A medical postoperative rehabilitation multifunctional nursing bed

Abstract

The present invention discloses a medical postoperative rehabilitation multifunctional nursing bed, which relates to the technical field of nursing beds, including a nursing bed, a motor, and a lifting rod. The output end of the motor is connected to a transmission mechanism for driving the lifting rod to move and lift. The present invention sets a transmission mechanism to realize that when the moving seat moves toward the end away from the motor, the lifting rod drives the patient's knee to move upward, so that the patient's legs are bent and exercised. At the same time, the piston rod transports the gas inside the piston cylinder to the air bag belt through the air hose, so that the air bag belt expands and squeezes the patient's calf. When the moving seat moves toward the end close to the motor, the lifting rod moves and resets, and the patient's legs are bent and then straightened on the bed. This reciprocating cycle is repeated. Through the mutual coordination of the above parts, the patient's legs are bent and exercised, and the patient's calf muscles are squeezed and exercised at the same time, thereby improving the efficiency of the patient's leg exercise and saving time and effort.

Description

Technical Field

[0001] The invention relates to the technical field of nursing beds, in particular to a multifunctional nursing bed for medical postoperative rehabilitation. Background Art

[0002] Nursing beds are generally powered beds, which are divided into electric or manual nursing beds. They are designed according to the patient's bedridden lifestyle and treatment needs, so that family members can accompany the patient. They have multiple nursing functions and operation buttons, and use insulated and safe beds. Legs are the basis for people to carry out normal activities. Leg diseases and injuries will affect people's normal work and life.

[0003] After the operation, the patient needs to rest in bed for a long time due to physical weakness and wounds, which makes the legs unable to get enough exercise, which can easily cause leg muscle atrophy. In order to restore normal mobility, the legs need to be rehabilitated. In the prior art, when performing leg exercises on bedridden patients, the patient's legs are usually bent and stretched manually, and the patient's calves need to be massaged, which is labor-intensive, time-consuming and labor-intensive. Based on this, in order to facilitate leg exercises for patients after surgery, a medical postoperative rehabilitation multifunctional nursing bed is proposed. Summary of the invention

[0029] In this embodiment, when in use, the two airbag belts 310 are tied to the two calves of the patient, and the reciprocating screw rod 301 is driven to rotate by the motor 2, so that the reciprocating screw rod 301 drives the moving seat 302 to move back and forth. When the moving seat 302 moves toward the end away from the motor 2, the moving seat 302 drives the two moving rods 303 to move, so that the moving rods 303 drive the lifting rod 304 to move. When the outer wall of the lifting rod 304 contacts the outer wall of the limiting rod 306, the lifting rod 304 moves upward along the outer wall of the limiting rod 306 under the limiting extrusion of the limiting rod 306. When the lifting rod 304 moves upward along the inner wall of the moving rod 303, the lifting rod 304 drives the connecting tube 305 to move upward, so that the connecting tube 305 The lifting rod 10 is driven to move upward, and the lifting rod 10 drives the patient's knee to move upward, so that the patient's legs can be bent and exercised. At the same time, the moving seat 302 drives the piston rod 308 to move, so that the piston rod 308 transmits the internal gas of the piston cylinder 307 to the air bag belt 310 through the air hose 309, so that the air bag belt 310 expands and squeezes the patient's calf. When the moving seat 302 moves toward the end close to the motor 2, the lifting rod 10 is moved and reset, and the patient's legs are bent and then straightened on the bed. This reciprocating cycle is repeated. Through the mutual coordination of the above parts, the patient's legs can be bent and the calf muscles can be squeezed and exercised at the same time, thereby preventing the patient's calf muscles from atrophy due to lack of exercise.

[0030] Please refer to Figure 1 , Figure 5 One end of the airbag belt 310 is connected to a fixing belt, a Velcro hook surface 4 is sewn on the top of the fixing belt, and a Velcro fur surface 5 is sewn on the outer wall of the bottom end of the airbag belt 310, and the Velcro fur surface 5 is located at an end away from the Velcro hook surface 4.

[0031] In this embodiment: when in use, the airbag belt 310 is wrapped around the patient's calf, and the Velcro hook surface 4 is adhered to the outer wall of the Velcro fleece surface 5, so that the airbag belt 310 is wrapped around and fixed to the patient's calf, and the internal gas of the piston cylinder 307 is transported to the inside of the airbag belt 310 through the air supply hose 309, so that the airbag belt 310 is inflated, thereby performing a squeezing exercise on the patient's calf.

[0032] Please refer to Figure 1 , Figure 2 A first threaded groove matching the outer wall of the connecting tube 305 is formed at the top of the lifting rod 304, a connecting groove matching the outer wall of the lifting rod 10 is formed inside the connecting tube 305, and a hand wheel 8 is fixedly connected to one end of the connecting tube 305.

[0033] In this embodiment: when in use, one end of the lifting rod 10 is inserted into the interior of a connecting tube 305, the other end of the lifting rod 10 is aligned with the other connecting tube 305, and then the handwheel 8 on the outer wall of the other connecting tube 305 is screwed, so that the handwheel 8 drives the other connecting tube 305 to rotate, while the other connecting tube 305 moves along the outer wall of the lifting rod 304, and the other connecting tube 305 is sleeved on the other end of the lifting rod 10, so that the two connecting tubes 305 are sleeved on the two ends of the lifting rod 10, thereby realizing the installation of the lifting rod 10.

[0034] Please refer to FIG. 5 , the lifting rod 304 has a limiting groove 9 formed inside, and the inner wall of the moving rod 303 has a limiting block 7 extending into the limiting groove 9 , and the outer wall of the limiting block 7 matches the inner wall of the limiting groove 9 .

[0035] In this embodiment: through the coordinated use of the limit block 7 and the limit groove 9, the movable rod 303 drives the lifting rod 304 to move horizontally.
