What Does a DVT Pump Do in Thrombosis Prevention

Wednesday, 08/6/2025

This article explains the role of DVT pumps (compression therapy devices) in thrombosis prevention. It first outlines key facts about Deep Vein Thrombosis (DVT), including its causes, risks of pulmonary embolism (PE), and high mortality. Focusing on how DVT pumps work, it highlights their safety (no bleeding risk), effectiveness (accelerating blood flow via sequential compression), and convenience. It details features of the LONGEST LGT-2200DVT, such as multi-mode control and overpressure protection, along with therapeutic mechanisms, indications, contraindications, and precautions, emphasizing their role in preventing DVT and improving patient care.

Basic Understanding of Deep Vein Thrombosis (DVT)

Deep Vein Thrombosis (DVT) is a venous reflux disorder caused by abnormal blood clotting in deep veins, most commonly occurring in the lower limbs. If the thrombus detaches, it can lead to pulmonary embolism (PE); together, they are referred to as venous thromboembolism (VTE). DVT often results in PE and post-thrombotic syndrome (PTS), and in severe cases, significantly impairs quality of life or even causes death.

The main causes of DVT are hypercoagulability, blood stasis, and vascular wall damage, with clinical features of high incidence, high concealment, and high mortality. For example, the incidence of lower extremity DVT after surgery is relatively common; domestic literature reports that the incidence of DVT after surgery is 26%. About 80% of DVT patients have no symptoms, and only a small number are detected before pulmonary embolism. Once a DVT embolus detaches and causes pulmonary embolism, the mortality rate is as high as 70%. Thus, preventing DVT in rehabilitation nursing is urgent.

How DVT Pumps (Compression Therapy Device) Prevent Thrombosis

Safety

Anticoagulants easily increase the risk of wound exudation and edema aggravation in patients and are less safe for patients with bleeding tendencies or coagulation disorders. In contrast, compression therapy devices (DVT pumps) use physical compression. Sequential positive pressure therapy does not increase the risk of bleeding and has no potential side effects. Studies have shown that after sequential positive pressure therapy, lower extremity venous blood output increases by 23%, and blood flow velocity increases by 77±35%.

Effectiveness

DVT pumps prevent thrombosis by sequentially compressing the lower limbs, causing muscle deformation, vasoconstriction, and dilation, and accelerating blood circulation, thereby effectively avoiding blood coagulation.

Convenience

DVT pumps adopt physical compression, with an intuitive display and simple operation.

DVT PUMP

Features and Advantages of Longest Compression Therapy Device (LGT-2200DVT)

DVT PUMP

Design Details: Portable handle, bedside hook, and segmented DVT airbags.
Core Functions:
- Multi-mode control: 4 modes to meet various clinical treatment needs.
- Real-time pressure monitoring: Ensures airbag pressure stays within the set safe range.
- Overpressure protection system: Automatic pressure relief to avoid patient injury from excessive pressure.

Therapeutic Mechanism of DVT Pumps

After the control host inflates the sleeve, each chamber forms a certain pressure. Each chamber sequentially completes inflation, holding, and deflation. Through the mechanical effect of periodic compression and decompression, DVT pumps promote blood and tissue fluid circulation in the limbs, relieving clinical symptoms such as limb edema, pain, soreness, and heaviness.

Indications for DVT Pumps (Focus on Thrombosis Prevention)

Preventing the formation and recurrence of deep vein thrombosis
Limb edema due to insufficient reflux (e.g., prolonged sitting, pregnancy)
Increased vascular permeability caused by trauma, surgery, or infection
Venous stasis ulcers
Stump swelling after amputation
Limb trauma and orthopedic diseases
Diabetic peripheral neuropathy
Post-surgical lymphedema (e.g., after radical mastectomy)
Lower extremity varicose veins
Complex regional pain syndrome (e.g., neurogenic reflex edema, post-stroke hemiplegic limb edema)

Contraindications for DVT Pumps

Congestive heart failure or pulmonary edema
Acute deep vein thrombosis or thrombophlebitis
Complete obstruction of lymphatic or venous reflux
Peripheral arterial disease or ulcers
Acute local skin infection
Severe hypoproteinemia
Acute trauma or fractures
Post-arterial revascularization surgery
Uncontrolled hypertension

Precautions for Use

Tumors
Stroke or severe cerebral insufficiency
Superficial peripheral nerves

Effective Gradient Compression DVT Pump LGT-2200DVT

The LGT-2200DVT is a compression therapy device comprised of an intermittent pneumatic controller (main unit), sleeves, and a connection hose. Its working principle is that air inflates and deflates the sleeves sequentially to generate circulating pressure on the human body. By squeezing the proximal and distal limbs, it can directly or indirectly promote blood circulation and the lymphatic system, improve body micro-circulation, prevent thrombi, and reduce limb swelling. It addresses diseases related to blood and lymph circulation. It is widely used in hospital settings to improve workflow efficiency and enhance patient care.
