Description

Decubitus prevention mattress having even contact area}

The present invention relates to a bed restraint mattress having a smooth body contact surface, and more particularly, when the fluid is injected into the unit tube when inflated to form a contact surface in contact with the body to reduce the pressure applied to the body. Is about a mattress.

Bed sores usually occur in patients who are hospitalized for a long time or who cannot change their position freely due to cerebral spinal cord neuropathy.

A decubitus (decubitus) refers to skin injuries caused by contact of the patient's back, waist, shoulders, elbows, buttocks and hips with the floor as the skin and blood pressed down by the patient's weight are undesirable. Such bedsores are initially pale, reddening around, causing tenderness, as the blood circulation of the skin in the compressed area worsens. In this case, if symptoms worsen, blisters develop, and as the process progresses, it becomes darker and ulcers form the gangrene. Symptoms are aggravated by dangerous odors and secretions.

Therefore, in the case of a conventional mattress for preventing bedsores, a plurality of cylindrical type air support parts are formed and the air support parts are injected evenly alternately to form a cylindrical air cushion part so that the patient's body is separated from the floor. To prevent the occurrence.

An example of such an air floating mattress is disclosed in Korean Utility Model Registration No. 0168377. The disclosed bedsore-preventing fluid mattress has a structure in which a body of a patient is lifted from the floor by supplying a fluid such as water or air to a cylindrical chamber tube.

In addition, an air mat for preventing bedsores is disclosed in the Republic of Korea Patent Publication No. 2005-0090193. In the case of the bedsores prevention air mat disclosed in the patent data is composed of air pockets of a stream of air leaks in parallel and high body pressure By inducing air leakage to the part, it is said that it prevents bedsores by maximizing the distribution of weight.

However, the prior art as described above is configured such that the cross section of the mattress has a cylindrical shape as a ball shape as the mattress properties themselves are air expanded. Therefore, since the contact surface in contact with the body of the patient is formed in a curved shape when inflated, the area in contact with the body is relatively small, the pressure applied to the body is large.

According to this conventional technique, there is a problem in that it is difficult to disperse the body pressure below 32 mmHg, which is a starting pressure of clinically known pressure sores.

In addition, it is said that the air buoys alternately float up and down or left and right to disperse the body pressure, but the dispersion effect of one cell unit is extremely small, so the effect will be limited.

The present invention has been made to solve the above problems, and has a smooth body contact surface which can reduce the pressure applied to the body by smoothly forming a contact surface in contact with the body when the unit tube is expanded by the injection of fluid. The purpose is to provide a bed restraint mattress.

Another object of the present invention is to provide a bed restraint mattress having a smooth body contact surface that can change the position of the patient by inclining the contact surface left and right when the unit tube is expanded.

The bedsore preventive mattress having a smooth body contact surface of the present invention for achieving the above object is a plurality of unit tubes arranged side by side and the volume is expanded or contracted by the injection or discharge of fluid; And fluid supply means for alternately supplying fluid to even-numbered unit tubes and odd-numbered unit tubes of the unit tubes, wherein the unit tubes are connected to the body during volume expansion to reduce pressure applied to the body. It is characterized in that the smooth contact surface is formed on each of the upper contact.

The unit tubes are formed on the lower plate and the upper plate, the upper plate to form the contact surface and buoyant when the fluid is injected, and formed between the upper plate and the lower plate to form a wall surface and deformable in the vertical direction It characterized in that it comprises a side plate weave, and a smooth support means for smoothly supporting the top plate weave when supporting the top plate weave.

The smoothing support means is formed to interconnect the upper and lower fabrics, characterized in that provided with a plurality of pillars made of fiber yarn.

The smoothing support means is made of a cloth of a predetermined width, characterized in that provided with a band alternately coupled to the upper plate and lower plate weave.

The actual length of the actual column formed in the even-numbered unit tubes of the unit tube is gradually shorter as it progresses from one side to the other side, and the progressively formed column of the odd numbered unit tubes of the unit tubes is progressively progressed from the one side to the other side It characterized in that the length is formed to be longer.

As described above, according to the present invention, when air is injected into the unit tube, the surface in contact with the body of the patient is smoothly formed so as to effectively disperse the body pressure, thereby reducing the pressure applied to the body.

In addition, since a plurality of pillars are configured to connect the upper plate and the lower plate inside the unit tube, the slack of each unit tube during the inversion of the patient can take a comfortable sleep.

In addition, it is effective to prevent bedsores by varying the length of the actual column formed in the unit tube by inclining the contact surface in contact with the body when the unit tube is inflated, thereby changing the position of the patient's body to the left and right.

Hereinafter, with reference to the accompanying drawings will be described in detail a mattress for preventing bedsores having a smooth body contact surface according to an embodiment of the present invention.

1 to 3, the mattress 10 according to an embodiment of the present invention is provided with a plurality of unit tubes 20 therein, the unit tubes 20 is a cover material of a conventional mattress ( 15) has a structure surrounded by. Of course, the cover member 15 may be omitted, of course.

The unit tubes 20 are arranged side by side in a number of rows. In this case, the arrangement direction of the unit tubes 20 is disposed in the same direction as that of the patient lying down, that is, in the vertical direction of the mattress 10. And each unit tube 20 is formed long in the direction intersecting the direction in which the patient is lying, that is, the left and right directions of the mattress 10.

The unit tube 20 has an inner space 29 sealed therein, and the volume of the inner space 29 may expand or contract as fluid or air such as air or water is injected into or discharged from the inner space 29. It is configured to be. In the illustrated example, air is injected into the inner space 29 of each unit tube 20 as a fluid.

The air is injected and discharged alternately in odd rows of unit tubes 20a and even rows of unit tubes 20b. To this end, a fluid supply means for alternately supplying fluid to even-numbered unit tubes 20a and odd-numbered unit tubes 20b is provided.

As an example of the fluid supply means, a first duct connecting the air injection pipes 31a and 31b formed in each of the unit tubes 20 and the air injection pipes 31a of the odd number of unit tubes among the unit tubes 20 33a), the second duct 33b connecting the air injection pipes 31b of even-numbered unit tubes among the unit tubes, and the first and second ducts 33a and 33b to be connected to each other. A pump 35 for supplying air of a constant pressure to the second duct and the first and second ducts 33a and 33b are respectively installed to open and close the flow paths of the first and second ducts 33a and 33b. The control unit 39 controls the opening and closing of the first and second three way valves 37a and 37b and the operation of the pump 35.

When the air of a constant pressure is discharged from the pump 35, the first three-way valve 37a opens the flow path of the first duct 33a by the control of the controller 39 so that the air flows into the tubes 20a of odd rows. To be supplied. As the air is injected, the unit tubes 20a in odd rows are expanded and the upper surface of the unit tubes 20a is supported. In this case, the second three-way valve 37b opens the flow path of the second air discharge pipe 38b under the control of the controller 39 so that air is discharged from the even-numbered unit tubes 20b.

Then, the first three-way valve 37a opens the first air discharge pipe 38a by the control unit 39 so that air is discharged from the odd number of unit tubes 20a and at the same time, the second three-way valve 37 37b) opens the flow path of the second duct 33b so that air is supplied to the even-numbered unit tubes 20b through the second duct 33b. When air is injected into the even-numbered unit tubes 20b, the upper surface of the unit tube 20b is supported while expanding.

Fluid supply means to be applied to the present invention can be of course well-known in the art, in addition to the above-described configuration, each unit tube can be alternately expanded and contracted.

In the present invention, the unit tubes 20 each have a smooth contact surface 21 is formed on the upper portion in contact with the body during volume expansion in order to reduce the pressure applied to the body. Since the contact surface 21 widens the area in contact with the body, the load of the body acting on the contact surface 21 can be dispersed in a large area, thereby greatly reducing the body pressure of the patient acting on each unit area compared with the prior art. Can be.

The unit tube 20 is largely provided with a lower plate weave 23, an upper plate weave 21, a side plate weave 25, smoothing support means. The lower plate weave 23, the upper plate weave 21, the side plate weave 25 is made of a fabric. As an example, the thin monofilament yarn of synthetic resin is woven at high density using warp and weft yarns. And heat-sealing resin such as PVC or urethane is fused to the surface of the lower plate, upper plate, side plate weave for sealing.

The unit tube 20 configured as described above has a space 29 formed therein, and when air is injected into the internal space 29, the unit tube 20 is expanded to support the upper plate 21 by the pressure of air. do. In this case, the top plate 21 forms a contact surface in contact with the body of the patient. When the air is injected, the upper plate weave 21 is provided with smoothing support means to be supported while forming a smooth surface.

One example of the smoothing support means is provided with a plurality of pillars 27 formed to interconnect the upper plate 21 and the lower plate 23. One threaded column 27 may be formed by twisting one strand of fiber or several strands of fiber. The thread column 27 connecting the upper plate 21 and the lower plate 23 is connected to the loop yarn at regular intervals along the supply direction of the inclination constituting the upper plate 21 and the lower plate 23. It can be formed integrally by weaving spaced apart from the lower plate weave at regular intervals. Alternatively, the upper and lower portions of the yarn column 21 may be cross-bonded or knotted to yarns constituting the upper plate weave 21 and the lower plate weave 23.

When air is injected into the unit tube 20 by the thread column 27 as described above, the upper plate 21 and the lower plate 23 are spaced apart by the vertical length of the thread column 27. That is, the supporting height of the upper plate weave 21 is limited by the length of the thread column 27. Preferably, the arrangement of the thread columns 27 allows about 30 to 50 thread columns 27 to be formed per unit area (cm ² ). If the number of thread columns 27 is 30 or less per unit area, the flatness of the upper plate weave is reduced when the unit tube 20 is expanded. In the illustrated example, the lengths of the thread columns 27 are all the same. When the air is injected a plurality of pillars 27 of the same length to pull the top plate 21 with the same force, so that the top plate 21 can form a smooth contact surface.

When the air is discharged, the air pressure inside the unit tube 20 is lowered, so that the volume of the unit tube 20 shrinks as shown in FIG. 3. The unit tube is contracted so that the height of the upper plate 21 is lowered, and accordingly, the heights of the thread column 27 and the side plate 25 are also lowered so that the yarn column 27 and the side plate 25 are straightened up and down. It is changed into a crumpled shape in several places from side to side in the state.

According to the present invention having the above-described structure, since each of the thread columns 27 is connected to the upper plate weave 21 and the lower plate weave 23, the body pressure distribution of the patient is not only effective but also greatly reduces the slack when the patient turns over. On the other hand, in the related art of preventing bedsores, when air is injected into the unit tubes, the upper portion of the unit tube in contact with the body swells in a circular shape. Therefore, since the contact surface in contact with the body is formed in a circular shape and the contact area is narrowed, the effect of body pressure dispersion is low and the body pressure is increased. This conventional method causes the body to shake violently from side to side when the patient inverts the body, thereby significantly lowering the patient's sleep desire.

Meanwhile, as illustrated in FIG. 7, the lengths of the pillars formed in the unit tubes may be different from each other. Detailed description will be described later.

Another example of the smoothing support means is shown in FIG. 4. Inside the unit tube 20, two rows of bands 37 extending in the longitudinal direction are formed side by side. The band 37 is made of a cloth having a constant width to allow deformation. In addition to cloth, materials such as leather, resin, and paper may be used. Band 37 is alternately coupled to the upper plate weave 21 and the lower plate weave 23 is formed as a W-type as a whole. Preferably, as shown, when two bands 37 are formed side by side, when one band is coupled to the upper plate 21, the other band is coupled to the lower plate 23, and one of the bands is lower plate weave ( 23, the other band is coupled to the top plate 21 to form a symmetrical shape so that the top plate 21 when the expansion of the unit tube 20 has a smooth surface. And of course, in addition to the two bands shown can be formed of one or three or more bands.

The combination of the band 37 and the upper plate weave 21 or the band 37 and the lower plate weave 23 may be used for bonding bonding, heat fusion using a resin, stitched using a thread.

When air is injected into the unit tube 20, the band 37 connects the upper plate 21 and the lower plate 23 in the vertical direction, thereby limiting the support of the upper plate 21 to a predetermined height. In this case, the upper plate weave 21 forms a smooth surface.

The operation of the mattress of the present invention having the above-described configuration is shown in FIG. By the air supply means mentioned above, air is alternately injected into the odd-numbered rows and even-numbered unit tubes 20a, 20b. For example, when air is injected into the odd-numbered unit tubes 20a, each unit tube 20a is expanded and the upper portion is supported. In this case, since each unit tube 20a of odd rows has a flat surface, the body pressure of the patient may be evenly distributed on the contact surface in contact with the body, thereby lowering the body pressure.

Another embodiment of the present invention is shown in FIG. 7 is a cross-sectional view of the unit tube for showing the inside of the odd-row unit tube applied to the mattress in FIG.

6 and 7, the actual column 57 formed in the odd-numbered unit tubes 50a among the unit tubes 50 may be gradually shortened in length from one side to the other side, and may be even-numbered units. The seal column (not shown) formed in the tubes 50b is formed to gradually increase in length from one side to the other side.

Therefore, when the odd-numbered unit tube 50a is expanded, the upper plate 51 is formed to be inclined gradually to the right rather than the left side, and the left side is gradually inclined to be gradually lower than the right-side when the even-numbered unit tubes 50b are expanded. Is formed. The inclination direction of the odd-numbered unit tubes 50a and the inclination direction of the even-numbered unit tubes 50b are configured to be reversed. Unlike the above, the inclination directions of the odd-numbered rows and the even-numbered unit tubes 50a and 50b may be interchanged.

According to the present invention having the above-described configuration, when the odd-row unit tube 50a is expanded, the patient moves from left to right, and when the even-row unit tube 50b is expanded, the patient is moved from right to left. Will move. As such, by moving the center of the patient's body to the left and right to change the position is effective in preventing bedsores.

Meanwhile, in the above-described embodiments of the present invention, the fluid injected into the unit tube is described as being air, but water may be used in addition to air.

Although the present invention has been described with reference to the embodiments illustrated in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments thereof are possible.

Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
