Description

-1 - The present invention relates to the principle of manufacturing a

  instrument or hand tool for curettage, absorption, sanitization, sampling of all conduits which have natural or artificial orifices, for example the auditory canal, the cavities of the nasal fossae and the various constituents constituting a living or artificial organism .

  This curettage, sanitizing instrument or hand tool,

  The purpose of absorption, of sampling is to replace by its new anatomo-ergonomic design, the structure, the assembly, the manufacturing process, sticks commonly known as "cotton swabs".

  Conventional cotton swabs usually consist of a stem

  flexible plastic material which receives at each end a tip or head in cotton texture.

  The design of such a hand instrument cannot give full satisfaction. The curettage effect is not easy. The textile fiber which constitutes the end piece is easily detached to become a foreign body causing irritability or even damage to the ear canal or any other meatus. The tip introduced into the ear canal Zo does not remain integral with the rod when the pressure exerted in the ear is too strong. The bleaching and impregnating agent

  specific to the textile fiber constituting the tip can be the genesis of an allergy.

  The current cotton swab cannot significantly produce both an effect

  curettage by trapping the emitted particles, while absorbing a mood developed by an organized body.

  -2- The manufacturing frame does not make end caps or heads

  symmetrical cotton swabs. The constituent elements forming the whole require significant implementation and resources.

  go Subsidiary drawbacks have already been revealed by French patent n 2,600,883 and patent application n 97 03052 in order to

  somehow remedy the disadvantages described above and those cited in said patents.

  The invention will be used so as to avoid to a substantial extent

  the disadvantages and others and to remedy them.

  The present invention and its advantages will appear better in the

  description of the manufacturing principle of an instrument or hand tool for curettage, absorption, sanitization, sampling of all conduits which have natural or artificial orifices.

  The inventive step relates to a principle of manufacturing an instrument or tool for curettage, absorption, sanitization, sampling, the general characteristic of which is a rod or rod made of plastic material with axial symmetry, having both a multidirectional flexibility, elasticity and flexibility controlled to ensure efficiency, good grip and good support of the instrument or tool. These flexibility and elasticity will be determined according to the desired effects when the components forming the mother material of the rod are included. The

  profile of the rod rod in its transverse and longitudinal form. 5 will accept a geometric figure (for example of section: round, square, octagonal, ovoid ...).

  A predetermined profile of convexity or concavity of the rod of the rod will preferably be given at the time of its manufacture.

  -3- The rod rod can be hollowed out or provided with a channel

  medullary which serves as a reservoir for a substance or to convey a fluid or liquid. The end of the rod rod will have in its median axis a cavity which will lead to a notch whose length and width will vary significantly from the defined model.

  The notch and cavity will serve as a receptacle and secure clasp. The sides of the notch must perfectly fit the part which comes to be included in the cavity by contiguous edges to leave no space for any roughness. The edges of the end of the rod rod in the cross-section direction will be flat and free

  on half the circumference. The other half of the circumference will have an integral part in the shape of a bulb with a slightly rounded dome which, for medical reasons, may tend towards an ovoid or almond or pear dome.

  The entire bulb will consist of several flexible and elastic bands supporting a twist-rotation. These strips will be bevelled on one edge or on both in order to favor curettage and to trap towards the interior of the bulb the particles 0 undesirable for the living organism. Depending on the model, the strips will have a different spacing depending on the desired effect. The bulb will be divided into two parts in the longitudinal direction and held together by a clip serving as a hinge. The part of the bulb not integral with the rod rod will have at its base an axis det5 shape and dimensions identical or even similar to the cavity of the clasp of the rod rod. Indeed, the part of the bulb not

  integral with the rod rod will be folded back and snug or snapped into the cavity and the notch-clasp of said rod rod thus forming the complete instrument which is the subject of the present invention.

  -4- The bulb of the curettage instrument according to the method of manufacture and

  embodiment of the mold will be formed in one piece of plastic material by flexible and elastic strips or bands supporting a torsion-flexion combined according to a movement05 of helical or semi-helical assembly.

  The part of the instrument or hand tool called the bulb or head of the stick will be manufactured according to different models. We will note that the bulb can be designed by a plurality of strips or lamellae whose central core will be hollowed out.10 In another embodiment the part of the hollowed bulb will be filled with a plastic material having similar characteristics,

  either to be more flexible or firmer, as well as more or less pronounced porosity. According to a variant, the bulb will be designed by flexible plastic bands and the inside forming the core by a natural fiber (cotton), or an artificial fiber (viscose), or a nonwoven.

  In another embodiment, the bulb may be composed of strips or strips of nonwoven fabric with a core of natural fiber or of artificial, synthetic fiber. The strips or strips of the bulb, or only the dome, or the assembly may be at the time of their manufacture, integrate structural drawings or patterns, for example: (teeth, spikes, striations ...). The advantage of these different combinations and associations will be obvious to those skilled in the art. The functions of curettage, absorption, sanitization,

  sampling of all conduits which have natural or artificial orifices are not always easy to access or easy to reach.

  -5- In this spirit the instrument or hand tool will receive between the rod and the

  bulb an integral joint so that the head of the stick becomes multi-directional taking the anatomical configuration.

  For better support, dexterity and grip between the fingers of the manipulator, the rod rod will receive ergonomic grips

  in order to facilitate the introduction and possibly the rotation. Furthermore, the rod of the stick according to the invention can carry two opposite and slightly curved parts which can take the form of a fingerprint.

  To differentiate the instruments or hand tool in relation to their

  function and their constitution we can provide a color code, for example: (the red stick + white bulb) or (white stick + green bulb). The application of color can be done in full on the part to be treated, by a ring system, by an alphabetical inscription, by a numeric or alpha inscription.

  digital. The bulb according to the invention can be supplied at the factory pre-impregnated with a liquid or pasty substance. In order not to suffer a loss of ZO produced by drying or drying, it will be ensured that the bulb or the head of said stick is covered with an impermeable film.

  meant for that purpose. It is obvious to a person skilled in the art that for technical reasons which are specific to him, covering with a specific film over the entire instrument is achievable. Z5 filming the hand tool will be recommended to make it sterile or when it is used in a sterile environment.

  -6- In order to facilitate the packaging of such hand tools, they will be linked to each other by means of their protective casing at their ends, to form a chain and be placed in a dispenser box. 05 The manufacture of instrument or hand tool according to the invention is possible thanks to modern techniques and means which are

  plastic injection, thermoforming, thermomolding. For this it is fundamental to use plastic raw materials such as for example: "elastomer, polypropylene, 0 o polyethylene, PVC ...".

  The stick will preferably be shaped in one piece. But for technical and / or manufacturing reasons it will be

  necessary to shape and assemble several pieces.

  In another embodiment the stick will be shaped and worked out with

  at one end of a louvre bulb and at the other end of a manual suction and / or delivery system.

  In another embodiment the instrument will be prefabricated in the factory

  as a single-use surgical or sampling swab introduced into a container commonly called for example: t "test tube".

  The characteristics and advantages of the present invention

  will appear better during the description which follows, carried out by way of example according to a preferred embodiment with reference to the accompanying drawing in which: .25. Figure 1 is a perspective view after injection of the instrument or hand tool according to the invention;

  Figure 2 is a view of the instrument with the articulation system of bulbs or multidirectional heads; FIG. 3 is a view of the instrument provided with holding or gripping means, with a protective film with its attachments,

  including only the bulbs or heads of the stick.

  The principle of manufacture of an instrument or hand tool for curettage, absorption, sanitization, removal of all conduits which have natural or artificial orifices according to the invention, generally designated by the reference 1, is consisting of a rod or rod 2 having at at least one of the ends of said rod a notch or slot 3 which opens onto a cavity 4 forming the medullary canal of the rod, one of the external edges of which has on a part of its circumference a bulb 6 made up of strips 7. The upper part of the bulb called the dome 8 incorporates a pivot hinge 9 making it possible to

  receive the counterpart 10 of the bulb 6.

  Half of the bulb 10 is provided at its terminal end with an appendage 11 of geometric shape substantially identical to the stem

of stick 2 and of notch 3.

  Appendix 11 is in its sense a key clasp which allows

completely form the bulb 6.

  ZO It is understood that the bulb 6 can be hollowed out or full depending on the

  function for which it was intended.

  According to another embodiment, the stick 2 will have a channel

  medullary acting as a reservoir.

  -8- The spacing of the plastic and elastic strips 7, as well as their number is determined by the geometrical figure and the configuration of the bulb. Preferably the bulb will be made so as to respect the anatomical imprint so as not to injure it and to remain effective. The instrument or hand tool consisting of the stick 2 and the bulbs 6 for a better application and introduction is constructed with a semi-rigid and multidirectional articulation 12. The penetration of the bulb head will be easier.10 The stem of the instrument 2 is capable of holding or gripping means 13 convex or concave forming either a lug

  anatomical is a fingerprint. In addition, the stem of instrument 2 for better application and quick reading will be provided with a partial or total color code. The head of said bulb may, for the same reasons, receive a different coloring or pigmentary appearance 15 than that of the rod rod 2.

  During the manufacture of the instrument according to the invention, the heads forming the bulb may be covered with an impermeable film 16 preventing the product from leaking out or drying out or even remaining aseptic. In another characteristic, the instrument according to the invention will be completely covered by said protective film.
