Definitions

  • This invention concerns the dental field and in particular the equipment that is usually used in a dental practice and/or in the operating room in general.
  • Tension, anticipation anxiety, fear and pre-conceived ideas are an obstacle to treatment that can become insurmountable, and often these psychological states can be further accentuated by pre-existing conditions such as stress, disease but also simply menopause and menstruation.
  • a state of anxiety or fear can frequently produce functional disorders on the patient, ranging from minor illness to more serious physical problems.
  • small ailments i.e. those that are resolved spontaneously by the interruption of dental care in the chair, can find a distinction based on the adult subject and a pediatric subject.
  • the first case is represented by the oral or intravenous administration of anxiolytic drugs (e.g. benzodiazepines) or even, even in conjunction with these anxiolytic drugs, by means of the administration during the dental session, of nitrous oxide whose analgesic-sedative properties are known.
  • anxiolytic drugs e.g. benzodiazepines
  • nitrous oxide whose analgesic-sedative properties are known.
  • a dental unit group from now on a unit group, it is intended an assembly consisting of a support frame for a chair, on which the patient sits, and other parts connected to that frame also by means of articulated elements that serve as support for other parts such as a lamp to illuminate the area of intervention, a handpiece holder, a screen, etc..
  • the problem that it is intended to further address is that of bacterial and microbiological contamination of the patient (fungi and viruses) in environments where health care is provided and, more specifically, in those environments where care is provided in the oral cavity with dental instruments, where he or she is therefore particularly disadvantaged in terms of exposure to any infection and where this leads to the release of particles into the aerial environment of the office.
  • LAR laminar air flow
  • HEPA High Efficiency Particulate Air
  • the laminar flow to date ISO 5 is necessary for operating rooms of prosthetic surgery and/or for example in cardiac surgery, transplantation, orthopedics, neurosurgery and vascular surgery. In these areas, it is clear that the bacterial load must be low in order to reduce the post-operative infection risk as much as possible. In this case, the unidirectional laminar flow must cover the operating field and the instrument's table.
  • an additional aid would be poorly ergonomic, this deconcentrating the dentist while performing his work if in addition to having to adjust the light he or she must also adjust the airflow.
  • Document EP 2 679 213 A2 discloses a boom assembly configured to movably secure equipment to a ceiling or plenum extending from the ceiling.
  • the assembly may include an arm sub-assembly secured to the ceiling, equipment secured to an end of the arm sub-assembly, and an air delivery member extending through the arm sub-assembly.
  • the air delivery member may include a first end in communication with an air delivery chamber within the ceiling or plenum, and a second end in communication with air passages formed through the equipment. Airflow is directed from the air delivery chamber out through the air passages formed through the equipment towards a target location.
  • One of the purposes of this invention is to describe a ventilating lamp device that provides clean air without the need to introduce inconvenient additional aids into the dental practice.
  • one of the aims of this invention is to provide the user with a device that simplifies the management of lighting, ventilation and correct direction of the air flow(s) supplied for simple use of the same.
  • one of the aims of the present invention is to provide an all-in-one device that is advantageous in terms of solving a number of known art problems and that is economically advantageous for the purchaser.
  • the device will be advantageously versatile in the direction of air flows and in the choice of air flows to be delivered or not.
  • the device will be versatile and useful for the patient, the operator and for the general sanitation/management of the dental surgical field, the management of instruments and equipment in general in this sector. Furthermore, it is intended to provide the dentist with an aid that is not bulky, versatile and immediate to use.
  • One purpose of this invention is to describe a device that can reduce the psychophysical discomfort of patients during dental sessions.
  • Another purpose is to facilitate dentists in treating patients with difficulty to endure dental care.
  • it must be connected by means of articulated arms, for example, to the frame of a united group and characterized by the fact that it comprises at least one source of forced air suitable for directing a jet of forced air in a direction substantially parallel to the beam of light emitted by the lamp itself.
  • said jet of forced air is suitable to reach the face and/or other parts of the patient's body.
  • This air source can be fed by any means suitable for the purpose and convey simple ambient air or treated air as better explained below.
  • the air jet can be directed by means of special adjustable nozzles that in some forms of realization can also be extensible or placed in any part of the lamp.
  • these nozzles may also be equipped with variable opening shutters located in the nozzles themselves. These shutters can be opened manually (mechanical opening and adjustment wheel or similar) or by means of known electronic controls connected there (remote control or similar).
  • the innovative lamp particularly suitable for dental units comprises at least one moving or fixed head according to what is already present in known art but it will be further and innovatively equipped with one or more sources of forced air advantageously directionable and modular according to the forms of realization: it has been noted in fact that very often the patient in care on the chair requires air, obtaining psychological benefit in perceiving a "wavering" on the body and in particular on the face, this probably because the air in the face may represent an element of distraction and/or suggest a greater sense of freedom or however evoke more tranquilizing thoughts, this probably because the air in the face may represent an element of distraction and/or suggest a greater sense of freedom.
  • this lamp suitable for dental units will also innovatively comprise one or more sources of forced air to be directed to the face of the patient; this forced air will be supplied through one or more nozzles powered by means suitable for the purpose such as a fan connected to a motor. These means being positioned in any position either on the dental unit or in any other position.
  • the flow of this forced air can be activated by means of a dedicated control preferably on the dental unit itself and can still be adjusted in its intensity by means of a special regulator.
  • this air source comprises, in some variants, at least one dispenser for ambient air and/or comprises at least one oxygen enrichment placed in or near the lamp to supply treated air with added fragrances or enriched oxygen and/or comprises at least one air-conditioning unit to supply hot and/or fresh air.
  • Figure 1 shows an example of the innovative ventilating lamp for units groups.
  • Lamp 1 here is bound to the unit (not shown here for simplicity) by means of arm 2.
  • the head of lamp 4 can be equipped with handles 3 for the movement of lamp 1, on this body there are one or more light sources 5 and innovatively also at least one source 10 for the supply of forced air, including at least one or more nozzles 6 for the output of forced air.
  • These nozzles 6 can be of swivel type or fixed and can be placed indifferently either in the head of the lamp 4 or in another position as long as it is suitable to ventilate the patient, for example, even when it is illuminated in the face during dental treatments.
  • Nozzles 6 can be powered, for example, by a motorized fan comprised in the source 10 which can be placed either directly on lamp 1 or in another position; in this case there will be ducts capable of transferring the forced air from the source to the outlet of said nozzles 6.
  • the air inlets can simply flow from the room but, in other forms of realization, it will be possible, for example, to enrich the air with oxygen or fragrances that can make it even more effective (depending on the patient) the effect of said forced air (detailed description with below).
  • these nozzles can orient the direction of flow by choosing whether to direct all the forced air on the illuminated part of the face or also extend the range of action of this air for example on the upper part of the face and/or other parts of the body, making the effect of the air on the patient's body even more customizable.
  • the patient despite being subjected to constriction in the dental unit chair, can benefit from a relief induced by the air blown by the innovative lamp 1, particularly suitable for dental units, thus resolving the problems illustrated above in a completely new way.
  • a further possibility will be that of also being able to regulate the outlet temperature of said air flow so as to enrich the personalization of the treatment.
  • the lamp 1 is arranged to illuminate the area to be treated by means of a light source 5 while the nozzles 6 are automatically in a position to effectively ventilate with a jet of air 21 the face of the patient, thus determining the benefit as indicated above.
  • a light source 5 which comprises at least one fan with motor 22 suitable to produce forced air to be directed to a duct 23 up to the outlet of the nozzles 6.
  • This forced air can be adjusted in intensity by acting for example both on the power supplied to the engine 22 and on the arrangement of the nozzles 6, the temperature can still be adjusted for example by providing an air conditioning unit 18 and can finally be modulated as to the fragrance by means of essences dispersed in the flow of air sent to the nozzles 6.
  • Said source 10 therefore comprises at least one ambient air supply and/or comprises at least one oxygen enrichment device 25 placed in or near lamp 1 to supply treated air with added fragrance or oxygen-enriched air and/or comprises at least one air-conditioning unit 18 to supply hot and/or fresh air.
  • said lamp can comprise in addition or alternative extensible nozzles, i.e. nozzles connected to arms (tubes type extensible appendages) that can advantageously be directed with greater precision in a particular area where the patient wishes to be ventilated, for example, a nozzle could also be turned towards the forehead of the dentist that in case of particularly long and complex operations could in turn benefit from this opportunity.
  • extensible nozzles i.e. nozzles connected to arms (tubes type extensible appendages) that can advantageously be directed with greater precision in a particular area where the patient wishes to be ventilated, for example, a nozzle could also be turned towards the forehead of the dentist that in case of particularly long and complex operations could in turn benefit from this opportunity.
  • the forced air source 10 comprises electrical means configured to move said fins 16 of said nozzles also with continuous wave motion.
  • variable opening shutters placed in the nozzles themselves can be provided.
  • said forced air source comprises means of activation attached to this lamp such as at least one switch 19 and/or means of remote control such as at least one remote control 29.
  • said ventilating lamp 1, and in particular the elements of source 10 of forced air can comprise means of reception for wireless signals to be able to adjust the various functions as mentioned also by means of remote control means.
  • At least one of said nozzles is capable of emitting a laminar air flow to sanitize the objects/environment to which it is directed, so that this source of forced air including means for adjusting the speed of the air flow emitted by/from the nozzles, so as to regulate the delivery from turbulent flow to laminar and vice versa.
  • this adjustment will be available for one or more vents, not necessarily for all vents, and in any case the air flow delivery speed can be adjusted individually for each vents, so in this case the main source of forced air can be divided into several individually adjustable micro-sources.
  • the nozzles of the diffusers suitable for delivering air as a unidirectional laminar flow and possibly suitable filters for the purpose, said nozzle(s) diffusing a laminar air flow directed in a single direction, or unidirectional: air is delivered at a given speed and passes through a special filter placed before the outlet of the nozzle itself. This will happen when the relative nozzle is set to the "laminar flow" function that can be set by suitable adjustment means.
  • Said lamp therefore still comprises at least means for adjusting the flow rate, such as appropriate speed controls, which can be analog or digital of any kind suitable for the purpose (e.g. adjustment knobs, trims, buttons, electronic displays, etc.).
  • appropriate speed controls can be analog or digital of any kind suitable for the purpose (e.g. adjustment knobs, trims, buttons, electronic displays, etc.).
  • the directional fins can be removed, which can be easily made as an additional piece to be stuck and removed in the nozzle if necessary.
  • air is taken from the environment and is substantially sanitized before being directed where the operator considers it most necessary, this being initially taken from the environment and then channeled into the forced air source which, by channeling the air towards the relative nozzle regulated on "laminar flow", purifies the flow itself, regulating its speed and introducing it into the environment after being passed through one or more filter(s) (already described), this being defined here for the present invention: "laminar flow regulation”.
  • Said vents essentially treat the air to be pushed at low forward speed (from 0.3 to 0.7m/s typically) and purified with filters preferably for example HEPA (High Efficiency Particulate Air) that reduce by 99% the bacterial load in the air, or mini-pleat filters for unidirectional flows DELTA, HEPA H14 and ULPA U15 series, which are suitable for use in all systems where a very high air purity is required.
  • filters preferably for example HEPA (High Efficiency Particulate Air) that reduce by 99% the bacterial load in the air, or mini-pleat filters for unidirectional flows DELTA, HEPA H14 and ULPA U15 series, which are suitable for use in all systems where a very high air purity is required.
  • each nozzle individually, for example a nozzle to be directed on the dental tray can be adjusted to laminar flow and/or an additional nozzle directed towards the glass in the rinsing area can be adjusted to laminar flow, and a nozzle directed towards the patient's face or body to refresh it can be set to fresh/hot air with a regular flow. Any other adjustment will be properly possible, such as the direction of laminar flow towards the patient's face to protect him from microbiological and/or other bacterial contamination.
  • the lamp can be kept on at night in an advantageous way to better sanitize the environment.
  • the air supplied by the innovative ventilating lamp can also be supplied by the compressor that supplies the dental unit, obviously making the appropriate modifications and additions to this compressor, but in a considerably advantageous way since it is not needed to add a special additional source of forced air 10, but by using, modifying and integrating it appropriately, the air source of the compressor already present in a dental unit, with a considerable reduction in the overall size of the innovative ventilating lamp for dental units innovatively described in this invention.
  • the compressor in this form of construction acts as a forced air source 10.
  • nozzles can be adjusted with different flow rates, and with different temperatures, by virtue of special regulators and means suitable for the purpose inserted in the source of forced air and/or the like.
