Abstract
Description
Technical Field
[0001] The invention relates to the field of surgical nursing, and in particular to a limb lifting device for surgical nursing. Background Art
[0002] Limb lifting devices in surgical nursing mainly have the effects of promoting blood circulation, preventing edema and accelerating recovery. When patients' limbs are injured or need to be immobilized after surgery, blood circulation is easily blocked, resulting in edema at the distal end of the limb. Limb lifting devices can lift the limbs to an appropriate height, and can use gravity to promote blood return and reduce the accumulation of tissue fluid at the end of the limb, thereby effectively preventing and alleviating edema symptoms. Good blood circulation helps to provide sufficient nutrients and oxygen to injured tissues or surgical sites, promote cell regeneration and repair, and accelerate wound healing and the patient's recovery process;
[0003] At the same time, injured or post-operative limbs are often accompanied by pain, and swelling will further aggravate the pain. By lifting the limbs, the pressure of swelling on the surrounding nerves and tissues can be reduced, thereby relieving pain. It can also reduce the tension of muscles, fascia and other tissues around the injured part or surgical incision, and reduce the pain and discomfort caused by excessive tension. In conjunction with other treatment measures, after the limbs are lifted, it is easier for medical staff to observe the color, temperature, degree of swelling and other conditions of the limbs, and to detect problems and deal with them in a timely manner. At the same time, it is also convenient for wound care, dressing changes and other operations;
[0004] The top lifting position of the limb lifting device used in current surgical nursing practice is usually designed to be fixed. This fixed design is not flexible and convenient for patients of different heights or who need assisted lifting of specific body parts. In addition, for patients who rely on limb lifting for rehabilitation training, the existing devices are limited due to the lack of adjustability and are difficult to meet their diverse rehabilitation needs. Furthermore, in the process of releasing the limb lift, due to the effect of the patient's own gravity, the operator must use extra force to control the lifting device to ensure that the patient's limbs can descend slowly and steadily, which undoubtedly increases the difficulty of operation and the workload of medical staff.
[0005] Therefore, it is necessary to provide a new limb lifting device for surgical care to solve the above technical problems. Summary of the invention

[0017] Compared with the related art, the limb lifting device for surgical care provided by the present invention has the following advantages:
[0018] Beneficial effects:
[0019] 1. By combining the use of two lifting components, a limiting component and a fixed frame, multi-directional and multi-posture limb lifting can be achieved according to the height and weight of different patients. This design allows the selection of fixed-position or fixed-weight assisted lifting training methods according to the specific needs of each patient, thereby providing personalized care plans for patients in different situations. This not only improves the flexibility of assisted limb lifting, but also greatly reduces the physical burden of medical staff when performing lifting operations.
[0020] 2. The coordinated work of the pulley block and the winch assembly in the lifting assembly can effectively reduce the force required to lift the patient's limbs. In addition, the winch assembly cooperates with the speed limiting component to ensure that the limbs slowly descend to the auxiliary bed board when the patient's limbs lose support, avoiding rapid falling due to sudden loss of control, thereby protecting the patient from secondary injury. At the same time, when the winch assembly is performing the lifting work, the speed limiting component is in the open state and will not limit the speed of the telescopic rope. When the patient does not need to lift his limbs, the pull rod is toggled to allow the speed limiting component to apply force to the telescopic rope, so that the patient's limbs slowly descend to the auxiliary bed board.
[0021] 3. The connectors are designed in two types and can be used in conjunction with the patient's limbs and turning boards to achieve a multifunctional combination of patient turning and limb lifting, meeting a variety of care needs and reducing dependence on additional equipment. Secondly, different connectors can be adjusted and configured according to the patient's specific circumstances, making the care process more personalized and efficient. During turning and lifting, stable connectors can ensure the patient's safety and reduce potential risks caused by improper movement, such as skin friction or muscle strain. In addition, with the help of these connectors, medical staff will save more effort when performing turning and lifting operations, reducing the intensity of physical labor and improving work efficiency, thereby improving the patient's overall comfort and satisfaction.
[0022] 4. The design combining the fixed frame and the limiting components can also support the hanging input of medical drugs and the convenient installation of other medical devices, further improving the functionality and practicality of the equipment and making the entire nursing process more efficient and smooth.
