Problems solved by technology

[0011] Also, it can happen that during the time between the delivery of the drug delivery device to the user and the connection of the connector to it, the collar, for example, by contact with some product that drips excessively from the end piece when the user finishes cleaning fall) and somehow degenerate
In this case, the connection formed between the connector and the collar is not secure and may break when the connector is connected, during use, or when the connector is disconnected from the delivery device after use

Embodiment Construction

[0037] refer to figure 1 and 2 , which shows a drug delivery device 1 of the present invention, which will be used to deliver a product (not shown) to a patient. Thus, the drug delivery device 1 will be engaged with a connector (not shown), such as an IV (intravenous) connector, which typically allows the drug delivery device, containing the product to be delivered, to be coupled to an IV line, which itself Direct connection to the patient's vein.

[0038] refer to figure 1 , a drug delivery device 1 comprising a reservoir 2 for delivering a product to be delivered, eg a drug, to a patient. Reservoir 2 may be any container, such as a vial, catheter or syringe barrel. The reservoir 2 has a distal end 3 and a proximal end 4: when the reservoir is a syringe barrel, the proximal end 4 is usually open. The distal end 3 of the reservoir 2 comprises a longitudinal axis A (see figure 2 ) end piece 5 : this end piece 5 has the general shape of a tube and is penetrated by a chann...

Abstract

The present invention relates to a drug delivery device (1) defining a reservoir (2) for containing a product, having a distal end (3) comprising an end-piece (5) defining a channel (6) for the transfer of the product from the reservoir, said drug delivery device comprising means for coupling said end- piece (5) with a connector, said coupling means comprising a collar (7) defined around a portion of the end-piece (5) and extending from the distal end (3), said coupling means comprising connection means (10; 20) connectable to said collar (7), said connection means (10, 20) comprising a tubular wall portion having an interface (17) defined thereon for engagement with an internal face (7a) of said collar, and a retaining hook (13) having engagement means (15) engageable with at least part of an external face (7b) of said collar (7) when said connection means (10) is connected to said collar (7).

Description

technical field [0001] The present invention relates to a drug delivery device having an end piece surrounded by a collar and dedicated engagement means for engaging said end piece with a connector. Background technique [0002] Drug delivery devices generally comprise a hollow body forming a reservoir for containing a drug. Furthermore, the distal end of the body forming the reservoir usually comprises an end piece in which an axial channel is arranged, through which said drug is expelled from the reservoir. [0003] In this application, the distal end of a component or device must be understood to mean the end furthest from the user's hand, and the proximal end must be understood to mean the end closest to the user's hand. [0004] Furthermore, the reservoir and the end piece of the drug delivery device may be manufactured from various materials, such as glass or plastic. When it is known that the stability of the product stored in the reservoir will not be affected by t...
