Description

Sick bed

Description

The invention relates to a hospital bed with a bed frame, a frame which can be moved vertically and lowered to the height of a toilet bowl, and a multi-part mattress lying thereon, the head part of which can be pivoted.

In US Pat. No. 4,085,471, such a patient bed is described and illustrated with a further variant. This hospital bed is apparently arranged stationary above the toilet bowl and has a mattress consisting of a head part and a foot part. To perform the emergency, the patient must first be lifted onto this bed, whereupon his legs are raised by means of a swiveling support. The foot part released in this way is then first lowered via a scissor joint and then moved under the head part by means of a slide, whereby the toilet bowl is released. Subsequently, the patient's legs are first lowered again and held in a horizontal position by means of the support, so that the frame carrying the head part and the support is then moved to the height of the toilet bowl. In a further step, the head section is pivoted upwards and the legrest is pivoted downwards so that the patient lent a sitting position on the toilet bowl. After relieving the emergency, the patient is brought back into his lying position in the reverse order in order to be subsequently transferred to his bed.

In a variant of this known hospital bed, the mattress is constructed in three parts, the foot part consisting of a leg rest replacing the support and a buttock rest which can be swung away.

The subject of DE-OS 29 35 554 is a hospital bed with inte¬ grated toilet bowl, which is arranged under a ^'opening in the mattress. In order to provide access to the toilet bowl, an approximately cylindrical mattress part from a cutout of the mattress is first moved downward and then to the side, in order then to pivot the toilet bowl from below into the cutout of the mattress. A disadvantage of this bed is the fact that the patient does not assume a sitting position when he is relieved.

The invention has for its object to provide a bed of the type outlined at the outset, which can be used as a permanent hospital bed and, with the greatest possible mobility, allows the patient to do the emergency in a seated position and without outside help.

According to the invention, this object is achieved in that the bed frame of the crane bed designed for the permanent bed stay can be moved over the toilet bowl and that the mattress in the buttocks area of the patient has an extendable mattress part which releases a passage opening to the toilet bowl. Such a hospital bed has the considerable advantage of a much simpler and therefore less expensive construction compared to the prior art explained at the outset and is primarily intended to serve as a permanent hospital bed for the patient without the patient having to relieve himself must be bedded. Usually the bed will always be above the toilet bowl. If this is not the case, then it is sufficient, if necessary, to move the patient's bed over a toilet bowl in order to then open the passage opening to the toilet bowl and to bring the patient into a seated position.

Compared to the prior art mentioned above, it is advantageous that the toilet bowl does not have to be integrated in the bed, as a result of which odor nuisance is avoided. It is of particular importance, however, that the patient is able to relieve himself when he is sitting, which is essential from an anatomical point of view for a perfect process, because only. when seated, the rectum assumes an approximately vertical position and the buttocks are spread, so that the least possible contamination is ensured. Finally, it is essential that the patient can relieve himself without any outside help.

In a further development of the invention, the bed frame can be coupled to a chassis which carries the toilet bowl and a flushing and ventilation center connected to it, in which devices for controlling the sequence of all functions of the bed are accommodated.

With this combination, a mobile sanitary unit is available that combines the bed and all the organs required for supply and disposal as well as for function control. Further features and advantages of the invention result from the subclaims and from the following description of exemplary embodiments which are shown in the drawing.

Figure 32 shows the flow matrix of the system. FIG. 1 shows a side view of a sickbed 10 with a bed frame 14 that can be moved on wheels 12. The bed frame 14 carries an electric motor 16 on the head and foot side for driving a spindle 18, with the aid of which a frame 20 can be raised or lowered. A mattress 22 lies on the frame.

When the frame 22 is raised, the patient bed 10 can be moved over a toilet bowl 24, as the variant of FIGS. 2 and 3 shows.

The mattress 22 has, in the buttocks area of the patient lying on it, an extendable mattress part 26 which can have a round, oval or even rectangular outline. This mattress part 26 can at the same time be moved down and horizontally out of the mattress 22 by means of an electric motor 28 and a threaded spindle 30, which drives a positively guided link chain 32, in order in this way to provide a passage opening 34 (cf. figures 9 - 11) to the toilet bowl 24.

A remote control device 38 with push buttons 40 for actuating the individual electric motors 16, 28 by the patient hangs on a gallows 36 above the head end of the patient bed 10, which is intended for the patient to stay in bed permanently.

In Figure 1 it is indicated that the toilet bowl 24 is connected to a flushing and ventilation center 42. From this, a flushing water line 44 leads in a known manner to the toilet bowl 24, while a sewage pipe 46 leads either directly or - as indicated in FIG. 1 - into the sewer system via a faecal clarification device 48. Furthermore, an air suction line 50 is connected to the toilet bowl 24, which leads to a suction fan (not shown) in the control center 42. A hot water pump, not shown, is also installed in this, which leads via a hot water line 52 to a hot water shower in the toilet bowl 24. Finally, a warm air line 54 is provided which, after the cleaning rinse by means of the hot water shower, ensures that the buttocks dry.

The aggregates of the flushing and ventilation ^'centrally e mentioned 42 kön¬ NEN be actuated via the remote control device 38th

FIGS. 2-4 show an embodiment of the bed frame 14, the two longitudinal bars 56 of which are connected at the head end by a cross member 58, which is arranged higher than the longitudinal bars 56 for driving over the toilet bowl 24.

In the variant of the patient bed 10 shown in FIGS. 5 and 6, the height-adjustable frame 20 can be moved vertically relative to the bed frame 14 by means of a cable 60. To this end, the bed body 14 includes two driven by a motor, not shown disks 62 are provided for the cable 60 at the foot end of which is led out of the cable 60 over guide rollers 64 at the head end and foot end of the frame ^* 20th The two disks 62 are fastened to a common drive shaft, as a result of which a synchronous drive is guaranteed on both sides of the bed.

FIGS. 7-10 show the sequence of the individual steps in the actuation of the patient bed 10. First, this is moved with the frame 20 raised over the toilet bowl 24 (FIG. 7). Of course, it is also possible to push a portable toilet bowl 24 under the bed 10. Guide and end stops indicated in FIG. 7 ensure that the patient bed 10 and with it the passage opening 34 have a precisely defined position above the toilet. has bowl 24.

Now, as FIG. 8 shows, the mattress center 26 in the patient's buttocks area is extended downwards and at the same time horizontally. For this purpose, the electric motor 28 is switched on, whose threaded spindle 30 actuates the link chain 32. This consists of a support member 66, on which the mattress part 26 is fastened, and a sliding member 70 connected thereto via a joint 68. This joint chain 32 is shown in more detail in FIGS. 17-20. It can be seen that the sliding member 70 is designed as a rectangular frame, a downwardly projecting lever 74 is attached to the horizontal leg 72, on which the threaded spindle 30 engages. The sliding member 70 engages at the level of its leg 72 via lateral guide rollers 76 in a horizontal section 78 of a longitudinal guide 80, the horizontal sections 78 of which in the direction toward the head end of the patient bed 10 each lead into a section leading obliquely upwards 82 pass over. Two lateral guide rollers 76 ^' engage in the two inclined sections 82 of the longitudinal guide 80 and are arranged on the end of the support member 66 opposite the joint 68.

As FIG. 8 shows, at the beginning of the rotation of the threaded spindle 30, the support member 66 and with it the mattress part 26 about the two guide rollers 76 ^' are first pivoted downward via the lever 74 and the sliding member 70 connected thereto. Then the articulated chain 32 assumes an elongated shape, in which two guide projections 84 provided on the vertical legs of the sliding link 70 strike the top of the horizontal sections 78 of the longitudinal guide 80 and prevent the articulated chain 32 from buckling downward . In this position, the mattress part 26 is then pulled out obliquely downward from the mattress 22, the guide rollers 76 and 76 ^' rolling in the longitudinal guide 80. When the position of the mattress part 26 shown in FIG. 9 is reached, the passage opening 34 in the mattress 22 to the toilet bowl 24 is free.

The passage opening is closed by means of the mattress part 26 in the reverse order.

After the mattress part 26 lies under the foot part 86 of the mattress 22 (FIG. 9), the frame 20 and with this the mattress 22 can be lowered so that the toilet bowl 24 engages in the passage opening 34 of the mattress 22. This state is shown in FIG. 10.

Then, as FIG. 11 shows, by means of a further electric motor 88 and a threaded spindle 90, which are pivotably mounted on a support 92 of the frame 20, the head end 94 of the frame and with this the head part 96 of the mattress 22 are raised pivoted. The threaded spindle 90 engages in a threaded nut, not shown, which is mounted in a downwardly extending shoulder 98 of the head end 94 of the frame 20.

In the upwardly pivoted end position of the head end 94, the patient resting on the mattress 22 has taken a seated position, his buttocks resting on the seat ring 100 of the toilet bowl 24. In a modification of the above-th actuation erläuter¬ ^'of the air purifier, a switch may be operated by the ring on the Sitz¬ 100 acting pressure, which the air suction is in operation.

FIGS. 12-16 show a variant of the articulated chain 32 for extending the mattress part 26 out of the mattress 22. In this variant, the threaded spindle 30 is arranged eccentrically with respect to the longitudinal guide 80, so that the middle space remains free and has no outstanding, disruptive parts. The threaded spindle 30 is in a joint clearly shown in FIG. stone 126 is used, which is seated with two laterally projecting pins 128 so that it can rotate in bores 130 of the adjacent slide member 70 and an additional slide member 70 ^' parallel to it. A vertical bore 132 is machined into the joint block 126, into which a cylindrical insert 134 is inserted. The cylindrical insert 134 has a horizontal threaded bore 136, into which the threaded spindle 30 is screwed. ⁱ

In this way an angle is moving! i ehe coupling between the threaded spindle 30 and the two sliding members 70 and 70 ^' is formed, which has sufficient play both in the horizontal direction (axis of the two bores 130 aligned with one another) and in the vertical direction (axis of the cylindrical insert 134) Compensate manufacturing tolerances and prevent jamming of the articulated chain 32 when the mattress part 26 is extended and retracted.

The axis of the joint 68 between the support member 66 and the sliding members 70 protrudes laterally outwards through the links mentioned and is formed on the two outer sides as a guide projection 84 ^'which replaces the guide projection 84 on the sliding member 70 of FIGS. 17-20. When the mattress part 26 is extended, this guide projection 84 ^' , which is designed as a roller, runs on both sides on a guide ramp 102 which is attached to both horizontal sections 78 of the longitudinal guide 80. This prevents the articulated chain 32 from buckling downward. Conversely, when the mattress part 26 is retracted into the passage opening 34 of the mattress 22, the guide ramp 102 ensures that the support member 66 is deflected upward in the joint 68 in good time. A horizontal end section 138 adjoins the inclined section 82 of the longitudinal guide 80 at the level of the frame 20, into which the two lateral guide rollers 76 ^' , which are arranged on the end of the support member 66 opposite the joint 68, enter when the mattress part 26 the passage opening 34 closes.

In the embodiment of FIG. 21, a chain drive 104 is provided instead of the threaded spindle 30 for actuating the articulated chain 32.

FIG. 22 shows a further alternative for the articulated chain 32, which is designed here as a parallelogram guide with a coupling link 105 parallel to the support link 66. When the passage opening 34 is closed, the left end of the parallelogram in FIG. 22 comes to rest against a fixed stop 107, so that the sliding member 70 is pivoted about its lower hinge point 109 until the vertical end position of the support member 66 is reached. A stop 106 prevents the sliding member 70 from swinging downward.

In FIG. 23 it is indicated that there is also the possibility of moving the mattress part 26 under the head end of the bed instead of under the foot end. In this case, there is the possibility of designing not only the head part 96 of the mattress 22, but also the foot part 108 thereof, in order to allow the patient a sitting position while the need arises.

FIG. 24 shows the possibility of accommodating the toilet bowl 24 in a room that has no connection for the disposal of the toilet. In this case, the sewage pipe 46 coming from the sewage treatment device 48 can reach the sewage line of a wash basin 110 or dg1. are connected, during which the tap 112 is connected to the control center 42 via a fresh water line 114. In Figure 25 it is indicated that the toilet bowl 24 with the attached faecal shredding device 48 and the flushing and ventilation center 42 can be accommodated in a room without any supply and disposal connection. In this. In this case, a fresh water tank 118 resting on a mobile frame 116 provides the necessary supply of the water to the control center 42 or to the toilet bowl 24, while a container 122 also resting on a mobile frame 120 holds the faeces egg nerungseinrichtung 48 coming wastewater pipe 46 opens, is used to hold the feces. Both containers 118 and 122 can be designed as barrels rotatable about their longitudinal axis, which facilitate emptying. A pump 124 is shaded into the rinse water line 44 between the fresh water tank 118 and the control center 42.

The chassis of both the Schwasserbehäl age 118 and the container 122 is designed so that it fits through each door and can be driven over a toilet bowl. By means of a drainage device, e.g. of a ball valve 140 indicated in FIG. 27, the waste water can then be emptied from the container 122 into the toilet bowl 24.

The container 122 has an activated carbon filter 142, which cleans escaping air when the faeces are pumped in and thus makes it odorless.

Figures 26 and 27 show a variant of the container 122 for receiving the feces. This container 122 is stored upright on the frame 120 and has a filling and cleaning opening 144 at the top. The line 146 extending from its bottom has a coupling device 148 behind the ball valve 140, with which the line 146 can be connected to the waste water pipe 46. If the container 122 is to be emptied, it is moved, as indicated in FIG. 27, after the ball valve 140 has been closed and the coupling device 148 has been disconnected, via a toilet bowl 24. The ball valve 140 is then opened so that the faeces can run out of the container 122 into the toilet bowl 24.

In the embodiment shown in FIG. 28 for the fresh water tank 118, a standing arrangement of the tank is also provided, which has a filling opening 150 on its upper side. A line 152 leads from its base to the pump 124 attached to the frame 116, from which a supply line 154 emerges, which establishes the connection with the flushing and ventilation center 42.

FIGS. 29, 30 and 31 show a further, very advantageous variant of the invention. This consists in that the toilet bowl 24 and the flushing and ventilation center 42, which in addition to the above-mentioned units also contain all the devices for controlling the sequence of the functions of the bed, are attached to a common chassis 156. As shown in FIGS. 30 and 31, this chassis can be moved under the bed frame 14. In order to ensure the exact positioning of the bed frame 14 relative to the chassis 156, the chassis 156, as indicated in FIG. 30, has a guide ramp 158 on both sides, on the one of which points towards the flushing and ventilation center 42. End seat 160 is provided. In each of the two seats 160, the leg 162 of the bed frame 14 carrying a wheel 12 in front is inserted in the insertion direction F. When both legs 162 are in their prescribed position in the respective seat 160, they become a mechanical coupling locked, for example in the form of a pawl 166 loaded by a spring. In addition, in the locked position, each leg 162 actuates a switch 164 which is used for electrical locking between the bed frame 14 and the chassis 156. In this position, which is shown in FIG. 31, the patient bed 10 and the chassis 156 form a mechanically rigid unit which, as such, can be moved to any desired location.

If the bed 10 is not in the precisely prescribed position relative to the chassis 156, at least one of the two switches 164 is not actuated, so that no electrical locking takes place. This prevents any electrical device in the flushing and ventilation center 62 from being switched on.

The diagram in FIG. 32 shows the sequence matrix of the human-machine system with the patient bed and the associated sanitary facility according to the invention.
