Therefore, there has been proposed a cooling pillow device that does not require a nurse to replace the cooling water or ice, unlike the water pillow and ice pillow used before.

However, in such a cooling pillow device, it is not necessary to go to see the cooling state of the pillow, but in the case of a child, the cooling pillow is disliked and unconsciously during sleep. It is necessary to go to the usage state of the cooling pillow device, and the effect of the turning angle which makes it unnecessary to look around and replace the cooling liquid is halved.

In general, when cooling the head of a patient with fever, it is comfortable for the patient to set the cooling temperature to a normal temperature when the head is moving left and right or the like. When the head does not move much, such as when sleeping, it is possible to cool only a certain part, so in such a case it is desirable to set the cooling temperature slightly higher than the normal temperature. .. Therefore, even with the cooling pillow device described above, in order to provide the patient with a comfortable rest and sleep environment, the nurse has to adjust the temperature of the cooling device according to the condition of the patient. was there.

【Example】

 FIG. 2 shows an embodiment of the cooling pillow device of the present invention, and the same parts as in FIG. 1 are designated by the same reference numerals. In FIG. 2, 1 is a cooling device, 2 is a cooling part of the cooling device 1, and a liquid heat medium 3 such as water to be cooled is enclosed therein. Reference numeral 4 denotes a pump for sending out the cooled liquid heat medium 3, and reference numeral 5 denotes a cooling pillow, where the liquid heat medium 3 is heat-exchanged. Reference numeral 6 is a hose for carrying the liquid heat medium 3 to the pillow portion 5, 7 is a hose for returning the liquid heat medium 3 warmed from the pillow portion 5 to the cooling device 1, and 8 is a patient's head. A pressure detector 9 measures the pressure of the liquid heat medium 3 in the cooling unit 2. Reference numeral 10 is an amplifier that amplifies the pressure signal detected by the pressure detection unit 9 as necessary. Reference numeral 11 is a relay, which is driven when the output of the amplifier 10 exceeds a predetermined value and activates its contact point 12. Reference numeral 13 is an audible signal generator such as a buzzer, 14 is a visible signal generator such as a lamp, and 15 is a power source.

In the cooling pillow device as shown in FIG. 2, as the cooling device 1, a freon gas type or an absorption type cooling device which operates quietly for burning city gas is used in a patient room or the like. Suitable for Although water is suitable for the liquid heat medium 3 for cooling, these troubles can be prevented by injecting a small amount of antifreeze liquid such as alcohol to prevent freezing. The pillow portion 5 and the hoses 6 and 7 are preferably made of a plastic material such as rubber.

To explain the operation, the pressure of the liquid heat medium 3 of the cooling unit 2 is different between when the head 8 of the patient is on the pillow 5 and when the head 5 is not placed. Is measured by the pressure detector 9. The pressure detection unit 9 of the liquid heat medium 3 is the same regardless of where it is measured by the principle of Pascal, but if the pressure detection unit is provided in the pillow portion 5, it will be an obstacle, so in this embodiment the cooling unit is used. It is provided in 2. The pressure detection unit 9 may be a strain gauge or a device in which a bellows is used to make a large mechanical change in pressure to directly operate the microswitch. When the head 8 of the patient is removed from the pillow 5, the pressure in the pillow 5 decreases, and this is detected by the pressure detector 9. This pressure change signal is amplified by the amplifier 10 as necessary to drive the relay 11. Let When the contact 12 of the relay 11 is closed, the buzzer 13 or the like is rung, and the lamp 14 or the like is turned on or blinks to notify that the patient's head has come off the pillow. In this embodiment, both the audible signal generator such as the buzzer 3 and the visible signal generator such as the lamp 14 are used for notification, but either one of the notification means may be used. In addition, it is preferable to monitor these notification methods at nurse centers. Also, although the signal transmission of the notification means is performed by wire, the wireless transmitter is operated by closing the contact point 12 of the relay 11, and the signal is received by a nurse center or the like, and the notification can be given by various notification means. it can.

Since the pressure change of the pillow part 5 occurs even when the patient rolls over or when he / she makes a slight movement, in order to prevent the notification means from operating against such a temporary pressure change. It is desirable to provide a timer device to notify only when the pressure change continues for a certain time or longer.

FIG. 3 shows another embodiment of the present invention, in which the same components as those shown in FIG. 2 are given the same reference numerals, and the cooling unit of the cooling device 1 is shown. The liquid heat medium 3 such as water cooled in 2 is circulated and supplied to the pillow 5 by the pump 4 via the hoses 6 and 7, and the head 8 of the patient is cooled. Describing new components, 16 is a CPU (central processing unit) that performs various processes according to the signal from the pressure detection unit 9, 11 is a relay driven by a control signal from the CPU 16, and 12 is its contact point. .. Reference numeral 17 denotes a timer device, which monitors a time interval between a pressure change occurring in the pillow portion 5 and a pressure change occurring next.

Next, the operation will be described. The CPU 16 constantly monitors the signal of the pressure detecting unit 9, and when the head 8 of the patient moves and the pressure detecting unit 9 detects a pressure change, the CPU 16 fetches the time from the timer unit 17. Since the time of this pressure change is taken in sequentially, the previous take-in time and the present take-in time are compared. Usually, when the patient is awake, the head is moved occasionally, and the time interval between pressure changes is short. Therefore, when the time interval at which the pressure change is detected is a predetermined time interval or less, for example, 15 minutes or less, the relay 11 is driven and the contact 12 is closed to, for example, the cooling temperature of the cooling device 1. Try to set the control from weak to strong. Moreover, when the patient does not move his / her head so much as when sleeping, the time interval of pressure change becomes long. Therefore, when the time interval at which the pressure change is detected is equal to or longer than a predetermined time, for example, when 15 minutes or more has elapsed, the contact 12 is released, and the cooling temperature control unit of the cooling device 1 is changed from strong to weak. Set to. Thus, when the movement of the patient's head 8 on the pillow 5 is frequent, that is, when the patient is awake, the liquid heating medium 3 of the cooling device 1 is kept at the normal temperature, When the movement of 8 is small, that is, when the patient is sleeping, the liquid heat medium 3 of the cooling device 1 can be kept slightly higher.

FIG. 4 is a flowchart of the embodiment shown in FIG. That is, the CPU 16 constantly monitors the signal from the pressure detection unit 9 as to whether or not there is a change in pressure. When there is a change, the time is fetched from the timer device, then the previous fetch time and the current fetch. The time difference from the time is compared with the preset time, for example, 15 minutes, and when 15 minutes have not passed, the relay 11 is driven (ON), and when 15 minutes has passed, the relay 11 is turned on. Is inactive (OFF). This operation is repeated below.
