Description

  The present invention relates to a bed using muscle strength measurement, its selection, and an appropriate arrangement method. When the human body is in a supine state, the muscle strength expression and effect generated by the muscles against external force are used and applied to the bed related products, especially the bed mattress, and the bed mattress suitable for the user is provided. The user can select and appropriately arrange the bed mattress that meets the demand of the user.

  It has been demonstrated in medicine that the hardness of a bed or bed mattress has a significant impact on the quality of sleep. Thus, how to select an appropriate bed has that much need and importance. In particular, users suffering from spinal pain or related illnesses may suffer further damage if they lie on an inappropriate bed for a long time. People usually spend about 1/3 of a day sleeping and resting. In other words, about one third of your life may be lying on your bed. However, there seems to be no time-saving way to systematically and economically decide how to choose a bed mattress or bed that suits the individual's needs. .

  The vast majority of consumers buy a bed mattress based on their hardness preference and the touch of the material when lying on the bed mattress. Often the mattress is not found, and consumers who suffer from spinal pain may even buy a bed mattress based on the idea that the harder the better. Typically, after a consumer purchases a particular bed mattress, after a certain period of use, the consumer recognizes that the initially selected bed mattress is not suitable for him. However, if you notice that the quality of your sleep is not good or improved, and you feel uncomfortable with your spine, back, or lower back (for example, low back pain due to long-term badness of your spine), choose a bed mattress again. In this case, not only does it waste time and does not meet economic benefits, but the newly purchased bed mattress may still not be a bed mattress suitable for itself.

  Specifically, a bed mattress suitable for oneself in general refers to a bed mattress that a user can support to make it accurate and comfortable in the supine state. The physical characteristics related to the definition of accurate and comfortable include the alignment of the spine, the contact pressure or body weight distribution between the body and the bed, the body surface temperature of the contact portion and the bed's sweat absorption. Among them, the alignment and contact pressure of the spinal column causes stiffness and injury to the muscles and ligaments in the lower back of the human body, and the degree to which it is most concerned. The alignment of the spinal column and the contact pressure when a normal person with a specific weight lies on the bed mattress depends on the influence of the person's weight. That is, there is no single bed mattress or bed that can be adapted or applied to different users. In addition, similar or identical users or consumers may have significant differences in muscle tissue, body fat, blood vessel distribution, and spinal arc. In addition, the influence of the same bed mattress on each person is not constant, muscles and blood vessels are improperly pressed, and the user cannot apply force due to improper curvature of the spine, or inappropriate Studies have also shown that the bed mattress or bed's suitability and comfort are naturally reduced when stress is applied.

  FIG. 1 shows a side view of a normal human spine 20 '. A normal human spine 20 'has a total of 33 vertebrae, of which 7 cervical vertebrae C1-C7, 12 thoracic vertebrae T1-T12, 5 lumbar vertebrae L1-L5, 5 sacral vertebrae S1-S5 and 4 tail vertebrae V1-V4 are included. The degree of curvature shown in the side view indicates the degree of arc that should be when the normal person's spine 20 'is upright. When a normal person is standing in an accurate and good posture when standing upright, a single vertical line extending from top to bottom can pass from the side to the earlobe, shoulders, the top of the hipbone, the back of the knee, and the front of the talus. . In the supine state, the cervical and lumbar vertebrae of the human body are almost opposite to the degree of arc when the spine is upright, away from the bed or bed mattress, and the thoracic and sacral vertebrae are almost opposite to the degree of arc when the spine is upright and approach the bed. ing. This means that when lying on a flat surface, the human cervical and lumbar vertebrae float in the air, which requires good support to stretch the entire spine and relax the muscles. It can be avoided or reduced. Keep the spine aligned with the above-mentioned upright curvature even when the user's spine is in a supine position so that the spine is stretched, not subject to inappropriate pressure, muscles relax, and nerve transmission is relatively good A bed or bed mattress that can be supported accurately and comfortably is a bed mattress suitable for the user or consumer.

  It is one method of verifying whether the spine is maintaining the accurate curvature when standing upright in the supine state using measurement using a device or fluoroscopy. However, this method is not suitable for economic efficiency, is time consuming and labor intensive, and has many limitations such as inconvenience of facilities and places. Therefore, how to examine the curvature of the spine without using X-rays or other similar fluoroscopic devices or visual fluoroscopy methods, and effectively overcome the above-mentioned defects, even when the spine is in a supine position The issue is how to ensure that the curve or degree of arcing is ensured. In addition, as described above, a bed mattress suitable for a user is provided according to different body shapes, weights, spine arc degrees and muscle structures of a plurality of users, and the user's spine is stretched when standing upright in a supine state. It is another problem to make such a state, relax muscles, and make nerve transmission relatively good. It is another challenge to provide a bed mattress that is suitable for the unspecified consumer in a manner that effectively saves time and is in economic benefit (ie, selection and proper placement).

  The foregoing is a summary of the present invention and is not intended to limit the scope of the present invention. Since the technical contents mentioned here can be implemented by different methods and embodiments, any changes or other modified embodiments do not violate the scope of the present invention. Hereinafter, more preferred embodiments of the present plan will be described in detail.

  The bed mattress obtained using the muscular strength measurement of the present invention and its selection and appropriate placement methods include a variety of different embodiments and can be achieved by different implementations. In one embodiment, it refers to a bed mattress tailored for the user using muscle strength measurement, and in another embodiment, refers to a bed mattress manufactured using muscle strength measurement, and yet another. One embodiment refers to the selection and proper placement of bed mattresses using muscle strength measurements. The bed mattress obtained by using the above-described muscle strength measurement can maintain a substantially accurate degree of curvature when the user's spine is in a supine state substantially upright. This stretches the user's spine, avoids improper pressure, relaxes the muscles, prevents improper pressure on the blood vessels, and makes nerve transmission relatively good. And the occurrence of injury can be avoided or reduced.

  The bed mattress 10 shown in FIG. 2 is a side view of the embodiment, and includes a bed surface 12 and a bed bottom surface 14.When the user lies on the bed mattress 10 and contacts the bed surface 12, the bed mattress 10 The user's spine 20 can be supported accurately and comfortably. That is, when the vertebral column 20 in the supine position has almost the same arc as the vertebral column 20 ′ in the upright position compared to the curvature of the vertebral column 20 ′ in the upright position shown in FIG. It can be considered a bed mattress that is “suitable” for the user or consumer. That is, the bed mattress 10 has a hardness H suitable for the user.

  Next, how to provide a bed mattress 10 suitable for the user, the user's spine stretches when lying on the back, does not receive improper pressure, the muscles can relax, and the nerve transmission is relatively good One of the objects that the present invention wants to achieve is whether it is possible to avoid or reduce the occurrence of stiffness and injury, and whether the equipment used by the prior art or similar fluoroscopy technology is not required. is there. Using a muscle strength measurement to provide a bed mattress suitable for the user or consumer will be described in detail as follows. Among these are custom made bed mattresses, manufactured bed mattresses, and methods of using muscle strength measurements to select and properly place the bed mattress for the user or consumer.

  In an embodiment of a bed mattress 10 tailored for a user utilizing muscle strength measurements in the present invention, the bed mattress is substantially accurate when the user's spine 20 is in a supine position, with the spine upright. The bed mattress 10 capable of maintaining a high degree of curvature and having a hardness includes a composite material structure 15, a bed surface 12 and a bed bottom surface 14 of at least one material, Determining whether the user has discomfort in the spinal column, calculating the user's body mass index (BMI), and measuring the user's lower limb strength, of which the use In measuring the strength of the user's lower limb, an external force is applied to the user's lower limb, the user applies a force to act against the external force, and the force applied by the user is substantially at least the force of the external force. Balance with It includes adjusting the hardness of the bed mattress until it can be taken.

  First, referring to FIG. 3 showing that the ability of the lower limbs of the user P is measured, when the user P lies on the bed mattress 10, at least one leg is bent as shown in the figure, and the state is almost 90 degrees. It is preferable to do. Next, an external force F is applied to the thigh of the foot, and the direction thereof is substantially parallel to the horizontal direction when the user is supine as shown by the arrow A in the figure, and the sole of the user's foot The force of external force F is applied in the direction of. In an embodiment, the external force F is preferably continued for at least 5 seconds. Thereafter, the user P applies a force F ′ in a direction opposite to the external force A, and in the embodiment, in order to try to be substantially balanced with the external force F or exceed the external force F. In addition, it is preferable that the user P applies F ′ force with the quadriceps muscles of the foot.

  Further, in another embodiment of the present invention, the user P applies F 'force in the opposite direction of the external force F, and maintains the angle of approximately 90 degrees that the user presented by bending the foot. Thus, it is preferable to represent or judge that F ′ can be substantially balanced with at least the external force F. Regardless of the method and means for applying the force F, the force F applied by the human force (for example, the tester applies the external force), the pressing force generated by the machine, or the force applied using the muscle strength measuring device is included. It can be understood that both belong to the scope of the present invention. In addition, it is not necessary for the foot part of the user P to bend approximately 90 degrees, and only the state where the foot is raised may be used.

  In the embodiment of the bed mattress 10 that is custom-made for the user P using the muscle strength measurement, it is preferable that a determination as to whether the user P has discomfort in the spinal column is included. The presence of discomfort of the spinal column includes a case where a situation different from that of a normal person occurs due to a spinal bay, a congenital or acquired spinal disease, a spinal injury, or the like. However, even if user P has discomfort in the spinal column, it does not affect the performance of normal muscle strength measurement, or the body-especially the muscles of the legs and legs, nerves and blood vessels undergo muscle strength measurement. If possible, the lower limb strength measurement can be performed.

  As mentioned above, when a bed mattress suitable for the user can accurately and comfortably support the user in the supine state, the user's spine can maintain a substantially upright curvature, so It stretches and is not subject to inappropriate pressure, and the muscles are relaxed and nerve transmission is relatively good. The measurement of human muscle strength takes advantage of this advantage, when the spine and muscles stretch, blood vessels are not subject to improper compression, and neurotransmission is advantageous for contraction and release of human strength, said representation of muscle strength of the human body Can be measured. For example, an external force F having a force equal to a weight of 2 kg is applied to the thigh muscle of the user P, and the user applies the force F ′ lightly or normally so that the force is at least approximately equal to or greater than the force of the external force F. If it can be counteracted, the user's spine and muscles can stretch when lying on the bed mattress, and neurotransmission is beneficial to the contraction and release of human strength Represents that.

  The lightly or normally applied force here means that the user can perform general affairs with his normal physical ability and physical strength, for example, a force of about 2 kg in the same way It may be a comparison value such as the degree of difficulty felt or received by the body when. Usually, when the human muscles are restricted, blood vessels are compressed, or nerves cannot be transmitted relatively smoothly, the difficulty level when applying force is affected. The strength described here may be any magnitude or strength, and can be understood to be not limited to the above numerical values.

In an embodiment of a bed mattress 10 tailored for a user utilizing muscle strength measurements in the present invention, the tailored method can also include calculating the user's body mass index. The physique index refers to Body Mass Index (BMI), and the definition of the index is as follows.
BMI = weight (kg) / height2 (m2)
Of these, weight refers to weight (unit: kilogram) and height refers to height (unit: meters).

  For example, according to widely accepted standards, if a person's body mass index is 18.5-25, he has the best weight for height, and if the body mass index is less than 18.5, If you have a lean weight and an index above 25, you have a weight that is too heavy. The calculation result of the physique index can include using the height and weight measured by the user as reference data. It can be understood that the numerical value of the body weight can be used alone as reference data in this example. Therefore, in another embodiment of the present invention, it may include only measuring the weight of the user as reference data. In yet another embodiment, the weight and / or height directly notified by the user may be used as reference data. In addition, it can be understood that it is possible to calculate the physique index in the embodiments of the present invention when this stage or step is performed or the order with other technical means is not limited. it can. For example, in one embodiment, the physique index calculation step can be performed before the lower limb strength measurement, and in another embodiment, the step can be performed after the lower limb strength measurement.

  In an embodiment of the bed mattress that is custom-made for a user using the muscle strength measurement according to the present invention, the composite material structure therein includes at least two kinds of materials having different hardnesses. The bed surface adjacent to the side different from the material structure and the bed bottom surface have different relative hardnesses. 4A to 4C are three-dimensional views of different embodiments of the bed mattresses 10A, 10B, and 10C obtained by using the muscle strength measurement in the present invention. In the embodiment, the bed mattresses 10A, 10B, 10C include composite material structures 15A, 15B, 15C having at least one material, bed surfaces 12A, 12B, 12C and bed bottom surfaces 14A, 14B, 14C, of which The composite material structures 15A, 15B, 15C are provided between the bed surfaces 12A, 12B, 12C and the bed bottom surfaces 14A, 14B, 14C. First, as in the embodiment of the bed mattress 10A of the present invention shown in FIG. 4A, the composite material structure 15A can include one or more kinds of materials M1 and M2 having different hardnesses. For example, M1 may be a relatively low hardness H1 or a relatively soft foam (eg, memory foam, viscoelastic foam, etc.) and M2 may be a relatively high hardness H2 (eg, sponge, coconut yarn, etc.) It may be. Since these materials explain the difference in relative hardness between the materials, the present invention is not limited to the above materials.

  Since the composite material structure 15A in one embodiment is provided with a relatively soft material M1 on a relatively hard material M2, the bed surface 12A is adjacent to the relatively soft material M1, and the bed bottom surface 14A is Adjacent to the relatively hard material M2. That is, the bed surface 12A of the bed mattress 10A is softer than the bed bottom surface 14A, and is used for the user P to lie and use. Next, as shown in FIG. 4B, another embodiment of the bed mattress 10B of the present invention may include a bed surface 12B, a bed bottom surface 14B, and at least one composite material structure 15B therebetween. In one embodiment, the composite material structure 15B can also be composed of one or more materials such as M1 and M2 having different hardnesses H1 and H2 as described above. The difference is that in this embodiment, the composite material structure 15B is provided with a relatively hard material M2 on a relatively soft material M1, so that the bed surface 12B is adjacent to the relatively hard material M2 and the bed bottom surface 14B is Adjacent to the relatively soft material M1.

  As shown in FIG. 4C, in one embodiment of the present invention, the bed mattress 10C includes a bed surface 12C, a bed bottom surface 14C, and at least one composite material structure 15C, and the composite material structure 15C includes at least two types. Including M1, M2, and M3. For example, in the embodiment, the hardness H3 of M3 is smaller than the hardness H1 of M1. That is, H2> H1> H3. Therefore, in the embodiment of the bed mattress 10C, since the bed surface 12C is adjacent to the material M3, it becomes M2, M1, M3 in order from top to bottom, and the hardness ranges from soft to hard (H3, H1, H2). For example, the added M3 may be a relatively soft flexible foam, the material M1 may be a hard foam, and M2 may be a sponge or coconut thread. In another embodiment, the bed mattress 10C may have the material M2 adjacent to the bed surface 12C, so that the order of the material from the top to the bottom of the composite material structure 15C is M2, M1, M3 and its hardness Ranges from hard to soft (H2, H1, H3).

  It can be understood that the purpose of the bed mattress embodiments described herein is to describe the technical features that it can include and is not limited to these embodiments. For example, material M3 can also be provided under M2 or between materials M1 and M2. In addition, the composite material structure of the bed mattress is such that M1 and M2 are substantially the same material or the same hardness, or that M1, M2 and M3 are all substantially the same material or the same hardness. As such, it can have only one composite material structure, both of which are within the scope of the present invention. The composite material structure may further include three or more different materials, such as further including materials M4, M5, etc., which are also within the scope of the present invention, and the hardness of materials M4, M5, etc. (eg, H4, H5 Etc.) may be larger or smaller than H3.

  In an embodiment in which a user P lies on the bed mattress 10, the external force F is applied to the lower limb of the user P when the user P lies on at least one of 10A, 10B, and 10C, and the user uses the force F 'Is added to counteract the external force, thereby measuring the strength of the lower limbs and understanding whether the provided bed mattress 10 is a bed mattress suitable for the user P. Also, as described above, if the bed mattress 10 is a bed mattress suitable for the user P, the force amount F ′ applied by the user is substantially balanced with at least the force amount F of the external force. be able to. More preferably, it is balanced with or exceeds the external force to the extent that the user normally applies force. When the amount of force F ′ applied by the user P cannot be substantially balanced with at least the amount of force F of the external force, or when the user normally applies force, the external force is balanced, If not, use by adjusting the hardness of the bed mattress 10 until the user P can apply force F 'in muscle strength measurement and can at least balance with the external force F substantially Bed mattress suitable for the elderly. Of these, the adjustment of the hardness of the bed mattress 10 will be further described with reference to the embodiments of the bed mattresses 10A to 10C. Details are as follows.

  In an embodiment of the bed mattress that is custom-made for a user using the muscle strength measurement according to the present invention, the adjustment of the hardness of the bed mattress may include increasing or decreasing the relative thickness of the composite material structure. including. In the embodiment of adjusting the bed mattress 10A, as shown in FIG. 4A, it includes adjusting the hardness of its composite material structure 15A. For example, the thickness of the material M1 having the hardness H1 is increased or decreased, and / or the thickness of the M1 having the hardness H2 is increased or decreased. For example, when the thickness of M1 is adjusted and increased, the bed surface 12A of the bed mattress 10A becomes a relatively soft surface, which is suitable for normal users who are relatively lean or have a relatively small physique index The bed mattress can be provided and its thickness can be adjusted as needed. For example, the flexible foam of M1 material that comes into contact with the user is changed from a thickness of 3 cm to 5 cm, and conversely, the thickness of the material M1 is decreased and / or the thickness of the material M2 is increased (for example, sponge To increase the thickness of the coconut thread), thereby providing a bed mattress suitable for users who are relatively heavy or have a high body mass index. In the embodiment of the bed mattress 10B shown in FIG. 4B, the adjustment of the thickness of the materials M1 and / or M2 and the means are almost the same as those in the above embodiment, and will not be further described.

  In an embodiment of the bed mattress custom-made for a user using the muscle strength measurement according to the present invention, the adjustment of the hardness of the bed mattress includes adding at least one material having a hardness different from that of the composite material structure. Including that. In this embodiment, particularly refers to adjusting the hardness of the composite material structure 15A, 15B or 15C, including adding at least one material to the composite material structure, the hardness of the added material being the hardness of the bed surface and the bed It is between the hardness of the bottom surface, which makes it possible to provide a bed mattress more suitable for the user. For example, in the embodiment of the bed mattress 10C shown in FIG. 4C, the adjustment of the hardness of the bed mattress can be performed by adding different materials to the composite material structure 15C, and the added material is M1 ~ Unlike M3, hardness is also different from H1 to H3. In an embodiment, the added material may have a hardness between H1 and H3. In another embodiment, the added material is maintained or the overall composite structure hardness is changed from soft to hard. Alternatively, the overall hardness of the composite material structure may be changed from hard to soft, thereby providing a bed mattress suitable for the user.

  As described above, in the embodiment of the bed mattress 10 made custom-made for the user by using the muscle strength measurement in the present invention, the order-made method is particularly at least by adjusting the hardness of the bed mattress 10 described above. By adjusting the hardness of the composite material structure including one material, the bed mattress suitable for the user is provided, and the spine can be supported accurately and comfortably.

  Based on the above, muscular strength measurements can also be used in the manufacture or standardization of bed mattresses to provide bed mattresses suitable for different users. Unlike the tailor-made process described above, another embodiment of the present invention may provide the user with a manufactured bed mattress so that different users can more conveniently find a bed mattress suitable for them. it can. That is, a bed mattress manufactured or standardized through the use of the above-described muscle strength measurement can provide a suitable bed mattress for a user having a similar weight, spine arc degree, or body mass index more efficiently.

  Specifically, in the embodiment of the bed mattress 100 manufactured using the muscle strength measurement of the present invention, the bed mattress 100 can be used for different users and the spinal column is substantially upright in the supine state. The degree of curvature can be made. The bed mattress 100 has different relative soft hardnesses H1, H2 .... Hn (for example, H1 <H2 <... Hn or H1 <H2 <... Hn, etc.). The user's physique index is calculated, the strength of the user's lower limbs is measured step by step, and the relative softness of the bed mattress is determined based on the user's lower limb strength. Including determining the degree of comparison with the user's fitness. Among them, the measurement of the user's lower limb strength is performed by applying an external force F to one of the user's lower limbs, and the user applies a force F ′ to act against the external force. Applying force until 'and the amount of external force F are substantially at least balanced. Among them, when the relative soft hardness of the bed mattress is determined by comparing with the user's fitness level, the bed mattress corresponding to the user's relatively large lower limb strength is defined as a bed mattress having a higher fitness level.

  In the embodiment of the bed mattress 100 manufactured using the above-described muscle strength measurement, the manufacturing process includes a bed mattress mass-produced through standardization and a providing step. FIG. 5 is a manufacturing flowchart of an embodiment that can be used in the embodiment of the present invention. As shown, it includes a mass production process 500.
