Definitions
- the mvention refers to a disposable sy ⁇ nge that has been improved ⁇ n determ ⁇ nate structural aspects ith the object of achieving better performance and greater functional effectiveness than conventional sy ⁇ nges.
- the object of the invention is to obtain a disposable sy ⁇ nge of the type comp ⁇ sing a mam body which the chamber for the liquid to be m ⁇ ected ⁇ s determmed, and a needle with a coupling cone on the end of said mam body.
- the needle ⁇ s complemented by a kmd of sheath that protects and sterilises ⁇ t.
- the sy ⁇ nge mcludes peculiarities with respect to the system for coupling the cone to the mam body and coupling the protective sheath of the injection needle which, obviously, complements the assembly.
- a type of disposable syrmge made up of a cylmdrical, hollow body, which ⁇ s open at ⁇ ts rear end to allow the movement of a rod correspondmg to a pistón that moves mside said cylindrical body for pushing and / or absorbmg the liquid.
- the cylmd ⁇ cal body determines a chamber between ⁇ ts front end and the pistón that can move axially m the same.
- Said axial rod ends a ind of flattening or expansion to allow item to be manually actuated by the user.
- This type of syrmge ⁇ s complemented by the corresponding needle which ⁇ s housed ma covermg m the form of a hood or sheath that constit a means for protectmg the needle and also achieving hermetic seal g and the corresponding ste ⁇ lisation, smce the needle has a cone on ⁇ ts rear end for coupling to the corresponding end or neck established for this purpose on the front end of the mam body of the syringe.
- the rear end of the sheath meets the pe ⁇ meter of said coupling cone, thus achieving a hermetic seal and mamtammg ste ⁇ lisation of the needle, so that when the unit ⁇ s go g to be used, ⁇ t ⁇ s sufficient to couple the needle holder which slightly protrudes with respect to the rear end of the sheath over the neck of the body of the syringe, and then to extract or separate the sheath for the syringe to be ready to use.
- the coupling between the cone of the needle and the neck of the body of the syringe must be watertight to keep the liquid msulated mside the mam body of the syringe, or what amounts to the same thmg, m ⁇ ts corresponding chamber.
- the syringe of the type referred to m the foregomg section has a series of peculiarities on the basis of which the problems and drawbacks mentioned above are resolved. More specifically, the first novel characteristic of the syringe of the mvention ⁇ s that the neck provided m the front end of the mam body of the syringe, upon which the cone of the needle must be coupled, projects lengthwise with respect to the end which the front end or part of the body extends, to define a large rmg-shaped channel between said extension and the neck of the coupling.
- the front extension of the mam body of the syringe has an inner helicoidal flutmg which determines a kmd of thread for holding a rmg-shaped rim provided m the rear part of the coupling cone.
- Said sheath also mcludes a perimet ⁇ c rear ⁇ m, which stops agamst the ner, slightly trunco-comcal surface of the extension provided with the helicoidal flutmg mentioned above, as the cone fits onto a complementary corneal surface corresponding to the concentric neck of the mam body.
- the liquid to be m ⁇ ected exits, pushed by the pistón, through said neck and ⁇ s mjected by means of the needle that ⁇ s coupled m the way described above.
- Figure 1 shows an exploded view of the mam body of the syringe that ⁇ s the object of the mvention, as well as of the assembly made up of the needle with ⁇ coupling cone and the protective sheath of the same.
- Figure 2 shows a view ⁇ n longitudinal cross-section at% of the syringe assembly, when the cone of the needle ⁇ s coupled to the corresponding neck provided on the front end of the mam body of the syrmge, the sheath being m fitted position but ready for separation.
- the disposable syringe of the mvention ⁇ s made up of a mam hollow cylmd ⁇ cal body, which ⁇ s open at ⁇ ts rear end to allow the mtroduction of a pistón for pushmg the liquid to be mjected. Between said pistón and the front end of said mam body the chamber for the liquid ⁇ s established.
- Said front end of the mam body (1) has an axial concentric neck (2) with a slightly trunco-conical shape while, externally to said neck (2), the body (1) has an extension (3) that ⁇ s slightly shorter than the neck (2), a deep channel (4) bemg established between both of them.
- the wall (5) of said channel (4) converges downwards, that ⁇ s, ⁇ t defines an mverted conicality, with the peculiaria ⁇ ty that m the surface of said mverted corneal wall (5) a helicoidal fluting (6) ⁇ s provided that determines a thread for effectively hold ga cone (7) to carry the mjection needle (8).
- Said cone (8) determines the means of coupling said needle to the mam body of the syringe, with the peculiarity pity that said cone (7) has a perimetric rim or flattenmg (9) at ⁇ ts rear end which, when coupling or axial sliding on the neck oceurs, causes a threadmg on the helicoidal flutmg (6) of the inner corneal surface (5) of the axial outer wall (3) of the body (1) of the syringe, thus fittmg together the coupling cone (7) and the neck (2) of the body of the syrmge by pressure, and therefore hermetically, and thus ensurmg that the covermg established by said body of the syringe (1) ⁇ s watertight.
- this type of needle (8) with ⁇ ts coupling cone (7) are complemented by a protective sheath (10) to mamtam ste ⁇ lisation and protection of the needle ⁇ tself (8), which ⁇ s coupled externally and by f ⁇ ction to the outer surface of the coupling cone (7). Therefore the separation of releasmg of said sheath (10) is carried out once the cone (7) is coupled to the neck (2).
- the rear part, m which a flattenmg (11) of the sheath (10) ⁇ s established, ⁇ s housed m the channel (4) that determines the concentric neck (2) and the outer wall determmed by the extension (3).
