21~0~03 PLIABLE SECURITY PROTECTOR, FOR
SYRINGE NEEDLES IN GENERAL
The present invention is related to needles for hypodermic syringes, and particularly it refers to a pliable security protector, for syringe needles in general; having as an aim to bring forward a practical and secure means destined to the covering of said needles.
As it is already known, in the handling of syringes (for the o application of injections, blood extraction, etc.), the needles constitute the paramount risk factor, as it is a cutting and stabbing means, which can be easily introduced in the body due to its size and shape, even through involuntary actions.
The problem deepens even more when the needle has been already used as, in case of accidental pinching or cutting, if it was contaminated -for example as a consequence of having been used byo a person with hepatitis, AIDS, etc.), the wound produced in second terms constitutes the best way for the transmission of the illness through blood.
Removable tip protectors are known, these are destined to cover the needle against accidents, when it is handled before or after having been used.
Although it is true that said tip protectors comply their objective of covering the needle, given that they are fit simply through pressure, it is common that they uncouple -due to incorrect collocation, defectuous fitting, or simply as a - 21S0~03 consequence of the handling they are submitted to- which, through time, has caused numerous accidents.
The invention object of this patent consists on a pliable protector, which is normally found in a position of complete 5 covering of the needle, while as it is folded, said needle is easily enabled; being enough the removing of the locking means to cause its automatic coverage due to the own elasticity of the articulations.
Said device has the advantage of forming a single piece o with the coupling base of the needle; in such a way that there is no possibility that the coverage might loosen or get lost, at the same time it does not require to fit in or enter in contact with the needle for its command, since the same is done with one hand, with no risk whatever for the operator.
Finally, it must be noted that the new covering device does not imply the modification of the shape nor the size of the conventional coupling nozzles of the syringe, neither the type or size of the needle.
The acceptance that this invention will have when put into 20 practice can be easily imagined, whichever the category or destination it is given, as, due to the characteristics that define it, it can be applied to any type of needle and usable in any type of syringe.

In general terms, the security protector (b), for syringe needles (2), is of the type consisting of a long tip protector which, surpassing the length of the needle (2), it covers it completely; having said needle its beginning in a nozzle (a) coupled to the syringe (not illustrated), while at the opposite part it ends with a sharp pointed end (2').
More particularly, and as can be seen in the Figures, the long tip protector (b), consists of four elementary arms (3), (4), (5) and (6), respectively, with an internal complementary concavity and articulated between each other two by two, that compose two composed arms (3-4) and (5-6) constituting a deformable parallelogram.
Thus, the first elementary arm (3) and the third elementary arm (5), that reciprocally vinculate through one intermediate articulation (5') form -as it was said- a first composed arm (3-5) that, through an articulation (5"), they connect to the body (8) of a head (c), while at the opposite part, by means of another base articulation (3') it connects with the body (1) of the nozzle (a), figure 3.
At the same time, the second elementary arm (4) and the fourth elementary arm (6), that reciprocally vinculate through an intermediate articulation (6') form -as it was mentioned- a first composed arm (4-6) that, through an articulation (6"), they connect to the body (8') of a head (c), while at the opposite part, by means of another base articulation (4') it connects with the 5 body (l) of the nozzle (a), figure 3.
In the tubular head (c), the semi-nozzles (9) and (9') form an opening destined to enable the passage of the needle (2), figures 2 and 3.
This header has the salients (7) and (7') as holders, while lO the other salients in the areas of the intermediate articulations (5') and (6'), form or can form other intermediate holders.
To assemble the device around the needle (2) -in the manufacturing phase- the header (c) is formed by two parts that have respective nerves (lO) and (lO') which can be leant opposite 15 against each other, which have coupling means male-female that bind them, such as perforations of ones, and the others with rounded salients (lO") across them (figures 3 to 5).
Likewise, from the internal part of the parallelogram, the intermediate articulations (5') and (6') have internally projected 20 centering fins (12) and (13) that can present a format as can be observed in figures 4 and 5, and especially in the section of the figure 6; defining a narrow passage of the needle (2) between them.
Lastly, the protector possesses means of positional locking 25 of the arms, be it in the position folded towards the base (a) -figure 3- held back in the same through a simple pressure that produces the wedging of these locking means (rounded salient and perforations, hookings or simply the end (1') of the body (1) in the header (c). In the passage (11), these locking means can be given by a salient or membrane (11') which positionally fixes 5 the folding and unfolding of (b), by a forced adjustment against the lateral external parameters of the needle (2).
The head, (c) as well as the arms (b) and the coupling nozzle (a), can be, preferably, structured as a single piece of plastic material or an appropriate similar one; or constituting at o the end of the arms (3) and (4) articulated in (3') and (4') with a ring the adheres to the body (1) of the coupling nozzle (a). This last way of embodiment, obviously, has the advantage of being able to adapt the system of the conventional needles, with no need of modifying or producing them expressly.
Each needle (2), provided with its incorporated protector (b), can be sold in a package including a security binding (p) (figure 1), that guarantees that the system has not been previously used (figure 1).
Having been removed said binding (p), in order to enable 20 the needle (2), it is only needed to press the protector at the holders (14) and (14'), as it is shown in figure 2, with which the composed arms (3-5) and (4-6), articulated in (5')-(6'), (3')-(4') and (5")-(6"), will fold its structure deforming the parallelogram in such a way that the arms (5) and (6) get near the arms (3) and 25 (4), respectively (figure 3), and, at the same time due to that folding, the needle (2) projects out of the protector, being 2150~03 enabled for its normal use, and fixed in such position due to the locking means.
Once the needle (2) is used, the protector (b) is pressed again in the opposite way to the one indicated in figure 2 5 (figures 10 and 11), with which the parallelogram will close and will cover the needle (2) completely (figures 7 and 9). To cooperate with this procedure, the structure (b) can be normally tensed in an elastic way towards the folding position.
There is no doubt that when the present invention is put 10 into practice, same can suffer modifications respecting certain details in its construction and shape, which does not imply that it is getting apart from the fundamental principles clearly substantiated in the following claims:

Having been removed said binding (p), in order to enable 20 the needle (2), it is only needed to press the protector at the holders (14) and (14'), as it is shown in figure 2, with which the composed arms (3-5) and (4-6), articulated in (5')-(6'), (3')-(4') and (5")-(6"), will fold its structure deforming the parallelogram in such a way that the arms (5) and (6) get near the arms (3) and 25 (4), respectively (figure 3), and, at the same time due to that folding, the needle (2) projects out of the protector, being 2150~03 enabled for its normal use, and fixed in such position due to the locking means.
Once the needle (2) is used, the protector (b) is pressed again in the opposite way to the one indicated in figure 2 5 (figures 10 and 11), with which the parallelogram will close and will cover the needle (2) completely (figures 7 and 9). To cooperate with this procedure, the structure (b) can be normally tensed in an elastic way towards the folding position.
There is no doubt that when the present invention is put 10 into practice, same can suffer modifications respecting certain details in its construction and shape, which does not imply that it is getting apart from the fundamental principles clearly substantiated in the following claims:
