Abstract

<P>PROBLEM TO BE SOLVED: To provide a system which solves the problem that a bedridden patient or an elderly falls from a bed accidentally at intervals of patrol of a nurse or a male nurse in a hospital or a nursing home, and neither the nurse nor the male nurse can know the state that a condition is further worsened by falling, and monitors the patient's falling from the bed. <P>SOLUTION: The system is constituted so that a bed 1 is covered with a thin piezo-electric sheet 2, and when a patient 3 lies on the piezo-electric sheet 2 feeble voltage is generated from the piezo-electric sheet 2, and this feeble voltage is amplified by an output circuit 4 which incorporates an amplifier and generates output, and the output from this output circuit 4 is displayed in an indicator 6 connected via a communication cable 5, and this indicator 6 is installed in a central control center, etc. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a patient confirmation apparatus for confirming whether a bedridden inpatient in a hospital or a nursing home is on a bed.

  Traditionally, in hospitals and nursing homes, several nurses and nurses regularly manage the condition of many bedridden inpatients and bedridden elderly people, especially at night. Since the management is performed by a small number of nurses and nurses, the time interval for patrol is long and the patient's condition cannot be confirmed frequently.

Therefore, in such conventional hospitals and nursing homes, the patient falls from the bed between patrols and the patient and the nurse do not know the fall of the patient until the next patrol, which worsens the condition. There has been a need for a system that monitors the patient's fall from the bed.
Special application

  The problem to be solved is that in a hospital or nursing home, a bedridden patient or elderly person accidentally falls from the bed and makes the condition worse by this fall. This is a point that nurses and nurses cannot know.

  In the present invention, a thin piezoelectric sheet is laid on the bed, and the weak voltage from the piezoelectric sheet generated by the patient sleeping on the piezoelectric sheet is amplified and output by the output circuit. The presence / absence of voltage is displayed or sounded by a sound generator to confirm whether or not the patient is present on the piezoelectric sheet laid on the bed.

  The patient confirmation apparatus according to the present invention confirms whether there is a patient on the bed, so that when the patient falls from the bed in the course of patrol or when the nurse or nurse is not near the patient, the piezoelectric sheet By displaying that no weak voltage is generated or sounding with a sound generator, it is possible to report the patient's fall to the central management center and respond to the patient's fall for a short time There are advantages.

  FIG. 1 is a configuration diagram of a patient confirmation apparatus according to an embodiment of the present invention. When a thin piezoelectric sheet 2 is laid on a bed 1 and a patient 3 is lying on the piezoelectric sheet 2, the piezoelectric sheet 2 is weak. Since a voltage is generated, this weak voltage is amplified by an output circuit 4 incorporating an amplifier to generate an output, and the output from the output circuit 4 is displayed on a display 6 connected via a communication cable 5, The display 6 is configured to be installed in a central management center or the like.

  In the patient confirmation apparatus of the present embodiment configured as described above, a weak voltage is generated when the patient 3 is lying on the piezoelectric sheet 2, so the weak voltage is amplified by the output circuit 4 and amplified. The output is output to a display device 6 connected to the communication cable 5, and this display device 6 is installed in a central management center or a nurse room, so that the patient 3 can display the piezoelectric on the bed 1 on the display of the display device 6. It can be confirmed that the patient 3 is on the sheet. Here, when the patient 3 falls from the bed 2, no weak voltage is generated from the piezoelectric sheet 2, so the output of the output circuit 4 becomes 0 and is not displayed on the display 6. Therefore, it is possible to know that the patient has fallen from the bed, and if this fall is known, the nurse or nurse can go to the patient who has fallen in a short time and take action. Gets worse It is possible to prevent.

  In the above embodiment, an example in which the display 6 is provided in the central management center has been described. However, instead of providing a sound generator on the display 6 and displaying it on the display 6, the sound is output by a sound generator such as a buzzer. By taking it out, it is possible to immediately know that the patient has fallen from the bed, and to take a shorter time.

It is a block diagram of the patient confirmation apparatus of one Example of this invention.
