    [0002] NURSING CALL DEVICE FOR HOSPITAL ROOMS
    [0004] TECHNICAL SECTOR
    [0006] The present invention refers to a nursing call device for hospital rooms and the like, specifically to the set formed by the call device itself and the wall base through which the device is connected to the internal communications network. of the hospital or facility in question.
    [0008] The object of the invention is to provide a device with simpler means of connection to the wall base, without polarity, easy and quick to plug / unplug, all with a more secure structure, which prevents its breakage against stresses in the cable from different angles, being its system for the transmission of a large number of types of actions.
    [0010] BACKGROUND OF THE INVENTION
    [0012] Within the scope of practical application of the invention, among the numerous elements that a hospital room has, are those intended for making a call to the infirmary in charge of providing care to the patient housed in the room.
    [0014] In general, the aforementioned nursing call system consists of a call element itself, and known in the hospital environment as a "call bulb" materialized in a wired command with the corresponding call button, as well as optionally with buttons for turning lights on and off, as well as other numerous and varied functions, a control that is linked to a cable destined to be connected to a "wall base" through which it is connected to the hospital's communications system.
    [0016] The means that are used to date to carry out the connection of both Elements are materialized in a pair of male-female connectors, which, although they fulfill the function for which they were intended, in practice present a series of drawbacks, including the following:
    [0018] • It has polarity, that is, complementary parts of both connectors must be matched precisely, making insertion difficult for personnel not trained for this purpose.
    [0020] • They require multiple contacts because it is necessary to use a conductor for each action of the pear, in addition to a conductor common to all of them, which entails a significant limitation in the number of available actions. Finally, it is necessary to incorporate an additional conductor that, together with the common one, transmits the operating voltage of the pear elements from the base.
    [0022] • It is a system prone to breakage, since it is subjected to mechanical stress from a wide variety of angles.
    [0024] DESCRIPTION OF THE INVENTION
    [0026] The nursing call device for hospital rooms and the like that is advocated fully satisfactorily solves the aforementioned problems, based on a simple but effective solution.
    [0028] For this, and more specifically, the device of the invention, starting from the structure described above, in which a wall base and a device or call bulb provided with means of connection to said base participate, the invention centers a of its main characteristics in the fact that connection means without polarity are proposed, by virtue of a cylindrical connection system with magnetic connectors, which significantly facilitates the connection maneuvers, which can be carried out in any angular position of the connector element in addition to supplying connection means in which tongue and groove elements do not participate, susceptible to breakage if the cable is subjected to stresses that are not perfectly axial, which is usually quite common.
    [0030] In this way, in the worst case, when there is excessive tension on the pear cable call, for example with a lateral force component, the device would simply end up disconnecting in case of exceeding the attractive force of the complementary magnets that participate in the connection, without causing any damage to the system.
    [0032] On the other hand, the electrical contacts will materialize in movable terminals against the tension of the respective springs that ensure the pressure necessary for said function.
    [0034] According to another of the characteristics of the invention, it has been foreseen to reduce the number of internal cables that participate in the connection cable from the call bulb to the wall base, so that exclusively two conductors are used, sufficient to power the call bulb electrically, and transmit through them the different identifying signals of the push buttons provided in said bulb.
    [0036] For this, it has been foreseen that the digital pulses (1 and logical 0) of the wall-pear base intercommunication are added to the continuous supply voltage. These pulses are part of a communication protocol previously established and with which the operating states of the system are defined.
    [0038] As for the wall base, it will establish an electrical power supply circuit associated with the two interconnection connectors with the pear, in combination with a turntable or circuit designed to separate the direct current power signals from the signaling of control, counting for this with a control processor that through an interface with the bus and a regenerator of pulses from the pear allows to interpret the signals based on electrical pulses equivalent to logical 1 and 0 organized according to a protocol previously established, so that they are the basis of a state machine under whose principle the system works, so that the interface with the bus makes compatible the impedances of the control processor and that of the wall-pear base connecting cable, while the regenerator of pulses conforms the signals coming from the pear so that they are intelligible by the control processor, which generates the voltages towards the outside (s internal communications system of the hospital), coming from the pushbuttons activated in the pear after decoding, being able to simultaneously generate alarms or warnings through light-emitting diodes.
    [0039] For its part, the female connector that is located on the wall base, from its two terminals allows the continuous supply voltage of the pear to be sent through it, as well as to receive the digital signals corresponding to the digital communication protocol pear-wall base.
    [0041] Regarding the electrical structure of the call bulb, it is very similar to that of the wall base, also incorporating an electrical supply circuit associated with the two interconnection connectors with the wall base, in combination with a turntable or circuit designed to separate the DC power supply signals from the control signaling, counting for this with a control processor that, through an interface with the bus and a regenerator of pulses coming from the pear, allows encoding and sending the signals to base of electrical pulses equivalent to logical 1 and 0 organized according to a previously established protocol, so that they are the base of a state machine under whose principle the system works, so that the interface with the bus makes the impedances of the processor compatible control and that of the pear-base wall junction cable, while the pulse regenerator shapes the signals from the base so that they are int selectable by the control processor, which reads the pushbuttons actuated by the user to carry out maneuvers (nurse call, lights on or off, etc.), being able to signal alarms or warnings through light-emitting diodes.
    [0043] In this way, a simpler device is achieved, easy to connect and disconnect, in which fewer cables participate, all with a more secure structure, which prevents its breakage against stresses in the cable from different angles.
    [0045] DESCRIPTION OF THE DRAWINGS
    [0047] To complement the description that is going to be made below and with the aim of helping a better understanding of the characteristics of the invention, according to a preferred example of a practical embodiment thereof, a set of drawings is attached as an integral part of said description. where, with an illustrative and non-limiting nature, the following has been represented:
    [0049] Figure 1.- Shows a front elevation view of the two main elements that they participate in a nursing call device for hospital rooms and the like made in accordance with the object of the present invention.
    [0051] Figure 2.- Shows an exploded detail of the connector used in the device of the invention.
    [0053] Figure 3.- Shows a block diagram of the electronics provided on the wall base.
    [0055] Figure 4.- Shows, finally, a block diagram of the electronics provided for the call button.
    [0057] PREFERRED EMBODIMENT OF THE INVENTION
    [0059] In view of the figures outlined, it can be seen how the nursing call device for hospital rooms and the like of the invention is constituted, as is conventional, from a call bulb (1), and a wall base ( 2), counting the call bulb (1) with an interface in which a series of buttons (3 ') participate for different functions, a device that is connected to the wall base (2) through a cable (4) of the order of one meter, finished off in the corresponding male connector (5), complementary to a female connector (6) provided on the wall base (2), wall base (2) capable of additionally incorporating call buttons (3) nursing, call cancellation, or other functions.
    [0061] Well, in accordance with the essence of the invention, it has been foreseen that in the cable (4) connecting the call bulb (1) to the wall base (2) exclusively two conductors participate, both for power and for communication, so that the means of connecting the male connector (5) to the female connector (6) are embodied in a cylindrical connection system with magnetic connectors, as shown in detail in figure 2, connection system in which the angular position of the male connector (5) is indifferent when connecting it to the female connector (6), making the connection maneuver much easier, so that magnets (7) of opposite polarity will be established between both connectors, as well as contacts associated with each of the two conductive cables or wires materialized in terminals (8-8 ') movable against the voltage of the respective springs that ensure the pressure necessary for said function.
    [0063] As can be seen in figure 3, the wall base (2), associated with the female connector (6) will include a turner (9), materialized in a circuit that works as a very high value inductance and that allows, consequently, separate the direct current signals from the outside through the supply voltage input (10).
    [0065] A supply circuit (11) will also be connected to said supply voltage input, made up of the electronic components necessary to reduce and stabilize the operating voltage of the rest of the components of the functional element.
    [0067] The wall base (2) has a control processor (12), materialized in a commercial microprocessor that generates and receives the intercommunication data with the pear. They are made up of a series of electrical pulses equivalent to logical 1s and 0s, organized according to a previously established protocol, so that they are the basis of a state machine under whose principle the system works.
    [0069] The control processor (12) is interconnected with an interface with the bus (13) and a pulse regenerator (14). The first makes compatible the impedances of the control processor and that of the wall-pear base connecting cable, while the second conforms the signals from the ringing bulb (1) so that they are intelligible by the control processor (12).
    [0071] The control processor (12) generates the voltages to the outside (16) from the pushbuttons (3) actuated on the bulb after decoding the pushbutton-actuation requested-output terminal in which a voltage must be generated for indication of actuation on a pear button.
    [0073] Said processor is additionally capable of signaling alarms or warnings through light-emitting diodes (15).
    [0075] On the other hand, the interface with the bus (13) is materialized in a circuit that makes the impedances of the control processor (12) compatible and that of the cable (4) connecting the base wall-pear (twenty-one). Indeed, the impedance of the cable is of the order of 120 Ohm, a value that, for most commercial processors, is too low, so that the direct processor-cable connection could not be made.
    [0077] As for the pulse regenerator (14), as mentioned previously, in the cable (4) connecting the pear-wall base (1-2) pulses with an amplitude lower than that necessary for a correct distinction are used. between 0 and 1 by the control processor (12). The pulse regenerator (14) recovers the signal, adapting both its amplitude and its shape to the needs of the control processor.
    [0079] From this structuring, and by means of the female connector (6), both the continuous power supply voltage of the bulb and the digital signals corresponding to the wall-base digital communication protocol are sent through the same two-conductor cable.
    [0081] Finally, and with regard to the electrical structure of the pear, shown in figure 4, associated with the magnetic male connector (5) by means of the corresponding two-conductor cable (4), through which the direct voltage of pear feed as the digital signals corresponding to the pear-wall base digital communication protocol.
    [0083] Said call bulb includes a turntable (9 '), materialized in a circuit that functions as a very high value inductance and that consequently allows the separation of direct current signals from the wall base (2) , of the control signaling.
    [0085] A supply circuit (11 ') will also be connected to said supply voltage input, made up of the electronic components necessary to reduce and stabilize the operating voltage of the rest of the components of the functional element.
    [0087] The pear (1) includes a control processor (12 '), materialized in a commercial microprocessor that generates and receives the intercommunication data with the wall base (2). Said intercommunication data is made up of a series of electrical pulses equivalent to logical 1s and 0s, organized according to a previously established protocol, in such a way that they are the basis of a state machine under whose principle the system works.
    [0089] The control processor (12 ') is interconnected with an interface with the bus (13') and a regenerator of pulses (14 ') coming from the base, so that the first one matches the impedances of the control processor and that of the cable. (4) wall-pear base junction, while the second forms the signals from the base so that they are intelligible by the control processor (12 ').
    [0091] The control processor (12 ') reads the buttons (3') actuated by the user to perform maneuvers.
    [0093] Finally, this processor is capable of signaling alarms or warnings through light-emitting diodes (15 ').
    [0095] For its part, the interface with the bus (13 ') consists of a circuit that makes the impedances of the control processor (12') compatible with that of the wall-pear base junction cable (4).
    [0097] The impedance of the cable is of the order of 120 Ohm, a value that, for most commercial processors, is too low, so the direct processor-cable connection could not be made.
    [0099] As for the regenerator of pulses (14 ') coming from the pear, say that, in the connection cable pear-wall base, pulses with an amplitude lower than that necessary for a correct distinction between 0 and 1 by the processor are used. control (12 '). The pulse regenerator (14 ') recovers the signal, adapting both its amplitude and its shape to the needs of the control processor.
