FORM-STABLE ATTACHMENT / COVER FOR A PATIENT COUCH

Description

[0001] The invention relates to an attachment / cover for placing on a, in particular mobile, patient bed, with the features of the preamble of claim 1, a patient bed with a corresponding attachment having features of the first dependent claim and a patient bed with a corresponding attachment and a dimensionally stable patient stretcher having features of the second dependent claim.

[0002] Patient stretchers or gurneys are typically used during the transport and initial medical care and / or treatment of an injured person (hereinafter referred to as the patient). For the sake of linguistic simplicity, the terms "gurney" and "patented stretcher" are used synonymously in connection with the invention.

[0003] To transport or treat the patient, the patient is positioned on the surface of a patient stretcher or cot. If the patient has suffered an injury and is bleeding heavily, the cot will become contaminated by blood, other bodily fluids, and / or fluids administered to the patient (e.g., IV fluids).

[0004] Modern patient beds or stretchers are often equipped with medical devices, monitoring systems, and other equipment. This includes various tubes and electrical cables, which, of course, must be thoroughly cleaned and sometimes sterilized before each use. This cleaning and sterilization process is very time-consuming and expensive if these devices become contaminated by the aforementioned fluids during use.

[0005] German patent DE 20 2006 002 490 U1 discloses a transport stretcher for patients with a mobile base and a lying surface. The lying surface can be designed as a liquid-tight tray and / or form a collection container for liquids.

[0006] A length-adjustable transport stretcher is known from CN 110 522 571 B. It includes, among other things, a frame and foldable wheels.

[0007] A transport device for transporting patients into a computed tomography scanner is known from CN 111 134 971 A. Document US4819925 discloses an attachment for a patient table with all the technical features of the preamble of claim 1.

[0008] The object of the present invention is to further develop the known transport stretchers with regard to possible areas of application and flexibility.

[0009] In particular, the aim is to prevent or at least minimize soiling of the patient bed and / or the medical equipment attached to it, and / or to simplify cleaning and sterilization after use of the bed. According to the invention, this objective is achieved by an attachment for placement on a patient bed, particularly a mobile one, with the features of claim 1. The attachment according to the invention has a top and a bottom, the top having at least one trough-shaped depression with a base.

[0010] According to the invention, it is provided that side walls are formed on the longitudinal sides of the attachment, that, starting from the floor, a first area of ​​the side walls extends upwards and laterally limits the trough-shaped depression, that a second area of ​​the side walls projects downwards beyond the floor, 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.

[0011] This geometric configuration makes it possible to attach the cover to a patient bed, a hospital transport vehicle, or a NATO stretcher. The downward-projecting second sections of the side walls create a positive fit between the bed, transport vehicle, or stretcher and the cover according to the invention. This means that the cover cannot slip off the bed. Furthermore, the cover protects the bed, hospital transport vehicle, or stretcher from contamination by blood, urine, or intravenous fluids.

[0012] The relatively large height of the side walls, which are composed of the first area and the second area, simultaneously gives the attachment according to the invention a high bending stiffness, because the attachment is designed in cross-section similar to a double-T beam.

[0013] In a further advantageous embodiment, end walls are formed on the end faces of the at least one trough-shaped recess, wherein a first section of the end walls extends upwards from the base and delimits the trough-shaped recess, and a second section of the end walls projects downwards beyond the base, with a clear width between the second sections of the end walls being greater than the length of the patient stretcher or hospital transport vehicle. This allows for a positive fit between the attachment and the stretcher or hospital transport vehicle in the axial direction as well. Consequently, the attachment cannot unintentionally slip off the hospital transport vehicle or patient stretcher supporting it in this direction either.

[0014] Furthermore, the side walls, or rather the second sections of the side walls, serve to protect the hospital transport vehicles or patient stretchers underneath from contamination, both at the front and back. This is naturally achieved most effectively with continuous side and front walls.

[0015] The height of the second sections can be chosen according to the overall height of the hospital transporter or the support surface of the hospital transporter or the patient stretcher.

[0016] The trough-shaped depression on the top of the attachment according to the invention ensures that most liquids are collected in this depression. If, however, some liquid should overflow the trough-shaped depression and run down the side walls, it is advantageous to have drip edges on the lower edges of the side walls and / or the end walls. These drip edges prevent the liquid from dripping onto the floor.

[0017] In a further development of the invention, at least two or more ribs are arranged on the upper surface of the attachment, with at least two ribs 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 and secured to a trauma transfer board, onto the attachment according to the invention together with the trauma transfer board, without having to reposition the patient beforehand. This facilitates the initial care of a severely injured person. Furthermore, it reduces treatment time.

[0018] To ensure that the trauma transfer board, with the injured patient on it, cannot shift relative to the attachment according to the invention, locking means for fixing the trauma transfer board are arranged on the struts. These locking means can be rotatable locking lugs, bayonet fittings, or screw connections.

[0019] It is important that they can be opened and locked quickly and are also easy to clean. Bayonet locks and swivel locking levers meet these requirements.

[0020] To enable the attachment according to the invention to hold or support medical devices, openings, such as mounting holes, are preferably provided on the side walls for attaching medical devices. These openings can, of course, also be present on the end walls. Hoses or cables from the hospital transport vehicle or a medical device located below the attachment can also be routed through these openings to the patient.

[0021] It is also possible that rails, hooks, or clamps for attaching medical equipment are provided on the side and / or end walls. For example, IV bags can be hung from such hooks. An IV pole, tubing holders and guides, blood or urine collection devices, and a monitor arm for medical equipment can be attached to the rails or clamps. After use, all these devices can be easily removed from the unit. The unit can then be cleaned very thoroughly and easily, and the medical devices and tubing can also be cleaned and sterilized separately with relative ease.

[0022] To enable lifting and repositioning of the attachment, whether with or without a patient, it is preferred that handholds be provided in the second sections of the side walls and / or the end walls. These handholds are preferably located at both ends of the attachment, allowing two people to each grasp the handholds at the end of the attachment and lift it, with or without a patient, and set it down again at a different location. Handholds are often more advantageous than handles, as handles are more difficult to clean. The handholds ensure that when lifting the attachment, the weight force is transferred directly from the side walls to the hands of the person lifting it.

[0023] If carrying handles are screwed onto the side walls, lifting the attachment creates a bending moment that puts additional stress on the side walls on top of the weight of the attachment and the patient. Therefore, the stress on the side walls caused by handle holes is less than if handles are screwed onto the second section of the side walls.

[0024] In a further advantageous embodiment of the invention, the second areas of the end walls are provided with recesses. These recesses are preferably dimensioned and positioned such that the carrying handles of a NATO stretcher or another stretcher can project axially beyond the attachment. This makes it readily possible to place the attachment on a conventional stretcher and transport the patient, who is positioned on the attachment, using this stretcher.

[0025] The attachment according to the invention preferably consists of plastic, in particular fiber-reinforced plastic. It is therefore possible to produce the attachment according to the invention from a sheet-shaped fiber-reinforced thermoplastic material by a forming process. Alternatively, it is also possible to produce the attachment from a thermosetting plastic material with a fiber matrix by laminating it into a corresponding negative mold. Both methods are readily controllable from a manufacturing perspective.

[0026] The process involving forming a sheet-like material requires higher tooling costs but is more easily automated. Lamination with a thermosetting plastic is better suited for smaller production runs because the negative mold can be manufactured more cost-effectively.

[0027] Alternatively, it is also possible to produce the attachment according to the invention by means of a forming process from a sheet metal plate, e.g. made of stainless steel or aluminium.

[0028] The openings and recesses are then machined from the second sections of the side walls or end walls in further manufacturing steps, for example by laser cutting. In all embodiments, the hooks, rails, and the like can be attached to the side walls of the attachment by screws or rivets.

[0029] Further advantages and advantageous embodiments of the invention can be seen from 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. drawing They show:

[0030] Figure 1 is an isometric view of an embodiment of a two-part attachment; Figure 2 is a side view of a one-part attachment according to the invention; Figure 3 is a cross-section through an embodiment of an attachment according to the invention; Figures 4 and 5 are isometric views of further embodiments of attachments according to the invention; Figures 6 and 7 show an attachment according to the invention equipped with medical devices and a patient on a trauma transfer board; Figures 8 and 9 show a further embodiment of an attachment with a trauma transfer board in two different positions; Figures 10 and 11 show the attachment according to the invention above a hospital transport vehicle in conjunction with a hospital transport vehicle; Figure 12 shows an attachment according to the invention placed on two trestles; and Figures 13 and 14 show the attachment according to the invention together with a stretcher.

[0031] In the Figure 1Figure 1 shows an isometric view of a first embodiment of an attachment 1 according to the invention. This first embodiment is formed in two parts. It consists of an upper half and a lower half, which are identical in this embodiment. The attachment 1 comprises a top and a lower half. Figure 1 The underside is not visible. Several trough-shaped depressions 3 are formed on the upper surface. The bottom of one of the trough-shaped depressions is marked with the reference symbol 5. The bottom 5 defines side walls 7 and end walls 9.

[0032] When the invention refers to the top and bottom, and the terms "top" and "bottom" are used, they always refer to the normal operating position of the attachment. In all figures, the attachment is shown in its normal position, i.e., the top is at the top and the bottom is at the bottom.

[0033] From the overall view of Figures 1 to 3 It can be clearly seen that the side walls 7 and the end walls 9 extend upwards slightly above the base 5, so that they form a circumferential rim that limits the depression 3.

[0034] The trough-shaped depression 3 serves to collect fluids (blood, urine, IV fluids, and other fluids) that accumulate during the initial medical treatment of a seriously injured patient. The patient is not depicted in these figures. In the Figure 2 Figure 1 shows a side view of an attachment 1, which is made in one piece. Otherwise, the structure of the exemplary embodiments is as follows. Figures 1 and 2 same. In the Figure 1 It is clearly visible that two ribs 11 are formed on the upper surface of the attachment 1. These ribs 11 divide the trough-shaped depression 3 into several depressions 3.

[0035] The ribs 11 form a support for a trauma transfer board (not shown in Figures 1 and 2). Furthermore, the webs 11 stiffen the attachment 1 where the weight forces from the trauma transfer board are introduced into the support 1. In the side view according to Figure 2 The bridges are also indicated in the drawing.

[0036] The Figure 3 Figure 1 shows a cross-section through another embodiment of an attachment 1 according to the invention. Structural features of the attachment 1 are clearly visible in this cross-section. It can be seen, firstly, that the side walls 7 can be conceptually divided into a first region located above the base 5 and a second region 15 located below the base. The first region 13 projects upwards above the base 5 of the trough-shaped recess and thus laterally defines the trough-shaped recess. The same applies to the first regions 17 of the end walls 9.

[0037] Below the base 5, the second sections 15 of the side wall 7 are clearly visible. These second sections protect a patient stretcher, hospital transport vehicle, or gurney located beneath it from contamination. At the same time, they also prevent the attachment 1 from sliding or shifting laterally relative to the patient stretcher, hospital transport vehicle, or gurney. For this purpose, it is helpful if the clear width W between the second sections 15 of the side walls 7 is greater than the width B of a stretcher, patient stretcher, or the support surface of a hospital transport vehicle.

[0038] The same applies to the end faces 9. They also have second areas (not visible in Figure 3 ) which extend downwards beyond the base 5 of the attachment 1. The distance between the second sections of the end walls 9 is generally greater than the length of a support surface of a hospital transport vehicle or a patient stretcher.

[0039] In the Figure 3 It is also clearly visible that the lower edges of the second sections 15 are designed as drip edges 19. Smaller quantities of liquid that overflow from the trough-shaped recess over the side or end wall can be collected in this "L"-shaped drip edge 19. When this storage volume of the drip edge 19 is full, the liquid overflows the drip edge 19 and then drips onto the floor at the outermost point of the drip edge, without soiling the patient bed or a hospital transport vehicle located under the attachment 1.

[0040] In the Figures 4 and 5 Further embodiments of one-piece attachments according to the invention are shown. The upper surface of these attachments 1 largely corresponds to those shown in the Figures 1 and 2 illustrated embodiments. In the embodiment according to Figure 4There are 7 handle holes 21 on the second sections of the side walls. In the embodiment according to Figure 5 Each of the end walls 9 has a large recess; this recess 23 makes it possible to place the attachment according to the invention on a NATO stretcher, as is done, for example, in the Figures 13 and 14 is shown.

[0041] In the embodiment according to Figure 5 The end walls 9 and the side walls 7 are continuous. Two handles 25 are arranged on the end walls 9. They make it possible to lift the attachment 1.

[0042] Furthermore, 7 rails 27, hooks 29, and other fastening devices (without reference numerals) are arranged on the side walls. Medical devices, as well as bags containing infusion solutions or collection bags for blood or urine, can be attached to these fastening devices. The fastening devices are marked with reference numeral 27, regardless of whether they are rails, hooks, or other fastening devices.

[0043] In the Figures 6 and 7 Figure 1 shows a further embodiment of an attachment 1 according to the invention. In this attachment 1, a monitor arm 29 is arranged on one end wall. This monitor arm 29 is rotatable and allows various devices, in particular monitors, to be mounted. Preferably, the monitor arm 29 is height-adjustable so that the display of the monitor 31 can be adjusted to the optimal height for the personnel treating the patient.

[0044] Bags and equipment (without reference numbers) are attached to the fastening devices 27 as examples. Above the attachment 1, there is a patient on a trauma transfer board 33. This trauma transfer board 33 can be, as shown in the Figure 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.

[0045] In the Figures 8 and 9 A further embodiment of an attachment 1 according to the invention is shown. In this figure, a trauma transfer board 33 is shown above the attachment. Figure 9 The trauma transfer board 33 is located on the appendix 1; i.e., it rests on the appendix 1.

[0046] Based on the Figures 8 and 9 It also becomes clear that the outer contour of the attachment 1 does not have to be rectangular, but rather a headboard (top left in the Figures 8 and 9) and a foot section can be formed. Furthermore, it is also clearly visible that the struts 11 can not only run transversely to the longitudinal axis of the attachment 1, but can also form a cross-like structure with struts 11 running longitudinally.

[0047] The Figure 10 shows the embodiment according to Figures 6 and 7 above a hospital transport vehicle (without reference mark). In the Figure 11 The attachment is placed on the support surface of the hospital transporter.

[0048] The Figure 12 shows that the dimensionally stable and flexurally rigid attachment 1 can also be placed on two bearing blocks without any further substructure.

[0049] In the Figures 13 and 14 is shown how an essay according to Figure 4 It can be mounted on a NATO stretcher 41. The cutouts 23 on the front of the attachment allow the handles of the stretcher or the NATO stretcher 41 to extend beyond the end walls. Reference symbol list
