To provide the first possibility of a functional bed - lifting the head section, the node with a belt with a toothed clip 17, the first hook of which is hooked above the bed on the socket 13 of the tube 12, is wrapped around the central part of the tube 26 and the second hook is hooked on the same socket.

The serrated belt assembly 17, the first hook of which is hooked above the bed on the socket 13 of the pipe 15, is wrapped around the central part of the pipe 26 and the second hook is hooked on the same socket. At the free end of the toothed belt assembly, the length of the belt is shortened so that the end of the tube 15 above the bed is at the lowest point. The free end of the toothed belt connecting the tube 15 and 16 was tightened so that the socket end of the tube 16 was raised. In this position, the hinge of the jack 18 is in the extreme position, and the wheel of the jack 19 is on the floor. While the patient 30 is on the sheet 28, which lies on the mattress, which in turn lies on the false bed. The attendant inserts the tube 20 into the free tube of the jack wheel assembly 19 and makes a 100-110 degree turn. The jack wheel rolls over the "dead center" and rests. The dorsal section of the overhead bed rises to a certain angle. The attendant, pulling the free end of the belt attached to the pipe 12, tightens the belt. Turning the tube 20 releases the belt tension on the tube 15. The back section remains raised. The belt on the pipe 15 is reduced in length, and the pipe 15 returns to its original state. The steps are repeated and the back section 23 is lifted to an additional angle. Depending on the seat attachment points chosen and the lengths of the segments, the lever system can provide gear ratios up to the point that a 50 kg attendant can lift the back section for a patient weighing even 300 kg. And this is not the limit. At the same time, the attendant can use his weight for the specified and not make significant physical efforts.

Depending on the weight of the attendant and the weight of the patient, the maximum lifting of the section is carried out in one or more cycles.

The lowering of the section is carried out by the attendant with small physical exertion with both hands. With one hand, the peeler holds the free end of the belt with a toothed clip taut, and with the other, the belt lever is pressed.

When using one volumetric knot, in addition to raising the back section, other sections can also be raised. For example, to raise the femoral section, you can insert a 15 * 15 mm pipe of the bed engagement unit into the inside of the pipe 27 and hook two hooks of the belts connecting with the pipe 15 to the plates on the studs, fixing the position of the femoral bed, use a stand under the bed or improvised objects.

Fixing the position of the section of the overhead bed can be ensured both by fixing the position of the assembly with the belt on a stationary pipe 40 * 20 mm, and by placing hard or soft improvised objects under the raised overhead bed. It is sometimes convenient to have a voluminous, lightweight tube structure that can be placed under a bed raised using knots with a belt. The support under the bed changes its volume within a few tens of seconds, is fixed by tightening two bolts, gaining strength. And it is placed under the raised section of the bed.

On a bed on which a false bed is not installed, it is possible to change the position of the patient by raising part of his body, fixing the mattress attachment point in the selected place, and then placing improvised soft objects under the mattress.

In the case when two volume units with additional elements are installed on the bed, it is possible to lift the patient above the bed to change sheets or mattresses. It is possible to enable the patient to lie on a sheet, as in a hammock. To do this, each end side of the sheet is wound onto a 20 * 20 mm meter pipe and clamped by two sheet attachment points 22, which in turn are connected to pipes 15 and 12.

If the patient is very heavy, then it is most rational to use four volume units with four jacks.

If the side of the sheet is wound onto a 20 * 20 pipe and secured with the sheet attachment points, then the patient can be turned on his side, turned over from his back to his chest and vice versa.

The nodes in Fig. 1 and FIG. 2 nodes can be used for a number of other actions. For example, drape anchors can be used to spread the drape under the patient or ensure that the drape does not wrinkle. These same elements can be used to restrict the movement of a violent patient. Or so that the patient does not throw off the blanket.

Using a comb, the section can be lifted without installing volume units. To do this, the comb axis and the axis of the lever are put on the pin of the bed engagement unit inserted into the corresponding pipe of the overhead bed, the rotation of which ensures the raising of the section. And the lever is rotated by pressing the foot of the attendant on the pipe from the system of levers. Combs can also be used when changing the longitudinal angle of the bed in stages.

In FIG. 3 shows the main variant of the use of the winding mechanism, which is assembled using four main or additional volume units 6 installed at a distance of more than two meters along the bed and more than a meter across the bed. A winding pipe support 32 is installed on each rack 10, consisting of a pipe section 60 * 30 mm 33, to which plates of 2 mm sheet steel are welded, acting as a bearing cage 34 with an inner diameter of 35 mm - 35. Plates of two of the four assemblies of the roll mechanism 32 have holes into which the axles 36 of the eccentric 37 are inserted. A winding tube is inserted into the inner sleeve of two bearings 35 located on one side. The round pipe 38 of the winding pipe is welded with a piece of square pipe 20*20 mm 39, which is inserted into the pipe 38.

An additional advantage of the proposed roller mechanism is the ability to perform complex, usually requiring great physical effort, actions using the sheet on which the patient lies. For example, to turn the patient on the side or from the back to the chest (or vice versa), a 15 * 15 mm square tube is inserted into the tube 39, which is part of the handle, ensuring the rotation of the first tube 38. When the tube rotates, the sheet is wound around the tube 38. The patient turns or flips over. The same manipulation can be used to place various elements under the patient. First of all, a new sheet and a more durable soft element (for example, sheets) needed for more complex manipulations. The use of wrapping a sheet around one long tube (2.5 m long) can be effectively used to transfer a patient from bed to gurney (or other bed) and from gurney to bed. Although in most cases the patient lies on a standard drape that is not wide enough to operate on these tubes, it is possible to move the patient on this standard drape. To do this, the standard sheet is extended using an additional sheet, which is connected to the two ends of the sheet under the patient using pipe segments 20 * 20 mm and sheet attachment points 22. At the same time, to move the patient from the wheelchair to the bed, the volume unit (and the roll mechanism on it) stand as shown in figure 3 - next to the bed. And to move from the bed to the gurney, the pipes 8 must be meter long - the volume units will stand behind the far side of the gurney from the bed.

The use of two long tubes, with a sheet wrapped around them, as shown in Fig. 3, allows you to perform a wide range of maintenance activities. Of the simple important actions, these are actions related to the fight against pressure sores. The attendant can change the position of the patient in a few tens of seconds, without load for himself and comfortably for the patient - by turning the handles. But even a complex action - lifting the patient above the bed on a sheet is not a load action. The node that performs the function of the eccentric 37 must have a moving part (counterweight). In one position of the moving part, the center of gravity of the equivalent eccentric 37 must be on one side of the axis of the eccentric 37, and in another position of the counterweight, the center of gravity of the equivalent eccentric 37 must be on the other side of the axis of the eccentric 37. When the counterweight is in the first position, the eccentric 37 is pressed against pipe 38. This should be at such an arrangement of the axis relative to the point of contact that the rotating pipe 38 in the mode of winding the sheet throws the eccentric 37 away from itself. Then, when the pipe rotates so that the sheet unwinds, the eccentric 37 will jam the pipe 38. That is, in the first position of the counterweight, the sheet can only wind up and stop at a new level. In the second position of the counterweight, if in the initial position the eccentric 37 was not in a state of jamming of the pipe 38, then the pipe 38 will rotate freely in both directions. If the counterweight was in the first position, and the pipe 38 rotated with the load, then after removing the force on the handle, the pipe 38 is wedged by the eccentric 37 and the pipe does not rotate, both with load and without load. If the pipe 38 is in a state of jamming, then the transfer of the counterweight to the second position does not change the state of the pipe 38. When the handle is turned in the direction of winding by several degrees, the pipe 38 and the eccentric 37 are wedged. The eccentric 37 moves away from the pipe 38, and the pipe rotates freely in both sides. The attendant, turning the handle in the direction of unwinding the sheet, lowers the patient onto the bed.

After sequentially rotating the handles of both long tubes, the sheet is wound to the required dimensions, the patient rises above the bed. In some situations, this position is comfortable and useful for the patient. This position is similar to the position of a person on a hammock, but at the same time, the body is straight. This is especially important for people with back problems. If, from the described initial position, a sheet is additionally wound onto one pipe 38, and twisted on the other, the patient will turn around the longitudinal axis of the body. And you can either leave it in the desired position or lower the bed onto the mattress in a position on its side, chest or back.

When using two main and two additional volume units, there is an additional possibility of changing the longitudinal angle of the bed.

After lifting the patient off the bed, you can change the mattress or put on a new sheet. For bathing on the bed, a sheet of waterproof material is placed under the patient. After that, all four sides of the waterproof fabric are wound onto segments of square pipes and clamped with the sheet attachment points 22. The design of the waterproof material, pipes 20 * 20 mm and the sheet attachment points is fixed on the pipe sections connected to the base pipes 4. After the bathing procedure, it is drained water, the construction of waterproof material and pipes is removed and disassembled. Winding mechanisms can be used to change the padded soft elements.

The main element of a wide range of side rails, space restraints, climate control and bed extensions is the side rail assembly. In FIG. 4 shows the side railing assembly 40, consisting of a bent round pipe with a diameter of 20 mm 41 and a square pipe 20 * 20 mm 42 welded together. The pipes have a wall thickness of 1.5 mm. The blank of a round pipe before bending has a length of three quarters of a meter. The outer diameter of the pipe bend 42 is 180 mm. The bent pipe has a symmetrical shape and has external dimensions of 300*180 mm. Pipe 42 has a length of 180 mm, on one side of pipe 42 there are two symmetrically located holes with a diameter of 12 mm. M12 nuts are welded onto the holes. The axes of the M12 nuts are directed parallel to the straight sections of the pipe 41. A bolt with a point at the end 43 is screwed into the nut on the pipe 42.

The base of the side rail, (as well as, or the extension of the bed, or the space limiter) is assembled from two nodes of the side rail 40 and two identical segments of a round pipe with a diameter of 16 mm 44. The folding side rail is assembled from the base of the side rail and two racks of the side rail 45.

Depending on the lengths of the pipes 44 and the fixing points of the side rail brackets 46, the length of the folding side rail can range from 600 mm to more than 2 m. 50 * 25 mm of which is inserted the socket of the side railing bracket 48, which is a piece of pipe 40 * 20 mm and 20 * 20 mm welded together with a welded M12 nut on the hole. Each side rail post and side rail bracket are assembled with M8 bolts passing through the upper holes of the bracket plates 46 and the slot of the post 45. bar 16 * 16 of the bracket 46. The side railing stands securely in a vertical position. If from this position the side railing is pulled upwards by the round pipe, the side railing will rise by 40 mm - until the M8 bolt stops in the opposite rounding of the rack groove. Then, starting to move in a horizontal direction, the side railing is turned by 180 degrees to move to the lower position.

The hinged side guard changes position quickly and easily. But there are situations when it is necessary to fix the side railing in the upper position. To do this, it is enough to insert the M8 bolt into the second (lower) pair of holes in the bracket 46.

The base of the side rail can be used to increase the width of the bed. To do this, instead of the side rail bracket 46, a bent square bar 16 * 16 mm is installed in the socket 48. If the square 16*16 mm is bent by 90 degrees, then the extended part of the bed will lie in the plane of the bed bed. If one base of the side railing is installed on a pair of bent squares 16 * 16, then the bed expands in one direction by a quarter of a meter. If the bar is a quarter meter longer and two side railing bases are installed on a pair of 16 * 16 mm squares, then the expansion in one direction will be half a meter.

If the square 16*16 mm is bent by 60 degrees, then the extended part of the bed will lie at an angle of 30 degrees to the plane of the bed bed. Extending the bed to one side by half a meter (installing two lateral bases) provides one of the most effective procedures for turning the patient from back to chest and vice versa. To do this, on the second (opposite expansion) side of the bed, a second pair of base tubes 4 is installed. The hinge of the jack 18 is installed at the butt against the movable pipe 50*25 mm of the bulk unit 6. The movable tube 50*25 mm of the volume unit is fixed in a horizontal position. To do this, two vertical M12 bolts of the volume unit 6 are screwed into the M12 nuts welded between the horizontal plates until both bolts rest against the pipe 16 and fix it in a horizontal position. The pipe 40*20 mm connecting the hinge of the jack 18 and the wheel assembly of the jack 19 must have a length of less than a meter. The tube 20 may be a meter long if the attendant weighs more than the patient. In this case, the attendant rotates the tube 20 by 110 degrees and the bed is tilted by 30 degrees. If the patient is heavy and the attendant is light, the tube 20 is extended using the articulation part of the executive tubes. Additionally, a sixth type pipe crossing unit and another 40 * 20 mm pipe can be added. Then the attendant, holding the last pipe 40 * 20 mm and simply crouching, will turn the bed with a heavy patient to the required 30 degrees in this case.

For most patients, to return the bed to its original position, it is necessary to return the jack to its original position and the attendant, applying a load of 10-15 kg, will return the bed to its original position. If the patient has a large weight, then in order to return the bed to its original position, a set of elements based on a volume unit is installed on the side of the bed extension, similar to that described above, but pipes 8 are inserted into fixed horizontal sections of pipes 50 * 25 mm of volume node, will have a meter length.

After the bed is rotated 30 degrees relative to the longitudinal axis and the patient lies on his side on the extended part of the bed and his back on the main part of the bed, the attendant turns the patient onto the chest with little physical exertion.

For example, a 57 kg attendant turns a bed with a 160 kg patient with little or no physical exertion in this way. After that, with a hand force of less than 10 kg, the attendant turns the patient from the position on the side to the position on the chest. According to available information, the rollover of such a patient from back to chest in advanced medical institutions is carried out by a well-coordinated team of 5-8 men. (Information on television from the chief physicians of the Moscow City Clinical Hospital No. 40 Protsenko D.N. and City Clinical Hospital No. 15 Vechorko V.I.). Let us briefly note that recently the procedure of turning the patient from the back to the chest (and vice versa) has become an important component of the treatment of coronovirus patients.

Like many other manipulations, turning the patient from the back to the chest can be performed by several different sets of inputs included in the constructor device. Each set has its own advantages over others. Here we indicate the advantages of a set with an extension of the bed with an angle of the extended bed of 30 degrees. This set has the minimum number of input elements. It assembles very quickly - in the initial tens of minutes. Many sets work effectively, but for this, a certain soft element must initially be under the patient. For patients who do not get out of bed themselves, especially when they are heavy, the need to place an additional soft element is a serious problem. And at least changing the sheets is a regular problem. For an extended bed with a turn of the bed, not only is there no need to insert an additional soft element, but this manipulation can be used to insert additional soft elements for effective operation with other sets of device-construction. Or as independent manipulations - changing sheets and mattresses.

The base of the side railing can also be used for a number of sets associated with the installation of three-dimensional structures above the bed bed. In FIG. Figure 4 shows an example of a set of ten side rail bases that provide space limitation above the bed of any bed. At the same time, six bases have a two-meter length, and four (end) meters. One two-meter base is part of a folding fence (bottom in Fig. 4). On the opposite side of the bed, in both sockets of the side rail bracket, instead of the side rail racks, a 15 * 15 mm pipe 8 decimeters long is inserted, on which one two-meter base is put on and fixed, and at a distance of one and a half decimeters the second two-meter base. This vertical pair of two-meter bases is permanently attached to the bed.

Similarly, two pairs of meter bases are fixed at the ends of the bed. The four meter bases are connected to the two 2 meter bases by eight Space Restriction Pipe Connectors at the midpoints of the pipe bends 41. The three 2 meter bases connected using 15*15 mm pipe lengths form the movable space restriction part. In the closing position of the space, two two-meter bases have a horizontal position and are located at a distance of half a meter above the mattress. The third two-meter base is located vertically and is located above the folding side railing. The movable part of the space limiter has articulated joints with a stationary upper two-meter base. In order to provide convenient access to the patient, the folding side rail leans back and the movable part of the space limiter from three two-meter bases rotates. To do this, it is enough for the attendant to apply an effort of 8 kg.

The described space limiter, consisting of ten bases, allows the patient not only to lie on a flat bed, but also to be in a reclining position. It is possible to increase the height of the structure. To increase the height of the space limiter for every third of a meter, four bases must be added - two two meters and one meter each. In these cases, the upper horizontal two-meter bases become stationary. Vertical two-meter bases above the folding side railing become movable. These structures can be the basis for providing a microclimate. There are several options. For example, the effect of a salt cave is provided. Or , it is provided that the medicine is obtained from the air for the whole body, except for the face (head), while the patient breathes air without medicine. It can also provide the possibility of inhalation (aromatherapy) lying on the bed. Another option is to isolate the air mass above the bed from the area outside the bed. To protect the patient from external infection, the air above the bed is pre-disinfected. To protect the surrounding people from infection of the patient, the air is processed after passing through the area above the bed.

It is possible to provide any bed with a Balkan double frame in several sets, all of which use four attachment points to the leg and four third-type pipe crossing points. Eight more pipe crossing nodes are also commonly used. There are several options. There may also be options for sets of pipe sections and pipe joints.

To enable the patient to use the vessel in a sitting position on the bed, it is necessary that a mattress be installed on the bed with a removable section of the mattress in the middle part of the femoral section measuring 360 * 200 mm. The initial position of the patient is the supine position on a flat bed. Under the mattress with a removable section of the mattress there is a bed of the construction device. One of several techniques included in this device-constructor, the femoral section is raised by 45 degrees. At the same time, the end part of the foot bed remains on the bed of a flat bed. The leg section takes a 45 degree angle to the flat bed and 90 degrees to the thigh section. The attendant removes the insert of the mattress with a solid base. In place of the removed part, the vessel is inserted and fixed to the femoral section of the bed. Next, the back section rises 45 degrees. The attendant must ensure that the slip-on bed is securely fastened to the bed. There must also be reliable patient insurance. Near the head end of the bed, on both sides there should be a volume unit 6, with jacks attached to them. Using the technique described above for the lateral tilt of the bed, the bed acquires a longitudinal slope of 45 degrees. The device-designer has the possibility of multi-stage lifting by one serving a small weight of the patient with a large weight. This may take a few minutes. If there are two attendants, then the change in the angle of the bed can occur for several tens of seconds. In this device-designer, the possibility of using two units with electric drives is included, with the use of which many manipulations are carried out efficiently and comfortably. In particular, a change in the longitudinal angle of the bed. To do this, as in the case of lateral tilt described above, the jack hinge is installed as close as possible to the movable pipe of the volume unit, but the pipe 16 must be more than half a meter long. The hinge of the mechanical drive housing is fixed on the pipe 16, and on the pipe between the jack hinge and the jack wheel assembly, it was fixed to the hinge of the mechanical drive running tube. A 15 * 15 mm pipe is inserted into the square pipe of the mechanical drive, which is a working tool put on the output shaft of the electric drive gearbox.

In order to provide the bed with wheels, it is enough to have connecting elements of any wheel (including self-orienting) with a pipe of 40 * 20 mm or 50 * 25 mm and use pipe crossing units of the appropriate type. In order for the patient to move independently on his bed, a pair of self-orienting wheels is installed on the base pipes in the area of one end of the bed. And at the other end, a pair of electrically controlled wheels are installed. An electrically controlled wheel is a wheel with an axis perpendicular to the longitudinal axis of the bed and parallel to the floor, the rotation of which is provided by an electric motor with a gearbox.

The bed movement mechanism provides an opportunity to equip any bed on stationary legs with self-orienting wheels in tens of seconds with a physical load of tens of kg. To minimize transport volume, the casters can be transported separately from the machine base. The basis of the mechanism will occupy a volume of 11 * 7 * 1 dm and weigh about 6 kg. Weight with wheels will be about 10 kg. The movement mechanism can be used both for one bed (for example, at home), and to provide movement for many beds using one mechanism (for example, in a hospital). To prepare the mechanism for a specific bed, pieces of pipe 15 * 15 mm or pieces of square bars 16 * 16 mm are inserted into pipes 700 mm long of the mechanism, to which additional simple pipe parts are attached, which ensures the height of the upper part of the mechanism with an additional structure of 10 - 40 mm below the bottom of the bed. The mechanism rolls under the bed. The attendant inserts into one of the pipes 50 * 25 mm of the mechanism a piece of pipe 40 * 20 mm with a length of at least half a meter. A fifth pipe crossing assembly is put on the transition pipe 40 * 20 mm, into the second pipe of which the execution pipe 40 * 20 mm is inserted and the execution pipe is rotated by 135 degrees. Turning the first 90 degrees raises the top of the mechanism by 75mm and lowers it by 25mm when turning the next 45 degrees, ensuring that the mechanism is securely positioned with the bed on it. Thus, a gap between the bottom of the legs of the bed and the floor from 40 to 10 mm is provided. When using a two-meter execution pipe to raise the bed with a patient weighing together 150 kg, the attendant needs to briefly apply a force of 10 kg. After turning the executive tube, the attendant removes the executive tube and moves the bed like a bed on self-guiding wheels. After the need to transport the bed with the patient has ended, the attendant brings the bed to the place of its stationary location, inserts the execution pipe and makes a reverse turn by 135 degrees. He takes out the pipe. Rolls out the bed movement mechanism.

A screw drive, for example, can be used to change the angle of the executive pipe with a profile of 40*20 mm in those configurations of the constructor device in which the basic working movement of the executive pipe is provided either by pressing the 40*20 mm pipe with the subsequent transfer of force to the executive pipe through a knot with a belt, or when the initial force is provided by the operator's hands using a jack. To do this, the hinge pipe of the drive cage is fixed on a fixed pipe 40 * 20 mm of the corresponding configuration, and the hinge pipe of the running pipe is fixed on the mobile (executive) pipe 40 * 20 mm. A 15*15 mm tube of the screw drive handle is inserted into the 20*20 mm tube of the screw drive. By turning the knob of the screw drive, the angle of the execution tube changes. This use of a screw drive allows you to choose the most convenient gear ratio for the attendant for a particular patient. This is ensured by changing the distance of the running pipe hinge from the executive pipe hinge.

If, instead of the handle of the screw drive, a pipe 15*15 mm of the electric drive is inserted into the pipe 20 * 20 mm of the screw drive, making it impossible to rotate the body of the electric drive, then the angle of the executive pipe will be changed by turning on the electric drive. The role of the use of motors in the construction device has a different emphasis than the role of the conventional use of motors in functional beds. The main purpose of the common use of electric drives is to reduce the load on the attendant. In the device-designer, all operations can be provided with a small load on the attendant, while faster than conventional electric motors, and reducing the load on the attendant is a secondary task. The main task of using electric drives in the device-constructor is the ability for the patient to change his position on his own and provide himself with the necessary procedures. In addition, the device-constructor contains the possibility of assembling rehabilitation equipment, which is assembled using electric drives. The simplest example would be the cyclical movement of a selected section of an overhead bed (or a bed of a mechanical functional bed) within the given angle limits.

The maximum stress on any mechanism used to manipulate the bed occurs when the patient is lifted off the bed. Manipulations are especially difficult when a weakened patient is put on his feet on the bed or next to it, and also sits down on the toilet seat next to the bed. It is particularly difficult in this case to provide comfort for such a patient, associated with the connection of the patient with the power mechanism. The use of straps, similar to parachute attachments, requires rarely achievable skills from the attendant. The need to install belts on a patient lying on the bed, moreover, a weakened patient makes comfortable fastening of the belts almost impossible. Moreover, a parachute suspension from belts is installed only on a person with strong muscles. And if the belts are installed correctly, which can only be done on a strong person involved in the installation, then the belts may not create pain. But for weakened patients weighing more than 60-80 kg, the belts will not only create discomfort, but will also create pain. The patient attachment presented in this invention provides a comfortable connection with the power mechanism even for a weakened patient weighing more than 150 kg and even 200 kg. The design of the patient attachment allows it to be installed on a weakened patient by a light weight attendant. To do this, the leg soft elements are installed on a horizontally lying patient or with an elevated femoral bed, and the chest soft element is installed with the back section maximally raised. Then the patient is placed in a horizontal position, and the chest and leg soft elements are connected with straps with fastex-type latches. Then the back section rises. Using four or six 50 mm wide straps with "pins" at the bottom, the patient harness is connected to the power mechanism.

In order to be able to place the patient next to the bed and/or seat the patient on the toilet seat next to the bed, a two-dimensional hinge assembly of the stand is installed on the top post 11. For heavy patients, it is necessary to additionally strengthen the column 11. It is most effective when used for ceiling or wall support. If it is impossible to use the ceiling or wall as a support, additional pipe crossing units and additional pipe sections must be used to strengthen the rack 11. A half-meter section of a pipe 40*20 mm is inserted into a pipe segment 50*25 mm, located at the bottom on a two-dimensional hinge assembly, on which a pipe segment 50*25 mm is installed, pivotally connected to a pipe 30*30 mm of a screw drive. A 40*20 mm pipe segment is inserted into the 50*25 mm pipe section, located at the top of the two-dimensional hinge assembly, and fixed in its middle part, on which, in the direction from the bed, a 50*25 mm pipe segment is installed, pivotally connected to pipe 25*25 mm screw drive. At the end of a meter pipe, located above the bed, a hook socket assembly is installed, to which straps with “pins” are attached. Four straps are attached to the chest pad when the patient is positioned next to the bed. If the patient needs to be seated on a toilet seat next to the bed, then two additional straps are used that connect the vertical “nests” of the leg soft elements. Servicing with a screw drive handle or with the help of an electric drive changes the angle of a meter pipe 40 * 20 mm. The patient rises above the mattress. Then the attendant, holding the patient, turns him around the vertical axis (which is provided by the vertical axis of the two-dimensional hinge assembly) by 120-140 degrees. The patient, secured with four straps, is placed on his feet next to the bed. The patient, secured with six straps, is led out over a chair or toilet seat. Then, using a screw drive handle or an electric drive, the patient sits on a toilet seat, chair or wheelchair.

The procedure for placing the patient while standing on the bed, on which the Balkan double frame is installed, can be carried out in several ways.

All elements (except for fastening the patient and electric drives) of the proposed device-designer are prepared for the possibility of disinfection by heating.
