Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a portable memo writing tool in a dark place, which integrates the function of a flashlight and a writing unit with lighting.

[0002]

[Problems to be solved by the device]

 In the past, there was no flashlight with this kind of writing part, and it was necessary to prepare a stand for placing memo paper, a normal pen and a light separately, or to use a thick and heavy pen with a light as a pen. It was inconvenient.

In order to solve this problem, the applicant of the present invention has proposed a flashlight with a memo function in which a front illumination function and a writing portion illumination function are integrated and an improvement thereof (Japanese Patent Application No. 4-75444). , Jpn. Pat. Appln. No. 5-35658 and Jpn. Pat. Appl. It is an object of the present invention to propose the addition of a function for facilitating pulse measurement and a radio function to the flashlight with a memo function.

That is, in the case of pulse measurement, the nurse usually counts the pulse for 15 seconds and converts it into the value for 1 minute. Stopwatches and timers are convenient for measuring arbitrary time, but in the case of stopwatches, the watch must be constantly watched, and in the case of timers, it is necessary to set 15 seconds each time. There was a drawback that the operation was troublesome. Thus, it has been desired to make nursing care in the dark bed at midnight as convenient as possible.

[0005] Also, conventionally, a product in which a radio is incorporated into a flashlight has been released, but none has an illuminated writing part. Therefore, for example, in the event of a power outage at night or due to storms and floods, a portable radio was the only source of information, and it was necessary to illuminate the area with a flashlight in order to make a note of its contents.

[0006]

[Means for solving problems]

 In order to achieve the above object, the first object of the present invention is to integrate a front illumination mechanism, a writing unit, and a writing unit illumination mechanism so that the set includes a one-touch 15-second timer. It is a thing. A second object is to have a detachable pulse measuring mechanism. The third purpose is to have a thin radio inside.

In order to achieve the first object, the timer is preferable in terms of downsizing and high accuracy, and it is desirable that the timer can be confirmed by sound when the timer is pushed and when the time has elapsed. Alternatively, a lighting display such as an LED may be used alone or in combination. The timer may be incorporated into a small liquid crystal digital timepiece, and the liquid crystal digital timepiece may be incorporated into a flashlight with a memo function.

In order to achieve the second object, it is preferable that the sensor section is independent of the main body and can be connected to the main body by a plug-in method at the time of measurement. The sensor may use either an acoustic method or an optical method.

Since the pulse signal fluctuates at the measurement site, it is preferable to provide a function of displaying the pulse detection signal with an LED or the like on the sensor unit or the main body side for confirmation of pulse detection. For example, if the received pulse signal is displayed on the LED, it can be seen that the pulse signal is detected by seeing if the LED blinks at a fixed cycle, thus improving the reliability of pulse measurement. To do.

In order to achieve the third object, the thin type radio is most suitable for the present invention as a portable type flashlight with a memo function for the purpose of implementation.

【Example】

 Hereinafter, the present invention will be described in detail with reference to embodiments with reference to the drawings. FIG. 1 is a circuit diagram of a 15-second timer according to an embodiment for achieving the first object of the present invention. In FIG. 1, 1 is a timer IC, 2 is an LED, 3 is a push switch, and 4 is a buzzer. The timer IC1 used NE555 which is a general-purpose timer on the market. The LED 2, buzzer 4, resistor and capacitor are connected as shown in the figure. The buzzer used had a self-excited oscillation circuit. Although an arbitrary timer time can be set by changing the resistance value R and the capacitor C value, in this circuit, the timer time T is T = 1.1RC. In the case of the 15 second timer of this embodiment, R = 1.36M and C = 10 μF.

As described above, according to the present invention, a 15-second timer can be manufactured with a small number of parts, which is suitable for miniaturization and is convenient for being incorporated in a flashlight with a memo function.

According to the present circuit, when the push switch 3 is turned on, the LED 2 is turned on for 15 seconds when the timer is started, and the buzzer sounds when 15 seconds have elapsed. Therefore, the pulse rate can be obtained by counting the pulse rate while the LED is on and multiplying the value by four.

Further, since the timer circuit of FIG. 1 produces an error of 0.01% or less even when the ambient temperature changes by 10 degrees, the pulse measurement of the patient can be performed with high accuracy.

To use.

As is well known, hemoglobin in blood has a light absorption property in the near infrared light region. Therefore, for example, LED light having a wavelength of 780 nm is irradiated through the skin to a blood vessel to scatter light scattered from the blood vessel. When received by a photodetector such as a photodiode, scattered light periodically changes according to the flow of blood, that is, the pulse. Therefore, by disposing the LED and the photodetector close to each other and bringing them into contact with the skin as in the present invention, it is possible to reliably detect the scattered light of the near-infrared light irradiated on the blood vessel, A pulse meter can be configured.

A pulse rate monitor to which this principle is applied has already been put to practical use. For example, there are products incorporated in digital watches. With this product, the sensor unit and the data processing / display unit were integrated, so it was not designed to measure the pulse of another person. Therefore, it was not possible for a nurse to measure a patient's pulse using this type of pulse meter on the market.

In the present invention, the sensor unit is detachable from the main body of the flashlight with a memo function, and since it is a finger sack type, any person can surely measure the pulse, and the writing unit illumination can be used even in a dark place. With this, the pulse rate can be confirmed and the patient's condition such as the pulse rate can be recorded on the spot.
