Abstract

In order to enable the position of a patient in a bed to be changed easily, without excessive physical exertion, to avoid decubitus ulcers (bedsores), the invention calls for shafts (4a and 4b) which can be lifted upwards to be disposed one along each side of the bed. Rotation of the shafts (4a and 4b) winds a sheet (7) spread over the mattress (3) round them or unwinds the sheet. The patient is moved into the required position by coordinated rotation of the shafts (4a and 4b) and the shaft-lifting levers (5a, 6a; 5b, 6b) or by relocating another special device.

Description

Aid device for bed

The invention relates to an auxiliary device for a bed, in particular a hospital bed, which consists of shafts arranged laterally to the two long sides of the bed, the shafts being rotatable about their longitudinal axis in order to wind a sheet from one shaft to the other. The beds, which essentially consist of a bed frame, a resilient underlay (mattress) and an adjustable head section, have been adapted to the needs of patients and nursing staff in a variety of ways. The lying surfaces are adjustable in height. The head and foot sections can be varied and the bed frame can be moved.

However, there are special problems in patients who themselves can hardly or not move at all. Lying on the same area of a part of the body for a long time creates slightly sore spots on the surface of the body, which are very dangerous to health, difficult to heal and painful. This leads to the dreaded pressure points (lat. Pressure ulcers). Such a clinical picture is difficult and costly to cure and leads to death in the advanced stage. The nursing staff is therefore required to regularly move such immobile patients to a different position so that the parts of the body that are subjected to lying down are constantly changed. This is physically very difficult work with possible long-term damage to the spine and the associated loss of the caregiver, and there is also not always someone, especially at night, available to change the position.

Various mechanical auxiliary devices for changing the position of persons with reduced mobility have already become known to relieve the care personnel. In SU-PS 1 776 400, belts are provided on fixed or height-adjustable supports, which reach under the patient and lift them from the bed support by adjusting the height of the supports or turning them into a side position by hanging them on one of the supports. The disadvantage is that the whole bed is a special construction and the straps are not usable as a permanent rest. DE-OS 35 90 309 provides a sheet, which is arranged between two shafts, two opposite sides of the sheet being wound around one shaft each. In order to turn a person lying on the sheet, the sheet is wound from one shaft to the other, and the shafts and hinges on the side are difficult for the operating personnel. By If the hinges to which the shafts are attached are folded down, the shafts should be lowered so that a person can get out of bed better. This is a cumbersome construction that is unlikely to be practically accepted due to the difficult handling. In addition, an adapted bed construction is necessary for the attachment.

The invention has for its object to find a receiving device for the sheet to be wound up, which does not hinder the nursing staff, is easy to handle, can bring about any desired changes in the patient's position and can be easily attached to any conventional bed.

To achieve this object, the features specified in the patent claim are proposed.

The holding devices, which can be attached to the head and foot ends, for receiving the waves, at different heights, can on the one hand bring the patient into any desired height and oblique position, and can also rotate into another desired position about his body axis. In the lower starting position, the waves and levers are in no way disturbing for the nursing staff.

In the drawing, the invention is illustrated using exemplary embodiments. Show it:

The mattress -3- is located between the head end -1- and the foot end -2- of the bed. The shaft -4a- is arranged parallel to the right edge of the bed. Both at the head end and at the foot end in the levers -5a- and -5b- is rotatably mounted.

REPLACEMENT LEAF The levers -5a- and -5b- can be swiveled upwards towards the center of the bed, as can be seen in the positions indicated, whereby the shaft -4a- is lifted over the mattress -3- towards the center of the bed. A corresponding counter-rotating device is also attached to the left side of the bed.

In FIG. 1, only the levers -6a and -6b are indicated in different positions.

2, 3, 4 and 5 show the mode of operation of the auxiliary device. For the sake of clarity, only the half of the bed towards the head end -1- is shown. 2, the levers -5a- and -6a- are pivoted completely outwards and downwards in the starting position. Over the mattress -3- is the cloth-like pad -7- (sheet), which is attached to the two side shafts -4a- and 4b- so that the pad -7 turns when the shafts -4a- and -4b- Depending on the direction of shaft rotation, the cloth-like support -7- moves in this way to the right or left edge of the bed. The possibility of rotation of the shafts -4a- and -4b- is indicated by the arrow arcs P and P1. In addition, the shafts -4a- and -4b- can be moved using the levers -5a- and -6a- (as well as the lever (not shown at the foot end)) according to the arrows P2. Fig. 3 shows a position with levers -5a- and -6a- slightly raised and lateral shafts -4a- and -4b- which have been raised up to that point. This is the safety position, because the patient cannot roll out of bed in this way. The raised waves -4a- and -4b- together with the support -7- form a barrier. Fig. 4 shows the patient after the position has changed from back to side. The levers -5a- and -6a have been pivoted even further upwards and the support -7- has lifted off the mattress -3-. Depending on the direction of rotation of the shafts -4a - and -4b- the patient can be rolled onto his left or right side. His back areas are relieved of lying pressure, the stressed areas can be supplied with blood again, which prevents the development of sores (pressure ulcers). The device can be operated both by hand and by motor. In manual operation, the shafts -4a- and -4b- are rotated using modified hand cranks, all of which is done without physical effort for the nursing staff. It is also possible to carry out a regular, automatic change of the patient's position by equipping it with a program control. The times and the extent of the lever movements can be adapted to all requirements. 5 shows the patient in a lateral position, the position stabilization being achieved by further raising the waves to the left or right depending on the position.

REPLACEMENT LEAF In addition to the one described above, the special device can also consist of special guides and of electrical “hydraulic or pneumatic cylinders.

The constructive structure of the individual components of the auxiliary device is of crucial importance for practical testing. 6a and 6b show the structure of the assembly unit to be attached to the foot end or head end of a bed with the levers 5a and 6a, which are each latched and pivoted in a guide chamber 8a or 9a. The levers 5a and 6a can be snapped into a locking plate 10a and 11a at fixed swivel heights. The two guide chambers 8a and 9a are connected to one another by means of the interchangeable intermediate plate 12. If, for example, the auxiliary device is to be mounted from a narrower bed to a wider bed, then the intermediate link which is decisive for the narrower bed only has to be replaced by a wider intermediate link. Because the levers 5a and 6a are each mounted in a guide chamber 8a and 9a, all moving parts that are prone to accidents are protected at the critical points. 7 shows the rotatably mounted shafts 4a and 4b with the levers 5a and 5b on a larger scale. In order to be able to compensate for different lever movements and also transverse displacements of the head part and foot part, the shaft consists of telescopically displaceable sections. The rotary sheet is received by the tubular middle part 13, into which one of the end parts 14 rotatably mounted on the levers is inserted, while the driven counterpart 15 is coupled in a rotationally secure manner to the middle part 13 by means of the pipe clip connector 16 extended by the middle part 13 and driven counterpart 15. When the counterpart 15 is rotated by means of a crank attached to the crank pin 17, the central part 13 is rotated about the longitudinal axis to wind up or unwind the sheet. If the auxiliary device is motor-driven by a motor M placed on the end part 14, then only the pipe clip 16 has to be implemented on the end part 14. Now the middle part is rotated via the end part 14, whereby it rotates freely around the telescopic part 18 'of the counterpart 15. End part 14 and counterpart 15 are provided with a universal joint 2o or 2o 'between telescopic part 18 or 18' and the lever bearing 19 or 19 '. If the shaft is lifted on one side, excessive kink loading is prevented, and problem-free transverse displacement of the headboard and footboard of the bed is made possible. Telescopic guide and universal joint ensure the compensation of the differences in length between the bearing points and the bridging of the changing angles between end piece 14 or counterpart 15 and middle part!

Transporting a patient from a bed to a stretcher or treatment table, e.g. B an x-ray table is particularly difficult for caregivers. The auxiliary device according to the invention brings significant relief here. The levers of a shaft can be pulled apart for extension so that a 'ramp' protrudes above the edge of the bed, which can be brought to and at the level of the transfer table. Now the patient can be easily pushed out of bed onto the X-ray table or the like. 8 shows such a possibility of use.

The most varied functions in manual operation of the auxiliary device are to be listed again in a table in the most important functions for better understanding.

A Open the sheet with an empty bed.

Unfold 1 sheet over the bed.

2 Lay across the bed with the long side and down with the fleece band.

3 Position the turn sheet marking in the longitudinal axis and center of the bed.

Swivel 4 tubular shafts (right and left) into an upper position and snap them into place.

Press the velcro strips of the turn sheet straight and firmly onto the Velcro strips of the tube shafts, if the head is to be supported, start at the side of the head, otherwise as required.

5 Turn both tube shafts one after the other using the winches, with the taut sheet tightly, until about 5-6 turns have been wound up. The right tube shaft is turned clockwise and the left tube is turned. The two turn sheet markings remain in the middle of the bed. It is turned until the turn sheet is nice and smooth and tight.

6 Loosen the turn sheet with the two winches on both sides until it touches the mattress.

7 Swing the two tube shafts into the lowest position, smooth the sheet, both

Slightly tighten the tube shafts and the bed is ready.

B Open the turn sheet with the patient in bed.

Unfold 1 turn sheet and have it ready to pass under the patient.

2 Lift the patient up with the bed sheet and guide the swivel sheet through it and align it or push it together next to the patient and roll it over the swivel sheet as with the bed sheet.

3 Lower the patient, swivel the shafts (right and left) into an upper position and engage.

Press the fleece tapes of the turn sheet straight and firmly onto the Velcro strips of the tubular shafts.

4 Depending on the size of the patient, latch the side tubular bars (left and right) into the highest or second-highest catch.

If the head is to be supported, start with the turn sheet attachment closer to the head side, otherwise attach as required.

5 Use the winches to turn both tube shafts until the turn sheet is slightly tensioned.

Here, the right tube shaft is turned clockwise and the left counterclockwise.

tt The two turn sheet markings remain in the middle of the bed. 6 Swivel the two tubular shafts down, tighten slightly and the bed is ready.

C patient turning.

1 Turn counterclockwise and clockwise.

Depending on the size of the patient, latch the lateral tube shafts (left and right) into the highest or second-highest catch. Depending on requirements, the turn sheet should be loosened slightly before swinging up.

Slightly raise the patient by turning the two cranks in opposite directions.

Turning the two cranks clockwise turns the patient against the

Clockwise, i.e. in opposite directions. If you change the direction of rotation of the two cranks, the patient turns clockwise.

This is from the back to the prone and any position you want

Liner possible.

It is no longer possible to turn beyond the prone position, otherwise the turn sheet will overturn and unwind from the shaft.

2 From the prone position, the patient must be turned back in the opposite direction of rotation. This then goes back to the prone position.

The patient can therefore not be rotated continuously in one direction of rotation, but must be rotated back and forth or left and right in the cycle.

D special functions.

1 Stabilize the side layers.

Snap the tube shafts in the patient's back into one of the three locking positions so that the patient is optimally supported.

Relax the turn sheet slightly.

If necessary, cushion them with pillows.

2 Support the prone position.

Raise the patient by turning the two crank handles in opposite directions.

Place the pillow under the chest and chin so that the patient can breathe freely.

Drain patient.

For unconscious patients, these with exposed breathing openings in the slightly tense

Leave the turn sheets.

REPLACEMENT LEAF 3 Safety against falling out.

Snap the two tubular shafts into the first position.

4 Privacy protection against unwanted looks.

Snap both tube shafts into one of the two upper positions with the rotary sheet relaxed.

In hospital and nursing home operations, it is advantageous to perform the functions not by hand, but by means of a motor drive. When the motor is switched on using a foot control, the caregiver has the option of using his free hands to secure any supply hoses or the like when moving the patient.
