Description

 RECYCLING OF CUTTING MEDICAL WASTE

AND PUNCHERS

OBJECT OF THE INVENTION

The present specification refers to a PCT application of the invention, relating to a small portable device with means for cutting sharp and sharp objects into small fragments or sections through several blades placed parallel to each other.

Destroyed these objects in small fragments, then and once the internal metal deposit of this equipment is filled, the waste will be sterilized by means of gases or sterilizing chemicals that are located in a continuous deposit to that of the waste and separated between if by a specific opening membrane.

Waste cut into small fragments and sterilized by the action of gases and chemicals can be disposed of in the common trash and recycled as metals, since the entire tank and its contents are metallic.

FIELD OF THE INVENTION

The applicant is aware of the existence of a plurality of health and ecological problems with sharp medical waste.

The applicant has knowledge of devices or equipment that can cut the needles from their base with the cone and make the problem disappear temporarily, since these equipment does not destroy the needles in small fragments, thus preventing the complete destruction of these sharp objects and stabbing

Nor is it known to the applicant that this waste can be sterilized in a small portable device by means of gases or chemical sterilizers housed in the continuous deposit to that of the waste, forming a single body said deposit.

And much less, the applicant is aware that this waste already destroyed and sterilized, can be recycled as metals; therefore, the applicant adopted that the material of said deposit be composed of derivatives or alloys of metals.

DESCRIPTION OF THE INVENTION The invention affects a portable device of small dimensions of mechanical action, which carries inside a series of blades (several mowing blades) held between them by an axis. Said blades are actuated by means of a lever, which when exerting pressure on them; will move the blades by mowing the needle or scalpel blade in as many fragments as blades the equipment carries.

The equipment is housed inside a metal tank where the needles destroyed and fragmented by the mowing blades are housed. Said tank in its lower part, has another tank associated in which a gas or chemical sterilizer is housed inside. Both tanks form a single body, being separated by a valve that is connected to the tank that carries the sterilizer; When turning both bodies on its horizontal axis and inverting the deposits, the valve will break, leaving the chemical sterilizer free and flooding the waste deposit of the destroyed needles, until they are sterilized in a certain time.

Once the tank has been sterilized, it will be recycled as metal, since its composition and its content are made of metal.

PREFERRED EMBODIMENT OF THE INVENTION

Following the figure number 1, it can be seen in section how the apparatus is configured as a general referenced body (2), in its lower part a riveter (4), anchored to it a lever-shaped body in its opposite upper part (1 ) and in whose lower part there is a hole (3) to compress the special needles of dentists. Inside the equipment there is a metal tank (5) with a filling sight glass (7) and a protective back cover (6) to facilitate the siege of the equipment.

The mobile blades (8) and fixed blades (9), a fixed groove (10) and a piece to guide the needles to their insertion hole (11) are already in the upper part of the device. In figure 2, the syringe (12) is inserted with its needle (13) as indicated by the arrow until it stops.

In figure 3, when the lever (1) is operated, the moving blades (8) will move in the direction of the arrow through its axis (14) until the needle is cut with the fixed blades (9), leaving the converted needle in fragments (13) as the drawing shows.

In figure 4, the syringe (12) is introduced with its needle (13) as indicated by the arrow until it stops. In figure 5, the lever (1) will now press the needle (13) through the movable blades (8) while pressing it and we will move the syringe in the direction of the arrow. In figure 6, holding down the lever (1) we will move the syringe in the direction of the arrow.

In figure 7, the needle was separated from the syringe by cracking, being deposited this whole inside the metallic deposit.

In Figure 8, a scalpel (14) with its blade (15) is inserted into the equipment as indicated by the arrow.

In figure 9, the lever is operated in the direction of the arrow by operating the moving blades (8) by cutting the scalpel blade (15) into a fragment.

The springs (16) will return the moving blades to their resting position when the lever (1) stops pressing.

In figure 1O _{5 the} whole process is repeated again, lowering the scalpel with its blade as indicated by the arrow and repeating the entire previous process, leaving the scalpel blade fragmented (15) as shown in the drawing.

In figure 11, the metallic internal tank that the equipment has with its system of hook to the equipment (17) its filling window (7) and its indicator seals of the needle compartment (21) and the sterilization compartment (22) ).

In figure 12, the tank with its needle compartment (18), the sterilizer compartment valve (19) and the sterilizer compartment (20) can be seen in section.

In Figure 13, the tube of the needle compartment (18) rotates on its horizontal axis, breaking the internal valve (19), until the two seals are joined (21 and 22) to sterilize the waste compartment ( 18) with the gas.

In Figure 14, the waste compartment (18) has been enlarged to occupy the total volume of the metal deposit and thus have greater capacity, although to sterilize this deposit it must be done through the autoclave process.

In figure 15, a dentist needle (13) with its protective sheath (23) can be seen.

In figure 16, the needle with its sheath is inserted through the opening of the equipment lever (3); You can also see the filling indicator of the internal tank with its slot in the device (24). In figure 17, the lever (1) will move in the direction of the arrow by pressing the dentist needle against the riveter of the equipment (4) to bend the needle into the cone of the latter, thus avoiding that we can prick with this needle rest.

In figure 18, it can be seen how the dentist's needle (13) is left after being riveted or compressed as indicated in figure 17.
