  In the case of the biological information monitoring system according to claim 1 of the present invention, a body temperature sensor that can be attached to the patient's ear and measures the body temperature in the vicinity of the inner ear, and a blood temperature that can be attached to the patient's earlobe and that measures the blood flow in the earlobe. It is easy to attach and remove both sensors, and the sensor can be moved freely without any obstacles, and the burden on the patient during measurement is small. There is an effect.

  In the case of the biological information monitoring system according to claim 2 of the present invention, on the premise of the configuration of claim 1, since it has a configuration having a urine volume sensor for measuring the load of the container for storing the urine discharged by the patient, In addition to the effect of the first aspect, the urine volume of the patient can be accurately measured, and the measurement accuracy is increased.

  In the case of the sensor attachment according to the third aspect of the present invention, since the body temperature sensor and the pulse sensor are provided in the insertion ear type main body, it is possible to attach to the patient's ear at a time. Easy to use.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram of a biological information monitoring system, FIG. 2 is an explanatory diagram for explaining how to use the system, FIG. 3 is a diagram showing a state where a sensor attachment used in the system is worn on the ear, 4 is a side view of the sensor attachment, and FIG. 5 is a partial external view showing the urine volume sensor of the system.

  The biological information monitoring system described here is a system for improving the efficiency of doctors and nurses in a hospital, and as shown in FIGS. 1 and 2, the body temperature, pulse, Measuring unit 100 that measures urine volume and other biological information, transmitting unit 200 that wirelessly transmits measurement data output from measuring unit 100, and receiving unit that receives and outputs measurement data transmitted from transmitting unit 200 300. The measuring unit 100 and the transmitting unit 200 are arranged in a hospital room, while the receiving unit 300 is arranged in a nurse's office.

  The measuring unit 100 can be attached to the ear β of the patient α (see FIG. 3) and measures the body temperature near the inner ear ε (see FIG. 3) and the earlobe γ of the patient α (see FIG. 3). A pulse sensor 120 that can be worn and measures the blood flow volume of the earlobe γ, a urine volume sensor 130 that measures the load of the storage bag 2 (container) that stores urine discharged by the patient α, and the like are provided. The other sensors are not shown.

  Here, an infrared radiation thermometer is used as the body temperature sensor 110, a light emitting LED is used as the pulse sensor 120, a transmission type optical sensor incorporating a light receiving LED, and a strain gauge is used as the urine volume sensor 130. Further, in order to easily and reliably attach the body temperature sensor 110 and the pulse sensor 120 to the ear β of the patient α, the sensor attachment 3 is used as shown in FIGS.

  The sensor attachment 3 includes an insertion ear type main body 31 that can be attached to the ear β of the patient α, an infrared radiation thermometer 32 that is a body temperature sensor 110 provided on the distal end side of the insertion ear type main body 31, and an outer ear attachment part. 31, a clip portion 33 that can be mounted on the patient's α earlobe γ from the front and back, a transmission type optical sensor 34 that is a pulse sensor 120 provided in the clip portion 33, and an insertion ear type And a signal line 35 taken out from the main body 31.

  When the center attachment 3 is used, it is not only securely attached to the ear α of the patient α, but also the infrared radiation thermometer 32 is positioned near the inner ear ε of the patient α (to the hypothalamus). Of the body surface through which the arteries pass is the position where the body temperature closest to the core temperature can be measured), and the ear lobe γ is sandwiched between the light emitting LED and the light receiving LED of the over-type light sensor 34. As a result, the body temperature and pulse of the patient α can be stably and accurately measured by the infrared radiation thermometer 32 and the transmission type optical sensor 34.

  The urine volume sensor 130 is provided in the box 2 attached to the bed 1, and is connected to a hook 131 for hooking the container 2 and a rear end side of the hook 131 as shown in FIG. It has a load detector 132 formed by bending a pipe, an iron base portion 133 fixed to the upper end of the load detector 132, and a strain gauge 134 attached to the load portion 132. That is, the load detecting body 132 is deformed and distorted according to the load of the containing bag 2, the magnitude of the distortion is measured by the strain gauge 134, and the urine amount discharged by the patient α is output.

  The transmission unit 200 is provided in the box 2, and digitally modulates the output signals of the body temperature sensor 110, the pulse sensor 120, the urine volume sensor 130, and other various sensors of the measurement unit 100 using a GFSK method, etc. It is configured to transmit a 2.4 GHz band radio wave called a “medical” band.

  In order to reduce the influence on other medical devices, the output is 1 mW and the transmission rate is 250 kbps. The transmission data includes not only measurement data of the measurement unit 100 but also data specifying a hospital room or the like.

  In addition, since the transmission part 200 is a small output, the transmission distance is 10-30 m, However, When the distance beyond it is required, what is necessary is just to prepare a radio repeater separately.

  The receiving unit 300 receives a radio wave transmitted from the transmitting unit 200 installed in each hospital room 1 and demodulates the radio wave and a demodulated signal output from the receiver 310 and receives measurement data from the measuring unit 100. It has a configuration including a personal computer 320 that performs display output in a predetermined format.

  The personal computer 320 constantly outputs and outputs the body temperature, pulse, urine volume and other biological information of the patient α in each room in a predetermined format on the display, and performs processing such as alarming when an abnormal value is detected. ing.

  In the biological information monitoring system configured as described above, when only the body temperature and the pulse need to be measured, it is only necessary to attach the center attachment 3 to the ear, and it can move freely, and the burden is extremely high. Small. In addition, since the system is very simple, it is possible to reduce the cost, which is of great significance for further popularization of the system.

  The biological information monitoring system according to the present invention is not limited to the above embodiment. For example, the measurement unit may be configured to measure biological information other than the patient's body temperature, pulse, and urine volume. The combination of sensors is arbitrary. The transmission unit is not particularly limited in the form of transmission frequency and transmission output. As for the body temperature sensor, as long as the body temperature sensor can be attached to the patient's ear and has a function of measuring the body temperature in the vicinity of the inner ear, the type of the body temperature sensor or the like may be used. The same applies to the pulse sensor. As long as the pulse sensor can be attached to the patient's earlobe and has a function of measuring the blood flow of the earlobe, its type is not limited, and a reflective optical sensor or the like may be used. Of course, both sensors may be mounted on the ear separately without using a center attachment.

  The center attachment which concerns on this invention is not limited to the said embodiment, For example, as long as it can be mounted | worn with a patient's ear about the insertion type | mold main-body part, the shape etc. will not be ask | required. As long as the clip portion is provided on the proximal end side of the outer ear mounting portion and can be mounted on the patient's earlobe from the front and back, the shape of the clip portion including the presence or absence of the hinge is not limited. As for the body temperature sensor and the pulse sensor, the types are not questioned as described above, and the design of the attachment location or the like may be changed as appropriate according to the type.
