Description
Technical Field
The invention relates to the technical field of rehabilitation physiotherapy equipment, in particular to a detachable device for preventing deep venous thrombosis of upper and lower limbs.
Background
Venous thromboembolism (venous thromboembolism, VTE) includes deep vein thrombosis (deep venous thrombosis, DVT) and pulmonary thromboembolism (pulmonary thromboembolism, PTE), DVT and PTE are two clinical manifestations of the same disease VTE in different stages of development, the onset of which can range from asymptomatic to sudden death, is a common, serious complication threatening the life of hospitalized patients, but it is also a fully preventable hospital acquired disease;
the main clinical thrombus prevention is a method using medicine prevention and mechanical prevention, and the main effect of medicine anticoagulation is clear; however, for critical patients, especially medical critical patients, the prevention of thrombus is not emphasized because of the fact that the critical patients have clear anti-thrombus indications as compared with surgical patients, and further, the use of anticoagulants is limited because of the possible contraindication of the use of anticoagulants or the risk that the use of anticoagulants may bring about high bleeding due to the severity of the disease; although clinicians have long appreciated the importance of preventing thrombosis to surgical patients, the prevention of VTE in internal patients, particularly critically ill patients, is still significantly insufficient, and only 18% -67.5% of critically ill patients in internal medicine receive thrombus prevention treatment, firstly, because the conditions of the internal medicine patients, particularly critically ill patients, are complex and changeable, and the high-risk factors of VTE are difficult to identify, secondly, the evidence-based medical evidence of VTE prevention in internal medicine inpatients is lacking, and the prevention consciousness of doctors is lacking;
whether "Chinese expert advice" issued in 09 years or ninth anti-thrombus guidelines issued in 2012 by the American society of pectoral physicians (ACCP 9) propose different advice for thrombus prevention to medical inpatients based on stratification of thrombus risk assessment, the modes mainly include mechanical prevention and pharmaceutical prevention; mechanical method prevention is recommended for patients who do not have mechanical preventive treatment contraindication, have contraindication for anticoagulation medication, and have greater disadvantage in hemorrhagic stroke or ischemic stroke anticoagulation treatment; although some large randomized controlled studies have demonstrated the effectiveness of drug anticoagulation to prevent VTE in medical hospitalization patients, the use of anticoagulants in medical hospitalization patients, particularly in critically ill patients who incorporate other various thrombotic risk factors, may be limited by the risk of major bleeding, and therefore a clear and effective anti-thrombotic replacement therapy is highly desirable in medical critically ill patients; according to the thrombus guidelines, research and study are suggested, and mechanical prevention accounts for 36% -53% of medical critical patients who obtain thrombus prevention treatment, wherein an intermittent inflation pressure pump (intermittent pneumatic compression, IPC) is the most dominant mode; however, the recommended guideline for preventing the venous thromboembolism at home and abroad is indicated in IPC, which is one of the most commonly used physical methods; the mechanism is mainly to increase venous blood flow or reduce stasis of leg venous blood flow and prevent lower limb thrombosis; compared with anticoagulant drugs, the preparation has the advantages of no increase of bleeding risk, no invasiveness, economy and the like, and is particularly advantageous for patients with high bleeding risk; although the VTE prevention of surgical patients has been paid more attention to, the prevention of VTE of hospitalized patients in internal medicine without obvious antithrombotic index is still lacking in attention, especially severe internal medicine patients frequently accompanied by various VTE risk factors are more likely to suffer from thrombotic diseases, so that safe and effective venous thrombosis prevention measures are urgently required to explore and study the characteristics of physical and mechanical prevention, such as no wound, no bleeding risk, no need of monitoring blood concentration and the like for critical patients with poor renal function, most common are intermittent inflation pressurization (intermittent pneumatic compression, IPC), plantar venous pump (VFP), gradient pressure elastic socks (graded compression stocking, GCS) or elastic socks (elastic stockings, ES), wherein IPC is most commonly used, has been widely used for various types of surgical patients to prove the effectiveness of thrombus prevention, but the facilities have certain drawbacks and are urgently required to be redesigned at present;
meanwhile, the existing IPC device is not reasonable enough and inconvenient to use (the pneumatic pump is too large and heavy, and a power supply is needed to be inserted instead of a battery); for a clinician: the importance of the use of the device cannot be evaluated and identified; dynamic observation cannot be performed at the first time; for nurses: the care workload is increased in the control of IPC time; for patients: no related health education is performed on the patient; intolerance to air pressure, material allergy, noise caused by air pressure pump work, sleep disturbance and the like in the use of a patient cannot be first time feedback; in addition, judging how to treat the disease, collecting the fasting elbow venous blood of a patient by measuring the peak condition of femoral venous blood flow, the average speed of femoral venous blood flow and the change of plasma viscosity, placing 5mL into a test tube, standing for 5min, centrifuging, collecting supernatant, and measuring the plasma viscosity; intangibly causing pain and economic expense to the patient; any type of deep vein thrombosis of the lower limb is diagnosed by angiography or vascular ultrasound, and the presence or absence of a symptomatic pulmonary embolism is determined by pulmonary ventilation perfusion scanning or pulmonary angiography (computed tomographic pulmonary angiography, CTPA) or autopsy; traditional intravenous interventional imaging is the gold standard for diagnosing DVT, however DSA is an invasive examination with ionization radiation, ultrasound (US) for detecting DVT is highly accurate and non-invasive, the examination cost is inexpensive, repeated examination is thus the ultrasound is widely used clinically. Almost completely replaces intravenous imaging, however, there are certain limitations.
Disclosure of Invention
Aiming at the problems, the invention aims to provide a detachable device for preventing deep venous thrombosis of upper and lower limbs, which is characterized in that a wearing mechanism which is worn on the extension of a patient is arranged and monitored in real time through a temperature sensing mechanism, a control switch, an alarm mechanism, a timing mechanism and a display mechanism, and the limb skin of the patient is extruded and massaged in a large area by the wearing mechanism to increase the venous blood flow speed of the patient with venous thrombosis risk, so that the blood flow speed is increased, blood stasis is avoided, the therapeutic effect of preventing DVT and PE is achieved, and the device has the characteristics of high intelligent degree, detachability and capability of monitoring the blood flow condition of the upper and lower limbs of the patient in real time.
In order to achieve the above purpose, the technical scheme adopted by the invention is as follows:
