Description

Device for receiving and connecting an electronic device. The present invention relates to a device for receiving and connecting an electronic device, in particular for hospital applications, and more particularly to a device for waterproof and antibacterial supply for a mobile electronic device. Conventionally, the electronic devices operate according to a power supply that can be provided either by a charger (including for example a power converter), or by a battery of the device, itself can be recharged sporadically by such charger. The charger usually powers the electronic device via a power outlet of the device. When the electronic device is installed in a protective shell, it is usually provided at least one opening to access the power socket of the device to connect the charger.

However, when it is desired to obtain a waterproof protective shell, it will be understood that such opening of the shell for accessing the charger to the power socket of the device is not desirable. Moreover, in the collective health institutions (hospitals, clinics, or other), the use of electronic devices is developing widely, in particular to offer new services to patients, improve comfort and access to health care. information, but also to allow medical staff to better follow patients. For example, medical staff may have a digital tablet with which it is possible to enter data relating to the medical follow-up of each of the patients examined.

However, electronic devices for hospital applications can be accessed and manipulated by visitors, patients and staff members. They therefore present a source and a potential carrier not insignificant for nosocomial diseases and infections. In fact, to improve the health of the establishment and limit the risk of nosocomial infections, a careful and regular cleaning of these devices is strongly recommended. It will be understood that these cleanings are nevertheless likely to generate electrical and electronic failures of the apparatus, inherent to an excess of moisture, splashing water or a disinfectant product for example. In particular, these failures can occur following a liquid infiltration via the aforementioned opening of the shell for the charger of the device. Also, it will be understood that there is a need to improve the safety of electronic devices used in the health sector, as well as their sealing for resistance to regular cleaning.

The present invention improves the situation. In this case, the invention provides a device for receiving and connecting an electronic device, particularly for hospital applications, which is waterproof and antibacterial.

For this purpose, the invention aims a reception device comprising at least: a protective shell, waterproof and antibacterial, intended to accommodate the electronic device, the protective shell having at least two electrical connections on an outer surface of the protective shell, the electrical connections being further connected to a charging socket for electrically powering the apparatus; and a charge, waterproof and antibacterial carrier, comprising at least two first electrodes on an outer surface of the charge carrier and adapted to come into mechanical contact with said electrical connections when said first electrodes are facing electrical connections of the shell. Advantageously, the protective shell and the load support: - are adapted to be secured by magnetic attraction respectively of said electrical connections and said first electrodes; and form a sealed and antibacterial assembly upon contact of said electrical connections and said first electrodes. Also, the sealed and antibacterial assembly formed by the shell and the support, on the one hand avoids the presence and proliferation of bacteria and, on the other hand, resists splashing water inherent in a cleaning for example. Thus, the device for receiving and connecting an electronic device is particularly suitable for use in a hospital environment where sanitary measures are strict and frequent cleanings, effectively limiting nosocomial diseases and infections. The device can then be vigorously cleaned with water and / or disinfectants, without the risk of damaging the on-board electronics of the device, in this case the electronic device. As such, the device can be cleaned more effectively without risk of damage, which further improves the health conditions of a patient's environment and further limits the risk of nosocomial infections.

The device also allows: an automatic supply of the device when the protective shell is secured to the load support via the mechanical contacts between the electrical connections and the first electrodes (no longer requiring the opening of the shell for the passage of the charger); - a simple attachment, removable and protected from the electronic device on the load support. According to a particularly advantageous embodiment, the device is such that: said protective shell further comprises at least two communication connections on an outer surface of the protective shell, the communication connections being further connected to a communication interface for communicating data with the apparatus; said load carrier further comprises at least two second electrodes on an outer surface of the load carrier and adapted to mechanically contact the communication connections when said electrodes are facing communication connections of the shell. Advantageously, the protective shell and the load support are in communication during a contact of said communication connections and said second electrodes. Thus, the device also allows to automatically establish a communication link between the device and the support when the protective shell is secured to the load carrier via the mechanical contacts between the communication connections and the second electrodes.

According to an advantageous embodiment, the electrical and communication connections on the shell, as well as the corresponding electrodes on the support, are arranged in an asymmetrical arrangement. Thus, the mechanical contacts can only be made in a given position of the shell relative to the support. It will be understood that this embodiment makes it possible to prevent the connections from being facing each other and in contact with incompatible electrodes, which could lead to short circuits. It should be noted that additional pairs of electrical and / or communication connections, and corresponding first and second electrodes, may furthermore be arranged respectively on the shell and the support.

Typically these additional pairs allow for example to adapt the contacts between the shell and the support according to USB technologies ("Universal Serial Bus" for Universal Serial Bus), Ethernet or other. In this sense, a connection of the shell and an electrode of the support may for example be provided by pin of a USB or Ethernet cable.

In addition, according to a possible embodiment, the protective shell and the load support are further adapted to be secured by magnetic attraction respectively of said communication connections and said second electrodes; and - form a sealed and antibacterial assembly during a contact of said communication connections and said second electrodes. The additional magnetic attraction provided by the communication connections and the second electrodes reinforces the securing of the protective shell and the load support, while also providing a communication channel allowing the electronic device to communicate data in wireframe, via the mechanical contacts between the communication connections and the second electrodes. In an advantageous embodiment, said charging support further comprises a control accessory, waterproof and antibacterial, whose control instructions are sent to the electronic device via said contact of said communication connections and said second electrodes. This accessory makes it possible to offer on the device additional control functions making it possible, for example, to improve the comfort of use of the electronic device accommodated in the shell. According to another advantageous embodiment, said load support further comprises a communication module connected to: said second electrodes; and at least one communication link with a wide area network.

Advantageously, the communication module interprets data exchanged between said second electrodes and said wide area network. Therefore, the communication module makes it possible to establish communications with various computer entities (as mentioned below) and interprets the data relating to these communications so that they can be sent and processed by the electronic device housed in the shell. According to one possible alternative, said communication link is established according to a line carrier communication protocol - CPL, via at least one power supply received by the load carrier.

According to another possible alternative, said communication link is an Ethernet cable that provides a power supply to the load support according to the IEEE 802.3af standard. The IEEE 802.3af standard, also called POE for "Power Over Ethernet" (thus referred to in the following description), aims to pass a supply voltage in addition to the data transmitted via an Ethernet link. Alternatively, the load support further comprises a communication interface module connected to said communication module, the communication interface module being adapted to establish said communication link, wired or wireless. Thus, the data received by the communication module may come from different communication links (Wi-Fi, Bluetooth, or other), and interpreted so as to be communicated to the electronic device via the mechanical contacts between the communication connections. and the second electrodes.

Advantageously, said load support receives at least a first power supply and further comprises an electrical transformation module capable of transforming the first power supply received into a second power supply adapted to the device, the second power supply electrically supplying at least said power supplies. first electrodes.

In this way, the power supply provided by the load carrier can be adapted to a power supply required for the proper operation of the apparatus housed in the hull. The load of the latter is improved while limiting the risk of damage to the device. On the other hand, the load support can receive any type of power supply (power supplies, CPL, POE, or other) which multiplies the potential sources of electrical energy to power the connections of the shell via the electrodes of the support. According to one possible embodiment, the protective shell is composed of an antibacterial material based on silicone mixed with silver and / or copper particles.

According to one possible embodiment, the protective shell is closed with: on at least one face of the shell, a transparent zone corresponding to the electronic device; and on at least one face of the shell, respective reception areas of said electrical connections and said communication connections.

In this way, the closed shell effectively isolates the apparatus from any splashing of liquid such as water or disinfectants. The electrical and communication connections also allow the device to be powered and communicate without requiring an opening of the shell for the passage of a charger or a communication link.

As a variant, the protective shell comprises at least: on at least one face of the shell, an opening, on at least one face of the shell, respective reception zones of said electrical connections and said communication connections; an O-ring seal placed inside the shell, between the shell and the apparatus, at the periphery of the opening, on a zone of cooperation of the shell and the apparatus, - a transparent protective film antibacterial covering the device at least on a surface in correspondence with the opening. In fact, the device is directly accessible by the user, which allows to maintain good detection sensitivity when the device has a touch screen. In addition, the opening is closed by the device, and sealed by the O-ring. This opening is also a disinfected area thanks to the transparent film, so that the shell is effectively waterproof and antibacterial. According to an advantageous embodiment, the load support further comprises an autonomous power source. The autonomous electrical power source makes it possible, in particular: to temporarily supply the electronic device, for example during a power failure at the power supply received by the support, or even to continue to supply the electronic modules of the support so as to continue communication and data interpretation with the communication module. In a particular embodiment, at least one first O-ring seal is arranged at the periphery of: - said electrical connections; and / or - said first electrodes. In addition or alternatively, at least one second O-ring seal is arranged at the periphery of: - said communication connections; and / or - said second electrodes. According to a possible embodiment, said protective shell comprises at least: a front part comprising at least a first mechanical connection on at least one periphery portion of the front portion; a rear part comprising at least one second mechanical connection on at least one periphery portion of the rear part, the periphery portion of the rear part being opposite said peripheral portion of the front part, and the second mechanical connection being adapted to mechanically cooperate with said first mechanical connection; an o-ring seal installed peripherally of said front portion or said rear portion so as to be in contact with said front and rear portions when said first and second mechanical connections cooperate.

Thus, when said first and second connections cooperate, the front portion and the rear portion are secured mechanically and sealingly with the O-ring.

This embodiment of the shell is simple to implement and allows a good seal of the hull. Other advantages and characteristics of the invention will appear on reading the following detailed description of exemplary embodiments presented for illustrative purposes, in no way limiting, and with reference to the appended drawings in which: FIG. 1 illustrates an example embodiment of the reception and connection device of an electronic device according to the invention; - Figure 2 shows an illustration of the protective shell of the device in a rear view; - Figure 3 illustrates another rear view of the protective shell and in which there is shown a possible electrical arrangement of the shell; FIG. 4 illustrates an exemplary embodiment possible for the protective shell; FIG. 5 illustrates an embodiment of the device according to which o-ring seals are placed at the connections of the shell and / or at the electrodes of the support; FIG. 6 illustrates an example in which the shell of the device is secured by magnetic attraction to the support; - Figure 7 shows schematically the load carrier with electrical elements and electronic modules that compose it; FIG. 8 illustrates an exemplary embodiment for the waterproof and antibacterial protective shell; - Figures 9a and 9b show an embodiment to secure a front portion and a rear portion of the shell to make it waterproof and install an electronic device.

For the sake of clarity, the dimensions of the various elements shown in these figures are not necessarily in proportion to their actual dimensions. In the figures, identical references correspond to identical elements.

Referring to Figure 1 on which there is illustrated an embodiment of the docking device and connection of an electronic device according to the invention. In this embodiment shown in FIG. 1, the device 1 comprises in particular: a protective shell 2, comprising electrical connections and communication connections (not visible in this view orientation); a load support 3 comprising a support plate 5 and a housing 6; first electrodes Ela, Elb, El c, El d; second electrodes E2a, E2b; - A CLA control accessory such as a keyboard, a mouse or a touch screen for example. The protective shell 2 accommodates an APP electronic device. The device APP may in particular be a mobile electronic equipment such as: - a smartphone, - a digital tablet, - a touch screen, - or other. The protective shell 2 has at least two electrical connections on at least one of its outer surfaces, and more particularly in this figure, on the rear surface (not visible) of the shell. In FIG. this rear surface letting appear the CEa, CEb, CEc, CEd electrical connections of the hull. At least two of these electrical connections are for directly powering the device or a battery system of the device. For example, the power supplied via the first pair of electrical connections CEa, CEb is 9 volts, and the power supplied via the second pair of electrical connections CEc, CEd is 3 volts ( eg issue of a USB cable supply). Thus, APP device housed in the shell can be powered by different power supplies adapted to its operation. It will be understood that these different possible power supplies make it possible to make the device 1 compatible with different electronic devices requiring various supply voltages. The load support 3 comprises at least the first two electrodes Ela, Elb on at least one of its outer surfaces, such as the plate 5 of the support 3 for example. The first two electrodes Ela, Elb are intended to be brought into contact with the pair of connections CEa, CEb to provide a power supply to the device in the shell. In addition, the load support 3 may comprise at least two other first electrodes Elc, Eld intended to be brought into contact with the pair of CEc connections, CEd to provide another power supply to the device.

The electrical connections CEa, CEb, CEc, CEd and the first electrodes Ela, Elb, Elc, Eld can be made in ferromagnetic materials, one being a magnetized material, and the other being a material based on iron or aluminum. steel typically. Thus, when the first electrodes Ela, Elb are, for example, facing electrical connections CEa, CEb, a magnetic attraction is generated between the electrical connections and the electrodes. By way of purely illustrative example, it is the first electrodes which are in magnetic material, and they magnetically attract the electrical connections which are made of iron. The magnetic attraction generated makes it possible to bring into contact the electrical connections of the shell and the first electrodes of the support when they are opposite, and respectively close to (typically at a distance of less than 5 centimeters). It will be understood that such a magnetic attraction makes it possible, during the aforementioned contact, to join the protective shell 2 to the support 3.

The first electrodes Ela, Elb, Elc, Eld may be a pair of electrodes comprising an anode and a cathode. The first electrodes Ela, Elb can electrically power the electrical connections CEa, CEb when they are respectively in contacts. Furthermore, the first electrodes Elc, Eld can also electrically power the electrical connections CEc, CEd to their contact. The power supply received by the electrical connections from the first electrodes Ela, Elb, Elc, Eld is electrically driven until the load of the APP device. This power supply allows the device to operate, or if necessary, to recharge a battery of the device.

Thus, it will be understood that the contacts formed between the electrical connections CEa, CEb, CEc, CEd and the first electrodes Ela, Elb, Elc, Eld are conductive, so that the APP device can receive a load power supply provided by the support. Moreover, the protective shell 2 may comprise at least two communication connections CCa, CCb on at least one of the outer surfaces. In the example illustrated in FIG. 2, the communication connections CCa, CCb are placed on the same face of the shell (in this case the rear face), close to the electrical connections CEa, CEb, CEc, CEd. Advantageously, the pairs of electrical and communication connections are arranged in an asymmetrical arrangement to prevent the connections of the shell being able to come into contact with incompatible electrodes of the support. The two communication connections CCa, CCb are connected to a communication interface of the electronic device. This interface can be provided to communicate data with the device. The communication interface may be the aforementioned charging socket when the device can receive data via this socket, or a separate interface (not shown in the figures), such as a USB socket, an RJ45 socket, or other. Referring again to FIG. 1, the load support 3 may further comprise at least two second electrodes E2a, E2b on at least one of its outer surfaces. The second electrodes E2a, E2b may be a pair of electrodes comprising an anode and a cathode so as to communicate, according to electrical pulses for example, data to the communication connections CCa, CCb when the connections and the electrodes are respectively in contact. . The communication connections CCa, CCb and the second electrodes Ela, Elb are for this purpose in a conductive material. Thus, when the connections and the electrodes are respectively opposite and in contact, the formed contact is conductive. The communication interface of the apparatus is then able to receive, via the connections CCa, CCb, data transmitted by the second electrodes E2a, E2b. According to a possible embodiment, the communication connections CCa, CCb and the second electrodes E2a, E2b can also be made according to ferromagnetic materials, one being a magnetized material, and the other being a material based on iron or aluminum. steel for example. In the same way as the electrical connections CEa, CEb and the first electrodes Ela, E2b, a magnetic attraction can then be generated between the communication connections and the second electrodes. This additional magnetic attraction makes it possible to further strengthen the fastening of the protective shell 2 with the support 3.

However, when the shell and the apparatus which it receives are light, or that a weak resistance of joining is desired (for example to be able to easily separate the shell and the support), only the electrical connections CEa, CEb and / or CEc, CEd and the corresponding electrodes are in ferromagnetic materials to generate a lower magnetic attraction between the support and the shell. In another possible embodiment, only the communication connections CCa, CCb and the second electrodes E2a, E2b are in ferromagnetic materials to generate a lower magnetic attraction between the support and the shell.

In addition, it will be understood that the contacts formed between the communication connections CCa, CCb and the second electrodes E2a, E2b make it possible to place the support 3 and the shell 2 in communication, and more particularly the APP device that the shell accommodates. The electrical connections CEa, CEb, CEc, CEd and the communication connections CCa, CCb are disposed on an outer surface of the shell 2.

In fact, the power supply and / or the data communicated are fed into the shell, up to the charging socket and / or the communication interface of the APP device, without an outer surface opening of the hull is necessary for the passage of a charger of the device or a communication link.

The electrical and communication connections are arranged on the surface of the shell in a sealed arrangement. Embodiments of this arrangement are detailed below. In one possible embodiment, the electrical and communication connections on the one hand, and the first and second electrodes on the other, are made of ferromagnetic materials. In this case, the magnetic attraction of the electrical connections CEa, CEb, CEc, CEd with the first electrodes Ela, Elb, Elc, Eld can be provided to be opposed to the magnetic attraction of the communication connections CCa, CCb with the second electrodes. electrodes E2a, E2b (for example having inverted magnetic polarities). Thus, when the connections are opposite the bad electrodes, the connections are magnetically repulsed. Thus, the user must correctly position the shell and its connections vis-à-vis the support electrodes for there to be an effective connection. In the illustrated embodiment, the support and the shell comprise four electrical connections CEa, CEb, CEc, CEd. However, this is an example of non-limiting embodiment In fact, it will be understood that the device may comprise only a single pair of electrical connections (eg CEa, CEb connections) which is sufficient to provide a power supply to the device housed in the shell via at least a pair of first support electrodes (Ela, Elb typically).

In an embodiment with only a pair of electrical connections and communication connections, it is advantageous to arrange the pairs of connections of the shell 2 and the corresponding electrodes of the support 3 in an asymmetrical arrangement on their outer surface. In this way, the electrical connections CEa, CEb can not be compared with the second electrodes E2a, E2b, and the communication connections CCa, CCb can not be compared with the first electrodes Ela, Elb. In this case, it will be understood that the shell 2 can be secured to the support 3 in only one mounting direction. Such an embodiment makes it possible to ensure that the connections of the shell can only be compared with the corresponding electrodes of the support. Thus, short circuits inherent in improper handling of connections with incompatible electrodes are avoided. As a purely illustrative example, to obtain an asymmetrical arrangement, it is possible to provide different spacing distances between the electrical connections CEa, CEb (and respectively the first electrodes Ela, Elb) and between the communication connections CCa, CCb (and respectively the second electrodes E2a, E2b corresponding). For purely illustrative purposes, the distance between the centers of the electrical connections CEa, CEb is 4 cm and 3 cm respectively between the centers of the communication connections CCa, CCb. Thus, for connections 1 cm in diameter, there can not be simultaneous contact between the pair of first electrodes Ela, Elb and the pair of communication connections CCa, CCb, or between the pair of second electrodes E2a, E2b and the second electrode. pair of electrical connections CEa, CEb. Referring now to Figure 3 which shows a rear view of the hull, with an example of electrical arrangement of the hull relative to the embodiment of Figure 1, comprising four electrical connections. In this rear view, the hull elements visible directly from the outside of the hull are shown in full lines, and in discontinuous lines the elements inside the hull (not visible from the outside of the hull). .

The electrical connections CEa, CEb, CEc, CEd and communication CCa, CCb are installed on the surface of the rear face of the shell 2, and are electrically connected to the charge socket P of the APP device. In this example, it is considered that the load taking P is also a communication interface of the APP device. The connections can respectively be connected to the socket P via the electrical connections LEa, LEb, LEc, LEd on the one hand, and the communication links LCa, LCb on the other hand. Electrical junctions JE and JC communication can be installed respectively between the electrical connections CEa, CEb, CEc, CEd and communication CCa, CCb, and electrical connections LEa, LEb, LEc, LEd and communication links LCa, LCb. Each junction may include in particular an electrical link between the connections and the links. The electrical link is arranged to cross the shell at one of the connections and electrically connects them to the corresponding links. The electrical and communication connections may be molded, or bonded, to the outer surface of the shell so that the outer surface and the connections form a sealed wall. It should be noted that the connections are thus arranged to obstruct the reception area of the connections on the outer surface of the shell, blocking passage of solid or liquid particles. This electrical arrangement of the shell is waterproof, avoiding the intrusion of particles in the protective shell.

In additional security, the electric junctions JE and JC junctions may further comprise an O-ring seal, surrounding for example the electrical connection of the junction. These seals (not shown in the figures) are arranged to be compressed between the connections of the shell and the outer surface of the shell, and that since the connections are assembled to the shell. Thus, it will be understood that the electrical arrangement of the shell is sealed, limiting the risk of electrical and electronic failures of the APP device. The protective shell can be made according to: - a closed structure, or - an open structure with an arrangement of the apparatus for closing the opening of the structure.

"Closed structure" means a shell which, once assembled, does not have an apparent opening on its outer surface, thereby preventing the introduction of particles, solid or liquid, inside the shell.

In an embodiment with a closed structure, the shell 2 may comprise: a transparent zone in correspondence of the electronic apparatus APP on at least one front face for example; and the reception areas of the electrical connections CEa, CEb, CEc, CEd and communication connections CCa, CCb on the rear face of the shell for example. It will be understood that if the electronic device has a screen, it is appropriate that the transparent area is in correspondence of this screen. Moreover, in accordance with the foregoing, the reception areas cooperate with the connections of the shell in a sealed arrangement. When the device comprises a touch screen, it may be necessary to limit the thickness of the shell at its transparent area for the touch detection to work properly. Referring now to Figure 4 that there is illustrated another example of waterproof shell structure. In this example, the shell 2 comprises at least: - an opening OUV, - an O-ring seal J placed inside the shell 2, between the shell 2 and the APP device, at the periphery of the opening OPEN on a zone of cooperation of the shell and the apparatus, - a film FIL transparent antibacterial protection covering the device at least on a surface in correspondence with the opening OUV. In this embodiment, the opening is advantageously designed to be in correspondence of a part of the surface of the electronic device APP. For example, the opening OUV can have dimensions in correspondence of a screen of the apparatus. The device cooperates on an area, inside the shell and at the periphery of the opening, and this so as to close this opening OUV. This shutter is also sealed by the presence of the seal J to the cooperation zone.

In this way, the user of the APP device can have easier access to the APP device (because it is covered only by the film FIL), allowing in particular to maintain optimal sensitivity for a touch screen of the apparatus. With such an arrangement of the shell, the latter also remains waterproof and antibacterial, notwithstanding the opening OUV.

The support 3 is also waterproof. For this purpose, the electrical and electronic elements are installed in the housing 6, which is a waterproof housing. The term "sealed housing" means a housing preventing the passage of solid and liquid particles inside thereof. For this purpose, the housing 6 may be: - a closed housing, or - an open housing whose opening is closed by the support plate 5. In the latter case, it is necessary to install sealing means , such as an o-ring seal, between the limp 6 and the plate 5. As explained below, the housing 6 comprises electrical elements and electronic modules of the device 1. It is also connected to electrical outputs and communication devices electrically connected to the first Ela, Elb, El c, El d and second E2a, E2b electrodes of the support 3. The electrical outputs can be connected to the electrodes via electrical connections included in the plate 5 so as not to be exposed to possible projections of liquid for example. The shell 2 and the support 3 are therefore sealed and form a sealed assembly when the electrical connections CEa, CEb, CEc, CEd, and / or the communication connections CCa, CCb are respectively in mechanical contact and secured by magnetic attraction with the first Ela, Elb, Elc, Eld and / or second E2a, E2b electrodes.

Referring now to Figure 5 in which there is illustrated an embodiment of the device according to which sealing means are placed at the connections and / or the electrodes of the device to further improve the tightness of the assembly formed by the shell 2 and the support 3 when they are secured. Also, a first seal O-ring JT1 can be arranged at the periphery: - electrical connections CEa, CEb, CEc, CEd; and / or first electrodes Ela, Elb, Elc, Eld. In addition, a second O-ring seal JT2 may be arranged peripherally: - communication connections CC1, CC2; and / or - said second electrodes E2a, E2b. The first joints JT1 or the second joints JT2 are intended to be compressed between the plate 5 of the support 3 and the outer surface of the shell 2 when the connections CEa, CEb, CEc, CEd, CCa, CCb are respectively brought into mechanical contact with the electrodes Ela, Elb, Elc, Eld, E2a, E2b. Thus, the electrical connections formed via these contacts between the connections and the electrodes, are sealed thanks to the insulation implemented by the joints JT1 and / or JT2 once compressed. This sealing of the mechanical contacts of the CEa, CEb, CEc, CEd, CCa and CCb connections and of the Ela, Elb, Elc, Eld, E2a and E2b electrodes further strengthens the overall tightness of the device and makes it all the less subject to electrical malfunctions. Furthermore, the shell 2, according to its closed or open structure, may be composed of an antibacterial material such as silicone mixed with silver particles and / or copper. Thus, the outer surfaces of the shell are antibacterial.

The support 3 is also antibacterial. To do this, the plate 5 may be a metal plate completely covered with a layer of antibacterial material (such as an antibacterial paint comprising particles of silver and / or copper for example). The case can also be made of an antibacterial material. The antibacterial material may be of any type and, for example, of the same type as the shell 2. The shell 2 and the support 3 being antibacterial and waterproof, the assembly they form is waterproof and antibacterial when the electrical connections CEa, CEb, CEc, CEd, and / or the communication connections CCa, CCb, are respectively in mechanical contact, and secured by magnetic attraction, with the first Ela, E lb and / or El c, Eld and / or second E2a, E2b electrodes. In Figure 6, there is illustrated an example of the device 1 in a position where the shell 2 and the support 3 are secured by magnetic attraction via the mechanical contacts of the connections of the shell and the electrodes of the support. In this position, the shell 2 and the support 3 form the aforementioned waterproof and antibacterial assembly. Further, in this position, the mechanical contacts, maintained by the magnetic attraction of at least one pair of connection and a corresponding electrode pair, make it possible to electrically power the APP apparatus and to communicate data with it. latest. By way of example, in such a position a user can use the CLA keyboard on the medium 3 to provide text processing or control data which is sent to the communication interface of the apparatus via the contacts. second electrodes E2a, E2b and communication connections CCa, CCb. In addition, fixing means FIX of the support 3 may be provided for fixing the device 1 to a wall such as a wall, a partition, a piece of furniture or other. The fastening means are, for example, screws, rivets, or the like. Advantageously, the attachment means will be covered by an antibacterial protection, or will be made of an antibacterial material. In addition to being antibacterial, the entire shell 2 and support 3 is waterproof and therefore easy to clean. For example, the device 1 can be vigorously cleaned with water and / or disinfectants, without the risk of damaging the on-board electronics of the device, including the electronic device. The device can be cleaned more effectively without risk of damage, which further improves the health conditions of a patient's environment and, in addition to being already antibacterial, further limits the risk of nosocomial infections. According to the tests, this assembly makes it possible to offer a seal of the device 1 meeting the IP64 and IP65 protection ratings of the International Electrotechnical Commission's IEC 60529 standard. The device 1 furthermore makes it possible: - an automatic supply of the apparatus as soon as the shell is secured to the load support; - a simple and protected fixation of the electronic device; - a connection of ancillary control accessories for more comfort of use.

Referring now to Figure 7 which shows schematically the load carrier with electrical elements and electronic modules that compose it. The first electrodes Ela, Elb, Elc, Eld are connected to an electrical transformation module ALIM of the support 3, housed in the waterproof housing 6. The ALIM module can receive a power supply from: a source SRC of electrical energy such as an electrical installation, an electrical outlet, or other; or an autonomous power source such as a BAT battery.

BAT BATTERY allows to continue to power the device when the shell that hosts is magnetically attached to the support 3, and there is a power failure from the source SRC. On the other hand, the battery can be provided to power the electronic modules of the load support 3.

The ALIM module is designed to transform the power supply received from one of the aforementioned sources into a power supply adapted to the device housed in the hull. As a purely illustrative example, the power supply from the SRC source is an AC power supply (50 Hz) of 220 volts that the ALIM module transforms into a continuous supply of 48 volts and a power between 10 and 60 watts . This transformed power supply is particularly adapted to the device, which can operate optimally, or recharge its own battery via this transformed power supply. The second electrodes E2a, E2b are connected to a communication module COM of the support 3, housed in the sealed housing 6. The module COM can receive, interpret and send data exchanged between the second electrodes E2a, E2b and a connection of communication with an extensive network RES.
