Problems solved by technology

[0005] Because the closure is usually snap-locked on the open end of the syringe, machines of the above-mentioned kind known for the compounding of pharmaceutical products have some disadvantages, which mainly stem from the fact that the closure and the syringe cost a relatively high The coupling forces move against each other, which can cause damage to both the hermetic closure and the open end of the containment barrel, preventing subsequent assembly of a new needle
[0006] Furthermore, machines of the above-mentioned kind known for the compounding of pharmaceutical products do not allow the use of threaded closures and therefore have a relatively low flexibility of use

Embodiment Construction

[0013] refer to figure 1 , figure 2 with image 3 , reference numeral 1 generally represents a screw assembly for screwing a substantially quadrilateral closure stopper 2 onto a known type of syringe 3, each screw assembly having a given longitudinal axis 4 and comprising a housing cylinder 5, the housing cylinder is set There is an externally threaded open end 6 and is slidingly engaged by a plunger 7 .

[0014] In the context of the present subject matter, the stopper 2 is designed to be absolutely tamperproof during handling of the syringe 3 containing the pharmaceutical product to be administered to the patient.

[0015] The screwing assembly 1 comprises a box-shaped frame 8 closed at the top by a receiving hopper 9 for a plurality of plugs 2 arranged in the hopper 9 with the concave side of the plugs facing upwards.

[0016] The hopper 9 comprises a vibrating plate 10 (of substantially rectangular shape), delimiting a support surface P for the bung 2, inclined accordi...

Abstract

The invention relates to a screw assembly for screwing a closure (2) onto a threaded open end (6) of a syringe (3), said screw assembly being provided with a recess (31) adapted to receive a Closing plug (2) of the hopper (9) containing a plurality of sealing plugs (2) therein; support means (29) of the injector (3); and actuating means (35) for switching with the rotor The movement moves the recess (31) and the support means (29) relative to each other around and along the longitudinal axis (4) of the syringe (3), thereby screwing the closure stopper (2) onto the open end of the syringe (3) itself ( 6) on.

Description

technical field [0001] The invention relates to a screwing assembly for screwing a closing plug onto a syringe. Background technique [0002] In the preparation of injectable pharmaceutical products, it is known to manufacture a machine comprising: at least one reservoir for a plurality of containers (bags, syringes and bottles in the case relevant to the subject); a dosing station for the dispensing of drug products obtained by feeding drug products from bottles and diluents from bags into syringes; and holding and conveying devices for transferring containers between reservoirs and Transfer between dosing stations. [0003] The syringe comprises a containment cylinder, a plunger slidingly engaged in the containment cylinder, and a needle snap-locked onto the open end of the containment cylinder itself. [0004] After the drug product has been dispensed in the syringe, the needle is removed from the syringe and the open end is sealed with a sealing plug, allowing medical ...
