The bedsore prevention mattress according to the present invention is used to easily change the position of the patient (H) to the left or right with the help of a guardian after seating the bedridden patient (H), and the configuration is in contact with the floor. A mattress provided with a first contact surface 10 and a second contact surface 20 formed symmetrically on both sides of the first contact surface 10 and formed at a predetermined inclination angle from bottom to top so as to be inclined to the left or right It is formed on the upper surface of the body portion 1 and the mattress body portion 1 and can be largely divided into a seating portion 30 in which buffer surfaces 31 of different heights and intervals are formed so that a patient can be seated.

Hereinafter, the configuration of the present invention divided as described above will be described in detail with reference to the illustrated drawings.

First, the mattress body (1) is,

As described above, the first and second contact surfaces 10 and 20 and the seating portion 30 may be largely divided, and the mattress body portion 1 may have an elastic force. That is, it may be composed of a foam material having a restoring force so as to more comfortably support the patient H lying for a long time. For example, any one or a plurality of materials of memory foam, latex, and polyurethane foam may be selectively used.

In addition, the mattress body portion (1) from the bottom to the top, that is, from the first and second contact surfaces (10, 20) toward the seating portion (30) a plurality of cushion layers (1a) made of a material of high elasticity to low elasticity ) can be stacked. That is, the layer located on the bottom side can have a high elasticity material to support and balance the weight of the patient (H), and the layer located on the top surface can provide a soft cushioning feeling to the patient (H) lying down. It may have a material of low elasticity.

On the lower surface of the mattress body (1), it may be composed of the aforementioned first contact surface 10 and the second contact surface (20).

The first contact surface 10 may be formed flat in the longitudinal direction while being positioned on the lowermost surface of the center of the mattress body 1, and the second contact surface 20 is symmetrical on both sides of the first contact surface 10 described above. A predetermined inclination angle θ may be formed from bottom to top so as to be inclined to the left or right. In other words, the central part is narrow and the other parts are wide and inclined to form an inverted triangle shape. Here, the aforementioned constant angle of inclination (θ) refers to between 25° and 35° that can be easily operated without a large force when the guardian tilts the mattress main body 1 to the left or right. may be preferable. Of course, it is not limited to the range of the angle of inclination described above, it can be applied to a range of inclination angles according to the size or shape of the mattress main body (1).

Therefore, in normal times, the first contact surface 10, which is flat, is brought into contact with the floor so that the mattress body 1 can be used for the same purpose as a general bed. It is possible to easily change the position of the patient H by selectively tilting it in the left or right direction through the two contact surfaces 20 .

The seating part 30 is

It is formed on the upper part of the mattress body (1) described above to seat the patient (H). At this time, by forming the buffer surfaces 31 of different heights and intervals for each part of the patient H in the seating portion 30 , the load concentrated on a specific part when the patient H is lying can be distributed. In other words, it is possible to ergonomically design the areas in contact with the patient's back, buttocks, and heels to distribute the weight concentrated on the above areas to relieve pain or fatigue even when lying down for a long time.

On the other hand, a plurality of ventilation passages 32 may be formed in the seating portion 30 to provide ventilation along a section where the load of the human body is concentrated. In this case, it may be desirable to form evenly over the entire area of the seating portion 30, and the shape of the ventilation path 32 does not need to be set to any one shape, and any shape is irrelevant as long as it has an easy ventilation structure. .

In addition, a plurality of concave air cushion grooves 33 may be formed in the seating portion 30 . The shape of the air cushion groove 33 does not need to be determined in any one shape, and can be applied in various ways, such as a paper cup shape, a square shape, a spherical shape, and may be formed in a cylindrical shape as shown in the present invention.

Accordingly, the air cushion groove 33 is pressurized by the load of the patient H lying on the seating portion 30 , and air circulates through the ventilation path 32 while the air cushion groove 33 is pressurized. It is possible to provide a comfortable environment to the patient (H) by generating

The escape prevention wall 40 is,

It may be formed at a predetermined height on the upper left and right sides of the seating part 30 . This helps to prevent the departure of the patient (H) seated in the seating portion 30 when the mattress body portion 1 is inclined in the left or right direction. In the present invention, although illustrated as a bar shape, the shape of the anti-separation wall 40 can be variously implemented through ergonomic design without having to be determined in any one shape, of course. In addition, it may be preferable that the separation prevention wall 40 is made of a material having elasticity, that is, similar to or the same material as the mattress main body (1).

The leg separation wall 50 is,

It may be formed at a predetermined height from the center of the upper portion of the seating portion 30 . This helps prevent the both legs of the patient (H) seated on the seating part 30 from interfering with each other when the mattress body part 1 is inclined in the left or right direction. The shape of the leg separation wall 50 does not need to be set to any one shape, and any shape is irrelevant as long as it is a structure that can comfortably and stably separate and support the leg of the patient H. In addition, it may be preferable that the leg separation wall 50 is also similar to or made of the same material as the aforementioned mattress body (1).

On the other hand, in another embodiment, the leg separation wall 50 may be formed to be detachable from the seating portion 30 described above. That is, it can be replaced with the leg separation wall 50 with size, shape and functionality added to fit the body type of each patient H, or it can be removed and used as needed. More specifically, a guide groove 30a formed in the longitudinal direction may be provided on either side of the upper surface of the seating part 30 , and a shape corresponding to the guide groove 30a is formed on the lower surface of the leg separating wall 50 . of the fitting protrusion 50a may be integrally formed. Accordingly, by sliding the fitting projection (50a) to the guide groove (30a) in the longitudinal direction, it is possible to facilitate the detachment of the leg separation wall (50) from the seating portion (30).

On the other hand, although not shown in the drawings, the mattress body 1 may be used with a separate cover (not shown) covered. At this time, the high-density fabric material with breathability and water resistance to prevent contamination or damage to the surface without affecting the breathability and buffering properties of the mattress main body (1), that is, as the outer material of the outer covering of mountaineering clothing, tents, and sleeping bags It is commonly used, for example, it may be preferable to use a functional fabric such as Gore-tex.

A method of using an anti-bedsore mattress according to an embodiment of the present invention having the above structure will be described as follows.

First, the mattress body part (1) is installed in a place to be used. At this time, although there is no great limitation in the place, it is preferable to install it on a flat floor of a room or a bed frame.

Then, the protector to protect the patient (H) seats the patient (H) on the seating portion 30 of the installed mattress body (1). At this time, it is possible to lift and seat the patient (H), but if not, tilt the mattress body (1) in the direction in which the patient (H) is located, and then sequentially move the lower body and upper body of the patient (H) It can also be anchored.

If the patient H is seated on the seating part 30 in this way, the first contact surface 10, which is normally formed flat, is brought into contact with the ground to maintain the seating part 30 in a flat state, which is the same as a general bed. use for the purpose At this time, the load of the patient (H) is distributed through the ergonomically designed buffer surface (31) to relieve pain or fatigue of the patient (H) lying for a long time.

In addition, ventilation and cushioning properties are improved through the ventilation path 32 and the air cushion groove 33 evenly formed throughout the seating portion 30 to provide a comfortable feeling to the patient H.

On the other hand, the patient (H) is required to continuously change the position at intervals of 2 to 4 hours in order to prevent physical fatigue and pressure sores. According to this request, one caregiver holds the mattress body part 1 and gradually tilts it in the left or right direction, and the center of gravity of the patient H moves in the direction in which the mattress body part 1 is inclined. Accordingly, the caregiver can naturally change the position of the patient (H) without much effort.

At this time, through the separation preventing walls 40 formed on both sides of the seating portion 30 , the patient H is prevented from leaving the seating portion 30 .

In addition, the leg separation wall 50 formed in the region where the legs of the patient (H) is located stably supports both legs of the patient (H) to which the center of gravity is moved, so that the legs are not crossed or confused.

In addition, the above-described leg separation wall 50 may be used by removing it from the seating part 30 or replacing it with another shape, shape or functionality added in some cases.

On the other hand, when the center of gravity of the patient (H) seated on the seating portion 30 is biased to either side, the mattress body 1 may inadvertently incline. Accordingly, an unintentional inclination may be prevented in advance by providing a separate chock (not shown) on the lower surface of the second contact surface 20 facing each other. However, considering that the anti-bedsore mattress of the present invention is intended for a patient who cannot move by itself, the above-described chock may be excluded from the essential configuration.

As described above, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the described content. Therefore, the scope of the described content does not need to be limited to the described embodiments, and should be defined by the claims described below as well as the claims and equivalents.
