Company Introduction

Deep vein thrombosis (DVT), is a blood clot that forms in a vein deep in the body (thrombus). Blood clots occur when blood thickens and clumps together. Some clots can disappear naturally, or with the aid of certain drugs. Most deep vein blood clots occur in the lower leg or thigh. They also can occur in other parts of the body. A blood clot in a deep vein can break off and travel through the bloodstream. The loose clot is called an embolus. When the clot travels to the lungs and blocks blood flow, the condition is called pulmonary embolism (PE). Knee and hip surgery patients have the highest risk of developing DVT and PE in the surgical setting.

What Is Deep Vein Thrombosis?

PE is a very serious condition. It can damage the lungs and other organs in the body and cause death. Blood clots in the thigh are more likely to break off and cause PE than blood clots in the lower leg or other parts of the body. DVT occurs most frequently among people who are immobilised. For example, the condition has been long recognised as a risk for people confined to bed. Immobility for even short periods can cause DVT. For this reason, preventive measures are frequently taken when people, particularly the elderly, undergo surgical operations, where they are immobilised by a general anaesthetic. The increased proportion of PE are in association with identified risk factors for DVT, which include increasing age, obesity, smoking, pregnancy, the use of oral contraceptives or hormone replacement therapy, cancer, lower limb injury or surgery, family history of DVT, and previous thrombosis or embolism.

Treatment / prophylaxis Anticoagulants Antiplatelet Drugs IPC system

Pulmonary Embolism

About half of all DVT cases are asymptomatic, with no obvious self-consciousness or clinical symptoms. In symptomatic cases, the affected (diseased) area can become swollen, thickening periodically resulting in pain or compression. Skin color / composure may be compromised. Clinical symptoms of PE

Breast pain Hemoptysis Dyspnea

Clinical sysmptoms of DVT

Air is injected periodically and orderly from the malleolus and the calf to the thigh.

DVT is prevented by two principles.

• The blood flow of the crural vein is accelerated in order that venous congestion can be rapidly removed. The pressure is periodically increased or reduced, and thus pulsating blood flow runs through the deep vein systems of telomeric sites and crural blood is favorably circulated. Coagulant factors are prevented from swarming and sticking to the tunica intima, and as a result thrombosis is prevented.

• The fibrinolysin system is more activated, and the activtion of fibrous proteinlysis caused by internal causes is stimulated after use whether they are the normal or patients with phlebothrombosis. It appears that the mechanism works because the plasminogen activator inhibitor-1 is decreased and the tissue plasminogen activator is more activated.

IPC Anticoagulant Mechanism

The comparison of IPC and Compression stocking

IPC Compression stocking DVT prevention effects

-It is evidenced as the most effective from physiological prevention of DVT. -As it is lesser than anticoagulant drugs but higher effects than stocking, for high risk group, it is better to use with anticoagulant drugs.

-It is effective for DVT prevention but it is lesser than IPC from clinical studies.

Strong point - It is evidenced as the most effective from physiological treatments. - As a patient can feel refresh by soft compression massage, the satisfaction is higher than bandage or stocking from clinical studies. - Complication has no nearly in comparison with stocking or coagulant. (It is required prevention treatment for a patient who can have any complication of bleeding by coagulant drug like heparin or warfarin.) - It can be used optionally with stocking or coagulant drug.

- It is easy for a patient who is movable to use stocking and inexpensive. - It can be used with IPC or coagulant drug.

Weakness A patient should use it at the only bed. - A patient can feel discomfort by itchy or heated. - It can make a side effect like homeostasis effects. - It is not recommended for serious edema, diabetic, diseases related to a peripheral nerve or venous. - It can be used for the only low risk group.

Purpose

This experiment is to make a comparison between IPC and the underfoot pump in the preventive effect against traumatic DVT.

Subjects and Methods:

149 patients with massive trauma were divided into two groups; a IPC group and a an underfoot-pump group. The observer did not know what preventive

measures to take. The bilateral pressure-ultrasonic scanning was performed on all the patients within 8 days after they were grouped.

Results

IPC was applied to 62 patients out of 149 who were randomly grouped. To the other 62 patients, the underfoot pump was applied. In the case of the foot

group, DVT occurred in 13 patients (21%). In the case of the leg group, DVT occurred in 4 patients (6.5%) (p=0.009). Out of the 13 patients who got

DVT in the foot group, 7 got DVT in both feet. In the leg group, there was no case where DVT occurred in both legs.

Evaluation

IPC is light on hand, and does not cause complications, e.g., hemorrhage. It can effectively prevent DVT whether it is used independently or concurrently

with other things. In all of studies, it has been reported that early training, the underfoot pump (for edema) and elastic (pressure) pants are used to lower

the onset rate of DVT. However, the problem is that such things cannot work sufficiently. Thus when such things are used in combination with IPC or other

chemical (or pharmacological) methods, remarkable effects come out.

The DVT-2600 can be used for DVT prevention before, during and after surgery.

On its own, the DVT-2600 system can be used as the alternative medicine for a stroke patient, a patient who can’t use oral administration or any patient who can not use anticoagulant (heparin or wafarin) to prevent DVT and PE.

The DVT-2600 can be used in conjunction with anticoagulants or compression stockings. Typically compression stockings are used as an adjunct to the IPC therapy.

DVT-2600 for DVT prevention before, during and after surgery

Intermittent pneumatic compression

(IPC) machines use air bladders that are

wrapped around the thigh, calf or foot.

The bladders alternately inflate and deflate,

squeezing the muscles and increasing

blood velocity by as much as 500%.

IPC machines have been proven effective

for the prophylaxis of DVT.

DVT-2600 for DVT prevention before, during and after surgery

Beijing university (Anesthesia department) tested Deep vein thrombosis generation rate with the ultrasonography system for 3~10days to 233 patients after serious operations. The test result was reported that DVT detect rate was 47.64% similar as the DVT detection rate in overseas studies or test results.
