Description

  The present invention relates to a body cooling / heating device for cooling / heating a body using a Peltier element. In particular, the body cooling / heating device of the present invention applies a plurality of heat transfer plates to the skin (for example, around the neck) in the vicinity of a thick blood vessel passing near the body surface via a flexible hinge. Thus, the present invention relates to a body cooling / heating device that lowers (increases) the temperature of blood. The present invention also relates to a body cooling / heating device that is easy to work without being stiff, even if it is attached to the periphery of the neck for a long time.

  The air-conditioning clothes using a Peltier device are described in Unexamined-Japanese-Patent No. 2004-263325, for example. A clothing temperature variable unit and a temperature variable clothing including the unit are described in, for example, Japanese Patent Application Laid-Open No. 2008-031581. The conventional air-conditioning clothing has a problem that it is difficult to bring the cooling surface (heat generation surface) of the Peltier element into close contact with the body, and effective air-conditioning cannot be performed.

  In addition, the air-conditioning clothing is not directly applied to the skin, and there is a problem that energy efficiency is poor when the underwear is used. Moreover, even if the Peltier device can be brought into close contact with the body, the air-conditioning clothing does not have thick blood vessels in the back or abdomen, and only partially lowers (increases) the skin surface temperature. It was difficult to control body temperature in a short time.

  The entire circumference of the neck can instantly obtain a cool feeling without impairing the function of cooling the vicinity of a thick blood vessel. It is said that there is a switch of the arteriovenous anastomosis blood vessel (AVA) that controls the body temperature on the back side of the neck (see trivia reader NHK for Gatten 7 “I found a switch that promotes cold blood circulation”). Heating and cooling the back of the neck can open and close the arteriovenous anastomosis (AVA) and enhance the cooling and heating effect by blood circulation.

  Furthermore, the body air conditioning apparatus described in Japanese Patent Application No. 2009-187644 uses a Peltier element. FIG. 4 is a view for explaining a body cooling / heating device using a conventional Peltier element. In FIG. 4, a thermally conductive metal sheet 41 having a cooling surface (heat generating surface) with good thermal conductivity, at least part of which is formed from a Peltier element 42, is a thick blood vessel that passes close to the surface of the neck 49, for example, It touches the skin around the neck.

  The heat generating surfaces (cooling surfaces) of the pair of Peltier elements 42 are a circulation part (flexible pipe 44) for circulating water or coolant, and a heat exchange part for cooling or heating water or coolant supplied to the circulation part. 43, a power supply unit (battery) 47 that supplies power to the Peltier element 42, and a cooling / control unit 45. The power supply unit 47 and the cooling / control unit 45 are connected by a power cord 46 and, at the same time, attached to a band 48 provided on the waist of the body, for example.

  Thick blood vessels that pass close to the body surface include, for example, the carotid artery, the subclavian vein blood vessel, the subclavian artery blood vessel, and other arteries or veins in the arm, the crotch, and the like. The heat conductive metal sheet 41 is provided with a heat generating surface (cooling surface) of the Peltier element 42 on the opposite side of the surface contacting the body surface. The cooling water or coolant is cooled or warmed by the heat exchange unit 43 during circulation. The power supply unit 47 supplies power to the control of the cooling / control unit 45 in order to exert the Peltier effect in the Peltier element 42.

  FIG. 5A is a plan view for explaining the structure of a heat conductive metal sheet, a Peltier element, and a heat exchanging part attached around the neck, and FIG. 5B is a sectional view thereof. 5 (a) and 5 (b), the first water channel 51-1, the second water channel 51-2, and the third water channel 51-3, which are heat exchange units, are the first flexible tube 52-1. The second flexible tube 52-2, the third flexible tube 52-3, and the fourth flexible tube 52-4 are connected as illustrated.

  Since the body cooling / heating device is carried around the body, it is important that the weight is light. As the thickness of the heat conductive metal sheet increases, heat conduction improves. However, when the thickness exceeds 0.3 mm, the heat conductive metal sheet lacks flexibility and needs to be shaped according to the shape of the neck. However, there is a drawback that the cross-sectional shape of the neck varies from person to person and requires customization. A graphite sheet is known as a material having flexibility and good thermal conductivity. The graphite sheet is brittle and easily peeled off, and in particular has a low mechanical strength in the thickness direction.

  Further, since the graphite sheet is brittle and easily peeled off, there is a problem that when it is structured to be bonded to a Peltier element, the mechanical bonding strength is insufficient and the inside breaks. Further, the graphite sheet needs to be in close contact with the heat conductive metal sheet, but there is a problem that an air layer exists due to the concavo-convex portion and the heat conductivity is deteriorated.

  Since the heat conductive metal sheet is in contact with the neck, it is not only difficult to move the neck back and forth or turn, but it also has a problem that the shoulder stiffens when worn for a long time. Further, the body cooling / heating device has a problem in flexibility when it is worn on the neck when a thick heat conductive metal sheet is used. Furthermore, the body cooling / heating device has a problem that the portion of the heat conductive metal sheet is bulky and takes a place to store.

  Further, the reservoir tank needs to prevent leakage of the cooling water or coolant. Furthermore, since the reservoir tank is large and bulky, it cannot be attached to the body as a body cooling / heating device. When bubbles enter the reservoir tank, the flow velocity becomes faster than the buoyancy of the bubbles, and there is a problem that the bubbles enter the pump side with the flow velocity. In order to prevent the above problem, the conventional reserve tank is provided with a shielding plate for blocking bubbles near the outlet. However, the shielding plate has a limited effect, and a large casing is necessary to completely kill the flow velocity and meander.

  In order to solve the problems as described above, the present invention has a configuration in which a connection part of a plurality of thermally conductive metal sheets can be moved in the vertical direction, the horizontal direction, and the twisting direction. An object of the present invention is to provide a body cooling / heating device using a Peltier element that improves the mobility in the surroundings and can perform work comfortably even when worn for a long time.

In addition to simple air-conditioning systems, the present invention is intended to quickly increase body temperature when it is desired to lower the body temperature quickly, such as heat stroke, or when the body temperature drastically decreases due to drowning or is likely to cause frostbite in winter mountains. It is an object of the present invention to provide a body cooling / heating device using a Peltier element that is convenient for other medical needs.

In particular, when the body cooling / heating device is mounted around the neck, the range of freedom of movement has expanded, so that a person working inside a steelworks, freezer compartment, etc. can easily perform comfortable work even for a long time. It became so.

  According to the present invention, since the body temperature can be raised or lowered via blood by directly contacting or wearing the skin in the vicinity of a thick blood vessel passing through a place close to the body surface, the body temperature can be increased or decreased.

  In the above experiment, even when a heat transfer plate is used, heat can be exchanged at the carotid artery at about 10w to 20w at one location. If it is cooled further, the temperature becomes too low and there is a risk of pain and frostbite. Accompanied by. Furthermore, for cooling, the cooling capacity can be increased by increasing the number of Peltier elements and cooling a plurality of portions where thick blood vessels other than the carotid artery, such as the subclavian, armpit, and base of the foot, are close to the skin surface.
