Description

Technical Field

[0001] The utility model relates to the technical field of clinical nursing lifting devices, in particular to a clinical nursing auxiliary lifting device. Background Art

[0002] Clinical nursing lifters are an auxiliary tool widely used in medical care. For patients with limited mobility, especially those who are bedridden for a long time or are physically weak, they can provide stable support to assist them in moving from lying to sitting positions, reducing the workload of nursing staff and the risk of injury to patients during the process of getting up.

[0003] The above device does not have a structure that assists the patient to stand up from the lying position, sitting position and standing position one by one when in use, so that the existing hospital clinical nursing beds can only switch the patient from the lying position to the sitting position when in use. It is unable to continue to assist the patient to stand up during the subsequent getting out of bed, which is inconvenient to use. Based on the shortcomings of the existing technology, the utility model designs a clinical nursing auxiliary lifting device. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a clinical nursing auxiliary raising device, which has the advantage of assisting the patient in rising from a lying position, a sitting position and a standing position one by one.

[0006] The raising mechanism includes a main raising plate, a rotary joint, a reducer, a driving machine, a screw, a threaded slider, a support push arm and a hinged joint. The main raising plate is rotatably connected to the upper surface of the supporting foot, the rotary joint is arranged between the main raising plate and the bedside mattress, the reducer is fixedly connected to the upper surface of the bed frame, the driving machine is fixedly installed on one side of the reducer, the screw is rotatably connected to the other side of the reducer, and the screw is connected to the output end of the reducer, the threaded slider is threadably connected to the screw, the support push arm is rotatably hinged to the top end of the threaded slider, and the hinged joint is rotatably hinged to the top end of the support push arm.

[0007] As a preferred technical solution of the present invention, the lower surface of the medical bed body is fixedly connected to a support foot, side rails are provided on both sides of the medical bed body, a control button is fixedly installed on one side of the medical bed body, and head and tail baffles are fixedly connected to the front and rear ends of the medical bed body.

[0008] As an optimal technical solution of the present invention, the auxiliary lifting plate is rotatably connected to the inside of the top groove, and the top groove is opened on the upper surface of the main lifting plate. The upper surface of the top groove is provided with a first receiving groove, and the lower surface of the auxiliary lifting plate is provided with a second receiving groove. The inside of the first receiving groove is fixedly connected to a rotating seat, and the rotating seat is rotatably connected to a telescopic electric cylinder.

[0009] As a preferred technical solution of the present invention, the control button is electrically connected to the driving machine and the telescopic electric cylinder respectively.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The clinical nursing auxiliary lifting device controls the telescopic electric cylinder to start and extend by a control button to push the auxiliary lifting board to rotate. The auxiliary lifting board rotates upward and expands to push the patient's back to gradually stand upright and switch to a sitting position. At this time, the patient can hold the side railing close to the bedside mattress to move his legs from the bed to the outside. Then the control button is used to control the driving machine to start, and the speed reducer drives the screw to rotate. The rotating screw drives the threaded slider to move to one side and pushes the supporting push arm to gradually stand up under the limit of the hinged joint. At the same time, the erected supporting push arm also pushes the main lifting board to slowly rotate upright under the limit of the rotating joint to gradually push the patient to the bedside and support the patient's back to prevent the patient from lying down again due to lack of support after being in a lying position. The device is convenient for assisting patients to move from a lying position to a standing position. BRIEF DESCRIPTION OF THE DRAWINGS

The upward rotating and expanded auxiliary raising board 2 pushes the patient's back to gradually stand upright and switch to a sitting position. At this time, the patient can hold the side railing 104 on the side of the bedside mat 103 to move his legs from the bed to the outside. Then the control button 105 is used to control the driving machine 304 to start and drive the screw 305 to rotate through the reducer 303. The rotating screw 305 drives the threaded slider 306 to move to one side and push the support push arm 307 to gradually stand up under the limit of the hinge joint 308. At the same time, the erected support push arm 307 also pushes the main raising board 301 to slowly rotate upright under the limit of the rotating joint 302 to gradually push the patient to the bedside and support his back to prevent him from lying down again due to lack of support after being in a lying position. This device is convenient for assisting patients to move from a lying position to a standing position.
