Description
Technical Field
The invention relates to the technical field of rehabilitation physiotherapy equipment, in particular to a detachable device for preventing upper and lower limb deep vein thrombosis.
Background
Venous Thromboembolism (VTE) comprises Deep Venous Thrombosis (DVT) and Pulmonary Thromboembolism (PTE), the DVT and the PTE are two clinical manifestations of the same disease VTE at different development stages, the onset of the disease can range from asymptomatic to sudden death, and the disease is a common and serious complication threatening the life of inpatients, but is also a hospital acquired disease which can be completely prevented;
the clinical main thrombus prevention is a method of using medicine prevention and mechanical prevention, and the main effect of the anticoagulation of the medicine is clear; however, critical patients, especially medically critical patients, are not focused on the prevention of thrombus because they have definite antithrombotic indications rather than surgical patients, and the use of anticoagulation drugs is limited because the severity of the disease may present contraindications to the use of anticoagulation drugs or may bring high bleeding risk due to the use of anticoagulation drugs; although clinicians have long recognized the importance of thrombus prevention for operation patients, the prevention of VTE of internal medicine patients, particularly critically ill patients, is still insufficient, and only 18% -67.5% of internal medicine critically ill patients receive thrombus prevention treatment, firstly, because the internal medicine patients, particularly critically ill patients, have complicated and variable conditions and are difficult to identify high-risk factors of VTE, and secondly, the evidence of VTE prevention of internal medicine hospitalized patients is lacking, and the consciousness of doctor prevention is deficient;
whether the Chinese expert advice published in 09 years or the ninth version of antithrombotic guideline published by the American society of thoracic physicians in 2012 (ACCP9) proposes that different thrombus prevention advice is given to medical inpatients according to the layering of thrombus risk assessment, and the modes mainly comprise mechanical prevention and medicinal prevention; the mechanical method is recommended to be used for preventing patients who do not have contraindication of mechanical preventive treatment, have contraindication of anticoagulation drug treatment and have better anticoagulation treatment effect on hemorrhagic stroke or ischemic stroke; although some large random control studies confirm the effectiveness of medical anticoagulation for preventing VTE of medical inpatients, the medical inpatients, particularly severe patients combined with other multiple thrombus risk factors and the use of anticoagulation drugs on the risk factors can bring about the risk of heavy bleeding and are limited, so that a definite and effective antithrombotic replacement method is urgently needed by medical critical patients; according to the thrombus guideline, research and research are suggested to find that mechanical prevention accounts for 36% -53% of critical patients in medical department who obtain thrombus prevention and treatment, wherein an Intermittent Pneumatic Compression (IPC) is the most important mode; but the recommended guidelines for IPC prevention of venous thromboembolism at home and abroad indicate that IPC is one of the most common physical methods; the mechanism is mainly to increase venous blood flow or reduce stasis of venous blood flow of legs and prevent the formation of lower limb thrombus; compared with anticoagulant drugs, the anticoagulant drug has the advantages of no increase of bleeding risk, no wound, economy and the like, and has particular advantages for patients with high bleeding risk; although the prevention of VTE in surgical patients has been paid more attention, the prevention of VTE in hospitalized patients without obvious antithrombotic index has not been paid enough attention, particularly severe internal medicine patients with various VTE risk factors are easy to suffer thrombotic diseases, so safe and effective venous thrombosis prevention measures are urgently needed to research the characteristics that physical and mechanical prevention has no wound and bleeding risk, and critical patients with poor renal function do not need to monitor blood concentration and the like, most common are intermittent Inflation and Pressurization (IPC), venous pump (VFP), gradient pressure elastic stocking (GCS) or Elastic Stocking (ES), wherein, IPC is most commonly used and has been widely used for various surgical patients to prove the effectiveness of the prevention of thrombus, but the existing facilities have certain disadvantages and need to be redesigned urgently;
meanwhile, the existing IPC device is not reasonable enough and is inconvenient to use (the pneumatic pump is too large and heavy, and a power supply is required to be plugged instead of a battery); for the clinician: the importance of the use of the medical instrument cannot be evaluated and identified; dynamic observation can not be carried out at the first time; for the nurse: the IPC time needs to be invisibly controlled, so that the nursing workload is increased; for the patient: no relevant health education was performed on the patient; the first time that the patient cannot tolerate the air pressure in use, the material allergy and the noise caused by the work of the air pressure pump interfere the sleep and the like is time feedback; in addition, judging how the curative effect is, collecting the fasting elbow venous blood of a patient by measuring the femoral vein blood flow peak condition, the femoral vein average speed and the blood plasma viscosity change, placing 5mL of the fasting elbow venous blood in a test tube, standing for 5min, then performing centrifugal treatment, collecting supernatant, and measuring the blood plasma viscosity; the pain and the economic cost are brought to the patient invisibly; any type of deep vein thrombosis of the lower extremities is diagnosed by angiography or angiography, with or without symptoms of pulmonary embolism determined by pulmonary ventilation perfusion scan or pulmonary angiography (CTPA) or autopsy; conventional veno-interventional radiography is the gold standard for diagnosing DVT, however DSA is an invasive examination with ionizing radiation, Ultrasound (US) detects DVT with high accuracy and non-invasiveness, examination cost is inexpensive, and repeated examination is widely used clinically. Almost completely replaces intravenous imaging, however, there are certain limitations.
Disclosure of Invention
Aiming at the existing problems, the invention aims to provide a detachable device for preventing upper and lower limb deep vein thrombosis, the device sets and monitors a wearing mechanism worn on a patient in real time through a temperature sensing mechanism, a control switch, an alarm mechanism, a timing mechanism and a display mechanism, and utilizes the wearing mechanism to squeeze and massage the skin of four limbs of the patient in a large area so as to increase the venous blood flow velocity of the patient with venous thrombosis risk, thereby increasing the blood flow velocity, avoiding blood stasis and further achieving the treatment effect of preventing DVT and PE.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
a detachable device for preventing upper and lower limb deep vein thrombosis comprises a control box, a temperature sensing mechanism, a control switch, an alarm mechanism, a timing mechanism, a display mechanism and a wearing mechanism, wherein the temperature sensing mechanism, the control switch, the alarm mechanism, the timing mechanism, the display mechanism and the wearing mechanism are arranged on the control box;
the temperature sensing mechanism is used for sensing the body surface temperature of the user and displaying the body surface temperature through the display mechanism;
the control switch is used for controlling the opening and closing of a main controller of the control box;
the alarm mechanism is used for monitoring the skin color change of the position where the patient wearing mechanism is located and giving an alarm;
