Description

The invention relates to a ward trolley according to the preamble of claim 1.

The invention relates in particular to hospital operations and to the rationalization of the work processes of nurses, who usually keep or maintain written documentation of the patient(s) accompanied by a doctor. This ward trolley replaces the usual procedure with disorganized pieces of paper and effectively takes into account the cramped spatial situations, particularly at the hospital bed. The ward trolley according to the invention serves as an archiving tool for all data relating to the patients in a care area, such as a hospital ward.

Essentially, the documentation initially consists of hanging files that are kept in a hanging filing cabinet and in which the medical histories of the patients in one of the above-mentioned care units are summarized. The documents are arranged between stiff file covers and, in addition to the medical histories, can also include examination reports from previous hospital stays and other documents.

In addition, the documentation kept in the hospital includes so-called pianettes; these are foldable registers that are put together on a rigid support plate. The registers consist of pockets in which, among other things, the patient's personal course of events, but also diagnoses, the patient's condition during

during the rounds and any medications are noted by the attending physician with the time and date. As a rule, these bags contain up to 10 to 12 progress curves, depending on the number of patients. These charts are normally kept in the nurses' room during hospital operations, but must be taken with you during the rounds and kept ready. Usually, the average occupancy of hospital wards is three to four charts.

Finally, X-ray images must also be kept ready for the relevant visits. Since these are relatively heavy and large documents, X-ray images are usually stored in so-called X-ray bags, which have the format of an oversized envelope.

The mobility of the ward trolley is a prerequisite for a speedy bedside visit. Since during the ward round not only the information that is documented is checked, but also new data must be recorded and recorded, the ward trolleys are equipped with a writing pad that makes it easier to record handwritten information.

The above-described application of the ward trolley according to the invention to hospital operations is not its only intended purpose. With certain modifications to the documentation, the ward trolley can also be used in doctor's offices, nursing homes, retirement homes or the like. For a better understanding, however, the invention is also explained in more detail below using hospital operations as an example.

Visiting trolleys of this type are already known. On a base frame that is wide for reasons of stability and equipped with castors, a cabinet is built on a base plate of the chassis. This cabinet has a pull-out hanging file under a fixed cover plate for the written hanging files. The top of the cover plate is used as a writing surface for the written work that has to be done on site. The planets are hung on hooks on one side of the cabinet. Open compartments at the front are provided for the x-rays, in which the written envelopes are stored standing up. The previously known cabinet structure is made of panel construction on the base plate of the base frame equipped with castors.

This, among other things, results in a significant empty weight of around 90 to 100 kg, which makes working with such trolleys considerably more difficult, as there are also no ergonomically arranged handles for directing the trolley. The cabinet structure is also not high enough, meaning that the lid surface used as a writing surface is at a distance from the floor that is ergonomically and medically unfavorable due to the back problems that cannot be ruled out. The hooks for the pianettes are often not used, which is the case, among other things, when the pianettes in question are full and therefore heavy, as the suspension usually requires the pianettes to be held with one or two fingers in order to be able to hang them up or take them down. The protruding base takes up too much space, which requires complex edge protection and also means that the temporarily unused and parked trolleys get in the way.

When the hanging file is pulled out, there is a risk that if the hanging files are not hung up correctly in the rush of business, they will fall through the file fittings, causing the files to bend and fall to the floor, which must be rejected for hygiene reasons, among other things. It is also not possible to store hanging files in the trolley that exceed the capacity of the hanging file fittings, which is disadvantageous if there are several full hanging files for one or more patients.

With the well-known medical trolleys, the use of the cover plate of the cabinet structure requires that the drawers can be pulled out to one side of the trolley. This leads to the projecting base frame in order to be able to absorb the tipping moments of the heavy drawers with the rollers. The base frame then provides good edge protection for the cabinet structure, but does not ensure that it will not tip over under all circumstances, because the filled hanging file is very heavy and easily shifts the center of gravity of the cabinet from the support surface when it is pulled out.

The invention proceeds differently according to its basic idea, which is the subject of claim 1. Further features of the invention emerge from the subclaims and from the following description .

Because, according to the invention, the pull-outs are movable to one side and the cover plate is extendable to the side opposite the pull-out side, a counter-moment to the pull-outs is created when the cover plate is extended, which, together with the high weight of the immobile parts in the cabinet,

arranged hanging files, the centre of gravity of which lies within the floor plan of the cabinet structure and its roller support, is sufficient to ensure the stability of the trolley, which is why the rollers can also be arranged within the floor plan of the cabinet. This eliminates the need for a bulky base frame, which significantly reduces the weight of the medical trolley and its external dimensions. This has the further advantage that, due to the immobility of the hanging files arranged under the cover plate, the hanging files that are not properly hung cannot fall onto the floor, but onto a cupboard floor that may be arranged underneath.

If, as is usual, pianettes have to be carried, they can also increase the stability of the trolley by implementing the features of claim 2. In this way, the not inconsiderable weight of the pianettes is used to compensate for the moment of the pull-outs and to increase the moment of the cover plate. The weights of the pianettes are introduced directly into the rising wall of the cabinet structure and are therefore located outside the trolley's floor plan to generate the counter moment. The slanted pockets are ergonomically advantageous because they allow the pianettes to be handled with one or even two hands. In this case, it is expedient to ensure with the features of claim 3 that the pianettes lying diagonally in the pockets are protected from the sides, but also that their cover does not allow them to collide with obstacles.

The handling of the ward trolley according to the invention can be made much more ergonomically favorable than before in these and similar embodiments, which is the subject of claim 4

Because the handle can be attached above the bags, but still at an ergonomically favorable distance above the ground, and the handle can be used up to the sides of the cupboard structure, the trolley can be pushed easily and directed in all directions, even by the relatively weak strength of stocky people, despite its high weight.

The tipping tendency of the visiting trolley is also effectively counteracted when the features of claim 5 are implemented. This is because the arrangement of the described organs of the visiting trolley on the narrow sides of the trolley means that any remaining tipping tendency of the visiting trolley exists along the longitudinal axis of the trolley, which leads to tipping over more seriously than with tipping tendencies along the transverse axis of the trolley, which practically cannot occur with the visiting trolley according to the invention.

The ward trolley according to the invention also has a hierarchy oriented towards practical needs, which has the hanging file under the cover plate in an upper horizontal plane, below that another middle level with a generally available storage space and a lower level for storing the x-ray images. The generally available space is used according to the invention to bring the writing pad into an ergonomically favorable position, which is favorably selected according to claim 6. The extendability of the cover plate can be used completely or only partially in individual cases under these circumstances, with the legroom under the extended cover plate offering an ideal standing workstation. The relatively large work surface according to claim 7 "enables free and unhindered work. It also offers

There is also space for storage. This cover plate expediently has the features of claim 8. This is because, in the event of sharp braking maneuvers of the medical trolley, which is basically pushed due to the described arrangement of the handle, the cover plate cannot shoot forwards uncontrollably and cause danger. Since the cover plate is locked in its closed position, the type of locking means that the locking process can be detected acoustically, thus ensuring additional safety.

The features of claim 9 use the hierarchy described above for the lockable storage of utensils, including filled folders and, above all, x-ray images. These images are protected against falling out when the trolley turns and against being taken out without authorization or for no reason by being stored in drawers on the lower cabinet level. This lower drawer can have a relatively large usable height. This is offered by the advantageous options of claim 10. This ensures that the more frequent use of x-ray images only requires a fraction of the extension length of the lower drawer. As a rule, the hanging files are used less frequently. When the features of claim 11 are implemented, the x-ray pockets are securely supported over their full height and can be easily identified thanks to the transparency of the division.

Because, according to the invention, the hanging file is housed immovably in the upper level of the cabinet, the handles of the drawers of the cabinet structure are located below the handle with which, as described above,

the ward trolley is pushed and directed and on the opposite side of the cabinet. Since the handles of the drawers are located within the structure floor plan due to the inward-set front wall and are covered by the side cheeks of the adjoining rising side walls of the structure, improper handling of the ward trolley by pushing the trolley by the handles of the drawers is prevented.

With the help of the features of claim 13, the different requirements for stabilizing the cabinet structure, storing the archiving material in a dust-tight manner and reliably securing the rollers can be easily met. The tray proposed for this purpose, preferably made of stainless steel, reliably holds the rising side walls of the cabinet structure and enables the rollers to be attached directly, for example by screwing the roller cages using screw plates that support the stationary joint member of the swivel roller arrangement.

The details, further features and other advantages of the invention emerge from the following description of an embodiment based on the figures in the drawing; they show

The medical trolley 1 shown in Figure 1 has a cabinet structure 7 that can be moved on four castors 2, 3 in roller cages 5, 6 that rotate around vertical steering axes 4, 5. This has several pull-outs, namely one drawer 8, 9 each, which can be pulled out to the right-hand side of Figure 1. The pull-outs are arranged under a cover plate 10, the surface of which serves as a writing surface and, if necessary, as a storage space for utensils. The cabinet structure 7 also has a hanging filing cabinet 11 that is housed in the cabinet. The cover plate 10 has two parallel guides 12 on its long sides 14. This allows the cover plate 10 to be pulled out in the guides with the help of a handle bar 15 in Figure 1 to the left and thus opposite to the pull-out side 16 on the right in Figure 1, as shown at 17. The side profiles 18 for hanging the hanging files (not shown) in the

&iacgr;&ogr;

Hanging files 11 are fixed in place in the cabinet 7, so that the hanging files are only accessible when the cover plate 10 has been moved into its extended position. The rollers 2, 3 are located within the outline of the base plate 19, which, as shown in Figure 5, is integrated into a tray 20 which has folded-over shorter edges 21, 22 and folded-over longer edges 23, 24.

The four rollers 2, 3 are fastened with their fixed joint plates 25 (Figure 1) with four screw nuts each in the four corners 25 to 28, which are designated 27 to 30 in the enlarged corner 26 shown broken off in the middle. As a result, all rollers 2, 3 are arranged within the outline of the base plate 19. The four bevels 22 to 24 have holes, as shown for example at 31 for the bevel 23. These holes are used to fasten the four rising cabinet walls 32,

33 or 34, 35. Since there is no lateral projection of the chassis formed by the rollers 2, 3 and the trough 30, the side walls 34, 35 above the rollers 2, 3 carry edge protection profiles 36, 37 (Figure 2). The details of these profiles can be seen in the illustration in Figure 9. These are solid profiles 38 with bevelled longitudinal edges 39, 40, which are attached to the associated side walls with the aid of holes, one of which is shown at 41, for example.

34. The front sides of each edge protector are bevelled as shown at 42, 43 in Figure 9 to form guide surfaces.

The planes of the cabinet walls 34 and 35 run parallel to the longitudinal axis of the ward trolley 1, which with the help of a handle 44 can be moved perpendicularly to the

Cabinet walls 32, 33 are preferably pushed to the right in Figure 1 and are thereby directed. According to Figure 8, a tube 45 serves as the handle, which has an ergonomically favorable outline and a handle length that corresponds to the clear distance between each cheek 46, which extends the side walls 34, 35 to the left in Figure 1 on the pull-out side of the cover plate 10.

The ward trolley 1 is also intended for the accommodation of several planettes, which are not shown. This is done using slanted pockets 47 (Figure 1) that are open at the top, the details of which can be seen in the illustration in Figure 7. The slanted pockets are then simple metal sheets 48, the lower edge 49 of which is angled relative to the metal sheet 48. The edge 49 has several holes, as shown at 50, for example, which are used to screw the metal sheet 48 to the rising cabinet wall. As a result of the angle, open receiving spaces 51 for the planettes are formed between the metal sheets 48 and the opposite outer side of the rising cabinet wall 33. If there are several slanted pockets 47 of the type described, the pockets lie on top of one another. They are arranged on the side 17 of the cabinet structure 7 that is opposite the pull-out side 16. The sideways projecting cheeks 46 of the two adjoining rising cabinet walls 34 and 35 cover the receiving spaces 51 of the slanted pockets 47 at the sides. This ensures that the Pianettes cannot slip out of the slanted pockets 47 when cornering.

The handle 44, which bridges the cheeks 46, is located above the slanted pockets 47 and thus in an ergonomically favorable position for pushing and directing the ward trolley 1.

Because the floor plan of the medical trolley is rectangular as mentioned above and the rollers 2, 3 designed as swivel castors are arranged at the floor plan corners 25 to 28, with the pull-out side 16 on the shorter side 21 of the floor plan and the cover plate pull-out side 17 as well as the arrangement side of the slanted pockets 47 and the handle 44 on the opposite shorter floor plan side 22, any tipping tendencies act along the longitudinal axis of the floor plan and are thus largely rendered harmless.

The top of the cover plate 10 has a height of approximately 1160 mm in order to take into account the ergonomic and health requirements of the people who use the cover plate as a writing surface. The total area available for this is approximately 475 x 570 mm.

Not shown is a lid lock, which audibly locks the lid in its retracted position as shown in Figure 1. These are preferably ball snaps, which make an audible noise when they click into place.

The cabinet structure 7 is divided into three horizontal levels for archiving purposes. While the upper horizontal level is provided by a base plate 52 that prevents the hanging files hung in the profiles 18 from falling through, there is a middle horizontal level below that is provided by the base 53 of a drawer 54. The drawer forms the pull-out 8 and is open at the top. It accordingly has side walls 55, 56 and a rear end wall 57. This drawer is used to store utensils of various kinds. It can therefore have a

compartment division. On its front wall 58 there is a handle 59, the details of which can be seen in the illustration in Figure 6. The handle 59 consists of a tube 60, the ends of which are fixed in brackets 61, 62. The brackets 61, 62 are attached to the front wall 58 of the drawer with a screw connection 63.

In a lower cabinet level, which is defined by the base 64 of another drawer 65, which forms the pull-out 9, the archiving of X-ray images takes place in a compartment 66. This compartment is located at the front in the pull-out direction and is separated by its own rear wall 67 from an archiving space 68, which is located between the intermediate wall 67 and the rear wall 69 of the drawer 65. The front wall 70 is higher than the rear wall 69, so that it closes off the front side of the cabinet structure 7. On this front wall 70 there is a handle 71, the design and attachment of which corresponds to the handle 59, which was described above in connection with Figure 6.

As Figure 3 shows, the X-ray images are located in compartments 72. These compartments are created by transparent compartment walls 73, which extend between the intermediate wall 67 and the front wall 70 of the drawer 65 and are attached to profiles 73 and 75 with catches 76, 77 and grooves 78 in a base support 79, into which the compartment walls 73 snap with their lower edge. Each compartment 72 can also accommodate several X-ray bags, in which the X-ray images belonging to a patient are located. The transparency of the walls 73 allows the allocation to the patients to be recognized. The height of the drawer 65 is selected so that the X-ray bags can be set up. On a heifer 80 of the rear drawer

Information signs containing information about the respective X-ray bag can be attached to the box wall 67.

As can be seen from the illustration in Figure 1, the front walls 58 and 70 of the two drawers 54 and 65 protrude inwards behind the associated front wall 32 of the cabinet structure 7. Side panels 74 cover the handles 59 and 71 at the sides and are aligned with the adjacent side walls 34 and 35.

While the embodiment shows a ward trolley intended for hospital use, the trolley can also be used to archive other information material. Therefore, in order to implement the invention, it is not absolutely necessary to store x-ray images or x-ray bags, hanging files containing medical content and planers in or on the ward trolley 1. Rather, other types of archiving equipment can also be stored in the basic design of the ward trolley described above.
