Abstract

A medical bed has developed, comprising a lifting unit extended to the lower body unit with an insertion unit mounted on an elastic spring for applying pressure to a lifting member, a water collection unit positioned at inner room of the bed frame forming sloped bottom surface, an angle adjustment unit installed at the bed frame for angular movement of the bed frame, a plural of the loess bed units, a separation preventing unit for preventing separation of the loess bed unit and a support plate for supporting the loess bed unit. The body unit extends the lower head unit and guides vertical movement of the loess bed. The lifting member installed on a fastening bar for controlling the lifting unit. The elastic spring is arranged inside of the lifting member, and an inlet-outlet for injecting and discharging pneumatic and hydraulic pressure formed at the upper lifting member.

Claims

1. A medical bed comprising:

a bed frame defining an interior space, the bed frame being provided with legs each having a moving roller, a plurality of loess bed units, and separation preventive members provided at opposite lateral sides thereof to prevent separation of the loess bed units;

a support plate installed to each of the loess bed units to support the loess bed unit;

an upward or downward moving unit including a head portion attached to the support plate, a body portion extending downward from the head portion to guide upward or downward movement of the loess bed unit, and a seating portion provided at a lower end of the body portion so as to be seated on an elastic spring to apply pressure to the interior space of a lifting member, the upward or downward moving units being installed to the bed frame at a predetermined height from a bottom plane;

the lifting member fastened to a fixing die to vertically move the upward or downward moving unit and configured to receive the elastic spring therein, the lifting member having an inlet hole formed at an upper position thereof through which hydraulic fluid is introduced into or discharged from the lifting member;

a water collection unit located in the interior space of the bed frame and including a bottom plate inclined by a predetermined angle, the water collection unit being provided with wheels at four corners of a lower surface thereof; and

an angle adjustment unit installed to the bed frame to enable angular movement of the bed frame.

2. The medical bed according to claim 1, wherein a rail unit is further installed in the interior space of the bed frame to guide sliding of the wheels of the water collection unit.

3. The medical bed according to claim 1, wherein the bed frame is further provided with a bath curtain.

4. The medical bed according to claim 1, wherein the bed frame is further provided with a blowing fan to facilitate blood circulation of the patient.

5. The medical bed according to claim 1, wherein some of the loess bed units, which are located in a central region of the bed, centrally define an opening provided with a supporting rim portion, and a loess cover is inserted into the opening to close the opening.

6. The medical bed according to claim 1, wherein:

the bed frame is further provided with a wash water feed device; and

the wash water feed device includes a supporting pedestal provided at a lower surface thereof with wheels, a vertical post extending upward from an upper surface of the supporting pedestal and provided at a certain position thereof with a shelf, an operating lever installed to an upper end of the vertical post to control the rate at which hot and cold water is supplied thereto, a shower member having a connection hose received in the vertical post to receive water from an external source, the shower member being extended outward from the operating lever so as to inject water from the connection hose, a storage container installed to the vertical post and configured to receive a predetermined level of wash water in an interior space thereof, and an injection hose to inject the wash water from the storage container.

7. The medical bed according to claim 1, wherein the lifting member is further provided with an electronic valve to control introduction of a hydraulic fluid into the lifting member, a pump to introduce the hydraulic fluid stored in a hydraulic fluid device into the lifting member, a controller to control opening/closing operations of the electronic valve and operation of the pump, and a timer to send a control signal to the controller at a predetermined time interval.

8. The medical bed according to claim 1, wherein each of the loess bed units is covered with a waterproof cover.

9. The medical bed according to claim 1, wherein a water discharge hole is perforated at an end position of the water collection unit.

10. The medical bed according to claim 1, wherein the angle adjustment unit includes a cylinder installed to the bed frame and provided with a piston rod, a link having one end coupled to the piston rod via a first hinge and the other end coupled to the bed frame via a second hinge, a supporting frame to support the link, the supporting frame internally defining a space in which a bearing is slidably installed at a position adjacent to the piston rod, and a third hinge installed to a surface of the bed frame to enable angular movement of the bed frame.

11. A medical bed comprising:

a bed frame defining an interior space, the bed frame being provided with legs each having a moving roller, a plurality of loess bed units, and separation preventive members provided at opposite lateral sides thereof to prevent separation of the loess bed units;

a support plate installed to each of the loess bed units to support the loess bed unit;

an upward or downward moving unit including a head portion attached to the support plate, a body portion extending downward from the head portion to guide upward or downward movement of the loess bed unit, and a pressure portion provided at a lower end of the body portion to apply pressure to the interior space of a lifting member, the upward or downward moving units being installed to the bed frame at a predetermined height from a bottom plane;

the lifting member fastened to a fixing die to vertically move the upward or downward moving unit and having inlet holes formed at upper and lower positions thereof, through which hydraulic fluid is introduced into or discharged from the lifting member;

a water collection unit located in the interior space of the bed frame and including a bottom plate inclined by a predetermined angle, the water collection unit being provided with wheels at four corners of a lower surface thereof; and

an angle adjustment unit installed to the bed frame to enable angular movement of the bed frame.

12. The medical bed according to claim 11, wherein a rail unit is further installed in the interior space of the bed frame to guide sliding of the wheels of the water collection unit.

13. The medical bed according to claim 11, wherein the bed frame is further provided with a bath curtain.

14. The medical bed according to claim 11, wherein the bed frame is further provided with a blowing fan to facilitate blood circulation of the patient.

15. The medical bed according to claim 11, wherein some of the loess bed units, which are located in a central region of the bed, centrally define an opening provided with a supporting rim portion, and a loess cover is inserted into the opening to close the opening.
