Abstract

An arrangement for a patient lifting system, wherein the patient lifting system comprises a lifting device and a sling adapted to be coupled to the lifting device. The lifting device is during use of the lifting system adapted to lift the patient from a lowered to a raised position and said sling is adapted to be at least partly wrapped around the patient to be lifted. The arrangement of the present invention comprises at least one RFID-chip (1) provided in the sling, at least one RFID-reader (2) adapted to communicate with the RFID-chip and at least one sensing means (3) provided in the sling and adapted to communicate with the RFID-chip. The RFID-chip is adapted to contain, to store and to continuously be updated with new or updated information that is relevant to the use of said sling in the patient lifting system and further adapted to provide said information to said RFID-reader. In a preferred embodiment the sling is provided with thermal sensing means adapted to communicate with the RFID-chip and further adapted to sense when the slings is being washed.

Claims

1-10. -10. (canceled)

11. An arrangement for a patient lifting system having a lifting device and a sling, the lifting device being adapted to lift the patient from a lowered position to a raised position and the sling being adapted to be coupled to the lifting device and to assist the patient when lifted, the arrangement comprising:

at least one radio frequency identification (RFID) chip provided in the sling;

at least one RFID reader adapted to communicate with the at least one RFID chip; and

at least one sensor provided in the sling and adapted to communicate with the at least one RFID chip;

wherein the at least one RFID chip is adapted to contain, to store, and to be updated with information that is relevant to use of the sling and is further adapted to provide the information to the at least one RFID reader.

13. The arrangement of claim 11, wherein the at least one RFID reader is adapted to read and to update the information contained in the at least one RFID chip and is further adapted to provide the at least one RFID chip with new information and to provide the information to a user of the at least one RFID reader.

14. The arrangement of claim 11, wherein the at least one sensor comprises a thermal sensor adapted to detect when the sling has been washed, and upon detection that the sling has been washed, to provide the at least one RFID chip with information that the sling has been washed.

15. The arrangement of claim 11, wherein the at least one RFID reader is provided at the lifting device, is adapted to detect when the sling is used in the lifting system, and upon detection that the sling is used, to provide the at least one RFID chip with information that the sling has been used in the lifting system.

16. The arrangement of claim 15, wherein the at least one RFID reader is adapted to provide the at least one RFID chip with information about a date that the sling is used in the lifting system.

17. The arrangement of claim 15, wherein the lifting device is further provided with a lift preventer that is adapted to communicate with the at least one RFID reader and to automatically prevent the lifting device from being used to lift the patient if the at least one RFID reader is provided with information, from the at least one RFID chip in the sling intended to be used to lift the patient, that the sling should not be used.

18. The arrangement of claim 11, further comprising a readable database adapted to communicate with the at least one RFID reader and to contain and store information contained and stored in the at least RFID chip and/or the at least one RFID reader.

19. A sling for a patient lifting system having a lifting device and the sling, the lifting device being adapted to lift the patient from a lowered position to a raised position, the sling comprising:

a radio frequency identification (RFID) chip; and

a thermal sensor adapted to communicate with the RFID chip, to detect when the sling has been washed, and upon detection that the sling has been washed, to provide the RFID chip with information that the sling has been washed;

wherein the sling is adapted to be coupled to the lifting device and to assist the patient when lifted.

20. A lifting device for a patient lifting system having a sling and the lifting device, the sling being adapted to be coupled to the lifting device and to assist the patient when lifted, the lifting device comprising:

a radio frequency identification (RFID) reader; and

a lift preventer adapted to communicate with the RFID reader and to automatically prevent the lifting device from being used to lift a patient if the RFID reader is provided with information that the sling should not be used.
