Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a smart-

The present invention relates to a fiber-based active smart pad, and more particularly, to a smart pad which is capable of maintaining the best sleep state by moving or moving an external force applied to a human body placed on a surface, Based active smart pad capable of performing a beneficial action on the health of the human body by allowing various additional devices to be easily installed.

Beds have been used mainly in hospitals for easy sleeping and convenient arrangement of bedding. However, in recent years, they have been used as bedding in most homes due to modernization of living, conversion of residential culture into co-housing.

The bed consists of a bed body and a mattress installed on the bed body, and the mattress is divided into a spring mattress, a latex mattress, a stone mattress, and an ocher mattress according to the material and cushioning method applied.

Beds with spring mattress or latex mattress have a cushioning function compared to the ondol, so they can provide comfort and comfort at bedtime, but they have very cold disadvantages in winter because there is no separate heating system.

For this reason, many users of the mattress use the mattress top surface with an electric heater that can perform a heat action such as an electric mattress.

For example, Korean Utility Model Registration Application No. 20-1998-0010429 proposes a "thermostat for two-person heating bed" in which a thermostat can be performed only in a part where a user wishes to heat in a double bed.

In the temperature control device for the two-person heating bed, the heating wires (A) and (B) are arranged on both sides of the center line of the bed, so that the heating wires can be conveniently used while selectively heating the left and right heating wires.

However, the above-described conventional heat transfer bedding has an advantage that it can provide a warm sleep by applying heat to a sleeping person. However, since the structure of the synthetic resin sheet has a built-in heat ray, the air can not flow upward and downward, It can not provide a sleeping environment and causes skin troubles due to poor discharge of sweat.

In addition, in the conventional heat conductive bedding, when the elderly person or patient who can not freely move his / her body is used, an image is generated due to exposure to the local heating of the heat ray.

Particularly, the conventional electrothermal bedding is merely a seat to be used in a form in which a sleeping person lies on the bedding surface and can not move or move the position of the sleeping person by itself, so that it can not only cause a pressure ulcer when the elderly person or patient can not move freely, There is a problem that the pressure ulcer is more seriously deteriorated when a patient with a pressure ulcer is used.

FIG. 10 is a perspective view of a fiber-based active smart pad according to a fourth embodiment of the present invention, and FIGS. 11A and 11B are views for explaining the operation of a fiber-based active smart pad according to a fourth embodiment of the present invention. to be. FIGS. 11A and 11B show the front and side sections cut away in order to facilitate understanding. FIG. 11A and FIG. 11B show a state in which the main part is omitted and the displacement of the human body driving part on the cross sectional area is simplified Respectively.

10 to 11B, a fiber-based active smart pad according to a fourth embodiment of the present invention includes a sheet base 5 formed in a planar shape, The human body driving part 8 is formed in a hollow body having an area corresponding to the upper part of the sheet base 5 and partitioned into a plurality of air chambers by partition walls.

The hollow body 81 includes an upper arm 811 woven by weft and warp as shown in the enlarged part, a woven fabric by weft and warp, and a parallel spaced apart arrangement 814 below the upper woven A lower yarn 812, a connecting yarn 813 connected between the upper and lower loops, and a sealing layer 815 hermetically sealing the spacing space 814. At this time, each layer of the hollow body 81 is partitioned into a plurality of air chambers by the sealing layer 815 formed in the vertical direction in the form of a partition wall.

The hollow body 81 may be composed of at least one layer, but in the present embodiment, it is composed of two layers. At this time, each layer of the hollow body 81 can be divided into various shapes, but in this embodiment, as shown in FIG. 10, one hollow body 81a (hereinafter referred to as a one-stage air chamber) , And a hollow body 81b of two layers (hereinafter referred to as a two-stage air chamber) is divided into six.

In addition, the sealing layer 815 is formed in such a manner that a gas-tight sheet such as a thin synthetic resin sheet is adhered and adhered to the upper and lower surfaces of the upper and lower surfaces 811 and 812.

The operation of the fiber-based active smart pad according to the fourth embodiment of the present invention will be briefly described with reference to FIGS. 11A and 11B.

When a patient's bed position is changed while a fiber-based active smart pad is installed on a bed of an unconscious patient who can not freely move his / her body, as shown in FIG. 10, The air in the first and second air chambers 81a and 81b on one side adjacent to the point where the patient is lying is exhausted and the air in the first and second air chambers 81a and 81b on the other side adjacent to the point where the patient lies, The body part of one side of the patient (shown briefly in cross section of the human body) is gradually lifted up.

Thereafter, when the two-stage air chamber 81b is expanded to the maximum, the body of the patient rotates, and the front portion (abdomen portion) of the human body is moved to the surface of the hollow body 81 where air is removed.

When the patient p is rotated by 180 degrees, air is exhausted into the first and second air chambers 81a and 81b as shown in FIG. 11B, and the first and second air chambers 81a and 81b, When the air is gradually injected into the two-stage air chamber gradually, the body part of the patient is gradually lifted. When the two-stage air chamber 81b is inflated to the maximum, the patient's body rotates in the opposite direction The back portion (back portion) of the human body is restored to the hollow body surface of the air-removed portion.

Thereafter, the air in the first and second stage air chambers 81a and 81b on one side and the other side are exhausted or injected so that the height of the hollow body 81 is flattened, so that the air is adjusted to a proper shape on the water surface.

If the position of the patient is changed by changing the position of the patient's sleeping position every predetermined time in the above-described manner, the patient can be protected from skin diseases such as a pressure ulcer. In addition, even in the case of the general public, it is possible to improve the health by adjusting the position of the sleeping position at a predetermined time.

On the other hand, the human body driving unit 8 is formed of a hollow body having a multi-layer structure formed by dividing the air chamber into a plurality of air chambers by a sealing layer formed in the vertical direction in the form of a partition wall, and partition walls partitioning the air chamber of the hollow body are formed into different shapes .

For example, if the partition of the hollow body 81 is formed in a shape similar to the shape of the human body, the air chamber has a shape similar to that of the human body. Therefore, if the air is injected and discharged, And it is also possible to effectively perform an operation of moving the human body.

As described above, the present invention is not limited to the above-described embodiments, but rather may be applied to other types of smart pads, such as the present invention It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
