Description

  The present invention relates to a turnover management system that manages a turnover state by detecting a change in posture within a predetermined time.

  As the population ages, the number of bedridden elderly and patient care / nursing scenes has increased rapidly in recent years. In such nursing and nursing settings, pressure ulcers that occur in bedridden elderly people and patients are an important issue. Pressure sores are bedridden cases in which bedridden elderly people and patients spend most of their day in the bed, compressing weight-bearing parts such as the waist, shoulders, and heels, causing blood circulation problems and causing damage to the skin. Say. This pressure ulcer begins to redden once it develops, and can be easily cured with a wound that easily deteriorates from an ulcer that reaches the dermis to a deep ulcer that reaches the fat layer, muscles, and bones.For example, removing necrotic tissue Such severe treatment is required. For this reason, the prevention of pressure ulcers has become a heavy responsibility for the facilities where care and nursing are carried out, and the burden on the nurses and caregivers at each facility is also heavy.

  On the other hand, as a measure for preventing pressure ulcers, for example, a bed slip prevention system that detects body movement of a patient and controls an air mat or the like according to the detected body movement has been proposed (see Patent Document 1). However, body pressure distribution devices such as pressureless beds and pressure displacement beds are too expensive for all patients to be used as subjects, and cannot completely prevent pressure ulcers. Moreover, although the effect which reduces pressure ulcer is recognized by performing nutritional supplements, such as protein, or diaper exchange, etc., pressure ulcer could not be prevented completely alone.

  For this reason, it is said that the most basic measure is to change the part to be compressed by weight by frequently and periodically changing the position by forcibly turning over. In general, the frequency of position change is performed every two hours. However, there is a great difference between individuals in the pressure of pressure ulcer, and there are cases where the position change is frequently required.

  Because of the situation described above, there is a current situation in which nurses and caregivers are forced to change positions regardless of night and day in each facility. In this case, the burden tends to increase particularly during night work, and for example, it is possible to forget to change the position, for example, when there is a sudden illness or a sudden change in the patient's condition. Moreover, even when the patient changes his / her posture due to turning over, a situation may occur in which the patient returns to the original posture through periodic posture exchange. Furthermore, in order to build a system that enables a fine-grained system that responds to individual differences, it is desirable to have a detailed understanding of the actual situation regarding posture exchange and turning over. However, there are practical limitations to constantly monitoring the actual situation manually. is there.

  The best mode for carrying out the present invention will be described below with reference to the drawings. The description of the present embodiment is an exemplification, and the configuration of the present invention is not limited to the following description.

  FIG. 1 is a schematic diagram showing an outline of a system configuration of a rollover management system according to an embodiment of the present invention. In this embodiment, a hospital is assumed as a facility, and a case where a nurse cares for a patient who is bedridden on a hospital bed is illustrated.

  As shown in the figure, the rolling management system 10 includes a receiving antenna 20, a measurement sensor 30, an ultrasonic microphone 40, and a measurement communication device 50 in one bed. Here, the measurement sensors 30 are attached to two or more parts that are points in confirming a change in the posture of the patient who is the subject. In the example shown in FIG. 1, it is installed on each of the left and right sides of the shoulder and waist. In this case, the measurement sensor 30 may be mounted on the patient's underwear. Further, the measurement sensor 30 is also attached to a site that becomes a point in confirming the presence or absence of the patient's manure. In this case, for example, the measurement sensor 30 may be mounted in a patient's diaper. Such a measurement sensor 30 has a limit in the transmission distance of information according to the radio wave transmitted from the receiving antenna 20. By utilizing such an action, the patient's bed leaving state is detected. Moreover, what is necessary is just to make the measurement communication apparatus 50 install for every hospital room or each bed, for example. In the example shown in FIG. 1, the measurement communication device 50 is installed for each bed via a hub 51 installed in each hospital room, and operates by being connected to a power source 52 near the bed. ing.

  Further, the measurement communication device 50 is connected to a host computer 60 installed at a center serving as a base for care and nursing, such as a nurse center, via a hub 51 and a LAN (Local Area Network) 53. May be. Thereby, a change in the posture of a bedridden elderly person or patient within a predetermined time by using the measurement sensor 30 that transmits information to and from the receiving antenna 20 through a radio wave transmitted from the receiving antenna 20 in a non-contact manner. By detecting various types of information such as the presence or absence of feces and urine and getting out of bed, the state of turning over can be managed. In addition, for example, at the nurse center, various detected information or instructions corresponding thereto are displayed on the host computer 60, an alarm is output according to the detected various information, or various reports or analyzes based on the detected various information. It is also possible to output information.

  Here, the system configuration of the turnover management system 10 will be specifically described. FIG. 2 is a block diagram showing a system configuration of the rollover management system according to the embodiment of the present invention.

  The receiving antenna 20 is installed below the frame constituting the bed that holds the body position, and transmits radio waves within a predetermined range and communicates information with a predetermined sensor via the radio waves in a non-contact manner. Send and receive. The receiving antenna 20 here also functions as an electromotive coil that generates electricity when energized from the measurement communication device 50 described later. Thereby, the receiving antenna 20 causes the measurement sensor 30 present on the bed, that is, the measurement sensor 30 attached to the patient sleeping on the bed, to receive information from the measurement sensor 30. Can do.

  The measurement sensor 30 is attached to at least two or more parts constituting the body position in order to specify the body position, and is provided with an identification number given to itself when at least receiving a radio wave transmitted from the receiving antenna 20 and generating power And an ultrasonic piezoelectric element that transmits ultrasonic waves due to the transmission of the identification number. Furthermore, a coil for non-contact communication is electrically connected to the chip microcomputer, and when the coil receives a radio wave emitted from the receiving antenna 20 and generates power, an identification number is transmitted using the power generation as a trigger. And ultrasonic waves are transmitted.

  In addition, activation information for transmitting information to the outside is set in advance in the measurement sensor 30, and the transmission timing of the identification number and the transmission timing of the ultrasonic wave are controlled based on the activation information. That's fine. For example, the activation information may include an internal timer in the chip microcomputer, and the internal timer may be set in advance with a time for turning on the power switch of the power source that operates the measurement sensor 30. Thereby, for example, when the measurement sensors 30 are mounted at a plurality of locations, information transmission from each measurement sensor 30 can be controlled with a time difference, so that interference can be prevented. As such a measurement sensor 30, for example, an IC tag having a size that does not burden the patient and that can be attached so as not to be easily removed is assumed. In the present embodiment, a sensor constituted by a 3 to 5 mm square chip microcomputer is assumed as the measurement sensor 30. Further, the measurement sensor 30 to be mounted to detect the presence or absence of feces and urine does not necessarily have to be able to transmit an ultrasonic wave, and the identification number is triggered by the electromotive force of the coil of the receiving antenna 20 as a trigger. As long as it can transmit.

  The ultrasonic microphone 40 receives the ultrasonic wave transmitted from the measurement sensor 30 and outputs ultrasonic information related to the ultrasonic wave. The ultrasonic microphone 40 is connected to a measurement communication device 50 (described later) via a predetermined line, converts the ultrasonic wave received from the measurement sensor 30 into ultrasonic information, and measures the communication device via the predetermined line. Output to 50. The ultrasound information here is information including at least the timing of receiving the ultrasound, that is, the reception time.

  The measurement communication device 50 is connected to the reception antenna 20 and the ultrasonic microphone 40, and based on the identification information including the ultrasonic information transmitted from the ultrasonic microphone 40 and the identification number transmitted from the reception antenna 20. The position information for detecting the change in the body position accompanying the time change of each measurement sensor 30 mounted on is measured. The identification information here is information including at least the identification number of the measurement sensor 30 and the reception time.

  Specifically, the measurement communication device 50 is installed at the site based on the time difference between the reception timing of the identification number received via the reception antenna 20 and the reception timing of the ultrasonic wave received via the ultrasonic microphone 40. The change in body position is detected from the change in position information of each part by calculating the distance between each measurement sensor 30 and the ultrasonic microphone 40 and measuring the position information of each part. Further, in the measurement communication device 50, the ultrasonic microphones 40 are provided at a plurality of locations with steps in the vertical direction so as to form a predetermined space, and the measurement sensors 30 are attached to each part existing in the space. In this case, three-dimensional changes in the body position detected at each part from the identification information regarding each measurement sensor 30 and the position information measured based on the ultrasonic waves transmitted in the space constituted by the plurality of ultrasonic microphones 40 are obtained. Detect as data. That is, as shown in FIG. 1, a change in the position of the patient is detected by detecting a change in the position of the four measurement sensors 30 mounted on the left and right sides of the shoulder and waist of the patient. In addition, for the detection of the position in three dimensions, for example, a general three-dimensional calculation technique capable of calculating a three-dimensional coordinate position based on distance data may be used. In this case, a three-dimensional calculation function capable of calculation as described above is introduced into the measurement communication device 50 or the host computer 60 so that the measurement communication device 50 or the host computer 60 can detect three-dimensional data. That's fine.

  In addition, the measurement communication device 50 controls the timing of energizing each receiving antenna 20 or the energizing interval when the receiving antenna 20 is installed on a plurality of beds. By such control, for example, when the receiving antenna 20 is installed on a plurality of beds provided in one hospital room, the measurement sensor existing on each bed is controlled by controlling the timing of energization of each receiving antenna 20. 30 can be each electromotive. In addition, by controlling the interval at which the receiving antenna 20 is energized, for example, it is possible to detect the position information that changes every time period by periodically starting the measurement sensor 30.

  Further, when a diaper incorporating the measurement sensor 30 is attached to the body position, the presence or absence of feces or urine is detected based on the state of data transmitted or transmitted from the measurement sensor 30. Furthermore, the receiving antenna 20 is installed in the whole lower part of the bed holding the body position, and the range of information that can be transmitted and received between the measuring sensor 30 and the receiving antenna 20 using the magnetic field generated from the receiving antenna 20 is set. By controlling, the bed leaving of the body position is detected based on the reception state of the identification information and the ultrasonic information. That is, in the example illustrated in FIG. 1, by limiting the communicable range to the bed, it is possible to detect the presence or absence of bed by using the fact that communication is interrupted when the patient leaves the bed.

  The host computer 60 manages each measurement communication device 50 in a unified manner when the measurement communication devices 50 are installed at a plurality of locations. Specifically, the presence or absence of a turn is managed by visually displaying a change in the body position detected by each measurement communication device 50 from at least one of the presence / absence of change, frequency, and time. Further, the host computer 60 is preset with conditions for managing the change in the posture of each patient, and whether or not the change in the posture detected by each measurement communication device 50 meets the condition. Judgment is made, and an instruction or alarm corresponding to the result is transmitted. The conditions set here are, for example, personal data that varies depending on the patient's constitution or body type. Thereby, for example, in the nurse center, since the state of each individual patient can be monitored in a unified manner, it is possible to take a fine response according to the state of each individual patient. Further, the host computer 60 issues a posture change instruction based on the patient's posture change state, a diaper replacement instruction upon detection of feces and urine, and an alarm upon detection of getting out of bed. This eliminates the need to constantly monitor the patient's condition, thereby reducing the labor burden of nurses and the like.

  Next, the control procedure concerning the rollover management system 10 will be described. FIG. 3 is a conceptual diagram illustrating the control procedure of the rollover management system according to the embodiment of the present invention. FIG. 4 is a time chart showing the control procedure of the rollover management system according to the embodiment of the present invention.

  In FIG. 3, the case where each energization with respect to the receiving antenna 20 installed for every bed with one measurement communication apparatus 50 is controlled is illustrated. Here, in the example shown in FIG. 3, for convenience of explanation, the receiving antenna 20 for each bed is indicated as I and II, respectively. The measurement sensors 30 existing on the reception antenna I are indicated as A1, B1, C1, D1, and E1, respectively, and the measurement sensors 30 existing on the reception antenna II are indicated as A2, B2, C2, D2, and E2, respectively. Here, the measurement sensors E1 and E2 do not have an internal timer, are sensors that are turned on at the same time as the electromotive force to the coil and transmit an identification number, and are mounted to detect the presence or absence of urine Has been. On the other hand, the other measurement sensors are sensors having at least an internal timer and a power source that activates the internal timer, and are mounted to detect the patient's posture and the presence or absence of bed. Hereinafter, the receiving antenna 20 will be referred to as receiving antenna I or II, and the measurement sensor 30 will be referred to as measurement sensors A1, B2,.

  As shown in FIG. 4, when the receiving antenna I is energized by energization from the measurement communication device 50, first, the measurement sensors A <b> 1 to E <b> 1 that are present on the bed on which the receiving antenna I is installed are sequentially sequential. Control is performed.

  Specifically, when the receiving antenna I is energized by energization from the measurement communication device 50, the coils built in the measurement sensors A1 to E1 are simultaneously energized. And the electromotive force with respect to a coil becomes a trigger and the power supply of the measurement sensor E1 which does not have an internal timer is turned on, and an identification number is transmitted simultaneously with the electromotive force. On the other hand, each of the measurement sensors A1 to D1 incorporating the internal timer is turned on at the timing when the time set in the internal timer has elapsed, transmits the identification number, and transmits an ultrasonic wave. In the example shown in FIG. 4, the time of the internal timer is set so that the power switch is turned on in the order of the measurement sensors A1-B1-C1-D1. The transmitted identification number and the transmitted ultrasonic wave are received via the receiving antenna I or the ultrasonic microphone 40 and accumulated in the measurement communication device 50 as identification information and ultrasonic information. By such control, a change in the posture of the patient sleeping on the bed on which the receiving antenna I is installed, the presence or absence of feces and urine, and the presence or absence of getting out of bed are detected.

  When the energization to the receiving antenna I is completed, the measurement communication device 50 energizes the receiving antenna II. As a result, when the receiving antenna II is energized, the measurement sensors A2 to E2 existing on the bed on which the receiving antenna II is installed are sequentially controlled, and the same control as the receiving antenna I is performed. Is called. In the example illustrated in FIG. 4, first, after the measurement sensor E2 is operated, the power switch is controlled to be turned on in the order of the measurement sensors A2-B2-C2-D2. Then, similarly to the receiving antenna I, a change in the position of the patient sleeping on the bed on which the receiving antenna II is installed, the presence or absence of feces and urine, and the presence or absence of getting out of bed are detected.

  By performing the control as described above alternately between the receiving antenna I and the receiving antenna II, it is easy to periodically change the posture, the presence or absence of sewage, and the presence or absence of getting out of the bed while preventing information interference. Can be detected automatically.

  In addition, it is desirable that energization of one receiving antenna is performed at intervals of 15 seconds to 1 minute after the end of control in the other receiving antennas. In the example illustrated in FIG. 4, the energization of the reception antenna I is performed after the energization of the reception antenna II is completed.

  Then, the measurement communication device 50 may store the accumulated identification information and ultrasonic information for a predetermined time, and transmit them to the host computer 60 at once after the predetermined time has elapsed. In the example shown in FIG. 4, identification information and ultrasonic information are accumulated for 5 to 10 minutes, and the information is transmitted to the host computer 60 at intervals of 5 to 10 minutes. Thereby, for example, when the measurement communication device 50 is installed for each hospital room, it is possible to efficiently manage information regarding the patient for each hospital room.

  As described above, in the present embodiment, the receiving antenna 20 is installed in the bed frame for the patient to sleep, and the identification number is transmitted to the part for detecting the patient's body position and the ultrasonic wave is transmitted. By mounting the measurement sensor 30 that can be used, it is possible to reliably detect and manage the state of turning over according to the individual bedridden patient. Furthermore, the presence / absence of a patient's bed can also be detected based on the presence / absence of information transmission from the measurement sensor 30. In addition, by attaching the measurement sensor 30 to a patient's diaper, it is possible to reliably detect the presence or absence of feces and urine that are likely to cause individual differences. Therefore, it is possible to perform various instructions such as forced posture change and diaper exchange, or alarms such as the occurrence of getting out of bed, based on the detection results of changes in the position, presence or absence of manure, and the presence or absence of getting out of bed for each patient. It is also possible to take meticulous responses while reliably managing the status of individual patients that change over time.

  As mentioned above, although one Embodiment of this invention was described, the fundamental structure of this invention is not limited to what was mentioned above.

  The rolling management system 10 described above is not limited to use in medical facilities and elderly care facilities. For example, the same system may be applied to home nursing homes, and in visiting care / nursing services, communication systems such as the Internet can be used to establish systems such as facilities and service companies. It is good also as a system which can manage flexibly from the remote place by making it cooperate, and the state of turning over of the patient who is bedridden. For example, as shown in FIG. 5, the LAN 53 corresponding to FIG. 3 is connected to the Internet, so that the management computer 70 corresponding to the above-described host computer 60 may be provided in the system 100 of the facility or service company. . In this case, the management computer 70 manages the condition of the patient at a remote location, so that the facility or service company can flexibly respond to the individual patient, such as dispatching a nurse as appropriate according to the condition of the patient. Can be taken.
