Applicant hereby claims foreign priority benefits under U.S.C. �119 from German Patent Application No. 10 2005 053 755.3 filed on Nov. 10, 2005, the contents of which are incorporated by reference herein.
The present invention relates to an upholstery element for a patient bed, for example for a bed of an operating table.
Operating tables typically have a bed which comprises a plurality of segments adjustable in relation to one another. Upholstery elements, on which the patient is supported, are fastened to the various segments. Conventionally, the upholstery elements comprise dimensionally stable integral foam, by means of which suitable shapes and structures can easily be produced. Integral foam has the disadvantage, however, that it is relatively hard, and therefore a patient may acquire pressure marks from being supported on an upholstery element of this type for a lengthy period of time.
In principle, in addition to the integral foam upholstery, a softer upholstery may be used, which is fastened to the integral foam upholstery by means of bands or touch-and-close fastenings. However, fastening means of this type, such as straps, bands or touch-and-close connections, cannot easily be cleaned and therefore present a problem in terms of hygiene. Moreover, the fastening and release of additional soft upholsteries are complicated and therefore time-consuming.
The object on which the invention is based is to specify an upholstery element of the type mentioned in the introduction, which can easily be handled and cleaned and at the same time enables the patient to have a soft support.
This object is achieved by means of an upholstery element comprising a baseplate, two elongate side parts comprising of dimensionally stable foam which are arranged along two mutually opposite edges of the baseplate, and an upholstery part which comprises at least partially of soft foam and fits between the elongate site parts such that it bears at least with its outsides at least partially against the respectively adjacent side part, at least one projecting portion being formed and arranged at least on one side part such that the said portion engages into an associated recess on the outside of the upholstery part when the upholstery part is arranged between the side parts.
In the upholstery element according to the invention, therefore, an upholstery part is provided which comprises at least partially of soft foam and thus enables a patient to have a soft support by means of which pressure points can be avoided. The softer upholstery part acquires a lateral hold due to the dimensionally stable side parts between which it can be placed. At the same time, the upholstery part is retained in this position as a result of the engagement of the at least one projecting portion into its associated recess, without additional fastening means, such as touch-and-close connections, bands or straps, being required. As a result, the upholstery element can be cleaned easily and thoroughly and can be handled in a simple way.
Preferably, the side parts comprise integral foam, in particular PUR (polyurethane) integral foam.
The upholstery part is preferably surrounded by a water-impermeable sheath and can therefore be washed off. It comprises preferably a lower layer of EPDM (ethylene-propylene-terpolymer) and an upper layer of soft foam. The upper layer of soft foam enables the patient to have a soft support. The lower layer comprising the somewhat harder EPDM can engage under the projecting portions of the side parts, with the result that the upholstery part is held more securely during use.
The upholstery part is preferably surrounded by a water-impermeable sheath and can therefore be washed off. It comprises preferably a lower layer of EPDM and an upper layer of soft foam. The upper layer of soft foam enables the patient to have a soft support. The lower layer comprising of the somewhat harder EPDM can engage under the projecting portions of the side parts, with the result that the upholstery part is held more securely during use.
The baseplate preferably comprises a material permeable to X-rays, in particular of plastic, so that the patient, when lying on the operating table, can undergo X-ray examination.
The upholstery element is preferably suitable for being arranged on a segment of a bed of an operating table which is connected in an articulated manner to a further segment of the bed. In this case, a shaped portion is formed on at least one of the longitudinal ends of at least one of the side parts, such that the said shaped portion at least partially covers a joint between the two segments. This prevents a patient who is supported, using the upholstery element, from coming into contact with the joint. Such a shaped portion requires a complex structure since it must allow the various positions of the joint. However, a complex structure of this type can be produced exceedingly well by means of integral foam.
Finally, the invention relates, furthermore, to an operating table with a bed which comprises a plurality of segments adjustable in relation to one another, an upholstery element according to one of the abovementioned developments being arranged on at least one of the segments.
For a clearer understanding of the present invention, reference is made below to the preferred exemplary embodiment which is illustrated in the drawings and which is described by means of specific terminology. It may be pointed out, however, that the scope of protection of the invention is not to be restricted thereby, since such variations and further modifications to the device shown and such further applications of the invention as are indicated in it are considered as the customary current and future specialized knowledge of a competent person skilled in the art. An exemplary embodiment of the invention is shown in the figures in which, to be precise,
FIG. 1 shows a top view of an upholstery element according to an embodiment of the invention,
FIG. 2 shows a cross-sectional view along the line 2-2 of FIG. 1,
FIG. 3 shows a perspective view of the upholstery element,
FIG. 4 shows a front view of the upholstery element of FIGS. 1 and 2 in which the upholstery part has been removed,
FIG. 5 shows a top view of the upholstery element of FIGS. 1 and 2 in which the upholstery part has been removed, and
FIG. 6 shows a cross-sectional view, corresponding to FIG. 2, through a modified embodiment of the upholstery element according to the invention.
FIG. 1 shows a top view of an upholstery element 10 according to an embodiment of the invention, and FIG. 2 shows a cross section through the upholstery element 10 along the line 2-2 of FIG. 1.
The upholstery element 10 is intended to be arranged on a segment of a bed of an operating table (not shown). As shown in FIG. 1 and FIG. 2, the upholstery element 10 comprises a baseplate 12, at the longitudinal edges of which side parts 14 comprising dimensionally stable foam are arranged. In this case, longitudinal edges designate the edges of the baseplate 12 which are arranged in the longitudinal direction of the bed of the operating table when the upholstery element 10 is arranged on the operating table.
The baseplate 12 comprises plastic permeable to X-rays. Radiographs of a patient supported on the upholstery element 10 can therefore be taken through the latter.
The upholstery element 10 further comprises an upholstery part 16 which is arranged, lying on the baseplate 12, between the elongate side parts 14. The upholstery part 16 is surrounded completely by a water-impermeable sheath 18 which can be washed off. It contains a core which comprises a lower layer 20 of ethylene-propylene-terpolymer foam (EPDM foam) and of an upper layer 22 of soft foam. The sheath 18 may be electrically conductive at least on its outer surface.
The upholstery part 16 can be placed onto the baseplate 12 between the side parts 14, as shown in FIGS. 1 and 2, and is held in this position in a way described in more detail below. The upholstery part 16 can be removed from this position, for example for cleaning.
FIGS. 3 to 5 illustrate the upholstery element 10, with the upholstery part 16 removed. In this case, FIG. 3 shows a perspective view of the baseplate 12 and the two side parts 14. FIG. 4 shows a front view, that is to say a view from the viewing direction of the arrow 24 of FIG. 3, and FIG. 5 shows a top view of the baseplate 12 and the side parts 14.
As already mentioned above, the side parts comprise dimensionally stable foam, from which the structured shape of the side parts 14, which is to be seen in FIGS. 3 to 5, can easily be produced. Preferably, the side parts 14 comprise a structured foam or integral foam with a solid, non-foamed outer skin, for example of PUR (polyurethane) integral foam. As shown in FIGS. 3 to 5, the side parts 14 each have an inwardly directed side 26 on which three projecting bosses 28 are formed in each case. The bosses 28 have a convex, for example part-spherical configuration. The side parts 14 may be lacquered with an electrically conductive lacquer, so that, in conjunction with the electrically conductive sheath 18 of the upholstery part 16, statutory electrical conduction discharge is obtained on the surface of the upholstery element 10.
A shaped portion 30 is formed in each case at one of the longitudinal ends of the side parts 14. The shaped portion 30 is intended for partially covering a joint which is arranged between two adjacent segments (not shown) of the bed of an operating table. This ensures that a patient supported on the bed does not come into contact with the joint. The complex structure of the side parts 14, which is shown in FIGS. 3 to 5, can be produced in a relatively simple way from integral foam.
The bosses 28 are intended for retaining the upholstery element 16 when the latter is arranged, lying on the baseplate 12, between the side parts 14, as shown in FIGS. 1 and 2. In this position, the bosses 28 engage into associated recesses 34 of the upholstery part 16 which are formed on the outside 32 of the upholstery part 16 (see FIG. 2). This prevents the upholstery part 16 from slipping out of place in relation to the baseplate 12 and to the side parts 14. A contribution to this is made, in particular, by the lower layer 20 of the upholstery 16, which comprises EPDM foam and is therefore more rigid than the viscoelastic soft foam of the upper layer 22 and which engages under the bosses 28.
The upholstery element 10 from FIGS. 1 to 5 thus has a middle lying portion which is formed by the soft upholstery part 16 and on which a patient can be supported for a long time, without pressure marks being formed on his body. At the same time, the upholstery element has the more rigid side parts 14, by means of which the upholstery part is retained in its predetermined position and which gives the upholstery part 16 a lateral hold. Furthermore, the side parts 14 have a suitable structure, in order to cover further components of the operating table (not shown), for example longitudinal spars of the segments or joints between the segments.
In a modified embodiment illustrated in FIG. 6, the upholstery part 16 has a T-shaped cross section, the T-foot of which lies between the side parts 14 and the T-crosspieces of which cover the side parts 14, so that, as seen in a top view, the upholstery element 10 has a closed surface. This solution has hygienic benefits, since body fluids and other fluids or impurities cannot penetrate into the gaps between the side parts 14 and the upholstery part 16.
The upholstery part 16 is held securely on the upholstery element 16 without straps, touch-and-close connections or the like which cannot easily be cleaned.
Although a preferred exemplary embodiment is shown and described in detail in the drawings and in the above description, this is to be considered as purely illustrative and not as restrictive of the invention. It is pointed out that only the preferred exemplary embodiment is illustrated and described, and all variations and modifications which come in the present time and in future within the scope of protection of the invention are to be protected.
