Description

[0001] PLASMA DEVICE FOR DISINFECTION

[0002] Technical Field

[0003] The present invention relates to a plasma device for disinfection.

[0004] Background Art

[0005] A number of devices are known to achieve a disinfectant effect through plasma generation.

[0006] Generally, to generate plasma, the devices of known type employ a gas that is ionized through a special electrode inducing the change of state from gas to plasma.

[0007] Specifically, ionization occurs by means of an electric field that is generated between the electrode (properly polarized) and the body to be disinfected itself, that is, through the potential difference between the latter.

[0008] The plasma obtained in this way is then dispensed to the body to be disinfected through a special nozzle placed in the proximity of the electrode.

[0009] In this way, it is sufficient to bring the nozzle and the corresponding electrode close to the body to be disinfected to generate the plasma.

[0010] This type of device does, however, have some drawbacks.

[0011] In fact, the potential of the body to be disinfected is variable depending on various parameters, such as environmental parameters, technical parameters peculiar to the same body to be disinfected and / or similar parameters.

[0012] In addition, the characteristics of the electric field are strictly dependent on the distance between the electrode and the body to be disinfected.

[0013] Therefore, the characteristics of the electric field which is generated between the electrode and the body to be disinfected are significantly affected by the potential of the body itself and by its distance from the electrode.

[0014] These drawbacks make ionization and plasma generation very unstable and, in addition, risk damaging the device and / or the body to be disinfected, e.g., due to electrical discharge or other undesirable phenomena.

[0015] Therefore, the devices of known type prove to be inefficient and unsafe.

[0016] Description of the Invention

[0017] The main aim of the present invention is to devise a device for disinfection which makes plasma generation more stable than the devices of known type.

[0018] A further object of the present invention is to devise a device for disinfection which can be used more safely than the devices of known type.

[0019] Another object of the present invention is to devise a device for disinfection which allows the aforementioned drawbacks of the prior art to be overcome within the framework of a simple, rational, easy and effective to use as well as inexpensive solution.

[0020] The aforementioned objects are achieved by this device having the characteristics of claim 1.

[0021] The aforementioned objects are achieved by this method having the characteristics of claim 13.

[0022] The aforementioned objects are achieved by this kit having the characteristics of claim 14.

[0028] Figures 4 and 5 are schematic views of the kit according to the invention. Embodiments of the Invention

[0029] With particular reference to these figures, reference numeral 1 globally denotes a plasma device for disinfection.

[0030] The plasma device 1 for disinfection comprises: at least one adduction port 2 of a gas to be ionized for plasma generation; at least one plasma delivery port 3 provided with at least two electrodes 4 configured to ionize the gas coming from the adduction port 2.

[0031] Conveniently, the gas to be ionized is of the type of an inert gas, such as helium or argon. Preferably, the delivery port 3, in use, is arranged facing a body to be disinfected 27, e.g. an eye.

[0032] Specifically, the delivery port 3 defines an outlet stretch 5 through which plasma is delivered outside the same delivery port.

[0033] Preferably, the outlet stretch 5 has a substantially circular conformation.

[0034] According to the invention, the device 1 comprises at least one duct 6 connecting the adduction port 2 to the delivery port 3 in a fluid-operated maimer.

[0035] Preferably, the duct 6 has a substantially cylindrical and preferably straight conformation.

[0036] According to the invention, the device 1 comprises at least one radio-frequency signal electric generator 7 electrically connected to the electrodes 4 and activatable to apply to the latter a potential difference variable over time with a working frequency and which generates between the electrodes themselves an electric field intercepting the gas coming from the adduction port 2, thus ionizing it.

[0037] Specifically, one of the electrodes 4 is connected to a ground or earth reference potential.

[0038] Preferably, the electrode 4 arranged more in the proximity of the plasma outlet, e.g., more in the proximity of the outlet stretch 5 is connected to the ground reference potential.

[0039] Usefully, each of the electrodes 4 comprises at least one grid 8.

[0040] Preferably, the term grid 8 also means a generic perforated body which allows the gas to flow through.

[0041] Specifically, the grids 8 are arranged facing and spaced apart from each other to define between them an ionization region 9 within which the electric field propagates.

[0042] In even more detail, the electric field generated between the electrodes 4 is substantially zero outside the ionization region 9.

[0043] This expedient allows securing the body to be disinfected 27.

[0044] Conveniently, the delivery port 3 has no dielectric barrier means arranged within said ionization region 9. In particular, the ionization region 9 extends substantially unobstructed between the electrodes 4.

[0045] Preferably, the grids 8 have a substantially circular conformation.

[0046] Appropriately, the ionization region 9 and / or the slits of the grids 8 communicate with the duct 6, so as to receive the gas flowing through the latter.

[0047] In this way, the grids 8 intercept the flow of gas which thus flows through them, so that it is subjected to the ionization induced by the electric field.

[0048] Specifically, the gas coming from the adduction port 2 flows through the ionization region 9, where it is at least partly ionized, and subsequently flows outside in the form of a flow of gas enriched in Reactive Oxygen and Nitrogen Species (RONS), which is used for disinfection purposes.

[0049] In the context of this disclosure, the term “plasma” is intended to refer both to the ionized gas present within the ionization region and to the RONS -enriched flow of gas coming out of the delivery port 3.

[0050] Preferably, the delivery port 3 defines an ionization stretch 10 which receives, at inlet, the gas coming from the duct 6 through one of the grids 8 and which delivers, at outlet, the plasma through the other of the grids 8.

[0051] Usefully, the duct 6 defines a conveyance direction 11 of the gas substantially transverse, preferably orthogonal, to the grids 8.

[0052] Preferably, the duct 6 and / or the delivery port 3 define an obligatory gas path through the grids 8 and / or the ionization stretch 10.

[0053] Conveniently, the device 1 comprises at least a first and a second electrically conductive body 12, 13 extending along the duct 6.

[0054] Preferably, the first and the second conductive bodies 12, 13 extend substantially parallel to each other.

[0055] In addition, each of the conductive bodies 12, 13 is connected between a corresponding electrode 4 and the generator 7, electrically connecting them to each other.

[0056] In addition, the first conductive body 12 is arranged within the duct 6 and occupies the center thereof.

[0057] Specifically, the first conductive body 12 is connected to the center of one of the grids 8.

[0058] In more detail, the first conductive body 12 is connected to the center of the first grid 8 which receives the gas coming from the duct 6.

[0059] Appropriately, the duct 6 defines an inlet stretch 14 of the gas within the delivery port 3.

[0060] In addition, the grid 8 of the electrode 4 connected to the first conductive body

[0061] 12 occupies, preferably completely, the inlet stretch 14.

[0062] Advantageously, the second conductive body 13 surrounds, at least partly, the first conductive body 12.

[0063] In particular, the second conductive body 13 has a substantially tubular conformation.

[0064] Preferably, the second conductive body 13 defines the outlet stretch 5 of the plasma outside the delivery port 3.

[0065] In particular, the grid of the electrode 4 connected to the second conductive body

[0066] 13 occupies, preferably completely, the outlet stretch 5.

[0067] In particular, the second conductive body 13 is connected to the perimeter of one of the grids 8.

[0068] Advantageously, the device 1 comprises at least a first electrically insulating body 15 surrounding the first conductive body 12, facing the inside of the duct 6.

[0069] Specifically, the first insulating body 15 contains within it the first conductive body 12, substantially covering it.

[0070] Preferably, the first insulating body 15 has a substantially cylindrical conformation.

[0071] Advantageously, one end of the first insulating body 15 substantially abuts against the grid 8 connected to the first conductive body 12.

[0072] In addition, the device 1 comprises at least a second insulating electric body 16 lining the second conductive body 13, facing the inside of the duct 6 substantially facing the first insulating body 15.

[0073] Specifically, the second insulating body 16 surrounds the first insulating body 15. In more detail, the insulating bodies 15, 16 extend substantially parallel to each other. In other words, the distance between the insulating bodies 15, 16 defines the gas flowing stretch within the duct 6.

[0074] In fact, it cannot be ruled out that the duct 6 may be defined by the insulating bodies 15, 16 and / or by the conductive bodies 12, 13.

[0075] Conveniently, the device 1 comprises electrically connected impedance matching means 17, 18 between the generator 7 and the electrodes 4 and provided with: at least one inductive loading element 17 having a predefined inductive reactance adapted to match the impedance of the generator 7; and / or at least one capacitive loading element 18 having a predefined capacitive reactance adapted to match the impedance of the generator 7.

[0076] In other words, the inductive reactance and / or capacitive reactance combined, as known, with the generator impedance makes an equivalent generator impedance substantially equal to the conjugate complex of the load impedance.

[0077] Preferably, the term “load” means the electronic components electrically connected upstream of the adaptive means 17, 18, e.g. the electrodes 4 and / or the conductive bodies 12, 13.

[0078] In this way, the adaptive means 17, 18 allow maximum power transfer between the generator 7 and the load.

[0079] Advantageously, the device 1 comprises a connecting cable 19 of the generator 7 to the electrodes 4.

[0080] Specifically, the connecting cable 19 coincides with the capacitive loading element 18.

[0081] In more detail, the connecting cable 19 connects the generator 7 to the conductive bodies 12, 13.

[0082] Appropriately, the connecting cable 19 has a predefined length that defines, possibly together with the other characteristics of the cable itself, its capacitive reactance value.

[0083] Preferably, the connecting cable 19 is a coaxial cable.

[0084] Conveniently, the device 1 comprises gas adduction means 20 connected to the adduction port 2 and activatable to feed, through the latter, the gas within the duct Preferably, the adduction means 20 are connected to the adduction port 2 in a fluid-operated maimer via a preferably flexible pipeline 20a.

[0085] In addition, the device 1 comprises control means 21 configured to: command the adduction means 20, by activating and / or deactivating them, to allow and / or prevent the feeding of gas within the duct 6, respectively; command the generator 7, by activating and / or deactivating it, to allow and / or prevent the application of the potential difference between the electrodes 4, respectively; command the device 1 between at least one calibration configuration, wherein the adduction means 20 are deactivated and the generator 7 is activated, and at least one working configuration, wherein the adduction means 20 are activated and the generator 7 is activated.

[0086] Preferably, the control means 21 are configured to command the device 1 between the calibration configuration, the working configuration and an intermediate configuration, wherein the adduction means 20 are activated and the generator 7 is deactivated.

[0087] Advantageously, the device 1 comprises: electrically connected detection means 22 between the generator 7 and the electrodes 4 and configured to substantially detect the potential difference applied to the electrodes 4; and / or electrically connected measurement means 31 between the generator 7 and the electrodes 4 and configured to detect the working frequency.

[0088] Preferably, the detection means 22 comprise a capacitive divider and a diode.

[0089] In addition: the control means 21 are operationally connected to the detection means 22 and / or to the measurement means 31 and are configured to vary and / or set the working frequency; in the calibration configuration, the control means 21 are configured to:

[0090] - vary the working frequency over time; - detect (preferably via the detection means 22) the maximum value reached by the potential difference during the variation in such a working frequency;

[0091] - detect (preferably via the measurement means 31) the working frequency value corresponding to such maximum detected value reached by the potential difference.

[0092] Specifically, the control means 21 are configured to vary the working frequency over time between a first and a second predefined frequency value.

[0093] In more detail, the control means 21 are configured to process an optimal working frequency value depending on the working frequency value corresponding to the maximum detected value (via the detection means 22) reached by the potential difference.

[0094] This value, in particular, is a higher frequency value than the working frequency value corresponding to the maximum detected value reached by the potential difference.

[0095] Conveniently, in the working configuration, the control means 21 are configured to set the working frequency value to the optimal working frequency value.

[0096] Specifically, in the working configuration, the control means 21 are configured to: increase the working frequency value when they detect a potential difference value less than a critical potential difference value; and / or deactivate the generator 7 when they detect a potential difference value less than a critical potential difference value and / or when the potential difference value remains less than the critical potential difference value as a result of the increase in the working frequency value.

[0097] Preferably, the critical potential difference value is a value processed depending on the potential difference value corresponding to the optimal working frequency value.

[0098] For example, the critical potential difference value is a percentage of potential difference value corresponding to the optimal working frequency value.

[0099] Thus, the increase in the working frequency value (or optimal working frequency) allows the potential difference value to increase.

[0100] However, the control means 21 are configured to deactivate the generator 7 in case such potential difference value remains below the critical potential difference value.

[0101] It cannot, however, be ruled out that the control means 21 may be configured to deactivate the generator 7 without increasing the working frequency value.

[0102] Advantageously, the device 1 comprises: power supply means 23 configured to electrically supply the generator 7 with at least one current and one power supply voltage; electrically connected verification means 30 between the control means 21 and the generator 7 and configured to detect at least one of either the current or the power supply voltage.

[0103] Conveniently, the power supply voltage is substantially less than or equal to 1.4 kV and / or substantially greater than or equal to 0.7 kV.

[0104] In particular, such a power supply voltage value allows the device to be used safely, significantly reducing, substantially to zero, the risk of electrical discharge towards the same body to be disinfected 27.

[0105] In fact, under standard conditions, at atmospheric pressure, the dielectric strength of air is about 3 kV / mm. Consequently, the risk of electrical discharge triggering substantially occurs only when the distance between the electrodes 4 and the body to be disinfected 27 is substantially less than 0.5 millimeters.

[0106] Usefully, such a risk is completely zeroed by the spacer body 24 (introduced later in this disclosure) which keeps the electrodes 4 at a safe distance, preferably greater than 0.5 mm, from the body to be disinfected 27.

[0107] These expedients allow the device 1 to place the electrodes 4 at a close distance, e.g. less than or equal to 1 or 2 mm, thus improving the effectiveness of the disinfectant treatment.

[0108] Therefore, unlike known devices operating at significantly higher voltages, e.g. even on the order of 10 kV, the device 1 is particularly suitable for close and localized disinfection operations, such as eye disinfection.

[0109] In addition, the control means 21 are operationally connected to the power supply means 23 and / or to the verification means 30 and are configured to: reduce the current and / or power supply voltage value when they detect a potential difference value less than a reference potential difference value; and / or deactivate the generator 7 when they detect a potential difference value less than a reference potential difference value and / or when the potential difference value remains less than the reference potential difference value as a result of the reduction in the current and / or power supply voltage value.

[0110] Preferably, the reference potential difference value is a value processed depending on the potential difference value corresponding to the optimal working frequency value.

[0111] For example, the reference potential difference value is a percentage of the potential difference value corresponding to the optimal working frequency value. In this way, the reduction in the current and / or power supply voltage value allows the potential difference value to increase.

[0112] However, the control means 21 are configured to deactivate the generator 7 in case this potential difference value remains lower than the reference potential difference value.

[0113] It cannot, however, be ruled out that the control means 21 may be configured to deactivate the generator 7 without increasing the current and / or power supply voltage value.

[0114] Preferably, the reference potential difference value and the critical potential difference value coincide.

[0115] Conveniently, at least one of the adduction port 2, the delivery port 3 and the duct 6 are mounted on a base structure 32, preferably manually movable by an operator.

[0116] Specifically, the base structure 32 comprises at least one handle 34 adapted to allow an operator to manually move the base structure.

[0117] Usefully, the control means 21 are configured to command (in one or more of the ways described above) at least one of the adduction means 20, the verification means 30, the generator 7, the measurement means 31 and the detection means 22 by means of one or more command lines 35 (e.g., electrical links) connecting the control means 21 to one or more of the means listed above.

[0118] Appropriately, the connecting cable 19 connects the base structure 32 to the generator 7, thus enabling the movement of the base structure 32 with respect to the generator 7.

[0119] Similarly, the pipeline 20 also connects the base structure 32 to the adduction means 20, thus enabling the movement of the base structure 32 with respect to the adduction means 20.

[0120] Conveniently, the base structure 32 comprises at least one manual actuating body 33 such as a button, a trigger or the like to command the device 1 in the working configuration.

[0121] Preferably, the base structure 32 has a substantially gun conformation, wherein the duct 6 substantially defines the gun barrel.

[0122] Advantageously, the device 1 comprises a supporting frame 25 arranged, in use, on a stable resting surface and provided with a hooking portion 26 to which the base structure is couplable in a removable maimer.

[0124] Preferably, one or more of the characteristics of the device 1 described above are also meant to apply to the device 1 which has been described with reference to the method of using the device itself.

[0125] Conveniently, the method involves carrying out at least one phase of calibration prior to the phase of use.

[0126] In even more detail, the method involves carrying out at least one phase of calibration prior to each phase of use.

[0127] Conveniently, the method comprises at least a preliminary phase of use wherein the device 1 is commanded in the intermediate configuration. In particular, the method involves carrying out at least one intermediate phase between the calibration phase and the use phase.

[0128] Preferably, steps or phases comprised by the method of using the device 1 are meant to be one or more of the operations carried out by one or more of the components of the device 1 and are generally anticipated in this disclosure by the term “configured to” or equivalent terms. Such phases or steps are preferably, but not necessarily, carried out by the same components involved and / or by the system 1 for carrying out the process itself.

[0129] According to a further aspect, the present invention relates to a kit 1, 24 for disinfection, comprising: at least one device 1; at least one spacer body 24 couplable, in a removable maimer, to the delivery port 3, the spacer body 24, in use, extending, by a predefined distance D, frontally cantilevered from the delivery port 3, so as to hinder the approach of the latter to a body to be disinfected 27 beyond the predefined distance D. Preferably, one or more of the characteristics of the device 1 and / or of the method of use of the latter described above are also meant to apply to the device 1 described with reference to the kit 1, 24.

[0130] It cannot, however, be ruled out that the device 1 may comprise a spacer body 24 rigidly associated with the delivery port 3.

[0131] Advantageously, the kit 1, 24 comprises a plurality of spacer bodies 24.

[0132] In addition: one or more of the spacer bodies 24 have different dimensions from each other extending, in use, frontally cantilevered from the delivery port 3 by different predefined distances D; and / or a plurality of spacer bodies 24, each comprising at least one identifying element 28 of the identification code that uniquely identifies the corresponding spacer body 24; the device 1 comprises identification means 29 configured to detect the identifying elements 28 and to acquire the corresponding identification codes; the control means 21 are configured to allow / prevent the activation of the device 1 depending on the identification code.

[0134] Preferably, the identifying elements 28 are RFID-type identifying elements and the identification means 29 are of the type of an RFID reader.

[0135] It has in practice been ascertained that the described invention achieves the intended objects.

[0136] In particular, the fact is emphasized that the pair of electrodes allows the plasma to be generated in a very stable maimer. In addition, the pair of electrodes allows the device to be used more safely than the devices of known type.

[0137] The control means and / or the spacer body also contribute to the safe use of the device.
