Description

The group of inventions relates to components, structural elements and auxiliary devices of hospital beds and can be used to care for bedridden patients and persons with disabilities, both in hospitals and medical facilities.

Care for bedridden patients and persons with disabilities is associated for staff with heavy physical exertion.

To reduce such loads allow medical lifts, which, as a rule, have certain disadvantages.

For example, it is known a lifting device US 6047418 A, 04/11/2000, containing a vertical L-shaped rack with a drive mounted on a movable platform and connected by a rod with a removable suspension frame.

The disadvantages of the device US 6047418 should include a decrease in its stability that occurs when you turn the L-shaped rack and its location across the movable platform. Limiting the rotation of such a rack makes it difficult to service the patient and significantly affects the performance of the lift, which cannot be used to shift the patient to a bed that is parallel to the movable platform.

A device for lifting and transporting patients, known from the description to the copyright certificate SU 946541 A, 07/30/1982, also contains a vertical L-shaped rack on a movable platform and has the same disadvantages.

Closer to our lifts is the apparatus US 5499408 A, 03/19/1996, which serves to move the disabled and contains vertical support racks connected by crossbars, a frame with a removable suspension, a drive mounted on a movable carriage placed on horizontal guides mounted at the upper ends of the vertical support struts, and traction associated with the movable carriage and connected by hinges to the frame.

The apparatus US 5499408, which includes four supporting vertical racks, does not have the drawbacks of devices with L-shaped racks, but its significant drawback is its complex design, which requires simultaneous transmission of drive forces to different traction to lift the patient.

A common drawback for all of the above structures is the lack of funds in them that ensure that the removable suspension of the lift is brought under seriously ill or disabled.

Bringing the removable suspension of the elevator under the patient is one of the most difficult and difficult stages in its maintenance and is performed, as a rule, by manually lifting the patient's body by the maintenance personnel.

The task to which the present group of inventions is directed is to create options for a structurally simple lift for seriously ill patients and people with disabilities and a device specially designed for it, which will make servicing patients more simple and convenient.

The technical result of the invention is to improve patient care without significant physical effort on the part of staff and, as a result, a positive impact on the health of seriously ill and disabled people.

The essence of the first embodiment of the invention is expressed in the aggregate of essential features, in which a lift for seriously ill and disabled people, comprising vertical support racks connected by crossbars, a frame with a removable suspension, a drive mounted on a movable carriage placed on horizontal rails mounted at the upper ends of the vertical support racks , and traction associated with the movable carriage and connected by hinges to the frame, in contrast to the closest analogue additionally contains a lever mounted with possibly rotation around an axis mounted on a movable carriage, while the rods are connected to the frame via axial joints, the short arm of the lever is connected to the drive, and the long arm of the lever is connected to the frame by a movable connection and is 1.5-3 times longer than the length of the short arm, the removable suspension has a bracket for a device for installing a removable suspension for seriously ill or disabled persons, described below.

The above set of essential features of the first invention is sufficient to achieve the technical result of the proposed group of inventions in all cases to which the requested amount of legal protection applies.

In special cases of its implementation or use, the first version of the lift may contain:

two vertical support racks made for fastening to the bed;

vertical support racks made for fixing the bath, or vertical support racks equipped with removable horizontal jumpers and soft material that does not pass water and is placed between the racks and removable horizontal jumpers in the form of a bath;

a drive that is electromechanical and has the ability to transmit movements for therapeutic exercises;

removable suspension in the form of belts;

a bracket for a device for installing a removable suspension for seriously ill and disabled people, made in the form of an isosceles trapezoid, the largest base of which is connected to the belt, and the small one has a bend in the form of a retainer located in the plane of the isosceles trapezoid and oriented towards the largest base;

remote control.

The essence of the second variant of the invention is expressed in the aggregate of essential features, in which the lift for seriously ill and disabled people, containing a frame with a removable suspension, a drive mounted on a movable carriage placed on horizontal guides, and traction associated with a movable carriage and connected by hinges to the frame, is different from the closest analogue in that it further comprises a lever mounted rotatably about an axis fixed to the movable carriage, wherein horizontal guides are connected with crossbars made for mounting on the ceiling or for mounting on the wall, the rods are connected to the frame via axial joints, the short arm of the lever is connected to the drive, and the long arm of the lever is connected to the frame by a movable connection and is 1.5-3 times longer than the short shoulder, and the removable suspension has a bracket for the device for the establishment of a removable suspension for seriously ill or disabled people, described below.

The above set of essential features of the second invention is sufficient to achieve the technical result of the proposed group of inventions in all cases to which the requested amount of legal protection applies.

In special cases of its implementation or use, the second version of the lift may contain:

a drive that is electromechanical and has the ability to transmit movements for therapeutic exercises;

removable suspension in the form of belts;

an arm for a device for installing a removable suspension for seriously ill or disabled people, made in the form of an isosceles trapezoid, the largest base of which is connected to the belt, and the small one has a bend in the form of a retainer located in the plane of the isosceles trapezoid and oriented to the largest base;

remote control.

The essence of the third invention is expressed in the aggregate of essential features, in which the device for bringing the removable suspension of the lift under a seriously ill or disabled person is made in the form of a wire frame having the shape of an isosceles triangle with a base in the form of a handle and with two elongated sides converging at an acute angle to an arcuate peak, while the elongated sides have a plane bend located at a distance from the top of the arc, equal to 1 to 8 arrows of deflection of the vertex arc.

The above set of essential features of the third invention is sufficient to achieve the technical result of the proposed group of inventions in all cases to which the requested amount of legal protection applies.

In special cases of its implementation or use, the device for the establishment of a removable suspension for the lift for seriously ill and disabled people may contain:

elongated sides that are oriented toward the arcuate apex at an angle of 8 to 12 ° and have a plane bend made at an angle of 8 to 16 °;

lengths from 450 to 1000 mm.

The causal relationship of the above features with the technical result of the invention is manifested in the fact that the lever, mounted with the possibility of rotation around the axis, can significantly simplify the design of the elevator and lift the patient with a force applied at one point, i.e. to make the patient’s recovery optimal. The ratio of the shoulders of the lever, in which the short shoulder is connected with the drive, and the long shoulder of the lever is connected with the frame and is 1.5-3 times longer than the length of the short shoulder, allows you to make the patient lift smoother and, accordingly, safe, which also helps to connect the rods with frame through axial joints. For example, with a long arm of a lever of 800 mm and a short arm of 300 mm, the movement of the patient did not significantly affect his condition, while when the ratio was changed, the patients experienced discomfort. Fastening the lever to the movable carriage allows the patient to move outside the bed. The presence of a bracket in a removable suspension bracket for a device for bringing the suspension under seriously ill or disabled allows you not to apply physical effort when placing the patient on the suspension.

The implementation of the device for bringing the suspension for seriously ill or disabled people in the form of a wire frame having the shape of an isosceles triangle with a base in the form of a handle and with two elongated sides converging at an acute angle to the arcuate apex allows it to easily pass under the patient’s body without causing him undue concern .

A plane bend on the elongated sides, located at a distance from the top of the arc, equal to 1 to 8 arrows deflection of the arc of the top, provides easy traction of the bracket and devices for bringing the suspension under seriously ill or disabled. For example, when the bend is located on the plane at a distance equal to one arrow of the deflection of the vertex arc, the bracket and suspension are engaged without negative impact on the patient’s body, however, when this distance is reduced, patients had unpleasant sensations.

Vertical support posts connected by crossbars and horizontal guides connected to crossbars made for mounting to the ceiling or for mounting to the wall ensure the stability of the lift, and also make it possible to use the embodiment that is most suitable for specific care conditions and the room.

The invention is illustrated by drawings, where figure 1 shows a side view of a lift for seriously ill and disabled people, made in the embodiment for installation along the bed with support on the floor; figure 2 is an end view of the elevator shown in figure 1; figure 3 is a view of the bracket for the device for the establishment of a removable suspension for critically ill and disabled people, figure 4 is a front view of the device for the installation of a removable suspension for critically ill and disabled people and figure 5 is a side view of the device for creating a removable suspension for critically ill and disabled, depicted in figure 4.

In an embodiment, for installation with a support on the floor, the elevator for seriously ill and disabled people contains vertical support racks 1 connected by crossbars 2, a frame 3 with a removable suspension, a drive 4 mounted on a movable carriage 5, mounted on horizontal guides 6, mounted at the upper ends of the vertical support racks 1, rods 7, connected with the movable carriage 5 and connected by axial hinges 8 with the frame 3, and a lever 9 mounted for rotation around an axis 10 mounted on the movable carriage 5. Short lever arm 9 connected to the drive 4. The long arm of the lever 9 is connected to the frame 3 by a movable connection and is 1.5-3 times longer than the length of the short arm. The removable suspension has a bracket 11 for a device for installing a removable suspension for seriously ill or disabled people.

The bracket 11 is made in the form of an isosceles trapezoid. The largest base 13 of the isosceles trapezoid is connected to the belt 14, and the small base 15 has a bend in the form of a latch 16. The latch 16 is located in the plane of the isosceles trapezoid and is oriented towards the largest base 13.

The device for bringing the removable suspension of the lift under a seriously ill or disabled person is made in the form of a wire frame having the shape of an isosceles triangle with a base in the form of a handle 17 and with two elongated sides 18 and 19. The sides 18 and 19 converge at an acute angle to the arcuate peak 20. The elongated sides 18 and 19 have a bend 21 in a plane located at a distance from the vertex 20 of the arc, equal to 1 to 8 arrows of deflection of the arc of the vertex 20.

In the process of operation of the elevator, the device for bringing the removable suspension of the elevator under a seriously ill or disabled person, made in the form of a wire frame, is brought under the patient, holding it by the base in the form of a handle 17. The arcuate top 20 of the wire frame, which connects the elongated sides 18 and 19, converging to it at an acute angle, easily passes between the patient’s body and the linen on the mattress, without causing him any inconvenience. A bend 21 of the elongated sides 18 and 19, made on a plane, will allow you to easily connect the device and the isosceles trapezoid of the bracket 11. The fixture and the bracket 11 are engaged by placing the latch 16 between the two elongated sides 18 and 19 and the arcuate peak 20 and allows you to bring the belt 14 under the patient , and then the entire suspension, which is fixed to the frame 3.

Drive 4 is started and by turning the lever 9 on the axis the frame 3 is raised with the patient placed in a removable suspension and the drive 4 is stopped. Since the long arm of the lever 9 is connected with the frame 3 by a movable connection, the angle between the frame and the lever changes while maintaining the position of the patient, which was originally set when installing and adjusting the suspension.

After performing the necessary actions (changing the sheet, wiping, putting up the vessel, changing the diaper, etc.), drive 4 is started again and the patient is lowered onto the bed.

If, after raising the patient, further actions are not carried out on the bed, the attendant, holding the drive 4, moves the movable carriage 5 along the horizontal guides 6 fixed at the upper ends of the vertical support posts 1 and lowers the patient onto a gurney, dry closet, etc.

When performing drive 4 electromechanical raising and lowering of the patient is carried out using an electric motor. The movement of the movable carriage 5 along the guides 6 (rails) can be made both serving and using an electric motor. Some patients can move themselves using the remote control from the bed to the dry closet, wheelchair, etc.
