Abstract

The invention relates to a plastic syringe for injections and blood sampling, of which the needle cannula, which is fixed on the plunger, remains within its barrel both before and after use, said barrel being a useful sheath and providing ideal protection. The needle cannula comes out and, after use, returns inside the barrel of the syringe where it is locked by suitable protrusions or by internal locking rings within the barrel of the syringe. The invention is intended to prevent accidental jabs and the drawing of blood which can often lead to serious infections illnesses such as tetanus, AIDS and viral hepatitis.

Description

SYRINGE DISPOSABLE

It is the invention of a disposable syringe of plastic material for good pitting and blood samples has prevent accidental punctures and the effusion of blood, comprising a needle cannula which is inserted the head of the piston remains, both before and after use, and protected content in his body (cylinder) where, at the time of use, the operator makes out and, after use, the fact return through indirect movements exerted on the î-aton of the piston and thereafter the blocks at corpts syringe to prevent accidental release.

The disposable syringe for injections so far known, is the body-comptose syringe (cylinder) of the piston with a small gum and needle cannula which is directly graft outside the cone tightness placed at the tip of the syringe Corpis (cylinder); in this syringe, protecting the lubricated cannula (needle) is entrusted bya plastic material cap on which the operator must necessarily act to stir before use and delivered after use; during these times, the well Operators often touches, with his hands, the lubricated cannula (needle), or in the remaining, in turn, polluted

and often suffered accidental punctures that may be the cause of serious infectious diseases contagion, such as: tetanus, hepatitis A virus, AIDS. Sometimes also hold true accidental punctures even among strangers sanitary operators that fall piar random on employees and bags or lubricated cannula (needle) lost his precarious case or resuite not protected from appropiée way.

The goal, which proposes this invention is to eliminate all the above analyzes disadvantages.

The invention, as it is. in the description and in the claims, avoiding all the above disadvantages and also solve the problem of creating a syringe where the needle cannula grafted to the piston finds its most toilet papers case and more valid protection and has perfect within the same syringe body (cylinder), both before and after use, at the time of use, it delivers it to its holster (body-syringe) and fixed to the inside of the sealing body syringe cone the means of movement exercised by the operator on the rod of the piston; after use, it is removed the needle cannula of the sealing cone and removes the means of movement exercised piar the operator on the rod of the piston and at the end on the blocks to prevent accidental spilling; so doing, the operator's hands are far removed from the lubricated cannula

(Needle) and therefore it joins to avoid in a safe way the risk of accidental contacts and hermit crabs. The advantages obtained through this invention consist essentially in the fact that the aiguillecanule located both before qu'apires use his case more hygienic and more valuable protection and a perfect inside the syringe body (cylinder) where do pieut pias out to accidental causes; further aiguillecanule can never be polluted or polluting or causing accidental punctures; in the end, by virtue of its particular characteristics of security interest, the syringe used outside of hospitals may be placed in containers for mixed waste at the disposal resulting nonexistent danger of punctures and souillements ace identelles.

Complessivement, the syringe is also characterized by the extreme simplicity of its operation and the modest cost of implementation.

The invention presents a way piluε detail later with designs that also are examples of execution.

Figures 1 and Ia represent according to the invention of different ways of embodiment of the syringe.

Figures 2,3,4,5 show the syringe during the various stages of its operation.

In Figure 1 is shown a first example of implementation of the idea which resuite corpsseringue composed by (A), the needle cannula (B) and the piston (C). In the body-syringe (A) the sealing cone of the needle cannula (1) is characterized because it is closed by an elastic material membrane (2) which can perforate is made, exit and return the lubricated cannula (needle), respectively, at the time and after use; this membrane allows prfaite tightness during the suction stroke and inoculation liquid and- at the same time, avoids the bloodless; Syringe body further is characterized by the presence in its interior, any device, such as a thread (Ibis), propire to ensure the blocking of the keg a'uille of the cannula; the syringe body is further characterized by the presence of two lateral projections which are symmetrical and can move (3), they not only constitute bearing superfices the fingers of the operator but also they are pushed after use within the syringe body, for locking the piston, and with it the needle cannula.

The Aguil the cannula (B) is composed as follows: lubricated cannula (4) painless triple thread, inserted and welded to the center of the keg which is characterized by the presence of any device, for example thread (5) which enables a safe way, inside of the sealing cone (Ibis) place sommet- body-syringe; the keg is further characterized by its graft inking (S) has the recess of the piston (8), with fins and fesεures or breakthrough for pemettre inoculation of the whole quantity of liquid contained in the syringe body. The plunger (C) is characterized by a recess (80 at the center of its top provided with stops and bypassed by an eraser (7) pierced in the center, right to receive the keg inking graft (6) and in promoting évissement and unscrewing is inside the sealing cone (Ibis) is further characterized by the presence of lines "affaibl issememt (10) to facilitate breakage after use, and by . presence of a niche (3) right to receive and trap the locking projections (3) the figure Ibis shows a second example of advantageous embodiment of the idea: in this case, the cone of etanchéité (1) place at the top of the syringe-body (a) is opened in front for the passage beyond lubricated cannula (needle) and, in place of the membrane that can puncture, this has the exeterieur any device, exeple a thread (2) forthe closure with a protective cap (D) that can disconnect, avoids the bloodless. a in its TER AL, the sealing cone (1) for accuellir the keg, is characterized by a device for example a teraudage (2a), good sour keg closure predisposes required; Syringe body (A) in this. example, is characterized by rings indoor seats (3) in a projection of the other elements which constitute the stops and locking the piston and with it the needle cannula.

The needle cannula (b) consists of the lubricated cannula (needle) (4) painless triple afilage inserted into the center of the keg which is characterized by the presence of a teraudage (5) for attaching to the sealing cone

(2a) of the body-syringe; the keg is still characterized puor the graft anchor the piston (6) with different vanes and key to evissement with fessures or punctured to inoculate the entire quantity of the liquid.

The plunger (C) is characterized by a recess (8) at the center of its top provided with stops and bypassed to exesterieur by the eraser (7) pierced in the center, right to receive the keg graft anchor . (6) and in promoting evissement. and unscrewing the sealing cone (2a) of the body-syringe (A); is further characterized for the presence of weakening lines (10) facilitating its rupture after use leaving the traps in the syringe body-end portion (9) of the piston and needle cannula assembles a him. The assembly and movement mode of operation time, anyway, are very simple and easy. The syringe is assembled for sterilization, with the needle cannula graft atop the pi ston (f ig 2.) Is placed al INTER IOR of corpsseringue that shows the container and at the same time, the protector; at the time of use, the mere push forward the piston rod brought out the lubricated cannula (needle), while a movement of rotation in the direction of 11th Aigui a watch causes évisemment the keg has the inside the sealing cone of the body-syringe suitably prepared (fig.3); after aspiration and inoculation of the liquid, the keg is εe graft automatically to the piston and a simple movement in the movement opposite to that of the clockwise causes the disconnection of the needle cannula thus can be removed (fig.4) is inside the body or syringe is blocked (fig.5); at this point, for a major and higher safety, it is broken stick piston along the weakening lines and the whole can be stored also in containers for mixed waste, being non-existent pollution and the danger of accidental punctures.
