Definitions
- New needle for medical device and device comprising the same
- the present invention relates to a new needle for medical device and device comprising it.
- a syringe needle or for any other device intended for injecting a liquid product into a human or animal body, must have a certain number of qualities: in particular it must have a very tapered free end in order to allow a quick, precise and as painless as possible.
- One of the aims of the present invention is therefore to provide a needle for medical use, the tapered end of which presents, after use, no risk of puncture for medical personnel.
- Another object of this invention is to provide such a needle with a cost price as low as possible and competitive.
- a further object of the invention is to provide a medical device which is equipped with such a needle.
- this tapered tip is made of an inert material soluble in body fluids, such as a sugar, a salt or the like.
- the present invention also relates to a medical device, such as a syringe or a transfusion device for example, which comprises a needle as defined above.
- a medical device such as a syringe or a transfusion device for example, which comprises a needle as defined above.
- a needle for medical use according to the present invention comprises a body generally made of metal such as aluminum and is provided with a channel in its axis to allow the passage of the liquid to be injected. Its free end, or distal end since the most distant from the device on which the needle is mounted, is provided according to the present invention with a tapered end.
- This tapered tip is made of an inert material, that is to say which reacts neither with the liquids to be injected nor with the constituents of the human and / or animal body, and is very quickly soluble in body fluids.
- a tip can it be made of a sugar, a salt or any other similar product, which withstands sterilization temperatures: this needle, like all medical equipment, must be sterilized before use.
- the known manufacturing methods are implemented but the taper step is omitted: therefore the distal end of the needle has a rounded tip presenting no risk to the personnel .
- the needle with rounded end is dipped vertically, the rounded end therefore being directed downward, in a hot solution of inert material: during the ascent, the drop of inert material which is retained, conforms in a sharp point during its solidification.
- the tapered tip plays exactly the same role as a tapered end of a needle, but dissolves very quickly in body fluids of such so that the needle channel is open at this end to allow the injection of a substance.
