Description

TECHNICAL FIELD

BACKGROUND OF THE INVENTION The invention relates to beds for the care of patients, devices for raising patients in beds, and more particularly devices for turning patients, turning them around the longitudinal axis of the body.

TECHNICAL LEVEL

The present invention relates to a body-turning device for patients who, while lying down, are not able to independently turn their body from one position to another. This device can help prevent bedsores. The structure of the device shall consist of at least the following components: a frame for attaching the bed to its back and its sides, fixed to the bed or to the floor; swivel-mounted frame bars to this frame; pivoting pulleys with rolls of cloth on the said rods; as well as other drive coupling and fastening elements for assembling the device components; and drive control unit. The device may raise the upper body of the patient (i.e., the patient may be in a semi-lying or semi-sitting position); the device also allows the patient to be placed in a semi-sitting position. The design of this device allows the patient to be tilted with respect to his / her body center of gravity and to estimate the physiologically most comfortable maximum amplitude of movement of the body's center of gravity, ie: the device enables different body positions and translations. The device is not designed to be used: it can be used by a single person caring for a patient. When folded, the device takes up little space and is easy to transport. The device of the present invention does not require much space around the bed, in other embodiments it does not even require a floor around (under the bed) suitable for virtually any type of bed design.

US2008301873A 1 (published December 11, 2008) discloses a design of a patient care device wherein the tissue (on which the patient is lying) pulls well above the bed, the device itself being large, inconvenient to transport. Because of the high altitude, it may be difficult to place the device on the bed because of the medical equipment that may surround the patient's bed, or simply the small space around the bed. To properly place the unit in this case to the bed requires a large space near the bed as well as some floor space. This may cause inconvenience when using this device. Furthermore, the document does not mention anything about the possibility of folding such a device for transportation.

US5327593 (published July 12, 1994) mentions a device similar to US2008301873 with similar drawbacks, which requires the entire space and floor around the bed to operate the device. Such a device would be even more complicated to use in small spaces.

US 3905055A (published September 16, 1975) and US4843665A (published July 4, 1989) provide structures for a patient-gating device that do not occupy a large amount of space around the bed, but the structures clearly show that the mounts are more stationary, often removing and moving the devices to another bed is difficult. Also, both devices do not have the ability to rotate different areas of the body at different amplitudes. Also, these devices cannot be used to place the patient.

US5054140A (published October 8, 1991) provides a patient care device that is easy to mount on a bed, does not take up space around the bed, but the design shows that the device cannot be folded for convenient transportation, nor is it intended for different patient placement. apply different amplitude cloth pulling motion to body locations.

In summary, the following proximate analogues have the following disadvantages:

- the device occupies a large amount of space and space around the bed, which may make it difficult to secure the device for use; the device used may interfere with other medical equipment;

- the device is very difficult or impossible to fold for easy transport;

- complex preparation of the device for use, followed by complex preparation for transportation;

- the device cannot transform into a semi-seated patient when the patient is placed;

- the device cannot apply different amplitudes, pulls of force cloth to different areas of the patient's body, which may cause discomfort to the patient being converted.

In the following, this description provides a technical solution that does not have the drawbacks listed above.

THE SUBSTANCE OF THE INVENTION

PREFERRED EMBODIMENTS

If a patient lying on the bed is unable to turn his or her body, circulatory conditions may be impaired in the patient's long pressed beds. Converting the patient's body is therefore an important task. Properly transforming a patient's body requires a great deal of physical strength, which is why one person is often unable to do so. There are many ways to prevent bedsores, but the most effective way is to place the patient on the other side of the body in a timely and appropriate manner. Various devices are being developed to accomplish this task. This description provides a device (1) for turning the patient on the bed to the other side. As used herein, the term turning to the other side means tilting or rotating the patient's body along its axis: in some cases, it may include tilting from one side to the side, sideways to the back, and / or other changes to the patient's plane conditions for the release of former trapped body parts to restore normal blood flow to the former trapped body. The present invention relates to a new embodiment of the bedside device (1). the device (1) consists of at least the following parts and elements:

- a frame (2) for attaching to the end of the bed and to a portion of the sides of the bed, wherein the frame rods (3) are pivotally mounted to the frame (2);

- frame rods (3) for transmitting mechanical force to the fabric rods (4), fabric rods (4) fixed to the frame rods (3);

- cloth bars (4) to which the shafts (5) are to be fixed;

- shafts (5) for fastening and winding cloth (6);

- a cloth (2) on which the patient to be transformed is laid;

- Actuators consisting of electric motors, reducers, other moving, transforming devices;

- Control system to control actuators to properly convert patient ·

For the sake of clarity of description of the present invention, it will be appreciated that the frame (2) and the entire structure of the patient bed unit (1) are symmetrical to a plane (symmetry plane) parallel to the elongated end members of the frame (2). two elongated elements of the frame (2), and the plane of symmetry being in the middle of said connecting element, the description will show only one side of the construction of the frame (2) and the whole device (1), assuming that the other symmetrical side is identical. Said symmetry plane divides the whole device (1) into two identical parts. The frame (2) of the hospital bed turning device (1) resembles a U-shaped geometric pattern, ie: the frame (2) consists of at least three interconnected elongated elements, the middle connecting the other two elongated, lateral) to the end of the bed body part. The other two elongated, lateral elements of the frame (2) are placed along the patient's body, at the sides of the bed. The transverse cross-section of the elongated elements forming the frame (2) can be adapted for attaching the frame (2) to the bed. The frame (2) must be stable and fixed. In one embodiment of the invention, the frame (2) can be fixed to the bed structure by means of device attachments for attachment to the bed structure (not shown in the drawings). In another embodiment, the frame (2) may have stable contact with the floor, i.e., resting on the floor with supports (not shown in the drawings) or otherwise. It is essential to ensure that the frame (2) is able to hold the entire structure of the device (1), which pushes the patient in bed, and the loads acting on it. In another embodiment, the frame (2) may be made of a solid material. In yet another embodiment, the frame (2) can be flexed at certain locations so that the entire device (1) can be folded for convenient transport. In another embodiment, the frame (2) can be disassembled into separate parts. The requirement for the frame material and structure is physical strength, the ability to withstand the loads caused by the patient being tipped sideways.

The frame rod (3) is pivotally mounted to the U-shaped free end of the frame (2).

In another embodiment, the frame bar (3) may be attached to the frame (2) at a bending point of a U-shaped elongated member having a free end, i.e., a connection with the middle member of the frame (2). Frame Rod (3) - Elongated, slender structural member. The cross-sectional shape of the frame bar (3) may be a circular, rectangular, or other shape. The frame rod (3) is fixed at one end to the frame (2) by a hinge. The frame (2) is hinged to the frame bar (3) and can be bent through the hinge. The present invention employs a hinge that can hinge around a single axis, in the present invention perpendicular to an elongated lateral member of the frame (2). The force required to flex between the frame (2) and the frame bar (3) is supplied by an electric motor with a reduction gear. The worm reducer can be used in the present invention because of the high ratio of rotational motion transmission required, and worm gearboxes can lock in a locked position of the frame (2) and the frame bar (3) without energy consumption.

At the other end of the frame bar (3) than the attached frame (2), a cloth bar (4) is fixed at one end. Weave bar (4) - An elongated, lean structural member, may have a shape similar to that of a frame bar (3). The other end of the cloth bar (4) is left loose and no extension element of the device (1) is attached to it. The cloth bar (4) is attached to the frame bar (3) identically to the frame bar (3) attached to the frame (2). A hinge is used to connect the frame bar (3) and the cloth bar (4), the movement being executed by an electric motor with a gear unit.

A shaft (5) is attached to the cloth bar (4), on which the cloth (6) is wound. The shape of the shaft (5) resembles an oblong, slender cylinder. In another embodiment, the shaft (5) may be in the form of a hollow tube and the cloth bar (4) is housed and secured inside the shaft (5), such that the shaft (5) surrounds the cloth bar (4), i.e.: (5) The axis around which the shaft (5) rotates. The shaft (5) is fixedly secured to the fabric rod (4) by means of fasteners which have bearings that allow the shaft (5) to rotate about its longitudinal axis, the shaft (5) being connected to the drive mechanism. In this embodiment, the actuator comprises an electric motor, a reducer and other actuators which cause the shaft (5) to rotate about its longitudinal axis. The actuators must allow the shaft (5) to rotate about its longitudinal axis in both directions. The rotation of the shaft (5) must be fully controlled and there must be no slack. The actuator must ensure a secure locking position of the swivel shaft (5).

Frame (2), frame bar (3) and cloth bar (4) with spindle (5) viewed from the side of the device (1) (ie: if the device (1) is in working position, at the end of the bed viewed from the side of the bed) , may resemble a Z shape, where the angles between the elongated elements that make up the shape may vary.

The present invention uses a rectangular cloth (6). The cloth (6) is wound on both shafts (5) and extends between the shafts (5) on the bed surface. The fabric (6) shall be of sufficient physical strength to withstand the stresses to which the patient is subject. The patient is lying on the bed linen (6). The fastening of the cloth (6) to the shaft (5) must be implemented in such a way that the cloth can be easily attached and removed from the shaft (5). The cloth (6) must be firmly secured to the shaft (5) without being able to pivot, slip or otherwise change.

The device (1) is fixedly fixed in its working position with its frame (2) (according to different embodiments it can be mounted on the bed, on the floor or otherwise). The elongate connecting member of the device (1) frame (2) is usually located at the end of the bed on which the patient's head is resting; the elongated side members of the frame (2) are fitted to the sides of the bed. The frame rods (3) can rotate about the axis of their attachment to the frame (2), thereby changing their inclination angle with respect to the frame (2).

The device (1) transmits the translation of the patient through the cloth (6), i.e., by properly controlling the tension of the cloth (6) at different points thereof, it is possible to render the patient appropriately, conveniently for the patient. The tension of the web (6) can be adjusted at different points by winding, rolling away from the shafts (5) and also by varying amplitude by raising the ends of the frame bar (3) and the web bar (4).

In one embodiment, when the frame bars (3) (or one of them) are attached to the frame (2) near the folding points of the frame (2) by lifting and lowering the ends of the frame bar (3), movement of the pelvis of the patient body can be controlled. The body part at the pelvis can be more or less turned in different directions. By lifting one end of the frame bar (3), the patient's body part at the pelvis will be turned toward the other frame bar (3). If one end of the frame bar (3) is raised high enough, the patient's body can be slightly tilted by twisting and wrapping the cloth (6). Lifting only the end of the cloth bar (4) lifts the patient's upper shoulder to allow partial or complete planting of the patient. By partially positioning the patient, controlling the lifting amplitude of the frame bar (3) and / or unwrapping the cloth (6), it is possible to turn the patient's body at the pelvis.

If the frame bar (3) is attached to the frame (2) at the free end of the elongated element of the frame (2), then the patient's movement (planting, turning) is implemented by moving the corresponding bar, ie: final lowering and / or lifting; lifting and / or lowering the free end of the cloth bar (4) moves the patient's body part along the pelvis. The wrapping (6) of the cloth (6) on or off the shaft (6) helps to properly physiologically transform the patient. Proper tensioning of the web (6) prevents the formation of wrinkles on the web (6), which can increase local pressure on the patient's body, which increases the likelihood of herniation.

The partially planted patient can be slightly turned by winding the cloth (6) from one shaft (5) to another and / or by varying the amplitude by raising and t or lowering the ends of the frame rods (3) not attached to the frame (2).

The design of the device (1) allows the patient to be tilted with respect to the center of gravity of the body and the maximum amplitude of movement of the center of gravity is required for the most convenient translation of the patient, i.e. the device (1) enables different body positions and translations. In order to convert patients of different body shapes it is necessary that parts of the cloth (6) that are in contact with different parts of the patient have different amplitudes, for example: in order to properly accommodate a larger hip, it is necessary to move the cloth (6) stretched) most. The structural members of the device (1) on one side of the bed, which can move independently of the other side members of the bed, can implement pulling of cloth of different strength and amplitude at the patient's shoulders and at the patient's pelvis.

The mechanical design of the device (1) is powered by the aforementioned electric motors with reduction gear and other torque transmission systems. Total device (1) contains:

- two actuators for lifting the frame bars (3), i.e. for changing the size of the junction / connection angle of the frame (2) and the frame bar (3);

- two actuators for lifting the fabric rods (4), i.e. for changing the angle of joint / connection of the frame rod (3) and the fabric rod (4);

- and two actuators for turning the shafts (5).

All the aforementioned actuators are combined into a single control unit which controls and controls the position of the whole unit (1). The said control device may be electrical switches for switching the supply of power to the actuators; may be an electronic device which controls the actuators of the device according to a predetermined order, instructions, algorithm; the control unit may be a highly integrated electronic device (microcomputer, computer, smart wearable device) provided with the necessary software to perform the functions of the actuator controls listed above, which may further adjust the patient tilt parameters depending on the patient characteristics. Electronic devices monitoring the load (1) of the whole device (1), the speed of movement and other operating parameters of the device (1), which can determine the most appropriate bed resting mode and characteristics, are required to adjust the patient's tilting parameters.

The device (1) may include a device for generating and emitting an audible and / or visual signal which, at regular intervals, informs the person supervising the patient of the need to change the position of the patient. The person supervising the patient connects the device (1), setting the operating mode of the device (1), which at that time is most suitable for changing the patient's position. As long as the device changes the position of the patient, the person supervising the patient must monitor the operation of the device and the position of the patient. When the device (1) sufficiently replaces the patient's assistant, the person supervising the patient, if necessary, adjusts the position of the patient's body or individual parts by switching off the device (1). When the shafts (5) are parallel to the bed plane and the longitudinal axis of the bed, the device (1) rotates the shafts (5), i.e. rolling the cloth (6) off one shaft (5) and wrapping it on another shaft (5) can change the position and / or position of the patient in the bed, i.e. to move the patient from one place to another in the bed.

In another embodiment, the frame rods (3), together with the cloth rods (4), can vary the position and / or position of the bed relative to the bed to form a slope of the cloth (6) that causes the patient to towards the downward sloping slope.

In another embodiment, the operation of the device (1) may be implemented by combining the two modes of operation described above, i.e. By changing the position of the frame rods (3) and the cloth rods (4) and by rolling and wrapping the cloth (6) away from the shafts (5), the patient position and / or bed position can be changed both parallel and perpendicular to the longitudinal axis of the bed.
