Description

The present invention relates to a bedding and a technique related to the production thereof.

Futon has been vaguely said that sleeping posture and body pressure distribution are important. If the bedding is too elastic, the lumbar region will drop and the sleeping posture will worsen, causing back pain. On the other hand, if the elasticity is made to correspond to the weight distribution in the sleeping posture and the weight is supported, the sleeping posture is improved, but the body pressure distribution is deteriorated. The sleeping posture and body pressure distribution are in a trade-off relationship, so it seems that both the body pressure distribution and the sleeping posture are optimal, with one of the three quilts lying on the back of the waist. There is no bedding to adjust.

The bedclothes for elderly people, sick people, and physically disabled people as well as general healthy people have many problems such as prevention of pressure ulcer and back pain, sanitary properties, etc., for comfortable sleep, pressure ulcer prevention, back pain prevention, etc. Therefore, bedding that provides optimal body pressure distribution and sleeping posture is important. Body pressure distribution and sleeping posture differ depending on individual characteristics such as physique and weight and the elasticity of the bedding, and are measured according to the relationship between the bedding and the individual who uses it, and are adjusted to be optimal for the person who uses the bedding. There must be. The problem to be solved by the present invention is how to make a bedding that adjusts both the sleeping posture and the body pressure distribution, which are considered to be a contradictory relationship, in an optimal manner.

The problems to be solved by the present invention are the following items.
1. 1. A method of adjusting both the sleeping posture and the body pressure distribution so that both are optimal. How to make bedclothes have the necessary elasticity distribution

While measuring the sleeping posture and body pressure distribution in the supine and recumbent positions of an individual using a futon, the elasticity distribution is calculated so that the sleeping posture and the body pressure distribution are optimal for the person using the bedding. Manufacture bedding with sex distribution.

Specifically, the subject is laid down on a measurement quilt with many blocks with different elasticity, and the sleeping posture and body pressure distribution are measured by the sleeping posture measuring device and body pressure distribution measuring device in the supine and lateral positions. However, the blocks are exchanged so as to be optimal, and the optimal body pressure distribution and the elasticity distribution so that the sleeping posture is obtained are obtained. Manufactured by laying bedding with this optimal body pressure distribution and elasticity distribution that will give you a sleeping posture by cutting out the necessary parts of the bedding and replacing this part with different elastic pieces of the same size To do.

1. A method of adjusting both the sleeping posture and the body pressure distribution so that both are optimal 1) In the bedding with too much elasticity, the waist falls and the sleeping posture is deteriorated, which causes back pain. On the other hand, if the waist is supported in a hard futon with the idea that the elasticity will correspond to the weight distribution (head, chest, waist, thigh, lower leg), the sleeping posture will improve, but the body pressure distribution Becomes worse.

2) It is said that the lateral position is good for apnea syndrome, but in the case of uniform hardness, the lateral position cannot be maintained for a long time due to pressure on the lower arm in the lateral position.

3) The hips and sacrum of the lower limbs are particularly easy to develop pressure ulcers, and some measures are required.

As a concrete measure against the above three points, it can be solved by changing the elasticity of the quilt finely depending on the part. With respect to 1) above, the body pressure distribution can be improved without deteriorating the sleeping posture by slightly removing the support from the maximum weight part. For 2), by increasing the elasticity of the shoulder in the lateral position, the sinking of the shoulder improves, and the lateral position can be maintained without difficulty for a long time. Use a proper sleeping posture for improvement. It should be noted that the optimal elasticity of the shoulder quilt is related to the height of the pillow, and the optimal height of the pillow cannot be determined simply by measuring the shape of the cervical vertebra. Pillows must be discussed in relation to the elasticity distribution of mattresses. The optimum value for the pillow height is high for stiff futons and low for high-elasticity futons. It is necessary to satisfy the conditions in the supine position and the lateral position, but the values in the lateral position are as follows.
Pillow height = (shoulder width-head width) / 2-sinking amount of bedding ".
For 3), increase the elasticity of the place where pressure ulcers are likely to occur, and keep the body pressure low.
Thus, in order to adjust both the sleeping posture and body pressure distribution optimally, it is possible to solve the problem by using a `` bedclothing with a distribution of elasticity '' that finely changes the elasticity of the mattress depending on the region. it can.

The sleeping posture and the body pressure distribution were thought to be a trade-off, but the bed pressure that can change the elasticity distribution can improve the body pressure distribution without deteriorating the sleeping posture. By measuring the sleeping posture and the body pressure distribution, it is possible to provide an optimal bedding for each individual to be used having an elastic distribution according to the individual characteristics such as height and weight. Optimum bedding can be provided for each individual to use, and it is expected to have a great effect on the prevention and treatment of pressure ulcers and the improvement of apnea syndrome.

2. Elasticity distribution measuring device that adjusts both sleeping posture and body pressure distribution optimally 1) Laying bedding for measuring the elasticity distribution can be changed arbitrarily. The block is replaced so that the optimal elasticity distribution is obtained while measuring the sleeping posture and the body pressure distribution.

2) Sleeping posture measuring device (FIGS. 2, 3, 4, 5, and 6)
(2.1) Definition of the sleeping position in the supine position Looking at the human body lying in the supine position on the bedding from the side, a line connecting the height from the center horizontal plane of the upper and lower thickness from the tip of the foot to the top of the head Define a supine sleeping posture curve as a function of the distance from the toes. A case where the patient is laid on a horizontal hard platform in a supine position is defined as a supine standard sleeping posture curve.

(2.2) Method for measuring the sleeping position in the supine position The sleeping position in the supine position is measured according to the following procedure.
・ A measuring device on the upper surface of the human body of the measuring device placed on the horizontal measuring table of the measuring device described in the next section in a supine position and placed horizontally above the midline in front of the human body. Measure the dimensions from the top of the head from the top of the head to the pubic area as a function of the distance from the toes.
• Measure the dimensions of the front surface of the front surface of the right or left lower limb as a function of the distance from the heel to the toes.
This is the curve in front of the supine position as a function of the distance from the toes, connecting from the top of the head to the toes.
・ Next, with the measuring device on the lower surface of the human body of the measuring device described below installed horizontally below the midline on the lower surface of the human body, the distance from the top of the head to the pubic region is measured from the base of the central surface of the lower surface of the human body. As a function of
• Measure the dimensions from the base surface of the lower surface of the right or left lower limb from the thigh to the toes with a measuring instrument on the underside of the human body as a function of the distance from the toes.
・ This is a curve of the lower surface of the supine position as a function of the distance from the tip of the foot, connecting from the top of the head to the tip of the foot.
A function of the distance from the tip of the foot, which is an average of the curve of the supine front and the curve of the supine bottom, is the supine sleeping posture on the flat plate, and the supine reference sleeping posture curve.
The function of the distance from the toes obtained by subtracting the curve of the lower surface of the supine position from the curve of the front surface of the supine position is the vertical thickness of the human body, and this is the reference thickness function of the standard sleeping posture of the supine position.
・ Place the person to be measured in a supine position on an actual bedding laid on a horizontal measuring table of the measuring device, and follow the same procedure as in 1 to 7 above to set the curve on the front of the human body and the curve on the lower surface of the human body Measure as a function. A function obtained by averaging the curve on the front surface of the human body and the curve on the lower surface of the human body is defined as an actual sleeping posture curve of the bedding.
・ To obtain the supine position curve simply, place the person on the actual bedding, measure the curve in front of the human body in the supine position as a function of the distance from the toes, The value of the reference thickness function of the posture is subtracted to obtain the approximate sleeping posture posture curve of the bedding.
This actual sleeping posture curve is compared with the sleeping posture optimum curve and used for the evaluation of the sleeping posture. If this difference is corrected with the optimal sleeping posture curve as a straight line, the optimal sleeping posture is obtained.

(2.3) Measuring device for measuring the shape of the supine position A hole is formed at equal intervals in a rod-like material that is horizontally installed above the measured person lying in the supine position and is longer than the measured person's height. Insert a thin rod of a certain length into contact with the body of the person to be measured, and read the scale on the scale plate installed on the bar for the length remaining on the bar. A shape measuring device for the upper surface of a human body in the supine position for measuring the distance from
In addition, a hole is made in the measurement table at equal intervals at the midline of the measurement subject who is laid in a supine position on a horizontal measurement table and the center line of the left and right lower limbs. By inserting from the bottom until it comes into contact with the body of the subject and measuring the remaining length, a shape measuring device for the lower surface of the human body in the supine position that measures the distance from the horizontal plane of the subject is obtained.

When measuring the sleeping posture when sleeping in an actual futon, place a futon on the measuring table and insert the measuring rod into the hole through the futon. At this time, place the measuring rod on the lower surface of the human body. If you are following the procedure below.
・ Put a futon on the measuring table, and insert a thin pointed needle into the hole of the measuring table with a guide so that it is perpendicular to the measuring table. Get out of.
・ Put the end of the measuring rod on the underside of the human body from the top into the tip of the needle and push it down to the position of the measuring rod stopper.
・ Install measuring rods in all holes of the measuring table and lay the person to be measured on the futon.
・ Measure the length of the measuring bar that is under the measuring table.
・ When measuring, measure the point where there is a gap between the futon and the human body by pushing up the measuring rod until it touches the human body.
When the bed is deformed by weight, the measurement is performed from a reference surface provided on the floor or lower part as shown in FIG.

(2.4) Definition of the sleeping position in the supine position Seen from the side of the human body laid on the bedding in the lying position with the legs extended, from the height of the midline curve of the upper body from the horizontal plane, from the horizontal plane in the center of the lower limbs A line connecting the height of the toe from the tip of the foot to the top of the head is defined as a sleeping posture in the lateral position as a function of the distance from the tip of the foot.

(2.5) Method of measuring the sleeping posture in the recumbent position The subject is placed in the lying position in the posture in which the lower extremities are stretched on the bedding after placing the index on the midline on the back while standing, and the horizontal plane of the midline curve of the upper body Measure the dimension from the toe as a function of the distance from the toes, measure the midline curve of the lower limbs as a function of the distance from the toes with the following T-shaped measuring device sandwiched between the legs. Connect from the top of the head to the tip of the foot to make the sleeping posture in the lateral position. At this time, the head is covered with a cap so that the center line can be marked. If the optimal value of the sleeping posture in the lateral position is a straight line and the difference is corrected, the optimal sleeping posture is obtained.

(2.6) Measuring device for sleeping posture in lateral recumbent position The cross section from the crotch to the tip of the foot consists of a flexible plate with a T-shape, measuring the center line of the lower limbs between the legs Devised a measuring instrument to do.

3) Body pressure distribution measuring device A “body pressure distribution measuring device” that can measure body pressure at a pitch of about 30 mm in length and about 30 mm in width is used.

3. How to give the bedding the necessary elasticity distribution The method to give the bedclothes the elasticity distribution is to cut out part or several parts of the bedclothes or mattress and make the elasticity of the same size as the cut out parts. This is possible by providing a resilient distribution by replacing different mattresses or mattress pieces. It is also possible to distribute the filling amount of the futon padding.
Cut out the part (part or several parts) you want to change the elasticity of the mattress or mattress, and replace it with a piece of mattress or mattress that has the same elasticity as the cut out part and replace it with any elasticity We devised a method to create a bedding with a distribution. It can be replaced, but it can be done without gluing the cut out part by gluing the replaced part with the main body, putting the bottom plate in the whole, or wrapping the whole with cotton pad.

4). Laying bedding with elastic distribution The following bedding is wrapped with a cover.
1) Custom bedding tailored to the individual (bedding 1)
Using the “laying bedding for measurement that can change the elasticity distribution arbitrarily”, “measuring device for sleeping posture”, and “body pressure distribution measuring device”, the supine sleeping posture, the lying supine sleeping posture and the body pressure distribution The elasticity of the bedding is adjusted so that the optimum value is obtained, so that the bedding becomes the optimal elasticity distribution for the individual.

2) Bedding with standard elasticity distribution (Bedding 2)
By using the method described in the previous section, a lot of “bedclothes with an optimal elasticity distribution for individuals” are created, and the bedclothes with a standard elasticity distribution are used.

3) Bedding with a bottom plate (bedding 3)

4) Bedding wrapped in rolled cotton (bedding 4)
A bedding with a resilience distribution that wraps the whole with cotton cotton without bonding the cut piece to the body.

5) Bedding with bedding fillings distributed (bedding 5)
Bedding bedding with a distribution of elasticity by distributing the filling amount of futon batting.
You can also set up a pedestal to partition and insert batting.

6) Bedding that can be folded in three (bedding 6)
The above bedding is folded in three for easy storage.

Elderly people often have illness and physical disability, so they spend more time in bed and futon. When the sleeping posture and body pressure distribution become poor, back pain and wounds can occur. The present invention can be adjusted to be suitable for a person who uses a sleeping posture and body pressure distribution so that a general person and an elderly person can take a comfortable sleep by preventing back pain and wounds. In addition, it is effective as a bedding that does not apply body pressure by increasing the elasticity of the surgical section after the operation of a wound wound such as a spinal cord injury person, and can be applied to the bedding of elderly and spinal cord injury persons. In addition, it is said that the lateral position is good for apnea syndrome, but in the case of uniform hardness, the lateral position cannot be maintained for a long time due to compression of the lower arm in the lateral position. Increasing the elasticity of the shoulders in the lateral position improves the sinking of the shoulders and can maintain the lateral position without difficulty for a long time, making it a suitable sleeping posture for improving apnea syndrome I can do it.
Although the sleeping posture measurement method and measuring device can actually measure the sleeping posture of the person who uses the bedding in the supine and lateral positions, the sleeping posture and body pressure distribution seemed to have a trade-off relationship, With the bedding that can change the elasticity distribution, the body pressure distribution can be improved without deteriorating the sleeping posture.
