Embodiment 1

[0062] Please combine image 3 , first make the PVC myelin fiber 22 in the PVC gel-driven tightening ring, use PVC particles with a degree of polymerization of 3700, and plasticizer dibutyl adipate (DBA) in a mass ratio (1:3)- (1:5), mixed in the ratio of 1:4 in this preferred example, after mixing, add the organic solvent tetrahydrofuran for dilution, the mass ratio of the mixture mass to tetrahydrofuran is (2:3)-(2:7), this preferred In the example, 1:3 is taken as an example, and it is configured as a polymer solution. Polymer solution and silver-plated yarn 222 with a diameter of 0.4 mm are coaxially extruded to produce PVC myelin fibers 22 with a total diameter of 1 mm.

[0063] Secondly, a copper-coated plastic fiber with a diameter of 2 mm is used as the anode. Through the alternate weaving of PVC myelin fibers 22 and anode conductive fibers 21, the rigid conductive fibers 21 are along the vertical direction of the tightening ring, while the PVC myelin fibers 22 are i...

Embodiment 2

[0067] refer to figure 2 A plurality of PVC gel-driven tightening rings 11-15 are sequentially arranged on different parts of the leg of the stocking 1 to form a main body of PVC gel-driven electrically controlled gradient pressure elastic stockings. The power supply module 31 , the control circuit 32 and the control panel 33 are integrated into the wearing module 3 .

[0068] Make it generate a sequence voltage of corresponding magnitude, and load it to the tightening rings 11-15 driven by different multi-layer PVC gels through the electrical connecting wire 2, so as to generate corresponding tightening force. Provide patients with intermittent tightening massage to promote blood circulation in the lower limbs.

Abstract

The present invention is a polyvinyl chloride gel-driven intermittent self-controlled electronically controlled gradient pressure elastic stocking and a preparation method thereof. A gel-driven tightening ring, an electrical control module, and an electrical connection wire connecting the tightening ring and the electrical control module; the preparation method sequentially includes configuring a polymer solution, obtaining PVC myelin fibers, forming an annular band-shaped tightening ring, and forming a connection Compression stockings. Through the electric control module, voltage is applied to multiple PVC gel tightening rings sequentially distributed on the stockings, and the circumferentially arranged tightening rings generate tightening forces distributed according to the set time sequence, which can generate different sizes in a certain time sequence. The electronically controlled gradient pressure that can be circulated simulates the action of the muscle pump, pressurizes and massages the corresponding parts of the lower limbs, promotes blood circulation in the lower limbs, and effectively prevents venous thrombosis of the lower limbs; it is light, comfortable to wear, easy to operate, and has high promotion and application value.

Description

technical field [0001] The invention relates to a wearable auxiliary treatment device, in particular to a polyvinyl chloride gel-driven intermittent self-controlled electronically controlled gradient pressure elastic stocking and a preparation method thereof. Background technique [0002] Acute venous thrombosis is a clinically more harmful disease at present. It usually occurs insidiously, but once the thrombus falls off, it will cause acute pulmonary embolism and other diseases that seriously threaten the lives of patients. At present, the main clinical treatment for acute venous thrombosis is prevention. For high-risk patients undergoing major surgery, suffering from tumors, pregnancy, and long-term bed rest, various physical preventions including elastic stockings are emphasized, and anticoagulant drugs and other drug prevention are even given when necessary. [0003] Compression stockings are currently one of the most commonly used physical methods to prevent lower ext...
