Detailed Description

The basic structure of the embodiment is an intelligent full-automatic turnover nursing bed or an intelligent voice control/manual control full-automatic turnover nursing bed in the prior art, and an electric device for assisting a patient to stand up from a seat is additionally arranged on the basis of the prior art.

The upper steel plates 5-1 and 5-2 of the hip-thigh plate are made of steel plates with the thickness of 2-3 mm; the electric push rod 8 adopts 600N high thrust 12V/24V50W stroke 30 cm; the power assisting arm slide rod 19 is made of steel, the main body of the power assisting arm slide rod is T-shaped, other parts are sold in the market, related parts are manufactured according to the specification requirement and referring to the attached drawings, and the power assisting arm slide rod can be used after various parts are assembled and debugged. When the multifunctional nursing bed is used, a patient or a nursing person operates a touch screen 26-1, a controller 26-2 and a control handle 26-3 of the nursing bed to form a seat key, if an intelligent sound control device is arranged, a sound control command of sitting up is sent, a back lifting electric push rod (1-9), a leg movement electric push rod (1-10) runs, the back rises, legs droop, and a seat armrest is automatically formed, so that the patient is in a sitting state. When a patient wants to get off the bed, the power supply of the power-assisted electric push rod 8 is automatically connected by pressing the power-assisted lifting key K1 or sending a voice control instruction of ' help stand ', the speed reduction motor M of the electric push rod positively operates the telescopic rod 13 of the electric push rod to gradually extend to generate upward thrust, the thrust passes through the short circular connecting pipe 20 matched and tightly matched with the top 13 ' of the telescopic rod, the T-shaped power-assisted arm sliding rod 19 and the sliding bearing/pulley 22 at the tail end of the T-shaped power-assisted arm sliding rod are synchronously lifted, the sliding bearing/pulley 22 slides in the sliding groove 23, the strong acting force pushes the hip-thigh upper plate 22 to move around the shaft by taking the hinge or the rotating shaft 7-1-7-4 arranged at the foot side as the shaft center, the angle is gradually increased to 75 degrees from 0 degrees, the upward thrust of the telescopic rod 13 of the power-assisted electric push rod 8 is converted into upward and forward thrust, and the hip-thigh upper plate 5-1, 5-2, lifting upwards and forwards, and lifting the patient sitting on the chair upwards and forwards with strong lifting force; because the telescopic rod 13 of the electric push rod penetrates into the matched circular hole 14 of the plastic plate, a plastic component 16 for preventing the telescopic rod 13 from shaking is manufactured and is fixed on the upper transverse frame 18 of the nursing bed by bolts; therefore, the electric push rod can be prevented from shaking and shifting in the extension process. Meanwhile, hinges/rotating shafts 6-1 and 6-2 which are arranged at the front center and the rear center of the excrement opening 2-2 connected by the steel plate and are convenient for turning over transmit upward and forward lifting force to the other side, but because the side is lack of the lifting support of the power-assisted arm sliding rod 19, the transmitted lifting force is slightly weak, and the gravity of a patient enables the upper steel plate 5-2 of the hip-thigh of the side to sink; however, since the lower end of the gas spring support rod 24 is hinged to the upper portion of the angle steel support rod coupling part 25, the lower end of the component is fixed on the bottom frame 1 of the hanging bracket 11 of the automatic transfer-opening/closing device 10 of the bed pan, the air pressure support rod 24 is elastically retracted under the gravity action of the patient when the patient is in the supine position or sitting position, the elastic potential energy is stored, when the power supply of the power-assisted electric push rod M is switched on, the motor operates in the positive direction to extend the telescopic rod to generate upward strong thrust, the pushing force is converted into upward and forward pushing force through the aid arm slide bar-chute device and is transmitted to the side, the elastic potential energy of the compressed air spring support bar 24 at the side is released to generate stronger elastic force, and the defect that the pushing force is slightly weak at the side due to the lack of the aid arm slide bar 19 and chute 23 devices at the side, so that the side sinks under the action of the body weight of a patient is overcome; the upper steel plates 5-1 and 5-2 of the buttocks and thighs at two sides assist the patient to stand up from the sitting position, so that the patient with light disability degree can be improved in self-care ability, the labor intensity of nursing staff can be obviously relieved for the patient with serious disability, and the electric push rod 8 has strong thrust, the thrust is up to 6000N and is equivalent to an electric jack, so that the function of assisting the patient to stand up from the sitting position can be easily realized even for the patient with serious obesity and the weight of 150 Kg. Because the force-assisting arm slide rod 19 is made of steel and the main body is in a T shape, the force-assisting arm slide rod 19 cannot be bent and deformed even if the weight of a patient is heavy. Hinges or rotating shafts 6-1 and 6-2 which are convenient to rotate when the patient turns over are arranged at the centers of the front and rear ends of the upper steel plates 5-1 and 5-2 of the hip-thigh plate; therefore, when a patient turns over to the left side or the right side, the right side or the left side bed board can still smoothly complete the left side or the right side electric turning-over function by taking the hinges/rotating shafts 6-1 and 6-2 as axes to move around the shafts under the pushing of the turning-over electric push rod 1-8.1-8'. When a patient wants to sit down on a bed, the patient with light disability degree can lean the buttocks against the hip-thigh upper steel plates 5-1 and 5-2 with the angle of 75 degrees and hold the buttocks on the armrests 11-1 and 11-2 of the chair, the patient with serious disability degree needs to be assisted by nursing staff, a reset key K2 is pressed or a voice sound control instruction for helping to sit down is sent, the speed reducing motor of the electric push rod moves reversely, the telescopic rod 13 of the electric push rod 8 is gradually shortened until the patient recovers, and the hip-thigh upper plates 5-1 and 5-2 and the pneumatic spring support rod 24 synchronously and gradually descend to recover the original position under the action of the gravity of the patient, so that the patient is driven to slowly recover the sitting position from the standing position. Because the touch screen 26-1, the controller 26-2, the control handle 26-3 and the micro control box 26-4 are all provided with the stop key (K0), the stop key K0 can be pressed at any time according to the will of a patient during the operation of the electric push rod 8, so that the operation is stopped. And the intelligent voice control device is arranged to send a voice control command of 'stop' to stop the operation.
