Embodiment Construction

[0008] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0009] Depend on Figure 1-2 Given, the present invention comprises fan-shaped airbag and main engine, and fan-shaped airbag 1 extends radially and is divided into several adjacent and respectively closed subsection airbags, and pressure check valve 4 is arranged between each subsection airbag, and the bottom section airbag One end is provided with an air inlet, and the air inlet is connected to the compressed air pipeline 5. The compressed air enters from the lowermost airbag, and inflates and pressurizes from bottom to top in order to assist the venous blood of the lower extremities to run upwards to achieve the effect of normal backflow. A pressure sensor 8 is arranged in the air bag of the uppermost segment, and the signal line 8a of the sensor signal passes through the signal line 8a of the pressure sensor 8 and is ...

Abstract

The invention relates to a section-by-section pressurization lower limb vein auxiliary backflow air sac which is capable of solving the problem of unsmooth lower limb vein backflow or thrombosis effectively. According to the technical scheme, the sectorial air sac is divided into a plurality of section air sac bodies which are adjacent and sealed respectively along the radial direction. A pressure check valve is arranged between every two section air sac bodies. An air inlet is formed in one end of the air sac body in the bottom section and is connected with a compression air pipeline. A pressure sensor is arranged in the air sac body in the top section, and a signal line of the pressure sensor stretches out one end of the air sac body. An air leakage hole is formed in one end of the air sac body in each section and is connected with a mini solenoid valve, and all mini solenoid valves are connected in parallel into an air leakage execution line. By means of the air sac, the defect that lower limbs are squeezed and massaged by applying overall equal pressure of some passive measures in the prior art is overcome, and the air sac is innovative as for unsmooth lower limb vein backflow or thrombosis prevention and auxiliary treating devices.

Description

technical field [0001] The invention relates to a medical device, in particular to a stepwise pressurized lower extremity venous auxiliary reflux air bag, which is used for preventing and assisting in the treatment of poor venous return or thrombosis in the lower extremities. Background technique [0002] The deep veins of the lower extremities are the main channels for the return of blood from the lower extremities. Deep vein thrombosis of the lower extremities is when a blood clot forms in this passage. In addition to blocking venous return and causing lower extremity edema, and destroying the structure and function of lower extremity veins and valves, the hazards can also cause pulmonary infarction and sudden death that is difficult to rescue if the thrombus falls off. Lower extremity deep vein thrombosis has become a common disease at home and abroad that endangers the health of the people. Slowing or even stopping of blood flow velocity in veins is one of the main ...
