[0030] DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0031] Figures 1 to 4 show a distribution device 100 similar to that described and protected in patent WO2019186072 belonging to the applicant.

The dispensing device 100 can be used in different fields and more particularly in the medical field such as dental, orthopedics, aesthetics, ophthalmology and veterinary.

The dispensing device 100 comprises an elongated body 200 comprising a control button 300, a control button 400 and a withdrawal button 500 allowing the user U to select an operating mode previously recorded in an electronic card of control not illustrated housed in said distribution device.

[0034] The dispensing device 100 comprises at one of its ends and more particularly opposite the withdrawal button 500 a housing 110 allowing the attachment of a connection tip coming from a range of tips A to G.

[0035] The connection ends A to G respectively allow different interventions to be carried out, namely:

I. Connection tip A allows injection of dental anesthetic;

II. The connection tip B allows the filling and distribution of any type of liquid such as disinfectant for cleaning dental canals during devitalization;

III. The G connection tip allows the distribution of fluid resulting from powder/liquid mixture capsules;

IV. The connection tip D allows the application of so-called “small capsules” capsules containing more or less viscous pastes;

V. The connection tip E allows the application of soft paste as for dental impression molding; VI. The connection tip F allows the application of any type of more or less viscous paste pre-filled industrially, such as a dental composite;

VII. The double syringe type G connection tip allows the application of two pastes of all types, mixed through a mixer;

[0036] The distribution device 100 comprises in its internal part and as described in patent WO2019186072 belonging to the applicant recognition means making it possible to initialize a control program corresponding to the chosen end piece A to G, an electric motor driving a thrust piston allowing action on the previously fixed tip.

[0037] The distribution device 100 can be positioned on a charging support 600 making it possible to charge the batteries provided inside said device, said batteries allowing for example the driving of the electric motor, the power supply of the electronic card of control and recognition means making it possible to initialize a control program corresponding to the chosen tip.

[0038] In our example described below, the modes and sub-modes of the control program are those proposed in the dental field.

Obviously and without limiting the scope of the invention, these modes and sub-modes can be applied to other fields, such as for example but in a non-limiting manner the medical fields as already indicated previously.

[0040] Figures 5 and 13 illustrate a diagram and a flowchart showing the different stages of the distribution method according to the present invention for the implementation by a user U of the distribution device 100.

The first step AND 1 consists of the user U being able to take the distribution device 100 from its recharging support 600 or anywhere the latter may be located.

The second step ET2 allows, depending on the act to be carried out, the user U to choose a connection tip in the range of tips A to G, each of which has a previously defined function.

The third step ET3 allows the user U to install and immobilize the connection tip chosen from the tip range A to G inside the distribution device 100. When the connection tip is fixed inside the distribution device 100, the latter makes it possible to activate recognition means housed in said distribution device. The mechanical or electronic type recognition means make it possible to initialize a control program loaded into the electronic control card and corresponding to the chosen tip A to G. The control program checks whether the chosen end piece A to G presents different mode and/or sub-mode of operation according to step A1, Figure 13.

The fourth step ET4 allows the user U, when the control program is initialized, to select if this is necessary depending on the connection end A to G and by means of at least one button. 300 commands a particular mode of operation among the different modes proposed by the control program.

The fifth step ET5 consists of the user U positioning the dispensing device 100 in the working zone in which the nozzle A to G must be located. In our non-limiting embodiment the user U for example, places the previously selected tip in the mouth of a patient P in order to carry out the treatment necessary for the desired sequence of care (infiltration, irrigation, placement of reconstruction material, placement of impression paste, etc.).

The sixth step ET6 allows the user U to activate a control button 400 in order to allow the automatic advancement of a thrust piston driven by an electric motor housed inside the distribution device 100 until 'to its initial position according to the previously determined control program.

[0047] According to the seventh step ET7, the user U keeps pressed the control button 400 making it possible to launch the control program according to the previously determined functions, to drive the thrust piston housed in the distribution device 100 in order to act on the tip A to G and the distribution of said product.

[0048] According to the eighth step ET8, the user U double clicks and holds down the control button 400 making it possible to launch the control program according to the previously determined functions, to drive the thrust piston housed in the distribution device 100 in order to to act on the tip A to G and the distribution of said product.

[0049] According to the ninth step ET9, the user U keeps pressed the withdrawal button 500 making it possible to launch the control program according to the previously determined functions, to drive the thrust piston housed in the distribution device 100 in order to act on tip B.

[0050] According to the tenth step ET10, the user U double clicks the withdrawal button 500 making it possible to launch the control program according to the previously determined functions, to drive the thrust piston housed in the distribution device 100 in order to act on the tip B. During this step the user U must check whether the treatment is completed according to A2 and proceed to the next steps. If this is not the case, it can return to the end of step ET6.

[0051] The eleventh step AND 11 consists of the user U releasing the control button 400 at the end of the application of the product contained in the tip A to G. During this step the user U must check if the treatment is completed according to A2 and proceed to the next steps. If this is not the case, it can return to the end of step ET6.

[0052] The twelfth step ET12 consists of the user U releasing the withdrawal button 500 at the end of suction of the product into the nozzle B. During this step the user U must check whether the treatment is completed according to A2 and proceed to the next steps. If this is not the case, it can return to the end of step ET6.

[0053] During the thirteenth step ET13 the user U double clicks a withdrawal button 500 making it possible to control the electric motor causing the withdrawal of the thrust piston of the distribution device 100 out of the nozzle.

[0054] During the fourteenth step ET14 the user U activates a withdrawal button 500 making it possible to control the electric motor causing the withdrawal of the thrust piston of the distribution device 100 from the nozzle.

[0055] During the fifteenth step ET 15 the user U removes the chosen tip A to G from the dispensing device 100.

[0056] The user U then proceeds to the verification steps according to A3 for, depending on the tip A to G used, either store it for sterilization step ET 16, or throw it away step ET 17.

[0057] In Figure 6 the different operating modes of the distribution process are shown when the user U connects a type A connection end to the distribution device 100.

[0058] When the user U chooses a connection tip A and the latter is fixed inside the distribution device 100, the recognition means are automatically activated making it possible to initialize a control program corresponding to the chosen tip .

[0059] Thus the user U can, by means of the control button 400, select one of the following proposed modes in the control program:

I.MA1

II. MA2

III. MA3 [0060] In our example, namely the dental domain, the MA1 mode corresponds to a so-called “infiltration” mode. In this mode the user U can choose one of the following sub-modes:

• MA10 - this submode corresponds to the approach of the thrust piston of the distribution device 100 connected to the connection end A at a constant speed Va10;

• MA1 1 - this submode corresponds to the application to the thrust piston of the distribution device 100 connected to the connection end A of a constant low speed Va11, then progressive from a speed Va11 to a high speed Va12 constant;

• MA12 - this submode corresponds to the application to the thrust piston of the distribution device 100 connected to the connection end A of a constant high speed Va12;

• MA13 - this submode corresponds to the withdrawal of the thrust piston from the distribution device 100 at a constant speed Vr.

[0061] The MA2 mode corresponds in the dental field to a so-called “intraligamentous” mode. In this mode, user U can choose one of the following sub-modes:

• MA20 - this submode corresponds to the approach of the thrust piston of the distribution device 100 connected to the connection end A at a constant speed Va17;

• MA21 - this submode corresponds to the application to the thrust piston of the distribution device 100 connected to the connection end A of a constant low speed Va13, then progressive from a low speed Va13 to a high speed Va14 constant;

• MA22 - this submode corresponds to the application to the thrust piston of the distribution device 100 connected to the connection end A of a constant high speed Va14;

• MA23 - this submode corresponds to the withdrawal of the thrust piston from the distribution device 100 at a constant speed Vr.

[0062] The MA3 mode corresponds in the dental field to a so-called “truncular” mode. In this mode, user U can choose one of the following sub-modes:

MA30 - this submode corresponds to the approach of the thrust piston of the distribution device 100 connected to the connection end A at a constant speed Va18; • MA31 - this submode corresponds to the application to the thrust piston of the distribution device 100 connected to the connection end A of a constant low speed Va15, then progressive from a low speed Va15 to a constant high speed Va16 ;

• MA32 - this submode corresponds to the application to the thrust piston of the distribution device 100 connected to the connection end A of a constant high speed Va16;

• MA33 - this submode corresponds to the withdrawal of the thrust piston from the distribution device at a constant speed Vr.

• MA34 - this submode corresponds to partial removal of the thrust piston from the distribution device.

[0063] Note that the speeds Va10 to Va18 of each sub-mode are between 0.05 millimeters per second and 15 millimeters per second. The constant speed Vr is between 0.05 millimeters per second and 15 millimeters per second.

[0064] In Figure 7 the different operating modes of the distribution process are shown when the user II connects a type B connection end to the distribution device 100.

[0065] When the user U chooses a connection tip B and the latter is fixed inside the distribution device 100, the recognition means are automatically activated making it possible to initialize a control program corresponding to the chosen tip .

[0066] Firstly, the user activates the retraction button 500 making it possible to suck up a product contained in an external bottle in order to fill the type B tip.

[0067] Then the user U can, by means of the control button 400, select one of the following proposed modes in the control program:

I.MB1

II. MB2

III. MB3

[0068] In our example, namely the dental domain, the MB1 mode corresponds to a so-called “irrigation” mode of the control program. In this mode the user U can choose one of the following sub-modes: • MB10 - this submode corresponds to the approach of the thrust piston of the distribution device 100 connected to the connection end B at a constant speed Vb10;

• MB11 - this submode corresponds to the application to the thrust piston of the distribution device 100 connected to the connection end B of a constant low speed Vb11;

• MB12 - this submode corresponds to the application to the thrust piston of the distribution device 100 connected to the connection end B of a constant high speed Vb12;

• MB13 - this submode corresponds to the withdrawal of the thrust piston from the distribution device at a constant speed Vr.

[0069] The MB2 mode corresponds in the dental field to a so-called “purge” mode of the control program. This mode allows the user U to be able to choose one of the following sub-modes:

• MB20 - this submode corresponds to the approach of the thrust piston of the distribution device 100 connected to the connection end B at a constant speed Vb16;

• MB21 - this submode corresponds to the application to the thrust piston of the distribution device 100 connected to the connection end B of a constant low speed Vb13;

• MB22 - this sub-mode corresponds to the application to the thrust piston of the distribution device 100 connected to the connection end B of a constant high speed Vb14;

• MB23 - this submode corresponds to the withdrawal of the thrust piston from the distribution device at a constant speed Vr.

[0070] The MB3 mode corresponds in the dental field to a so-called “pump” mode of the control program. This mode allows the user to choose one of the following sub-modes:

• MB31 - this submode corresponds to the application to the thrust piston of the distribution device 100 connected to the connection end B of a constant low speed Vb15;

• MB32 - this submode corresponds to the removal of the thrust piston from the constant speed distribution device Vr. [0071] Note that the speeds Vb10 to Vb16 of each sub-mode are between 0.05 millimeters per second and 15 millimeters per second. The constant speed Vr is between 0.05 millimeters per second and 15 millimeters per second.

[0072] We have shown in Figures 8, 10 to 12 the different operating modes of the distribution process when the distribution device 100 is connected with a connection end of type C or type E or type F or type G .

[0073] When the user U chooses a connection tip C, E, F or G and the latter is fixed inside the distribution device 100, the recognition means are automatically activated, making it possible to initialize a control program corresponding to the chosen tip.

[0074] Thus the user U can, by means of the control button 400, select in the control program one of the modes MC1, ME1, MF1 or MG1 depending on the tip chosen and allowing access to one of the following submodes:

• MC10, ME10, MF10 or MG10 - this submode corresponds to the approach of the thrust piston of the distribution device 100 connected to the connection end C, E, F or G at a speed Vc10, Ve10, Vf 10, Vg10 constant;

• MC1 1, ME1 1, MF11 or MG1 1 - this submode corresponds to the application to the thrust piston of the distribution device 100 connected to the connection end C, E, F or G of a low speed Vc11 , Ve1 1, Vf 11, Vg1 1 constant;

• MC12, ME12, MF12 or MG12 - this submode corresponds to the application to the thrust piston of the distribution device 100 connected to the connection end C, E, F or G of a high speed Vc12, Ve12, Vf12, Vg12 constant;

• MC13, ME13, MF13 or MG13 - this submode corresponds to the withdrawal of the thrust piston from the distribution device 100 at a constant speed Vr.

[0075] Note that the speeds Vc10, Ve10, Vf 10, Vg10 to Vc12, Ve12, Vf 12, Vg12 of each sub-mode are between 0.05 millimeters per second and 15 millimeters per second. The constant speed Vr is between 0.05 millimeters per second and 15 millimeters per second.

[0076] In Figure 9 the different operating modes of the distribution process are shown when the distribution device 100 is connected with a type D connection end. [0077] When the user II chooses a connection tip D and the latter is fixed inside the distribution device 100, the recognition means are automatically activated making it possible to initialize a control program corresponding to the chosen tip .

[0078] Thus the user II can, by means of the control button 400, select one of the following proposed modes in the control program:

• MD1

• MD2

[0079] In our example, namely the dental domain, the MD1 mode corresponds to a so-called “low viscosity liquid” mode. In this mode the user can choose one of the following sub-modes:

• MD10 - this submode corresponds to the approach of the thrust piston of the distribution device 100 connected to the connection end D at a constant speed Vd10;

• MD1 1 - this submode corresponds to the application to the thrust piston of the distribution device 100 connected to the connection end D of a constant low speed Vd1 1;

• MD12 - this submode corresponds to the application to the thrust piston of the distribution device 100 connected to the connection end D of a constant high speed Vd12;

• MD13 - this submode corresponds to the removal of the thrust piston from the distribution device 100 at constant speed Vr.

[0080] The MD2 mode corresponds in the dental field to a so-called “very viscous liquid” mode. In this mode, user U can choose one of the following sub-modes:

• MD20 - this submode corresponds to the approach of the thrust piston of the distribution device 100 connected to the connection end D at a constant speed Vd20;

• MD21 - this submode corresponds to the application to the thrust piston of the distribution device 100 connected to the connection end D of a constant low speed Vd21; • MD22 - this submode corresponds to the application to the thrust piston of the distribution device 100 connected to the connection end D of a constant high speed Vd22;

• MD23 - this submode corresponds to the removal of the thrust piston from the distribution device 100 at constant speed Vr.

[0081] Note that the speeds Vd10 to Vd12 and Vd20 to Vd22 of each sub-mode are between 0.05 millimeters per second and 15 millimeters per second. The constant speed Vr is between 0.05 millimeters per second and 15 millimeters per second.

[0082] Note that the tips A, B, D and F can be heated beforehand to increase the effectiveness of certain products contained in said tips.

[0083] In fact, heating dental composite resins improves their mechanical properties and thus increases their hardness, their adhesion and the quality of the degree of conversion. Heating and maintaining the tips at an ideal temperature reduces the sensation of injection, linked to a sudden temperature change, and thus improves patient comfort.

[0084] Also, heating solutions for endodontics potentiates their solvent power, thus increases the dissolution of organic and mineral materials by neutralizing microorganisms, and thus improves the irrigation treatment.

[0085] The tips can be heated by any known means arranged either in the charging support 600, or in the distribution device 100, or in the connection tip itself.

[0086] Note that the number of modes and sub-modes of the control program is not limited to those described previously, but that the number of the latter is adapted according to the field in which the distribution device 100 is used. .

[0087] We understand that the devices which have just been described and represented above have been done with a view to disclosure rather than limitation. Of course, various adjustments, modifications and improvements could be made to the examples above, without departing from the scope of the invention.
