    [0002] BED WITH ANGULAR POSITION CONTROL AND ANGULAR POSITION CHANGE PROCEDURE
    [0003]
    [0004] OBJECT OF THE INVENTION
    [0005]
    [0006] The invention, as expressed in the statement of the present specification, refers to a bed with angular position control as well as a procedure of change of angular position, to the function to which it is intended, advantages and characteristics of novelty, which they describe in detail later, that suppose a remarkable improvement of the current state of the technique.
    [0007]
    [0008] The object of the present invention falls, in a bed with angular position control of the type that, intended to procure a change in the zone of maximum pressure or distribution of the pressure of bedded users who can not change themselves by posture by means of. The invention that generates a movement of lateral tilting of the structure on which the bed is supported, presents, among other innovations, the particularity of presenting with a programmable electronic device that provides an automated control of the angular change of position drive, providing remarkable advantages against what is known up to now in the market.
    [0009]
    [0010] FIELD OF APPLICATION OF THE INVENTION
    [0011]
    [0012] The field of application of the present invention is part of the sector of the industry dedicated to the manufacture of resting elements, particularly beds, at the same time encompassing the field of medical, orthopedic and similar technical aid devices and devices.
    [0013]
    [0014] BACKGROUND OF THE INVENTION
    [0015]
    [0016] As is known, people with mobility problems and / or diseases that prevent them from moving by themselves, for example people affected by spinal cord injury, multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), cerebrovascular accident (CVA) , elderly, need help to change their position in bed periodically and frequently, because otherwise they are harmed by the occurrence of pressure ulcers.
    [0017]
    [0018] As an aid to prevent such pressure from causing such ulcers and / or to alleviate the existence thereof when they have already appeared, there are known in the market the so-called beds with angular position control, which, installed on a double frame structure, They incorporate a mechanism that allows to print a lateral swinging movement that causes a variation in the pressure distribution (maximum pressure point) when moving the user's center of gravity. It is usual that the relative position of the patient with respect to the mattress does not vary.
    [0019]
    [0020] Said type of bed, however, has some aspects that can be improved, among which is the difficulty of handling it by the user, since, normally, this has very limited ability to move and, consequently, to operate and manage the movements of the bed independently.
    [0021]
    [0022] That is why, the objective of the present invention focuses on developing a new bed with angular position control of automated operation to avoid as much as possible the disadvantages above of difficulty so you have this type of bed for your users. Another object of the invention is a method of changing the angular position of the bed.
    [0023]
    [0024] On the other hand, and as a reference to the current state of the art, it should be noted that, although it has been pointed out that other beds with angular position control are known, at least on the part of the applicant, the existence of any beds that present some technical and structural characteristics equal or similar to those presented here claimed.
    [0025]
    [0026] EXPLANATION OF THE INVENTION
    [0027]
    [0028] The bed with angular position control with automatic angular movement control that the invention proposes is thus configured as a remarkable novelty within its field of application, the characterizing details that distinguish it conveniently set out in the final claims that accompany the present description.
    [0029]
    [0030] Specifically, what the invention proposes, as indicated above, is a bed with angular position control of the type that has a lateral tilting movement of the structure on which it is supported, in order to ensure a change in the pressures of the intended user, to change the point of maximum pressure over time and thus avoid the generation of sores while improving the rest and circulation of said user, which is normally someone incapable of changing of posture by itself, presenting, among other particularities, that of having a programmable electronic device that provides an automated control of the actuation of the tilting movement.
    [0031] This device allows to incorporate a series of programs so that the bed moves in an autonomous way and changes user pressures comfortably and silently, avoiding the need for such changes to be made by manipulating a caregiver and a helper, both in prevention as in the treatment of pressure ulcers.
    [0032]
    [0033] This automated programmable control therefore provides the following advantages:
    [0034]
    [0035] • It allows to program a continuous movement of tilting of the bed.
    [0036] • Allows you to choose different parameters of the movement, such as the maximum angle of inclination, speed of movement, starting point.
    [0037] • Allows you to set a "delay" or delay to start the movement after x minutes;
    [0038] • Additionally, the electronic control device can incorporate, at least, an input port to connect a switch of which are known so that disabled people can use it without their hands, for example of operation by sight, by sound, by aspiration, by blowing, by sweeping or others; Y
    [0039] • Optionally, the electronic bed control device also has one or more connection inputs to different sensors, strategically incorporated in different parts of the bed or accessories.
    [0040] • Optionally, the electronic control device comprises a wireless communication module such as wifi, bluetooth or radio, in such a way that it can serve as receiver of variables of the user or of the bed that detect said sensors and send them to a local or remote database, as well as it can serve for the control of the bed from other devices, for example from a PC , an electronic tablet or a mobile phone, or a home automation system. This allows, remotely, use and consult data of the bed by a caregiver without having to bother the user or, even, that a caregiver, at a distance, can consult data such as the weight or the history of pressures and movements. of the bed as the user.
    [0041]
    [0042] Preferably, the sensors that, for example, incorporate the bed and that are connected to the electronic control device are:
    [0043]
    [0044] - sensor of abandonment of the bed and / or presence sensor, - weight reader per load cell,
    [0045] - open handrail detector,
    [0046] - actuator position sensor,
    [0047] - pressure sensor,
    [0048] - light detector.
    [0049]
    [0050] It should be noted that, especially, a preferred option of the bed of the invention contemplates the incorporation of a pressure blanket, in which several pressure sensors are strategically distributed that detect the weight of a body on it.
    [0051]
    [0052] In any case, said sensors will be connected to the electronic device. The electronic device can be programmed to communicate the variables captured by the sensors to the caregiver via wireless.
    [0053] In addition, all data can be archived as part of the user's history on the device itself and can even be sent to the caregiver.
    [0054]
    [0055] With this in addition, the electronic control device can interact automatically with the sensors in such a way that, if the sensors capture certain previously programmed variables, the device can send the signal to the mechanism that determines the movement of the bed so that it moves in a certain way.
    [0056]
    [0057] For example, a pressure sensor, (pressure blanket) can capture relative information about whether the user has been in the same position for a long time and, consequently, a part of his body is receiving high pressure for too long. The device can be programmed so that, in such a case, it orders the actuating mechanism of the bed to make a movement to change the high pressure point with the user.
    [0058]
    [0059] Another example is the blocking of the angular position change movement if a bed sensor detects that the handrails are open, thus preventing the movement from causing the user to fall off the bed.
    [0060]
    [0061] In this regard, a procedure for changing the angular position of the bed with the following steps is envisaged.
    [0062]
    [0063] • Programming of the angular position change movement
    [0064] • Capture of variables of the bed and / or user by the sensors
    [0065] • Checking the variables
    [0066] • Execution of the angular position change movement
    [0067] In a preferred embodiment the process has the following stages
    [0068]
    [0069] • Programming of the angular position change movement
    [0070] • Capture through a sensor if the handrails are open or closed
    [0071] • Checking the variables
    [0072] • Execution of the angular position change movement only if the handrails are closed.
    [0073]
    [0074] In another preferred embodiment the process has the following stages
    [0075]
    [0076] • Programming of the angular position change movement
    [0077] • Capture by a pressure blanket the maximum pressure point and the time when the maximum pressure is at that point.
    [0078] • Check if the time values are above a previously programmed maximum time.
    [0079] • Execution of the angular position change movement only if the maximum time has been exceeded.
    [0080]
    [0081] In another preferred embodiment the process has the following stages
    [0082]
    [0083] • Programming of the angular position change movement
    [0084] • Capture through a sensor (for example, a pulse sensor) variable user to determine if he has fallen asleep.
    [0085] • Determine if the captured variables meet the previously established requirements to consider that the user is asleep.
    [0086] • Execution of the angular position change movement only if the user has fallen asleep.
    [0087]
    [0088] For its part, the movement of laterization of the bed, which in a known manner has a support structure comprising a lower frame, usually equipped with wheels, and an upper frame, where the bed frame on which the mattress, which tilts laterally to one side and another pivoting on an axis which, in turn, is coupled to an intermediate support that links it to the lower frame, is determined by a mechanism that, preferably, comprises a single actuator, namely a linear actuator arranged in the central area of the bed structure in such a way that one end is fixed to the lower frame and the other to a side of the upper frame, determining when extending and retracting the descent and elevation of said side, and therefore the tilting movement of said upper frame.
    [0089]
    [0090] Preferably, this linear actuator is a direct actuator, but optionally may comprise a connecting rod interposed in its attachment to the upper frame.
    [0091]
    [0092] The invention provides, however, other optional embodiments, for example in that the mechanism comprises an arc on which the axis of the upper frame slides and rotates, or in which the mechanism comprises a motor whose transmission axis is linked to the axis of the upper frame to make it rotate several degrees to one side and another.
    [0093]
    [0094] The described bed with automatic angular position control consists, then, in an innovative structure of characteristics unknown until now for the purpose for which it is intended, reasons that together with its practical use, provide it with sufficient grounds to obtain the privilege of exclusivity what is requested.

    [0109]
    [0110] PREFERRED EMBODIMENT OF THE INVENTION
    [0111]
    [0112] In view of the aforementioned figures, and in accordance with the numbering adopted, various examples of non-limiting embodiment of the bed with angular position control can be observed, which comprises the parts and elements that are indicated and described in detail then.
    [0113]
    [0114] Thus, according to Figure 1, it can be seen how the bed (1) of the invention, is configured from a support structure formed by a lower frame (2), usually equipped with wheels (3), and a frame upper (4), which integrates the mattress, which pivots on a central axis (5) coupled to an intermediate support (6) that links it to the lower frame (2) and arranged longitudinally to the bed, so that the upper frame (4) presents a movement of angular change of position, that is to say, tilting to one side and the other, which is determined by a mechanism (7) that, in an innovative way, is automatically activated through a electronic device (8) with programmable microprocessor, with which it is connected by cable or wirelessly, which allows to control the movement of the bed autonomously, as programmed, so that it performs different actions, for example a continuous movement, certain angle of maximum inclination, speed of movement, starting point "delay" so that movement starts, etc.
    [0115]
    [0116] Its own, the electronic device (8) incorporates at least one input port for connecting an external switch (9) operating without hands, for example by sight, by sound, by aspiration, by blow, by sweep or by others.
    [0117]
    [0118] Preferably, the electronic device (8) has one or more sensor connection inputs (10) incorporated in the bed (1) and / or in accessory elements (11) thereof, for example, sensor for leaving the bed and / o presence sensor, weight reader per load cell, open handrail detector, actuator position sensor, pressure sensor, light detector, so that said device receives and records different variables of the bed itself and / or of the user susceptible to take into account for its programming.
    [0119]
    [0120] In the main embodiment, the bed (1) comprises an accessory element (11) consisting of a pressure blanket equipped with several pressure sensors (10) strategically distributed in it that detect the weight of a body on it, to be able to program the electronic device (8) in such a way as to drive the mechanism (7) after a certain period of time without variation in the received pressure.
    [0121]
    [0122] Also preferably the bed (1) incorporates an open handrail sensor (10), to program the electronic device (8) to block the movement of angular change of the mechanism (7) with the handrail (12) open .
    [0123] In any case, advantageously, the electronic device (8) also incorporates a wireless communication module such as via wifi, bluetooth or radio, for connection with other local or remote devices, for example a PC, an electronic tablet or a mobile phone , to access the information that registers and / or control its remote operation.
    [0124]
    [0125] On the other hand, according to Figure 2-A, it can be seen how, preferably, the mechanism (7) that determines the angular position movement of the bed (1), comprises a single actuator, which consists of an actuator linear (71) arranged in the central area of the support structure of the bed (1) with one fixed end in the lower frame (2) and the other to a side of the upper frame (4), determining, as shown 2-B, when extending and retracting the descent and elevation of said lateral, and therefore the tilting movement of said upper frame (4).
    [0126]
    [0127] In Figures 3-A and 3-B another embodiment is observed in which the linear actuator (71) incorporates a connecting rod (72) interposed in its attachment to the upper frame (4).
    [0128]
    [0129] For its part, the figures number 4-A and 4-B presents another option of alternative embodiment of the bed (1) in which the mechanism (7) comprises an arc rail (73) where it slides by rotating the upper frame ( 4).
    [0130]
    [0131] Finally in the figures number 5-A and 5-B another option of realization of the bed (1) is observed where the mechanism (7) comprises a motor (74) associated with the axis (5) in which the upper frame pivots (4) ).
    [0132] Having sufficiently described the nature of the present invention, as well as the way of putting it into practice, it is not considered necessary to extend its explanation so that any expert in the field understands its scope and the advantages derived therefrom, stating that, within its essentiality, it may be carried out in other modes of realization that differ in detail from that indicated by way of example, and to which it will also achieve the protection that is sought provided that it is not altered, changes or modifies its fundamental principle .
