Description

Technical Field

[0001] The utility model relates to the technical field of emergency equipment, in particular to a lower limb fixing and restraining device. Background Art

[0002] The emergency medicine department or emergency medicine center is the department in the hospital with the highest concentration of critically ill patients, the most diseases, and the heaviest rescue and management tasks. It is the only way for all emergency patients to be admitted to the hospital for treatment. In emergency clinical practice, due to the diversity of patients, some special patients need to have their lower limbs fixed and restrained. When fixing and restraining the patient's lower limbs, a lower limb fixation and restraint device is required.

[0003] The restraint device in the prior art cannot effectively adjust the distance between the fixing sleeves when restraining the patient's lower limbs. Since the fixing sleeves in the restraint device in the prior art are integrated with the device, the restraint device has high limitations and cannot restrain the lower limbs of patients with different leg lengths. When restraining the lower limbs of patients with different leg lengths, the restraint device may not be able to effectively fix and restrain the patient's lower limbs, thereby affecting the fixation and restraint effect of the restraint device on the patient's lower limbs, which in turn affects the patient's lower limb treatment effect. At the same time, it may also cause the patient to feel uncomfortable after the lower limbs are restrained and fixed, which also affects the patient's treatment effect.

[0004] Compared with the Chinese patent with announcement number CN216318587U, the utility model relates to the technical field of emergency equipment, and discloses an emergency clinical lower limb fixation and restraint device, including a mounting plate, a connecting plate is arranged on the inner side of the mounting plate, and a locking bolt is arranged on the side of the upper end of the mounting plate. The utility model uses the airbag to be inflated, and after the airbag is expanded, the gasket fits the patient's lower limb, and the restraint belt is installed in the connecting buckle, so as to achieve the fixation and restraint of the lower limb, and reduce the pressure on the lower limb during restraint. At the same time, a cavity is formed between the multiple airbags, which is convenient for ventilation and air permeability, increases the air permeability effect of the restraint position, greatly improves the comfort, and utilizes the adhesion of Velcro to tear off the first gasket and the second gasket respectively, and then replace the new gasket, which is convenient for the disassembly and replacement of the first gasket and the second gasket, improves the medical hygiene and convenience of the fixed restraint device, facilitates the secondary use of the lower limb fixed restraint device, and reduces the workload of medical staff.

[0005] The above scheme can very conveniently fix and restrain the patient's lower limbs, and can also easily disassemble and replace the gasket, thereby improving the hygiene and convenience of the restraint device. However, the fixing sleeve and the device in the above scheme are still integrated, and the device cannot be adjusted according to the leg length of different patients, which reduces the practicality of the device. Different patients may still encounter problems such as poor fixation effect after using the restraint device to fix their lower limbs, and the problems raised in the above background technology are not solved.
