Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a blocking device for lower extremity deep vein thrombosis and a method of using the same. Background Art

[0002] Deep vein thrombosis of the lower extremities refers to blood clots formed by abnormal coagulation of blood in the deep veins of the lower extremities. It is common in the legs (such as the femoral vein, popliteal vein) or pelvic veins. The thrombus may partially or completely block blood flow, and in severe cases, it may cause fatal complications. Among the treatment methods for deep vein thrombosis of the lower extremities, the effect of thrombolytic therapy is very obvious. Clinically, the superficial venous plexus that compresses the ankle joint is generally used to drip urokinase through the deep vein for drug thrombolytic therapy. A yellow leather strip is used to tie the patient's lower limbs above the ankle, and pressure is applied to block the superficial veins to the maximum extent to open the deep veins, so that urokinase passes through the site where the thrombus occurs before passing through the body tissue, ensuring a higher local drug concentration for thrombus formation and exerting the maximum thrombolytic effect.

[0034] A method for using a blocking device for deep vein thrombosis of the lower limbs, comprising the following steps: a thigh blocking mechanism 1, a calf blocking mechanism 2 and an ankle blocking mechanism 3 have the same structure but different sizes, firstly, all airbag components 105 are in an uninflated state, and the thigh blocking mechanism 1, the calf blocking mechanism 2 or the ankle blocking mechanism 3 are put on the patient's thigh, calf or ankle, and when the thigh is blocked, the solenoid valve 104 on the thigh blocking mechanism 1 is opened, and the solenoid valves 104 on the calf blocking mechanism 2 and the ankle blocking mechanism 3 are closed, and the air pump 5 is started, and the gas passes through the first hose 6 and the second hose 7. The first connecting tube 103, the annular conduit 102 and the second connecting tube 107 are filled into the U-shaped airbag 1051, so that the U-shaped airbag 1051 expands to compress and block the thigh. The micro piezoelectric film sensor 1053 monitors the pressure of the U-shaped airbag 1051 on the thigh. The wireless transmission module 1054 transmits the pressure value to the terminal host 4 and is displayed on the display screen 8. When the pressure value reaches a suitable range, the solenoid valve 104 is closed. Similarly, the calf blocking mechanism 2 or the ankle blocking mechanism 3 can be operated to facilitate the adjustment of the compression force according to the actual needs of the vascular pressure requirements of the thigh, calf or ankle.

[0035] When in use, through the thigh blocking mechanism 1, the calf blocking mechanism 2 and the ankle blocking mechanism 3, the appropriate blocking mechanism can be selected for wearing according to the actual part that needs to be compressed. The remote control 10 and the terminal host 4 centrally control the air pump 5, the pressure relief valve 11 and the electromagnetic valve 104.

Start the air pump 5 and start to inflate the corresponding airbag assembly 105, so that the U-shaped airbag 1051 gradually expands, and several U-shaped The airbag 1051 applies uniform pressure to the compressed part, and the micro piezoelectric film sensor 1053 in the U-shaped airbag 1051 monitors the compression force in real time, so as to accurately reach the required pressure value. The wireless transmission module 1054 transmits the pressure value to the terminal host 4 and displays it on the display screen 8. The operator checks the pressure value on the display screen 8 and then closes the solenoid valve 104 and the air pump 5 after reaching the appropriate range. When the blocking mechanism needs to be removed, the solenoid valve 104 and the pressure relief valve 11 are opened to release the gas in the U-shaped airbag 1051, and then the blocking mechanism is removed.

When it is observed through the display screen 8 that there is no obvious change in the pressure value of a certain airbag assembly 105, it means that the airbag assembly 105 is damaged. At this time, the Velcro hook surface 1055 on the airbag assembly 105 is torn off from the Velcro fleece surface 106 on the annular duct 102, and then the air guide connector 1052 is pulled off from the second connecting tube 107 on the annular duct 102, so that the damaged airbag assembly 105 is disassembled, and then a new airbag assembly 105 is replaced. When the new airbag assembly 105 is installed, the air guide connector 1052 is first installed on the second connecting tube 107, and then the Velcro hook surface 1055 is attached to the Velcro fleece surface 106 to achieve partial replacement of the damaged structure.
