Description

[Detailed Description of the Invention] The present invention relates to a medical buoyancy generating device.

For example, when transporting a critically ill patient who is bedridden or a patient with physical disabilities who is unable to get up or walk on their own from a hospital bed to a treatment room or treatment room,
Usually two or three nurses lift the patient's body and transfer it to a stretcher or wheelchair, but this work is hard work that requires considerable strength, causing problems such as back pain for the nurses. .

Taking the above points into consideration, the present invention provides a medical buoyancy generating device that facilitates the movement of a patient from a bed to a stretcher car or wheelchair, and also allows the patient to be easily moved between hospital rooms or wards. The purpose is to

Embodiments of the present invention will be described below with reference to the drawings.
In Figures 1 to 3, reference numeral 1 denotes a portal-shaped beam 2, each of which is a support frame with wheels (casters) 3 installed at the bottom thereof, and a ball bushing case in which a ball bushing 4 is housed in the upper part of each support frame 2. 5 is installed.
Reference numeral 5a denotes a locking nut that is screwed onto the ball bushing case 5 to prevent the ball bushing 4 from popping out. Each vertical portion 6 of the beam 1 has a respective stopper dot 5a,
It is inserted into each ball bushing 4 and each ball bushing case 5 so as to be vertically slidable. 2a is each support member attached to each support frame 2, 7 is each ball screw shaft rotatably supported by each support member 2a via each bearing 2b, and each ball screw shaft 7 is connected to each vertical It is screwed into each ball screw nut part 6a integrally connected to the lower part of the part 6, and is inserted into each vertical part 6 so as to be movable in the vertical direction. A ball 8 is interposed between the ball screw shaft 7 and the ball screw nut portion 6a. Reference numerals 9 and 10 denote motors and speed reducers respectively attached to each support frame 2, and each motor 9 is connected to each ball screw shaft 7 via a speed reducer 10, respectively. 1 is a running part supported on the horizontal part 12 of the support 1 via a running car 11a, 13 is a hook block suspended from the running part 11 via a rope 14, and 15 is attached to one support frame 2. With the attached free hoist, one end of the rope 14 is fixed to the column 1 and suspends the hook block 13 via a pulley 16, and the other end of the rope 14 is attached to the pulley 17 attached to the column 1.
It is wound around the drum of the free hoist 15 via. Furthermore, as shown in FIG. 4, the free hoist 15 includes a motor 18, a reducer 19 connected to the motor 18, and a drum 20 around which the rope 14 is wound.
It includes an electromagnetic clutch 21 provided between the reducer 19 and the drum 20, a brake 22 connected to the drum 20, and a load detector 23 for detecting the load suspended on the hook block 13. The detection signal is applied to the excitation winding 21a of the electromagnetic clutch 21 via the control section 15a, and the electromagnetic clutch 21 generates a torque commensurate with the torque generated in the drum 20 due to the load, thereby supporting the load in a weightless state.

In the above device, a portal beam 1 is installed on the floor across the bed 24 and the stretcher car 25 or wheelchair,
The patient on the bed is suspended from the hook block 13 via appropriate equipment, and the free hoist 15 is activated to support the patient in a weightless state. Thereafter, the nurse moves the patient up and down with a slight force and also runs the traveling section 11 to transfer the patient from the bed 24 to the stretcher car 25 or wheelchair. It is also possible to move the beam 1 between hospital rooms or wards by moving the beam 1 via the wheels 3 while the patient is suspended in a weightless state on the foot block 13. 1 must be lowered. In this case, the ball screw shaft 7 is rotated by the rotation of each motor 9, and each vertical portion 6 of the column 1 is moved downward. After moving to the hallway or hospital room, each motor 9 is rotated in the opposite direction to raise the height of the beam 1 again to facilitate movement of the patient.

As described above, in the present invention, each vertical part of the portal beam is supported by each support frame so as to be able to move up and down, and the patient is placed on a hook block that is suspended via a rope from the running part provided on the horizontal part of the pillar. The patient is suspended and supported in a weightless state by a free hoist attached to a support frame, allowing the nurse to transfer the patient from the bed to a stretcher or wheelchair with little force. Furthermore, since wheels are provided at the bottom of the support frame, the device can be moved while suspending the patient in a weightless state. Moreover, since the beam can be moved up and down by the rotation of the motor attached to the support frame, by lowering the height of the beam when going in and out of the hospital room, it is possible to move in and out of the hospital room without any hindrance. Or they can be easily moved between wards.
