Embodiment Construction

[0047] Figure 1-14 Each shows a glued needle syringe 1 . The syringe 1 is of the prefilled type and extends along the longitudinal axis X1. The syringe comprises a syringe body 2, generally made of glass, which is generally tubular and centered on the axis X1. This body 2 comprises a nose 8 into which a hollow needle 10 is pushed. The needle 10 is fixed to the inside of the nose 8 by gluing. The nose 8 has an outer recess 80 . The needle 10 comprises a beveled distal portion 10.1. The syringe body 2 contains an active ingredient P, such as a drug. The syringe 1 also comprises a standard rod 4 , the end of which is equipped with a seal 6 . The seal 6 acts as a piston to inject the active ingredient P through the hollow needle 10, and the seal 6 is therefore often referred to as "piston" or "piston seal". The seal 6 is affixed to said rod 4 , ie it is connected in translation with the rod 4 in both directions of movement. More specifically, the rod 4 is screwed inside t...

Abstract

The invention relates to a method for producing pre-filled cemented needle syringes, comprising the steps of: fitting a device (D) for protecting the needle onto syringe bodies (2), the device comprising an external sleeve which can move along a longitudinal axis between a forward position in which it covers the needle, and a retracted position in which it does not cover the needle, means for returning the sleeve to the forward position, and a needle protector; arranging the syringe bodies (2), which are provided with the protective device, in recesses (O204) provided in a holder (200); placing the holder (200) in a container (100) for transport; removing the holder from the container; filling each syringe body with an active principle; inserting a plunger into each syringe; and removing the syringes (1) from their holder for the purpose of inspection and labelling.

Description

technical field [0001] The invention relates to a needle protection device for protecting needles and a glued needle type syringe comprising the needle protection device. Background technique [0002] It is known that a needle-protecting device, which may be known under the name of an "after-use safety device", acts to protect the needle of the syringe at the end of the injection. This avoids needle injury when removing the needle from the patient's body and prevents the spread of diseases such as VIH. [0003] For example, GB-A-2 114 006 discloses an injection gun for animals. The gun is designed to be reused on multiple animals. It consists of a sleeve surrounding the needle, the sleeve comprising two telescoping tubes. A spring holds the inner tube in position over the needle. The cap protects the needle. The cap comprises two parts enclosing the joint filled with the sterile liquid and a detachable part arranged so that it can be detached from the rest of the cap by...
