Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, in particular to a hip lifting device. Background Art

[0002] Medical devices refer to various equipment, supplies, materials or other items used to prevent, diagnose, treat diseases or provide physiological function support inside or outside the human body; hip lifts fall into the category of medical devices. Hip lifts are used to assist patients with hip fractures to lift their buttocks off the bed, thereby facilitating urination and defecation for patients with hip fractures, as well as medical staff's care for patients with hip fractures.

[0003] After searching, a patent document with patent publication number CN214549949U discloses a hip lifting instrument, including a base, a column, a beam, a bearing, a crank, a gear, a mounting plate, a mounting hole, a connecting rod, a pedal, a limit block, a tooth tip, a spring, a winding groove, a pull rope, a hook, a pocket pad and a pocket strap. There are two bases, and the two bases are arranged in parallel. A vertically arranged column is fixed at the center position of the upper part of each base, and a horizontally arranged beam is provided between the upper ends of the two columns. Two bearings are sleeved on the outer side of the beam, and the inner ring of the bearing is fixedly connected to the outer side of the beam. The outer rings of the two bearings are respectively fixedly connected to the upper ends of the two columns. A crank is fixed at one end of the beam, and a gear is fixedly sleeved on the outer side of a section where the crank is connected to the beam. Compared with the existing technology, it is convenient to lift the patient's buttocks. The instrument has strong adaptability, simple structure, and easy operation, which brings great convenience to the care of patients with hip fractures.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. The above-mentioned hip lifter has two bases, which are arranged in parallel. A vertical column is fixedly provided at the center position of the upper part of each base. A horizontal beam is provided between the upper ends of the two columns. Two bearings are sleeved on the outer side of the beam. The inner ring of the bearing is fixedly connected to the outer side of the beam. The outer rings of the two bearings are fixedly connected to the upper ends of the two columns respectively. A crank is fixedly provided at one end of the beam. A gear is fixedly provided on the outer side of a section where the crank is connected to the beam. A horizontal mounting plate is fixedly provided on the side of the column. The mounting plate and the crank are located on the same side of the beam. A mounting hole is provided on the upper part of the mounting plate which vertically passes through the mounting plate. A vertical connecting rod is inserted into the mounting hole. The connecting rod slides vertically with the mounting hole. A horizontal pedal is fixedly provided at the lower end of the connecting rod. A limit block is fixedly provided at the upper end of the connecting rod. The upper part of the limit block is fixed with a linearly distributed tooth tip, which is meshed with the gear. A spring is sleeved on the outer side of the part of the connecting rod above the mounting hole. The upper end of the spring is fixedly connected to the bottom of the limit block, and the lower end is fixedly connected to the upper part of the mounting plate. When the patient's hip needs to be lifted, the pocket pad is positioned under the patient's back in advance, and the medical staff steps on the pedal with their feet to make the connecting rod slide downward in the mounting hole, so that the tooth tip on the upper part of the limit block is separated from the gear. Then the family member turns the crank to make the crossbeam rotate, and the winding groove starts to wind the pull rope to make the hook rise. The hook pulls up the pocket pad through the pocket strap, and the patient's body will rise together with the pocket pad, and the patient's hip will be lifted off the bed surface. However, there are many steps to achieve the patient's hip lifting operation, and it requires the cooperation of multiple people to operate, thereby increasing the workload of medical staff and making it inconvenient for one person to operate.

[0006] 2. The above-mentioned hip-lifting device has an annular winding groove in the middle of the outer side of the beam, one end of the pull rope is fixedly connected to the bottom of the winding groove, and the other end of the pull rope is fixedly connected to a hook, the rope body of the pull rope is wound inside the winding groove, and a pocket pad is provided directly below the hook, and the four corners of the pocket pad are fixedly connected to pocket straps, which are hung on the hook, so that the patient's buttocks are placed on the pocket pad, and the stretch is performed to reel in the pocket pad to lift the patient's buttocks. However, since the patient's buttocks are on the pocket pad, it brings inconvenience to the operation of replacing the pocket pad.

[0007] To this end, we provide a hip lift to solve the above problems. Utility Model Content

[0008] The purpose of the present invention is to provide a hip lifter. By setting a lifting component, medical staff only need to operate the hydraulic cylinder to lift and lower the patient's buttocks, reducing the amount of operation for medical staff.
