Detachable device for preventing deep venous thrombosis of upper and lower limbs

Abstract

The invention discloses a detachable device for preventing deep venous thrombosis of upper and lower limbs. The device comprises a control box, and a temperature sensing mechanism, a control switch, an alarm mechanism, a timing mechanism, a display mechanism and a wearing mechanism that are arranged on the control box. When the device is used, the extended wearing mechanism worn on a patient is set and monitored in real time by the temperature sensing mechanism, the control switch, the alarm mechanism, the timing mechanism and the display mechanism, and large-area extrusion and massage are performed on the skin of the four limbs of the patient by using the wearing mechanism, to increase the venous blood flow speed of the patient with a venous thrombosis risk, thereby increasing the blood flow speed, and thus, blood stasis is avoided, and then the treatment effect of preventing DVT and PE is achieved. The device has the characteristics of being high in intelligent degree, detachable and capable of monitoring the blood flow condition of the upper and lower limbs of the patient in real time.

Description

technical field [0001] The invention relates to the technical field of rehabilitation physiotherapy equipment, in particular to a detachable device for preventing deep vein thrombosis of upper and lower extremities. Background technique [0002] Venous thromboembolism (VTE) includes deep venous thrombosis (deep venous thrombosis, DVT) and pulmonary thromboembolism (pulmonary thromboembolism, PTE). DVT and PTE are two clinical manifestations of the same disease at different stages of VTE. The onset can range from asymptomatic to sudden sudden death. It is a common and serious complication that threatens the life of hospitalized patients, but it is also a completely preventable hospital-acquired disease; [0003] The main clinical thrombosis prevention methods are the use of drug prevention and mechanical prevention, and the main effect of drug anticoagulation is clear; but for critically ill patients, especially medical critically ill patients, because they are not as clear a...

Problems solved by technology

[0005] At the same time, the existing IPC device is not reasonable enough and inconvenient to use (the air pressure pump is too large and heavy, and needs to be plugged in instead of a battery); for clinicians: it is impossible to evaluate and identify the importance of its use; Dynamic observation at one time; for nurses: the need to control the IPC time virtually increases the nursing workload; for patients: no relevant health education for patients; patients' intolerance to air pressure during use, Material allergies and noise interference sleep caused by air pump work can not be the first time feedback; in addition to judge the curative effect, you can measure the peak of femoral vein blood flow, the average velocity of femoral vein and the change of plasma viscosity, and collect the patient's fasting elbow Central venous blood, 5mL is placed in a test tube, centrifuged after standing for 5min, the supernatant is collected, and the plasma viscosity is measured; it will bring pain and economic cost to the patient virtually; any type of deep vein thrombosis of the lower extremities can be detected by angiography or vascular color Doppler ultrasound Pulmonary embolism with or without symptoms can be determined by pulmonary ventilation perfusion scan or computed tomographic pulmonary angiography (CTPA) or autopsy; traditional venous interventional angiography is the gold standard for diagnosing DVT, but DSA is an invasive Ultrasound (US) detection of DVT is highly accurate and non-invasive. It is inexpensive and can be repeated. Therefore, ultrasound is widely used in clinical practice.

Almost completely replaced venography, however there are some limitations
