description

The invention relates to a device for rotating a human body, with which the position of a a person lying in bed can be changed in a simple manner, according to the invention by means of a Device based on the basic principle of the rotary motion of rigid bodies. Examples of one on a bed Lying person is a person who is being examined in a hospital, a person who is a medical one A physically disabled person in an asylum, a bedridden elderly, or subject to treatment a person who is bedridden at home for a long time.

During radiation treatment in a hospital, it is often necessary to adjust the position of the body examining person on a bed is often changed because the rays come from different directions have to. Especially with the X-ray examination of the digestive tract it is essential that the to be examined Person lies on a bed and changes their body position to the right or left repeatedly to get a Introduce or apply contrast media to the affected part and the optimal fluoroscopic direction and to choose fluoroscopic timing. In the conventional In practice, the person to be examined makes these changes himself in accordance with the instructions of the operator the end. In most cases, however, the person being examined does not know how to position themselves the hard and narrow X-ray table is supposed to change, resulting in errors, discomfort, time delays, tensions and the like arise. This can provide an accurate x-ray fluoroscopy with changing conditions for the Prevent patients. Especially in the case of a through

O ₅ illness seriously debilitated patient, a physically disabled person, an elderly person or a child, the required change of position is difficult, even with the help of a helper, and thus the

Investigation is often impossible.

One exclusively for examining the digestive tract provided device for turning a human Body, such as a gyro-type fluoroscopic table, is known. However, such a facility a complicated mechanism, and requires considerable expenditure for an exclusive Use. The disadvantage here is that the body rotation angle is limited and the person to be examined by means of a Tape tied to a plate and the body must be rotated in the suspended state. As a result, it is difficult to use such a device on a weakened person, an elderly person or a child.

In addition, due to the high cost, such a facility can be used even in large or exclusive hospitals Examination and treatment centers are hardly set up.

The object of the invention is therefore to create a device for rotating a human body with which the position of a patient lying on a medical bed by means of a simple and inexpensive Construction can be changed quickly and safely.

The invention thus relates to a device for rotating a human body, in which rotating shafts are arranged parallel to one another and are rotatable about their own axes and around which a body wrap is around which is movable in a concave curved shape so that a body lying thereon is rotated will.

Fig. 1 illustrates a device 2 for rotating a human body, which is for use on a fluoroscopic table 1 is installed, which is used to rotate and lift a body for an X-ray examination of the digestive system that is straightforward. The rotating device 2 comprises a floor frame 3 which is approximately the same size as having an end face of the fluoroscopic table 1, and end plates 4, which are upright on both longitudinal Ends of the table. Rotating rods or rotating shafts 5 are rotatably fitted between bearings 6 which are shown in the end plates 4 are arranged. Four rotating shafts 5,

namely upper rotating shafts 5a on both transverse sides or opposite one another Sides on the top of the end plates 4 and lower rotating shafts 5b on both opposite sides on the underside are arranged parallel to each other. Each rotating shaft 5 is made of hard plastic pipe made of polyvinyl chloride with a length of about 100-200 cm and an outer diameter of 30-150 mm or made of a plastic tube made of a carbon fiber mixture or a rigid pipe material such as iron or steel with a diameter of 20-30 mm made. Two rotating shafts 5 on the outer sides are fitted in bearings 6 which are located on both transverse surfaces of the Fluoroskoptisch.es or fluoroscopic tables 1 are installed. A sheet or cloth 12 for enclosing a body that is about 100-200 cm wide

Ig or mainly 180 cm for adults is on both end parts connected to form rings and the rotating shafts 5 are arranged within the rings and the Body wrapping cloth 12 is placed around the outside of the four rotating shafts 5. Each ring has such a length

2Q on that the body wrap 12 if a human Body lies between the upper rotating shafts 5a, between the upper rotating shafts 5a in the form of a concave Surface is curved and is subjected to tension between the other rotating shafts 5. The distance between the upper rotary shaft 5a is about 40-90 cm, that is, it is sufficient to enclose a human body between them. The shaft ends of the rotating shafts 5 protrude from the face plate 4 and are provided with a rotary drive device 7 and a transmission gear 8 connected. the

gQ rotary drive device 7 is a motor with an output power of about 100 watts, while the transmission 8 is a combination of a sprocket 10 and a Chain 9 or the like includes. However, other devices such as a pulley, a belt, a

gc rack device, an anchor device or a Braking device be provided. The rotary drive device 7 is surrounded by a housing 11. The rotating shaft 5 is provided with an engaging part 13 for engaging

-δι provided with the body wrap 12. The intervention steep 13 can consist of a combination of a gear, a velvet cloth fastener, a chain, a belt with teeth and openings and the like. In the illustrated embodiment, the engaging part 13 is made of a polyvinyl chloride resin sheet with a Thickness of 1-3 mm built up and partially or fully attached to a section where the lower rotating shaft 5a the Body wrapping cloth 12 touched. The engaging means of the body wrapping sheet 12 may well be made of polyvinyl chloride resin sheet, Rubber sheet or rubber sheet, or a reinforced one composed of these materials Slide. In the embodiment according to Figure 1, transparent polyvinyl chloride film with a thickness of 1-3 mm applied. This film is partially or almost entirely placed around the outer circumference of the rotating shaft 5 and is used as the body wrap sheet 12. Because with this training, the surface of the polyvinyl chloride film is sufficient Has adhesion, the coefficient of friction becomes in the contact area between the body wrapping sheet 12 and the rotating shaft 5 becomes large and becomes adhesive in the direction of contact Reached torque that is sufficient to move the wrapper 12 around the body. As a result, it is not necessary to provide a separate engagement device. In this way, the facility is simplified and the safety for a medical instrument becomes great. Since such a film material or cloth material furthermore has a suitable shape-retaining property, it depends Wrap wrap will not pass when device is upright and will not warp when rotated. In addition, excessive feeding of the body enclosing sheet 12 due to excessive rotation becomes impossible the rotating shaft 5 avoided.

The body wrap sheet 12 is made of a material which is thick and easy to touch and easily washed and does not constitute an obstacle to x-ray fluoroscopy, e.g. polyvinyl chloride,

Rubber, gum, cloth, artificial leather or other artificial cloth or a reinforced one composed thereof Material. A transparent cloth is preferably used. The body wrap 12 is with a height of about 10-50 cm above the fluoroscopic table 1 held by means of the two upper rotating shafts 5a. During the examination, if the fluoroscopic table 1 is in an upright position, then a person to be examined is standing between the upper rotating shafts 5a. In this arrangement, the bearing 6 is arranged in the upper side of the face plate 4 so that that it can be moved freely along the surface of the face plate 4. The position of the bearing 6 becomes varies depending on the body size of the person to be examined and the upper rotating shaft 5a becomes moved so that the body enclosing width of the body enclosing cloth 12 is set. By increasing the distance between the two upper rotating shafts 5a, avoided that hair or clothing of the person to be examined jammed in the rotation of the rotary shaft will. The body wrap 12 can be made of transparent film material or sheet material, see above that the person surrounded by the body wrapping sheet 12 can be easily observed. Along the central longitudinal axis For example, a table contacting rope or belt may be provided to secure the body wrap 12 thereto prevent it from wrinkling or drooping. 16 with a foot plate and 17 with a handle is designated. That Body wrapping cloth 12 can be divided into numerous strips that run parallel or as a mesh or as a grid or are arranged in a different shape, or it can be formed with a window. It is also possible to use the Body wrap can be used on a concave fluoroscopic table or in a room separate from the surface of the fluoroscopic table.

According to Fig. 2 surrounds in a further embodiment Body wrapping sheet 12 the upper and lower sides of a bed 1. There are seven rotating shafts 5 which

-ιοί are arranged parallel to each other, that is, two upper ones Rotary shafts 5a, four side rotary shafts 5c and one driven rotary shaft 5d. The upper rotating shafts 5a are arranged between bearings 18 on frame arch 4 on the head and foot sides. The bearings 18 are on the frame arch 4 slidably arranged and normally moved to the lower transverse side of each frame sheet 4 and can towards each other be moved. The distance between the upper rotating shafts 5a is 60-80 cm. The side rotating shafts 5c are arranged slightly outside the transverse surface of the bed 1 and parallel to the bed 1, so that the body wrap 12 does not touch the two transverse sides of the bed 1. The rotating driven shaft 5d is on the lower side of the center of the bed 1 and arranged via the transmission gear or the drive device 8 with connected to the motor 7, which is also arranged on the underside of the bed 1. A pinion 19 is driven on the Rotating shaft 5d arranged and meshes with holes or openings 20, the at both ends of the body wrapping cloth 12 are provided. Each rotating shaft 5 is arranged in the ring formed by the body covering sheet 12 and a bent part is formed between the upper rotating shafts 5a. In the illustrated embodiment the body-enclosing sheet 12 formed into a ring by a closure device 24 or an adhesive tape and can as a result, can easily be arranged around the rotating shafts / and removed again there.

Fig. 3 illustrates the application of the invention to a gQ stretcher for carrying a patient or the like. On the Table 1 of the stretcher, support posts 21 are provided, which are brought into an upright position and then put down again and a bearing 18 is attached to the top of each support post 21. The support posts 21 are in or laid down transversely to the outside. There are six rotating shafts 5 are provided parallel to each other, that is, two upper rotating shafts 5a, two rotating shafts arranged laterally 5c and two lower rotating shafts 5b. The upper rotating shafts 5a

are rotatably mounted in the bearings 18 at the ends of the support posts 21. When the support posts 21 are upright, the associated rotating shaft 5a is arranged in the highest position; when the support posts 21 are down, the associated upper rotary shaft 5a is in the lowest position. The laterally arranged rotating rollers 5c are on both sides of the table 1 of the stretcher at a level slightly above the surface of the table 1 and arranged parallel to its transverse surfaces and rotatably mounted in bearings 18 which are detachably attached to the table 1 are. One end of each side rotating shaft 5c protrudes from the bearing 18 and is detachably connected to a crank 22. The side rotating shafts 5c are at an appropriate position with the engaging means 13 for engagement provided with the cloth 12. In the embodiment shown

The lateral rotating shafts / the driven ones are the approximate shape Rotating shafts. The lower rotating shafts 5b are on the underside of the table at a smaller distance therefrom as the side rotating shafts 5c rotatably supported in bearings 18. The lower rotating shaft 5b stands with the endless one Body wrapping sheet 12 not in contact when the associated upper rotating shaft is laid down. The body wrap 12 is arranged so that it forms a ring around the rotating shafts 5 and the table 1 and a concave one curved part between the upper rotating shafts 5a.

The operation of the device according to the invention is will now be explained with reference to the embodiments shown in FIGS. When the body 23 is one to be examined Person lies between the upper rotating shafts 5a, this body 23 is in the concave curved part between the upper rotating shafts 5a enclosed over about half or about the entire body thickness. When the body 23 is enclosed on the body wrapping cloth 12, the cloth 12 is stretched around the rotating shafts 5. The engine 7 or the crank 22 are rotated and the rotation is transmitted to the rotating driven shaft. The one on the bottom

Rotary shaft 5b in Fig. 1, the driven rotary shaft 5d on the underside of the bed center 'in Fig. 2 or the side Rotation transmitted to rotary shafts 5c in FIG. 3 is further increased by the engaging parts provided on the rotary shafts 5 or engagement devices 13 on the body wrap 12 transferred.

If a polyvinyl chloride sheet around the outer periphery of the Rotary shafts 5 and the body wrapping cloth 12 are arranged is, the adhesion to the surface of the polyvinyl chloride film, as has already been described, to it can be used to transmit the rotating force of the rotating shafts 5 to the body enclosing sheet 12 to be moved.

When the rotating shafts 5 rotated and thereby the body wrap 12 are moved in the concave curved shape, the body is on the cloth according to the Law of rotation of a rigid body rotated. Reverse rotation or stopping can be done in the same way take place. When the movement range of the towel is read numerically, the body position in can be selected inclined positions can be chosen repeatedly.

Fig. 6 (A) and (B) illustrate schematically the underlying Circular movement of the cloth. If a track for the place of cloth movement on the table or around the perimeter of the table is placed and both ends of the cloth are moved and displaced on the web, according to the invention is the human body rotated.

If, as in the embodiment with stretcher according to FIG. 3, the two upper rotating shafts 5a can be moved up and down the body wrap sheet 12 can be rotated when a pair of support posts 21 are laid down and the other pair of support posts is upright (Fig. 4, 7) or when both pairs of support posts 21 are upright (Fig. 8) or when both pairs of support posts 21 are put down (Fig. 9). Additionally, if a pair of

Support post 21 is upright and the other pair of support posts 21 is laid down and the body wrap 12 is rotated, a body 23 moves laterally and, when another table is laterally fixed in contact will be transmitted easily and safely.

Figures 10 illustrate various arrangements between the body wrap and the rotating shafts. According to 10 (A) and (B), when the cloth is moved, the body is moved in the transverse direction and falls off the table.

According to Figures (C), (D) and (E), the body in the Cloth twisted. According to Figure 10 (F), the body slips to the transverse side and cannot be rotated well because the cloth Does not have enough tension and is loose.

Fig. 4 shows an embodiment of the invention, which is carried out on a fluoroscopy table, anti-scatter table, diagnostic table, a physical treatment table or the like already fixed horizontally is. According to FIG. 4, the device 2 for rotating a human body has approximately the same dimensions like table 1 and is attached to table 1. Two parallel rotating shafts 5 are at a distance of 40-6 0 cm from each other and releasably attached between the front frame 4 by means of bearings 6. Every rotating shaft consists of a rigid material such as iron or stainless steel, has a length of about 200 cm and measures in Diameter 20-50 mm. The rotating shafts 5 may have a polygon or a flattened shape in cross section.

oQ One end of a rotating shaft 5 appropriately stands from the bearing 6 and is connected to the protruding part with a rotary drive device 7. The rotary drive device 7 is a crank 22 when the rotating shaft 5 is rotated manually, or a transmission (not shown)

gc or such a drive device in combination with a motor and a sprocket when the shaft 5 is electrically rotated. The crank 22 can be used together with a stop device, a braking device or a

Ratchet mechanism or the like can be provided. The body wrap 12 is used to enclose a body and has a rectangular cross-section a length of about 180 cm, that is, slightly less than that of the rotating shafts 5 and a width of about 200-300 cm. The opposite side ends are fixedly attached to the two parallel rotating shafts 5, respectively. When a rotating shaft 5 is rotated, the body wrap sheet 12 is rolled up on this rotating shaft 5. As it is illustrated by arrows in a model representation of FIG. 5, is the direction of rotation of the rotating shafts 5 intended for rolling up the cloth so that the body wrap 12 first over the top of the rotating shafts 5, then to the outside, lower side and Inside is guided one after the other.

When the rotating shafts 5 are detachably attached to the end frame 4, they can be removed and placed on the transverse side of the fluoroscopic table 1 are placed so that a person to be examined can easily climb up on the table 1 or can descend from this. This also makes it possible to use the fluoroscopic table in the usual way. When a person to be examined is on the body wrap 12 has placed on the fluoroscopic table 1, the rotating shaft 5, which has been set aside, is again in the Bearing 6 is inserted and the crank 22 is rotated to adjust the body wrap 12 in a suitable manner tighten. The person to be examined then lies between the two parallel rotating shafts 5 and becomes about halfway of the body enclosed by the body wrap 12 and lies here on the fluoroscopic table 1. If in this arrangement the fluoroscopic table 1 is a scatter table, then one on the underside of the Transillumination table 1 arranged film cassette receiving plate used in operation without obstacles and can be removed again. If the fluoroscopic table 1 is not equipped with an anti-scatter grid, the floor area can consist of two floor panels, like this

that the film cassette receiving plate between the two
Floor plates is used.

The device according to the invention for turning a slim body is based on the principle of rotational movement
of a rigid body, which is illustrated with the aid of the model shown in FIG. 5. The body wrapping cloth can transmit the tangential force F * to the large body by means of the rotating action of the two bearings. If the radius of the rotational movement caused by the force is r,

results for χ r. This principle is used to turn the body used.

The device according to the invention has the following advantages on:

(1) A person lying in bed can change his position easily and safely without the need for substantial physical strength. The body position of a patient seriously weakened by illness, a physically disabled person, an elderly person or a child can increase
easy way to be changed.

(2) Repeatedly changing the position of the body on a fluoroscopic table, what about the X-ray examination of the

Digestive tract required can be easily and accurately be carried out without considerable physical strength being required. The device for turning a human Body has a remarkably simple structure and can be made at a very low cost compared to the Costs are produced that are necessary for known, usual for the examination of the digestive tract facilities are.

(3) Since the person to be examined lies securely in a transparent cloth and is therefore away from someone from the bed Body can be observed, is prevented from auxiliary persons are exposed to X-rays.

(4) Since postures of the body in an inclined position can be repeated in a simple manner, the inventive Device used for fluoroscopy, radiation therapy and other physical examinations and Treatments that require special postures can be used effectively.

(5) Because the body wrap sheet is provided in an endless shape the fabric can be rotated in any direction at any time, regardless of the position it is in . It is not necessary to roll back the cloth. It also prevents parts of the to be examined Person wearing clothes or the like can be caught while rotating.

(6) Plastic sheet material made of polyvinyl chloride can be used with advantage to be used. The device is simple in construction, excellent in safety, and easily clean to keep as a medical instrument. The cloth will not be wrinkled or deformed during rotation. The cloth is held in a concave curved shape when the device is in operation.
