Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a lower limb air pressure treatment bed for patients undergoing pelvic organ prolapse surgery. Background Art
[0002] Patients who need surgery for pelvic organ prolapse are generally elderly patients. Pelvic floor surgery is generally more complicated and takes a relatively long time. There is a high risk of lower limb thrombosis during and after the operation. If secondary pulmonary embolism occurs, the patient's life will be in danger. At present, clinical measures to prevent thrombosis after surgery for patients with pelvic organ prolapse are relatively complete, including postoperative lower limb air pressure therapy, elastic stockings and leggings, lower limb warmth, promotion of early bed activities, subcutaneous injection of low molecular weight heparin, etc. The prevention mechanism is generally to prevent lower limb thrombosis by promoting the blood flow velocity of the lower limb veins, reducing the hypercoagulable state of the blood, and giving full play to the function of the lower limb venous pump.
[0003] Traditional operating tables require both lower limbs to be supported and fixed separately by two leg supports. The load-bearing position of the supports acts on the back of the thighs above and below the knees. Under the pressure of the patient's own gravity, the venous return of both lower limbs is hindered to a certain extent, increasing the risk of lower limb thrombosis during surgery. In addition, for many elderly patients, the blood flow in the lower limbs is slowed down. The surgery for pelvic organ prolapse often lasts 2-3 hours or even longer. The patient continues to maintain an unnatural posture with both lower limbs drooping during the operation, which further increases the risk of lower limb thrombosis. Utility Model Content
