In the case of lifts in which the position of the free ends of the strap are accurately known during lifting, it is also possible for the sensors to be designed as position sensors.
Description
- The present invention relates to a raising device comprising a lifting device and a carrying strap, which is connected to the lifting device, for holding the person to be raised, said lifting device comprising an electric lifting member which is controlled by a control unit. A raising device of this type is generally known in the prior art. As an example, reference is made to European application EP 0782430 A. It should be understood that other raising devices, and in particular other lifting devices, also lie within the scope of the present invention. One example which may be mentioned is a ceiling lift in which cables or the like extend downwards from the ceiling and can be coupled to a carrying strap so as to move a patient.
- The carrying strap may be a single strap which is wrapped, for example, beneath the armpits or beneath the buttocks of the patient. It is also possible for the carrying strap to be of multiple design, i.e. to have, for example, four free ends, so that the patient can be moved in a horizontal position.
- The term carrying strap is also understood as meaning carrying jackets and other structures. The only important factor is that the carrying strap be slightly flexible and be arranged around the patient and has to be connected to the lifting device in order for it to be possible to carry out lifting. It should also be understood that where the text refers to lifting, this is also intended to encompass lowering of the patient.
- In practice, it has been found that as a result of increased pressure of work there is an increasing risk that the connection between carrying strap and lifting device will not be perfect. In general, this is not a problem, since the carrying strap becomes detached before the actual lifting takes place and the person remains in the original position.
- However, if the carrying strap does become detached during lifting, there are risks to the health of the patient and liability risks for the institution concerned and/or the operating staff.
- To resolve this problem, the prior art proposes improved connecting methods between carrying strap and, for example, the lifting arm of a lifting device. For example, it has been proposed to attach a pin with a collar to the lifting arm and to provide the carrying strap with a keyhole-shaped opening at its end. Under load, the narrowed part of the keyhole-shaped opening will rest on the pin section.
- However, it has been found that there is still a risk of accidents. This applies both to straps with two ends and to straps with more ends, such as three or four ends.
- DE 4447393 C discloses a crane hook provided with a sensor which checks whether or not a load has been correctly positioned. If positioning is incorrect, lifting is impossible. Raising heavy loads using large cranes as described in the above publication cannot be compared to raising patients.
- The object of the invention is to provide a safe raising device which eliminates risks of an imperfect connection and the resultant consequences.
- In a raising device as described above, this object is achieved in that there are sensor means which detect that the carrying strap has been correctly attached to the lifting device and which are connected to said control unit such that, in the event of incomplete or incorrect attachment, at least the lifting movement by the said lifting member is blocked.
- In general, the lifting devices operate electrically with the aid of some kind of control. Consideration may be given to remote controls, control panels and the like. According to the invention, it is proposed for this control to be influenced in such a manner that, if the connection between carrying strap and lifting device is not perfect, lifting is impossible. The above-described sensor means may comprise any structure known in the prior art. The most simple structure is a (micro)switch, for example arranged in the lifting arm of the lifting device, which detects the presence of the relevant coupling part of the strap. The relevant part of the coupling is only present at this location if the coupling is perfect.
- It is also possible to provide electrical contact or to construct an electric circuit which is only closed if all the connections to the lifting device satisfy the demands imposed. The sensors may comprise all mechanical, electrical or electronic, magnetic or optical sensors.
- The connection between lifting device and carrying strap may be any connection which is known in the prior art, but preference is given to a rapid-action coupling with male and female parts, the carrying strap being provided with the male part. In this case, the demands imposed on the design of the coupling are less high. This is because if connection is not perfect, according to the invention it will be impossible for lifting to be carried out. The risk of accidents is in principle reduced to zero.
- According to an advantageous embodiment of the invention, there is also a presence sensor which detects the presence of a patient. This sensor may, for example, be designed as a weight sensor and detects whether the strap has been subjected to a load. Naturally, the presence sensor may also be designed differently and may function using spring structures, light beams or any other structure which is conceivable in the
- If the strap is free of load, the lifting member, such as an electric motor, can be readily operated, since there is then no risk of accidents. As a result, it is possible to use the device even though the strap is not perfectly connected. This may be of importance when moving the device towards a patient in order subsequently to move the patient.
- The invention will be explained in more detail below with reference to an exemplary embodiment illustrated in the drawing, in which:
- Fig. 1 diagrammatically depicts a raising device according to the invention;
- Fig. 2 diagrammatically depicts the electrical connections according to the invention;
- Fig. 3 diagrammatically depicts one end of a strap.
- Fig. 1 shows a raising device according to the invention. Details of this device can be found in European application 96904387.6, which is incorporated by reference. For the present invention, it is only important to understand that the device comprises a frame 2 which can be moved on
wheels 15. The other end of the frame is provided with a lifting-arm assembly, comprising an auxiliary arm 3 and a lifting arm 4. These arms can be operated if appropriate independently of one another, in a manner which is not shown in more detail. The main lifting motor is denoted by 10. It is actuated viaconsole 16, which is connected tocontrol unit 19. The power supply is denoted by 18. A remote control can be provided, if appropriate.Kneerests 12 are also arranged on the frame. In the vicinity of the free end of the lifting arm 4 there are catches 8 designed to interact with the free ends of astrap 13.Strap 13 can be uncoupled from the free ends of lifting arm 4. - The coupling between
strap 13 and the end of the lifting arm 4 is not shown in detail. For the invention, it is only important that there besensors 7 which register that the coupling has been made perfectly and the signal from these sensors is fed to controlunit 19. A weight sensor, which records the load on the lifting-arm assembly 3, 4, is denoted by 11. - The device described above operates as follows. If a patient is to be moved, for example, from a sitting position to a standing position, the
lifting device 1 is moved towards the patient who is sitting, for example, on a chair. One side of thestrap 13 is uncoupled from lifting arm 4 and is arranged beneath the arm pits and behind the back of the shoulders of the patient. Then, the free end ofstrap 13 is connected to lifting arm 4 once again. If this connection is not perfect, there is a risk that the connection will become detached during lifting and that the patient will fall once the chair has been removed, which may lead to injuries or other problems. - However, according to the invention the
motor 10 can only be operated bycontrol unit 19 after bothsensors 7 have detected that the connection of the two free ends ofstrap 13 to the free end of the lifting arm 4 is perfect. Only then does controlunit 19 enable operation by means ofconsole 16. - The only exception to this is if there is no load on the
strap 13 and therefore on the arm assembly 3, 4. This is recorded byweight sensor 10. If the load on the lifting-arm assembly, and more particularly on the free end of lifting arm 4, is, for example, less than 10 kg, this is detected bysensor 11, and in that case thesensors 7 are not effectively connected to the control unit, i.e. themotor 10 can be operated. - It will be understood that such weight sensors may also be integrated in the coupling between the free end of
strap 13 and the free end of the lifting arm 4. As an alternative to weight sensors, it is also possible to use other presence sensors which can be used to record the presence of a patient. - Fig. 3 shows one end of a
strap 13 which is illustrated in part. It can be seen from this figure that that part which is to be fitted into the receiving part of lifting arm 4 is pin-shaped, and this part is denoted by 20. It is provided with a mushroom-shapedprojection 21, by means of which it can be locked in the receiving part of lifting arm 4. Locking of this nature can be released, for example, with the aid of a push-button. The use of a pin-shapedend 20 which is to be arranged in a receiving part accommodated in or attached to the lifting arm 4 has the advantage that the end of thelever 13 can only be fitted in one position, unlike in the prior art, in which use is made of eyelets attached to the strap, which have to engage over pins arranged at the ends of lifting arm 4. In practice, it has been found that it is particularly easy for incorrect attachment to take place, and this may lead to accidents and injuries. - It will be understood that the design of the end of the raising strap which is shown here can be used for any type of raising strap and is not used exclusively for the structure according to the present invention. However, with the structure shown in Fig. 3 it is easy to operate an electric switch.
- As described above, the structure described here works with all kinds of lifting devices. This also applies to lifting devices in which, for example, balance brackets are used, connected between the lifting arm and the carrying strap. As indicated above, the device can also be used for ceiling lifts and structures of this kind. It is only important that the invention offers protection against lifting or lowering a patient in the loaded state when the connection between the carrying strap which carries a patient in whatever way and the lifting arm, balance bracket or other part of the lifting device is not perfect. In the case of lifts in which the position of the free ends of the strap are accurately known during lifting, it is also possible for the sensors to be designed as position sensors.
- These and further variants lie within the scope of the present invention as described in the appended claims.
