Device for facilitating patient getting up from the adjustable bed

The technical solution relates to a device for facilitating the patient's getting up from the adjustable bed.

BACKGROUND OF THE INVENTION

At present, the bedside patients use the most commonly available supports, which are the bed side walls themselves. These are most often attached from both outer sides of the mattress platform to the back and calf part for split siderails and to the actual mattress platform frame for solid siderails. The siderails are most often shaped so that their outer shape allows the siderail to be gripped and used as a stand-up support. The stand-up support is used to support the stand, which is attached to the back panel, which is positioned to its maximum position before starting to get up. By this positioning, the patient is brought to a sitting position and the siderail is then used to complete the standing up. However, this principle is not advantageous since the patient is supported by only one point completely outside the area close to the center of gravity of the patient. The siderail is in a completely unfavorable position for supporting with only one hand.

Another known solution complements the support side with the so-called rising handrail, which forms a second support point when the patient gets up from the bed. The handrail is most often located under the loading surface and is pushed out of the loading surface by means of a pull-out mechanism and brought into a usable position by rotary movements. The disadvantage of this solution is the collision conditions of the handrail with the surrounding siderails, a complicated ejection mechanism, often a very difficult construction of the mechanism to ensure full compliance with the normative requirements for bed construction, and last but not least the initial disadvantage of the handrail under the loading area before erection. In most cases, the availability of the folding handle mechanism under the mattress platform is completely beyond the reach of patients.

Another known solution extends to the use of the aforementioned handrail with a control element which allows the height adjustment of the mattress platform during the patient standing up process. The disadvantage of this solution is that the patient seated with the full weight on the bed is lifted together with the mattress platform and, in order to get up, he must continually move closer to the edge of the mattress platform during the lift of the mattress platform. At the moment, the handrail does not fully fulfill its role as it is always in the same position with the patient. Getting up is therefore extremely physically demanding.

The last known principle of how to support a patient when getting up is the cooperation of the nursing staff during getting up. In such cases, the nursing staff is the supportive and often the most effective support for getting up. The disadvantage is the enormous burden on the nursing staff, the very difficult access to the patient and the very difficult grip that would not adversely affect the patient's health.

The essence of the technical solution

The aforementioned drawbacks are eliminated by a device for facilitating the patient's getting up from the adjustable bed, according to the present invention, which consists of a bed surface with a right side edge and a left side edge intended to exit the bed. The loading area including the side edges is provided with a mattress and a siderail. It is further provided with a handrail which is provided with an electronic control element in the handle of the handrail for positioning the loading surface by means of columns connected to the central control unit for controlling the lift of the columns provided with an electronic position sensing element. The device preferably has an electronic control element positioned adjacent to the handle of the handle. The device preferably has an electronic control element located on the integrated sidewalls. The device preferably has an electronic control element located on a nurse, telescopic or patient controller.

In the basic position, the bed surface is in its minimum position; one side edge of the loading area is at the height Vlmin above the floor, as well as the other side edge, which is at the height V2min

Above the floor. In the basic position Vlmin - V2min. Activation of the actuator starts the movement of the loading surface or its side edges. The other edge of the mattress platform begins to move at the maximum possible speed of the lifting mechanism to the maximum position of the mattress platform at lateral tilt. At the same time, the first edge of the mattress platform begins to move upward to the minimum lateral tilt position at the maximum stroke of that mattress platform. The speed of movement of the mattress platform is determined by the ratio of the length of the trajectories T1 and T2 of the movements of both edges of the mattress platform in the appropriate positioning direction. The speed of movement of the edge of the mattress platform on the side where the patient will exit is reduced by such that both edges of the mattress platform reach their desired height at the same time possible. The TI trajectory shows the movement of the edge of the mattress platform where the patient does not exit. The T2 trajectory shows the movement of the edge of the mattress platform where the patient will exit the bed. The position of the mattress platform A shows the minimum position of the mattress platform as opposed to the position B showing the maximum position of the mattress platform without positioning into the lateral tilt. The C-position of the mattress platform shows the position of the mattress platform at the end of the movement to facilitate patient getting up from the beds. The actuator is comprised of a pair of buttons that can be positioned on the integrated sidewalls, a nurse, a telescopic or a patient controller, or most preferably in the handle of the handrail to assist the patient when standing up. The handle can be attached to the edge of the loading area or integrated into the folding side panels. The handle of the handle is equipped with electrical controls enabling the central control unit to start or end the positioning sequence of the bed surface movements to facilitate the patient's getting out of the bed. The movement of the mattress platform is only possible on beds equipped with any positioning mechanism which allows the mattress platform to be positioned parallel to the lateral tilt while the mattress platform is raised. Variable control of the ejection speed of the bed supports is necessary to achieve such movement. The support of the loading area can be linear electric poles, lever lift mechanism, hydraulic pistons, etc.

The trajectory of the movement of the bed when the patient gets up is formed by its side edges, which move relative to each other when getting up and sitting down. One of the edges of the mattress platform extends from its minimum position above the floor up to its maximum position at full lateral tilt and maximum lift of the mattress platform in the direction of exit from the bed. The two edges of the mattress platform perform this movement in parallel at a speed relative to each other so that they reach their end positions at the same time as possible. The actual calculation of the movement speeds of the individual edges of the loading surface is performed on the basis of the current positions of the supporting columns by means of the central control unit for controlling the lifting of the columns provided with an electronic position sensing element.

The movement of the mattress platform for comfortable sitting on the bed is analogous to the movement for easy getting up from the bed.

The uniqueness of this solution lies in its construction and connection with the central control unit, which allows positioning of the loading surface in a manner in which the loading surface is simultaneously raised and deflected to the right or left lateral tilt. During this movement, all parts of the mattress platform are deflected and raised in the patient's rising direction. Thus, the back side is deflected, which serves as one of the grasping points when getting up and further deflected, for example, a handle for easy getting up. The handrail and siderails are deflected outside the plan view of the loading area and are thus advanced in front of the patient. With the simultaneous lifting and lateral tilt of the mattress platform, the entire back of the pelvis and thigh muscles of the standing patient are constantly supported in the rising direction. Its center of gravity is gradually deflected outside the plan view of the bed surface, thereby transferring the bulk of the patient's weight to his own limbs. The patient stands firmly on his feet before the lifting and tilting movement of the mattress platform is complete. Throughout the process of getting up, the patient only corrects the movement of his body through the handrail and back siderail.

The above-described movement is controlled by means of electrical controls located on the integrated siderails, the nurse, the telescopic or the patient control, or most preferably in the handle of the handrail to assist the patient when standing up. By the above movement, the handle can be swiveled for easy getting out of the bed projection and can easily get up. By the above-mentioned movement, the patient's center of gravity is deflected during an upset procedure outside the attic, although the patient is constantly supported by the bed surface. In the final phase of the stroke, the patient's entire weight is already transferred to his / her feet, which are gradually loaded with this weight. At all times, the patient holds a handrail that is in an ideal ergonomic position. Upon completion of the movement, the handle is only released and leaves the bed. The handrail is accessible for the entire time of the standing up movement and it supports him. Throughout the upset movement, the mattress platform is positioned so that it is constantly supporting the back of the patient's buttocks and thighs. As the patient gradually straightens up, the bed surface constantly supports him.

Example of technical solution

The device according to FIGS. 1, 2, 3, 4, 5 consists of a mattress platform 1 with a lateral edge 3 and a lateral edge 4. The mattress platform 1, including the lateral edges 3 and 4, is provided with a mattress 2. The mattress platform 1 is further provided with a handle 6, which may be equipped with an electronic control element 2 for positioning the mattress platform 1 to a position facilitating the patient's getting up from the bed. In the basic position, the bed area of 1 bed is in its minimum position, ie. the edge 3 of the mattress platform 1 is at a height Vlmin above the floor 8 as well as an edge 4 which is at a height V2min above the floor 8. In the initial position Vlmin = V2min. By actuating the control element 7, the movement of the mattress platform 1 or its lateral edges 3 and 4, respectively, begins to move the mattress platform edge 1 with maximum possible speed by means of a column S1 to the maximum position of the mattress platform even at lateral tilt. At the same time, the edge 3 of the mattress platform 1 begins to move upwards to the minimum lateral tilt position with the columns 2 and 3 at maximum lift of the mattress platform 1. The speed of the edge 3 of the mattress platform 1 is determined by 4 in the appropriate positioning direction. The speed of movement of the edge 3 of the mattress platform 1 is reduced by such that both the edges 3 and 4 of the mattress platform 1 reach their desired height at the same time possible. The trajectory T1 shows the movement of the edge 4 of the mattress platform i, the trajectory T2 shows the movement of the edge 3 of the mattress platform i. The position A of the mattress platform 1 shows the minimum position of the mattress platform 1. Position C of the mattress platform shows the position of the mattress platform even at the end of the movement to facilitate patient getting up from the beds. The current lateral tilt of the mattress platform is indicated by the letter a.

The most frequently used solution is the connection of the chassis and the loading area and bed by means of linear columns S1, S2, and S3. To achieve the required movement, it is necessary to use at least three masts, which are located between the bed and bed and the chassis. Usually, two columns are side by side in the foot part of the bed (under the thighs) and one column in the head part of the bed (under the back). These columns S1, S2 and S3 are connected by supply and communication wires to the central control unit. It is connected to the mains and contains the main power and control part of the electronics. Various types of controllers are then connected to this central control unit to provide information transfer between the user and the central control unit. These controls can be equipped with control buttons or touch screens and a variety of different display units.

The proposed solution is very advantageous in connection with the handrail 6 for easy standing which is located on the edge of the bed or which extends from the side of the bed 5. For example, two handles 6 are located on the bed, one on the left side and the other on the right side of the bed. Each of these handles 6 is fitted with two buttons. One for lifting the platform even when getting up and the other for lowering the platform even when sitting on the bed. These controls in the handrails 6 for easy getting up are connected to a central control unit which evaluates their commands. These controls must be connected to the central control unit in parallel, as the button is pushed up on each side

If the button on the left side of the bed is pressed, the movement of the mattress platform 1, which is suitable for disembarking or disengaging, starts. getting on the bed from his left side. In the case of pressing the button on the right side, this is analogous except that a suitable movement of the mattress platform 1 for the erection and / or lift-up is started. sitting on the bed from the right side of the bed.

The actual movement of the loading surface i is formed by a combination of column movements, which connect the loading surface I with the chassis. The sequence of movements is dependent on the design of the bed, the limiting conditions of the movements, ie conditions which prevent the collision of the individual moving parts with the static parts, eg the loading surface I hits the chassis etc.

The resulting movement can be achieved provided that the current position of the mattress platform 1 is known. All lift columns S1, S2 and S3 are equipped with an electronic position sensing element, and therefore their current position of extension or extension is known at any time. retract. The loading surface 1 is supported, for example, by 3 columns, two supporting it in the leg part under the thighs and one in the center under the back panel. With this column arrangement, the loading surface 1 can be tilted upside down / legs upwards and vice versa The columns S1 and S2 below the thigh section are synchronously retracted, unlike the S3 under the back, which is extended and vice versa. Furthermore, the loading surface I can be tilted to the sides, i.e. the side surface. to the left 4 resp. This movement is caused by the asynchronous movement of the columns S1 and S2 below the thigh portion, one of which is retracted and the other extends, the column S3 under the back portion remaining in position. The control unit controls the movements of all columns based on operator action by means of the controls 2 on the controls or on the handle 6 for easy getting up.

Example for the mattress platform I in the lowest possible position A. At this point, the patient wants to get up from the edge of the 3 bed and therefore presses the up button on the handle 6 for easy standing on this side. The control unit receives this information and evaluates the current position of the loading area I by means of the electronic column position sensing device S1. S2 and S3. The action hit came from the actuator 7, from the edge 3 of the mattress platform I, and therefore a sequence of movements will follow that will facilitate the patient's getting up on the right side of the bed. The central control unit evaluates the current position of the far left column S1. under the thigh part, from the side on which the patient wants to get up. The control unit knows the current position of the column S1 by means of an electronic position sensing element, which means that the column S1 must be extended to its maximum position. The extension length is calculated by the difference between the maximum and the current position. The right column S2 is then calculated. Again, its current position is determined, which is subtracted from its maximum position at maximum tilt and lift of the mattress platform I. This gives the length of the ejection path of the right column S2. Subsequently, the calculation is continued for the middle column S3. The current position of the S3 column is known, so that the end position is the middle position between the maximum extended column S1 and the maximum extended column S2 at full tilt of the loading area L The current position is subtracted from this position, thus knowing the extension length for S3. The column S1 is then extended at maximum speed. This max. Speed is the ejection reference speed, which is dependent on the load on the loading surface I. Further, the central control unit extends the columns S2 and S3 in parallel at partial speed ratios so that all three columns S1, S2 and S3 reach their end position at the same time.

The bed area I of the bed is tilted to both sides, depending on the patient's needs, on which side of the bed he wants to get up. When positioning with the controls on the right side of the bed, i.e., the rising handle 6, with the actuator 7 in the side 5, the right edge 3 is down, the left edge 4 is up, and the patient exits to the right. If it is positioned by the controls on the left side of the bed, the output from the mattress platform I is made on the left side.
