Description

The invention relates to an attachment/cover for placing on a patient couch, in particular a mobile one, with the features of the preamble of claim 1.

When transporting and during the initial medical care and/or treatment of a wounded person (hereinafter referred to as patient), patient couches or stretchers are usually used. For linguistic simplification, the terms "stretcher" and "patent couch" are used synonymously in connection with the invention.
In order to transport or care for the patient, the patient is positioned on a lying surface of the patient stretcher or couch. If the patient has sustained an injury and is bleeding profusely, the patient couch will become contaminated with blood, other bodily fluids, and/or fluids (e.g., IV fluids) administered to the patient.
Medical equipment, monitoring systems and other things are often attached to modern patient beds or stretchers. This includes various hoses and electrical lines, which of course have to be thoroughly cleaned and partially sterilized before each use. This cleaning and sterilization is very time-consuming and expensive if these devices are contaminated by the liquids mentioned above during use. From the U.S.A. 4,714,850 a double-walled, flexible tub is known in which patients can be washed.
From the the U.S. 4,170,045A a bathtub is known which is hung in a tubular frame mounted on rollers.
The DE 20 2006 002 490 U1 discloses a stretcher for patients with a mobile base and a lying surface. The lying surface can be designed as a liquid-tight pan and/or form a collecting container for liquids.

The object of the present invention is to further develop the known stretchers with a view to possible areas of use and flexibility.

In particular, contamination of the patient bed and/or the medical equipment attached to it should be prevented or at least minimized and/or cleaning and sterilization after use should be simplified.

According to the invention, this object is achieved by an attachment for placing on a patient couch, in particular a mobile one, with the features of claim 1 . The attachment according to the invention has an upper side and an underside, the upper side having at least one trough-shaped depression with a bottom. The invention provides that side walls are formed on the long sides of the attachment, that, starting from the base, a first area of the side walls extends upwards and the trough-shaped depression laterally delimits that a second area of the side walls projects downwards beyond the base , and that a clear width between the second areas of the side walls is greater than a width B of a patient bed, a hospital transporter and/or a NATO stretcher.

This geometric constellation makes it possible to place the attachment on a patient bed, a hospital transporter or a NATO stretcher. Due to the second areas of the side walls protruding downwards, there is a form fit between the couch or the transporter or a stretcher and the attachment according to the invention. This means that the attachment cannot slide off the couch. On the other hand, the attachment covers the couch, the hospital transporter or the stretcher so that they are protected from contamination by blood, urine or infusion fluids.

The relatively large overall height of the side walls, which is composed of the first area and the second area, gives the attachment according to the invention high flexural rigidity at the same time, because the attachment is designed in cross section similar to a double T-beam.

In a further advantageous embodiment, end walls are formed on the end faces of the at least one trough-shaped depression, with a first region of the end walls extending upwards from the base and delimiting the trough-shaped depression, with a second region of the end walls protruding downwards beyond the base and a clear width between the second areas of the end walls is greater than a length of the patient bed or a hospital transporter. As a result, a form fit between the attachment and the bed or the hospital transporter can also be produced in the axial direction. As a result, the attachment cannot unintentionally slip off the hospital transporter carrying it or the patient couch in this direction either.

In addition, the side walls or the second areas of the side walls, both in the case of the end walls and in the case of the side walls, have the task of protecting the hospital transporter or patient couch located underneath from dirt. Naturally, this is achieved in a particularly effective manner with peripheral side and end walls.

The height of the second areas can be selected according to the overall height of the hospital transporter or the support surface of the hospital transporter or the patient couch.

The trough-shaped indentation on the top of the attachment according to the invention ensures that most liquids are collected in this trough. If it does happen that some liquid runs down the side walls beyond the trough-shaped recess, it is advantageous if drip edges are formed on the lower edges of the side walls and/or the end walls. These drip edges prevent the liquid from dripping onto the floor.

In a development according to the invention, at least two or even more webs are arranged on the upper side of the attachment, with at least two webs extending between the side walls and serving as a support for a trauma transfer board. This makes it possible to place a severely injured patient who is lying on a trauma transfer board and has been fixed there, together with the trauma transfer board, on the attachment according to the invention without having to reposition him beforehand. This makes it easier to provide first aid to a seriously injured person. In addition, the treatment time is shortened.

In order to ensure that the trauma transfer board with the injured patient on it cannot move relative to the attachment according to the invention, locking means for fixing a trauma transfer board are arranged on the webs. These locking means can be rotatable locking lugs, they can be designed as a bayonet catch or as a screw connection.

It is important that they can be opened and locked quickly and are also easy to clean. These requirements are met by bayonet locks, but also by swiveling locking levers.

So that the attachment according to the invention can also hold or carry medical devices, openings, such as fastening holes, for attaching medical devices, are preferably provided on the side walls. Of course, these openings can also be present on the end walls. Hoses or cables from the hospital transporter or a medical device located below the attachment can also be passed through these openings and guided to the patient.

It is also possible for rails, hooks or clamps for attaching medical equipment to be provided on the side walls and/or the end walls. For example, infusion bags can be hung on such hooks. An infusion mast, hose holders and hose guides, collection devices for blood or urine, and a monitor arm for medical devices can be arranged on the rails or clamps. After use, all of these devices can be easily removed from the attachment. The attachment can then be cleaned very well and easily, and the medical devices and hoses can also be relatively easily cleaned and sterilized separately.

In order to be able to lift and move the attachment, be it with or without a patient, it is preferred if grip holes are cut out in the second areas of the side walls and/or the end walls. These grip holes are preferably attached in the region of both ends of the attachment, so that two people can reach into the grip holes at the end of the attachment and lift the attachment with or without a patient and set it down at another location. Handle holes are often more advantageous than handles because the handles are more difficult to clean. The grip holes mean that when the attachment is lifted, the weight force is transferred directly from the side walls to the hands of the person who is lifting the attachment.

If carrying handles are screwed to the side walls, a bending moment occurs when the attachment is lifted, which loads the side walls in addition to the weight of the attachment and patient. The side walls are therefore less stressed by handle holes than when handles are screwed on in the area of the second areas of the side walls.

In a further advantageous embodiment of the invention, it is provided that the second areas of the end walls have recesses. These recesses are preferably dimensioned and positioned in such a way that the carrying handles of a NATO stretcher or another stretcher can protrude over the attachment in the axial direction. It is then easily possible to place the attachment on a conventional stretcher and to transport the patient, who is placed on the attachment, with the aid of this stretcher.

The attachment according to the invention is preferably made of plastic, in particular fiber-reinforced plastic. It is therefore possible to produce the attachment according to the invention from a plate-shaped, fiber-reinforced thermoplastic material by a forming process. Alternatively, it is also possible to use a duroplastic plastic material with a cap Produce fiber matrix by laminating in a corresponding negative form. Both processes are easy to master in terms of production technology.

The method with a forming process from a sheet-like material requires higher tool costs and is therefore easier to automate. Manufacturing by laminating with a thermosetting plastic is more suitable for smaller quantities, since the negative mold can be produced more cheaply.

Alternatively, it is also possible to produce the attachment according to the invention from a sheet metal plate, e.g. made of stainless steel or aluminum, by a forming process.

The openings and recesses are then worked out of the second areas of the side walls or end walls in further production steps, for example by laser cutting. In all embodiments, the hooks, rails and the like can be connected to the side walls of the attachment by screws or rivets.

Further advantages and advantageous configurations of the invention can be found in the following drawing, its description and the patent claims. All features disclosed in the drawing, its description and the patent claims can be essential to the invention both individually and in any combination with one another.

In the 1 an isometric view of a first exemplary embodiment of an attachment 1 according to the invention is shown. This first exemplary embodiment is designed in two parts. It consists of an upper half and a lower half, which are identical in this embodiment. The essay 1 includes a top and in the 1 invisible underside. Several trough-shaped depressions 3 are formed on the upper side. A bottom of the trough-shaped depression is marked with the reference number 5 . The floor 5 delimits side walls 7 and end walls 9.

When speaking of top and bottom in connection with the invention, and the terms top and bottom are used, then the normal position of use of the attachment is meant in each case. In all figures the attachment is shown in its normal position, i.e. the top is up and the bottom is down.

From the synopsis of 1 until 3 It is easy to see that the side walls 7 and the end walls 9 project upwards somewhat beyond the base 5 so that they form a peripheral edge that delimits the depression 3 .

The trough-shaped depression 3 is used to collect liquids (blood, urine, infusion liquids and other liquids) that accumulate during the medical first aid of a seriously injured patient. The patient is not shown in these figures. In the 2 is a side view of a cap 1 is shown, which is made in one piece. Otherwise, the structure of the exemplary embodiments according to FIG 1 and 2 even. In the 1 it is easy to see that two webs 11 are formed on the upper side of the attachment 1 . These webs 11 divide the trough-shaped depression 3 into a plurality of depressions 3.

The webs 11 form a support for a trauma transfer board (not shown in 1 and 2 ) be. In addition, the webs 11 stiffen the attachment 1 where the weight forces are introduced into the support 1 by the trauma transfer board. In the side view according to 2 the webs are also indicated in the drawing.

The 3 shows a cross section through a further exemplary embodiment of an attachment 1 according to the invention. Structural features of the attachment 1 can be seen clearly on the basis of this cross section. It can be seen on the one hand that the side walls 7 in a first area, which is located above the floor 5, and a second area 15, which is located below the floor, divided mentally. The first area 13 protrudes upwards over the bottom 5 of the trough-shaped depression and thus laterally delimits the trough-shaped depression. The same applies to the first areas 17 of the end walls 9.

Below the base 5, second areas 15 of the side wall 7 are clearly visible. These second areas protect a patient bed or a hospital transporter or a stretcher located under it from soiling. At the same time, they also prevent the attachment 1 from slipping down or slipping sideways relative to the patient bed, a hospital transporter or a stretcher. For this purpose it is helpful if a clear width W between the second areas 15 of the side walls 7 is greater than a width B of a stretcher, a patient bed or the support surface of a hospital transporter.

The same applies to the end faces 9. They also have second areas (not visible in 3 ) that protrude down over the bottom 5 of the essay 1. As a rule, the distance between the second areas of the end walls 9 is greater than the length of a support surface of a hospital transporter or a patient bed.

In the 3 it is also easy to see that the lower edges of the second areas 15 are designed as a drip edge 19 . Smaller quantities of liquid that run out of the trough-shaped recess via the side wall or the end wall can be collected in this “L”-shaped drip edge 19 . When this storage volume of the drip edge 19 is filled, the liquid runs over the drip edge 19 and then drips onto the floor at the outermost area of the drip edge without soiling the patient bed located under the attachment 1 or a hospital transporter.

In the 4 and 5 further exemplary embodiments of one-piece attachments according to the invention are shown. The top of these essays 1 largely corresponds to those in the 1 and 2 illustrated embodiments. In the embodiment according to 4 7 grip holes 21 are present on the second areas of the side walls. In the embodiment according to 5 If there is a large recess on each of the end walls 9, this recess 23 makes it possible to place the attachment according to the invention on a NATO stretcher, as is the case, for example, in FIGS 13 and 14 is shown.

In the embodiment according to 5 the end walls 9 and the side walls 7 are designed to be continuous. Two handles 25 are arranged on the end walls 9 . They allow the attachment 1 to be lifted.

Furthermore, rails 27, hooks 29 and other fastening means (without reference numerals) are arranged on the side walls 7. Medical devices, but also bags with infusion solutions or collection bags for collecting blood or urine can be attached to these attachment means. The fastening means are marked with the reference number 27 . Regardless of whether it is rails, hooks or other fasteners.

In the 6 and 7 a further exemplary embodiment of an attachment 1 according to the invention is shown. In this attachment 1, a monotor arm 29 is arranged on one end wall. This monitor arm 29 can be rotated and makes it possible to hold various devices, in particular monitors. The monitor arm 29 is preferably height-adjustable, so that the display of the monitor 31 can be set at the optimum height for the person treating it.

Bags and equipment (without reference numbers) are hung on the fastening means 27, for example. A patient is located on a trauma transfer board 33 above the attachment 1. This trauma transfer board 33 can, as in FIG 7 shown, are lowered onto the support 1, more precisely, onto the webs 11 of the attachment 1 and are fastened and secured there with locking means 35.

In the 8th and 9 a further exemplary embodiment of an attachment 1 according to the invention is shown. In the figure, a trauma transfer board 33 is shown above the attachment. In the 9 is the trauma transfer board 33 on top 1; ie it rests on top 1.

Based on 8th and 9 it also becomes clear that the outer contour of the attachment 1 does not have to be rectangular, but a head part (top left in the 8th and 9 ) and a foot part can be formed. Furthermore, it is also easy to see that the webs 11 can not only run transversely to the longitudinal axis of the attachment 1, but also a cross-like structure with webs 11 running in the longitudinal direction can be formed.

The 10 shows the embodiment according to FIG 6 and 7 above a hospital transporter (no reference number). In the 11 the attachment is placed on the support surface of the hospital transporter.

The 12 shows that the dimensionally stable and rigid attachment 1 can also be placed on two bearing blocks without an additional substructure.

In the 13 and 14 is presented as per an essay 4 can be placed on a NATO stretcher 41. The handles of the stretcher or the NATO stretcher 41 can protrude beyond the end walls through the recesses 23 on the end face of the attachment.
