Description

Technical Field

[0001] The invention relates to the field of auxiliary equipment, and in particular to an auxiliary turning treatment bed for stroke patients. Background Art

[0002] Stroke, also known as apoplexy or cerebrovascular accident, is an acute cerebrovascular disease characterized by high morbidity, high disability and high mortality. It refers to localized ischemic necrosis or softening of brain tissue due to impaired blood supply to the brain, ischemia and hypoxia. Stroke patients often have limb movement disorders. Maintaining the same posture for a long time will cause continuous pressure on the skin in contact with the bed. By turning over regularly, the contact point between the body and the bed can be changed, the pressure on local blood vessels can be relieved, and blood circulation can be restored to normal, thereby preventing ischemia and necrosis of skin tissue caused by blood circulation disorders, and avoiding the formation of pressure sores.

[0003] When turning over, the existing turning mechanism generally only has a lateral hinge-type turning over, which will inevitably cause the patient's body to shift. The patient's body needs to be moved again when it leaves the midline of the bed, which is not conducive to effective treatment of the patient. Summary of the invention

[0004] In order to make up for the above deficiencies, the present invention provides an auxiliary turning treatment bed for stroke patients that overcomes the above technical problems or at least partially solves the above problems.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An auxiliary turning treatment bed for stroke patients, comprising a bed body, a side of which is provided with a turning transmission mechanism;

[0007] The conveying and turning mechanism comprises:

[0008] A square frame, the square frame is arranged on one side of the bed, the front and rear parts of the square frame are both provided with limiting shafts arranged in a linear array, the upper half of the inner circle of the body of the square frame is provided with a first transmission roller through a movable shaft, and the end of the first transmission roller is provided with a second pulley;

[0009] A mounting fixed shaft is arranged at the bottom of the inner circle of the square frame, and first servo motors are arranged on both sides of the mounting fixed shaft. The output shaft of the first servo motor is provided with a first pulley through a connecting member, and the first pulley is connected to the second pulley through a transmission belt;

[0010] A side mounting plate, the other side of the bed body is provided with a side mounting plate, and the side mounting plate is provided with a second transmission roller via a movable shaft;

[0011] A winding roller, the winding roller is movably connected to the legs of the bed through a movable shaft;

[0012] The cut cloth has one side wound around the winding roller, and the other side of the cut cloth passes through the second transmission roller and is wound around the first transmission roller.

[0013] By setting up a conveying and turning over mechanism, when the patient needs to turn over in situ, the cut cloth can be moved like a transmission belt, one side of the stroke patient's body remains stationary, and the other side is held by medical staff. During this process, the human body rotates along the middle part of the body, and the limbs will not be shifted during the turning over process. At the same time, this mechanism is used when the patient is just placed on the bed. The stroke patient who moves sideways is first placed on one side of the top of the bed, and then the patient's body will be conveyed to the middle side of the bed by the cut cloth moving to one side, which greatly saves the workload of the caregiver, and there is no need to move the patient after placing him on the bed. After the patient is placed, the cut cloth can also be cut to serve as a medical blanket and other functions, which is clean and hygienic and conducive to the patient's recovery.

[0017] By setting up a turning mechanism in bed, the outer movable plate on the outside is offset while the inner movable plate on the inside is also translated, preventing the patient's limbs from being clamped by the existing hinge-type turning components. Traditional hinge-type turning components have the risk of clamping the patient's limbs during use, while in the new turning mechanism, the design of the outer movable plate offset to drive the inner movable plate to translate effectively avoids this problem. For patients who are unconscious or cannot control their bodies independently, this greatly reduces the probability of accidental injury caused by turning operations and ensures the patient's physical safety.

[0018] In one embodiment of the present invention, a first hole-opening strip is provided on the front and rear sides of the top of the inner pad, and a second hole-opening strip is provided on the front and rear sides of the outer pad.

A swinging straight groove plate is provided on the side of the pillow block through a movable shaft, and the end of the swinging straight groove is movably connected to the front and rear parts of the outer movable plate through a movable shaft.

[0021] In one embodiment of the present invention, a pulley is provided at the bottom of the outer movable plate, and the bottom of the pulley overlaps the outer side pad.

[0022] In one embodiment of the present invention, a lifting mechanism is provided on the top of the bed, and the lifting mechanism includes columns, and the columns are fixedly connected to the four sides of the top of the bed, the top of the columns is fixedly connected to the lifting columns, the ends of the lifting columns are fixedly connected to the winding plates, the bottom of the lifting columns is fixedly connected to the fixed double-axis plates, a first transmission wheel is provided between the fixed double-axis plates via a movable shaft, a cylinder is provided on the top of the lifting column via a connecting piece, a movable double-axis plate is provided on the bottom end of the cylinder via a connecting piece, and a second transmission wheel is provided between the movable double-axis plates via a movable shaft.

[0023] In one embodiment of the present invention, a rope is provided on the winding plate, and the rope is wound around the second transmission wheel and the first transmission wheel in sequence.

[0025] The invention provides an auxiliary turning treatment bed for stroke patients, and its beneficial effects include:

[0026] 1. By setting up a conveying and turning over mechanism, when the patient needs to turn over in situ, the cut cloth can be moved like a transmission belt. One side of the body of the stroke patient remains stationary, and the other side is held by medical staff. During this process, the rotation of the human body is along the middle part of the body, and the limbs will not be shifted during the turning over process. At the same time, this mechanism is used when the patient is just placed on the bed. The stroke patient who moves sideways is first placed on one side of the top of the bed, and then the patient's body will be conveyed to the middle side of the bed by the cut cloth moving to one side, which greatly saves the workload of the caregiver. There is no need to move the patient after placing him on the bed. After the patient is placed, the cut cloth can also be cut to serve as a medical blanket and other functions. It is clean and hygienic and is conducive to the patient's recovery.

[0027] 2. By setting up a turning mechanism in bed, when the outer movable plate on the outside is offset, the inner movable plate on the inside will also translate, preventing the patient's limbs from being clamped by the existing hinge-type turning parts. Traditional hinge-type turning parts have the risk of clamping the patient's limbs during use, while in the new turning mechanism, the design of the outer movable plate offset to drive the inner movable plate to translate effectively avoids this problem. For those patients who are unconscious or cannot control their bodies independently, this greatly reduces the probability of accidental injury caused by turning operations and ensures the patient's physical safety.

[0028] 3. By setting up a lifting mechanism, the lifting mechanism can lift the lifting cloth. Combined with the turning mechanism on the bed, when the patient is turned over, the lifting cloth can connect the bedding under the patient's body and medical pads and other objects to the patient's body and lift them to a certain length, so as to prevent soft objects from being stuffed into the gaps between parts when the turning parts are moving. Preventing soft objects from being stuffed into the gaps reduces the risk of failure of the turning mechanism, thereby avoiding accidental injuries to the patient caused by mechanism failure, such as being stuck or sudden interruption of the turning action, and ensuring the safety of the patient during the turning process.

[0055] Specifically, the working process or working principle of the auxiliary turning treatment bed for stroke patients is as follows: when in use, if the patient needs to be placed on the bed, the cutting cloth 205 is first passed around the first transmission roller 2023 and connected to the second transmission roller 2031, and the medical staff can first place the patient's body on the outer movable plate 315. At this time, the patient's body is located on the cutting cloth 205, and the first servo motor 2021 is set. Under the transmission action of the first pulley 2022 and the second pulley 2024, the second transmission roller 2031 is turned. The cutting cloth 205 is pulled to one side, and the patient's body will be transmitted to the center of the bed body 1. The cutting cloth 205 can be cut or not. If it is not cut, the patient can be turned over in situ. The cutting cloth 205 can be moved in a belt-like manner. One side of the body of the stroke patient does not move, and the other side is held by the medical staff. During this process, the rotation of the human body is rotated along the middle part of the body, and the limbs will not be offset during the turning process. If a general turning over is required, a second servo motor 313 is set, and the first servo motor 313 is used to rotate the body of the stroke patient. Under the action of the gear 310, the second gear 311 and the third gear 312, the threaded shaft 309 rotates, and under the action of the thread meshing, the first threaded platform 307 moves together with the second threaded platform 308, thereby driving the inner movable plate 314 and the outer movable plate 315 to move. The side of the outer movable plate 315 is connected to the second threaded platform 308, and the middle part is connected to the pillow block 3091 through the swing straight groove plate 316, so the other side of the outer movable plate 315 is pushed up, which is manifested as turning over as a whole. During the turning operation, a cylinder 404 is provided, and the cylinder 404 presses the second transmission wheel 4024 downward, and the end of the rope 4025 is pulled upward, and then the lifting rod 405 pulls the lifting cloth 406 upward, and the lifting mechanism 4 can lift the lifting cloth 406. Combined with the turning mechanism 3 on the bed, when the patient is turned over, the lifting cloth 406 can connect the bedding and medical pads under the patient's body to the patient's body and lift them to a certain length, so as to prevent soft objects from being stuffed into the gap between the parts when the turning parts are moving.
