Description

Automatic pneumatic lower limb massager
Technical Field
The invention relates to an automatic air pressure massager for lower limbs.
Background
When a human body is bedridden for a long time or sits for a long time, the condition that deep vein thrombus is formed on the lower limb easily occurs, the lower limb blood vessel is blocked and lesion is caused, pulmonary embolism and other serious clinical conditions are easily caused.
Clinically, for patients lying in bed for a long time and patients lying in bed after surgical operation, low molecular heparin subcutaneous injection, oral anticoagulant drugs, methods of raising limbs of the lower limbs, strengthening muscle massage of the limbs of the lower limbs and the like can be adopted, so that the problems of unsmooth blood flow, muscular atrophy and the like of the veins of the lower limbs, particularly deep veins can be solved, and the occurrence of clinical serious complications such as pulmonary embolism and the like can be reduced and prevented.
However, the above methods are time-consuming, laborious and uncertain in therapeutic effect; the anticoagulation therapy cannot be applied due to intracranial hemorrhage, high postoperative bleeding risk, gastrointestinal hemorrhagic lesion and the like of a patient, and meanwhile, the anticoagulation therapy also brings important organ bleeding risk to the patient.
And for the old, the patients with diabetes, Parkinson and the like, the venous thrombosis of the lower limbs is very easily formed under the conditions of long-time inactivity, long-time sitting (such as long-time airplane travel, long-time meeting) and the like, and the method is also not suitable for long-term application of medical anticoagulation treatment.
The blood circulation of the lower limbs of the patient can be effectively enhanced by manually massaging the lower limbs of the patient from bottom to top or from top to bottom in sequence. Reduce the venous thrombosis of the lower limbs and reduce and avoid the occurrence of serious complications such as pulmonary embolism and the like. Meanwhile, the repeated contraction and massage effects of the lower limb circulation auxiliary device can also prevent the occurrence of the muscle atrophy of the individual. However, the manual massage is high in cost and labor intensity, and is difficult to benefit all patients.
2012.10.03 the authorized bulletin number is: CN 202459232U, a chinese utility model discloses a pneumatic leg-wrapping massage device for lower limbs. The split air bags are mutually communicated, have no functions of local inflation and local pressing, and certainly can not extrude and massage the lower limbs of patients from top to bottom or from bottom to top.
