FR2863171A1 - Anti-microbial handle e.g. for hospital use has core or rod covered with sleeve containing a biocide of mineral or metal salts - Google Patents

Abstract

The handle consists of a support (2) for a core or rod (5) with a coupling (6, 7) at each end - one for connecting to the support and the other to receive a cap (8). The core or rod is fitted with an anti-microbial sleeve (10) containing a biocide containing mineral or metallic (ferrous or non-ferrous) salts, or a formulation based on a zirconium- sodium-silver ion exchanger. The sleeve itself is made from natural or synthetic rubber, a monomer or polymer plastic foam or textile material.

Description

Human Antimicrobial Gripping Pointer

  The present invention relates to principles of design and manufacture of a handle for antimicrobial human grasping and its various fields of application. It is now essential to provide the guarantee of irreproachable hygiene in all sectors of professional activities and even in homes. The microbial strains become more and more resistant and are transported very quickly from one place to another. An example of this is the hygiene of hospital staff, clinics and out-of-town visitors who allow microbial proliferation by the hands commonly referred to as manual transmission. This leads to epidemics and considerable infections of people newly operated by nosocomial contamination.

  A very large vector of contamination is to mention only these without the list being exhaustive: the door handles in general, the stair railings, the wall supports, the handles of trolley or cupboards, the shower heads, toilet brush, shower seats, pull-downs or toilet seats, shower trolleys ....

  We will remember that any support can become a nest of microbes more or less important depending on the texture or the material that composes it. In addition, the cleaning and disinfecting products often have a limited spectrum of activity on certain types of microbes and fungi and have only a short duration of persistence over time. To this must be added the physical defilements which will drastically limit the bactericidal or virucidal or fungal action.

  There are many patents dealing with this subject. The patents DE 200 00 432, FR 85 18117, CH 482 897, CH 642 424, FR 98 08790, FR 85 17646, FR 01 05 776.

  These different patents have the particularity of adopting a wet disinfection system by means of the impregnation of the pre-emptive part and the diffusion of the active ingredient at the surface of said pre-emptive part. These systems have many disadvantages.

  The action of the active ingredient is quickly saturated and does not maintain its performance over time. According to its intrinsic characteristics, the impregnating liquid volatilises and dries very quickly. People using these systems may end up with a treatment product on their hands that may cause chemical burns or allergies. The products that will impregnate the handles must be stored in a specialized place and good management ....

  The invention will serve as a way of substantially avoiding these and other disadvantages and remedying them.

  The new antimicrobial gripping handle has very interesting advantages over the handles and the various applications described above. The object of the invention is to provide an antimicrobial gripping handle and its derivatives of improved applications while retaining the advantages. existing products.

  For this purpose, other features and advantages of the invention will appear on reading the detailed description which follows, description made with reference to the accompanying drawings, in which: FIG 1 shows schematically a conventional handle and provided with An antimicrobial sleeve With reference to FIG. 1: The antimicrobial human grasping grip (1) is formed by a support (2): integrating a mechanism for opening and closing and returning (3) a median opening or a median depression (4) allowing the square metal to take position in said opening and in the passage of the lock of the door and at the same time to connect the two handles together and which will be fixed on the opening of the door. The support also comprises a core or rod of round section (5) and which at each end has a fixing means (6, 7) (for example a thread). One end will take a position in the support (2) and the other end will receive a closure cap or a closure (8) and accusing itself a closing closure (9) fitting on one end of the stem, or circular soul.

  According to a variant, the core or stem may be of different section and of varied shape (square, rectangular, oval ...). It seems logical that this same stem can receive growths, spurs, striations, perforations .... An antimicrobial sleeve (10) will respectively take place length of the rod (5) coming into contact by the support (2) and from the back with the cap- reside in the sleeve made of rubber, or a plastic material a textile woven or non-woven an antimicrobial agent remanence agent without producing or releasing toxicity to a human organism. The sleeve will include at the time of manufacture a biocidal agent composed of inorganic or metallic salts (ferrous or non-ferrous) - (alloys) or a zirconiumsodium-silver ion-exchange phosphate formulation.

  According to a variant the sleeve (10) will be made of a material forming the support, we will remember for example (plastics: PET, ABS, PVC, PP ..., ferrous and non-ferrous metals, wood, resins ...) and a coating including the zirconium-sodium-silver ion exchange phosphate biocide. It may be noted that the support forming the receiving die of the sleeve may be designed in the same characteristics as the previously described sleeve.

  One can easily imagine another variant of a type of handle. The support of the handle (1) is made of antimicrobial plastic based on zirconium-sodium ion exchange phosphate and admit an antimicrobial sleeve described by the same biocide and the same manufacturing techniques.

  Another embodiment will make it possible to apply a coating such as polyamide known under the name of Rilsan (Trade Mark) 15 throughout the front with clasp (8).

  The peculiarity of the antimicrobial invention. This sleeve may be synthetic or natural, a foam, monomer or polymer or composite or woven incorporating a biocide or chemically stable and having a large which is a vegetable paint, ecophilic and nonflammable, isothermal, highly resistant to shocks and UV including the a biocide based on zirconium-sodium-silver phosphate ion exchanger on all human gripping supports and in particular the different types of handle allowing the opening or closing of a door or a piece of furniture or a valve, 'a tap... . The invention and its advantages take into account the many variants and shapes of handle that may exist or to come and the different principles of maintenance or fixation.

  Referring to Figure 2: A variant of the manufacture of a handle is formed by a rigid or semi-rigid support (20) with its holding and fixing systems (21) will receive a plate of elastomer or rubber or plastic material including the zirconium-sodium-silver ion exchange phosphate biocide (23) and which will take position in the grooves provided for this purpose (24). This system allows flexibility in formats and shapes to adapt to the conformation and geometry of all objects having the principle of opening and / or closing.

  To satisfy another principle of application it may be retained that after the manufacture of an antimicrobial element in different forms (sleeve, plate, cube, ball) having patterns, inlays, perforations is added to one of their part or in totality on one or both sides a repositionable or permanent adhesive for some cases.

  This variant will allow the element including the antimicrobial to attach and adapt to all types of media.

  The principles of manufacture and the various forms and types of construction including a zirconium phosphate-sodium ion exchange biocide as a coating or in the parent material (will design the support and the gripping elements) itself according to the present invention is will find and necessarily apply for professionals and individuals on the following derived objects and applications.
