Needle for a syringe, syringe and corresponding control system

Abstract

The invention discloses a needle (1) for a syringe, including a tip (2) at one end (3) of the needle, adapted to penetrate a body tissue during usage of the syringe, and a hub (4) at the other end (5)of the needle, to attach the needle to the syringe. A pressure sensor (6) is in the needle; means (7) are provided to transmit outside the needle a pressure value sensed by the pressure sensor (6) inthe needle.

Description

technical field [0001] The invention relates to a needle for a syringe. [0002] The present invention also relates to an injector, and more particularly, to an injector and a control system adapted to, when a liquid is injected through the injector into or near body tissue or body fluids not suitable for the liquid, Alert the user. Background technique [0003] Injecting fluids such as steroids, local anesthetics, hyaluronic acid, etc. into tissues, organs or body cavities is very common in everyday medical practice. [0004] When administering an injection, it is important to determine the proper location for injecting fluid. In the vast majority of cases, these injections are performed by a blind technique, i.e. according to external anatomical landmarks, or under ultrasound, fluoroscopic or CT guidance. In many cases, however, these imaging techniques provide insufficient definition to confirm the exact location of the needle tip without a doubt. [0005] Even for ex...

Problems solved by technology

[0019] This device allows some degree of control over the injection pressure, but has a number of issues that prevent it from being the ultimate solution to the problems mentioned above

[0020] First, it creates some ergonomic problems: many operators are disturbed by the presence of the tube connecting the syringe and needle to the device, and the presence of the device itself, which changes the more streamlined system of syringe-injection lines-needle usual structure

[0024] Finally, existing devices do not provide any information about lower-than-expected injection pressures, which may be associated with important complications of local anesthesia, namely intravascular or inadvertent spinal injections of local anesthesia

[0025] It also does not document the possibility of injection pressure being created during the procedure and therefore does not constitute evidence of good clinical practice at the time of litigation
