[0002] A medical care bed is a bed for facilitating the care of patients, mainly used in hospitals. Existing care beds are divided into electric care beds and manual care beds. After treatment, most patients need to stay in the hospital for observation for a period of time, and during this period, patients need to rest on the care bed.

[0003] Since patients need to stay in bed for a long time, the back muscles are prone to become tense, resulting in muscle spasms and stiffness, and may also cause pressure sores. The common practice is for nursing staff to turn the patients over regularly to help them move, which is quite laborious. For these patients who cannot take care of themselves, when they need to be transferred to an operating table or a regular hospital bed, they are usually carried by nursing staff. Carrying patients, especially those with limited mobility and heavy weight, will cause great physical exertion to nursing staff. Long-term or frequent carrying may lead to muscle fatigue and excessive joint burden of nursing staff, increasing their risk of injury. To solve the above problems, a medical care bed and a using method thereof are proposed. Summary of the Invention

At the same time, the third motor drives the third threaded rod to rotate, the threaded block is threadedly connected to the third threaded rod, and the left side of the threaded block is slidably connected to the limit rod. When the third threaded rod rotates, the threaded block will reciprocate in the front and back directions under the guidance of the limit rod, and the patient's back is massaged through the reciprocating motion of the massage cover and the sliding sleeve; S2: When it is necessary to transfer the patient to another hospital bed, start the first motor. The first motor drives the first threaded rod to rotate. The moving block threadedly connected to the first threaded rod will move left and right on its surface as the threaded rod rotates. Since the bottom of the moving block is fixedly connected to the top of the cross beam, and the cross beam is connected to the connecting bar through the mounting strip, and the connecting bar is fixed to the crank, the movement of the moving block will drive the crank to rotate around its connecting shaft with the mounting shell.

The second synchronous pulley is fixed to the right end of the rotating rod, so that the rotating rod rotates. The gears at the left and right ends of the outer surface of the rotating rod rotate with the rotating rod. The gears mesh with the racks, driving the extension rod to move back and forth along the limiting strip to adapt it to the target hospital bed; S4: Start the fifth motor. The fifth motor drives the second rotating roller to rotate. The second rotating roller drives the first rotating roller, the third rotating roller, the fourth rotating roller and the fifth rotating roller to rotate synchronously through the conveyor belt. When the conveyor belt is lengthened, the fifth rotating roller will drive the mounting block to slide on the outer surface of the sliding rod, thereby squeezing the return spring to lengthen the length while ensuring the tension of the conveyor belt, and moving the patient above the conveyor belt to directly above the target hospital bed. When it is necessary to place the patient above the target hospital bed, the output shaft of the fifth motor continues to rotate, while the output shaft of the fourth motor rotates in reverse to retract the extension rod into the bed frame. At this time, the patient and the target hospital bed remain stationary, and as the extension rod is retracted until the patient lands on the target hospital bed.

[0014] Compared with the prior art, the advantages of the present invention are as follows: 1. By setting the lifting assembly and the transfer assembly, after using the lifting assembly and the transfer assembly, the nursing staff does not need to manually carry the patient. For critically ill patients or patients with a large body weight, it can significantly reduce physical consumption, avoid heavy physical labor. Using the lifting assembly and the transfer assembly can provide stable support for the patient, ensure the correct body position of the patient during the transfer process, help prevent muscle strains or fractures caused by improper postures, and can ensure that the patient is transferred in a stable and non-impact manner, greatly reducing the patient's psychological pressure and fear, and can significantly improve their comfort.

[0015] 2. By setting up a massage component, the present invention can help stimulate blood circulation. Especially for those patients who have been bedridden for a long time, back massage can promote blood circulation in the body, reduce blood stasis, thereby improving the transportation of oxygen and nutrients, helping to repair tissues and accelerate the recovery process. The massage component can automatically massage the patient's back, reducing the frequency of manual assistance by caregivers to move the patient, relieving muscle tension in the patient's back, reducing the risk of pressure sores, while reducing the work intensity of caregivers, and can also relieve the patient's pain, alleviate discomfort, and improve comfort.

9. A method of using a medical care bed, for implementing a medical care bed as described in claims 1-8, characterized in that, Including: S1: When massaging the patient's back, first drag the patient above the massage component (7), start the second motor (704), the output end of the second motor (704) drives the second threaded rod (703) to rotate. The bottom of the mounting plate (705) is threadedly connected to the second threaded rod (703) through a threaded seat, and the mounting plate (705) is slidably connected to the sliding guide rail (702) through a sliding block. When the second threaded rod (703) rotates, the mounting plate (705) will perform a reciprocating motion in the left-right direction along the sliding guide rail (702). At the same time, the third motor (713) drives the third threaded rod (710) to rotate. The threaded block (711) is threadedly connected to the third threaded rod (710), and the left side of the threaded block (711) is slidably connected to the limiting rod (709). When the third threaded rod (710) rotates, the threaded block (711) will perform a reciprocating motion in the front-back direction under the guidance of the limiting rod (709). The back of the patient is massaged through the reciprocating motion of the massage cover (706) and the sliding sleeve (712). S2: When it is necessary to transfer the patient to another hospital bed, start the first motor (612). The first motor (612) drives the first threaded rod (610) to rotate. The moving block (611) threadedly connected to the first threaded rod (610) will move left and right on its surface as the threaded rod rotates. Since the bottom of the moving block (611) is fixedly connected to the top of the cross beam (609), and the cross beam (609) is connected to the connecting strip (607) through the mounting strip (608), and the connecting strip (607) is fixed to the crank (604), the movement of the moving block (611) will drive the crank (604) to rotate around its connecting shaft with the mounting shell (601). The top of the crank (604) is rotatably connected to the bottom of the connecting rod (5) through a rotating shaft, thereby realizing the lifting of the bed frame (1). After adjusting to the appropriate height, the patient is pushed above the transfer assembly (8). S3: The output end of the fourth motor (807) drives the first synchronous pulley (808) to rotate. The first synchronous pulley (808) drives the second synchronous pulley (809) to rotate through a synchronous belt. The second synchronous pulley (809) is fixed to the right end of the rotating rod (804), so that the rotating rod (804) rotates. The gears (805) at the left and right ends of the outer surface of the rotating rod (804) rotate with the rotating rod (804). The gears (805) mesh with the racks (803), driving the extension rod (802) to move back and forth along the limiting strip (801) to adapt it to the target hospital bed. S4: Start the fifth motor (821). The fifth motor (821) drives the second rotating roller (813) to rotate. The second rotating roller (813) drives the first rotating roller (812), the third rotating roller (814), the fourth rotating roller (815) and the fifth rotating roller (820) to rotate synchronously through the conveyor belt (822). When the conveyor belt (822) is lengthened, the fifth rotating roller (820) will drive the mounting block (818) to slide on the outer surface of the sliding rod (817), thereby squeezing the return spring (819) to lengthen the length while ensuring the tension of the conveyor belt (822). The patient above the conveyor belt (822) is moved directly above the target hospital bed. When it is necessary to place the patient above the target hospital bed, the output shaft of the fifth motor (821) continues to rotate, while the output shaft of the fourth motor (807) rotates in reverse, retracting the extension rod (802) into the bed frame (1). At this time, the patient and the target hospital bed remain stationary. As the extension rod (802) is retracted, the patient finally lands on the target hospital bed.
