Dual-cell cooling neckband for body protection}

The present invention relates to a dual-cell cooling neckband for body protection. Specifically, the dual-cell cooling neckband for body protection, when worn on a person's neck on a hot day, the neck area excluding the area where the person's carotid artery is located feels cool, At the same time, the temperature of the part that comes into contact with the human carotid artery is in a similar range to the human body temperature, so it relates to a dual-cell cooling neck band for body protection, which does not irritate the skin.

Recently, as global warming progresses rapidly, various adverse effects on the natural environment or human society have been reported. In particular, the increase in hot days due to the rise in temperature in the summer not only makes general social life difficult, but also makes people prone to heat stroke because their body temperature rises rapidly when doing physical labor or sports outdoors.

Especially in the hot summer months, the area around the neck becomes hot, and if you play sports for a long time, the body temperature rises and sweat flows around the neck. To cool the area around the neck, there were methods such as soaking a towel or handkerchief in water and wrapping it around the neck, but the towel was used. Alternatively, the method of soaking a handkerchief in water and wrapping it around the neck had the problem of not maintaining the cooling effect because the moisture evaporated immediately due to the hot sun or body temperature in the summer.

Therefore, as a way to solve the above problems, a variety of cooling neck bands have recently been developed that, when worn around the neck in a cool state on a hot day, gradually melt and absorb body heat to keep the body cool at a constant temperature. A patent is being applied for.

Patent Document 1 has a structure as shown in FIG. 1, wherein the cooling tube 1 includes a tube body 10 and a cover portion 20, a cooling medium is accommodated therein, and at least a portion is formed in a curved shape. A wearable cooling tube has been proposed that includes a polymer film layer and a fiber layer surrounding the polymer film layer and containing moisture, wherein the fiber layer is cooled by evaporation of the moisture.

And as a structure as shown in FIG. 2 in Patent Document 2, a tube extending in the longitudinal direction is formed through extrusion molding, and a contact portion 12 that is convex, that is, in contact with the neck, is formed through vacuum thermoforming. A neck ice cooling package is proposed in which the air flow portions 13 disposed therebetween are configured to repeat, and both ends 11 in the longitudinal direction are finished with high frequency.

In addition, in Patent Document 3, a pair of nipples 30 and a fixing ring 40 are installed on both ends 11 of a tube body 10 with longitudinal ends 11 facing each other so that it can be worn around the neck. A neck cooling tube capable of controlling the temperature of the structure has been proposed.

Meanwhile, recently, the proportion of carotid artery disease has been increasing due to changes in people's eating habits, and among ischemic cerebrovascular diseases caused by blocked blood vessels, such as high blood pressure and stroke, carotid artery disease accounts for about 30%, and carotid artery disease accounts for about 30% of carotid artery disease. The most common cause is atherosclerosis, which develops in the same way that debris gets stuck in old pipes and narrows the inside of the pipe, and is deeply related to adult diseases such as high blood pressure, hyperlipidemia, and diabetes, stress, and especially smoking.

In this way, when a cooling neck band as suggested in Patent Documents 1 to 3 is worn on a person's neck to avoid the extreme heat in the hottest summer weather, the cold cooling neck band suddenly sends blood from the heart to the brain and the brain operates smoothly. When it comes into contact with the carotid artery, which is a blood vessel that supplies energy to function properly and is located symmetrically on both sides of the neck, the vascular passage of the carotid artery narrows, causing carotid artery stenosis, which may be detrimental to health.

Therefore, the present invention was completed by developing a dual-cell cooling neck band for body protection according to the present invention in order to prevent the occurrence of the above problems in advance.

Detailed descriptions and drawings are omitted, and only technical configurations related to the present invention are briefly shown or described.

As shown in Figures 3 to 7, the dual-cell cooling neckband 100 for body protection according to a preferred embodiment of the present invention has a first accommodation space for accommodating the first cooling medium inside surrounded by the shell 10. (S1) is formed, and the tube body 20 is arranged symmetrically so that both ends are adjacent to each other and has a ring-shaped structure to surround the human neck; And when the tube body 20 is worn on a person's neck. The tube body 20 is characterized in that it is composed of a dual cell 30 in which a second receiving space S2 is formed at a position in contact with the position of the neck through which the human carotid artery passes, thereby accommodating the second cooling medium.

In the present invention, 'dual cell' refers to both the left cell (S2a) and the right cell (S2b) located inside the tube body (20) in contact with the carotid artery symmetrically located on both sides of the human neck. it means.

The material of the outer shell 10 is preferably thermoplastic polyurethane (TPU), a material that is harmless to the human body. In addition, the dual cell partition wall 40 that separates the first accommodating space S1 inside the tube body 20 and the second accommodating space S2 of the dual cell 30 is also preferably made of polyurethane resin (TPU).

Meanwhile, the melting point of the first cooling medium accommodated in the first receiving space (S1) inside the tube body 20 is the melting point of the second cooling medium accommodated inside the dual cell, which is the second receiving space (S2). It is characterized by a lower melting point temperature than the melting point temperature.

Therefore, as shown in Figure 7, even if the dual-cell cooling neck band 100 for protecting the cold body is worn on a person's neck on a hot day, the tube body 20 is in contact with the neck area excluding the portion where the person's carotid artery is located. The temperature of the first receiving space (S1) is lower than the human body temperature, so the person feels cool, but the temperature of the second receiving space (S2) of the dual cell (30), which is the part in contact with the human carotid artery, is lower than the human body temperature. Since the temperature is in a similar range, the skin is not irritated, which has the effect of preventing the occurrence of carotid artery stenosis in advance by preventing the constriction of the carotid artery's vascular passage.

The first cooling medium and the second cooling medium filled in the first accommodation space (S1) and the second accommodation space (S2) are phase change materials (PCM), and their types are as follows.

It is a material that has the characteristic of accumulating positive thermal energy or releasing the stored thermal energy. To cool a neck band with phase change material (PCM) applied, place it in the freezer of a refrigerator for about 10 minutes, or soak it in cool tap water for about 30 minutes. When left under a cool air conditioner for about 30 minutes, the phase change material (PCM) contained within the neck band cools to a solid state below the melting point temperature as shown in [Table 1] below.

In addition, when a neck band in which the phase change material (PCM) has solidified and cooled is worn around a person's neck, the melting point of the phase change material (PCM) is affected by the temperature of hot summer weather along with the person's body temperature (Table 1). When the temperature exceeds the melting point as described in , the solidified phase change material (PCM) melts and you feel cool.

The neck band containing the phase change material (PCM) is accommodated in the second receiving space (S2) of the dual cell 30 and sealed by high-frequency adhesive, and the first phase change material (PCM) is accommodated in the second receiving space (S2) of the dual cell 30. ) is accommodated in the first receiving space (S1) of the tube body 20 and is sealed by high-frequency adhesion. As described above, the phase change material (PCM) is repeatedly frozen and melted due to temperature changes. Repeated reuse becomes possible.
