Definitions

  • the present invention relates to a mobile hip bath insert in existing bathtubs with a seat arrangement that can be placed in commercially available bathtubs for independent use by persons who cannot get into conventional bathtubs without outside help, in order to enable them to take a hip bath in self-service.
  • Such mobile hip bath inserts are generally applicable in nursing and elderly care. In particular, however, they are suitable for rental apartments in order to make the growing number of privately living older people independent of their hygienic care and to enable them to use their own apartment even in old age and to maintain a self-determined lifestyle.
  • hip bath inserts are intended for people for whom the sitting position is mandatory for medical reasons when bathing.
  • a hospital bathtub has become known in which an electrohydraulically operated lifting device with hydraulic cylinder, piston rod, and motor-pump unit is attached to a frame supporting the tub body.
  • the hydraulic cylinder has a piston rod that can be ejected upwards, on the upper end of which the supporting structure for a seat and bed is attached, which can be rotated from a position outside the tub body to a position inside the tub body and can be lowered to the height of the tub floor in both positions is.
  • a bathtub lift is a very complex technical device, its use because of its high purchase price and also because of the structural requirements for its installation Measures is restricted. This applies in particular to the bathrooms of privately living people in rented apartments. What would be required would be a device that can be operated easily and safely by the physically handicapped and that is suitable for retrofitting existing bathtubs in rental apartments, both in terms of cost and effort.
  • a bathtub insert is described in European Patent Application No. 0 324 899, which is constructed from a base frame, a lifting plate and guide and lifting devices arranged in between. So that a physically handicapped person can get onto the lifting plate, it must be raised to the level of the edge of the bath tub. The lifting plate is then lowered into the bathing position with the person. When the bath is finished, the lifting plate is raised again to the level of the edge of the bathtub, from where the bathtub can usually be left without outside help - even with restricted mobility.
  • Two guide devices are provided, each in the form of two scissor-like swivel frames - an outer and an inner one - which each have two coaxial fixed bearings on the base frame or the lifting plate and two likewise coaxial sliding bearings on the lifting plate or base frame and by means of handlebars for one joint movement are synchronized.
  • Both swivel frames are rectangular frames, which are articulated to one another in the central area by means of an articulated rod.
  • the inner swivel frame is narrower than the outer swivel frame so that it fits into the lifting plate when it is in the lowered position.
  • the outer swivel frame has two upper fixed bearings and two lower sliding bearings which are guided in rails on the base frame.
  • the inner swivel frame has two lower fixed bearings and two upper sliding bearings, which are guided in corresponding rails on the underside of the lifting plate.
  • the lifting device consists of two pressurized water hoses, the ends of which are attached to the base frame and the lifting plate.
  • the problem with this bathtub insert is that the sliding bearings in the swivel frame the rails they tend to jam, especially when the lift plate is in the up position when the swivel frames are steep. There is then the danger that the lifting plate will be held in its highest position by the self-locking of the sliding bearings when the lifting mechanism is lowered and then will suddenly drop when the self-locking is released, for example by a movement of the person carried by the lifting plate.
  • a spring arrangement is attached to the upper cross member between the two sliding bearings of the inner swivel frame, the other end of which leads to the adjacent upper cross member between the two fixed bearings of the outer swivel frame of the other guide device.
  • This spring arrangement is tensioned when the lifting plate is in the up position.
  • the swivel frame of each guide device can be set very steeply without the sliding bearings jamming in the rails when the pressure water hoses are subsequently relieved, since the spring arrangement prevents or overcomes such jamming. Since the lifting device is driven by the local water network in this bath, its function depends on the existing water pressure. However, this can vary from place to place as well as within a building.
  • a last major disadvantage relates in the same way to both of the above-mentioned sites that define the closest prior art. It consists of the fact that in both cases it is not possible to take a hip bath in conventional reclining bathtubs, with legs hanging freely down and water level reaching to chest level. Such seats are required in many cases, for example with greatly reduced mobility or with cardiovascular problems, and it would be desirable to be able to use conventional bath tubs such as those found in rented apartments.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims solves the problem of creating a hip bath insert which enables physically disabled people to take a hip bath independently in a convenient and safe manner in existing bathtubs.
  • the innovation also aims to design a hip bath insert so that it is inexpensive and can be combined with standard bathtubs without any structural measures.
  • Such a hip bath insert should also be suitable for inexpensive retrofitting of existing bathing facilities, especially in rented apartments for elderly people living privately.
  • This object is achieved according to the invention with the means as characterized in the version of the independent claim.
  • Advantageous further developments are specified in the dependent claims.
  • the hip bath insert according to the invention has the advantage that no special supply and discharge lines have to be created for its operation. Rather, the existing and tried and tested installation is used to supply fresh water or to drain bath water that has been drained or overflowed into the existing bathtub. A possible one Failure of the electro-pneumatic door seal would be obvious, ie its good function is monitored.
  • the use of the hip bath as requested therefore has a high level of reliability - particularly in terms of water technology. It has also proven to be advantageous that with the application of the hip bath, the movement sequence during bathing is simplified in such a way that it can also be handled independently by the physically handicapped and they are therefore no longer forced to deliver risky, motor-driven transfer maneuvers when bathing.
  • the hip bath insert according to the invention is suitable for being procured in large numbers by older people, in particular because of its advantages with regard to the cost price, maintenance and use in rented apartments. In this way, it can be widely distributed and thus enable the older population to be independent into old age - a social advantage that should not be underestimated.
  • the mobile hip bath insert 1 is designed as a tub body 3, which contains a watertight door 4, fittings 5 and an electropneumatic unit 6.
  • the tub body 3 is delimited at the front and rear by a front or rear tub body longitudinal side 7 or 8 and is closed at the bottom by a tub body foot part 9 and a seat arrangement 10 with a seat turntable 11.
  • the two sides of the tub body 7, 8 are below over their entire length formed as a tub body flanges 12, 13.
  • the existing bathtub 2 is a commercially available bathtub, as is normally installed in rental apartments. It has a front and a rear bathtub rim 14, 15 at the top.
  • 1b shows a cross section through the hip bath device, along the section line AA in FIG. 1a, when the hip bath insert 1 according to the invention is inserted into the existing bathtub 2 and supported on it.
  • the tub body foot part 9 is received without contact from the inside of the existing bathtub 2.
  • the bathtub body flanges 12, 13 are clearly visible as they come to rest on the existing bathtub 2 on the front and rear bathtub edges 14, 15 to support the hip bath insert 1.
  • 1c shows the hip bath device as it is formed by inserting the mobile hip bath insert 1 into the existing bathtub 2, in use by a physically disabled person 16 who is seated on the seat turntable 11 about the vertical axis 17 and is seated in the bathtub body with Foot part 9 freely hanging legs and a water level 18 that reaches shoulder height.
  • FIG. 2a A detailed illustration of the mobile hip bath insert 1 is given in FIG. 2, FIG. 2a showing its individual parts: namely the tub body 3, the watertight door 4, the fittings 5, and the electropneumatic unit 6 while in FIG. 2b - in an enlarged view Scale - the pneumatic rubber seal 19 is shown.
  • the tub body 3 is laterally delimited by tub body sides, namely by a front and a rear tub body long side 7, 8 both parallel to the longitudinal central axis 20, a foot and a head-side tub body transverse side 21, 22 both parallel to the transverse central axis 23 and downwards by a Tub body foot part 9 and a seat assembly 10 completed.
  • tub body 7, 8 The two sides of the tub body 7, 8 are formed on their undersides over their entire length as tub body flanges 12, 13 which run parallel to the longitudinal central axis 20 and approximately in the plane the seat assembly 10 lie.
  • the two bathtub body flanges 12, 13 come to rest on the corresponding bathtub edges 14, 15.
  • the front and rear bathtub edges 14, 15 are arranged approximately 50 to 60 cm above the bathroom floor 27. It is also the cheapest average height for a person.
  • the seat arrangement 10 ie the bathtub floor of the newly formed hip bath device, is at this ergonomically optimal height, so that there is no need for technical lifting devices can be.
  • the rear bathtub body long side 8 there is a recess 28 which serves as an overflow from the mobile hip bath insert 1 into the existing bathtub 2 and further enables narrow passages such as bathroom doors to be passed with the bathtub body 3.
  • the seat arrangement 10 contains a seat turntable 11 which can be rotated about the vertical axis 17.
  • the front side of the tub body 7 contains a watertight door 4 which is designed as a folding door 29, the door leaf 30 being used for the entry and exit with the hinge 31 about the horizontal axis of rotation 32 can be folded up and swung back and forth between a closed position Z and an open position O.
  • the door seal 33 provided between the door leaf 30 and the front side 7 of the tub body is a pneumatic rubber seal 19 which is secured in the closed position Z by the safety lock 34.
  • the foot-side bath body transverse side 22 contains fittings 5 which are connected to the fittings 36 of the existing bath tub 2 via flexible hoses 35. With the Electropneumatic unit 6, the pneumatic seal 19 is actuated. It is locked with the safety lock 34 against erroneous or improper operation.
  • FIG. 2b shows the pneumatic seal 19 of the watertight folding door 29 on an enlarged scale.
  • a sealing lip 38 which can be pneumatically actuated by the electropneumatic unit 6 between a non-sealing position N and a sealing position D. It thus ensures that the front side of the tub body 7 is sealed against water leakage.
  • the lower horizontal part of the door stop 37 is slightly raised with respect to the seat arrangement 10 with the seat turntable 11.
  • Fig. 3a for the case of a physically handicapped 16 of medium size or above
  • Fig. 3b for a physically handicapped 16 of smaller size.
  • the waterproof folding door 29 is folded up into the open position O. Since the door leaf 30 is supported by the gas spring 39, a muscle force of only about 5 Newtons is required for this, which can also be easily applied by older people.
  • the physically disabled 16 then sits on the seat turntable 11 in a seat position Q, outside the tub body 3 and parallel to the transverse central axis 23. He feels completely safe because he is comfortably supported on the bathroom floor 27 with both legs 40.
  • the next step is to get from the seating position Q into the interior of the tub body 3 in a comfortable and safe manner.
  • the seated person lifts his legs 40, for example one after the other, over the front edge of the bath tub 14 into the bath body foot part 9, turns from the sitting position Q and briefly goes through a transient sitting position T in which he is inclined to the tub body 3.
  • This rotary motion from the Sitting position Q is under constant control by the bather, who can hold himself at least with one hand, for example in the recess 28 in the rear side 8 of the bathtub body. He almost automatically rotates his body by 90 ° and arrives in a sitting position L within the tub body 3, parallel to its longitudinal central axis 20.
  • the water is first drained.
  • the door seal 33 is automatically relaxed and the safety lock 34 is released.
  • the folding door 29 can be opened upwards, which again requires only about 5 Newton muscle strength.
  • the patient can lift the legs over the open edge of the door opening and go to the side seat position Q on the seat turntable 11 to stand up next to the tub. Smaller people can use a stool 42 with a higher tub arrangement to achieve the optimal sitting height.
