The present invention relates to a backrest of the bed used by patients with uncomfortable behavior, and in the bed frame divided into multiple stages according to the structure of the human body, the backrest is divided into two sides along the longitudinal direction, and a single actuator at the bottom thereof. The divided backrests can be individually adjusted upward angle to prevent bedsores and artificial exercise functions, so that the angle of the divided backrest can be adjusted to improve the disease while improving the therapeutic effect It is about.

In general, the bed used for a patient who is inconvenient to move has a structure in which the back of the patient is angled upward to provide convenience in use.

Separately, the mattress located on the leg of the patient is configured to be angled upward by manual operation or electric driving force.

Therefore, the patient who is uncomfortable to move up one side of the mattress to watch TV or to read and relax, the angle adjustment structure of the mattress is made by the lifting and lowering of the screw shaft by the rotation of the drive motor, the patient himself By controlling the operation time of the drive motor, it is designed to be used conveniently by adjusting it to the desired angle.

In addition, the lower one side of the patient bed as described above is configured to be able to adjust the angle by the manual operation as well as the angle adjustment by the drive motor as described above, but in the near-in manual operation that can not be adjusted by the patient himself Due to the inconvenience, it is common to adopt a bed having an automatic angle adjusting structure.

However, the angle adjusting structure of the patient bed as described above simply adjusts the angle by rotating only one side of the mattress upward, so that it does not correspond to the physical structure of the patient and feels uncomfortable after a certain time of use, due to the driving motor. Noise is induced and is not suitable for psychological stability or sound-sensitive patients.

In particular, when the patient wants to move out of bed, the lower body of the patient still stays on the upper side of the bed, so there is a problem in that it requires excessive movement to the patient who is uncomfortable.

In addition, if the patient simply rests by raising the upper body, the lower body of the patient is located horizontally on the bed, so when maintaining this state for a long time, there is an inconvenience in feeling blood circulation or leg numbness.

Therefore, as in 2004 Patent Application No. 48784 issued by the applicant of the present invention, by dividing the bed frame into a plurality of divided by the actuator to adjust the respective angle, thereby adjusting the upward angle of the user's backrest mattress Of course, the rotation of the frame divided into the patient's thighs, calves and ankles allows the patient's lower body angle to be adjusted, allowing the patient to rest in a more comfortable posture while adjusting the angle of the various mattresses while lying in bed. It is possible to maintain the most stable state according to the condition, and if the patient wants to move out of the bed of the patient bed having the effect that the angle of the mattress in the form of a complete chair can be moved or lie down more easily from the bed. Frame sphere for mattress angle adjustment Joe proposed.

However, the patient bed having the frame structure as described above has a split frame structure that allows the patient's body to move freely, while allowing convenient use of the bed while having a feature of relaxing and reading. ,

Since the backrest is flat, the patient's weight is continuously applied to the patient's back and the sweat and water are smoothly discharged and the air is circulated. There is a problem that the bedsores occur because it does not fall.

When such pressure sores occur, the skin is crushed and therefore requires secondary treatment, and the patient and the caregiver must bear the corresponding pain and effort.

In addition, in the case of severely disabled patients, the patient is unable to move the body for a long time and is kept in a bed, so that the overall mobility of the body is reduced and the functionality of various joints is deteriorated.

In particular, in this regard, as in the Utility Model Registration No. 401864 issued by the applicant of the present invention, the bed frame can be easily lifted up and down, as well as the upper plate and the upper plate frame supporting the upper plate. By the angle adjustment and divided rotation by a separate actuator,

Free up and down of the bed frame allows the patient's body to be cleaned more conveniently, while the patient's body is more comfortable by the operation of the upper plate which can be dividedly rotated without forcing or rotating the patient's body. It is possible to change the position and direction of the bath, and after the bath bed is used, the entire upper plate can be tilted to one side so that the top plate and the bed can be washed more easily, so that the patient's hygiene management is very easy. A private bed was proposed.

However, the bath-only bed as described above is configured such that the divided top plate frame is rotated by the actuator, but the bath-only bed is used only as a bed temporarily used by the patient to take a bath, so that the purpose of hospital bed, etc. It is a structure that cannot be used as a patient bed to be used as, and furthermore, since it does not have a plurality of divided frame structures, the function as a patient bed made of the divided frame cannot be performed.

In addition, the actuator for allowing the upper frame of the bath bed is rotated is individually mounted to the lower side of the upper frame, so that the increase in manufacturing costs, as well as the increase in weight and difficult to carry and maintain, management .

The present invention has been made to solve the problems described above, and divided into the back portion of the patient bed in the longitudinal direction on both sides, and one side of the divided backrest portion hinged on the bed frame to face each other, the division By lower coupling the operating rod having a hinge shaft and a long hole in the lower part of the backrest, respectively, by simultaneously forming the oblique inclined coupling to a single actuator operating shaft,

When the actuator advances, only one side of the backrest is rotated upward by the power transmission of one side working rod, and when the actuator moves backward, only the other side of the backrest is rotated upward by the power transfer of the other side working rod. The individual rotation of the divided back portion to rotate the upper body of the patient to pressure distribution, ventilation, and water discharge is to be prevented, sore bedsores are prevented. It is an object of the present invention to provide a patient bed capable of adjusting the angle of the divided backrest can expect an improvement effect.

Hereinafter, preferred embodiments of the present invention will be described.

The upper frame of the bed frame 100 and the backrest 10 and the thigh portion 30, the shin portion 40, the footrest divided into a frame 50 respectively divided by hinges, each of these frames are rotated by the actuator In a known patient bed that is bent,

The backrest is divided into two parts in the longitudinal direction of the bed frame 100, and the opposite side ends of the divided backrest parts 10 and 10 'are hinge-fixed to the fixing table 101 in the center of the bed frame 100. ,

The lower end of the divided backrest portion 10 (10 ') is coupled to the front end is hinged and the lower end mounting rods 12, 12' having a long hole (11, 11 '), respectively,

The front end is hinged to the lower portion of the fixing base 101 and the lower mounting the rotating bracket 103 is inserted into the fixing pin 102,

A pedestal 104 is formed on the fixing base 101 to support the bottom of the divided backrest portions 10, 10 ′, and the lower side of the pedestal 104 faces the inside of the bed frame 100. At the end of the operating shaft 111 of the mounted actuator 110, the long holes 11, 11 'of the operating rods 12, 12' and the fixing pins 102 of the rotating bracket 103 are simultaneously fastened. In accordance with the appearance of the working shaft 111, the backrest 10, 10 'is configured to rotate up and down, respectively.

When described in more detail by the accompanying drawings the operation of the patient bed capable of adjusting the angle of the present invention divided backrest by the above configuration as follows.

As is well known, the patient bed of the present invention is capable of more convenient activity of a patient who is uncomfortable with each frame part divided into a plurality of upper side of the bed frame 100, and the frame part supports the upper body of the patient. 10 is divided into the shin portion 40 for supporting the calf of the patient and the footrest 50 for supporting the ankle and the foot of the patient, respectively.

Each of the divided frames is hinged to the opposite side opposite to each other, is rotated in the up and down direction by the operation of a separate actuator (not shown in the figure) is to bend and unfold in the direction intended by the patient. .

However, the problem that the pressure sores caused by the pressure of the weight applied to the back of the patient also arises in such a patient bed, the present invention is applied to the configuration for preventing the bedsores.

That is, the backrest portion is divided into two sides in the longitudinal direction to form the backrest portions 10 and 10 'divided into left and right portions, respectively.

Such a backrest 10 (10 ') has a structure in which one end is hinged to the fixing base 101 across the middle of the bed frame 100 and the other side is mounted on the bed frame 100 As it is, the backrest portion 10, 10 'can be rotated only upward by using the hinge point as the axial point.

The lower end of the backrest portion 10 (10 ') has a working rod 12 (12') is hinged to the front end is formed, the lower end of the operating rod 12, 12 'is a long hole 11 (11 ') is formed.

In addition, the lower portion of the fixing frame 101 of the bed frame 100 is a rotary bracket 103 having a fixing pin 102 at the bottom is mounted downward by the hinge connection of the front end, of the bed frame 100 A pedestal 104 is formed at one side to support the bottom of the divided backrest portions 10 and 10 'and the pedestal 104 is connected to the fixing base 101, and an end of the pedestal 104 is formed. On the lower side, the end portion of the actuator 110 is hinged toward the fixing base 101.

In this state, the end of the operation shaft 111 of the actuator 110 is inserted into the fixing pin 102, and the fixing pin 102 has a long hole 11 of the operation rods 12 and 12 '. ) 11 'are inserted into each other so as to be inserted at the same time.

In addition, in the state in which the backrest part 10, 10 'is completely unfolded in a flat state, the backrest part 10, 10' must have a length and a coupling structure in which the fixing pin 102 is located at the top of the long hole 11, 11 '. It is.

Therefore, as shown in FIG. 4A, when the actuator 110 operates and the operating shaft 111 is advanced, the fixing pin 102 and the rotating bracket 103 are rotated to one side. As the 102 rotates, the long hole 11 of the one-side operation rod 12 is pushed up and its kinetic force is eventually converted into the power to rotate the backrest portion 10 of one side upward.

At this time, since the fixing rod 102 is moved to the lower side of the long hole 11 ', the other operation rod 12' does not transmit any momentum to the operation rod 12 ', so the other backrest 10' Will not flow.

After the rotation of the backrest part 10 is made by such an operation, when the operating shaft 111 of the actuator 110 is reversed as shown in FIG. 4B to reach the original position, the backrest part of one side that has been rotated ( 10) is returned to its original position.

In addition, when the operation shaft 111 is continuously retracted from this time, since the fixing pin 102 acts to push up the long hole 11 'of the operation rod 12' of the other side, the backrest 10 described above. Without the interference of the other side of the back portion (10 ') is to perform the upward rotation movement.

Therefore, the backrest part 10 (10 ') divided by only a single actuator 110 operation can be repeatedly rotated upward and return, and the backrest part is divided in the longitudinal direction according to the body of the patient, respectively 10) (10 ') is to prevent pressure sores as much as possible by dispersing or shifting the weight or pressure applied to the lower dorsal side in case of a patient or a critically ill patient.

In particular, by adjusting the operating distance of the actuator 110 or by setting the operating time, such as to have a more smooth exercise force or automatic operation according to the time can be used more convenient, the patient with little exercise power Forced movement is made to them to prevent the various joints and the like to be helpless.

Such a patient bed of the present invention is not shown, but it is common to use a separate mattress on the upper side of the bed frame 100.

As described above, the patient bed capable of adjusting the angle of the divided backrest part allows only one side of the backrest part to be rotated upward by power transmission of one side actuating rod when the actuator moves forward, and the other side actuating rod when the actuator moves backward. Only the other part of the backrest is rotated upward by the power transmission, and by rotating the upper part of the patient by the individual rotation of the backrest of the patient, pressure distribution, ventilation, and water discharge are made, which prevents bedsores and artificially forced movement. Through imparting motility to the patient's joints will be able to expect more excellent therapeutic effect and improvement.
