Sterile dispenser for dental polishing discs

Technical sector

HEALTH SECTOR DENTISTRY

The objective of the present invention is to avoid contagion and cross-infection in dentistry by minimizing the manipulation of instruments.

Background of the invention

THERE IS NO PREVIOUS TECHNIQUE THE DISCS ARE TAKEN WITH THE HANDS

In the health sector and within the specialty of odonto-stomatology and in a restorative, aesthetic and functional plane, the use of burs and polishing discs is constantly necessary. For this, there are single-use or disposable sandpaper abrasive discs, necessary for polishing almost all dental interventions and that it is necessary to manipulate them manually, that is, you have to grasp them with your fingers, of course. gloved, out of a pile because there is no unitary dispenser and therefore they are served in non-sterile bulk bags.

This is a waste of time in handling them and especially the possibility of infectious cross reactions between patients since they are used for many patients and must be taken from the same place.

That is why, we have created a model that until today had not been thought and manufactured an instrument that avoids manual contact.

In this work we have created a simple model that meets the asepsis and sterilization requirements of said discs, minimizing contacts and fulfilling the objective of preventing their undesirable manipulation by means of a simple instrument.

Explanation of the invention

We have invented a Utility Model in the area of health sciences to avoid undesirable infections, whether by fungi, bacteria and viruses.

CONTAINER-DISPENSER OF ABRASIVE DISCS FOR DENTISTRY

Specifically, within the Odonto-Stomatological specialty of medicine, there are sandpaper or abrasive discs of various thicknesses and sizes that are used for 90% of almost all daily dental processes, (polishing of prostheses, fillings, inlays , enamels, ceramics, etc.), to polish, adjust, reduce and shine, both to restorations and to the teeth themselves.

These discs are disposable, usually made of paper, cardboard and even plastics, and to manipulate them it is necessary to place them on a stem called a "mandrel", which is adjusted to the disc by pressure on a metal clip, which is mounted on an electronic micro motor that rotating at high revolutions is able to polish, wear and shine the different materials and / or processes that are treated in dentistry.

The problem is the possibility of contagion, since the discs are served from the supplier in bulk in bags of 100, this means that they are stacked one on top of the other and that it is necessary to pick them up with tweezers, a task in itself cumbersome, slow and little precise, which makes their rapid placement not feasible and which also includes the fact that they can be adhered to each other due to surface tension, which is why sometimes it makes us take the discs with the hand, obviously gloved, but that of this In addition, it could produce cross-contagious reactions between this patient and the piled-up discs.

To avoid these undesirable effects, pick-and-place disturbances, and possible cross-infectious reactions, we have devised a simple utility model, a simple plastic tube, adjusted to the size of the discs, which are universally sized, so that can be caught without maintaining close contact with them, in addition to preventing the possibility of catching more than one. Said system is made up of a simple plastic tube with a screw cap and that fundamentally carries a pen-type spring, inside, this is capable of holding and lifting or pushing said discs as we take them with the mandrel and from unit to unit. In this way, simple, efficient and fast, as well as, obviously, totally aseptic, the discs go upwards from the container to be able to take one by one more necessary discs in totally sterile ways. In addition, each container would have a type of abrasive disc depending on the thickness of the sandpaper and thus be able to quickly choose the type of disc to be used by container colors.

Thus, the components of this utility model would be the following:

• A plastic tube of a certain diameter given by the discs to be contained. Dental medical device that consists of a simple tube of the material that is preferred, and that acts as a container-dispenser, with a certain internal diameter that should be slightly greater (normally 0.1 mm) than the total diameter of the polishing disc that we want to store. , so that these are completely adjusted, but with enough play (0.1 mm) so that the spring can drag them without internal friction so as not to lose the action and the ejection force of the spring. In addition, the length of the container-dispenser tube could vary depending on the number of discs that we would like to insert into it.

• A closing cap to stabilize and keep the interior assembly sterile, avoiding the entry of microorganisms as well as their manipulation outside the clinical context. In this way it could arrive already sterile from the factory or it could be filled with the discs in the clinic, to be sterilized later by the operator.

• An activating spring located inside and mechanically coupled to the internal base of the tube, threaded and held in its internal and most distal part of it.

- It consists of a spring with a torque or a certain action pressure, the type of spring used in pens, which depending on the number of polishing discs that we want to place and the size of the container-dispenser tube, can be larger or smaller strength, which would depend on its thickness and material.

- This metal spring would be adapted to the internal base of the plastic tube at the bottom of it. This would be fixed on the plastic with a simple clockwise turn so that the spring would be inserted in the recess or circumferential groove of the bottom of the container. This device, called a semicircular channel or simply a circular recess that, like a semicircle and manufactured in the internal base of the container-dispenser tube, serves to mechanically hold the distal end of the spring and adapts to the semicircular recess or channel, with a simple movement in clockwise which makes it inserted into the base of the tube, in this way we avoid the unwanted mobility of the spring, remaining perfectly fixed to the base of the tube. Thus the upward action by negative pressure, exerted by the operator when pulling the polishing disc up or downward by positive pressure when inserting the polishing discs, will be exerted without impairment and without the possibility of disinsertion of the disc.

• An internal flange inside the tube, bypass or circular enlargement 0.1 mm wide and equal in height (0.1 mm) located at the head of the container-dispenser tube (figure 6).

This device is located on the inner edge of the outlet of the container-dispenser tube and is a protrusion of 0.1 mm or more, depending on the force that we want to give to the assembly of the spring and the polishing discs. This internal edge or internal contoured edge is made of the same plastic as the container-dispenser tube and will be between 0.2 and 0.1 mm, depending on its thickness of the fastening that we want to give to the set of stacked polishing discs. within the system. Said protrusion and / or plastic inner rim, prevents the accidental exit of the discs once the cap thereof is opened. It must be thick enough to guarantee the stability of the discs and hold the pressure exerted by the spring on said stack, and also be thin enough so that when exerting a negative pressure the operator, or extraction towards the outside, is able to remove said polishing disc (thanks to the soft consistency of the paper on the disc) without the next one coming out, which would be trapped by the protrusion or internal plastic rim.

• Some polishing discs, which have in their central part a small metal attachment that fits by pressure into a stem or "mandrel" that in turn is placed in an electronic micromotor that rotates it at high revolutions to achieve the proper polishing of the teeth or restorations of the patient's mouth, as well as to solve problems of undesirable contacts, friction of small dental fractures and of broken prostheses and misadjusted fillings, as well as for dental cleaning and to give shine and softness to the dental set. Thus, every time that said paper disk is worn or used, we must change it for one equal to or with a lesser degree of abrasion, simply and with the stem or "mandrel pressing against the center of the disks that are already held by the spring. , it would be sufficient to fit said mandrel into the next disk of the container tube and simply with a negative outward traction, overcome the mechanical resistance that it exerts on the exit of the disk, the flange or circular enlargement of the internal face of the head of the tube. plastic.

We describe the sequence of the procedure below:

Once the polishing discs have been loaded into the dispenser-container either at the factory or by the operator, the set must be sterilized and sealed.

Once in the clinic, the closing cap is opened.

The mandrel, inserted in the electronic micro motor, is placed on the central notch that carry the abrasive discs already stacked inside the container and pressed onto the spring.

We make a positive pressure towards the disc to place it and hold it to the chuck.

Once inserted into the mandrel, a negative pressure is exerted out of the container with which the disc passes over the inner rim at the same time that the next disc is trapped by this same rim.

Once used, the cap is closed to avoid cross-infection.

With this system it is impossible to manipulate the polishing discs with the hands and between them, (they are administered together in bags of one hundred), so that the passage of germs and cross reactions between the patient and the rest of the discs would be completely controlled , it would be null. In addition, there would be the double advantage of being able to manage the polishing discs, much faster and easier without having to waste precious time searching for the disc, trying to insert the mandrel in the center and also avoiding the very frequent and annoying fact of that the discs are glued to each other by surface tension and it is more problematic to pick up just one.

In summary, the system consists of a simple plastic tube with a screw cap and that fundamentally carries a spring (the kind normally used in pens), inside, it is capable of holding and lifting or pushing these discs as we take them with the chuck and from unit to unit. In this way, simple, efficient and fast, as well as, obviously, totally aseptic, the discs go upwards from the container to be able to take one by one more necessary discs in totally sterile ways.

Drawings of the model are included in which the simplicity and maximum usefulness of the model can be appreciated, as well as its minimum manufacturing price, for a function as important as that of facilitating and advancing the work, as well as avoiding possible unwanted infections.

This inexpensive system, easy to build and with great application capacity, has the advantage that it can be reused as many times as we want, if the manufacturer does not provide it to us and it is by inserting the discs, stacking them in the tube, after purchasing them in their bag. in bulk, being able to be sterilized.

It is also possible that due to its simplicity and low cost, it is the manufacturer that chooses a reusable or disposable and / or recyclable tube or container, even with a color code for each container to indicate the type of polishing disc that is in its interior varying the colors by the index of aggressiveness, its size, even shape, and in this way facilitate the task of the dentist, by not having to stack the discs in the container. Practically its cost would be less than that of a pen, but with much higher expectations, making the task of polishing as easy as possible and avoiding possible unwanted infections by fungi, bacteria and viruses.

Preferred embodiment of the invention

As seen in the drawings, the embodiment of the invention is clear.

We can see in the drawings (figures 1 to 6) the sequence of the utility model and its dental use.

It is simply the manufacture of a plastic tube (2) with or without a cap (3) of a certain diameter that is shown in the drawings and that will depend on the size of the polishing discs (7) that exist on the market (we know two types of diameter), in this case the 3M house manufactures Sof-lex whose outer diameter must coincide with the inner diameter of the tube minus a few tenths so that it enters smoothly and remains horizontal and thus can be distributed in the container in a uniform and whose insertion should thus be easy, fast and effective, both manually by the operator (dentist), and in an automated way through insertion by a machine built for this purpose.

Once the discs (7) have been inserted, both manually and automatically on the spring (4) inserted in the bottom of the tube (2) or container, this will exert an upward pressure, which is why an occlusion system is necessary that avoid the exit of these, this is easily achieved by means of an internal flange (5) or protrusion formed in the mouth of the tube in the internal circumference, of a size wide enough so that the discs (7) do not come out by themselves, and fine enough so that these, the discs, can come out with the pressure of the operator on the chuck outwards, this is at least half a millimeter, slightly smaller or smaller than the diameter of the discs, thus the operator pulling the chuck outward with sufficient pressure, not excessive, could keep the disc (7) inserted in the mandrel and use it on the patient's teeth, without having any contact of the disc with the hands, and thus avoid, which exclusive and most important function, any cross infection between the patient and the rest of the discs, since these could not be manipulated with each other and thus avoid the exchange of germs. Also the function of speed, comfort and ease of use is inherent in the function of this model, 'and therefore no less important.

In conclusion, it consists of the manufacture of a plastic tube (2) with certain measures, with a cap (3) threaded or not, and with some notches included in the plastic of the tube (2) and that are two:

• Bottom, semicircular channel (5) or notch, embedded or fused in the bottom of the tube (2) to hold the spring (4) at the bottom of the tube, of the pen type, to exert a force sufficient to push the battery discs out.

• Upper, at the mouth of the tube (2) an internal flange (6) or circular enlargement around and in the internal part of the container, which protrudes slightly, and whose function already described is to hold the discs (7) preventing their exit passive, but leaving its output active by means of a negative extraction pressure.
