Description

NAME OF THE INVENTION

BURN-NEEDLE

General explanation of the invention In daily practice, hospital and medical practice operators in general use needles or similar instruments that are initially sterilized.

Once used, these tools can become infected with bacteria of sometimes very dangerous diseases.

This device allows you not to enter more? accidental contact with a needle or a disposable instrument to the operator. The system, in practice, burns the used needle by completely removing the tip so that? can not more? be harmful. Furthermore, the power of its electrical circuit allows you to burn many needles or disposable tools in a very short time.

Explanation of the invention

The focal point of the invention consists of an electrical contact, a circuit protected by a fuse, a current transformer and another small safety circuit that blocks the machine when it, overloaded with work, gets too hot, a switch to make it inactive. .

Electrical contacts cause a spark that burns (melts) needles and small disposable tools. .

Another important point? the slit where the needle is inserted which? protected and does not create an escape of sparks during its destruction.

The machine works only and exclusively when a needle or a metal tool is inserted. Why? the metal poles are normally never in contact with each other.

When the needle is inserted into the slot, contact is made between the two poles, which by means of the electric current (not dangerous because it is transformed from alternating to direct) melt the needle or the metal instrument.

Under the machine table there is a door that allows to eliminate the residues of the burnt needles without having to touch them.

This system also solves the problem of the disposal of toxic and dangerous waste since? once the needle or the instrument is burned, its residues are no longer? sharp and are completely sterilized.

Detailed description of the machine There are 4 drawings attached to illustrate how? constituted and how the machine works.

Drawing 1; Illustration of the internal electrical circuit. Drawing 2: Illustration of the electrical system that burns the needles

Drawing 3: Description of the operation of the electrical system. Drawing 4: Illustration of how the machine is used in daily practice

FIGURE 1

This car ? internally equipped with a socket for recharging the same n. 1, electrical circuit protection capacitor 2, 9 volt DC accumulator 3, safety switch to disable the machine A, slot for needle insertion 5, electrical contacts 6-7, needle waste collector 6 , door for the elimination of the same 9?

The machine is charged with direct current by means of socket 1 from a transformer which is inserted into a normal 220V socket.

After 8-10 hours of charging the machine? ready to use; with one charge you can destroy about 200 needles continuously, after which? the machine begins to lose power, destroying much more? slowly.

Caution: ? it is advisable never to completely discharge the accumulator 3 to avoid irreparably damaging it. If so, due to unavailability? leave the car charging for more? of 10 hours the circuit breaker 2 proweder? to block the loading avoiding overheating.

By pressing the A key, the machine is activated and it will be? It can be made to work by inserting the needle into the slot 5 which is perfectly insulated so as not to damage the operator. Below the slit A there are the contacts 6 which are rotating to facilitate the insertion of the needle, while the contact 7 closes the circuit causing it to melt.

Contacts 6-7 are made of frogs, a metal with high electrical conduction and long life.

In switch 4? inserted a safety system that automatically blocks the operation of the machine when, due to work overload, it overheats. The residues of the burnt needles fall into the container 8 which, due to the high melting temperature, are sterile and harmless as they are no longer? sharp.

Are the residues removed by opening the door 9?

FIGURE 2

In figure 2 the collector 8, the contacts 6-7 and the discharge slot 9 are produced in projection.

You will notice? that the contacts 6 are round and rotating for the best insertion of the needle. The contact 7 has a particular inclination which facilitates the fall of the molten metal residue towards the bottom of the container 8 where the discharge slot 9 is located.

FIGURE 3

In this illustration? container 8 shown in section.

It comes like this? focused the needle burn system. It is evident that the needle can? touch both one or the other retante cylinder 6 and in any case it will go? touching contact 7 causing burning.

This system? was so? designed to facilitate, but above all speed up the operator's work.

FIGURE 4

This figure describes the operation of burning the needle on the practical side.

Illustration 11: the needle is inserted and pushed into the slot until it touches the electrical contacts (there is no need to look as the needle is automatically guided by the rotating contacts).

Drawing 12: the needle, pushed downwards, is consumed by the fusion in its metal part, leaving the syringe handle intact.

Drawing 13: Once the needle is burned, the machine stops giving the possibility? the operator to lift the syringe upwards. Also concluded this operation, the operator can? reinsert the protective cap of the syringe without worrying about it being damaged.

In fact, after all this the needle will be? reduced to a small rounded residue, sealed, sterilized.

This system will be able? be subject to any changes both in terms of contacts and structure in the spirit of improving the machine from a functional and safety point of view

CONCLUSIONS

The machine for destroying needles and small metal tools used in the daily practice of medical environments uses a system of electrical contacts that allow the melting of steel.

Have you described the internal and external structure of the machine that will come? called with the name of BURN-NEEDLE or burn needles.

The used needles are inserted in the appropriate slot described in drawing 1.

This sets in motion an electrical circuit by pressing the needle into the slot and is removed by pulling it up.

The residues collected from the special container can be easily eliminated, avoiding the problem of disposing of particular toxic or infected waste.

II Burn-Needle? was conceived with a spherical shape after an ergonomic and stylistic study.

In fact, the slit positioned 50? facilitates the insertion of the needle in any position the operator may find.

EXTRACT

This invention consists of a machine equipped with an electrical system that allows to destroy needles and small disposable medical instruments.

It collects the residues of the instruments, after having melted them and sterilized them, which are eliminated without any more? touch them with the

dwarfs.

Claims (1)

CLAIMS 1) The novelty? essential of the appliance lies in the "Contact-Container" structure 2) The contact cos? structured facilitates to the maximum the maneuver of destruction of the needle in terms of time. 3) In this way it guarantees continuous and constant electrical contact between positive and negative poles. 4) The metal "Contact-Container" performs the double action of collecting the metal residues of the melted needles and of supporting frame for the positive and negative contacts. 5) The "Contact-Container" cos? designed considerably simplifies the construction of the device, reducing production costs at an industrial level.
