Description

  The present invention relates to a warmer worn on the extremities, and more particularly to a warmer effective for improving hypertension.

  As a cause of high blood pressure, when blood vessels contract, it becomes difficult for blood to flow, and the force that the heart pushes out blood is strongly applied to the blood vessel wall, increasing blood pressure. Further, when the cardiac output increases and the blood volume becomes excessive, the force applied to the blood vessel wall increases, and the blood pressure increases. Therefore, as one of the effective measures for improving hypertension, it is said that an antihypertensive effect can be obtained by appropriate aerobic exercise.

  The human body tries to maintain the body temperature by collecting blood at the center of the body, especially when it is cold, especially when the center of the body where important organs gather is kept at a constant temperature of around 37 degrees. . For this reason, blood hardly spreads to the limbs away from the center of the body, which is the terminal, and the force that the heart pushes out the blood is strongly applied to the blood vessel wall, increasing blood pressure. Therefore, if aerobic exercise is performed, blood reaches the limbs and hypertension is improved. However, aerobic exercise must be careful not to overload the body, it is difficult to adjust, and it is a risk for the elderly.

  On the other hand, in addition to aerobic, a hypotensive effect can also be obtained by warming the limbs and dilating peripheral blood vessels. What is known about heat insulation of limbs is that it has a bottom part that abuts the sole of the foot and an upper that covers the instep and the heel, both of which are made of an airtight material on the outside. A warming footwear having an outer member, an inner member made of an aluminum sheet on the inner side, and a heat insulating material provided between the inner member and the outer member, a front portion contacting the front of the hand, and the back of the hand A front part and a back part, both of the front part and the back part are an outer member formed of an airtight material on the outer side, an inner member whose inner side is an aluminum sheet, and the inner member and the outer side. There is an upper limb bag for heat insulation having a heat insulating material provided between the members (see, for example, Patent Document 1).

  However, in order to keep warm for the purpose of improving high blood pressure, it is effective to wear for a long time, preferably while sleeping. In that respect, conventionally known warming footwear and upper limb bags are mainly used for cold protection and are highly airtight, uncomfortable for long-time use, and warped when worn throughout the night. It is hard to sleep and I cannot rest.

  In view of the above, an object of the present invention is to provide a warmer having a good touch and a high warming effect.

  In order to solve the above-mentioned problems, the present invention is a heat retaining device for covering a person's limbs with four bags, each of which includes an upper limb bag in which an upper limb is accommodated and a lower limb bag in which a lower limb is accommodated. There are two types, both of which are formed by sewing a knit fabric knitted with hygroscopic exothermic fiber yarn and silk yarn.

  Here, the upper limb bag may be long enough to accommodate at least the forearm and the hand part beyond the elbow. The lower limb bag may be long enough to accommodate each part of the lower leg and foot beyond the knee.

  In addition, it has a supporter that is formed by knitting a knit fabric knitted with hygroscopic heat-generating fiber yarn and silk yarn and knitting it into a cylindrical shape. It has dimensions that can cover the temples and the nape of the neck. Wearing such a supporter at the time of sleeping warms the acupoints of the neck and the periphery of both eyes and promotes the activation of the parasympathetic nerve, thereby making it easier to go to sleep smoothly.

  The yarn may have a silk ratio in the range of 80% to 20%, and the remaining 20% to 80% may be hygroscopic exothermic fibers. Furthermore, elasticity can be obtained by adding a rubber thread to the thread.

  The heat-retaining device according to the present invention has a heat-generating function by moisture-absorbing heat-generating fibers and a silk feel that is excellent in moisture retention, moisture absorption, and breathability, so that it does not cause discomfort to the user even if it touches the skin for a long time. High heat retention is obtained. Therefore, when the limbs are warmed, the peripheral blood vessels of the limbs are spread and hypertension is improved.

The explanatory view of the heat insulator concerning the present invention is shown. An example of the upper limb bag of the heat insulating device of FIG. 1 is shown. An example of the leg bag of the heat retention apparatus of FIG. 1 is shown. Explanatory drawing of the transition of each day in 60 days of the highest value of the blood pressure after waking up, wearing the heat insulator which concerns on this invention at bedtime is shown. The external view of the supporter used for a heat insulator is shown. The explanatory view of the usage form of a supporter is shown.

  Embodiments of the present invention will be specifically described below with reference to the drawings. FIG. 1 shows a heat insulator 1 according to the present invention, which is composed of four bags 2 in which limbs can be accommodated. There are two types of the bag body 2, an upper limb bag 3 and a lower limb bag 4. The upper limb bag 3 can accommodate the upper arm, the forearm and the hand, and the lower limb bag 4 can accommodate the thigh, the lower leg and the foot. The upper limb bag 3 and the lower limb bag 4 are produced by sewing a knit fabric obtained by knitting hygroscopic heat-generating fiber yarns and silk yarns that absorb moisture and generate heat. The mixing ratio of the moisture-absorbing exothermic fiber and silk at this time is such that the ratio of silk is in the range of 80% to 20%, and the remaining 20% to 80% is the hygroscopic exothermic fiber.

  As shown in FIG. 2, the upper limb bag 3 may be long enough to accommodate the forearm and hand part of the upper limb beyond the elbow, and the lower limb bag 4 is lower than the knee of the lower limb as shown in FIG. 3. The length may be such that the lower leg and foot parts can be accommodated. Thus, it is easier to bend the joint when the elbows and knees are exposed than the bag body 2, and it is suitable for long-time wearing. In addition, even if the bag body 2 is long enough to fit the elbows and knees, the user may fold it back according to their preference.

  Further, the bottom portion of the bag body 2 where the hands and feet can be accommodated may be a bifurcated type that separates and stores only the thumb or a type that separates and stores five fingers. FIG. 2 shows an example of an upper limb bag 3 in which only the thumb is stored separately, and FIG. 3 illustrates an example of the lower limb bag 4 in which five fingers are stored separately.

  Moisture-absorbing exothermic fibers use the property that heat is generated when a substance adsorbs moisture (adsorption heat). Specifically, moisture is adsorbed by hydroxyl groups on the fiber surface to convert kinetic energy into thermal energy. Fiber. There are various types of heat-generating materials such as acrylic materials and materials using cupra, but materials with light weight and stretch properties are the best.

  Silk is a material that has rich moisture absorption, breathability, and heat retention in addition to good texture.

  When a bag 2 made by knitting a hygroscopic exothermic fiber yarn and silk yarn having such characteristics is sewn on the upper limb and the lower limb, the hygroscopic exothermic fiber absorbs sweat and generates heat, thereby providing a heat retaining effect. Rise. Furthermore, since silk is hygroscopic and breathable, it feels good, and comfort is maintained at the same time as keeping warm, so there is no discomfort even when worn while sleeping. And the bag body 2 produced by sewing a knit fabric knitted with hygroscopic exothermic fiber yarns and silk yarns in this way is easy to move because it is thinner than one using a resin heat insulating material.

  By maintaining the temperature of at least the forearm and the hand by the upper limb bag 3, the blood flow to the hand is increased and the temperature is effectively maintained. The lower leg bag 4 keeps at least the lower leg and legs warm, so the calf region of the lower leg is said to be the second heart, and it warms to act as a pump that returns the blood accumulated in the lower body by gravity to the heart. This improves the blood flow throughout the body. In this case, the blood flow is improved by improving the blood flow in the deep part of the calf, but the calf has a low surface temperature and takes time to warm up. Therefore, it is more effective if the lower limb bag 4 is worn for a long time while sleeping.

  As described above, in order to effectively extract the characteristics of the hygroscopic exothermic fiber and silk, the optimal mixing ratio of the hygroscopic exothermic fiber and silk is preferably 60% for silk and 40% for hygroscopic exothermic fiber. And in order to improve the elasticity and the adhesiveness to skin when the bag body 2 is worn, a rubber thread can be further added. However, excessive contractility results in overtightening of the site and worsens blood flow. Further, in order to keep warm, the bag body 2 needs to have an air layer with a space between the skin, and the bag body 2 is shifted by setting the mixing ratio of the rubber thread from 2% to 3%. There is no loss and appropriate tightening force is expressed. Therefore, when the rubber yarn is contained, it is appropriate that the rubber yarn is 2% to 3% of the above with respect to 60% of the silk, and the remainder is the moisture-absorbing exothermic fiber.

  FIG. 4 shows the transition of the maximum blood pressure value measured every day for 60 days after 30 minutes have passed since waking up while wearing the upper limb bag 3 and the lower limb bag 4 in both hands and both feet. In the figure, the first day systolic blood pressure value is 158 mmHg, and the 60th day systolic blood pressure value is 134 mmHg. During this period, there are several days that exceed the first day 158 mmHg, and the fluctuation range for each day is large. It can be seen that the maximum blood pressure value is decreasing and stable. Therefore, it has been confirmed from this result that wearing the heat retaining device 1 according to the present invention and sleeping, the limbs are warmed during sleep, the peripheral blood vessels are expanded, and the blood pressure is lowered.

  In addition to keeping the limbs warm, it is more effective to keep the eyes, ears, temples and nape of the neck warm. In addition to the upper limb bag 3 and the lower limb bag 4, the heat retaining device 1 of another embodiment sews a knitted fabric knitted with hygroscopic exothermic fiber yarns and silk yarns as shown in FIG. A supporter 5 knitted into a cylindrical shape is provided. The diameter W and the height L of the cylinder of the supporter 5 are set so as to cover a person's head and cover the eyes, both ears, the temple, and the nape of the neck. In the supporter 5 as well, the optimal mixing ratio between the moisture-absorbing exothermic fibers and silk is optimally 60% silk and 40% hygroscopic exothermic fibers. When the rubber yarn is included, the rubber yarn is added to 60% silk. It is preferable to use 2% to 3% of the fiber and the remaining moisture-absorbing exothermic fiber.

  As shown in FIG. 6, the supporter 5 having the above-described structure is such that when the head is covered so as to cover the eyes, both ears, the temple, and the neck nape of the person, both eyes and the periphery of the temple and the ear are warmed. Relaxes and improves blood circulation. There are acupuncture points around the eyes such as Sanbuchi, Ryoko Hitomi, and Reimei, and there are acupuncture points on the ears that are used to adjust the sympathetic and parasympathetic nerves of the autonomic nerves. They are densely packed, and warming these acupressures promotes blood flow and relaxes, and also recovers tired eyes and eyestrain.

  When the supporter 5 is put on the head and goes to bed, the parasympathetic nerve is dominant and leads to a good sleep. And since it uses hygroscopic heat-generating fibers and silk as a material, the fabric is thin, lightweight, and stretchable, so it can be worn comfortably without disturbing bedtime.

  According to the heat insulating device 1 having the above configuration, the upper limb bag 3 and the lower limb bag 4 that are produced by sewing a knit fabric knitted with hygroscopic heat-generating fiber yarn and silk yarn are worn away from the center of the body. It has the effect of warming the limbs. As a result, blood reaches the hand, the peripheral blood vessels expand, resistance to blood flow decreases, and high blood pressure is improved.
