Definitions

  • the present invention belongs to the field of medical apparatuses and in particular deals with a protective kit to be applied to syringes needles and cannulas needles.
  • a syringe is generally made by a hollow barrel which contains a
  • liquid to be injected or sucked a plunger kit, mobile within said hollow barrel, which pushes or sucks the liquid, and a final part equipped with a needle connected in one extremity to the hollow barrel.
  • a cannula for medical purposes is made by an inlet for the sliding of the liquids and by a final part equipped with a needle connected to said cannula.
  • the replacing of the protective hood after the use is a mandatory procedure either for hygienic purposes either to allow the complete drainage of the syringe or cannula set, as per some regulations or, however, sanitary procedures.
  • a fir ⁇ t inconvenient is that, at the present state of the art, due to the typically cylindrical conforma ⁇ tion of small diameter of the protective hoods used, the operator's fingers operate necessarily in proximity to the entrance of the protective hood and therefore leading to a probable contact with the upper part of the needle.
  • a further inconvenient is that the centering of the entrance of the hood with the needle which has to be re-encapsulated, turns out to be very difficult and therefore not of immediate accomplishment as it requires a particular care.
  • the main purpose of the present invention is to obviate to the above-mentioned inconveniences, by carrying out a protective device for syringe or cannula needles which makes the replacing manoeuvre of a protective kit, easier and safer.
  • a second purpose is to carry out a protective device which keeps the operator's fingers away from the upper point of the syringe or cannula needle during the replacing manoeuvre of the hood after use.
  • a further purpose is to carry out a protective device which makes the centering of the hood with respect to the needle much easier.
  • Last but not least purpose of the invention is to obtain a protective device for injection needles and in particular for syringes and cannulas, by using an easy manufactu ⁇ ring process without making use of complex technologies or speciali ⁇ zed work-people.
  • a protective kit for injection needles in particular in syringes and cannulas having a hood of a preferably truncated-cone shape, with a height at least equal to the measure of the needle on which it ha ⁇ to be placed, said hood equipped with means which make the placing of said hood on said needle stable, characterized by comprising a grip handle steadily constrained to the lower base of said hood, said grip handle equipped with a handle having a free extremity and having the other extremity equipped with means of rotation pivoted in a fitting housing connected to said base, said handle being rotating in said housing within an angle of 90°, said housing presenting means of locking of the handle in a position rotated of 90°; said means, allowing a reversible locking, enable a counter- rotation to 0°.
  • the kit with the handle of the grip handle rotated to 0°, which results parallel to the vertical axis of the truncated-cone hood, presents the same position of the needle-syringe or cannula set when at rest, that is to say before and after the use; on the contrary, the kit with the handle of the grip handle rotated at 90° resulting orthogonal to the hood and to the respective needle, presents the position in which the operator manoeuvres to reach the above-mentioned aims.
  • Fig. 1 represents a global view of the set syringe-needle- protective kit at rest
  • Fig. 2 represents a global view of the set syringe- ⁇ eedle- protective kit when used
  • Fig. 3 represents an axonometric view of the protective kit according to the invention.
  • - Fig. represents a frontal view of a detail of the base of the protective kit
  • - Fig. 5 and fig. 6 represent respectively an axonometric section of a detail of the base and of the handle at rest and when used.
  • n° 1 is indicated in its wholeness an injection syringe comprising a hollow barrel indicated by 13 containing the liquids to be injected or sucked, a plunger device lfl to suck or compress the liquids towards the exit terminal 8 piping to a needle 6 to carry out injections; the exit terminal 8 engages itself as a bayonet on a corresponding tubular body 7, said body being the load bearing base of the needle 6.
  • the general referring number 2 indicates the whole protective kit of the needle 6, comprising a truncated- cone hood 3, a grip handle 9 having a handle 10, said handle having a free extremity 12 and the other extremity 24 constrained in a housing 11 connected in area 16 with the base 5 of the hood 3.
  • the hood 3 showed in the drawing, presents a heightnen slightly superior to the one of the needle 6 placed on its base 7 and linked to the hollow barrel 13 of the syringe 1; said hood, being manufactured in transparent material presents the advantage to show the presence of the inside needle, having a first major essentially truncated-cone and hollow part 18, which carries out the function of protection of the needle 6, a second cylindrical part 5 which acts as a base for the whole hood and an annular ledge
  • the cylindrical hollow from fl to 5 has a diameter slightly superior to the one of the base 7 of the needle so that by inserting said base in the lower final part 5 of the hood, a bayonet coupling is being carried out constraining steadily the set base/needle.
  • the handle 10 made by a lengthened rod with a rectangular section having a length slightly lower to the length of the hood 3, at the free extremity 12 presents a plurality of raised reedings 15 fit for allowing the hold;
  • the box-shaped body of the housing 11 can be con ⁇ titued by a capsule, opened on two sides, said capsule being pre-manufactured and subsequently welded or glued on a blind back part to the part 5 of the hood base; such varying embodiment is not showed in the drawing.
  • the handle 10 in its extremity 24 is constrained in the housing 11, such constraint being constitued by a pivoting in point 25 which allows an assumed rotation of 90°, that is to say within an angle enabled by the vertical wall of the hood 3 and the base of the housing 11 given by the wall 20; the rotation is carried out by the operator who manoeuvres by holding in hand the handle in area 15; inside the box-shaped body of the housing 11 and precisely respectively on walls 19 and 21, two almost semi-spherical raised points 22 and 23 are present, said raised points are placed upwards and towards the free edge of the walls 19 and 21; said raised points constitute the locking means which allow to the handle 10, once effectuated the maximum rotation of 90°, to keep a stable orthogonal position with respect to the hood 3 and consequently to return to the rest position and keep it, being steadily rotated to 0°.
  • Figure 5 represents the handle 10 pivoted in point 25, vertically placed parallel to wall 27 and inside the locking point 22 towards said wall 27, not being allowed to rotate if not through a rotating force carried out by the operator on the handle 10, said position is to be considered as rest position, that is to say before the use of the syringe or the cannula, and after the use;
  • figure 6 show ⁇ the handle 10 pivoted in point 25, orthogo ⁇ nally placed with re ⁇ pect to the vertical wall 27 and underneath the locking point 22, parallel to wall 20 of the hou ⁇ ing box 11, leaning on a raised base which constitutes the peak rotation point of the handle 10, which has carried out its rotation within the box formed by the inside of the housing 11, said position of the handle 10 is to be considered as the position in which the grip handle works, whereas the protective kit of the needle is being used by the operator.
  • the operator taking the set syringe or cannula provided with the needle and the protective kit according to the invention before removing said kit, he holds the grip handle, rotates of 90° the handle 10, which is being locked by the two blocking semi-spheres 22 and 23, then he makes use of it and when he wants to replace the hood - procedure which is mandatory according to the sanitary regulations and medical procedures - he is able to hood the needle with a manoeuvre which enables to keep the fingers and the whole hand away from the needle, said handle carrying out in this phase also the function of a spacer.
  • the operator has the advantage - as he can use only one hand having the other one busy with the used syringe - to make use of the handle 10 through which it is possible to better the orientation of the whole kit and make the centering of the entrance of the hood 3 with the upper part 17 of the needle 6 easier.
