A METHOD AND DEVICE FOR EVALUATION OF THE RISK OF DECUBITUS DEVELOPMENT IN A PATIENT IN A HOSPITAL BED

摘要

The method of evaluation of the risk of decubitus development in a patient in a hospital bed comprises continuous monitoring of the position of the patient's gravity centre. The current position of the patient's gravity centre is compared to the previous position of the patient's gravity centre and if the established difference is higher than the preset limit value, this change of the gravity centre position is evaluated as a substantial movement while the dependence of the number of substantial movements of the patient on time is determined and if the number of substantial movements of the patient drops below the preset limit, the movement activity is evaluated as insufficient and information about the risk of decubitus development is issued. The device for evaluation of the risk of decubitus development in a patient in a hospital bed comprises at least three force sensors (3) that can be installed under the loading area (1) of a hospital bed and the outputs of the force sensors (3) are connected to the input on the block (4) for calculation of the position of the patient's gravity centre. The output of the block (4) for calculation of the position of the patient's gravity centre is connected to the first input of the block (5) for determination of the movement activity of the patient. The block (6) for setting the boundary conditions is connected to the other input of the block (5) for determination of the movement activity of the patient. The output of the block (5) for determination of the patient's movement activity is connected to a display unit (7).
