The present invention relates to a mattress assembly, and more particularly, to a mattress assembly capable of increasing the bearing capacity of a portion that receives a large load and minimizing a pressure for supporting the body on a diseased part during treatment, And an automatic back pressure regulating device that can prevent the back pressure of the mat.

Generally, the mattress used by the elderly people or the elderly is made of a material having elasticity or cushion. Therefore, when the patient is lying down or sitting, the pressure applied to the body contacting the mattress varies depending on the body weight of the patient. Particularly, when the affected part is located at the part contacting the mattress when the molten part is not lying, excessive pressure is applied to the affected part, which may adversely affect the treatment of the affected part. In particular, patients who are lying on the mattress of a bed for a long time because of their uncomfortable behavior often have a skin injury (bedsore) caused by the contact of the back, waist, shoulder and elbow with the floor. These pressure ulcers can be seen in patients who have not been able to freely change their position due to a debilitating patient or cerebrospinal nerve disorder for a long time, and they are prone to appear in areas where stress is applied, especially where bones are exposed.

As described above, the skin of the part pressed by the load of the body becomes pale because the blood circulation deteriorates, and the circumference becomes red and tenderness occurs. Particularly, when the affected part is severely pressed by the external force during the treatment of the affected part, there is a problem that the blood circulation is not smoothly performed and the treatment period is lengthened as described above. In order to prevent the affected part from being pressed, There is a problem.

[ A unit cushion member 200 is installed on the upper surface of the second elevation member 52 provided with the first sensor unit 110. The thickness of the unit cushion member installed in each unit lift unit 50 may vary depending on the installed position.

A second lifting and lowering unit 60 for lifting the second lifting member 52 is installed on the inner side of the inner housing member 51. The second lifting and lowering drive unit 60 includes a drive motor 61 installed on the inner circumferential surface of the inner housing member 51 and a lead screw 62 installed on the rotary shaft of the drive motor. A feed member (63) guided by the inner housing member (51) is screwed to the lead screw (62). And a spring 64 is provided between the conveying member 63 and the second elevating member 52 to support the second elevating member 52 with respect to the inner housing member 51 so as to have an elastic force in the vertical direction. The conveying member 63 is prevented from rotating by the inner housing member 51 and is guided in the ascending / descending direction. For this purpose, the hollow formed in the inner housing member 51 may have a polygonal cross-section, and the transfer member 52 may have the same structure as the hollow cross-sectional shape. A separate guide rail may be formed in the interior of the inner housing member in the longitudinal direction so that the conveying member 63 can be raised and lowered without rotating with respect to the inner housing member 51. [

As shown in FIG. 7, a sheet is installed at the ends of the first elevating member 23 or the second elevating member 52 of each of the unit elevating units 20 and 50 so that the first elevating member 23 or The second elevating member 52 can be operated without being exposed, thereby realizing a mattress that can be interconnected.

The electromagnet 42 and the driving motor 61 may be controlled by the control unit 100, respectively. The controller unit 100 includes a first sensor unit 110 installed on the upper surface of the first elevation member 23 or the second elevation member 52 and a second sensor unit 120 installed on the torso of the user, The electromagnet 42 or the drive motor 61 is controlled.

The first sensor unit 110 may be a pressure sensor that measures the pressure applied to the upper surface of the first elevation member 23 or the second elevation member 52 by the weight of the pressure sensor. The second sensor unit 120 attached to the affected part of the patient may be a proximity sensor, a pressure sensor, or the like.

Hereinafter, the operation of the oversized mattress assembly having the automatic back pressure control device according to the present invention will be described.

The mattress assembly of the present invention is capable of supporting the entire body as shown in Fig. 1 or installed on a part of a general mattress as shown in Fig. 8, that is, positioned so as to be located at a position corresponding to the affected part of the molten metal.

And a second sensor is attached to the affected part of the molten metal as shown in FIG.

In this state, when the user lays down or rests on the mattress, the unit mattress member 200 installed on the upper part of the unit lift unit 20, 50 is compressed and supports the body of the molten metal. In addition, the first lifting member 23, which can be lifted and lowered relative to the housing member 21, is lowered while the elastic spring 22 is compressed, thereby supporting the respective parts of the body. As described above, the unit mattress member and the spring are compressed corresponding to the bending of the body, so that the body of the molten metal can be supported in the best state.

In the process of supporting the body of the user as described above, the control unit 100 applies the unit lift unit 20 (50) corresponding to the second sensor unit 120 by the first sensor unit 110 The pressure is detected.

When the pressure sensed by the first sensor unit 110 is equal to or higher than the set pressure, the control unit 100 drives the first lift driving unit 40 or the second lift driving unit 60, (23) or the second elevating member (52). That is, in the case of the first lifting and lowering drive unit 40, by decreasing the intensity of the magnetic force by adjusting the current value for generating the magnetic force in the electromagnet 42, the repulsive force with the permanent magnet 41 can be reduced, The magnetic poles of the electromagnet 41 and the electromagnet 42 are different from each other to weaken the downward or upward elastic support force of the elevating member. In the case of the second elevation driving unit 60, the driving motor 61 is driven to rotate the lead screw 62 connected to the second elevation driving unit 60 to lower the screwed conveyance member 63, Thereby weakening the supporting force by the spring 64. [ As described above, the lowering or supporting force of the elevating member is weakened or the supporting force of the unit elevating unit 50 supporting the ring provided with the second sensor portion is relatively weakened or eliminated. The pressure applied to the affected part is sensed by the first sensor part 110 provided on the second elevation member 52 of the first elevation member 23, and the sensed signal is detected by the control part, So as to control the first elevation driving unit 60 or the second elevation driving unit 60.

 Therefore, it is possible to prevent the inconvenience of the molt and the blood circulation in the affected part from occurring smoothly, which may be caused by a severe pressure acting on the affected part. In particular, it can be fundamentally prevented that the affected part of the molar is immediately after the operation is performed, or the treatment is delayed due to the body load applied to the site where the pressure ulcer is generated.

Meanwhile, the control unit 100 can control the unit lift units supported on the base frame 11 individually according to the contact area of the body, thereby varying the supporting force according to the body part. In this case, It is possible to selectively control the unit lift units 20 and 50 provided in the base frame 11 so as to vary the body support force of the user or oil fuel depending on the region.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.

The buccal mattress assembly provided with the automatic back pressure regulating device of the present invention is widely applicable to various mattresses capable of supporting the body of the bad mattress bed and the bad mattress.
