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 ca

Embodiment Construction

[0013] refer to figure 1 , figure 2 and 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 accordin...

Abstract

The invention relates to a screwing assembly used for screwing a closing plug (2) onto the open thread end (6) of each injector (3). The screwing assembly is provided with a concave portion (31), a supporting device (29) of each injector (3), and an actuating device (35), wherein the concave portion (31) is used for receiving one closing plug (2) from a hopper (9), and the hopper contains a plurality of closing plugs (2); the actuating device (35) is used for enabling the concave portion (31) and the supporting device (29) to move relative to each other around and along the longitudinal axis (4) of each injector (3) by means of rotor transition movement, and therefore each closing plug (2) is screwed to the open end (6) of the corresponding injector (3).

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 ...
