Abstract
A device for detecting a hematoma or subcutaneous hemorrhage after a PCI, which includes a bandage provided with fastening elements for its placement at the PCI access site, and the use of a safety bandage for producing the same. In the device, the bandage includes a flexible and, in its longitudinal direction, non-elastic element connected to a strain sensor so arranged that the strain sensor, when the element after the placement of the bandage at the access site is subjected to a change in tension as a result of a hematoma or subcutaneous hemorrhage after the PCI, emits a signal that is indicative of the hematoma or hemorrhage.
Claims22
A PCI entry site pressure bandage device or safety bandage device provided with fastening means for the device's placement at a PCI entry site and adapted to detect a haematoma or subcutaneous haemorrhage at said PCI entry site, comprising:
- a pressure bandage part;
- and
- a detection means for detecting a haematoma or subcutaneous haemorrhage at the PCI entry site after a PCI,
- wherein the detection means includes an elongate, bending flexible and, in its longitudinal direction, substantially non-elastic element, to which element there is fastened a strain sensor arranged so that it emits a signal that is indicative of the haematoma or haemorrhage when the element, after the placement of the bandage over the entry site, is subjected to an increase in tension as a result of the occurrence of the haematoma or other swelling from subcutaneous haemorrhage after the PCI.
A production method for producing a PCI entry site pressure bandage device or safety bandage device adapted to detect a haematoma or subcutaneous haemorrhage at said PCI entry site, comprising:
- combining a PCI entry site pressure bandage part or safety bandage part and an electronic detection device to produce a device designed to both be able to be placed as a PCI entry site pressure bandage or safety bandage over a PCI entry site and to detect an increase in tension as a result of the occurrence of a haematoma or subcutaneous haemorrhage when the bandage is placed over the PCI entry site,
- wherein the detection device comprises a strain sensor attached to an elongate, flexible and, in its longitudinal direction, substantially non-elastic element.
