Abstract

Improved safety syringe, of the type used by medical personnel, for single use, consisting of a cylindrical body (2) with a blunt elliptical ring (1) on its upper part and a frustoconical mouth on the lower part (3) where the needle is coupled, with a piston or internal rod also cylindrical and hollow (6) with a conical mouth (4) extended in a ring (5) with tabs and ending with a piece like inverted mushroom (9) with a gummy piston (10), said syringe being essentially characterized in that the inner cylinder (6) has two appendages or support plates (7) in its lower part.

Description

Improved safety syringe.

Field of the Invention

This invention is related to the material auxiliary medicine, specifically with syringes disposable safety, to avoid accidental punctures and accidental in the health professions.

Object of the invention

The first rule, the most efficient, the best of all rules to avoid an accidental prick, is to cancel or isolate the needle used as soon as possible, since every second that passes considerably increases the danger of accidental contagion and avoid this is possible by depositing it inside the stem cylindrical and hollow.

It is the case, that in many countries Underdeveloped is traded with used syringes. Many researchers have studied this problem by finding different solutions, being one of them to get the break of the fragile nerve integrated in the stem, whereby the Syringe is rendered useless.

Background of the invention

In the relatively recent past it they made glass syringes, which were sterilized boiling them with their plunger and needle, to destroy the germs; then it was found that certain organisms resisted this treatment

Currently the trend in the models of syringes that are used are required of the following features:

TO)

Avoid the risk of punctures, by cancellation of the used needle, according to various procedures

B)

Than are for single use in order to avoid contagion infectious

C)

That to the above adds the ease and security for its elimination as hazardous waste.

D)

Than Safety and single-use syringes are the simplest  Possible in handling.

The present syringe model tries adapt to the characteristics cited.

The present invention is a further development. of the concept shown in Utility Model U200402366, with the modification of the cylindrical and hollow rod; on the other hand we get the plunger autoblock in the same syringe elastic or piston with a torsion movement of the rod or rod, completely rendering it useless.

Description of the invention

The syringe model has the devices simple and safe to achieve the objectives for which this designed:

one)

Achieve the annulment of the needle of a simple and safe way.

2)

Get the syringe from a only use.

To get the annulment of the needle of a quickly and safely, the embolus or stem has been modified, in Three parts, which we describe below:

TO)

He cone trunk or funnel, which is designed to facilitate the needle entry, driven there by the index and the thumb,

B)

He triangular eyelash ring, located at the base or narrow part of the funnel, which allows the entry of the needle with sum ease, not allowing its exit, acting as a valve.

C)

In the prolongation of the triangular tooth ring we have the cylinder gap that will allow us to retain, guard and completely isolate the used needle

At the bottom we have a thin and fragile nerve that allows, all reciprocating movements of the piston or embolism inside the syringe, two small appendages or inserts They allow the elastic piston to not bend.

The fragile nerve with a pressure movement and torsion is broken by separating the piston rod, leaving unused syringe.

More elaborate description of the drawings

Figure one

The needle and the cap are easily seen that accompanies any syringe in its manufacture and packaging.

Figure 2

We have the syringe body that consists of a cylinder, which has in its upper part (1) a ring elliptical blunt that facilitates, the operation of injecting the medication In the injection.

The cylindrical part (2) on which it is printed a volumetric scale, which allows you to measure the volume of prescribed liquid medication.

At the bottom we have a shape conical trunk (3), where the head of the needle, with slight pressure.

Figure 3

We classify in four parts (from top to bottom in the figure) for a better understanding: funnel or cone trunk (4), which in its lower part has a ring (5) of eyelashes triangular, extending from the eyelash ring we have the body (6) cylindrical and hollow that allows to house and retain the needle Infected without possibility of exit. In its lower part we have the mechanism that will allow us with a pressure movement and torsion break the fragile nerve (8) which has been helped in their  reciprocating movements by two small plates (7), by way of Crutches, to avoid twisting the fragile nerve in a moment uncontrolled

The fragile nerve (8) joins the lower part of the cylinder (6) with the base of the mushroom inverted (9) which adjusts with the elastic piston (10).

Figure 4

We fear completely assembled our syringe, with all its elements, and discard the cap as Packaging item that we don't need at all.

When the needle has accomplished its mission (already used) we take it by the head (the thickest part) gently, with the index and thumb fingers and we introduce it inside the cylinder through funnel and triangular eyelash ring acting as a valve that allows entry but not the needle outlet.

Figure 5

The needle is inside the stem cylindrical, canceled its possibility of puncturing. Our next step is to completely disable the operation of our syringe and for this, according to the figure, we see that with a torsion movement we break (8) the fragile nerve, leaving release the top and locked the piston, so that this loses the reciprocating movement, characteristic of the piston, remaining The syringe is completely unused.

Claims (4)

1. Improved safety syringe, of the type used by medical personnel, for single use, consisting of a cylindrical body (2) with a blunt elliptical ring (1) at its top and a conical trunk at the bottom (3) where the needle is coupled, with a piston or inner rod also cylindrical and hollow (6) with a conical mouth (4) extended in a ring (5) with eyelashes and ending with a piece as an inverted mushroom (9) with a rubbery piston (10), said syringe essentially being characterized in that the inner cylinder (6) has two appendages or support plates (7) in its lower part. 2. Improved safety syringe according to the preceding claim, characterized essentially in that it has a fragile rib (8) attached by one end to the base or lower part of said inner cylinder (6). 3. Improved safety syringe according to the preceding claims, characterized essentially in that said fragile rib (8) joins the lower part of the inner cylinder (6) with the base of the inverted mushroom (9) which in turn is assembled with the piston rubber elastic (10), forming a united body. 4. Improved safety syringe according to the preceding claims, characterized essentially in that said fragile nerve (8) is capable of breaking and breaking when performing a torsion movement, the syringe being rendered useless.
