastic element that covers the cylinder and the injection needle, characterized in that, in order to ensure sterility during injection and preserve the properties of the drug due to reliable sealing of the cylinder, the syringe piston The ampoules are equipped with an annular flange fixed on the outer surface of the cylinder. pa and the injection needle is equipped with a sharp mandrin and is made according to the trocar system. connected to the vacuum and drug line. The filling cycle can be carried out according to the scheme: creating a vacuum in the cylinder; vacuum cut-off; supply of the drug to the inner cavity of the technological cylinder. The preparation of the syringe ampoule for the injection takes place in the following order: 10 by means of a check (b) the plug 6 is removed; pusher T is screwed into the threaded sleeve 5: the protective cap 7 is removed; 15 the protective cover 12 is removed; body. 11 is put on the cylindrical part of the container body (c) (in this case, the needle 10 with a piercing mandraine 9 pierces the elastic element 3 and enters the preparation 20 P); · Flanging (a) is reclined, taking up position (e); the protective cover 8 is screwed together with the mandrel 9 The syringe ampoule is ready for injection. With sharp temperature fluctuations in the proposed scheme there is no movement!
