Abstract

A bedsore prevention mattress is disclosed, which can effectively prevent a bedsore of a patient who uses a bed or the like for a long time by circulating air while raising a portion directly contacting with a back, waist or shoulder of a patient. The bedsore prevention mattress comprises a plurality of air cylinder apparatuses each equipped with a vertically installed cylinder body, a piston rod which is engaged to each cylinder body and moves up and down, and a contact means which is engaged to an upper side of the piston rod and contacts with a patient'"'"'s back; an air supply apparatus for supplying a high pressure air to each air cylinder apparatus; an air supply tube H which connects each air cylinder apparatus and the air supply apparatus; and a control unit C which controls the operations of the air supply apparatus and the air cylinder apparatus.

Claims

1. In a mattress, a bedsore prevention mattress, comprising:

a plurality of air cylinder apparatuses (6) each equipped with a vertically installed cylinder body (2), a piston rod (3) which is engaged to each cylinder body (2) and moves up and down, and a contact means (4) which is engaged to an upper side of the piston rod (3) and contacts with a patient'"'"'s back;

an air supply apparatus (8) for supplying a high pressure air to each air cylinder apparatus (6);

an air supply tube H which connects each air cylinder apparatus (6) and the air supply apparatus (8); and

a control unit C which controls the operations of the air supply apparatus 8 and the air cylinder apparatus (6).

2. The mattress of claim 1, wherein said piston rod (3) of the air cylinder apparatus (6) is formed in a hollow cylindrical shape.

3. The mattress of claim 1, wherein said contact means (4) includes a cap (42) which is engaged to an upper side of the piston rod (3) and is equipped with a plurality of ventilation holes (420), and a flexible pad (44) which is engaged to an outer surface of the cap (42) and is equipped with an upwardly protruded protrusion (440).

4. The mattress of claim 3, wherein said ventilation hole (420) has a lower side getting narrower and an upper side getting wider, so when air is discharged from a lower side to an upper side, an air discharge pressure can increase.

5. The mattress of claim 4, wherein said ventilation hole (420) is formed in a shape arched from a clockwise direction to a counterclockwise direction, so air is discharged in a whirlwind shape.

6. The mattress of claim 3, wherein said pad (44) is made of rubber or silicon and is formed in a donut shape with a through hole in its center, with its upper side being upwardly protruded.

7. The mattress of claim 1, further comprising a through hole (100) formed by punching the portions of the mattress, so that a user can urinate or defecate;

a cover (110) which is engaged to the through hole (100) for opening and closing the same; and

a feces container (140) which is engaged to a lower side of the through hole (100) for receiving feces.
