A patient bed generally used in a hospital is provided with a lifting stand 2 on both sides of the bed frame 1 as shown in FIG. 1, and an upper mat and a lower mat on the inside of the bed frame inside the hanger 2. The mattress 3 is separated and refracted is installed, and a lifting device (not shown) for adjusting the refraction angle of the mattress 3 is provided on the bed frame under the mattress, and the lifting device is provided with a handle 4 provided under the bed. ) Is driven by operation.

In addition, the patient bed is provided with a reading table 5 on the bed frame to be rotated by 90 ° so that it can be used as a reading or a table.

Such a conventional patient bed has the advantage of greatly improving the discomfort for the patient, but there are still a lot of areas that need to be improved for the critically ill patients who can not freely change their position because of uncomfortable or impossible behavior.

In more detail, there is a serious patient who can not change their position on the bed because of the inconvenience or impossibility of the movement of the patient, even if there are people who are free to move. Among the above-mentioned critically ill patients who are unable to behave at all, all of them are lying on the bed, and when they are prolonged in a supine position, they are accompanied by pain in the back part, especially bone exposed areas, when they are prolonged by weight. Bed sores (decubitus) may occur. This can lead to complications and rehabilitation of patients who are able to recover for a long time, and the patients themselves have to endure great pain as well as the great pain of the caregiver.

Such pressure ulcers are serious illnesses that can be difficult to cure and involve considerable pain unless they are corrected in the same posture, and can seriously lead to loss of life. Therefore, in the case of severely unable to move, the caregiver should check it frequently and change the patient's position periodically to release the stressed area.

However, in the existing bed structure as described above, it is possible to change the position of the patient in a sitting position in the lying posture, there is a limitation that cannot be changed in other positions. Therefore, at least two or more adults had to periodically change the position of the patient directly to prevent bedsores, so care must be taken with care, and it is very difficult to change the posture by personnel without affecting the patient. There is a problem that can cause another pain, requiring more careful attention.

The present invention is to solve the above-mentioned problems, by installing a pair of opposite beds in a circular angle inside so as to be rotatable to switch the position of the patient lying on the bed by the rotation of the bed, The goal is to provide a swivel medical bed that can change the position of the patient more easily and periodically without the help of a caregiver, thereby preventing diseases such as pressure sores that may occur in long-term bed life. .

According to an embodiment of the present invention for achieving the above object, a vertical angle of a bearing form consisting of an inner ring and an outer ring are respectively installed in the vertical frames of both sides of the bed for supporting the bed, the inner ring of the circular angle is It is connected to the movable shaft on the horizontal frame that connects the vertical frames, and is rotated by the operation of the movable shaft. At least two lead screws each having a left screw right screw formed on the center of each circular angle are mediated through the bearing. The lead screw is rotatably mounted up and down by a ball nut fitted with a pair of beds facing up and down inside the circular angle on the lead screw. This drive is connected to drive means provided on the outer surface of any one of the beds of the pair The rotary medical bed configured to be able to lift the bed of the pair and at the same time through a single rotation is provided.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a perspective view showing the overall configuration of a rotary medical bed according to an embodiment of the present invention, Figure 3 is a schematic perspective view showing the main configuration of the present invention, Figure 4 is a front view of the present invention according to FIG.

As shown in FIGS. 2 to 4, the pair of opposing circular angles 20 installed on the vertical frames 10a at both ends of the frames for supporting the bed and the respective circular angles 20 are provided. At least two lead screws 40 installed upright inside the bed, beds 50a and 50b mounted on the lead screw 40 in a circular angle 20 so as to be liftable, and the lead screws 40 It consists of a drive means 60 for driving.

The circular angle 20 is in the form of a general rolling bearing in which a roller is interposed between the outer ring 20b and the inner ring 20a, and the outer ring 20b is perpendicular to both sides of the frame of the bed for supporting the beds 50a and 50b. The frame 10a is fixed to the distal end by welding, and the inner ring 20a is connected to the movable shaft 30 on the horizontal frame 10b connecting the vertical frames 10a, as shown in FIG. It is rotated by the operation of. More specifically, gear teeth are formed on the inner diameter of the inner ring 20a, and spur gears meshing with the gear teeth of the inner ring 20a are formed at both ends of the movable shaft 30. Accordingly, the inner ring 20a of each of the circular angles 20 may be simultaneously rotated in the same direction by a rack and pinion driving method by the operation of the movable shaft 30.

The lead screw 40 has a structure in which left and right screws are respectively formed on both sides of the center of the lead screw 40, and both ends of the lead screw 40 may be installed and rotated on the bearing 45 installed on the inner ring 20a of the circular angle 20.

The beds 50a and 50b include a cushion chain mattress (not shown) installed on one surface thereof, and a pair is installed to face up and down inside the circular angle 20. A ball nut 42 is provided on the edges of the beds 50a and 50b, and the ball nut 42 is coupled to the lead screw 40. Accordingly, due to the lifting and lowering of the ball nut 42 due to the rotation of the lead screw 40, the pair of beds 50a and 50b are in close contact with each other in a direction away from each other with their sides supported inside the circular angle 20. Is lifted in the direction.

At this time, the pair of beds (50a, 50b) has a shape in which both sides of the width direction in the longitudinal direction protrudes more than the center portion thereof, the center portion for lying down the patient is recessed outward as shown in FIG. Therefore, when the pair of beds 50a and 50b facing each other in close contact with the patient in the longitudinally lying state in the center portion, the beds 50a and 50b can completely wrap the patient. In addition, the face exposed portion 52 is perforated on one side of the upper bed of the pair of beds. Accordingly, when the pair of beds are in close contact with each other, the user's face is exposed to the outside so that the patient can maintain a smooth breathing.

The driving means 60 is connected to the lead screws 40 inside the circular angle 20 in a state provided on the outer surface of any one of the pair of beds 50a, 50b. These lead screws 40 are rotated simultaneously. The drive means 60 includes a drive motor 62 and may be connected to each lead screw 40 through a belt or chain. As an example, as shown in FIG. 2, a drive motor 62 is installed on a bracket on one side of the inner ring 20a, and a drive sprocket (or belt pulley) 64 is formed at the end of the rotation shaft of the drive motor 62. In addition, the driving sprocket 64 may be connected to a driven sprocket (or belt pulley) 66 and a chain (or belt) 68 which are arranged at the front end side of each lead screw 40. Therefore, the lead screw 40 can be simultaneously rotated forward and reverse by chain transmission (or belt transmission) according to the forward and reverse rotation driving of the drive motor 62.

Here, the drive motor 62 is equipped with a load sensor, the motor immediately stops when a certain load is applied to the motor. That is, when the patient is lying on the lower side bed 50a and the other bed 50b facing each other closely wraps around the patient, the bed 50a, 50b of the bed according to the patient's body shape. There may be a difference in the degree of adhesion, at which time the load sensor is mounted on the drive motor 62 to prevent the pressure applied to the body while wrapping the patient with a constant adhesion at all times according to the patient's body type will be.

Preferably, at least two or more stoppers 54 may be further provided on opposite wing sides of any one of the pair of beds facing each other. Such a stopper is prepared in case the load detection sensor is not operated due to an electrical malfunction, and maintains a constant distance between the bed and the bed when the drive motor is continuously driven due to the malfunction of the load detection sensor as described above. It is to prevent the severe pressure of the patient's body by giving. Such stopper 54 may be configured to be able to adjust the axial length to be able to adjust the separation distance when the pair of beds are completely in contact. In this way, even when the patient's body is different, the distance between the beds can be arbitrarily adjusted when the pair of beds are in close contact with each other so that the distance between the beds can be set so that there is no objection without pressing the patient.

Hereinafter, the operation of the present invention configured as described above will be described in detail.

As shown in FIG. 5A, the patient is lying on the mat of the lower bed 50a among the pair of beds 50a and 50b facing up and down. As such, when a predetermined time elapses while the patient is lying down, the patient feels discomfort in the back part due to the continuous compression by the body load. At this time, the present invention is to change the position of the patient by operating the present invention by operating a switch (not shown) provided on one side (or after a predetermined time elapses according to the timer setting).

Specifically, the driving motor 62 is driven according to the operation command according to the switch operation (or timer setting), and the driving force of the motor is transmitted to each lead screw 40 installed inside the circular angle 20 by chain transmission. To rotate them simultaneously.

Rotation of the lead screw 40 causes the pair of beds 50a and 50b having the ball nut 42 and the ball nut 42 to move up and down while being supported by the lead screw 40. The lead screw 40 ) Is a left-handed right-handed screw formed at the center of the center, so that when the lead screw 40 rotates forward, the pair of beds 50a and 50b are in close contact with each other through the ball nut 42 at the same time. Is moved. Therefore, in a state where the pair of beds 50a and 50b are lifted and in close contact with each other, the pair of beds 50a and 50b completely surround the patient as shown in FIG.

In this state, the inner ring 20a of the pair of opposite circular angles 20 supporting the beds 50a and 50b and the lead screw 40 is movable while being supported by the outer ring 20b as shown in FIG. 6A. When the rotational force of the shaft 30 is transmitted and gradually rotates in one direction and the rotation angle is 180 °, that is, the upper and lower positions of the beds 50a and 50b are stopped. In this state, the patient lying on the beds 50a and 50b also takes the upright position with the back part facing upward. In this state, the lead screw 40 is rotated by the reverse rotation of the drive motor. 6B, the pair of beds 50a and 50b that are in close contact with each other are spaced apart from each other in a direction away from each other.

Therefore, the patient can rest in a state in which the position is switched, and after a certain time, the switch is operated again (or automatically driven by a timer setting), and the beds 50a and 50b are followed in the reverse order. By returning to the original state, the patient is placed on the bed (50a, 50b) as in the original state.

That is, the present invention is the position of the pair of beds (50a, 50b) is reversed due to the rotation of the inner ring (20a) of the circular angle 20, thereby the patient lying down to take a down position or to return to the original position again It can be.

If the above-described operation is repeatedly performed according to the patient's condition, incapacitated patients, who usually spend most of their time lying on the bed, decubitus and decubitus, which are painful in the place where the bone is exposed, The same disease can be prevented in advance.

As described above, according to the rotary medical bed of the present invention, a pair of opposing beds are rotatably installed inside the circular angle, so that the position of the patient lying on the bed by the rotation of the bed is easily without the help of a caregiver. It can be converted, thereby preventing the disease such as bedsores that can occur in long-term bed life in advance.

What has been described above is only one embodiment for carrying out the rotary medical bed according to the present invention, the present invention is not limited to the above-described embodiment, the subject matter of the present invention as claimed in the following claims Without departing from the scope of the present invention, any person having ordinary skill in the art will have the technical spirit of the present invention to the extent that various modifications can be made.
