Leg venous thrombosis prevention and treatment device and control method thereof

Abstract

The invention discloses a leg venous thrombosis prevention and treatment device and a control method thereof, and belongs to the field of medical instruments. The device comprises a leg binding bag, pressurizing air bags, an air path connecting pipe, a heating device, an external wire and a prevention and treatment instrument. The control method comprises three control modes, namely a treatment mode, a rehabilitation mode and a leisure mode, and each mode corresponds to specific parameters. According to the device, the three-stage pressurizing air bags are adopted to carry out deep pressurization and relaxation on blood vessels of the legs of a human body, meanwhile, the heating device is used for enhancing blood circulation, and the formation of deep venous thrombosis can be effectively avoided and relieved by presetting reasonable pressurization numerical values, pressurization frequency and heating temperature; and the device is easy to wear and reliable in performance, particularly, the design scheme of three-air-bag step-by-step pressurization can ensure rapid backflow of venous blood, and the device can be widely applied to clinical medical instruments.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a device for preventing and controlling leg vein thrombosis and a control method thereof. Background technique [0002] Deep venous thrombosis (deep venous thrombosis, DVT) is a common clinical disease, especially lower extremity DVT. DVT can threaten the patient's life, and its sequelae seriously affect the patient's ability to work, and even become disabled. In the United States, DVT embolism is the third most common vascular disease, after coronary heart disease and hypertension. In my country, DVT embolism is also a common and frequently-occurring disease. [0003] Among them, lower extremity venous thrombosis is a common complication in patients during surgery and long-term bedridden patients, and it also occurs in healthy people who take transportation for a long time. Venous thrombosis of the lower extremities can affect the motor function of the limbs, lead to swelling o...

Problems solved by technology

[0004] The prevention and treatment of venous thromboembolism generally adopts drug therapy and physical therapy, and surgical therapy is adopted when necessary. Drug therapy and surgical therapy have large side effects, high risk, high treatment cost, and poor effect; there are many methods of physical therapy, among which Existing technologies include: electrode signal stimulation using sound current or direct current as a treatment source; high-frequency alternating homogeneous strong magnetic field or polymorphic strong gyromagnetic field and dynamic magnetic field interference therapy; ultrasonic generation of mechanical oscillations and thermal effects, biological effects Thrombus crushing method; fluctuating spectrum therapy; electrolytic resonance method; bioelectricity combined with music therapy; nano-laser therapy; health care preventive medical elastic stocking method; intermittent air pressure device method, etc. See Chinese invention patent "Meridian Painless Treatment Apparatus" (application number: 87101313, application date: 1987-03-12), Chinese invention patent "blood circulation aid" (application number: 90103535.1, application date: 1990-05-18) What is disclosed is a therapeutic instrument for promoting venous blood circulation. Its working principle is that the pulsating compressed air generated by the instrument is delivered to the air bag wrapped around the affected part, and the affected part is periodically squeezed to accelerate the venous blood flow and enhance the venous blood flow. Blood circulation, this instrument can prevent or treat venous diseases of the lower extremities for workers who have been engaged in standing or walking for a long time, and help to restore the vitality of athletes' limbs, but the specific air bag geometry and how to increase the inflation and deflation of the air bag are not specified in the invention Speed, to increase the compression and relaxation frequency of the affected part, etc.

In the prior art, especially in the relevant documents related to deep vein thrombosis treatment equipment, the specific structure of the pressurized air bag, as well as the specific driving and control methods are not described, nor is the leg combined with the pressurized air bag and infrared heating scheme The internal venous thrombosis prevention and treatment device has left a technical gap in this field in China
