Disclosed is an injection device including: —a needle support; —an injection needle integral with the needle support and having a free end arranged away from the needle support; and —a needle extraction mechanism including a base connected to the needle support and a plunger movable relative to the base between a needle use position and a needle extraction position. The base is movable relative to the needle support between an inactive position of the extraction mechanism and an active position of the extraction mechanism. The plunger includes an outer member and an inner member, movable relative to the outer member, from a retracted plunger configuration to a deployed plunger configuration wherein the plunger length is greater than in the retracted configuration.

Injection device with extraction mechanism and associated process

The present invention relates to a treatment kit comprising:

Treatment kit, associated measuring device and associated preparation method

Medical port

The invention relates to a system for injecting a liquid into a body, comprising an implantable chamber disposed under the skin and an injection device including: a base bearing an injection needle having a free end that is intended to be inserted into the chamber; an injection conduit connected to the needle; means for extracting the needle; means that can be actuated to generate excess pressure in the injection conduit; synchronization means between the extraction means and the generation means for actuating the generation means during a needle extraction phase. The synchronization means can essentially only actuate the generation means when the free end of the needle is located in the chamber during the needle extraction phase.

System for injecting a liquid into a body, such as that of a patient

The invention relates to a device () for injecting a liquid into a body, in particular that of a patient, of the type that comprises: a base () bearing an injection needle () that is to be inserted into the body; an injection conduit () connected to the needle (); means () for extracting the needle () from the patient, including a plunger () mounted such that it can slide in relation to the base () between a needle () use position and a needle () extraction position; and means () for generating excess pressure in the injection conduit () as the needle () is extracted, including a flexible section () formed in the injection conduit (), a cam surface () rigidly connected to the plunger (), and a supporting surface rigidly connected to the base (), in order to compress said flexible section () between the cam surface () and the supporting surface radially and perpendicularly to the needle () as the plunger () slides towards the needle () extraction position. The invention is characterized in that it includes means () for retaining the flexible section () substantially perpendicular to the needle ().

Device for injecting a liquid into a body of a patient

An injection device comprises: a needle support; an injection needle which is fixedly joined to the needle support and which has a free end which is arranged with spacing from the needle support; and a mechanism for extracting the injection needle, comprising a base and a pushing member which can be moved relative to the base between a position in which the needle is used and a position in which the needle is extracted. The base is permanently connected to the needle support and can be moved relative to the needle support between an inactive position of the extraction mechanism and an active position of the extraction mechanism.
