Description

DEVICE FOR DELIVERING A DOSE OF A DISINFECTANT SOLUTION.

DOMAIN

The field of the invention relates to the field of health, public health and mass disinfection of hands. The field of the invention relates to the distribution of a disinfectant or any other solution conducive to eliminating a pathogenic agent from the hands of its wearer. In addition, the field of the invention relates to the field of interactive distributors with a user making it possible to optimize a service rendered.

STATE OF THE ART

Currently, in the field of disinfectant solution dispensers, the distribution is generally carried out by conventional methods. Traditional methods today have a drawback due to the slowness of the dose distribution, the contact with the machine (push button) or the narrowness of the access to the distribution point. These existing dispensers may be, for example, slow to detect the hand and/or slow to eject the dose, may require undesirable manual contact on a button, or may require the hand to be inserted into a hole or cramped place making risk from contact with the machine.

These drawbacks can deter pedestrians from using the machine and therefore from disinfecting themselves, because users often do not want to take the risk of contact with the machine, which will have been touched by another user, or do not want to wait line for a dose of gel. These state-of-the-art dispensers are not suitable for mass disinfection, due to their low amount of gel content.

The invention detailed below makes it possible to overcome the aforementioned drawbacks.

According to one aspect, the invention relates to a device for delivering a dose of a disinfectant solution comprising:

• a reception area designed to accommodate an individual's hand;
• a sensor arranged to detect the presence of a hand in said reception area, a hydraulic system comprising a storage tank for said disinfectant solution and configured to dispense a pressurized dose of said solution when the sensor detects the presence of a hand ;
• a head for dispensing said dose in the form of a flow dispersed in a predefined volume.

The invention can take the form of an automatic dispenser for a dose of disinfectant. One advantage is to allow an individual to wash their hands with a disinfectant solution without requiring contact with an element of the dispenser.

According to one embodiment, the dispensing head is arranged so as to deliver a dose of disinfectant solution into a projection cone, the projection axis of which is parallel to a vertical axis in a Cartesian coordinate system, said projection cone delivering a dose of disinfectant solution at an altitude lower than the altitude at which the dispensing head is positioned when the dispensing device is positioned in an operating position.

An advantage is to allow the solution to be projected downwards, or even towards the ground or even towards a part of the device arranged at a position lower than the position of the dispensing head. This arrangement makes it possible not to project a solution towards the head of an individual or even onto his clothing. The operating position is considered to be the position in which the device can be powered and in working order. An individual's hands are placed opposite the dispensing head in this operating position. The projection cone is directed along the Oz axis and downwards. According to one embodiment, the dispensing head can be oriented slightly with respect to the vertical axis Oz, by an angle of between 0° and 15° in order to offer better coverage of the hands of a individual by the projected solution.

According to one embodiment, the reception area comprises a first volume adapted to receive a hand and a second volume, called "release volume" defined around the first volume allowing a rectilinear longitudinal movement of the hand in the plane horizontal (x ₀ , y ₀ ), called "travel of passage", the volume of clearance allowing a stroke of passage of said hand over a distance of 40cm.

Clearance volume can be defined by free space around a target point. The target point may for example be a point in space located on a vertical axis equidistant from the dispensing head and from a proximal zone of a lower block forming a part intended to receive the volume of disinfectant solution not intercepted by an individual's hand. This part can be designed so as to convey a quantity of solution to a recovery tank. This part can be arranged and designed to facilitate the flow of the non-intercepted solution towards a collection zone. According to an alternative, the target point is located on the vertical axis passing through the outlet of the dispensing head at a distance of approximately 2/3 of the distance between the outlet of the dispensing head and the proximal part of the lower block .

The clearance volume can also be defined otherwise or in combination with the previous definition with the following definition: the clearance volume corresponds to a free volume allowing rectilinear movement in the horizontal plane of an individual's hand. This free volume can be designed to allow free movement of an individual's hand in the horizontal plane, said horizontal plane being located a few centimeters below the dispensing head over a distance of 40cm. According to one example, the free volume is not limited in distance, but it limits the orientation of the stroke of the hand. According to one example, an angle of 260° is left free to perform a rectilinear movement with one's hand in the horizontal plane under the dispensing head without touching the device of the invention.

According to one embodiment, the device comprises:

• a first upper block holding the dispensing head in such a way that it projects a dose of solution at an altitude lower than the altitude of the first upper block,
• a second lower block comprising a base making it possible to maintain said device on the ground and a surface for receiving the disinfectant solution distributed and not having intercepted the hand during its projection and;
• an intermediate block making it possible to join the first block F and the second block, said intermediate block comprising a proximal part facing the projection cone whose distance with the axis of projection is greater than 10 cm.

An advantage is to define a central zone of the device of the invention allowing maximum clearance to leave free the greatest number of strokes of a hand traversing a rectilinear movement in the horizontal plane. Another advantage is to make it possible to define a device of the invention having a structure defining a terminal such as a removable vending machine. One advantage is to allow the device to be placed at the entrance to public places, fairs, public transport or even shopping centers so that a greater number of people can clean their hands without stopping and therefore without interrupting a flow of people.

According to one embodiment, the intermediate block is laterally open. In this case, the intermediate block does not include a side part defining a reception area. In this case, the reception zone is defined by the proximal part of the lower block, the proximal part of the upper block and the proximal part of the intermediate zone. The so-called "proximal" part defines the part closest to the vertical axis passing through the dispersion point located at the end of the device's dispensing head.

An advantage is to provide a lower block in which a storage tank for disinfectant solution can be installed. According to one embodiment, a door or a hatch may be present in order to change the storage tank.

According to one embodiment, the lower block can also be designed to receive a possibly interchangeable power supply such as a battery. The lower part comprises a base or a base to hold the structure (or the frame) of the device of the invention upright , for example, on the road. According to one example, the lower block comprises a counterweight to form a stable and not easily transportable terminal.

According to one example, the upper block comprises a visible display space. In the frame of the upper block, a solenoid valve can be arranged so as to deliver a dose of disinfectant solution to the dispensing head.

According to one example, the size of the intermediate block is reduced to a minimum in order to define numerous possibilities of hand trajectories coming from the front, from the side or even from behind the device.

According to one embodiment, the proximal part of the intermediate block forms an edge of a geometric shape having two intersecting planes, the two intersecting planes making it possible to release a lateral volume of the device on either side of the edge. One advantage is to define corridors defining trajectories relating to the movements of individuals likely to come from several places. This arrangement allows an optimal configuration to ensure the rapid delivery of a plurality of doses to a plurality of individuals presenting themselves according to a flow of people arriving from different directions.

According to another variant, the device of the invention does not comprise a lower block. According to this mode, the device is fixed, for example, to a facade, to a wall or any vertical structure or even to a ceiling or a ceiling light. In this last embodiment, the dispensing head is arranged on the lower part of the device, the individuals presenting their hands under the dispensing head. According to the variants, the invention is therefore presented either as a removable bollard that can be deployed in different places, or as a device to be fixed to an already existing structure.

[ -90°; +90°], the angle being measured with respect to the normal to the mean plane coinciding with the front face of the dispensing device. In this case, the clearance opens up the possible trajectories of the hands of individuals over 180°.

According to another embodiment, the reception area is designed to allow orientation of the passage of the hand at an angle included in the range [−115°; +115°], the angle being measured with respect to the normal to the mean plane coinciding with the front face of the dispensing device. This opening makes it possible to accommodate hand trajectories defining straight longitudinal strokes coming from an area located behind the device. The zone behind the device corresponds to the region facing the region located in front of the front face 410 of the device.

According to another example, the intermediate zone is a rod, a tube or a beam of smaller section. According to one example, the profile of the intermediate zone allows an orientation of the stroke of passage of the hand according to an angle comprised in the range [-130°; +130°] or even [-145°; +145°]

According to one embodiment, the sensor is a beam interruption sensor comprising an emitter of an optical beam and a reflecting device, the emitter and the reflecting device being arranged on either side of the reception area of so that the presence of a hand intercepts the beam emitted by the transmitter. According to one example, the transmitter emits an infrared beam. According to another example, the beam is in the visible range.

According to one example, the reflective device is a mirror or a reflector.

According to other examples, the sensor is a shape recognition optical sensor or a sensor comprising an emitter and measuring an amount of reflected light energy.

The sensor can for example be located on the upper edge of the lower block of the device. In this case the transmitter can be arranged to direct a beam towards the upper part inclined upwards of the intermediate block. In this case the reflective part can be arranged at the top of the intermediate block or on the lower part of the upper block. Many layout configurations make it possible to position the reflecting part opposite the emitting part so that the beam crosses the reception area.

According to one embodiment, the hydraulic system comprises a pressurized reservoir of the disinfectant solution maintained under pressure by means of a pump. According to this example, the pressure tank comprises a volume of a gas such as air compressing a volume of disinfectant solution. The gas volume can be integrated into a rubber bladder. A pneumatic damper can be used within the pressure tank. A pressure of the disinfectant volume is for example maintained above a predefined threshold. According to one example, a pump is automatically controlled to take a volume of disinfectant solution from the storage tank to inject it into the pressure tank so as to maintain a sufficient level of pressure. According to one example, a pressure of between 1 bar and 6 bars is maintained in the pressure tank. According to a preferred mode, a pressure of between 2 and 4 bars is maintained in the pressure tank.

According to one embodiment, the hydraulic system comprises a solenoid valve controlled by a first computer, said first computer being configured to receive first instructions from said sensor and to deliver commands for actuating said solenoid valve according to the values of the first instructions. The solenoid valve can be configured to open automatically for a preset time. The solenoid valve advantageously comprises an interface allowing it to be controlled electrically. According to one example, a computer generates electrical instructions to the solenoid valve for a predefined period. According to an example, the opening time of the solenoid valve is between 1 ms and 250 ms. According to another example, the opening time of the solenoid valve is between 1 ms and 50 ms. According to another example, the opening time of the solenoid valve is between 1 ms and 10 ms.

According to one embodiment, the first computer is configured to receive pressure data from said disinfectant solution within the hydraulic system, and to issue commands for withdrawing a volume of said disinfectant solution from the storage tank. To this end, according to one example, a probe is positioned in the pressure tank, when the pressure level is below a threshold, the computer generates a command to open a pump making it possible to automatically draw off a volume of disinfectant solution of the storage tank.

According to one embodiment, a first valve is arranged upstream of the solenoid valve to regulate the pressure upstream of the solenoid valve. This first valve can also be a solenoid valve. According to one example, the first valve is positioned between the pressure tank and the solenoid valve. According to one example, the first valve is sized to ensure a predefined pressure at the inlet of the solenoid valve. According to another example, the first valve is adjustable in flow.

According to one embodiment, the dispensing head comprises a means for dispersing the microdroplets in a predefined spatial volume, the dispersion being carried out by aerosolization, nebulization or spraying.

According to one embodiment, the distribution head is a head comprising a plurality of distribution channels of smaller diameters than the upstream diameter conveying the dose under pressure of disinfectant solution so as to distribute the dose in the form of microdroplets in a volume predefined space.

According to one embodiment, the dispensing head is a nozzle so as to ensure the dispersion of the dose in the form of microdroplets in a predefined spatial volume.

According to one embodiment, the disinfectant solution is a hydroalcoholic gel, a hydroalcoholic solution, an antiseptic solution, or a disinfectant solution for eliminating a pathogenic agent on the surface of the skin.

According to one embodiment, a sensor is placed inside the storage tank to measure the remaining volume of disinfectant solution. When a threshold level is reached, an electrical signal is transmitted to the computer so that the latter can automatically configure the transmission of a data frame according to a communication protocol to deliver information to a remote server. Thus, a replenishment of disinfectant solution can be programmed. In the event that a large fleet of devices is deployed, this information can be gathered in a database to automatically organize a replenishment circuit for said fleet.

Figure 1 shows an example of a device 1 of the invention in perspective. This device 1 comprises an upper block 41 comprising a dispensing head delivering a dose of disinfectant solution downwards, a lower block 42 making it possible to define a removable dispensing terminal that can be arranged on any surface. The device 1 of the invention comprises an intermediate block 43 forming a connection between the upper block and the lower block. The intermediate block 43 is designed to release a maximum free volume in the projection zone V₂the dose of disinfectant solution. The disinfectant solution is diffused according to a cone of projection 100 preferentially downwards, that is to say according to a vertical axis (O,z₀)_. According to one example, this diffusion axis Ap can be slightly inclined according to the design variants.

The device 1 of the invention has a front face 410, 420 defining a front zone of the device and a rear zone located on the other side opposite the rear face of the device 1 of the invention.

Figure 2 details the main elements of the device of the invention. The device of the invention is a device for dispensing a volume of disinfectant solution. The device makes it possible to deliver a predefined dose or a predefined volume or more generally a predefined quantity of a pressurized disinfectant solution. The device delivers a dose quickly, i.e. in less than a second, 1s. The delivery can be carried out at high speed, that is to say possibly according to a delivery of disinfectant solution at least every second. The disinfectant solution may for example be of a hydroalcoholic nature.

According to one embodiment, a pump 12 makes it possible to pump a volume of disinfectant solution from a storage tank to a pressurized tank. The storage tank 11 is, for example, a large capacity and interchangeable container 11 which can be a standard container with a capacity greater than 5L, according to one example, 5, 10 or 20 liters or even more.

The pumping makes it possible to send a quantity of liquid, corresponding to the disinfectant solution, into a container 13. The container 13 is a pressurized tank. This can be, for example, a pneumatic shock absorber or a pressure accumulator. According to one embodiment, the arrival of the liquid 14 in the container 13 causes the compression of a gaseous volume 15 making it possible to accumulate pressure. The pressure of assembly 13, 14 and 15 is detected by means of a device 35 which may be a pressure probe. According to a first variant, the desired pressure is advantageously less than 10 bars. An interesting range is the pressure range of 2 to 6 bar. In this range, this solution has an advantage in terms of the efficiency of the mechanical construction and in terms of the dispensing service pressure allowing a sufficient speed of delivery of the product. The latter, which may initially be in the form of a gel, can be dispersed by pressurizing the use of a suitable dispensing head. A dispensing head is advantageously chosen so as to favor the division of the flow of fluid into several jets or nebulization, that is to say a dispersion into droplets or microdroplets. According to one embodiment, a pressure and flow control device 16 is usefully located between the reservoir 13 of pressurized liquid and the controlled delivery device 17 which can advantageously be a solenoid valve in one embodiment.

According to another variant, the pressure can be less than 2 bars and greater than 0 allowing the dispersion of a fluid whose viscosity is low.

According to one embodiment, a dispensing head 18 allows the controlled delivery of a dose of disinfectant solution 22. It comprises the electromechanical activation of a controlled delivery device 17. This activation can be generated automatically by an electrical command delivered by an electronic control device 32 or more generally using a computer. The electronic device can take, for example, the form of an electronic card. The opening of this controlled delivery device 17 causes the circulation of the fluid, that is to say the disinfectant solution, towards the dispensing head 18.

According to a first variant, the dispensing head 18 is a spray-type nozzle, which disperses the liquid into several jets of liquid and advantageously of droplets or microdroplets. Depending on the case where the nozzle requires another fluid such as a gas to nebulize the sprayed volume, a circuit for conveying a volume of pressurized air can be arranged within the device 1 of the invention.

The nebulization or the dispersion of the jet allows a wide coverage of the hand, as well as a reduced contact speed with the hand having the advantageous effect of reducing the undesirable projections of the solution outside the reception area.

The pressure supplied by the system 10 allows rapid ejection in a short period of time, for example a period of less than 0.4 seconds.

According to one embodiment, the control of the device is operated by an electronic circuit 32 which is, in its most elementary form, a computer associated with a memory. According to a first variant, the electronic circuit 32 contains a microcontroller which has a wireless communication function 33, having the advantageous effect of telemetric reporting and remote control. According to one example, this system 32 and 33 makes it possible to warn a third party remotely that the storage tank 11 of the device 1 is almost empty in order to program its filling.

According to one embodiment, the control 30 of the machine has an electrical power supply 31 which can advantageously be the electrical mains, a battery, a battery and its charging system, the three sets.

According to one embodiment, the electronic circuit 32 receives information from a probe 35 or from any other signal input, for example a signal coming from a presence sensor of an individual's hand.

An optical detector 34 and its reflector Re make it possible to detect the hand of the user in a predefined volume. In a first variant, the detector 34 and its reflector Re advantageously operate on the principle of interrupting a light beam, such as an infrared beam. In a second variant, the detector 34 operates by radio wave, or else by microwave.

According to one mode of operation, the electronic circuit 32 receives information from the hand presence sensor or from the pressure probe to automatically generate power supply instructions for the various elements of the device of the invention 1, for example the power supply pump 12 and solenoid valve 17.

FIG. 2 represents the hydraulic circuits between the various hydraulic elements by LH junctions and represents the electrical circuits between the various elements comprising electrical interfaces by LE junctions.

According to one embodiment, all the elements of the device 1 can be arranged and configured to result in the release of a dose of disinfectant solution in a period of time of less than 0.3 seconds.

Figure 3 shows a top view in section of an embodiment of a device of the invention 1. The section plane corresponding to the top view of Figure 3 is shown in side view in Figure 6 and in front view in Figure 7.

The dispensing head 18 delivers to point A, called the “dispersion point”, a dose of disinfectant solution after detecting the presence of an individual's hand in the reception area. In this example, the dispensing head 18 expels into a spray cone located below the dispersion point Pt A along the vertical axis (O, z ₀ ) a dose of solution. The hand is positioned under the dispersion point A, in this configuration, the solution is almost completely delivered to the individual's hand.

The hand is positioned so that it intercepts the throwing cone. The device 1 comprises a reception area making it possible to define a projection cone comprising a volume of an individual's hand.

In FIG. 3, a first zone is represented by a circle 41 centered on a point located on the vertical axis (O, z) such as point A. the diameter of the circle 41 is substantially larger than the wheelbase of a open hand of an adult type individual. Circle 41 has a diameter of approximately 30cm more generally within a range [20cm, 40cm].

A second circle 42 is defined concentric to the circle 41. The diameter of the circle 42 has a diameter between 30 cm and 60 cm. The end of the proximal part of the intermediate block 43 or of the section 45, which can form a line, a point or a plane, is located between the diameter of the first circle 41 and the diameter of the second circle 42.

FIG. 5 represents in more detail a sectional view of a reception zone Zc intercepting a projection cone, for example delimited by the circle 41. According to a mode of manufacture of the device of the invention, the reception zone Zc comprises a region delimited by a circle 41, called the exclusion zone, of diameter Φ 41 and substantially defining a zone of position of the hand of a user according to all its orientations. A region delimited by a circle 42 of diameter Φ 42 represents the minimum inclusion zone of the end of the proximal point of the intermediate block 43. The exclusion zone defined by the circle 41 is centered on a point on the vertical (O , z) passing through point A, denoted Pt A. It represents the zone in which a solid part of the device 1, such as an upright 45 must be excluded, because it could obstruct the passage of a hand. The shape 45 represents a section in section of the intermediate block of FIG. 1. The point B materializes the edge B of the intermediate block 43 of the device 1 or of any other physical object integral with the device defined closest to the point A in the plane section of figure 3.

According to one embodiment, the point B makes it possible to delimit the reception zone Zc. Its pointed or ridged design opens up the clearance zone while defining a natural indication for positioning the hand.

The invention takes advantage of a reception area defined by at least three edges of the device of the invention comprising a broken line or a point or an edge which allows an individual to position his hand naturally. Line breaks or breaks such as points or edges define a guide or a natural indication to come and position your hand in the right place.

According to one embodiment, the entire surface covered without material obstruction 45 allows movement of a hand in the circle 41 in directions around point A in an open angle of more than 250°, or even 270°

The angle theta of the space bounded by straight lines 47 and 48 in Figures 3 and 4 makes it possible to define corridors of passage for individuals extending their hand without stopping. This angle theta is measured relative to the normal Np to the mean plane parallel to the front face of the device 1 of the invention. The normal is defined by the Np axis in Figure 3. In this example Np is collinear with the axis of the individual's arm, but this is a special case. The arm could be inclined with respect to this axis. The axis Np defines with the vertical axis a plane of symmetry of the device 1.

The angle theta is advantageously comprised in the range [-90°, 90°], offering an amplitude of movement of the arm over at least 180° to allow unhindered circulation of the hand 44 of the user. This provision provides for a lateral clearance of 180° around point A to allow multidirectional pedestrian use.

This angle theta is advantageously included in the range of angles [−120°, +120°], see [−140°, +140°], to allow the user's hand 44 to move freely.

Figure 4 shows the passage of 3 individuals in corridor 49 who hold out their hand and of an individual in corridor 46 who also holds out his hand. The corridor 49 is delimited by the border of the intermediate block 432 extended by a line 47 and the corridor 46 is delimited by the border of the intermediate block 431 extended by a line 48. In this configuration, it is understood that individuals can come from different directions .

Figure 6 shows a side elevational view of one embodiment of a device of the invention. According to one embodiment, the point A of dispersion of the solution is advantageously located at the lowest point of a frame 54 of the upper block 41. The dispensing head 18 is therefore arranged in this arrangement to form the lowest part of the upper block 41. The section shows a pointed shape or triangular silhouette so as to indicate to a user where to position his hand. This arrangement has the advantage of being intuitive and of guiding the position of the hand at the intersection of the tips and edges of the reception area.

The proximal face of the lower block is represented here by a ridge 53. Depending on the geometric configurations, the highest part of the lower block 42 can form a ridge or a point or any other regular or irregular geometric shape having a culminating point. It is understood that the highest point is referenced with respect to a vertical axis. This is the highest point of the lower block delimiting the reception area.

The distance d52 between the proximal part 53 of the lower block 42 and the proximal part Pt A of the upper block 41 is between 10cm and 50cm.

In the configuration of FIG. 6, the hand of a user is represented at a distance d51 from the proximal part pt A of the upper block 41.

Figure 7 shows a front view of an embodiment of a device 1 of the invention. This front view represents the hand of a user located substantially in the middle of the reception zone delimited by the proximal part 61 of the lower block 42, the proximal part 62 of the upper block 41, the proximal part B of the intermediate block 43. Naturally, these three edges define a positioning indication for placing one's hand under the dispensing head.
